"Errors, to be dangerous, must have a great deal of truth mingled with them. It is only from this alliance that they can ever obtain an extensive circulation"
About this Quote
Dangerous falsehoods rarely arrive wearing a villain’s cape; they show up dressed as plausible common sense. Sydney Smith’s line lands because it treats “error” not as an absence of truth but as a parasitic strategy that feeds on it. The real menace isn’t the obvious lie, which collapses under casual scrutiny. It’s the half-right claim that flatters what people already suspect, then quietly smuggles in the extra step that doesn’t follow.
Smith was a clergyman and a public intellectual in an age of pamphlets, pulpit politics, and reform battles, when ideas moved fast through sermons, newspapers, and tavern talk. His word choice matters: “alliance” makes truth and error sound like political partners, a coalition formed for reach. “Extensive circulation” is basically an early diagnosis of virality: what travels furthest is what can be repeated without effort, what feels confirmatory, what can be quoted.
The subtext is a warning to moral and civic gatekeepers (including himself). If you want to fight a harmful belief, you can’t just shout “false.” You have to identify the true fragment that gives it credibility, then separate that fragment from the conclusion hitching a ride. Smith also punctures the comforting idea that only gullible people fall for bad ideas. The mechanism he’s describing works precisely because it recruits the rational impulse: we spot something accurate, assume the rest deserves the same trust, and move on.
It’s a brisk, cynical bit of Enlightenment-era media literacy: truth is not only a virtue; it’s also the best camouflage.
