'The Invisible World' originates from one of the great Romantic scholars of our time. The ten chapters are each transcriptions of a lecture given by Jonathan Wordsworth at the Wordsworth Summer Conference or Wordsworth Winter School which have been edited and annotated. There are detailed assessments of the poetry of Blake, Wordsworth, Coleridge and Keats with references to Shelley and Byron. Central 'Romantic' questions are addressed such as: What did Romanticism consist of? What was the Romantic Imagination? How did Wordsworth engage with the French Revolution? How did Wordsworth engage with women? What was the importance of Ossian and Burns? How does an eccentric writer like Blake fit into 'Romanticism'? What do the great Romantic poets have in common? How far is Coleridge indebted to Cowper in 'Frost at Midnight' and how does his own poem aspire beyond the limits of Cowper's vision? What was the Excursion and why is it important? How is Wordsworth's poetry 'transformative'? What was particular about Keats's Imagination? How can Blake be said to have had the first theory of Imagination? The book is divided into ten chapters: 1. 'Revolutionary Wordsworth' asks in what ways is Wordsworth a 'revolutionary poet'? 2. 'What is The Excursion?' is a look at the origins and evolution of that book as well as pointing to its special qualities. 3.'Sympathetic Imagination' asserts that Wordsworth is just as capable as Keats of being the 'chameleon poet' and examines his poems of the mother-child relationship from 'Lyrical Ballads'. 4. 'Keatsian Imagination' is an extensive inquiry into Keats's theory of the Imagination and his practice as a poet. 5. 'Double Bicentenary' analyses the importance of Macpherson's Ossian and Burns to Romantic poetry and particularly to Wordsworth. 6. 'Doors of Perception' explores the theories of Imagination held by many of the Romantic poets and compares them. 7. 'Two Strangers and a Pair of Wild Eyes' discusses Coleridge's debt to Cowper's 'The Task' in detail in 'Frost at Midnight' and how he enlarges the scope of his own poem to embrace the 'Primary Imagination'. 8. 'Blake and the Imagination' selects five central passages from Blake's 'Marriage of Heaven and Hell', 'Milton', 'Europe' and 'Jerusalem' to discuss how Blake thought of the Imagination. 9. 'Wordsworthian Transformations' is an in depth examination of how Wordsworth transforms his materials for specific Wordsworthian purposes including transformations of the biblical sublime, Miltonic epic, Burger's Gothic ballads and ideas of childhood in the 'Immortality Ode'. 10.'Understanding Blake and the First Book of Urizen' offers the reader a detailed examination of that book as well as a general method of how to read Blake and how to value him.
