        <description>So what then does Resurrection mean? For Benedict it represents a new dimension of reality breaking through into human experience. It is not a violation of the old; it is the manifestation of something new.</description>
        <content:encoded><![CDATA[<p>The scientific case against resurrection is pretty straightforward: once dead you stay dead -- that's just the way it works. Coming back to life after having been dead (I mean <em>really</em> dead) would constitute a violation of natural law -- a miracle -- and miracles just don't happen. Fair enough. But in his recent book on the last days of Jesus (<em>Jesus of Nazareth Holy Week: From the Entrance Into Jerusalem to the Resurrection</em>), Joseph Ratzinger (aka Pope Benedict XVI) argues that reckoning Resurrection as resuscitation of a corpse is to misunderstand its true significance. Jesus' Resurrection, he contends, was an utterly singular event, straining the very limits of human understanding:</p>

<p>"Anyone approaching the Resurrection accounts in the belief that he knows what rising from the dead means will inevitably misunderstand those accounts and will then dismiss them as meaningless" (p. 243).</p>

<p>In fact, if Jesus' Resurrection were "merely" coming back to life in any way that we might comprehend, then it would be of little significance.</p>

<p>"Now it must be acknowledged that if in Jesus' Resurrection we were dealing simply with the miracle of a resuscitated corpse, it would ultimately be of no concern to us" (p. 243).</p>

<p>So what then does Resurrection mean? For Benedict it represents a new dimension of reality breaking through into human experience. It is not a violation of the old; it is the manifestation of something new.</p>

<p>"Jesus had not returned to a normal human life in this world like Lazarus and the others whom Jesus raised from the dead. He has entered upon a different life, a new life -- he has entered the vast breadth of God himself..." (p. 244).</p>

<p>Because it is something entirely new, it cannot represent a violation of natural law as understood by science.</p>

<p>"Naturally there can be no contradiction of clear scientific data. The Resurrection accounts certainly speak of something outside our world of experience. They speak of something new, something unprecedented -- a new dimension of reality that is revealed. What already exists is not called into question. Rather we are told that there is a further dimension, beyond what was previously known. Does that contradict science? Can there really only ever be what there has always been? Can there not be something unexpected, something unimaginable, something new? If there really is a God, is he not able to create a new dimension of human existence, a new dimension of reality altogether?" (p. 246-7)</p>

<p>Thus, in this view, Resurrection (as with all true miracles) is not contrary to science, but an indicator that science does not (yet?) describe the full expanse of reality. Indeed, some may argue that science itself contains similar "indicators." The 11 (or so) dimensional universe required by some versions of string theory, the multiverse theory of the universe where ours is but one of an infinite array of universes with variable physical laws, quantum entanglements, "spooky" action at a distance, the mysterious emergence of consciousness from inorganic matter -- all push the limits of human reason and imagination, suggesting to some that reality may be far more complex than the human mind can grasp.</p>

<p>For a moment, let us entertain the possibility that Resurrection is as Benedict interprets it: not a violation of natural law but an indicator of something beyond our scientific understanding of the universe. This has interesting implications for understanding how believers and skeptics approach the issue. If Resurrection does not violate science, then science does not necessarily constitute an impediment to accepting the reality of Resurrection. If the difference between the skeptic and believer is not science, then is it just a matter of imagination? The believer imagines greater possibilities for the universe than the non-believer. While this is possible, it seems questionable. To my knowledge, no research has found differences in imaginative abilities between religious and non-religious people. Moreover, contrarian examples easily come to mind: Isaac Asimov was an atheist but hardly lacking in imagination when it came to science fiction. I tend to think that both believers and non-believers can imagine (with varying degrees of effort, I'm sure) the new possibilities implied by Resurrection.</p>

<p>Thus, if it is neither imagination nor science that prompts skepticism about Resurrection, then what is left? I suggest that it comes down to a question of authority: At what point does one allow imaginative possibilities to have authority over how one lives? To the believer, Resurrection has an authority that science fiction does not. Resurrection is not thought-provoking entertainment. It requires far more than just imagining greater possibilities for the universe. It requires a change of life, here and now. Unlike the microscopic hidden dimensions of string theory, the new dimension implied by Resurrection has "broken though" into everyday reality and demands a response -- even if that response is to actively ignore it.</p>

<p>Now, what convinces the believer that Resurrection merits such authority when other imaginative possibilities such as extraterrestrial life or time-travel do not? The answer here appears to be historical commitment. There's no record of people committing themselves to the point of martyrdom to other imaginative possibilities as they have to Resurrection. The earliest example of such commitment being found, of course, in the dramatic post-crucifixion turn-around of the Apostles. Such an astounding change of heart, followed by an unwavering commitment capable of altering human history demands a categorically unique explanation: Resurrection.</p>

<p>The believer's argument, however, remains unconvincing to the skeptic. However impressive they might be, a change of heart and steadfast commitment do not necessarily add up to a new dimension of reality. Extraordinary claims require extraordinary evidence. Fair enough. So a key question regarding the interpretation of Resurrection is this: Is the post-crucifixion history of Christianity extraordinary? Does it compel the dispassionate observer to concede that a categorically unique event could plausibly be its best explanation?</p>

<p>It ought to be upon questions such as those above that skeptics and believers respectfully engage one another, rather than the simplistic and often acrimonious sloganeering that has increasingly become the norm.</p>

        <title>A Scientific Commentary on Genesis 7:11</title>
        <link>http://biologos.org/blog/a&#45;scientific&#45;commentary&#45;on&#45;genesis&#45;711?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>

        <description>Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood. Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet.</description>
        <content:encoded><![CDATA[<p><strong>Genesis 7:11</strong>: In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.</p>

<p><strong>Genesis 8:1</strong>: But God remembered Noah and all the wild animals and all the domestic animals that were with him in the ark. And God made a wind blow over the earth, and the waters subsided; 2 the fountains of the deep and the windows of the heavens were closed, the rain from the heavens was restrained, 3 and the waters gradually receded from the earth.</p>

<hr />

<p>The Flood narrative of Genesis 7-9 has played a prominent role in science and religion debates for over three hundred years and gave rise in earlier centuries to geological theories such as old earth catastrophism. While literary studies have uncovered the chiastic structure of the Flood story (see Gordon Wenham, “The Coherence of the Flood Narrative” Vetus Testamentum 28 (1978):336-48) and with it the theological pivot point of the entire narrative (Gen. 8:1 – “And God remembered Noah…), much of the popular attention remains on the questions regarding details (Is there THAT much water in the world to cover ALL the mountains to a depth of 15 cubits? Could you really fit two or seven of every animal species in an ark that size?) </p>

<p>Looking at a smaller matter, we find at the beginning and the middle of the narrative indications of an ancient Near Eastern worldview. As the story is told, the flood was not merely the result of excessive rain, but actually the convergence of the waters above the earth with the waters below the earth. It is, as one translation puts it, as if the sluice gates at the deep and of the heavens were thrown open and water poured in from above and below. This is a consistent picture from the Old Testament of a three-tiered universe—a dome above the earth holding back the heavenly waters, a flat earth with water on its surface, and water under an earth which is held up by pillars. </p>

<p>That the story is told using the cosmology of its time should not be unduly unsettling, nor that the story is reinterpreted as new understandings of the universe come into favor. By way of example, consider John Calvin and his understanding of the structure of the universe. Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood.   </p>

<p>Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet. Calvin still subscribed to the common conception of his day in which the four elements—earth, air, fire, and water—comprised the earthly sphere and possessed unique characteristics. The nature of air and fire was to rise, while the nature of earth and water is to sink.  Earth, being heavier than water, should sink to the center of the cosmos and water should compose the next layer. Both earth and water are spherical, i.e., naturally form spherically around the cosmic center. Thus the heavier spherical element of earth should be encased entirely within the lighter spherical element of water.</p>

<p>Notice what this does to the flood story. For Calvin, the amazing thing is that the world isn’t constantly under water and subject to flooding. In the cosmology of Calvin’s day, it does not take an act of God to cause a universal flood, but rather an actively present and restraining hand of God to keep the waters back in everyday circumstances and make inundation by water something other than universal. </p>

<p>Obviously, Calvin was wrong. Or perhaps we should say that medieval cosmology was flawed and justifiably gave way to new conceptions of the universe. The answer is not to return to an ancient Near Eastern cosmology, but to reinterpret cautiously within new and better cosmologies and to pay closest attention to the text and the theology of scripture.  </p>

<p>The geological and planetary sciences bring their own unique contributions and are of more interest than the latest expedition to discover the ark on Mt. Ararat. Is the flood story a universalization of a catastrophic regional event that burned itself into the psyche of ancient cultures in the Mediterranean basin? Various theories regarding a Black Sea venue for a catastrophic flood event are still in process of being sorted out. It’s intriguing. Or the question where the water on Planet Earth comes from? Was it always here as an emanation of vapors from the earth’s crust in its early formation, or has it accumulated over eons through the steady bombardment of earth by small, icy comets? It’s an intriguing scientific question that is in the midst of determination through testing.</p>

<h3>Preaching Suggestions</h3>

<p>When preaching on the story of the Flood, it is easy to get lost in the debates over particulars. As mentioned elsewhere, to tackle all the peripheral issues threatens to turn a sermon into a geology lecture. Other settings are better suited to addressing those questions, and those are best addressed open-endedly. </p>

<p>A brief explanation of ancient Near Eastern cosmology can be helpful to contextualize the story. If there are those who are tempted to think that a cosmology embedded in the Bible must be inspired and definitive, one can note that cosmology has changed by the New Testament. The Bible itself isn’t wed to a particular structure of the universe. </p>

<p>What is important is to keep the theology of the text front and center, and in that theology there are at least three non-negotiables from the flood narrative. First, human sin and violence threatens to undo a good creation (the flood is a de-creation event, a return of the waters mentioned in Genesis 1:2). Second, God remembers Noah, and never forgets his promises. Third, the end of the flood is a covenant with the whole earth regarding the stability and endurance of the natural order.

        <title>Series: Harmonizing Science, Ethics, and Praxis</title>
        <link>http://biologos.org/blog/series/harmonizing&#45;science&#45;ethics&#45;and&#45;praxis?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>
        <guid>http://biologos.org/blog/series/harmonizing&#45;science&#45;ethics&#45;and&#45;praxis?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>In this three&#45;part series, Cal DeWitt offers insights and examples of why science and ethics must work together to help us make informed, practical decisions within our society.  DeWitt’s science&#45;ethics&#45;praxis model provides a framework by which we can live more effectively as God’s stewards.</description>
        <content:encoded><![CDATA[<h3>The Science-Ethics-Praxis Triad</h3>

<p>Today, as I write, I am no longer in the desert of southern California, nor in the beech-maple forest of New Hampshire, but on a glacial drumlin in Waubesa Wetlands—a large marsh four miles south of Madison, Wisconsin. Here Ruth and I have our home, and here I study creatures whose watery habitats my neighbors and I have worked to save from eventual destruction. While my desert study site now is covered by a city where people live alone in the land—absent the desert creatures—my wetland study site remains occupied by all kinds of native plants and animals. Embracing it is the Town of Dunn, whose land stewardship plan helps people understand, serve, and maintain this and the other ecosystems. Our town stewardship plan encourages restoration of the landscape, protects agricultural lands, and strives to transmit an intergenerational heritage of secure and wholesome homes, livelihoods, and habitats for the animals, plants, and people that live here. We live largely in harmony and accord. </p>

<p>House-building on slabs poured onto desert sands first alerted me to the question of praxis, the third point on the napkin. But it was later, in my work as organizer of the Waubesa Wetlands Scientific and Agricultural Preserve, and as supervisor and later as chair of the Town of Dunn, that I came to realize that science and ethics do no earthly good unless put into practice. In serving my town, I came to apply what I had learned in the desert: praxis uninformed by science and ethics usually creates more problems than are solved.</p>

<p>“How do you put it all together?” those students in New Hampshire wanted to know. For me, it was building a framework for stewardship that simultaneously considered the questions “How does the world work?” “What is right?” and “What then must we do?” This science-ethics-praxis triad is a framework for living, for learning, for teaching, and most importantly for acting. It is a framework for stewardship.</p>

<p>In order to live and act rightly in the world, we need to know how the world works. We need to know how the systems that sustain us work, and how we interact with them. Without such knowledge we could drown in a flash flood, have our homes undercut by desert winds, cross the street in the path of an oncoming car, or get sick from consuming foods with toxic ingredients. As human beings develop more and more of the world, and as the reach of human actions extends regionally and globally, our knowledge must increase accordingly. This knowledge is not limited to what we acquire from a formal education; it also includes the knowledge we gain from family and friends, and from experience and experiment. In order to live and act rightly in the world, we need to know how the world works.</p>

<p>In order to live and act rightly in the world, we need to know what we ought to do. A century ago, this question was addressed in many colleges across America in a course for graduating seniors on moral philosophy. The purpose of this course was to convict students that they should apply their knowledge for the pursuit of good instead of pursuing self at others’ expense. At my university, this aspect of college education is expressed in a quotation from Abraham Lincoln carved in stone on a bench behind Lincoln’s statue at the top of Bascom Hill: “Let us have faith that right makes might, and in that faith, dare to do our duty.” The question “What is right?” is represented by the ethics corner of our triad. Moving directly from the Science corner to the praxis corner, or from the ethics corner to the praxis corner, proves problematic, even disastrous. Consider the result of going from knowledge of nuclear fission (science) directly to producing and dropping an atomic bomb (praxis), or moving from the belief that death is bad (ethics) to removing dead wood from forests (praxis); both are examples of these disastrous shortcuts.</p>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/DeWitt_Cover_thumb.jpg" alt="" height="270" width="200"  /></p>

<p>But knowing the science and observing the ethics of this stewardship framework does absolutely no good if it is not put into practice—placed into service. By themselves, the very best science and the most substantial ethics are no substitutes for action. We need to act appropriately and deliberately in the light of scientific and ethical knowledge. Praxis by itself, without being grounded in science and ethics, results in mere activism—activism that is unlikely to do good and that may produce harm. All three corners of the triad are essential—but not by themselves. Taken together and working interactively, they provide a framework for stewardship.</p>

<p>But will these three operate in dynamic interaction? Will they interact in ways that preserve and achieve the integrity of human life and the environment? The answer depends on what we know and understand about ourselves and the world (science), what we believe we should do (ethics), and what we in fact do, and how we respond to our successes and failures (praxis). It depends on our will, our motivation, our determination, and our dedication to strive for a harmonious world of creatures before their Creator. What might make us strive for such a world?</p>

<p class="intro">Part 3 explores the challenge of translating ideals into concrete actions.</p>

        <title>Introducing the BioLogos Navigator</title>
        <link>http://biologos.org/blog/introducing&#45;the&#45;biologos&#45;navigator?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>
        <guid>http://biologos.org/blog/introducing&#45;the&#45;biologos&#45;navigator?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>Part of BioLogos mission is to show how all things hold together in Christ—to show how a Christian worldview integrates the knowledge we have of God through the Scriptures with the knowledge we have of God through the other areas in which He reveals himself as Creator and Redeemer.</description>
        <content:encoded><![CDATA[<p>When we at BioLogos affirm that, “all things hold together in Christ,” what do we mean?  In short, we believe that there is no aspect of creation or of human experience that does not fall under the sovereignty and authority of God, and that He does not claim for himself and intend for redemption.  After all, at his resurrection, Jesus himself said, “All authority in heaven and on earth has been given to me” (Matthew 28:18). But more than just proclaiming God’s sovereignty over creation, we believe that God is revealing himself in every aspect of creation, as well—that led by the Holy Spirit, we will find pointers to God wherever we turn our gaze.  Christian knowledge, therefore, is not limited to the study of the Scriptures or of Church History, but includes the study of the natural world and of all of human culture, as well.  In fact, to fully appreciate God’s abundant grace and providence, we need to be looking to all of these domains of knowledge as domains of revelation, too. </p>

<p>Part of the BioLogos mission, then, is to show <em>how</em> all things hold together in Christ—to show how a Christian worldview integrates the knowledge we have of God through the Scriptures with the knowledge we have of God through the other areas in which he reveals himself as Creator and Redeemer.  Our website contains a wealth of Christian scholarship in a wide range of fields—from biology, to cosmology, to mathematics, to Biblical studies, to history, to theology—all demonstrating that the best contemporary science is compatible with Biblical Christian faith. But today we introduce a new tool—the BioLogos Navigator—to make these posts more accessible, and to show how they inter-relate (see sidebar on the right).  </p>

<p>Modeled on the astrolabes that early astronomers and sailors used to orient themselves under the heavens, our Navigator makes the cross of Christ the starting point by which we understand the cosmos.  Each of the four arms of the cross represents one of the domains of knowledge and experience through which God reveals himself to the world: Scripture, the Church, Nature and Culture.  These domains are not in opposition to each other, but are complementary and inter-related areas through which we can recognize God at work in the world. Linking these four domains is a network of specific topics relevant to the science and faith conversation.  Their arrangement suggests how each relates to the four domains but also to teach other.  Clicking on an individual topic tag highlights not only that topic, but other topics that are linked to it—sometimes in unexpected ways.</p>

<p>Clicking a topic tag a second time takes you to the Topic Landing page: a curated selection of the best resources on that subject from the BioLogos archives.  (The image above shows the <em><a href="http://biologos.org/navigator/Christianity+&+Science+-+Then+and+Now">Christianity & Science—Then and Now</a></em> Landing page, complete with Navigator and highlighted tags.) At the bottom of each page is a link to our Resource Finder, where you can investigate additional materials on that topic, as well. By exploring the relationships between the topics on the Navigator itself, and by delving deep into each topic via the resources presented on the landing pages, readers can focus on specific aspects of the harmony between science and Christian faith while also getting the wide view of God’s providential work in all things in the heavens and on the earth. </p>

<p>In the coming days and weeks, the BioLogos Navigator will be more fully integrated into the rest of the site, accessible directly from the Forum homepage and from the Resources dropdown list at the top of every page.  We’ll also be including features that help place each blog post on the “knowledge map” defined by the domains and topic tags.  Finally, the Topic Pages will also be periodically updated with the latest and best new materials in each topic. In the meantime, <strong>you can access the Navigator by clicking anywhere on the small image in the sidebar, above</strong>, and find a link to this post at the upper right corner of our homepage.  So take some time to explore our site with this new tool, which we think will to help orient our readers in the science and faith conversation, while always pointing to Jesus, the Christ, through whom all things were made.</p><br />]]></content:encoded>

        <content:encoded><![CDATA[<p>As an evangelical scientist, Katharine Hayhoe is already a member of a rare breed.  As a climate change researcher who is also married to an evangelical Christian pastor, she is nearly one of a kind.  In these three videos, Hayhoe divulges her beliefs about God, climate change, and the difficulties of believing in both those things.</p>

<p>The first video, “10 Questions with Katherine Hayhoe”, introduces the scientist in a brief and lighthearted interview.  Hayhoe is presented with 10 questions concerning her personal life and beliefs.  When asked, she explains that one thing people should know about Christianity is that having a relationship with the God of the universe is one of the most incredible experiences that a person can have. As the video unfolds, the viewer quickly begins to realize that, despite her unique profession of two seemingly incompatible beliefs, Hayhoe is a remarkably sane and “normal” individual.  Her role model, she explains, is her father-- the person who first introduced her to science and showed her that it could be “really cool”.  On a more serious note, the scientist admits that being both a scientist and a Christian can be difficult.  The most frustrating thing about her position, she says, is the amount of disinformation which is targeted at her very own Christian community.</p>

<p>In the second video, “Climate Change Evangelist”, Katharine Hayhoe delves into deeper discussion of the perceived conflict between climate change and Christian faith.  She explains that admitting her identity as a Christian scientist can be uncomfortable.  Since evangelicals are the targets of much disinformation concerning science in general -- and specifically the science surrounding climate change -- many people in the church have a misguided view of the subject and do not look kindly at her career choice.  One woman encountered by Hayhoe at a church in Texas, for example, believed that global warming was a lie taught in schools to mislead her children.  In an effort to realign misguided views like these, Katharine Hayhoe and her husband wrote a book addressing the deep-rooted emotions often associated with climate change.  People fear that addressing the climate issue will bring forth changes in the economy and uproot their way of life.  However, Hayhoe encourages her viewers to act out of love, as the Bible calls us to do, rather than out of fear.  Acting out of love inspires us to consider the poor and disadvantaged people around the globe when we respond to the reality of a changing climate.</p>

<p>In the final segment of this three part video montage, Hayhoe addresses the question of what climate change means. Specifically, she is concerned about how global warming affects people on a personal level.  While global warming generally brings to mind melting ice caps and polar bears, its implications are far more widespread, affecting the lives of everyone around the world- from cotton farmers in Texas to public health workers in Chicago.  If nothing is done to change current emission levels, the number of days per year which exceed 100 degrees Fahrenheit, for example, will begin to increase dramatically, and if emissions are increased, many areas will even develop extreme conditions like those seen currently in Death Valley.  Hayhoe’s goal is to demonstrate clearly that the only way to preserve the world for future generations is to significantly reduce dependence on inefficient means of getting energy and instead transition to cleaner renewable energy sources.</p>

        <description>Many Christians believe that they face a painful choice&#45;&#45; either life was designed by God or it is an evolutionary product of natural selection.  Charles Darwin himself believed in this dichotomy, and people ever since have felt the need to &quot;choose sides&quot;.  However, looking back at history, we find that one of Darwin&apos;s chief scientific colleagues, Asa Gray, did not share this perspective. In this three&#45;part essay, part 1 charts the relationship of Asa Gray and Charles Darwin.  Part 2 describes Darwin&apos;s struggle with the problem of natural evil and design in nature, and part 3 explores how Asa Gray was able to embrace evolution without rejecting the idea of design.</description>
        <content:encoded><![CDATA[<h3>Asa Gray</h3>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/asa_gray_image_3.jpg" alt="" height="374" width="250"  /><br />Asa Gray</p>

<p>If Thomas Huxley earned the title of "Darwin's bulldog," then Asa Gray should be remembered as "Darwin's dove." Whereas Huxley enjoyed a good fight in his defense of Darwin's theory, Gray sought to mediate and bring sides together around a common understanding of "good science." As Darwin's strongest and most vocal scientific ally in the United States, Gray recognized the scientific importance of Darwin's efforts for the growing professionalism of biological researchers.</p>

<p>But as an orthodox Christian, a Presbyterian firmly devoted to the faith expressed in the Nicene Creed, Gray saw in Darwin's theory both evidence for his philosophical commitment to natural theology and support for his opposition to the idealism advocated by Louis Agassiz and the <em>Naturphilosophen</em> in both Europe and America. Indeed, Agassiz's advocacy of Platonic forms as a basis of biological understanding (e.g., "A species is a thought of the creator")<sup>1</sup> would be a major source of American opposition to Darwin's theory.</p>

<p>Professor of botany at Harvard during most of the middle half of the nineteenth century, Gray was one of the few members of the scientific community to whom Darwin revealed his theory before the publication of <em>On the Origin of Species,</em> and, from what I can tell, the only American. Gray and Darwin met briefly in January 1839 during one of Gray's visits to England. Later, during the 1850s, Darwin wrote Gray on several occasions requesting information--a practice that Darwin frequently employed.  In 1854, Darwin's friend and confidant, Joseph Hooker, showed Darwin Gray's review of Hooker's <em>Flora of New Zealand</em>, in which Gray had argued strongly against Louis Agassiz's idealism and had raised questions from his own work on the stability of species. Gray was not yet ready to deny their permanence, but hybrids and other observations were beginning to trouble him.</p>

<p>The next year Gray wrote a lucid and penetrating positive evaluation of Alphonse De Candolle's two-volume <em>Géographie botanique raisonnée</em>, a pioneering work dealing with plant geography and distribution from a statistical perspective. Hooker had sneeringly dismissed the work. In A. Hunter Dupree's authoritative biography of Gray, he describes Gray's puzzlement at Hooker's response in these terms:</p>

<blockquote>Although in the long view Gray's evaluation of the epoch-making nature of De Candolle's book was more justified than Hooker's sneers, [Gray was confused by his response, for] Hooker seemed to be talking with a more comprehensive theory definitely in mind, some reason for taking his position, which he did not divulge and which his friend [Gray] did not possess.<sup>2</sup></blockquote>

<p>Darwin, however, saw in both Gray's review of Hooker's book and in his comments on De Candolle's tome that Gray was troubled by some of the same empirical data that had been bothering him. In April 1855, Darwin wrote Gray to urge that Gray update his <em>Manual of the Botany of the Northern United States</em> first published in 1848, and especially to address the issue of the range of Alpine plants in the United States. Specifically, he said: "Now I would say it is your duty to generalise as far as you safely can from your as yet completed work."<sup>3</sup></p>

<p>Behind this request was Darwin's desire to test his impression that Gray could make a good ally. Gray passed the test, and finally, in July 1857, Darwin let Gray in on his theory of the transmutation of species. Gray was never an uncritical supporter, and there are many evidences in the correspondence between these two scientists that Gray was willing to challenge Darwin and disagree with some of his conclusions. Nevertheless, Gray saw the importance of Darwin's work and the ways in which it provided answers to the troublesome issues that he had confronted in his own botanical efforts.</p>

<h3>Gray responds to Darwin's theory</h3>

<p>After considerable interchange--one might even say debate--among Gray, Darwin, and Hooker, Gray wrote to Hooker in October 1859 (one month before the publication of <em>On the Origin of Species</em>) saying that he had absolutely no problem with cognate species arising by variation. He did, however, raise a concern that would be the source of much future discussion. He wondered about Darwin's "carry[ing] out this view to its ultimate and legitimate results,--how [do] you connect the philosophy of religion with the philosophy of your science." He added: "I should feel uneasy if I could not connect them into a consistent whole--i.e., fundamental principles of science should not be in conflict."<sup>4</sup></p>

<p>When <em>Origins</em> was published, Gray wrote a clear, positive, yet critical review in <em>The American Journal of Science</em>. Aware of mounting religious opposition, he ended his review by arguing that whereas one could use Darwin's theory in support of an atheistic view of Nature, one could use any scientific theory in that way. He wrote:  "The theory of gravitation and ... the nebular hypothesis assume a <em>universal and ultimate</em> physical cause, from which the effects in nature must necessarily have resulted."<sup>5</sup> He did not see the physicists and astronomers who adopted Newton's theories as atheists or pantheists, though Leibniz earlier had raised such reservations.  And a similar situation existed with the origin of species by natural selection.  Darwin, Gray continued: "merely takes up a particular, proximate cause, or set of such causes, from which, it is argued, the present diversity of species has or may have contingently resulted. The author does not say necessarily resulted."<sup>6</sup></p>

<p>This far Gray could go with Darwin. But there was a point at which he parted company, and that was the fortuitous <em>randomness</em> of the process that Darwin's theory seemed to imply.</p>

        <title>David Lack and Darwin’s Finches</title>
        <link>http://biologos.org/blog/david&#45;lack&#45;and&#45;darwins&#45;finches?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>

        <description>Considering the immense popularity of &quot;Darwin&apos;s finches&quot;, it is quite surprising to learn that Charles Darwin himself had very little to say about them. In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore.</description>
        <content:encoded><![CDATA[<h3>Darwin’s Finches? </h3>

<p>Darwin’s finches are some of the most visible and recognizable symbols of evolution in the world today.  Biology textbooks feature them prominently, and the National Academy of Sciences has enshrined them in the entrance of their headquarters in Washington, DC.  Surely the finches that Darwin collected on the Galápagos islands were a central feature of his evolutionary theory, right?</p>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/Lacks_Finches_NASlobby.jpg" alt="Lobby of the National Academy of Sciences" height="350" width="570"  /></br>Lobby of The National Academies Building.  Courtesy of CPNAS. Photo by Robert Lautman</p>

<p>Actually, the Galápagos finches are never even mentioned in Darwin’s famous work <em>On the Origin of Species</em>.  Nor do they appear in Darwin’s famous notebooks on “Transmutation of Species”, in which he formulated the idea of evolution by natural selection.<sup>1</sup>  Even Darwin’s private diary of his voyage on the HMS <em>Beagle</em> only mentions the Galápagos finches briefly in passing.<sup>2</sup> </p> 

<p>It was only in 1845, in the second edition of <em>The Voyage of the Beagle</em>, that Darwin included a tantalizing sentence about the Galápagos finches:</p>

<blockquote>Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.<sup>3</sup>
</blockquote>

<p>However insightful this statement may have been, Darwin never published anything else about the Galápagos finches for the rest of his life.  Nor did he publically present these birds as direct evidence for this theory of evolution.<sup>4</sup> 
</p>

<p>If these finches were so important to Darwin’s evolutionary theory, why did he remain silent about them?  One of his comments in <em>The Voyage of the Beagle</em> provides us with a clue:</p>

<blockquote>Unfortunately most of the specimens of the finch tribe were mingled together; but I have strong reasons to suspect that some of the species of the subgroup Geospiza are confined to separate islands.<sup>5</sup> </blockquote>

<p>When Darwin was exploring the Galápagos himself in 1835, he had not formulated his theory of evolution yet, and thus he did know what data would be necessary to make definitive conclusions about finch evolution.  In particular, he did not keep careful track of which of his specimens came from which islands.   Moreover, as was customary among naturalists at that time, Darwin only collected a small number specimens—he brought home only 31 finches and 64 total birds from the Galápagos.<sup>6</sup>   </p>

<p>Though Darwin sensed that these birds were truly special, he lacked sufficient evidence to reach any specific conclusions about their evolutionary origins.  It would be up to the rest of the scientific community to carry out the necessary empirical research.  Subsequent expeditions in 1868, 1891, 1897, and 1905 brought back thousands of Galápagos finch specimens, but instead of unlocking the mysteries of evolutionary theory, the Galápagos finches became a great enigma.<sup>7</sup>  </p>

<p>A century after Darwin's voyage, scientists still struggled to explain the staggering variety of finches on this tiny, remote archipelago.  By the mid-1930’s, British Museum ornithologist Percy Lowe argued that the finches presented a "biological problem of first class importance", and he told the British Association for the Advancement of Science that the finches displayed a "bewildering diversity, intergradation, and distribution".<sup>8</sup>   Who would be up to the challenge of making sense of such tremendous biological complexity? It was David Lack.</p>
 
<h3>David Lack</h3>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/David_Lack.png" alt="Ornithologist David Lack" height="291" width="250"  /></br>Ornithologist David Lack</p>

<p>David Lack had an exceptionally keen eye for bird-watching, and he possessed a passion to match it.  By age 15, he had already observed 100 distinct species of birds, and before entering college, authored his first scientific paper.  At Cambridge University in the early 1930’s, Lack was disappointed to find that his zoology professors taught “nothing about evolution, ecology, behavior or genetics, and of course nothing about birds.”<sup>9</sup>  In fact, at that time, there were only two professional ornithologists in all of Britain!</p>

<p>Thus David Lack took it upon himself to create his own learning opportunities.   As an undergraduate, he became the president of the Cambridge Ornithological Club, traveled to Greenland for a bird-watching expedition, and cultivated a relationship with the prominent biologist Julian Huxley (grandson of Thomas Henry Huxley).  Huxley was an inspiring mentor and encouraged Lack to expand his research further by studying tropical birds.<sup>10</sup>  Following this advice, Lack embarked on a research trip to Tanzania in the summer of 1934, but his greatest adventure was yet to come. </p>

<p>In 1937, Lack became fascinated by the scientific mysteries surrounding the Galápagos finches.  But in order to study their behavior, Lack would need to travel to remote islands halfway around the world.   How could he possibly get there?  Once again, Julian Huxley was tremendously supportive and raised funds from two prominent scientific societies to pay for his expedition.  After a long delay, David Lack and five companions finally set off on their journey.</p>

<p>Instead of residing in comfortable quarters aboard a royal naval ship, Lack’s group subsisted on a shoestring budget, traveled on commercial steamers, and stayed with local settlers.  Their experience was definitely not a romantic tale of imperial expedition:</p>

<blockquote>The Galápagos are interesting, but scarcely a residential paradise.  The biological peculiarities are offset by an enervating climate, monotonous scenery, dense thorn scrub, cactus spines, loose sharp lava, food deficiencies, water shortage, black rats, fleas, jiggers, ants, mosquitoes, scorpions, Ecuadorian Indians of doubtful honesty, and dejected, disillusioned European settlers.<sup>11</sup></blockquote>

<p>Whereas Charles Darwin spent only nineteen days on the shores of the Galápagos, Lack and his crew conducted more than five months of meticulous and exhausting study in the harsh climate.  At that time, even the finches themselves provided little solace.  Lack wrote,</p>
	
<blockquote>Darwin’s finches are dull to look at, not only in their orderly ranks in museum trays, but also when they hop about the ground or perch in the trees of the Galápagos, making dull unmusical noises.  Only the variety of their beaks and the number of their species excite attention.<sup>12</sup> <strong></strong></blockquote>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/Lacks_Finches_Cactus_Finch.jpg" alt="Large Cactus Finch–the Galapagos." height="215" width="320"  /></br>Large Cactus Finch on Española Island in the Galápagos Islands</p>

<p>The repetitive tedium requisite for important scientific discoveries is rarely discussed in public, and even today many bright-eyed science students become disillusioned by the painstaking work demanded by their Ph.D. programs.  But one of the things that distinguishes great scientists is their unwavering commitment and tenacity in completing major projects. David Lack's efforts were not in vain: </p>

<p><em>"Despite his personal discomforts (or perhaps because of them), Lack did see something on the Galápagos that no one had ever seen before—natural selection at work among its finches through interspecies competition."</em> <sup>13</sup></p>

<p>When the birds’ breeding season ended in 1939, Lack was ready to return to his home in England.  But the captive finches that he had brought with him fared so badly on the voyage home that he detoured to San Francisco and put them in the care of the California Academy of Sciences.  Turning this mishap into an opportunity, Lack stayed there for five additional months to study the Academy’s enormous  collection of Galápagos finch specimens.<sup>14</sup> </p>

<p>To complete his systematic research, Lack then travelled across the United States to study the Galápagos finch collection housed at the American Museum in New York.<sup>15</sup>   Altogether, Lack examined more than 8000 specimens and specifically measured the length, width, and depth of all their beaks.<sup>16</sup> </p>

<p>Lack’s final obstacle was in getting his research published.  Though he completed his academic manuscript “The Galápagos Finches—A Study in Variation” in 1940, paper shortages during World War II delayed its publication by the California Academy of Sciences until 1945.  Were he only interested in making an original contribution to science, Lack could have stopped here and congratulated himself on a job well-done.  However, his motivation sprung from a deeper source:</p>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/Lacks14finches_sm.jpg" alt="David Lack's illustration of 14 Finches" height="455" width="300" /> </br>David Lack's drawing of 14 species of Galápagos finches, p. 19 of <em>Darwin’s Finches</em></p>

<p><em>"I did not watch birds primarily for scientific reasons but for sheer enjoyment, and from the age of 15 onward returned day after day in a glow of excitement after seeing a new bird or a new habit."</em> <sup>17</sup></p>

<p>Lack’s joyful fascination with the Galápagos finches inspired him to continue developing his conclusions long after returning from his expedition.  While waiting for his academic paper to be published, he began writing a book that would enable students and the general public to share his excitement about these remarkable birds and the evolutionary processes that shaped them.</p>

<p>First published in 1947, Lack’s book became tremendously influential.  Before this time, biology textbooks had never even mentioned the Galápagos finches.  But after David Lack’s study, the finches became a primary example of evolution by natural selection, specifically <a href="http://en.wikipedia.org/wiki/Adaptive_radiation">adaptive radiation</a>.  Not only did textbooks fully rely on Lack’s findings, they also followed his lead in calling them “Darwin’s finches”, the title of Lack’s famous book.<sup>18</sup> </p>

<h3>Iconic Finches</h3>

<p>What was it about these birds that made them such a prominent symbol of evolution?  As Darwin himself pointed out, the numerous Galápagos finch populations each have distinctive beaks, and he speculated that they could have evolved from an ancestral species that came to the islands.  But a complete picture of finch evolution would have to wait another hundred years, when David Lack arrived.</p>

<p>During his five months on the Galápagos, including both the rainy and dry seasons, Lack observed that these beak differences enable the finches to subsist on different kinds of food:</p>

<blockquote>The beak differences between most of the genera and subgenera of Darwin's finches are clearly correlated with differences in feeding methods.  This is well borne out by the heavy, finch-like beak of the seed-eating <em>Geospiza</em>, the long beak of the flower-probing <em>Cactornis</em>, the somewhat parrot-like beak of the leaf, bud, and fruit-eating <em>Platyspiza</em>, the woodpecker-like beak of the woodboring <em>Catcospiza</em>, and the warbler-like beaks of the insect-eating <em>certhidea</em> and <em>Pinaroloxias</em>.<sup>19</sup>  </blockquote>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/finchbeaks_sm.jpg" alt="" height="270" width="350"  /> </br>Lack's image of beak adaptations from <em>Darwin’s Finches</em></p>



<p>Specializing in such different sources of food enables these finches to live in close proximity without directly competing with each other or driving populations to extinction.  The fact that so many of these closely related finches are able to co-exist is a remarkable fact in itself.  As Lack himself put it, “It is not only the origin, but also the persistence, of new species which require explanation.”<sup>20</sup> </p>

<p>But it is also fascinating to consider how these birds got to be so different in the first place.  How did a finch come to have a beak like a “parrot”, “woodpecker”, or “warbler”?  The answer lies in the distinct characteristics of the Galápagos.  Because the islands are so remote, no actual parrots, woodpeckers, or warblers ever settled on it.  In the absence of these species, the Galápagos finches were able to adopt feeding habits and forms that they would never have taken on a large continent full of other birds competing for food.  The isolation of these islands offered just the right conditions for us to see living examples of adaptive radiation.<sup>21</sup> </p>

<h3>Conclusion</h3>

<p>Considering the immense popularity of the Galápagos finches, it is quite surprising to learn that Charles Darwin himself had so little to say about them.  In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore.  By naming his landmark book <em>Darwin’s Finches</em>,<sup>22</sup>  Lack paid homage to the man whose voyage on the HMS Beagle helped transform the study of natural history.  But at the same time, Lack also obscured the fact that evolutionary biology is an enterprise conducted by a large community of brilliant scholars, not just the product of one man’s efforts.</p>

<p>This tendency to immortalize “great men of science” has also led many people to refer to modern evolutionary theory as <em>Darwinism</em>, despite the fact that it has substantially changed and developed over the past 150 years.  It is important to give credit where credit is due, and if that’s the case, we should seriously reconsider how we refer to the Galapagos finches.  Evolutionary biologist Dolph Schluter, who studied the finches several decades after David Lack, had this to say:</p>

<blockquote>I find Lack's intuition really stunning given how little information he had.  He's my hero actually… They should be called Lack's finches.<sup>23</sup></blockquote>

<p class="intro">In the second part of this series, we’ll explore the fact that David Lack, in addition to being a world-renowned evolutionary biologist, was also a devout Christian.  His study of evolutionary theory did not cause him to lose his faith; in fact, he actually <em>converted</em> to Christianity after completing his Galápagos finch research.</p>

<h3>For Discussion</h3>
<strong>We’ve seen in this essay that the term “Darwin’s finches” is misleading, especially since Charles Darwin himself didn’t make the Galapagos finches famous.  Is it also problematic that people refer to modern evolutionary theory as “Darwinism”?  What misunderstandings can arise by associating an entire field of science with just a single person?

        <description>We&apos;ve recently been looking at the evidence for an old earth and the long history and vibrancy of this view among evangelical Christians.  Today’s post features a preview of the updated Question, “How are the ages of the Earth and universe calculated?&quot; revised by Senior Web Consultant and Writer Deborah Haarsma.</description>
        <content:encoded><![CDATA[<h3>How are the ages of the Earth and universe calculated?</h3>

<h4>In a Nutshell</h4>
Many independent measurements have established that the Earth and the universe are billions of years old.  Geologists have found annual layers in glaciers that can be counted back 740,000 years.  Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years.  Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years.  The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old. <br />

<h4>In Detail</h4>

<h3>Introduction</h3>
<p>Astronomers and geologists have determined that the universe and Earth are billions of years old. This conclusion is not based on just one measurement or one calculation, but on many types of evidence.  Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under <a href="#reading">Further Reading</a>. These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years. As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.</p>

<h3>Age of the Earth from seasonal rings and layers</h3>
<p>If you’ve ever seen a horizontal slice of a tree trunk, you’ve seen how a tree forms a new growth ring each year.   In years of drought, the tree grows less quickly so the ring is narrower; in good growing seasons the ring is thicker.  A tree’s age can be found by simply counting its rings.  By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate.   This method can even be used on dead trees that fell in a forest long ago.  For example, the last 200 rings in the dead tree might match up with 200 rings early in the life of the living tree, so the two trees together can count back many years.   In this way, multiple trees can be used to build a master chronology for a forested region.   European oak trees have been used to build a 12,000-year chronology.<sup>1</sup></p>

<p>The annual ice layers in glaciers provide a similar method that goes back much further in history.  Each year, snowfall varies throughout the seasons and an annual layer is formed.  Like the tree rings, this method can be verified by comparison to historical records for weather, as well as to records of volcanic eruptions around the globe that left thin dust layers on the glaciers.   Scientists have drilled ice cores deep into glaciers and found ice that is 123,000 years old in Greenland<sup>2</sup> and 740,000 years old in Antarctica.<sup>3</sup>  These annual layers go back much farther than the 10,000 years advocated by the young earth creationists.  The Earth must be at least 740,000 years old.</p>

<h3>Age of the Earth and solar system from radiometric dating</h3>
<p>In your high school science classroom, you may have seen a large poster of the periodic table hanging on the wall.  The periodic table shows the types of atoms that make up the world around us.  An element in the periodic table can come in different flavors called isotopes.  Some isotopes are unstable, and over time these isotopes “decay” into isotopes of other elements.   For example, Potassium-40 is unstable and decays into Argon-40.   As time passes, a rock will have more and more Argon-40 and less and less Potassium-40.   Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element. The half-life is the time that it takes for half the radioactive sample to change from one element into the other.</p>

<p>Some isotopes have short half-lives of minutes or years, but Potassium-40 has a half-life of 1.3 billion years.  Radiometric dating requires that one understand the initial ratio of the two elements in a given sample by some means.  In this case, Argon-40 is a gas that easily bubbles out and escapes when it is produced in molten rock.  Once the rock hardens, however, all the Argon-40 is trapped in the sample, giving us an accurate record of how much Potassium-40 has decayed since that time.   So, if we find a rock with equal parts Potassium-40 and Argon-40, we know that half the Potassium-40 has decayed into Argon-40, and that the rock hardened 1.3 billion years ago.<sup>4</sup></p>

<p>It’s hard to find rocks on the surface of the Earth that have not been altered over time.  Most old rocks have been eroded by wind and water or submerged by continental plates.   The oldest reliably dated rock formation is in Greenland, where several different isotopes were used to find an age of 3.6 billion years.<sup>5</sup>   Scientists also recently dated zircon grains (which resist erosion) in Western Australia to 4.4 billion years old.<sup>6</sup> To find older rocks that haven’t been eroded, we need to look beyond Earth.  Meteorites are rocks from the solar system that have fallen to Earth recently and haven’t suffered much erosion.  Their pristine interiors give an age that dates back to their formation at the beginning of the solar system.  Nearly all meteorites have the same radiometric age, 4.56 billion years old.<sup>7</sup> Thus, the solar system, including the Earth, is about 4,560,000,000 years old.</p>

        <description>The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity?  Is there actually any theological or religious significance in Higgs physics at all?</description>
        <content:encoded><![CDATA[<p class="date"> The image above describes an "event" (proton-proton collision) recorded in 2012 with the CMS detector at CERN's Large Hadron Collider. According to CERN, "the event shows characteristics expected from the decay of the SM Higgs boson to a pair of Z bosons, one of which subsequently decays to a pair of electrons (green lines and green towers) and the other Z decays to a pair of muons (red lines). The event could also be due to known standard model background processes. ATLAS Experiment © 2012 CERN </p>


<p>Judging from the flurry of headlines over the past week, one might be tempted to think that proof positive of God’s existence (or lack thereof) had just appeared out of a 27-km-tunnel buried beneath the Swiss-French border. This frenzy of news headlines and blog titles hailed the recent news that CERN’s Large Hadron Collider has discovered a brand new particle of a mass of 125-126 GeV, which is assumed to be the Higgs boson, or the so-called “God particle.” The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity?  Is there actually any theological or religious significance in Higgs physics at all?</p>

<p>The short answer is “no,” which becomes apparent when one considers the widely-reported story of how it got named. In 1993, Nobel Laureate physicist Leon Lederman, along with science writer Dick Teresi, wrote a book detailing the history of particle physics starting with Pre-Socratic Greek philosophy Democritus and culminating with the hunt for the Higgs boson. Until this latest discovery, the Higgs boson was the elusive final missing piece of the puzzle known as the Standard Model—a collection of the fundamental particles that constitute our universe and the complex and mathematically-sophisticated relationships between them. Considering how incredibly difficult finding the Higgs boson was proving to be, Lederman wanted to name the book after that “goddamn particle,” according to some of his collaborators. His editor, however, would not allow it and so the name was shortened to “The God Particle: If the Universe Is the Answer, What is the Question?” And thus ‘the God particle’ was born, carrying with it more than enough social baggage for such a miniscule particle.</p>

<img src="http://biologos.org/uploads/static-content/Zosia_Krusberg.jpg" alt="" height="340" width="250" style="float:right;margin:0px 0px 0px 10px;"  />

<p>Particle physicist Dr. Zosia Krusberg (at right) is visiting assistant professor of physics and astronomy at Vassar College and thinks “the term ‘god particle’ is unfortunate. The Higgs boson is no more (or less) divine or spiritually significant than any other elementary particle within the standard model of particle physics.” It may be fundamental to explaining one of the most basic characteristics of the universe—namely the existence of matter and mass in addition to energy—but “it is no more (or less) important than any other physics principle underlying the Standard Model.” </p> 

<p>Last week’s discovery was monumental in that it may have finally provided experimental evidence for the Higgs Mechanism and defined the specific energy of the resulting Higgs boson, but even this “breakthrough” for particle physics leaves many scientific questions unresolved. Finding the Higgs boson completes the Standard Model, but it does not do away with many other questions and shortcomings of the current state of particle physics, such as the constituent particles of dark matter, a quantum theory of gravity, and other “mathematically subtle problems.” Not to mention that there is still significant work to be done to determine the exact nature of this newly-found particle. According to Dr. Krusberg, this particle might behave just as the Standard Model predicts or it could instead be “a Higgs-like particle that will serve as a gateway into explorations of physics beyond the Standard Model." Krusberg continued, “And I guarantee that it is this latter scenario that most of us are hoping for: physicists love nothing more than discovering the shortcomings of their theories, since this is the first step toward more fundamental theories with even more predictive power!”</p>

<p>No, finding the Higgs boson does not answer all the questions of particle physics, much less lend insight into the existence (or not) of God.  For that reason, Dr. Krusberg (like most physicists) bemoans the term ‘God particle’ and insists, “There really is nothing either literally or metaphorically god-like about the Higgs boson.”  Indeed, one writer for the British journal The Guardian reached such a point of frustration about the name that he ran a <a href="http://www.guardian.co.uk/science/blog/2009/jun/05/cern-lhc-god-particle-higgs-boson ">competition for alternatives</a>. The winner was “the champagne flute boson,” ostensibly because the bottom of a champagne bottle is an excellent and oft-used demonstration of the energy potential of the Higgs Mechanism. Or then again, perhaps it is simply because physicists thought that finally finding this shy particle would call for some of the bubbly.</p>

<p>On the other hand, some science writers and scientists can appreciate the ‘educational benefits’ of such a mysterious and controversial name because it attracts the attention of the general public and puts a relatable face on an extremely esoteric physics concept. Krusberg herself admits that “People are naturally drawn to the mysterious and the controversial, providing educators with great teaching opportunities.” But she worries about the larger social implications involved in “mixing the vernacular of physics and spirituality,” not least because such uncritical mixing can lead the non-scientific community to draw conclusions about the authority and reach of science that are not justified.</p>

<p>Understanding that the Higgs boson is not the literal stuff of God and that it does not prove or disprove God’s existence (as the name seems to suggest) extinguishes the fire under any sort of religious outcry. But this does not mean that its discovery is irrelevant to the discussion of science and faith, nor to the Christian community as a whole. As Dr. Krusberg remarks, “The recent discovery of [this] new boson at the LHC perfectly embodies the scientific process at its best (and thereby illustrates to the public why and how science works).” Scientific exploration of nature is not a fool-proof endeavor; healthy skepticism and accountability to a wide community of other researchers are absolutely critical to its success. But such evidence of the power and finesse of well-executed science as we saw last week is a testament to our ability to explore and understand the ‘how’ of the universe. God has equipped humanity with the desire, the intellectual abilities, and the collective will to recognize and explore the cosmic order and beauty of his creation. God has made our home knowable, and has given us the tools and capacities by which to know it.</p>

<p class="date"> At left, Cern researchers present their findings to a few hundred of their colleagues in Melbourne, Australia.  Image © 2012 CERN </p>

<p>It is valuable, then, for the Christian community to understand and appreciate how science works, in part to recognize that there are many instances in which science and the church work in tandem in order to better understand and better serve the world. But I think there is something else we can draw from the story of the Higgs boson, too. The nickname ‘the God particle’ has touched nerves in religious communities because it implies that science has the ability to prove or disprove divine existence by physical means.  Even though the physics community is by no means claiming insight into the divine, it is sometimes assumed by the religious community that scientists view their work as chipping away at God’s existence when they begin to understand something that was previously unknown, or known only “by faith” in esoteric theories and models.</p>

<p>And yet, regardless of motives or metaphysical interpretations, perhaps physicists' search for the Higgs boson <em> is in fact</em> an apt picture of our own search for God.  How many times have we stared up at the starry ceiling in times of crisis and prayed fervently for some kind of sign from God to assure us of his presence? And how many times has that much-desired evidence appeared only in retrospect, when we look back to see God’s hand faithfully and elegantly working in ways inscrutable at the time? It took a <em>community</em> of physicists to discern the presence of the Higgs boson. But even so, they could only do so after the fact from the cascade of particle decays it sparked; they could not observe the particle itself directly. In a similar way, though we often do not see the working of God directly, “in the moment,” we still trust in his presence and providence, often depending on friends, family and the community of the church to help us see his hand in hindsight.  </p>

<p>So while the discovery of the Higgs boson does not itself explain God, we rejoice at the subtle yet striking new insight we have into God’s creative genius via the Higgs boson and at the way God gives evidence of his faithfulness in the ordered creation itself. Perhaps, however, the greatest insight we can glean from this breakthrough is an analogy for the way God calls us to seek him and find him together, in the community of those who follow his son.</p>

        <description>Scientism is a rather strange word, but for reasons that we shall see, a useful one. Though this term has been coined rather recently, it is associated with many other “isms” with long and turbulent histories: materialism, naturalism, reductionism, empiricism, and positivism.</description>
        <content:encoded><![CDATA[<img src="http://biologos.org/uploads/static-content/SaintSimonResized.jpg" alt="" height="224" width="161" style="float:left; margin:0px 10px 0px 0px;"/><p>&nbsp;</p><p>&nbsp;</p>
<blockquote>A scientist, my dear friends, is a man who foresees; it is because science provides the means to predict that it is useful, and the scientists are superior to all other men. --Henri de Saint-Simon<sup>1</sup></blockquote>
<p>&nbsp;</p><p>&nbsp;</p><p>&nbsp;</p>

<p>Scientism is a rather strange word, but for reasons that we shall see, a useful one. Though this term has been coined rather recently, it is associated with many other “isms” with long and turbulent histories: materialism, naturalism, reductionism, empiricism, and positivism. Rather than tangle with each of these concepts separately, we’ll begin with a working definition of scientism and proceed from there.</p>

<p>Historian Richard G. Olson defines scientism as “efforts to extend scientific ideas, methods, practices, and attitudes to matters of human social and political concern.” <sup>2</sup>  But this formulation is so broad as to render it virtually useless. Philosopher Tom Sorell offers a more precise definition: “Scientism is a matter of putting too high a value on natural science in comparison with other branches of learning or culture.” <sup>3</sup>  MIT physicist Ian Hutchinson offers a closely related version, but more extreme: “Science, modeled on the natural sciences, is the only source of real knowledge.” <sup>4</sup>  The latter two definitions are far more precise and will better help us evaluate scientism’s merit.</p>

<h3>A History of Scientism</h3>

<p>The roots of scientism extend as far back as early 17th century Europe, an era that came to be known as the Scientific Revolution. Up to that point, most scholars had been highly deferential to intellectual tradition, largely a combination of Judeo-Christian scripture and ancient Greek philosophy. But a torrent of new learning during the late Renaissance began to challenge the authority of the ancients, and long-established intellectual foundations began to crack. The Englishman Francis Bacon, the Frenchman Rene Descartes, and the Italian Galileo Galilei spearheaded an international movement proclaiming a new foundation for learning, one that involved careful scrutiny of nature instead of analysis of ancient texts.</p>

<img src="http://biologos.org/uploads/static-content/descartesresized.jpg" alt="" height="252" width="204" style="float:right; margin:0px 0px 0px 10px;" /><p>Descartes and Bacon used particularly strong rhetoric to carve out space for their new methods. They claimed that by learning how the physical world worked, we could become “masters and possessors of nature.” <sup>5</sup> In doing so, humans could overcome hunger through innovations in agriculture, eliminate disease through medical research, and dramatically improve overall quality of life through technology and industry. Ultimately, science would save humans from unnecessary suffering and their self-destructive tendencies. And it promised to achieve these goals in this world, not the afterlife. It was a bold, prophetic vision.</p>

<p>As this new method found great success, the specter of scientism began to emerge. Both Bacon and Descartes elevated the use of reason and logic by denigrating other human faculties such as creativity, memory, and imagination. Bacon’s classification of learning demoted poetry and history to second-class status.<sup>6</sup> Descartes’ rendering of the entire universe as a giant machine left little room for the arts or other forms of human expression. In one sense, the rhetoric of these visionaries opened great new vistas for intellectual inquiry. But on the other hand, it proposed a vastly narrower range of which human activities were considered worthwhile.</p>

<h4>The Enlightenment</h4>

<p>A century later, many of the Enlightenment intellectuals continued their love-affair with the power of natural science. They claimed that not only could science enhance the quality of human life, it could even promote moral improvement. The Encyclopedist Denis Diderot aimed to collect, organize, and preserve all human knowledge so that “our children, becoming better instructed, may become at the same time more virtuous and happy.” <sup>7</sup> Many of the French philosophes even claimed that science could be a substitute for religion. In fact, during the French Revolution, numerous Catholic churches were converted into “Temples of Reason” and held quasi-religious services for the worship of science.<sup>8</sup></p>

<h4>Positivism</h4>

<p>The 19th century witnessed the most powerful and enduring formulation of scientism, a system called positivism. Its founder was August Comte, who built his positive philosophy from a deep commitment to David Hume’s empiricism and skepticism. Comte claimed that the only valid data is acquired through the senses. Nothing was transcendent, and nothing metaphysical could have any claim to validity.<sup>9</sup> The task of scientists was twofold—first, to demonstrate how all phenomena, including human behavior, are subject to invariable natural laws.<sup>10</sup> Second, they would reduce these natural laws to the smallest possible number, and ultimately unify them under the laws of physics.<sup>11</sup></p>

<p>Comte also subsumed all of human intellectual history into a single process which he called the Law of Three Stages. In his view, each branch of knowledge passes through three stages: the theological or fictitious, the metaphysical or abstract, and lastly the scientific or positive state. He believed that through the continual advancement of human understanding, religion would fade away, philosophy and the humanities would be transformed into a naturalistic basis, and all human knowledge would eventually become a product of science. Any ideas outside that realm would be pure fantasy or superstition.</p>

<h4>Logical Positivism</h4>

<img src="http://biologos.org/uploads/static-content/ruler2.jpg" alt="" height="188" width="250" style="float:left;margin:0px 10px 0px 0px;" /><p>Positivism did not lose its appeal in the 20th century. To the contrary, a group known collectively as The Vienna Circle reinvigorated the fundamental tenets of positivism with enhanced symbolic logic and semantic theory. They called their approach, fittingly, logical positivism. In this system, there are only two kinds of meaningful statements: analytic statements (including logic and mathematics), and empirical statements, subject to experimental verification. Anything outside of this framework is an empty concept.<sup>12</sup></p>

<p>Given its sweeping claims, logical positivism came under heavy scrutiny. Karl Popper pointed out that few statements in science can actually be completely verified. However, a single observation has the potential to invalidate a hypothesis, and even an entire theory. Therefore, he proposed that instead of experimental verification, the principle of falsifiability should demarcate what qualified as science, and by extension, what can qualify as knowledge.<sup>13</sup></p>

<p>Another weakness of the positivist position is its reliance on a complete distinction between theory and observation. Observations, essential to the empirical approach of science, were claimed by positivists to be brute facts which one could use to establish, evaluate, and compare the theories. However, W.O. Quine pointed out in his “Two Dogmas of Empiricism” that observations themselves are partly shaped by theory (“theory-laden”).<sup>14</sup> What counts as an observation, how to construct an experiment, and what data you think your instruments are collecting—all require an interpretive theoretical framework. This realization does not deal a death-blow to the practice of science (as some post-modernists like to claim), but it does undermine the positivist claim that science rests entirely on facts, and is thus an indisputable foundation for knowledge.</p>

<h3>Scientism of Today</h3>

<p>Scientism today is alive and well, as evidenced by the statements of our celebrity scientists:</p>

<img src="http://biologos.org/uploads/static-content/nasa_resized.jpg" alt="" height="263" width="264" style="float:right;margin:0px 0px 0px 10px;" />
<blockquote>The Cosmos is all that is or ever was or ever will be. –Carl Sagan, Cosmos<br /><br />

The more the universe seems comprehensible, the more it also seems pointless. –Stephen Weinburg, The First Three Minutes<br /><br />

We can be proud as a species because, having discovered that we are alone, we owe the gods very little. –E.O. Wilson, Consilience</blockquote>

<p>While these men are certainly entitled to their personal opinions and the freedom to express them, the fact that they make such bold claims in their popular science literature blurs the line between solid, evidence-based science, and rampant philosophical speculation. Whether one agrees with the sentiments of these scientists or not, the result of these public pronouncements has served to alienate a large segment of American society. And that is a serious problem, since scientific research relies heavily upon public support for its funding, and environmental policy is shaped by lawmakers who listen to their constituents. From a purely pragmatic standpoint, it would be wise to try a different approach.</p>

<p>Physicist Ian Hutchinson offers an insightful metaphor for the current controversies over science:</p>

<blockquote>The health of science is in fact jeopardized by scientism, not promoted by it. At the very least, scientism provokes a defensive, immunological, aggressive response from other intellectual communities, in return for its own arrogance and intellectual bullyism. It taints science itself by association.<sup>15</sup></blockquote>

<p>Noting that most Americans enthusiastically welcome scientific advancements, particularly those in health care, transportation, and communications, Hutchinson suggests that perhaps what the public is rejecting is not actually science itself, but a worldview that closely aligns itself with science—scientism.<sup>16</sup> By disentangling these two concepts, we have a much better chance for enlisting public support for scientific research than we would by trying to convince millions of people to embrace a materialistic, godless universe in which science is our only remaining hope.</p>

<h3>Distinguishing science from scientism</h3>

<p>So if science is distinct from scientism, what is it? Science is an activity that seeks to explore the natural world using well-established, clearly-delineated methods. Given the complexity of the universe, from the very big to very small, from inorganic to organic, there is a vast array of scientific disciplines, each with its own specific techniques. The number of different specializations is constantly increasing, leading to more questions and areas of exploration than ever before. Science expands our understanding, rather than limiting it.</p>

<img src="http://biologos.org/uploads/static-content/Gears_large.jpg" alt="" height="340" width="250" style="float:left;margin:0px 10px 0px 0px;" /><p>Scientism, on the other hand, is a speculative worldview about the ultimate reality of the universe and its meaning. Despite the fact that there are millions of species on our planet, scientism focuses an inordinate amount of its attention on human behavior and beliefs. Rather than working within carefully constructed boundaries and methodologies established by researchers, it broadly generalizes entire fields of academic expertise and dismisses many of them as inferior. With scientism, you will regularly hear explanations that rely on words like “merely”, “only”, “simply”, or “nothing more than”. Scientism restricts human inquiry.</p>

<p>It is one thing to celebrate science for its achievements and remarkable ability to explain a wide variety of phenomena in the natural world. But to claim there is nothing knowable outside the scope of science would be similar to a successful fisherman saying that whatever he can't catch in his nets does not exist.<sup>17</sup> Once you accept that science is the only source of human knowledge, you have adopted a philosophical position (scientism) that cannot be verified, or falsified, by science itself. It is, in a word, unscientific.</p>

        <content:encoded><![CDATA[<p>Today we have a chance to witness a special moment in history as Venus transits across the disk of the Sun for people across the world to see.  This rare astronomical occurrence may have been witnessed by Montezuma in 1520, was first predicted by Johannes Kepler in 1631, launched Captain James Cook’s expedition around the world in 1768, helped us determine the Earth's distance from the Sun in the 1882, and will not occur again until 2117. </p>

<p>The astronomy community is particularly interested in this event because <a href="http://en.wikipedia.org/wiki/Exoplanet">exoplanets</a> throughout the Milky Way galaxy regularly transit their parent stars in just the same way. This local example will allow astronomers to test and refine techniques used to determine the composition of these exoplanets' atmospheres, providing insight into whether these distant planets could possibly harbor life. </p>

<p>As Venus begins to cross in front of the disk of the Sun, Venus's atmosphere will refract the Sun's light, illuminating the backlit portion of the planet's atmosphere. Telescopes on the ground and in orbit will be trained on this thin arc of atmosphere lit up by the Sun. Astronomers will use spectrometers to break the light up into its constituent colors, from which they can determine the chemical composition of our over-heated sister planet's atmosphere. Once perfected, this same technique can be used to examine the atmospheres of planets far beyond our own solar system, offering us one of our best clues as to the habitability of these distant worlds.</p>

<p>Not only is this process of discovery exciting for natural science, but it has profound theological ramifications as well.  Surely a God capable of orchestrating both the majestic swirls of a spiral galaxy and the intricate language of DNA could bring forth life where and when He chooses, but only now are we on the verge of being able to answer the age-old question: “Did God confine His creative life-giving actions to our own planet, or does His abundant fertility extent far beyond our limited experience?” </p>

<p>In 1882, William Harkness, the Director of the U.S. Naval Observatory, was one of two astronomers to determine from the transit of Venus the distance from Earth to the Sun. Just as previous viewers could never have imagined calibrating the scale of the solar system from such an event, Harkness could not predict its importance in 2004 and 2012 (the most recent Venus transits).  As we look to the future, we can hardly imagine what new frontiers the next Venus transit of 2117 will find us exploring.</p>

<div class="see-also">"We are now on the eve of the second transit of a pair, after which there will be no other till the twenty-first century of our era has dawned upon the earth, and the June flowers are blooming in 2004. . . . What will be the state of science when the next transit season arrives God only knows. Not even our children's children will live to take part in the astronomy of that day. As for ourselves, we have to do with the present ..." ~William Harkness, the Director of the U.S. Naval Observatory, quoted in 1882 (source: NASA.gov)</div>

<p class="intro">The image above shows Venus on the eastern limb of the Sun during the 2004 transit.  As described in Tucker's essay, the faint ring around the planet comes from the scattering of light through its atmosphere, which allows some sunlight to show around the edge of the otherwise dark planetary disk. The faint glow on the disk is an effect of the TRACE telescope through which the image was captured. For more on the historical significance of the transits of Venus (including the voyage of Captain James Cook), see this <a href="http://science.nasa.gov/science-news/science-at-nasa/2012/02jun_jamescook/">article</a> from NASA, which also includes links to several live webcasts of today's transit.</p><br>

        <description>In this five part series, two young men, Josh and Aron, engage each other through e&#45;mail letters. Their conversation oscillates between the seemingly suspicious elements of God and the gospel (raised by Josh) as well as responses that offer meaningful insight into these questions (answered by Aron). Ideas such as prayer, judgment, and the concealed nature of God are among the many points in this truth&#45;seeking exchange.</description>
        <content:encoded><![CDATA[<p class="intro"> Recently, we became aware of an email conversation between two young persons: one a young physicist and a deeply committed Christian named Aron and the other, Josh, a person who at least at the time the conversation began was a skeptic. The exchange is so rich that we’ve asked for permission to post it here. We hope you find it as informative and intriguing as we have.</p>

<h3>Josh wrote:</h3>

<p>Hi Aron,</p>
<p>Thanks for taking the time to discuss this. I am still skeptical. Please consider the following:</p>
<p>Suppose:</p>
<ol><li>The evangelical Christian God exists, is omnipotent, omniscient, loves people and wants them to believe in him so that they can join him in heaven.</li>
<li>There are sincere truth-seeking people who have not seen evidence that convinces them that this God exists, but if they just saw Jesus walk on water, feed thousands with a few fish and loaves, rise from the dead, have vivid and non-contradictory dreams about heaven, etc, they would believe. It does not have to be one single awesome event. It can be many different signs to different people. If God employed a multitude of miracles and awesome ways to reach people, people will not idolize one single manifestation. They would understand that these diverse awesome signs are just different ways that God is using to show his presence and not God himself.</li>
<li>God has no other agenda more important than the agenda of loving people and having people believe in him that would prevent him from showing evidence like the ones above.</li></ol>

<p>Then, I believe God would show himself more clearly to these people, but he isn't doing so, so one of the above statements must be false.</p>

<p>The first step in communicating yourself is to signal your presence. 'Creation' may or may not convincingly point to the existence of a Creator, but I don't see how it points to the Christian Creator and not some unknown Creator that is not the Christian God. To many people, the Bible is just a religious book, and not special compared to other religious books of other religions. Just because it is claimed to be true and to have had its accuracy preserved doesn't mean that claim is true. A non-believer who requires more substantial evidence in order to be convinced should not be required to just accept the Bible, because he has no prior reason to believe in it.</p>

<p>In essence, God is letting these people go to Hell because they fail to believe as a result of his failure to provide convincing evidence. In this situation, humility doesn't really matter.</p>

<h3>Aron wrote:</h3>

<p>Dear Josh,</p>

<p>In my last email, I was discussing only of this life, and what reasons God might have for partially concealing himself for the sake of our spiritual development here. The issue you raise in this email regards the final judgement and Hell. Any discussion of this must necessarily be more tentative than discussions of life on earth, because the final judgement hasn't happened yet, so we don't know right now exactly what it will be like. If the life of Jesus reveals what God is like, then God is very merciful (even though he is also very severe towards hypocrisy and unforgiveness). If Christianity is true, then Jesus will be the one doing the judging. If he was merciful when he was on earth, then he will also be merciful when he comes again.</p>

<p>Your objection to Christianity is this: How could a loving God possibly arrange things so that a sincere truth-seeking nonchristian, (an atheist, polytheist etc.) goes to Hell through no fault of his own?</p>

<p>In order to check to see if this is a problem, we should first check to see whether there are any sincere truth-seeking non-Christians who go to Hell. One could imagine two different kinds: 1) people who have never been exposed to Christianity, and therefore have no opportunity to know it is true, and 2) people who have been exposed to Christianity but claim there is not enough evidence to believe it.</p>

<p>With respect to the people in the category (1), how do you know that the Christian God would send them to Hell just for not being Christians? I think the Bible teaches quite explicitly that God does NOT do this. In Acts 17, Paul is trying to convince the Athenians not to worship idols. He says, "In the past God winked at this ignorance, but now he commands all people everywhere to repent." In other words, Paul explicitly says that God did not hold the idol worship of the pagans against them before they had an opportunity to hear the gospel and repent. Furthermore, it says in the book of Revelation that people are redeemed from every "nation, tribe, people, and language". Since many groups went extinct before having an opportunity to hear the gospel, it is clear that at least some people are saved without having explicitly heard the gospel in their lifetimes. Finally, Peter seems to suggest that there is some opportunity for people to believe the gospel even after they have died, when he says:</p>

<blockquote><p>"For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit. After being made alive, he went and made proclamation to the imprisoned spirits—to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built....the gospel was preached even to those who are dead, so that they might be judged according to human standards in regard to the body, but live according to God in regard to the spirit." (1 Peter 3:18-20 and 4:5-6).</p></blockquote>

<p>This text goes against the standard evangelical view that there is no chance to be saved after death. On the other hand, evangelicals also say you're supposed to go with the Bible rather than what any particular church says, so I think I'll go with the Bible. :-)</p>

<p>Now let's turn to category (2), the case of a person who has been exposed to Christianity but doesn't believe it because they claim not to have enough evidence. I think there are several different possible things that might be going on here:</p>

<p>First of all, just because they claim to be seeking the truth doesn't mean they really are:</p>

<p>(A) They might actually have enough evidence to believe in God, but dishonestly refuse to admit it to themselves, because they don't want it to be true. In this case, they are not actually sincere, and have rejected God not because of inadequacy of the evidence, but because of stubborn rebellion. In this case, there is no reason to think that they would accept God even if they did have more evidence. So it is not God's fault that they do not believe. It should be pointed out that many of the people who saw Christ multiply the loaves, heal people, raise the dead etc. nevertheless refused to believe. It is naive to think that if everyone saw miracles, everyone would believe. Rather the people who don't want to believe become more firm in their rejection of God.</p>

<p>(B) Or, although they don't have enough evidence to believe, they choose not to investigate to see whether it is true or not. In this case, it is their own fault that they don't have enough evidence. If people claim to base their decisions on evidence and reason, it is hypocritical if they reject Christianity without carefully considering whether there is sufficient evidence for Christ's Resurrection and other miracles to show that Christianity is true. In particular, it is utterly irrational to insist on seeing a miracle personally in order to believe if there is lots of evidence that other people have seen miracles. People don't refuse to believe in scientific results unless they personally witness the experiments, so long as multiple reliable people say they have done the experiments, that is enough. Why should religion be different?</p>

<p>I never assume that anybody is intellectually dishonest until I have some specific reason to think they are dishonest. But I've talked to enough atheists to know that most of them do fall into categories (A) or (B), at least to some extent. However, I'm sure that there do exist cases in which atheists are sincere. In this case:</p>

<p>(C) It might be that although right now they do not have enough evidence to believe, later God will give them enough evidence to believe and they will become Christians. This might happen either before or after death, for all we know.</p>

<p>(D) Or, although they will die without explicitly believing in Jesus, it may be that through caring for the needy, Jesus will regard them as having accepted him without knowing it. (See Matt 25:31-36)</p>

<p>(E) Or, although they do not have enough evidence to believe, they live wicked lives without love. Since God is love, this means that what little they do know about God, they hate (even though they do not know it is God that they are hating). If people hate God, there is no reason to think they will stop hating God if God reveals himself more clearly. Why should God reveal himself to someone who would not benefit from it?</p>

<p>Given all of the possibilities A-E, it is not at all obvious that there ARE any sincere, truth-seeking atheists who are going to Hell. I think that most of them aren't really sincere or truth-seeking, and also that many of them aren't going to go to Hell.</p>

<p>Jesus says "Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or the age to come." In other words, when people reject Jesus without knowing his divinity, God forgives them and does not hold it against them. But when someone by the influence of the Spirit receives the insight necessary to understand that God is working through Jesus, and then rejects him, this is a sin that cannot be forgiven. (God forgives everyone if they repent, but the point is that people who persist in this attitude won't repent.)</p>

<p>It should also be made explicit that no one <em>deserves</em> to go to heaven; God saves people by his mercy. But God will not overrule people who insist at every opportunity that they want nothing to do with his mercy. If people would hate God if they knew him, God is being merciful by not revealing himself to them yet. It gives them a chance to grow and develop, so that maybe later they would be prepared to accept him.</p>]]></content:encoded>

        <content:encoded><![CDATA[<p align="center"><iframe src="http://player.vimeo.com/video/33680427?title=0&amp;byline=0&amp;portrait=0" width="571" height="321" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe></p>

<p class="intro">Today's video is courtesy of filmmaker Ryan Pettey, director/editor of Satellite Pictures and features physicist Ard Louis.</p>

<p>In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris. Gould believed (and wrote in his book <em>Wonderful Life</em>) that if the "tape" of evolution were rerun, the chance that anything like human intelligence would emerge is essentially zero. In other words, humanity is here through random accident. Gould pointed to the work of Morris and fellow scientists in their research of the Burgess Shale as evidence for this view.</p>

<p>However, Morris himself disagrees, pointing to what is called evolutionary convergence. As Morris notes, there are numerous examples of identical features evolving multiple times throughout the history of life independently. Morris believes that if the tape of life were replayed, we would see something like humans emerge. A Christian might say, it looks like we were planned.</p>


<p>Some Christians might find Simon Conway Morris' viewpoint, with its implicit teleology, more attractive. Others, perhaps motivated by a high view of providence, may find Gould's emphasis on contingency equally congenial to their faith.  What do you think?</p>]]></content:encoded>

<p>As we noted in <a href="http://biologos.org/blog/biologos-and-the-june-2011-christianity-today-cover-story">our response</a> to the June article in <em>Christianity Today</em> “The Search for the Historical Adam,” the evidence for gradual creation is overwhelming, with more studies supporting the evolutionary process being published each year. We’ve looked at many of these evidences: from fossils, from comparative anatomy, from genetics. Today, we’d like to highlight for our readers a compelling video from the annual TED Conference featuring geneticist Svante Pääbo. You may remember Pääbo from his efforts to extract and sequence DNA from 30,000(+) year old Neanderthal bones (we mentioned his work <a href="http://biologos.org/blog/a-geneticists-journey">here</a>).</p>

<p>In this eighteen minute video, Pääbo covers a lot of ground, noting several lines of genetic evidence for the evolution of modern humans from earlier hominids in Africa, as well as for the interbreeding between early humans and Neanderthals. We’ve covered some of this data before, but it’s particularly compelling to hear it described by one of the scientists leading the field of study.</p>

<p>However, our goal at The BioLogos Foundation isn’t just to make the Church aware of the fascinating and convincing scientific evidence for gradual creation. As we have said <a href="http://biologos.org/blog/a-geneticists-journey">before</a>:</p>

<blockquote><p>BioLogos exists to help Christians think carefully about the ramifications of these new data in light of long-standing traditional ways of viewing human creation. We have some re-thinking to do, but it can be done and will be done within the context of a Christian faith that is fully orthodox and thoroughly evangelical. Any time we draw closer to truth, to God’s truth, we have nothing to fear. There is still much to learn, but we can look back at what we have learned with awe—absolute awe.</p></blockquote>

<p>It is truly amazing that we know so much now about our early days.  For example, Africans do not have DNA which is specifically derived from Neanderthals, whereas people in the rest of the world do carry a small amount.  This confirms the picture of human history derived from studying fossils.  Neanderthal bones have not been found in Africa, so it isn’t surprising that their DNA is not there either.  The fact that non-Africans have some of the DNA found in Neanderthal bones confirms that which geneticists knew from other studies: we have two distinct groups of human ancestors—those who left Africa in ancient times and those who stayed.</p>

<p>God chose to reveal himself and to begin working with a distinct sub-group of ancient  humans, those descended from Abraham and Sarah.   To Abraham, God made a marvelous promise.   Drawing his attention to the stars above, God said that someday Abraham’s descendents would outnumber the countable stars in the universe.  And so it came to be.  Indeed through our adoption into the family, we are all children of Abraham.  The God of Abraham is our God too and each one of us is one of those stars too numerous for Abraham to count.</p>

<p>Sometimes, it seems that we are uncomfortable with the notion that God made us through a gradual process that included apes in our family tree.  It is almost as though we would prefer dirt to apes.  Perhaps, in at least some cases, this is due to an inadequate appreciation for the fact that God loves, really loves, all of creation, not just us.  As special as we know we are, we can’t read Psalm 104, Genesis 1, Genesis 9 (where the covenant is not just with Noah but with all living creatures), or Job 38-41 without being reminded that <em>all</em> living creatures are God’s creation (see <a href="http://biologos.org/blog/creation-which-creation">here</a>).  The Neanderthals, the Denisovans, <em>Homo erectus</em>, and the australopithecines were God’s creation too!  Still, we modern humans have been singled out.  We’ve been <em>called</em> out.</p>

<p>True our family tree, as Pääbo shows here, is intriguing.  But let us never forget, that the most important thing about this tree is that God is the vine which exists at its core, and we are called to be the branches which bear fruit.  The fact that many of us have a small amount of Neanderthal DNA, some of us have Denisovan DNA, and others have neither is interesting, but it is really just a side issue for people of faith.  As a result of God’s visit to Abraham, followed eventually by God’s taking on flesh in the person of  Jesus of Nazareth, we can all know God as our heavenly Father.  We are children of God and as such, we are God’s representatives.  We are called to image God.  We are called to love God.  And we are called to love each other and to deeply respect all that he has made.</p>]]></content:encoded>

<p>In a recent interview with the Sirius XM radio show <em>Centered</em>, Karl Giberson, co-author of BioLogos' <em>The Language of Science and Faith</em>, sat down with host Don Belanus to discuss the book and the interplay between science and faith. Among the topics they cover are what constitute the "genuine questions" of science and faith mentioned in the title and whether the age of the earth should be a top priority for pastors to discuss with their congregations.</p>]]></content:encoded>

<p>In this video, author and pastor Brian McLaren discusses the idea of surrogate arguments, in which a debate over one thing is really a means for arguing something completely different. According to McClaren, the argument over the age of the earth is one such example, in which an apparent scientific debate is actually a discussion over the nature of religious authority and how previous generations have understood how we should interpret the Bible. Such debates can lead to two crises: one of confidence and one of ethics. While some have the confidence to differ with the views of the generation that raised them in the faith, McLaren points out that some are not able to overcome the ethical challenge of differing with grace and love. When this happens, he notes, the end result is damage to the Church and a retrenching of the views of the older generation. Managing the crises well requires courage of convictions while also respecting tradition and maintaining a gracious spirit.  Anything less, is not only unwise, it is also unfaithful.</p>]]></content:encoded>

        <title>God&apos;s Use of Time</title>

        <description>I find that when many Christians think about the way God created our universe, they often bring a static expectation similar to what we bring to an ordinary statue. It’s as if we assume the physical realm were merely a rigid three&#45;dimensional sculpture, immovable with time.</description>
        <content:encoded><![CDATA[<p>I can still recall the first time I encountered a man performing as a living statue.  His costume, body paint, and utter stillness made him very convincing.  I also recall the eerie feeling I experienced upon first seeing him move. Ordinary statues are, of course, static, but if you hang around a living statue long enough you’re bound to see it move, if only to blink its eyes.  I find that when many Christians think about the way God created our universe, our planet, and the forms of life that dwell on it, they often bring a static expectation similar to what we bring to an ordinary statue.  It’s as if we assume the physical realm were merely a rigid three-dimensional sculpture, immovable with time.</p>

<p>But since time exists, change and development are possible.  The sciences have acquired the tools to “look back” in time and explore our universe’s rich history, so we know that the universe and the life in it do indeed evolve. Through these observations in the natural realm, it’s difficult to avoid the conclusion that God typically prefers to do His work gradually rather than instantaneously.  In what follows, I’d like to briefly explore some of the ways that our universe has been and is evolving over long periods of time and attempt to show that the concept of a God who makes use of long timescales ought to be familiar to us from the story of redemption in scripture.  And like observing a living statue, by staring long enough (in this case millions and billions of years) we are able to see a world that is moving and changing, which hopefully deepens our appreciation for the wonder of God’s dynamic creative acts.</p>

<h3>God’s use of time in the physical realm</h3>

<p>The sense of enjoyment that comes from studying the dynamically evolving universe that God has created is similar to that of a gardener when he or she watches a seed grow into a mature plant.  And when considering the history of the cosmos, the analogy of a seed in a garden is an apt one, with each branch of science reinforcing and corroborating the story that is told.</p>

<p>From physics we learn that all the matter and energy that now exists in our universe originated in a hot, dense state (something akin to a primordial seed) which burst forth and has been expanding and cooling ever since.  Myriads of stars have gone through the process of forming, burning, and dying, with many exploding in what's called a supernova.  These long stellar life cycles have been going on for billions of years and are responsible for "cooking up" and dispersing all the atomic elements necessary for forming planets like Earth and creatures like us.</p>

<p>Once our planet formed, we know from geology and its theory of plate tectonics that the earth's crust has been in a constant (but very slow) process of moving and changing, shifting even the continents around over many millions of years and forming majestic mountains, islands, and other geological features.  The picture becomes even more fascinating when biology enters the landscape, describing how life has slowly developed, also over many millions of years, beginning from the simplest of organisms and progressing all the way to beings like us, of such complexity that we are able to reflect on and enjoy the entire display.</p>

<p>But how do we know all this, since our short lives don’t allow us to see these long drawn out processes in action? I see these same sciences as a great gift from God that allow us to explore beyond the bounds of our own time.  For instance, when astrophysicists look up into the night sky, they see light that has taken millions or even billions of years to reach us, meaning that they are literally looking at what our universe looked like in the distant past.  Geologists look back in time by studying layers of rock, sediment, or ice. They have even found evidence that the earth's magnetic field has flipped many times over the course of the Earth's history so that even the direction our trusty compasses point isn’t constant!  Biologists have the fossil record and genetics as a means of exploring the rich and fascinating history of life, teaching us about the ancestors of modern humans as well as exotic creatures such as dinosaurs.  All around us the physical world is shifting, changing, and unfolding in an extraordinary way, teaching us that God, the ultimate Gardener, is pleased to watch his creation grow and mature gradually.</p>

<h3>God's use of time in redemption up to Jesus</h3>

<p>A good number of Christians find the idea of God using long maturation times in creation threatening to their understanding of scripture.  But what we learn about God from scripture is not inconsistent with a God who works over long timescales.  We see this if we look at the grand meta-narrative of the entire Bible, of which I’ll cover a few highlights to demonstrate my point.</p>

<p>After humans made a mess of their intended role in the created order, God desired to restore it and put it right.  And like what we learn from the sciences about the evolution of the universe, He decided to take his time about it.  God began his redeeming work with a promise to use Abraham's family to be a blessing to the entire world (Gen. 12:1).  This was a promise that was ultimately fulfilled in Jesus nearly two millennia later.  Now if God had been in a hurry, he might simply have allowed Sarah to conceive by the Holy Spirit and bring forth Jesus directly.  But instead, he decided to take the scenic route, working through Abraham’s seed, including Jacob, Moses, David, and others until the time was right for Jesus.</p>

<p>As time went on and God’s people developed into a nation, David rose to the throne and God made another promise -- that of perpetual kingship to David’s line (2 Sam 7:13).  This was another opportune time for Jesus to be born, take the throne, and fulfill the promise.  But again we find God taking his time, allowing the kingdom to be divided and eventually conquered, and God’s people sent into a long exile, until the time was right for Jesus, nearly a millennium after David.</p>

<h3>God's use of time in redemption after Jesus</h3>

<p>The Christian faith holds that in the “fullness of time” (Gal. 4:4) God sent Jesus as the individual in whom all the promises of God ultimately converged.  Just as God's physical creation developed slowly and eventually brought forth our earth and life and humanity, so God's purposes slowly unfold and culminate in Jesus, the descendant of Abraham and David who becomes the blessing to the world.</p> 

<p>But here again is another case that demonstrates the point I’m attempting to make.  Even the blessing that Jesus comes to announce and inaugurate develops slowly and dynamically – God, the Gardener, continues to slowly cultivate. Jesus himself teaches us to expect this to be the case in parables about the kingdom such as that of the mustard seed (Mark 4:30-32).  Thus, the world isn’t automatically cured of its ills after Jesus’ resurrection.  Both then and now, evil, sin, and injustice still exist and there is much that remains to be redeemed. The church is called to continue living in this meta-narrative until we reach the second climax: when Jesus reappears and ushers in the fullness of the new heavens and new earth.</p>

<p>A similar point can be made about God’s redemptive work in the lives of individual Christians as well.  God forms each of his children over time through our relationships, our experiences, the trials we encounter, and the service we render.  “I am the vine, you are the branches”, says Jesus in John 15:5.  God is “growing us” as individuals and as every Christian knows from experience, the maturing process often seems very long indeed.</p>

<p>In conclusion, this brief survey has shown a consistent picture of how God works in his creation. In the cosmos, in the evolution of life, in the redemption of the world, and in the redemption of individuals, God sees fit to use long timescales for accomplishing his purposes. Moreover, with the similarities between what we learn of God from nature and from scripture, Christians needn’t react defensively to what science tells us about the history of the cosmos.  Instead, we can indulge in the opportunity to marvel at the ever continuing work of God the Gardener, both in His dynamic creation and His dynamic acts of redemption.</p>

        <description>Giberson&apos;s essay makes the case that scientific fundamentalists are not merely arguing for the supremacy of science but also presenting science as a quasi&#45;religious replacement. The agenda of the &quot;New Atheists&quot; is not merely to refute mainstream religion but to replace it. Unfortunately, the scientific community is poorly represented by these aggressive public figures.</description>
