From: The Marriage of Heaven and Hell (1793) by William Blake (UK, 1757 - 1827)

I then asked Ezekie: why he eat dung, & lay so long on his right & left side? He answerd, the desire of raising other men into a perception of the infinite; this is the North American tribes practise.
& is he honest who resists his genius or conscience. only for the sake of present ease or gratification? The ancient tradition that the world will be consumed in fire at the end of six thousand years is true, as I have heard from Hell.
For the cherub with his flaming sword is hereby commanded to leave his guard at tree of life, and when he does, the whole creation will be consumed, and appear infinite and holy whereas now it appears finite & corrupt.
This will come to pass by an improvement of sensual enjoyment. But first the notion that man has a body distinct from his soul, is to be expunged. This I shall do, by printing in the infernal method, by corrosives, which in Hell are salutary and medicinal, melting apparent surfaces away, and displaying the infinite which was hid.
If the doors of perception were cleansed every thing would appear to man as it is, infinite. For man has closed himself up, til he sees all things thro' narrow chinks of his cavern.
