" Plato summarizes his reply to equalitarianism in the formula: ‘Equal treatment of unequals must beget inequity’20; and this was developed by Aristotle into the formula ‘Equality for equals, inequality for unequals’. This formula indicates what may be termed the standard objection to equalitarianism; the objection that equality would be excellent if only men were equal, but that it is manifestly impossible since they are not equal, and since they cannot be made equal.
