simpler, and he would have distinguished between actual conditions and possibilities in Greece and his admittedly more or less utopian ideal.
EXCHANGE
Exchange in Greek economy held a very minor place, compared with its dominant importance in modern theory. It was discussed chiefly in a negative manner, as the object of the moral and aristocratic prejudice of Greek thinkers. We find, however, some appreciation of its true place in the economic life of a state. Plato divides trade, ἀλλαγή or ἀγοραστική, into αὐτοπωλική, which sells its own products, αὐτουργῶν, and μεταβλητική, which exchanges the products of others. He further divides the latter into καπηλική, the exchange within the state, which he calls one-half of all the exchange, and ἐμπορική, foreign commerce.205 He finds its origin in the division of labor, and in the mutual interdependence of men and states.206 He understands the necessity of the reciprocal attitude in international, as well as in private, exchange, and thus has a clearer insight than the mercantilists and some modern statesmen. A state must raise a surplus of its own products, so as to supply the other state from which it expects to have its own needs satisfied.207
