Which 1943 C.S. Lewis book argues against reducing education to instinct and emotion?

The Abolition of Man is the 1943 C.S. Lewis book that argues against reducing education to instinct and emotion.

The book developed from three lectures Lewis delivered at the University of Durham in February 1943. In its first section, “Men Without Chests,” he criticizes an approach to education that treats value judgments as merely subjective responses. He argues that reason and emotion should work together rather than being separated.

Lewis presents what he calls the Tao, a term he uses for a cross-cultural body of objective moral principles. In the final section, he warns that attempts to conquer nature through technology can ultimately become attempts by some humans to control others. The work is philosophical and cultural criticism, not a conventional novel.

The Abolition of Man is sometimes confused with The Problem of Pain, Lewis's 1940 book on suffering, or with Miracles, published in 1947. Its distinctive concern is moral education, objective value, and the consequences of technological power.
