The aspects of things that are most important for us are hidden because of their simplicity and familiarity. (One is unable to notice something - because it is always before one's eyes.) The real foundations of his enquiry do not strike a man at all. Unless that fact has at some time struck him. - And this means: we fail to be struck by what, once seen, is most striking and most powerful.

Take any aspect of the Western inheritance of which our ancestors were proud, and you will find university courses devoted to deconstructing it. Take any positive feature of our political and cultural inheritance, and you will find concerted efforts in both the media and the academy to place it in quotation marks, and make it look like an imposture or a deceit.

No nation keeps its word. A nation is a big, blind worm, following what? Fate perhaps. A nation has no honour, it has no word to keep. ... Hitler is himself the nation. That incidentally is why Hitler always has to talk so loud, even in private conversation - because he is speaking with 78 million voices.

Of all our infirmities, the most savage is to despise our being.

It is too narrow an understanding of production which confines it merely to the making of things. Production includes not merely the making of things, but the bringing of them to the consumer. The merchant or storekeeper is thus as truly a producer as is the manufacturer, or farmer, and his stock or capital is as much devoted to production as is theirs.

Yet its essence was the certitude that his life was not totally at the mercy of chance. Somehow, it was more important than that. This sense of power inside his head - which he could intensify by pulling a face and wrinkling up the muscles of his forehead - aroused a glow of optimism, an expectation of exciting events. He knew that for him, fate held something special in store.

The Pope will make the king believe that three are only one, that the bread he eats is not bread...and a thousand other things of the same kind.

How much education may reconcile young people to pain and sufference, the examples of Sparta do sufficiently shew; and they who have once brought themselves not to think bodily pain the greatest of evils, or that which they ought to stand most in fear of, have made no small advance toward virtue.

For man holds his ground only by surpassing himself, in the same sense in which it is said that one ceases to love if one does not love increasingly everyday.

I am endeavouring to live every day as if it were a complete life.

The application of psychoanalysis to sociology must definitely guard against the mistake of wanting to give psychoanalytic answers where economic, technical, or political facts provide the real and sufficient explanation of sociological questions. On the other hand, the psychoanalyst must emphasize that the subject of sociology, society, in reality consists of individuals, and that it is these human beings, rather than abstract society as such, whose actions, thoughts, and feelings are the object of sociological research.

What we have is a device for producing sentences in response to sentences. But none of these sentences is at all connected to the real world. If one coupled two of these machines and let them play the Imitation Game with each other, then they would go on 'fooling' each other forever, even if the rest of the world disappeared! There is no more reason to regard the machine's talk of apples as referring to real world apples than there is to regard the ant's 'drawing' as referring to Winston Churchill.

The plea of anger or of drunkenness - as having placed the criminal for the moment beyond the control of his reason - relieves him from the charge of premeditated and malicious intent; but a rational legislation will rather provide more severe than milder punishment for such cases, particularly if such a state of mind is habitual with the accused; for a single unlawful act may well constitute an exception from an otherwise blameless life. But a person who pleads, "I habitually get so angry or so drunk as not to be any longer master of my senses!" confesses thereby that he changes himself into a beast on a fixed principle, and that he is, therefore, not fit to live among rational beings.

It is the duty of every patriot to protect his country from its government.

How much good it would do if one could exterminate the human race.

The mechanical mind has a passion for control - of everything except itself. Beyond the control it has won over the forces of nature it would now win control over the forces of society of stating the problem and producing the solution, with social machinery to correspond.

Conflicting intellectual positions may actually come to supplement one another. It is imperative in the present transitional period to make use of the intellectual twilight which dominates our epoch and in which all values and points of view appear in their genuine relativity. We must realize once and for all that the meanings which make up our world are simply an historically determined and continuously developing structure in which man develops, and are in no sense absolute.

To these spurious principles must be added some others of great affinity with them... First, that by which we assume that everything in the universe is done according to the order of nature, which principle by Epicurus was proclaimed without any restriction, and by all other philosophers unanimously with extremely rare exceptions, not to be admitted but from supreme necessity.

The sun provides the moon with its brightness.

It really comes down to parsimony, economy of explanation. It is possible that your car engine is driven by psychokinetic energy, but if it looks like a petrol engine, smells like a petrol engine and performs exactly as well as a petrol engine, the sensible working hypothesis is that it is a petrol engine.

As touching the gods, I do not know whether they exist or not, nor how they are featured; for there is much to prevent our knowing: the obscurity of the subject and the brevity of human life.

All for ourselves, and nothing for other people, seems, in every age of the world, to have been the vile maxim of the masters of mankind.

The authority of science ... promotes and encourages the activity of observing, comparing, measuring and ordering the physical characteristics of human bodies.... Cartesian epistemology and classical ideals produced forms of rationality, scientificity and objectivity that, though efficacious in the quest for truth and knowledge, prohibited the intelligibility and legitimacy of black equality.... In fact, to "think" such an idea was to be deemed irrational, barbaric or mad.

"Do not die that we may not die," the dead cry out within you. "We had no time to enjoy the women we desired; be in time, sleep with them! We had no time to turn our thoughts into deeds; turn them into deeds! We had no time to grasp and to crystallize the face of our hope; make it firm!" ... But you must choose with care whom to hurl down again into the chasms of your blood, and whom you shall permit to mount once more into the light and the earth.

In a quarrel for earth, turn not to earth.

And now, at half-past ten o'clock, I hear the cockerels crow in Hubbard's barns, and morning is already anticipated. It is the feathered, wakeful thought in us that anticipates the following day.

I wished, by treating Psychology like a natural science, to help her to become one.

There is more to a science fiction story than the science it contains.

Man grows used to everything, the scoundrel.

...racial hatred is not a natural phenomenon innate in man. It is the product of ideologies. But even if such a thing as a natural and inborn hatred between various races existed, it would not render social cooperation futile and would not invalidate Ricardo's theory of association. Social cooperation has nothing to do with personal love or with a general commandment to love one another. People do not cooperate under the division of labor because they love or should love one another. They cooperate because this best serves their own interests. Neither love nor charity nor any other sympathetic sentiments but rightly understood selfishness is what originally impelled man to adjust himself to the requirements of society, to respect the rights and freedoms of his fellow men and to substitute peaceful collaboration for enmity and conflict.

It has been observed that missiles and projectiles describe a curved path of some sort; however no one has pointed out the fact that this path is a parabola. But this and other facts, not few in number or less worth knowing, I have succeeded in proving; and what I consider more important, there have been opened up to this vast and most excellent science, of which my work is merely the beginning, ways and means by which other minds more acute than mine will explore its remote corners.

All urgent calls he shall hear at once, but never put off; for when postponed, they will prove too hard or impossible to accomplish.

Great joys, why do they bring us sadness? Because there remains from these excesses only a feeling of irrevocable loss and desertion which reaches a high degree of negative intensity. At such moments, instead of a gain, one keenly feels loss. sadness accompanies all those events in which life expends itself. its intensity is equal to its loss. Thus death causes the greatest sadness.

When angry, count ten before you speak; if very angry, an hundred.

Whether or not there exists a solution to problems troubles only a minority; that the emotions have no outcome, lead to nothing, vanish into themselves - that is the great unconscious drama, the affective insolubility everyone suffers without even thinking about it.

I am a mariner of Odysseus with heart of fire but with mind ruthless and clear.

Economics is on the side of humanity now.

It is difficult, it is impossible to believe that the Good Lord - "Our Father" - had a hand in the scandal of creation. Everything suggests that He took no part in it, that it proceeds from a god without scruples, a feculent god. Goodness does not create, lacking imagination; it takes imagination to put together a world, however botched. At the very least, there must be a mixture of good and evil in order to produce an action or a work.

The detour to ideality leads to coinciding with oneself, that is, to certainty, which remains the guide and guarantee of the whole spiritual adventure of being.

Because of the way that myth takes it for granted that miracles are always happening, the waking life of a mythically inspired people the ancient Greeks, for instance more closely resembles a dream than it does the waking world of a scientifically disenchanted thinker.

Men have superior strength of body; but were it not for mistaken notions of beauty, women would acquire sufficient to enable them to earn their own subsistence, the true definitions of independence; and to bear those bodily inconveniences and exertions that are requisite to strengthen the mind. Let us then, by being allowed to take the same exercise as boys, not only during infancy, but youth, arrive at perfection of body, that we may know how far the nation superiority of man extends . For what reason or virtue can be expected from a creature when the seed-time of life is neglected? None; did not the winds of heaven casually scatter many useful seeds in fallow ground.

Science, ever since the time of the Arabs, has had two functions: (1) to enable us to know things, and (2) to enable us to do things.

Human intuitions are systematically biased. Evolutionary psychology explains how our moral intuitions and the rationalisations they spawn have been shaped by millennia of natural selection to maximise the inclusive fitness of our genes, not to track the welfare of other sentient beings impartially conceived. Many human cultures have found nothing intuitively wrong with aggressive warfare, slavery, wife-beating, infanticide or female genital mutilation. Ultimately, folk morality is a doomed enterprise as hopeless as folk physics. A mature posthuman ethics, I'd argue, must be committed to the well-being of all sentient life; and mature posthuman technology offers the means to deliver that commitment.

Is it not a noble farce, wherein kings, republics, and emperors have for so many ages played their parts, and to which the whole vast universe serves for a theatre?

Nobody really thinks who does not abstract from that which is given, who does not relate the facts to the factors which have made them, who does not - in his mind - undo the facts. Abstractness is the very life of thought, the token of its authenticity.

Nothing is wholly obvious without becoming enigmatic. Reality itself is too obvious to be true.
