Every attempt to refer chemical questions to mathematical doctrines must be considered, now and always, profoundly irrational, as being contrary to the nature of the phenomena. . . . but if the employment of mathematical analysis should ever become so preponderant in chemistry (an aberration which is happily almost impossible) it would occasion vast and rapid retrogradation....

I knew a parson who frightened his congregation terribly by telling them that the second coming was very imminent indeed, but they were much consoled when they found that he was planting trees in his garden.

Eros and depression are opposites.

Power is the near neighbour of necessity.

Lifetime is a child at play, moving pieces in a game.

An appeal to his alarm is never a good plan to rid oneself of a spirited young man.

Impurity is caused by attitude, not events.

But what of the poor Ghosts who never get into the omnibus at all?' 'Everyone who wishes it does. Never fear. There are only two kinds of people in the end: those who say to God, "Thy will be done," and those to whom God says, in the end, "Thy will be done." All that are in Hell, choose it. Without that self-choice there could be no Hell. No soul that seriously and constantly desires joy will ever miss it. Those who seek find. To those who knock it is opened.

But when they have realized that it [society] rejects them forever, they themselves assume the ostracism of which they are victims so as not to leave the initiative to their oppressors.

In the presence of the total reality upon which our conduct is founded, our knowledge is characterized by peculiar limitations and aberrations. We cannot say in principle that "error is life and knowledge is death," because a being involved in persistent errors would continually act wide of the purpose, and would thus inevitably perish.

A thing is important if anyone think it important.

A life without adventure is likely to be unsatisfying, but a life in which adventure is allowed to take whatever form it will is sure to be short.

He who knows himself properly can very soon learn to know all other men. It is all reflection.

It may indeed be doubted, whether butcher's meat is any where a necessary of life. Grain and other vegetables, with the help of milk, cheese, and butter, or oil, where butter is not to be had, it is known from experience, can, without any butcher's meat, afford the most plentiful, the most wholesome, the most nourishing, and the most invigorating diet.

Jehovah, Allah, the Trinity, Jesus, Buddha, are names for a great variety of human virtues, human mystical experiences, human remorses, human compensatory fantasies, human terrors, human cruelties. If all men were alike, all the world would worship the same God.

As there were black swans, though civilized people had existed for three thousand years on the earth without meeting with them...The uniform experience, therefore, of the inhabitants of the known world, agreeing in a common result, without one known instance of deviation from that result, is not always sufficient to establish a general conclusion.

The unity is brought about by force.

I am not adverting here to the alleged privacy of experience to its possessor. The point of view in question is not one accessible only to a single individual. Rather it is a type. It is often possible to take up a point of view other than one's own, so the comprehension of such facts is not limited to one's own case. There is a sense in which phenomenological facts are perfectly objective: one person can know or say of another what the quality of the other's experience is. They are subjective, however, in the sense that even this objective ascription of experience is possible only for someone sufficiently similar to the object of ascription to be able to adopt his point of view - to understand the ascription in the first person as well as in the third, so to speak. The more different from oneself the other experiencer is, the less success one can expect with this enterprise.

The method of the science not being practiced much nowadays, except what logic prescribes to all sciences generally, that fitted for the peculiar nature of metaphysics being simply ignored, it is no wonder that those who everlastingly turn the Sisyphean stone of this inquiry do not seem so far to have made much progress. Though here I neither can nor will expatiate upon so important and extensive a subject, I shall briefly shadow forth what constitutes no despicable part of this method, namely, the infection between sensuous and intellectual cognition, not only as creeping in on those incautious in the application of principles, but even producing spurious principles under the appearance of axioms.

Tell me what to avoid, what to seek, by what studies to strengthen my tottering mind, how I may rebuff the waves that strike me abeam and drive me from my course, by what means I may be able to cope with all my evils, and by what means I can be rid of the calamities that have plunged in upon me and those into which I myself have plunged. Teach me how to bear the burden of sorrow without a groan on my part, and how to bear prosperity without making others groan; also, how to avoid waiting for the ultimate and inevitable end, and to beat a retreat of my own free will, when it seems proper to me to do so.

I finished the Iliad to-day... I never admired the old fellow so much, or was so strongly moved by him. What a privilege genius like his enjoys! I could not tear myself away. I read the last five books at a stretch during my walk to-day, and was at last forced to turn into a bypath, lest the parties of walkers should see me blubbering for imaginary beings, the creations of a ballad-maker who has been dead two thousand seven hundred years. What is the power and glory of Caesar and Alexander to that? Think what it would be to be assured that the inhabitants of Monomotapa would weep over one's writings.

Above all, every relation must be considered as suspicious, which depends in any degree upon religion, as the prodigies of Livy: And no less so, everything that is to be found in the writers of natural magic or alchemy, or such authors, who seem, all of them, to have an unconquerable appetite for falsehood and fable.

The End of History was never linked to a specifically American model of social or political organisation. Following Alexandre Kojève, the Russian-French philosopher who inspired my original argument, I believe that the European Union more accurately reflects what the world will look like at the end of history than the contemporary United States. The EU's attempt to transcend sovereignty and traditional power politics by establishing a transnational rule of law is much more in line with a "post-historical" world than the Americans' continuing belief in God, national sovereignty, and their military.

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.

Science has adapted itself entirely to the wealthy classes and accordingly has set itself to heal those who can afford everything, and it prescribes the same methods for those who have nothing to spare.

Some will ask, what about weak natures, must they not be protected? Yes, but to be able to do that, it will be necessary to realize that education of children is not synonymous with herdlike drilling and training. If education should really mean anything at all, it must insist upon the free growth and development of the innate forces and tendencies of the child. In this way alone can we hope for the free individual and eventually also for a free community, which shall make interference and coercion of human growth impossible.

First we have to believe, and then we believe.

Any man more right than his neighbors constitutes a majority of one.

You must learn all things, both the unshaken heart of persuasive truth, and the opinions of mortals in which there is no true warranty.

The multiplication of our kind borders on the obscene; the duty to love them, on the preposterous.

The basis of science is the empirical method, which uses the senses to build up a picture of the world; but science tells us that our senses have evolved to help us get by, not to show us the world as it is. Science is only a systematic examination of our impressions, and in the end all each of us has left are our own sensations ... The end-result of the empirical method, then, is that each individual is left alone with their own experiences. We can escape this solitude, Balfour suggested, only if we accept that there is a divine mind.

There is a strong affinity between the forces of empire and a politics of hate that justifies policies of domination and exclusion. So long as people's attention is focused on fear and hatred of foreigners or members of a particular religious group, such as Muslims, they are distracted from organizing to deal with the system of institutional domination and exploitation that is the real source of their insecurity.

Materials are indifferent, but the use which we make of them is not a matter of indifference.

Thus I progressed on the surface of life, in the realm of words as it were, never in reality. All those books barely read, those friends barely loved, those cities barely visited, those women barely possessed! I went through the gestures out of boredom or absent-mindedness. Then came the human beings, they wanted to cling, but there was nothing to cling to, and that was unfortunate for them. As for me, I forgot. I never remembered anything but myself.

With deep roots Ether plunged into earth.

Be not the slave of Words.

Ministers become a sort of miniature kings in their turn. Though they have the greatest opportunity of observing the impotence and unmeaningness of the character, they envy it. It is their trade perpetually to extol the dignity and importance of the master they serve; and men cannot long anxiously endeavor to convince others of the truth of any proposition without becoming half convinced themselves.

A man's character is formed by the Odes, developed by the Rites and perfected by music.

The history of science, like the history of all human ideas, is a history of irresponsible dreams, of obstinacy, and of error. But science is one of the very few human activities - perhaps the only one - in which errors are systematically criticized and fairly often, in time, corrected. This is why we can say that, in science, we often learn from our mistakes, and why we can speak clearly and sensibly about making progress there.

The characters of self-restrained officials are exceedingly careful and just and conservative, but they lack keenness and a certain quick and active boldness. The courageous natures, on the other hand, are deficient in justice and caution in comparison with the former, but excel in boldness of action; and unless both these qualities are present it is impossible for a state to be entirely prosperous in public and private matters.

It is the failing of a certain literature to believe that life is tragic because it is wretched. Life can be magnificent and overwhelming that is its whole tragedy. Without beauty, love, or danger it would be almost easy to live. And M. Sartre's hero does not perhaps give us the real meaning of his anguish when he insists on those aspects of man he finds repugnant, instead of basing his reasons for despair on certain of man's signs of greatness. The realization that life is absurd cannot be an end, but only a beginning. This is a truth nearly all great minds have taken as their starting point. It is not this discovery that is interesting, but the consequences and rules of action drawn from it.

The greater part of human activity is designed to make permanent those experiences and joys which are only lovable because they are changing.

Saying is one thing, doing another.

The lack of objectivity, as far as foreign nations are concerned, is notorious. From one day to another, another nation is made out to be utterly depraved and fiendish, while one's own nation stands for everything that is good and noble. Every action of the enemy is judged by one standard - every action of oneself by another. Even good deeds by the enemy are considered a sign of particular devilishness, meant to deceive us and the world, while our bad deeds are necessary and justified by our noble goals which they serve.

Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality.

Aion is a child at play, gambling; a child's is the kingship. Telesphorus traverses the dark places of the world, like a star flashing from the deep, leading the way to the gates of the sun and the land of dreams.

A very few, as heroes, patriots, martyrs, reformers in the great sense, and men, serve the State with their consciences also, and so necessarily resist it for the most part; and they are commonly treated by it as enemies.

My own book Women, Race and Class was one of many that were published during that era, including, to name only a few, This Bridge Called My Back, edited by Gloria Anzaldúa and Cherrie Moraga, the work of bell hooks and Michelle Wallace, and the anthology All the Women Are White, All the Blacks Are Men, but Some of Us Are Brave: Black Women's Studies. So behind this concept of intersectionality is a rich history of struggle. A history of conversations among activists within movement formations, and with and among academics as well.

Reading the Socratic dialogues one has the feeling: what a frightful waste of time! What's the point of these arguments that prove nothing and clarify nothing?

World War I a railway war of centralization and encirclement. World War II a radio war of decentralization concluded by the Bomb. World War III a TV guerrilla war with no divisions between civil and military fronts.
