When I had said this, Demetrius remarked, Lamprias gives the right advice; for The gods make us to slip by many forms not of tricks, as Euripides Cf. Nauck, Trag. Graec. Frag. p. 674, Euripides, no. 972. says, but of facts, whenever we make bold to pronounce opinions about such matters as if we understood them. But the discussion must be carried back, as the same writer says, Cf. the note on 390 c, supra . to the assumption made at the beginning. For what was said then, that when the demigods withdraw and forsake the oracles, these lie idle and inarticulate like the instruments of musicians, raises another question of greater import regarding the causative means and power which they employ to make the prophetic priests and priestesses possessed by inspiration and able to present their visions. For it is not possible to hold that the desertion by the demigods is the reason for the silence of the oracles unless we are convinced as to the manner in which the demigods, by having the oracles in their charge and by their presence there, make them active and articulate. Here Ammonius joined in and said, Do you really think that the demigods are aught else than souls that make their rounds, in mist apparelled, as Hesiod Works and Days , 125. says? To my mind the difference between man and man in acting tragedy or comedy is the difference between soul and soul arrayed in a body suitable for its present life. It is, therefore, not at all unreasonable or even marvellous that souls meeting souls should create in them impressions of the future, exactly as we do not convey all our information to one another through the spoken word, but by writing also, or merely by a touch or a glance, we give much information about what has come to pass and intimation of what is to come. Unless it be, Lamprias, that you have another story to tell. For not long ago a rumour reached us about your having had a long talk on these subjects with strangers at Lebadeia, but the man who told of it could recall none of it with exactness. You need not be surprised, said I, since many activities and distractions occurring in the midst of it, because it was a day for oracles and sacrifice, made our conversation desultory and disconnected. But now, said Ammonius, you have listeners with nothing to distract them and eager to seek and gain information on this point or that; all strife and contention is banished and a sympathetic hearing and freedom of statement, as you observe, is granted for all that may be said. 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.
