 The third and final problem for the gay liberationist approach was that it often took this category of ‘identity’ itself as unproblematic and unhistorical. Such a view, however, largely because of arguments developed within poststructuralism, seemed increasingly untenable. The key figure in the attack upon identity as ahistorical is Michel Foucault. In a series of works he set out to analyze the history of sexuality from ancient Greece to the modern era (1980, 1985, 1986). Although the project was tragically cut short by his death in 1984, from complications arising from AIDS, Foucault articulated how profoundly understandings of sexuality can vary across time and space, and his arguments have proven very influential in gay and lesbian theorizing in general, and queer theory in particular (Spargo, 1999; Stychin, 2005).
