The first theory is that if we make the rich richer, somehow they will let a part of their prosperity trickle down to the rest of us. The second theory was the theory that if we make the average of mankind comfortable and secure, their prosperity will rise upward through the ranks.

Here is the world, sound as a nut, perfect, not the smallest piece of chaos left, never a stitch nor an end, not a mark of haste, or botching, or second thought; but the theory of the world is a thing of shreds and patches.

I believe what really happens in history is this: the old man is always wrong; and the young people are always wrong about what is wrong with him. The practical form it takes is this: that, while the old man may stand by some stupid custom, the young man always attacks it with some theory that turns out to be equally stupid.

If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience.

Einstein is the only figure in the physical sciences with a stature that can be compared with Newton. Newton is reported to have said "If I have seen further than other men, it is because I stood on the shoulders of giants." This remark is even more true of Einstein who stood on the shoulders of Newton. Both Newton and Einstein put forward a theory of mechanics and a theory of gravity but Einstein was able to base General Relativity on the mathematical theory of curved spaces that had been constructed by Riemann while Newton had to develop his own mathematical machinery. It is therefore appropriate to acclaim Newton as the greatest figure in mathematical physics and the Principia is his greatest achievement.

The dualistic philosophy reigned supreme in Europe, dominating the development of Western science. But with the advent of atomic physics, findings based on demonstrable experiment were seen to negate the dualistic theory, and the trend of thought since then has been back to the monistic conception of the ancient Taoists.

It has become a commonplace that aggressiveness also often has its roots in fear. I am inclined to think that this theory has been pushed too far. [...] The type of aggressiveness that is the outcome of timidity is not, I think, that which inspires great leaders; the great leaders, I should say, have an exceptional self-confidence which is not only on the surface, but penetrates deep into the subconscious.

In the Theory of Numbers it happens rather frequently that, by some unexpected luck, the most elegant new truths spring up by induction.

What can a man say about woman, his own opposite? I mean of course something sensible, that is outside the sexual program, free of resentment, illusion, and theory. Where is the man to be found capable of such superiority? Woman always stands just where the man's shadow falls, so that he is only too liable to confuse the two. Then, when he tries to repair this misunderstanding, he overvalues her and believes her the most desirable thing in the world.

In a Society in which there is no law, and in theory no compulsion, the only arbiter of behaviour is public opinion. But public opinion, because of the tremendous urge to conformity in gregarious animals, is less tolerant than any system of law. When human beings are governed by "thou shalt not", the individual can practise a certain amount of eccentricity: when they are supposedly governed by "love" or "reason", he is under continuous pressure to make him behave and think in exactly the same way as everyone else.

We may sum up as follows: According to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, an ether exists. Space without an ether is inconceivable.

You see, I divide men into three categories: those who have a lot of money, those who have none at all and those who have a little. The first want to keep what they have: their interest is to maintain order; the second want to take what they do not have: their interest is to destroy the existing order and to establish one which is profitable to them. They each are realist, people with whom one can agree. The third group want to overthrow the social order to take what they do not have, while still preserving it so that no one takes away what they have. Thus, they preserve in fact what they destroy in theory, or they destroy in fact what they seem to preserve. Those are the idealists.

Einstein's relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists.

In theory one is aware that the earth revolves, but in practice one does not perceive it, the ground upon which one treads seems not to move, and one can live undisturbed. So it is with Time in one's life.

In the natural state no concept of God can arise, and the false one which one makes for himself is harmful. Hence the theory of natural religion can be true only where there is no science; therefore it cannot bind all men together.

My faith in the reliability of the theory still fluctuates... Thus, if not all systems of equations of the theory... admit transformations other than linear ones, then the theory contradicts its own starting point and all is up in the air.

Human experience, which is constantly contradicting theory, is the great test of truth. A system, built upon the discoveries of a great many minds, is always of more strength, than what is produced by the mere workings of any one mind, which, of itself, can do very little. There is not so poor a book in the world that would not be a prodigious effort were it wrought out entirely by a single mind, without the aid of prior investigators.

The theory of free speech, that truth is so much larger and stranger and more many-sided than we know of, that it is very much better at all costs to hear everyone's account of it, is a theory which has been justified on the whole by experiment, but which remains a very daring and even a very surprising theory. It is really one of the great discoveries of the modern time.

Fundamental ideas play the most essential role in forming a physical theory. Books on physics are full of complicated mathematical formulae. But thought and ideas, not formulae, are the beginning of every physical theory. The ideas must later take the mathematical form of a quantitative theory, to make possible the comparison with experiment.
Albert Einstein

The sole purpose of physical theory is to provide a representation and classification of experimental laws; the only test permitting us to judge a physical theory and pronounce it good or bad is the comparison between the consequences of this theory and the experimental laws it has to represent and classify.
