Friendship is the only thing in the world concerning the usefulness of which all mankind are agreed.
Marcus Tullius CiceroRead
Since an intelligence common to us all makes things known to us and formulates them in our minds, honorable actions are ascribed by us to virtue, and dishonorable actions to vice; and only a madman would conclude that these judgments are matters of opinion, and not fixed by nature.
Interpretation
Cicero argues that our moral judgments are not subjective opinions but are rooted in nature's laws.
In this quote, Cicero emphasizes that our understanding of right and wrong is shaped by a common intelligence shared among humanity. He asserts that moral distinctions—who we deem virtuous or vicious—are not mere subjective opinions but are grounded in the inherent nature of reality, suggesting that rejecting these shared moral truths is a sign of madness.
