It has been argued with increasing frequency in recent years that the vocabulary of social science is to a large extent an action vocabulary and that any attempt to systematize concepts and establish bases for understanding in the field cannot, therefore, succeed unless it is firmly built on action theory. I think that these claims are sub stantially correct, but at the same time it seems to me that action theory, as it is relevant to social science, still awaits vital contributions from logic and philosophy. For example, it has often been said, rightly I believe, that situa tions in which two or more agents interact constitute the subject-matter of social science.
