“How?”
“As follows. Although it is difficult to disturb a city that has been constituted in this way, never-
theless, since destruction is the lot of anything that has come into being, even something constituted
like this will not endure for all time. It too will be dissolved, and its dissolution will be as follows.
Not alone for the plants in the earth, but also among the animals on the earth there is productiveness
and sterility of their souls and bodies as they run their circular course and complete their cycles,
which are short for those who are short-lived, and longer for the long-lived. But for your race,
although the people whom you educated as leaders of the city are wise, they will be unable by cal-
culation combined with sense experience, to hit upon the best time for bringing children to birth
and for not bearing children. This will evade them, and they will, on occasion, bring forth children
when they should not.
“Now, divine birth has a cycle that the perfect number encompasses. But for a human
being the number is the first in which root and square increases, having comprehended three
distances and four limits of whatever brings about likenesses and unlikenesses, waxings and
wanings, renders all things mutually agreeable and expressible towards one another. Of these
four, three yoked together with five yields two harmonies when increased threefold. The first is
equal, an equal number of times, one hundred times this amount. The other is equal in length on
one side, but it is oblong on the other side of one hundred squares of rational diameters of five
diminished by one each, or, if of irrational diameters, by two, on the other side of one hundred
cubes of three.
“This entire geometrical number is lord of anything like this,
3
of better and worse births.
And whenever our guardians, in ignorance of this, make brides cohabit with bridegrooms inap-
propriately, their children will be neither well developed nor fortunate. And although their prede-
cessors will install the best of them in power, nevertheless, being unworthy, when their turn comes
to rule and exercise the powers of their fathers, they will begin, as guardians, firstly to pay little
heed to us Muses by regarding our realm of music as less important, and secondly they will neglect
the realm of gymnastics too, and so your own young people will become less musical. From these,
rulers will be installed who cannot exercise much guardianship when it comes to testing for the
races of Hesiod,

and of your people too, the gold, silver, bronze and iron. The indiscriminate mix-
ing of iron with silver and of bronze with gold will produce dissimilarity and an inappropriate
inconsistency, which always beget war and enmity wherever they arise. So, we should declare that
‘such is the lineage’ of faction,
5
whenever and wherever it occurs.”
“And we shall declare,” said he, “that they have answered correctly.”
“As they must,” said I, “since they are Muses.”
“Well, then,” said he, “what shall the Muses say next?”
“Once faction had arisen,” said I, “both races began to exert their influence, the iron and brass
kinds drawing the city towards the acquisition of money, land and property, gold and silver, while
the gold and silver kinds, for their part – since these are not in poverty but are naturally wealthy
of soul – led in the direction of excellence and the ancient order. As they struggled violently in
opposite directions, they eventually agreed to compromise, distribute land and property for them-
selves, and make these private. With this, they enslaved those they had previously guarded as free
men, friends and supporters by treating them as serfs and underlings, while they themselves
attended to warfare and guarding themselves against their former friends.”
“I think,” said he, “that this is how the change comes about.”
“Would not this form of government,” said I, “be something in between aristocracy and oligarchy?”
“Very much so.”
“Well, that is how it will change, but once it has changed, how will it be administered? Or is it
obvious that in some respects it will imitate the previous form of government, and in other respects
