Blake, Self-portrait, 1802
You certainly mistake, when you say that the visions of fancy are not to be found in this world. To me this world is all one continued vision of fancy or imagination, and I feel flattered when I am told so.
I am happy to find a great majority of fellow mortals who can elucidate my visions, and particularly they have been elucidated by children, who have taken a greater delight in contemplating my pictures than I even hoped. Neither youth nor childhood is folly or incapacity. Some children are fools and so are some old men. But there is a vast majority on the side of imagination or spiritual sensation.
