Which 1943 C.S. Lewis book argues against reducing education to mere subjective feeling?

The Abolition of Man is the 1943 C.S. Lewis book that argues against reducing education to mere subjective feeling. It developed from three lectures Lewis delivered at the University of Durham in February 1943.

The book responds to ideas about language, value, and education that Lewis believed could undermine objective judgments of good and bad. He argues that human beings should be trained to recognize and respond to objective values, a shared moral order he calls the Tao.

The work is often read as a critique of moral relativism and of educational approaches that treat value statements as nothing more than personal emotion. It is not a novel, and it differs in purpose from Lewis’s apologetic works such as Mere Christianity. Its compact three-part structure—“Men Without Chests,” “The Abolition of Man,” and “We Have No ‘Right to Happiness’”—has made it especially influential in discussions of education and ethics.
