In this volume, originally published in 1928, Mackenzie explores the meaning of Value and its place and relation in human thought and life. Divided into two parts, the first concerns itself with more general problems concerning Value while the latter part details the bearing Value has upon social problems. Mackenzie integrates the major branches of philosophy (Logic, Ethics, Metaphysics and Aesthetics) to analyse and evaluate the fundamental problems of citizenship making this title ideal for students of Philosophy and Politics.
