In our quotation from Herbert Spencer we may notice the significant assertion that amongst intellectual attractions it is natural faculty, quickness, wit and insight, rather than acquired knowledge, that a man admires in a woman. In considering that point the somewhat hazardous assertion was ventured upon that the woman rates intellectual attractions in the man higher than he does in her. One has indeed heard it stated that a man marries for beauty and a woman for brains. A statement so brief cannot be accurate in such a case. But we may insist upon the contrast between acquired knowledge and natural faculty. Spencer was no doubt right in believing that man values the natural faculty rather than the acquired knowledge. A woman no doubt does so too. If she admires a man for being an encyclopaedia, it is only, one hopes, because she admires the natural qualities of studiousness, perseverance and memory which his knowledge involves. Nor would she be long in finding out whether his knowledge is digested, and the capacity to digest it, remember, is a natural faculty. The reader who remembers our principle that the individual exists for the future will not fail to see what we are driving at. Directly we study in any critical way the causes of attraction among the sexes, we see that under healthy conditions, unvitiated by convention or money, it is always the inborn rather than the acquired that counts. If Spencer had cared to pursue his point half a century ago, he had the key to it in his hands. Youth prefers the natural to the acquired qualities. Nature, greatest of match-makers, has so constructed youth because she is a Eugenist, and because she knows that it is the natural qualities and not the acquired ones which are transmitted to offspring.
