I Am a Strange Loop (69 page)

The inverted-spectrists say it is pure
feeling.
Since this distinction is completely independent of physics, it amounts to dualism (something we already knew, in effect, since belief in Cartesian Egos is a kind of dualism).

Violets Are Red, Roses Are Blue

Why is it that those who postulate the inverted spectrum always do so only for experiences that lie along a one-dimensional numerical scale? It seems like a great paucity of imagination to limit oneself to swapping red and blue. If you think it’s coherent to say to someone else, “Maybe
your
private inner experience of red is the same as
my
private inner experience of blue”, then why would it not be just as coherent to say, “Maybe
your
private inner experience of looking at a red rose is the same as
my
private inner experience of looking at a blue violet”?

What is sacrosanct about the idea of shuffling colors inside a spectrum? Why not shuffle all sorts of experiences arbitrarily? Maybe
your
private inner experience of redness is the same as
my
private inner experience of hearing very low notes on a piano. Or maybe
your
private inner experience of going to a baseball game is the same as
my
private inner experience of going to a football game. Then again, maybe your private inner experience of going to a baseball game is the same as my private inner experience of going on a roller-coaster ride. Or maybe it’s the same as my private inner experience of wrapping Christmas presents.

I hope that these sound ridiculously incoherent to you, and that you can move step by step backwards from these variations on the inverted-spectrum theme to the original inverted-spectrum riddle without losing the sense of ridiculousness. That would be most gratifying to me, because I see no fundamental difference between the original riddle and the patently silly caricatures of it just offered.

A Scarlet Sardine

The inverted-spectrum riddle depends on the idea that we are all born with a range of certain “pure experiences” that have no physical basis but that can get attached, as we grow, to certain external stimuli, and thus specific experiences and specific stimuli get married and from then on they are intimately tied together for a lifetime. But these “pure experiences” are supposedly not physical states of the brain. They are, rather, subjective
feelings
that one simply “has”, without there being any physical explanation for them. Your brain state and mine could look as identical as anyone could ever imagine (using ultra-fine-grained brain-scanning devices), but whereas I would be feeling blueness, you would be feeling redness.

The inverted-spectrum fairy tale is a feeble mixture of bravado and timidity. While it boldly denies the physical world’s relevance to what we feel inside, it meekly limits itself to a one-dimensional spectrum, and to the electromagnetic one, to boot. The sonic spectrum is too tied to objective physical events like shaking and vibrating for us to imagine it as being inverted, and if one tries to carry the idea beyond the realm of one-dimensional spectra, it becomes far too absurd to give any credence to.

Yes, People Want Things

There’s something else in the philosophical literature on consciousness that gives me the willies, and that is the so-called “problem of free will”. Let me describe this second sacred cow, and then try to dispatch it, too, as quickly as possible. (It, too, suffers from sacred mad cow disease.)

When people decide to do something, they often say, “I did it of my own free will.” I think what they mean by this is usually, in essence, “I did it because I wanted to, not because someone else forced me to do it.” Although I am uncomfortable with the phrase “I did it of my own free will”, the paraphrase I’ve suggested sounds completely unobjectionable to me. We do indeed have wants, and our wants do indeed cause us to do things (at least to the extent that 641’s primeness can cause a domino in a domino chain to fall).

The Hedge Maze of Life

Sometimes our desires bang up against obstacles. Somebody else drank that last soft drink in the refrigerator; the formerly all-night grocery store now closes at midnight; my friend’s car has a flat tire; the dog ate my homework; the plane just pulled out of the gate thirty seconds ago; the flight has been canceled because of a snowstorm in Saskatoon; we’re having computer troubles and we can’t seem to make PowerPoint work in here; I left my wallet in my other pair of pants; you misread the final deadline; the reviewer was someone who hates us; she didn’t hear about the job until too late; the runner in the next lane is faster than I am; and so on and so forth.

In such cases our will alone, though it pushes us, does not get us what we want. It pushes us in a certain direction, but we are maneuvering inside a hedge maze whose available paths were dictated by the rest of the world, not by our wants. And so we move willy-nilly, but not freewilly-nilly, inside the maze. A combination of pressures, some internal and some external, collectively dictates our pathway in this crazy hedge maze called “life”.

There’s nothing too puzzling about this. And I repeat, there is nothing puzzling about the idea that some of the pressures are our
wants.
What makes no sense is to maintain, over and above that, that our wants are somehow “free” or that our decisions are somehow “free”. They are the outcomes of physical events inside our heads! How is that free?

There’s No Such Thing as a Free Will

When a male dog gets a whiff of a female dog in heat, it has certain extremely intense desires, which it will try extremely hard to satisfy. We see the intensity only too clearly, and when the desire is thwarted (for instance, by a fence or a leash), it pains us to identify with that poor animal, trapped by its innate drives, pushed by an abstract force that it doesn’t in the least understand. This poignant sight clearly exemplifies
will,
but is it
free
will?

How do we humans have anything that transcends that dog-like kind of yearning? We have intense yearnings, too — some of them in the sexual arena, some in more exalted arenas of life — and when our yearnings are satisfied, we attain some kind of happy state, but when they are thwarted, we are forlorn, like that dog on a tight leash.

What, then, is all the fuss about “free will” about? Why do so many people insist on the grandiose adjective, often even finding in it humanity’s crowning glory? What does it gain us, or rather, what
would
it gain us, if the word “free” were accurate? I honestly do not know. I don’t see any room in this complex world for my will to be “free”.

I am pleased to have a will, or at least I’m pleased to have one when it is not too terribly frustrated by the hedge maze I am constrained by, but I don’t know what it would feel like if my will were
free.
What on earth would that mean? That I didn’t follow my will sometimes? Well, why would I do that? In order to frustrate myself? I guess that if I wanted to frustrate myself, I might make such a choice — but then it would be because I
wanted
to frustrate myself, and because my meta-level desire was stronger than my plain-old desire. Thus I might choose not to take a second helping of noodles even though I — or rather, part of me — would still like some, because there’s
another
part of me that wants me not to gain weight, and the weight-watching part happens (this evening) to have more votes than the gluttonous part does. If it didn’t, then it would lose and my inner glutton would win, and that would be fine — but in either case, my non-free will would win out and I’d follow the dominant desire in my brain.

Yes, certainly, I’ll make a decision, and I’ll do so by conducting a kind of inner vote. The count of votes will yield a result, and by George, one side will come out the winner. But where’s any “freeness” in all this?

Speaking of George, the analogy to our electoral process is such a blatant elephant in the room that I should spell it out. It’s not as if, in a brain, there is some kind of “neural suffrage” (“one neuron, one vote”); however, on a higher level of organization, there is some kind of “desirelevel suffrage” in the brain. Since our understanding of brains is not at the state where I can pinpoint this suffrage physically, I’ll just say that it’s essentially “one desire,
n
votes”, where
n
is some weight associated with the given desire. Not all values of
n
are identical, which is to say, not all desires are born equal; the brain is not an egalitarian society!

In sum, our decisions are made by an analogue to a voting process in a democracy. Our various desires chime in, taking into account the many external factors that act as constraints, or more metaphorically, that play the role of hedges in the vast maze of life in which we are trapped. Much of life is incredibly random, and we have no control over it. We can will away all we want, but much of the time our will is frustrated.

Our will, quite the opposite of being free, is steady and stable, like an inner gyroscope, and it is the stability and constancy of our non-free will that makes me me and you you, and that also keeps me me and you you. Free Willie is just another blue humpback.

CHAPTER 24

On Magnanimity and Friendship

Are There Small and Large Souls?

H
ERE and there in this book, alluding to James Huneker’s droll warning to “small-souled men” quoted in Chapter 1, I have somewhat light-heartedly referred to the number of “hunekers” comprising various human souls, but I have never been specific about the kinds of traits a highhuneker or low-huneker soul would tend to exhibit. Indeed, any hint at such a distinction risks becoming inflammatory, because in our culture there is a dogma that states, roughly, that all human lives are worth exactly the same amount.

And yet we violate that dogma routinely. The most obvious case is that of a declared war, where as a society we officially slip into an alternate collective mode in which the value of the lives of a huge subset of humanity is suddenly reduced to zero. I needn’t spell this out because it is so blatant. Another clear violation of our dogma is capital punishment, where society collectively chooses to terminate a human life. Basically, society has judged that a certain soul merits no respect at all. Short of capital punishment, there is incarceration, where society treats people with many different levels of dignity or lack thereof, implicitly showing different levels of respect for different-sized souls. Consider also the phenomenal differences in the measures taken by physicians in attempting to save lives. A head of state (or the head of any large corporation) who has a heart attack will receive far better care than a random citizen, not to mention an illegal alien.

Why do I see such unequal treatments by society as tacit distinctions between the values of
souls
? Because I think that wittingly or unwittingly, we all equate the size of a living being’s soul with the “objective” value of that being’s life, which is to say, the degree of respect that we outsiders pay to that being’s interiority. And we certainly do not place equal values on all beings’ lives! We don’t hesitate for a moment to draw a huge distinction between the values of a human life and an animal life, and between the values of the lives of different “levels” of animals.
