Famous quotes containing the words arithmetic and/or logic:
“Your discovery of the contradiction caused me the greatest surprise and, I would almost say, consternation, since it has shaken the basis on which I intended to build my arithmetic.... It is all the more serious since, with the loss of my rule V, not only the foundations of my arithmetic, but also the sole possible foundations of arithmetic seem to vanish.”
—Gottlob Frege (1848–1925)
“It is the logic of our times,
No subject for immortal verse—
That we who lived by honest dreams
Defend the bad against the worse.”
—Cecil Day Lewis (1904–1972)
