I didn't leave New York; I lacked the energy. I just mooned around the city for a while, avoiding my friends, and dreaming of the impossible beauty of the face in the mirror. And by and by the longing to see that vision of perfection once more began to become overpowering. I don't suppose anyone except me can understand the lure of that memory; the face, you see, had been my ideal, my concept of perfection. One sees beautiful women here and there in the world; one falls in love, but always, no matter how great their beauty or how deep one's love, they fall short in some degree of the secret vision of the ideal. But not the mirrored face; she was my ideal, and therefore, whatever imperfections she might have had in the minds of others, in my eyes she had none. None, that is, save the terrible one of being only an ideal, and therefore unattainable--but that is a fault inherent in all perfection. It was a matter of days before I yielded. Common sense told me it was futile, even foolhardy, to gaze again on the vision of perfect desirability. I fought against the hunger, but I fought hopelessly, and was not at all surprised to find myself one evening rapping on van Manderpootz's door in the University Club. He wasn't there; I'd been hoping he wouldn't be, since it gave me an excuse to seek him in his laboratory in the Physics Building, to which I would have dragged him anyway. There I found him, writing some sort of notations on the table that held the idealizator. "Hello, Dixon," he said. "Did it ever occur to you that the ideal university cannot exist? Naturally not since it must be composed of perfect students and perfect educators, in which case the former could have nothing to learn and the latter, therefore, nothing to teach." What interest had I in the perfect university and its inability to exist? My whole being was desolate over the non-existence of another ideal. "Professor," I said tensely, "may I use that--that thing of yours again? I want to--uh--see something." My voice must have disclosed the situation, for van Manderpootz looked up sharply. "So!" he snapped. "So you disregarded my advice! Forget her, I said. Forget her because she doesn't exist." "But--I can't! Once more, Professor--only once more!"
