I realized that more and more I was saying, "It seems to me that we have come to the time war ought to be given up. It no longer makes sense to kill 20 million or 40 million people because of a dispute between two nations who are running things, or decisions made by the people who really are running things. It no longer makes sense. Nobody wins. Nobody benefits from destructive war of this sort and there is all of this human suffering." And Einstein was saying the same thing of course. So that is when we decided — my wife and I — that first, I was pretty effective as a speaker. Second, I better start boning up, studying these other fields so that nobody could stand up and say, "Well, the authorities say such and such "

The only sane policy for the world is that of abolishing war.

We must not have a Nuclear war. We must begin to solve international disputes by the application of man's power of reason in a way that is worthy of the dignity of man. We must solve them by arbitration, negotiation, and the development of international law, the making of international agreements that will do justice to all nations and to all peoples and will benefit all nations and to all people. Now is the time to start.

We may, I believe, anticipate that the chemist of the future who is interested in the structure of proteins, nucleic acids, polysaccharides, and other complex substances with high molecular weight will come to rely upon a new structural chemistry, involving precise geometrical relationships among the atoms in the molecules and the rigorous application of the new structural principles, and that great progress will be made, through this technique, in the attack, by chemical methods, on the problems of biology and medicine.

Science cannot be stopped. Man will gather knowledge no matter what the consequences – and we cannot predict what they will be. Science will go on — whether we are pessimistic, or are optimistic, as I am. I know that great, interesting, and valuable discoveries can be made and will be made… But I know also that still more interesting discoveries will be made that I have not the imagination to describe — and I am awaiting them, full of curiosity and enthusiasm.

A substance showing resonance between two or more valence-bond structures does not contain molecules with the configurations and properties usually associated with these structures.

The power to destroy the world by the use of nuclear weapons is a power that cannot be used - we cannot accept the idea of such monstrous immorality.The time has now come for morality to take its proper place in the conduct of world affairs; the time has now come for the nations of the world to submit to the just regulation of their conduct by international law.

Planck’s constant and the quantum theory that is built around it are of extreme importance for chemistry—we may well be justified in saying that quantum theory is of greater importance to chemistry than to physics ... there is no part of chemistry that does not depend, in its fundamental theory, upon quantum principles.
