Montesquieu put forward unique insights in the field of crime and crime governance.He believed that the determination regarding whether a behavior constitutes a crime should be stipulated based on specific circumstances and emphasized that crime governance should revolve around the principle of restraining power and safeguarding the inviolability of the rights of the individual.At the same time,he strongly opposed the excessive use of heavy penalties and strongly advocated the principle of the legality of crimes and punishments.These views constitute the core idea of Montesquieu's crime governance,and he further proposed a set of constraints on the power of governance and a comprehensive system of"criminal law,civil law and administrative law"governance.The positive role of good customs and practices in preventing crime and reducing the incidence of crime is recognized alongside the rule of law,thus achieving the dual goals of effective crime prevention and significant reduction of crime.These views of Montesquieu not only have a far-reaching influence on later generations,but also provide a reference for contemporary China in the field of crime governance.
