Do you, therefore, act so, and with confidence; for there is no merchandise more fair than this or dearer to Heaven which you can ever dispatch or Archedemus transport.
 
 Beware, however, lest these doctrines be ever divulged to uneducated people. A Pythagorean touch, cf. Horace’s odi profanum volgus et arceo. For there are hardly any doctrines, I believe, which sound more absurd than these to the vulgar, or, on the other hand, more admirable and inspired to men of fine disposition. For it is through being repeated and listened to frequently for many years that these doctrines are refined at length, like gold, with prolonged labor. But listen now to the most remarkable result of all. Quite a number of men there are
 who have listened to these doctrines—men capable of learning and capable also of holding them in mind and judging them by all sorts of tests—and who have been hearers of mine for no less than thirty years This would make Plato’s teaching go back to 393 B.C., i.e. five or six years before he founded the Academy—which seems improbable. and are now quite old; and these men now declare that the doctrines that they once held to be most incredible appear to them now the most credible, and what they then held most credible now appears the Opposite. So, bearing this in mind, have a care lest one day you should repent of what has now been divulged improperly. The greatest safeguard is to avoid writing and to learn by heart;
 for it is not possible that what is written down should not get divulged. For this reason I myself have never yet written anything on these subjects, and no treatise by Plato exists or will exist, but those which now bear his name belong to a Socrates become fair and young. This curious statement seems based on Plat. L. 7.341c , combined perhaps with an allusion to the Parmenides . Fare thee well, and give me credence; and now, to begin with, read this letter over repeatedly and then burn it up.
 So much, then, for that. You were surprised at my sending Polyxenus to you; but now as of old I repeat
 the same statement about Lycophron A contemporary Sophist. also and the others you have with you, that, as respects dialectic, you are far superior to them all both in natural intelligence and in argumentative ability; and I maintain that if any of them is beaten in argument, this defeat is not voluntary, as some imagine, but involuntary. All the same, it appears that you treat them with the greatest consideration and make them presents. So much, then, about these men; too much, indeed, about such as they!
 As for Philistion, A physician at the court of Dionysius. if you are making use of him yourself by all means do so;
			 but if not, lend him if possible to Speusippus Plato’s nephew, who succeeded him as head of the Academy. If, as seems probable, Speusippus was unknown to Dionysius until he went to Sicily with Plato in 361 B.C., this request seems strange. and send him home. Speusippus, too, begs you to do so; and Philistion also promised me, that, if you would release him, he would gladly come to Athens . Many thanks for releasing the man in the stone-quarries; and my request with regard to his household and Hegesippus, the son of Ariston, Nothing further is known of any of the persons here mentioned. is no hard matter; for in your letter you said that should anyone wrong him or them and you come to know of it you would not allow it. It is proper for me also to say what is true
 about Lysicleides; for of all those who have come to Athens from Sicily he is the only one who has not misrepresented your association with me; on the contrary, he always speaks nicely about past events and puts the best construction on them.
