The Everyday Apologetics of C. S. Lewis

This monograph examines C. S. Lewis's distinctive approach to Christian apologetics, analyzing how his arguments function as an integrated defense of theistic belief. McKaughan explores Lewis's method of addressing ordinary doubts through accessible reasoning that combines philosophical argumentation with literary imagination. The work demonstrates how Lewis developed a comprehensive apologetic strategy that speaks to both intellectual objections and existential concerns about God's existence and nature.

McKaughan identifies several key features of Lewis's apologetic method. First, Lewis grounds his arguments in common human experiences rather than technical philosophical discourse, making complex theological concepts accessible to general audiences. Second, he employs imaginative literature alongside rational argumentation, using fiction and metaphor to illuminate spiritual truths that pure logic might fail to convey. Third, Lewis addresses the whole person rather than merely intellectual objections, recognizing that barriers to theistic belief often involve moral, emotional, and imaginative dimensions beyond purely rational concerns.

The study examines Lewis's major apologetic arguments, including his moral argument for God's existence, his critique of naturalism, and his defense of miracles. McKaughan shows how Lewis responds to mid-20th century skepticism by reframing traditional theistic arguments in contemporary terms. Particularly significant is Lewis's argument from reason, which contends that naturalistic materialism undermines the reliability of human reasoning itself, thereby creating a self-defeating position. The work also analyzes Lewis's approach to the problem of evil, demonstrating how he combines logical analysis with pastoral sensitivity.

McKaughan situates Lewis within the broader tradition of Christian apologetics while highlighting his unique contributions. Unlike purely academic apologists, Lewis writes for educated laypeople struggling with doubt. Unlike purely populist defenders of faith, he engages seriously with philosophical objections. This middle position allows Lewis to bridge the gap between scholarly theology and lived religious experience.

The monograph's significance lies in its systematic analysis of Lewis's apologetic method as a coherent intellectual project. McKaughan demonstrates that Lewis's various works constitute a unified defense of Christian theism that remains influential in contemporary discussions. By explicating Lewis's integration of reason, imagination, and experience, the study illuminates an important model for how theistic thinkers can engage modern skepticism while maintaining intellectual rigor and existential relevance.
