If melodiously piping flutes sprang from the olive, would you doubt that a knowledge of flute-playing resided in the olive? And what if plane trees bore harps which gave forth rhythmical sounds? Clearly you would think in the same way that the art of music was possessed by plane trees. Why, then, seeing that the universe gives birth to beings that are animate and wise, should it not be considered animate and wise itself?

All the cases in which means and ends are external to one another are non-esthetic.

The capitalist system of production is an economic democracy in which every penny gives a right to vote. The consumers are the sovereign people. The capitalists, the entrepreneurs, and the farmers are the people's mandatories. If they do not obey, if they fail to produce, at the lowest possible cost, what the consumers are asking for, they lose their office. Their task is service to the consumer. Profit and loss are the instruments by means of which the consumers keep a tight rein on all business activities.

The problems are dissolved in the actual sense of the word - like a lump of sugar in water.

How can great minds be produced in a country where the test of a great mind is agreeing in the opinions of small minds?

Each of us is born with a share of purity, predestined to be corrupted by our commerce with mankind, by that sin against solitude.

A man living without conflicts, as if he never lives at all.

To tell the truth, I couldn't care less about the relativity of knowledge, simply because the world does not deserve to be known.

A loving heart is the beginning of all knowledge.

I have come to believe that the motion of the Earth cannot be detected by any optical experiment.

Mathematics, rightly viewed, possesses not only truth, but supreme beauty - a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of highest excellence, is to be found in mathematics as surely as in poetry. What is best in mathematics deserves not merely to be learnt as a task, but to be assimilated as a part of daily thought, and brought again and again before the mind with ever-renewed encouragement.

The prophet is appointed to oppose the king, and even more: history.

Our dignity is not in what we do, but in what we understand.

If there be any among us who would wish to dissolve this Union or to change its republican form, let them stand undisturbed as monuments of the safety with which error of opinion may be tolerated where reason is left free to combat it.

Logos is the formal cause of the kosmos and all things, responsible for their nature and configuration.

The cause and root of nearly all evils in the sciences is this - that while we falsely admire and extol the powers of the human mind we neglect to seek for its true helps.

When a sixth of the population of a nation which has undertaken to be the refuge of liberty are slaves, and a whole country is unjustly overrun and conquered by a foreign army, and subjected to military law, I think that it is not too soon for honest men to rebel and revolutionize. What makes this duty the more urgent is the fact that the country so overrun is not our own, but ours is the invading army.

The worker's existence is thus brought under the same condition as the existence of every other commodity. The worker has become a commodity, and it is a bit of luck for him if he can find a buyer, And the demand on which the life of the worker depends, depends on the whim of the rich and the capitalists.

In the ceremonies of the public execution, the main character was the people, whose real and immediate presence was required for the performance.

When one is gripped by excruciating physical pain, one is always shocked at just how frightful it can be.

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

I believe in intuition and inspiration. ... At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

India is pre-eminently distinguished for the many traits of original grandeur of thought and of the wonderful remains of immediate knowledge.

Love is something far more than desire for sexual intercourse; it is the principal means of escape from the loneliness which afflicts most men and women throughout the greater part of their lives.

If you feel irritated by the absurd remarks of two people whose conversation you happen to overhear, you should imagine that you are listening to a dialogue of two fools in a comedy.

The desire to die was my one and only concern; to it I have sacrificed everything, even death.

The diversity of physical arguments and opinions embraces all sorts of methods.

Haven't people learned yet that the time of superficial intellectual games is over, that agony is infinitely more important than syllogism, that a cry of despair is more revealing than the most subtle thought, and that tears always have deeper roots than smiles?

As far as I am concerned, I resign from humanity. I no longer want to be, nor can still be, a man. What should I do? Work for a social and political system, make a girl miserable? Hunt for weaknesses in philosophical systems, fight for moral and aesthetic ideals? It's all too little. I renounce my humanity even though I may find myself alone. But am I not already alone in this world from which I no longer expect anything?

Whether you can observe a thing or not depends on the theory which you use. It is the theory which decides what can be observed.

The only thing that will redeem mankind is co-operation, and the first step towards co-operation lies in the hearts of individuals.

Every nation gets the government it deserves.

Neither is the longing for immortality saved, but rather dissolved and submerged, by agnosticism, or the doctrine of the unknowable. ...The unknowable, if it is something more than the merely hitherto unknown, is but a purely negative concept, a concept of limitation. And upon this foundation no human feeling can be built up.

I have come to believe that the motion of the Earth cannot be detected by any optical experiment.

And wonderful it is to see how the Ideal or Soul, place it in what ugliest Body you may, will irradiate said Body with its own nobleness; will gradually, incessantly, mould, modify, new-form or reform said ugliest Body, and make it at last beautiful, and to a certain degree divine!

"What," say you, "are you giving me advice? Indeed, have you already advised yourself, already corrected your own faults? Is this the reason why you have leisure to reform other men?" No, I am not so shameless as to undertake to cure my fellow-men when I am ill myself. I am, however, discussing with you troubles which concern us both, and sharing the remedy with you, just as if we were lying ill in the same hospital.

In the days before machinery men and women who wanted to amuse themselves were compelled, in their humble way, to be artists. Now they sit still and permit professionals to entertain them by the aid of machinery. It is difficult to believe that general artistic culture can flourish in this atmosphere of passivity.

Probability fractions arise from our knowledge and from our ignorance.

The "imagination that shudders at the Hell of Dante," is not that the same faculty, weaker in degree, as Dante's own? No one but Shakspeare can embody, out of Saxo Grammaticus, the story of Hamlet as Shakspeare did: but every one models some kind of story out of it; every one embodies it better or worse. We need not spend time in defining. Where there is no specific difference, as between round and square, all definition must be more or less arbitrary. A man that has so much more of the poetic element developed in him as to have become noticeable, will be called Poet by his neighbors.

The suppression of liberty is always likely to be irrational.

Time, and reflection, and discussion, have produced their natural effect on minds eminently intelligent and candid. No intermediate shades of opinion are now left. There is no twilight. The light has been divided from the darkness. Two parties are ranged in battle array against each other. There is the standard of monopoly. Here is the standard of free trade; and by the standard of free trade I pledge myself to stand firmly.

Our aim is precisely to establish the human kingdom as a pattern of values in distinction from the material world. But the subjectivity which we thus postulate as the standard of truth is no narrowly individual subjectivism, for as we have demonstrated, it is not only one's own self that one discovers in the cogito, but those of others too. Contrary to the philosophy of Descartes, contrary to that of Kant, when we say "I think" we are attaining to ourselves in the presence of the other, and we are just as certain of the other as we are of ourselves. Thus the man who discovers himself directly in the cogito also discovers all the others, and discovers them as the condition of his own existence. He realizes that he can't be anything unless others recognize him as such. I cannot obtain any truth whatsoever about myself, except through the mediation of another. The other is indispensable to my existence, and equally so to any knowledge I can have of myself.

No man ought to glory except in that which is his own.

We have no right to believe a thing true because everybody says so unless there are good grounds for believing that some one person at least has the means of knowing what is true, and is speaking the truth so far as he knows it. However many nations and generations of men are brought into the witness-box they cannot testify to anything which they do not know. Every man who has accepted the statement from somebody else, without himself testing and verifying it, is out of court; his word is worth nothing at all. And when we get back at last to the true birth and beginning of the statement, two serious questions must be disposed of in regard to him who first made it: was he mistaken in thinking that he knew about this matter, or was he lying?

Speaking as of today, I do not consider it intellectually respectable to be a partisan in matters of religion. I see religion as I see such other basic fascinations as art and science, in which there is room for many different approaches, styles, techniques, and opinions. Thus I am not formally a committed member of any creed or sect and hold no particular religious view or doctrine as absolute. I deplore missionary zeal, and consider excessive dedication to and advocacy of any particular religion, as either the best or the only true way, an almost irreligious arrogance. Yet my work and my life are fully concerned with religion, and the mystery of being is my supreme fascination, though, as a shameless mystic, I am more interested in religion as feeling and experience than as conception and theory.

Every step of real movement is more important than a dozen programmes.

Whenever a man talks he lies, and so far as he talks to himself - that is to say, so far as he thinks, knowing that he thinks - he lies to himself. The only truth in human life is that which is physiological. Speech - this thing that they call a social product - was made for lying.
