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.

The old often envy the young; when they do, they are apt to treat them cruelly.

Children must be under authority, and are themselves aware that they must be, although they like to play a game of rebellion at times. The case of children is unique in the fact that those who have authority over them are sometimes fond of them. Where this is the case, the children do not resent the authority in general, even when they resist it on particular occasions. Education authorities, as opposed to teachers, have not this merit, and do in fact sacrifice the children to what they consider the good of the State by teaching them "patriotism," i.e., a willingness to kill and be killed for trivial reasons.

There are two motives for reading a book: one, that you enjoy it; the other, that you can boast about it.

The church is in its major part an opponent still of progress and improvement in all the ways that diminish suffering in the world, because it has chosen to label as morality a certain narrow set of rules of conduct which have nothing to do with human happiness; and when you say that this or that ought to be done because it would make for human happiness, they think that has nothing to do with the matter at all. "What has human happiness to do with morals? The object of morals is not to make people happy."

All exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man.

Owing to the identification of religion with virtue, together with the fact that the most religious men are not the most intelligent, a religious education gives courage to the stupid to resist the authority of educated men, as has happened, for example, where the teaching of evolution has been made illegal. So far as I can remember, there is not one word in the Gospels in praise of intelligence; and in this respect ministers of religion follow gospel authority more closely than in some others.

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.

When I say that children should be told about sex, I do not mean that they should be told only the bare physiological facts; they should be told whatever they wish to know. There should be no attempt to represent adults as more virtuous than they are, or sex as occurring only in marriage. There is no excuse for deceiving children. And when, as must happen in conventional families, they find that their parents have lied, they lose confidence in them, and feel justified in lying to them.

In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying.

Apart from autograph hunters, I get... many letters from Hindus, beseeching me to adopt some form of mysticism, from young Americans, asking me where I think the line should be drawn in petting, and from Poles, urging me to admit that while all other nationalism may be bad that of Poland is wholly noble. I get letters from engineers who cannot understand Einstein, and from parsons who think that I cannot understand Genesis, from husbands whose wives have deserted them - not (they say) that that would matter, but the wives have taken the furniture with them, and what in these circumstances should an enlightened male do? ...I get letters (concerning whose genuineness I am suspicious) trying to get me to advocate abortion, and I get letters from young mothers asking my opinion of bottle-feeding.

When a man acts in ways that annoy us we wish to think him wicked, and we refuse to face the fact that his annoying behaviour is a result of antecedent causes which, if you follow them long enough, will take you beyond the moment of his birth and therefore to events for which he cannot be held responsible by any stretch of imagination.

A European who goes to New York and Chicago sees the future... when he goes to Asia he sees the past.

While it is true that science cannot decide questions of value, that is because they cannot be intellectually decided at all, and lie outside the realm of truth and falsehood. Whatever knowledge is attainable, must be attained by scientific methods; and what science cannot discover, mankind cannot know.

I am as firmly convinced that religions do harm as I am that they are untrue.

The fundamental defect of fathers, in our competitive society, is that they want their children to be a credit to them.

One of the symptoms of approaching nervous breakdown is the belief that one's work is terribly important, and that to take a holiday would bring all kinds of disaster. If I were a medical man, I should prescribe a holiday to any patient who considered his work important.

The whole conception of God is a conception derived from the ancient Oriental despotisms. It is a conception quite unworthy of free men. When you hear people in church debasing themselves and saying that they are miserable sinners, and all the rest of it, it seems contemptible and not worthy of self-respecting human beings. We ought to stand up and look the world frankly in the face. We ought to make the best we can of the world, and if it is not so good as we wish, after all it will still be better than what these others have made of it in all these ages. A good world needs knowledge, kindliness, and courage; it does not need a regretful hankering after the past, or a fettering of the free intelligence by the words uttered long ago by ignorant men.

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.

I am sure that university life would be better, both intellectually and morally, if most university students had temporary childless marriages. This would afford a solution to the sexual urge neither restless nor surreptitious, neither mercenary nor casual, and of such a nature that it need not take up time which ought to be given to work.

The State is a collection of officials, different for difference purposes, drawing comfortable incomes so long as the status quo is preserved. The only alteration they are likely to desire in the status quo is an increase of bureaucracy and the power of bureaucrats.

It is only when we think abstractly that we have such a high opinion of man. Of men in the concrete, most of us think the vast majority very bad. Civilized states spend more than half their revenue on killing each other's citizens. Consider the long history of the activities inspired by moral fervour: human sacrifices, persecutions of heretics, witch-hunts, pogroms leading up to wholesale extermination by poison gases ... Are these abominations, and the ethical doctrines by which they are prompted, really evidence of an intelligent Creator? And can we really wish that the men who practised them should live for ever? The world in which we live can be understood as a result of muddle and accident; but if it is the outcome of a deliberate purpose, the purpose must have been that of a fiend. For my part, I find accident a less painful and more plausible hypothesis.

I have no doubt that the present Prime Minister, for instance, is a most sincere Christian, but I should not advise any of you to go and smite him on one cheek. I think you might find that he thought this text was intended in a figurative sense.

It is likely that America will be more important during the next century or two, but after that it may well be the turn of China.

No man treats a motorcar as foolishly as he treats another human being. When the car will not go, he does not attribute its annoying behaviour to sin; he does not say, "You are a wicked motorcar, and I shall not give you any more petrol until you go." He attempts to find out what is wrong and to set it right. An analogous way of treating human beings is, however, considered to be contrary to the truths of our holy religion.

We have, in fact, two kinds of morality side by side; one which we preach but do not practise, and another which we practise but seldom preach.

Why in any case, this glorification of man? How about lions and tigers? They destroy fewer animals or human lives than we do, and they are much more beautiful than we are. How about ants? They manage the Corporate State much better than any Fascist. Would not a world of nightingales and larks and deer be better than our human world of cruelty and injustice and war? The believers in Cosmic Purpose make much of our supposed intelligence, but their writings make one doubt it. If I were granted omnipotence, and millions of years to experiment in, I should not think Man much to boast of as the final result of all my efforts.

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.

If human nature were unchangeable, as ignorant people still suppose it to be, the situation would indeed be hopeless.

The secret of happiness is this: let your interests be as wide as possible, and let your reactions to the things and persons that interest you be as far as possible friendly rather than hostile.

I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true.

I think people who are unhappy are always proud of being so, and therefore do not like to be told that there is nothing grand about their unhappiness. A man who is melancholy because lack of exercise has upset his liver always believes that it is the loss of God, or the menace of Bolshevism, or some such dignified cause that makes him sad. When you tell people that happiness is a simple matter, they get annoyed with you.

There are those who blame the Press, but in this I think they are mistaken. The Press is such as the public demands, and the public demands bad newspapers because it has been badly educated.

We are faced with the paradoxical fact that education has become one of the chief obstacles to intelligence and freedom of thought.

Religions, which condemn the pleasures of sense, drive men to seek the pleasures of power. Throughout history power has been the vice of the ascetic.

I knew a parson who frightened his congregation terribly by telling them that the second coming was very imminent indeed, but they were much consoled when they found that he was planting trees in his garden.

I quite understand the principle of confining employment as far as possible to the British without regard for efficiency. I think, however, that the Ministry is not applying the principle sufficiently widely. I know many Englishmen who have married foreigners, and many English potential wives who are out of a job. Would not a year be long enough to train an English wife to replace the existing foreign one in such cases?

Now, what is 'unrighteousness' in practice? It is in practice behavior of a kind disliked by the herd. By calling it unrighteousness, and by arranging an elaborate system of ethics around this conception, the herd justifies itself in wreaking punishment upon the objects of its own dislike, while at the same time, since the herd is righteous by definition, it enhances its own self-esteem at the very moment when it lets loose its impulse to cruelty. This is the psychology of lynching, and of the other ways in which criminals are punished. The essence of the conception of righteousness, therefore, is to afford an outlet for sadism by cloaking cruelty as justice.

The people who are regarded as moral luminaries are those who forego ordinary pleasures themselves and find compensation in interfering with the pleasures of others.
