Carl Ritter is not such a geographer as usually explained a man of lilrauy but an unique morphologist who tried to begin with the observation of the familiar natures and make the diversity of them systematic according to their forms.
The tradition of “Naturgeus” originated from Renaissance and the current of thoughts towards German classic were so developed that it is not enough for the geographers to regard the world as a organic body.
In the days of Ritter the thought of “life” which was beld by Herder and others was necessarily embodied in the though of the earth. This is the reason why he made much of form in his Geography.
