Ethics by J.L. Mackie

Inventing Right and Wrong

This book argues that moral judgments, though commonly treated as reports about objective values, are systematically mistaken because there are no mind-independent moral properties; it develops the argument from cultural diversity and the argument from queerness to show the metaphysical and epistemological implausibility of objective values, defends a form of moral error theory, and examines the consequences for moral language and practice while considering how moral discourse might nonetheless be retained for its social and motivational functions.
