This paper reviews Cesare Beccaria's landmark 1764 work, An Essay on Crimes and Punishments, widely credited with revolutionizing modern penology. Drawing on peer-reviewed scholarship, the review examines Beccaria's core arguments: his condemnation of torture and capital punishment, his call for proportionate sentencing, and his emphasis on deterrence over retribution. The paper also considers his views on witness credibility, the potential for tyranny in unjust legal systems, and the enduring relevance of his ideas to contemporary criminal justice reform in the United States and internationally. Beccaria's influence on Enlightenment-era legal reform and subsequent international agreements, such as the UN Convention Against Torture, is highlighted throughout.
The paper demonstrates effective use of primary source analysis alongside secondary scholarly commentary. By quoting Beccaria directly and then contextualizing those quotes with modern legal and criminological scholarship, the author shows how to build a layered argument that bridges historical texts and present-day policy debates.
The paper opens with a framing introduction that states its purpose and scope. The body proceeds thematically rather than strictly chronologically, moving from Beccaria's general influence to his specific arguments on torture, capital punishment, deterrence, proportionality, and witness credibility. Each theme is tied back to contemporary relevance. The conclusion synthesizes the key findings and affirms Beccaria's enduring significance to modern jurisprudence.
Today, the United States incarcerates more of its citizens than any other industrialized nation, and their confinement is determined by the nature of their respective offenses. Although many may not realize it, these individuals owe a significant debt to Cesare Beccaria's early work in penology, since they are no longer subject to torture and fewer criminals are being executed for capital offenses. The purpose of this paper is to provide a review of Cesare Beccaria's (1764) An Essay on Crimes and Punishments. This essay is credited with revolutionizing modern penology by advocating for rational, humane, and proportionate punishments. His work emphasized deterrence over retribution, condemned the use of torture and the death penalty, and laid the foundation for criminal justice reforms centered on fairness, legality, and the protection of individual rights — influencing legal systems worldwide. Following a review of the relevant peer-reviewed literature and a critical analysis, a summary of the essay's main points and key findings is provided in the conclusion.
Today, many prisons in the United States are struggling to cope with overcrowded facilities, razor-thin budgets, and staffing shortages that preclude most rehabilitative programs in favor of security. Nevertheless, inmates in modern prisons are treated far better than their counterparts in the not-too-distant past, and they can credit Beccaria's 1764 An Essay on Crimes and Punishments for multiple reforms that transformed prisons from the brutal institutions that freely applied torture and the death penalty during the 18th and early 19th centuries (Haney, 2016).
According to Rahe et al. (2024), Beccaria's book was one of the more influential texts on penology of its time, especially with respect to the unacceptability of torture as punishment, with long-lasting implications for modern criminal justice. Rahe and his associates at the U.S. National Constitution Center emphasize that "the impact of his little book on the post-revolutionary revisal of the laws in the various nascent American states was considerable" (para. 3).
It is reasonable to suggest that many people at the time were unaware of, or unconcerned about, the horrific conditions in the nation's prisons unless they or their family members had personal experience with the criminal justice system — until Beccaria's essay became widely known. Much like Upton Sinclair's exposé of the unsanitary practices of the Chicago meatpacking industry in The Jungle, which resulted in the passage of the Pure Food and Drug Act and the Meat Inspection Act in 1906, Beccaria's book was the catalyst that fueled fundamental reforms in the prison system — reforms that endure to the present. In this regard, Panov (2016) cites the book's "significance in reformation, development and improvement of legislation on criminal justice, as well as the formation of science of criminal law, criminal procedure, jurisdiction, criminology and other sciences" (p. 226).
Among other critical reforms, Beccaria's book generated significant attention concerning the appropriateness of the death penalty in the Age of Enlightenment. Prior to that era, execution was generally accepted as a fitting punishment for a wide array of offenses, most of which are not capital crimes today. The publication of Beccaria's influential work in 1764 significantly altered the discourse surrounding capital punishment and the effectiveness of incarceration in both America and internationally (Bessler, 2018).
Two of the most important points made by Beccaria that still influence the criminal justice system today are his calls for the elimination of both torture and the death penalty, which he addresses in separate chapters of An Essay on Crimes and Punishments. As a result of Beccaria's advocacy, American lawmakers took steps to limit the use of torture and capital punishment during the latter half of the 18th century, with mixed success. Since that time, countries worldwide have become signatories to the UN Convention Against Torture, which took effect in 1987 and was ratified by the United States in 1994 (Bessler, 2018).
Consequently, torture — once officially sanctioned under civil law with the primary goal of inflicting physical harm — is now outlawed and recognized by the international community as causing severe mental or physical suffering, including when used for extracting confessions or as a form of punishment in its own right. Beccaria himself emphasized this point directly:
"The torture of a criminal, during the course of his trial, is a cruelty, consecrated by custom in most nations. It is used with an intent either to make him confess his crime, or explain some contradictions, into which he had been led during his examination; or discover his accomplices; or for some kind of metaphysical and incomprehensible purgation of infamy; or, finally, in order to discover other crimes, of which he is not accused, but of which he may be guilty." (1764, chap. XVI)
Numerous international agreements have reinforced this ban, with no exceptions permitted even during emergencies or hostile conflicts (Bessler, 2019). While so-called "waterboarding" has been applied in the interrogation of September 11, 2001 terrorist suspects at Guantanamo Bay, these episodes remain major outliers in an international community that broadly agrees there is no place for torture in the 21st century.
With respect to capital punishment, death sentences and the frequently botched executions that follow also cause extreme trauma and share many characteristics with torture, affecting not only the condemned but also their loved ones, legal representatives, and corrections staff (Bessler, 2019). Critics argue that the practice should be categorized as torture and prohibited under both American and international law. This perspective draws on research in legal, psychological, and psychiatric fields, incorporating insights from mental health professionals, medical experts, and judicial opinions on psychological torture, as well as prior U.S. Supreme Court holdings that reject torture as a profound violation of constitutional and international law (Bessler, 2019).
It is also noteworthy that Beccaria adopted a pragmatic view of the death penalty. Rather than opposing capital punishment solely on the grounds of its finality or unusual cruelty, Beccaria believed the death penalty was not worth its cost given its ineffectiveness in deterring crime. As Sitze (2008) notes, "While traditional anti-death penalty literature has focused on its cruelty and inhumanity as a reason for abolishing the practice, [Beccaria] looks at works that decry it because of its uselessness for the well-being and security of the public" (p. 598).
Beccaria's arguments also extended to calling for a "let the punishment fit the crime" approach that provided proportionate penalties for breaking the law, with particular emphasis on what works best in preventing rather than merely punishing criminal acts. In his chapter "Of Crimes which Disturb the Public Tranquility," Beccaria poses a series of questions that encapsulate his reformist agenda:
"What are, in general, the proper punishments for crimes? Is the punishment of death, really useful, or necessary for the safety or good order of society? Are tortures and torments consistent with justice, or do they answer the end proposed by the laws? Which is the best method of preventing crimes? Are the same punishments equally useful at all times?" (1764, chap. XI)
Because torture and the death penalty were ineffective in diminishing the frequency of capital crimes or as preventive measures, Beccaria maintained that both were counterproductive to the best interests of society. As he wrote, "It is not only the common interest of mankind that crimes should not be committed, but that crimes of every kind should be less frequent" (1764, chap. VI).
Beccaria further argues that humans are essentially hard-wired toward violence, observing that "In vain have the laws endeavoured to abolish the [single combat] custom, by punishing the offenders with death" (1764, chap. X). Many humans in the 18th century — as today — are the descendants of people who used coercion, threats, and violence to survive. This powerful genetic legacy does not disappear overnight, and the death penalty has continued to fail as a deterrent to crimes of passion and premeditated murder alike.
This is not to dismiss the arguments of death penalty advocates, who point out that executed murderers are guaranteed to commit no further crimes, and that some acts are so heinous as to warrant the severest available penalty. It is to say, however, that Beccaria's seminal work has compelled lawmakers and the public to reconsider whether the criminal justice system should prioritize punishing offenders or preventing crimes in the first place — a debate that has continued for more than 260 years.
The issue of the limited utility of punishment in achieving substantive restorative justice was also addressed in Beccaria's chapter "Of the Intent of Punishments," in which he writes:
"[I]t is evident, that the intent of punishments is not to torment a sensible being, nor to undo a crime already committed. Is it possible that torments, and useless cruelty, the instruments of furious fanaticism, or of impotency of tyrants, can be authorized by a political body? which, so far from being influenced by passion, should be the cool moderator of the passions of individuals. Can the groans of a tortured wretch recall the time past, or reverse the crime he has committed?" (1764, chap. XII)
A common refrain among prisoners throughout history is the wish to travel back in time to avoid their crimes, but remorseful hindsight cannot substitute for legal punishment. Moreover, there are circumstances in which treating criminal offenders as a "cool moderator of the passions of individuals" would be entirely inappropriate — particularly when those passions translate into the torture of innocent people or genocidal acts.
The research showed that Beccaria's An Essay on Crimes and Punishments remains an influential work in the field of criminal justice, challenging long-held beliefs about the purpose of punishment and calling for a more humane, rational approach to criminal law. The research also demonstrated that his emphasis on deterrence over retribution, proportionality in sentencing, and the abolition of torture and capital punishment has left a lasting mark on modern legal systems worldwide. In sum, Beccaria's ideas not only influenced the Founding Fathers of the United States but continue to shape debates on criminal justice reform today. While some of his arguments remain controversial — particularly regarding capital punishment — his core principles of fairness, legality, and the protection of individual rights have become fundamental features of modern jurisprudence.
