Nearly two hundred years ago, William Blake, the English poet, painter, and engraver, described vividly the contrasting responses of two groups of people to a tree: "The tree that moves some to tears of joy is in the eyes of others only a green thing that stands in the way. Some see nature all ridicule and deformity . . . and some scarce see nature at all. But to the eyes of the man of imagination, nature is imagination itself."
