my flatmate said keats 'negative capability' in a reading context is like coleridge's 'suspension of disbelief': i think coleridge was referring to poems like 'the ancient mariner'- thinking his readers might find it unbelievable - the two concepts i think were probably closer in their coiners time .. (now we'll believe anything). what im interested in is that keats theory has conservative critical respect, yet the same critic can dismiss poetries that negative capability could most readily apply to from a reading perspective.. all of this is just to say you can open yourself to 'duty' (to poetry) - just read - youll find your mind will appreciate the poetry as long as theres not a constant chatter in yr head of 'whats this mean' 'i dont get it' etc. those comments are like people talking during a reading ..
