Route Description

Famous quotes containing the words route and/or description:
“By a route obscure and lonely,
Haunted by ill angels only,
Where an eidolon, named Night,
On a black throne reigns upright,
I have reached these lands but newly
From an ultimate dim Thule—
From a wild weird clime that lieth, sublime,
Out of space—out of time.”
—Edgar Allan Poe (1809–1849)
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
