C. S. Lewis was an adamant atheist when he entered Oxford University as a student in 1917. By 1931, he was an Oxford don and a Christian. Lewis was someone who did not think highly of climates of opinion, and in his book The Problem of Pain he warned against uncritically going along with them: 'I take a very low view of 'climates of opinion'. In his own subject every man knows that all discoveries are made and all errors corrected by those who ignore the 'climate of opinion'.' A climate of opinion exists today that either intentionally or unintentionally disenchants or debunks C. S. Lewis. In this Element, the author explains Lewis' belief in the existence of the soul and how it related to his conviction that happiness consists of experiences of pleasure and is the purpose of life, God exists, and Christianity is true.
