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 proposition is a proposition belief which would never lead to such disappointment so long as the proposition is not understood otherwise than it was intended.”
—Charles Sanders Peirce (1839–1914)
