If you were an octopus, would you view the world from eight different points of view? Nine? The answer may depend on how many brains an octopus has, or, to say it another way, whether the robust bunches of neurons in its coiling, writhing, incredibly handy arms bestow on each of them something akin to a brain. Is an octopus a creature ruled by a single consciousness centered in its large brain, or, by dint of its nerve-infused legs, a collaborative, cooperative, but distributed mind?
“Octopuses let us ask which features of our minds can we expect to be universal whenever intelligence arises in the universe, and which are unique to us,” Godfrey-Smith said. “They really are an isolated outpost among invertebrates. … From the point of view of the philosophy of the mind, they are a big deal.”
