Proposition True

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)

“The wit makes fun of other persons; the satirist makes fun of the world; the humorist makes fun of himself, but in so doing, he identifies himself with people—that is, people everywhere, not for the purpose of taking them apart, but simply revealing their true nature.”
—James Thurber (1894–1961)
