If virginity is at the heart of Southern values, then growing up and exploring sexual identities becomes a pretty difficult business – at least, it is for the Compsons. Tangled in the sense of right and wrong promoted by the older generation, the Compson children have to fight their way out of oppressive (and even impossible) circumstances. Sex is the undiscussed heart of the novel – if only because Caddy, the runaway daughter, throws all social and sexual mores to the wind. Struggling to overcome the devastation of Caddy’s loss, her brothers find it impossible to discover their own sexuality outside of their relationship(s) to their sister.
The Sound and the Fury is a meditation on the ways that Southern morality interferes with developing a sexual identity.
Quentin Compson’s sexual identity is a reflected one: he only experiences his own sexuality via that of his sister, Caddy.
