C. S. Lewis published The Abolition of Man in 1944 in the midst of World War II. We can perhaps imagine the ominous and suggestive nature of this timing. But, as readers soon discovered, the book was not at all about the War, or Hitler’s eugenics, or the looming nuclear threat. Lewis’s real subject is the soul and its education. According to Lewis, the real enemy—more dangerous than any nation, weapon, or science—is a philosophy: nihilism. It is perhaps a bit misleading to say that nihilism is a “post-modern” philosophy, for there have been nihilists and advocates of nihilism as long as there have been men. But it is true that this philosophy has come to be more widely preached and practiced in our time than ever before. In The Abolition of Man Lewis both explains and combats this modern (post-modern) development.
