John Keats's Lamia (1819) surely deserves some kind of award for Most Famously Annoying Poetry:
...Do not all charms fly
At the mere touch of cold philosophy?
There was an awful rainbow once in heaven:
We know her woof, her texture; she is given
In the dull catalogue of common things.
Philosophy will clip an Angel's wings,
Conquer all mysteries by rule and line,
Empty the haunted air, and gnomed mine—
Unweave a rainbow...
My usual reply ends with the phrase: "If we cannot learn to take joy in the merely real, our lives will be empty indeed." I shall expand on that tomorrow.
Today I have a different point in mind. Let's just take the lines:
Empty the haunted air, and gnomed mine—
Unweave a rainbow...
Apparently "the mere touch of cold philosophy", i.e., the truth, has destroyed:
- Haunts in the air
- Gnomes in the mine
- Rainbows
Which calls to mind a rather different bit of verse:
One of these things
Is not like the others
One of these things
Doesn't belong
The air has been emptied of its haunts, and the mine de-gnomed—but the rainbow is still there!
In "Righting a Wrong Question", I wrote:
Tracing back the chain of causality, step by step, I discover that my belief that I'm wearing socks is fully explained by the fact that I'm wearing socks... On the other hand, if I see a mirage of a lake in the desert, the correct causal explanation of my vision does not involve the fact of any actual lake in the desert. In this case, my belief in the lake is not just explained, but explained away.
The rainbow was explained. The haunts in the air, and gnomes in the mine, were explained away.
I think this is the key distinction that anti-reductionists don't get about reductionism.
You can see this failure to get the distinction in the classic objection to reductionism:
If reductionism is correct, then even your belief in reductionism is just the mere result of the motion of molecules—why should I listen to anything you say?
The key word, in the above, is mere; a word which implies that accepting reductionism would explain away all the reasoning processes leading up to my acceptance of reductionism, the way that an optical illusion is explained away.
But you can explain how a cognitive process works without it being "mere"! My belief that I'm wearing socks is a mere result of my visual cortex reconstructing nerve impulses sent from my retina which received photons reflected off my socks... which is to say, according to scientific reductionism, my belief that I'm wearing socks is a mere result of the fact that I'm wearing socks.
What could be going on in the anti-reductionists' minds, such that they would put rainbows and belief-in-reductionism, in the same category as haunts and gnomes?
Several things are going on simultaneously. But for now let's focus on the basic idea introduced yesterday: The Mind Projection Fallacy between a multi-level map and a mono-level territory.
(I.e: There's no way you can model a 747 quark-by-quark, so you've got to use a multi-level map with explicit cognitive representations of wings, airflow, and so on. This doesn't mean there's a multi-level territory. The true laws of physics, to the best of our knowledge, are only over elementary particle fields.)
I think that when physicists say "There are no fundamental rainbows," the anti-reductionists hear, "There are no rainbows."
If you don't distinguish between the multi-level map and the mono-level territory, then when someone tries to explain to you that the rainbow is not a fundamental thing in physics, acceptance of this will feel like erasing rainbows from your multi-level map, which feels like erasing rainbows from the world.
When Science says "tigers are not elementary particles, they are made of quarks" the anti-reductionist hears this as the same sort of dismissal as "we looked in your garage for a dragon, but there was just empty air".
What scientists did to rainbows, and what scientists did to gnomes, seemingly felt the same to Keats...
In support of this sub-thesis, I deliberately used several phrasings, in my discussion of Keats's poem, that were Mind Projection Fallacious. If you didn't notice, this would seem to argue that such fallacies are customary enough to pass unremarked.
For example:
"The air has been emptied of its haunts, and the mine de-gnomed—but the rainbow is still there!"
Actually, Science emptied the model of air of belief in haunts, and emptied the map of the mine of representations of gnomes. Science did not actually—as Keats's poem itself would have it—take real Angel's wings, and destroy them with a cold touch of truth. In reality there never were any haunts in the air, or gnomes in the mine.
Another example:
"What scientists did to rainbows, and what scientists did to gnomes, seemingly felt the same to Keats."
Scientists didn't do anything to gnomes, only to "gnomes". The quotation is not the referent.
But if you commit the Mind Projection Fallacy—and by default, our beliefs just feel like the way the world is—then at time T=0, the mines (apparently) contain gnomes; at time T=1 a scientist dances across the scene, and at time T=2 the mines (apparently) are empty. Clearly, there used to be gnomes there, but the scientist killed them.
Bad scientist! No poems for you, gnomekiller!
Well, that's how it feels, if you get emotionally attached to the gnomes, and then a scientist says there aren't any gnomes. It takes a strong mind, a deep honesty, and a deliberate effort to say, at this point, "That which can be destroyed by the truth should be," and "The scientist hasn't taken the gnomes away, only taken my delusion away," and "I never held just title to my belief in gnomes in the first place; I have not been deprived of anything I rightfully owned," and "If there are gnomes, I desire to believe there are gnomes; if there are no gnomes, I desire to believe there are no gnomes; let me not become attached to beliefs I may not want," and all the other things that rationalists are supposed to say on such occasions.
But with the rainbow it is not even necessary to go that far. The rainbow is still there!
Why do I think I have free will?
I think I have free will because I tell my hand to type and it types.
And why do I think that that was my own free will and not somebody or something else's?
Wait, what do I even mean when I say "free will"?
I mean that I could do whatever I wanted to.
And what controls what I "want" to do? Is it me or something/one else?
Why do I think that I control my own thoughts?
My thoughts seem instantaneous, maybe I don't control my own thoughts.
I can say things without thinking about it beforehand, sometimes I agonize over a decision (It's a Saturday, should I get out of bed right now or later?) and I choose one decision without coming to a conclusion and without knowing why I chose it.
Maybe, subconsiously, I was hungry, or obeying a habit.
If I was hungry, or if some other instinct was propelling me, then I don't really have free will when it comes to simple things like this, although "I" can override my instincts, so it's my instincts serving me, as a mental shortcut, and I am not a slave to it, so I do have free will.
If it was a habit, it was I who created my habits by repetition, so I have free will. I can also override my habits. Who's to say that my overrides aren't controled by something/one?
I feel like I have free will, but maybe that's how whatever controls me "wants" me to feel.
Maybe I'm just a zombie, writing paragraphs on free will because the laws of nature are making me do it.
In that case, how am I supposed to assume that I am, in fact, correct about me having free will?
So I don't have free will at all? Is that the answer that other people have gotten to? Are there gaping holes (or even tiny holes) in my logic, and are there angles that I havn't considered yet?
I still feel like I have free will. Maybe I should have written that like, 'I still feel like I have "free will".'
This may be like the time the math teacher told me to prove that two lines were parallel and I couldn't because I didn't know about Thales' theorem.
Could someone please help me figure this out? I don't see a way to continue from, "Either I have free will, or who/whatever is controling me is making me think that I have free will." I'm not sure how those two universes would be different.
Edit: In a universe where someone is controling me, I'm guessing "he" would have a plot in mind. The universe doesn't appear to have a plot, but maybe I'm just too small to see it, or- wait, who says the universe doesn't appear to have a plot? I don't think I know enough to answer this question. Help?
Well, if that's what you mean, then you certainly don't have free will, at least not if you're anything like me. There's lots of things I've wanted to do in my life that I haven't been able to do.
So, if that's really what you mean by "free will", I submit to you that not only do you not have this thing, you don't even feel like you have this thing. Conversely, if you're talking about something you do feel like you have, then your descriptio... (read more)
