Reading after a certain age diverts the mind too much from its creative pursuits. Any man who reads too much and uses his own brain too little falls into lazy habits of thinking, just as the man who spends too much time in the theater is tempted to be content with living vicariously instead of living his own life.

Human vanity cherishes the absurd notion that our species is the final goal of evolution.

The two ways of contemplation are not unlike the two ways of action commonly spoken of by the ancients: the one plain and smooth in the beginning, and in the end impassable; the other rough and troublesome in the entrance, but after a while fair and even. So it is in contemplation: If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts he shall end in certainties.

Being is only Being for Dasein.

Let there be freedom from perturbations with respect to the things which come from the external cause; and let there be justice in the things done by virtue of the internal cause, that is, let there be movement and action terminating in this, in social acts, for this is according to thy nature.

A reproach can only hurt if it hits the mark. Whoever knows that he does not deserve a reproach can treat it with contempt.

I've always been careful never to predict anything that had not already happened.

In future, nerve cell responsiveness to naturally occurring endogenous opioids can be increased via receptor enrichment in the brain too. In principle, we can modulate their lifelong "overexpression", intermittently heightened (or gently diminished) by whatever kinds of personal and environmental contingencies we judge fit. Both functionally and anatomically, our reward pathways can be made "bigger and better". But intelligent emotional self-mastery will involve re-engineering the mind-brain so we derive the most intense rewards from activities we deem most lastingly worthwhile: i.e. prioritising our higher-order desires over legacy first-order appetites. Natural selection has "encephalised" our emotions to benefit our genes. Rational agents can "re-encephalise" our emotions to benefit us.

To have grazed every form of failure, including success.

There are two ways in which a science develops; in response to problems which is itself creates, and in response to problems that are forced on it from the outside.

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

Don't you know that a good and excellent person does nothing for the sake of appearances, but only for the sake of having acted right?

Greater fates gain greater rewards.

Before you embark on a journey of revenge, dig two graves.

Only the dead have seen the end of war.

We Shall Naturally look round in vain the macrophysical world for acausal events, for the simple reason that we cannot imagine events that are connected non-causally and are capable of a non-causal explanation. But that does not mean that such events do not exist... The so-called "scientific view of the world" based on this can hardly be anything more than a psychologically biased partial view which misses out all those by no means unimportant aspects that cannot be grasped statistically.

Democratic and aristocratic states are not in their own nature free. Political liberty is to be found only in moderate governments; and even in these it is not always found. It is there only when there is no abuse of power. But constant experience shows us that every man who has power is inclined to abuse it; he goes until he finds limits. Is it not strange, though true, to say that virtue itself has need of limits?.To prevent this abuse, it is necessary that, by the arrangement of things, power shall stop power. A government may be so constituted, as no man shall be compelled to do things to which the law does not oblige him, nor forced to abstain from things which the law permits.

The whole life of the upper classes is a constant inconsistency. The more delicate a man's conscience is, the more painful this contradiction is to him.

What does it mean to have a god? or, what is God? Answer: A god means that from which we are to expect all good and to which we are to take refuge in all distress, so that to have a God is nothing else than to trust and believe Him from the [whole] heart; as I have often said that the confidence and faith of the heart alone make both God and an idol. If your faith and trust be right, then is your god also true; and, on the other hand, if your trust be false and wrong, then you have not the true God; for these two belong together faith and God. That now, I say, upon which you set your heart and put your trust is properly your god.

Natural science is throughout either a pure or an applied doctrine of motion.

In a book called Symbolism, Its Meaning and Effect, Whitehead points out that perception is usually a matter of symbols, just like language; I say I see a book when I actually see a red oblong. The Transactionists (who have been influenced by Whitehead rather than Husserl) take this one stage further, and point out that when I 'perceive' something, I am actually making a bet with myself that what I perceive is what I think it is. In order to act and live at all, I have to make these bets; I cannot afford to make absolutely certain that things are what I think they are. But this means that we should not take our perceptions at face value, any more than Nietzsche was willing to take philosophy at its face value; we must allow for prejudice and distortion.

The cruelest lies are often told in silence. A man may have sat in a room for hours and not opened his teeth, and yet come out of that room a disloyal friend or a vile calumniator. And how many loves have perished because, from pride, or spite, or diffidence, or that unmanly shame which withholds a man from daring to betray emotion, a lover, at the critical point of the relation, has but hung his head and held his tongue?

I wouldn't give an astrologer the time of day.

All our problems are caused by forgetting what lives within us, and we sell our souls for the "bowl of stew" of bodily satisfactions.

I think that the philosopher must, for his own purposes, carry methodological strictness to an extreme when he is investigating and pursuing his truths, but when he is ready to enunciate them and give them out, he ought to avoid the cynical skill with which some scientists, like a Hercules at the fair, amuse themselves by displaying to the public the biceps of their technique.

Christianity set itself the goal of fulfilling man's unattainable desires, but for that very reason ignored his attainable desires. By promising man eternal life, it deprived him of temporal life, by teaching him to trust in God's help it took away his trust in his own powers; by giving him faith in a better life in heaven, it destroyed his faith in a better life on earth and his striving to attain such a life. Christianity gave man what his imagination desires, but for that very reason failed to give him what he really and truly desires.

Everybody knows that the same sum of money is of much greater value to a poor man that to a rich one. Give £10 a year to the man who has but £10 a year, you double his income, and you nearly double his enjoyments. Add £10 more, you do not add to his enjoyments so much as you did by the first £10. The third £10 is less valuable than the second, and the fourth less valuable than the third. To the possessor of £1,000 a year the addition of £10 would be scarcely perceptible; to the possessor of £10,000 it would not be worth slooping for.The richer a man is the less he is benefited by any further addition to his income. The man of £4,000 a year has four times the income of the man who has but £1,000; but does anybody suppose that he has four times the happiness?

A just system must generate its own support.

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.

Verily I say unto you, I have not found so great faith, no, not in Israel. And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven. But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth.

By what aberration has suicide, the only truly normal action, become the attribute of the flawed?

Wherever a man comes, there comes revolution. The old is for slaves.

"Everything is both a trap and a display; the secret reality of the object is what the Other makes of it."

A clash of doctrines is not a disaster - it is an opportunity.

I think that when friendship and perception of kinship ruled everything, no one killed any creature, because people thought the other animals were related to them.

It is a great force, and a great fortune, to be able to live without any ambition whatever. I aspire to it, but the very fact of so aspiring still participates in ambition.

Fashion is something barbarous, for it produces innovation without reason and imitation without benefit.

Classical political economy nearly touches the true relation of things, without, however,consciously formulating it. This it cannot so long as it sticks in its bourgeois skin.

The real pioneers in ideas, in art and in literature have remained aliens to their time, misunderstood and repudiated.

I am obliged to confess that I do not regard the abolition of slavery as a means of warding off the struggle of the two races in the Southern states. The Negroes may long remain slaves without complaining; but if they are once raised to the level of freemen, they will soon revolt at being deprived of almost all their civil rights; and as they cannot become the equals of the whites, they will speedily show themselves as enemies.

Since the only things we remember are humiliations and defeats, what is the use of all the rest?

Whatever can be done another day can be done today.

Those distinct substances, which concretes generally either afford, or are made up of, may, without very much inconvenience, be called the elements or principles of them.

Sooner or later, each desire must encounter its lassitude: its truth . . .

Depression is a narcissistic malady.

But what all the violence of the feudal institutions could never have effected, the silent and insensible operation of foreign commerce and manufactures gradually brought about.

Physicians have this advantage: the sun lights their success and the earth covers their failures.
