William Blake

"Si las puertas de la percepción se depurasen,

todo aparecería a los hombre como realmente es: infinito.

Pues el hombre se ha encerrado en sí mismo hasta ver

todas las cosas a través de las estrechas rendijas de su caverna."

“If the doors of perception were cleansed every thing would appear to man as it is, Infinite. For man has closed himself up, till he sees all things thro' narrow chinks of his cavern.”

From The Marriage of Heaven and Hell
