It must be insisted again that this question has many ramifications, and that not the least important of them are those which concern themselves with the kinds of disease already referred to. Some enemy of God and man once invented a phrase about the desirability of young men sowing their wild oats, and subsequent enemies of life and the good and progress, or perhaps mere fools, animated gramophones of a cheap pattern, have repeated and still propagate that doctrine. It is poisonous to its core; it never did any one any good, and has done incalculable harm. It has blinded the eyes of hundreds of thousands of babies; it has brought hundreds of thousands more rotten into the world. Hosts of dead men, women, and children are its victims. It is indeed good that a man should be a man, and not a worm on stilts; it is indeed good that women should prefer men to be men, and that as soon as possible they should cease to accept in marriage the feeble, the cowardly, the echoers, and the sheep. But this is a very different thing from asserting that it is good for young men, before marriage, to adopt a standard of morality which would be thought shameful beyond words in their sisters, and which has all the horrible consequences that have been alluded to, and many more. Now, vicious though the wild oats doctrine be in itself and in its consequences, we have to grant that there is little need of it, for young manhood needs the insertion of no doctrines from without to encourage it towards the satisfaction of what are in themselves natural and healthy tendencies. Our right procedure therefore should be--notwithstanding the unhealthy tendency of high civilization in this respect, and notwithstanding the terrible folly, traitorous to their sex, of those women who decry marriage, and seek to delay it--to prepare girlhood and public opinion, and even to modify, so far as may be necessary, economic conditions, in order that the girls who are worthy to marry at all shall do so at the right age, and shall join themselves for life with rightly chosen men. One more point may be conveniently considered here, though it is not strictly a matter of the marriage age for girls. The point is as to the most generally desirable age relation between husband and wife. Here, again, we must remind ourselves that it is impossible to lay down the law for any case, and that that is not what we are now attempting to do. As every one knows, there is an average disparity of some few years in the ages of husband and wife. This may be referred probably to economic conditions in part, and also to the fact that girlhood becomes womanhood at a somewhat earlier age than boyhood becomes manhood. The girl is more precocious. Thus though she be twenty and her husband twenty-three, she is as mature.
