Other Minds: The Octopus, the Sea, and the Deep Origins of Consciousness
by Peter Godfrey-Smith
Peter Godfrey Smith writes that studying the octopus is probably the closest any of us will get to studying the alien mind. He poses questions: what makes a life sentient, why do cephalopods (octopus, cuttlefish and squid) exhibit a wild range of colors and patterns—are the patterns thought, mood or communication? I finished the book not really certain of any answers regarding these fascinating animals, but content to live with the questions.
