Quantity Theory

Famous quotes containing the words quantity and/or theory:

“If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning, concerning matter of fact and existence? No. Commit it then to flames: for it can contain nothing but sophistry and illusion.”
—David Hume (1711–1776)

“Could Shakespeare give a theory of Shakespeare?”
—Ralph Waldo Emerson (1803–1882)
