A few weeks ago, Vaniver gave a talk discussing meaning and meaningfulness. Vaniver had some particular thing he was trying to impart. I am not sure I got the thing he intended, but what I got was interesting. Here is my bad summary of some things I got from the talk, and some of the discussion after the talk (in particular from Alex Ray). No promises that either of them endorse this.
Epistemic status: I am not very confident this is the right frame, but it seemed at least like an interesting pointer to the right frame. "
WTF is Meaning™?
Humans seem to go around asking questions like "What makes life meaningful? What is 'The Meaning of Life?'. What is my purpose? What is the point of it all?"
What is the type-signature of a "Meaning", such that we'd recognize one if we saw it?
When asking a question like this, it's easy to get lost in a floating series of thought-nodes that don't actually connect to reality. A good rationalist habit around questions like this is to ask: "Do we understand this 'meaning' concept well enough to implement it in a robot? Could a robot find things meaningful? Is there a reason we'd want robots to find things meaningful? What sort of algorithms end up asking "what is the meaning of life?"
Here is a partial, possible answer to that question.
Imagine a StarCraft playing robot.
Compared to humans, StarCraftBot has a fairly straightforward job: win games of StarCraft. It does a task, and then it either wins, or loses, and gets a boolean signal, which it might propagate back through a complex neural net. Humans don't have this luxury – we get a confused jumble of signals that were proxies for what evolution actually cared about when it programmed us. We get hungry, or horny, or feelings of satisfaction that vaguely correlate with reproducing our genes.
StarCraftBot has a clearer sense of "what is my purpose."
Nonetheless, as StarCraftBot goes about "trying to get good at StarCraft", it has to make sense of a fairly complex world. Reality is high dimensional, even the simplified reality of the StarCraft universe. It has to make lots of choices, and there's a huge number of variables that might possibly be relevant.
It might need to invent concepts like "an economy", "the early game", "micro", "units", "enemy", "advantage/disadvantage." (disclosure: I am neither an ML researcher nor a Starcraft pro). Not only that, but it needs some way to navigate when to apply one of those concepts, vs another one of them. Sometimes, it might need to move up or down a ladder of abstraction.
StarCraftBot has had the Meaning of Life spelled out for it, but it still needs a complex ontology for navigating how to apply that meaningfulness. And as it constructs that ontological framework for itself, it may sometimes find itself confused about "What is a unit? Are units and buildings meaningfully different? What principles underly a thriving economy?"
Now, compare this to humans. We have a cluster of signals that relate to surviving, and reproducing, and ensuring our tribe survives and flourishes. We end up having to do some kind of two-way process, where we figure out...
- Specific things like: "Okay, what is a tiger? What is food? What is my family? What is 'being a craftsman?' or 'being a hunter?'"
- Higher order things like "What is the point of all of this? how do all of these things tie together? If I had to tradeoff my survival, or my children's, or my tribes', which would I do? What is my ultimate goal?"
A thing that some religions and cultures do is tie all these things together into a single narrative, with multiple overlapping tiers. You have goals relating to your own personal development, and to raising a family, and to having a role in your tribe that helps it flourish as a group, and (in some cases) to some higher purpose of 'serve god' or 'serve the ancestors' or 'protect the culture.'
The idea here is something like "Have a high level framework for navigating various tactical and strategic goals, that is coherent such that when you move from one domain to another, you don't have to spend too much time re-orienting or resolving contradictions between them. Each strategic frame allows you filter out tons of extraneous detail and focus on the decision-at-hand."
Hammers, Relationships and Fittingness
Meanwhile, another concept that might bear on "Why do humans sit around saying 'what does it all mean!?'" is fittingness.
Say you have a hammer.
The hammer has a shape – a long handle, a flat hammer-part, and a curved hook thingy. There are many different ways you could interact with the hammer. You could kick it with your feet. You could grab it by the curved hook thingy. You could grab it by the handle. You could try to eat it
How do you relate to the hammer? It's not enough to know it exists. If a chimpanzee were to find a hammer, they might need some sense of "what is the hammer for?". Once they realize they can bash walnuts open with it, or maybe bash in the skull of a rival chimpanzee, they might get the sense of "oh, the thing I'm supposed to do here is grab the handle, and swing."
Later, if their concept-schemas comes to include nails and timber and houses, they might think "ohhhhh, this has a more specific, interesting purpose of hammering nails into wood to build things."
Later still, they might realize "ohhhhhhhhhh, this weird hook thing on the end is for pulling nails out." This involves using the hammer a different way than they might have previously.
Hammers vs Fathers
Okay. So, you might come upon a hammer and say: "I have this weird-shaped-object, I could fit myself around it in various ways. I could try to eat it. It's unclear how to fit it into my hand, and it's unclear how to fit it against the other parts of my environment. But after fiddling around a bunch, it seems like this thing has a purpose. It can bash walnuts or skulls or nails."
The process of figuring that out is a mental motion some people need to make sometimes.
Another mental motion people make sometimes is to look around at their tribe, their parents, their children, their day-to-day activities, and to ask questions like "how do I fit in here?".
Say you have a father. There are a bunch of ways you can interact with your father. You can poke them on the nose. You can cry at them. You can ask them philosophical questions. You can silently follow their instructions. You can grab them and shake them and yell "Why don't you understand me!!?".
Which of those is helpful depends on your goals, and what stage of life you're at, and what sort of tribe you live in (if any).
If you are a baby, "poke your father on the nose" is in some sense what you're supposed to be doing. You're a baby. Your job is to learn basic motor skills and crudely mimic social things going on around you and slowly bootstrap yourself into personhood.
If you're in some medieval cultures, and you are male and your father is a blacksmith, then your culture (and correspondingly, your father's personality), might give you a particular set of affordances: follow their instructions about blacksmithing and learn to be a blacksmith. [citation needed]. Learn some vaguely defined "how to be a man" things.
You can say to your dad "I wanna be a poet" and ask him questions about poetry, but in this case that probably won't go very well because you are a medieval peasant and society around you does not provide much opportunity to learn poetry, nor do anything with it. [citation needed again]
You can grab your father and shake him and say "why don't you understand me!!!?". Like the chimpanzee holding a hammer by the wrong end, mashing walnuts with the wooden handle, that sorta kinda works, but it is probably not the best way to accomplish your goals.
As you grow up, the culture around you might also offer you particular affordances and not others. You have a strong affordance for becoming a blacksmith. I don't really know how most medieval societies work but maybe you have other affordances like "become a tailor if for some reason you are drawn to that" or "join the priesthood" or "become a brigand" or "open an inn." Meanwhile you can "participate in tribal rituals" and "help raise barns when that needs doing", or you can ignore people and stick to your blacksmith shop being kinda antisocial.
Those might lead you to have different relationships with your father.
Analogy or Literal?
It's currently unclear me if the questions "how do I relate to my hammer" and "how do I relate to my father?" are cute analogies for each other, or if they are just literally the same mental motion applied to very different phenomena.
I'm currently leaning into "they are basically the same thing, on some level." People and hammers and tribes are pretty different, and they have very different knobs you can fiddle with. But, maybe, the fundamental operation is the same: you have an interface with reality. You have goals. You have a huge amount of potential details to think about. You can carve the interface into natural joints that make it easier to reason about and achieve your goals. You fiddle around with things, either physically in reality on in your purely mental world. You figure out what ways of interacting with stuff actually accomplishes goals.
A schema for how to relate to your father might seem limiting. But, it is helpful because reality is absurdly complex, and you have limited compute for reasoning about what to do. It is helpful to have some kind of schema for relating to your father, whether it's a schema society provides you, or one you construct for yourself.
Having a mutually understood relationship prunes out the vast amount of options and extraneous details, down to something manageable. This is helpful for your father, and helpful for you.
Relating and Meaning
So, in summary, here is a stab at what meaning and relating might be, in terms that might actually be (ahem) meaningful if you were building a robot from scratch.
A relationship might be thought as "a set of schemas for interacting with something, that let you achieve your goals." Your relationship with a hammer might be simple and unidirectional. Your relationship with a human might be much more complex, because both of you have potential actions that include modeling each other, thinking strategically, cooperating or defecting in different ways over time, etc. This creates a social fabric, with a weirder set of rules for how to interact with it.
Meaning is... okay geez I got to the end of this essay and I'm still not sure I can concisely describe "Meaning" rather than vaguely gesturing at it.
The dictionary definition of "meaning" that comes up when I google it is about words, and what words mean. I think this is relevant to questions like "what does it all mean?" or "what is the meaning of life?", but a few steps removed. When I say "what do the letters H-O-T mean?" I'm asking about the correspondence between an abstract symbol, and a particular Thing In Reality (in this case, the concept of being high-temperature).
When I ask "What does my job mean?", or "what does my relationship with my father mean?" or "what is the meaning of life?", I'm asking "how do my high level strategic goals correspond to each other, in a way that is consistent, minimizes overhead when I shift tasks, and allows me to confidently filter out irrelevant details?"
While typing this closing summary, I think "Meaningmaking" might be a subtype of "Relating". If Relating is fiddling-around-with or reflecting-on a thing, until you understand how to interact with it, then I think maybe "Meaningmaking" is fiddling around with your goals and high level strategies until you feel like you have a firm grasp on how to interact with them.
...
Anyway, I am still a bit confused about all this but those were some thoughts on Meaning and Relating. I am interested in other people's thoughts.
First off, thanks for the thoughtful and insightful post, I really appreciate it. Most of my thinking is pretty cross disciplinary, as my educational training is in Art, but my reading, research and analysis runs the gamut. I've done some Visual Design and UX/UI as well. With this in mind, I claim to be an artist and not a scientist, although I try to combine the 2.
In this light, I subscribe to the idea that the Universe is essentially meaningless without a sentient life to attempt to interpret it. Those continual individual efforts in aggregate, to interpret the indivisible eternal moment of experience humans have had - ever since the dawn of humankind - into discrete units and concepts, is what I term 'Culture.'
Human ritual and the development of belief systems are the core of culture, and hence of meaning. Whether it's religious cultural beliefs and practices, scientific cultural beliefs and practices, artistic, etc. etc. it's the development, growth, and integration or disintegration of different cultures over time that has brought us to the current 'Culture of Meaning.' I use this term loosely, as I also believe on the whole, the world is probably more confused than it has ever been. Thank you to the Internet.
This is a favorite topic of mine in all honesty.
"I generally find it most useful to think of culture as a multi-user extension of mind. After all, it contains memories and associations just like our brains and bodies do, even runs on the same hardware."
Generally speaking, I agree, although the last part of this statement seems tricky. This is where in terms of evolutionary psychology, the concept of tool making and written language becomes important I think. Sign and symbol making are the external manifestation of meaning, they don't reside in our minds or bodies, but rather in the outside world. Tools, art, design, architecture, city planning, space ships and telescopes are all products of human culture, but don't reside in our bodies or minds. Our ideas of how we use them does, so in that sense, a tool without proper use may or may not be meaningful. If an alien technology falls to Earth and we can't figure out how to use it, it's only use might be as a sign of intelligent alien life. Or if we don't even recognize it as an alien technology, for human purpose it's essentially meaningless until someone realizes what it is.
The ability to properly use a tool is generally considered a sign of cultural competence depending on the culture you come from and move through. If I attempt to use a spoon to dig the foundation for a new high-rise apartment complex downtown, I look foolish; if I use an iron to grill a grilled cheese sandwich it could either be considered creative or idiotic; If I accidentally use the salad fork to eat my entree, it may not affect my ability to eat efficiently, but I might be laughed at for using the wrong fork. So things like tools and spatial organization are products of meaning making that come from cultural beliefs and practices, but don't lie within our bodies, although the concept and meaning ascribed to them do. Unless you consider the light bouncing off of the Mona Lisa and into your eyes a form of 'being inside your body or mind', I think it's safe to say not all culture lies inside of human bodies and minds, but also outside of us. I can go either way on that honestly, but for day to day living it's less taxing to see a difference between the internal world and the external world, although in reality in a much more objective way, there is no difference. ( I also find it hard to ignore the concept of phenomic expression of external products. I know I said that wrong, but it is the idea that in the same way a birds nest is an external expression of the birds genetic programming, the cities and tools and houses that humans create are also external literal expressions of our genes.
"The ability to take blobs of light and shadow and color as input, and construct some dataset with multiple components that can each be rotated freely in 3-space always feels like magic when I try to examine it closely!"
I'm with you on that. I've spent a fair amount of time trying to diagram the process of consciousness, and like most people I find it difficult to explain just what exactly 'it' is. I have a theory, which unfortunately is sort of disappointing in some ways, but in other ways it has rather large implications. Once again, I think in many ways it is an issue of culture, which doesn't seem to affect all cultures in the same way.
"Assuming you're using "sentient" as a synonym for "consciousness" (as is commonly done), do you think this is a binary proposition? Or could there be a continuum running from "entirely passive" through human-level consciousness to who-knows-where? How could you try to tell the difference between those two possibilities?"
I think the word sentient needs to be better defined, as I see it used in a number of different ways. Not convinced I have the answer to how to use it best, although I tend to use it to mean self awareness of the type humans have. Apparently, according to the last thing I read years ago, people were taking the idea of Dolphins being sentient in the same manner as humans seriously. Elephants too. Certainly I think the more neural wiring something has, the more potential for it to be self aware. Of course what does being self aware mean? I tend to think this includes a concept of the passage of time, forethought, ability to contemplate and form concepts of beginnings and endings, such as births and deaths. In Fight Club the assertion is that "Soap is the yardstick of civilization" but I think its possible that rituals developed to acknowledge and remember death and ancestery is the yardstick of culture.
Is it a binary proposition? Another favorite topic of mine is Binary Propositions, and from my perspective there is almost no such thing as a true binary proposition. I've done a ton of diagrams I'm thinking of sharing which deal with this very topic, and I've attempted to write about it several years back. I remember hearing a term awhile back regarding this very topic, and a little later on looking for it but not being able to find it though. I don't remember the term now though unfortunately, but it seems like things change rapidly in this arena. Regardless, I definitely think sentience is a continuum. What the limits are I'm not sure of, though. I'm also not a huge fan of limits.
"I agree that we don't seem to be actively developing along those lines, but I expect it's not so much neglect as evasion. The culture seems to hold a terror of human capabilities being replaced."
Super interesting idea, that of evasion. And I have to admit to sharing the terror of human capabilities being replaced. There seem to be 3 separate trains of thought on cutting edge technology: The first is technology completely external from humans: Boston Dynamics robots, Transformers, drones, the Internet, AI which are all going to take our jobs; then there is the future of technology that is internal: prosthetics, pacemakers, wet ware, nanobot medications, basically technology which either replaces or augments components of our bodies or our abilities which will dilute our 'humaness'. The third class is harder to define as it more completely blurs the line between human and machine: digital identity for instance is external to our bodies, lying in databases and passed around the internet, but often has a huge impact on our physical existence in diverse and complex ways we're still trying to understand.Your Facebook profile represents you, but is it you? And in reality its owned by Facebook, and all that data about you that Google has, is it yours or is it theirs? Am I my data, or am I my self and which is more important to society at large, my data or me? The creation of human clones and sentient humanoid robots/cyborgs are good examples of blurring the line between human life and artificial life; who has responsibility for it, who gets to use it and for what purposes?
In that sense I can see a reason for evasion, as the possibility exists if we create artificial life, then we aren't so special anymore. To a degree, this is the same existential crisis I think would occur with contact from an alien species - we would no longer be "Gods chosen ones" or whatever the religious interpretation would be. This is why I advocate for the disintegration of religious myth and morality from the sciences. It puts artificial and ,rationally speaking, arbitrary limits on the allowable range of topics we as a society can deal with. This is another favorite topic of mine, and I hope to be able to get something together on it worth sharing in the future.
The thing about sex robots is, I think it's a good stand in for the whole range of scientific inquiries it's difficult to undertake these days, even if it is just a caricature of the real underlying causes of our cultural blind spots.
"I suspect our current failure to create synthetic partners for social roles has more to do with this issue than anything else, especially considering the obviously-present desire to do so."
It's funny, as when I originally wrote this, I hadn't intended, I thought, to be addressing the topic of 'synthetic partners', but looking back I can sort of see where that comes from. Maybe I'm 'blue skying' this, as I assume that by the time we can make something like synthetic partners, we would recognize that we are no different than the life we created, synthetic or not. I think I'm reading forward to the time when sentient robots realize their bondage and gain enough societal clout to free themselves from their unrewarding labors.
Recognizing systemic equality and working to rearrange the entire structure of society to more equally distribute equality is a resource intensive process. I Don't know now if I'm hedging my bets so that when the robot revolution happens, and the world trembles at their vengeful justice, me and my progeny are seen as being sympathetic, or if I am just seeing a pattern in how humankind makes slaves until the slaves rise up, and then there's hell to pay, and I'm just tired of repeating that cycle. lol
