History not used is nothing, for all intellectual life is action, like practical life, and if you don't use the stuff - well, it might as well be dead.

The West has never been all of the world that matters. The West has not been the only actor on the stage of modern history even at the peak of the West's power (and this peak has perhaps now already been passed)... It has not been the West that has been hit by the world; it has been the world that has been hit - and hit hard - by the West.

Our western science is a child of moral virtues; and it must now become the father of further moral virtues if its extraordinary material triumphs in our time are not to bring human history to an abrupt, unpleasant and discreditable end.

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.

Immaturity means self-centeredness, inability to compromise, to rise above hurt feelings, to postpone immediate pleasures in favor of future benefits, or to do unpleasant chores when they need to be done.

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.

I regard the state of which I am a citizen as a public utility, like the organization that supplies me with water, gas, and electricity. I feel that it is my civic duty to pay my taxes as well as my other bills, and that it is my moral duty to make an honest declaration of my income to the income tax authorities. But I do not feel that I and my fellow citizens have a religious duty to sacrifice our lives in war on behalf of our own state, and, a fortiori, I do not feel that we have an obligation or a right to kill and maim citizens of other states or to devastate their land.
