"All men are liable to error; and most men are, in many points, by passion or interest, under temptation to it"
About this Quote
The second clause sharpens the blade: “most men” aren’t merely mistaken by accident; they’re nudged, steadily, by “passion or interest.” Locke is pointing at the machinery that manufactures belief. People don’t just arrive at wrong ideas; they’re recruited into them by desire, fear, loyalty, pride, money. “Temptation” is a moral word, but he uses it to describe cognition, implying that thinking is a field of ethical risk. Your mind is not a neutral instrument; it has appetites.
The subtext is institutional. This is a case for humility as a civic technology: toleration, open debate, limits on power, and procedures that assume bias. In a Europe still haunted by religious wars and authoritarian claims to certainty, Locke’s skepticism isn’t fashionable detachment; it’s damage control. He’s arguing that since error has incentives, we need structures that reduce the payoff for self-serving certainty and make correction possible without bloodshed.
