"The only good is knowledge, and the only evil is ignorance"
About this Quote
The line works because it smuggles an ethic into a method. Herodotus’ great innovation was to treat events as investigable: to gather accounts, weigh them, note contradictions, and admit uncertainty. Framing ignorance as evil elevates that practice from curiosity to civic duty. It’s also a quiet rebuke to power. Ignorance isn’t just personal; it’s political. Empires depend on managed narratives, on populations kept credulous, on enemies caricatured into inevitability. In that light, knowledge becomes a kind of resistance: not mere data, but hard-won understanding of causes, motives, and limits.
There’s subtextual humility too. For a writer famous for reporting multiple versions of the same story, “knowledge” can’t mean omniscience. It means the disciplined pursuit of better explanations, the willingness to revise, the refusal to let tradition substitute for evidence. Herodotus is betting that the moral life starts where certainty ends: in inquiry.
