John Keats,
Keats: Poems Published in 1820
“ In the Ode on Melancholy Keats, in a more bitter mood, finds the presence, in a fleeting world, of eternal beauty the source of the deepest melancholy. To encourage your melancholy mood, he tells us, do not look on the things counted sad, but on the most beautiful, which are only quickly-fading manifestations of the everlasting principle of beauty. It is then, when a man most deeply loves the beautiful, when he uses his capacities of joy to the utmost, that the full bitterness of the contrast between the real and the ideal comes home to him and crushes him. ”
