What is the title of C.S. Lewis’s 1943 book based on his Riddell Memorial Lectures?

The Abolition of Man is C.S. Lewis’s 1943 book based on his Riddell Memorial Lectures.

Lewis delivered the lectures at the University of Durham in February 1943 and published them as a short book later that year. The work criticizes an approach to education that, in his view, treats value judgments as merely subjective emotional responses. He argues for an objective moral order, which he calls the Tao.

The title does not refer to the physical extinction of humanity in a science-fiction plot. It describes Lewis’s warning that attempts to reshape human nature through unrestrained technological power could undermine the qualities that make people human. The book is often read alongside Mere Christianity and Miracles, but its focus is especially philosophical: education, moral reasoning, and the relationship between human power and objective value.
