Abstract
This paper defends the claim that social scientists who are interested in the study of institutions should not conduct fights about the meaning of the terms "institution", "organization" and the other terms that are used in the theory of institutions. They should instead concentrate on constructing theories in order to explain the phenomena they are interested in. Defining the terms that one wants to use is a legitimate part of the theoretical endeavor, but it is by no means as important as most institutional theorists tend to think. The paper argues in favor of this claim by drawing on a relevant discussion in the philosophy of science which deals with the role of definitions in the process of constructing a theoretical system.
