C. S. Lewis (1898-1963) was a Belfast-born English literary critic, novelist, and Christian apologist. The popularity and simplicity of Lewis's philosophical apologetics belie the intellectual depth of his work. His Mere Christianity is probably the most successful work of Christian apologetics of the twentieth century, and his Narnia books are beloved by children and adults for their wonderful blend of charm, fantasy, and theological insight.
Lewis grappled with the problem of evil in The Problem of Pain and with supernaturalism in Miracles. The Abolition of Man focuses on the importance of emotion and objective moral truths to our understanding of human nature.1
