Reflection 113: Information

June 8, 2009

(Copyright © 2009)

If it is true that there is no little homunculus in our heads enjoying the passing parade, it is equally true that there is not even a parade. As for representations of a parade, there are a great many (on the order of at least a 100 in any given brain), all dealing with different aspects of the parade, but there is no one street corner or theater where the float of Humpty Dumpty, say, passes by drawn by six white horses in living Sense-Surround.

Mr. Dumpty is represented by action potentials, ions streaming through membrane channels, neurotransmitters flowing across synapses, some degree of synchrony between neurons firing in different brain modules, and so on, none of which can account for the representation (or illusion) of reality, much less for reality (the parade) in-and-of itself.

Yet we keep talking about the brain as an “information processor,” as if information from the world somehow gets into our heads and forms a representation that can be taken for the world itself. Ionic or chemical signals (suggestive of patterns of energy), yes; information, no. As for interpreting such signals, each and every brain is on its own in that regard. Those signals mean to us solely what our respective minds take them to mean. Our surroundings provide patterns of energy, we map our understanding of what they might mean on those patterns.

We interpret patterns of energy from our surroundings as clues to the situation we are in at the moment, then interpret that situation as meaningful from our point of view based on our investment in that situation. Which varies, depending on how we choose to regard it. Our minds deal in the currency of conjecture and speculation, not information (as if the meaning were determined beforehand by an unidentified agent who is not in our head).

Which is not what we commonly assume or even read in some neural science textbooks. It is easier to assume information enters the brain through the senses, is coded in terms of patterns of neural activity, and is magically “represented” in one form or another, then interpreted by the mind—interpreted to have the same meaning it had on the far side of any sensory apparatus, without giving an account of how such a miracle could happen.

Energy is not meaningful in and of itself. And it is energy, not information, that impinges on our senses. Interpretation requires a context—some sort of situation within which energy takes on meaning in reference to relationships characterizing that situation. And it is no easier for situations to enter consciousness through the senses than it is for information or “reality” to make the same journey. For us, situations exist in terms of relationships between traces of brain activity, which means we derive them from ionic and molecular flows in various modules in our heads. A pretty neat trick.

Yet everyday wisdom has it that there is a one-to-one correspondence between what goes on in the world and what goes on in the minds of those who live in the world. It would be far more accurate to reverse that depiction and say that the world has no existence other than that extended to it by the minds in which it lives. For the world, in fact, does live in us and not vice versa. When we die, our versions of the world also die. Based on a few selected patterns of energy flow impinging on our senses, we project our hypothesis that the world is in such-and-such a state onto those patterns—voila! the “real” world.

That is, contrary to our naive assumptions, the world reflects to us representation we concoct in our minds consistent with the few patterns of energy flow we take the trouble to interpret. What is real is the world in our heads, the subjective (meaningful) world that guides our behavior. That other (outer) world is largely a mystery to us. We inform it according to our preferences at the moment. Information flows outward as mapped onto energy flows which are inherently meaningless until interpreted; interpretation takes place in the mind (ours or others’), not the material world.

What I’m trying to get at is how we can seemingly rise above our own consciousness to observe ourselves interpreting the world through the medium of the energy flows in which we are immersed—and which we narrowly interpret to suit ourselves. That is, I’m out to show how Michael Gazzaniga’s postulate of the left-brain interpreter provides an explanation for a great deal of human behavior that causes so much trouble in a world we can’t see very clearly for what it is.

What I’m after is ways of doing better by that world than we have done up till now. Since the world conforms to our ideas of the world, doing better by ourselves means doing better by the world, and every one of its inhabitants. We’ve had it backwards all this time. It is time to straighten the world by straightening ourselves, an approach so ancient it seems almost new to us. I think we can do it.

    Howdy Steve,

    I look at “information” in an entirely different way. To me, the universe is a process, and the matter that is changed is memory of that step in the process. In that sense, all matter is information and energy is the process.

    I realize that is an uncommon perspective and maybe you can help me come up with a better term. How do we differentiate between that level of information processing and the kind we do in our heads?

    cheers,

  2. Jim, to me, information smacks of meaning, and I am not sure how we make meaning of information and energy without imposing our neural apparatus in the way. I’m stuck with the neural apparatus I’ve got and find it hard to rise above it to see it better without distorting the view. Thanks for the feedback. I think interpretation is a good term for including ourselves in the process of making meaning. It is sort of our signature–and an admission that we leave room for error. –Steve

    ‘Tis true, and as you say, we put our own arbitrary meaning to our input, however, the universe is processing itself, matter with its own intrinsic meaning… an atom is a specific packet of meaning that doesn’t need to be encoded… except for us to talk about it.

    Anyway, thanks the thoughts.

    cheers,
    jim
