HUMAN NATURE AND CITY LIFE The city is remaking human nature and each city is producing its own type of personality. These influences of city life are of prime interest to the sociologist. The materials bearing on this question are not primarily those collected by the scientist, but by the artist. It requires insight and imagination to perceive and to describe these deep-seated changes which are being wrought in the nature of man himself. 1. The division of labor and the fine specialization of occupations and professions that is so distinctly characteristic of city life has brought into existence a new mode of thought and new habits and attitudes which have transformed man in a few generations. The city man tends to think less in terms of locality than he does in terms of occupation. In a sense he has become an adjunct of the machine which he operates and the tools he uses. His interests are organized around his occupation, and his status and mode of life is determined by it. Bahre, Walter. _Meine Klienten._ Vol. XLII in “Grossstadt Dokumente” (Berlin, 1905).
