I was strolling through the shelves of the library the other day and picked out a book titled “Global Brain” by Howard Bloom. The book’s premise—one I’ve heard before—is that individual life forms, whether they be bacteria or human, thrive by forming groups. All creatures, the book would seem to argue, are essentially social creatures. Hive or colony type creatures, like bees and ants, are especially demonstrative of this fact; they accomplish far more as a giant organism of many nodes (the individual bees and ants) than they would if they were all living separate lives.
This is true for humans as well. On one level, humans exist in societies. These societies seems to have a kind of meta-intelligence that decides to move towards democratic governments or embrace Justin Bieber. (Hmmm…) On another level, each human is really a collection of trillions of cells. Just as the decisions of a society emerge from the choices of individual humans, so to do the decisions of human individuals emerge from a chorus of cells. Your wants and needs and opinions are really the result of millions (or more) of votes. (At least this is what I think the book is gearing up to argue, as others have before. I’m only about five chapters in.)
This idea, that we as individuals are the result of many, seems both exciting and disconcerting. I don’t feel like a group, I feel like an individual. But we do have a certain sense of our compartmentalization. I say, “my stomach is telling me I’m hungry.” “My hand is tired after thumb wrestling for hours.” “My penis is aroused as it watches this naked woman walk by.” (A regular occurrence in my life.) The “I” that is the storyteller of our lives is being informed by other parts of the body. And even if we observe just the brain/mind, we can suss out how information kind of rises up to our top decision maker. We’re thinking of a way to solve a problem and the answer just arrives in a Eureka moment. Because a coterie of cells beneath our consciousness have been working at the problem and have arrived at an answer.
In theory, you could have some complex network of nodes, doing all sorts of calculations, without consciousness. That’s basically what we presume a computer to be doing: thinking (in a way) without being aware of it. But we humans have consciousness riding atop all this. Attention is a big part of it. When we are hungry our attention turns to our hunger. When we are horny our attention turns to our horniness. The conscious attention is what makes us feel like an individual as opposed to a million voters.
Which leads to that most perplexing of questions: what is consciousness?
