While the developing society has thus become integrated, it has passed from its original uniform state into a multiform state. Among savages there are no unlikenesses of occupations. Every man is hunter and upon occasion warrior; every man builds his own hut, makes his own weapons; every wife digs roots, catches fish, and carries the household goods when a change of locality is needed: what division of labor exists is only between the sexes. We all know that it is quite otherwise with a civilized nation. The changes which have produced the coherence have done this by producing the division of labor: the two going on _pari passu_. The great parts and the small parts, and the parts within parts, into which a modern society is divisible, are clusters of men made unlike in so far as they discharge the unlike functions required for maintaining the national life. Rural laborers and farmers, manufacturers and their workpeople, wholesale merchants and retailers, etc., etc., constitute differentiated groups, which make a society as a whole extremely various in composition. Not only in its industrial divisions is it various, but also in its governmental divisions, from the components of the legislature down through the numerous kinds and grades of officials, down through the many classes of masters and subordinates, down through the relations of shopkeeper and journeyman, mistress and maid. That is to say, the change which has been taking place is, under one aspect, a change from homogeneity of the parts to heterogeneity of the parts.
