Daily Inspiration Quote by William Kingdon Clifford

"It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence"

About this Quote

Clifford doesn’t argue for skepticism; he tries to criminalize credulity. The line is built like a theorem: absolute scope ("always, everywhere, for anyone") plus a hard prohibition ("wrong") plus a single condition ("insufficient evidence"). That mathematical casing is the point. He’s smuggling a moral law into epistemology, turning belief from a private hunch into a public act with consequences. In Victorian Britain, where religious certainty still carried social prestige and new sciences were steadily eroding inherited doctrine, that move was a cultural provocation: faith isn’t merely mistaken, it’s ethically negligent.

The subtext is surprisingly political. Clifford’s famous example (a shipowner who convinces himself an unseaworthy vessel is fine and it sinks) frames belief as a rehearsal for action. Even if nothing bad happens, the shipowner is still guilty because he trained himself to accept comforting stories. Clifford treats that mental habit as social pollution: credulous people create a marketplace for fraud, demagoguery, and superstition. Belief, in his view, is part of the commons.

The rhetorical genius is its austerity. No appeals to personal authenticity, no concession to "meaning", no cozy separation between heart and head. It’s a Victorian version of "do the work" - except the work is epistemic hygiene. The cost is baked in: he leaves little room for trust, intuition, or the ordinary leaps that make relationships and moral commitments possible. That severity is why it still stings; it reads less like advice than like indictment.
