As to your Newton, I confess I do not understand his void and his gravity; I admit he has demonstrated the movement of the heavenly bodies with more exactitude than his forerunners; but you will admit it is an absurdity to to maintain the existence of Nothing.
Letter 221 to Voltaire on November 25, 1777. "Letters of Voltaire and Frederick the Great", translated by Richard Aldington, 1927.
