What is the title of C.S. Lewis's 1943 philosophical book about education and moral values?

The Abolition of Man is C.S. Lewis’s 1943 philosophical book about education, morality, and objective values. It began as a series of lectures delivered at the University of Durham in 1943 and was published later that year.

Lewis argues that moral judgments cannot be reduced entirely to subjective feelings or personal preference. He presents a cross-cultural moral order, which he calls the Tao, as a framework of basic values recognized in different civilizations.

The book criticizes educational approaches that, in Lewis’s view, train students to distrust value judgments while still relying on inherited moral assumptions. Its final section imagines how attempts to control nature may ultimately transform human beings themselves.

The title does not refer to the abolition of humanity through a single political event. It describes Lewis’s concern that technological power and moral relativism could diminish the qualities that make people fully human.
