How far down the evolutionary scale shall we go? Shall we eat fish? What about shrimps? Oysters? To answer these questions we must bear in mind the central principle on which our concern for other beings is based. As I said ... the only legitimate boundary to our concern for the interests of other beings is the point at which it is no longer accurate to say that the other being has interests. To have interests, in a strict, nonmetaphorical sense, a being must be capable of suffering or experiencing pleasure. If a being suffers, there can be no moral justification for disregarding that suffering, or for refusing to count it equally with the like suffering of any other being. But the converse of this is also true. If a being is not capable of suffering, or of enjoyment, there is nothing to take into account.

What is not heartrending is superfluous, at least in music.

The pursuit of philosophy is founded on the belief that knowledge is good, even if what is known is painful. A man imbued with the philosophic spirit, whether a professional philosopher or not, will wish his beliefs to be as true as he can make them, and will, in equal measure, love to know and hate to be in error. This principle has a wider scope than may be apparent at first sight.

Nothing can contribute more to peace of soul than the lack of any opinion whatever.

All art is autobiographical; the pearl is the oyster's autobiography.

My mother spoke of Christ to my father, by her feminine and childlike virtues, and, after having borne his violence without a murmur or complaint, gained him at the close of his life to Christ.

Diogenes, in his mud-covered sandals, tramps over the carpets of Aristippus. The cynic pullulated at every corner, and in the highest places. This cynic did nothing but saboter the civilisation of the time. He was the nihilist of Hellenism. He created nothing, he made nothing. His role was to undo - or rather to attempt to undo, for he did not succeed in his purpose. The cynic, a parasite of civilisation, lives by denying it, for the very reason that he is convinced that it will not fail. What would become of the cynic among a savage people where everyone, naturally and quite seriously, fulfils what the cynic farcically considers to be his personal role?

And I must speak plainly. If I were a judge, I would have such a poisonous, syphilitic whore tortured by being broken on the wheel and having her veins lacerated, for it is not to be denied what damage such a filthy whore does to young blood, so that it is unspeakably damaged before it is even fully grown and destroyed in the blood.

This year, or this month, or, more likely, this very day, we have failed to practise ourselves the kind of behaviour we expect from other people.

"For many, abstract thinking is toil; for me, on good days, it is feast and frenzy." (XIV, 24) Abstract thinking a feast? The highest form of human existence? ... "The feast implies: pride, exuberance, frivolity; mockery of all earnestness and respectability; a divine affirmation of oneself, out of animal plenitude and perfection-all obviously states to which the Christian may not honestly say Yes. The feast is paganism par excellence." (WM, 916). For that reason, we might add that thinking never takes place in Christianity. That is to say, there is no Christian philosophy. There is no true philosophy that could be determined anywhere else than from within itself.

Life is not, and death is a dream. Suffering has invented them both as self-justification. Man alone is torn between an unreality and an illusion.

The hardness of God is kinder than the softness of men, and His compulsion is our liberation.

I... believe in the rationalist tradition of a commonwealth of learning, and in the urgent need to preserve this tradition.

Big industry, and the limitless expansion of production which it makes possible, bring within the range of feasibility a social order in which so much is produced that every member of society will be in a position to exercise and develop all his powers and faculties in complete freedom. It thus appears that the very qualities of big industry which, in our present-day society, produce misery and crises are those which, in a different form of society, will abolish this misery and these catastrophic depressions.We see with the greatest clarity: (i) That all these evils are from now on to be ascribed solely to a social order which no longer corresponds to the requirements of the real situation; and (ii) That it is possible, through a new social order, to do away with these evils altogether.

I believe that the advance of science depends upon the free competition of thought, and thus upon freedom, and that it must come to an end if freedom is destroyed (though it may well continue for some time in some fields, especially in technology).

These examples... show that, in whatever proportion of its limbs the Gorilla differs from Man, the other Apes depart still more widely from the Gorilla and that, consequently, such differences of proportion can have no ordinal value.

Raise your eyes and count the small gang of your oppressors who are only strong through the blood they suck from you and through your arms which you lend them unwillingly.

The lowest stage of humanity is experienced when the individual must labour for a small pittance of wages from others.

Lend yourself to others, but give yourself to yourself.

What would really satisfy us would be a God who said of anything we happened to like, "What does it matter so long as they are contented?" We want, in fact, not so much a Father in Heaven as a grandfather in heaven - a senile benevolence who, as they say, "liked to see young people enjoying themselves" and whose plan for the universe was simply that it might be truly said at the end of each day, "a good time was had by all".

Even in the important matter of cranial capacity, Men differ more widely from one another than they do from the Apes; while the lowest Apes differ as much, in proportion, from the highest, as the latter does from Man.

There is little less trouble in governing a private family than a whole kingdom. 

The vicious circle of dread of war which leads the nations to arm themselves for self-protection, with the result that bloated armaments ultimately lead to the war which they were intended to avert, can be broken in either of two conceivable ways. There might arise a unique world power, brought into being by the unification of all those now in possession of weapons, and equipped with the capacity to forbid the lesser and unarmed nations to make war. On the other hand, it may arise by the working of a fate to us still inscrutable which, out of ruin, will disclose a way towards the development of a new human being. To will the discovery of this way would be blind impotence, but those who do not wish to deceive themselves will be prepared for the possibility.

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

Liberating tolerance, then, would mean intolerance against movements from the Right, and toleration of movements from the Left.

The 'public' is a phantom, the phantom of an opinion supposed to exist in a vast number of persons who have no effective interrelation and though the opinion is not effectively present in the units. Such an opinion is spoken of as 'public opinion,' a fiction which is appealed to by individuals and by groups as supporting their special views. It is impalpable, illusory, transient; "'tis here, 'tis there, 'tis gone"; a nullity which can nevertheless for a moment endow the multitude with power to uplift or destroy.

I do not believe that science per se is an adequate source of happiness, nor do I think that my own scientific outlook has contributed very greatly to my own happiness, which I attribute to defecating twice a day with unfailing regularity.

What the public wants is the image of passion, not passion itself.

The faith that stands on authority is not faith.

The difference principle, for example, requires that the higher expectations of the more advantaged contribute to the prospects of the least advantaged.

The Superego, in censoring the unconscious and in implanting conscience, also censors the censor.

How you produce volume after volume the way you do is more than I can conceive. ...But you haven't to forge every sentence in the teeth of irreducible and stubborn facts as I do. It is like walking through the densest brush wood.

The prestige of the Nobel Prize is due to many causes, but in particular to its twofold idealistic and international character: idealistic in that it has been designed for works of lofty inspiration; international in that it is awarded after the production of different countries has been minutely studied and the intellectual balance sheet of the whole world has been drawn up. Free from all other considerations and ignoring any but intellectual values, the judges have deliberately taken their place in what the philosophers have called a community of the mind.

It was not only that I could not become spiteful, I did not know how to become anything; neither spiteful nor kind, neither a rascal nor an honest man, neither a hero nor an insect. Now, I am living out my life in my corner, taunting myself with the spiteful and useless consolation that an intelligent man cannot become anything seriously, and it is only the fool who becomes anything.

From that point, my universe went on crumbling; new cracks appeared all the time. I could see that the pleasant securities of childhood, all of those warm little human emotions, all of those trivial aims and purposes that we allow to rule our lives, were an illusion. We were like sheep munching grass, unaware that the butcher's lorry is already on its way. I got used to living with a deep, underlying feeling of uncertainty that no one around me seemed to share. It was rather like living on death row.

It is precisely those artists and writers who are most inclined to think of their art as the manifestation of their personality who are in fact the most in bondage to public taste.

The ideal subject of totalitarian rule is not the convinced Nazi or the convinced Communist, but people for whom the distinction between fact and fiction (i.e., the reality of experience) and the distinction between true and false (i.e., the standards of thought) no longer exist.

Without will, no conflict: no tragedy among the abulic. Yet the failure of will can be experienced more painfully than a tragic destiny.

The symptom is not only a cyphered message, it is at the same time a way for the subject to organize his enjoyment - that is why, even after the completed interpretation, the subject is not prepared to renounce his symptom.

Morality is not properly the doctrine of how we may make ourselves happy, but how we may make ourselves worthy of happiness.

When Christianity came into the world the task was simply to proclaim Christianity. The same is the case wherever Christianity is introduced into a country the religion of which is not Christianity.

From such honor and such a height of fortune am I, thus fallen to earth, cast down amongst mortals.

Ideas are cheap. It's only what you do with them that counts.

The emptiness of Zen Buddhism... creates a neighborly nearness between things.

The need for novelty is the characteristic of an alienated gorilla.

It's easier to be faithful to a restaurant than it is to a woman.

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

In the natural state no concept of God can arise, and the false one which one makes for himself is harmful. Hence the theory of natural religion can be true only where there is no science; therefore it cannot bind all men together.
