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.
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.
We will continue to ignore political and economic forecasts, which are an expensive distraction for many investors and
businessmen. Thirty years ago, no one could have foreseen the huge expansion of the Vietnam War, wage and price controls, two oil shocks, the resignation of a president, the dissolution of the Soviet Union, a one-day drop in the Dow of 508 points, or treasury bill yields fluctuating between 2.8% and 17.4%.
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.
APHORISM, n. Predigested wisdom. The flabby wine-skin of his brain Yields to some pathologic strain, And voids from its unstored abysm The driblet of an aphorism. "The Mad Philosopher," 1697
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.
Do not yield to Satan's enticements; rather, stand firm for truth. The unsatisfied yearnings of the soul will not be met by a never-ending quest for joy amidst the thrills of sensation and vice. Vice never leads to virtue. Hate never promotes love. Cowardice never gives courage. Doubt never inspires faith.
