An old fairy tale has it that science began with the rejection of superstition. In fact it was the rejection of rationalism that gave birth to scientific inquiry. Ancient and medieval thinkers believed the world could be understood by applying first principles. Modern science begins when observation and experiment come first, and the results are accepted even when what they show seems to be impossible.

We must make a very precise distinction between the official and consequently dictatorial prerogatives of society organized as a state, and of the natural influence and action of the members of a non-official, non-artificial society.

Who else is the enemy of Nature but he who mistakes himself for more intelligent than Nature, though it is the highest school for all of us?

Those animals which are incapable of making binding agreements with one another not to inflict nor suffer harm are without either justice or injustice; and likewise for those peoples who either could not or would not form binding agreements not to inflict nor suffer harm.

I am responsible for everything ... except for my very responsibility, for I am not the foundation of my being. Therefore everything takes place as if I were compelled to be responsible. I am abandoned in the world ... in the sense that I find myself suddenly alone and without help, engaged in a world for which I bear the whole responsibility without being able, whatever I do, to tear myself away from this responsibility for an instant.

As far as I am concerned, I resign from humanity. I no longer want to be, nor can still be, a man. What should I do? Work for a social and political system, make a girl miserable? Hunt for weaknesses in philosophical systems, fight for moral and aesthetic ideals? It's all too little. I renounce my humanity even though I may find myself alone. But am I not already alone in this world from which I no longer expect anything?

Language is a skin: I rub my language against the other. It is as if I had words instead of fingers, or fingers at the tip of my words. My language trembles with desire.

Whatever you would make habitual, practice it; and if you would not make a thing habitual, do not practice it, but accustom yourself to something else.

There is in our souls some native seed of reason, which, if nourished by good counsel and training, flowers into virtue, but which, on the other hand, if unable to resist the vices surrounding it, is stifled and blighted.

I may become a poor man; I shall then be one among many. I may be exiled; I shall then regard myself as born in the place to which I shall be sent. They may put me in chains. What then? Am I free from bonds now? Behold this clogging burden of a body, to which nature has fettered me! "I shall die," you say; you mean to say "I shall cease to run the risk of sickness; I shall cease to run the risk of imprisonment; I shall cease to run the risk of death."

So long as man remains free he strives for nothing so incessantly and so painfully as to find someone to worship. But man seeks to worship what is established beyond dispute, so that all men would agree at once to worship it. For these pitiful creatures are concerned not only to find what one or the other can worship, but to find community of worship is the chief misery of every man individually and of all humanity from the beginning of time. For the sake of common worship they've slain each other with the sword. They have set up gods and challenged one another, 'Put away your gods and come and worship ours, or we will kill you and your gods!' And so it will be to the end of the world, even when gods disappear from the earth; they will fall down before idols just the same.

The sublime is excited in me by the great stoical doctrine, Obey thyself.

Much reading has brought upon us a learned barbarism.

For it is extremely absurd to expect to be enlightened by reason, and yet to prescribe to her beforehand on which side she must incline.

Proverbs about truth are well-loved in Russian. They give steady and sometimes striking expression to the not inconsiderable harsh national experience: ONE WORD OF TRUTH SHALL OUTWEIGH THE WHOLE WORLD. And it is here, on an imaginary fantasy, a breach of the principle of the conservation of mass and energy, that I base both my own activity and my appeal to the writers of the whole world.

The difference between the first- and second-best things in art absolutely seems to escape verbal definition - it is a matter of a hair, a shade, an inward quiver of some kind - yet what miles away in the point of preciousness!

For my part, I travel not to go anywhere, but to go. I travel for travel's sake. The great affair is to move.

Bad company will lead a man to the gallows!

For the inquisition of Final Causes is barren, and like a virgin consecrated to God produces nothing.

Botany is the school for patience, and it's amateurs learn resignation from daily disappointments.

When it is evening, ye say, It will be fair weather: for the sky is red. And in the morning, It will be foul weather to day: for the sky is red and lowring. O ye hypocrites, ye can discern the face of the sky; but can ye not discern the signs of the times? A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas.

I would take to be quite a fool any man who would make a book full of laws and statutes for an apple tree telling it how to bear apples and not thorns, when the tree is able by its own nature to do this better than the man with all his books can describe and demand.

In many cases it is a matter for decision and not a simple matter of fact whether x understands y; and so on.

First, most producers are employees of firms, not owners. Viewed from the vantage point of classical economic theory, they have no reason to maximize the profits of firms, except to the extent that they can be controlled by owners. Moreover, profit-making firms, nonprofit organizations, and bureaucratic organizations all have exactly the same problem of inducing their employees to work toward organizational goals. There is no reason, a priori, why it should be easier (or harder) to produce this motivation in organizations aimed at maximizing profits than in organizations with different goals. If it is true in an organizational economy that organizations motivated by profits will be more efficient than other organizations, additional postulates will have to be introduced to account for it.

The universal intelligence puts itself in motion for every separate effect... or it puts itself in motion once, and everything else comes by way of a sequence in a manner; or individual elements are the origin of all things. In a word, if there is a god, all is well; and if chance rules, do not thou be governed by it.

The social contract between all people around the world only has one requirement: Don't kill. From there it's those who don't agree, those that agree but have some reactive justification, and those that agree and don't kill.

A vehement eros runs through the Universe. It is like the ether: harder than steel, softer than air. It cuts through and passes beyond all things, it flees and escapes.

Respect the child. Be not too much his parent. Trespass not on his solitude.

Europe has made much; great cities, great empires, encyclopaedias, creeds, bodies of opinion and practice: but it has made little of the class of Dante's Thought.

Experience teaches only the teachable...

So long as one can use scented candy to abate the foul breath of hypocrisy, Puritanism is triumphant.

No one can be a great thinker who does not recognise, that as a thinker it is his first duty to follow his intellect to whatever conclusions it may lead...Not that it is solely, or chiefly, to form great thinkers, that freedom of thinking is required. On the contrary, it is as much and even more indispensable to enable average human beings to attain the mental stature which they are capable of.

Now to get back to our given Church: it lives almost entirely for modesty and moneyed piety. It zealously inveighs against the harm done to Joseph and the sheep, but it has made its arrangements with the upper classes and serves as their spiritual defender. It bristles at see-through blouses, but not at slums in which half-naked children starve, and not, above all, at the conditions that keep three quarters of mankind in misery. It condemns desperate girls who abort a foetus, but it consecrates war, which aborts millions. It has nationalized its God, nationalized him into ecclesiastic organization, and has inherited the Roman empire under the mask of the Crucified. It preserves misery and injustice, having first tolerated and then approved the class power that causes them; it prevents any seriousness about deliverance by postponing it to St. Never-Ever's Day or shifting it to the beyond.

However long Jewish, Christian and Muslim theologians struggle to find multiple meanings in this text, the dominant seems to be this: Abraham's unquestioning willingness to heed gods command to sacrifice the thing he loved most is what qualified him to become the father of what are called still the Abrahamic faiths.

O light! This is the cry of all the characters of ancient drama brought face to face with their fate. This last resort was ours, too, and I knew it now. In the middle of winter I at last discovered that there was in me an invincible summer. Return to Tipasa (1954) Variant translation: In the depths of winter, I finally learned that within me there lay an invincible summer.

I ... understand why the saints were rarely married women. I am convinced it has nothing inherently to do, as I once supposed, with chastity or children. It has primarily to do with distractions ... Women's normal occupations in general run counter to creative life, or contemplative life or saintly life.

Be ye therefore ready also: for the Son of man cometh at an hour when ye think not.

I do not believe in what is often called... 'exact terminology'... [or] in definitions... [they] do not... add to exactness... I especially dislike pretentious terminology and... pseudo-exactness concerned with it.

The students of physical science are not unfrequently told that their pursuits unfit them for the estimation of moral probability. And it may be so, for I am afraid that to those who are accustomed to severe reasoning, either in the province of Science or in that of Law, reasoning from 'moral probability' is apt to be regarded as a process of accumulating inconclusive arguments, in the hope that a great heap of them may, at least, look as firm as one good demonstration.

Rational and kindly behavior tends to produce good results and these results remain good even when the behavior which produced them was itself produced by a pill.

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

When we have intelligence resulting from sincerity, this condition is to be ascribed to nature; when we have sincerity resulting from intelligence, this condition is to be ascribed to instruction. But given the sincerity, and there shall be the intelligence; given the intelligence, and there shall be the sincerity.

Our preaching does not stop with the law. That would lead to wounding without binding up, striking down and not healing, killing and not making alive, driving down to hell and not bringing back up, humbling and not exalting. Therefore, we must also preach grace and the promise of forgiveness - this is the means by which faith is awakened and properly taught. Without this word of grace, the law, contrition, penitence, and everything else are done and taught in vain.

Distance is a great promoter of admiration!

Moreover, there is a victory and defeat, the first and best of victories, the lowest and worst of defeat, which each man gains or sustains at the hands, not of another, but of himself; this shows that there is a war against ourselves going on within every one of us. Book I Sometimes paraphrased as "The first and best victory is to conquer self".

The Idols of Tribe have their foundation in human nature itself, and in the tribe or race of men. For it is a false assertion that the sense of man is the measure of things. On the contrary, all perceptions as well of the sense as of the mind are according to the measure of the individual and not according to the measure of the universe. And the human understanding is like a false mirror, which, receiving rays irregularly, distorts and discolors the nature of things by mingling its own nature with it.

One loves to possess arms, though they hope never to have occasion for them.
