German-American physicist (1879-1955)

Albert Einstein quote

E = mc²

ALBERT EINSTEIN, Annalen der Physik, Sep. 27, 1905

Physical concepts are free creations of the human mind, and are not, however it may seem, uniquely determined by the external world.

ALBERT EINSTEIN, The Evolution of Physics

Peace cannot be kept by force. It can only be achieved by understanding.

ALBERT EINSTEIN, speech to the New History Society, Dec. 14, 1930

A man's ethical behavior should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.

ALBERT EINSTEIN, New York Times Magazine, November 9, 1930

We should take care not to make the intellect our god; it has, of course, powerful muscles, but no personality.

ALBERT EINSTEIN, as quoted in Jerry Mayer's Bite-Size Einstein

Imagination is more important than knowledge.


The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.


The really valuable thing in the pageant of human life seems to me not the State but the creative, sentient individual, the personality; it alone creates the noble and the sublime, while the herd as such remains dull in thought and dull in feeling.

ALBERT EINSTEIN, The World as I See it

I cannot conceive of a God who rewards and punishes his creatures, or has a will of the type of which we are conscious in ourselves. An individual who should survive his physical death is also beyond my comprehension, nor do I wish it otherwise; such notions are for the fears or absurd egoism of feeble souls.

ALBERT EINSTEIN, The World as I See it

Nothing will benefit human health and increase chances for survival of life on Earth as much as the evolution to a vegetarian diet.

ALBERT EINSTEIN, letter to Harmann Huth, Dec. 27, 1930

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

ALBERT EINSTEIN, attributed, "The Universe and Dr. Einstein", Harper's Magazine, May 1948

Life is like riding a bicycle. To keep your balance you must keep moving.

ALBERT EINSTEIN, Woman's Day Magazine, Jun. 1, 2007

Whoever undertakes to set himself up as a judge of Truth and Knowledge is shipwrecked by the laughter of the gods.

ALBERT EINSTEIN, Ideas and Opinions: Based on Mein Weltbild

Everything that is really great and inspiring is created by the individual who can labor in freedom.

ALBERT EINSTEIN, Out of My Later Years

I have never looked upon ease and happiness as ends in themselves--such an ethical basis I call more proper for a herd of swine.


I do not know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

I cannot imagine a God who rewards and punishes the objects of his creation, whose purposes are modeled after our own--a God, in short, who is but a reflection of human frailty.

ALBERT EINSTEIN, Living Philosophies

Nature only shows us the tail of the lion. I am convinced, however, that the lion is attached to it, even though he cannot reveal himself directly because of his enormous size.

ALBERT EINSTEIN, letter to H. Zangger, Mar. 10, 1914, The Collected Papers of Albert Einstein

When a man sits with a pretty girl for an hour, it seems like a minute. But let him sit on a hot stove for a minute and it's longer than any hour. That's relativity.


Insanity: doing the same thing over and over again and expecting different results.


Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.


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

ALBERT EINSTEIN, Out of My Later Years

My religion consists of a humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind.


It has become appallingly obvious that our technology has exceeded our humanity.


It is harder to crack a prejudice than an atom.


God is subtle, but he is not malicious.

ALBERT EINSTEIN, remark made during Einstein's first visit to Princeton University, Apr. 1921

I have second thoughts. Maybe God is malicious.

ALBERT EINSTEIN, remark to Vladimir Bargmann, quoted in Einstein in America (1985)

I do not know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

ALBERT EINSTEIN, Liberal Judaism, Apr/May 1949

Education is what remains after one has forgotten everything he learned in school.


The secret to creativity is knowing how to hide your sources.


As our circle of knowledge expands, so does the circumference of darkness surrounding it.


Unthinking respect for authority is the greatest enemy of truth.

ALBERT EINSTEIN, letter to Jost Winteler, 1901

I have repeatedly said that in my opinion the idea of a personal God is a childlike one. You may call me an agnostic, but I do not share the crusading spirit of the professional atheist whose fervor is mostly due to a painful act of liberation from the fetters of religious indoctrination received in youth. I prefer an attitude of humility corresponding to the weakness of our intellectual understanding of nature and of our own being.

ALBERT EINSTEIN, letter to Guy H. Raner Jr., Sep. 28, 1949

One ought to be ashamed to make use of the wonders of science embodied in a radio set, the while appreciating them as little as a cow appreciates the botanic marvels in the plants she munches.

ALBERT EINSTEIN, "On Radio," Einstein on Cosmic Religion and Other Opinions and Aphorisms

Perfection of means and confusion of goals seem—in my opinion—to characterize our age.

ALBERT EINSTEIN, "The Common Language of Science," Sep. 28, 1941

Albert Einstein quote

I am not only a pacifist but a militant pacifist. I am willing to fight for peace. Nothing will end war unless the people themselves refuse to go to war.

ALBERT EINSTEIN, interview with George Sylvester Viereck, Jan. 1931

Our entire much-praised technological progress, and civilization generally, could be compared to an axe in the hand of a pathological criminal.

ALBERT EINSTEIN, letter to H. Zangger, 1917

Elsa tells me that you are unhappy because you didn't get to see your Uncle Einstein. Therefore I will tell you what I look like: pale face, long hair, and a modest paunch. In addition, an awkward gait, a cigar--if I happen to have one--in the mouth, and a pen in the pocket or hand. But this uncle doesn't have bowed legs or warts, and is therefore quite handsome; and neither does he have hair on his hands, as ugly men often do. So indeed it is a pity that you didn't get to see me.

ALBERT EINSTEIN, letter to Elisabeth Ley, Sep. 30, 1920

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 any closer to the secret of the "old one." I, at any rate, am convinced that He does not throw dice.

ALBERT EINSTEIN, letter to Max Born, Dec. 4, 1926

An important advance in the life of a people is the transformation of the religion of fear into the moral religion. But one must avoid the prejudice that regards the religions of primitive peoples as pure fear religions and those of the civilized races as pure moral religions. All are mixed forms, though the moral element predominates in the higher levels of social life. Common to all these types is the anthropomorphic character of the idea of God.

ALBERT EINSTEIN, Cosmic Religion and Other Opinions and Aphorisms

Anyone who has never made a mistake has never tried anything new.


Reality is merely an illusion, albeit a very persistent one.
