Ethics, Persuasion and Truth

by J. J. C. Smart

Published 1 November 1984

Originally published in 1984, deals with meta-ethics – that is the semantics and pragmatics of ethical language. This book eschews the notions of meaning and analyticity on which meta-ethics normally depends. It discusses questions of free will and responsibility and the relations between ethics on the one hand and science and metaphysics on the other. The author regards ethics as concerned with deciding what to do and with persuading others – not with exploring a supposed realm of ethical fact.


Originally published in 1963. In an introductory chapter the author argues that philosophy ought to be more than the art of clarifying thought and that it should concern itself with outlining a scientifically plausible world view. Early chapters deal with phenomenalism and the reality of theoretical entities, and with the relation between the physical and biological sciences. Free will, issues of time and space and man's place in nature are covered in later chapters.
