C.S. Lewis and the Search for Rational Religion

John Beversluis's monograph presents a critical examination of C.S. Lewis's philosophical arguments for Christianity, challenging the widespread perception of Lewis as a rigorous rational defender of theistic belief. The work systematically analyzes Lewis's major apologetic writings, including Mere Christianity, The Problem of Pain, and Miracles, subjecting his arguments to careful philosophical scrutiny.

Beversluis contends that Lewis's reputation as a formidable Christian apologist rests on philosophically weak foundations. The author identifies numerous logical fallacies, false dilemmas, and instances of special pleading throughout Lewis's corpus. Of particular concern is Lewis's trilemma argument regarding Jesus's divinity, which Beversluis demonstrates relies on an artificially restricted set of options. Similarly, the book exposes significant problems in Lewis's moral argument for God's existence, showing how Lewis conflates different senses of moral obligation and makes unwarranted leaps from moral experience to metaphysical conclusions.

The monograph situates Lewis within the context of 20th-century British philosophy, noting his distance from professional philosophical discourse and his tendency to rely on outdated philosophical frameworks. Beversluis argues that Lewis often misrepresents opposing positions, particularly naturalism and moral subjectivism, creating strawman arguments that appear compelling only because they fail to engage with sophisticated versions of these views.

Significantly, Beversluis examines Lewis's response to the problem of evil, finding his theodicy philosophically inadequate and emotionally unsatisfying. The author demonstrates how Lewis's arguments shift between incompatible positions and fail to address the logical tensions between divine omnipotence, omniscience, and benevolence in the face of gratuitous suffering.

The work's importance lies in its systematic deconstruction of arguments that have influenced millions of readers. Beversluis challenges not only Lewis's conclusions but also the intellectual culture that has uncritically embraced his apologetics. By applying rigorous philosophical analysis to popular religious arguments, the monograph contributes to broader discussions about the standards of rational discourse in religious debate.

While acknowledging Lewis's literary talents and personal sincerity, Beversluis ultimately concludes that Lewis's project of establishing Christianity on rational grounds fails. The monograph serves as a corrective to hagiographic treatments of Lewis and raises important questions about the relationship between rhetorical persuasiveness and philosophical validity in religious apologetics.
