Abstract

The aim of this book is both to develop a logic of microreduction, primarily for dynamic theories, or theories that state and explain the attributes and behavior, rather than the evolutionary development, of the things in some domain and, also, to argue that a program of microreduction offers the best hope for the unification of science. After two initial chapters, developing the necessary logical tools and techniques, Causey gets to the central problem of microreduction. The fundamental idea is: a theory, T2, involving entities and attributes proper to some domain, D2, is microreduced to a theory, T1, involving entities and attributes proper to some other domain, D1, when the entities of D2 are explained as structured wholes made up of elements of D1. Attributes present more of a problem. One must first select the classifying attributes which divide the entities of each domain into disjoint equivalence classes. The connecting sentences, relating attributes of D2 to attributes of D1 cannot be identity statements in a set-theoretic formulation but should be such in a more flexible formulation. On this basis, the author gives a detailed specification of the condition for a successful, i.e., no emergence, reduction of the ontology and laws of T2 to those of T1. The second half of the book is more programmatic defending the program of microreduction as the best, though presently unrealizable, means of unifying science. The objections to the program brought by Fodor and others are countered. Though the author’s detailed analysis is geared to the reduction of chemistry to physics, he believes that the same general method should also handle the reduction of social sciences to a science of individual behavior.
