"Great art is clear thinking about mixed feelings," said John Baldessari, and before him, W.H. Auden wrote, "Poetry might be defined as the clear expression of mixed feelings." The great artist has what Auden called "the gift of double focus," and what Keats called "negative capability" — an ability to see things through different lenses, to not only deal with uncertainty, but to use it as the fuel for one's work.
