Illness/physical

Famous quotes containing the words illness and/or physical:

“All signs of superhuman nature appear in man as illness or insanity.”
—Friedrich Nietzsche (1844–1900)

“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)
