Which C.S. Lewis book presents the Abolition of Man lectures?

The C.S. Lewis book presenting the Abolition of Man lectures is The Abolition of Man.

Lewis delivered the lectures at the University of Durham in February 1943, and they were published as a book later that year. The work examines education, moral judgment, and the danger of treating values as merely subjective feelings.

The book argues for what Lewis called the Tao, a term he used for a broad set of traditional moral principles found across cultures. He warned that abandoning objective moral norms could undermine the very human qualities that make rational and ethical life possible.

The Abolition of Man is not a science-fiction novel, despite its title. It is a short philosophical and educational critique. Lewis’s concerns about technological power and the reshaping of human nature have made the book influential in debates about science, education, and ethics.
