Always take the short cut; and that is the rational one. Therefore say and do everything according to soundest reason.

I think, therefore I am.

Believing with you that religion is a matter which lies solely between man and his God, that he owes account to none other for his faith or his worship, that the legislative powers of government reach actions only, and not opinions, I contemplate with sovereign reverence that act of the whole American people which declared that their legislature should "make no law respecting an establishment of religion, or prohibiting the free exercise thereof," thus building a wall of separation between church and State.

Understanding being nothing else, but conception caused by Speech.

Do not allow your dreams of a beautiful world to lure you away from the claims of men who suffer here and now.

What does love look like? It has the hands to help others. It has the feet to hasten to the poor and needy. It has eyes to see misery and want. It has the ears to hear the sighs and sorrows of men. That is what love looks like.

Talking nonsense is man's only privilege that distinguishes him from all other organisms.

In all persuasions the bigots are persecutors; the men of a cool and reasonable piety are favourers of toleration; because the former sort of men not taking the pains to be acquainted with the grounds of their adversaries tenets, conceive them to be so absurd and monstrous, that no man of sense can give into them in good earnest. For which reason they are convinced that some oblique bad motive induces them to pretend to the belief of such doctrines, and to the maintaining of them with obstinacy. This is a very general principle in all religious differences, and it is the corner stone of all persecution.

As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.

Our liberty depends on the freedom of the press, and that cannot be limited without being lost.

The universe is the bible of a true Theophilanthropist. It is there that he reads of God. It is there that the proofs of his existence are to be sought and to be found. As to written or printed books, by whatever name they are called, they are the works of man's hands, and carry no evidence in themselves that God is the author of any of them. It must be in something that man could not make, that we must seek evidence for our belief, and that something is the universe; the true bible; the inimitable word, of God.

I am an American, Chicago born - Chicago, that somber city - and go at things as I have taught myself, free-style, and will make the record in my own way: first to knock, first admitted; sometimes an innocent knock, sometimes a not so innocent.

Being summoned by the Athenians out of Sicily to plead for his life, Alcibiades absconded, saying that that criminal was a fool who studied a defence when he might fly for it.

A clever child brought up with a foolish one can itself become foolish. Man is so perfectable and corruptible he can become a fool through good sense.

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.

About fame... Just as the sand-dunes, heaped one upon another, hide each the first, so in life the former deeds are quickly hidden by those that follow after.

Of how much more passion than reason has Jupiter composed us? putting in, as one would say, "scarce half an ounce to a pound."

But to return to the Jewish question. Other groups and nations cultivate their individual traditions. There is no reason why we should sacrifice ours. Standardization robs life of its spice. To deprive every ethnic group of its special traditions is to convert the world into a huge Ford plant. I believe in standardizing automobiles. I do not believe in standardizing human beings. Standardization is a great peril which threatens American culture.

Know that death comes to everyone, and that wealth will sometimes be acquired, sometimes lost. Whatever griefs mortals suffer by divine chance, whatever destiny you have, endure it and do not complain. But it is right to improve it as much as you can, and remember this: Fate does not give very many of these griefs to good people.

The same energy of character which renders a man a daring villain would have rendered him useful to society, had that society been well organized.

It was Rudolf Carnap's dream for the last three decades of his life to show that science proceeds by a formal syntactic method; today no one to my knowledge holds out any hope for that project.

Flimsy, desultory readers, who fly from foolish book to foolish book, and get good of none, and mischief of all-are not these as foolish, unhealthy eaters, who mistake their superficial false desire after spiceries and confectioneries for their real appetite, of which even they are not destitute, though it lies far deeper, far quieter, after solid nutritive food?

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.

The political program of nation building in countries like Afghanistan and Iraq is one central example of the productive project of biopower and war. Nothing could be more postmodernist and antiessentialist than this notion of nation building.

The first-beginnings of things cannot be seen by the eyes.

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.

The sensate body possesses an art of interrogating the sensible according to its own wishes, an inspired exegesis The Visible and the Invisible, trans.

Today the theory of evolution is about as much open to doubt as the theory that the earth goes round the sun, but the full implications of Darwin's revolution have yet to be widely realized.

Never read any book that is not a year old.

There has been progress in design, but not progress in accomplishment.

I thanke God for my happy Dreams|dreames, as I doe for my good rest, for there is a satisfaction in them unto reasonable desires, and such as can be content with a fit of happinesse; and surely it is not a melancholy conceite to thinke we are all asleepe in this world, and that the conceits of this life are as meare dreames to those of the next, as the Phantasmes of the night, to the conceit of the day. There is an equall delusion in both, and the one doth but seeme to bee the embleme or picture of the other;

What a judgment upon the living, if it is true, as has been maintained, that what dies has never existed!

It is useless to try to adjudicate a long-standing animosity by asking who started it or who is the most wrong. The only sufficient answer is to give up the animosity and try forgiveness, to try to love our enemies and to talk to them and (if we pray) to pray for them. If we can't do any of that, then we must begin again by trying to imagine our enemies' children who, like our children, are in mortal danger because of enmity that they did not cause.

The mistake made by all previous systems of ethics has been the failure to recognize that life as such is the mysterious value with which they have to deal. All spiritual life meets us within natural life. Reverence for life, therefore, is applied to natural life and spiritual life alike. In the parable of Jesus, the shepherd saves not merely the soul of the lost sheep but the whole animal. The stronger the reverence for natural life, the stronger grows also that for spiritual life.

...there are more things to admire in men than to despise.

Sometimes one pays most for the things one gets for nothing.

With other beliefs crumbling, many seek to return to what they piously describe as "Enlightenment values". But these values were not as unambiguously benign as is nowadays commonly supposed.

People are often reproached because their desires are directed mainly to money and they are fonder of it than of anything else. Yet it is natural and even inevitable for them to love that which, as an untiring Proteus, is ready at any moment to convert itself into the particular object of our fickle desires and manifold needs. Thus every other blessing can satisfy only one desire and one need; for instance, food is good only to the hungry, wine only for the healthy, medicine for the sick, a fur coat for winter, women for youth, and so on. Consequently, all these are only ... relatively good. Money alone is the absolutely good thing because it meets not merely one need in concreto, but needs generally in abstracto.

Even purely intellectual progress brings about its revenges. Problems settled in a rough and ready way by rude men, absorbed in action, demand renewed attention and show themselves to be still unread riddles when men have time to think. The beneficent demon, doubt, whose name is Legion and who dwells amongst the tombs of old faiths, enters into mankind and thenceforth refuses to be cast out. Sacred customs, venerable dooms of ancestral wisdom, hallowed by tradition and professing to hold good for all time, are put to the question. Cultured reflection asks for their credentials; judges them by its own standards; finally, gathers those of which it approves into ethical systems, in which the reasoning is rarely much more than a decent pretext for the adoption of foregone conclusions.

To sum up the whole, we should say that the aim of the Platonic philosophy was to exalt man into a god. The aim of the Baconian philosophy was to provide man with what he requires while he continues to be man. The aim of the Platonic philosophy was to raise us far above vulgar wants. The aim of the Baconian philosophy was to supply our vulgar wants. The former aim was noble; but the latter was attainable.

All religions are cruel, all founded on blood; for all rest principally on the idea of sacrifice - that is, on the perpetual immolation of humanity to the insatiable vengeance of divinity.

Boredom is a larval anxiety; depression, a dreamy hatred.

I may say Christianity itself divided into its thousands also, who are disputing, anathematizing and where the laws permit burning and torturing one another for abstractions which no one of them understand, and which are indeed beyond the comprehension of the human mind.

Though love repine, and reason chafe, There came a voice without reply, - "'T is man's perdition to be safe When for the truth he ought to die."

Not only must people know, they must see with their own eyes. Because they must be made to be afraid; but also because they must be the witnesses, the guarantors, of the punishment, and because they must to a certain extent take part in it.

Time, and reflection, and discussion, have produced their natural effect on minds eminently intelligent and candid. No intermediate shades of opinion are now left. There is no twilight. The light has been divided from the darkness. Two parties are ranged in battle array against each other. There is the standard of monopoly. Here is the standard of free trade; and by the standard of free trade I pledge myself to stand firmly.

A dream! What is a dream? And is not our life a dream? I will say more. Suppose that this paradise will never come to pass (that I understand), yet I shall go on preaching it. And yet how simple it is: in one day, in one hour everything could be arranged at once! The chief thing is to love others like yourself, that's the chief thing, and that's everything; nothing else is wanted - you will find out at once how to arrange it all. And yet it's an old truth which has been told and retold a billion times - but it has not formed part of our lives! The consciousness of life is higher than life, the knowledge of the laws of happiness is higher than happiness - that is what one must contend against. And I shall. If only everyone wants it, it can be arranged at once.

Man's unhappiness, as I construe, comes of his greatness; it is because there is an Infinite in him, which with all his cunning he cannot quite bury under the Finite.

I have no patience with those who say that sexual excitement is shameful and that venereal stimuli have their origin not in nature, but in sin. Nothing is so far from the truth. As if marriage, whose function cannot be fulfilled without these incitements, did not rise above blame. In other living creatures, where do these incitements come from? From nature or from sin? From nature, of course. It must borne in mind that in the apetites of the body there is very little difference between man and other living creatures. Finally, we defile by our imagination what of its own nature is fair and holy. If we were willing to evaluate things not according to the opinion of the crowd, but according to nature itself, how is it less repulsive to eat, chew, digest, evacuate, and sleep after the fashion of dumb animals, than to enjoy lawful and permitted carnal relations?
