..Whenever it ceases to be true that mankind, as a rule, prefer themselves to others, and those nearest to them to those more remote, from that moment Communism is not only practicable, but the only defensible form of society...

There slowly grew up in me an unshakable conviction that we have no right to inflict suffering and death on another living creature unless there is some unavoidable necessity for it, and that we ought all of us to feel what a horrible thing it is to cause suffering and death out of mere thoughtlessness. And this conviction has influenced me only more and more strongly with time. I have grown more and more certain that at the bottom of our heart we all think this, and that we fail to acknowledge it because we are afraid of being laughed at by other people as sentimentalists, though partly also because we allow our best feelings to get blunted. But I vowed that I would never let my feelings get blunted, and that I would never be afraid of the reproach of sentimentalism.

The life of man is of no greater importance to the universe than that of an oyster.

Is Man so different from any of these Apes that he must form an order by himself? Or does he differ less from them than they differ from one another, and hence must take his place in the same order with them?

Pure Mathematics is the class of all propositions of the form "p implies q," where p and q are propositions containing one or more variables, the same in the two propositions, and neither p nor q contains any constants except logical constants. And logical constants are all notions definable in terms of the following: Implication, the relation of a term to a class of which it is a member, the notion of such that, the notion of relation, and such further notions as may be involved in the general notion of propositions of the above form. In addition to these, mathematics uses a notion which is not a constituent of the propositions which it considers, namely the notion of truth.

Phenomenology is not a philosophy; it is a philosophical method, a tool. It is like an adjustable spanner that can be used for dismantling a refrigerator or a car, or used for hammering in nails, or even for knocking somebody out.

Architecture worth great attention. As we double our numbers every 20 years we must double our houses. Besides we build of such perishable materials that one half of our houses must be rebuilt in every space of 20 years. So that in that term, houses are to be built for three fourths of our inhabitants. It is then among the most important arts: and it is desireable to introduce taste into an art which shews so much.

A man must be a little mad if he does not want to be even more stupid.

Peace be with you. Receive my peace unto yourselves. Beware that no one lead you astray saying Lo here or lo there! For the Son of Man is within you. Follow after Him! Those who seek Him will find Him. Go then and preach the gospel of the Kingdom. Do not lay down any rules beyond what I appointed you, and do not give a law like the lawgiver lest you be constrained by it.

Most people, at a crisis, feel more loyalty to their nation than to their class.

... in such a matter he would never have been guided by his first thoughts (which would probably have been right) nor even by his twenty-first (which would have at least been explicable). Beyond doubt he would have prolonged deliberation till his hundred-and-first; and they would be infallibly and invincibly wrong. This is what always happens to the deliberations of a simple man who thinks he is a subtle one.

Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence. Faith is belief in spite of, even perhaps because of, the lack of evidence.

Time, which is the author of authors.

The entire universe is perfused with signs, if it is not composed exclusively of signs.

It is not, what a lawyer tells me I may do; but what humanity, reason, and justice, tell me I ought to do.

Fire is the best of servents; but what a master!

To love truth for truth's sake is the principal part of human perfection in this world, and the seed-plot of all other virtues.

The physical change in the thickness of walls since the Middle Ages could be shown in a diagram. In the fourteenth century each house was a fortress. Man spent the major portion of his day in them, in secret and well-defended solitude. That solitude, working on the soul hour after hour, forged it, like a transcendent blacksmith, into a compact and forceful character. Under its treatment, man consolidated his individual destiny and sallied forth with impunity, never yielding to the contamination from the public. It is only in isolation that we gain, almost automatically, a certain discrimination in ideas, desires, longings, that we learn which are ours, and which are anonymous, floating in the air, falling on us like dust in the street.

One may observe, that men of all persuasions confine the word persecution, and all the ill ideas of injustice and violence which belong to it, solely to those severities which are exercised upon themselves, or upon the party they are inclined to favour. Whatever is inflicted upon others, is a just punishment upon obstinate impiety, and not a restraint upon conscientious differences.

I have no hesitation in saying that although the American woman never leaves her domestic sphere and is in some respects very dependent within it, nowhere does she enjoy a higher station. And if anyone asks me what I think the chief cause of the extraordinary prosperity and growing power of this nation, I should answer that it is due to the superiority of their women.

Clichés, stock phrases, adherence to conventional, standardized codes of expression and conduct have the socially recognized function of protecting us against reality.

We have lost, being born, as much as we shall lose, dying. Everything.

Many receive advice, few profit by it.

If anything is certain, it is that I myself am not a Marxist

The Americans' "open-mindedness", which is sometimes cited in their favor, is the other side of their interior formlessness. The same goes for their "individualism". Individualism and personality are not the same: the one belongs to the formless world of quantity, the other to the world of quality and hierarchy. The Americans are the living refutation of the Cartesian axiom, "I think, therefore I am": Americans do not think, yet they are. The American "mind", puerile and primitive, lacks characteristic form and is therefore open to every kind of standardization.

Men never do good unless necessity drives them to it; but when they are free to choose and can do just as they please, confusion and disorder become rampant.

The telling of jokes is an art of its own, and it always rises from some emotional threat. The best jokes are dangerous, and dangerous because they are in some way truthful.

There is in fact a manly and legitimate passion for equality that spurs all men to wish to be strong and esteemed. This passion tends to elevate the lesser to the rank of the greater. But one also finds in the human heart a depraved taste for equality, which impels the weak to want to bring the strong down to their level, and which reduces men to preferring equality in servitude to inequality in freedom.

Our colleges ought to have lit up in us a lasting relish for the better kind of man, a loss of appetite for mediocrities, and a disgust for cheapjacks. We ought to smell, as it were, the difference of quality in men and their proposals when we enter the world of affairs about us.

This they do in the service of an imaginary science; and, like the astrologers and soothsayers whom they have succeeded, cast up their eyes to the clouds, and speak in immense, unsubstantiated images and similes, in deeply misleading metaphors and allegories, and make use of hypnotic formulae with little regard for experience, or rational argument, or tests of proven reliability. Thereby they throw dust in their own eyes as well as in ours, obstruct our vision of the real world, and further confuse an already sufficiently bewildered public about the relations of morality to politics, and about the nature and methods of the natural sciences and historical studies alike.

Be not the slave of Words.

The hopes of the right-minded may be realized, those of fools are impossible.

There is probably no more abused a term in the history of philosophy than "representation," and my use of this term differs both from its use in traditional philosophy and from its use in contemporary cognitive psychology and artificial intelligence.... The sense of "representation" in question is meant to be entirely exhausted by the analogy with speech acts: the sense of "represent" in which a belief represents its conditions of satisfaction is the same sense in which a statement represents its conditions of satisfaction. To say that a belief is a representation is simply to say that it has a propositional content and a psychological mode.

Psychoanalysis will be entirely discredited one of these days, no doubt about it. Which will not keep it from destroying our last vestiges of naivete. After psychoanalysis, we can never again be innocent.

There are no whole truths; all truths are half-truths. It is trying to treat them as whole truths that plays the devil.

In the pursuit of truth we must beware of being misled by terms which we do not rightly understand. That is the chief point. Almost all philosophers utter the caution; few observe it.

Whether, then, all ought not immediately to discontinue and renounce it, with grief and abhorrence? Should not every society bear testimony against it, and account obstinate persisters in it bad men, enemies to their country, and exclude them from fellowship; as they often do for much lesser faults?

That the state is an entity and in fact the decisive entity rests upon its political character.

The needs of the soul can for the most part be listed in pairs of opposites which balance and complete one another. The human soul has need of equality and of hierarchy. Equality is the public recognition, effectively expressed in institutions and manners, of the principle that an equal degree of attention is due to the needs of all human beings. Hierarchy is the scale of responsibilities. Since attention is inclined to direct itself upwards and remain fixed, special provisions are necessary to ensure the effective compatibility of equality and hierarchy.

The characteristic feature of militarism is not the fact that a nation has a powerful army or navy. It is the paramount role assigned to the army within the political structure. Even in peacetime the army is supreme; it is the predominant factor in political life. The subjects must obey the government as soldiers must obey their superiors. Within a militarist community there is no freedom; there are only obedience and discipline.

I feel awe of the gods, I love, I revere, I venerate them, and in short have precisely the same feelings towards them as one would have towards kind masters or teachers or fathers or guardians or any beings of that sort.

When I was 4 years old ... I dreamt that I'd been eaten by a wolf, and to my great surprise I was in the wolf's stomach and not in heaven.

I have often felt a bitter sorrow at the thought of the German people, which is so estimable in the individual and so wretched in the generality. A comparison of the German people with other peoples arouses a painful feeling, which I try to overcome in every possible way.

Martyrs create faith, faith does not create martyrs.

I know every numbskull will babble on about "black man," "maneater," "chance," and "retrospective interpretation," in order to banish something terribly inconvenient that might sully the familiar picture of childhood innocence. Ah, these good, efficient, healthy-minded people, they always remind me of those optimistic tadpoles who bask in a puddle in the sun, in the shallowest of waters, crowding together and amiably wriggling their tails, totally unaware that the next morning the puddle will have dried up and left them stranded. On a phallic dream he had as a young child.

Sixty years ago I knew everything. Now I know nothing. Education is a progressive discovery of our own ignorance.

For a man petticoat government is the limit of insolence.

Do not shorten the morning by getting up late, or waste it in unworthy occupations or in talk; look upon it as the quintessence of life, as to a certain extent sacred. Evening is like old age: we are languid, talkative, silly. Each day is a little life: every waking and rising a little birth, every fresh morning a little youth, every going to rest and sleep a little death.
