What was the title of C.S. Lewis’s 1943 book arguing against cultural relativism?

The Abolition of Man is C.S. Lewis’s 1943 book arguing against cultural relativism.

The work developed from three lectures Lewis delivered at Durham University in February 1943. It examines education, moral judgment, and the danger of treating values as merely subjective emotional reactions. Lewis argues for an objective moral order, which he calls the Tao.

The book is not a novel and is not primarily a general biography of humanity. Its three chapters are titled “Men Without Chests,” “The Way,” and “The Abolition of Man.” Lewis uses these sections to criticize an educational approach that, in his view, separates feeling from reason and moral formation.

The title can mislead modern readers into expecting a discussion focused mainly on technology or physical extinction. Lewis’s central concern is the possibility that humanity could be reduced by rejecting objective value. The book remains a major text in debates about education, ethics, and natural law.
