For the common distinction between good and evil, Blake substitutes the distinction between imagination and reason; and reason, the rationalizing, measuring, comparing faculty by which we come to impute praise or blame is the only evil in his eyes.

"There is nothing either good or bad but thinking makes it so;" to rid the world of thinking, to substitute for reason, imagination, and for thought, vision, was the object of all that he wrote or drew.

The implications of this philosophy carry far, and Blake was not afraid to follow where they led him.

Fortunately for those who hesitate to embark on that dark and adventurous journey, his work contains delightful and simpler things.

He wrote lyrics of extraordinary freshness and delicacy and spontaneity; he could speak in a child's voice of innocent joys and sorrows and the simple elemental things.
