<p>John Stuart Mill (1806–73) was the most influential English philosopher of the nineteenth century. His vast intellectual output covered a range of subjects — traditional philosophy and logic, economics, political science — and included this work, a founding document in the area now known as social science.<br> In The Logic of the Moral Sciences, Mill applied his considerable talents to examining how the study of human behavior, society, and history could be established on a rational, philosophical basis. The philosopher maintains that casual empiricism and direct experiment are not applicable to the study of complex social phenomena. Instead, "empirical laws, " drawn from historical generalizations, must be derivable from a deductive science of human nature. Mills' insights and approaches have remained relevant in the century and a half since this treatise's publication. This volume will prove of vital interest to historians of philosophy and the social sciences as well as to undergraduate social science majors.<br></p>
