There is also an epitaph of my own which runs thus: ⁵³

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: ⁵⁴

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 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. ⁵⁵

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.

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. ⁵⁶ 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 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, ⁵⁷ the Eleatic Stranger. ⁵⁸ These strangers are not, as some hold, Plato and Parmenides, but imaginary characters without names, ⁵⁹ 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 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 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. ⁶⁰ 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. ⁶¹ 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 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, 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. In these epistles his heading was "Welfare," as that of Epicurus was "A Good Life," and that of Cleon "All Joy." They comprise: one to Aristodemus, two to Archytas, four to Dionysius, one to Hermias, Erastus and Coriscus, one each to Leodamas, Dion and Perdiccas, and two to Dion's friends. This is the division adopted by Thrasylus and some others.

Some, including Aristophanes the grammarian, arrange the dialogues arbitrarily in trilogies. In the first trilogy they place the Republic, Timaeus and Critias; in the second the Sophist, the Statesman and Cratylus; in the third the Laws, Minos and Epinomis; in the fourth Theaetetus, Euthyphro and the Apology; in the fifth Crito, Phaedo and the Epistles. The rest follow as separate compositions in no regular order. Some critics, as has already been stated, put the Republic first, while others start with the greater Alcibiades, and others again with the Theages; some begin with the Euthyphro, others with the Clitophon; some with the Timaeus, others with the Phaedrus; others again with the Theaetetus, while many begin with the Apology. The following dialogues are acknowledged to be spurious: the Midon or Horse-breeder, the Eryxias or Erasistratus, the Alcyon, the Acephali or Sisyphus, the Axiochus, the Phaeacians, the Demodocus, the Chelidon, the Seventh Day, the Epimenides. Of these the Alcyon ⁶² is thought to be the work of a certain Leon, according to Favorinus in the fifth book of his Memorabilia.

Plato has employed a variety of terms in order to make his system less intelligible to the ignorant. But in a special sense he considers wisdom to be the science of those things which are objects of thought and really existent, the science which, he says, is concerned with God and the soul as separate from the body. And especially by wisdom he means philosophy, which is a yearning for divine wisdom. And in a general sense all experience is also termed by him wisdom, e.g. when he calls a craftsman wise. And he applies the same terms with very different meanings. For instance, the word φαῦλος (slight, plain) is employed by him ⁶³ in the sense of ἁπλοῦς (simple, honest), just as it is applied to Heracles in the Licymnius of Euripides in the following passage: ⁶⁴

Plain (φαῦλος), unaccomplished, staunch to do great deeds, unversed in talk, with all his store of wisdom curtailed to action.

But sometimes Plato uses this same word (φαῦλος） to mean what is bad, and at other times for what is small or petty. Again, he often uses different terms to express the same thing. For instance, he calls the Idea form (εἶδος), genus (γένος), archetype (παράδειγμα), principle (;ἀρχ&#x03ae) and cause (αἴτιον). He also uses contrary expressions for the same thing. Thus he calls the sensible thing both existent and non-existent, existent inasmuch as it comes into being, non-existent because it is continually changing. And he says the Idea is neither in motion nor at rest; that it is uniformly the same and yet both one and many. And it is his habit to do this in many more instances.

The right interpretation of his dialogues includes three things: first, the meaning of every statement must be explained; next, its purpose, whether it is made for a primary reason or by way of illustration, and whether to establish his own doctrines or to refute his interlocutor; in the third place it remains to examine its truth.

And since certain critical marks are affixed to his works let us now say a word about these. The cross × is taken to indicate peculiar expressions and figures of speech, and generally any idiom of Platonic usage; the diple ⁶⁵ (>) calls attention to doctrines and opinions characteristic of Plato; the dotted cross (⨰) denotes select passages and beauties of style; the dotted diple (⋗) editors' corrections of the text; the dotted obelus (÷) passages suspected without reason; the dotted antisigma (Ꜿ) repetitions and proposals for transpositions; the ceraunium the philosophical school; the asterisk (∗) an agreement of doctrine; the obelus (−) a spurious passage. So much for the critical marks and his writings in general. As Antigonus of Carystus says in his Life of Zeno, when the writings were first edited with critical marks, their possessors charged a certain fee to anyone who wished to consult them.

The doctrines he approved are these. ⁶⁶ He held that the soul is immortal, that by transmigration it puts on many bodies, ⁶⁷ and that it has a numerical first principle, whereas the first principle of the body is geometrical; ⁶⁸ and he defined soul as the idea of vital breath diffused in all directions. He held that it is self-moved and tripartite, the rational part of it having its seat in the head, the passionate part about the heart, while the appetitive is placed in the region of the navel and the liver. ⁶⁹

And from the centre outwards it encloses the body on all sides in a circle, and is compounded of elements, and, being divided at harmonic intervals, it forms two circles which touch one another twice; and the interior circle, being slit six times over, makes seven circles in all. And this interior circle moves by way of the diagonal to the left, and the other by way of the side to the right. Hence also the one is supreme, being a single circle, for the other interior circle was divided; the former is the circle of the Same, the latter that of the Other, whereby he means that the motion of the soul is the motion of the universe together with the revolutions of the planets. ⁷⁰

And the division from the centre to the circumference which is adjusted in harmony with the soul being thus determined, the soul knows that which is, and adjusts it proportionately because she has the elements proportionately disposed in herself. And when the circle of the Other revolves aright, the result is opinion; but from the regular motion of the circle of the Same comes knowledge. He set forth two universal principles, God and matter, and he calls God mind and cause; he held that matter is devoid of form and unlimited, and that composite things arise out of it; ⁷¹ and that it was once in disorderly motion but, inasmuch as God preferred order to disorder, was by him brought together in one place. ⁷² This substance, he says, is converted into the four elements, fire, water, air, earth, of which the world itself and all that therein is are formed. Earth alone of these elements is not subject to change, the assumed cause being the peculiarity of its constituent triangles. For he thinks that in all the other elements the figures employed are homogeneous, the scalene triangle out of which they are all put together being one and the same, whereas for earth a triangle of peculiar shape is employed; the element of fire is a pyramid, of air an octahedron, of water an icosahedron, of earth a cube. Hence earth is not transmuted into the other three elements, nor these three into earth.

But the elements are not separated each into its own region of the universe, because the revolution unites their minute particles, compressing and forcing them together into the centre, at the same time as it separates the larger masses. Hence as they change their shapes, so also do they change the regions which they occupy. ⁷³

And there is one created universe, ⁷⁴ seeing that it is perceptible to sense, which has been made by God. And it is animate because that which is animate is better than that which is inanimate. ⁷⁵ And this piece of workmanship is assumed to come from a cause supremely good. ⁷⁶ It was made one and not unlimited because the pattern from which he made it was one. And it is spherical because such is the shape of its maker. For that maker contains the other living things, and this universe the shapes of them all. ⁷⁷ It is smooth and has no organ all round because it has no need of organs. Moreover, the universe remains imperishable because it is not dissolved into the Deity. ⁷⁸ And the creation as a whole is caused by God, because it is the nature of the good to be beneficent, ⁷⁹ and the creation of the universe has the highest good for its cause. For the most beautiful of created things is due to the best of intelligible causes; ⁸⁰ so that, as God is of this nature, and the universe resembles the best in its perfect beauty, it will not be in the likeness of anything created, but only of God.

The universe is composed of fire, water, air and earth; of fire in order to be visible; of earth in order to be solid; of water and air in order to be proportional. ⁸¹ For the powers represented by solids are connected by two mean proportionals in a way to secure the complete unity of the whole. And the universe was made of all the elements in order to be complete and indestructible.

Time was created as an image of eternity. And while the latter remains for ever at rest, time consists in the motion of the universe. For night and day and month and the like are all parts of time; for which reason, apart from the nature of the universe, time has no existence. But so soon as the universe is fashioned time exists. ⁸²

And the sun and moon and planets were created as means to the creation of time. And God kindled the light of the sun in order that the number of the seasons might be definite and in order that animals might possess number. The moon is in the circle immediately above the earth, and the sun in that which is next beyond that, and in the circles above come the planets. Further, the universe is an animate being, for it is bound fast in animate movement. ⁸³ And in order that the universe which had been created in the likeness of the intelligible living creature might be rendered complete, the nature of all other animals was created. Since then its pattern possesses them, the universe also ought to have them. And thus it contains gods for the most part of a fiery nature; of the rest there are three kinds, winged, aquatic and terrestrial. ⁸⁴ And of all the gods in heaven the earth is the oldest. And it was fashioned to make night and day. And being at the centre it moves round the centre. ⁸⁵ And since there are two causes, it must be affirmed, he says, that some things are due to reason and others have a necessary cause, ⁸⁶ the latter being air, fire, earth and water, which are not exactly elements but rather recipients of form. ⁸⁷ They are composed of triangles, and are resolved into triangles. The scalene triangle and the isosceles triangle are their constituent elements. ⁸⁸

The principles, then, and causes assumed are the two above mentioned, of which God and matter are the exemplar. Matter is of necessity formless like the other recipients of form. Of all these there is a necessary cause. For it somehow or other receives the ideas and so generates substances, and it moves because its power is not uniform, and, being in motion, it in turn sets in motion those things which are generated from it. And these were at first in irrational and irregular motion, but after they began to frame the universe, under the conditions possible they were made by God symmetrical and regular. For the two causes existed even before the world was made, as well as becoming in the third place, but they were not distinct, merely traces of them being found, and in disorder. When the world was made, they too acquired order. ⁸⁹ And out of all the bodies there are the universe was fashioned. He holds God, like the soul, to be incorporeal. For only thus is he exempt from change and decay. As already stated, he assumes the Ideas to be causes and principles whereby the world of natural objects is what it is.

On good and evil he would discourse to this effect. He maintained that the end to aim at is assimilation to God, that virtue is in itself sufficient for happiness, but that it needs in addition, as instruments for use, first, bodily advantages like health and strength, sound senses and the like, and, secondly, external advantages such as wealth, good birth and reputation. But the wise man will be no less happy even if he be without these things. Again, he will take part in public affairs, will marry, and will refrain from breaking the laws which have been made. And as far as circumstances allow he will legislate for his own country, unless in the extreme corruption of the people he sees that the state of affairs completely justifies his abstention. He thinks that the gods take note of human life ⁹⁰ and that there are superhuman beings. ⁹¹ He was the first to define the notion of good as that which is bound up with whatever is praiseworthy and rational and useful and proper and becoming. And all these are bound up with that which is consistent and in accord with nature.

He also discoursed on the propriety of names, and indeed he was the first to frame a science for rightly asking and answering questions, having employed it himself to excess. And in the dialogues he conceived righteousness to be the law of God because it is stronger to incite men to do righteous acts, that malefactors may not be punished after death also. Hence to some he appeared too fond of myths. These narratives he intermingles with his works in order to deter men from wickedness, by reminding them how little they know of what awaits them ⁹² after death. Such, then, are the doctrines he approved.

He used also to divide things, according to Aristotle, in the following manner. ⁹³ Goods are in the mind or in the body, or external. For example, justice, prudence, courage, temperance and such like are in the mind; beauty, a good constitution, health and strength in the body; while friends, the welfare of one's country and riches are amongst external things.

Thus there are three kinds of goods: goods of the mind, goods of the body and external goods. There are three species of friendship: one species is natural, another social, and another hospitable. By natural friendship we mean the affection which parents have for their offspring and kinsmen for each other. And other animals besides man have inherited this form.

By the social form of friendship we mean that which arises from intimacy and has nothing to do with kinship; for instance, that of Pylades for Orestes. The friendship of hospitality is that which is extended to strangers owing to an introduction or letters of recommendation. Thus friendship is either natural or social or hospitable. Some add a fourth species, that of love.

There are five forms of civil government: one form is democratic, another aristocratic, a third oligarchic, a fourth monarchic, a fifth that of a tyrant. The democratic form is that in which the people has control and chooses at its own pleasure both magistrates and laws. The aristocratic form is that in which the rulers are neither the rich nor the poor nor the nobles, but the state is under the guidance of the best. Oligarchy is that form in which there is a property-qualification for the holding of office; for the rich are fewer than the poor. Monarchy is either regulated by law or hereditary. At Carthage the kingship is regulated by law, the office being put up for sale. ⁹⁴ But the monarchy in Lacedaemon and in Macedonia is hereditary, for they select the king from a certain family. A tyranny is that form in which the citizens are ruled either through fraud or force by an individual. Thus civil government is either democratic, aristocratic, oligarchic, or a monarchy or a tyranny.

There are three species of justice. One is concerned with gods, another with men, and the third with the departed. For those who sacrifice according to the laws and take care of the temples are obviously pious towards the gods. Those again who repay loans and restore what they have received upon trust act justly towards men. Lastly, those who take care of tombs are obviously just towards the departed. Thus one species of justice relates to the gods, another to men, while a third species is concerned with the departed.

There are three species of knowledge or science, one practical, another productive, and a third theoretical. For architecture and shipbuilding are productive arts, since the work produced by them can be seen. Politics and flute-playing, harp-playing and similar arts are practical. For nothing visible is produced by them; yet they do or perform something. In the one case the artist plays the flute or the harp, in the other the politician takes part in politics. Geometry and harmonics and astronomy are theoretical sciences. For they neither perform nor produce anything. But the geometer considers how lines are related to each other, the student of harmony investigates sounds, the astronomer stars and the universe. Thus some sciences are theoretical, others are practical, and others are productive.

There are five species of medicine : the first is pharmacy, the second is surgery, the third deals with diet and regimen, the fourth with diagnosis, the fifth with remedies. Pharmacy cures sickness by drugs, surgery heals by the use of knife and cautery, the species concerned with diet prescribes a regimen for the removal of disease, that concerned with diagnosis proceeds by determining the nature of the ailment, that concerned with remedies by prescribing for the immediate removal of the pain. The species of medicine, then, are pharmacy, surgery, diet and regimen, diagnosis, prescription of remedies.

There are two divisions of law, the one written and the other unwritten. Written law is that under which we live in different cities, but that which has arisen out of custom is called unwritten law; for instance, not to appear in the market-place undressed or in women's attire. There is no statute forbidding this, but nevertheless we abstain from such conduct because it is prohibited by an unwritten law. Thus law is either written or unwritten.

There are five kinds of speech, of which one is that which politicians employ in the assemblies; this is called political speech. The second division is that which the rhetors employ in written compositions, whether composed for display or praise or blame, or for accusation. Hence this division is termed rhetorical. The third division of speech is that of private persons conversing with one another; this is called the mode of speech of ordinary life. Another division of speech is the language of those who converse by means of short questions and answers; this kind is called dialectical. The fifth division is the speech of craftsmen conversing about their own subjects; this is called technical language. Thus speech is either political, or rhetorical, or that of ordinary conversation, or dialectical, or technical.

Music has three divisions. One employs the mouth alone, like singing. The second employs both the mouth and the hands, as is the case with the harper singing to his own accompaniment. The third division employs the hands alone; for instance, the music of the harp. Thus music employs either the mouth alone, or the mouth and the hands, or the hands alone.

Nobility has four divisions. First, when the ancestors are gentle and handsome and also just, their descendants are said to be noble. Secondly, when the ancestors have been princes or magistrates, their descendants are said to be noble. The third kind arises when the ancestors have been illustrious; for instance, through having held military command or through success in the national games. For then we call the descendants noble. The last division includes the man who is himself of a generous and high-minded spirit. He too is said to be noble. And this indeed is the highest form of nobility. Thus, of nobility, one kind depends on excellent ancestors, another on princely ancestors, a third on illustrious ancestors, while the fourth is due to the individual's own beauty and worth.

Beauty has three divisions. The first is the object of praise, as of form fair to see. Another is serviceable; thus an instrument, a house and the like are beautiful for use. Other things again which relate to customs and pursuits and the like are beautiful because beneficial. Of beauty, then, one kind is matter for praise, another is for use, and another for the benefit it procures.

The soul has three divisions. One part of it is rational, another appetitive, and a third irascible. Of these the rational part is the cause of purpose, reflection, understanding and the like. The appetitive part of the soul is the cause of desire of eating, sexual indulgence and the like, while the irascible part is the cause of courage, of pleasure and pain, and of anger. Thus one part of the soul is rational, another appetitive, and a third irascible.

Of perfect virtue there are four species: prudence, justice, bravery and temperance. Of these prudence is the cause of right conduct, justice of just dealing in partnerships and commercial transactions. Bravery is the cause which makes a man not give way but stand his ground in alarms and perils. Temperance causes mastery over desires, so that we are never enslaved by any pleasure, but lead an orderly life. Thus virtue includes first prudence, next justice, thirdly bravery, and lastly temperance.

Rule has five divisions, one that which is according to law, another according to nature, another according to custom, a fourth by birth, a fifth by force. Now the magistrates in cities when elected by their fellow-citizens rule according to law. The natural rulers are the males, not only among men, but also among the other animals; for the males everywhere exert wide-reaching rule over the females. Rule according to custom is such authority as attendants exercise over children and teachers over their pupils. Hereditary rule is exemplified by that of the Lacedaemonian kings, for the office of king is confined to a certain family. And the same system is in force for the kingdom of Macedonia; for there too the office of king goes by birth. Others have acquired power by force or fraud, and govern the citizens against their will; this kind of rule is called forcible. Thus rule is either by law, or by nature, or by custom, or by birth, or by force.

There are six kinds of rhetoric. For when the speakers urge war or alliance with a neighbouring state, that species of rhetoric is called persuasion. But when they speak against making war or alliance, and urge their hearers to remain at peace, this kind of rhetoric is called dissuasion. A third kind is employed when a speaker asserts that he is wronged by some one whom he makes out to have caused him much mischief; accusation is the name applied to the kind here defined. The fourth kind of rhetoric is termed defence; here the speaker shows that he has done no wrong and that his conduct is in no respect abnormal; defence is the term applied in such a case. A fifth kind of rhetoric is employed when a speaker speaks well of some one and proves him to be worthy and honourable; encomium is the name given to this kind. A sixth kind is that employed when the speaker shows some one to be unworthy; the name given to this is invective. Under rhetoric, then, are included encomium, invective, persuasion, dissuasion, accusation and defence.

Successful speaking has four divisions. The first consists in speaking to the purpose, the next to the requisite length, the third before the proper audience, and the fourth at the proper moment. The things to the purpose are those which are likely to be expedient for speaker and hearer. The requisite length is that which is neither more nor less than enough. To speak to the proper audience means this: in addressing persons older than yourself, the discourse must be made suitable to the audience as being elderly men; whereas in addressing juniors the discourse must be suitable to young men. The proper time of speaking is neither too soon nor too late; otherwise you will miss the mark and not speak with success.

Of conferring benefits there are four divisions. For it takes place either by pecuniary aid or by personal service, by means of knowledge or of speech. Pecuniary aid is given when one assists a man in need, so that he is relieved from all anxiety on the score of money. Personal service is given when men come up to those who are being beaten and rescue them. Those who train or heal, or who teach something valuable, confer benefit by means of knowledge. But when men enter a law-court and one appears as advocate for another and delivers an effective speech on his behalf, he is benefiting him by speech. Thus benefits are conferred by means either of money or of personal service, or of knowledge, or of speech.

There are four ways in which things are completed and brought to an end. The first is by legal enactment, when a decree is passed and this decree is confirmed by law. The second is in the course of nature, as the day, the year and the seasons are completed. The third is by the rules of art, say the builder's art, for so a house is completed; and so it is with shipbuilding, whereby vessels are completed. Fourthly, matters are brought to an end by chance or accident, when they turn out otherwise than is expected. Thus the completion of things is due either to law, or to nature, or to art, or to chance.

Of power or ability there are four divisions. First, whatever we can do with the mind, namely calculate or anticipate; next, whatever we can effect with the body, for instance, marching, giving, taking and the like. Thirdly, whatever we can do by a multitude of soldiers or a plentiful supply of money; hence a king is said to have great power. The fourth division of power or influence is doing, or being done by, well or ill; thus we can become ill or be educated, be restored to health and the like. Power, then, is either in the mind, or the body, or in armies and resources, or in acting and being acted upon.

Philanthropy is of three kinds. One is by way of salutations, as when certain people address every one they meet and, stretching out their hand, give him a hearty greeting; another mode is seen when one is given to assisting every one in distress; another mode of philanthropy is that which makes certain people fond of giving dinners. Thus philanthropy is shown either by a courteous address, or by conferring benefits, or by hospitality and the promotion of social intercourse.

Welfare or happiness includes five parts. One part of it is good counsel, a second soundness of the senses and bodily health, a third success in one's undertakings, a fourth a reputation with one's fellow-men, a fifth ample means in money and in whatever else subserves the end of life. Now deliberating well is a result of education and of having experience of many things. Soundness of the senses depends upon the bodily organs: I mean, if one sees with his eyes, hears with his ears, and perceives with his nostrils and his mouth the appropriate objects, then such a condition is soundness of the senses. Success is attained when a man does what he aims at in the right way, as becomes a good man.

A man has a good reputation when he is well spoken of. A man has ample means when he is so equipped for the needs of life that he can afford to benefit his friends and discharge his public services with lavish display. If a man has all these things, he is completely happy. Thus of welfare or happiness one part is good counsel, another soundness of senses and bodily health, a third success, a fourth a good reputation, a fifth ample means.

There are three divisions of the arts and crafts. The first division consists of mining and forestry, which are productive arts. The second includes the smith's and carpenter's arts which transform material; for the smith makes weapons out of iron, and the carpenter transforms timber into flutes and lyres. The third division is that which uses what is thus made, as horsemanship employs bridles, the art of war employs weapons, and music flutes and the lyre. Thus of art there are three several species, those above-mentioned in the first, second and third place.

Good is divided into four kinds. One is the possessor of virtue, whom we affirm to be individually good. Another is virtue itself and justice; these we affirm to be good. A third includes such things as food, suitable exercises and drugs. The fourth kind which we affirm to be good includes the arts of flute-playing, acting and the like. Thus there are four kinds of good: the possession of virtue; virtue itself; thirdly, food and beneficial exercises; lastly, flute-playing, acting, and the poetic art. Whatever is is either evil or good or indifferent. We call that evil which is capable of invariably doing harm; for instance, bad judgement and folly and injustice and the like. The contraries of these things are good. But the things which can sometimes benefit and sometimes harm, such as walking and sitting and eating, or which can neither do any benefit nor harm at all, these are things indifferent, neither good nor evil. Thus all things whatever are either good, or evil, or neither good nor evil.

Good order in the state falls under three heads. First, if the laws are good, we say that there is good government. Secondly, if the citizens obey the established laws, we also call this good government. Thirdly, if, without the aid of laws, the people manage their affairs well under the guidance of customs and institutions, we call this again good government. Thus three forms of good government may exist, (1) when the laws are good, (2) when the existing laws are obeyed, (3) when the people live under salutary customs and institutions.

Disorder in a state has three forms. The first arises when the laws affecting citizens and strangers are alike bad, the second when the existing laws are not obeyed, and the third when there is no law at all. Thus the state is badly governed when the laws are bad or not obeyed, or lastly, when there is no law.

Contraries are divided into three species. For instance, we say that goods are contrary to evils, as justice to injustice, wisdom to folly, and the like. Again, evils are contrary to evils, prodigality is contrary to niggardliness, and to be unjustly tortured is the contrary of being justly tortured, and so with similar evils. Again, heavy is the contrary of light, quick of slow, black of white, and these pairs are contraries, while they are neither good nor evil. Thus, of contraries, some are opposed as goods to evils, others as evils to evils, and others, as things which are neither good nor evil, are opposed to one another.

There are three kinds of goods, those which can be exclusively possessed, those which can be shared with others, and those which simply exist. To the first division, namely, those which can be exclusively possessed, belong such things as justice and health. To the next belong all those which, though they cannot be exclusively possessed, can be shared with others. Thus we cannot possess the absolute good, but we can participate in it. The third division includes those goods the existence of which is necessary, though we can neither possess them exclusively nor participate in them. The mere existence of worth and justice is a good; and these things cannot be shared or had in exclusive possession, but must simply exist. Of goods, then, some are possessed exclusively, some shared, and others merely subsist.

Counsel is divided under three heads. One is taken from past time, one from the future, and the third from the present. That from past time consists of examples; for instance, what the Lacedaemonians suffered through trusting others. Counsel drawn from the present is to show, for instance, that the walls are weak, the men cowards, and the supplies running short. Counsel from the future is. for instance, to urge that we should not wrong the embassies by suspicions, lest the fair fame of Hellas be stained. Thus counsel is derived from the past, the present and the future.

Vocal sound falls into two divisions according as it is animate or inanimate. The voice of living things is animate sound; notes of instruments and noises are inanimate. And of the animate voice part is articulate, part inarticulate, that of men being articulate speech, that of the animals inarticulate. Thus vocal sound is either animate or inanimate.

Whatever exists is either divisible or indivisible. Of divisible things some are divisible into similar and others into dissimilar parts. Those things are indivisible which cannot be divided and are not compounded of elements, for example, the unit, the point and the musical note; whereas those which have constituent parts, for instance, syllables, concords in music, animals, water, gold, are divisible. If they are composed of similar parts, so that the whole does not differ from the part except in bulk, as water, gold and all that is fusible, and the like, then they are termed homogeneous. But whatever is composed of dissimilar parts, as a house and the like, is termed heterogeneous. Thus all things whatever are either divisible or indivisible, and of those which are divisible some are homogeneous, others heterogeneous in their parts.

Of existing things some are absolute and some are called relative. Things said to exist absolutely are those which need nothing else to explain them, as man, horse, and all other animals. For none of these gains by explanation. To those which are called relative belong all which stand in need of some explanation, as that which is greater than something or quicker than something, or more beautiful and the like. For the greater implies a less, and the quicker is quicker than something. Thus existing things are either absolute or relative. And in this way, according to Aristotle, Plato used to divide the primary conceptions also.

There was also another man named Plato, a philosopher of Rhodes, a pupil of Panaetius, as is stated by Seleucus the grammarian in his first book On Philosophy; another a Peripatetic and pupil of Aristotle; and another who was a pupil of Praxiphanes; and lastly, there was Plato, the poet of the Old Comedy.
