One may as well consider these two facts as one and the same fact, namely, the manifoldness of nature which makes the universe a complex of infinite varieties. The division of labor is the outcome of man's conscious reaction to the multiplicity of natural conditions. On the other hand, it is itself a factor bringing about differentiation. It assigns to the various geographic areas specific functions in the complex of the processes of production. Still more important, however, is the fact that it intensifies the innate inequality of men.
Vocational types emerge, people become specialists.
The division of labor splits the various processes of production into minute tasks, many of which can be performed by mechanical devices. It is this fact that made the use of machinery possible and brought about the amazing improvements in technical methods of production. Mechanization is the fruit of the division of labor, its most beneficial achievement, not its motive and fountain spring. Power-driven specialized machinery could be employed only in a social environment under the division of labor. Every step forward on the road toward the use of more specialized, more refined, and more productive machines requires a further specialization of tasks.
