John Keats

"My imagination is a monastery, and I am its monk."

"I am certain of nothing but the holiness of the Heart's affections and the truth of the Imagination."

"A thing of beauty is a joy forever."

"Nothing ever becomes real till experienced – even a proverb is no proverb until your life has illustrated it."

"Besides, a long poem is a test of invention, which I take to be the Polar star of Poetry, as Fancy is the sails - and Imagination the rudder."

"Praise or blame has but a momentary effect on the man whose love of beauty in the abstract makes him a severe critic on his own works."

"Heard melodies are sweet, but those unheard are sweeter."
