The only seeming objection of much weight that can be brought against diffusing a knowledge of checks is, that it will serve to increase illegal connections. Now, this is exactly the contrary effect of that which those who have diffused such knowledge most confidently believe will arise from it. To diminish such connections is indeed one of the grand objects of this publication,--an object which laws and prisons cannot, or, at least, do not, accomplish. Why is there so much prostitution in the land? The true answer to the question is not, and never will be, Because the people have become acquainted with certain facts in physiology; it is because there are so many unmarried men and women,--men of dissipation and profligacy, owing to their not having married in their younger days and settled down in life. But why are there so many unmarried people in the country? Not because young hearts when they arrive at the age of maturity do not desire to marry; but because prudential considerations interfere. The young man thinks: I cannot marry yet; I cannot support a family; I must make money first, and think of a matrimonial settlement afterward. And so it is, that through fear of having a family, before they have made a little headway in the world, and of being thereby compelled to "tug at the oar of incessant labor throughout their lives," thousands of young men do not marry, but go abroad into the world and form vicious acquaintances and practices. The truth, then, is this,--there is so much illegal connection in the land, because the people had not, twenty years ago, that very information which, it would seem, some, doubtless through want of due reflection, are apprehensive will increase this evil. I might quote pages to the point from "Every Woman's Book," but I fear my communication would be too lengthy. I content myself with a few lines. "But when it has become the custom here as elsewhere to limit the number of children, so that none need have more than they wish, no man will fear to take a wife; all will marry while young; debauchery will diminish; while good morals and religious duties will be promoted." It has been asked if a general knowledge of checks would not diminish the general increase of population? I think that such would not be the result in this country until such result would be desirable. In my opinion the effect would be a good many more families (and, on the whole, as many births), but not so many overgrown and poverty-stricken ones. It has been said, It is better to let Nature take her course. Now, in the broadest sense of the word "Nature," I say so too. In this sense there is nothing unnatural in the universe. But if we limit the sense of the word Nature so as not to include what we mean by art, then is civilized life one continued warfare against Nature. It is by art that we subdue the forest; by art we contend against the elements; by art we combat the natural tendency of disease, etc.
