There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first truth is science, and the second is art. Neither is independent of the other or more important than the other. Without art science would be useless as a pair of high forceps in the hands of a plumber. Without science art would be a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from being ridiculous.
