"A little knowledge is a dangerous thing, but a little want of knowledge is also a dangerous thing"
About this Quote
The line works because it refuses the comfort of a clean moral. It’s not a warning against curiosity; it’s a warning against complacency in either direction. Butler was a Victorian contrarian who spent his career poking at piety, expertise, and received wisdom. In a culture intoxicated by scientific progress and confident moral certainties, he stresses that danger isn’t limited to the half-educated; it’s also baked into the social systems that keep people under-informed. The subtext: elites love to sneer at “a little knowledge” because it polices boundaries. But the cost of too little knowledge is not borne equally. The undereducated don’t just make worse choices; they get fewer choices, and they’re more exposed to manipulation by those who do possess expertise (or claim it).
Butler’s cynicism lands neatly in today’s information economy: partial knowledge breeds hot takes, but deliberate ignorance breeds conspiracies, scams, and political capture. His punchline is basically a diagnosis: the real hazard isn’t the quantity of knowledge, it’s the mismatch between what you think you know and what you need to know to act responsibly.
