Theoretical Concepts and Inductive Inference

Abstract

This work represents an attempt to clarify the role which theoretical concepts may play within inductive scientific inference or inductive systematization. A study is made of some of the possible gains that accrue from the introduction of theories employing new theoretical concepts. We are especially interested in gains for which theoretical concepts are logically indispensable, as they provide us with strong methodological reasons for the introduction and employment of theoretical concepts. We have restricted ourselves to dealing with relatively simple kinds of theories, which may be taken to exemplify theories from the primarily non-quantitative sciences.
