Penrose, with his co-collaborator, anesthesiologist Dr. Stuart Hameroff, declared: “We conclude that consciousness plays an intrinsic role in the universe.”

Turin concludes from this that consciousness is not an emergent property of the complex nervous systems of higher animals, but is something more fundamental that works at the level of cells.

It is often suggested that the brain may be a quantum computer,

It doesn’t seem particularly compelling. One source of evidence is work by Suzana Herculano-Houzel, a neuroscientist who has dissolved the brains of many creatures to determine how many neurons are present. She’s found a lot of interesting scaling laws. She has a paper discussing the human brain as a scaled-up primate brain.60 Across a wide variety
