Book 1 · Section 85

XXVII. (85) And it is worth while to raise the question why the two rivers the Pheison and the Gihon encircle certain countries, the one surrounding Evilat, and the other Ethiopia, while neither of the other rivers is represented as encompassing any country. The Tigris is indeed said to flow in front of the land of the Assyrians, but the Euphrates is not mentioned in connection with any country whatever. And yet in real truth the Euphrates does both encircle some countries, and has several also in front of it. But the truth is that the sacred writer is here speaking not of the river, but of the correction of manners. (86) It is necessary therefore to say that prudence and courage are able to raise a wall and a circle of fortification against the opposite evils, folly, and cowardice; and to take them captives: for both of them are powerless and easy to be taken. For the foolish man is easily to be defeated by the prudent one; and the coward falls before the valiant man. But temperance is unable to surround appetite and pleasure; for they are formidable adversaries and hard to be subdued. Do you not see that even the most temperate men are compelled by the necessities of their mortal body to seek meat and drink; and it is in those things that the pleasures of the belly have their existence. We must be content therefore to oppose and contend with the genus appetite. (87) And it is on this account that the river Tigris is represented as flowing in front of the Assyrians, that is to say temperance is in front of or arrayed against pleasure. But justice, according to which the river Euphrates is represented, neither besieges any one, nor draws lines of circumvallation round any one, nor opposes any one; --why so? Because justice is conversant about the distribution of things according to merit, and does not take the part either of accuser or of defendant, but acts as a judge. As therefore a judge does not desire beforehand to defeat any one, nor to oppose and make war upon any one; but delivers his own opinion and judges, deciding for the right, so also justice, not being the adversary of any one, distributes its due to every thing.
