Why do people commit crimes? How do we control crime? The theories that
criminologists use to answer these questions are built on a number of
underlying assumptions, including those about the nature of crime, free
will, human nature, and society. These assumptions have a fundamental
impact on criminology: they largely determine what criminologists study,
the causes they examine, the control strategies they recommend, and how
they test their theories and evaluate crime-control strategies.
In Toward a Unified Criminology, noted criminologist Robert Agnew
provides a critical examination of these assumptions, drawing on a range
of research and perspectives to argue that these assumptions are too
restrictive, unduly limiting the types of crime that are explored, the
causes that are considered, and the methods of data collection and
analysis that are employed. As such, they undermine our ability to
explain and control crime. Agnew then proposes an alternative set of
assumptions, drawing heavily on both mainstream and critical theories of
criminology, with the goal of laying the foundation for a unified
criminology that is better able to explain a broader range of crimes.
