We can give an octopus IQ tests of various sorts, and Godfrey-Smith says such experiments have been run. An octopus, for example, can learn to unscrew a jar to get the food it contains. As the researcher reports, an octopus even figured out how to turn off lights by squirting water to short-circuit the power supply. Got to be some intelligence there. Just don’t really understand what’s behind it. You know, a “mind.”
Reportedly, an octopus can even distinguish among aquarium keepers and—this is a bit strange—can even develop a dislike for certain individuals, showing dislike by squirting water on the keeper. Ah! The anecdotes are like tales from science fiction writers. We listen to them and shake our heads. Is this our imagination at work, an imposition of human characteristics to convince us that we understand what is going on? Or can these animals really purposefully do what people report they do? The key word: Purposefully. You’ve got a problem if you are the aquarium keeper and your octopus hates you on purpose. How can you convince it that you are a lovable, though alien, creature?
Back to Godfrey-Smith’s statement, the one that I believe acknowledges a profound discovery. “There is no single scale….”
What is the significance that intelligence of some kind evolved differently from our own? These eight-armed mollusks seem to bear little-to-no-resemblance to “our” kind of life, but, of course, we have a tendency to see things through human analogs. Thus, we draw conclusions that associate our behavior with that of other animals. We know, however, that we share no similar brain structure with the octopi as we do with other vertebrates, and that makes our own misunderstandings all the more strange. Sharing a brain structure doesn’t seem to give us any more access to another vertebrate mind than the limited access we have to the mind of a cephalopod.
So, how do we deal with not just another kind of brain, but also with what the author calls “mind”? Is “mind” even understandable when we consider the brain? When we look at “intelligent” birds, dogs, or elephants, do we have any real understanding of their “minds”? Sure, we have some clues: A wagging tail, a show of teeth, a snarl, a certain posture. Maybe these outward signs reveal a probable intention. But do they reveal “mind”? And in the outward signs of our fellow humans do we see a true revelation of “mind”?
Are we capable, even with our similarly structured brains, of sensibly measuring each other’s minds? Sure, we can map the brain, categorize behavior, trace the biochemistry of memory and emotion, and devise tests that purportedly measure “intelligence,” and we can piece all these together into a puzzle we call “mind.” But the puzzle is always missing crucial pieces.
So, when we run into the unexpected, say a behavior such as suicide by one who seemed “happy” or debilitating addiction by one who seemed to have everything, what understanding do we reach about the mind behind the brain and its manifest behavior? Or when we run into apparently motiveless malignity, do we have any real explanations other than to call such a mind “evil,” “warped,” or “pathological”?
If by spitting at one aquarium keeper and not another an octopus with 500 million scattered neurons befuddles a human with 100 billion localized neurons, is there hope that we will ever reach an understanding of another 100 billion neurons whose cumulative and cooperative work generates a “mind” separate from our own?
There might be, however, some instances of a “meeting of minds” that is, in itself, not comprehensible and not measureable. Two people “of one mind” act at least briefly in unison. Moments in sports between or among teammates, moments in military action, moments in times of catastrophe, all “heightened” moments, and moments in “love” somehow join “minds.” Strangers become one. Separate organisms join in ways that cannot be quantified.
Maybe those 500 million neurons in an octopus somehow allow it to sense the mind of an aquarium keeper. Maybe an octopus can read something it doesn’t like in one and does like in another human. Maybe in that perception there is a meeting—albeit in dislike a negative one—of minds between brains that evolved along different paths. Or maybe there’s just some bit of instinct that isn’t “mind,” but rather is a reaction to a stimulus as simple as magnetotactic bacteria sensing north and south in a magnetic field. Tough call.
So, some people like you, and others don’t. Good luck in figuring out why in either case. To do so means understanding mind.
Practical application: Is there any relationship between the foregoing musings and current or past events? Am I suggesting that the above applies, for example, to reactions to the 2016 American election? Just read my mind, but please don’t squirt water on me as I walk past the tank.
