This lecture presents the text of the speech about English poet William Wordsworth and the druids delivered by the author at the 2008 Warton Lecture on English Poetry held at the British Academy. It provides an analysis of the beginning of Book III of The Excursion and explains the concepts of the Poet, the Wanderer, and the Solitary. The lecture suggests that Wordsworth's characters inhabit a common land until modernity takes it away from them, and that this dissolves the natural regenerative seasonal cycle in which humans now find it so difficult to live and work.
