In the Discourse of the Hysteric, $ stands in the place of the agent, S1 in the place of the other, a in the place of truth, and S2 in the place of the product (Seminar 20 Encore 16). The barred subject (representing the unconscious of the subject) acts as its cause, because the Hysteric begins her discourse from the question of castration (Seminar 17 112). Her unconscious desire dominates her speech. Surplus jouissance is in the place of truth in her discourse, not only because of her pleasure in knowing but also because her subjectivity articulates the cost of entry into the Symbolic order (Seminar 17 37). The Discourse of the Hysteric produces S2 because she speaks of the loss inherent to subjectivity. For Lacan, the Discourse of the Hysteric articulates the ‘truth’ of the Master’s Discourse: namely, that it is founded on the operation of castration and that its effect is the unconscious. For this reason, Lacan argues that the Discourse of the Hysteric opens the way for the Discourse of the Analyst. (Seminar 20 41) 52
