If then the legislator ought to take care that the bodies of the children are as perfect as possible, his first attention ought to be given to matrimony; at what time and in what situation it is proper that the citizens should engage in the nuptial contract. Now, with respect to this alliance, the legislator ought both to consider the parties and their time of life, that they may grow old at the same part of time, and that their bodily powers may not be different; that is to say, the man being able to have children, but the woman too old to bear them; or, on the contrary, the woman be young enough to produce children, but the man too old to be a father; for from such a situation discords and disputes continually arise. In the next place, with respect to the succession of children, there ought not to be too great an interval of time between them and their parents; for when there is, the parent can receive no benefit from his child's affection, or the child any advantage from his father's protection; [1335a] neither should the difference in years be too little, as great inconveniences may arise from it; as it prevents that proper reverence being shown to a father by a boy who considers him as nearly his equal in age, and also from the disputes it occasions in the economy of the family. But, to return from this digression, care ought to be taken that the bodies of the children may be such as will answer the expectations of the legislator; this also will be affected by the same means. Since season for the production of children is determined (not exactly, but to speak in general), namely, for the man till seventy years, and the woman till fifty, the entering into the marriage state, as far as time is concerned, should be regulated by these periods. It is extremely bad for the children when the father is too young; for in all animals whatsoever the parts of the young are imperfect, and are more likely to be productive of females than males, and diminutive also in size; the same thing of course necessarily holds true in men; as a proof of this you may see in those cities where the men and women usually marry very young, the people in general are very small and ill framed; in child-birth also the women suffer more, and many of them die. And thus some persons tell us the oracle of Traezenium should be explained, as if it referred to the many women who were destroyed by too early marriages, and not their gathering their fruits too soon. It is also conducive to temperance not to marry too soon; for women who do so are apt to be intemperate. It also prevents the bodies of men from acquiring their full size if they marry before their growth is completed; for this is the determinate period, which prevents any further increase; for which reason the proper time for a woman to marry is eighteen, for a man thirty-seven, a little more or less; for when they marry at that time their bodies are in perfection, and they will also cease to have children at a proper time; and moreover with respect to the succession of the children, if they have them at the time which may reasonably be expected, they will be just arriving into perfection when their parents are sinking down under the load of seventy years. And thus much for the time which is proper for marriage; but moreover a proper season of the year should be observed, as many persons do now, and appropriate the winter for this business. The married couple ought also to regard the precepts of physicians and naturalists, each of whom have treated on these [1335b] subjects. What is the fit disposition of the body will be better mentioned when we come to speak of the education of the child; we will just slightly mention a few particulars. Now, there is no occasion that any one should have the habit of body of a wrestler to be either a good citizen, or to enjoy a good constitution, or to be the father of healthy children; neither should he be infirm or too much dispirited by misfortunes, but between both these. He ought to have a habit of labour, but not of too violent labour; nor should that be confined to one object only, as the wrestler's is; but to such things as are proper for freemen. These things are equally necessary both for men and women. Women with child should also take care that their diet is not too sparing, and that they use sufficient exercise; which it will be easy for the legislator to effect if he commands them once every day to repair to the worship of the gods who are supposed to preside over matrimony. But, contrary to what is proper for the body, the mind ought to be kept as tranquil as possible; for as plants partake of the nature of the soil, so does the child receive much of the disposition of the mother. With respect to the exposing or bringing up of children, let it be a law, that nothing imperfect or maimed shall be brought up,.......... As the proper time has been pointed out for a man and a woman to enter into the marriage state, so also let us determine how long it is advantageous for the community that they should have children; for as the children of those who are too young are imperfect both in body and mind, so also those whose parents are too old are weak in both: while therefore the body continues in perfection, which (as some poets say, who reckon the different periods of life by sevens) is till fifty years, or four or five more, the children may be equally perfect; but when the parents are past that age it is better they should have no more. With respect to any connection between a man and a woman, or a woman and a man, when either of the parties are betrothed, let it be held in utter detestation [1336a] on any pretext whatsoever; but should any one be guilty of such a thing after the marriage is consummated, let his infamy be as great as his guilt deserves.
