A way of thinking about Dennett's theory of consciousness: a vote, and decision making.

I was just thinking about an article I wrote about here when I thought of a much better (and topical) metaphor for the way consciousness works in the human brain according to Daniel Dennett.

For the non-clickers:

(From Dennett:)

'"I claim that consciousness is not some extra glow or aura or "quale" caused by the activities made possible by the functional organization of the mature cortex; consciousness is those various activities. One is conscious of those contents whose representations briefly monopolize certain cortical resources, in competition with many other representations. The losers—lacking "political clout" in this competition—quickly fade leaving few if any traces, and that’s the only difference between being a conscious content and being an unconscious content."'

(From myself:)
"Basically, there is no "little man" of consciousness sitting in your brain, editing what comes in and then sending it up to "you," a separate medium, to become conscious content. It is the sum total of the activities of the neurological system that is consciousness itself.
"

It was the term "political clout" that got me thinking about this, along with a few weeks of staring at polls every day, and a metaphor popped into my head, more helpful perhaps than the negative example of the little man in explaining what (I think) Dennett means: the vote for president.

What Dennett is saying, with this analogy, would be, "the final determination of who becomes the next president of the United States (the outcome of the process, or "consciousness,") is not some extra capital "V" vote, (quale or aura,) it is the activities of millions of voters voting. This may seem like no more than a tricky accounting method, but the distinction is important. It is also fairly obvious when talking about a vote, but perhaps not so much when talking about our own consciousness. There is no president in your head, no controlling piece that decides what to do and what to show, what becomes conscious and what not, but millions of separate components all clamoring for attention (millions of voters with their own individual preferences and requirements.) When they reach a critical mass, they "monopolize certain cortical resources," and you become aware of something.

In fact, when we choose a president we are basically doing what everybody intuits we are doing
and what Dennett says we are precisely not doing: putting a "little guy" in charge of it all at the top of the head who makes the decisions. We choose an arbitrary point (the first Tuesday in November on a four-year cycle) to gather the input of all these little contributors, and then, ceremoniously and ritually assign, for the next four years, the one person that was able to align himself most broadly with the contributors, the voters, to the job of "decider."

There is some feedback, in terms of media and public opinion polls, but for the most part this is not what is happening in our brains: it's what we think is happening. What is really happening, according to Dennett, is more as if there were a constant election, not for a representative but on issues of state, and whenever a person decided to throw his or her vote in a different direction, her or she would do so, and whenever a voting level reached some critical threshold, it would be enacted, or changed, say, at 65% approval a new law would be passed, or at 30% disapproval something would be revoked.

In this way, the brain is a tyrannic democracy.

Some other random thoughts that sprang from this idea:

In this light it becomes much more apparent how ritualized government is, how we try to approximate power and make it more practical and benificial to the most people, and how that changes over time due to the evolution of social and religious (ritual) beliefs, as in how a King, standing in for God, makes decisions that are the best for everyone in the kingdom in aggregate top-down, versus how a president, standing in for a symbolic unity of the country and the opinions of the people, makes decisions informed by the will from below (the people) and not imposing them from above (this is an ideal, obviously a certain current president feels somewhat more like a king according to this way of thinking, at least at times.)

Similarly, what we call the "ego," is no more than a fiction we put in place as a shorthand way of understanding the millions of little bits of information inside, outside, and created in the relation between inside and outside. As noted in my earlier blog, this is why I think buddhist philosophy would be quite comfortable with Dennett's work.

This is why government is ritualistic, the ultimate power is never coming from it, it is legitimized only in so far as it reflects the will of God, or the will of the people, the ultimate powers. What we call the ego is a puppet standing in for the real thing, standing in for "will," (wherever you think that is coming from, an entirely different discussion) acting out ritually as if in a play. It is, first and foremost, an abstraction.

This idea of a threshold being met that changes everything is rather prevelent in nature, and seems to be one of the key ways in which things work. (Chronicled from a slightly different angle in Malcolm Gladwell's book Blink.) Neuron firings are a good example. Neurons constantly exchange ions coming in and out of their cell bodies, and electrical gradients are constantly changing, without triggering a change in the cell. But as soon as a critical charge is reached, as soon as the electrical gradient is overwhelmingly positive, for example, the electron fires.

Anyone who has watched a baby grow or learned something new him or herself (especially as an adult, when you tend to be more aware of these types of things) would likely be familiar with this as well. Practice (as discussed in the book Mastery) alternates between brief periods of incredible progress, followed by long plateus where nothing seems to change. I have noticed this playing the guitar, and also learning Chinese, as well as in practicing tai ji/ qi gong. Every day for four months it seems like I can't string two freaking sentences together, and then, as if by magic, two weekends ago, I'm babbling along without stopping, my accent got better exponentially, and my accessible vocabulary improved. I had, of course, been working on all of these things the whole time, but they didn't show any tangible improvement, or any steady improvement, until they all did all together all at once.

Think of it this way, perhaps: you are on a certain "level" of your practice, and there are 100 buttons. You need to push 70 of them to move on to the next level, but you also need to learn a certain technique to push each one individually, and learning each takes time and practice, and the buttons only stay depressed a certain amount of time. As you get better and better at pushing certain buttons individually, more and more stay depressed, until finally it "clicks," you've gotten 70 of the buttons depressed simultaneously and suddenly you're in a whole new world, you're on another level, and you have to start all over again exploring from here. Of course, on this new level, the options open to you are much much wider. And, of course, this is a only a silly analogy, though there may be some truth to it.

The worry about global warming stems from this idea. People aren't concerned that gradually, over the next hundred or two hundred years, things will change. Those concerned are worried because in a comparative instant, thousands of species will go extinct, the earth will become five degrees warmer, sea levels will rise in the meters, and floods will inundate lands. Again, not in isolated and separate incidents, but basically all together. The havok that this will wreck on civilization is one thing, but it may knock out the whole species. We just don't know, we don't know what will happen after the moment of change.

There's a variety pack for you to chew on.
