I don't aspire to be a good man. I aspire to be a whole man. - Carl Jung

The change of character brought about by the uprush of collective forces is amazing. A gentle and reasonable being can be transformed into a maniac or a savage beast. One is always inclined to lay the blame on external circumstances, but nothing could explode in us if it had not been there. As a matter of fact, we are constantly living on the edge of a volcano, and there is, so far as we know, no way of protecting ourselves from a possible outburst that will destroy everybody within reach. It is certainly a good thing to preach reason and common sense, but what if you have a lunatic asylum for an audience or a crowd in a collective frenzy? There is not much difference between them because the madman and the mob are both moved by impersonal, overwhelming forces.

... (because) the only real danger that exists is men himself. He is the great danger and we are pityfully unaware of it. We know nothing of men. Far too little ...

Carl Gustav Jung, 1959 in an interview with John Freeman ( youtube watch?v=2AMu-G51yTY 38:04)

One of the most difficult tasks men can perform, however much others may despise it, is the invention of good games.
