Antisthenes ... was asked on one occasion what learning was the most necessary, and he replied, "To unlearn one's bad habits."

Those who cavalierly reject the Theory of Evolution, as not adequately supported by facts, seem quite to forget that their own theory is supported by no facts at all. Like the majority of men who are born to a given belief, they demand the most rigorous proof of any adverse belief, but assume that their own needs none.

So long as antimilitarists propose no substitute for war's disciplinary function, no moral equivalent of war, analogous, as one might say, to the mechanical equivalent of heat, so long they fail to realize the full inwardness of the situation.

To have failed in everything, always, out of a love of discouragement.

In conclusion, then, no satisfactory interpretation of quantum mechanics exists today. The questions posed by the confrontation between the Copenhagen interpretation and the hidden variable theorists go to the very foundations of microphysics, but the answers given by hidden variable theorists and Copenhagenists are alike unsatisfactory. Human curiosity will not rest until those questions are answered, but whether they will be answered by conceptual innovations within the framework of the present theory or only within the framework of an as yet unforeseen theory is unknown. The first step toward answering them has been attempted here. It is the modest but essential step of becoming clear on the nature and magnitude of the difficulties.

All his life he [the American] jumps into the train after it has started and jumps out before it has stopped; and he never once gets left behind, or breaks a leg.

I think it is not helpful to apply Darwinian language too widely. Conquest of nation by nation is too distant for Darwinian explanations to be helpful. Darwinism is the differential survival of self-replicating genes in a gene pool, usually as manifested by individual behaviour, morphology, and phenotypes. Group selection of any kind is not Darwinism as Darwin understood it nor as I understand it. There is a very vague analogy between group selection and conquest of a nation by another nation, but I don't think it's a very helpful analogy. So I would prefer not to invoke Darwinian language for that kind of historical interpretation.

I want death to find me planting my cabbages.

No man is liberated from fear who dare not see his place in the world as it is; no man can achieve the greatness of which he is capable until he has allowed himself to see his own littleness.

To resign oneself or to blow out one's brains, that is the choice one faces at certain moments. In any case, the only real dignity is that of exclusion.

It is true that may hold in these things, which is the general root of superstition; namely, that men observe when things hit, and not when they miss; and commit to memory the one, and forget and pass over the other.

I remembered the way out suggested by a great princess when told that the peasants had no bread: "Well, let them eat cake".

That the human mind has a certain order of possible progress, in which some things must precede others, an order which governments and public instructors can modify to some, but not to an unlimited extent: that all questions of political institutions are relative, not absolute, and that different stages of human progress not only will have, but ought to have, different institutions: That government is always either in the hands, or passing into the hands, of whatever is the strongest power in society, and that what this power is, does not depend on institutions, but institutions on it: That any general theory or philosophy of politics supposes a previous theory of human progress, and that this is the same thing with a philosophy of history.

Logical empiricism holds the view, notwithstanding some its assertions, that the forms of knowledge and consequently the relations of man to nature and to other men never change. According to rationalism, too, all subjective and objective potentialities are rooted in insights which the individual already possesses, but rationality uses existing objects as well as the active inner striving and ideas of man to construct standards for the future. In this regard, it is not so closely associated with the present order as is empiricism.

I am against a League war in present circumstances, because the anti-League powers are strong. The analogy is not King v. Barons, but the War of the Roses. If the League were strong enough I should favour sanctions, because the effect would suffice, or the war would be short and small. The whole question is quantitative.

Power tends to reduce openness... Power tries to solidify and stabilize its position by eradicating spaces open to play, or incalculable spaces.

I think all the great religions of the world - Buddhism, Hinduism, Christianity, Islam, and Communism - both untrue and harmful. It is evident as a matter of logic that, since they disagree, not more than one of them can be true. With very few exception, the religions which a man accepts is that of the community in which he lives, which makes it obvious that the influence of environment is what has led him to accept the religion in question.

True Religion does not manifest itself outwardly, and impels man to no course of external conduct which he would not otherwise have adopted, but that it only completes his true In ward Being and Dignity. It is neither an Action, nor an incentive to Action, but a Thought:-it is LIGHT, and the One True Light, which bears within it all Life and all the forms of Life, and pervades their innermost substance. Once arisen, this Light flows on spontaneously forever, spreading itself forth without term or limit;-and it is as idle to bid it shine, as it would be to address such a command to the material sun when it stands in the noon-day heavens. It does this without our bidding; and if it shine not, then has it not arisen. At its uprising, Darkness, and the brood of spectres and phantasms which are born of Darkness, vanish of themselves.

A on his lips and not-A in his heart.

... the fight against suffering must be considered a duty, while the right to care for the happiness of others must be considered a privilege confined to the close circle of their friends. ... Pain, suffering, injustice, and their prevention, these are the eternal problems of public morals, the 'agenda' of public policy ...

To-day the Enlightenment ideal has been changed into a reality; not only in legislation, which is the mere framework of public life, but in the heart of every individual, whatever his ideas may be, and even if he be a reactionary in his ideas, that is to say, even when he attacks and castigates institutions by which those rights are sanctioned.... The sovereignty of the unqualified individual, of the human being as such, generically, has now passed from being a juridical idea or ideal to be a psychological state inherent in the average man. And note this, that when what was before an ideal becomes a component part of reality, it inevitably ceases to be an ideal. The prestige and the magic that are attributes of the ideal are volatilised.

I have entered on an enterprise which is without precedent, and will have no imitator. I propose to show my fellows a man as nature made him, and this man shall be myself.

What interest, zest, or excitement can there be in achieving the right way, unless we are enabled to feel that the wrong way is also a possible and a natural way, - nay, more, a menacing and an imminent way? And what sense can there be in condemning ourselves for taking the wrong way, unless we need have done nothing of the sort, unless the right way was open to us as well? I cannot understand the willingness to act, no matter how we feel, without the belief that acts are really good and bad.

What we want is not freedom but its appearances. It is for these simulacra that man has always striven. And since freedom, as has been said, is no more than a sensation, what difference is there between being free and believing ourselves free?

No sound ought to be heard in the church but the healing voice of Christian charity.

When I found myself regarded as respectable, I began to wonder what sins I had committed. I must be very wicked, I thought. I began to engage in the most uncomfortable introspection. Interview with Irwin Ross, September 1957;If there were a God, I think it very unlikely that he would have such an uneasy vanity as to be offended by those who doubt his existence.

No one should try to live if he has not completed his training as a victim.

Do not take part in the council, unless you are called.

But let there be no misunderstanding: it is not that a real man, the object of knowledge, philosophical reflection or technological intervention, has been substituted for the soul, the illusion of theologians. The man described for us, whom we are invited to free, is already in himself the effect of a subjection more profound than himself. A 'soul' inhabits him and brings him to existence, which is itself a factor in the mastery that power exercises over the body. The soul is the effect and instrument of a political anatomy; the soul is the prison of the body.

In the tragedies of the early seventeenth century, madness too provided the dénouement, but it did so in liberating the truth. It still opened onto language, to a renewed form of speech, that of explanation and of the real regained. The most it could ever be was the penultimate moment of tragedy. Not the closing moment, as in Andromaque, where no truth appears, other than, in Delirium, the truth of a passion that finds its fullest, most perfect expression in madness.

So long as men worship the Caesars and Napoleons, Caesars and Napoleons will duly rise and make them miserable.

Moderation is the spirit of castrated narrow-mindedness.

Rational mechanics must be the science of the motions which result from any forces, and of the forces which are required for any motions, accurately propounded and demonstrated. For many things induce me to suspect, that all natural phenomena may depend upon some forces by which the particles of bodies are either drawn towards each other, and cohere, or repel and recede from each other: and these forces being hitherto unknown, philosophers have pursued their researches in vain. And I hope that the principles expounded in this work will afford some light, either to this mode of philosophizing, or to some mode which is more true.

Logical analysis applied to mental phenomenon shows that there is but one law of mind, namely that ideas tend to spread continuously and to affect certain others which stand to them in a peculiar relation of affectibility. In this spreading they lose intensity, and especially the power of affecting others, but gain generality and become welded with other ideas.

Virtue is the same for a man and for a woman.

In fact, the real problem with the thesis of A Genealogy of Morals is that the noble and the aristocrat are just as likely to be stupid as the plebeian. I had noted in my teens that major writers are usually those who have had to struggle against the odds -- to "pull their cart out of the mud," as I put it -- while writers who have had an easy start in life are usually second rate -- or at least, not quite first-rate. Dickens, Balzac, Dostoevsky, Shaw, H. G. Wells, are examples of the first kind; in the twentieth century, John Galsworthy, Graham Greene, Evelyn Waugh, and Samuel Beckett are examples of the second kind. They are far from being mediocre writers; yet they tend to be tinged with a certain pessimism that arises from never having achieved a certain resistance against problems.

Weisinger, a couple of years ago, made up the following story: "Isaac Asimov was asked how Superman could fly faster than the speed of light, which was supposed to be an absolute limit. To this Asimov replied, 'That the speed of light is a limit is a theory; that Superman can travel faster than light is a fact.'"

No Man is wise at all Times, or is without his blind Side.

Life itself is but the shadow of death, and souls departed but the shadows of the living: All things fall under this name. The Sun itself is but the dark simulacrum, and the light but the shadow of God.

For every man the world is as fresh as it was at the first day, and as full of untold novelties for him who has the eyes to see them.

Haikus allow the whole world to appear within things.

The Creation was the first act of sabotage.

If there is anything unique about the human animal it is that it has the ability to grow knowledge at an accelerating rate while being chronically incapable of learning from experience. Science and technology are cumulative, whereas ethics and politics deal with recurring dilemmas. Whatever they are called, torture and slavery are universal evils; but these evils cannot be consigned to the past like redundant theories in science. They return under different names: torture as enhanced interrogation techniques, slavery as human trafficking. Any reduction in universal evils is an advance in civilization. But, unlike scientific knowledge, the restraints of civilized life cannot be stored on a computer disc. They are habits of behaviour, which once broken are hard to mend. Civilization is natural for humans, but so is barbarism.

The education of the common people requires, perhaps, in a civilized and commercial society, the attention of the public more than that of people of some rank and fortune.

Of all Discourse, governed by desire of Knowledge, there is at last an End, either by attaining, or by giving over.
