De Defectu Oraculorum

As the others also joined in the request, I, after a moment of silence, continued, As a matter of fact, Ammonius, by some chance you happen to be the one who provided the opening and approach for what was said on that occasion. For if the souls which have been severed from a body, or have had no part with one at all, are demigods according to you and the divine Hesiod,[*](Works and Days, 123.)

Holy dwellers on earth and the guardian spirits of mortals,

why deprive souls in bodies of that power by virtue of which the demigods possess the natural faculty of knowing and revealing future events before they happen? For it is not likely that any power or portion accrues to souls when they have left the body, if they did not possess them before; but the souls always possess them; only they possess them to a slight degree while conjoined with the body, some of them being completely imperceptible and hidden, others weak and dim, and about as ineffectual and slow in operation as persons that try to see in a fog or to move about in water, and requiring much nursing and restoring of the functions that properly belong to them and the removal and clearing away of the covering which hides them. Just as the sun does not become bright when it bursts through the clouds, but is bright always, and yet in a fog appears to us indistinct and dim, even so the soul does not acquire the prophetic power when it goes forth from the body as from a cloud; it possesses that power even now, but is blinded by being combined and commingled with the mortal nature. We ought not to feel surprised or incredulous at this when we see in the soul, though we see naught else, that faculty which is the complement of prophecy, and which we call memory, and how great an achievement is displayed in preserving and guarding the past, or rather what has been the present, since nothing of all that has come to pass has any existence or substantiality, because the very instant when anything comes to pass, that is the end of it — of actions, words, experiences alike; for Time like an everflowing stream bears all things onward. But this faculty of the soul lays hold upon them, I know not how, and invests with semblance and being things not now present here. The oracle given to the Thessalians about Arnê[*](Cf. Thucydides, i. 12.) bade them note

A deaf man’s hearing, a blind man’s sight.

But memory is for us the hearing of deeds to which we are deaf and the seeing of things to which we are blind. Hence, as I said, it is no wonder that, if it has command over things that no longer are, it anticipates many of those which have not yet come to pass, since these are more closely related to it, and with these it has much in common; for its attachments and associations are with the future, and it is quit of all that is past and ended, save only to remember it.
