Following the earlier post on overidentification, a reader has drawn my attention to this passage from Lacan's The Psychoses:
"Don't we analysts know that the normal subject is essentially someone who is placed in the position of not taking the greater part of his internal discourse seriously? Observe the number of things in normal subjects, including yourselves, that it's truly your fundamental occupation not to take seriously. The principal difference between you and the insane is perhaps nothing other than this. And this is why for many, even without their acknowledging it, the insane embody what we would be lead to if we began to take things seriously. So let us, without too great a fear, take our subject [Schreber] seriously."
