With our present industrial technique we can, if we choose, provide a tolerable subsistence for everybody. We could also secure that the world's population should be stationary if we were not prevented by the political influence of churches which prefer war, pestilence, and famine to contraception. The knowledge exists by which universal happiness can be secured; the chief obstacle to its utilization for that purpose is the teaching of religion. Religion prevents our children from having a rational education; religion prevents us from removing fundamental causes of war; religion prevents us from teaching the ethic of scientific co-operation in place of the old fierce doctrines of sin and punishment. It is possible that mankind is on the threshold of a golden age; but, if so, it will be necessary first to slay the dragon that guards the door, and this dragon is religion.

Wise command, wise obedience: the capability of these two is the net measure of culture, and human virtue, in every man; all good lies in the possession of these two capabilities; all evil, wretchedness and ill-success in the want of these.

Man is as much a slave to his immediate surroundings now as he was when he lived in tree-huts. Give him the highest, the most exciting thoughts about man's place in the universe, the meaning of history; they can all be snuffed out in a moment if he wants his dinner, or feels irritated by a child squalling on a bus. He is bound by pettiness.

Every man is, no doubt, by nature, first and principally recommended to his own care; and as he is fitter to take care of himself than of any other person, it is fit and right that it should be so.

It is not because men's desires are strong that they act ill; it is because their consciences are weak.

The superior man has three things in which he delights, and to be ruler over the kingdom is not one of them. That his father and mother are both alive, and that the condition of his brothers affords no cause for anxiety;-this is one delight. That, when looking up, he has no occasion for shame before Heaven, and, below, he has no occasion to blush before men;-this is a second delight. That he can get from the whole kingdom the most talented individuals, and teach and nourish them;-this is the third delight.

America had declared war with Spain.... It did not require much political wisdom to see that America's concern was a matter of sugar and had nothing to do with humanitarian feelings. Of course there were plenty of credulous people, not only in the country at large, but even in liberal ranks, who believed in America's claim. I could not join them. I was sure that no one, be it individual or government, engaged in enslaving and exploiting at home, could have the integrity or the desire to free people in other lands.

Camus said there is only really one serious philosophical question, which is whether or not to commit suicide. I think there are four or five serious philosophical questions: The first one is: Who started it? The second is: Are we going to make it? The third is: Where are we going to put it? The fourth is: Who's going to clean up? And the fifth: Is it serious?

It is better to conceal ignorance than to expose it.

If the individual were no longer compelled to prove himself on the market, as a free economic subject, the disappearance of this kind of freedom would be one of the greatest achievements of civilization. The technological processes of mechanization and standardization might release individual energy into a yet uncharted realm of freedom beyond necessity. The very structure of human existence would be altered; the individual would be liberated from the work world's imposing upon him alien needs and alien possibilities. The individual would be free to exert autonomy over a life that would be his own.

By simply moving information and brushing information against information, any medium whatever creates vast wealth.

Regarded anatomically, the resemblances between the foot of Man and the foot of the Gorilla are far more striking and important than the differences. ...be the differences between the hand and foot of Man and those of the Gorilla what they may-the differences between those of the Gorilla and those of the lower Apes are much greater.

A critique is not a matter of saying that things are not right as they are. It is a matter of pointing out on what kinds of assumptions, what kinds of familiar, unchallenged, unconsidered modes of thought the practices that we accept rest.

There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. There is no logically necessary connection between events at different times; therefore nothing that is happening now or will happen in the future can disprove the hypothesis that the world began five minutes ago.

How are we to adjudicate among rival ontologies? Certainly the answer is not provided by the semantical formula "To be is to be the value of a variable"; this formula serves rather, conversely, in testing the conformity of a given remark or doctrine to a prior ontological standard.

It is the good children, Madame, who make the most terrible revolutionaries. They say nothing, they do not hide under the table, they eat only one sweet at a time, but later on, they make Society pay dearly for it!

If a person tells me he has been to the worst places I have no reason to judge him; but if he tells me it was his superior wisdom that enabled him to go there, then I know he is a fraud.

I bequeath my soul to God (...). My body to be buried obscurely. For my name and memory, I leave it to men's charitable speeches, and to foreign nations, and the next age.

What potent blood hath modest May!

Diogenes, in his mud-covered sandals, tramps over the carpets of Aristippus. The cynic pullulated at every corner, and in the highest places. This cynic did nothing but saboter the civilisation of the time. He was the nihilist of Hellenism. He created nothing, he made nothing. His role was to undo - or rather to attempt to undo, for he did not succeed in his purpose. The cynic, a parasite of civilisation, lives by denying it, for the very reason that he is convinced that it will not fail. What would become of the cynic among a savage people where everyone, naturally and quite seriously, fulfils what the cynic farcically considers to be his personal role?

The Greeks made Space the subject-matter of a science of supreme simplicity and certainty. and certainty Out of it grew, in the mind of classical antiquity, the idea of pure science. Geometry became one of the most powerful expressions of that sovereignty of the intellect that inspired the thought of those times. At a later epoch, when the intellectual despotism of the Church... had crumbled, and a wave of scepticism threatened to sweep away all that had seemed most fixed, those who believed in Truth clung to Geometry as to a rock, and it was the highest ideal of every scientist to carry on his science "more geometrico". Matter... could be measured as a quantity and... its characteristic expression as a substance was the Law of Conservation of Matter... This, which has hitherto represented our knowledge of space and matter, and which was in many quarters claimed by philosophers as a priori knowledge, absolutely general and necessary, stands to-day a tottering structure.

As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a conclusive argument by which one prove that there is not a God. On the other hand, if I am to convey the right impression to the ordinary man in the street I think that I ought to say that I am an Atheist, because, when I say that I cannot prove that there is not a God, I ought to add equally that I cannot prove that there are not the Homeric gods.

I was still "at the church door". Yet in belief, in the clarification of my philosophy, I had taken an important step. I no longer wavered between alternative views of the world, to be put on or taken off like alternative plays at the theatre. I now saw that there was only one possible play, the actual history of nature and of mankind, although there might well be ghosts among the characters and soliloquies among the speeches. Religions, all religions, and idealistic philosophies, all idealistic philosophies, were the soliloquies and the ghosts. They might be eloquent and profound. Like Hamlet's soliloquy they might be excellent reflective criticisms of the play as a whole. Nevertheless they were only parts of it, and their value as criticisms lay entirely in their fidelity to the facts, and to the sentiments which those facts aroused in the critic.

The gods had condemned Sisyphus to ceaselessly rolling a rock to the top of a mountain, whence the stone would fall back of its own weight. They had thought with some reason that there is no more dreadful punishment than futile and hopeless labor.

The human understanding is moved by those things most which strike and enter the mind simultaneously and suddenly, and so fill the imagination; and then it feigns and supposes all other things to be somehow, though it cannot see how, similar to those few things by which it is surrounded.

I thought that the only action a man could perform without shame was to take his life; that he had no right to diminish himself in the succession of days and the inertic of misery. No elect, I kept telling myself, but those who committed suicide.

In that very hour he became overjoyed in the holy spirit and said: “I publicly praise you, Father, Lord of heaven and earth, because you have carefully hidden these things from wise and intellectual ones and have revealed them to young children. Yes, O Father, because this is the way you approved.

I'll know how to die with courage; that is easier than living.

Scientists, animated by the purpose of proving they are purposeless, constitute an interesting subject for study.

I don't believe you until you tell me, do you really believe, for example, if they say they are Catholic, "Do you really believe that when a priest blesses a wafer, it turns into the body of Christ? Are you seriously telling me you believe that? Are you seriously saying that wine turns into blood?" Mock them. Ridicule them. In public. Don't fall for the convention that we're all too polite to talk about religion. Religion is not off the table. Religion is not off limits. Religion makes specific claims about the universe which need to be substantiated and need to be challenged and, if necessary, need to be ridiculed with contempt.

René Descartes is more widely known as a philosopher than as a mathematician, although his philosophy has been controverted while his mathematics has not. ...In accordance with the ideals of his age, when experimental science was first seriously challenging arrogant speculation, Descartes set a greater store by his philosophy than his mathematics. But he fully appreciated the power of his new method in geometry.

The best work is not what is most difficult for you; it is what you do best.

Opinion is the companion of probability within the medieval epistemology.

The trade of insurance gives great security to the fortunes of private people, and by dividing among a great many that loss which would ruin an individual, makes it fall light and easy upon the whole society.

Don't think money does everything or you are going to end up doing everything for money.

To keep our eyes open longer were but to set our Antipodes. The Huntsmen are up in America, and they are already past their first sleep in Persia. But who can be drowsy at that hour which freed us from everlasting sleep? or have slumbering thoughts at that time, when sleep itself must end, and as some conjecture all shall awake again?

Classical political economy nearly touches the true relation of things, without, however,consciously formulating it. This it cannot so long as it sticks in its bourgeois skin.

He yawned. He had finished the day and he had also finished with his youth. Various well-bred moralities had already discreetly offered him their services: disillusioned epicureanism, smiling tolerance, resignation, common sense stoicism - all the aids whereby a man may savour, minute by minute, like a connoisseur, the failure of a life.

Unlike the masses, intellectuals have a taste for rationality and an interest in facts.

It is the duty of every man, so far as his ability extends, to detect and expose delusion and error.

Man is fulfilled only when he ceases to be man.

Either be silent or say something better than silence.

That which parents should take care of... is to distinguish between the wants of fancy, and those of nature.

This miracle of analysis, this marvel of the world of ideas, an almost amphibian object between Being and Non-being that we call the imaginary number.

In conclusion, I wish to say that my attitude to the whole tragic question is not dictated by my Jewish antecedents. It is motivated by my abhorrence of injustice, and man's inhumanity to man. It is because of this that I have fought all my life for anarchism which alone will do away with the horrors of the capitalist régime and place all races and peoples, including the Jews, on a free and equal basis. Until then I consider it highly inconsistent for socialists and anarchists to discriminate in any shape or form against the Jews.

Is it conceivable to adhere to a religion founded by someone else?

A man of Intellect, of real and not sham Intellect, is by the nature of him likewise inevitably a man of nobleness, a man of courage, rectitude, pious strength; who, even because he is and has been loyal to the Laws of this Universe, is initiated into discernment of the same; to this hour a Missioned of Heaven; whom if men follow, it will be well with them; whom if men do not follow, it will not be well. Human Intellect, if you consider it well, is the exact summary of Human Worth; and the essence of all worth-ships and worships is reverence for that same.
