This in-depth series by Michael L. Peterson surveys author and apologist C.S. Lewis, reflecting on his arguments for the existence of God as well as his views on Intelligent Design and evolution. Peterson first explains the classical lines of rationale and then discusses Lewis’ Transcendent Intelligence argument. He clearly distinguishes Lewis’ view, however, from other design arguments. As he concludes, he relates Lewis’ thoughts on the firmly grounded theory of evolution, presenting his grand Trinitarian worldview which included this scientific view of the universe.
