From an international equilibrium based upon a modification of religions as above suggested and upon an alteration in our standards of national evaluation, social harmony would follow fairly readily. It is unlikely that the antagonism between capital and labour will be much affected by a control of population beyond removing that source of social unrest which is furnished by a large body of unemployed. It remains doubtful, however, if the essential political issue will be much modified by a solution of the unemployment problem. The psychological forces which give the Labour party its driving power are not such as to produce the fullest economic prosperity in this country; but none the less they demand and must ultimately receive satisfaction. The best that can be hoped is that those forces will gradually be appeased, and will not lead to bloodshed, too great a dislocation of trade, or too drastic a loss of international status. The gain to the individual following the general application of knowledge of Birth Control will be twofold. In the first place parents will be able to space their children in accordance with their physical and financial resources; in the second they will feel more confident of producing healthy well-balanced children, untainted by disease, than they can feel at present. Their children would further be welcomed by the community, and their future would be assured. * * * * * Such are the bearings of an enlightened Birth Control upon the future. It is obvious that such advantages could only be gained by slow and laborious degrees. The writer is far from the opinion that the application of his views will immediately transform the world into a Utopia. He is convinced however that if the existing form of civilization is to have any permanence, the necessity for controlling population will have to be realized and striven for by all educated people. In practice, the ‘plea,’ referred to in the sub-title, is that the Ministry of Health should give the subject of contraception its sanction. In May of 1924 a petition supported by twenty-two Labour members of Parliament was presented to the Minister of Health by a deputation of eighteen persons, some of them well known, requesting that official permission be accorded to doctors in charge of Welfare Centres to give information on Birth Control to such working women as desired it and were considered fit for it. Though the existing technique is not wholly satisfactory it is avowedly worth something, having already proved of great help to many women.
