Abstract
The article considers historical and actual aspects of social biologism. The historical aspects of biologism should help to describe the social content and quasi-scientific basis of socio-biologistic ideas in the contemporary world. The author shows the connections between many forms of socio-biologistic discourses and the structure of social relations. He proves that ideas of social biologism function as an ideological justification for different phenomena of social inequality, but at the same time they formulate a condition for its material reproduction. The connection between sociobiologistic ideology and practice is shown by the examples of the main historical forms which social biologism took in the 19th century. These examples include colonial racism, class-racism, anti-Semitism, and psychiatric biologism.
