I feel that a man may be happy in This World. And I know that This World is a World of Imagination & Vision. I see Every thing I paint in This world, but Every body does not see alike. To the Eyes of a Miser a Guinea is far more beautiful than the Sun, & a bag worn with the use of Money has more beautiful proportions than a Vine filled with Grapes. The tree which moves some to tears of joy is in the Eyes of others only a Green thing which stands in the way. Some see Nature all Ridicule & Deformity, and by these I shall not regulate my proportions; & some scarce see Nature at all. But to the Eyes of the Man of Imagination, Nature is Imagination itself. As a man is, so he sees. As the Eye is formed, such are its Powers.

-William Blake
