THE AMERICAN JOURNAL OF SOCIOLOGY

Every device which facilitates trade and industry prepares the way for a further division of labor and so tends further to specialize the tasks in which men find their vocations.

The outcome of this process is to break down or modify the older organization of society, which was based on family ties, local associations, on culture, caste, and status, and to substitute for it an organization based on vocational interests.

In the city, every vocation, even that of a beggar, tends to assume the character of a profession, and the discipline which success in any vocation imposes, together with the associations that it enforces, emphasizes this tendency.

The effect of the vocations and the division of labor is to produce, in the first instance, not social groups, but vocational types, the actor, the plumber, and the lumber-jack. The organizations, like the trade and labor unions, which men of the same trade or profession form are based on common interests. In this respect they differ from forms of association like the neighborhood, which are based on contiguity, personal association, and the common ties of humanity. The different trades and professions seem disposed to group themselves in classes, that is to say, the artisan, business, and professional classes. But in the modern democratic state the classes have as yet attained no effective organization. Socialism, founded on an effort to create an organization based on "class consciousness," has never succeeded in creating more than a political party.

The effects of the division of labor as a discipline may therefore be best studied in the vocational types it has produced.

Among the types which it would be interesting to study are: the shopgirl, the policeman, the peddler, the cabman, the night watchman, the clairvoyant, the vaudeville performer, the quack doctor, the bartender, the ward boss, the strike-breaker, the labor agitator, the school teacher, the reporter, the stockbroker, the pawnbroker; all of these are characteristic products of the conditions of city life; each, with its special experience, insight, and point of view, determines for each vocational group and for the city as a whole its individuality.
To what extent is the grade of intelligence represented in the different trades and professions dependent upon natural ability?
To what extent is intelligence determined by the character of the occupation and the conditions under which it is practiced?
