Famous quotes containing the words show and/or development:
“O power of fantasy that steals our minds from things outside, to leave us unaware, although a thousand trumpets may blow loud—what stirs you if the senses show you nothing? Light stirs you, formed in Heaven, by itself, or by His will Who sends it down to us.”
—Dante Alighieri (1265–1321)
“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)
