According to Carl Sagan and Ann Druyen's book, Shadows of Forgotten Ancestors (p. 70), "One of Huxley's interests had been the idea that all animals, including us, were 'automata,'  carbon-based robots, whose 'states of consciosuness... are immediately caused by molecular changes of the brain-substance.'  Darwin closed his last letter to him with the words:  'Once again, accept my cordual thanks, my dear old friend.  I wish to God there were more automata in the world like you.' "
