Famous quotes containing the words abstract and/or level:
“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)
“To punish drug takers is like a drunk striking the bleary face it sees in the mirror. Drugs will not be brought under control until society itself changes, enabling men to use them as primitive man did: welcoming the visions they provided not as fantasies, but as intimations of a different, and important, level of reality.”
—Brian Inglis (b. 1916)
