BOOK X.. Epicurus 424

EPICURUS 424

PREFACE.

Diogenes, the author of the following work, was a native (as is generally believed) of Laërte, in Cilicia, from which circumstance he derived the cognomen of Laërtius. Little is known of him personally, nor is even the age in which he lived very clearly ascertained. But as Plutarch, Sextus Empiricus, and Saturninus are among the writers whom he quotes, he is generally believed to have lived near the end of the second century of our era: although some place him in the time of Alexander Severus, and others as late as Constantine. His work consists of ten books, variously called: The Lives of Philosophers, A History of Philosophy, and The Lives of Sophists. From internal evidence (iii. 47, 29), we learn that he wrote it for a noble lady (according to some, Arria; according to others, Julia, the Empress of Severus), who occupied herself with the study of philosophy, and especially of Plato.

Diogenes Laërtius divides the philosophy of the Greeks into the Ionic, beginning with Anaximander, and ending with Theophrastus (in which class, he includes the Socratic philosophy and all its various ramifications); and the Italian, beginning with Pythagoras, and ending with Epicurus, in which he includes the Eleatics, as also Heraclitus and the Sceptics. From the minute consideration which he devotes to Epicurus and his system, it has been supposed that he himself belonged to that school.

His work is the chief source of information we possess concerning the history of Greek philosophy, and is the foundation of nearly all the modern treatises on that subject; some of the most important of which are little more than translations or amplifications of it. It is valuable, as containing a copious collection of anecdotes illustrative of the life and manners of the Greeks; but he has not always been very careful in his selection, and in some parts there is a confusion in his statements that makes them scarcely intelligible. These faults have led some critics to consider the work as it now exists merely a mutilated abridgment of the original. Breslæus, who in the thirteenth century, wrote a Treatise on the Lives and Manners of the Philosophers, quotes many anecdotes and sayings, which seem to be derived from Diogenes, but which are not to be found in our present text; whence Schneider concludes that he had a very different and far more complete copy than has come down to us.

The text used in the following translation is chiefly that of Huebner, as published at Leipsic, A.D. 1828.

LIVES AND OPINIONS OF EMINENT PHILOSOPHERS.

BOOK I.. Introduction.

INTRODUCTION.

I. Some say that the study of philosophy originated with the barbarians. In that among the Persians there existed the Magi, and among the Babylonians or Assyrians the Chaldæi, among the Indians the Gymnosophistæ, and among the Celts and Gauls men who were called Druids and Semnothei, as Aristotle relates in his book on Magic, and Sotion in the twenty-third book of his Succession of Philosophers. Besides those men there were the Phœnician Ochus, the Thracian Zamolxis, and the Libyan Atlas. For the Egyptians say that Vulcan was the son of Nilus, and that he was the author of philosophy, in which those who were especially eminent were called his priests and prophets.

II. From his age to that of Alexander, king of the Macedonians were forty-eight thousand eight hundred and sixty-three years, and during this time there were three hundred and seventy-three eclipses of the sun, and eight hundred and thirty-two eclipses of the moon.

Again, from the time of the Magi, the first of whom was Zoroaster the Persian, to that of the fall of Troy, Hermodorus the Platonic philosopher, in his treatise on Mathematics, calculates that fifteen thousand years elapsed. But Xanthus the Lydian says that the passage of the Hellespont by Xerxes took place six thousand years after the time of Zoroaster, and that after him there was a regular succession of Magi under the names of Ostanes and Astrampsychos and Gobryas and Pazatas, until the destruction of the Persian empire by Alexander.

III. But those who say this, ignorantly impute to the barbarians the merits of the Greeks, from whom not only all philosophy, but even the whole human race in reality originated. For Musæus was born among the Athenians, and Linus among the Thebans; and they say that the former, who was the son of Eumolpus, was the first person who taught the system of the genealogy of the gods, and who invented the spheres; and that he taught that all things originated in one thing, and when dissolved returned to that same thing; and that he died at Phalerum, and that this epitaph was inscribed on his tomb:—

Phalerum’s soil beneath this tomb contains Musæus dead, Eumolpus’ darling son.

And it is from the father of Musæus that the family called Eumolpidæ among the Athenians derive their name. They say too that Linus was the son of Mercury and the Muse Urania; and that he invented a system of Cosmogony, and of the motions of the sun and moon, and of the generation of animals and fruits; and the following is the beginning of his poem,

There was a time when all the present world Uprose at once.

From which Anaxagoras derived his theory, when he said that all things had been produced at the same time, and that then intellect had come and arranged them all in order.

They say, moreover, that Linus died in Eubœa, having been shot with an arrow by Apollo, and that this epitaph was set over him:—

The Theban Linus sleeps beneath this ground, Urania’s son with fairest garlands crown’d.

IV. And thus did philosophy arise among the Greeks, and indeed its very name shows that it has no connection with the barbarians. But those who attribute its origin to them, introduce Orpheus the Thracian, and say that he was a philosopher, and the most ancient one of all. But if one ought to call a man who has said such things about the gods as he has said, a philosopher, I do not know what name one ought to give to him who has not scrupled to attribute all sorts of human feelings to the gods, and even such discreditable actions as are but rarely spoken of among men; and tradition relates that he was murdered by women; but there is an inscription at Dium in Macedonia, saying that he was killed by lightning, and it runs thus:—

Here the bard buried by the Muses lies, The Thracian Orpheus of the golden lyre; Whom mighty Jove, the Sovereign of the skies, Removed from earth by his dread lightn’ng’s fire.

V. But they who say that philosophy had its rise among the barbarians, give also an account of the different systems prevailing among the various tribes. And they say that the Gymnosophists and the Druids philosophize, delivering their apophthegms in enigmatical language, bidding men worship the gods and do no evil, and practise manly virtue.

VI. Accordingly Clitarchus, in his twelfth book, says that the Gymnosophists despise death, and that the Chaldæans study astronomy and the science of soothsaying—that the Magi occupy themselves about the service to be paid to the gods, and about sacrifices and prayers, as if they were the only people to whom the deities listen: and that they deliver accounts of the existence and generation of the gods, saying that they are fire, and earth, and water; and they condemn the use of images, and above all things do they condemn those who say that the gods are male and female; they speak much of justice, and think it impious to destroy the bodies of the dead by fire; they allow men to marry their mothers or their daughters, as Sotion tells us in his twenty-third book; they study the arts of soothsaying and divination, and assert that the gods reveal their will to them by those sciences. They teach also that the air is full of phantoms, which, by emanation and a sort of evaporation, glide into the sight of those who have a clear perception; they forbid any extravagance of ornament, and the use of gold; their garments are white, their beds are made of leaves, and vegetables are their food, with cheese and coarse bread; they use a rush for a staff, the top of which they run into the cheese, and so taking up a piece of it they eat it. Of all kinds of magical divination they are ignorant, as Aristotle asserts in his book on Magic, and Dinon in the fifth book of his Histories. And this writer says, that the name of Zoroaster being interpreted means, a sacrifice to the stars; and Hermodorus makes the same statement. But Aristotle, in the first book of his Treatise on Philosophy, says, that the Magi are more ancient than the Egyptians; and that according to them there are two principles, a good demon and an evil demon, and that the name of the one is Jupiter or Oromasdes, and that of the other Pluto or Arimanius. And Hermippus gives the same account in the first book of his History of the Magi; and so does Eudoxus in his Period; and so does Theopompus in the eighth book of his History of the Affairs of Philip; and this last writer tells us also, that according to the Magi men will have a resurrection and be immortal, and that what exists now will exist hereafter under its own present name; and Eudemus of Rhodes coincides in this statement. But Hecatæus says, that according to their doctrines the gods also are beings who have been born. But Clearchus the Solensian, in his Treatise on Education says, that the Gymnosophists are descendants of the Magi; and some say that the Jews also are derived from them. Moreover, those who have written on the subject of the Magi condemn Herodotus; for they say that Xerxes would never have shot arrows against the sun, or have put fetters on the sea, as both sun and sea have been handed down by the Magi as gods, but that it was quite consistent for Xerxes to destroy the images of the gods.
