Reason, or the ratio of all we have already known, is not the same that it shall be when we know more. - William Blake

"Piping down the valleys wild
Piping songs of pleasant glee
On a cloud I saw a child.
And he laughing said to me.

Pipe a song about a Lamb;
So I piped with merry chear,
Piper pipe that song again — So I piped, he wept to hear.

Drop thy pipe thy happy pipe
Sing thy songs of happy chear,
So I sung the same again
While he wept with joy to hear

Piper sit thee down and write
In a book that all may read — So he vanish'd from my sight.
And I pluck'd a hollow reed.

And I made a rural pen,
And I stain'd the water clear,
And I wrote my happy songs
Every child may joy to hear.

- "Introduction to the Songs of Innocence

If the doors of perception were cleansed, everything would appear to man as it is - infinite.

To Mercy, Pity, Peace, and Love All pray in their distress; And to these virtues of delight Return their thankfulness. For Mercy, Pity, Peace, and Love Is God, our father dear, And Mercy, Pity, Peace, and Love Is Man, his child and care. For Mercy has a human heart, Pity a human face, And Love, the human form divine, And Peace, the human dress.
