Again, we should notice the force, effect, and consequences of inventions, which are nowhere more conspicuous than in those three which were unknown to the ancients; namely, printing, gunpowder, and the compass. For these three have changed the appearance and state of the whole world; first in literature, then in warfare, and lastly in navigation: and innumerable changes have been thence derived, so that no empire, sect, or star, appears to have exercised a greater power and influence on human affairs than these mechanical discoveries.

The best and greatest winning is a true friend; and the greatest loss is the loss of time.

I cleave the heavens and soar to the infinite. And while I rise from my own globe to others And penetrate ever further through the eternal field, That which others saw from afar, I leave far behind me. Variant translation: While I venture out beyond this tiny globe Into reaches past the bounds of starry night I leave behind what others strain to see afar.

Keep cool: it will be all one a hundred years hence.

If it were true what in the end would be gained? Nothing but another truth. Is this such a mighty advantage? We have enough old truths still to digest, and even these we would be quite unable to endure if we did not sometimes flavor them with lies.

Hear gladly!

Formerly, it was held by philosophers and mathematicians alike that the proofs in Geometry depended on the figure; nowadays, this is known to be false. In the best books there are no figures at all. The reasoning proceeds by the strict rules of formal logic from a set of axioms laid down to begin with.

In historical events great men - so-called - are but labels serving to give a name to the event, and like labels they have the least possible connection with the event itself. Every action of theirs, that seems to them an act of their own free will, is in an historical sense not free at all, but in bondage to the whole course of previous history, and predestined from all eternity.

The study of Ethics would, no doubt, be far more simple, and its results far more "systematic," if, for instance, pain were an evil of exactly the same magnitude as pleasure is a good; but we have no reason whatever to assume that the Universe is such that ethical truths must display this kind of symmetry ... .

The Puritan hated bear-baiting, not because it gave pain to the bear, but because it gave pleasure to the spectators.

This tendency towards a Christian-European Universal Monarchy has shown itself successively in the several States which could make pretensions to such a dominion, and, since the fall of the Papacy, it has become the sole animating principle of our History. We by no means seek to determine whether this notion of Universal Monarchy has ever been distinctly entertained as a definite plan .... Thus each State either strives to attain this Universal Christian Monarchy, or at least to acquire the power of striving after it;-to maintain the Balance of Power when it is in danger of being disturbed by another; and, in secret, for power, that it may eventually disturb it itself.

Is the position tenable, that certain phenomena, possible in Euclidean space, would be impossible in non-Euclidean space, so that experience, in establishing these phenomena, would directly contradict the non-Euclidean hypothesis? For my part I think no such question can be put. To my mind it is precisely equivalent to the following, whose absurdity is patent to all eyes: are there lengths expressible in meters and centimeters, but which can not be measured in fathoms, feet, and inches, so that experience, in ascertaining the existence of these lengths, would directly contradict the hypothesis that there are fathoms divided into six feet?

One thing I have frequently observed in children, that when they have got possession of any poor creature, they are apt to use it ill: they often torment, and treat it very roughly, young birds, butterflies, and such other poor animals which fall into their hands, and that with a seeming kind of pleasure. This I think should be watched in them, and if they incline to any such cruelty, they should be taught the contrary usage. For the custom of tormenting and killing of beasts, will, by degrees, harden their minds even towards men; and they will delight in the suffering and destruction of inferior creatures, will not be apt to be very compassionate or benign to those of their own kind. Our practice takes notice of this in the exclusion of butchers from juries of life and death.

All traditional logic habitually assumes that precise symbols are being employed. It is therefore not applicable to this terrestial life but only to an imagined celestial existence... logic takes us nearer to heaven than other studies.

Quiet minds cannot be perplexed or frightened but go on in fortune or misfortune at their own private pace, like a clock during a thunderstorm.

When the husk gets separated from the kernel, almost all men run after the husk and pay their respects to that. It is only the husk of Christianity that is so bruited and wide spread in this world; the kernel is still the very least and rarest of all things. There is not a single church founded on it.

The seat of faith, however, is not consciousness but spontaneous religious experience, which brings the individual's faith into immediate relation with God. Here we must ask: Have I any religious experience and immediate relation to God, and hence that certainty which will keep me, as an individual, from dissolving in the crowd?

Giving alms is only a virtuous deed when you give money that you yourself worked to get.

It is very well to say "be prudent, be careful, try to know each other." But how are you to know each other? Unless a woman had lost all pride, how is it possible for her, under the eyes of all her family, to indulge in long exclusive conversations with a man? "Such a thing" must not take place till after her "engagement." And how is she to make an engagement, if "such a thing" has not taken place?

Owing to the identification of religion with virtue, together with the fact that the most religious men are not the most intelligent, a religious education gives courage to the stupid to resist the authority of educated men, as has happened, for example, where the teaching of evolution has been made illegal. So far as I can remember, there is not one word in the Gospels in praise of intelligence; and in this respect ministers of religion follow gospel authority more closely than in some others.

The obsession with suicide is characteristic of the man who can neither live nor die, and whose attention never swerves from this double impossibility.

So watch yourselves. If your brother sins, rebuke him, and if he repents, forgive him. If he sins against you seven times in a day, and seven times comes back to you and says, 'I repent,' forgive him.

The supreme accomplishment is to blur the line between work and play.

Self-pity is not as sterile as we suppose. Once we feel its mere onset, we assume a thinker's attitude, and come to think of it, we come to think!

Only the great generalizations survive. The sharp words of the Declaration of Independence, lampooned then and since as 'glittering generalities,' have turned out blazing ubiquities that will burn forever and ever.

Bourgeois norms are experienced as the evident laws of a natural order-the further the bourgeois class propagates its representations, the more naturalized they become.

The value of a principle is the number of things it will explain; and there is no good theory of disease which does not at once suggest a cure.

On fact, the whole machinery of our intelligence, our general ideas and laws, fixed and external objects, principles, persons, and gods, are so many symbolic, algebraic expressions. They stand for experience; experience which we are incapable of retaining and surveying in its multitudinous immediacy. We should flounder hopelessly, like the animals, did we not keep ourselves afloat and direct our course by these intellectual devices.

Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and, however early a man's training begins, it is probably the last lesson that he learns thoroughly.

At the core of all well-founded belief, lies belief that is unfounded.

When Eudæmonidas heard a philosopher arguing that only a wise man can be a good general, "This is a wonderful speech," said he; "but he that saith it never heard the sound of trumpets."

There are no arguments. Can anyone who has reached the limit bother with arguments, causes, effects, moral considerations, and so forth? Of course not. For such a person there are only unmotivated motives for living. On the heights of despair, the passion for the absurd is the only thing that can still throw a demonic light on chaos. When all the current reasons - moral, esthetic, religious, social, and so on - no longer guide one's life, how can one sustain life without succumbing to nothingness? Only by a connection with the absurd, by love of absolute uselessness, loving something which does not have substance but which simulates an illusion of life. I live because the mountains do not laugh and the worms do not sing.

O slavish man! will you not bear with your own brother, who has God for his Father, as being a son from the same stock, and of the same high descent? But if you chance to be placed in some superior station, will you presently set yourself up for a tyrant?

There is needed, no doubt, a body of servants (ministerium) of the invisible church, but not officials (officiales), in other words, teachers but not dignitaries, because in the rational religion of every individual there does not yet exist a church as a universal union (omnitudo collectiva).

Boundless compassion for all living beings is the surest and most certain guarantee of pure moral conduct, and needs no casuistry. Whoever is filled with it will assuredly injure no one, do harm to no one, encroach on no man's rights; he will rather have regard for every one, forgive every one, help every one as far as he can, and all his actions will bear the stamp of justice and loving-kindness. ... In former times the English plays used to finish with a petition for the King. The old Indian dramas close with these words: "May all living beings be delivered from pain." Tastes differ; but in my opinion there is no more beautiful prayer than this.

We often attribute "understanding" and other cognitive predicates by metaphor and analogy to cars, adding machines, and other artifacts, but nothing is proved by such attributions.

Aristotle's view that philosophy begins with wonder, not as in our day with doubt, is a positive point of departure for philosophy. Indeed, the world will no doubt learn that it does not do to begin with the negative, and the reason for success up to the present is that philosophers have never quite surrendered to the negative and thus have never earnestly done what they have said. They merely flirt with doubt.

All of the other people have committed crimes, the Jews are the only ones who have boasted about committing them. They are, all of them, born with raging fanaticism in their hearts, just as the Bretons and the Germans are born with blond hair. I would not be in the least bit surprised if these people would not some day become deadly to the human race.

Hegel's philosophy was an integral part of the culture which authoritarianism had to overcome. It is therefore no accident that the National Socialist assault on Hegel begins with the repudiation of his political theory.

We do not know whether Hitler is going to found a new Islam. (He is already on the way; he is like Mohammed. The emotion in Germany is Islamic; warlike and Islamic. They are all drunk with a wild god.)

"Let us work without reasoning," said Martin; "it is the only way to make life endurable."

The American who first discovered Columbus made a bad discovery.

Even in childhood I watched the hours flow, independent of any reference, any action, any event, the disjunction of time from what was not itself, its autonomous existence, its special status, its empire, its tyranny. I remember quite clearly that afternoon when, for the first time, confronting the empty universe, I was no more than a passage of moments reluctant to go on playing their proper parts. Time was coming unstuck from being - at my expense.

Every utopia about to be realized resembles a cynical dream.

The first consequence of the principle of bounded rationality is that the intended rationality of an actor requires him to construct a simplified model of the real situation in order to deal with it. He behaves rationally with respect to this model, and such behavior is not even approximately optimal with respect to the real world. To predict his behavior we must understand the way in which this simplified model is constructed, and its construction will certainly be related to his psychological properties as a perceiving, thinking, and learning animal.

Dogmatics must be designed in this way. Above all, every science must vigorously lay hold of its own beginning and not live in complicated relations with other sciences. If dogmatics begins by wanting to explain sinfulness or by wanting to prove its actuality, no dogmatics will come out of it, but the entire existence of dogmatics will become problematic and vague.

Although the whole of this life were said to be nothing but a dream and the physical world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.
