When people cease to use art , they will become aware
of its beauty ( I didn't say feel , because it's up for debate ) . People now use the music of Bach or Beethoven as a background in a restaurant or listen to their masterpieces in the car or while doing other jobs , most people use paintings as a decorative element in a room or an office , others use poetry for I don't know what purpose ...
For such a kind of organic beings
the claim " art for art's sake " can be radical or nonsense . Isn't poetry a branch of art ?
A poet (the good one in my humble opinion ) puts in words what a painter puts ( in some cases cannot ) on canvas , and organizes his words exactly the same way a composer do with his notes
Poetry for poetry's sake ??!! why not ?!!
