It is human experience that as a man concentrates his efforts, either mental or manual, his skill in his chosen specialty, and the quantity of his product increase. It was shown... that specialization in machinery had a powerful influence in specializing the workman and thereby extending the principle of division of labor.

He must be content to cultivate a small portion of it. (en) |
