The mortality, and potential misery, of Eros (unless supported by higher love):
And all the time the grim joke is that this Eros whose voice seems to speak from the eternal realm is not himself necessarily even permanent. He is notoriously the most mortal of our loves. The world rings with complaints of his fickleness. What is baffling is the combination of this fickleness with his protestations of permanency. To be in love is both to intend and to promise lifelong fidelity. Love makes vows unasked; can’t be deterred from making them. “I will be ever true,” are almost the first words he utters. Not hypocritically but sincerely. No experience will cure him of the delusion. We have all heard of people who are in love again every few years; each time sincerely convinced that “this time it’s the real thing,” that their wanderings are over, that they have found their true love and will themselves be true till death.
And yet Eros is in a sense right to make this promise. The event of falling in love is of such a nature that we are right to reject as intolerable the idea that it should be transitory. In one high bound it has overleaped the massive wall of our selfhood; it has made appetite itself altruistic, tossed personal happiness aside as a triviality and planted the interests of another in the centre of our being. Spontaneously and without effort we have fulfilled the law (towards one person) by loving our neighbour as ourselves. It is an image, a foretaste, of what we must become to all if Love Himself rules in us without a rival. It is even (well used) a preparation for that. Simply to relapse from it, merely to “fall out of” love again, is—if I may coin the ugly word—a sort of disredemption. Eros is driven to promise what Eros of himself cannot perform.
Can we be in this selfless liberation for a lifetime? Hardly for a week. Between the best possible lovers this high condition is intermittent. The old self soon turns out to be not so dead as he pretended—as after a religious conversion. In either he may be momentarily knocked flat; he will soon be up again; if not on his feet, at least on his elbow, if not roaring, at least back to his surly grumbling or his mendicant whine. …
But these lapses will not destroy a marriage between two “decent and sensible” people. The couple whose marriage will certainly be endangered by them, and possibly ruined, are those who have idolised Eros. They thought he had the power and truthfulness of a god. They expected that mere feeling would do for them, and permanently, all that was necessary. When this expectation is disappointed they throw the blame on Eros or, more usually, on their partners. In reality, however, Eros, having made his gigantic promise and shown you in glimpses what its performance would be like, has “done his stuff.” He, like a godparent, makes the vows; it is we who must keep them. It is we who must labour to bring our daily life into even closer accordance with what the glimpses have revealed. We must do the works of Eros when Eros is not present. This all good lovers know …
Thus Eros, like the other loves, but more strikingly because of his strength, sweetness, terror and high port, reveals his true status. He cannot of himself be what, nevertheless, he must be if he is to remain Eros. He needs help; therefore needs to be ruled. The god dies or becomes a demon unless he obeys God. It would be well if, in such case, he always died. But he may live on, mercilessly chaining together two mutual tormentors, each raw all over with the poison of hate-in-love, each ravenous to receive and implacably refusing to give, jealous, suspicious, resentful, struggling for the upper hand, determined to be free and to allow no freedom.
