History is invaluable in increasing our knowledge of human nature because it shows how people may be expected to behave in new situations. Many prominent men and women are completely ordinary in character and only exceptional in their circumstances.

Not to be absolutely certain is, I think, one of the essential things in rationality.

“Am I An Atheist Or An Agnostic?” (1947)

Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones.
The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion.
Man is a rational animal — so at least I have been told. Throughout a long life, I have looked diligently for evidence in favor of this statement, but so far I have not had the good fortune to come across it.
To avoid the various foolish opinions to which mankind are prone, no superhuman genius is required. A few simple rules will keep you, not from all error, but from silly error. If the matter is one that can be settled by observation, make the observation yourself. Aristotle could have avoided the mistake of thinking that women have fewer teeth than men, by the simple device of asking Mrs. Aristotle to keep her mouth open while he counted. He did not do so because he thought he knew. Thinking that you know when in fact you don’t is a fatal mistake, to which we are all prone. I believe myself that hedgehogs eat black beetles, because I have been told that they do; but if I were writing a book on the habits of hedgehogs, I should not commit myself until I had seen one enjoying this unappetizing diet.
A life which goes excessively against natural impulse is […] likely to involve effects of strain that may be quite as bad as indulgence in forbidden impulses would have been. People who live a life which is unnatural beyond a point are likely to be filled with envy, malice and uncharitableness.
There are large parts of the Christian ethic which are universally admitted to be too good for this wicked world. We have in fact, two kinds of morality, side by side: one that we preach, but do not practice, and another that we practice, but seldom preach.
Why do people read? The answer, as regards the great majority, is: “They don’t.”

It is clear that thought is not free if the profession of certain opinions makes it impossible to earn a living.
Bertrand Russell (1872-1970) English mathematician and philosopher
“Free Thought and Official Propaganda,” lecture, South Place Institute, London (24 Mar 1922)
It is clear that the most elementary condition, if thought is to be free, is the absence of legal penalties for the expression of opinions. No great country has yet reached to this level, although most of them think they have. The opinions which are still persecuted strike the majority as so monstrous and immoral that the general principle of toleration can not be held to apply to them. But this is exactly the same view as that which made possible the tortures of the Inquisition. There was a time when Protestantism seemed as wicked as Bolshevism seems now.
The essence of good manners consists in making it clear that one has no wish to hurt. When it is clearly necessary to hurt, it must be done in such a way as to make it evident that the necessity is felt to be regrettable.

I have often wondered what turkeys would think of Christmas if they were capable of thought. I am afraid they would hardly regard it as a season of peace and goodwill.

“If animals could talk,” New York American (14 Sep 1932)
(Source)
There is no impersonal reason for regarding the interests of human beings as more important than those of animals. We can destroy animals more easily than they can destroy us; that is the only solid basis of our claim to superiority. We value art and science and literature, because these are things in which we excel. But whales might value spouting, and donkeys might maintain that a good bray is more exquisite than the music of Bach. We cannot prove them wrong except by the exercise of arbitrary power. All ethical systems, in the last analysis, depend upon weapons of war.

Many orthodox people speak as though it were the business of sceptics to disprove received dogmas rather than of dogmatists to prove them. This is, of course, a mistake. If I were to suggest that between the Earth and Mars there is a china teapot revolving about the sun in an elliptical orbit, nobody would be able to disprove my assertion provided I were careful to add that the teapot is too small to be revealed even by our most powerful telescopes. But if I were to go on to say that, since my assertion cannot be disproved, it is intolerable presumption on the part of human reason to doubt it, I should rightly be thought to be talking nonsense. If, however, the existence of such a teapot were affirmed in ancient books, taught as the sacred truth every Sunday, and instilled into the minds of children at school, hesitation to believe in its existence would become a mark of eccentricity and entitle the doubter to the attentions of the psychiatrist in an enlightened age or of the Inquisitor in an earlier time.

Manners consist in pretending that we think as well of others as of ourselves. Manners are necessary because, as a rule, there is a pretence; when our good opinion of others is genuine, manners look after themselves. Perhaps instead of teaching manners, parents should teach the statistical probability that the person you are speaking to is just as good as you are. It is difficult to believe this; very few of us do, in our instincts, believe it. One’s own ego seems so incomparably more sensitive, more perceptive, wiser and more profound than other people’s. Yet there must be very few of whom this is true, and it is not likely that oneself is one of those few. There is nothing like viewing oneself statistically as a means both to good manners and to good morals.

A physician would not cure his patients more effectually if he were angry with them for being ill, and the criminal law is not more effective when it is inspired by anger against the criminal. The criminal presents a problem, psychological, educational, sociological, and economic; this difficult problem is not best handled in a state of blind rage. All arguments for corporal punishment spring from anger, not from scientific understanding. As men become more scientific, such barbaric practices will be no longer tolerated.

Neither acquiescence in skepticism nor acquiescence in dogma is what education should produce. What it should produce is a belief that knowledge is attainable in a measure, though with difficulty; that much of what passes for knowledge at any given time is likely to be more or less mistaken, but that the mistakes can be rectified by care and industry.
Knowledge, like other good things, is difficult, but not impossible; the dogmatist forgets the difficulty, the skeptic denies the possibility. Both are mistaken, and their errors, when widespread, produce social disaster.
Expect of the young the very best of which they are capable, and you will get it. Expect less, and it is only too likely that you will get no more than you expect.

All the higher animals have methods of expressing pleasure, but human beings alone express pleasure when they do not feel it. This is called politeness and is reckoned among the virtues.

One of the most disconcerting things about infants is that they only smile when they are pleased. They stare at visitors with round grave eyes, and when the visitors try to amuse them, they display astonishment at the foolish antics of adults. But as soon as possible, their parents teach them to seem pleased by the company of people to whom they are utterly indifferent.

The essence of the Liberal outlook lies not in what opinions are held, but in how they are held: instead of being held dogmatically, they are held tentatively, and with a consciousness that new evidence may at any moment lead to their abandonment.

Dogmatism and skepticism are both, in a sense, absolute philosophies; one is certain of knowing, the other of not knowing. What philosophy should dissipate is certainty, whether of knowledge or ignorance.
The widespread interest in gossip is inspired, not by a love of knowledge, but by malice: no one gossips about other people’s secret virtues, but only about their secret vices. Accordingly most gossip is untrue, but care is taken not to verify it. Our neighbour’s sins, like the consolations of religion, are so agreeable that we do not stop to scrutinize the evidence closely.

One who believes as I do, that free intellect is the chief engine of human progress, cannot but be fundamentally opposed to Bolshevism as much as to the Church of Rome. The hopes which inspire communism are, in the main, as admirable as those instilled by the Sermon on the Mount, but they are held as fanatically and are as likely to do as much harm.

Attributed to many modern authors, including John Lennon,  T. S. Elliot, Lawrence J. Peter, and  Soren Kierkegaard. Most often attributed to Russell. it is actually a comment/interpretation by Peter in Peter's Quotations about a different Russell quote ("The thing that I should wish to obtain from money would be leisure with security"). In turn, the words were not original with Peter. More information.
I was told that the Chinese said they would bury me by the Western Lake and build a shrine to my memory. I have some slight regret that this did not happen as I might have become a god, which would have been very chic for an atheist.
One should respect public opinion in so far as is necessary to avoid starvation and to keep out of prison, but anything that goes beyond this is voluntary submission to an unnecessary tyranny.

I do not believe that I am now dreaming, but I cannot prove that I am not. I am, however, quite certain that I am having certain experiences, whether they be those of a dream or those of waking life.
It seems to me that science has a much greater likelihood of being true in the main than any philosophy hitherto advanced (I do not, of course, except my own). In science there are many matters about which people are agreed; in philosophy there are none. Therefore, although each proposition in a science may be false, and it is practically certain that there are some that are false, yet we shall be wise to build our philosophy upon science, because the risk of error in philosophy is pretty sure to be greater than in science. If we could hope for certainty in philosophy, the matter would be otherwise, but so far as I can see such a hope would be chimerical.
Morality in sexual situations, when it is free from superstition, consists essentially of respect for the other person, and unwillingness to use that person solely as a means of personal gratification, without regard to his or her desires.
The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd; indeed in view of the silliness of the majority of mankind, a widespread belief is more likely to be foolish than sensible.
Nine-tenths of the appeal of pornography is due to the indecent feelings concerning sex which moralists inculcate in the young; the other tenth is physiological, and will occur in one way or another whatever the state of the law may be. On these grounds, although I fear that few will agree with me, I am firmly persuaded that there ought to be no law whatsoever on the subject of obscene publications.
Just as we teach children to avoid being destroyed by motor cars if they can, so we should teach them to avoid being destroyed by cruel fanatics, and to this end we should seek to produce independence of mind, somewhat sceptical and wholly scientific, and to preserve, as far as possible, the instinctive joy of life that is natural to healthy children. This is the task of a liberal education: to give a sense of the value of things other than domination, to help create wise citizens of a free community, and through the combination of citizenship with liberty in individual creativeness to enable men to give to human life that splendour which some few have shown that it can achieve.
Something of the hermit’s temper is an essential element in many forms of excellence, since it enables a man to resist the lure of popularity, to pursue important work in spite of general indifference or hostility, and arrive at opinions which are opposed to prevalent errors.
If the object were to make pupils think, rather than to make them accept certain conclusions, education would be conducted quite differently; there would be less … instruction and more discussion.
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 sciences have developed in an order the reverse of what might have been expected. What was most remote from ourselves was first brought under the domain of law, and then, gradually, what was nearer: first the heavens, next the earth, then animal and vegetable life, then the human body, and last of all (as yet very imperfectly) the human mind.
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.
It is natural to most men to suppose that they have enemies and to find a certain fulfillment of their nature when they embark upon a contest. What a man believes upon grossly insufficient evidence is an index to his desires — desires of which he himself is often unconscious. If a man is offered a fact which goes against his instincts, he will scrutinize it closely, and unless the evidence is overwhelming, he will refuse to believe it. If, on the other hand, he is offered something which affords a reason for acting in accordance with his instincts, he will accept it even on the slenderest evidence. The origin of myths is explained in this way, and much of what is currently believed in international affairs is no better than myth.

The opinions that are held with passion are always those for which no good ground exists; indeed the passion is the measure of the holder’s lack of rational conviction. Opinions in politics and religion are almost always held passionately.
Education should have two objects: first, to give definite knowledge, reading and writing, language and mathematics, and so on; secondly, to create those mental habits which will enable people to acquire knowledge and form sound judgments for themselves.
Next to enjoying ourselves, the next greatest pleasure consists in preventing others from enjoying themselves, or, more generally, in the acquisition of power. Consequently those who live under the dominion of Puritanism become exceedingly desirous of power.
I was much cheered upon my arrival (in prison), by the warden at the gate, who had to take particulars about me. He asked my religion, and I replied, ‘Agnostic.’ He asked how to spell it, and remarked with a sigh, “Well, there are many religions, but I suppose they all worship the same God.”
