Thought is only a flash between two long nights, but this flash is everything.

It is truly not the merit of the school if we do not come out selfish. Each sort of corresponding pride and every wind of covetousness, eagerness for office, mechanical and servile officiousness, hypocrisy, etc., is bound as much with extensive knowledge as with elegant, classical education, and since this whole instruction exercises no influence of any sort on our ethical behavior, it thus frequently falls to the fate of being forgotten in the same measure as it is not used: one shakes off the dust of the school.

Everything is the work of imagination, and... all the faculties of the soul can be correctly reduced to pure imagination...

To recognize a difficulty is not to solve it.

The condition of life to which people of the well-to-do classes are accustomed is that of an abundant production of various articles necessary for their comfort and pleasure, and these things are obtained only thanks to the existence of factories and works organized as at present. And, therefore, discussing the improvement of the workers' position, the men of science belonging to the well- to-do classes always have in view only such improvements as will not do away with the system of factory-production and those conveniences of which they avail themselves.

To all this, someone is sure to object that life ought to subject itself to reason, to which we will reply that nobody ought to do what he is unable to do, and life cannot subject itself to reason. "Ought, therefore can," some Kantian will retort. To which we shall demur: "Cannot, therefore ought not." And life cannot submit itself to reason, because the end of life is living and not understanding.

I am not afraid to appeal to the nation at large, to posterity, and still less to that Being Who sees Himself our motives, Who will judge us from His own knowledge of them.

Functional communication is only the outer layer of the one- dimensional universe in which man is trained to target-to translate the negative into the positive so that he can continue to function, reduced but fit and reasonably well. The institutions of free speech and freedom of thought do not hamper the mental coordination with the established reality. What is taking place is a sweeping redefinition of thought itself, of its function and content. The coordination of the individual with his society reaches into those layers of the mind where the very concepts are elaborated which are designed to comprehend the established reality. These concepts are taken from the intellectual tradition and translated into operational terms-a translation which has the effect of reducing the tension between thought and reality by weakening the negative power of thought.

"The will of the nation" is one of those expressions which have been most profusely abused by the wily and the despotic of every age.

If I were to imagine a girl deeply in love and some man who wanted to use all his reasoning powers and knowledge to ridicule her passion, well, there's surely no question of the enamoured girl having to choose between keeping her wealth and being ridiculed. No, but if some extremely cool and calculating man calmly told the young girl, "I will explain to you what love is," and the girl admitted that everything he told her was quite correct, I wonder if she wouldn't choose his miserable common sense rather than her wealth?

He said they that were serious in ridiculous matters would be ridiculous in serious affairs.

Well, he wasn't a relativist. There's a long and complicated story of the rise of a desire for scientific relativism. Part of it may well be simply sort of rage against reason, the fear of the sciences and a kind of total dislike of the arrogance of a great many scientists who say we're finding out the truth about everything-and here [with Kuhn] there was a way to undermine that arrogance.

If your parent is just, revere him; if not, bear with him.

It is the act of an ill-instructed man to blame others for his own bad condition; it is the act of one who has begun to be instructed, to lay the blame on himself; and of one whose instruction is completed, neither to blame another, nor himself.

"Their own strength has betrayed them. They have pulled down Deep Heaven on their heads."

I make known unto thee how He hath provided for the bodily health of us all, by having produced Æsculapius, the Preserver of the universe; and how he hath communicated to us virtue of every kind, by sending down Aphrodite in company with Athene for our guardian; having made it all but a law that no one should use copulation except for the end of generating his like. For this reason truly, according to his revolutions and seasons, do the various vegetable and animal races feel themselves stirred towards the generation of their kind. What need is there to magnify the glory of his rays, and of his light? A night without moon, and without stars, how terrible is it! Let anyone reflect on this, in order that he may estimate how great a blessing is the light we derive from the Sun!

Skills are called hidden treasure as they save like a mother in a foreign country.

Too much consistency is as bad for the mind as it is for the body. Consistency is contrary to nature, contrary to life. The only completely consistent people are the dead. Consistent intellectualism and spirituality may be socially valuable, up to a point; but they make, gradually, for individual death.

Omnipotence and foreknowledge of God, I repeat, utterly destroy the doctrine of 'free-will' ... doubtless it gives the greatest possible offense to common sense or natural reason, that God, Who is proclaimed as being full of mercy and goodness, and so on, should of His own mere will abandon, harden and damn men, as though He delighted in the sins and great eternal torments of such poor wretches. It seems an iniquitous, cruel, intolerable thought to think of God; and it is this that has been such a stumbling block to so many great men down through the ages. And who would not stumble at it? I have stumbled at it myself more than once, down to the deepest pit of despair, so that I wished I had never been made a man.

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.

I accept nothing on authority. A hypothesis must be backed by reason, or else it is worthless.

Given our anthropocentric bias, thinking of non-human vertebrates not just as equivalent in moral status to toddlers or infants, but as though they were toddlers or infants, is a useful exercise. Such reconceptualisation helps correct our lack of empathy for sentient beings whose physical appearance is different from "us". Ethically, the practice of intelligent "anthropomorphism" shouldn't be shunned as unscientific, but embraced insofar as it augments our stunted capacity for empathy. Such anthropomorphism can be a valuable corrective to our cognitive and moral limitations. This is not a plea to be sentimental, simply for impartial benevolence.

Make sure that your religion is a matter between you and God only.

When we are told, in the same tone, that these people will be rewarded in "heaven" for their distress, and that "heaven" is the exact reverse of the earthly order ("the first shall be last"), we distinctly feel how the ressentiment-laden man transfers to God the vengeance he himself cannot wreak on the great. In this way, he can satisfy his revenge at least in imagination, with the aid of an other-worldly mechanism of rewards and punishments.

Looking back we can see how indirectly we know the environment in which nevertheless we live. We can see that the news of it comes to us now fast, now slowly; but that whatever we believe to be a true picture, we treat as if it were the environment itself.

As soon as the generals and the politicos can predict the motions of your mind, lose it. Leave it as a sign to mark the false trail, the way you didn't go. Be like the fox who makes more tracks than necessary, some in the wrong direction. Practice resurrection.

Nothing makes the earth seem so spacious as to have friends at a distance; they make the latitudes and longitudes.

In every stock-jobbing swindle everyone knows that some time or other the crash must come, but every one hopes that it may fall on the head of his neighbour, after he himself has caught the shower of gold and placed it in safety.

No sacrifice is lost for a great ideal!

What is important is that sex was not only a question of sensation and pleasure, of law and interdiction, but also of the true and the false.

Immature love says: "I love you because I need you." Mature love says: "I need you because I love you."

That knowledge which adds greatness to character is knowledge so handled as to transform every phase of immediate experience.

He was often, and much beyond reason, provoked by my failures in cases where success could not have been expected; but in the main his method was right, and it succeeded. I do not believe that any scientific teaching ever was more thorough, or better fitted for training the faculties, than the mode in which logic and political economy were taught to me by my father. Striving, even in an exaggerated degree, to call forth the activity of my faculties, by making me find out everything for myself, he gave his explanations not before, but after, I had felt the full force of the difficulties; and not only gave me an accurate knowledge of these two great subjects, as far as they were then understood, but made me a thinker on both.

How does the light of a star set out and plunge into black eternity in its immortal course? The star dies, but the light never dies; such also is the cry of freedom. Out of the transient encounter of contrary forces which constitute your existence, strive to create whatever immortal thing a mortal may create in this world - a Cry. And this Cry, abandoning to the earth the body which gave it birth, proceeds and labors eternally.

We cannot suppose that an individual's thinking survives bodily death, since that destroys the organization of the brain and dissipates the energy which utilized the brain tracks. God and immortality, the central dogma of the Christian religion, find no support in science. But we in the West have come to think of them as the irreducible minimum of theology. No doubt people will continue to entertain these beliefs, because they are pleasant, just as it is pleasant to think ourselves virtuous and our enemies wicked. But for my part I cannot see any grounds for either. I do not pretend to be able to prove that there is no God. I equally cannot prove Satan is a fiction. The Christian God may exist, so might the Gods of Olympus, Ancient Egypt or Babylon; but no one of these hypotheses is more probable than any other. They lie outside the region of provable knowledge and there is no reason to consider any of them.

A sword by itself does not slay; it is merely the weapon used by the slayer.

Were we directed from Washington when to sow and when to reap, we should soon want bread.

Well both original seizure and subsequent critical discrimination have equal claims, each to its own complete development and must not be forgotten that direct and unreasoned impression comes first. There is such occasions something of the quality of the wind that bloweth where it listeth. Sometimes it comes and sometimes it does not, even in the presence of the same object. It cannot be forced and when it does not arrive it is not wise to seek to recover by direct action the first fine rapture.

What ideas individuals may attach to the term "Millennium" I know not; but I know that society may be formed so as to exist without crime, without poverty, with health greatly improved, with little, if any misery, and with intelligence and happiness increased a hundredfold; and no obstacle whatsoever intervenes at this moment except ignorance to prevent such a state of society from becoming universal.

Much reading has brought upon us a learned barbarism.

Keep cool: it will be all one a hundred years hence.

If the king loves music, there is little wrong in the land.

If the very essence of knowledge changes, at the moment of the change to another essence of knowledge there would be no knowledge, and if it is always changing, there will always be no knowledge, and by this reasoning there will be neither anyone to know nor anything to be known. But if there is always that which knows and that which is known if the beautiful, the good, and all the other verities exist I do not see how there is any likeness between these conditions of which I am now speaking and flux or motion.

The much occupied man has no time for wantonness, and it is an obvious commonplace that the evils of leisure can be shaken off by hard work.

Every man should be protected in his lawful acts, and be certain that no ex post facto law shall punish or endamage him for them. ...The sentiment that ex post facto laws are against natural right, is so strong in the United States, that few, if any, of the State constitutions have failed to proscribe them. The federal constitution indeed interdicts them in criminal cases only; but they are equally unjust in civil as in criminal cases, and the omission of a caution which would have been right, does not justify the doing what is wrong. Nor ought it to be presumed that the legislature meant to use a phrase in an unjustifiable sense, if by rules of construction it can be ever strained to what is just.
