For what, if it comes to that, does a man choose? Here is Herbert Spencer's reply to that question:--"The truth is that out of the many elements uniting in various proportions, to produce in a man's breast the complex emotion we call love, the strongest are those produced by physical attractions; the next in order of strength are those produced by moral attractions; the weakest are those produced by intellectual attractions; and even these are dependent less on acquired knowledge than on natural faculty--quickness, wit, insight." It will probably be agreed that, on the whole, this analysis, which is certainly true in the direction it refers to, is also true in the converse direction. The girl admires a man for physical qualities, including what may be called the physical virtues, like energy and courage. She rates highly certain moral attractions, such as unselfishness and chivalry, but perhaps she attaches far more value to intellectual attractions than the man does in her case, doubtless because they are more distinctively masculine. No doubt, in this order of importance both sexes are consulting the eugenic end if they knew it, as Spencer, indeed, pointed out nearly half a century ago. The passage from which we have quoted he thus continues:-- "If any think the assertion a derogatory one, and inveigh against the masculine character for being thus swayed, we reply that they little know what they say when they thus call in question the Divine ordinations. Even were there no obvious meaning in the arrangement, we may be sure that some important end was subserved. But the meaning is quite obvious to those who examine. When we remember that one of Nature's ends, or rather her supreme end, is the welfare of posterity; further that, in so far as posterity are concerned, a cultivated intelligence based on a bad physique is of little worth, since its descendants will die out in a generation or two: and conversely that a good _physique_, however poor the accompanying mental endowments, is worth preserving, because, throughout future generations, the mental endowments may be indefinitely developed; we perceive how important is the balance of instincts above described."
