Equivalence Class Structure

Famous quotes containing the words class and/or structure:

“Sometimes I think that idlers seem to be a special class for whom nothing can be planned, plead as one will with them—their only contribution to the human family is to warm a seat at the common table.”

Become a verse? Is there in truth no beauty?
Is all good structure in a winding stair?
May no lines pass, except they do their duty
Not to a true, but painted chair?”
