For centuries scholars have studied the possible causes of criminal behavior in the hopes of shedding light on one of society's most persistent problems. This volume examines criminology from the perspective of those centuries of study. Written by a psychologist who has worked extensively with the criminal population, it focuses on the diverse theories that have been offered and the ways in which they contribute to the modern view of the criminal. The correlates of crime such as age, gender, race and IQ are discussed along with more random factors such as choice and chance. Theories of biology, psychology and sociology are all discussed. Criminological sources from the 18th century through the end of the 20th are cited and major developments noted. Finally, a brief preview of 21st century criminology considers how the lessons of the past might be adapted and drawn upon for future discoveries.
