Note 23 — Introduction To The Phædo.
Henry Cary translation
With this he closes his arguments in support of the soul's immortality. Cebes owns himself convinced, but Simmias, though he is unable to make any objection to the soundness of Socrates's reasoning, can not help still entertaining doubts on the subject. If, however, the soul is immortal, Socrates proceeds,23 great need is there in this life to endeavor to become as wise and good as possible. For if death were a deliverance from every thing, it would be a great gain for the wicked; but since the soul appears to be immortal, it must go to the place suited to its nature. For it is said that each person's demon conducts him to a place where he receives sentence according to his deserts.
