Which C.S. Lewis work was published in 1943 as a critique of education and moral relativism?

The Abolition of Man was published in 1943 as a critique of education and moral relativism.

The book grew from three lectures Lewis delivered at the University of Durham in February 1943. In the lectures, he challenged an approach to education that treated moral responses as merely subjective feelings. Lewis argued instead for the importance of objective value and natural law.

The work consists of three chapters: “Men Without Chests,” “The Way,” and “The Abolition of Man.” Its final chapter warns that attempts to conquer nature through technology could ultimately place humanity under the control of a small group of technocrats.

The book is not a novel and does not present Narnia’s mythology. The Discarded Image is Lewis’s study of the medieval and Renaissance worldview, while Studies in Words examines changes in meaning across language and literature.
