To unsettle the existence of a God, it is only necessary to ask a
theologian to speak of Him; as soon as he utters one word about Him, the
least reflection makes us discover at once that what he says is
incompatible with the essence which he attributes to his God. Therefore,
what is God? It is an abstract word, coined to designate the hidden
forces of nature; or, it is a mathematical point, which has neither
length, breadth, nor thickness. A philosopher [David Hume] has very
ingeniously said in speaking of theologians, that they have found the
solution to the famous problem of Archimedes; a point in the heavens
from which they move the world.
