The case is different as regards those individuals or classes who are immediately occupied with the technique and manual operations of production.

Their daily life is not in the same degree a course of habituation to the emulative and invidious motives and maneuvers of the pecuniary side of industry.

They are consistently held to the apprehension and coordination of mechanical facts and sequences, and to their appreciation and utilization for the purposes of human life.

So far as concerns this portion of the population, the educative and selective action of the industrial process with which they are immediately in contact acts to adapt their habits of thought to the non-invidious purposes of the collective life.

For them, therefore, it hastens the obsolescence of the distinctively predatory aptitudes and propensities carried over by heredity and tradition from the barbarian past of the race.
The educative action of the economic life of the community, therefore, is not of a uniform kind throughout all its manifestations.
