public and private

These two poles of outward and inward transformation are the Romantic extremes: Shelley's claim that the poets are unacknowledged legislators, Keats's cry, "oh for a life of pure sensation". Keats saw that Shelley's wish to vivify the language of noble reason, so that it would incite men to make a just world, could lead only to the surrender of hidden poetic gardens to public planners; Keats wrote poems like arbors, in which readers were invited to spend a lifetime eating imaginary nectarines from imaginary dishes.
