On the whole, a man who denies the existence of the effects arranged according to the causes in the question of arts, or whose wisdom cannot understand it, then he has no knowledge of the art of its Maker.

It is almost never when a state of things is the most detestable that it is smashed, but when, beginning to improve, it permits men to breathe, to reflect, to communicate their thoughts with each other, and to gauge by what they already have the extent of their rights and their grievances. The weight, although less heavy, seems then all the more unbearable.

There are some simple maxims [...] which I think might be commanded to writers of expository prose. First: never use a long word if a short word will do. Second: if you want to make a statement with a great many qualifications, put some of the qualifications in separate sentences. Third: do not let the beginning of your sentence lead the reader to an expectation which is contradicted by the end.

No regulation of commerce can increase the quantity of industry in any society beyond what its capital can maintain. It can only divert a part of it into a direction into which it might not otherwise have gone; and it is by no means certain that this artificial direction is likely to be more advantageous to the society than that into which it would have gone of its own accord. Every individual is continually exerting himself to find out the most advantageous employment for whatever capital he can command. It is his own advantage, indeed, and not that of the society, which he has in his view. But the study of his own advantage naturally, or rather necessarily leads him to prefer that employment which is most advantageous to the society.

Now, what is 'unrighteousness' in practice? It is in practice behavior of a kind disliked by the herd. By calling it unrighteousness, and by arranging an elaborate system of ethics around this conception, the herd justifies itself in wreaking punishment upon the objects of its own dislike, while at the same time, since the herd is righteous by definition, it enhances its own self-esteem at the very moment when it lets loose its impulse to cruelty. This is the psychology of lynching, and of the other ways in which criminals are punished. The essence of the conception of righteousness, therefore, is to afford an outlet for sadism by cloaking cruelty as justice.

William James used to preach the "will-to-believe." For my part, I should wish to preach the "will-to-doubt." None of our beliefs are quite true; all at least have a penumbra of vagueness and error. What is wanted is not the will to believe, but the will to find out, which is the exact opposite.

He is great who is what he is from Nature, and who never reminds us of others.

I trust a good deal to common fame, as we all must. If a man has good corn, or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods.

As a general rule-never substitute the symbol for the thing signified, unless it is impossible to show the thing itself; for the child's attention is so taken up with the symbol that he will forget what it signifies.

So people should abstain from other animals just as they should from the human.

What needs saying is worth saying twice.

No man is exempt from saying silly things; the mischief is to say them deliberately.

Concerning the female sorcerer. Roman law also prescribes this. Why does the law name women more than men here, even though men are also guilty of this? Because women are more susceptible to those superstitions of Satan; take Eve, for example. They are commonly called "wise women." Let them be killed.

The double meaning has been given to suit people's diverse intelligence. The apparent contradictions are meant to stimulate the learned to deeper study.

One good schoolmaster is of more use than a hundred priests.

An optimistic view of the future would indicate that before long, the clear necessity of expanding humanity's horizons would cause ... space settlements to be built. The construction would also serve as a great project that not only would be clearly of great benefit, but might induce human cooperation in something large enough to fire the heart and mind, and make people forget the petty quarrels that have engaged them for thousands of years in wars over insignificant scraps of earthly territory.

Opinion is like a pendulum and obeys the same law. If it goes past the centre of gravity on one side, it must go a like distance on the other; and it is only after a certain time that it finds the true point at which it can remain at rest.

I construct my memories with my present. I am lost, abandoned in the present. I try in vain to rejoin the past: I cannot escape.

In the history of madness, two events signal this change with singular clarity: in 1657, the founding of the Hôpital Général, and the Great Confinement of the poor; and in 1794, the liberation of the mad in chains at Bicêtre. Between these two singular and symmetrical events, something happened, whose ambiguity has perplexed historians of medicine: blind repression in an absolutist regime, according to some, and, according to others, the progressive discovery, by science and philanthropy, of madness in its positive truth. In fact, beneath these reversible meanings, a structure was taking shape, which did not undo that ambiguity but was decisive for it. This structure explains the passage from the medieval and humanist experience of madness to the experience that is our own, which confines madness in mental illness.

I did not know the way in which, among the ordinary English, the absence of interest in things of an unselfish kind, except occasionally in a special thing here and there, and the habit of not speaking to others, nor much even to themselves, about the things in which they do feel interest, causes both their feelings and their intellectual faculties to remain undeveloped, or to develope themselves only in some single and very limited direction; reducing them, considered as spiritual beings, to a kind of negative existence.

A public can only arrive at enlightenment slowly. Through revolution, the abandonment of personal despotism may be engendered and the end of profit-seeking and domineering oppression may occur, but never a true reform of the state of mind. Instead, new prejudices, just like the old ones, will serve as the guiding reins of the great, unthinking mass. All that is required for this enlightenment is freedom; and particularly the least harmful of all that may be called freedom, namely, the freedom for man to make public use of his reason in all matters. But I hear people clamor on all sides: Don't argue! The officer says: Don't argue, drill! The tax collector: Don't argue, pay! The pastor: Don't argue, believe!

Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. 

And these were the dishes wherein to me, hunger-starven for thee, they served up the sun and the moon.

Plato had defined Man as an animal, biped and featherless, and was applauded. Diogenes plucked a fowl and brought it into the lecture-room with the words, "Behold Plato's man!"

Percepts and phenomena which precedes the logical use of the intellect is called appearance, while the reflex knowledge originating from several appearances compared by the intellect is called experience.

If this life be not a real fight, in which something is eternally gained for the universe by success, it is no better than a game of private theatricals from which one may withdraw at will. But it feels like a real fight.

Nicias, do you think you can erase with good deeds the wrongs you committed against your mother? What good deed will ever reach her? Her soul is a scorching noon time, without a single breath of a breeze, nothing moves, nothing changes, nothing lives there; a great emaciated sun, an immobile sun eternally consumes her.

The bodies of which the world is composed are solids, and therefore have three dimensions. Now, three is the most perfect number, it is the first of numbers, for of one we do not speak as a number, of two we say both, but three is the first number of which we say all. Moreover, it has a beginning, a middle, and an end.

God's justice and His power are inseparable; 'tis in vain we invoke His power in an unjust cause. We are to have our souls pure and clean, at that moment at least wherein we pray to Him, and purified from all vicious passions; otherwise we ourselves present Him the rods wherewith to chastise us; instead of repairing anything we have done amiss, we double the wickedness and the offence when we offer to Him, to whom we are to sue for pardon, an affection full of irreverence and hatred. Which makes me not very apt to applaud those whom I observe to be so frequent on their knees, if the actions nearest to the prayer do not give me some evidence of amendment and reformation

She is the sum of nature's universe.To her perfection all of beauty tends.

I hate the world and almost all the people in it. I hate the Labour Congress and the journalists who send men to be slaughtered, and the fathers who feel a smug pride when their sons are killed, and even the pacifists who keep saying human nature is essentially good, in spite of all the daily proofs to the contrary. I hate the planet and the human race - I am ashamed to belong to such a species.

The capitalist cannot store labour-power in warehouses after he has bought it, as he may do with the raw material.

Philosophy's position with regard to science, which at one time could be designated with the name "theory of knowledge," has been undermined by the movement of philosophical thought itself. Philosophy was dislodged from this position by philosophy.

A country cannot subsist well without liberty, nor liberty without virtue.

I don't think that there are any sinister persons deliberately trying to rob people of their freedom but I do think, first of all, that there are a number of impersonal forces which are pushing in the direction of less and less freedom. And I also thing there are a number of technological devices which anybody who wishes to use, can use, to accelerate this process of going away from freedom, of imposing control.

Animals only follow their natural instincts; but man, unless he has experienced the influence of learning and philosophy, is at the mercy of impulses that are worse than those of a wild beast. There is no beast more savage and dangerous than a human being who is swept along by the passions of ambition, greed, anger, envy, extravagance, and sensuality.

The lowest degree of education is to distinguish oneself from the ignorant ordinary man. The educated man does not loathe honey even if he finds it in the surgeon's cupping-glass; he realizes that the cupping glass does not essentially alter the honey. The natural aversion from it in such a case rests on popular ignorance, arising from the fact that the cupping-glass is made only for impure blood. Men imagine that the blood is impure because it is in the cupping-glass, and are not aware that the impurity is due to a property.

When I play with my cat, who knows if I am not a pastime to her more than she is to me?

Again and again our foe, religion, has given birth to deeds sinful and unholy.

The Vedas contain a sensible account of God." "The veneration in which the Vedas are held is itself a remarkable feat. Their code embraced the whole moral life of the Hindus and in such a case there is no other truth than sincerity. Truth is such by reference to the heart of man within, not to any standard without.

The souls of emperors and cobblers are cast in the same mold...The same reason that makes us wrangle with a neighbor creates a war betwixt princes.

To worship to other than one's own ancestral spirits is brown-nosing. If you see what is right and fail to act on it, you lack courage. Variant: To see what is right, and not to do it, is want of courage or of principle.

Be not swept off your feet by the vividness of the impression, but say, "Impression, wait for me a little. Let me see what you are and what you represent. Let me try you."

The world thought well of my schoolmaster guardian, because he was neither a liar, nor a scamp, nor a gambler; but he was coarse, avaricious, and ignorant; he knew nothing beyond the confused lessons which he taught to his classes. He imagined that in forcing a youth to become a monk he would be offering a sacrifice acceptable to God. He used to boast of the many victims which he devoted annually to Dominic and Francis and Benedict.

When we have chosen the vocation in which we can contribute most to humanity, burdens cannot bend us because they are only sacrifices for all. Then we experience no meager, limited, egotistic joy, but our happiness belongs to millions, our deeds live on quietly but eternally effective, and glowing tears of noble men will fall on our ashes.

Men use thought only to justify their wrongdoings, and speech only to conceal their thoughts.

Nobody should ever doubt that in the washing of rebirth (Titus 3:5) absolutely all sins, from the least to the greatest, are altogether forgiven.

Man know thyself; then thou shalt know the Universe and God.
