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.
