You can see the issue in a current debate in psychoanalysis. One version of psychoanalysis will say that the definition of mental health would be the capacity to tell a coherent narrative. From another psychoanalytic point of view, that would be precisely the problem. I think both things are true. People who have suffered ruptured, violated lives need and want some narrative coherence, but narrative coherence quickly can be a problem when it becomes a refuge from thinking. I agree that the idealization of narrative coherence is a bizarre cultural development. The problem is finding forms of incoherence that are listenable to. Psychoanalysis has tried this with the idea of free association—it can create a context in which incoherence is potentially the best way of talking to somebody.
