Modern Art?

“The Cubists are entitled to the serious attention of all who find enjoyment in the colored puzzle pictures of the Sunday newspapers. Of course there is no reason for choosing the cube as a symbol, except that it is probably less fitted than any other mathematical expression for any but the most formal decorative art. There is no reason why people should not call themselves Cubists, or Octagonists, or Parallelopipedonists, or Knights of the Isosceles Triangle, or Brothers of the Cosine, if they so desire; as expressing anything serious and permanent, one term is as fatuous as another.”
― Theodore Roosevelt, An Art Exhibition
