Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness

3/5. A philosopher and avid diver tells us at length about various cool things regarding octopus and cuttlefish cognition. It's all by way of making the interesting argument that cephalopods have evolved consciousness – with a digression into what that means – on an entirely separate track from us. So they are the closest we will probably ever get to encountering alien sentients. It's cool stuff which I mostly read while lying on assorted Bermudian beaches and poolsides, because this is what I read to relax. This book does not really get into what octopus consciousness tells us about our own, which is what I was hoping for; it's more of the "gee isn't that neat!" school. It is pretty neat, though.
