Doc's CJ Glossary by Adam J. McKee

Cicero, a Roman philosopher and statesman, contributed to criminology through his ideas on law, justice, and moral responsibility, influencing modern legal thought.

Introduction to Cicero

Marcus Tullius Cicero (106–43 BCE) was a Roman philosopher, lawyer, and politician whose writings on law, justice, and governance have influenced Western legal systems. While not a criminologist in the modern sense, his ideas on natural law, punishment, and civic responsibility have shaped criminal justice theories. His belief that laws should be based on reason and morality continues to impact legal philosophy, ethics, and criminological thought today.

Cicero’s work provides foundational principles for modern discussions on justice, fairness, and the role of the state in crime control. His writings emphasize the importance of laws in maintaining order and protecting individual rights while also warning against tyranny and corruption.

Cicero’s Philosophy of Law and Justice

Cicero believed in the concept of natural law, arguing that justice is universal and not merely a construct of human governments. He asserted that laws should be based on reason and morality rather than arbitrary power. His ideas are foundational to modern legal and criminological theories, particularly in discussions about the fairness and legitimacy of laws.

1. Natural Law and Justice

Cicero argued that:

  • Laws should reflect natural law—a higher moral order that applies to all people, regardless of government or culture.
  • Justice is not determined by power but by rational principles that apply equally to everyone.
  • Governments must create laws that align with reason and fairness, as unjust laws lead to social instability and crime.

His view on natural law influenced later thinkers such as John Locke and Thomas Jefferson, shaping modern constitutional democracies and criminal justice systems that emphasize human rights.

2. The Purpose of Punishment

Cicero discussed punishment in the context of maintaining social order and deterring crime. His ideas align with later criminological theories on the purposes of punishment, including:

  • Retribution – Criminals should face consequences for their actions as a matter of justice.
  • Deterrence – Punishment should prevent others from committing crimes.
  • Rehabilitation – While less emphasized in his time, Cicero suggested that laws should encourage good behavior.

His emphasis on rational laws influenced later legal theorists who shaped modern correctional philosophies.

3. The Role of the State in Crime and Justice

Cicero believed that the state exists to serve the people, not to oppress them. He argued that:

  • The government must protect citizens from crime while ensuring fair treatment for all.
  • Corruption in law enforcement and the courts leads to crime and disorder.
  • A just government is one that enforces laws fairly, without bias or favoritism.

These ideas remain relevant in discussions about police reform, legal ethics, and judicial fairness.

Cicero’s Influence on Criminology and Legal Theory

Cicero’s work has had a lasting impact on legal philosophy, influencing many criminological theories and modern justice systems.

1. Influence on Classical Criminology

Classical criminology, developed in the 18th century by thinkers like Cesare Beccaria and Jeremy Bentham, is rooted in many of Cicero’s principles, including:

  • The idea that laws should be rational and just
  • The belief that punishment should be proportionate to the crime
  • The emphasis on individual responsibility and free will

Beccaria’s famous work On Crimes and Punishments (1764) echoes Cicero’s call for laws based on reason rather than arbitrary power.

2. Influence on Legal and Political Thought

Cicero’s ideas influenced the development of constitutional law and human rights, which are essential to modern criminal justice systems. His belief in natural law shaped the legal philosophies of:

  • John Locke – Who argued that governments must protect life, liberty, and property.
  • The Founding Fathers of the United States – Who incorporated principles of fairness, due process, and justice into the U.S. Constitution.
  • Modern international law – Which emphasizes human rights and legal fairness in global justice systems.

3. The Connection to Social Contract Theory

Cicero’s views on the role of government in maintaining order influenced later social contract theorists, such as:

  • Thomas Hobbes – Who argued that strong governments are necessary to prevent chaos.
  • John Locke – Who believed governments must be accountable to the people.
  • Jean-Jacques Rousseau – Who emphasized individual rights and justice.

Social contract theory remains central to criminology, as it explains why laws exist and how governments should enforce them fairly.

Cicero’s Relevance to Modern Criminology

Although Cicero lived over 2,000 years ago, his ideas remain highly relevant to modern criminal justice debates. Some key areas where his philosophy applies include:

1. Criminal Law and Fair Punishment

Cicero’s insistence that laws be based on justice and reason aligns with modern principles of due process and fair sentencing. His warnings against excessive punishment are echoed in:

  • Opposition to the death penalty in many legal systems today.
  • Efforts to reform harsh sentencing laws for nonviolent offenses.
  • Debates about mass incarceration and its fairness.

2. Corruption and the Abuse of Power

Cicero condemned corruption in government and the courts, a concern that continues today. His warnings apply to:

  • Police misconduct and excessive force
  • Judicial corruption and unfair trials
  • Political influence on criminal justice policies

Modern movements for legal transparency and police accountability reflect Cicero’s concerns about justice and fairness.

3. Human Rights and the Rule of Law

Cicero’s belief in universal justice and natural rights laid the groundwork for modern human rights laws. Today, these ideas support:

  • International laws against torture and wrongful imprisonment
  • Legal protections for marginalized groups
  • The fight against authoritarianism and unjust laws

Conclusion

Cicero’s contributions to law and justice remain deeply relevant in criminology. His ideas on natural law, fair punishment, and the role of the state have influenced classical criminology, legal philosophy, and modern human rights. As criminal justice systems evolve, his emphasis on reason, morality, and justice continues to shape discussions on crime and punishment
