One problem with visual art is that its language is based on space and time, and how one reacts to an image is based on his experience of space and time, most of all on the connections his memories make between scenes, events, and feelings.
I'll go Rob one better and submit that the most powerful art, the one most able to produce a transcendental flash not dependent on space, time, and experience, is music. Music is completely abstract, and therefore, universally powerful.
Before you jump off in the wrong direction by pointing to the noise people nowadays incorrectly call music, let me explain that I'm talking about actual music: not rock, rap, or any of their predecessors or disoriented derivatives. Mozart will do, as will Beethoven or Chopin or Mendelssohn, or Rachmaninoff, or more recently, Barber, or the greatest of them all, Giacomo Puccini. Each of these guys can stab you in the heart, and you can't explain where the stab came from.
