Who really said it

A little knowledge is a dangerous thing

Not Pope’s words — a misquote of “A little learning…” Alexander Pope 1688–1744 · English poet & satirist
Disputed Free to reuse

The thought is genuinely Pope’s, but he wrote “A little learning is a dang’rous thing” in An Essay on Criticism (1711) — not “knowledge.” The “knowledge” wording is a later paraphrase that hardened into a catchphrase; it appears nowhere in Pope’s poem.

A little Learning is a dang’rous Thing;
Drink deep, or taste not the Pierian Spring:
There shallow Draughts intoxicate the Brain,
And drinking largely sobers us again.

Part II of An Essay on Criticism. Pope’s word is “learning” — superficial study — not “knowledge.”

How we verified this

  • Pope’s original couplet reads “A little learning is a dang’rous thing” in the Project Gutenberg text of An Essay on Criticism — the word is learning, not knowledge.
  • Quote Investigator traces how the “knowledge” variant grew out of Pope’s line, quoting Thomas Henry Huxley (1877): “The saying that a little knowledge is a dangerous thing is, to my mind, a very dangerous adage.”
  • By Huxley’s day the “knowledge” catchphrase was already common enough to argue against — evidence the swap is a genuine, long-standing paraphrase of Pope, not his own phrasing.
Public domain

Pope’s An Essay on Criticism was first published in 1711 and is long in the public domain in the United States. (The popular “knowledge” rewording is an anonymous later paraphrase, not a separate copyrighted work.)

Fact-check

Often misattributed

This is one of the most common misquotations in English — the wording people cite is not quite what Pope wrote.

Alexander Pope (the real line) Misquote

Pope wrote “A little learning is a dang’rous thing” in An Essay on Criticism (1711). The popular “a little knowledge is a dangerous thing” substitutes a word he never used in that line.

Anonymous later usage Variant

The “knowledge” form spread as a proverb through the 1800s; by 1877 Thomas Henry Huxley was already pushing back on it, per Quote Investigator. No single author owns the reworded version.

The thought is Pope’s and the couplet is real — but the accurate quotation is “A little learning is a dang’rous thing,” per the original text.

Context

Why it mattered

Pope’s point is subtle: a little learning is worse than none because it breeds false confidence. The next lines make the metaphor — shallow sips from the Pierian spring (sacred to the Muses) “intoxicate the brain,” while drinking deeply sobers you again.

The swap to “knowledge” flattens that meaning. Learning is the process of study; knowledge is the result — which is exactly why Huxley objected that some knowledge, however small, is better than none.

“A little learning is a dang’rous thing; / Drink deep, or taste not the Pierian spring.”

About Alexander Pope
