Book excerpt: This book allows us to accompany C. S. Lewis on his intellectual and spiritual journey from atheism to pantheism and eventually to Christianity. It analyzes key elements of Lewis's Christian worldview and identifies challenges leveled against it from alternative worldviews. It examines Lewis's apologetic methodology, highlighting how it was shaped by his worldview, and provides an analysis of Lewis's specific responses to a number of objections. The project also serves as a comparative analysis of worldviews, particularly as they relate to truth claims of the Christian faith. The notion of worldview is critical to the formulation of views. One's worldview determines how reality is perceived. It's characterized as a set of glasses through which we view our surroundings and interpret experiences. It accounts for the perspective we bring to every event in life and helps explain why different people "see" things differently when looking at the same data. The same evidence may lead one person to reject a particular conclusion, while moving another to embrace what the other rejected. Lewis's major works are explored at length in this book. Although much has been written about Lewis, Hofer's examination of the influence of worldview on his work is unique.
