I 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.
Philip LarkinAnd immediately Rather than words comes the thought of high windows: The sun-comprehending glass, And beyond it, the deep blue air, that shows Nothing, and is nowhere, and is endless.
