Freud in his work The Neuro-psychoses of defense introduces an account about the defense of psychosis. In this account Freud claims that the defense comprises the ego rejecting ideas it does not like and going on to behave as if it never had the ideas in the first place. As Freud states, “… [here is] a kind of defense. Here, the ego rejects the incompatible idea together with its affect and behaves as if the idea had never occurred to the ego at all.” It will be shown that this idea is taken up by Lacan and is expressed in his idea about foreclosure. Freud goes on to say in the same article that when the ego rejects the incompatible idea it, in effect, detaches itself in part, or wholly from reality. Freud states this clearly when he says, “…the ego breaks away from the incompatible idea, but the latter is inseparably connected with a piece of reality, so that, in so far as the ego achieves this result, it, too, has detached itself wholly or in part from reality.”
