Carl Jung from “The Undiscovered Self (Present and Future” – 1957:
“What will become of our civilization, and of man himself, if … spiritual and moral darkness of State absolutism should spread over Europe?
We have no reason to take this threat lightly. Everywhere in the West there are subversive minorities who, sheltered by our humanitarianism and our sense of justice, hold the incendiary torches ready, with nothing to stop the spread of their ideas except the critical reason of a single, fairly intelligent, mentally stable stratum of the population. One should not overestimate the thickness of this stratum. Also it is regionally dependent on public education and is subject to the influence of acutely disturbing factors of a political and economic nature. Taking plebiscites as a criterion, one could on an optimistic estimate put its upper limit at about forty per cent of the electorate. A rather more pessimistic view would not be unjustified either, since the gift of reason and critical reflection is not one of man’s outstanding peculiarities, and even where it exists it proves to be wavering and inconstant, the more so, as a rule, the bigger the political groups are. The mass crushes out the insight and reflection that are still possible with the individual, and this necessarily leads to doctrinaire and authoritarian tyranny if ever the constitutional State should succumb to a fit of weakness.
Rational argument can be conducted with some prospect of success only so long as the emotionality of a given situation does not exceed a certain critical degree. If the affective temperature rises above this level, the possibility of reason’s having any effect ceases and its place is taken by slogans and chimerical wish-fantasies. That is to say, a sort of collective possession results which rapidly develops into a psychic epidemic. Under these conditions all those elements whose existence is merely tolerated as asocial under the rule of reason come to the top. Such individuals are by no means rare curiosities to be met with only in prisons and lunatic asylums. For every manifest case of insanity there are, in my estimation, at least ten latent cases who seldom get to the point of breaking out openly but whose views and behaviour, for all there appearance of normality, are influenced unconsciously by pathological and perverse factors. There are, of course, no medical statistics on the frequency of latent psychoses – for understandable reasons. But even if their number should amount to less than ten times that of the manifest psychoses of manifest criminality, the relatively small percentage of the population figures they represent is more than compensated for by the peculiar dangerousness of these people. Their mental state is that of a collectively excited group ruled by affective judgments and wish-fantasies. In a milieu of this kind they are the adapted ones, and consequently feel quite at home in it…. Their chimerical ideas, sustained by fanatical resentment, appeal to the collective irrationality and find fruitful soil there; they express all those motives and resentments which lurk in more normal people under the cloak of reason and insight. They are, therefore, despite their small number in comparison with the population as a whole, dangerous as sources of infection precisely because the so-called normal person possesses only a limited degree of self-knowledge.”
