What was the title of C.S. Lewis’s 1943 book about Christian morality and education?

C.S. Lewis’s 1943 book about Christian morality and education is The Abolition of Man.

The book developed from three lectures Lewis delivered at the University of Durham in February 1943. It examines moral education, argues for the existence of objective value, and criticizes approaches that reduce moral judgments to personal emotion or subjective preference.

Lewis organized the work into three chapters: “Men Without Chests,” “The Way,” and “The Abolition of Man.” He used the term Tao to describe a cross-cultural framework of traditional moral principles, while warning that attempts to reshape humanity through purely technological control could undermine human nature.

The title can be misleading if read as a story about literal extinction. Lewis was instead discussing the possible loss of qualities he considered distinctly human, including reason, moral judgment, and the capacity to value. The work is a philosophical essay rather than one of his fictional novels.
