"To hold, as 'twere, the mirror up to nature." — Shakespeare

Francis Bacon was involved with building in the human mind 
a replica of the great globe-the earth itself. He was intent 
on holding the mirror up to nature, and the mirror he held
up to nature was the human mind. Bacon wrote :

"God hath framed the mind of man as a glass capable
of the image of the universal world, joying to receive
the signature thereof as the eye is of light."

Bacon's mirror was a crystalline globe, and Bacon called 
his model of the world-The Intellectual Globe.
