Development Act

Famous quotes containing the words development and/or act:

“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)

“Spirit is now a very fashionable word: to act with Spirit, to speak with Spirit, means only to act rashly, and to talk indiscreetly. An able man shows his Spirit by gentle words and resolute actions; he is neither hot nor timid.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
