In Cicero's rhetoric, what does "ratio" signify?

In Cicero's rhetoric, "ratio" signifies reason. This term is fundamental to Cicero's ideas on persuasive discourse, where he emphasizes the importance of logical argumentation and rational appeal in convincing an audience. "Ratio" reflects the ability to analyze, deduce, and construct arguments based on logic and evidence rather than emotional appeal or anecdotal experiences. Cicero often distinguished rational discourse from emotional strategies, advocating for a balance between the two but grounding the essence of persuasion in the clarity and strength of reasoned argumentation. This understanding of "ratio" underlines its pivotal role in effective oratory and philosophical thought during Cicero's time, where the ideal orator was one who could engage the intellect of listeners.
