Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

“The eyes that drew from me such fervent praise,
The arms and hands and feet and countenance
Which made me a stranger in my own romance
And set me apart from the well-trodden ways;”
—Petrarch (1304–1374)

“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)
