“No tree, it is said, can grow to heaven unless its roots reach down to hell.”

“Our heart glows, and secret unrest gnaws at the root of our being. Dealing with the unconscious has become a question of life for us.”

“Our mania for rational explanations obviously has its roots in our fear of metaphysics, for the two were always hostile brothers. Hence, anything unexpected that approaches us from the dark realm is regarded either as coming from outside and, therefore, as real, or else as a hallucination and, therefore, not true. The idea that anything could be real or true which does not come from outside has hardly begun to dawn on contemporary man.”

“Heaven has become for us the cosmic space of the physicists... But 'the heart glows,' and a secret unrest gnaws at the roots of our being.”

“The less we understand of what our fathers and forefathers sought, the less we understand ourselves, and thus we help with all our might to rob the individual of his roots and his guiding instincts, so that he becomes a particle in the mass, ruled only by what Nietzsche called the spirit of gravity.”

“The greatest and most important problems of life are all in a certain sense insoluble…. They can never be solved, but only outgrown…. This ‘outgrowing’, as I formerly called it, on further experience was seen to consist in a new level of consciousness. Some higher or wider interest arose on the person’s horizon, and through this widening of view, the insoluble problem lost its urgency. It was not solved logically in its own terms, but faded out when confronted with a new and stronger life-tendency.”

“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.”
