A Summary of Ferri's Social Defense Theory from the Perspective of Positivism Philosophy

摘要

With the further deepening of natural science research, human genetics and biology have developed rapidly. The Italian school of criminals, represented by C. Lombroso, developed rapidly in the 1970s. It believed that crime is an inevitable phenomenon of nature. It put forward the theory of "born criminals" and opened up a precedent for positivism. His disciple, Enrico Ferri, developed the theory of C. Lombroso and belonged to the criminal sociology school. He believed that the reason of crime is not completely determined by the individual's biological genes, but the result of the combination of physiological genes, natural conditions and social environment. From the perspective of positivism philosophy, this paper studies the social defense theory of Ferri, a representative of the criminal society school, in order to better serve the development of punishment and promote the further deepening of the study of penalty theory.
