What was the title of C.S. Lewis’s 1943 book about the education of the imagination and moral judgment?

C.S. Lewis’s 1943 book about education and moral judgment is The Abolition of Man.

The Abolition of Man developed from three lectures Lewis gave at the University of Durham in 1943. He criticized an approach to education that, in his view, treated value judgments as merely subjective emotions. The book argues that moral education should cultivate both reason and properly trained feeling.

Lewis defended what he called the Tao, a term he used for a cross-cultural body of basic moral principles. He cited traditions from China, India, ancient Greece, Rome, Judaism, Christianity, and other sources to argue that many civilizations recognize comparable duties and virtues.

The final section warns that technological power without an objective moral framework could allow human beings to reshape humanity itself. The title does not mean that people will literally vanish. It refers to the possible loss of human nature and moral agency through the rejection of objective value.
