Whether the interpretations made by social scientists of the thoughts, utterances and actions of other people, including those from an alien culture or a different period in history, are objectively correct, whether the forms of explanation they employ conform to those of the natural sciences, and whether values have a role in arriving at the theory that delivers the interpretations, are the main questions addressed by the contributors to this volume. Of particular importance in the discussion of the issues are developments in the philosophy of language and mind. The eight essays converge on the themes of intentionality, realism and theory choice, reflecting the amount of attention being given to these matters when this book was first published in 1980. Together they make a distinguished contribution to discussion in the area and serve to underline the importance of intellectual collaboration on such discussion between philosophy and the social sciences.
