" Any obstruction of the natural processes of development... or getting stuck on a level unsuited to one's age; takes its revenge, if not immediately, then later on the onset of the second half of life, in the form of serious crises, nervous breakdowns, and all manner of physical and psychic sufferings. Mostly they are accompanied by vague feelings of guilt, by tormenting pangs of conscience, often not understood, in face of which the individual is helpless. He knows he is not guilty of any bad deed, he has not given way to an illicit impulse, and yet he is plagued by uncertainty, discontent, despair, and above all by anxiety - a constant, indefinable anxiety. And in truth he must usually be pronounced "guilty". His guilt does not lie in the fact that he has a neurosis, but in the fact that, knowing he has one, he does nothing to set about curing it. "
