Abstract

A welcome reprint of a classical study in the theory of value first published in 1958. This, a comprehensive empirical study of values, culminates in the pivotal concept of selective system that "first came to light in the description of the purposive act." A descriptive definition of a selective system is offered after a detailed and painstaking examination of sources of value. "A selective system is a structural process by which a unitary dynamic agency is channeled in such a way that it generates particular acts, dispositions, or objects, and also activates a specific selective agency by which some of the trials are rejected and others are incorporated into the dynamic operation of the system." Selective systems are viewed as natural norms. The ethical import of selective systems is argued in Ethics published in 1960. In terms of Pepper's development of a world hypothesis, The Sources of Value occupies a unique place in his philosophical enterprise. In Concept and Quality, a sequel to World Hypotheses and a discussion and formulation of a new world hypothesis called "Selectivism," the whole analysis in The Sources of Value provides the root metaphor.--A.
