"Endow scientific research and we shall know the truth, when and where it is possible to ascertain it;" but the counterblast is at hand: "To endow research is merely to encourage the research for endowment; the true man of science will not be held back by poverty, and if science is of use to us, it will pay for itself." Such are but a few samples of the conflict of opinion which we find raging around us.

The unity of all science consists alone in its method, not in its material.

There is no short cut to truth, no way to gain a knowledge of the universe except through the gateway of scientific method.

All great scientists have, in a certain sense, been great artists; the man with no imagination may collect facts, but he cannot make great discoveries.

Order and reason, beauty and benevolence, are characteristics and conceptions which we find solely associated with the mind of man.

The right to live does not connote the right of each man to reproduce his kind ... As we lessen the stringency of natural selection, and more and more of the weaklings and the unfit survive, we must increase the standard, mental and physical, of parentage.

No matter how much we enjoy following the lives of the rich and famous, we know the world is affected more deeply by quiet, even invisible acts of integrity, kindness, and generosity, than by fame and fortune.
