How often has not the parallel been drawn and the golden age of the Roman Empire, when the external brilliancy of life likewise dazzled the eye, notwithstanding that the social diagnosis could yield no other verdict than 'rotten to the very core'?
Intuition and concepts constitute... the elements of all our knowledge, so that neither concepts without an intuition in some way corresponding to them, nor intuition without concepts, can yield knowledge.
The earth is a machine which yields almost gratuitous service to every application of intellect. Every plant is a manufacturer of soil. In the stomach of the plant development begins. The tree can draw on the whole air, the whole earth, on all the rolling main. The plant is all suction-pipe,--imbibing from the ground by its root, from the air by its leaves, with all its might.
How do you measure whether or not a strategy of economic growth that is articulated by a very smart, capable economist actually yields growth? You can't. But you can influence.
I yield to your wishes. It is the privilege of the women whom we love more than they love us to make the men who love them ignore the ordinary rules of common-sense.
However we select from nature a complex [of phenomena] using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate (sufficient).... I do not doubt that the day will come when [general relativity], too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that this process of deepening theory has no limits.
I have really got it into my head to try to be United States Senator, and, if I could have your support, my chances would be reasonably good. But I know, and acknowledge, that you have as just claims to the place as I have; and therefore I cannot ask you to yield to me, if you are thinking of becoming a candidate, yourself. If, however, you are not, then I should like to be remembered affectionately by you; and also to have you make a mark for me with the Anti-Nebraska members down your way.
Humor is the great thing, the saving thing after all. The minute it crops up, all our hardnesses yield, all our irritations, and resentments flit away, and a sunny spirit takes their place.
Poets and men of action differ: the former yield to their feelings in order to reproduce them in lively colors, and therefore judge only ex post facto; the latter feel and judge at one and the same time.
