When men are engaged in war and conquest, the tools of science become as dangerous as a razor in the hands of a child of three. We must not condemn man because his inventiveness and patient conquest of the forces of nature are being exploited for false and destructive purposes. Rather, we should remember that the fate of mankind hinges entirely upon man’s moral development.

God is clever, but not dishonest.
-
Science has gone a long way toward helping man to free himself from the burden of hard labor; yet, science itself is not a liberator. It creates means, not goals. It is up to men to utilize those means to achieve reasonable goals.
-
When the number of factors coming into play in a phenomenological complex is too large scientific method in most cases fails. One need only think of the weather, in which case the prediction even for a few days ahead is impossible.
-
But there is another reason for the high repute of mathematics: it is mathematics that offers the exact natural sciences a certain measure of security which, without mathematics, they could not attain.
-
Intuitive powers played a central role in my scientific work, not wild speculation, yet a valued resource when no other approach was available.
-
He who can no longer pause to wonder and stand rapt in awe, is as good as dead; his eyes are closed.
-
The more success the quantum theory has, the sillier it looks.

Any man who can drive safely while kissing a pretty girl is simply not giving the kiss the attention it deserves.
-
A society's competitive advantage will come not from how well its schools teach the multiplication and periodic tables, but from how well they stimulate imagination and creativity.
-
The legs are the wheels of creativity.
-
But then, after all, we are all alike, for we are all derived from the monkey.
-
The only rational way of educating is to be an example. If one can't help it, a warning example.
-
While I am a convinced pacifist there are circumstances in which I believe the use of force is appropriate - namely, in the face of an enemy unconditionally bent on destroying me and my people.
-
The true value of a human being can be found in the degree to which he has attained liberation from the self.
-
When you sit with a nice girl for two hours, it seems like two minutes; when you sit on a hot stove for two minutes, it seems like two hours. That's relativity.
-
It appears dubious whether a field theory can account for the atomistic structure of matter and radiation as well as of quantum phenomena.
-
Try and penetrate with our limited means the secrets of nature and you will find that, behind all the discernible concatenations, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion. To that extent I am, in point of fact, religious.
-
Ethical axioms are founded and tested not very differently from the axioms of science. Truth is what stands the test of experience.
-
I refuse to engage in an intellectual battle with an unarmed man.
-
About Newton: Nature to him was an open book, whose letters he could read without effort.
-
How can it be that mathematics, being after all a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things?
-
An expert is a person who has few new ideas; a beginner is a person with many.
-
It seems to me that the idea of a personal God is an anthropological concept which I cannot take seriously. I feel also not able to imagine some will or goal outside the human sphere. My views are near those of Spinoza: admiration for the beauty of and belief in the logical simplicity of the order which we can grasp humbly and only imperfectly. I believe that we have to content ourselves with our imperfect knowledge and understanding and treat values and moral obligations as a purely human problem-the most important of all human problems.
