### Famous quotes containing the words ring and/or theory:

“Generally, about all perception, we can say that a sense is what has the power of receiving into itself the sensible forms of things without the matter, in the way in which a piece of wax takes on the impress of a signet *ring* without the iron or gold.”

—Aristotle (384–323 B.C.)

“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)
