Waterhouse: "Now, if you--the ingenious Dr. Leibniz--contrive a machine that gives the impression of thinking--is that really thinking, or merely reflecting your genius?"

Leibniz: "You could as well have asked: are we thinking? Or merely reflecting God's genius?"

Waterhouse: "If we are mere mechanisms, obeying rules laid down by God, then all of our actions are predestined, and we are not really thinking."

Leibniz: "This is one of the two great labryrinths into which human minds are drawn: the question of free will versus predestination. You were raised to believe in the latter. You have rejected it--which must have been a great spiritual struggle--and become a thinker. You have adopted a modern, mechanical philosophy. But that philosophy now seems to be leading you back towards predestination."
