Julie ou la Nouvelle Heloise (Jean-Jacques Rousseau)
As the chapter title indicates, this section views particular romantic/sexual desires and orientations as reflecting or being motivated by trends of fashion. That is: the ways in which desire (both emotional and physical) were expressed--although not necessarily how they were experienced--were a reflection of what a particular culture at a particular time considered to be “normal”. “Normal” in the sense of expected and understandable, not necessarily in terms of normative behavior and condoned activities.
Lanser examines the conjunction of the novel as a genre with "modernity" as defined in this work and considers its relationship to sapphic themes, despite the superficially overwhelming heteronormativity of the genre. One hallmark of the novel is the way in which it explores the contradictory imperatives of self-determination and socialization. The focus of the novel on the formation of couples and the subjective nature of desire opens the conversation--as previously seen with political and social conversations--to the inclusion or exclusion of sapphic subjects under that rubric.
