Sec. XIII. Just as Pemptides had left off, and our father was about to answer his question, another messenger came from the town, sent by Ismenodora to summon Anthemion, for the tumult had increased, and there was a difference of opinion between the superintendents of the gymnasium, one thinking they ought to demand the liberation of Baccho, the other thinking they ought not to interfere. Anthemion got up at once and went off. And our father, addressing Pemptides especially, said, "You seem to me, my dear Pemptides, to be handling a great and bold matter, or rather to be discussing things that ought not to be discussed, in asking for a reason in each case for our opinion about the gods. Our ancient and hereditary faith is sufficient, a better argument than which we cannot either utter or find, 'Not e'en if wisdom in our brains resides;'[84] but if this common foundation and basis of all piety be disturbed, and its stability and time-honoured ideas be unsettled, it becomes undermined and is suspected by everybody. You have heard, of course, what hot water Euripides got into, when he wrote at the beginning of his 'Melanippe,' 'Zeus, whosoe'er he is, I do not know Except by hearsay,'[85] but if he changed the opening line, he had confidence, it seems, that his play would go down with the public uncommonly well,[86] so he altered it into 'Zeus the divine, as he is truly called.'[87] And what difference is there between calling in question the received opinion about Zeus or Athene, and that about Love? For it is not now for the first time that Love asks for an altar and sacrifices, nor is he a strange god introduced by foreign superstition, as some Attis or Adonis, furtively smuggled in by hermaphrodites and women, and secretly receiving honours not his own, to avoid an indictment among the gods for coming among them under false pretences. And when, my friend, you hear the words of Empedocles, 'Friendship is there too, of same length and breadth, But with the mind's eye only can you see it, Till with the sight your very soul is thralled,' you must suppose that they refer to Love. For this god is invisible, but to be extolled by us as one of the very oldest gods. And if you demand proofs about every one of the gods, laying a profane hand on every temple, and bringing a learned doubt to every altar, you will scrutinize and pry into everything. But we need not go far to find Love's pedigree. 'See you how great a goddess Aphrodite is? She 'tis that gave us and engendered Love, Whereof come all that on the earth do live.'[88]
