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)
“We find that even the parents who justify spanking to themselves are defensive and embarrassed about it....I suspect that deep in the memory of every parent are the feelings that had attended his own childhood spankings, the feelings of humiliation, of helplessness, of submission through fear. The parent who finds himself spanking his own child cannot dispel the ghosts of his own childhood.”
—Selma H. Fraiberg (20th century)
“The limits of prudence: one cannot jump out of a burning building gradually.”
—Mason Cooley (b. 1927)
