Famous quotes containing the words proposition and/or true:
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“It is thought a disgrace to love unrequited. But the great will see that true love cannot be unrequited. True love transcends the unworthy object, and dwells and broods on the eternal, and when the poor interposed mask crumbles, it is not sad, but feels rid of so much earth, and feels its independency the surer.”
—Ralph Waldo Emerson (1803–1882)
