"Any man can make mistakes, but only an idiot persists in his error"
About this Quote
The intent isn’t self-help; it’s social control. In the Roman Republic, a statesman’s legitimacy depended on appearing rational, adaptable, guided by mos maiorum (custom) and prudence. To persist in an error wasn’t just inefficient; it signaled that you were unfit for governance, captive to ego, faction, or passion. Cicero is drawing a bright line between corrigible misjudgment and culpable obstinacy - a line that lets an audience forgive yesterday’s blunder while demanding today’s correction.
The subtext is strategic: change your mind and you can still be honorable. Refuse, and you become “an idiot,” a category that removes you from serious debate. That’s classic Ciceronian rhetoric: make the virtuous choice (revision) the only choice available to a person who wants to be seen as intelligent.
Read in context of Rome’s late-republic crisis - conspiracies, civil war jitters, demagogues, collapsing norms - the quote doubles as an anti-populist warning. It’s not attacking error; it’s attacking the pride that turns error into policy.

Evidence:
Any man is liable to a mistake; but no one but a downright fool will persist in error. (Book XII, section II, §5 (often cited as 12.5)). The popular modern wording (“Any man can make mistakes, but only an idiot persists in his error”) appears to be a loose paraphrase. Cicero’s primary-source text is in the *Philippicae* (a series of speeches delivered/published in 44–43 BCE). In *Philippics* 12.5 Cicero says (Latin): “Cuiusvis hominis est errare, nullius nisi insipientis in errore perseverare; posteriores enim cogitationes, ut aiunt, sapientiores solent esse.” A public-domain English translation by C. D. Yonge renders the key sentence as quoted above. A second primary-text witness for the Latin is also available online via Wikiversity’s excerpt with section labeling (XII.II §5.2).
