The love of man and woman is, no doubt, a thing of infinite importance; but also of infinite importance is the manner in which woman earns her bread and the economic conditions under which she enters the family and propagates the race. Thus an inquiry into the circumstances under which the wife and mother plies her trade seems to me quite as necessary and justifiable as an inquiry into the conditions of other and less important industriessuch as mining or cotton-spinning. It will not be disputed that the manner in which a human being earns his livelihood tends to mould and influence his characterto warp or to improve it. The man who works amidst brutalizing surroundings is apt to become brutal; the man from whom intelligence is demanded is apt to exercise it. Particular trades tend to develop particular types; the boy who becomes a soldier will not turn out in all respects the man he would have been had he decided to enter a stockbroker's office. In the same way the trade of marriage tends to produce its own particular type, and my contention is that woman, as we know her, is largely the product of the conditions imposed upon her by her staple industry.
