Equivalence Class Structure

Famous quotes containing the words class and/or structure:

“But the strong and healthy yeoman and husbands of the land, the self-sustaining class of inventive and industrious men, fear no competition or superiority. Come what will, their faculty cannot be spared.”
—Ralph Waldo Emerson (1803–1882)

“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
