Summary up to 500 words

In *Criminal Psychology*, Hans Gross presents a revolutionary framework for the judicial system, arguing that modern criminal science must abandon the archaic notion of inscrutable free will. Drawing a direct parallel between the evolution of medicine and the understanding of crime, Gross asserts that just as disease has natural causes requiring specific treatments rather than indiscriminate remedies like calomel or bloodletting, crime is also caused by identifiable circumstances. He advocates for the 'individualization of penal treatment,' where justice is adapted to the unique causes and circumstances of each offender. Gross systematically investigates the fallibility of human perception, particularly regarding witness testimony. He demonstrates that human conceptions of time are highly unreliable; witnesses often drastically misestimate short durations and rely on distinct events to anchor longer periods. Furthermore, he explores the profound impact of 'nurture'—environment, education, and upbringing—on moral development. He challenges the assumption that literacy prevents crime, noting that increased education often instills unattainable desires that can lead to new forms of criminality, such as swindling, rather than eliminating it. Conversely, he highlights that individuals with limited education may possess integrity but suffer from psychological limitations in perceiving reality accurately. The text delves into the subconscious, the nature of illusions, and the influence of suggestion on memory, warning against the tendency of uneducated individuals to define abstract concepts rather than observing immediate perception. By integrating insights from anthropology, medicine, and sociology, Gross provides a comprehensive framework for understanding the interplay of heredity and environment. He urges legal professionals to adopt a scientific, empathetic, and precise approach, recognizing that the law must evolve to reflect the complex natural causes of criminal behavior rather than relying on traditional, machine-like measures of punishment.
