[Sidenote: _Eryxias._]
Much cannot be said in praise of the style or conception of the Eryxias.
It is frequently obscure; like the exercise of a student, it is full of
small imitations of Plato:—Phaeax returning from an expedition to Sicily
(cp. Socrates in the Charmides from the army at Potidaea), the figure of
the game at draughts, 395 B, borrowed from Rep. vi. 487, etc. It has also
in many passages the ring of sophistry. On the other hand, the rather
unhandsome treatment which is exhibited towards Prodicus is quite unlike
the urbanity of Plato.
Yet there are some points in the argument which are deserving of
attention. (1) That wealth depends upon the need of it or demand for
it, is the first anticipation in an abstract form of one of the great
principles of modern political economy, and the nearest approach to it
to be found in an ancient writer. (2) The resolution of wealth into its
simplest implements going on to infinity is a subtle and refined thought.
(3) That wealth is relative to circumstances is a sound conception.
(4) That the arts and sciences which receive payment are likewise to
be comprehended under the notion of wealth, also touches a question of
modern political economy. (5) The distinction of _post hoc_ and _propter
hoc_, often lost sight of in modern as well as in ancient times. These
metaphysical conceptions and distinctions show considerable power of
thought in the writer, whatever we may think of his merits as an imitator
of Plato.
