The Pythagoreans enter the Ethics as holders of particular doctrines, each weighed and given a limited verdict. Here they have "more plausibility" than the Platonists for setting the one among the goods; in Book II evil is the unlimited, in a Pythagorean figure; in Book V their definition of justice as simple requital is rejected. Peters even tells the reader where the doctrine sits, with "[in their table of opposites]", a bracket that is his, not Aristotle's. Papus's Traité élémentaire, on this shelf, gives Pythagoras an Egyptian schooling and a whole psychology (a soul with reasoning, irascible and appetitive faculties, governed by four virtues), which is the scheme of Plato's Republic. Read together, the two books show how much the name gathered between Aristotle's report and 1888.
