What Does the Nation of China Think About Phenomenal States?

Abstract:

Critics of functionalism about the mind often rely on the intuition that col-

lectivities cannot be conscious in motivating their positions. In this paper,

we consider the merits of appealing to the intuition that there is nothing that

it’s like to be a collectivity. We demonstrate that collective mentality is not

an affront to commonsense, and we report evidence that demonstrates that

the intuition that there is nothing that it’s like to be a collectivity is, to some

extent, culturally specific rather than universally held. This being the case,

we argue that mere appeal to the intuitive implausibility of collective con-

sciousness does not offer any genuine insight into the nature of mentality in

general, nor the nature of consciousness in particular.

Shape of Broad Minds

The graphical representation of minds is difficult, thus do many designers of cognitive science and philosophy of mind book covers resort to the beaten-to-death motif of bald-dude's-head. Excessively difficult, then, is the graphical representation of alternate minds. The difficulty is sometimes overcome, however. Witness the following super cool album cover art for Shape of Broad Minds: Craft of The Lost Art.

Additional images from and info on the album are can be found at the following post at sleevage.com: Shape of Broad Minds: Craft of The Lost Art

What if a group-mind made a music video?

Palindromy and Time-Reversals

Anyone who watched a film run backwards is well aware of the phenomenal differences that temporal orderings make. However, as Egan explored magnificently in Permutation City, the time-reversal of one's own mind need not give rise to any introspectible differences.

Here's a palindromic film: playing it backwards would yield the same film experience.



Though not palindromic, I can't help but be reminded of the "Patience" episode of Wonder Showzen. (Warning, if you've never seen Wonder Showzen before, "Patience" may not be the best introduction.)

Accelerando

I just finished reading Accelerando by Charles Stross today. My two word mini review is: Wow, damn. Slightly longer: I'd have to rank this up there with Sterling's Schismatrix, Stephenson's Snow Crash, Vinge's A Fire Upon the Deep, and Egan's Diaspora as far mind-bending idea-saturation goes. This is a depiction of a post-singularity/post-human future thoroughly informed by contemporary experience with internet and related technologies. Stross also demonstrates quite a bit of familiarity with philosophy of mind, especially Dennett's (the Dennettian notions of zimboes and Cartesian theaters get put to work). (There's quite a bit of Clark/Chalmers extended mind stuff, too.)

It will take me a while to fully digest all of Stross's ideas relevant to the Alternate Minds project, (e.g. his treatment of group minds and virtual minds) but I'm especially impressed right now with his depiction of transcendent intelligences and the threat they pose to the enhanced-but-still-human post-humans (and the development of what Stross calls "cognitive anti-bodies" and what I call "anti-minds").

Memory and quantum cognition

"Scientists Model Words as Entangled Quantum States in our Minds" @physorg:

Research has shown that words are stored in our memories not as isolated entities but as part of a network of related words. This explains why seeing or hearing a word activates words related to it through prior experiences. In trying to understand these connections, scientists visualize a map of links among words called the mental lexicon that shows how words in a vocabulary are interconnected through other words.

However, it’s not clear just how this word association network works. For instance, does word association spread like a wave through a fixed network, weakening with conceptual distance, as suggested by the “Spreading Activation” model? Or does a word activate every other associated word simultaneously, as suggested in a model called “Spooky Activation at a Distance”?

Although these two explanations appear to be mutually exclusive, a recent study reveals a connection between the explanations by making one novel assumption: that words can become entangled in the human mental lexicon. In the study, researchers from the Queensland University of Technology (QUT) in Australia and the University of South Florida in the US have investigated the quantum nature of word associations and presented a simplified quantum model of a mental lexicon.

Neuromancer turns 25

"Neuromancer turns 25: What it got right, what it got wrong" @macworld:

Neuromancer tells of famous hacker, McCoy Pauley, who originally taught Case how to hack and later died of heart failure during an especially dangerous assault in cyberspace. But before Pauley died (in the clinical sense), some people hooked his brain up to a computer and dumped the contents--his hacking expertise, memories, habits, idiosyncrasies, everything--out onto a ROM cassette, creating a "construct" of the former hacker. Long after the flesh-and-bone Pauley's death, Case and Molly steal the construct, which can think and talk, so that Pauley can help them complete their mission.

The conversations between Case and "the flatline" as he calls the construct, are priceless. The construct isn't quite sure whether he's alive or dead, and when he learns that he is just data on a disk he isn't very happy about the situation. Pauley eventually asks Case to erase the ROM, effectively putting his mind to rest for good.

The "ZALGO!" meme, explained and complied at the following links:

Some examples:

Natural Born Solipsists

In the Greg Egan novels, Permutation City and Diaspora, Egan uses the term "solipsists" to refer to simulated beings that inhabit exclusively virtual worlds, abandoning all interaction with the external physical world.

(In philosophy, solipsists do not believe anything external to their minds exist. In Egan-ese, the solipsists may very well believe in an external world. They just don't care much about it.)

The solipsists are typically software descendants of natural human minds. But in the "Wang Carpets" section of Diaspora, and the short story upon which it is based, Egan suggests the possibility of naturally occurring solipsists. In the story, enormous polysaccharide biocomputers (implementing Wang tiles) support the 16-dimensional virtual universe housing intelligent hyper-squids.

For a relatively concise description of Egan's "Wang's Carpets" see the opening sections of the Biocomputation chapter of Biomedia by Eugene Thacker. [Link to Google Books.]

Egan's story invites the question of whether such naturally occurring virtual minds are indeed possible. Besides just blind random luck, how would the requisite hardware substrate come into being? there may be a tendency to think of the virtual affairs thereby simulated as epiphenomenal, and thus inconsequential to any of the selection pressures that may otherwise result in the evolutionary emergence of the hardware substrate. But perhaps this assumption of the virtual as epiphenomenal is mistaken.

Group Mind Definition

From Key Terms in Philosophy of Mind (in press):

group mind, a hypothetical mind, AKA a “hive mind,” that depends on members of a group such that it is not the mind of any one of the members of the group. The individual members of the group may either be individually mindless or individually in possession of minds distinct from the group mind.

New Progress Toward Quantum Computer

From NatureNews: "Spooky computers closer to reality: Solid-state quantum processing demonstrated."

The system processed two algorithms written specially for quantum systems.

The first is Grover's search algorithm, also known as the reverse phone book search, where someone's number is known but not the name. The processor essentially reads all the numbers in the phone book at once to find the single correct answer. "At the end the qubit will be in one state, not superposed, and that's the answer," says DiCarlo.

The second, more simple, algorithm, the Deutsch-Jozsa algorithm, tests whether the flip of a coin is fair or not.

DiCarlo's processor got the reverse phone book search right an impressive 80% of the time and the coin-flip algorithm right about 90% of the time.

[...]

But this technique could not read out the answer in a system with many more qubits, says quantum-computing expert Hans Mooij from the Delft University of Technology in the Netherlands. The development of the processor is good news Mooij adds. "This is a necessary step," he says. "If this can be done, the next thing can be done."

DiCarlo is cautious. "We've made a very simple quantum processor," he says. "It's by no means a quantum computer."

He is working to give the processor more qubits, and so more processing power. He thinks that scaling up to three or four quibits will be relatively straightforward, but beyond that the problem becomes a lot harder, and the coherence time needed will be very difficult to attain. Mooij agrees: "From three or four to ten they will need to make a big step again."

Of Anti-minds and the Swarm

The world is everything that is the case



Originally uploaded by Pete Mandik.

Does it take a mind to detect a mind? If there could be a principled answer to this question the implications would be huge for the philosophy and science of mind.

Consider that so much of science depends on the unintelligent detection of unintelligents. Hydrogen samples are not particularly intelligent. Further, mechanisms capable of detecting the presence of hydrogen need not themselves be intelligent.

Maybe part of being a natural kind is that the unintelligent detection of instances of that kind is possible. Jerry Fodor has suggested that non-natural kinds like crumpled shirts or doorknobs can only be detected by minds. You have to be the sort of thing that knows a bunch of stuff in order to "light up" in the presence of a door knob.

In the Sterling short story "Swarm" (excerpts here), the Nest is this asteroid that is mostly just a big super-organism that wanders the universe and whenever it is "invaded" it assimilates the invaders. Most of the various diverse species in the asteroid were once representatives of vast space-faring technological cultures that, when they encountered the Nest, got taken over and reduced to unintelligent animals and integrated into the Nest ecology inside of the asteroid. Swarm is an intelligent organism activated under certain instances for the protection of the Nest. Swarm explains how ultimately useless intelligence and consciousness is and suggests that the Nest is entirely unintelligent, and that the Nest grows a new Swarm whenever an intelligent invader needs to be dealt with. Once the intelligent invader is dealt with (rendered into a dumb slave animal) then Swarm self-destructs being no longer needed.

It occured to me that Swarm was to minds what antibodies are to germs, so I coined "anti-mind". It also occurred to me that if Swarm was right that prior to the activation of Swarm, the Nest group organism was truly non-cognitive, then whatever mechanism that activates the growth of a new Swarm must itself be an unintelligent mechanism. So, the idea of an anti-mind is the idea of a thing that is not a mind but is capable of detecting minds. But this leads to what strikes me as some pretty interesting philosophical questions: Is there any way a dumb mechanism can detect the presence of intelligence? Can an unconscious mechanism detect the presence of consciousness?

If Dennett is right, intentional systems are detectable only from the intentional stance, which I take to entail that only minds can detect minds. If a lot of qualia-freaks are right, the only way to detect the presence of qualia is to have some yourself, and thus only consciousness can detect consciousness.

If these remarks are correct, the implications for science fiction are obvious: the "anti-mind" in the Sterling story is impossible. But enough about fiction: what about science? If the impossibility of unintelligent detection entails that the kinds that are intelligently detected are non-natural, then is a full-blown science of such kinds thereby doomed?

Excerpts from Bruce Sterling's Swarm

"You are a young race and lay great stock by your own cleverness, " Swarm said. "As usual, you fail to see that intelligence is not a survival trait."

Afriel wiped sweat from his face. "We've done well," he said. "We came to you, and peacefully. You didn't come to us."

"I refer to exactly that," Swarm said urbanely. "This urge to expand, to explore, to develop, is just what will make you extinct. You naively suppose that you can continue to feed your curiosity indefinitely. It is an old story, pursued by countless races before you. Within a thousand years perhaps a little longer your species will vanish."

"Intelligence is very much a two-edged sword, Captain-Doctor. It is useful only up to a point. It interferes with the business of living. Life, and intelligence, do not mix very well. They are not at all closely related, as you childishly assume."

"But you, then you are a rational being”"

"I am a tool, as I said." "When you began your pheromonal experiments, the chemical imbalance became apparent to the Queen. It triggered certain genetic patterns within her body, and I was reborn. Chemical sabotage is a problem that can best be dealt with by intelligence. I am a brain replete, you see, specially designed to be far more intelligent than any young race. Within three days I was fully self-conscious. Within five days I had deciphered these markings on my body. They are the genetically encoded history of my race within five days and two hours I recognized the problem at hand and knew what to do. I am now doing it. I am six days old."

"Technology, though I am capable of it, is painful to me. I am a genetic artifact; there are fail-safes within me that prevent me from taking over the Nest for my own uses. That would mean falling into the same trap of progress as other intelligent races."

Mr. Freeze, the Iced-Time Demon

Fear of a Blue Planet


Originally uploaded by Pete Mandik

1. Meet Mr. Freeze

Mr. Freeze is an iced-time demon. Mr. Freeze exists outside of my subjective time. He has the power to change the amount of objective time it takes for subjective time to pass. Among other things, Mr. Freeze can freeze my subjective time without my noticing. Mr. Freeze might freeze subjective time by not just freezing me, but also anything in my perceptual environment (clocks, etc.). Thawed time occurs when subjective time is in perfect step with objective time. Iced time comes in two flavors. The first occurs when subjective time is frozen relative to objective time. The second occurs when objective time is frozen relative to subjective time.



2. Iced Time: Flavor the First

Between any two subjective instants (subjective temporal units of zero duration) Sn and Sn+m, Mr. Freeze can insert a non-zero amount of objective time without my noticing. And he can insert two non-zero duration units of objective time without my noticing. And he can insert three. Leaping inductively, it follows that Mr. Freeze can insert an infinite amount of objective time between any two subjective units without my noticing. Suppose that it is now subjectively noon. How much objective time will pass before subjective noon+m? An infinite amount. Will I notice that noon+m objectively effectively never arrives? No, I will not. How much objective time needs to pass for me to have a subjective experience as of time passing? None at all. Effectively, no objective time needs to pass at all for me to have a subjective experience as of the passage of time.



3. Iced Time: Flavor the Second

Just as Mr. Freeze can insert units of objective time between my subjective units, he can remove them. Between any two subjective instants (subjective temporal units of zero duration) Sn and Sn+m, Mr. Freeze can remove a non-zero amount of objective time without my noticing. And he can remove two non-zero duration units of objective time without my noticing. And he can remove three…[insert inductive leap here]. Mr. Freeze can remove an infinite amount of objective time between any two subjective units without my noticing. Now it’s objective time that has been frozen and my own life can pass, in its entirety, in (objectively) no time at all.



4. Objective Time: Who Needs It?

If certain assumptions of multiple realizability and the computational theory of mind are true, then my entire mental life can be structurally isomorphic to a computer program which, when run, will have phenomenal consciousness just as I do. And if the stuff about Mr. Freeze and iced time in 1, 2, and 3 are true, then whatever structures are realized by objective temporal relations can be realized by non-temporal relations. Thus, the program doesn’t even need to be run. Just sitting, inert, written on a (very large) disc, the static un-run program suffices for the instantiation of the entirety of my time consciousness.

Finite Will and Infinite Will

Gualtiero Piccinini @ Brains calls attention to this NYT article on finite will: "Tighten Your Belt, Strengthen Your Mind". Excerpt:

No one knows why willpower can grow with practice but it must reflect some biological change in the brain. Perhaps neurons in the frontal cortex, which is responsible for planning behavior, or in the anterior cingulate cortex, which is associated with cognitive control, use blood sugar more efficiently after repeated challenges. Or maybe one of the chemical messengers that neurons use to communicate with one another is produced in larger quantities after it has been used up repeatedly, thereby improving the brain’s willpower capacity.

Here's a little bit of fiction I wrote a few years ago about infinite will: "Desire Magnitudes". Excerpt:

I tear open my package, and, as is typical for ET merchandise, the accompanying literature is indecipherable trash. Fuck it. I pop a pill and wash it down with some hot sludge. I'm not real sure what to expect, but I'm figuring on an ingestible analogue to my previous surgery. I'm figuring nanobots are going to modify my frontal lobes allowing for the simulation of an indefinite number of ersatz consciousnesses to deal with an indefinite number of annoying distractions. Wrong answer, dude. That is not what this pill does to me at all. Just a few seconds after swallowing, the pill establishes various interfaces with my brain, and I know my way around my cerebrum well enough to know what's what. The first interface established between the nanoprocessors and my brain is through the visual areas of occipital cortex. A translucent blue rectangle pops into my field of view. White alphanumerics scroll from top to bottom. It's extraterrestrial at first, but as the pill coordinates the visual processing with the semantic association networks in my left temporal cortex, the text writhes into recognizable English:

WHAT DO YOU DESIRE?

Plasticity and the Perception of Higher Dimensions

Sacks and Siegel in Nature report on the recovery of steroscopic vision in a patient suffering from stereo blindness for 50 years. If cortex is indeed that plastic, I can't help but ask, "why stop with only 3-dimensions?" Besides being cool, there might even be practical applications in training individuals to be able to see objects in spaces of four dimensions and higher. Data about a complex dynamical system might be handled more easily if its multidimensional state-space can be directly grasped by the human visual system. Things might "pop-out" of a data set that might otherwise be difficult to detect.

Questions arise as to how to train someone to pull this off. What does it even mean for vision to take place in higher dimensions? It might be useful to think about the geometry of photography for a bit here. The photography of a three-dimensional object involves a projection onto a two-dimensional surface. Stereoscopy is accomplished by integrating projections from a single 3-D object onto two different 2-D surfaces. By analogy, photography in the fourth dimension would involve the projection of a hypersolid onto points in a 3-D volume. 4-D steroscopy ("Hyperscopy"?) would then involve, I guess, the integration of projections of a single 4-D object onto points in different 3-D volumes.

One might question whether a person, being only 3-D, could possibly accompish hyperscopy, given that our irritable surfaces--our retina, etc.--are essentially only 2-D. The key to realize is that the dimensionality of our sensor arrays is potentially surmountable. The points in, e.g. our retina, can be mapped onto points in a volume--this is precisely what enables plain-old steroscopy in the first place. And our brains are capable of representing higher-dimensional state-spaces: gustory state-space is at least four-dimensional and olfactory state-space is six-.

Here then, in theory, is how to train someone to be hyperscopic. First, off, the 4-D objects are going to have to be computer generated. Second, computer simulated 3-D retina--3-D arrays of voxels--will be projected onto by the 4-D objects. Third, information from each of these voxels will be projected--via video goggles--to a dedicated portion of the person's visual field. That is, the visual field will be partitioned into the same number of subregions as there are voxels in the 3-D computer-simulated retina. Fourth, equip the person with some means of rotating the 4-D objects (since having control over inputs seems to be important in perceptual plasticity). Fifth, train the person to perform 4-D object recognition tasks. Objects in the training set should include objects that can only be distinguished by their 4-D charactersitics.

If such a training regime could be successful executed, would it be 4-D vision? Would the hyperscopist have 4-D qualia?

Alternate Minds Project Overview

The aim of the Alternate Minds Project is to explore science fictional permutations of the concept of mind (and related concepts such as intelligence, perception, selfhood). By entertaining speculative scenarios wherein the target concepts are bent almost beyond recognition, we gain insights into the nature of mind and catch glimpses of new possibilities. Initial investigations will be clustered around seven key themes.

1. Virtual Minds are typically thought of as embedded in simulated environments and the minds themselves may be artificial. One intriguing question is whether there can be naturally occurring instances of virtual minds, or whether there must always be an artificial component that defines their virtuality.

2. Infinite Minds are minds infinite in one or more capacities, such as infinite intelligence, infinite perceptual acuity, or infinite will power. Of our various mental capacities that come in degrees, for which, if any, does it make sense to imagine versions that are infinite? Can we coherently conceive of, for example, a being with infinite will-power?

3. Group Minds are minds with proper parts that are themselves minds. Are any of our minds already proper parts of group minds? If there were group minds in our midst, how would we know?

4. Time-traveling Minds either literally move through time in non-standard ways or employ high degrees of computational power to simulate target events. What cognitive/computational advantages are there to intelligent systems that harness literal time-travel? From a computational point of view, what are the relative resource costs of literal versus simulated time-travel?

5. Hyper-spatial Minds: One of the most fun things to think about in contemplating minds inhabiting spaces of dimension n>3 are questions concerning the perceptual phenomenology of seeing (feeling, etc.) hyperspatial objects. What is it like to have four- (or five- or six-) dimensional eyes? In addition to these questions concerning hyperspatial sensory input, are interesting questions of output. What is it like to move a body though a hyperspatial manifold? Last, but not least, are questions concerning the computational processes mediating between inputs and outputs. What advantages and obstacles are presented to circuit-engineering a cognitive architecture where there are extra dimensions in which to wire things up.

6. Quantum Minds: The dominant approaches in contemporary cognitive science deal with minds within a classical physical framework. But what would consciousness and cognition be like if non-classical quantum principles played major roles in implementation. What would it be like to be an AI implemented on a quantum computer? What would it be like to be small enough or perceptually sensitive enough to directly perceive events occurring on quantum scales?

7. Anti-Minds are non-sapient, non-sentient systems with the capability to detect and destroy minds. They are either the ultimate evil or the ultimate protection against the dangerous effects of technologically advanced civilizations. One of the core questions raised in contemplating anti-minds is whether there can exist non-intelligent mechanisms for the detection of intelligence. Such mechanisms could be crucial in the search for extra-terrestrial intelligence.
