To suffer is to produce knowledge.

When the qualification to vote is regulated by years, it is placed on the firmest possible ground, because the qualification is such as nothing but dying before the time can take away; and the equality of Rights, as a principle, is recognized in the act of regulating the exercise. But when Rights are placed upon, or made dependent upon property, they are on the most precarious of all tenures. "Riches make themselves wings, and fly away," and the rights fly with them ; and thus they become lost to the man when they would be of most value.

Who will not commend the wit of astrology? Venus, born out of the sea, hath her exaltation in Pisces.

"They have an engine called the Press whereby the people are deceived."

Lichtenberg ... held something of the following kind: one should neither affirm the existence of God nor deny it. ... It is not that he wished to leave certain perspectives open, nor to please everyone. It is rather that he was identifying himself, for his part, with a consciousness of self, of the world, and of others that was "strange" (the word is his) in a sense which is equally well destroyed by the rival explanations.

Yes, you see the Trinity if you see charity.

I saw men go up and down, In the country and the town, With this tablet on their neck,- 'Judgement and a judge we seek.' Not to monarchs they repair, Nor to learned jurist's chair; But they hurry to their peers, To their kinsfolk and their dears; Louder than with speech they pray,- 'What am I? companion, say.'

What, then, is the animal? First of all, a system of plant-souls. The unity of those plant-souls, which unity nature itself produces, is the soul of the animal. Its world is therefore partly that of the plants - its nourishment, for instance, it receives partly through synthesis from vegetable, and through analysis from animal nature - and partly that of the animals, whereof we shall speak directly. Each product of nature is an organically in-itself completed totality in space, like the plant. Hence, the unknown x which we are looking for must also be such a whole or totality, and in so far it must also have a principle of organization, a sphere and central point of this organization ; in short, the same which we have called the soul of the plant, which thus remains common to both. ... The animal is a system of plant-souls, and the plant is a separated, isolated part of an animal. Both reciprocally affect each other.

Kant's philosophy shifts for the first time the whole of modern thought and being (Desein) into the clarity and transparency of the foundation (Begrundung). This determines every attitude toward knowledge since then, as well as the bounds (Abgrenzungen) and appraisals of the sciences in the nineteenth century up to the present time. Therein Kant towers so far above all who precede and follow that even those who reject him or go beyond him still remain entirely dependent upon him.

I do not mean to be disrespectful, but the attempt of the Lords to stop the progress of reform reminds me very forcibly of the great storm at Sidmouth, and of the conduct of the excellent Mrs Partington on that occasion. In the winter of 1824 there set in a great flood upon that town - the tide rose to an incredible height - the waves rushed in upon the houses, and everything was threatened with destruction. In the midst of this sublime and terrible storm, Dame Partington, who lived upon the beach, was seen at the door of her house with mop and pattens, trundling her mop, squeezing out the sea-water, and vigorously pushing away the Atlantic Ocean. The Atlantic was roused; Mrs. Partington's spirit was up. But I need not tell you that the contest was unequal.

Mind, even more deadly to empires than to individuals, erodes them, compromises their solidity.

If a big diamond is cut up into pieces, it immediately loses its value as a whole; or if an army is scattered or divided into small bodies, it loses all its power; and in the same way a great intellect has no more power than an ordinary one as soon as it is interrupted, disturbed, distracted, or diverted; for its superiority entails that it concentrates all its strength on one point and object, just as a concave mirror concentrates all the rays of light thrown upon it. Noisy interruption prevents this concentration. This is why the most eminent intellects have always been strongly averse to any kind of disturbance, interruption and distraction, and above everything to that violent interruption which is caused by noise; other people do not take any particular notice of this sort of thing.

All the higher, more penetrating ideals are revolutionary. They present themselves far less in the guise of effects of past experience than in that of probable causes of future experience.

A heart without music is like beauty without melancholy.

It was the period of my mental progress which I have now reached that I formed the friendship which has been the honour and chief blessing of my existence, as well as the source of a great part of all that I have attempted to do, or hope to effect hereafter, for human improvement. My first introduction to the lady who, after a friendship of twenty years, consented to become my wife, was in 1830, when I was in my twenty-fifth and she in her twenty-third year.

The deceiver is really the fool.

There is perhaps nothing more interesting than to listen to a superior man talk of what he does not know. He advances slowly, and scarcely puts his foot down without knowing if the ground is solid; he looks for plausible analogies; he tries to attach his ideas to higher and incontestable principles; he always has the tone of looking, never that of teaching; and it often happens that, even if he is mistaken, he leaves a great enough idea of his mental honesty.

We see that experience plays an indispensable role in the genesis of geometry; but it would be an error thence to conclude that geometry is, even in part, an experimental science. If it were experimental it would be only approximative and provisional. And what rough approximation!...The object of geometry is the study of a particular 'group'; but the general group concept pre-exists... in our minds. It is imposed on us, not as form of our sense, but as form of our understanding. Only, from among all the possible groups, that must be chosen... will be... the standard to which we shall refer natural phenomena.Experience guides us in this choice without forcing it upon us; it tells us not which is the truest geometry, but which is the most convenient.Notice that I have been able to describe the fantastic worlds... imagined without ceasing to employ the language of ordinary geometry.

You ask me why I do not write something... I think one's feelings waste themselves in words; they ought all to be distilled into actions and into actions which bring results.

It's my belief that the Universe possesses, in its essence, fractal properties of a very complex sort and that the pursuit of science shares those properties. It follows that any part of the Universe that remains un-understood, and any part of scientific investigation that remains unresolved, however small that might be in comparison to what is understood and resolved, contains within it all the complexity of the original. Therefore, we'll never finish. No matter how far we go, the road ahead will be as long as it was at the start, and that's the secret of the Universe.

Every man, wherever he goes, is encompassed by a cloud of comforting convictions, which move with him like flies on a summer day.

I am a perfect stranger to France, which I have never seen, and I expect nothing from her king, whom I shall never know.

Money is human happiness in the abstract: he, then, who is no longer capable of enjoying human happiness in the concrete devotes his heart entirely to money.

People here argue about religion interminably, but it appears that they are competing at the same time to see who can be the least devout.

If you want to understand the beliefs that are shaping global politics, read the Book of Revelation.

As to love our neighbour as we love ourselves is the great law of Christianity, so it is the great precept of nature to love ourselves only as we love our neighbour, or what comes to the same thing, as our neighbour is capable of loving us. 

And happiness is thought to depend on leisure; for we are busy that we may have leisure, and make war that we may live in peace.

The slaves of our times are not all those factory and workshop hands only who must sell themselves completely into the power of the factory and foundry-owners in order to exist, but nearly all the agricultural laborers are slaves, working, as they do, unceasingly to grow another's corn on another's field, and gathering it into another's barn; or tilling their own fields only in order to pay to bankers the interest on debts they cannot get rid of. And slaves also are all the innumerable footmen, cooks, porters, housemaids, coachmen, bathmen, waiters, etc., who all their life long perform duties most unnatural to a human being, and which they themselves dislike.

Friend!-Will the ballot-box raise the Noblest to the chief place; does any sane man deliberately believe such a thing?

When truth cannot make itself known in words, it will make itself known in deeds.

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.

A grievous crime indeed against religion has been committed by the man who imagines that Islam is defended by the denial of the mathematical sciences.

Opinion is like a pendulum and obeys the same law. If it goes past the centre of gravity on one side, it must go a like distance on the other; and it is only after a certain time that it finds the true point at which it can remain at rest.

All of the days go toward death and the last one arrives there.

The Master said, "He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn towards it."

The difference between a pessimistic and an optimistic mind is of such controlling importance in regard to every intellectual function, and especially for the conduct of life, that it is out of the question to admit that both are normal, and the great majority of mankind are naturally optimistic.

Politics is, as it were, the gizzard of society, full of grit and gravel, and the two political parties are its two opposite halves, - sometimes split into quarters, it may be, which grind on each other. Not only individuals, but States, have thus a confirmed dyspepsia, which expresses itself, you can imagine by what sort of eloquence. Thus our life is not altogether a forgetting, but also, alas! to a great extent, a remembering of that which we should never have been conscious of, certainly not in our waking hours. Why should we not meet, not always as dyspeptics, to tell our bad dreams, but sometimes as eupeptics, to congratulate each other on the ever glorious morning? I do not make an exorbitant demand, surely.

There is no rule more invariable than that we are paid for our suspicions by finding what we suspect.

Fascism is not defined by the number of its victims, but by the way it kills them.

Marcus Garvey, Elijah Muhammad, Malcolm X, Martin Luther King, Stokely Carmichael, Amiri Baraka and other black male leaders have righteously supported patriarchy. They have all argued that it is absolutely necessary for black men to relegate black women to a subordinate position both in the political sphere and in home life.

The Austrians are a highly civilised race, half-surrounded by Slavs in a relatively backward state of culture. ... Servia, a country so barbaric that a man can secure the throne by instigating the assassination of his predecessor, is engaged constantly in fermenting the racial discontent of men of the same race who are Austrian subjects.

Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly if they even roll a few more upon it. A strength which becomes clearer and stronger through its experience of such obstacles is the only strength that can conquer them. Resistance is only a waste of strength.

The images of mankind have become the most basic thing about them. And they're all software, and disembodied.

Finally, and... somewhat belatedly, there is the growing of a left that... has now been energized and is increasingly vocal... in certain quarters of the cultural community, in the arts and the universities, in Hollywood, in the media... where in some versions it also engages in a kind of illiberal... politics.

For a woman, the typical danger emanating from the unconscious comes from above, from the "spiritual" sphere personified by the animus, whereas for a man it comes from the chthonic realm of the "world and woman," i.e., the anima projected on to the world.

Patriots always talk of dying for their country, and never of killing for their country.

That which is desirable on its own account and for the sake of knowing it is more of the nature of wisdom than that which is desirable on account of its results.
