It will now perhaps be clear how it is that the eugenic conception of the improvement of the race embodies a new ideal. We are familiar with legislative projects for compulsory certificates as a condition of marriage. But even apart from all the other considerations which make such schemes both illusory and undesirable, these externally imposed regulations fail to go to the root of the matter. If they are voluntary, if they spring out of a fine eugenic aspiration, it is another matter. Under these conditions the method may be carried out at once. Professor Grasset has pointed out one way in which this may be effected. We cannot, he remarks, follow the procedure of a military _conseil de revision_ and compulsorily reject the candidate for a definite defect. But it would be possible for the two families concerned to call a conference of their two family doctors, after examination of the would-be bride and bridegroom, permitting the doctors to discuss freely the medical aspects of the proposed union, and undertaking to accept their decision, without asking for the revelation of any secrets, the families thus remaining ignorant of the defect which prevented this union but might not prevent another union, for the chief danger in many cases comes from the conjunction of convergent morbid tendencies.[160] In France, where much power remains with the respective families, this method might be operative, provided complete confidence was felt in the doctors concerned. In some countries, such as England, the prospective couple might prefer to take the matter into their own hands, to discuss it frankly, and to seek medical advice on their own account; this is now much more frequently done than was formerly the case. But all compulsory projects of this kind, and indeed any mere legislation, cannot go to the root of the matter. For in the first place, what we need is a great body of facts, and a careful attention to the record and registration and statistical tabulation of personal and family histories. In the second place, we need that sound ideals and a high sense of responsibility should permeate the whole community, first its finer and more distinguished members and then, by the usual contagion that rules in such matters, the whole body of its members.[161] In time, no doubt, this would lead to concerted social action. We may reasonably expect that a time will come when if, for instance, an epileptic woman conceals her condition from the man she is marrying it would generally be felt that an offence has been committed serious enough to invalidate the marriage. We must not suppose that lovers would be either willing or competent to investigate each other's family and medical histories. But it would be at least as easy and as simple to choose a partner from those persons who had successfully passed the eugenic test--more especially since such persons would certainly be the most attractive group in the
