Enrico Ferri 
Positive School of Criminology [PDF ebook] 
Three Lectures Given at the University of Naples, Italy on April 22, 23 and 24, 1901

Enrico Ferri was a prominent figure in the early development of the field of criminology. The school of thought that he developed, which came to be known as positivism, sought to identify and address the social, economic and environmental factors that contributed to the emergence of criminal and antisocial behavior in some people. The three lectures in this volume bring together many of Ferri’s most influential ideas and theories.
