In order to obtain and hold power a man must love it. Thus the effort to get it is not likely to be coupled with goodness, but with the opposite qualities of pride, craft and cruelty.

Man by violating his own feelings becomes cruel. And how deeply seated in the human heart is the injunction not to take life.

I know that most men, including those at ease with problems of the greatest complexity, can seldom accept even the simplest and most obvious truth if it be such as would oblige them to admit the falsity of conclusions which they have delighted in explaining to colleagues, which they have proudly taught to others, and which they have woven, thread by thread, into the fabric of their lives.

If, then, I were asked for the most important advice I could give, that which I considered to be the most useful to the men of our century, I should simply say: in the name of God, stop a moment, cease your work, look around you.

Here I am...wanting to accomplish something and completely forgetting it must all end--that there is such a thing as death.

Human science fragments everything in order to understand it, kills everything in order to examine it.

As often happens between men who have chosen different pursuits, each, while in argument justifying the other's activity, despised it in the depth of his heart.
