The best ideas are common property. It is better, of course, to know useless things than to know nothing. It is the nature of a great mind to be calm and undisturbed. Let tears flow of their own accord: their flowing is not inconsistent with inward peace and harmony. Most powerful is he who has himself in his own power. That which is never too often repeated, is never sufficiently learned. The comfort of having a friend may be taken away - but not that of having had one. He who has great power should use it lightly. There is a noble manner of being poor and who does not know it will never be rich. He who decides a case without hearing the other side, though he decides justly, cannot be considered just. |
