But that there are many different states, and from what causes they arise, has been already mentioned: and that there are also different species both of democracies and oligarchies we will now show. Though this indeed is evident from what we have already said: there are also many different sorts of common people, and also of those who are called gentlemen. Of the different sorts of the first are husbandmen, artificers, exchange-men, who are employed in buying and selling, seamen, of which some are engaged in war, some in traffic, some in carrying goods and passengers from place to place, others in fishing, and of each of these there are often many, as fishermen at Tarentum and Byzantium, masters of galleys at Athens, merchants at AEgina and Chios, those who let ships on freight at Tenedos; we may add to these those who live by their manual labour and have but little property; so that they cannot live without some employ: and also those who are not free-born on both sides, and whatever other sort of common people there may be. As for gentlemen, they are such as are distinguished either by their fortune, their birth, their abilities, or their education, or any such-like excellence which is attributed to them. The most pure democracy is that which is so called principally from that equality which prevails in it: for this is what the law in that state directs; that the poor shall be in no greater subjection than the rich; nor that the supreme power shall be lodged with either of these, but that both shall share it. For if liberty and equality, as some persons suppose, are chiefly to be found in a democracy, it must be most so by every department of government being alike open to all; but as the people are the majority, and what they vote is law, it follows that such a state must be a democracy. This, then, is one species thereof. Another is, when the magistrates are elected by a certain census; but this should be but small, and every one who was included in it should be eligible, but as soon as he was below it should lose that right. [1292a] Another sort is, in which every citizen who is not infamous has a share in the government, but where the government is in the laws. Another, where every citizen without exception has this right. Another is like these in other particulars, but there the people govern, and not the law: and this takes place when everything is determined by a majority of votes, and not by a law; which happens when the people are influenced by the demagogues: for where a democracy is governed by stated laws there is no room for them, but men of worth fill the first offices in the state: but where the power is not vested in the laws, there demagogues abound: for there the people rule with kingly power: the whole composing one body; for they are supreme, not as individuals but in their collective capacity.
