What was the title of C.S. Lewis’s 1943 book arguing against modern education’s effects on values?

The Abolition of Man is C.S. Lewis’s 1943 book about education, moral values, and human nature.

The work began as three lectures delivered at the University of Durham in 1943. Lewis criticized educational approaches that, in his view, treated moral judgments as merely subjective emotional reactions. He argued instead for an objective moral order, which he called the Tao in the book’s comparative discussion.

The three chapters are titled “Men Without Chests,” “The Way,” and “The Abolition of Man.” Lewis connected the loss of objective value with the possibility that technological power could eventually reshape or diminish humanity itself.

The book is sometimes mistaken for The Discarded Image, Lewis’s study of the medieval and Renaissance worldview, or for The Personal Heresy, a work co-written with E.M.W. Tillyard. The Abolition of Man is a short philosophical critique, not a novel and not a general history of education.
