"Beauty is truth, truth beauty,—that is all
Ye know on earth, and all ye need to know." Keats
This final line of the poem, "Ode On a Grecian Urn" by Keats is an appropriate summation of the whole. The deep truth reminds us that beauty can guide us to truth, and truth can be known and found through beauty. It's interesting that, in addition to this being all we need to know on earth, he says it is all we need to know, period. It's the intimation of something beyond this existence. It's a reassurance that even beyond earth, this guiding principle still stands.
