St. Jerome, in bk. 1 of his Against Jovinianus §47, gives the only source for the philosopher Theophrastus's On Marriage, "worth its weight in gold," in which he answers the question
whether a wise man marries. And after laying down the conditions — that the wife must be fair, of good character, and honest parentage, the husband in good health and of ample means, and after saying that under these circumstances a wise man sometimes enters the state of matrimony, he immediately proceeds thusBut all these conditions are seldom satisfied in marriage. A wise man therefore must not take a wife. For in the first place his study of philosophy will be hindered, and it is impossible for anyone to attend to his books and his wife. Matrons want many things, costly dresses, gold, jewels, great outlay, maid-servants, all kinds of furniture, litters and gilded coaches. Then come curtain-lectures the livelong night: she complains that one lady goes out better dressed than she: that another is looked up to by all: 'I am a poor despised nobody at the ladies' assemblies.' 'Why did you ogle that creature next door?' 'Why were you talking to the maid?' 'What did you bring from the market?' 'I am not allowed to have a single friend, or companion.' She suspects that her husband's love goes the same way as her hate. There may be in some neighbouring city the wisest of teachers; but if we have a wife we can neither leave her behind, nor take the burden with us. To support a poor wife, is hard: to put up with a rich one, is torture. Notice, too, that in the case of a wife you cannot pick and choose: you must take her as you find her. If she has a bad temper, or is a fool, if she has a blemish, or is proud, or has bad breath, whatever her fault may be — all this we learn after marriage. Horses, asses, cattle, even slaves of the smallest worth, clothes, kettles, wooden seats, cups, and earthenware pitchers, are first tried and then bought: a wife is the only thing that is not shown before she is married, for fear she may not give satisfaction. Our gaze must always be directed to her face, and we must always praise her beauty: if you look at another woman, she thinks that she is out of favour. She must be called my lady, her birth-day must be kept, we must swear by her health and wish that she may survive us, respect must be paid to the nurse, to the nursemaid, to the father's slave, to the foster-child, to the handsome hanger-on, to the curled darling who manages her affairs, and to the eunuch who ministers to the safe indulgence of her lust: names which are only a cloak for adultery. Upon whomsoever she sets her heart, they must have her love though they want her not. If you give her the management of the whole house, you must yourself be her slave. If you reserve something for yourself, she will not think you are loyal to her; but she will turn to strife and hatred, and unless you quickly take care, she will have the poison ready. If you introduce old women, and soothsayers, and prophets, and vendors of jewels and silken clothing, you imperil her chastity; if you shut the door upon them, she is injured and fancies you suspect her. But what is the good of even a careful guardian, when an unchaste wife cannot be watched, and a chaste one ought not to be? For necessity is but a faithless keeper of chastity, and she alone really deserves to be called pure, who is free to sin if she chooses. If a woman be fair, she soon finds lovers; if she be ugly, it is easy to be wanton. It is difficult to guard what many long for. It is annoying to have what no one thinks worth possessing. But the misery of having an ugly wife is less than that of watching a comely one. Nothing is safe, for which a whole people sighs and longs. One man entices with his figure, another with his brains, another with his wit, another with his open hand. Somehow, or sometime, the fortress is captured which is attacked on all sides. Men marry, indeed, so as to get a manager for the house, to solace weariness, to banish solitude; but a faithful slave is a far better manager, more submissive to the master, more observant of his ways, than a wife who thinks she proves herself mistress if she acts in opposition to her husband, that is, if she does what pleases her, not what she is commanded. But friends, and servants who are under the obligation of benefits received, are better able to wait upon us in sickness than a wife who makes us responsible for her tears (she will sell you enough to make a deluge for the hope of a legacy), boasts of her anxiety, but drives her sick husband to the distraction of despair. But if she herself is poorly, we must fall sick with her and never leave her bedside. Or if she be a good and agreeable wife (how rare a bird she is!), we have to share her groans in childbirth, and suffer torture when she is in danger. A wise man can never be alone. He has with him the good men of all time, and turns his mind freely wherever he chooses. What is inaccessible to him in person he can embrace in thought. And, if men are scarce, he converses with God. He is never less alone than when alone. Then again, to marry for the sake of children, so that our name may not perish, or that we may have support in old age, and leave our property without dispute, is the height of stupidity. For what is it to us when we are leaving the world if another bears our name, when even a son does not all at once take his father's title, and there are countless others who are called by the same name. Or what support in old age is he whom you bring up, and who may die before you, or turn out a reprobate? Or at all events when he reaches mature age, you may seem to him long in dying. Friends and relatives whom you can judiciously love are better and safer heirs than those whom you must make your heirs whether you like it or not. Indeed, the surest way of having a good heir is to ruin your fortune in a good cause while you live, not to leave the fruit of your labour to be used you know not how.
