John Keats was an idealist to whom concepts such as Truth, Beauty and Imagination were both real and important. His writings are accompanied by an awareness that his time as a writer might be short, and reveal an engaging personality, full of humour and enjoyment of life.
Work of the principal of the Romantic movement of England received constant critical attacks from the periodicals of the day during his short life. He nevertheless posthumously immensely influenced poets, such as Alfred Tennyson. Elaborate word choice and sensual imagery characterize poetry, including a series of odes, masterpieces of Keats among the most popular poems in English literature. Most celebrated letters of Keats expound on his aesthetic theory of "negative capability."
