Half-a-dozen problems of extreme national importance confront every thinking English man and woman in 1907. The air is thick with their stir and movement, and so great is the noise and reverberation of them that true “royalty” of “_inward_ happiness” seems a thing impossible and past by in these troubled times. Be that as it may, it is quite certain that one of the most real and pressing of these problems is that summed up in the stock phrase “Record Low Birth-rate.” We hear a great deal about the doings of a class of people who are referred to as “The Smart Set,” and it is actually said that its influence is having a serious effect upon the national character. I do not believe it for a moment. It seems a folly to suppose that a handful of champagne corks floating on a cess-pool has any far-reaching influence upon the English home. I mention that small section of society constituted by the idle and luxurious rich, because, whatever their vices are, they are being used as whipping-boy for enormous numbers of people whose lives are equally guilty with theirs in at least one regard--in the matter of which I am writing now. I propose in this essay to discuss the question of the decline in the birth-rate from the Christian and Catholic standpoint. There is only one perfect philosophy, and all other half-true philosophies in the light of which we might consider such a momentous matter as this, lead only to the conclusion that expediency is the highest good. Without the incentive of the Christian Faith and without the light of the Incarnation one may sit in a corner and think till “all’s blue in cloud cuckoo land.” Christianity can alone be reconciled with Economics, theory and practice celebrating always the marriage of the King’s son, the wedding of Heaven and Earth, the spiritual and the material. Plato knew that it was impossible to raise the Greek state to the level of his philosophic principles, and Aristotle frankly abandons the attempt to connect ethics and politics with the highest conclusions of his creed. We are in the same position to-day if we ignore the supreme truth which is our possession and which was not vouchsafed to the great Greek thinkers. * * * * * There is one cause and one cause only of the decline in the birth-rate and the beginning of the country’s spiritual and material suicide. The way of Nature is for every species to increase nearly to its possible maximum of numbers. This is a proved law, and nothing but the limitation of families by artificial means, or infanticide, can check its operation. The truth is exactly as Dr. Barry put it nearly two years ago, “It stands confessed that the great, proud, English race, famous as a people for manly virtues, once the very Stoics of Christian Europe decline more and more to be fathers and mothers, will not be worried with children, and--cannot be spoken of in decent language.”
