ABSTRACT
The aim of theory in empirical science is to develop analytical schemes of the empirical world with which the given science is concerned. This is done by conceiving the world abstractly, that is, in terms of classes of objects and of relations between such classes. Theoretical schemes are essentially proposals as to the nature of such classes and of their relations where this nature is problematic or unknown. Such proposals become guides to investigation to see whether they or their implications are true. Social theory is conspicuously defective in its guidance of research inquiry. It is rarely couched in such form as to facilitate or allow directed investigation to see whether it or its implications are true. Representative terms like mores, social institutions, attitudes, social class, value, cultural norm, personality, reference group, social structure, primary group, social process, social system, urbanization, accommodation, differential discrimination and social control do not discriminate cleanly their empirical instances.
