“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 widely spread belief is more likely to be foolish than sensible.”

Context: Look at this, again! Khedira plays it wide, Özil! Khedira again! Five, nil! This is utterly, beyond belief! Where is this goal scoring going to end? Well, if this was boxing? The referee would be stopping it, to save Brazil from further punishment. Five goals in the first twenty-nine minutes from a rampant Germany; Brazil have simply unraveled. Fred, here's Luiz Gustavo. Marcelo. Just need something, anything. To lift their confidence, but.

Context: The most curious social convention of the great age in which we live is the one to the effect that religious opinions should be respected. Its evil effects must be plain enough to everyone. All it accomplishes is (a) to throw a veil of sanctity about ideas that violate every intellectual decency, and (b) to make every theologian a sort of chartered libertine. No doubt it is mainly to blame for the appalling slowness with which really sound notions make their way in the world. The minute a new one is launched, in whatever field, some imbecile of a theologian is certain to fall upon it, seeking to put it down. The most effective way to defend it, of course, would be to fall upon the theologian, for the only really workable defense, in polemics as in war, is a vigorous offensive. But the convention that I have mentioned frowns upon that device as indecent, and so theologians continue their assault upon sense without much resistance, and the enlightenment is unpleasantly delayed.
There is, in fact, nothing about religious opinions that entitles them to any more respect than other opinions get. On the contrary, they tend to be noticeably silly. If you doubt it, then ask any pious fellow of your acquaintance to put what he believes into the form of an affidavit, and see how it reads…. “I, John Doe, being duly sworn, do say that I believe that, at death, I shall turn into a vertebrate without substance, having neither weight, extent nor mass, but with all the intellectual powers and bodily sensations of an ordinary mammal;... and that, for the high crime and misdemeanor of having kissed my sister-in-law behind the door, with evil intent, I shall be boiled in molten sulphur for one billion calendar years.” Or, “I, Mary Roe, having the fear of Hell before me, do solemnly affirm and declare that I believe it was right, just, lawful and decent for the Lord God Jehovah, seeing certain little children of Beth-el laugh at Elisha’s bald head, to send a she-bear from the wood, and to instruct, incite, induce and command it to tear forty-two of them to pieces.” Or, “I, the Right Rev. _____ _________, Bishop of _________, D. D., LL. D., do honestly, faithfully and on my honor as a man and a priest, declare that I believe that Jonah swallowed the whale,” or vice versa, as the case may be. No, there is nothing notably dignified about religious ideas. They run, rather, to a peculiarly puerile and tedious kind of nonsense. At their best, they are borrowed from metaphysicians, which is to say, from men who devote their lives to proving that twice two is not always or necessarily four. At their worst, they smell of spiritualism and fortune telling. Nor is there any visible virtue in the men who merchant them professionally. Few theologians know anything that is worth knowing, even about theology, and not many of them are honest. One may forgive a Communist or a Single Taxer on the ground that there is something the matter with his ductless glands, and that a Winter in the south of France would relieve him. But the average theologian is a hearty, red-faced, well-fed fellow with no discernible excuse in pathology. He disseminates his blather, not innocently, like a philosopher, but maliciously, like a politician. In a well-organized world he would be on the stone-pile. But in the world as it exists we are asked to listen to him, not only politely, but even reverently, and with our mouths open.
