The human race's prospects of survival were considerably better when we were defenceless against tigers than they are today when we have become defenceless against ourselves.

We have been God-like in our planned breeding of our domesticated plants and animals, but we have been rabbit-like in our unplanned breeding of ourselves.

As human beings, we are endowed with freedom of choice, and we cannot shuffle off our responsibility upon the shoulders of God or nature. We must shoulder it ourselves. It is our responsibility.

Civilization is a movement and not a condition, a voyage and not a harbor.

We shall have to share out the fruits of technology among the whole of mankind. The notion that the direct and immediate producers of the fruits of technology have a proprietary right to these fruits will have to be forgotten. After all, who is the producer? Man is a social animal, and the immediate producer has been helped to produce by the whole structure of society, beginning with his own education.

Of the twenty-two civilizations that have appeared in history, nineteen of them collapsed when they reached the moral state the United States is in now.

Of the twenty or so civilizations known to modern Western historians, all except our own appear to be dead or moribund, and, when we diagnose each case... we invariably find that the cause of death has been either War or Class or some combination of the two.
