The poetic impulse is distinct from ideas about things or feelings about things, though it may use these. It's more like a desire to separate a piece of one's experience & set it up on its own, an isolated object never to trouble you again, at least not for a bit. In the absence of this impulse nothing stirs.
Philip LarkinI am not sure, once a poet has found out what has been written already, and how it was written - once, in short, he has learnt his trade - that he should bother with literature at all. Poetry is not like surgery, a technique that can be copied. Every operation the poet performs is unique, and need never be done again.
