"For Blake the imagination is nothing less than God as He operates in the human soul…. for Coleridge the imagination is of first importance because it partakes of the creative activity of God.

This is a tremendous claim, and it is not confined to Blake and Coleridge. It was to some degree held by Wordsworth and Shelley and Keats. Each was confident not only that the imagination was his most precious possession but that it was somehow concerned with a supernatural order. Never before had quite such a claim been made, and from it Romantic poetry derives much that is most magical in it."

–C. M. Bowra, The Romantic Imagination (1949)
