There, into Acheron runs not alone Dread Pyriphlegethon, but Cocytus loud, From Styx derived; there also stands a rock, At whose broad base the roaring rivers meet. Odyssey. B. X.] there they cry out to and invoke, some, those whom they slew, others, those whom they injured; and, invoking them, they entreat and implore them to suffer them to go out into the lake and to receive them; and if they persuade them, they go out, and are freed from their sufferings; but if not, they are borne back to Tartarus, and thence again to the rivers, and they do not cease from suffering this until they have persuaded those whom they have injured--for this sentence was imposed on them by the judges. But those who are found to have lived an eminently holy life--these are they who, being freed and set at large from these regions in the earth as from a prison--arrive at the pure abode above, and dwell on the upper parts of the earth. And among these, those who have sufficiently purified themselves by philosophy shall live without bodies throughout all future time, and shall arrive at habitations yet more beautiful than these, which it is neither easy to describe, nor at present is there sufficient time for the purpose. "For the sake of these things which we have described we should use every endeavor to acquire virtue and wisdom in this life, for the reward is noble and the hope great. To affirm positively, however, that these things are exactly as I have described them, does not become a man of sense; but that either this, or something of the kind, takes place with respect to our souls and their habitations--since our soul is certainly immortal--appears to me most fitting to be believed, and worthy the hazard for one who trusts in its reality; for the hazard is noble, and it is right to allure ourselves with such things, as with enchantments; for which reason I have prolonged my story to such length. On account of these things, then, a man ought to be confident about his soul, who during this life has disregarded all the pleasures and ornaments of the body as foreign from his nature, and who, having thought that they do more harm than good, has zealously applied himself to the acquirement of knowledge, and who, having adorned his soul not with a foreign but with its own proper ornaments--temperance, justice, fortitude, freedom, and truth-- thus waits for his passage to Hades as one who is ready to depart whenever destiny shall summon him."
