You cannot make a bad poem good by voting on it, and passionate sincerity would not be accepted as qualification for a brain surgeon or a carpenter.
The work of great poetry is to aid us to become free artists of ourselves. Even Shakespeare cannot make me into Falstaff or Hamlet, but all great poetry asks us to be possessed by it.
To possess it by memory is a start, and to augment our consciousness is the goal.
The art of reading poetry is an authentic training in the augmentation of consciousness, perhaps the most authentic of healthy modes.
~ Harold Bloom, from The Art of Reading Poetry (Harper Perennial; March 1, 2005)
