This male tendency is seen taking selfish and brutal forms in the social life of the community. For instance, when the responsibility that the birth of a daughter places upon the family has induced such a custom as the killing of female children at birth, a custom found in many different countries at different times; or when, as now in Western civilization, even among the wealthy, parents restrict their families and take means to prevent the birth of any child, male or female, through dread of responsibility. Again, the natural dependence of woman is often greatly increased by man; for so strong is the feeling that a man's responsibilities in life are greater than hers, since he bears hers as well as his own, that woman is deprived in order that he may have every advantage that offers. In order that he may be better fitted for his fight in the world, her natural disabilities are added to and increased.
