Famous quotes containing the word lead:
“In sum, all actions and habits are to be esteemed good or evil by their causes and usefulness in reference to the commonwealth, and not by their mediocrity, nor by their being commended. For several men praise several customs, and, contrarily, what one calls vice, another calls virtue, as their present affections lead them.”
—Thomas Hobbes (1579–1688)
“The only ways of enquiry that lead to knowledge ... the one way assuming that being is and that it is impossible for it not to be, is the trustworthy path, for truth attends it. The Other, that non-being is and that it necessarily is, I call a wholly incredible course, since thou canst not recognize not-being ... nor couldst thou speak of it, for though and being are the same things.”
—Parmenides (c. 515–480 B.C.)
“I have often been downcast, but never in despair; I regard our hiding as a dangerous adventure, romantic and interesting at the same time. In my diary I treat all the privations as amusing. I have made up my mind now to lead a different life from other girls and, later on, different from ordinary housewives. My start has been so very full of interest, and that is the sole reason why I have to laugh at the humorous side of the most dangerous moments.”
—Anne Frank (1929–1945)
