As we speak cruel time is fleeing. Seize the day, believing as little as possible in the morrow.

Prejudice is an opinion without judgement.

Each generation is a filter, a sieve; good genes tend to fall through the sieve into the next generation; bad genes tend to end up in bodies that die young or without reproducing.

Those who keep the masses of men in subjection by exercising force and cruelty deprive them at once of two vital foods, liberty and obedience; for it is no longer within the power of such masses to accord their inner consent to the authority to which they are subjected. Those who encourage a state of things in which the hope of gain is the principal motive take away from men their obedience, for consent which is its essence is not something which can be sold.

Freedom's possibility is not the ability to choose the good or the evil. The possibility is to be able. In a logical system, it is convenient to say that possibility passes over into actuality. However, in actuality it is not so convenient, and an intermediate term is required. The intermediate term is anxiety, but it no more explains the qualitative leap than it can justify it ethically. Anxiety is neither a category of necessity nor a category of freedom; it is entangled freedom, where freedom is not free in itself but entangled, not by necessity, but in itself.

The scientific attitude of mind involves a sweeping away of all other desires in the interests of the desire to know-it involves suppression of hopes and fears, loves and hates, and the whole subjective emotional life, until we become subdued to the material, able to see it frankly, without preconceptions, without bias, without any wish except to see it as it is, and without any belief that what it is must be determined by some relation, positive or negative, to what we should like it to be, or to what we can easily imagine it to be.

There's a Bible on that shelf there. But I keep it next to Voltaire - poison and antidote.

Under the natural course of things each citizen tends towards his fittest function. Those who are competent to the kind of work they undertake, succeed, and, in the average of cases, are advanced in proportion to their efficiency; while the incompetent, society soon finds out, ceases to employ, forces to try something easier, and eventually turns to use.

The wave of the future is coming and there is no fighting it.

The game of science is, in principle, without end. He who decides one day that scientific statements do not call for any further test, and that they can be regarded as finally verified, retires from the game.

He seldom or never spoke except actually to convey an idea. Measured by quantity of words, he was a talker of fully average copiousness; by extent of meaning communicated, he was the most copious I have listened to. How in few sentences he would sketch you off an entire biography, an entire object or transaction, keen, clear, rugged, genuine, completely rounded In! His words came direct from the heart by the inspiration of the moment.

When we are lulled into somnolence by lack of challenge every molehill tends to become a mountain, every minor inconvenience an intolerable imposition. For a self-chosen reality tends to become a prison. The factors that protect and insulate civilized man can easily end by suffocating him unless he possesses a high degree of self-discipline, the 'highly developed vital sense' that Shaw speaks of. And since clever and sensitive people are inclined to lack self-discipline, a high degree of culture usually involves a high degree of pessimism. This is what has happened to Western civilisation over the past two centuries. It explains why so many distinguished artists, writers and musicians have taken such a negative view of the human situation.

Science does not know its debt to imagination.

The object of this Essay is to explain as clearly as I am able grounds of an opinion which I have held from the very earliest period when I had formed any opinions at all on social political matters, and which, instead of being weakened or modified, has been constantly growing stronger by the progress reflection and the experience of life. That the principle which regulates the existing social relations between the two sexes - the legal subordination of one sex to the other - is wrong itself, and now one of the chief hindrances to human improvement; and that it ought to be replaced by a principle of perfect equality, admitting no power or privilege on the one side, nor disability on the other.

Wisdom, virtue, morality, all these have fallen out of fashion: everybody worships at the shrine of commerce.

Ideas, aspirations, and objectives that, by their content, transcend the established universe of discourse and action are either repelled or reduced to terms of this universe.

What we call objective reality is, in the last analysis, what is common to many thinking beings, and could be common to all; this common part, we shall see, can only be the harmony expressed by mathematical laws. It is this harmony... which is the sole objective reality, the only truth we can attain; and when I add that the universal harmony of the world is the source of all beauty, it will be understood what price we should attach to the slow and difficult progress which little by little enables us to know it better.

The first consequence of the principle of bounded rationality is that the intended rationality of an actor requires him to construct a simplified model of the real situation in order to deal with it. He behaves rationally with respect to this model, and such behavior is not even approximately optimal with respect to the real world. To predict his behavior we must understand the way in which this simplified model is constructed, and its construction will certainly be related to his psychological properties as a perceiving, thinking, and learning animal.

I am not indeed ignorant that certain over-wise people will call these legends "old wives' fables," and not worth listening to; but I think, for my part, that in such matters it is better to believe the testimony of nations than of those witty individuals, whose little soul is acute indeed, but has a clear insight into no one thing.

If you let people follow their feelings, they will be able to do good. This is what is meant by saying that human nature is good.

The speaker with whom I was most struck, though I dissented from nearly every word he said, was Thirlwall, the historian, since Bishop of St. David's, then a Chancery barrister, unknown except by a high reputation for eloquence acquired at the Cambridge Union before the era of Austin and Macaulay. His speech was in answer to one of mine. Before he had uttered ten sentences, I set him down as the best speaker I had ever heard, and I have never since heard any one whom I placed above him.

The covetous man is ever in want.

The deepest thinking is humble. It is only concerned that the flame of truth which it keeps alive should burn with the strongest and purest heat; it does not trouble about the distance to which its brightness penetrates.

I had obtained some distinction, and felt myself of some importance, before the desire of distinction and of importance had grown into a passion: and little as it was which I had attained, yet having been attained too early, like all pleasures enjoyed too soon, it had made me blasé and indifferent to the pursuit. Thus neither selfish nor unselfish pleasures were pleasures to me. And there seemed no power in nature sufficient to begin the formation of my character anew, and create in a mind now irretrievably analytic, fresh associations of pleasure with any of the objects of human desire.

It is clearly absurd to say that if you go on adding atoms together until they have fused into a complex molecule, that molecule will become capable of self-reproduction. It is like saying that a skyscraper is more capable of reproduction than a bungalow. And suppose life did come into being through some accidental interaction of molecules, sun and cosmic rays; why should it not be content to rest passively? Why should it have been possessed of a desire to persist and evolve?

Last words are for fools who haven't said enough.

Detachment from the world as an attachment to the ego... Who can realize the detachment in which you are as far away from yourself as you are from the world?

For a large class of cases - though not for all - in which we employ the word meaning it can be explained thus: the meaning of a word is its use in the language.

I think no virtue goes with size; The reason of all cowardice Is, that men are overgrown, And, to be valiant, must come down To the titmouse dimension.

I don't believe in an afterlife, so I don't have to spend my whole life fearing hell, or fearing heaven even more. For whatever the tortures of hell, I think the boredom of heaven would be even worse.

Nostalgia, more than anything, gives us the shudder of our own imperfection.

All the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerers (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudible business of mankind, and the most heroick of virtues. By these steps unnatural cruelty is planted in us; and what humanity abhors, custom reconciles and recommends to us, by laying it in the way to honour. Thus, by fashioning and opinion, that comes to be a pleasure, which in itself neither is, nor can be any.

Not because Socrates said so,... I look upon all men as my compatriots.

"They would say," he answered, "that you do not fail in obedience through lack of love, but have lost love because you never attempted obedience."

Organizations and institutions permit stable expectations to be formed by each member of the group as to the behavior of the other members under specified conditions.

For the truth is that our doctrines are usually only the justification a posteriori of our conduct, or else they are our way of trying to explain that conduct to ourselves.

As far as men go, it is not what they are that interests me, but what they can become.

Those of our pleasures which come most rarely give the greatest delight.

When a man no longer confuses himself with the definition of himself that others have given him, he is at once universal and unique. He is universal by virtue of the inseparability of his organism from the cosmos. He is unique in that he is just this organism and not any stereotype of role, class, or identity assumed for the convenience of social communication.

Every questioning is a seeking. Every seeking takes its direction beforehand from what is sought. Questioning is a knowing search for beings in their thatness and whatness.

If I knew of something that could serve my nation but would ruin another, I would not propose it to my prince, for I am first a man and only then a Frenchman, because I am necessarily a man, and only accidentally am I French.

Do I write out of love to men? No, I write because I want to procure for my thoughts an existence in the world; and, even if I foresaw that these thoughts would deprive you of your rest and your peace, even if I saw the bloodiest wars and the fall of many generations springing up from this seed of thought - I would nevertheless scatter it. Do with it what you will and can, that is your affair and does not trouble me.

Non-operational ideas are non-behavioral and subversive. The movement of thought is stopped at barriers which appear as the limits of Reason itself.

The evolutionary urge drives man to seek for intenser forms of fulfillment, since his basic urge is for more life, more consciousness, and this contentment has an air of stagnation that the healthy mind rejects. (This recognition lies at the centre of my own 'outsider theory': that there are human beings to whom comfort means nothing, but whose happiness consists in following an obscure inner-drive, an 'appetite for reality'.)

It is the courage to make a clean breast of it in the face of every question that distinguishes the philosopher. He must be like Sophocles' Oedipus, who, seeking enlightenment concerning his terrible fate, pursues his indefatigable inquiry even though he divines that appalling horror awaits him in the answer. But most of us carry with us the Jocasta in our hearts, who begs Oedipus, for God's sake, not to inquire further.

It is a sore thing to have laboured along and scaled the arduous hilltops, and when all is done, find humanity indifferent to your achievement. Hence physicists condemn the unphysical; financiers have only a superficial toleration for those who know little of stocks; literary persons despise the unlettered; and people of all pursuits combine to disparage those who have none. But though this is one difficulty of the subject, it is not the greatest. You could not be put in prison for speaking against industry, but you can be sent to Coventry for speaking like a fool. The greatest difficulty with most subjects is to do them well; therefore, please to remember this is an apology. It is certain that much may be judiciously argued in favour of diligence; only there is something to be said against it, and that is what, on the present occasion, I have to say.
