Seventy-five years after the publication of C. S. Lewis’s The Abolition of Man (1943), proponents of materialism and naturalism still dominate the public square. Their reductionist and nihilistic approach to morality and other things that give meaning to human life also continues to shape what our children are taught in school. There’s every reason, in face of this ongoing dominance, to defend the case that Lewis’s potent little book sketched three quarters of a century ago—a case I seek to reassert in my primer on moral realism, The Tao of Right and Wrong.
