...why did Plato say that ...

...why did Plato say that poets should be chased out of the republic?  Precisely because every poet and every artist is an antisocial being.  He\'s not that way because he wants to be; he can\'t be any other way.... and if he really is an artist it is in his nature not to want to be admitted, because if he is admitted it can only mean he is doing something which is understood, approved, and therefore old hat - worthless.  Anything new, anything worth doing, can\'t be recognized.
