The positive school of criminology

One-Page Summary

Enrico Ferri’s The Positive School of Criminology presents the ideas of the nineteenth-century Italian positivist movement that tried to explain crime through empirical study rather than treating criminals simply as morally wicked individuals making isolated choices. Ferri argues that criminal behavior is influenced by a combination of biological, psychological, social, and environmental factors. The lectures therefore shift the question from ‘What punishment does a criminal deserve?’ toward a broader question: what conditions produce crime, and what methods might reduce it?

The book belongs to a historically important period in criminology, but many aspects of positivist criminology—especially older claims about biological criminal types—have been rejected or heavily revised by later research. That makes the work valuable partly as intellectual history. It shows how strongly scientists and social theorists at the time believed human behavior could be studied through the same empirical spirit applied to the natural world. Ferri also treats society itself as an active variable, emphasizing poverty, environment, institutions, and social organization.

Read today, the book is most interesting when the reader sees both its ambition and its limitations. It helped move criminology toward systematic social explanation, while some of its assumptions illustrate why scientific claims about human behavior have to be tested carefully rather than accepted simply because they sound scientific.
