Final answer:
Athenians believed public discussion was essential for rational debate and the exercise of judgment concerning the common good, in line with Aristotle's and Plato's philosophies.
Step-by-step explanation:
The Athenians viewed public discussion as useful before taking action because it allowed them to exercise their capacity for rational debate, discussion, and judgment regarding the common good. This idea was rooted in the philosophy of Aristotle who emphasized that taking part in political power through debate was essential for reaching one's full potential as a human.
Likewise, Socratic questioning in Plato's dialogues served as a tool for revealing truth through reasoned discourse, allowing individuals to discover truths for themselves. The practice of public debate was further entrenched in Athenian democracy through the public assembly, where citizens utilized their rhetorical skill to influence decisions, reaffirming the belief that the practice of persuasion and reasoned argument was vital for the functioning of their society.
