For what do we truly know, or what can we clearly affirm, of any one of those important things upon which all our reasonings must of necessity be built--time and space, life and death, matter and mind?

Observation made in the cloister or in the desert will generally be as obscure as the one and as barren as the other; but he that would paint with his pencil must study originals, and not be over-fearful of a little dust.
