First published in 1903, this volume revolutionized philosophy and forever altered the direction of ethical studies. A philosopher's philosopher, G. E. Moore was the idol of the Bloomsbury group, and Lytton Strachey declared that Principia Ethica marked the rebirth of the Age of Reason. This work clarifies some of moral philosophy's most common confusions and redefines the science's terminology. Moore's focus on conceptual analysis as a method of achieving clarity made him a founder of the current philosophical trend toward analytic and linguistic elements. His simplicity of style and precise use of everyday language exercised an enormous influence on the development of analytic philosophy, and they contribute to the continuing resonance of his compelling arguments.
