This kind of objection applies in a marked degree to birth-control which challenges people’s most intimate habits, and seems likely to effect a revolution in their conduct. It will, however, diminish as the idea of birth-control becomes familiar. The reaction of the normal Englishman to that which is new usually passes through three phases. He says first “It is absurd”, second “It is contrary to Scripture”, and third “Of course! I knew it all the time”. It will be seen that the opposition to birth-control has already passed into the second phase. There is a further reason for the probable weakening of the anti-birth-control movement. The organized opposition to birth-control comes very largely from members of the upper and middle classes. These on an average have very much smaller families than the lower classes in whose interests they profess to oppose birth-control, and to whom they denounce it. The inevitable inference from this fact cannot continue indefinitely to remain undrawn, and, as soon as it is drawn, the lower classes will be able to gauge the sincerity of those who exhort them to choose between continence or children, while being themselves remarkable for neither. Finally the knowledge of the use of contraceptives is bound in course of time to percolate through every social stratum. The advantages of birth-control to the individual are so obvious that few will refuse to avail themselves of the knowledge which the State, in the persons of the medical officers in charge of infant welfare centres, at present withholds; while the disadvantages to the community of a system under which the lower strata proliferate unchecked, while the upper and middle classes barely keep up their numbers, and the exceptional man who has the talent and energy to climb from one stratum into another finds it necessary to sterilize himself in the process, will, in the shape of a rapidly deteriorating population, force themselves upon the notice of even the most pious. Birth-control has come to stay; it has also knocked the bottom out of what is called sexual morality.
