Keats's letters have long been regarded as an extraordinary record of poetic development. According to T. S. Eliot, Keats's letters are "the most notable and most important ever written by any English poet." They represent one of the most sustained reflections on the poet's art we have from any of the major English poets. Yet quite apart from the light they throw on the poetry, they are great works of literature in their own right. Written with gusto and occasionally painful candor, they show a powerful intelligence struggling to come to terms with its own mortality. Sometimes bitterly jealous in love and socially and financially insecure, at others playful and confident of his own greatness, Keats interweaves his personal plight with the history of a Britain emerging from the long years of the Napoleonic Wars into a world of political unrest, profound social change, and commercial expansion.
