List of Graphical Methods - Set Theory

Famous quotes containing the words set and/or theory:

“Freedom is slavery some poets tell us.
Enslave yourself to the right leader’s truth,
Christ’s or Karl Marx’, and it will set you free.”
—Robert Frost (1874–1963)

“By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.”
—Abraham Lincoln (1809–1865)
