What is the title of C.S. Lewis’s 1944 book defending objective moral values?

The Abolition of Man is C.S. Lewis’s 1944 book defending objective moral values. It developed from three lectures Lewis delivered at the University of Durham in February 1943, known collectively as the Riddell Memorial Lectures.

Lewis criticized an approach to education that treated value judgments as merely subjective emotional reactions. He argued that traditions across cultures recognize a shared moral order, which he called the Tao. In his argument, rejecting such standards threatens the foundations of humane education and society.

The book is a philosophical and educational work rather than a novel. Its title refers to the possibility that attempts to control nature through technology could ultimately diminish human agency and character. It is often discussed alongside Lewis’s essays on education and natural law.
