On the railroad tracks:
— the discourse of the master says: “the railroad tracks are parallel”
— the discourse of the hysterical says: “I see tracks are converging toward a common point”
— the discourse of the university says: “the tracks are parallel and converge in a projective point”
— the discourse of the analyst says: “the subject is structured as a projective space”
