 (7) Philosophers and historians of sex are roughly divided into social constructionists and essentialists. Weak social constructionism claims that the concepts of “homosexuality”, “heterosexuality”, “natural sexuality”, and similar concepts are limited to a specific time period and geographical region. This version is weak because it is only concerned with how sexuality is conceptualized: there might have been homosexuals in ancient Greece, but the ancient Greeks did not think about them using the concept “homosexual”. Strong social constructionism—more in line with Michel Foucault’s views (1976)—claims that the very existence of homosexual and heterosexual orientations is geographically and temporally limited; our concepts of “homosexual” and “heterosexual” do not refer to anything when used to refer to other times and regions. Essentialists claim that homosexuals, heterosexuals, and bisexuals have existed in various times and cultures (see Card 1995: ch. 3; Corvino 1997: pt. III; Corvino 2006b; De Cecco 1981; Mohr 1992: ch. 7; Stein 1992, 1999: ch. 4; Wilkerson 2013).
