Famous quotes containing the words natural and/or law:
“No Vice or Wickedness, which People fall into from Indulgence to Desires which are natural to all, ought to place them below the Compassion of the virtuous Part of the World; which indeed often makes me a little apt to suspect the Sincerity of their Virtue, who are too warmly provoked at other Peoples personal Sins.”
—Richard Steele (1672–1729)
“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)
