"As a vessel is known by the sound, whether it be cracked or not; so men are proved, by their speeches, whether they be wise or foolish"
About this Quote
The intent is diagnostic, almost prosecutorial. Demosthenes isn’t praising eloquence as art; he’s using speech as a stress test. A cracked vessel can still look intact until it’s struck. Likewise, a citizen (or rival) can posture as prudent until pressured into argument, forced to choose words, sequence reasons, and face contradiction. Speech reveals not only what someone thinks, but how they think: whether their mind holds pressure without splintering into cliché, evasion, or impulsive heat.
The subtext is a warning to a democratic culture that confuses volume with value. Athens rewarded performance, and Demosthenes knew how easily crowds can be seduced by a pleasing tone. His line tries to flip that temptation into vigilance: listen for fissures - inconsistencies, emotional manipulation, convenient vagueness. Wisdom has a timbre: measured claims, earned confidence, a logic that rings clear. Foolishness clangs, even when it’s decorated.
Context matters: Demosthenes spent his career arguing that the city’s real cracks were civic complacency and rhetorical self-deception, especially as Macedon rose. The quote is less etiquette than survival advice: in a crisis, the wrong voices don’t just embarrass a polity; they break it.
