The death of the good is the beginning of another life; for life is a twofold thing, one life being in the body, corruptible; the other without the body, incorruptible. Therefore one wicked man surely dies the death, who while still breathing and among the living is in reality long since buried, so as to retain in himself no single spark of real life, which is perfect virtue. But a good man, who deserves so high a title, does not surely die, but has his life prolonged, and so attains to an eternal end.
