Man is the only animal that can be bored.

On the whole, our modern ritual is impoverished and does not fulfill man's need for collective art and ritual.

The pace of science forces the pace of technique. Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced -- by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.

Modern man lives under the illusion that he knows what he wants, while he actually wants what he is supposed to want.

I believe that the unity of man as opposed to other living things derives from the fact that man is the conscious life of himself. Man is conscious of himself, of his future, which is death, of his smallness, of his impotence; he is aware of others as others; man is in nature, subject to its laws even if he transcends it with his thought.

I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.

Every act of irreverence for life, every act which neglects life, which is indifferent to and wastes life, is a step towards the love of death. This choice man must make at every minute. Never were the consequences of the wrong choice as total and as irreversible as they are today. Never was the warning of the Bible so urgent: 'I have put before you life and death, blessing and curse. Choose life, that you and your children may live.'

The history of man is a graveyard of great cultures that came to catastrophic ends because of their incapacity for planned, rational, voluntary reaction to challenge.

The criterion of mental health is not one of individual adjustment to a given social order, but a universal one, valid for all men, of giving a satisfactory answer to the problem of human existence.
