A Forgotten Classic of Criminological Thought—Reintroduced for the Twenty-First Century

Originally published in 1918 and now carefully edited and introduced by Graeme R. Newman, The Criminology of Crime and Criminals: Medical, Biological and Psychological restores Charles Mercier’s groundbreaking exploration of crime, punishment, criminal behavior, and social order.

Long before modern criminology embraced concepts such as situational crime prevention, environmental opportunity, offender decision-making, and restorative justice, Mercier argued that crime cannot be explained by biology, psychology, or environment alone. Instead, criminal behavior emerges from the interaction between human nature and circumstance, between personal disposition and criminal opportunity.

Rejecting the popular theories of his day, Mercier challenges the notion of the “born criminal” and dismisses simplistic environmental explanations of lawbreaking. His provocative and highly original analysis examines:

• The psychological foundations of criminal conduct

• The roles of instinct, reason, desire, self-control, and will

• How opportunity and temptation shape criminal action

• The classification of crimes and criminals

• The relationship between crime, morality, and society

• The purposes of punishment: deterrence, retaliation, reform, and reparation

• The prevention, detection, and punishment of crime

Mercier’s central insight—that criminals are not a separate species but ordinary human beings responding differently to circumstances—remains strikingly relevant more than a century later.

Graeme R. Newman’s contemporary introduction places Mercier within the broader history of criminological thought and connects his ideas to modern developments in crime prevention and criminal justice. Together, Mercier and Newman illuminate enduring questions that continue to shape public policy and scholarly debate:

Why do people commit crimes? How should society respond? Is prevention more effective than punishment?

Part intellectual history, part criminological theory, and part social philosophy, this edition offers a fascinating window into the origins of modern criminology and the continuing struggle to understand crime and criminals.

Essential reading for students and scholars of criminology, criminal justice, sociology, psychology, legal history, and anyone interested in the causes of crime and the future of punishment.

Why do people commit crime? When does mental illness diminish responsibility? Should punishment always follow wrongdoing?

More than a century before modern debates about criminal responsibility, forensic psychiatry, and the treatment of mentally ill offenders, the distinguished British physician Charles Mercier confronted these enduring questions with remarkable clarity and originality.

In Crime, Insanity and Affliction, Mercier explores the complex relationship between criminal behaviour, mental disorder, and human suffering. Rejecting simplistic explanations, he argues that crime cannot be understood apart from the biological, psychological, and social forces that shape human conduct. His examination ranges from drunkenness, epilepsy, intellectual disability, and mental illness to questions of moral responsibility, punishment, and the proper role of the criminal law.

Although written in the early twentieth century, many of Mercier's observations anticipate debates that continue today. His discussion of diminished responsibility, the treatment of mentally ill offenders, addiction, and the limits of punishment remains surprisingly relevant in an era still struggling to balance justice, compassion, and public safety.

This new Read-Me edition presents Mercier's influential work with a new editorial introduction that places his ideas within the development of modern criminology, forensic psychiatry, and criminal justice. It also examines where Mercier's conclusions have been confirmed, where later research has challenged them, and why his work continues to deserve the attention of students, scholars, and general readers alike.

More than a historical curiosity, Crime, Insanity and Affliction is a thoughtful exploration of one of society's oldest and most difficult questions: how should we judge those whose minds, circumstances, or afflictions place them beyond the ordinary boundaries of responsibility?

The book that criminology forgot — and urgently needs to remember.
Arthur M<ercier (Author). Graeme Newman (Editor and Introduction).

First published in 1918 by the University of London Press, Charles Arthur Mercier's Conduct and Its Disorders, Biologically Considered, published by Macmillan in 1911 is one of the most rigorous, most readable, and most unjustly neglected works in the history of criminological thought. Now reissued as The Biology of Conduct Disorders, with a major critical introduction by Graeme R. Newman, it arrives at a moment when the questions it raises — about criminal intent, biological disposition, the limits of punishment, and the poverty of criminological theory — are more pressing than ever.
Mercier was no armchair theorist. As medical officer of lunatic asylums, consulting physician at criminal trials, and the only systematic student of conduct as a science, he brought to the study of crime a combination of clinical experience and biological rigour that the field had not seen before and has rarely matched since. His target was the prevailing chaos of criminological thought — above all the Continental school of Lombroso, which he dismantled with surgical precision — and his method was the application of praxiology, his own science of conduct, to the specific problem of criminal action.

What Mercier argued — and why it still matters:

• Every criminal act is the product of two factors: an internal factor (the biological constitution of the offender) and an external factor (circumstance and opportunity). Ignoring either produces not criminology but ideology.

• The turpitude of the criminal and the gravity of the crime are entirely separate questions — and confusing them has produced centuries of unjust punishment.

• Punishment should be calibrated to intention, not outcome: the man who intends murder and fails is more culpable than the man who kills by accident, whatever the body count.

• Statistical criminology — mass data gathered from convicted prisoners — cannot produce a science of crime. Only the study of individual criminal action, grounded in biology, psychology, and jurisprudence together, can do that.

• Certain acts currently outside the law (stealing the use of a thing; deliberate breach of contract) deserve criminal status; certain acts currently criminalised do not.

This new edition includes a critical introduction by Graeme R. Newman, Distinguished Professor Emeritus at the School of Criminal Justice, University at Albany, and one of the most provocative and original voices in the study of crime, deviance, and punishment. Author of Comparative Deviance: Perception and Law in Six Cultures, The Punishment Response, Just and Painful: A Case for the Corporal Punishment of Criminals, and Civilization and Barbarism: Punishing Criminals in the Twenty-First Century — and, as Colin Heston, of darkly satirical fiction including The Tommie Felon Show, Miscarriages, and Holy Water — Newman brings a unique authority to this text. Writing with the unflinching directness that earned him national television appearances and a reputation as the most uncomfortable conscience in American criminology, he traces the connections between Mercier's 1918 arguments and the debates that have defined — and divided — the field ever since.
"With the exception of logic, there is no subject on which so much nonsense has been written as this of criminality and the criminal." — Charles Arthur Mercier, 1918
Essential reading for students and scholars of criminology, criminal justice, the history of psychiatry, legal theory, and the philosophy of punishment — and for anyone who has ever wondered why, after two centuries of criminal science, we understand so little about why people commit crimes and what we should do about it.

What’s new? Venezuelan government forces have raided numerous illegal gold mines in the country’s south in recent years, ostensibly to protect the environment. But the truth is that they are exploiting the mines for their own enrichment or allowing armed groups to do so in exchange for a cut of the profits.

Why does it matter? Rising gold prices have fuelled unchecked illegal mining, strengthening Venezuelan criminal enterprises, Colombian guerrilla groups and corrupt elites. The racket destroys fragile ecosystems while also triggering violence against local people and migrant workers, who have been subject to sexual abuse, child labour recruitment and even summary executions.

What should be done? Hard as it is to sway President Nicolás Maduro, foreign governments should use his proclaimed environmental concern and hunger for international legitimacy after the disputed 2024 election to press for curbs on illegal mining and the attendant violence. Buyers, particularly in the Middle East and Asia, should demand conflict-free gold.

Violence in post-conflict settings is often attributed to a post-war boom in organized crime, facilitated by the demobilization of armed groups and the persisting weakness of the state. The article argues that this is only one pathway of post-conflict violence. A second causal pathway emerges from the challenges that peace processes can constitute for entrenched local political orders. By fostering political inclusion, the implementation of peace agreements may threaten subnational political elites that have used the context of armed conflict to ally with armed non-state actors. Violence is then used as a means to preserve such de facto authoritarian local orders. We start from the assumption that these two explanations are not exclusive or competing, but grasp different causal processes that may well both be at work behind the assassination of social leaders (líderes sociales) in Colombia since the 2016 peace agreement with the FARC guerrilla. We argue that this specific type of targeted violence can, in fact, be attributed to different, locally specific configurations that resemble the two pathways. The article combines fuzzy-set Qualitative Comparative Analysis with the case studies of the municipalities

 In January 2024, gunmen invaded a TV studio in Ecuador, seized journalists and staff as hostages, and interrupted the regular programs. That episode highlighted the rise of violence in Ecuador, a country that was until very recently calm and peaceful. In this paper, I place the rise of violence in Ecuador within the context of what some refer to as the endemic violence in Latin America. I explore its risks, consequences, and the ways it could be tackled. I also emphasize some of the dramatic aspects of this endemic violence, such as the fact that in Brazil, 76.5% of homicide victims in 2022 were either black or brown, and every day, 62 individuals aged between 15 and 29 are murdered. I also underline one of the main consequences of this violence: according to the UNHCR, because of criminal violence in Latin America and the Caribbean, 42% of the world’s new asylum seekers are from that region.

Introduction: Community violence intervention street outreach (CVI-SO) strategies are growing in popularity as non-punitive approaches to solving the public health problem of community gun violence. Evidence on the effectiveness of CVI-SO on rates of violence is mixed and faces challenges due to concerns with documentation and data privacy, intentional selection bias in program design, and variation in participant risk and needs. Effective evaluation requires methods that accurately capture the scope and delivery of services, starting with a greater understanding of the services CVI participants receive and how they vary based on individual characteristics.

Methods: This study explores the services that participants received from a coalition of Chicago CVI organizations from 2017–2023. Considering administrative and programmatic data from over 4,000 participants’ nearly 200,000 interactions with providers, the researchers examine patterns in demographics, network-based risk factors, and service provision and dosage. They then use descriptive and latent profile analyses to characterize the “typical” participant in Chicago.

Results: Results show that CVI work relies heavily on long-term mentoring relationships. Service patterns show that latent groups exist with varying dosage: higher dosage participants with higher risk for gun violence receive more frequent contacts over longer periods, demonstrating how organizations adjust their approach based on participant needs. Profiles that primarily receive behavioral or social supports-related services also emerge.

Conclusions: Findings underscore the need for evaluation frameworks that capture both the strategic variation in service delivery and the multiple pathways through which CVI programs influence participant outcomes.

  Colombia is among the countries with the highest levels of violence and crime in the world, despite the peace agreements between the State and different armed groups, including the FARC. This is partly due to the fact that the Colombian case is complex and multifaceted because of the variety of participants in the armed conflict context and due to the mutation of new actors, under the modality of organized crime. Based on the above, the objective is to study the Colombian reality, contextually and diachronically, from theoretical and epistemological elements to demonstrate how violence and criminality factors intersect in the context of the armed conflict. The study concludes, among other findings, that in Colombia the ambiguity and the multiplicity of terms used to name the emerging criminal groups presents a legal problem because of their hybrid composition and regarding their treatment within or outside of the armed conflict

Assessing violence and suicide risk at the population level is essential to inform public health policies and guide prevention efforts for mental health. In Senegal, as in much of sub-Saharan Africa, such data remain scarce. This study aims to fill that gap by estimating the prevalence of violence and suicide risk, and identifying associated factors in the Senegalese population. This nationwide, observational, cross-sectional, population-based analytical survey received ethical approval from Senegal’s National Ethics Committee for Health Research. Conducted between July and August 2023, it covered 496 randomly selected households proportionally distributed by demographic zone. Participants were surveyed on their exposure to different forms of violence, help-seeking behaviours, suicidal ideation and behaviours, and psychiatric history. Data were collected via ODK and analysed in R. Out of 2174 respondents (33.58% youth, 49.95% adults, 16.47% elderly), 52.76% reported exposure to violence, predominantly psychological (47.38%), verbal (43.47%), and physical (32.84%). Co-occurrence was frequent: 37.14% reported combined psychological and physical violence. Age and marital status were strongly linked to violence exposure, with women being more exposed to sexual violence (OR = 1.75 [1.12–2.80]). Dakar was identified as the main violence hotspot. The overall suicide risk was 8.40%, with 1.66% at high risk. Exposure to any form of violence significantly increased suicide risk. Individuals diagnosed with a mental illness were at higher risk (OR = 4.76 [3.13–7.14]). Despite high violence prevalence, support remains rare: only 6.2% received psychological help, 10.4% police assistance. Findings reveal that violence and suicide risk are widespread but insufficiently addressed. The results call for urgent development of a national mental health policy centred on prevention and support for vulnerable groups, especially in the current socio-economic and environmental crisis context.
