Some years ago a collection of historical and philosophical essays on sex was advertised under the slogan: Philosophers are interested in sex again. Since that time the history of sexuality has become an almost unexceptionable topic, occasioning as many books and articles as anyone would ever care to read. Yet there are still fundamental conceptual problems that get passed over imperceptibly when this topic is discussed, passed over, at least in part, because they seem so basic or obvious that it (...) would be time badly spent to worry too much about them. However, without backtracking toweard this set of problems, one will quite literally not know what one is writing the history of when one writes a history of sexuality.An excellent example of some of the most sophisticated current writing in this field can be found in Western Sexuality, a collection of essays that resulted from a seminar conducted by Philippe Ariès at the Ecole des Hautes Etudes en Sciences Sociales in 1979-80.1 As one would expect, Western Sexuality is characterized by a diversity of methodological and historiographical approaches—social history, intellectual history, cultural history , historical sociology, the analysis of literary texts, and that distinctive kind of history practiced by Michel Foucault and also in evidence in the short essay by Paul Veyne. One perspective virtually absent from this collection is the history of science, and since I believe that the history of science has a decisive and irreducible contribution to make to the history of sexuality, it is not accident that I am going to focus on that connection. But the history of sexuality is also an area in which one’s historiography or implicit epistemology will stamp, virtually irrevocably, one’s first-order historical writing. It is an arena in which philosophical and historical concerns inevitably run into one another. 1.
