Imagine a young man in good health and easy circumstances, entirely ripe for love. The prompting to mate and beget arises within his interstitial depths, traverses his lymphatic system, lifts his blood pressure, and goes whooping through his _meatus auditorium externus_ like a fanfare of slide trombones. The impulse is very powerful. It staggers and dismays him. He trembles like a stag at bay. Why, then, doesn't he fall head over heels in love with the first eligible woman that he meets? For the plain reason that the majority of women that he meets offend him, repel him, disgust him. Often it is in some small, inconspicuous and, at first glance, unanalyzable way. She is, in general, a very pretty girl--but her ears stand out too much. Or her hair reminds him of oakum. Or her mouth looks like his aunt's. Or she has beer-keg ankles. Here very impalpable things, such as bodily odors, play a capital part; their importance is always much underestimated. Many a girl has lost a husband by using the wrong perfume, or by neglecting to have her hair washed. Many another has come to grief by powdering her nose too much or too little, or by shrinking from the paltry pain of having some of her eyebrows pulled, or by employing a lip-salve with too much purple in it, or by patronizing a bad dentist, or by speaking incautiously of chilblains.... But eventually the youth finds his love--soon or late the angel foreordained comes along. Who is this prodigy? Simply the _first_ girl to sneak over what may be called the threshold of his disgusts--simply the _first_ to disgust him so little, at first glance, that the loud, insistent promptings of the Divine Schadchen have a chance to be heard. If he muffs this first, another will come along, maybe soon, maybe late. For every normal man there are hundreds of thousands in Christendom, thousands in his own town, scores within his own circle of acquaintance. This normal man is not too delicate. His fixed foci of disgust are neither very numerous nor very sensitive. For the rest, he is swayed by fashion, by suggestion, by transient moods. Anon a mood of cynicism is upon him and he is hard to please, but anon he succumbs to sentimentality and is blind to everything save the grossest offendings. It is only the man of extraordinary sensitiveness, the man of hypertrophied delicacy, who must search the world for his elective affinity.
