The order of nature cannot be justified by the mere observation of nature. For there is nothing in the present fact which inherently refers either to the past or to the future.... It illustrates the anti-rationalism of the scientific public that, when Hume did appear, it was only the religious implications of his philosophy which attracted attention. This was because the clergy were in principle rationalists, whereas the men of science were content with a simple faith in the order of nature.

It is only afterward that a new idea seems reasonable. To begin with, it usually seems unreasonable.

Our whole past experience is continually in our consciousness, though most of it sunk to a great depth of dimness. I think of consciousness as a bottomless lake, whose waters seem transparent, yet into which we can clearly see but a little way.

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

The world is nothing but change. Our life is only perception.

Where any answer is possible, all answers are meaningless.

If this superstitious fear of Spirits were taken away, and with it, Prognostiques from Dreams, false Prophecies, and many other things depending thereon, by which, crafty ambitious persons abuse the simple people, men would be much more fitted then they are for civill Obedience.

What is Europe really but a sterile trunk which owes everything to oriental grafts?

Where there is politics or economics, there is no morality.

There is no means of proving it is preferable to be than not to be.

I believe that if an individual is not on the path to transcending his society and seeing in what way it furthers or impedes the development of human potential, he cannot enter into intimate contact with his humanity. If the tabus, restrictions, distorted values appear "natural" to him, this is a clear indication that he cannot have a real knowledge of human nature. I believe that society, while having a function both stimulating and inhibiting at the same time, has always been in conflict with humanity. Only when the purpose of society is identified with that of humanity will society cease to paralyze man and encourage his dominance.

Let words proceed as they please, provided only your soul keeps its own sure order, provided your soul is great and holds unruffled to its ideals, pleased with itself on account of the very things which displease others, a soul that makes life the test of its progress, and believes that its knowledge is in exact proportion to its freedom from desire and its freedom from fear.

Inquiry into the evidence of a doctrine is not to be made once for all, and then taken as finally settled. It is never lawful to stifle a doubt; for either it can be honestly answered by means of the inquiry already made, or else it proves that the inquiry was not complete. "But," says one, "I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments." Then he should have no time to believe.

He was as great as a man can be without morality.

No man can have society upon his own terms. If he seeks it, he must serve it too.

Nothing can discourage the appetite for divinity in the heart of man.

I don't think there would be many jokes, if there weren't constant frustration and fear and so forth. It's a response to bad troubles like crime.

The advance of science is not comparable to the changes of a city, where old edifices are pitilessly torn down to give place to new, but to the continuous evolution of zoologic types which develop ceaselessly and end by becoming unrecognizable to the common sight, but where an expert eye finds always traces of the prior work of the centuries past. One must not think then that the old-fashioned theories have been sterile or vain.

There are 80,000 prostitutes in London alone and what are they, if not bloody sacrifices on the altar of monogamy?

In one sense, I do believe I am "like a man," as Parthe [the writer's sister] says. But how? In having sympathy. ... Women crave for being loved, not for loving. They scream out at you for sympathy all day long, they are incapable of giving any in return, for they cannot remember your affairs long enough to do so. ... They cannot state a fact accurately to another, nor can that other attend to it accurately enough for it to become information. Now is not all this the result of want of sympathy?

Supreme power rests in the will of all or of the majority.

Of all people, girls and servants are the most difficult to behave to. If you are familiar with them, they lose their humility. If you maintain a reserve towards them, they are discontented.

See now the power of truth; the same experiment which at first glance seemed to show one thing, when more carefully examined, assures us of the contrary.

Battles, in these ages, are transacted by mechanism; with the slightest possible development of human individuality or spontaneity: men now even die, and kill one another, in an artificial manner.

The old often envy the young; when they do, they are apt to treat them cruelly.

The global village is a place of very arduous interfaces and very abrasive situations.

Philosophy is like trying to open a safe with a combination lock: each little adjustment of the dials seems to achieve nothing, only when everything is in place does the door open.

I think these things firearms were invented by Satan himself, for they can't be defended against with (ordinary) weapons and fists. All human strength vanishes when confronted with firearms. A man is dead before he sees what's coming.

By faithfulness we are collected and wound up into unity within ourselves, whereas we had been scattered abroad in multiplicity.

Never read any book that is not a year old.

We have become blind to the alternatives to violence. This involves us in a sort of official madness, in which, while following what seems to be a perfect logic of self-defense and deterrence, we commit one absurdity after another: We seek to preserve peace by fighting a war, or to advance freedom by subsidizing dictatorships, or to "win the hearts and minds of the people" by poisoning their crops and burning their villages and confining them in concentration camps; we seek to uphold the "truth" of our cause with lies, or to answer conscientious dissent with threats and slurs and intimidations. ... I have come to the realization that I can no longer imagine a war that I would believe to be either useful or necessary. I would be against any war.

In contemplating thyself never include the vessel which surrounds thee, and these instruments which are attached about it. For they are like an ax, differing only in this, that they grow to the body. For indeed there is no more use in these parts without the cause which moves and checks them than in the weaver's shuttle, and the writer's pen, and the driver's whip.

For what are they all in their high conceit, When man in the bush with God may meet?

Diversity makes critical argument fruitful. ...[P]artners in an argument must share ...the wish to know, and the readiness to learn from the other ...by severely criticizing his views... and hearing... [the] reply. ...the so-called method of science consists in this kind of criticism.

There is no virtue they should be excited to, nor fault they should be kept from, which I do not think they may be convinced of; but it must be by such reasons as their age and understandings are capable of, and those propos'd always in very few and plain words.

Alexander, king of Macedon, began to study geometry; unhappy man, because he would thereby learn how puny was that earth of which he had seized but a fraction! Unhappy man, I repeat, because he was bound to understand that he was bearing a false title. For who can be "great" in that which is puny?

If, in my retirement to the humble station of a private citizen, I am accompanied with the esteem and approbation of my fellow citizens, trophies obtained by the blood-stained steel, or the tattered flags of the tented field, will never be envied. The care of human life and happiness, and not their destruction, is the first and only legitimate object of good government.

We have seen that language is something precious because it allows us to express ourselves; but it is fatal when one allows oneself to be completely led astray by it, because then it prevents one from expressing oneself. Language is the source of the prejudices and haste which Descartes thought of as the sources of error.

To recognize a difficulty is not to solve it.

Every man is his own doctor of divinity, in the last resort.

A Dialogue between two Infants in the womb concerning the state of this world, might handsomely illustrate our ignorance of the next, whereof methinks we yet discourse in Plato's Den, and are but Embryon Philosophers.

To dissimulate is to pretend not to have what one has. To simulate is to feign to have what one doesn't have. One implies a presence, the other an absence. But it is more complicated than that because simulating is not pretending: "Whoever fakes an illness can simply stay in bed and make everyone believe he is ill. Whoever simulates an illness produces in himself some of the symptoms" (Littré). Therefore, pretending, or dissimulating, leaves the principle of reality intact: the difference is always clear, it is simply masked, whereas simulation threatens the difference between the "true" and the "false," the "real" and the "imaginary."

Such religion as there can be in modern life, every individual will have to salvage from the churches for himself.

Nonsense. You are a military man and should know better. If there is one science into which man has probed continuously and successfully, it is that of military technology. No potential weapon would remain unrealized for ten thousand years.

The full expression of personality depends upon its being inflated by social prestige; it is a social privilege.

Jacques said that his master said that everything good or evil we encounter here below was written on high.

Use harms and even destroys beauty. The noblest function of an object is to be contemplated.
