While covering much of the same timeframe, Cadden takes a broader and more diverse view than Laqueur, while acknowledging the reality of his two models (the one-sex and two-sex models). In all eras, the “facts” about sex and sexuality are filtered through cultural prejudices. Medieval ideas about sex difference were part of the culture’s assumptions about gender. Medieval society was not a single culture, and the era covered several overall shifts in thinking, so there isn’t a single unified “medieval idea” of sex difference that can be pointed to.
