Peter Redgrove said this quote

His (Samuel Coleridge) dark senses were constantly in play, the frustration of them bringing illness. Weather and organic nature combined in a synaesthetic multi-media event, and this was the ground of all perception before it was divded up in daily living: the Primary Imagination giving way to the Secondary. Poetry was forever seeking a conscious return to this state, which existed all the time, whether he knew it or not.
