Doubt/law

Famous quotes containing the words doubt and/or law:

“Much of the wisdom of the world is not wisdom, and the most illuminated class of men are no doubt superior to literary fame, and are not writers.”
—Ralph Waldo Emerson (1803–1882)

“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)
