What phrase titles C.S. Lewis’s 1943 lecture criticizing modern education and moral subjectivism?

The Abolition of Man is the title of C.S. Lewis’s 1943 lecture series criticizing modern education and moral subjectivism.

The work began as three lectures delivered at the University of Durham in February 1943. Lewis argued that education should not merely train students to express preferences or manipulate nature; it should cultivate appropriate responses to objective value.

Its three chapters are titled “Men Without Chests,” “The Way,” and “The Abolition of Man.” Lewis uses these arguments to warn that technological power without moral formation could ultimately diminish humanity rather than perfect it.

The book is often grouped with Lewis’s Christian apologetics, but its argument also engages philosophy, education, and ethics. It is not the same work as Mere Christianity, The Problem of Pain, or Miracles, even though all are major nonfiction books by Lewis.
