we have determined to be the more pleasant life.  And we should say that the temperate life has the elements both of pleasure and pain fewer and smaller and less frequent than the intemperate, and the wise life than the foolish life, and the life of courage than the life of cowardice; one of each pair exceeding in pleasure and the other in pain, the courageous surpassing the cowardly, and the wise exceeding the foolish.  And so the one class of lives exceeds the other class in pleasure; the temperate and courageous and wise and healthy exceed the cowardly and foolish and intemperate and diseased lives; and generally speaking, that which has any virtue, whether of body or soul, is pleasanter than the vicious life, and far superior in beauty and rectitude and excellence and reputation, and causes him who lives accordingly to be infinitely happier than the opposite.

Enough of the preamble; and now the laws should follow; or, to speak more correctly, an outline of them.  As, then, in the case of a web or any other tissue, the warp and the woof cannot be made of the same materials (compare Statesman), but the warp is necessarily superior as being stronger, and having a certain character of firmness, whereas the woof is softer and has a proper degree of elasticity;—­in a similar manner those who are to hold great offices in states, should be distinguished truly in each case from those who have been but slenderly proven by education.  Let us suppose that there are two parts in the constitution of a state—­one the creation of offices, the other the laws which are assigned to them to administer.

But, before all this, comes the following consideration:—­The shepherd or herdsman, or breeder of horses or the like, when he has received his animals will not begin to train them until he has first purified them in a manner which befits a community of animals; he will divide the healthy and unhealthy, and the good breed and the bad breed, and will send away the unhealthy and badly bred to other herds, and tend the rest, reflecting that his labours will be vain and have no effect, either on the souls or bodies of those whom nature and ill nurture have corrupted, and that they will involve in destruction the pure and healthy nature and being of every other animal, if he should neglect to purify them.  Now the case of other animals is not so important—­they are only worth introducing for the sake of illustration; but what relates to man is of the highest importance; and the legislator should make enquiries, and indicate what is proper for each one in the way of purification and of any other procedure.  Take, for example, the purification of a city—­there are many kinds of purification, some easier and others more difficult; and some of them, and the best and most difficult of them, the legislator, if he be also a despot, may be able to effect; but the legislator, who, not being a despot, sets up a new government and laws, even if he attempt the mildest of purgations, may think himself happy
