To corrupt young Eugenie and destroy all her beliefs about virtue and religion through philosophy — is your task as a teacher-libertine.

Eugenie's education is her initiation into enjoyment of her body as a practice of language. Because whole, the work of the bedroom schoolmasters is primarily to enter into language, into knowledge, and into desire: philosophy is taught in the bedroom, and exposition takes place in the midst of an orgy.
