Abstract
This is one of the four articles criticizing the theories in which the origin of the sociological theory of the family is dated from 1861.
In this article tne writer takes up Justus Moser and explains how he rejected the Katastrophentheorie which was most prevailing in those days and how he attempted to reproduce the old Germanic days on the basis of the realities he witnessed in Westphalia, especially in Osnabrück, where the Roman influence was comparatively less evident.
The writer also refers to Möser's contributions concerning the studies of the family, including the Einzelhoftheorie, as well as to his view on inheritance, which, in spite of the criticism by Brentano, L., still may well be re-appreciated in some respects.
