 In contrast, in the 1970s and since a number of researchers, often influenced by Mary McIntosh or Michel Foucault, argued that class relations, the human sciences, and other historically constructed forces create sexual categories and the personal identities associated with them. For advocates of this view, such as David Halperin, how sex is organized in a given cultural and historical setting is irreducibly particular (Halperin, 2002). The emphasis on the social creation of sexual experience and expression led to the labeling of the viewpoint as social constructionism, although more recently several of its proponents have preferred the term ‘historicism.’ Thus homosexuality, as a specific sexual construction, is best understood as a solely modern, Western concept and role. Prior to the development of this construction, persons were not really ‘homosexual’ even when they were only attracted to persons of the same sex. The differences between, say, ancient Greece, with its emphasis on pederasty, role in the sex act, and social status, and the contemporary Western role of ‘gay’ or ‘homosexual’ are simply too great to collapse into one category.
