“This is the basic theme of family and civilisation. Civilization grows out of familism; as it grows it loses its original connection with the basic spring which furnished the essence of civilization. When this process has gone too far, the civilization soon exhausts its inventory of social ‘material’. Then occurs a reaction or decay. The amount of reaction and decay and the length of these ‘Dark Age’ periods seem to depend upon how quickly the culture finds its way back to the fundamental mothersource – familism.”
