Famous quotes containing the words breast and/or development:
“Fergus rules the brazen cars,
And rules the shadows of the wood,
And the white breast of the dim sea
And all dishevelled wandering stars.”
—William Butler Yeats (1865–1939)
“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)
