Coleridge and Wordsworth, especially in the late 1790s, are rather loosely thought of as having been primarily "nature poets." The matter will bear being looked into little further, however: how far did their views of nature converge, how far was there--as Coleridge later came to think concerning their views of poetry--a fundamental underlying disagreement? Coleridge was at that time making his name as a Unitarian preacher; he was thought of as a political and theological writer as much as a poet. It was Wordsworth who thought of him as a devotee of nature, addressing him in The Prelude as "one"
The most intense of Nature's worshippers,
In many things my brother, chiefly here
In this my deep devotion
How far, then, was "Nature" a subject of their conversations in 1798?
