"We tend quite rightly to associate an age with its newest and most original ideas, and there is no harm in this as long as we remember that only a few men, at that time, may have actually held those ideas, and that many decades, often amounting to centuries, may pass before those ideas have seeped down to wider and commoner levels of belief, thought, and feeling. So many 'hard-headed and realistic' men of today repeat what scientists were saying 100 years ago, and may know nothing about the outlook and prevailing moods of scientists today. And men in the street now assert beliefs originally found among the intellectuals of the 18th century. We may expect time-lags of various lengths."

“Because most children are highly imaginative, it is supposed by some that to reach maturity we ought to leave imagination behind, like the habit of smearing our faces with jam or chocolate. But an adult in whom imagination has withered is mentally lame and lopsided, in danger of turning into a zombie or a murderer. It is the creative imagination that has given our ruthless bloodthirsty species its occasional gleams of nobility, its hope of rising above the muck it spreads.”

“It's silly for young men to announce themselves as new types of humanity. . .and then give you nothing but stale communism. Old H.G. Wells has more new ideas than the lot of them.”

“I have lived longer than you. I have thought more, and I have suffered more. And I tell you there is more truth to the fundamental nature of things in the most foolish fairy tales than there is in any of your complaints against life.”

“I've been up and down and round about," said the Commodore, "and I've seen a lot of religions at work. And I don't like them. With all due respect, padre. As a matter of fact I'm not thinking about the Church of England, which is something different, something intended to keep the English decent and fairly comfortable and not likely to go tearing off into religion and making nuisances of themselves—”

“We cannot go forward and build up this new world order, and this is our war aim, unless we begin to think differently...one must stop thinking in terms of property and power and begin thinking in terms of community and creation. Property is the old-fashioned way of thinking of a country as a thing, and a collection of things in that thing, all owned by certain people and constituting property; instead of thinking of a country as the home of a living society with the community itself as the first test.”

“The appalling difficulty of examining the Time problem seems to me to be chiefly due to the fact that Time either changes into something else or quietly disappears from the examination room. Trying to keep it fixedly in view is like playing Wonderland croquet.”
