"No one knows what he can do until he tries"
About this Quote
A line like this survives two millennia because it flatters and dares you at the same time. Publilius Syrus, a Roman writer of punchy moral maxims, isn’t offering inspiration so much as a corrective to the era’s favorite self-deceptions: boasting, fatalism, and the comfortable belief that your limits are prewritten. “No one knows” is a quiet swipe at certainty itself. It punctures the ego of the braggart and the resignation of the coward with the same needle: you don’t actually have evidence until you act.
The sentence is built like a trapdoor. “Can do” sounds like innate capacity, a fixed trait. Then “until he tries” yanks it back into the realm of choice and risk. Ability becomes something revealed by behavior, not declared by identity. The subtext is almost prosecutorial: if you haven’t attempted it, your opinion about your potential is inadmissible. That’s why it reads as timelessly modern; it treats self-knowledge as an experiment, not a confession.
Context matters. Syrus wrote in a culture obsessed with status, performance, and public reputation, where failure could be humiliating and courage was prized as civic theater. The line’s intent isn’t to promise success; it’s to shame passivity. Try, and you may discover talent - or discover limits - but either way you escape the soft tyranny of speculation. In a society that loved maxims, this one works because it replaces moralizing with a simple demand for proof.
