G. E. Moore

What is Principia Ethica about?

Principia Ethica (1903) is G. E. Moore's groundbreaking work of moral philosophy that became one of the most influential philosophical texts of the twentieth century. Moore argues that "good" is a simple, unanalyzable quality—attempts to define it in terms of pleasure, evolution, or any natural property commit what he calls the "naturalistic fallacy." He concludes that the greatest goods in life are the pleasures of personal affection and aesthetic appreciation. The book revolutionized academic ethics and profoundly influenced the Bloomsbury Group, whose members adopted Moore's values as a guide for living.
