Sociology of biological inspiration in the XIXth century:: a science of social "organization"

Sociology of biological inspiration from the XIXth century - at least the important names such as Saint-Simon, Comte, Spencer and Durkheim - is not understandable if one refers to the opposition between " mechanical models " and " organic models ". This sociology is not based on the romantic figure of the organism as a counter enhancement of the machine: it turns around the notion of organization as developed in the first half of the XIXth century in natural history. In this sociology the logical theme for the classification of organized forms also plays a crucial role.
