I'm not sure. Suppose an archaeologist uncovers tablets on which are inscribed a lost language. What did the archaeologist discover? Seemingly, information that can no longer be decoded. Years later, the language was translated. Did the information spring into being? Or was it always there? — hypericin
The statement 'the Sun and the stars revolve around Earth and they move from east to west' is, if taken literally (i.e. as an accurate description of 'what really happens in the external world'), false. — boundless
I think the salient point is that there can be multiple reductive explanations from different perspectives. So, to say that I went to the shop because I was thirsty is a reductive explanation, as much as saying I went to the shop because of certain neural activity is. Such different explanations do not contradict, and should not exclude, one another. — Janus
So for example, the epiphenomenalist might say consciousness does no work, just "goes along for the ride", so to speak, but that would be an illegitimate elimination of one reasonable way of explaining human behavior. I think what puzzles people is that we cannot combine the two explanations or achieve any absolute perspective which would eliminate one and retain the other. 'Either/ or' thinking seems to generally dominate the human mind.
Have you read the book? I feel like it sort of gets misrepresented in reviews because the argument really doesn't come into focus until the last chapter. Hoffman's point is an argument about a certain, fairly dominant form of naturalism that imports Kantian dualism into "science." — Count Timothy von Icarus
I agree on the type of error involved. I disagree on the track record of reductionism. How many true reductions do we have? Thermodynamics and statistical mechanics is the canonical example, but it is a rare example. 120 or so years on, the basics of molecular structure in chemistry has yet to be reduced to physics. Reductions are not common. Unifications, the explanation of diverse phenomena via an overarching general principle are far more common. For example, complexity studies explains disparate phenomena like earthquakes and heart beats via a similar underlying mathematics. But of course this does not say that heart beats or earthquakes are "nothing but," the math they share in common. Yet it seems to me that unifications are very often misunderstood as reductions. — Count Timothy von Icarus
That and facts about composition is misunderstood as a reduction. To be sure, all cells are made from molecules. All molecules are made from atoms. This isn't a reduction. You can't predict how a molecule works from theory in physics, you need all sorts of ad hoc empirically derived inputs for it to work. — Count Timothy von Icarus
But I think the error you identify is directly related to smallism and reductionism. The justification for the causal closure principle is normally that minds are "nothing but" brains/bodies, and the brains and bodies are "nothing but" atoms and their constituent particles. Particles are the smallest structure and thus most fundemental. Everything is "nothing but" these, and so everything is describable in terms of their interactions. This makes all other causal explanations duplicative. At best they are a form of data compression. And so this makes motive irrelevant and conciousness epiphenomenal. — Count Timothy von Icarus
Exactly...the reductionists seek to analyze the physical in terms of the mental (idealism) or the mental in terms of the physical (eliminative physicalism). Tendentious thinking prevails on both sides. — Janus
I think Plantinga's argument is ultimately just one simplified form of an entire web of arguments that can be made vis-á-vis psychophysical harmony, causal closure, and epistemology. Hoffman is able to flesh this out with some models and empirical results. Is it air tight? No. But then again what they are arguing against is also a position that is not airtight. Yet this position, like reductionism, is one that seems to demand that it be "assumed true until decisively proven otherwise," and I'd venture that there is not good grounds to accept this — Count Timothy von Icarus
Physicalism is normally defined in terms of casual closure. Reductionist materialism also assumes causal closure. But if causal closure is true the mental never—on pain of violating the principle—has any effect on behavior. It is just "along for the ride." Everything is determined by particles and how they interact, so no one ever goes and gets a drink "because they feel thirsty" (at least not in the causally efficacious sense of "cause.") — Count Timothy von Icarus
Alvin Plantinga's rather fun argument called the evolutionary argument against naturalism (EAAN). If it comes up with apologists a lot these days. Here's a basic overview:

The OP raised this in relation to Hoffman's theory too. — Tom Storm
Have you made it to the last chapter? He sort of turns everything he has said on his head. His point is that a common way of looking at the relationship between mind and nature is self-refuting. Plantinga has previously made a similar argument. I don't think this is a bad argument, although the way it is framed it does seem like he is refuting himself as well. But I take it that this is exactly the point, his position is self-refuting because it's situated in popular assumptions that are self-refuting. — Count Timothy von Icarus
To those who have seen Tarkovsky's Solaris: what do you make of the surprisingly long (even for Tarkovsky, I think) bit where the ex-pilot Burton is in a car going through a big city, along motorways, overpasses and tunnels?
Normally I like the slow stuff in Tarkovsky, but this seems awkward and perplexing. The sounds, which I think are meant to be futuristic, do not even seem to match the familiar urban scene.
It ends with an abrupt cut to the wildflower meadow at Kelvin's house (which looks exactly like a Russian dacha), so it looks like a juxtaposition between inhuman modernity and bucolic serenity, but it still seems odd. My guess is that in fact, Tarkovsky made do with footage that did not turn out as well as he'd imagined. — Jamal

Just watched "Patterson" with Adam Driver. A sweet, understated, lovely little movie. I can't remember when I've watched another I enjoyed more. I haven't seen Driver in anything else, but he was wonderful in this. — T Clark
I'm really glad people are interested, but I will remind you that there is an email address set up for questions and potential solutions because I sent this to a couple of forums and fifty philosophy departments, so trying to keep up with communication in every avenue is going to be difficult — Dan
I think we can make an even stronger statement: the only way that the usual probability rules (normalizability, additivity) can be satisfied on an infinite sample space is if all but a finite number of simple outcomes have probability zero. — SophistiCat
I can try to give you an example of "an algorithm that gives all integers (without limit) SOME probability of happening" if you like. — flannel jesus
This algorithm is theoretically capable of randomly producing ANY of the infinite sequence of integers, but it preferentially chooses lower numbers. — flannel jesus
I just had a train of thought I thought might be vaguely interesting:
1. With an infinite number of options, not all options can have equal probability. — flannel jesus
I have a metaphysical probability question:
Suppose there are an infinite number of parallel Earths. Alice uses a teleporter to teleport to a random Earth. Bob tries to follow Alice, but he has to guess which Earth she teleported to. What are Bob's chances of getting it right? Is there any way for a teleporter machine to randomly select an Earth out of an infinite number of them in a finite amount of time, or is there always going to be, practically speaking, only a finite amount of Earths for Alice to teleport to because of the limitations of the machine? — RogueAI
What if I cheat and say the teleporter pokes a hole into the universe and the universe somehow, through a mysterious process, randomly picks an Earth out of an infinitely large ensemble for Alice to teleport to? Are Bob's chances of teleporting to Alice's world zero? — RogueAI
In fact, this means that is some kind of hidden collusion between these candidates. — Linkey
This is explained by the fact that the 1% of richest people control the mass media and are motivated to keep this situation as long as possible. — Linkey
The middle-class female does not need any resources from a male — Tarskian
There isn't a problem with specialist terms. But "cogent and useful" is both cogent and useful as a definition of "make sense". I would rather not have to try to find another definition. "Cogent and useful" can mean different things in different contexts. — Ludwig V
In the background, I understand, there are people who have doubts about the validity of mathematical induction — Ludwig V
In the supertasks article, they mention a “hotel with a countably infinite number of rooms”. Right there, at the premise, what does “countably infinite” point to? That’s nonsense. That’s a square circle. We don’t get out of the gate. The infinite is by definition uncountable — Fire Ologist
When I first saw the phrase "countably infinite", I thought that was absurd, and I still think it is an unfortunately ambiguous description of what it means. I would put it this way - any (finite) part of the infinite set can be counted, even though the whole of the set cannot be counted in one go. — Ludwig V
This isn't the result of word games. The observations that underlie solipsism are not a matter of semantics. We observe that we do not experience anything that isn't Sensory Data. — Treatid
But if I didn’t think of the sickness of the situation and recognize all of the apparatus and planning that had to be in place to put me here, and I just played along, that doesn’t make me a hero or murderer for pulling the lever. It makes me quick at math under some pressure. It demonstrates the immorality of telling someone to make that choice in that fabricated situation. It doesn’t make me any better or worse if I made a choice that someone else would have made differently. — Fire Ologist
Yes, I hate the trolley problem. It's one of those things that gives philosophy a bad name. It's nothing like any person will ever have to face in the real world. — T Clark
I’m using Thomson’s lamp to show that continuous motion entails contradictions. — Michael
The problem is that if motion is continuous and if the sensors are set up as stated — Michael
Continuous motion suffers from the same problem. We can imagine sensors at each successive half way point that when passed turn a lamp on or off. Is the lamp on or off when we finish our run? — Michael
The simple solution is to say that motion isn’t continuous. Discrete motion at some scale is a metaphysical necessity. — Michael
Swoooooooning. — AmadeusD
Beloved Little Spot
Do you know where I like to linger
In the cool of an evening?
In the quiet valley there spins
A little mill,
And there is a little brook beside it,
With trees standing all around it.
I often sit there for hours on end,
Looking around and daydreaming.
Even the little flowers in the grass
Begin to speak,
And the little blue one says:
Look at how my little head is hanging!
The little rose with a thorny kiss
Has pricked me:
Ah, it has made me so sad
That my heart has broken.
There approaches a small white spider,
saying: Be content;
Some day you will die,
For that is the way it is here on this earth;
Better that your heart breaks
From the kiss of a rose,
Than that you never know love
And die loveless. — Friederike Robert, tr. Emily Ezust
Knowledge, then, is multifaceted. Since to agree, to accept and to devote have different truth conditions - or none at all, like a devotion. One can say one knows in different senses. Knowledge isn't one kind of thing, and an item of knowledge need not be a statement. And knowing as conviction may not be itemizable at all. — fdrake
Yes, there are different kinds of knowing. There is 'knowing how', there is the knowing of familiarity and there is 'knowing that'. I think the salient question in this thread concerns only 'knowing that' or propositional knowing, because the other two categories do not necessarily involve belief. — Janus
