Biography of Cicero

Cicero, better known as Marcus Tullius Cicero, was a great orator, statesman, and Roman philosopher who lived in the first century BC. Born in 106 BC in Arpinum, Italy, Cicero grew up as a brilliant rhetorician and received a solid legal education. His political career took off when he was elected consul in 63 BC. During this time, Cicero fought to defend the Roman Republic from the threat of oligarchy and conspiracy. His most famous works, such as “De Oratore” and “De Re Publica,” reflect his deep thinking about ethics, law, and political systems. Even though he was later involved in dangerous political intrigue, Cicero remained consistent in maintaining the values of republicanism and justice. However, his political career ended tragically when he was executed by Triumvirate troops in 43 BC. Despite this, Cicero’s legacy in the fields of rhetoric and political thought remains undeniable, influencing Western intellectual thought for centuries.

Cicero’ Thoughts

Natural law

Natural law, according to Cicero’s perspective, is a philosophical concept that recognizes the existence of universal legal principles inherent in the universe and human reason. Cicero, a prominent Roman statesman and orator of the first century BC, developed this idea in his famous works, especially “De Legibus” and “De Re Publica.” For him, natural law is not merely a product of human convention but rather a moral norm that is inherent in natural existence and can be accessed through common sense. Cicero viewed natural law as a guide to correct human action, asserting that obedience to natural law leads to justice and social harmony. This principle involves the idea that humans have inherent rights and moral obligations that do not simply derive from social norms or the decisions of authorities. In Cicero’s concept of natural law, there is a belief that moral truth originates from natural law itself, creating a strong foundation for understanding ethics, justice, and the ideal social order. As time goes by, the legacy of Cicero’s thoughts on natural law continues to contribute to the development of legal and ethical theory, forming a deep philosophical foundation in his view of the principles of universal justice.


Republicanism, according to Cicero’s thinking, represents a political system that prioritizes the freedom and participation of citizens in public affairs. Cicero, as one of the leading figures in Rome in the first century BC, formulated this concept through his writings, especially “De Re Publica.” In Cicero’s view, republicanism signifies the primacy of a state run by the active participation of its citizens, where the common good takes precedence over personal interests. Good government, according to him, must be based on moral principles and justice and avoid corruption and tyranny. Cicero advocated a combination of elements of monarchy, aristocracy, and democracy in a constitutional system to achieve an optimal balance of power. Thus, Cicero’s republicanism emphasized not only the political structure but also the morality and responsibility of citizens. This concept remains relevant in contemporary political debates, providing inspiration for the view that societal well-being can be achieved through active participation, justice, and governance based on good policies.

Mixed Constitution

A mixed constitution, according to Cicero’s thinking, is a political concept that embraces the idea of dividing power in a government. In his works, especially “De Re Publica,” Cicero introduced this concept as a way to prevent concentrations of power that could potentially lead to tyranny. For him, a mixed constitution combines elements of monarchy, aristocracy, and democracy in a balanced framework. Monarchy, or one-person leadership, is balanced by aristocracy, which places an elite group in decision-making, while democracy provides a role for broad citizen participation. Thus, the Mixed Constitution offers a solution to avoid potential abuse of power and maintain political stability. This concept creates a system where power is not centralized in one entity but is distributed with the aim of achieving justice and balance. Although, over time, the direct implementation of this concept may be complex, the legacy of Cicero’s Mixed Constitution ideas nevertheless contributes to discussions about optimal forms of government and avoids the risks of authoritarianism or the dominance of small groups.


Rhetoric, in Cicero’s view, is the art and skill of using words effectively to influence the opinions and actions of others. Cicero, a great Roman orator in the first century BC, considered rhetoric to be a primary tool for shaping public opinion and gaining political support. In his famous works, such as “De Oratore,” Cicero developed rhetorical principles involving clarity of expression, power of persuasion, and the use of a dazzling style. For him, rhetoric is not only related to speaking skills but also involves skills in understanding the audience and conveying messages effectively. Cicero emphasized that a skilled orator must have broad knowledge, high ethical standards, and the ability to adapt to different situations. Cicero’s rhetorical legacy not only influenced the art of speaking but also provided the basis for the development of communication skills in a variety of fields, including politics, law, and education. Thus, Cicero’s contributions to rhetoric not only became a cornerstone in the history of Roman literature but also provided inspiration for the development of effective speaking skills in a variety of modern contexts.

Freedom of Thought

Freedom of thought, in Cicero’s view, is a fundamental right inherent in human dignity and is the basis for the intellectual development of society. Cicero, a Roman statesman and philosopher of the first century BC, put forward this idea through his famous works, especially “De Officiis.” For him, freedom of thought includes the right of every individual to voice his opinion, accept or reject ideas, and seek the truth without pressure or unlawful restrictions. In Cicero’s thinking, freedom of thought is not only a right, but also a moral responsibility. He taught that an intellectually developed society requires an environment that supports a diversity of ideas and open discussion. Cicero emphasized that freedom of thought not only creates intellectual well-being, but also promotes moral and ethical development in society. His contribution to the idea of freedom of thought provides a philosophical basis for the protection of human rights that continues to be relevant in the context of modern society. By maintaining freedom of thought, humans can realize their creative potential, advance knowledge, and develop an inclusive and progressive society.

The conclusions in Cicero’s thought reflect a synthesis of his views on ethics, politics, and rhetoric. Through his works, especially “De Officiis,” Cicero emphasized that wise and ethical conclusions must rely on the principles of natural law, moral virtue, and civic responsibility. For him, making the right decision requires deep consideration of justice, wisdom, and the common welfare. Conclusions, in an ethical context, are closely related to judgments about what is right and good and how these actions can create harmony in society. On the political side, Cicero formulated the conclusion that republicanism, with the concept of a mixed constitution, could be the basis for preventing corruption in power and maintaining political stability. In addition, in the rhetorical aspect, the conclusion is not just the end of an argument but also the moment where the orator must influence the audience’s opinion strongly and convincingly. The conclusions in Cicero’s thought reflect his entire legacy, illustrating his holistic view of morality, political order, and the wisdom of effective speech.
