Famous quotes containing the words development and/or authority:
“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 authority of government, even such as I am willing to submit to,—for I will cheerfully obey those who know and can do better than I, and in many things even those who neither know nor can do so well,—is still an impure one: to be strictly just, it must have the sanction and consent of the governed. It can have no pure right over my person and property but what I concede to it.”
—Henry David Thoreau (1817–1862)
