Note 17 — Introduction To The Phædo.
Henry Cary translation
Simmias and Cebes17 both agree in admitting that Socrates has proved the pre-existence of the soul, but insist that he has not shown it to be immortal, for that nothing hinders but that, according to the popular opinion, it may be dispersed at the dissolution of the body. To which Socrates replies, that if their former admissions are joined to his last argument, the immortality, as well as the pre-existence, of the soul has been sufficiently proved. For if it is true that any thing living is produced from that which is dead, then the soul must exist after death, otherwise it could not be produced again.
