“From a scientific point of view, therefore, we are forced to consider Hitler, the Fuehrer, not as a personal devil, wicked as his actions and philosophy may be, but as the expression of a state of mind existing in millions of people, not only in Germany but, to a smaller degree, in all civilized countries. To remove Hitler may be a necessary first step, but it would not be the cure. It would be analogous to curing an ulcer without treating the underlying disease. If similar eruptions are to be prevented in the future, we cannot content ourselves with simply removing the overt manifestations of the disease. On the contrary, we must ferret out and seek to correct the underlying factors which produced the unwelcome phenomenon. We must discover the psychological streams which nourish this destructive state of mind in order that we may divert them into channels which will permit a further evolution of our form of civilization.”— American OSS psychological profile of Hitler.”
