In formal logic, a contradiction is the signal of a defeat; but in the evolution of real knowledge it marks the first step in progress towards a victory.

A work of art bears within itself its own verification: conceptions which are devised or stretched do not stand being portrayed in images, they all come crashing down, appear sickly and pale, convince no one. But those works of art which have scooped up the truth and presented it to us as a living force - they take hold of us, compel us, and nobody ever, not even in ages to come, will appear to refute them.

The transition of the subject-object relation to that of the I-Thou implies a passage of consciousness to a new sphere of existence, viz, the interval, betweenness or Zwischen; and this is a passage from thought to Umfassung.

Pray go back and recollect one of the conclusions to which I sought to lead you in my very first lecture. You may remember how I there argued against the notion that the worth of a thing can be decided by its origin. Our spiritual judgment, I said, our opinion of the significance and value of a human event or condition, must be decided on empirical grounds exclusively. If the fruits for life of the state of conversion are good, we ought to idealize and venerate it, even though it be a piece of natural psychology; if not, we ought to make short work of it, no matter what supernatural being may have infused it.

By quarrelling amongst themselves, instead of confederating, Germans and Scandinavians, both of them belonging to the same great race, only prepare the way for their hereditary enemy, the Slav. 

You, Socrates, began by saying that virtue can't be taught, and now you are insisting on the opposite, trying to show that all things are knowledge, justice, soundness of mind, even courage, from which it would follow that virtue most certainly can be taught.

Some words shall herein be capitalised when used, not as vernacular, but as terms defined. Thus an "idea" is the substance of an actual unitary thought or fancy; but "Idea," nearer Plato's idea of ἰδέα, denotes anything whose Being consists in its mere capacity for getting fully represented, regardless of any person's faculty or impotence to represent it.

It is not calling the landed estates, possessed by old prescriptive rights, the 'accumulations of ignorance and superstition', that can support me in shaking that grand title, which supersedes all other title, and which all my studies of general jurisprudence have taught me to consider as one principal cause of the formation of states; I mean the ascertaining and securing prescription. But these are donations made in 'ages of ignorance and superstition'. Be it so. It proves that these donations were made long ago; and this is prescription; and this gives right and title.

Be ruled by time, the wisest counsellor of all.

We have a priori reasons for believing that in every sentence there is some one order of words more effective than any other; and that this order is the one which presents the elements of the proposition in the succession in which they may be most readily put together.

It is a serious question among them whether they [Africans] are descended from monkeys or whether the monkeys come from them. Our wise men have said that man was created in the image of God. Now here is a lovely image of the Divine Maker: a flat and black nose with little or hardly any intelligence. A time will doubtless come when these animals will know how to cultivate the land well, beautify their houses and gardens, and know the paths of the stars: one needs time for everything.

Invention is the mother of all necessities.

The state is therefore everyone; the rules within the state are laws which safeguard the welfare of all and which must originate from the welfare of all.

Whoever abhors the name and fancies that he is godless - when he addresses with his whole devoted being the Thou of his life that cannot be restricted by any other, he addresses God.

Fear of evil is greater than the evil itself.

The fact is he made a prodigious blunder in commencing the attack, and now his only chance is to be silent and let people forget the exposure. I do not believe that in the whole history of science there is a case of any man of reputation getting himself into such a contemptible position.

Those who used to sacrifice animals did not take them for beasts. And even the Middle Ages, which condemned and punished them in due form, was in this way much closer to them than we are, we who are filled with horror at this practice. They held them to be guilty: which was a way of honoring them. We take them for nothing, and it is on this basis that we are "human" with them. We no longer sacrifice them, we no longer punish them, and we are proud of it, but it is simply that we have domesticated them, worse: that we have made of them a racially inferior world, no longer even worthy of our justice, but only of our affection and social charity, no longer worthy of punishment and of death, but only of experimentation and extermination like meat from the butchery.

I have lived through much, and now I think I have found what is needed for happiness. A quiet secluded life in the country, with the possibility of being useful to people to whom it is easy to do good, and who are not accustomed to have it done to them; then work which one hopes may be of some use; then rest, nature, books, music, love for one's neighbor -- such is my idea of happiness. And then, on the top of all that, you for a mate, and children perhaps -- what more can the heart of man desire?

I think of death only with tranquility, as an end. I refuse to let death hamper life. Death must enter life only to define it.

They think of the philosopher as holding the ideal or subjective in one hand and the real or objective in the other and then have him strike the palms of his hands together so that one abrades the other. The product of this abrasion is the Absolute.

The supervision of the state extends to the lock upon the door, and there begins mine own. The lock is the boundary line between the power of the government and my own private power. It is the intention of locks to make possible self-protection. In my own house my person is sacred and inviolable even to the government. In civil cases government has no right to attack me in my house, but must wait till I am upon public ground.

For the moment, the jazz is playing; there is no melody, just notes, a myriad of tiny tremors. The notes know no rest, an inflexible order gives birth to them then destroys them, without ever leaving them the chance to recuperate and exist for themselves.... I would like to hold them back, but I know that, if I succeeded in stopping one, there would only remain in my hand a corrupt and languishing sound. I must accept their death; I must even want that death: I know of few more bitter or intense impressions.

No man must encroach upon my province nor I upon his. He may advise me, moderately and without perniciousness, but he must not expect to dictate to me. He may censure me freely and without reserve but he should remember that I am to act by my deliberation and not his. He may exercise a republican boldness in judging, but he must not be peremptory and imperious in prescribing. Force may never be resorted to but, in the most extraordinary and imperious emergency.

I have tried to set forth a theory that enables us to understand and to assess these feelings about the primacy of justice. Justice as fairness is the outcome: it articulates these opinions and supports their general tendency.

I hold agitation to be essential, not only to the obtaining of good and just measures, but to the existence of a free Government itself. If you choose to adopt the principle of Bishop Horsley, that the people have nothing to do with the laws but to obey them, then, indeed, you may deprecate agitation; but, while we live in a free country, and under a free Government, your deprecation is vain and untenable... I say that the slave-trade would never have been abolished without agitation. I say that slavery would never have been abolished without agitation... What is agitation when it is examined, but the mode in which the people in the great outer assembly debate?

Alas for him who seeks salvation in good only!Balanced on God's strong shoulders, Good and Evil flaptogether like two mighty wings and lift him high.

Live with the gods.

I am not sure but I should betake myself in extremities to the liberal divinities of Greece, rather than to my country's God. Jehovah, though with us he has acquired new attributes, is more absolute and unapproachable, but hardly more divine, than Jove. He is not so much of a gentleman, not so gracious and catholic, he does not exert so intimate and genial an influence on nature, as many a god of the Greeks.

Government must be a transparent garment which tightly clings to the people's body.

In most men, the conscious and the unconscious being hardly ever make contact; consequently the conscious aim is to make himself as comfortable as possible with as little effort as possible. But there are other men, whom we have been calling, for convenience, 'Outsiders', whose conscious and unconscious being keep in closer contact, and the conscious mind is forever aware of the urge to care about 'more abundant life', and care less about comfort and stability and the rest of the notions that are so dear to the bourgeois.

I shall need only myself to be happy.

If literature isn't everything, it's not worth a single hour of someone's trouble.

The aim of art, the aim of a life can only be to increase the sum of freedom and responsibility to be found in every man and in the world. It cannot, under any circumstances, be to reduce or suppress that freedom, even temporarily.

Science may set limits to knowledge, but should not set limits to imagination.

Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation.

Biopiracy is biological theft; illegal collection of indigenous plants by corporations who patent them for their own use.

So far from the posterior lobe, the posterior cornu, and the hippocampus minor, being structures peculiar to and characteristic of man, as they have been over and over again asserted to be, even after the publication of the clearest demonstration of the reverse, it is precisely these structures which are the most marked cerebral characters common to man with the apes. They are among the most distinctly Simian peculiarities which the human organism exhibits.

I feel sure that the police are helping us more than I could do in ten years. They are making more anarchists than the most prominent people connected with the anarchist cause could make in ten years. If they will only continue I shall be very grateful; they will save me lots of work.

If a victory is told in detail, one can no longer distinguish it from a defeat.

We cannot hope to give here a final clarification of the essence of fact, judgement, object, property; this task leads into metaphysical abysses; about these one has to seek advice from men whose name cannot be stated without earning a compassionate smile-e.g.

Americans combine to give fêtes, found seminaries, build churches, distribute books, and send missionaries to the antipodes. Hospitals, prisons, and schools take shape in that way. Finally, if they want to proclaim a truth or propagate some feeling by the encouragement of a great example, they form an association. In every case, at the head of any new undertaking, where in France you would find the government or in England some territorial magnate, in the United States you are sure to find an association. I have come across several types of association in America of which, I confess, I had not previously the slightest conception, and I have often admired the extreme skill they show in proposing a common object for the exertions of very many and in inducing them voluntarily to pursue it.

Every parting gives a foretaste of death, every reunion a hint of the resurrection.

When all these things are lacking there is no culture; there is in the strictest sense of the word, barbarism. And let us not deceive ourselves, this is what is beginning to appear in Europe under the progressive rebellion of the masses. The traveller who arrives in a barbarous country knows that in that territory there are no ruling principles to which it is possible to appeal. Properly speaking, there are no barbarian standards. Barbarism is the absence of standards to which appeal can be made.
