How does one happen to write a poem: where does it come from? That is the question asked by the psychologists or the geneticists of poetry.
There is probably nothing wrong with art for art's sake if we take the phrase seriously, and not take it to mean the kind of poetry written in England forty years ago.
In a manner of speaking, the poem is its own knower, neither poet nor reader knowing anything that the poem says apart from the words of the poem.
Serious poetry deals with the fundamental conflicts that cannot be logically resolved: we can state the conflicts rationally, but reason does not relieve us of them.
Narcissism and the Confederate dead cannot be connected logically, or even historically; even were the connection an historical fact, they would not stand connected as art, for no one experiences raw history.
Other psychological theories say a good deal about compensation.
Poets, in their way, are practical men; they are interested in results.
Religion is the sole technique for the validating of values.
Genetic theories, I gather, have been cherished academically with detachment.
