The Abolition of Man C. S. Lewis

Lewis criticizes modern attempts to debunk natural values, such as those that would deny objective value to the waterfall, on rational grounds. He says that there is a set of objective values that have been shared, with minor differences, by every culture, which he refers to as "the traditional moralities of East and West, the Christian, the Pagan, and the Jew...". Lewis calls that the Tao, from the Taoist word for the ultimate "way" or "path" of reality and human conduct. (Although Lewis saw natural law as supernatural in origin, as evidenced by his use of it as a proof of theism in Mere Christianity, his argument in the book does not rest on theism.)

Without the Tao, no value judgments can be made at all, and modern attempts to do away with some parts of traditional morality for some "rational" reason always proceed by arbitrarily selecting one part of the Tao and using it as grounds to debunk the others.

The final chapter describes the ultimate consequences of this debunking: a not-so distant future in which the values and morals of the majority are controlled by a small group who rule by a perfect understanding of psychology, and who in turn, being able to see through any system of morality that might induce them to act in a certain way, are ruled only by their own unreflected whims. In surrendering rational reflection on their own motivations, the controllers will no longer be recognizably human, the controlled will be robot-like, and the Abolition of Man will have been completed.

An appendix to The Abolition of Man lists a number of basic values seen by Lewis as parts of the Tao, supported by quotations from different cultures.

A fictional treatment of the dystopian project to carry out the Abolition of Man is a theme of Lewis's novel That Hideous Strength.

Passages from The Abolition of Man are included in William Bennett's 1993 book The Book of Virtues.
