You may have noticed that the books you really love are bound together by a secret thread. You know very well what is the common quality that makes you love them, though you cannot put it into words: but most of your friends do not see it at all, and often wonder why, liking this, you should also like that. Again, you have stood before some landscape, which seems to embody what you have been looking for all your life; and then turned to the friend at your side who appears to be seeing what you saw -- but at the first words a gulf yawns between you, and you realise that this landscape means something totally different to him, that he is pursuing an alien vision and cares nothing for the ineffable suggestion by which you are transported. Even in your hobbies, has there not always been some secret attraction which the others are curiously ignorant of -- something, not to be identified with, but always on the verge of breaking through, the smell of cut wood in the workshop or the clap-clap of water against the boat's side? Are not all lifelong friendships born at the moment when at last you meet another human being who has some inkling (but faint and uncertain even in the best) of that something which you were born desiring, and which, beneath the flux of other desires and in all the momentary silences between the louder passions, night and day, year by year, from childhood to old age, you are looking for, watching for, listening for? You have never had it. All the things that have ever deeply possessed your soul have been but hints of it -- tantalising glimpses, promises never quite fulfilled, echoes that died away just as they caught your ear. But if it should really become manifest -- if there ever came an echo that did not die away but swelled into the sound itself -- you would know it. Beyond all possibility of doubt you would say "Here at last is the thing I was made for". We cannot tell each other about it. It is the secret signature of each soul, the incommunicable and unappeasable want, the thing we desired before we met our wives or made our friends or chose our work, and which we shall still desire on our deathbeds, when the mind no longer knows wife or friend or work. While we are, this is. If we lose this, we lose all.
It is part of the nature of a strong erotic passion—as distinct from a transient fit of appetite—that makes more towering promises than any other emotion. No doubt all our desires makes promises, but not so impressively. To be in love involves the almost irresistible conviction that one will go on being in love until one dies, and that possession of the beloved will confer, not merely frequent ecstasies, but settled, fruitful, deep-rooted, lifelong happiness. Hence all seems to be at stake. If we miss this chance we shall have lived in vain. At the very thought of such a doom we sink into fathomless depths of self-pity.Unfortunately these promises are found often to be quite untrue. Every experienced adult knows this to be so as regards all erotic passions (except the one he himself is feeling at the moment). We discount the world-without-end pretensions of our friends’ amours easily enough. We know that such things sometimes last—and sometimes don’t. And when they do last, this is not because they promised at the outset to do so. When two people achieve lasting happiness, this is not solely because they are great lovers but because they are also—I must put it crudely—good people; controlled, loyal, fair-minded, mutually adaptable people.If we establish a “right to (sexual) happiness” which supersedes all the ordinary rules of behavior, we do so not because of what our passion shows itself to be in experience but because of what it professes to be while we are in the grip of it.
