If a person loves only one other person and is indifferent to all others, his love is not love but a symbiotic attachment, or an enlarged egotism.

Let me have none of your Popish stuff! Get away with you, good morning.

Since therefore, as well those degrees of heat that are not painful, as those that are, can exist in a thinking substance; may we not conclude that external bodies are absolutely incapable of any degree of heat whatsoever?

The reason that people take selfies is not narcissism. Rather, it is inner emptiness. There is no meaning to stabilize the ego. Faced with its inner emptiness, the ego constantly produces itself.

Life is one long struggle in the dark.

The growth of the mind is the widening of the range of consciousness, and ... each step forward has been a most painful and laborious achievement.

Great abuses in the world are begotten, or, to speak more boldly, all the abuses of the world are begotten, by our being taught to be afraid of professing our ignorance, and that we are bound to accept all things we are not able to refute: we speak of all things by precepts and decisions. The style at Rome was that even that which a witness deposed to having seen with his own eyes, and what a judge determined with his most certain knowledge, was couched in this form of speaking: "it seems to me." They make me hate things that are likely, when they would impose them upon me as infallible.

Since my world picture approximates reality only crudely, I cannot aspire to optimize anything; at most, I can aim at satisficing. Searching for the best can only dissipate scarce cognitive resources; the best is the enemy of the good.

If not reason, then the devil.

The utility of a science which enables men to take cognizance of the travellers on the mind's highway, and excludes those disorderly interlopers, verbal fallacies, needs but small attestation. Its searching penetration by definition alone, before which even mathematical precision fails, would especially commend it to those whom the abstruseness of the study does not terrify, and who recognise the valuable results which must attend discipline of mind. Like a medicine, though not a panacea for every ill, it has the health of the mind for its aim, but requires the determination of a powerful will to imbibe its nauseating yet wholesome influence: it is no wonder therefore that puny intellects, like weak stomachs, abhor and reject it.

I cannot call this Shakspeare a "Sceptic," as some do; his indifference to the creeds and theological quarrels of his time misleading them. No: neither unpatriotic, though he says little about his Patriotism; nor sceptic, though he says little about his Faith. Such "indifference" was the fruit of his greatness withal: his whole heart was in his own grand sphere of worship (we may call it such); these other controversies, vitally important to other men, were not vital to him.

The original thinking force of the universe progresses and develops itself in all possible determinations of which it is capable, just as the other original natural forces progress and assume all possible configurations. I am a particular determination of the formative force, like the plant; a particular determination of the peculiar motive force, like the animal; and in addition to this a determination of the thinking force: and the union of these three basic forces into one force, into one harmonious development, is the distinguishing characteristic of my species.

It is not easy for any of us to stop measuring the world against the standard of Europe, but the concept of the multitude requires it of us. It is a challenge. Embrace it.

Heaven and earth shall pass away, but my words shall not pass away.

Until the seventeenth century there was no concept of evidence with which to pose the problem of induction!

One recognizes one's course by discovering the paths that stray from it.

The man who says that the world is a machine has really advanced no further than to say that he is so well satisfied with the analogy that he is through with searching any further.

Neither art nor wisdom may be attained without learning.

Where children are, there is a golden age.

I heard what you were saying. You - you know nothing of my work. You mean my whole fallacy is wrong. How you ever got to teach a course in anything is totally amazing.

If you want to influence him at all, you must do more than merely talk to him ; you must fashion him, and fashion him in such a way that he simply cannot will otherwise than you wish him to will.

Jews are angry and brutish people, vile and vulgar men, slaves worthy of the yoke [Talmudism] which you bear... Go, take back your books and remove yourselves from me. [ The Talmud ] taught the Jews to steal the goods of Christians, to regard them as savage beasts, to push them over the precipice... to kill them with impunity and to utter every morning the most horrible imprecations against them.

What concerns me most here are the ways in which contemporary voices considered to be leftist have abandoned the philosophical ideas that are central to any left-wing standpoint: a commitment to universalism over tribalism, a firm distinction between justice and power, and a belief in the possibility of progress.

A religious symbol does not rest on any opinion. And error belongs only with opinion. One would like to say: This is what took place here; laugh, if you can.

Christ is not valued at all unless He be valued above all.

Men became scientific because they expected law in Nature; and they expected law in Nature because they believed in a Legislator.

I would say here something that was heard from an ecclesiastic of the most eminent degree [probably Caesar Baronius]: "The intention of the Holy Ghost is to teach us how one goes to heaven, not how heaven goes.

There was very little that prevented the vandalism of 1793 from suddenly producing a second revolution as marvelous as the first was horrible. The whole human race was approaching its release; the civilized, barbarian, and savage order would have disappeared forever if the Convention, which trampled down all prejudices, had not bowed down before the only one that had to be destroyed, the institution of marriage.

Kings and philosophers shit, and so do ladies.

Each the herald is who wrote His rank, and quartered his own coat. There is no king nor sovereign state That can fix a hero's rate.

When you are criticising the philosophy of an epoch, do not chiefly direct your attention to those intellectual positions which its exponents feel it necessary explicitly to defend. There will be some fundamental assumptions which adherents of all the variant systems within the epoch unconsciously presuppose. Such assumptions appear so obvious that people do not know what they are assuming because no other way of putting things has ever occurred to them. With these assumptions a certain limited number of types of philosophic systems are possible, and this group of systems constitutes the philosophy of the epoch.

By this means all knowledge degenerates into probability; and this probability is greater or less, according to our experience of the veracity or deceitfulness of our understanding, and according to the simplicity or intricacy of the question.

In the mid nineteenth century, the typical murderer was a drunken illiterate; a hundred years later the typical murderer regards himself as a thinking man.

The end of history is, alas, also the end of the dustbins of history. There are no longer any dustbins for disposing of old ideologies, old regimes, old values. Where are we going to throw Marxism, which actually invented the dustbins of history? (Yet there is some justice here since the very people who invented them have fallen in.) Conclusion: if there are no more dustbins of history, this is because History itself has become a dustbin. It has become its own dustbin, just as the planet itself is becoming its own dustbin.

The distance between oneself and other persons and other species can fall anywhere on a continuum. Even for other persons the understanding of what it is like to be them is only partial, and when one moves to species very different from oneself, a lesser degree of partial understanding may still be available. The imagination is remarkably flexible. My point, however, is not that we cannot know what it is like to be a bat. I am not raising that epistemological problem. My point is rather that even to form a conception of what it is like to be a bat and a fortiori to know what it is like to be a bat, one must take up the bat's point of view.

Media, by altering the environment, evoke in us unique ratios of sense perception...When these ratios change, men change.

In particular, it is certainly wrong to condemn poor old Homo sapiens as the only species to kill his own kind, the only inheritor of the mark of Cain, and similar melodramatic charges. Whether a naturalist stresses the violence or the restraint of animal aggression depends partly on the kinds of animals he is used to watching, and partly on his evolutionary preconceptions-Lorenz is, after all, a 'good of the species' man. Even if it has been exaggerated, the gloved fist view of animal fights seems to have at least some truth. Superficially this looks like a form of altruism. The selfish gene theory must face up to the difficult task of explaining it. Why is it that animals do not go all out to kill rival members of their species at every possible opportunity?

[M]y father's rejection of all that is called religious belief, was not, as many might suppose, primarily a matter of logic and evidence: the grounds of it were moral, still more than intellectual. He found it impossible to believe that a world so full of evil was the work of an Author combining infinite power with perfect goodness and righteousness.

When a war breaks out, people say: "It's too stupid; it can't last long." But though the war may well be "too stupid," that doesn't prevent its lasting. Stupidity has a knack of getting its way; as we should see if we were not always so much wrapped up in ourselves.

Pyrrhus, when his friends congratulated to him his victory over the Romans under Fabricius, but with great slaughter of his own side, said to them, "Yes; but if we have such another victory, we are undone".

No man treats a motorcar as foolishly as he treats another human being. When the car will not go, he does not attribute its annoying behaviour to sin; he does not say, "You are a wicked motorcar, and I shall not give you any more petrol until you go." He attempts to find out what is wrong and to set it right. An analogous way of treating human beings is, however, considered to be contrary to the truths of our holy religion.

My parents, both of whom spoke Russian fluently, made no effort to teach me Russian, but insisted on my learning English as rapidly and as well as possible. They even set about learning English themselves, with reasonable, but limited, success.In a way, I am sorry. It would have been good to know the language of Pushkin, Tolstoy, and Dostoevski. On the other hand, I would not have been willing to let anything get in the way of the complete mastery of English. Allow me my prejudice: surely there is no language more majestic than that of Shakespeare, Milton, and the King James Bible, and if I am to have one language that I know as only a native can know it, I consider myself unbelievably fortunate that it is English.

It is not enough to be wrong, one must also be polite.

Genes and culture have co-evolved. But crudely, natural selection "designed" male human primates to hunt nonhumans and build coalitions of other male human primates in order to wage territorial wars of aggression. Nature didn't design us to become a scientific community and collaborate to overcome aging. It's difficult to imagine that any human enemy could inflict such gruesome damage on the victims as growing old. The ravages of aging strike down combatants and civilians alike. So the trillions of dollars that humans currently spend on ways to harm and kill each other ("defence") would be more fruitfully spent on defeating our common enemy. We should work together to build a "Triple S" civilisation of superlongevity, superhappiness and superintelligence.

Genius is always sufficiently the enemy of genius by over influence.

To say that man is a compound of strength and weakness, light and darkness, smallness and greatness, is not to indict him, it is to define him.
