of a bird or of a pig; and again, that this Falernian is only a little grape juice, and this purple robe some sheep’s wool dyed with the blood of a shellfish: such then are these impressions, and they reach the things themselves and penetrate them, and so we see what kind of things they are. Just in the same way ought we to act all through life, and where there are things which appear most worthy of our approbation, we ought to lay them bare and look at their worthlessness and strip them of all the words by which they are exalted. For outward show is a wonderful perverter of the reason, and when thou art most sure that thou art employed about things worth thy pains, it is then that it cheats thee most. Consider then what Crates says of Xenocrates himself.
Most of the things which the multitude admire are referred to objects of the most general kind, those which are held together by cohesion or natural organization, such as stones, wood, fig-trees, vines, olives.
But those which are admired by men who are a little more reasonable are referred to the things which are held together by a living principle, as flocks, herds.
Those which are admired by men who are still more instructed are the things which are held together by a rational soul, not however a universal soul, but rational so far as it is a soul skilled in some art, or expert in some other way, or simply rational so far as it possesses a number of slaves.
But he who values rational soul, a soul universal and fitted for political life, regards nothing else except this; and above all things he keeps his soul in a condition and in an activity conformable to reason and social life, and he cooperates to this end with those who are of the same kind as himself.
