Obscenity is whatever happens to shock some elderly and ignorant magistrate.

An individual may perceive a way of life, or a method of social organisation, by which more of the desires of mankind could be satisfied than under the existing method. If he perceives truly, and can persuade men to adopt his reform, he is justified. Without rebellion, mankind would stagnate, and injustice would be irremediable.

Science may set limits to knowledge, but should not set limits to imagination.

There is much pleasure to be gained from useless knowledge.

I am ashamed of belonging to the species Homo Sapiens...You & I may be thankful to have lived in happier times - you more than I, because you have no children.

It is said (I do not know with what truth) that a certain Hindu thinker believed the earth to rest upon an elephant. When asked what the elephant rested upon, he replied that it rested upon a tortoise. When asked what the tortoise rested upon, he said, "I am tired of this. Suppose we change the subject." This illustrates the unsatisfactory character of the First-Cause argument.

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

A life without adventure is likely to be unsatisfying, but a life in which adventure is allowed to take whatever form it will is sure to be short.

The secret of happiness is to face the fact that the world is horrible, horrible, horrible.

The observer, when he seems to himself to be observing a stone, is really, if physics is to be believed, observing the effects of the stone upon himself.

As a philosopher, if I were speaking to a purely philosophic audience I should say that I ought to describe myself as an Agnostic, because I do not think that there is a conclusive argument by which one prove that there is not a God. On the other hand, if I am to convey the right impression to the ordinary man in the street I think that I ought to say that I am an Atheist, because, when I say that I cannot prove that there is not a God, I ought to add equally that I cannot prove that there are not the Homeric gods.

Every man would like to be God, if it were possible; some few find it difficult to admit the impossibility.

Probably in time physiologists will be able to make nerves connecting the bodies of different people; this will have the advantage that we shall be able to feel another man's tooth aching.

Cock-sure certainty is the source of much that is worst in our present world, and it is something of which the contemplation of history ought to cure us, not only or chiefly because there were wise men in the past, but because so much that was thought wisdom turned out to be folly - which suggests that much of our own supposed wisdom is no better. I do not mean to maintain that we should lapse into a lazy scepticism. We should hold our beliefs, and hold them strongly. Nothing great is achieved without passion, but underneath the passion there should always be that large impersonal survey which sets limits to actions that our passions inspire.

The love of power is a part of human nature, but power-philosophies are, in a certain precise sense, insane. The existence of the external world, both that of matter and of other human beings, is a datum, which may be humiliating to a certain kind of pride, but can only be denied by a madman. Men who allow their love of power to give them a distorted view of the world are to be found in every asylum: one man will think he is Governor of the Bank of England, another will think he is the King, and yet another will think he is God. Highly similar delusions, if expressed by educated men in obscure language, lead to professorships in philosophy; and if expressed by emotional men in eloquent language, lead to dictatorships. Certified lunatics are shut up because of the proneness to violence when their pretensions are questioned; the uncertified variety are given control of powerful armies, and can inflict death and disaster upon all sane men within their reach.

A stupid man's report of what a clever man says is never accurate, because he unconsciously translates what he hears into something that he can understand.

For my part, while I am as convinced a Socialist as the most ardent Marxian, I do not regard Socialism as a gospel of proletarian revenge, nor even, primarily, as a means of securing economic justice. I regard it primarily as an adjustment to machine production demanded by considerations of common sense, and calculated to increase the happiness, not only of proletarians, but of all except a tiny minority of the human race.

Men tend to have the beliefs that suit their passions. Cruel men believe in a cruel God, and use their belief to excuse their cruelty. Only kindly men believe in a kindly God, and they would be kindly in any case.

People will tell us that without the consolations of religion they would be intolerably unhappy. So far as this is true, it is a coward's argument. Nobody but a coward would consciously choose to live in a fool's paradise. When a man suspects his wife of infidelity, he is not thought the better of for shutting his eyes to the evidence. And I cannot see why ignoring evidence should be contemptible in one case and admirable in the other.

Belief in eternal hell fire was an essential item of Christian belief until pretty recent times. In this country, as you know, it ceased to be an essential item because of a decision of the Privy Council, and from that decision the Archbishop of Canterbury and the Archbishop of York dissented; but in this country our religion is settled by Act of Parliament, and therefore the Privy Council was able to override Their Graces and hell was no longer necessary to a Christian. Consequently I shall not insist that a Christian must believe in hell. What is a Christian?

Marriage is for women the commonest mode of livelihood, and the total amount of undesired sex endured by women is probably greater in marriage than in prostitution.

I regard [religion] as a disease born of fear and as a source of untold misery to the human race.

Man is essentially a dreamer, wakened sometimes for a moment by some peculiarly obtrusive element in the outer world, but lapsing again quickly into the happy somnolence of imagination. Freud has shown how largely our dreams at night are the pictured fulfilment of our wishes; he has, with an equal measure of truth, said the same of day-dreams; and he might have included the day-dreams which we call beliefs.

You will have seen that my brother died suddenly in Marseilles. I inherit from him a title, but not a penny of money, as he was bankrupt. A title is a great nuisance to me, and I am at a loss what to do, but at any rate I do not wish it employed in connection with any of my literary work. There is, so far as I know, only one method of getting rid of it, which is to be attainted of high treason, and this would involve my head being cut off on Tower Hill. This method seems to me perhaps somewhat extreme...

We cannot suppose that an individual's thinking survives bodily death, since that destroys the organization of the brain and dissipates the energy which utilized the brain tracks. God and immortality, the central dogma of the Christian religion, find no support in science. But we in the West have come to think of them as the irreducible minimum of theology. No doubt people will continue to entertain these beliefs, because they are pleasant, just as it is pleasant to think ourselves virtuous and our enemies wicked. But for my part I cannot see any grounds for either. I do not pretend to be able to prove that there is no God. I equally cannot prove Satan is a fiction. The Christian God may exist, so might the Gods of Olympus, Ancient Egypt or Babylon; but no one of these hypotheses is more probable than any other. They lie outside the region of provable knowledge and there is no reason to consider any of them.

Americans need rest, but do not know it. I believe this to be a large part of the explanation of the crime wave in the United States.

Drunkenness is temporary suicide.

I do not think that the real reason why people accept religion has anything to do with argumentation. They accept religion on emotional grounds. One is often told that it is a very wrong thing to attack religion, because religion makes men virtuous. So I am told; I have not noticed it.

The most essential characteristic of scientific technique is that it proceeds from experiment, not from tradition. The experimental habit of mind is a difficult one for most people to maintain; indeed, the science of one generation has already become the tradition of the next...

I found one day in school a boy of medium size ill-treating a smaller boy. I expostulated, but he replied: "The bigs hit me, so I hit the babies; that's fair." In these words he epitomized the history of the human race.

Next to enjoying ourselves, the next greatest pleasure consists in preventing others from enjoying themselves, or, more generally, in the acquisition of power.

At the present stage in the development of the art of war, there is only way of coping with them, and that is to keep out of war. In all the densely populated countries of Western Europe, it seems almost certain that, within a few days of the outbreak of war, panic will seize the surviving inhabitants of the capitals and the industrial areas, leading to anarchy, starvation, and paralysis of all warlike effort. The only sensible course, therefore, is to prevent war if possible, and to remain neutral if war occurs.

If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument. It is exactly of the same nature as the Hindu's view, that the world rested upon an elephant and the elephant rested upon a tortoise; and when they said, "How about the tortoise?" the Indian said, "Suppose we change the subject." The argument is really no better than that.

To fear love is to fear life, and those who fear life are already three parts dead.

It is amusing to hear the modern Christian telling you how mild and rationalistic Christianity really is and ignoring the fact that all its mildness and rationalism is due to the teaching of men who in their own day were persecuted by all orthodox Christians.

Every man, wherever he goes, is encompassed by a cloud of comforting convictions, which move with him like flies on a summer day.

I am sorry to say that at the moment I am so busy as to be convinced that life has no meaning whatever... I do not see that we can judge what would be the result of the discovery of truth, since none has hitherto been discovered.

The philosophy of nature must not be unduly terrestrial; for it, the earth is merely one of the smaller planets of one of the smaller stars of the Milky Way. It would be ridiculous to warp the philosophy of nature in order to bring out results that are pleasing to the tiny parasites of this insignificant planet. Vitalism as a philosophy, and evolutionism, show, in this respect, a lack of sense of proportion and logical relevance. They regard the facts of life, which are personally interesting to us, as having a cosmic significance, not a significance confined to the earth's surface. Optimism and pessimism, as cosmic philosophies, show the same naive humanism; the great world, so far as we know it from the philosophy of nature, is neither good nor bad, and is not concerned to make us happy or unhappy. All such philosophies spring from self-importance and are best corrected by a little astronomy.

Advocates of capitalism are very apt to appeal to the sacred principles of liberty, which are embodied in one maxim: The fortunate must not be restrained in the exercise of tyranny over the unfortunate.

To be without some of the things you want is an indispensable part of happiness.

You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or even mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world. I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world.

A world without delight and without affection is a world destitute of value.

Belief in God and a future life makes it possible to go through life with less of stoic courage than is needed by skeptics. A great many young people lose faith in these dogmas at an age at which despair is easy, and thus have to face a much more intense unhappiness than that which falls to the lot of those who have never had a religious upbringing. Christianity offers reasons for not fearing death or the universe, and in so doing it fails to teach adequately the virtue of courage. The craving for religious faith being largely an outcome of fear, the advocates of faith tend to think that certain kinds of fear are not to be deprecated. In this, to my mind, they are gravely mistaken. To allow oneself to entertain pleasant beliefs as a means of avoiding fear is not to live in the best way. In so far as religion makes its appeal to fear, it is lowering to human dignity.

William James used to preach the "will-to-believe." For my part, I should wish to preach the "will-to-doubt." None of our beliefs are quite true; all at least have a penumbra of vagueness and error. What is wanted is not the will to believe, but the will to find out, which is the exact opposite.

It is the duty of all who care for their country or for civilisation to point out that we cannot further any of our ideals by participation in the next war, and that we ought therefore to resist all measures based upon the assumption that we shall take part in it. In the late war it was arguable that victory, being possible, might do some good. With the modern technique of gas attack, no belligerent can hope for victory. Absolute pacifism, therefore, in every country, in which it is politically possible, is the only sane policy both for Governments and individuals.

...You could take up the line that some of the gnostics took up - a line which I often thought was a very plausible one - that as a matter of fact this world that we know was made by the devil at a moment when God was not looking. There is a good deal to be said for that, and I am not concerned to refute it.

The place of the father in the modern suburban family is a very small one - particularly if he plays golf, which he usually does.

If, when a man writes a poem or commits a murder, the bodily movements involved in his act result solely from physical causes, it would seem absurd to put up a statue to him in the one case and to hang him in the other.

Machines are worshipped because they are beautiful and valued because they confer power; they are hated because they are hideous and loathed because they impose slavery.

A religious creed differs from a scientific theory in claiming to embody eternal and absolutely certain truth, whereas science is always tentative, expecting that modification in its present theories will sooner or later be found necessary, and aware that its method is one which is logically incapable of arriving at a complete and final demonstration.
