ABSTRACT
The fundamental stipulation for the existence of human society is the provision of means for such existence, in the first place food, then dwelling-place, clothing, weapons, tools and implements. The group of phenomena which they have to consider will embrace all that concerns those material means which are necessary for the maintenance and defence of individual life, and this group they may, in the widest sense, include under the name of social economy. Social economy, reproduction and social organization form a triangle which includes all life processes necessary for the existence of a social organism, that is, everything that is necessary for community of living beings. The authors adopt the method throughout, not only for chief divisions of the whole sphere of culture, but also for the subdivision of the sociological functions.
