Famous quotes containing the words physical and/or society:
“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 (18481925)
“In the United States, it is now possible for a person eighteen years of age, female as well as male, to graduate from high school, college, or university without ever having cared for, or even held, a baby; without ever having comforted or assisted another human being who really needed help. . . . No society can long sustain itself unless its members have learned the sensitivities, motivations, and skills involved in assisting and caring for other human beings.”
—Urie Bronfenbrenner (b. 1917)
