Criminology is the study of ideas and theory’s in the criminal justice system and the actions and processes which are initiated, in correlation with crimes, and the criminals who commit them. The key to understanding the criminal justice system is to have a concise understanding of the theories on how, and why crimes are committed. Once there is an understanding of these factors, there then is ability to pass an educated judgement, on the reasoning behind the factors of crime, and criminality in general. The two main theories, which have been crucial to the thinking, and understanding of criminology, are the Positive School, and Classical School. Both of these schools were developed between the 14th and 17th century and have been instrumental in the construction of our criminal justice system throughout history, and into the present.

        The Classical School is based on two main theorists, Jeremy Bentham and Cesare Beccaria, who developed their ideas from the late 1700’s, to the early 1800’s.   Some of the key points, which are addressed, are deterrence, hedonism, and social contract.

(Sacco, Kennedy, 2002) Other thoerists in the Positive School movement were Raffaele Garofalo, and Enrico Ferri who also had major contributions. The key points behind the Positive School are determinism, treatment, and atavism. The Positive School considered the cause and effects of crime, rather then crime being a product of free will.
