All the circumstances, accompaniments, and results of domestic jealousy in their completely typical form, are well illustrated by a very serious episode in the history of the Pepys household, and have been fully and faithfully set down by the great diarist. The offence—an embrace of his wife's lady-help, as she might now be termed—was a slight one, but, as Pepys himself admits, quite inexcusable. He is writing, being in his thirty-sixth year, on the 25th of Oct., 1668 (Lord's Day). "After supper, to have my hair combed by Deb, which occasioned the greatest sorrow to me that ever I knew in this world, for my wife, coming up suddenly, did find me embracing the girl.... I was at a wonderful loss upon it, and the girl also, and I endeavored to put it off, but my wife was struck mute and grew angry.... Heartily afflicted for this folly of mine.... So ends this month," he writes a few days later, "with some quiet to my mind, though not perfect, after the greatest falling out with my poor wife, and through my folly with the girl, that ever I had, and I have reason to be sorry and ashamed of it, and more to be troubled for the poor girl's sake. Sixth November. Up, and presently my wife up with me, which she professedly now do every day to dress me, that I may not see Willet [Deb], and do eye me, whether I cast my eye upon her, or no, and do keep me from going into the room where she is. Ninth November. Up, and I did, by a little note which I flung to Deb, advise her that I did continue to deny that ever I kissed her, and so she might govern herself. The truth is that I did adventure upon God's pardoning me this lie, knowing how heavy a thing it would be for me, to the ruin of the poor girl, and next knowing that if my wife should know all it would be impossible for her ever to be at peace with me again, and so our whole lives would be uncomfortable. The girl read, and as I bid her returned me the note, flinging it to me in passing by." Next day, however, he is "mightily troubled," for his wife has obtained a confession from the girl of the kissing. For some nights Mr. and Mrs. Pepys are both sleepless, with much weeping on either side. Deb gets another place, leaving on the 14th of November, and Pepys is never able to see her before she leaves the house, his wife keeping him always under her eye. It is evident that Pepys now feels strongly attracted to Deb, though there is no evidence of this before she became the subject of the quarrel. On the 13th of November, hearing she was to leave next day, he writes: "The truth is I have a good mind to have the maidenhead of this girl." He was, however, the "more troubled to see how my wife is by this means likely forever to have her hand over me, and that I shall forever be a slave to her—that is to say, only in matters of pleasure." At the same time his love for his wife was by no means diminished, nor hers for him. "I must here remark," he says, "that I have lain with my moher [i.e., muger, wife] as a husband more times since this falling out than in, I believe, twelve months before. And with more pleasure to her than in all the time of our marriage before." The next day was Sunday. On Monday Pepys at once begins to make inquiries which will put him on the track of Deb. On the 18th he finds her. She gets up into the coach with him, and he kisses her and takes liberties with her, at the same time advising her "to have a care of her honor and to fear God," allowing no one else to do what he has done; he also tells her how she can find him if she desires. Pepys now feels that everything is settled satisfactorily, and his heart is full of joy. But his joy is short-lived, for Mrs. Pepys discovers this interview with Deb on the following day. Pepys denies it at first, then confesses, and there is a more furious scene than ever. Pepys is now really alarmed, for his wife threatens to leave him; he definitely abandons Deb, and with prayers to God resolves never to do the like again. Mrs. Pepys is not satisfied, however, till she makes her husband write a letter to Deb, telling her that she is little better than a whore, and that he hates her, though Deb is spared this, not by any stratagem of Pepys, but by the considerateness of the friend to whom the letter was entrusted for delivery. Moreover, Mrs. Pepys arranges with her husband that, in future, whenever he goes abroad he shall be accompanied everywhere by his clerk. We see that Mrs. Pepys plays with what appears to be triumphant skill and success the part of the jealous and avenging wife, and digs her little French heels remorselessly into her prostrate husband and her rival. Unfortunately, we do not know what the final outcome was, for a little later, owing to trouble with his eyesight, Pepys was compelled to bring his Diary to an end. It is evident, however, when we survey the whole of this perhaps typical episode, that neither husband nor wife were in the slightest degree prepared for the commonplace position into which they were thrown; that each of them appears in a painful, undignified, and humiliating light; that as a result of it the husband acquires almost a genuine and strong affection for the girl who is the cause of the quarrel; and finally that, even though he is compelled, for the time at all events, to yield to his wife, he remains at the end exactly what he was at the beginning. Nor had husband or wife the very slightest wish to leave each other; the bond of marriage remained firm, but it had been degraded by insincerity on one side and the jealous endeavor on the other to secure fidelity by compulsion.

Apart altogether, however, from the question of its effectiveness, or even of the misery that it causes to all concerned, it is evident that jealousy is incompatible with all the tendencies of civilization. We have seen that a certain degree of variation is involved in the sexual relationship, as in all other relationships, and unless we are to continue to perpetuate many evils and injustices, that fact has to be faced and recognized. We have also seen that the line of our advance involves a constant increase in moral responsibility and self-government, and that, in its turn, implies not only a high degree of sincerity but also the recognition that no person has any right, or indeed any power, to control the emotions and actions of another person. If our sun of love stands still at midday, according to Ellen Key's phrase, that is a miracle to be greeted with awe and gratitude, and by no means a right to be demanded. The claim of jealousy falls with the claim of conjugal rights.

It is quite possible, Bloch remarks (The Sexual Life of Our Time, Ch. X), to love more than one person at the same time, with nearly equal tenderness, and to be honestly able to assure each of the passion felt for her or him. Bloch adds that the vast psychic differentiation involved by modern civilization increases the possibility of this double love, for it is difficult for anyone to find his complement in a single person, and that this applies to women as well as to men.

Georg Hirth likewise points out (Wege zur Heimat, pp. 543-552) that it is important to remember that women, as well as men, can love two persons at the same time. Men flatter themselves, he remarks, with the prejudice that the female heart, or rather brain, can only hold one man at a time, and that if there is a second man it is by a kind of prostitution. Nearly all erotic writers, poets, and novelists, even physicians and psychologists, belong to this class, he says; they look on a woman as property, and of course two men cannot "possess" a woman. (Regarding novelists, however, the remark may be interpolated that there are many exceptions, and Thomas Hardy, for instance, frequently represents a woman as more or less in love with two men at the same time.) As against this desire to depreciate women's psychic capacity, Hirth maintains that a woman is not necessarily obliged to be untrue to one man because she has conceived a passion for another man. "Today," Hirth truly declares, "only love and justice can count as honorable motives in marriage. The modern man accords to the beloved wife and life-companion the same freedom which he himself took before marriage, and perhaps still takes in marriage. If she makes no use of it, as is to be hoped—so much the better! But let there be no lies, no deception; the indispensable foundation of modern marriage is boundless sincerity and friendship, the deepest trust, affectionate devotion, and consideration. This is the best safeguard against adultery.... Let him, however, who is, nevertheless, overtaken by the outbreak of it console himself with the undoubted fact that of two real lovers the most noble-minded and deep-seeing friend will always have the preference." These wise words cannot be too deeply meditated. The policy of jealousy is only successful—when it is successful—in the hands of the man who counts the external husk of love more precious than the kernel.

It seems to some that the recognition of variations in sexual relationships, of the tendency of the monogamic to overpass its self-imposed bounds, is at best a sad necessity, and a lamentable fall from a high ideal. That, however, is the reverse of the truth. The great evil of monogamy, and its most seriously weak point, is its tendency to self-concentration at the expense of the outer world. The devil always comes to a man in the shape of his wife and children, said Hinton. The family is a great social influence in so far as it is the best instrument for creating children who will make the future citizens; but in a certain sense the family is an anti-social influence, for it tends to absorb unduly the energy that is needed for the invigoration of society. It is possible, indeed, that that fact led to the modification of the monogamic system in early developing periods of human history, when social expansion and cohesion were the primary necessities. The family too often tends to resemble, as someone has said, the secluded collection of grubs sometimes revealed in their narrow home when we casually raise a flat stone in our gardens. Great as are the problems of love, and great as should be our attention to them, it must always be remembered that love is not a little circle that is complete in itself. It is the nature of love to irradiate. Just as family life exists mainly for the social end of breeding the future race, so family love has its social ends in the extension of sympathy and affection to those outside it, and even in ends that go beyond love altogether.[[417]]

The question is debated from time to time as to how far it is possible for men and women to have intimate friendships with each other outside the erotic sphere.[[418]] There can be no doubt whatever that it is perfectly possible for a man and a woman to experience for each other a friendship which never intrudes into the sexual sphere. As a rule, however, this only happens under special conditions, and those are generally conditions which exclude the closest and most intimate friendship. If, as we have seen, love may be defined as a synthesis of lust and friendship, friendship inevitably enters into the erotic sphere. Just as sexual emotion tends to merge into friendship, so friendship between persons of opposite sex, if young, healthy, and attractive, tends to involve sexual emotion. The two feelings are too closely allied for an artificial barrier to be permanently placed between them without protest. Men who offer a woman friendship usually find that it is not received with much satisfaction except as the first installment of a warmer emotion, and women who offer friendship to a man usually find that he responds with an offer of love; very often the "friendship" is from the first simply love or flirtation masquerading under another name.

"In the long run," a woman writes (in a letter published in Geschlecht und Gesellschaft, Bd. i, Heft 7), "the senses become discontented at their complete exclusion. And I believe that a man can only come into the closest mutual association with a woman by whom, consciously or unconsciously, he is physically attracted. He cannot enter into the closest psychic intercourse with a woman with whom he could not imagine himself in physical intercourse. His prevailing wish is for the possession of a woman, of the whole woman, her soul as well as her body. And a woman also cannot imagine an intimate relation to a man in which the heart and the body, as well as the mind, are not involved. (Naturally I am thinking of people with sound nerves and healthy blood.) Can a woman carry on a Platonic relation with a man from year to year without the thought sometimes coming to her: 'Why does he never kiss me? Have I no charm for him?' And in the most concealed corner of her heart will it not happen that she uses that word 'kiss' in the more comprehensive sense in which the French sometimes employ it?" There is undoubtedly an element of truth in this statement. The frontier between erotic love and friendship is vague, and an intimate psychic intercourse that is sternly debarred from ever manifesting itself in a caress, or other physical manifestation of tender intimacy, tends to be constrained, and arouses unspoken and unspeakable thoughts and desires which are fatal to any complete friendship.

Undoubtedly the only perfect "Platonic friendships" are those which have been reached through the portal of a preliminary erotic intimacy. In such a case bad lovers, when they have resolutely traversed the erotic stage, may become exceedingly good friends. A satisfactory friendship is possible between brother and sister because they have been physically intimate in childhood, and all erotic curiosities are absent. The most admirable "Platonic friendship" may often be attained by husband and wife in whom sympathy and affection and common interests have outlived passion. In nearly all the most famous friendships of distinguished men and women—as we know in some cases and divine in others—an hour's passion, in Sainte-Beuve's words, has served as the golden key to unlock the most precious and intimate secrets of friendship.[[419]]

The friendships that have been entered through the erotic portal possess an intimacy and retain a spiritually erotic character which could not be attained on the basis of a normal friendship between persons of the same sex. This is true in a far higher degree of the ultimate relationship, under fortunate circumstances, of husband and wife in the years after passion has become impossible. They have ceased to be passionate lovers but they have not become mere friends and comrades. More especially their relationship takes on elements borrowed from the attitude of child to parent, of parent to child. Everyone from his first years retains something of the child which cannot be revealed to all the world; everyone acquires something of the guardian paternal or maternal spirit. Husband and wife are each child to the other, and are indeed parent and child by turn. And here still the woman retains a certain erotic supremacy, for she is to the last more of a child than it is ever easy for the man to be, and much more essentially a mother than he is a father.

Groos (Der Æsthetische Genuss, p. 249) has pointed out that "love" is really made up of both sexual instinct and parental instinct.
