The work explores the nature of the born criminal, distinguishing between classical and modern schools of penal jurisprudence. The authors argue that anti-social tendencies are the result of a physical and psychological organization that differs fundamentally from normal individuals. Through extensive anthropological examinations, Lombroso identifies numerous physical anomalies in criminals, such as cranial asymmetries, unusual jaw formations, facial irregularities, and prehensile feet, which correlate with the traits of primitive ancestors and lower animals.
Building upon the atavistic theory, the text connects congenital criminality to moral insanity and epilepsy. The author demonstrates that born criminals, epileptics, and morally insane individuals share identical traits, including a lack of moral sense, extreme impulsiveness, vanity, idleness, and an absence of remorse. These psychological and physical markers indicate that crime is a pathological condition rather than merely a conscious choice.
Beyond the born criminal, the authors classify other offenders, such as insane criminals, alcoholics, and hysterical subjects, whose anti-social acts stem from specific mental alterations or nervous diseases. Alcoholism, in particular, acts as a powerful catalyst, producing hallucinations, apathy, and violent impulses that drive individuals to commit serious crimes without genuine premeditation.
The text also examines criminaloids, habitual criminals, and criminals of passion. Unlike the born criminal, criminaloids possess no major physical anomalies and commit crimes later in life due to external factors, environment, or temptation. Criminals of passion, representing the opposite extreme, are driven by altruism, honor, or intense emotion, and their actions are typically unpremeditated and accompanied by deep remorse.
The origin and causes of crime are traced through historical, social, and hereditary factors. While heredity and atavism form the primary organic base, external influences such as education, density of population, meteoric conditions, and economic status play significant roles in the manifestation of criminal behavior. The authors demonstrate that crime is deeply rooted in human evolution and social structures.
Finally, the text outlines modern methods for the prevention, cure, and repression of crime. Moving away from traditional punitive imprisonment, which often fosters further criminality, the authors advocate for preventive institutions for destitute children, the probation system, juvenile courts, and specialized reformatories. For incurable offenders, the solution lies in humane segregation through penal colonies and specialized asylums, balancing social safety with rehabilitation.
