"When a contraceptive method is adopted under satisfactory conditions, with a due regard to the requirements of the individual couple, there is little room to fear that any injurious results will be occasioned. It is quite true that many physicians speak emphatically concerning the injurious results to husband or to wife of contraceptive devices. Although there has been exaggeration, and prejudice has often been imported into this question, and although most of the injurious results could have been avoided had trained medical help been at hand to advise better methods, there can be no doubt that much that has been said under this head is true. Considering how widespread is the use of these methods, and how ignorantly they have often been carried out, it would be surprising indeed if it were not true. But even supposing that the nervously injurious effects which have been traced to contraceptive practices were a thousandfold greater than they have been reported to be--instead of, as we are justified in believing, considerably less than they are reported--shall we therefore condemn contraceptive methods? To do so would be to ignore all the vastly greater evils which have followed in the past from unchecked reproduction. It would be a condemnation which, if we exercised it consistently, would destroy the whole of civilization and place us back in savagery. For what device of man, ever since man had any history at all, has not proved sometimes injurious? "Every one of even the most useful and beneficial of human inventions has either exercised subtle injuries or produced appalling catastrophes. This is not only true of man's devices, it is true of Nature's in general. Let us take, for instance, the elevation of man's ancestors from the quadrupedal to the bipedal position. The experiment of making a series of four-footed animals walk on their hind-legs was very evolutionary and risky; it was far more beset by dangers than is the introduction of contraceptives; we are still suffering all sorts of serious evils in consequence of Nature's action in placing our remote ancestors in the erect position. Yet we feel that it was worth while; even those physicians who most emphasize the evil results of the erect position do not advise that we should go on all-fours. It is just the same with a great human device, the introduction of clothes. They have led to all sorts of new susceptibilities to disease and even tendencies to direct injury of many kinds. Yet no one advocates the complete disuse of all clothing on the ground that corsets have sometimes proved harmful. It would be just as absurd to advocate the complete abandonment of contraceptives on the ground that some of them have been misused. If it were not, indeed, that we are familiar with the lengths to which ignorance and prejudice may go we should question the sanity of anyone who put forward so foolish a proposition. Every great step which Nature
