When I think of Coleridge, I think of those momentary sparks of intuition I have experienced, when my brain seemed to grasp a clear and divine truth. It's like seeing something from the corner of my eye; when I turn to look more closely - it's gone! If others do not share this impression, that is all right, because subjectivity was a major tenet of the Romantic Movement, of which Coleridge was a founding member.
The Romantic Movement was, in part, a rejection of the cold logic that came from the Age of Reason. Romantics such as Coleridge, Wordsworth, and Southey emphasized emotion over reason, feelings over intellect. It was a return to spiritual, ephemeral realms of the imagination, often involving legends and heroes from ancient times. While their writing seems quite structured by today's standards, they were actually breaking away from the strict rules of verse prescribed by earlier poets.
