But whereas in nature we are attracted by the sense of a guiding hand even when there is none, in art the analogy is reversed: we are attracted to products of a guiding hand where the hand itself has become invisible. For a work of art whose artistry is too evident loses its ability to cause wonder; it becomes staid and predictable. In both art and nature, we see beauty in signs of purposiveness without purpose, natural artistry—but with an important difference. Whereas in nature we supply the artist, in art we supply the sense of its naturalness, that it was produced without evident artifice.
