Book 6
23
But the divine Plato, and Lycurgus the Lacedæmonian, not only forbad all costly ornaments to be introduced into their model states, but they would not permit even silver or gold to be brought into them, thinking that of the products of mines, iron and copper were sufficient, and banishing the other metals as injurious to those states which were in good order. But Zeno the Stoic, thinking everything unimportant except the legitimate and honest use of the precious metals, forbad either praying for or deprecating them; but still he recommended chiefly the use of those which were more commonly accessible and less superfluous; in order that men, having the dispositions of their minds formed so as neither to fear nor to admire anything which is not honourable on the one hand or discreditable on the other, should use only what is natural as much as possible, and yet should not fear what is of an opposite character, but abstain from such in obedience to reason and not to fear. For nature has not banished any of the above-mentioned things out of the world, but has made subterranean veins of these metals, the working of which is very laborious and difficult, in order that they who desire such things may arrive at the acquisition after toil and suffering; and that not only those men themselves who work in the mines, but those also who collect what has been extracted from the mines, may acquire this much wished for opulence at the expense of countless labours.
