Once it's been proved to you that you're descended from an ape, it's no use pulling a face; just accept it. Once they've proved to you that a single droplet of your own fat must be dearer to you than a hundred thousand of your fellow human beings and consequently that all so-called virtues and duties are nothing but ravings and prejudices, then accept that too, because there's nothing to be done.

My interests drew me in different directions. On the one hand I was powerfully attracted by science, with its truths based on facts; on the other hand I was fascinated by everything to do with comparative religion. [...] In science I missed the factor of meaning; and in religion, that of empiricism.

Do not all theists insist that there can be no morality, no justice, honesty or fidelity without the belief in a Divine Power? Based upon fear and hope, such morality has always been a vile product, imbued partly with self-righteousness, partly with hypocrisy. As to truth, justice, and fidelity, who have been their brave exponents and daring proclaimers? Nearly always the godless ones: the Atheists; they lived, fought, and died for them. They knew that justice, truth, and fidelity are not conditioned in heaven, but that they are related to and interwoven with the tremendous changes going on in the social and material life of the human race; not fixed and eternal, but fluctuating, even as life itself.

The Kropotkins, the Perovskayas, the Breshkovskayas, and hosts of others repudiated wealth and station and refused to serve King Mammon. They went among the people, not to lift them up but themselves to be lifted up, to be instructed, and in return to give themselves wholly to the people. That accounts for the heroism, the art, the literature of Russia, the unity between the people, the mujik and the intellectual. That to some extent explains the literature of all European countries, the fact that the Strindbergs, the Hauptmanns, the Wedekinds, the Brieux, the Mirbeaus, the Steinlins and Rodins have never dissociated themselves from the people.

There are men and gods, and beings like Pythagoras.

The soul was not made to dwell in a thing; and when forced to it, there is no part of that soul but suffers violence.

The entire method consists in the order and arrangement of the things to which the mind's eye must turn so that we can discover some truth.

How can he [today's writer] be honored, when he does not honor himself; when he loses himself in the crowd; when he is no longer the lawgiver, but the sycophant, ducking to the giddy opinion of a reckless public.

I could see clearly that this problem could only be solved on the individual and personal level; political revolt is irrelevant. Both Camus and Sartre had been neatly hog-tied by their earlier radicalism. Camus came to see that rebellion is a political roundabout that revolves back to the same old tyranny; too ashamed to admit that he had outgrown his leftism, he found himself in an intellectual cul-de-sac. Sartre accused Camus of being a reactionary; but he paid for his own refusal to reexamine his political convictions by congealing into a grotesque attitude of permanent indignation, shaking his fist at some abstract Authority. Where politics is concerned, he seemed determined to be guided by his emotions.

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?

...and if you are common, you can dress up as a woman, show you behind or write poems: there's nothing offensive about a naked behind if it's everybody's; each person will be mirrored in it.

May not we then confidently pronounce that man happy who realizes complete goodness in action, and is adequately furnished with external goods? Or should we add, that he must also be destined to go on living not for any casual period but throughout a complete lifetime in the same manner, and to die accordingly, because the future is hidden from us, and we conceive happiness as an end, something utterly and absolutely final and complete? If this is so, we shall pronounce those of the living who possess and are destined to go on possessing the good things we have specified to be supremely blessed, though on the human scale of bliss.

This endeavour to do a thing or leave it undone, solely in order to please men, we call ambition, especially when we so eagerly endeavour to please the vulgar, that we do or omit certain things to our own or another's hurt : in other cases it is generally called kindliness.

Never read any book that is not a year old.

An unjust law is no law at all.

Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.

Job endured everything - until his friends came to comfort him, then he grew impatient.

I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true.

Ideas do not exist separately from language.

The will to the "true world" in the sense of Plato and Christianity ... is in truth a no-saying to our present world, precisely the one in which art is at home.

The progress from an absolute to a limited monarchy, from a limited monarchy to a democracy, is a progress toward a true respect for the individual.

The sensuous may be exceedingly distinct, while intellectual concepts are extremely confused. The former we observe in the prototype of sensuous knowledge geometry; the latter, in the organon of all intellectual concepts, metaphysics. It is evident how much toil the latter is expending to dispel the fogs of confusion darkening the common intellect, though not always with the happy success of the former science.

The severe Schools shall never laugh me out of the Philosophy of Hermes, that this visible world is but a picture of the invisible.

Metaphysical fallacies contain the only clues we have to what thinking means to those who engage in it.

There is no greater impediment to progress in the sciences than the desire to see it take place too quickly.

My hearers, this discourse has not wandered out into the world to look for conflict, it has not tried to get the better of anybody, it has not even tried to uphold anybody, as though there was battle without. It has spoken to you; not by way of explaining anything to you, but trying to speak secretly with you about your relationship to that secret wisdom mentioned in our text. Oh that nothing may upset you in respect to this, “neither life nor death nor things present nor things to come nor any other creature” (Romans 8:38) –not this discourse, which, though it may have profited you nothing, yet has striven for what after all is the first and the last, to help you have what the Scripture calls “faith in yourself before God.

My desire for knowledge is intermittent; but my desire to bathe my head in atmospheres unknown to my feet is perennial and constant. The highest that we can attain to is not Knowledge, but Sympathy with Intelligence. I do not know that this higher knowledge amounts to anything more definite than a novel and grand surprise on a sudden revelation of the insufficiency of all that we called Knowledge before - a discovery that there are more things in heaven and earth than are dreamed of in our philosophy.

I found one day in school a boy of medium size ill-treating a smaller boy. I expostulated, but he replied: "The bigs hit me, so I hit the babies; that's fair." In these words he epitomized the history of the human race.

Once for all, then, a short precept is given thee: Love, and do what thou wilt: whether thou hold thy peace, through love hold thy peace; whether thou cry out, through love cry out; whether thou correct, through love correct; whether thou spare, through love do thou spare: let the root of love be within, of this root can nothing spring but what is good.

Militarism, the destroyer of youth, the raper of women, the annihilator of the best in the race, the very mower of life.

In every man sleeps a prophet, and when he wakes there is a little more evil in the world

Nothing can be produced from nothing.

There are two godheads: the world and my independent I. I am either happy or unhappy, that is all. It can be said: good or evil do not exist. A man who is happy must have no fear. Not even in the face of death. Only a man who lives not in time but in the present is happy.

The general co-operation of all members of society for the purpose of planned exploitation of the forces of production, the expansion of production to the point where it will satisfy the needs of all, the abolition of a situation in which the needs of some are satisfied at the expense of the needs of others, the complete liquidation of classes and their conflicts, the rounded development of the capacities of all members of society through the elimination of the present division of labor, through industrial education, through engaging in varying activities, through the participation by all in the enjoyments produced by all, through the combination of city and country - these are the main consequences of the abolition of private property.

What an incitation to hilarity, hearing the word goal while following a funeral procession!

Should the believers in special creations consider it unfair thus to call upon them to describe how special creations take place, I reply that this is far less than they demand from the supporters of the Development Hypothesis. They are merely asked to point out a conceivable mode. On the other hand, they ask, not simply for a conceivable mode, but for the actual mode.

All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses, his real conditions of life, and his relations with his kind.

Science is a systematic method for studying and working out those generalizations that seem to describe the behavior of the universe. It could exist as a purely intellectual game that would never affect the practical life of human beings either for good or evil, and that was very nearly the case in ancient Greece, for instance. Technology is the application of scientific findings to the tools of everyday life, and that application can be wise or unwise, useful or harmful. Very often, those who govern technological decisions are not scientists and know little about science.

Love is a severe critic. Hate can pardon more than love.

So long as you "have" yourself, have yourself as an object, your experience of man is only as of a thing among things.

The third argument, enclosing and defending the other two, consists in the development of those principles of logic according to which the humble argument is the first stage of a scientific inquiry into the origin of the three Universes, but of an inquiry which produces, not merely scientific belief, which is always provisional, but also a living, practical belief, logically justified in crossing the Rubicon with all the freightage of eternity.

The secret is that only that which can destroy itself is truly alive.

Nothing is so difficult as not deceiving oneself.

Of all the cultural aspects of humanity, the only one which is not broken up into national or regional splinters is science. Different nations have different languages, they may have different religions, may have different dietaries, may have different holidays, different ways of thinking, but here's only one science. 

In spite of the universalistic spirit of the monotheistic Western religions and of the progressive political concepts that are expressed in the idea "that all men are created equal," love for mankind has not become a common experience. Love for mankind is looked upon as an achievement which, at best, follows love for an individual or as an abstract concept to be realized only in the future. But love for man cannot be separated from love for one individual. To love one person productively means to be related to his human core, to him as representing mankind. Love for one individual, in so far as it is divorced from love for man, can refer only to the superficial and to the accidental; of necessity it remains shallow.

But our Don Quixote, the inward, the immortal Don Quixote, conscious of his own comicness, does not believe that his doctrines will triumph in this world, because they are not of it. And it is better that they should not triumph. And if the world wished to make Don Quixote king, he would retire alone to the mountain, fleeing from the king-making crowds, as Christ retired alone to the mountain when, after the miracle of the loaves and fishes, they sought to proclaim him king. He left the title of king for the inscription written over the cross.

Disturbances in society are never more fearful than when those who are stirring up the trouble can use the pretext of religion to mask their true designs.

An intellectual is a person who has discovered something more interesting than sex.

Wise people are in want of nothing, and yet need many things. On the other hand, nothing is needed by fools, for they do not understand how to use anything, but are in want of everything.

To be happy, we must not be too concerned with others.
