“Beauty is truth, truth beauty,—that is all / Ye know on earth, and all ye need to know.”

About this quote
Keats puts the claim in the mouth of the Urn, which keeps beauty frozen and therefore flawless, and then lets the speaker insist that the real, changing, ugly and beautiful world is preferable. It is the most quoted line in English poetry about what draws one person to another.
