Equivalence Class Structure

Famous quotes containing the words class and/or structure:

“He has more to impart than to receive from his generation. He is another such a strong and finished workman in his craft as Samuel Johnson was, and, like him, makes the literary class respectable.”
—Henry David Thoreau (1817–1862)

“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)
