The family is an early expedient and in many ways irrational. If the race had developed a special sexless class to be nurses, pedagogues, and slaves, like the workers among ants and bees, then the family would have been unnecessary. Such a division of labor would doubtless have involved evils of its own, but it would have obviated some drags and vexations proper to the family.
