Series: John Polkinghorne on Natural Theology
Polkinghorne discusses the origins and aims of natural theology in this series. It does not offer truth, but rather a “best explanation” for the world, answering primarily meta-questions. Two such questions asked by Polkinghorne are, “Why is science possible at all?” and “What makes the universe so special?” To explore the answers, he looks at the ability of human minds to penetrate mysteries of the natural world as well as the fine-tuning of the universe necessary to produce the fruitfulness of life.
Caution! Design Arguments Ahead
Design arguments have been around forever and expressed in various ways. Most of them fall into what we call natural theology, which is the process of inferring something about the existence and nature of God by the inspection of nature.
Fine-tuning and the “Fruitful Universe”
I ask the question, “Why is the universe so special?” Now scientists don’t like things to be special; we like things to be general, and our natural anticipation would have been that the universe is just a common specimen of what a universe might be like.
What is the "fine-tuning" of the universe, and how does it serve as a "pointer to God"?
Fine-tuning refers to the surprising precision of nature’s physical constants, and the beginning state of the Universe. To explain the present state of the universe, even the best scientific theories require that the physical constants of nature and the beginning state of the Universe have extremely precise values.
