In paintings, music, poetry, architecture, we feel the elusive energy that moves through us and the air and the ground all the time, that usually disperses and turns chaotic in our busy-ness and distractedness and moodiness. Artists channel it, corral it, make it visible to the rest of us. The best works of art are like semaphores of our experience, signaling what we didn't know was true but do now.
