Development Test

Famous quotes containing the words development and/or test:

“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)

“To answer a question so as to admit of no reply, is the test of a man.”
—Ralph Waldo Emerson (1803–1882)
