Seeing the ease and security in which these people were living, I felt that this close resemblance of the sexes was after all what one would expect; for the strength of a man and the softness of a women, the institution of the family, and the differentiation of occupations were mere militant necessities of an age of physical force; where population is balanced and abundant, much child-bearing becomes and evil rather than a blessing to the State; where violence comes but rarely and off-spring are secure, there is less necessity - indeed there is no necessity - for an effective family, and the specialization of the sexes with reference to their children's needs disappears. We see some beginnings of this even in our own time, and i this future age, it was complete.
