Aristotle, Politics, 1252a1-1253a40:

[1252a][1] Every state is as we see a sort of partnership, and every partnership is formed with a view to some good (since all the actions of all mankind are done with a view to what they think to be good). It is therefore evident that, while all partnerships aim at some good the partnership that is the most supreme of all and includes all the others does so most of all, and aims at the most supreme of all goods; and this is the partnership entitled the state, the political association. Those then who think that the natures of the statesman, the royal ruler, the head of an estate² and the master of a family are the same, are mistaken (they imagine that the difference between these various forms of authority is one of greater and smaller numbers, not a difference in the kind--that is, that the ruler over a few people is a master, over more the head of an estate, over more still a statesman or royal ruler, as if there were no difference between a large household and a small city; and also as to the statesman and the royal ruler, they think that one who governs as sole head is royal, and one who, while the government follows the principles of the science of royalty, takes turns to govern and be governed is a statesman; but these views are not true). And a proof that these people are mistaken will appear if we examine the question in accordance with our regular method of investigation. In every other matter it is necessary to analyze the composite whole down to its uncompounded elements (for these are the smallest [20] parts of the whole); so too with the state, by examining the elements of which it is composed we shall better discern in relation to these different kinds of rulers what is the difference between them, and whether it is possible to obtain any scientific precision in regard to the various statements made above.

In this subject as in others the best method of investigation is to study things in the process of development from the beginning. The first coupling together of persons then to which necessity gives rise is that between those who are unable to exist without one another: for instance the union of female and male for the continuance of the species (and this not of deliberate purpose, but with man as with the other animals and with plants there is a natural instinct to desire to leave behind one another being of the same sort as oneself); and the union of natural ruler and natural subject for the sake of security (for he that can foresee with his mind is naturally ruler and naturally master, and he that can do these things with his body is subject and naturally a slave; so that master and slave have the same interest).

[1252b][1] Thus the female and the slave are by nature distinct (for nature makes nothing as the cutlers make the Delphic knife,¹ in a niggardly way, but one thing for one purpose; for so each tool will be turned out in the finest perfection, if it serves not many uses but one). Yet among barbarians the female and the slave have the same rank; and the cause of this is that barbarians have no class of natural rulers, but with them the conjugal partnership is a partnership of female slave and male slave. Hence the saying of the poets --

'Tis meet that Greeks should rule barbarians,--

implying that barbarian and slave are the same in nature. From these two partnerships then is first composed the household, and Hesiod was right when he wrote

First and foremost a house and a wife and an ox for the ploughing—

for the ox serves instead of a servant for the poor. The partnership therefore that comes about in the course of nature for everyday purposes is the 'house,' the persons whom Charondas speaks of as 'meal-tub-fellows' and the Cretan Epimenides as 'manger-fellows.'

On the other hand the primary partnership made up of several households for the satisfaction of not mere daily needs is the village. The village according to the most natural account seems to be a colony from a household, formed of those whom some people speak of as 'fellow-sucklings,' sons and sons' sons. It is owing to this that our cities were at first under royal sway and that foreign races are so still, [20] because they were made up of parts that were under royal rule; for every household is under the royal rule of its eldest member, so that the colonies from the household were so too, because of the kinship of their members. And this is what Homer means:

And each one giveth law

To sons and eke to spouses--

for his Cyclopes live in scattered families; and that is the way in which people used to live in early times. Also this explains why all races speak of the gods as ruled by a king, because they themselves too are some of them actually now so ruled and in other cases used to be of old; and as men imagine the gods in human form, so also they suppose their manner of life to be like their own.

The partnership finally composed of several villages is the city-state; it has at last attained the limit of virtually complete self-sufficiency, and thus, while it comes into existence for the sake of life, it exists for the good life. Hence every city-state exists by nature, inasmuch as the first partnerships so exist; for the city-state is the end of the other partnerships, and nature is an end, since that which each thing is when its growth is completed we speak of as being the nature of each thing, for instance of a man, a horse, a household. Again, the object for which a thing exists, its end, is its chief good;

[1253a][1] and self-sufficiency is an end, and a chief good. From these things therefore it is clear that the city-state is a natural growth, and that man is by nature a political animal, and a man that is by nature and not merely by fortune citiless is either low in the scale of humanity or above it (like the

clanless, lawless, hearthless

man reviled by Homer, for one by nature unsocial is also 'a lover of war') inasmuch as he is solitary, like an isolated piece at draughts. And why man is a political animal in a greater measure than any bee or any gregarious animal is clear. For nature, as we declare, does nothing without purpose; and man alone of the animals possesses speech. The mere voice, it is true, can indicate pain and pleasure, and therefore is possessed by the other animals as well (for their nature has been developed so far as to have sensations of what is painful and pleasant and to indicate those sensations to one another), but speech is designed to indicate the advantageous and the harmful, and therefore also the right and the wrong; for it is the special property of man in distinction from the other animals that he alone has perception of good and bad and right and wrong and the other moral qualities, and it is partnership in these things that makes a household and a city-state.

Thus also the city-state is prior in nature to the household and to each of us individually. [20] For the whole must necessarily be prior to the part; since when the whole body is destroyed, foot or hand will not exist except in an equivocal sense, like the sense in which one speaks of a hand sculptured in stone as a hand; because a hand in those circumstances will be a hand spoiled, and all things are defined by their function and capacity, so that when they are no longer such as to perform their function they must not be said to be the same things, but to bear their names in an equivocal sense. It is clear therefore that the state is also prior by nature to the individual; for if each individual when separate is not self-sufficient, he must be related to the whole state as other parts are to their whole, while a man who is incapable of entering into partnership, or who is so self-sufficing that he has no need to do so, is no part of a state, so that he must be either a lower animal or a god.

Therefore the impulse to form a partnership of this kind is present in all men by nature; but the man who first united people in such a partnership was the greatest of benefactors. For as man is the best of the animals when perfected, so he is the worst of all when sundered from law and justice. For unrighteousness is most pernicious when possessed of weapons, and man is born possessing weapons for the use of wisdom and virtue, which it is possible to employ entirely for the opposite ends. Hence when devoid of virtue man is the most unholy and savage of animals, and the worst in regard to sexual indulgence and gluttony. Justice on the other hand is an element of the state; for judicial procedure, which means the decision of what is just, is the regulation of the political partnership.
