Famous quotes containing the words apply and/or mask:

“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)

““It was the mask engaged your mind,
And after set your heart to beat,
Not what’s behind.””
—William Butler Yeats (1865–1939)
