“We have to consider that a man who has been under such enormous mental pressure for such a long time is naturally in some danger after his liberation, especially since the pressure was released quite suddenly. This danger (in the sense of psychological hygiene) is the psychological counterpart of the bends. Just as the physical health of the caisson worker would be endangered if he left his diver's chamber suddenly (where he is under enormous atmospheric pressure), so the man who has suddenly been liberated from mental pressure can suffer damage to his moral and spiritual health.”
