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.

V1_349

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.[*](Plato probably refers to Carthage when he mentions purchasable kingship, ὠνηταὶ βασιλεῖαι, amongst barbarians, Rep. 544 d. Aristotle repeats the epithet in his description of the Carthaginian constitution, Pol. ii. 11, 1273 a 36. Polybius says that at Carthage magistrates attain office, δῶρα φανερῶς διδόντες, vi. 56. 4. This phrase is some help towards an explanation, but whether it means open bribery —possibly of the people, more probably of the Council— or whether it refers to very large fees payable upon taking office, it is not easy to determine. In either case wealth would preponderate over merit.)

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

V1_351
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

V1_353
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

V1_355
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

V1_357
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

V1_359
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

V1_361
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

V1_363
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.

V1_365

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.
