University of Chicago Biochemist: All Living Cells Are Cognitive
James Shapiro’s recent paper points out, with examples, that bacteria meet the Oxford English Dictionary’s definition of “cognitive”University of Chicago biochemist and evolutionary biologist James Shapiro has a message that those who believe that consciousness is an illusion (as, for example, philosopher Daniel Dennett claims) should heed: If all living things are “cognitive” then, to what extent would life itself have to be an illusion?
