Famous quotes containing the words physical, memory and/or limits:
“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)
“I hope there will be no effort to put up a shaft or any monument of that sort in memory of me or of the other women who have given themselves to our work. The best kind of a memorial would be a school where girls could be taught everything useful that would help them to earn an honorable livelihood; where they could learn to do anything they were capable of, just as boys can. I would like to have lived to see such a school as that in every great city of the United States.”
—Susan B. Anthony (1820–1906)
“As nature requires whirlwinds and cyclones to release its excessive force in a violent revolt against its own existence, so the spirit requires a demonic human being from time to time whose excessive strength rebels against the community of thought and the monotony of morality ... only by looking at those beyond its limits does humanity come to know its own utmost limits.”
—Stefan Zweig (18811942)
