Being a thermostat is fucking exhausting. My wife and I are the equivalent of a thermostat for our type 1 diabetic son's blood sugar. It's in our face 24/7.
- frxhvcdtgf 2y ago
  My son has a dozen or so food allergies. It is exhausting. Then, I know people with autistic kids. Wow.

    “Health is a crown that the healthy wear, but only the sick can see.” This applies to so many things, not just health. You only appreciate it when it happens to you, or you get a snapshot of someone else’s life and it humbles you.
- Trasmatta 2y ago
  I'm type 1 myself, so I feel for you. People don't realize that the hardest part is NOT needles or anything like that, it's the constant mental overhead of thinking about and managing your blood sugar every moment of every day. Every decision you make is informed by it. You make literally hundreds of micro and macro decisions related to your diabetes every day. A CGM and insulin pump have made my life easier. How old is your son?
  - GiorgioG 2y ago
    He is 13 and he wears a Tandem X2 w/Dexcom G6 (soon to be G7?). It certainly makes life easier, but like you said there's constant mental overhead. We have SugarPixels all over the house, etc. His pump beeps at him so often he's just become accustomed to it and ignores it until he starts feeling bad (typically when he's going low). But that also means that it limits his ability to do things, he's got only a handful of friends that we trust leaving him alone at their home because their parents are willing to keep checking on him, etc.
    - Trasmatta 2y ago
      Being a caregiver for a kid with t1 is exhausting, so kudos to you and your wife. The mental burden is SO HIGH for both the person with the condition and their caregivers. At some point if it feels right, it might be worth having him see a therapist or a counselor who specializes in chronic diseases. There's a very high correlation between depression and type 1 diabetes (last I read, you're like 300% more likely to experience severe depression as a T1D.) Especially once he goes into his teenage years, that's a really hard time for a lot of us diabetics (and sometimes during the "rebellious" phase, a kid will intentionally stop taking care of their diabetes). > His pump beeps at him so often he's just become accustomed to it and ignores it This is a real problem with insulin pumps and CGMs, because alarm fatigue is a real thing. It makes me mad that they insist on putting in all these alarms you can't configure, because eventually you just start ignoring it. For my CGM, I use xDrip which gives me much more customization around my alarms: I just leave on the ones that are important to me.

  Closed loop. Seriously, my t1d-related mental exhaustion is 90% reduced now that I'm using a closed loop. 95% if you don't count the "why did androidaps disconnect from my pump and which bit do I need to restart to get it working again" headaches. In a way it's eliminating too much mental effort; while it's useful as a backup, the fact I sometimes completely forget to take insulin with meals is not ideal, even if the closed loop notices and takes care of it for me (since there's inherently more lag when relying on the loop than if I dialed in the insulin at meal time).
  - Trasmatta 2y ago
    Do you still enter carbs, or do you just announce meals? I know some people with closed loops just do the latter. If you don't mind sharing, what's your time in range? I have the Omnipod 5 which is decent, but it's "closed loop" abilities are extremely conservative and a bit disappointing. I've considered going the full way with androidaps, but haven't taken the leap yet.
    - cperciva 2y ago
      Androidaps says I'm 85% within 3.9-10.0 (70-180) in the past week. I enter carbs but only to a resolution of 10g; and as I mentioned earlier I sometimes forget to enter them entirely. Are you using a Dexcom with your omnipod? My impression is that the quality of sensor is the most important factor; with a flaky sensor looping algorithms will be more conservative since they (reasonably) prioritize avoiding lows.

Which I suppose makes sense, but I have read that some people have had a lot more success with looping in Androidaps vs the Omnipod 5's algo. I also wish you could set the "target" a bit lower in the 5. You can't tell it to target below 120: I feel like 100 or 110 would be more reasonable, but again, it makes sense that they prefer being conservative.

Mind you, not from the perspective of a human ("A rock will probably experience time very quickly, because it erodes, etc. etc"), but from the perspective of the rock itself. That is, it has no senses, no memory, no capabilities for abstraction, no consciousness. This ruminating has led me to believe that time and logic are human concepts, and are not as universal as is commonly believed. With recent insights into neural networks, I wouldn't even be surprised if the laws of physics follow from the way our brains are wired, instead of the other way around. Perhaps this is simply a modern take on idealism or realism, but I can't find a strand of philosophy with which I feel at home. Obviously, there is a bootstrapping problem with trying to reason from something that cannot reason. And I am well aware that my brain must exist in some form of reality. To conclusively prove some apparatus for that is way out of the scope of science. Scientifically there is probably very little to learn from this anyway, apart from opening one's mind to some alternative possibilities. It's a fun exercise, though. However, the entire discussion about what consciousness is, strikes me as less interesting. Is this really more than being able to conjure up memories of past experiences?

  I can recommend Being No One, by Thomas Metzinger, for essays. For sci-fi, have a look at Blindsight, by Peter Watts (for free on his website: Https://www.rifters.com/real/Blindsight.html)
  - smokel 2y ago
    Thanks for the recommendations! I have read Thomas Metzinger's Ego Tunnel (2009), but as far as I understand it, he takes on a naturalist standpoint, and assumes that consciousness arises from that. I prefer to take a radical agnostic point of view, where consciousness does not even have meaning outside of those who experience it. Implying that "meaning" or "reasoning" make no sense universally.

  I find this interesting, and I think dates should always be included. But I have this question- why am I interested in the date? What changes in this message when I know the date? I feel like knowing the date sets up a conflict between "this is out of date" vs. "this is before the era of mass garbage generation" (more generously described as "with time only the classics survive)
  - mannykannot 2y ago
    There has been much debate since this was written, but not much movement towards a consensus.
  - cubefox 2y ago
    Chalmers also may have changed his view in the past 28 years.
    - robwwilliams 2y ago
      I wish. This kind of showboating in 1996 is what allowed him to achieve his professional goal—-to be the modern voice of archaic Cartesian dualism. There actual is no hard problem. Ask neuroscientist “What is the hard problem” and you will get blank stares. They just do not know, or like me, do not care. It is a muddy residue of Cartesian dualism. Boring.
      - cubefox 2y ago
        That's not convincing to me. If you say some problem "doesn't exist", I need an argument which makes a compelling case for that, which presents some kind of dissolution.

Title reminds me of Tim Hunkin's BBC series "The Secret Life of Machines", which he's put on YouTube. There is, funnily enough, an episode on central heating systems: https://www.youtube.com/watch?v=PnQ9zkBzbYc https://www.youtube.com/watch?v=PnQ9zkBzbYc EDIT: there is of course a bit about thermostats: https://www.youtube.com/watch?v=PnQ9zkBzbYc&t=1137 https://www.youtube.com/watch?v=PnQ9zkBzbYc&t=1137

johann8384 2y ago
Wouldn't the thermostat be more closely aligned with a nerve in the overall system and the control board be more aligned as the brain? The brain can get signals from multiple thermostatats in a system to control the temperature.
upghost 2y ago
Does anyone know of a smart thermostat that actually has this function? Every thermostat I've looked for has "heat mode" where it decides if it should be blasting heat or not, and "cool mode", where it decides it should be blasting the AC or not. I have not found the mythical smart thermostat that does the job of "keep the temperature around here" +/- a few degrees. I live in an area where its cold at night and hot during the day and I am bad at remembering to change the thermostat from mode to mode and haven't found a programmable IOT thermostat I can write a script for, recommendations welcome!
- ajoberstar 2y ago
  Nest thermostats have a heat and cool mode where you have setpoints for each. On older ones there was a limit on how close the two could be set.
- ewhanley 2y ago
  Ecobee thermostats can run in dual heat/cool mode
- toast0 2y ago
  Echoing the other responses, Nest and Ecobee both have this feature, and I think it may have been on the Sensi as well, but I only had a furnace then. Some basic thermostats can do this too.
- rcxdude 2y ago
  It tends to be tricky to do this without wasting a lot of power, most thermostat auto modes have a pretty wide spread of maximum and minimum temperature because otherwise you run the risk of oscillating between using energy to heat and using energy to remove the heat you've just added. It can be done care and tuning, but the average home HVAC setup is not designed or installed with care.
tananan 2y ago
This kind of panpsychistic talk to me ends up feeling more closer to a reductive materialism than what I would firstly associate Chalmers with ("hey, did you forget you can experience stuff?"), which is probably just my ignorance with his work. Because yes, you acknowledge "experience", but you make it a function of a physical state described in such and such a way. In the same way that a set of particles at points A, B, C, .. correspond to such and such a (e.g. electric) field strength at point Z, we now imagine it could correspond also to such and such an experience. It's just barely "experience" on its own terms. and elicits a kind of epiphenomenalism and powerlesness. The thermostat*, after all, doesn't choose anything nor does it profess to have any agency. So agency ought to end up some kind of ephiphenomenal "observable" of a system. But besides being deflationary in this distasteful way, what bothers me with pictures like this is that they make use of entirely subject-made divisions between objects and their environments, and presume that they might correspond to experiences because - why not? Why not thing of the bottom and upper half of thermostat as corresponding to two fields of experience? Or the quarters, sixtheents, and so on until we get to individual atoms. The thermostat doesn't "care" if I think of it as the wax and glass separately, or as a single object containing both. But we do have a unified field of experience, and it doesn't matter how another person "cuts us up" in their mind, whether it is as atoms interacting, organs behaving in unison, or just as a "body". It seems silly to say that between me and Bob having our separate experiences, there is an experience corresponding to "me and Bob", supposedly free-floating somewhere just by virtue of the two of us being cognizable as a physical system. It turns "experience" and that infamous "qualia" from something that's the most direct and obvious to a weird phantom as the output of a presumed equation which maps some description of a physical state to an "experience". No wonder you'll find people who'll retort that they don't experience things or that their consciousness is illusory - they have these weird detached notions of experiences to fight against. * I imagined a thermometer throughout reading this piece, hence the mention of wax and such. It doesn't really change the point so I'm leaving it.
- nuancebydefault 2y ago
  Each time someone tries to explain in a scientific way what they think is consciousness, you see this analysis phase, breaking it down in steps to the bare minimum. From a scientific point of view, this makes perfect sense. This leads to two pounts of view - scientific, leading to reduction and more philosophic - there's no way to describe it since it is _super-natural_. I lean to the more scientific approach, we are not more and not less than the sum of our parts and, each of our parts, at any sub-scale, has some resemblance to a thermostat: some object that reacts on its environment.
mannykannot 2y ago
I feel that there is an alternative way of approaching the question: to propose that it is only meaningful to ask what it is like to be an X if the X has certain mental abilities, such as some sort of self-awareness of itself as a participant in a wider world. How would we go about evaluating and choosing between these two views, and is there room for there being degrees of 'what it is like' and self-awareness? It is almost as if we are trying to write the dictionary definition before we know enough to complete the job (which is not necessarily a bad thing, unless we assume that by making a choice, we have, ipso facto, filled in the previously-incomplete knowledge.) I definitely take issue with Chalmers' opening sentence of his final paragraph: "… A final consideration in favor of simple systems having experience: if experience is truly a fundamental property, it seems natural for it to be widespread." I feel he is putting the cart before the horse here - something that seems quite common in the philosophy of mind - by first deciding that experience is a fundamental property, and then using it to justify the assumption that it is widespread. This strikes me as almost circular, as it seems one could at least as reasonably justify it being fundamental on account of the arguments for it being ubiquitous.
- robwwilliams 2y ago
  You are so right! Both circular and if you follow through in a cartesian mode you end up with an infinite stack of “representations” all the way up toward the two neurons that “represent” your two grandmothers. Both Richard Rorty (Philosophy and the Mirror of Nature) and Daniel Dennett (almost any of his works) did us a big favor by demolishing representational dualism—-mind vs brain.
HarHarVeryFunny 2y ago
It's a dumb click-bait title (riffing on Nagel's "What is it like to be a bat?"), but the actual question presented a bit further down is: "Moving down the scale through lizards and fish to slugs, similar considerations apply. There does not seem to be much reason to suppose that phenomenology should wink out while a reasonably complex perceptual psychology persists… As we move along the scale from fish and slugs through simple neural networks all the way to thermostats, where should consciousness wink out?" The author seems to have succeeded in answering her own question (at least in hand-wavy fashion) at the same time as posing it, as well as implicitly defining consciousness. So, yeah, it's not like anything to be a thermostat.
- robwwilliams 2y ago
  Perfect!
- cubefox 2y ago
  Surely you agree that not only thermostats are not conscious, but also simple neural networks are not. E.g. a single layer perceptron. And it's intuitively also not just a matter of number of layers or neurons. By the way: The headline is, I assume, by Annaka Harris, while the essay is by David Chalmers.
  - HarHarVeryFunny 2y ago
    > Surely you agree that not only thermostats are not conscious, but also simple neural networks are not Sure - there is a difference between merely being cold and also being aware of being cold. A piece of ice (or a cold thermometer for that matter) can be cold, but to experience being cold - to be aware/conscious of it - requires some minimal level of cognitive apparatus ("a reasonably complex perceptual psychology") to process those sensory inputs and contrast them to the differing sensation of not being cold and be able to think about it! There is some evidence, such as "blindsight" (ability to see without being aware of it - a loss of visual consciousness) that consciousness may not only require the mental apparatus to process a sensory input, but may also require specific neural pathways (which may be missing, or damaged) to gain access to specific internal neural state in the first place. It's difficult to know exactly where the line is - which animals do have a sufficiently complex brain to able to introspect on and experience their own state, but clearly simple neural nets (e.g. anything without feedback paths) don't, and simple animals like insects don't either.
mensetmanusman 2y ago
If you believe a thermostat has consciousness, you would also logically believe that the cascading subset of (your body - n*atoms) would also be conscious. E.g. your arm. This is one reason the topic is so slippery.

  And if a thermostat is conscious, then so would an alarm clock be...

I think that we find the idea of thermostat having experiences strange because, subconsciously, we think of experiences only being accessible to someone / something that has a "will to live" (in the words of Schopenhauer). I.e. I don't think thermostats want anything. They don't have a capacity to care whether they fall apart or not, whether anyone is satisfied with their function or not. But, life, even in the very simplest form wants something. Experiences to living organisms is what makes them more effective at doing what they want. What makes living creatures want something: I have no idea. I remember hearing a hypothesis tying this to better preservation of energy... but I don't know about that. But, if I had to guess, it must be something that's available to micro-organisms, so, it has to have some physical / chemical explanation...
- nuancebydefault 2y ago
  Maybe the property of "wanting" is no more than survivorship bias? Since living things survive, they must have a "will" to survive. Maybe that will is just a label that humans invented to attribute to living things?
  - crabbone 2y ago
    Well, wouldn't this bias happen a while ago, to the very primitive organisms? Because the organisms we see today seem to universally want to live. I mean, even if we somehow mislabeled some more fundamental property, on the face of it, it seems to be pretty consistent. Everything about how these organisms are built is indicative of their "will" to remain functional and to procreate. Eg. regrowing parts of organism's body in order to overcome damage (that would cause the organism to cease to exist) seems pretty universal. Similarly, trying to move away from hostile environments seems to be pretty built-in feature of anything alive.
    - nuancebydefault 2y ago
      Indeed it makes sense that very primitive organisms had it and passed it on via DNA or even some other form of chemical code. Still some DNAs were flawed and other had more advanced survival techniques. Still that boils down to: survival has to be a property (or even the definition?) of life. So maybe the question of life introduction is, when did survivorship emerge?
neogodless 2y ago
Their use of "phenomenal" and "phenomenology" confuses me as a layman, but I'll lay out their (likely relevant) definitions and hope to use that to better understand what is being proposed. > phenomenal: Known or derived through the senses rather than through the mind. > phenomenology: A philosophy or method of inquiry based on the premise that reality consists of objects and events as they are perceived or understood in human consciousness and not of anything independent of human consciousness. So the claim (highlighted especially in paragraph 3) is that, outside of humans, things that are perceived may also exist in conscious thought (of non-humans).
isoprophlex 2y ago
Another useful metaphor that doesn't cross the threshold from human experience into the "experiencing" that non-living things do, would be chemotaxis. A bacterium finds food with a simple set of states. At it's most basic: - you are experiencing an increasing concentration of food. you keep swimming straight ahead. - you are experiencing a decreasing concentration of food. you move in a continuously randomized direction. this eventually gets them onto a track where they are moving towards food. Extremely simple like a thermostat, yet effective. https://en.m.wikipedia.org/wiki/Chemotaxis https://en.m.wikipedia.org/wiki/Chemotaxis
- robwwilliams 2y ago
  No, not like a thermostat. A bacterium is a compact and exceedingly complex living system. It has autopietic autonomy like we do. The fact the I navigate each morning to the refrigerator to get milk for breakfast is not so different from a bacterium following a gradient toward its food. Bacteria have complex receptors like we do that are their sensorium—-a nano-brain in the words of one scientist who studies their behavior.
  - primes4all 2y ago
    And yet, also a thermostat is doing nothing else but following a gradient towards a desired state (albeit the gradient is discrete and it's moving along the dimension of temperature).
    - jamieplex 2y ago
      Except that a thermostat doesn't "follow" anything. It is basically a binary response state: on or off (or high and low). Nothing further. Analog or digital, it doesn't follow anything.... It reacts instantly at a setpoint. Would you think an alarm clock is "following" the time, and turns the alarm on at the set time? Or is it a momentary switch at a setpoint....
luxuryballs 2y ago
anyone know what font that is? (on mobile) reminds me of like an old 70s print
robwwilliams 2y ago
Chalmers is a dualist living in a Cartesian past. If you like a lively treatment of dead scholasticism of the mind-vs-brain problem then you can do no better. Ditto Nagel. In contrast if you want modern post-cartesian scientific thought on consciousness then hit Dennett hard for philosophy or Ray W. Guillery if you want hard neuroscience (The Brain as a Tool).
ruthmarx 2y ago
For it to be 'like' to be anything, the anything must have some send of self. Without a sense of self, there is just information processing. For that reason, it isn't 'like' anything to be, say, most insects, let alone a thermostat.
- rcxdude 2y ago
  The trouble there is that people can experience altered states of consciousness where they are still aware, but lose that sense of self. It's hard to call that state unconscious, but it's also without self-awareness.
mode80 2y ago
I remember inspecting the thermostat in my parent’s house as a child. It was a coil of something metalic which I assume expands and contracts with temperature and physically pushes electrical contacts together to turn on the heat when needed. Knowing how it works, it’s hard for me to imagine that this feels like anything. The whole contraption is just an arrangement of molecules doing what molecules do. But then again, so am I.
ryandvm 2y ago
"What is it like to be a bat (or a thermostat)?" is too abstract for anyone to thoughtfully grasp. Instead try asking yourself "what is it like to be asleep?" or "what is it like to be waking up?" or "what is it like to be heavily sedated?" We all experience various gradients of consciousness every day as we do things like drift off to sleep or slowly gain consciousness in the morning. You don't have to try to imagine the experience of another primitive life form when you can just recall what there is or isn't to your own conscious experience as you drift between states.

I find Thomas Nagel's "what it is like to be" [1] concept fascinating. I have spent quite some time trying to imagine what it is like to be a rock. Mind you, not from the perspective of a human ("A rock will probably experience time very quickly, because it erodes, etc. etc"), but from the perspective of the rock itself. That is, it has no senses, no memory, no capabilities for abstraction, no consciousness. This ruminating has led me to believe that time and logic are human concepts, and are not as universal as is commonly believed. With recent insights into neural networks, I wouldn't even be surprised if the laws of physics follow from the way our brains are wired, instead of the other way around.

I can recommend Being No One, by Thomas Metzinger, for essays. For sci-fi, have a look at Blindsight, by Peter Watts (for free on his website: Https://www.rifters.com/real/Blindsight.html)
- smokel 2y ago
  Thanks for the recommendations! I have read Thomas Metzinger's Ego Tunnel (2009), but as far as I understand it, he takes on a naturalist standpoint, and assumes that consciousness arises from that. I prefer to take a radical agnostic point of view, where consciousness does not even have meaning outside of those who experience it. Implying that "meaning" or "reasoning" make no sense universally.

1996

I find this interesting, and I think dates should always be included. But I have this question- why am I interested in the date? What changes in this message when I know the date? I feel like knowing the date sets up a conflict between "this is out of date" vs. "this is before the era of mass garbage generation" (more generously described as "with time only the classics survive)
- mannykannot 2y ago
  There has been much debate since this was written, but not much movement towards a consensus.
- cubefox 2y ago
  Chalmers also may have changed his view in the past 28 years.
  - robwwilliams 2y ago
    I wish. This kind of showboating in 1996 is what allowed him to achieve his professional goal—-to be the modern voice of archaic Cartesian dualism. There actual is no hard problem. Ask neuroscientist “What is the hard problem” and you will get blank stares. They just do not know, or like me, do not care. It is a muddy residue of Cartesian dualism. Boring.
    - cubefox 2y ago
      That's not convincing to me. If you say some problem "doesn't exist", I need an argument which makes a compelling case for that, which presents some kind of dissolution.

Title reminds me of Tim Hunkin's BBC series "The Secret Life of Machines", which he's put on YouTube. There is, funnily enough, an episode on central heating systems: https://www.youtube.com/watch?v=PnQ9zkBzbYc https://www.youtube.com/watch?v=PnQ9zkBzbYc EDIT: there is of course a bit about thermostats: https://www.youtube.com/watch?v=PnQ9zkBzbYc&t=1137 https://www.youtube.com/watch?v=PnQ9zkBzbYc&t=1137

johann8384 2y ago

Wouldn't the thermostat be more closely aligned with a nerve in the overall system and the control board be more aligned as the brain? The brain can get signals from multiple thermostatats in a system to control the temperature.

upghost 2y ago

Does anyone know of a smart thermostat that actually has this function? Every thermostat I've looked for has "heat mode" where it decides if it should be blasting heat or not, and "cool mode", where it decides it should be blasting the AC or not. I have not found the mythical smart thermostat that does the job of "keep the temperature around here" +/- a few degrees. I live in an area where its cold at night and hot during the day and I am bad at remembering to change the thermostat from mode to mode and haven't found a programmable IOT thermostat I can write a script for, recommendations welcome!

ajoberstar 2y ago
Nest thermostats have a heat and cool mode where you have setpoints for each. On older ones there was a limit on how close the two could be set.
ewhanley 2y ago
Ecobee thermostats can run in dual heat/cool mode
toast0 2y ago
Echoing the other responses, Nest and Ecobee both have this feature, and I think it may have been on the Sensi as well, but I only had a furnace then. Some basic thermostats can do this too.
rcxdude 2y ago
It tends to be tricky to do this without wasting a lot of power, most thermostat auto modes have a pretty wide spread of maximum and minimum temperature because otherwise you run the risk of oscillating between using energy to heat and using energy to remove the heat you've just added. It can be done care and tuning, but the average home HVAC setup is not designed or installed with care.

tananan 2y ago

This kind of panpsychistic talk to me ends up feeling more closer to a reductive materialism than what I would firstly associate Chalmers with ("hey, did you forget you can experience stuff?"), which is probably just my ignorance with his work. Because yes, you acknowledge "experience", but you make it a function of a physical state described in such and such a way. In the same way that a set of particles at points A, B, C, .. correspond to such and such a (e.g. electric) field strength at point Z, we now imagine it could correspond also to such and such an experience. It's just barely "experience" on its own terms. and elicits a kind of epiphenomenalism and powerlesness. The thermostat*, after all, doesn't choose anything nor does it profess to have any agency. So agency ought to end up some kind of ephiphenomenal "observable" of a system. But besides being deflationary in this distasteful way, what bothers me with pictures like this is that they make use of entirely subject-made divisions between objects and their environments, and presume that they might correspond to experiences because - why not? Why not thing of the bottom and upper half of thermostat as corresponding to two fields of experience? Or the quarters, sixtheents, and so on until we get to individual atoms. The thermostat doesn't "care" if I think of it as the wax and glass separately, or as a single object containing both. But we do have a unified field of experience, and it doesn't matter how another person "cuts us up" in their mind, whether it is as atoms interacting, organs behaving in unison, or just as a "body". It seems silly to say that between me and Bob having our separate experiences, there is an experience corresponding to "me and Bob", supposedly free-floating somewhere just by virtue of the two of us being cognizable as a physical system. It turns "experience" and that infamous "qualia" from something that's the most direct and obvious to a weird phantom as the output of a presumed equation which maps some description of a physical state to an "experience". No wonder you'll find people who'll retort that they don't experience things or that their consciousness is illusory - they have these weird detached notions of experiences to fight against. * I imagined a thermometer throughout reading this piece, hence the mention of wax and such. It doesn't really change the point so I'm leaving it.

nuancebydefault 2y ago
Each time someone tries to explain in a scientific way what they think is consciousness, you see this analysis phase, breaking it down in steps to the bare minimum. From a scientific point of view, this makes perfect sense. This leads to two pounts of view - scientific, leading to reduction and more philosophic - there's no way to describe it since it is _super-natural_. I lean to the more scientific approach, we are not more and not less than the sum of our parts and, each of our parts, at any sub-scale, has some resemblance to a thermostat: some object that reacts on its environment.

mannykannot 2y ago

I feel that there is an alternative way of approaching the question: to propose that it is only meaningful to ask what it is like to be an X if the X has certain mental abilities, such as some sort of self-awareness of itself as a participant in a wider world. How would we go about evaluating and choosing between these two views, and is there room for there being degrees of 'what it is like' and self-awareness? It is almost as if we are trying to write the dictionary definition before we know enough to complete the job (which is not necessarily a bad thing, unless we assume that by making a choice, we have, ipso facto, filled in the previously-incomplete knowledge.) I definitely take issue with Chalmers' opening sentence of his final paragraph: "… A final consideration in favor of simple systems having experience: if experience is truly a fundamental property, it seems natural for it to be widespread." I feel he is putting the cart before the horse here - something that seems quite common in the philosophy of mind - by first deciding that experience is a fundamental property, and then using it to justify the assumption that it is widespread. This strikes me as almost circular, as it seems one could at least as reasonably justify it being fundamental on account of the arguments for it being ubiquitous.

robwwilliams 2y ago
You are so right! Both circular and if you follow through in a cartesian mode you end up with an infinite stack of “representations” all the way up toward the two neurons that “represent” your two grandmothers. Both Richard Rorty (Philosophy and the Mirror of Nature) and Daniel Dennett (almost any of his works) did us a big favor by demolishing representational dualism—-mind vs brain.

HarHarVeryFunny 2y ago

It's a dumb click-bait title (riffing on Nagel's "What is it like to be a bat?"), but the actual question presented a bit further down is: "Moving down the scale through lizards and fish to slugs, similar considerations apply. There does not seem to be much reason to suppose that phenomenology should wink out while a reasonably complex perceptual psychology persists… As we move along the scale from fish and slugs through simple neural networks all the way to thermostats, where should consciousness wink out?" The author seems to have succeeded in answering her own question (at least in hand-wavy fashion) at the same time as posing it, as well as implicitly defining consciousness. So, yeah, it's not like anything to be a thermostat.

robwwilliams 2y ago
Perfect!
cubefox 2y ago
Surely you agree that not only thermostats are not conscious, but also simple neural networks are not. E.g. a single layer perceptron. And it's intuitively also not just a matter of number of layers or neurons. By the way: The headline is, I assume, by Annaka Harris, while the essay is by David Chalmers.
- HarHarVeryFunny 2y ago
  > Surely you agree that not only thermostats are not conscious, but also simple neural networks are not Sure - there is a difference between merely being cold and also being aware of being cold. A piece of ice (or a cold thermometer for that matter) can be cold, but to experience being cold - to be aware/conscious of it - requires some minimal level of cognitive apparatus ("a reasonably complex perceptual psychology") to process those sensory inputs and contrast them to the differing sensation of not being cold and be able to think about it! There is some evidence, such as "blindsight" (ability to see without being aware of it - a loss of visual consciousness) that consciousness may not only require the mental apparatus to process a sensory input, but may also require specific neural pathways (which may be missing, or damaged) to gain access to specific internal neural state in the first place. It's difficult to know exactly where the line is - which animals do have a sufficiently complex brain to able to introspect on and experience their own state, but clearly simple neural nets (e.g. anything without feedback paths) don't, and simple animals like insects don't either.

mensetmanusman 2y ago

If you believe a thermostat has consciousness, you would also logically believe that the cascading subset of (your body - n*atoms) would also be conscious. E.g. your arm. This is one reason the topic is so slippery.

jamieplex 2y ago
And if a thermostat is conscious, then so would an alarm clock be...

I think that we find the idea of thermostat having experiences strange because, subconsciously, we think of experiences only being accessible to someone / something that has a "will to live" (in the words of Schopenhauer). I.e. I don't think thermostats want anything. They don't have a capacity to care whether they fall apart or not, whether anyone is satisfied with their function or not. But, life, even in the very simplest form wants something. Experiences to living organisms is what makes them more effective at doing what they want. What makes living creatures want something: I have no idea. I remember hearing a hypothesis tying this to better preservation of energy... but I don't know about that. But, if I had to guess, it must be something that's available to micro-organisms, so, it has to have some physical / chemical explanation...

nuancebydefault 2y ago
Maybe the property of "wanting" is no more than survivorship bias? Since living things survive, they must have a "will" to survive. Maybe that will is just a label that humans invented to attribute to living things?
- crabbone 2y ago
  Well, wouldn't this bias happen a while ago, to the very primitive organisms? Because the organisms we see today seem to universally want to live. I mean, even if we somehow mislabeled some more fundamental property, on the face of it, it seems to be pretty consistent. Everything about how these organisms are built is indicative of their "will" to remain functional and to procreate. Eg. regrowing parts of organism's body in order to overcome damage (that would cause the organism to cease to exist) seems pretty universal. Similarly, trying to move away from hostile environments seems to be pretty built-in feature of anything alive.
  - nuancebydefault 2y ago
    Indeed it makes sense that very primitive organisms had it and passed it on via DNA or even some other form of chemical code. Still some DNAs were flawed and other had more advanced survival techniques. Still that boils down to: survival has to be a property (or even the definition?) of life. So maybe the question of life introduction is, when did survivorship emerge?

neogodless 2y ago

Their use of "phenomenal" and "phenomenology" confuses me as a layman, but I'll lay out their (likely relevant) definitions and hope to use that to better understand what is being proposed. > phenomenal: Known or derived through the senses rather than through the mind. > phenomenology: A philosophy or method of inquiry based on the premise that reality consists of objects and events as they are perceived or understood in human consciousness and not of anything independent of human consciousness. So the claim (highlighted especially in paragraph 3) is that, outside of humans, things that are perceived may also exist in conscious thought (of non-humans).

isoprophlex 2y ago

Another useful metaphor that doesn't cross the threshold from human experience into the "experiencing" that non-living things do, would be chemotaxis. A bacterium finds food with a simple set of states. At it's most basic: - you are experiencing an increasing concentration of food. you keep swimming straight ahead. - you are experiencing a decreasing concentration of food. you move in a continuously randomized direction. this eventually gets them onto a track where they are moving towards food. Extremely simple like a thermostat, yet effective. https://en.m.wikipedia.org/wiki/Chemotaxis https://en.m.wikipedia.org/wiki/Chemotaxis

robwwilliams 2y ago
No, not like a thermostat. A bacterium is a compact and exceedingly complex living system. It has autopietic autonomy like we do. The fact the I navigate each morning to the refrigerator to get milk for breakfast is not so different from a bacterium following a gradient toward its food. Bacteria have complex receptors like we do that are their sensorium—-a nano-brain in the words of one scientist who studies their behavior.
- primes4all 2y ago
  And yet, also a thermostat is doing nothing else but following a gradient towards a desired state (albeit the gradient is discrete and it's moving along the dimension of temperature).
  - jamieplex 2y ago
    Except that a thermostat doesn't "follow" anything. It is basically a binary response state: on or off (or high and low). Nothing further. Analog or digital, it doesn't follow anything.... It reacts instantly at a setpoint. Would you think an alarm clock is "following" the time, and turns the alarm on at the set time? Or is it a momentary switch at a setpoint....

Chalmers is a dualist living in a Cartesian past. If you like a lively treatment of dead scholasticism of the mind-vs-brain problem then you can do no better. Ditto Nagel. In contrast if you want modern post-cartesian scientific thought on consciousness then hit Dennett hard for philosophy or Ray W. Guillery if you want hard neuroscience (The Brain as a Tool).

ruthmarx 2y ago

For it to be 'like' to be anything, the anything must have some send of self. Without a sense of self, there is just information processing. For that reason, it isn't 'like' anything to be, say, most insects, let alone a thermostat.

rcxdude 2y ago
The trouble there is that people can experience altered states of consciousness where they are still aware, but lose that sense of self. It's hard to call that state unconscious, but it's also without self-awareness.

mode80 2y ago

I remember inspecting the thermostat in my parent’s house as a child. It was a coil of something metalic which I assume expands and contracts with temperature and physically pushes electrical contacts together to turn on the heat when needed. Knowing how it works, it’s hard for me to imagine that this feels like anything. The whole contraption is just an arrangement of molecules doing what molecules do. But then again, so am I.

ryandvm 2y ago

"What is it like to be a bat (or a thermostat)?" is too abstract for anyone to thoughtfully grasp. Instead try asking yourself "what is it like to be asleep?" or "what is it like to be waking up?" or "what is it like to be heavily sedated?" We all experience various gradients of consciousness every day as we do things like drift off to sleep or slowly gain consciousness in the morning. You don't have to try to imagine the experience of another primitive life form when you can just recall what there is or isn't to your own conscious experience as you drift between states.
