“The word 'tradition' covered it all, as it covered so many things, some useful, some foolish.”

“But life is glorious when it is happy; days are carefree when they are happy; the interplay of thought and imagination is far superior to that of muscle and sinew. Let me tell you, if you don't know it from your own experience, that reading a good book, losing yourself in the interest of words and thoughts, is for some people (me, for instance) an incredible intensity of happiness.”

“One might suppose that reality must be held to at all costs. However, though that may be the moral thing to do, it is not necessarily the most useful thing to do. The Greeks themselves chose the ideal over the real in their geometry and demonstrated very well that far more could be achieved by consideration of abstract line and form than by a study of the real lines and forms of the world; the greater understanding achieved through abstraction could be applied most usefully to the very reality that was ignored in the process of gaining knowledge.”

“Let them all come,' said the Commdor, expansively. 'A symbolic friendly union of our nations. It will give us a chance for further friendly discussion. But one thing.' his face lengthened and grew stern, 'none of your religion. Don't think that all this is an entering wedge for the missionaries.''Commdor,' said Mallow, dryly, 'I give you my word that religion would cut my profits.”

“Fighting and scars are part of a trader's overhead. But fighting is only useful when there's money at the end, and if I can get it without, so much the sweeter.”

“And just how did you arrive at that remarkable conclusion, Mr. Mayor?""In a rather simple way. It merely required the use of that much-neglected commodity -- common sense. You see, there is a branch of human knowledge known as symbolic logic, which can be used to prune away all sorts of clogging deadwood that clutters up human language.""What about it?" said Fulham."I applied it. Among other things, I applied it to this document here. I didn't really need to for myself because I knew what it was all about, but I think I can explain it more easily to five physical scientists by symbols rather than by words."Hardin removed a few sheets of paper from the pad under his arm and spread them out. "I didn't do this myself, by the way," he said. "Muller Holk of the Division of Logic has his name signed to the analyses, as you can see."Pirenne leaned over the table to get a better view and Hardin continued: "The message from Anacreon was a simple problem, naturally, for the men who wrote it were men of action rather than men of words. It boils down easily and straightforwardly to the unqualified statement, when in symbols is what you see, and which in words, roughly translated is, 'You give us what we want in a week, or we take it by force.'"There was silence as the five members of the Board ran down the line of symbols, and then Pirenne sat down and coughed uneasily.Hardin said, "No loophole, is there, Dr. Pirenne?""Doesn't seem to be.”

“How often people speak of art and science as though they were two entirely different things, with no interconnection. An artist is emotional, they think, and uses only his intuition; he sees all at once and has no need of reason. A scientist is cold, they think, and uses only his reason; he argues carefully step by step, and needs no imagination. That is all wrong. The true artist is quite rational as well as imaginative and knows what he is doing; if he does not, his art suffers. The true scientist is quite imaginative as well as rational, and sometimes leaps to solutions where reason can follow only slowly; if he does not, his science suffers.”
