Part II, lines 215–216

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.

Pope’s point is that a smattering of study is more dangerous than none, because it breeds false confidence — the cure is to “drink deep” from the Pierian spring, the classical fountain of the Muses.

How we verified this

  • The line opens the second part of Pope’s An Essay on Criticism, first published anonymously in 1711.
  • Wikipedia records the original as “A little learning is a dang’rous thing” and notes it is “frequently paraphrased as ‘A little knowledge is a dangerous thing’” (source).
  • Quote Investigator quotes Pope’s couplet verbatim while untangling a separate, later saying about “false knowledge.”
  • Word historians at Phrases.org.uk trace the “knowledge” swap to an 18th-century misquotation of Pope.
Public domain

An Essay on Criticism was first published in 1711, so both the poem and this line are firmly in the public domain in the United States (any work published before 1931 is PD in 2026).

Fact-check

Often misattributed

The attribution to Pope is correct — the trouble is the wording, which is very often altered or handed to the wrong person.

“A little knowledge is a dangerous thing” Misquote

Pope wrote “learning,” not “knowledge.” The “knowledge” version is a paraphrase that took hold through 18th-century misquotation and is now more common than the original (Phrases.org.uk).

Francis Bacon Related idea

Bacon expressed a kindred thought about shallow versus deep study in his essay Of Atheism (1601), and the idea is sometimes traced to him — but the memorable line itself is Pope’s (Phrases.org.uk).

Genuinely Pope, from An Essay on Criticism (1711) — but the original word is “learning,” and the spelling was “dang’rous.”

Context

Why it mattered

Pope was barely 23 when An Essay on Criticism appeared, a verse manifesto on how to judge literature. The line sits at the head of its second part, warning would-be critics that a shallow acquaintance with learning is worse than none: it produces confident fools.

The poem is a quarry of familiar English phrases — “To err is human, to forgive divine” and “Fools rush in where angels fear to tread” also come from it — which is part of why this line has stayed in circulation for three centuries.

Drink deep, or taste not the Pierian spring.
