"Inquiry into the evidence of a doctrine is not to be made once for all, and then taken as finally settled. It is never lawful to stifle a doubt; for either it can be honestly answered by means of the inquiry already made, or else it proves that the inquiry was not complete. "But," says one, "I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments." Then he should have no time to believe."
"We may believe what goes beyond our experience, only when it is inferred from that experience by the assumption that what we do not know is like what we know. We may believe the statement of another person, when there is reasonable ground for supposing that he knows the matter of which he speaks, and that he is speaking the truth so far as he knows it.It is wrong in all cases to believe on insufficient evidence; and where it is presumption to doubt and to investigate, there it is worse than presumption to believe."
"To sum up: it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence. If a man, holding a belief which he was taught in childhood or persuaded of afterwards, keeps down and pushes away any doubts which arise about it in his mind, purposely avoids the reading of books and the company of men that call into question or discuss it, and regards as impious those questions which cannot easily be asked without disturbing it--the life of that man is one long sin against mankind."
"It is hardly in human nature that a man should quite accurately gauge the limits of his own insight; but it is the duty of those who profit by his work to consider carefully where he may have been carried beyond it. If we must needs embalm his possible errors along with his solid achievements, and use his authority as an excuse for believing what he cannot have known, we make of his goodness an occasion to sin."
"Our lives are guided by that general conception of the course of things which has been created by society for social purposes. Our words, our phrases, our forms and processes and modes of thought, are common property, fashioned and perfected from age to age; an heirloom which every succeeding generation inherits as a precious deposit and a sacred trust to be handled on to the next one, not unchanged but enlarged and purified, with some clear marks of its proper handiwork. Into this, for good or ill, is woven every belief of every man who has speech of his fellows. An awful privilege, and an awful responsibility, that we should help to create the world in which posterity will live."
"Belief, that sacred faculty which prompts the decisions of our will, and knits into harmonious working all the compacted energies of our being, is ours not for ourselves but for humanity. It is rightly used on truths which have been established by long experience and waiting toil, and which have stood in the fierce light of free and fearless questioning. Then it helps to bind men together, and to strengthen and direct their common action. It is desecrated when given to unproved and unquestioned statements, for the solace and private pleasure of the believer; to add a tinsel splendour to the plain straight road of our life and display a bright mirage beyond it; or even to drown the common sorrows of our kind by a self-deception which allows them not only to cast down, but also to degrade us. Whoso would deserve well of his fellows in this matter will guard the purity of his beliefs with a very fanaticism of jealous care, lest at any time it should rest on an unworthy object, and catch a stain which can never be wiped away. It is not only the leader of men, statesmen, philosopher, or poet, that owes this bounden duty to mankind. Every rustic who delivers in the village alehouse his slow, infrequent sentences, may help to kill or keep alive the fatal superstitions which clog his race. Every hard-worked wife of an artisan may transmit to her children beliefs which shall knit society together, or rend it in pieces. No simplicity of mind, no obscurity of station, can escape the universal duty of questioning all that we believe. It is true that this duty is a hard one, and the doubt which comes out of it is often a very bitter thing. It leaves us bare and powerless where we thought that we were safe and strong. To know all about anything is to know how to deal with it under all circumstances. We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. And if we have supposed ourselves to know all about anything, and to be capable of doing what is fit in regard to it, we naturally do not like to find that we are really ignorant and powerless, that we have to begin again at the beginning, and try to learn what the thing is and how it is to be dealt with — if indeed anything can be learnt about it. It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting."
"No man holding a strong belief on one side of a question, or even wishing to hold a belief on one side, can investigate it with such fairness and completeness as if he were really in doubt and unbiased; so that the existence of a belief not founded on fair inquiry unfits a man for the performance of this necessary duty. Nor is it that truly a belief at all which has not some influence upon the actions of him who holds it. He who truly believes that which prompts him to an action has looked upon the action to lust after it, he has committed it already in his heart. If a belief is not realized immediately in open deeds, it is stored up for the guidance of the future. It goes to make a part of that aggregate of beliefs which is the link between sensation and action at every moment of all our lives, and which is so organized and compacted together that no part of it can be isolated from the rest, but every new addition modifies the structure of the whole. No real belief, however trifling and fragmentary it may seem, is ever truly insignificant; it prepares us to receive more of its like, confirms those which resembled it before, and weakens others; and so gradually it lays a stealthy train in our inmost thoughts, which may someday explode into overt action, and leave its stamp upon our character for ever."
"Is mind a force? It is held by some that the will acts as the match to gunpowder, by setting loose a store of energy, the matter of the brain being in unstable equilibrium. But you cannot have in nature an absolutely unstable equilibrium [i.e., an equilibrium capable of being upset by an infinitesimal force], because the universe is not at rest [and every motion in the universe produces a finite change, however small, in the resultant force at every point of space]. Therefore if mind is force, operating in the way suggested, it must be able to create a determinate quantity of energy. This is a supposition which, if true, would destroy its own evidence; for it would destroy the uniformity of nature, on which all of inference ultimately rests."
"It might be said to the agitator, "However convinced you were of the justice of your cause and the truth of your convictions, you ought not to have made a public attack upon any man's character until you had examined the evidence on both sides with the utmost patience and care." In the first place, let us admit that, so far as it goes, this view of the case is right and necessary; right, because even when a man's belief is so fixed that he cannot think otherwise, he still has a choice in the action suggested by it, and so cannot escape the duty of investigating on the ground of the strength of his convictions; and necessary, because those who are not yet capable of controlling their feelings and thoughts must have a plain rule dealing with overt acts."
"A bad action is always bad at the time when it is done, no matter what happens afterwards. Every time we let ourselves believe for unworthy reasons, we weaken our powers of self-control, of doubting, of judicially and fairly weighing evidence. We all suffer severely enough from the maintenance and support of false beliefs and the fatally wrong actions which they lead to, and the evil born when one such belief is entertained is great and wide. But a greater and wider evil arises when the credulous character is maintained and supported, when a habit of believing for unworthy reasons is fostered and made permanent. If I steal money from any person, there may be no harm done from the mere transfer of possession; he may not feel the loss, or it may prevent him from using the money badly. But I cannot help doing this great wrong towards Man, that I make myself dishonest. What hurts society is not that it should lose its property, but that it should become a den of thieves, for then it must cease to be society. This is why we ought not to do evil, that good may come; for at any rate this great evil has come, that we have done evil and are made wicked thereby. In like manner, if I let myself believe anything on insufficient evidence, there may be no great harm done by the mere belief; it may be true after all, or I may never have occasion to exhibit it in outward acts. But I cannot help doing this great wrong towards Man, that I make myself credulous. The danger to society is not merely that it should believe wrong things, though that is great enough; but that it should become credulous, and lose the habit of testing things and inquiring into them; for then it must sink back into savagery."
"The harm which is done by credulity in a man is not confined to the fostering of a credulous character in others, and consequent support of false beliefs. Habitual want of care about what I believe leads to habitual want of care in others about the truth of what is told to me. Men speak the truth of one another when each reveres the truth in his own mind and in the other's mind; but how shall my friend revere the truth in my mind when I myself am careless about it, when I believe thing because I want to believe them, and because they are comforting and pleasant? Will he not learn to cry, "Peace," to me, when there is no peace? By such a course I shall surround myself with a thick atmosphere of falsehood and fraud, and in that I must live. It may matter little to me, in my cloud-castle of sweet illusions and darling lies; but it matters much to Man that I have made my neighbours ready to deceive. The credulous man is father to the liar and the cheat; he lives in the bosom of this his family, and it is no marvel if he should become even as they are."
"In March 1879 Clifford died at Madeira; six years afterwards a posthumous work is for the first time placed before the public. ...The original work as planned by Clifford was to have been entitled The First Principles of the Mathematical Sciences Explained to the Non-Mathematical, and to have contained six chapters, on Number, Space, Quantity, Position, Motion, and Mass respectively. Of the projected work Clifford in the year 1875 dictated the chapters on Number and Space completely, the first portion of the chapter on Quantity, and somewhat later nearly the entire chapter on Motion. The first two chapters were afterwards seen by him in proof, but never finally revised. Shortly before his death he expressed a wish that the book should only be published after very careful revision and that its title should be changed to The Common Sense of the Exact Sciences."
"Is a physical force, such as the attraction of earth, analogous to our "exertion of force" in muscular work? No, for the sensation of muscular effort is complicated. It involves nerve and muscle, which we know not to be present in the simpler cases, e.g., the motion of a stone let fall. To talk of pushing or pulling in such a case is a personification of external nature."
"On 24 March 1877 Annie (Besant) worked with Bradlaugh to republish Dr Charles Knowlton’s Fruits of Philosophy [1832] (a pamphlet that advocated the use of contraceptive practice); an act that led to the arrest of Besant and Bradlaugh on 6 April 1877 for transgressing the Obscene Publications Act 1857. The following ‘Obscenity trial’ was held on 18 June... both were proclaimed guilty. However, the sentence was overturned on a technicality so Besant and Bradlaugh were able to walk free. The arrest and trial were widely publicised across the country...the associated press coverage succeeded in propelling the pamphlet’s informative advice far beyond their initial reach... 1891 saw the death of Charles Bradlaugh who had become one of Annie’s closest and longest friends. Perhaps in recognition of this, this is the year in which Annie chose to bring her autobiography to an end when she was writing it in 1893, aged 46."
"Without free speech no search for Truth is possible; without free speech no discovery of Truth is useful; without free speech progress is checked, and the nations no longer march forward towards the nobler life which the future holds for man. Better a thousandfold abuse of free speech than denial of free speech. The abuse dies in a day; the denial slays the life of the people and entombs the hope of the race."
"Known as the "boy orator" of secular and atheistic circles in his youth, trained in the rough school of public disputation, a professional agitator of the most accomplished type, he created an extraordinary effect by the speech which he made when called to the bar of the House in June, 1880—a speech described by Mr. Gladstone in his letter to the Queen as "the address of a consummate speaker." Later, when he obtained an uncontested entrance into the House, he impressed it greatly with his courage, sincerity, and oratorical power. Traces of his early career flashed out in his complete disregard of the aspirate when excited, and he had a peculiar trick of standing with his right leg raised upon the bench and his elbow resting upon it as he addressed the House. His towering bulk and resounding voice (which almost equalled the thunder of Mr. John Burns) added to the impression of weight and power, and I can well believe that had he pursued less violent lines of agitation or been identified with more popular causes, he might have obtained an influence with the democracy second only to that of Daniel O'Connell."
"The Bible God I deny; the Christian God I disbelieve in; but I am not rash enough to say there is no God as long as you tell me you are unprepared to define God to me."
"Mr. Bradlaugh, the new member for Northampton, who now forced the question forward, as O'Connell had forced forward the civil equality of catholics, and Rothschild and others the civil equality of Jews, was a free-thinker of a daring and defiant type. Blank negation could go no further. He had abundant and genuine public spirit, and a strong love of truth according to his own lights, and he was both a brave and a disinterested man."
"I know one thing... Ken Livingstone is a folk hero."
"[Pigeons are] rats with wings."
"He has every right to his own view but not to express it when he is mayor of this city."
""One day the world will know that #RedKen was right"."
"Today Livingstone said that Hitler supported Zionism. Most people know that Zionism was in fact a response to antisemitism; most people know that Hitler wasn't in the business of responding to antisemitism but was himself the greatest antisemite of all time. Livingstone smears Jews, at least those who refuse to identify as anti-Zionist, by saying that they're like Nazis. He encourages people on the left and in the student movement to relate to Jews as though they were Nazis; unless they disavow Israel. Antisemitism? No, not at all. Just criticism. ... The Livingstone Formulation is named after Ken Livingstone. ... [It] conflates anything allegedly antisemitic, in this case repeatedly insulting a Jewish reporter by comparing him to a Nazi, into the category of legitimate criticism of Israel. Secondly, it goes further than accusing people who raise the issue of antisemitism of being wrong; it accuses them of being wrong on purpose; of crying wolf, of playing the antisemitism card. It alleges an intent, often a collective intent and so a conspiracy, to mobilise Jewish victim-power for illegitimate purposes."
"First of all, I've never heard of the fellow. Second, I'm not going to dignify it with a response."
"We look to the left and to the right And we need help but nobody's in sight Where is the man that we all need Tell him he's to come and rescue me."
"[The former Labour Party general secretary, Margaret McDonagh had died a few days before] Take her most controversial political battle. She helped exclude Ken Livingstone from the Labour candidacy for London mayor in 2000. As general secretary she took most of the blame for it. He won as an independent and she was accused of being "a control freak". At the time this was seen as a grotesque political error. I saw it differently then. And I do now. Livingstone shouldn't have been the Labour candidate for anything and it was worth losing, and enduring the political attacks, to assert that."
"When the Labour Herald printed a foully anti-semitic cartoon Mr Kenneth Livingstone, boss of the GLC, not only defended its publication, but said that the only thing he regretted about it was that it did not go far enough."
"Ken is the man that we all need Ken is the leader of the GLC!"
"I am not in favour of any parental choice in education. You will go to your local school."
"When Hitler won his election in 1932 his policy then was that Jews should be moved to Israel. He was supporting Zionism before he went mad and ended up killing six million Jews."
"I think Londoners find it bizarre that ten weeks after the allegations in the Evening Standard, you haven't questioned Lee [Jasper]. All these questions about Lee — he can come down from his office now and answer them, and you sanctimonious hypocrites are dragging this out so the lies can carry on in the Standard, you're not talking about Lee coming here 'till March. Bring him here today. Ask him your questions. Let Londoners see the answers. You're dragging this out for electoral purposes. Sanctimonious hypocrites, every one of you."
"One thing that Chairman Mao did was to end the appalling foot binding of women. That alone justifies the Mao Tse-tung era."
"One of the things that Chávez did when he came to power, he didn’t kill all the oligarchs. There was about 200 families who controlled about 80% of the wealth in Venezuela. He allowed them to live, to carry on. I suspect a lot of them are using their power and control over imports and exports to make it difficult and to undermine Maduro."
"You're a disgusting racist, you're rewriting history. A Nazi apologist. A Nazi apologist. You're a disgusting Nazi apologist, Livingstone."
"Perhaps if they're not happy here they can go back to Iran and try their luck with ayatollahs, if they don't like the planning regime or my approach."
"It would actually be quite nice if the American ambassador in Britain could pay the charge that everybody else is paying and not actually try and skive out of it like some chiselling little crook."
"To take such generous contracts and screw them up so dramatically must suggest that these are the most probably the worst business people ever assembled in one place to run anything. … the civil servants were taken to the cleaners and on the face of it you still end up with a £750 million overspend based on your mismanagement of them. I think they should be sacked, hung drawn and quartered, thrown out of the country and the whole thing (the London Underground) returned to public ownership. I saw that they (Metronet management) wanted to talk to the Mayor about this — wasting their breath sunshine! — they can go out and raise the money amongst their shareholders who came here to get their snout in the trough — they screwed it up; they are not getting any of our money!"
"If you go back a couple of hundred years to when the European cities really started to grow and peasants left the land to seek their future in the cities there was a saying that “city air makes you free” and the people who have come to London all races, creeds and colours have come for that. This is a city that you can be yourself as long as you don’t harm anyone else. You can live your life as you chose to do rather than as somebody else tells you to do. It is a city in which you can achieve your potential. That, I think, is our strength and that is what the bombers seek to destroy. They fear that freedom, they fear a world in which the individual makes their own life choices and their own moral value judgements and that is what they seek to snuff out. But they will fail."
"You can't expect to work for the Daily Mail group and have the rest of society treat with you respect as a useful member of society, because you are not."
"I want to say one thing specifically to the world today. This was not a terrorist attack against the mighty and the powerful. It was not aimed at presidents or prime ministers. It was aimed at ordinary, working-class Londoners — black and white, Muslim and Christian, Hindu and Jew, young and old — indiscriminate attempt to slaughter, irrespective of any considerations for age, for caste, for religion or whatever. That isn't an ideology, it isn't even a perverted faith, it is just indiscriminate attempt at mass murder — and we know what the objective is. They seek to divide Londoners. They seek to turn Londoners against each other."
"All racist and anti-semitic attacks must be stamped out. However, the reality is that the great bulk of racist attacks in Europe today are on black people, Asians and Muslims — and they are the primary targets of the extreme right. For 20 years Israeli governments have attempted to portray anyone who forcefully criticises the policies of Israel as anti-semitic. The truth is the opposite: the same universal human values that recognise the Holocaust as the greatest racist crime of the 20th century require condemnation of the policies of successive Israeli governments — not on the absurd grounds that they are Nazi or equivalent to the Holocaust, but because ethnic cleansing, discrimination and terror are immoral. They are also fuelling anger and violence across the world. For a mayor of London not to speak out against such injustice would not only be wrong — but would also ignore the threat it poses to the security of all Londoners."
"To avoid manufactured misunderstandings, the policies of Israeli governments are not analogous to Nazism. They do not aim at the systematic extermination of the Palestinian people, in the way Nazism sought the annihilation of the Jews."
"Today the Israeli government continues seizures of Palestinian land for settlements, military incursions into surrounding countries and denial of the right of Palestinians expelled by terror to return. Ariel Sharon, Israel's prime minister, is a war criminal who should be in prison, not in office. Israel's own Kahan commission found that Sharon shared responsibility for the Sabra and Shatila massacres."
"Finally, I wish to speak, through you, directly to those who came to London today to take life. I know that you personally do not fear to give your own life in exchange for taking others — that is why you are so dangerous. But I know you do fear that you may fail in your long-term objective to destroy our free society, and I can show you why you will fail. In the days that follow look at our airports, look at our sea ports and look at our railway stations, and even after your cowardly attack, you will see that people from the rest of Britain, people from around the world will arrive in London to become Londoners and to fulfill their dreams and achieve their potential. They choose to come to London, as so many have come before because they come to be free, they come to live the life they choose, they come to be able to be themselves. They flee you because you tell them how they should live. They don't want that and nothing you do, however many of us you kill, will stop that flight to our cities where freedom is strong and where people can live in harmony with one another. Whatever you do, however many you kill, you will fail."
"Racism is a uniquely reactionary ideology, used to justify the greatest crimes in history — the slave trade, the extermination of all original inhabitants of the Caribbean, the elimination of every native inhabitant of Tasmania, apartheid. The Holocaust was the ultimate, "industrialised" expression of racist barbarity. Racism serves as the cutting edge of the most reactionary movements. An ideology that starts by declaring one human being inferior to another is the slope whose end is at Auschwitz. That is why I detest racism."
"Oliver Finegold: Mr Livingstone, Evening Standard. How did it ... Ken Livingstone: Oh, how awful for you. Finegold: How did tonight go? Livingstone: Have you thought of having treatment? Finegold: How did tonight go? Livingstone: Have you thought of having treatment? Finegold: Was it a good party? What does it mean for you? Livingstone: What did you do before? Were you a German war criminal? Finegold: No, I'm Jewish. I wasn't a German war criminal. Livingstone: Ah … right. Finegold: I'm actually quite offended by that. So, how did tonight go? Livingstone: Well you might be, but actually you are just like a concentration camp guard. You're just doing it 'cause you're paid to, aren't you? Finegold: Great. I've you on record for that. So how did tonight go? Livingstone: It's nothing to do with you because your paper is a load of scumbags. Finegold: "How did tonight go?" Livingstone: It's reactionary bigots ... Finegold: I'm a journalist. I'm doing my job. Livingstone: … and who supported fascism. Finegold: I'm only asking for a simple comment. I'm only asking for a comment. Livingstone: Well, work for a paper that isn't ... Finegold: I'm only asking for a comment. Livingstone: … that had a record of supporting fascism. Finegold: You've accused me ..."
"It may very well be offensive, and that is a matter of personal judgment, but it was not racist. I have been through several media firestorms and I have taken the view that if I made a mistake I apologise. But I am not going to apologise if I don't think I have done anything wrong. It would be easy to buy off media pressure by lying but I am not going to do it."
"When you see someone trying to manoeuvre it round the school gates you have to think, you are a complete idiot."
"In this city 300 languages are spoken and the people that speak them live side by side in harmony. This city typifies what I believe is the future of the human race and a future where we grow together and we share and we learn from each other."
"The American agenda is sweeping everything before it, and although it's not perfect, the EU is better on environmental issues. It's a less rapacious form of capitalism."
