The classical school of criminology is a group of thinkers of crime and punishment in the 18th century. Probably the most prominent members, such as Cesare Beccaria, shared the theory that criminal behavior could be understood and controlled. The classical theory insisted that folks are rational beings who pursue their own interests, trying to increase their pleasure and minimize their pain. The following manuscript will cover three key concepts the origins of classical thought, popular forerunner of classical thought, Cesare Beccaria, and how the classical theory pertains to crime prevention. Lastly, the educational material will show that crime is caused by natural forces and the lack of effective punishment allows it to continue. With evidently defined laws, public punishment, and the elimination of judicial discretion crime can be avoided by deterrence.
