Who said a little knowledge is a dangerous thing?

Answer 1

Alexander Pope (1688 - 1744) wrote 'An Essay on Criticism' in 1709. In it he wrote:

"A little learning is a dangerous thing; drink deep, or taste not the Pierian spring: there shallow draughts intoxicate the brain, and drinking largely sobers us again." The modern meaning translates to mean that people with a small amount of knowledge often think that they have more 'expertise' than they really do. Sometimes, when this percieved 'expertise' translates into action, it can result in unpredictable, or even tragic consequences.

Answer 2

The correct phrase is, "A little learning is a dangerous thing." Used by St. John Chrysostom (c. 347-407):

"A little learning is a dangerous thing, because it makes those who have it unwilling to learn more. The unlearned are more open to conviction, because they are not so foolish as to think that they are wise."

Citation has "1 12:23" which I presume means the first series (two were printed, each containing 14 volumes), vol. 12, page (or section?) 23 - as quoted in: T. Oden and G. Bray, eds., Ancient Christian Commentary on Scripture, New Testament Vol. VII, 1-2 Corinthians. Downers Grove, Ill.: InterVarsity Press, 1999, p. 17, in reference to I Cor. 1:26.

Answer 3

This quote is attributed to Alexander Pope, a famous English poet from the 18th century. The full quote is "A little learning is a dangerous thing; drink deep, or taste not the Pierian spring." It highlights the idea that having only a superficial understanding of something can lead to misguided actions or conclusions.
