Final answer:
Cicero's concept of justice is based on harmony and specialization in society, where each individual fulfills their duties without interfering with others. His ideas on justice influenced legal systems by emphasizing fairness, the presumption of innocence, and the consideration of the spirit of the law.
Step-by-step explanation:
Cicero's concept of justice is consistent with the idea of harmony and specialization in society. He believed that justice is achieved when every individual fulfills their duties in their appointed place without interfering with the duties of others. This principle of non-interference leads to a society that is internally harmonious and good.
Cicero's ideas on justice may have influenced legal systems by emphasizing the importance of fairness and the presumption of innocence. His concept that someone accused of a crime is innocent until proven guilty was a radical idea at the time, but it laid the foundation for the modern legal principle of due process. Cicero's belief in the harmony of relationship and the fulfillment of appropriate functions in society may have also influenced the development of legal systems based on precedents and the consideration of the spirit of the law.
