Commit no slander; so that infamy and wickedness may not happen unto thee.

As surgeons keep their instruments and knives always at hand for cases requiring immediate treatment, so shouldst thou have thy thoughts ready to understand things divine and human, remembering in thy every act, even the smallest, how close is the bond that unites the two.

The will of man has no power whatever over his opinions; he must, and ever did, and ever will, believe what has been, is, or may be impressed on his mind by his predecessors, and the circumstances which surround him.

There is not a negro from the coast of Africa who does not, in this respect, possess a degree of magnanimity which the soul of his sordid master is too often scarce capable of conceiving. Fortune never exerted more cruelly her empire over mankind, than when she subjected those nations of heroes to the refuse of the jails of Europe, to wretches who possess the virtues neither of the countries which they come from, nor of those which they go to, and whose levity, brutality, and baseness, so justly expose them to the contempt of the vanquished.

...out of the tomb of the murdered Monarchy in France, has arisen a vast, tremendous, unformed spectre, in a far more terrific guise than any which ever yet have overpowered the imagination and subdued the fortitude of man.

The person who screams, or uses the superlative degree, or converses with heat, puts whole drawing-rooms to flight. If you wish to be loved, love measure. You must have genius or a prodigious usefulness if you will hide the want of measure.

Since I have spread my wings to purpose high, The more beneath my feet the clouds I see, The more I give the winds my pinions free, Spurning the earth and soaring to the sky.

Virtue is reason which has become energy.

There was a brief moment after 9/11 when Colin Powell said "we should not rush to satisfy the desire for revenge." It was a great moment, an extraordinary moment, because what he was actually asking people to do was to stay with a sense of grief, mournfulness, and vulnerability.

Do not hire a man who does your work for money, but him who does it for love of it.

You should hammer your iron when it is glowing hot.

The art of progress is to preserve order amid change, and to preserve change amid order.

The straightening board was created because of warped wood, and the plumb line came into being because of things that are not straight. Rulers are established and ritual and rightness are illuminated because the nature is evil.

My life was not useless; I gave important truths to the world, and it was only for want of understanding that they were disregarded. I have been ahead of my time.

There were never in the world two opinions alike, any more than two hairs or two grains. Their most universal quality is diversity.

Love responsibility. Say: "It is my duty, and mine alone, to save the earth. If it is not saved, then I alone am to blame." Love each man according to his contribution in the struggle. Do not seek friends; seek comrades-in-arms.

I will not accept boundaries; appearances cannot contain me; I choke! To bleed in this agony, and to live it profoundly, is the second duty. The mind is patient and adjusts itself, it likes to play; but the heart grows savage and will not condescend to play; it stifles and rushes to tear apart the nets of necessity.

If it is not right, do not do it, if it is not true, do not say it. For let thy efforts be -

Worse than war is the very fear of war.

And when his hours are numbered, and the world Is all his own, retiring, as he were not, Leaves, when the sun appears, astonished Art To mimic in slow structures, stone by stone Built in an age, the mad wind's night-work, The frolic architecture of the snow.

No mathematician can give any meaning to language about matter, force, inertia, used in text-books of mechanics.

Sadism is plainly connected with the need for self-assertion. At the same time it cannot be separated from the idea of defeat. A sadist is a man, who, in some sense, has his back to the wall. Nothing is further from sadism, for example, than the cheerful, optimistic mentality of a Shaw or Wells.

I don't understand how people can believe in God, even when I myself think of him everyday.

Electricity does not centralize, but decentralizes.

It is remarkable that, notwithstanding the universal favor with which the New Testament is outwardly received, and even the bigotry with which it is defended, there is no hospitality shown to, there is no appreciation of, the order of truth with which it deals.

If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence?

"I am like a broken puppet whose eyes have fallen inside." This remark of a mental patient weighs more heavily than a whole stack of works on introspection.

Lycurgus the Lacedæmonian brought long hair into fashion among his countrymen, saying that it rendered those that were handsome more beautiful, and those that were deformed more terrible. To one that advised him to set up a democracy in Sparta, "Pray," said Lycurgus, "do you first set up a democracy in your own house."

In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind. If any false opinion, embraced from appearances, has been found to prevail; as soon as farther experience and sounder reasoning have given us juster notions of human affairs, we retract our first sentiment, and adjust anew the boundaries of moral good and evil.

Besides agreeing with the aims of vegetarianism for aesthetic and moral reasons, it is my view that a vegetarian manner of living by its purely physical effect on the human temperament would most beneficially influence a lot of mankind.

Every living creature is happy when he fulfills his destiny, that is, when he realizes himself, when he is being that which in truth he is. For this reason, Schlegel, inverting the relationship between pleasure and destiny, said, "We have a genius for what we like." Genius, man's superlative gift for doing something, always carries a look of supreme pleasure.

The Being of the universe, at first hidden and concealed, has no power which can offer resistance to the search for knowledge ; it has to lay itself open before the seeker - to set before his eyes and give for his enjoyment, its riches and its depths.

Our psychological experiences are all equally facts. There is nothing to choose between them. No psychological experience is "truer," so far as we are concerned, than any other. For even if one should correspond more closely to things in themselves as perceived by some hypothetical non-human being, it would be impossible for us to discover which it was. Science is no "truer" than common sense, or lunacy, or art, or religion. It permits us to organize our experience profitably; but tells us nothing about the real nature of the world to which our experiences are supposed to refer. From the internal reality, by which I mean the totality of psychological experiences, it actually separates us. Art, for example, deals with many more aspects of this internal reality than does science, which confines itself deliberately and by convention to the study of one very limited class of experiences - the experiences of sense.

To those whose talents are above mediocrity, the highest subjects may be announced. To those who are below mediocrity, the highest subjects may not be announced.

One could count on one's fingers the number of scientists in the entire world who have a general idea of the history and development of their own particular science; there is not one who is really competent as regards sciences other than his own. As science forms an indivisible whole, one may say that there are no longer, strictly speaking, any scientists, but only drudges doing scientific work. . . .

There are two types of poor people, those who are poor together and those who are poor alone. The first are the true poor, the others are rich people out of luck.

And we cannot change this order of things; but what we can do is to acquire stout hearts, worthy of good men, thereby courageously enduring chance and placing ourselves in harmony with Nature.

Custom, then, is the great guide of human life. It is that principle alone which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past. Without the influence of custom, we should be entirely ignorant of every matter of fact beyond what is immediately present to the memory and senses. We should never know how to adjust means to ends, or to employ our natural powers in the production of any effect. There would be an end at once of all action, as well as of the chief part of speculation. Variant (perhaps a paraphrase of this passage): It is not reason which is the guide of life, but custom.

Let us not pretend to doubt in philosophy what we do not doubt in our hearts.

Of the various executive abilities, no one excited more anxious concern than that of placing the interests of our fellow-citizens in the hands of honest men, with understanding sufficient for their stations. No duty is at the same time more difficult to fulfil. The knowledge of character possessed by a single individual is of necessity limited. To seek out the best through the whole Union, we must resort to the information which from the best of men, acting disinterestedly and with the purest motives, is sometimes incorrect.

The regime which is destroyed by a revolution is almost always an improvement on its immediate predecessor, and experience teaches that the most critical moment for bad governments is the one which witnesses their first steps toward reform.

The picture of modern philosophy as centered in epistemology and driven by the desire to ground our representations is so tenacious that some philosophers are prepared to bite the bullet and declare the effort simply wasted. Rorty, for example, finds it easier to reject modern philosophy altogether than to reject the standard accounts of its history. His narrative is more polemical than most, but it's a polemical version of the story told in most philosophy departments in the second half of the twentieth century. The story is one of tortuously decreasing interest. Philosophy, like some people, was prepared to accept boredom in exchange for certainty as it grew to middle age.

Descartes is rightly regarded as the father of modern philosophy primarily and generally because he helped the faculty of reason to stand on its own feet by teaching men to use their brains in place whereof the Bible, on the one hand, and Aristotle, on the other, had previously served.

The existence of the mind-independent environment beyond one's world-simulation is a theoretical inference, not an empirical observation.

One comfort is, that Great Men, taken up in any way, are profitable company. We cannot look, however imperfectly, upon a great man, without gaining something by him. He is the living light-fountain, which it is good and pleasant to be near. The light which enlightens, which has enlightened the darkness of the world; and this not as a kindled lamp only, but rather as a natural luminary shining by the gift of Heaven; a flowing light-fountain, as I say, of native original insight, of manhood and heroic nobleness;-in whose radiance all souls feel that it is well with them.

Behold, a sower went forth to sow; And when he sowed, some seeds fell by the way side, and the fowls came and devoured them up: Some fell upon stony places, where they had not much earth: and forthwith they sprung up, because they had no deepness of earth: And when the sun was up, they were scorched; and because they had no root, they withered away. And some fell among thorns; and the thorns sprung up, and choked them: But other fell into good ground, and brought forth fruit, some an hundredfold, some sixtyfold, some thirtyfold. Who hath ears to hear, let him hear.

The third kind of life is the life of contemplation.
