Would Cognition in Bacteria “Dethrone” Humans?

A cognition researcher’s approach to the question helps account for the growing popularity of panpsychism — as an alternative

Adelaide University cognition researcher Pamela Lyon offered an interesting thesis at Aeon last month: “Cognition did not appear out of nowhere in ‘higher’ animals but goes back millions, perhaps billions, of years.” Given that several scientists have recently made claims for cognition in single-celled entities, her contention is not all that surprising. But her approach to the topic prompts some thought: Lyon, who has little time for doubters, invokes Charles Darwin in calling for a “Copernican” shift in thinking on the subject: In On the Origin of Species (1859), Charles Darwin draws a picture of the long sweep of evolution, from the beginning of life, playing out along two fundamental axes: physical and mental. Body and mind. All living beings,…

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? Something’s wrong there. Let’s follow the thread of what Shapiro is saying. He takes a simple approach: If bacteria and archaea, thought to be the oldest, simplest life forms from at least 2 billion years ago, can be shown to have cognitive processes, then it stands to reason that most (if not all) of the more complex life forms have them too: All living cells sense and respond to changes in external…
