A man of understanding has lost nothing, if he has himself.

Is it always permissible to speak of the extension of a concept, of a class? And if not, how do we recognize the exceptional cases? Can we always infer from the extension of one concept's coinciding with that of a second, that every object which falls under the first concept also falls under the second?

Life is that which is discontent, which struggles and seeks, which suffers and creates.

Christianity set itself the goal of fulfilling man's unattainable desires, but for that very reason ignored his attainable desires. By promising man eternal life, it deprived him of temporal life, by teaching him to trust in God's help it took away his trust in his own powers; by giving him faith in a better life in heaven, it destroyed his faith in a better life on earth and his striving to attain such a life. Christianity gave man what his imagination desires, but for that very reason failed to give him what he really and truly desires.

Social and economic inequalities are to satisfy two conditions: first, they are to be attached to positions and offices open to all under conditions of fair equality of opportunity; and second, they are to be to the greatest benefit to the least-advantaged members of society.

I hate writing. I so intensely hate writing — I cannot tell you how much. The moment I am at the end of one project I have the idea that I didn’t really succeed in telling what I wanted to tell, that I need a new project — it’s an absolute nightmare. But my whole economy of writing is in fact based on an obsessional ritual to avoid the actual act of writing.

In framing scientific terms, the appropriation of old words is preferable to the invention of new ones.

Private property has made us so stupid and one-sided that an object is only ours when we have it - when it exists for us as capital, or when it is directly possessed, eaten, drunk, worn, inhabited, etc., - in short, when it is used by us. Although private property itself again conceives all these direct realizations of possession as means of life, and the life which they serve as means is the life of private property - labour and conversion into capital. In place of all these physical and mental senses there has therefore come the sheer estrangement of all these senses - the sense of having. The human being had to be reduced to this absolute poverty in order that he might yield his inner wealth to the outer world.

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.

Of all passions, that which inclineth men least to break the laws is fear.

Against the diseases of the mind, philosophy provides sufficient antidotes. The instruments which it employs for this purpose are the virtues; the root of which, whence all the rest proceed, is prudence. This virtue comprehends the whole art of living discreetly, justly, and honorably, and is, in fact, the same thing with wisdom. It instructs men to free their understandings from the clouds of prejudice; to exercise temperance and fortitude in the government of themselves: and to practice justice towards others. Although pleasure, or happiness, which is the end of living, be superior to virtue, which is only the means, it is every one's interest to practice all the virtues; for in a happy life, pleasure can never be separated from virtue.

They should always be heard, and fairly and kindly answer'd, when they ask after any thing they would know, and desire to be informed about. Curiosity should be as carefully cherish'd in children, as other appetites suppress'd.

The more we try to wrest ourselves from our ego, the deeper we sink into it.

He lit a lamp in broad daylight and said, as he went about, "I am looking for a human."

The bourgeois public sphere may be conceived above all as the sphere of private people come together as a public; they soon claimed the public sphere regulated from above against the public authorities themselves, to engage them in a debate over the general rules governing relations in the basically privatized but publicly relevant sphere of commodity exchange and social labor.

It might be said to the agitator, "However convinced you were of the justice of your cause and the truth of your convictions, you ought not to have made a public attack upon any man's character until you had examined the evidence on both sides with the utmost patience and care." In the first place, let us admit that, so far as it goes, this view of the case is right and necessary; right, because even when a man's belief is so fixed that he cannot think otherwise, he still has a choice in the action suggested by it, and so cannot escape the duty of investigating on the ground of the strength of his convictions; and necessary, because those who are not yet capable of controlling their feelings and thoughts must have a plain rule dealing with overt acts.

Hegel's philosophy revolved about the universality of reason; it was a rational system with its every part (the subjective as well as the objective spheres) integrated into a comprehensive whole. Marx shows that capitalist society first put such a universality into practice.

"What on earth prompted you to take a hand in this?""I don't know. My... my code of morals, perhaps.""Your code of morals. What code, if I may ask?" "Comprehension."

Providence has already begun the punishment of the guilty; more than sixty regicides, the most guilty among them, have already died a violent death.

The circulation of commodities is the original precondition of the circulation of money.

He who has injured thee was either stronger or weaker than thee. If weaker, spare him; if stronger, spare thyself.

Speciesism is an attitude of prejudice towards beings because they're not members of our species, so just as racism means that you're prejudiced against beings who are not members of your race and sexism means you're prejudiced against people of the other sex. So we humans tend to be speciesist in we think that any being that is a member of the species homo sapien just automatically has a higher moral status and is more important than any being that is a member of any other species, irrespective of the actual characteristics of those beings.

What madness this is, to punish oneself because one is unfortunate, and not to lessen, but to increase one's ills! You ought to display, in this matter also, that decent behaviour and modesty which has characterised all your life: for there is such a thing as self-restraint in grief also.

Then we may begin by assuming that there are three classes of men—lovers of wisdom, lovers of honor, lovers of gain?

The average man's opinions are much less foolish than they would be if he thought for himself: in science, at least, his respect for authority is on the whole beneficial.

Where cruelty and injustice are concerned, hopelessness is submission, which I believe is immoral.

The only non-Christians who seemed to me really to know anything were the Romantics; and a good many of them were dangerously tinged with something like religion, even at times with Christianity. The upshot of it all could nearly be expressed in a perversion of Roland's great line in the Chanson: 'Christians are wrong, but all the rest are bores.'

Those who are humane achieve glory. Those who are inhumane suffer disgrace.

The friend, enemy, and combat concepts receive their real meaning precisely because they refer to the real possibility of physical killing. War follows from enmity. War is the existential negation of the enemy.

I confess I have no great notion of the use of books, except to amuse a railway journey; although, I believe, there are some very exact treatises on astronomy, the use of the globes, agriculture, and the art of making paper flowers. Upon the less apparent provinces of life I fear you will find nothing truthful.

Of all Discourse, governed by desire of Knowledge, there is at last an End, either by attaining, or by giving over.

Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.

Whereas, our tenet ever was, and, indeed, it is almost the only landmark which now divides the federalists from the republicans, that Congress had not unlimited powers to provide for the general welfare, but were restrained to those specifically enumerated;...

Lives matter in the sense that they assume physical form within the sphere of appearance; lives matter because they are to be valued equally.

It takes a long time to bring excellence to maturity.

It's silly to try to escape other people's faults. They are inescapable. Just try to escape your own.

Most of what we strive for in our modern life uses the apparatus of goal seeking that was originally set up to seek goals in the state of nature.

Space, subjectively, is the coexistence of perceptions - perceiving two objects at once.

Jung fiercely resented the implication that he was a hypocritical, self-seeking Judas, a 'rat'. Yet there was just enough truth in it to strike home. He was undoubtedly a man who liked his own way, no matter what the cost to others.

A theologian is born by living, nay dying and being damned, not by thinking, reading, or speculating.

It is rare that the public sentiment decides immorally or unwisely, and the individual who differs from it ought to distrust and examine well his own opinion.

The man that does not know himself not to be at the mercy of other men, that does not feel that he is invulnerable to all the vicissitudes of fortune, is incapable of a constant and inflexible virtue.

Is it reasonable to assume a purposiveness in all the parts of nature and to deny it to the whole?

My own book Women, Race and Class was one of many that were published during that era, including, to name only a few, This Bridge Called My Back, edited by Gloria Anzaldúa and Cherrie Moraga, the work of bell hooks and Michelle Wallace, and the anthology All the Women Are White, All the Blacks Are Men, but Some of Us Are Brave: Black Women's Studies. So behind this concept of intersectionality is a rich history of struggle. A history of conversations among activists within movement formations, and with and among academics as well.

Logic has borrowed, perhaps, the rules of geometry, without comprehending their force... it does not thence follow that they have entered into the spirit of geometry, and I should be greatly averse... to placing them on a level with that science that teaches the true method of directing reason.

O my Father, if this cup may not pass away from me, except I drink it, thy will be done.
