"The dictum that truth always triumphs over persecution is one of the pleasant falsehoods which men repeat after one another till they pass into commonplaces, but which all experience refutes"
About this Quote
The line works because it weaponizes deflation. "Dictum" and "commonplaces" reduce a moral anthem to a social tic, something recited for comfort and conformity. Mill's jab is aimed less at persecutors than at the self-satisfied spectators who treat progress as automatic. The real scandal in the sentence is "all experience refutes": a blunt empirical veto against metaphysical optimism. He's insisting that truth has no supernatural momentum; it needs institutions, protections, and stubborn people willing to pay costs.
Context matters. Mill is writing in a 19th-century Britain that congratulated itself on being enlightened while still policing blasphemy, enforcing moral orthodoxies, and marginalizing dissent. In On Liberty, his larger argument is that silencing even "wrong" opinions impoverishes a society's grip on what is right, because truth becomes dead dogma without contest. Here, he sharpens that case by refusing the comforting idea that persecution is self-defeating.
Subtext: if you care about truth, stop treating it like destiny. Treat it like a fragile public good. The triumph, when it happens, is political and cultural work, not cosmic justice.
