" But unless dualism or vitalism is true (in which case you have some extra, secret ingredient in you), you are made of robots—or what comes to the same thing, a collection of trillions of macromolecular machines. And all of these are ultimately descended from the original macros. So something made of robots can exhibit genuine consciousness, or genuine intentionality, because you do if anything does. "

― Daniel C. Dennett , Darwin's Dangerous Idea: Evolution and the Meanings of Life
