But among all the discoveries and corrections probably none has resulted in a deeper influence on the human spirit than the doctrine of Copernicus.... Possibly mankind has never been demanded to do more, for considering all that went up in smoke as a result of realizing this change: a second Paradise, a world of innocence, poetry and piety: the witness of the senses, the conviction of a poetical and religious faith. No wonder his contemporaries did not wish to let all this go and offered every possible resistance to a doctrine which in its converts authorized and demanded a freedom of view and greatness of thought so far unknown indeed not even dreamed of.

It is clear that the causal nexus is not a nexus at all.

This is the worst trait of minds rendered arrogant by prosperity, they hate those whom they have injured.

If melodiously piping flutes sprang from the olive, would you doubt that a knowledge of flute-playing resided in the olive? And what if plane trees bore harps which gave forth rhythmical sounds? Clearly you would think in the same way that the art of music was possessed by plane trees. Why, then, seeing that the universe gives birth to beings that are animate and wise, should it not be considered animate and wise itself?

Though the managing ourselves well in this part of our behavior has the name good-breeding, as if a peculiar effect of education; yet... young children should not be much perplexed about it... Teach them humility, and to be good-natur'd, if you can, and this sort of manners will not be wanting; civility being in truth nothing but a care not to shew any slighting or contempt of any one in conversation.

In science, as in the playing card experiment, novelty emerges only with difficulty, manifested by resistance, against a background provided by expectation.

The greatest of faults, I should say, is to be conscious of none.

He laid it down as a maxim, that monarchy was the basis of all good government and the nearer to monarchy any government approached, the more perfect it was, and vice versa; and he certainly in his wildest moments, never had so far forgotten the nature of government, as to argue that we ought to wish for a constitution that we could alter at pleasure, and change like a dirty shirt. He was by no means anxious for a monarchy with a dash of republicanism to correct it. But the French constitution was the exact opposite of the English in every thing, and nothing could be so dangerous as to set it up to the view of the English, to mislead and debauch their minds.

Anxiety destroys scale, and suffering makes us lose perspective.

We seek and offer ourselves to be gulled.

Originality is a thing we constantly clamour for, and constantly quarrel with; as if, observes our author himself, any originality but our own could be expected to content us! In fact all strange thing are apt, without fault of theirs, to estrange us at first view, and unhappily scarcely anything is perfectly plain, but what is also perfectly common.

No rational argument will have a rational effect on a man who does not want to adopt a rational attitude.

I dare affirm in knowledge of nature, that a little natural philosophy, and the first entrance into it, doth dispose the opinion to atheism; but on the other side, much natural philosophy and wading deep into it, will bring about men's minds to religion; wherefore atheism every way seems to be combined with folly and ignorance, seeing nothing can can be more justly allotted to be the saying of fools than this, "There is no God" Of Atheism.

It's not about telling people how to be, outside of supporting ideals that teach us what to avoid.

Never give way to melancholy; resist it steadily, for the habit will encroach.

All relationships of people to each other rest, as a matter of course, upon the precondition that they know something about each other. The merchant knows that his correspondent wants to buy at the lowest price and to sell at the highest price. The teacher knows that he may credit to the pupil a certain quality and quantity of information. Within each social stratum the individual knows approximately what measure of culture he has to presuppose in each other individual.

There are hardly any truths upon which we always remain agreed, and still fewer objects of pleasure which we do not change every hour, I do not know whether there is a means of giving fixed rules for adapting discourse to the inconstancy of our caprices.

Fame and tranquility can never be bedfellows.

To make an end of all things on Earth, and our Planetical System of the World, he (God) need but put out the Sun.

Perhaps misguided moral passion is better than confused indifference.

Never say, and never take seriously anyone who says, "I cannot believe that so-and-so could have evolved by gradual selection". I have dubbed this kind of fallacy "the Argument from Personal Incredulity". Time and again, it has proven the prelude to an intellectual banana-skin experience.

The familial union presents as well a mixture of inconvenient ages and characters that inhibit conversation. Morality engenders a frigid atmosphere, as in all places where it reigns.

The jingoes and war speculators are filling the air with the sentimental slogan of hypocritical nationalism, "America for Americans," "America first, last, and all the time."

My own sense of how to behave in a simulation has more traditional roots in the theory of perception. I've long believed that each of us lives in an egocentric simulation of the world run by the mind/brain. Since the zombies of each (waking) simulation have sentient real world counterparts, one should treat them as though they were real. Nonetheless as an angst-ridden teenager, my dawning acceptance of an inferential realist theory of perception made me feel as if I'd been condemned to solitary confinement for life. The sense of loneliness was indescribable. Naïve realism is better for one's mental health.

The progress of human knowledge depends on maintaining that touch of scepticism even about the most "unquestionable" truths. A century ago, Darwin's theory of evolution by natural selection was regarded as scientifically unshakeable; today, most biologists have their reservations about it. Fifty years ago, Freud's sexual theory of neurosis was accepted by most psychiatrists; today, it is widely recognized that his methods were highly questionable. At the turn of this century, a scientist who questioned Newton's theory of gravity would have been regarded as insane; twenty years later, it had been supplanted by Einstein's theory, although, significantly, few people actually understood it. It seems perfectly conceivable that our descendants of the twenty-second century will wonder how any of us could have been stupid enough to have been taken in by Darwin, Freud or Einstein.

He that is without sin among you, let him first cast a stone at her.

Humanity unceasingly strives forward from a lower, more partial and obscure understanding of life to one more general and more lucid. And in this, as in every movement, there are leaders - those who have understood the meaning of life more clearly than others - and of those advanced men there is always one who has in his words and life, manifested this meaning more clearly, accessibly, and strongly than others. This man's expression ... with those superstitions, traditions, and ceremonies which usually form around the memory of such a man, is what is called a religion. Religions are the exponents of the highest comprehension of life ... within a given age in a given society ... a basis for evaluating human sentiments. If feelings bring people nearer to the religion's ideal ... they are good, if these estrange them from it, and oppose it, they are bad.

Every time you make a choice you are turning the central part of you, the part of you that chooses, into something a little different from what it was before. And taking your life as a whole, with all your innumerable choices, all your life long you are slowly turning this central thing either into a heavenly creature or into a hellish creature: either into a creature that is in harmony with God, and with other creatures, and with itself, or else into one that is in a state of war and hatred with God, and with its fellow-creatures, and with itself. To be the one kind of creature is heaven: that is, it is joy and peace and knowledge and power. To be the other means madness, horror, idiocy, rage, impotence, and eternal loneliness. Each of us at each moment is progressing to the one state or the other.

Trantor could win even such a war, but perhaps not without paying a price that would make victory only a pleasanter name for defeat.

In former times the chief method of justifying the use of violence and thereby infringing the law of love was by claiming a divine right for the rulers: the Tsars, Sultans, Rajahs, Shahs, and other heads of states. But the longer humanity lived the weaker grew the belief in this peculiar, God-given right of the ruler. That belief withered in the same way and almost simultaneously in the Christian and the Brahman world, as well as in Buddhist and Confucian spheres, and in recent times it has so faded away as to prevail no longer against man's reasonable understanding and the true religious feeling. People saw more and more clearly, and now the majority see quite clearly, the senselessness and immorality of subordinating their wills to those of other people just like themselves, when they are bidden to do what is contrary not only to their interests but also to their moral sense.

Conscience is deceived by the social. Our supplementary energy (imaginative) is to a great extent taken up with the social. It has to be detached from it. That is the most difficult of detachments.

Gather together in your heart all terrors, recompose all details. Salvation is a circle; close it!

Popular presentation today is all too often that which puts the mob in a position to talk about something without understanding it.

Before making a decision the first thing to do - don't get worked up. For everything happens according to the nature of all things, and in a short time you'll be nobody and nowhere even as the great emperors Hadrian and Augustus are now. The next thing to do - consider carefully the task at hand for what it is, while remembering that your purpose is to be a good human being. Get straight to doing what nature requires of you, and speak as you see most just and fitting - with kindness, modesty, and sincerity.

Science is a cemetery of dead ideas, even though life may issue from them.

Try as I will, I don't see what might exist...

He who is subjected to a field of visibility, and who knows it, assumes responsibility for the constraints of power; he makes them play spontaneously upon himself; he inscribes in himself the power relation in which he simultaneously plays both roles; he becomes the principle of his own subjection.

Anger is a momentary madness so control your passion or it will control you.

Nothing earthly succeeds by ignoring heaven, nothing heavenly by ignoring the earth.
