To Xeniades, who had purchased Diogenes at the slave market, he said, "Come, see that you obey orders."

I have known only one person in my life who claimed to have seen a ghost. It was a woman; and the interesting thing is that she disbelieved in the immortality of the soul before seeing the ghost and still disbelieves after having seen it. She thinks it was a hallucination. In other words, seeing is not believing. This is the first thing to get clear in talking about miracles.

I cannot conceive how any man can have brought himself to that pitch of presumption, to consider his country as nothing but carte blanche, upon which he may scribble whatever he pleases.

Someone in despair despairs over something. So, for a moment, it seems, but only for a moment. That same instant the true despair shows itself, or despair in its true guise. In despairing over something he was really despairing over himself, and he wants now to be rid of himself.

All abstract sciences are nothing but the study of relations between signs.

As to the objection that these rules are common in the world, that it is necessary to define every thing and to prove every thing, and that logicians themselves have placed them among their art, I would that the thing were true and that it were so well known... But so little is this the case, that, geometricians alone excepted, who are so few in number that they are a single in a whole nation and long periods of time, we see no others that know it.

Allow me, Gentlemen, to pose this question in a more serious manner. Do I need to tell you that it is not a question at first of the natural, physiological, ethnographic difference that exists between individuals, but of the social difference, that is produced by the economic organization of society? Give to all the children, from their birth, the same means of maintenance, education, and instruction; give then to all the men thus raised the same social milieu, the same means of earning their living by their own labor, and you will see then that many of these differences, that we believe to be natural differences, will disappear because they are nothing but the effect of an unequal division of the conditions of intellectual and physical development - of the conditions of life.

If a workman can conveniently spare those three halfpence, he buys a pot of porter. If he cannot, he contents himself with a pint, and, as a penny saved is a penny got, he thus gains a farthing by his temperance.

So long as man remains free he strives for nothing so incessantly and so painfully as to find someone to worship. But man seeks to worship what is established beyond dispute, so that all men would agree at once to worship it. For these pitiful creatures are concerned not only to find what one or the other can worship, but to find community of worship is the chief misery of every man individually and of all humanity from the beginning of time. For the sake of common worship they've slain each other with the sword. They have set up gods and challenged one another, 'Put away your gods and come and worship ours, or we will kill you and your gods!' And so it will be to the end of the world, even when gods disappear from the earth; they will fall down before idols just the same.

To try curing someone of a "vice," of what is the deepest thing he has, is to attack his very being, and this is indeed how he himself understands it, since he will never forgive you for wanting him to destroy himself in your way and not his.

He believes in that mummery a good deal less than I do, and I don't believe in it at all.

For anyone who is alone, without God and without a master, the weight of days is dreadful. Hence one must choose a master, God being out of style.

The Catholic solution of our problem, of our unique vital problem, the problem of the immortality and eternal salvation of the soul, satisfies the will, and therefore satisfies life; but the attempt to rationalize it by means of a dogmatic theology fails to satisfy the reason. And reason has its exigencies as imperious as those of life. It is no use seeking to force ourselves to consider as super-rational what clearly appears to us to be contra-rational... Infallibility, a notion of Hellenic origin, is in its essence a rationalistic category.

When contemporary feminist movement first began, feminist writings and scholarship by black women was groundbreaking. The writings of black women like Cellestine Ware, Toni Cade Bambara, Michele Wallace, Barbara Smith, and Angela Davis, to name a few, were all works that sought to articulate, define, speak to and against the glaring omissions in feminist work, the erasure of black female presence.

It is natural for us to seek a Standard of Taste; a rule, by which the various sentiments of men may be reconciled; at least, a decision, afforded, confirming one sentiment, and condemning another.

Alonso of Aragon was wont to say in commendation of age, that age appears to be best in four things - old wood best to burn, old wine to drink, old friends to trust, and old authors to read.

It is now generally accepted that the roots of our ethics lie in patterns of behavior that evolved among our pre-human ancestors, the social mammals and that we retain within our biological nature elements of these evolved responses. We have learned considerably more about these responses, and we are beginning to to understand how they interact with our capacity to reason.

The education of the child must accord both in mode and arrangement with the education of mankind, considered historically. In other words, the genesis of knowledge in the individual, must follow the same course as the genesis of knowledge in the race. In strictness, this principle may be considered as already expressed by implication; since both being processes of evolution, must conform to those same general laws of evolution... and must therefore agree with each other. Nevertheless this particular parallelism is of value for the specific guidance it affords. To M. Comte we believe society owes the enunciation of it; and we may accept this item of his philosophy without at all committing ourselves to the rest.

I have never in my life met a man like him for noble simplicity, and boundless truthfulness. I understood from the way he talked that anyone who chose could deceive him, and that he would forgive anyone afterwards who had deceived him, and that was why I grew to love him.

If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over.

But yet they that have no Science, are in better, and nobler condition with their naturall Prudence; than men, that by their mis-reasoning, or by trusting them that reason wrong, fall upon false and absurd generall rules.

Let me suggest a theme for you: to state to yourself precisely and completely what that walk over the mountains amounted to for you, - returning to this essay again and again, until you are satisfied that all that was important in your experience is in it. Give this good reason to yourself for having gone over the mountains, for mankind is ever going over a mountain. Don't suppose that you can tell it precisely the first dozen times you try, but at 'em again, especially when, after a sufficient pause, you suspect that you are touching the heart or summit of the matter, reiterate your blows there, and account for the mountain to yourself. Not that the story need be long, but it will take a long while to make it short.

Where knowledge is a duty, ignorance is a crime. 

I quite understand the principle of confining employment as far as possible to the British without regard for efficiency. I think, however, that the Ministry is not applying the principle sufficiently widely. I know many Englishmen who have married foreigners, and many English potential wives who are out of a job. Would not a year be long enough to train an English wife to replace the existing foreign one in such cases?

One cannot ignore half of life for the purposes of science, and then claim that the results of science give a full and adequate picture of the meaning of life. All discussions of 'life' which begin with a description of man's place on a speck of matter in space, in an endless evolutionary scale, are bound to be half-measures, because they leave out most of the experiences which are important to use as human beings.

Reading the morning newspaper is the realist's morning prayer. One orients one's attitude toward the world either by God or by what the world is. The former gives as much security as the latter, in that one knows how one stands.

I am condemned to be free.

In the state of nature, Profit is the measure of Right.

Science is the knowledge of Consequences, and dependence of one fact upon another: by which, out of that we can presently do, we know how to do something else when we will, or the like, another time.

Upstart greatness is everywhere less respected than ancient greatness.

The skepticism which fails to contribute to the ruin of our health is merely an intellectual exercise.

From such honor and such a height of fortune am I, thus fallen to earth, cast down amongst mortals.

The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration: this may be called perfect virtue.

There is a plague on Man, the opinion that he knows something.

The question of the principle of the form of the intelligible world turns, therefore, upon making apparent in what manner it is possible for several substances to be in mutual commerce, and for this reason to pertain to the same whole, which is called world. We do not here consider the world, let it be understood, as to matter, that is, as to the nature of the substances of which it consists, whether they be material or immaterial, but as to form, that is to say, how among several things taken separately a connection, and among them all, totality can have place.

Who is this that cries from the ends of the earth? Who is this one man who reaches to the extremities of the universe? He is one, but that one is unity. He is one, not one in a single place, but the cry of this one man comes from the remotest ends of the earth. But how can this one man cry out from the ends of the earth, unless he be one in all?

I was still blind, but twinkling stars did dance Throughout my being's limitless expanse, Nothing had yet drawn close, only at distant stages I found myself, a mere suggestion sensed in past and future ages.

Cure the drunkard, heal the insane, mollify the homicide, civilize the Pawnee, but what lessons can be devised for the debaucher of sentiment?

...the Outsider's problem is the problem of denial of self-expression.

Operational analysis ... cannot raise the decisive question whether the consent itself was not the work of manipulation-a question for which the actual state of affairs provides ample justification. The analysis cannot raise it because it would transcend its terms toward transitive meaning-toward a concept of democracy which would reveal the democratic election as a rather limited democratic process. Precisely such a non-operational concept is the one rejected by the authors as "unrealistic" because it defines democracy on too articulate a level as the clear-cut control of representation by the electorate-popular control as popular sovereignty.

Autumn is a second Spring when every leaf is a flower.

Age imprints more wrinkles in the mind than it does on the face.

The aphorism is cultivated only by those who have known fear in the midst of words, that fear of collapsing with all the words.

Pettiness separates; breadth unites. Let us be broad and big. Let us not overlook vital things because of the bulk of trifles confronting us. A true conception of the relation of the sexes will not admit of conqueror and conquered; it knows of but one great thing: to give of one's self boundlessly, in order to find one's self richer, deeper, better. That alone can fill the emptiness, and transform the tragedy of woman's emancipation into joy, limitless joy.

If you want to be respected by others the great thing is to respect yourself. Only by that, only by self-respect will you compel others to respect you.

Abstain from animals.

Is it just I who cannot found a school, or can a philosopher never do so?

Every revolutionary ends as an oppressor or a heretic.
