Famous quotes containing the words variables and/or defined:
“The variables of quantification, ‘something,’ ‘nothing,’ ‘everything,’ range over our whole ontology, whatever it may be; and we are convicted of a particular ontological presupposition if, and only if, the alleged presuppositum has to be reckoned among the entities over which our variables range in order to render one of our affirmations true.”
—Willard Van Orman Quine (b. 1908)
“Manners have been somewhat cynically defined to be a contrivance of wise men to keep fools at a distance. Fashion is shrewd to detect those who do not belong to her train, and seldom wastes her attentions.”
—Ralph Waldo Emerson (1803–1882)
