The Republic — Plato

Then if the constitutions of States are five, the dispositions of individual minds will also be five? Certainly. Him who answers to aristocracy, and whom we rightly call just and good, we have already described. We have. Then let us now proceed to describe the inferior sort of natures, being the contentious and ambitious, who answer to the Spartan polity ; also the oligarchical, democratical, and tyrannical.

Let us place the most just by the side of the most unjust, and when we see them we shall be able to compare the relative happiness or unhappiness of him who leads a life of pure justice or pure injustice. The inquiry will then be completed. And we shall know whether we ought to pursue injustice, as Thrasymachus advises, or in accordance with the conclusions of the argument to prefer justice. Certainly, he replied, we must do as you say.

Shall we follow our old plan, which we adopted with a view to clearness, of taking the State first and then proceeding to the individual, and begin with the government of honor? — I know of no name for such a government other than timocracy or perhaps timarchy.

We will compare with this the like character in the individual ; and, after that, consider oligarchy and the oligarchical man ; and then again we will turn our attention to democracy and the democratical man; and lastly, we will go and view the city of tyranny, and once more take a look into the tyrant's soul, and try to arrive at a satisfactory decision. That way of viewing and judging of the matter will be very suitable.

First, then, I said, let us inquire how timocracy (the government of honor) arises out of aristocracy (the government of the best). Clearly, all political changes originate in divisions of the actual governing power ; a government which is united, however small, cannot be moved. Very true, he said.

In what way, then, will our city be moved, and in what manner will the two classes of auxiliaries and rulers disagree among themselves or with one another? Shall we, after the manner of Homer, pray the muses to tell us " how discord first arose " ?

Shall we imagine them in solemn mockery, to play and jest with us as if we were children, and to address us in a lofty tragic vein, making believe to be in earnest? How would they address us? After this manner: A city which is thus constituted can hardly be shaken ; but, seeing that everything which has a beginning has also an end, even a constitution such as yours will not last forever, but will in time be dissolved.

And this is the dissolution : In plants that grow in the earth, as well as in animals that move on the earth's surface, fertility and sterility of soul and body occur when the circumferences of the circles of each are completed, which in short-lived existences pass over a short space, and in long-lived ones over a long space.

But to the knowledge of human fecundity and sterility all the wisdom and education of your rulers will not attain; the laws which regulate them will not be discovered by an intelligence which is alloyed with sense, but will escape them, and they will bring children into the world when they ought not.

Now that which is of divine birth has a period which is contained in a perfect number,^ but the period of human birth is comprehended in a number in which first increments by involution and evolution (or squared and cubed) obtaining three intervals and four terms of like and unlike, waxing and waning numbers, make all the terms commensurable and agreeable to one another.^ The base of these (3) with a third added (4), when combined with five (20) and raised to the third power, furnishes two harmonies; the first a square which is 100 times as great (400 = 4 X 100),* and the other a figure having one side equal to the former, but oblong,* consisting of 100 numbers squared upon rational diameters of a square (i.e., omitting fractions), the side of which is five (7 X 7 = 49 X 100 = 4900) , each of them being less by one (than the perfect square which includes the fractions, sc.

50) or less by ^ two perfect squares of irrational diameters (of a square the side of which is five = 50 + 50 = ' I.e., a cyclical number, such as 6, which is equal to the sum of its divisors, i, 2, 3, so that when the circle or time represented by 6 is completed, the lesser times or rotations represented by i, 2, 3 are also completed. ^ Probably the numbers 3, 4, 5. 6, of which the three first = the sides of the Pythagorean trinngle.

The terms will tlien be 3^, 4', 5', which together = 6' = 216. ^ Or the first a square, which is 100 x 100 = 10000. The whole number will then be 17, 500 = a square of 100 and an oblong of 100 by 75. * Reading 1^po^L■l^K^} fie. ' Or, "consisting of two numbers squared upon irrational diameters," etc. = 100. For other explanations of the passage see Introduction.

lOo) ; and lOO cubes of three (27 X 100 = 2700 + 4900 + 400 = 8000). Now this number represents a geometrical figure which has control over the good and evil of births. For when your guardians are ignorant of the law of births, and unite bride and bridegroom out of season, the children will not be goodly or fortunate.

And though only the best of them will be appointed by their predecessor, still they will be unworthy to hold their father's places, and when they come into power as guardians they will soon be found to fail in taking care of us, the muses, first by undervaluing music; which neglect will soon extend to gymnastics ; and hence the young men of your State will be less cultivated.

In the succeeding generation rulers will be appointed who have lost the guardian power of testing the metal of your different races, which, like Hesiod's, are of gold and silver and brass and iron. And so iron will be mingled with silver, and brass with gold, and hence there will arise dissimilarity and inequality and irregularity, which always and in all places are causes of hatred and war.

This the muses affirm to be the stock from which discord has sprung, wherever arising ; and this is their answer to us. Yes, and we may assume that they answer truly. Why, yes, I said, of course they answer truly ; how can the muses speak falsely? And what do the muses say next ?

When discord arose, then the two races were drawn different ways : the iron and brass fell to acquiring money, and land, and houses, and gold, and silver ; but the gold and silver races, not wanting money, but having the true riches in their own nature, inclined toward virtue and the ancient order of things.

There was a battle between them, and at last they agreed to distribute their land and houses among individual owners; and they enslaved their friends and maintainers, whom they had formerly protected in the condition of freemen, and made of them subjects and servants ; and they themselves were engaged in war and in keeping a watch against them. I believe that you have rightly conceived the origin of the change. And the new government which thus arises will be of a form intermediate between oligarchy and aristocracy? Very true.
