The Lives and Opinions of Eminent Philosophers

L. Of medical science there are five species: one, pharmaceutical; a second, manual; a third, conversant about the regulation of the manner of life, and the diet; a fourth, the business of which is to detect diseases; and the fifth is remedial. The pharmaceutical relieves infirmities by means of medicines; the manual heals men by cutting and cauterizing; the one which attends to the diet, gets rid of diseases by altering and regulating the diet; the fourth produces its effects by a thorough comprehension of the nature of the disease; and the last relieves men from suffering by bringing prompt assistance at the moment. Medical science, then, is divided into the pharmaceutical, the manual, the dietetic, the diagnostic, and the remedial.

LI. Of law there are two divisions. For there is a written and an unwritten law. The one by which we regulate our constitutions in our cities, is the written law; that which arises from custom, is the unwritten law. As, for instance, for a man to come naked into the market place, or to wear woman’s clothes, are actions which are not prohibited by any law, and yet we never do them because they are forbidden by the unwritten law. Law, therefore, is divided into the written and the unwritten law.

LII. Discourse is divided into five heads; one of which heads is that which statesmen employ when they speak in the public assemblies; and this is called political. Another division is that which orators use in their written harangues, and bring forward for the sake of display in panegyrics or reproaches, or impeachments. And such a description of discourse as this is the rhetorical. A third class is that which private individuals use when conversing with one another. This is called private discourse. Another kind is that which is employed when men converse by means of putting short questions and giving brief answers to those who question them. This is called the dialectic kind of discourse. The fifth division is that which artists adopt when conversing on their own particular art, and this is called professional discourse. Thus discourse, then, is divided into political, rhetorical, private, dialectic, and professional.

LIII. Music again is divided into three species. For there is the music of the mouth alone, such as song; secondly, there is the music which is performed by the hands and mouth together, such as singing to the harp; thirdly, there is that which is executed by the hands alone, such as harp playing. Music, therefore, is divided into music of the mouth, music of the mouth and hands, and music of the hands.

LIV. Nobleness of birth is divided into four species; the first is when one’s ancestors are noble, and valiant, and just; in which case they say that their posterity are nobly born. The second kind is when one’s ancestors have been princes and rulers of nations, and their posterity also we call noble. Another kind is when one’s ancestors have been distinguished for personal renown, such, for instance, as is gained by generalship or by victory at the games. For their offspring also we address as nobly born. And the last kind is when a man is himself noble in his spirit, and magnanimous. For that man also we call noble, and this is the last kind of nobility. There is, therefore, nobility arising from virtuous ancestors, from royal ancestors, from illustrious ancestors, and from one’s own excellent qualities.

LV. Beauty also is divided into three kinds. For there is one kind which is praiseworthy, as that of a beautiful face. Another which is useful, as an instrument or a house, and things of that kind which are beautiful, with reference to our use of them. There is also a beauty with reference to laws, and habits, and things of that kind, which is likewise beautiful, because of its utility. So that beauty again is looked at in three ways, with reference to its praise, its utility, and to our use of it.

LVI. The soul is divided into three parts; for one part of it is capable of reason, another is influenced by appetite, the third part is liable to passion. Of these the reasoning part is the cause of deliberating, and reasoning, and understanding, and everything of that kind. The appetite part is that portion of the soul which is the cause of desiring to eat, and to embrace and things of that kind. The passionate part is the cause of men feeling confidence and delight, and grief and anger. The soul therefore is divided into the reasoning part, the appetitive part, and the passionate part.

LVII. Of perfect virtue there are four species. One is prudence, one is justice, the third is manly gallantry, and the fourth is temperance. Of these, prudence is the cause of a man acting rightly in affairs; justice is the cause of his acting justly in partnerships and bargains; manly gallantry is the cause of a man’s not being alarmed amid dangers and formidable circumstances, but standing firm; and temperance is the cause of his subduing his appetites, and being enslaved by no pleasure, but living decorously. So that virtue is divided into prudence, justice, manly gallantry, and temperance.

LVIII. Rule is divided into five parts. One is rule according to law; another is rule according to nature; a third kind is rule according to custom; a fourth division is rule with reference to family; the fifth is rule by force. Now when the rulers in cities are elected by the citizens, then they rule according to law; those who rule according to nature are the males, not only among men, but also among all other animals; for everywhere we shall find it as a general rule that the male rules the female; the rule of him who rules according to custom is such as this, when schoolmasters rule their pupils, and teachers their disciples. Rule according to family is that which prevails in places like Lacedæmon, where hereditary sovereigns reign. For the kingdom there belongs to a certain family; and in Macedonia they rule on the same principle. For there, too, the kingdom depends on family. But those who rule by force, only cajoling the citizens, rule in spite of them; and such a sway is called rule by force. So that there is rule by law, and by nature, and by custom, and by family, and by force.

LIX. Of rhetoric he speaks of six species. For when orators exhort the people to make war upon or to form alliances against any one, this species of oratory is called exhortation. When they persuade the people not to make war, or to form alliances, but to keep quiet, this kind of rhetoric is called dissuasion. The third species of rhetoric, is when any one says that he has been injured by some one else, and impeaches that person as guilty of many crimes; for this species is called accusation. The fourth kind of rhetoric is called defence, when a man shows that he has done no wrong, and that he is not guilty of anything out of the way. Such a kind of speech they call a defence. The fifth species of rhetoric, is when any one speaks well of another, and shows him to be virtuous and honourable; and this kind is called encomium. The sixth species, is when any one shows that another person is worthless; and this kind is called blame. So that rhetoric is divided into encomium and blame, exhortation and dissuasion, accusation and defence.

Speaking correctly is divided under four heads. One, the saying what is right; one, the saying as much as is right; thirdly, the saying it to the proper people; and fourthly, the saying it at the proper time. Now as to the saying what is right, that is the saying what will be advantageous both to the speaker and to the hearer. The saying as much as is right, is saying neither more nor less than what is sufficient. The saying it to the proper people, is supposing one is speaking to one’s elders who are mistaken in any point, the using expressions proper to be addressed to those older than one’s self; or, on the other hand, if one is addressing those younger, then the using language such as is suitable to young people. The saying it at the proper time, is speaking neither too soon nor too late; for if one does, one will err and speak improperly.

LX. Beneficence is divided under four heads. For it may be exerted either in money, or by personal exertion, or by knowledge, or by words. In money when any one assists those who are in want, so as to put them at ease with respect to money. And men benefit one another by personal exertion when they come upon those who are being beaten and assist them. Again, those who instruct, or heal, or who teach any good thing, benefit others by their knowledge; and when one person comes down to the court of justice as an advocate for another, and delivers some speech full of sense and good feeling in his behalf, that man assists his friend by words. So that there is one beneficence which is displayed in money, another in personal exertion, a third by means of knowledge, and the fourth kind by words.

LXI. Again, Plato divides the end of all affairs into four species. An affair has one end in accordance with law, when a decree is passed, and when the law establishes it; it has an end in accordance with nature, when it is such a thing as a day, or a year, or the seasons. It has an end according to art, when it is architecture for instance, for a man builds a house; or when it is ship-building, for it makes a ship. And affairs also come to an end by chance, when they turn out differently from what any one expected. So that an end of an affair is regulated either by law, or by nature, or by art, or by chance.

LXII. Power again is divided into four species. There is one power which we possess by our ability to reason and form conceptions by means of our intellect. There is another power which we owe to the body, such as the power of walking, or giving, or taking, and such like. There is a third which we possess through the multitude of soldiers or riches, on which account a king is said to have great power. And the fourth division of power consists in the being well or ill treated, and treating others well or ill; as, for instance, we may be sick, or we may be taught, or we may be in vigorous health, and many more cases of that sort. So that one kind of power dwells in the intellect, another in the body, another in an army and riches, and another in our capacity as agents or patients.

LXIII. Of philanthropy there are three sorts. One which is displayed in addressing people, when some persons address every one whom they meet, and give them their right hand, and greet them heartily; another species is when one is disposed to assist every one who is unfortunate. The last kind is that sort of philanthropy which makes men pleasant boon companions. So that there is one kind of philanthropy displayed in addressing people, another in benefiting them, and a third in feasting and making merry with them.

LXIV. Happiness is divided into five parts. For one part of it is wisdom in counsel; another is a healthy condition of the sensations and general health of body; a third is good fortune in one’s affairs; a fourth kind is good reputation among men; a fifth is abundance of riches and of all those things which are useful in life. Now wisdom in counsel arises from good instruction, and from a person’s having experience of many things. A healthy condition of the sensations depends on the limbs of the body; as, for instance, when one sees with one’s eyes, and hears with one’s ears, and smells with one’s nose, and feels with one’s body, just what one ought to see, and hear, and smell, and feel. Such a condition as this is a healthy condition. And good fortune is when a man does rightly and successfully what a good and energetic man ought to do. And good reputation is when a man is well spoken of. And abundance of riches is when a man has such a sufficiency of everything which relates to the uses of life, that he is able to benefit his friends, and to discharge all public obligations in a splendid and liberal manner. And the man who has all these different parts of happiness, is a perfectly happy man. So that happiness is made up of wisdom in counsel, a good condition of the sensations and health of body, good fortune, good reputation, and riches.

LXV. The arts are divided into three kinds. The first, the second, and the third. The first are those of working mines and cutting wood, for these are preparatory arts. The second are such as working metals and carpentry, for they are alterative arts. For working in metals makes arms out of iron; and carpentry makes flutes and lyres out of wood. The third is the art which makes use of instruments; such as horsemanship, which uses bridles; the military art, which uses arms; music, which uses flutes and lyres. So that there are three species of art; one of which is the first, another the second, and another the third.

LXVI. Good is divided into four kinds. One of which we mean when we speak of a man endowed with private virtue, as good; another kind is that which we indicate, when we call virtue and justice, good. A third kind is that which we attribute to suitable food, and exercise, and medicine. The fourth good, is that which we mean, when we speak of good flute playing, good acting, and things of that sort. There are therefore four kinds of good. One the having virtue; another, virtue itself; a third, useful food and exercise; and fourthly, we call skill in flute playing and acting, good.

LXVII. Of things existing, some are bad, some good, and some neither one thing nor the other. Of these, we call those things bad, which are invariably capable of doing injury, such as intemperance, folly, injustice, and things of that sort. And the opposites to these qualities are good. But those things, which may at times be beneficial, and at times injurious, such as walking, sitting down, and eating; or which have absolutely no power in any case to benefit or injure any one; these are neither bad nor good. Of things existing then, there are some bad, and some good, and some of a neutral character, neither bad nor good.

LXVIII. A good state of affairs with reference to the laws, is divided under three heads. One when the laws are good, for that is a good state of affairs; so too is it, when the citizens abide by the existing laws; and the third case is, when although there are no positive laws, still men are good citizens in deference to custom and to established institutions; and this is also called a good state of affairs. So that of these three heads, one depends on the laws being good, another on obedience to existing laws, and the third on men yielding to good customs and institutions.

So again, lawlessness is divided into three heads. One of which is, when the laws are bad, both as concerns strangers, and the citizens; another, when the citizens do not obey the laws that are established; and the third is when there is actually no law at all. So that one kind of lawlessness arises from bad laws, another from disobedience to existing laws, and the third from the absence of laws.

LXIX. Contraries are of three sorts; for instance, we say that good is contrary to evil, as justice to injustice, wisdom to folly, and so on. Again, some evils are contrary to others, as extravagance is to stinginess, and the being tortured with justice to the being tortured with injustice. And such evils as these are the contraries of other evils. Again, the heavy is contrary to the light, the swift to the slow, the black to the white; so that some things which are of a neutral character, neither good nor evil, are contrary to other things of a neutral character. Of contraries then, there are some which are so, as what is good is contrary to what is evil; others, as one evil is contrary to another; and others again, as neutral things are contrary to other things of a neutral character.

LXX. Of good things there are three kinds; for there are some which can be possessed; others, which can be shared; others, which one realizes in one’s self. Those which can be possessed, are those which it is possible for a person to have, such as justice, or good health; those can be shared, which it is not possible for a person to have entirely to himself, but which he may participate in; as for instance, a person cannot be the sole possessor of abstract good, but he may participate in it. Those again a person realizes in himself, when they are such, that he cannot possess them himself, or share them with others, and yet they ought to exist; as for instance, it is good to be virtuous and just, but yet a man does not possess the being virtuous, or participate in it; but the being virtuous and just ought to exist in him. Of good things, therefore, there are those which are possessed, those which are shared, and those which ought to exist in a man.

LXXI. In the same manner, good counsel is divisible into three kinds. For there is one kind which is derived from past time, another from the future, another from the present. That which is derived from past time is made up of instances, as for instance what the Lacedæmonians suffered by trusting to such and such people. That which relates to the present, is when what is wanted, is to show that the fortifications are weak, the men cowardly, or the provisions scanty. That which concerns the future, is when the speaker urges that no injury ought to be offered to ambassadors, in order that Greece may not get an evil reputation; and supports his argument by instances. So that good counsel has reference, firstly to what is past, secondly to what is present, and thirdly to the future.

LXXII. Voice is divided into two parts, one of which is animated, and the other inanimate. That is animated, which proceeds from living animals, while sounds and echoes are inanimate. Again, animated voice may be divided into that which can be indicated by letters, and that which cannot; that which can be so indicated being the voice of men, and that which cannot being the voice of animals; so that one kind of voice is animated, the other inanimate.

LXXIII. Of existing things, some are divisible and some indivisible. Again, those which are divisible, consist either of similar or of dissimilar parts. Those which are indivisible are such as have no separate parts, and are not formed by any combination, such as unity, a point, or a sound. But those are divisible which are formed by some combination; as, for instance, syllables, and symphonies, and animals, and water, and gold. These too consist of similar parts, which are made up of particles resembling one another, and of which the whole does not differ from any part, except in number. As for instance, water and gold, and everything which is fusible, and so on. And these consist of dissimilar parts, which are made up of various things not resembling one another; as for instance, a house, and things of that sort; so that of existing things, some are divisible and others indivisible. And of those which are divisible, some consist of similar and others of dissimilar parts.

LXXIV. Again, of existing things, some are spoken of as having an independent, and some only a relative existence. Those which are spoken of as having an independent existence, are those which require nothing else to be added to them, when we are explaining their nature; as man, a horse, and the other animals; for these have no need of any additional explanation. But those things are said to have a relative existence which do require some additional explanation. As for instance, that which is greater than something else, or less, or swifter, or more beautiful, and so on. For that which is greater, is greater than something which is less; and that which is swifter, is swifter than something else. So that, of existing things, some are spoken of as independently, and other relatively. And thus he divided them at first, according to Aristotle.

LXXV. There was also another man of the name of Plato, a philosopher of Rhodes, a disciple of Panætius, as Seleucus, the grammarian says in the first book of his treatise on Philosophy; and another was a Peripatetic, a pupil of Aristotle; and there was a third, a pupil of Praxiphanes; and there was besides all these, the poet of the Old Comedy.
