What is the title of C.S. Lewis's 1943 book about education, morality, and modern society?

C.S. Lewis's 1943 book about education, morality, and modern society is The Abolition of Man.

The Abolition of Man began as three lectures delivered at the University of Durham in February 1943. Lewis published the lectures as a short book later that year. He argues that moral judgments are not merely expressions of personal feeling and defends what he calls the Tao, a set of shared moral principles found across cultures.

The book criticizes an approach to education that treats value statements as subjective responses. Lewis then considers how attempts to control nature through technology could ultimately reduce human freedom and moral agency.

The title does not describe the physical extinction of humanity. It refers to the possible transformation of people into beings whose desires and values are controlled by other humans. The Abolition of Man is therefore a philosophical work, not one of Lewis's fictional stories.
