If all men, by the act of being born, are destined to suffer violence, that is a truth to which the empire of circumstances closes their minds.

The Interpretation of the Laws of Nature in a Common-wealth, dependeth not on the books of Moral Philosophy. The Authority of writers, without the Authority of the Commonwealth, maketh not their opinions Law, be they never so true.

He who has never envied the vegetable has missed the human drama. 

It is necessary to show that there is nothing so little known [as the above rules], nothing more difficult to practice, or nothing more useful and universal.

Apart from autograph hunters, I get... many letters from Hindus, beseeching me to adopt some form of mysticism, from young Americans, asking me where I think the line should be drawn in petting, and from Poles, urging me to admit that while all other nationalism may be bad that of Poland is wholly noble. I get letters from engineers who cannot understand Einstein, and from parsons who think that I cannot understand Genesis, from husbands whose wives have deserted them - not (they say) that that would matter, but the wives have taken the furniture with them, and what in these circumstances should an enlightened male do? ...I get letters (concerning whose genuineness I am suspicious) trying to get me to advocate abortion, and I get letters from young mothers asking my opinion of bottle-feeding.

To love truth for truth's sake is the principal part of human perfection in this world, and the seed-plot of all other virtues.

Nature paints the best part of a picture, carves the best parts of the statue, builds the best part of the house, and speaks the best part of the oration.

To romanticize the world is to make us aware of the magic, mystery and wonder of the world; it is to educate the senses to see the ordinary as extraordinary, the familiar as strange, the mundane as sacred, the finite as infinite.

If the thought enunciates an object as a truth, it is only as a challenge to this object's own self-fulfillment.

The late philosopher Morris R. Cohen of CCNY was asked by a student in the metaphysics course, "Professor Cohen, how do I know that I exist?" The keen old prof replied, "And who is asking?"

If the brutes have consciousness and no souls, then it is clear that, in them, consciousness is a direct function of material changes; while, if they possess immaterial subjects of consciousness, or souls, then, as consciousness is brought into existence only as the consequence of molecular motion of the brain, it follows that it is an indirect product of material changes. The soul stands related to the body as the bell of a clock to the works, and consciousness answers to the sound which the bell gives out when it is struck.

The sin of pride may be a small or a great thing in someone's life, and hurt vanity a passing pinprick or a self-destroying or even murderous obsession. Possibly, more people kill themselves and others out of hurt vanity than out of envy, jealousy, malice or desire for revenge.

The goal of maximizing the welfare of all may be better achieved by an ethic that accepts our inclinations and harnesses them so that, taken as a whole, the system works to everyone's advantage.

Learn to see in another's calamity the ills which you should avoid.

After all, in the poets love has its priests, and sometimes one hears a voice which knows how to defend it; but of faith one hears never a word. Who speaks in honor of this passion? Philosophy goes further. Theology sits rouged at the window and courts its favor, offering to sell her charms to philosophy. it is supposed to be difficult to understand Hegel, but to understand Abraham is a trifle. To go beyond Hegel's is a miracle, but to get beyond Abraham is the easiest thing of all.

Poverty is the lack of many things, but avarice is the lack of all things.

The retinue of a grandee in China or Indostan accordingly is, by all accounts, much more numerous and splendid than that of the richest subjects of Europe.

The sphere of consciousness shrinks in action; no one who acts can lay claim to the universal, for to act is to cling to the properties of being at the expense of being itself, to form a reality to reality's detriment.

In the ceremonies of the public execution, the main character was the people, whose real and immediate presence was required for the performance.

A people that sells its own children is more condemnable than the buyer; this commerce demonstrates our superiority; he who gives himself a master was born to have one.

Try to be free: you will die of hunger.

Treat your friend as if he might become an enemy.

The "second sight" possessed by the Highlanders in Scotland is actually a foreknowledge of future events. I believe they possess this gift because they don't wear trousers... That is also why in all countries women are more prone to utter prophecies.

The animals are much more content with mere existence than we are; the plants are wholly so; and man is so according to how dull and insensitive he is. The animal's life consequently contains less suffering but also less pleasure than the human's, the direct reason being that on the one hand it is free from care and anxiety and the torments that attend them, but on the other is without hope and therefore has no share in that anticipation of a happy future which, together with the enchanting products of the imagination which accompany it, is the source of most of our greatest joys and pleasures. The animal lacks both anxiety and hope because its consciousness is restricted to what is clearly evident and thus to the present moment: the animal is the present incarnate.

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.

If one does not understand a person, one tends to regard him as a fool.

Happily for poor traduced and degraded human nature, the principle for which we now content will speedily divest it of all the ridiculous and absurd mystery with which it has been hitherto enveloped by the ignorance of preceding times: and all the ''complicated'' and ''counteracting'' motives for good conduct, which have been multiplied almost to infinity, will be reduced to ''one single principle of action'', which, by its evident operation and sufficiency, shall render this intricate system ''unnecessary'', and ultimately supersede it in all parts of the earth. That principle is THE HAPPINESS OF SELF CLEARLY UNDERSTOOD AND UNIFORMLY PRACTICED; WHICH CAN ONLY BE ATTAINED BY CONDUCT THAT MUST PROMOTE THE HAPPINESS OF THE COMMUNITY.

We mustn't forget how quickly the visions of genius become the canned goods of intellectuals.

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.

You wanted God's ideas about what was best for you to coincide with your ideas, but you also wanted him to be the almighty Creator of heaven and earth so that he could properly fulfill your wish. And yet, if he were to share your ideas, he would cease to be the almighty Father.

This species works intentionally on its own destruction (by war). This, however, does not keep the rational creatures of such a constantly advancing culture, even in the midst of war, from promising to mankind in coming centuries an unequivocal prospect of bliss which will never end.

To confuse our own constructions and inventions with eternal laws or divine decrees is one of the most fatal delusions of men. 

I think that when friendship and perception of kinship ruled everything, no one killed any creature, because people thought the other animals were related to them.

Only the truth and its expression can establish that new public opinion which will reform the ancient obsolete and pernicious order of life; and yet we not only do not express the truth we know, but often even distinctly give expression to what we ourselves regard as false. If only free men would not rely on that which has no power, and is always fettered - upon external aids; but would trust in that which is always powerful and free - the truth and its expression!

When I was a student I was assigned "Mythologies" and "A Lover's Discourse," by Roland Barthes, and felt at once that something momentous had happened to me, that I had met a writer who had changed my course in life somehow; and looking back now, I think he did.

The monopoly of capital becomes a fetter upon the mode of production, which has sprung up and flourished along with, and under it. Centralisation of the means of production and socialisation of labour at last reach a point where they become incompatible with their capitalist integument. This integument is burst asunder. The knell of capitalist private property sounds. The expropriators are expropriated.

Nothing like a little judicious levity.

I have in this treatise followed the mathematical method, if not with all strictness, at least imitatively, not in order, by a display of profundity, to procure a better reception for it, but because I believe such a system to be quite capable of it, and that perfection may in time be obtained by a cleverer hand, if stimulated by this sketch, mathematical investigators of nature should find it not unimportant to treat the metaphysical portion, which anyway cannot be got rid of, as a special fundamental department of general physics, and to bring it into unison with the mathematical doctrine of motion.

Intolerance is the besetting sin of moral fervour.

The world is all a carcass and vanity, The shadow of a shadow, a play And in one word, just nothing.

Natural inclinations are present in things from God, who moves all things. So it is impossible for the natural inclinations of a species to be toward evil in itself. But there is in all perfect animals a natural inclination toward carnal union. Therefore it is impossible for carnal union to be evil in itself.

Other curious and rather ominous consequences of war are the increased anti-Semitism which one meets in all classes, particularly the common people, and the strong recrudescence of anti-negro passions in the South. The first is due to the age-old dislike of a monied, influential and pushing minority, coupled with a special grudge against the Jews as being chiefly instrumental, in public opinion, in getting America into the war.

Has not authority from time immemorial stamped every step of progress as treasonable?

Not from fear but from a sense of duty refrain from your sins.

Good and evil, reward and punishment, are the only motives to a rational creature: these are the spur and reins whereby all mankind are set on work, and guided.

To require that a so-called layman should not use his own reason in religious matters, particularly since religion is to be appreciated as moral, but instead follow the appointed clergyman and thus someone else's reason, is an unjust demand because as to morals every man must account for all his doings. The clergyman will not and even cannot assume such a responsibility.

The laws of Rome had wisely divided public power among a large number of magistracies, which supported, checked and tempered each other. Since they all had only limited power, every citizen was qualified for them, and the people - seeing many persons pass before them one after the other - did not grow accustomed to any in particular. But in these times the system of the republic changed. Through the people the most powerful men gave themselves extraordinary commissions - which destroyed the authority of the people and magistrates, and placed all great matters in the hands of one man, or a few.

I am in no way facetious, nor disposed for the mirth and galliardize of company, yet in one dream I can compose a whole Comedy, behold the action, apprehend the jests, and laugh myself awake at the conceits thereof.
