Equivalence Class Structure

Famous quotes containing the words class and/or structure:

“A poet is no rattlebrain, saying what comes uppermost, and, because he says every thing, saying, at last, something good; but a heart in unison with his time and country. There is nothing whimsical or fantastic in his production, but sweet and sad earnest, freighted with the weightiest convictions, and pointed with the most determined aim which any man or class knows of in his times.”
—Ralph Waldo Emerson (1803–1882)

“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
