A man did lead them on, a strong stout man, A honeyed speaker, sweet as melody Of tuneful grasshopper, who, seated high On Hecademus’ tree, unwearied sings. For the word academy was formerly spelt with E. Now our philosopher was a friend of Isocrates; and Praxiphanes composed an account of a conversation which took place between them, on the subject of poets, when Isocrates was staying with Plato in the country. X. And Aristoxenus says that he was three times engaged in military expeditions; once against Tanagra; the second time against Corinth, and the third time at Delium; and that in the battle of Delium he obtained the prize of pre-eminent valour. He combined the principles of the schools of Heraclitus, and Pythagoras and Socrates; for he used to philosophize on those things which are the subjects of sensation, according to the system of Heraclitus; on those with which intellect is conversant, according to that of Pythagoras; and on politics according to that of Socrates. XI. And some people, (of whom Satyrus is one,) say that he sent a commission to Sicily to Dion, to buy him three books of Pythagoras from Philolaus for a hundred minæ; for they say that he was in very easy circumstances, having received from Dionysius more than eighty talents, as Onetor also asserts in his treatise which is entitled, Whether a wise Man ought to acquire Gains. XII. And he was much assisted by Epicharmus the comic poet, a great part of whose works he transcribed, as Alcimus says in his essays addressed to Amyntas, of which there are four. And in the first of them he speaks as follows:—“And Plato appears to utter a great many of the sentiments of Epicharmus. Let us just examine. Plato says that that is an object of sensation, which is never stationary either as to its quality or its quantity, but which is always flowing and changing; as, for instance, if one take from any objects all number, then one cannot affirm that they are either equal, or of any particular things, or of what quality or quantity they are. And these things are of such a kind that they are always being produced, but that they never have any invariable substances.” But that is a subject for intellect from which nothing is taken, and to which nothing is added. And this is the nature of things eternal, which is always similar and the same. And, indeed, Epicharmus speaks intelligibly on the subject of what is perceived by the senses and by the intellect:— _A._ But the great Gods were always present, nor Did they at any moment cease to be; And their peculiar likeness at all times Do they retain, by the same principles. _B._ Yet chaos is asserted to have been The first existent Deity. _A._ How can that be? For ’tis impossible that we should find Any first principle arise from anything. _B._ Is there then no first principle at all?
