My religion consists of a humble admiration of the unlimitable superior who reveals Himself in the slight details we are able to perceive with our frail and feeble minds. That deeply emotional convictionof the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.

The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.

No amount of experimentation can ever prove me right; a single experiment can prove me wrong.

The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.

Common sense is the collection of prejudices acquired by age eighteen.

Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing.  The theory says a lot, but does not really bring us closer to the secret of the 'Old One.' I, at any rate, am convinced that He is not playing at dice.

Try not to become a man of success but rather to become a man of value.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.

There are only two ways to live your life. One is as though nothing is a miracle. The other is as if everything is. I believe in the latter.

The highest destiny of the individual is to serve rather than to rule.

 The difference between stupidity and genius is that genius has its limits.

The Lord God is subtle, but malicious He is not.
    {Inscribed in Fine Hall, Princeton University}

Science without religion is lame. Religion without science is blind.

 The problems that exist in the world today cannot be solved by the level of thinking that created them.

To know that what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull facilities can comprehend only in the most primitive forms--this knowledge, this feeling, is at the center of true religiousness. In this sense, and in this sense only, I belong to the ranks of the devoutly religious men.
    {What I Believe, 1931}

Everything is determined, the beginning as well as the end, by forces over which we have no control.  It is determined for insects as well as for the stars. Human beings, vegetables or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.
