Bertrand Russell Quotes (562 quotes, page 9)

“So much of modern mathematical work is obviously on the border-line of logic, so much of modern logic is symbolic and formal, that the very close relationship of logic and mathematics has become obvious to every instructed student. The proof of their identity is, of course, a matter of detail: starting with premisses which would be universally admitted to belong to logic, and arriving by deduction at results which as obviously belong to mathematics, we find that there is no point at which a sharp line can be drawn, with logic to the left and mathematics to the right. If there are still those who do not admit the identity of logic and mathematics, we may challenge them to indicate at what point, in the successive definitions and deductions of Principia Mathematica, they consider that logic ends and mathematics begins. It will then be obvious that any answer must be quite arbitrary.”

“My own opinion—which I may as well indicate at the outset—is that pure Anarchism, though it should be the ultimate ideal, to which society should continually approximate, is for the present impossible, and would not survive more than a year or two at most if it were adopted. On the other hand, both Marxian Socialism and Syndicalism, in spite of many drawbacks, seem to me calculated to give rise to a happier and better world than that in which we live. I do not, however, regard either of them as the best practicable system. Marxian Socialism, I fear, would give far too much power to the State, while Syndicalism, which aims at abolishing the State, would, I believe, find itself forced to reconstruct a central authority in order to put an end to the rivalries of different groups of producers. The best practicable system, to my mind, is that of Guild Socialism, which concedes what is valid both in the claims of the State Socialists and in the Syndicalist fear of the State, by adopting a system of federalism among trades for reasons similar to those which are recommending federalism among nations.”

“I wanted certainty in the kind of way in which people want religious faith. I thought that certainty is more likely to be found in mathematics than elsewhere. But I discovered that many mathematical demonstrations, which my teachers expected me to accept, were full of fallacies, and that, if certainty were indeed discoverable in mathematics, it would be in a new field of mathematics, with more solid foundations than those that had hitherto been thought secure. But as the work proceeded, I was continually reminded of the fable about the elephant and the tortoise. having constructed an elephant upon which the mathematical world could rest, I found the elephant tottering, and proceeded to construct a tortoise to keep the elephant from falling. But the tortoise was no more secure than the elephant, and after some twenty years of very arduous toil, I came to the conclusion that there was nothing more that I could do in the way of making mathematical knowledge indubitable.”

“What a queer work the Bible is.
… Some texts are very funny. Deut. XXIV, 5: "When a man hath taken a new wife, he shall not go out to war, neither shall he be charged with any business: but he shall be free at home one year, and shall cheer up his wife which he hath taken." I should never have guessed "cheer up" was a Biblical expression. Here is another really inspiring text: "Cursed be he that lieth with his mother-in-law. And all the people shall say, Amen." St Paul on marriage: "I say therefore to the unmarried and widows, It is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn." This has remained the doctrine of the Church to this day. It is clear that the Divine purpose in the text "it is better to marry than to burn" is to make us all feel how very dreadful the torments of Hell must be.”

“We may define "faith" as a firm belief in something for which there is no evidence. Where there is evidence, no one speaks of "faith". We do not speak of faith that two and two are four or that the earth is round. We only speak of faith when we wish to substitute emotion for evidence. The substitution of emotion for evidence is apt to lead to strife, since different groups substitute different emotions.”

“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.”

“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 great deal of work is sedentary, and most manual work exercises only a few specialized muscles. When crowds assemble in Trafalgar Square to cheer to the echo an announcement that the government has decided to have them killed, they would not do so if they had all walked twenty-five miles that day. This cure for bellicosity is, however, impracticable, and if the human race is to survive – a thing which is, perhaps, undesirable – other means must be found for securing an innocent outlet for the unused physical energy that produces love of excitement. This is a matter which has been too little considered, both by moralists and by social reformers. The social reformers are of the opinion that they have more serious things to consider. The moralists, on the other hand, are immensely impressed with the seriousness of all the permitted outlets of the love of excitement; the seriousness, however, in their minds, is that of Sin. Dance halls, cinemas, this age of jazz, are all, if we may believe our ears, gateways to Hell, and we should be better employed sitting at home contemplating our sins. I find myself unable to be in entire agreement with the grave men who utter these warnings. The devil has many forms, some designed to deceive the young, some designed to deceive the old and serious. If it is the devil that tempts the young to enjoy themselves, is it not, perhaps, the same personage that persuades the old to condemn their enjoyment? And is not condemnation perhaps merely a form of excitement appropriate to old age? And is it not, perhaps, a drug which – like opium – has to be taken in continually stronger doses to produce the desired effect? Is it not to be feared that, beginning with the wickedness of the cinema, we should be led step by step to condemn the opposite political party, dagoes, wops, Asiatics, and, in short, everybody except the fellow members of our club? And it is from just such condemnations, when widespread, that wars proceed. I have never heard of a war that proceeded from dance halls.”

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.”

“The best authorities are unanimous in saying that a war with H-bombs might possibly put an end to the human race. It is feared that if many H-bombs are used there will be universal death, sudden only for a minority, but for the majority a slow torture of disease and disintegration.
Many warnings have been uttered by eminent men of science and by authorities in military strategy. None of them will say that the worst results are certain. What they do say is that these results are possible, and no one can be sure that they will not be realized. We have not yet found that the views of experts on this question depend in any degree upon their politics or prejudices. They depend only, so far as our researches have revealed, upon the extent of the particular expert's knowledge. We have found that the men who know most are the most gloomy.”

“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.

“Soon after my arrival in Moscow I had an hour's conversation with Lenin in English, which he speaks fairly well… I have never met a personage so destitute of self-importance. He looks at his visitors very closely, and screws up one eye, which seems to increase alarmingly the penetrating power of the other. He laughs a great deal; at first his laugh seems merely friendly and jolly, but gradually I came to feel it rather grim. He is dictatorial, calm, incapable of fear, extraordinarily devoid of self-seeking, an embodied theory. The materialist conception of history, one feels, is his life-blood. He resembles a professor in his desire to have the theory understood and in his fury with those who misunderstand or disagree, as also in his love of expounding, I got the impression that he despises a great many people and is an intellectual aristocrat.
…When I suggested that whatever is possible in England can be achieved without bloodshed, he waved aside the suggestion as fantastic… He described the division between rich and poor peasants, and the Government propaganda among the latter against the former, leading to acts of violence which he seemed to find amusing.”

“[T]he philosophy of Plotinus has the defect of encouraging men to look within rather than to look without: when we look within we see nous, which is divine, while when we look without we see the imperfections of the sensible world. This kind of subjectivity was a gradual growth; it is to be found in the doctrines of Protagoras, Socrates, and Plato, as well as in the Stoics and Epicureans. But at first it was only doctrinal, not temperamental; for a long time it failed to kill scientific curiosity. […] Plotinus is both an end and a beginning—an end as regards the Greeks, a beginning as regards Christendom.”

“Suppose that, at a given moment, a certain number of people are engaged in the manufacture of pins. They make as many pins as the world needs, working (say) eight hours a day. Someone makes an invention by which the same number of men can make twice as many pins: pins are already so cheap that hardly any more will be bought at a lower price. In a sensible world, everybody concerned in the manufacturing of pins would take to working four hours instead of eight, and everything else would go on as before. But in the actual world this would be thought demoralizing. The men still work eight hours, there are too many pins, some employers go bankrupt, and half the men previously concerned in making pins are thrown out of work. There is, in the end, just as much leisure as on the other plan, but half the men are totally idle while half are still overworked. In this way, it is insured that the unavoidable leisure shall cause misery all round instead of being a universal source of happiness. Can anything more insane be imagined?”

“When, in youth, I learned what was called "philosophy" … no one ever mentioned to me the question of "meaning." Later, I became acquainted with Lady Welby's work on the subject, but failed to take it seriously. I imagined that logic could be pursued by taking it for granted that symbols were always, so to speak, transparent, and in no way distorted the objects they were supposed to "mean." Purely logical problems have gradually led me further and further from this point of view. Beginning with the question whether the class of all those classes which are not members of themselves is, or is not, a member of itself; continuing with the problem whether the man who says "I am lying" is lying or speaking the truth; passing through the riddle "is the present King of France bald or not bald, or is the law of excluded middle false?" I have now come to believe that the order of words in time or space is an ineradicable part of much of their significance – in fact, that the reason they can express space-time occurrences is that they are space-time occurrences, so that a logic independent of the accidental nature of spacetime becomes an idle dream. These conclusions are unpleasant to my vanity, but pleasant to my love of philosophical activity: until vitality fails, there is no reason to be wedded to one's past theories.”

“The number of syllables in the English names of finite integers tends to increase as the integers grow larger, and must gradually increase indefinitely, since only a finite number of names can be made with a given finite number of syllables. Hence the names of some integers must consist of at least nineteen syllables, and among these there must be a least. Hence "the least integer not nameable in fewer than nineteen syllables" must denote a definite integer; in fact, it denotes 111, 777. But "the least integer not nameable in fewer than nineteen syllables" is itself a name consisting of eighteen syllables; hence the least integer not nameable in fewer than nineteen syllables can be named in eighteen syllables, which is a contradiction. This contradiction was suggested to us by Mr. G. G. Berry of the Bodleian Library.”
