One of the greatest thinkers of the twentieth century, C. S. Lewis was a scholar at Oxford University for three decades and then a professor of Medieval and Renaissance literature at Cambridge University until the end of his career. An atheist throughout his early life, he converted to Christianity in 1931. He is not generally known as a political or economic commentator and usually avoided partisan commitments. Yet, in spite of his indifference to politics as such, he did often give prescient analysis of a variety of political topics.
