(24) It is asserted that on this ground the Pythagoreans exercised abstinence. But to me, on the contrary, it seems that they marry for the sake of procreating children, but after they have begotten children they desire to control sexual indulgence. That is why they give the mysterious command to abstain from beans, not because pulse leads to flatulence and is indigestible and causes troubled dreams, nor because the bean is shaped like a man's head; as the verse has it, "It is alike to eat beans and the head of one's parents." The real reason is that if beans are eaten they make women barren. At any rate Theophrastus in the fifth book of his Causes of Plants relates that if the pods of beans are put round the roots of newly planted trees the shoots dry up and that if birds that live round houses are continuously fed on beans they become unable to lay eggs.

(461) Certainly, he said, both in men and women those years are the prime of physical as well as of intellectual vigour. Any one above or below the prescribed ages who takes part in the public hymeneals shall be said to have done an unholy and unrighteous thing; the child of which he is the father, if it steals into life, will have been conceived under auspices very unlike the sacrifices and prayers, which at each hymeneal priestesses and priest and the whole city will offer, that the new generation may be better and more useful than their good and useful parents, whereas his child will be the offspring of darkness and strange lust. Very true, he replied. And the same law will apply to any one of those within the prescribed age who forms a connection with any woman in the prime of life without the sanction of the rulers; for we shall say that he is raising up a bastard to the State, uncertified and unconsecrated. Very true, he replied. This applies, however, only to those who are within the specified age: after that we allow them to range at will, except that a man may not marry his daughter or his daughter’s daughter, or his mother or his mother’s mother; and women, on the other hand, are prohibited from marrying their sons or fathers, or son’s son or father’s father, and so on in either direction. And we grant all this, accompanying the permission with strict orders to prevent any embryo which may come into being from seeing the light; and if any force a way to the birth, the parents must understand that the offspring of such an union cannot be maintained, and arrange accordingly. That also, he said, is a reasonable proposition. But how

(546) 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, 1 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. 2 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 a hundred times as great (400 = 4 × 100), 3 and the other a figure having one side equal to the former, but oblong, 4 consisting of a hundred numbers squared upon rational diameters of a square (i.e. omitting fractions), the side of which is five (7 × 7 = 49 × 100 = 4900), each of them being less by one (than the perfect square which includes the fractions, sc. 50) or less by 5 two perfect squares of irrational diameters (of a square the side of which is five = 50 + 50 = 100); and a hundred cubes of three (27 × 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 predecessors, still they will be unworthy to hold their fathers’ 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 under-valuing music; which neglect will soon extend to gymnastic; 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

(18) And in another place: " Accordingly here the soul of the philosopher mostly disregards his body and flees from it, and seeks to be existent by itself." Does he not agree to some ex- tent with the divine apostle when he says, "0 wretched man that I am, who shall deliver me from this body of death?" unless he speaks of "body of death" in a figurative sense to refer to the agreement of those who have been enticed into evil. And that sexual intercourse, as the cause of birth, was rejected long before Marcion by Plato is clear from the first book of the Republic. For after praising old age he continues: "Mark it well, for me the more the other pleasures of the body fade away, the 49 more grow the desires and pleasures of rational enquiry." And with reference to sex relations: "Be silent, O man, it is with the greatest joy that I escaped from it-as if I had escaped from a wild and raging tyrant."

(12) Far more excellent, in my opinion, than the seeds of wheat and barley that are sown at appropriate seasons, is man that is sown, for whom all things grow; and those seeds temperate husbandmen ever sow. Every foul and polluting practice must therefore be purged away from marriage; that the intercourse of the irrational animals may not be cast in our teeth, as more accordant with nature than human conjunction in procreation. Some of these, it must be granted, desist at the time in which they are directed, leaving creation to the working of Providence.

(403) None whatever. Any affinity to wantonness and intemperance? Yes, the greatest. And is there any greater or keener pleasure than that of sensual love? No, nor a madder. Whereas true love is a love of beauty and order—temperate and harmonious? Quite true, he said. Then no intemperance or madness should be allowed to approach true love? Certainly not. Then mad or intemperate pleasure must never be allowed to come near the lover and his beloved; neither of them can have any part in it if their love is of the right sort? No, indeed, Socrates, it must never come near them. Then I suppose that in the city which we are founding you would make a law to the effect that a friend should use no other familiarity to his love than a father would use to his son, and then only for a noble purpose, and he must first have the other’s consent; and this rule is to limit him in all his intercourse, and he is never to be seen going further, or, if he exceeds, he is to be deemed guilty of coarseness and bad taste. I quite agree, he said. Thus much of music, which makes a fair ending; for what should be the end of music if not the love of beauty? I agree, he said. After music comes gymnastic, in which our youth are next to be trained. Certainly. Gymnastic as well as music should begin in early years; the training in it should be careful and should continue through life.

(458) they will be together, and will be brought up together, and will associate at gymnastic exercises. And so they will be drawn by a necessity of their natures to have intercourse with each other—necessity is not too strong a word, I think? Yes, he said;—necessity, not geometrical, but another sort of necessity which lovers know, and which is far more convincing and constraining to the mass of mankind. True, I said; and this, Glaucon, like all the rest, must proceed after an orderly fashion; in a city of the blessed, licentiousness is an unholy thing which the rulers will forbid. Yes, he said, and it ought not to be permitted. Then clearly the next thing will be to make matrimony sacred in the highest degree, and what is most beneficial will be deemed sacred? Exactly. And how can marriages be made most beneficial?—that is a question which I put to you, because I see in your house dogs for hunting, and of the nobler sort of birds not a few. Now, I beseech you, do tell me, have you ever attended to their pairing and breeding? In what particulars? Why, in the first place, although they are all of a good sort, are not some better than others? True. And do you breed from them all indifferently, or do you take care to breed from the best only? From the best.

(60) Bonellus* saith: Know, all ye disciples, that out of the elect things nothing becomes useful without conjunction and regimen,* because sperma is generated out of blood and desire. For the man mingling with the woman, the sperm is nourished by the humour of the womb, and by the moistening blood, and by heat, and when forty nights have elapsed the sperm is formed. But if the humidity of the blood and of the womb were not heat, the sperm would not be dissolved, nor the foetus be procreated. But God has constituted that heat and blood for the nourishment of the sperm until the foetus is brought forth, after which it is not nourished, save by milk and fire, sparingly and gradually, while it is dust, and the more it burns the more, the bones being strengthened, it is led towards youth, arriving at which it is independent.t Thus it behoves you also to act in this Art. Know ye that without heat nothing is ever generated, and that the bath causes the matter to perish by means of intense heat. If, indeed, it be frigid, it puts to flight and disperses, but if it have been tempered, it is convenient and sweet to the body, wherefore the veins become smooth and the flesh is augmented. Behold it has been demonstrated to you, all ye disciples! Understand, therefore, and in all things which ye attempt to rule, fear God.
