The important thing is not that the unconscious determines neurosis- of that one Freud can quite happily, like Pontius Pilot, wash his hands. Sooner or later, something would have been found, humeral determinate, for example- for Freud, it would be quite immaterial. For what the unconscious does it to show us the gap through which neurosis recreates a harmony with a real- a real that may not be determined.
