No, Object #2

The Law is drawn up actually as a dis-alienation device where the subject reaches for the Real and cannot reach its object, so the perverse need to be told "no" arises (I'm paraphrasing Zizek in that "know not" book, 265). The breaker for this is the choice between le père ou le pire (Lacan's pun), the fatherly Law or the worst possibility: desire's impasse, the inattainability of the object (Zizek's page 267).
