Famous quotes containing the words present and/or danger:
“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)
“There is danger that we lose sight of what our friend is absolutely, while considering what she is to us alone.”
—Henry David Thoreau (1817–1862)
