It is not the purpose of the present chapter to deal with that which must be said, notwithstanding prudery, and in order that the price of prudery shall no longer be paid. But one final principle may be laid down which is indeed perhaps merely an expression of the spirit underlying the foregoing remarks upon our terminology. It is that we are to fly our flag high. We may consult Mrs. Grundy's prejudices if we find that in doing so we may directly serve our own thinking, and therefore our cause. This is very different from any kind of apologizing to her. All such I utterly deplore. We must not begin by granting Mrs. Grundy's case in any degree. Somewhere in that chaos of prejudices which she calls her mind, she nourishes the notion, common to all the false forms of religion, ancient or modern, that there is something about sex and parenthood which is inherently base and unclean. The origin of this notion is of interest, and the anthropologists have devoted much attention to it. It is to be found intermingled with a by no means contemptible hygiene in the Mosaic legislation, is to be traced in the beliefs and customs of extant primitive peoples, and has formed and forms an element in most religions. But it is not really pertinent to our present discussion to weigh the good and evil consequences of this belief. Without following the modern fashion, prevalent in some surprising quarters, of ecstatically exaggerating the practical value of false beliefs in past and present times, we may admit that the cause of morality in the humblest sense of that term may sometimes have been served by the religious condemnation of all these matters as unclean, and of parenthood as, at the best, a second best.
