“Is there any knowledge in the world which is so certain that no reasonable man could doubt it?”

“Among these surprising possibilities, doubt suggests that perhaps there is no table at all. Philosophy, if it cannot answer so many questions as we could wish, has at least the power of asking questions which increase the interest of the world, and show the strangeness and wonder lying just below the surface even in the commonest things of daily life.”

“I do not pretend to be able to prove that there is no God. I equally cannot prove that Satan is a fiction. The Christian god may exist; so may the gods of Olympus, or of ancient Egypt, or of Babylon. But no one of these hypotheses is more probable than any other: they lie outside the region of even probable knowledge, and therefore there is no reason to consider any of them.”

“Religious toleration, to a certain extent, has been won, because people have ceased to consider religion so important as it was once thought to be. But in politics and economics, which have taken the place formerly occupied by religion, there is a growing tendency to persecution, which is not by any means confined to one party.”

“Most of the greatest evils that man has inflicted upon man have come through people feeling quite certain about something which, in fact, was false.”

“Philosophy, though unable to tell us with certainty what is the true answer to the doubts which it raises, is able to suggest many possiblities which enlarge our thoughts and free them from the tyranny of custom. Thus, while diminishing our feeling of certainty as to what things are, it greatly increases our knowledge as to what the may be; it removes the somewhat arrogant dogmatism of those who have never travelled into the region of liberating doubt, and it keeps alive our sense of wonder by showing familar things in an unfamilar aspect”

“In the first place, there is no point whatever in being able to spell anything. Shakespeare and Milton could not spell; Marie Corelli and Alfred Austen could. Spelling is thought desirable partly for snobbish reasons, as an easy way of distinguishing the “educated” from the “uneducated”; partly, like correct clothes, as a part of herd domination; partly because the devotee of natural law feels pain in the spectacle of any sphere in which individual liberty remains.”
