Vitae philosophorum

Diogenes Laertius

Diogenes Laertius. Hicks, R. D., editor. Cambridge, MA.: Harvard University Press; London: William Heinemann Ltd., 1925.

He was buried in the Academy, where he spent the greatest part of his life in philosophical study. And hence the school which he founded was called the Academic school. And all the students there joined in the funeral procession. The terms of his will were as follows:

These things have been left and devised by

V1_315
Plato: the estate in Iphistiadae, bounded on the north by the road from the temple at Cephisia, on the south by the temple of Heracles in Iphistiadae, on the east by the property of Archestratus of Phrearrhi, on the west by that of Philippus of Chollidae: this it shall be unlawful for anyone to sell or alienate, but it shall be the property of the boy Adeimantus to all intents and purposes:

the estate in Eiresidae which I bought of Callimachus, bounded on the north by the property of Eurymedon of Myrrhinus, on the south by the property of Demostratus of Xypete, on the east by that of Eurymedon of Myrrhinus, and on the west by the Cephisus; three minae of silver; a silver vessel weighing 165 drachmas; a cup weighing 45 drachmas; a gold signet-ring and earring together weighing four drachmas and three obols. Euclides the lapidary owes me three minae. I enfranchise Artemis. I leave four household servants, Tychon, Bictas, Apollonides and Dionysius.

Household furniture, as set down in the inventory of which Demetrius has the duplicate. I owe no one anything. My executors are Leosthenes, Speusippus, Demetrius, Hegias, Eurymedon, Callimachus and Thrasippus.

Such were the terms of his will. The following epitaphs were inscribed upon his tomb[*](Anth. Pal. vii. 60.):

Here lies the god-like man Aristocles, eminent among men for temperance and the justice of his character. And he, if ever anyone, had the fullest meed of praise for wisdom, and was too great for envy.

Next[*](Anth. Pal. vii. 61.):

Earth in her bosom here hides Plato’s body, but his soul hath its immortal station with the blest, Ariston’s son,
V1_317
whom every good man, even if he dwell afar off, honours because he discerned the divine life.
And a third of later date[*](Anth. Pal. vii. 62.):
  1. A. Eagle, why fly you o’er this tomb? Say, is your gaze fixed upon the starry house of one of the immortals?
  2. B. I am the image of the soul of Plato, which has soared to Olympus, while his earth-born body rests in Attic soil.

There is also an epitaph of my own which runs thus[*](Anth. Pal. vii. 108.):

If Phoebus did not cause Plato to be born in Greece, how came it that he healed the minds of men by letters? As the god’s son Asclepius is a healer of the body, so is Plato of the immortal soul.
And another on the manner of his death[*](Anth. Pal. vii. 109.):
Phoebus gave to mortals Asclepius and Plato, the one to save their souls, the other to save their bodies. From a wedding banquet he has passed to that city which he had founded for himself and planted in the sky.
Such then are his epitaphs.

His disciples were Speusippus of Athens, Xenocrates of Chalcedon, Aristotle of Stagira, Philippus of Opus, Hestiaeus of Perinthus, Dion of Syracuse, Amyclus of Heraclea, Erastus and Coriscus of Scepsus, Timolaus of Cyzicus, Euaeon of Lampsacus, Python and Heraclides of Aenus, Hippothales and Callippus of Athens, Demetrius of Amphipolis, Heraclides of Pontus, and many others, among them two women, Lastheneia of Mantinea and Axiothea of Phlius, who is reported by Dicaearchus to have worn men’s clothes. Some say that Theophrastus too attended his lectures. Chamaeleon adds Hyperides

V1_319
the orator and Lycurgus,

and in this Polemo agrees. Sabinus makes Demosthenes his pupil, quoting, in the fourth book of his Materials for Criticism, Mnesistratus of Thasos as his authority. And it is not improbable.[*](Here begins the first of three appendices, being an introduction to the study of the Platonic writings (47-66). Freudenthal, in Hell. Stud. iii., has shown that the extant fragment of the Πρόλογος of Albinus is similar and probably derived from the same source. Albinus lived in the second century a.d., for in 151-2 Galen was his pupil in Smyrna. The reader will note the careful style of the preface with its avoidance of hiatus. In x. 29 is a similar personal appeal to the reader.)

Now, as you are an enthusiastic Platonist, and rightly so, and as you eagerly seek out that philosopher’s doctrines in preference to all others, I have thought it necessary to give some account of the true nature of his discourses, the arrangement of the dialogues, and the method of his inductive procedure, as far as possible in an elementary manner and in main outline, in order that the facts I have collected respecting his life may not suffer by the omission of his doctrines. For, in the words of the proverb, it would be taking owls to Athens, were I to give you of all people the full particulars.

They say that Zeno the Eleatic was the first to write dialogues. But, according to Favorinus in his Memorabilia, Aristotle in the first book of his dialogue On Poets asserts that it was Alexamenus of Styra or Teos. In my opinion Plato, who brought this form of writing to perfection, ought to be adjudged the prize for its invention as well as for its embellishment. A dialogue is a discourse consisting of question and answer on some philosophical or political subject, with due regard to the characters of the persons introduced and the choice of diction. Dialectic is the art of discourse by which we either refute or establish some proposition by means of question and answer on the part of the interlocutors.

V1_321

Of the Platonic dialogues there are two most general types, the one adapted for instruction and the other for inquiry. And the former is further divided into two types, the theoretical and the practical. And of these the theoretical is divided into the physical and logical, and the practical into the ethical and political. The dialogue of inquiry also has two main divisions, the one of which aims at training the mind and the other at victory in controversy. Again, the part which aims at training the mind has two subdivisions, the one akin to the midwife’s art, the other merely tentative. And that suited to controversy is also subdivided into one part which raises critical objections, and another which is subversive of the main position.

I am not unaware that there are other ways in which certain writers classify the dialogues. For some dialogues they call dramatic, others narrative, and others again a mixture of the two. But the terms they employ in their classification of the dialogues are better suited to the stage than to philosophy. Physics is represented by the Timaeus, logic by the Statesman, Cratylus, Parmenides and Sophist, ethics by the Apology, Crito, Phaedo, Phaedrus and Symposium, as well as by the Menexenus, Clitophon, the Epistles, Philebus, Hipparchus and the Rivals, and lastly politics by the Republic, the Laws, Minos, Epinomis, and the dialogue concerning Atlantis.[*](i.e.Critias.)

To the class of mental obstetrics belong the two Alcibiades, Theages, Lysis and Laches, while the Euthyphro, Meno, Io, Charmides and Theaetetus illustrate the tentative method. In the Protagoras is seen the method of critical objections; in the

V1_323
Euthydemus, Gorgias, and the two dialogues entitled Hippias that of subversive argument. So much then for dialogue, its definition and varieties.

Again, as there is great division of opinion between those who affirm and those who deny that Plato was a dogmatist, let me proceed to deal with this further question. To be a dogmatist in philosophy is to lay down positive dogmas, just as to be a legislator is to lay down laws. Further, under dogma two things are included, the thing opined and the opinion itself.

Of these the former is a proposition, the latter a conception. Now where he has a firm grasp Plato expounds his own view and refutes the false one, but, if the subject is obscure, he suspends judgement. His own views are expounded by four persons, Socrates, Timaeus, the Athenian Stranger,[*](In the Laws.) the Eleatic Stranger.[*](In the Sophist and the Statesman.) These strangers are not, as some hold, Plato and Parmenides, but imaginary characters without names,[*](That the Eleatic Stranger is not Parmenides is decisively proved by Soph. 241 e.) for, even when Socrates and Timaeus are the speakers, it is Plato’s doctrines that are laid down. To illustrate the refutation of false opinions, he introduces Thrasymachus, Callicles, Polus, Gorgias, Protagoras, or again Hippias, Euthydemus and the like.

In constructing his proofs he makes most use of induction, not always in the same way, but under two forms. For induction is an argument which by means of certain true premisses properly infers a truth resembling them. And there are two kinds of induction, the one proceeding by way of contradiction, the other from agreement. In the kind which proceeds by contradiction the answer given to every question will necessarily be the contrary of the

V1_325
respondent’s position, e.g. My father is either other than or the same as your father. If then your father is other than my father, by being other than a father he will not be a father. But if he is the same as my father, then by being the same as my father he will be my father.

And again: If man is not an animal, he will be either a stick or a stone. But he is not a stick or a stone; for he is animate and self-moved. Therefore he is an animal. But if he is an animal, and if a dog or an ox is also an animal, then man by being an animal will be a dog and an ox as well. This is the kind of induction which proceeds by contradiction and dispute, and Plato used it, not for laying down positive doctrines but for refutation. The other kind of induction by agreement appears in two forms, the one proving the particular conclusion under discussion from a particular, the other proceeding by way of the universal [by means of particular facts]. The former is suited to rhetoric, the latter to dialectic. For instance, under the first form the question is raised, Did so-and-so commit a murder? The proof is that he was found at the time with stains of blood on him.

This is the rhetorical form of induction, since rhetoric also is concerned with particular facts and not with universals. It does not inquire about justice in the abstract, but about particular cases of justice. The other kind, where the general proposition is first established by means of particular facts, is the induction of dialectic. For instance, the question put is whether the soul is immortal, and whether the living come back from the dead. And this is proved in the dialogue On the Soul by means of a certain general proposition, that opposites proceed

V1_327
from opposites. And the general proposition itself is established by means of certain propositions which are particular, as that sleep comes from waking and vice versa, the greater from the less and vice versa. This is the form which he used to establish his own views.

But, just as long ago in tragedy the chorus was the only actor, and afterwards, in order to give the chorus breathing space, Thespis devised a single actor, Aeschylus a second, Sophocles a third, and thus tragedy was completed, so too with philosophy: in early times it discoursed on one subject only, namely physics, then Socrates added the second subject, ethics, and Plato the third, dialectics, and so brought philosophy to perfection. Thrasylus says that he published his dialogues in tetralogies, like those of the tragic poets. Thus they contended with four plays at the Dionysia, the Lenaea, the Panathenaea and the festival of Chytri.[*](Pots.) Of the four plays the last was a satiric drama; and the four together were called a tetralogy.

Now, says Thrasylus, the genuine dialogues are fifty-six in all, if the Republic be divided into ten and the Laws into twelve. Favorinus, however, in the second book of his Miscellaneous History declares that nearly the whole of the Republic is to be found in a work of Protagoras entitled Controversies.[*](From iii. 37 we infer that Favorinus drew upon Aristoxenus for this wildly improbable assertion.) This gives nine tetralogies, if the Republic takes the place of one single work and the Laws of another. His first tetralogy has a common plan underlying it, for he wishes to describe what the life of the philosopher

V1_329
will be. To each of the works Thrasylus affixes a double title, the one taken from the name of the interlocutor, the other from the subject.

This tetralogy, then, which is the first, begins with the Euthyphro or On Holiness, a tentative dialogue; the Apology of Socrates, an ethical dialogue, comes second; the third is Crito or On what is to be done, ethical; the fourth Phaedo or On the Soul, also ethical. The second tetralogy begins with Cratylus or On Correctness of Names, a logical dialogue, which is followed by Theaetetus or On Knowledge, tentative, the Sophist or On Being, a logical dialogue, the Statesman or On Monarchy, also logical. The third tetralogy includes, first, Parmenides or On Ideas, which is logical, next Philebus or On Pleasure, an ethical dialogue, the Banquet or On the Good, ethical, Phaedrus or On Love, also ethical.

The fourth tetralogy starts with Alcibiades or On the Nature of Man, an obstetric dialogue; this is followed by the second Alcibiades or On Prayer, also obstetric; then comes Hipparchus or The Lover of Gain, which is ethical, and The Rivals or On Philosophy, also ethical. The fifth tetralogy includes, first, Theages or On Philosophy, an obstetric dialogue, then Charmides or On Temperance, which is tentative, Laches or On Courage, obstetric, and Lysis or On Friendship, also obstetric. The sixth tetralogy starts with Euthydemus or The Eristic, a refutative dialogue, which is followed by Protagoras or Sophists, critical, Gorgias or On Rhetoric, refutative, and Meno or On Virtue, which is tentative.

The seventh tetralogy contains, first, two dialogues entitled Hippias, the former On Beauty, the latter On Falsehood, both refutative; next Ion or On the Iliad, which is tentative,

V1_331
and Menexenus or The Funeral Oration, which is ethical. The eighth tetralogy starts with Clitophon or Introduction, which is ethical, and is followed by the Republic or On Justice, political, Timaeus or On Nature, a physical treatise, and Critias or Story of Atlantis, which is ethical. The ninth tetralogy starts with Minos or On Law, a political dialogue, which is followed by the Laws or On Legislation, also political, Epinomis or Nocturnal Council, or Philosopher, political, and lastly the Epistles, thirteen in number, which are ethical.
