A reprint of the popular 1969, Prentice-Hall edition, the principal innovation of this philosophical introduction to value theory is its focus upon values as they are dealt with in everyday life situations, and have sometimes been studied by sociologists and social psychologists, rather than upon value as has been standard in the philosophical tradition. The treatment of values is developed in the light of relevant work in the social sciences, particularly economics. The result is a book suitable as a textbook for upper-class and graduate courses in the theory of values and as supplementary material for both courses in normative ethics and foundations-oriented courses in economic theory.

With this first of eight volumes, the eminent economist Fritz Machlup launches his monumental inquiry into the production of knowledge as an economic activity. Volume I presents the conceptual framework for this inquiry and falls into three parts: Types of Knowledge, Qualities of Knowledge, and Knowledge as a Product. Originally published in 1981. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
