Proposition True

Famous quotes containing the words proposition and/or true:

“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)

“A true Friendship is as wise as it is tender. The parties to it yield implicitly to the guidance of their love, and know no other law nor kindness.”
—Henry David Thoreau (1817–1862)
