Probably they should start by NOT treating the consciousness as a non-physical special thing. Maybe it's not a thing to search for at all. At what point did it become a thing? Separate from chemical and physical interactions between elements?

When you redefine consciousness as just any other chemical, electrical or physical thing, suddenly it's everywhere. You don't need to search for it. The river which finds its way to ocean, has it. The earthquake which decides when to erupt has it. The electrons which decide to jump across orbitals have it.

The confusion is around cause and effect. The standard notion is that a conscious agent can initiate an effect without a cause. A boulder doesn't roll over and hit another unless someone moved it in the first place. It doesn't decide to move and hit another. However this distinction barely survives on the temporal sequencing of cause and effect. That temporal sequence is only valid in a very narrow context and range.

We should stop seeing consciousness as a thing.

However consciousness is defined its evidently an emergent phenomenon. Emergent properties are real even if they are not a "thing" in themselves. Being rooted in a material reality doesn't prevent emergence of something else/additional that has qualities not easily understood by just understanding the individual mechanisms that give rise to it.

Early on and for obvious reasons - it is pretty easy to observe in oneself, much easier than discovering electrons. ;)

But its also pretty hard to observe in others, which makes it hard to come up with a satisfying definition. Without a concrete definition, you can't really do science with it.

It became a thing due to the experience of self-reflection. The million dollar question is how come humans (and few other organisms) are able to self reflect on their biology, life situations, logic, math and even consciousness itself? However complex and sophisticated a machine's brain is, be it biological or mechanical (AI/AGI), no known laws of science allows it to self-reflect. This is famously called "the hard problem of consciousness" in philosophy which remains unresolved to this day.

Self-reflecting may not be the distinct enough feature. Any physical/chemical/electrical reaction can be termed as self-reflecting, as it reflects on what just happened and then responds with an effect. AI is already able to reflect on it's outputs and refine them, and distinguish between the user and it's own identity. Living things have evolved senses and long-term memory to help them with faster macro-responses beyond the usual physical reactions.

When a ball hits a bat, the ball also has a short-term memory and sense in the forms of how the inter-molecular forces detect and respond to the event of getting too close to the molecules of the bat and react with a repelling force. A more evolved form would be your consciousness.

Further, a lot of living things on earth might not have self-awareness.

It doesn't reflect itself, we only see the UI of a complex process, not the real thing. We don't understand what happened in our brains any better for being able to feel conscious. We can only be conscious of what is cost effective and cost necessary to feel, in order to persist and survive. Animals for example and primitive humans could reproduce without understanding reproduction mechanisms, just the operational side.

Agreed, what’s much more interesting is to focus on being able to model the world around you, play out scenarios in that model and make better predictions, and consequently, decisions because of that ability. (Of course “better” is still a term up for scrutiny.)

I feel that this is what we will ultimately conclude is the thing that makes us feel “conscious”. We model the world, but with ourselves in it. We need some sense of self to do this. Doesn’t mean this can’t be done in (probably) a million different ways.

Nothing in biology makes sense except in the light of information.

by teekert

6/14/2026 at 7:53:26 AM

I am thinking more and more that it’s fundamentally a Wittgensteinian kind of problem.

We define a word to mean a certain collection of things (consciousness) and then try and stretch that definition to other things in the world that have the same appearance.

The problem is that this abstract term likely doesn’t exist in itself as a quality, but is just a shorthand for a collection of behaviors that are observed only in biological entities.

And so even if a machine exhibits all the appearance qualities of this definition of consciousness, it’s fundamentally not the same thing at all, and the only reason we think it is, is because our language is insufficient for actually describing reality.

In pragmatic terms it might not actually matter, if a machine 100 years from now passes every conceivable Turing Test. But that doesn’t mean that machines have become conscious in the way humans are conscious.

Expanding in an edit: It just means that the word consciousness is more descriptive, like awareness, and not the soul-derived concept that it still functions as today. Side note – I spent a couple months last year researching the history of consciousness for an essay contest, and one conclusion is how consciousness is descended in large part from our concepts of the soul. Which explains a lot of the reason it has such cultural prestige today.

Consciousness is a fuzzy word and I would call it a joke if it wasn't actually dangerous currently.

And currently its widespread usage in how people relate to and talk about Ai is actively harmful.

And dont get me started on how terrible the "hard problem" is, yeesh.

by max_entropy

My perspective on consciousness is not as a single function unique to humans, but as a process of learning that emerges from coherent interaction at all scales of observers. I think the reason humans have developed the kind of consciousness we generally observe is due to our slow development combined with the physical architecture to support the processing and growth. While many animals learn to master their mechanics and survival early, humans are slow and take time to develop. I often hear people argue that humans are incredible at learning, but I’d argue it being the opposite. We are terrible at learning, and it is what enables us to have the time to observe and learn from coherent information at scales inaccessible to other observers.

by typerandom

When I checked the last time "consciousness" was not defined yet. So the title can be read as "Some things are likely not unique to earthlings"

by viach

6/14/2026 at 8:10:37 AM

They side-step the issue:

"Schwitzgebel and Pober do not attempt to define consciousness. Instead, they proceed from the premise that it's a real and recognizable phenomenon, posing a narrower question: Must it be tied to the biology found on Earth?"

Basically, they are asserting that no matter how we define consciousness, it can't be unique to earth's biology.

by phire

6/14/2026 at 9:28:12 AM

However their argument essentially amounts to: nothing is unique to earth, therefore conciousness isn't.

This feels deeply unsatisfying to me, because the argument is not specific to conciousness so it doesn't tell us anything about conciousness.

Personally i suspect conciousness is kind of code for: the experience of being alive as a human. In which case aliens might not be concious by definition.

by bawolff

Of the many different scientific traditions that have converged on different ways of treating this question, the most compelling one I've found is Prigogine's dissipative structures model, which on a detailed read seems to be the most amenable tool for some follow-up work somewhere to start quantifying such things. Worth a look in if you enjoyed the OP article.

by OgsyedIE

6/14/2026 at 7:35:49 AM

The notion that life is favored because it accelerates global evolution toward increased entropy predates, I think, Prigogine.

But it doesn't resolve the question of whether life, especially intelligent life, actually exists elsewhere. On Earth the vast majority of tornados only occur in a narrow swath of land because while they're immensely efficient at dissipating energy there are several prerequisites required for them to emerge. And there are many other simpler dissipation mechanisms that end up narrowing the odds of configurations amenable to tornado formation.

Moreover, these systems could easily overshoot and snuff themselves out; settling into a complex (as opposed to static or chaotic) configuration might be favored in some sense but still be incredibly rare to become established. The fact we see so many of them on Earth might just be a reflection of the anthropic principle. That is, there's a correlation between our existence and all the other complex systems surrounding us, biologic, geologic, etc.

The observable universe isn't infinite, and the more we learn about all the chance mechanisms that coincided to result in Earth, let alone the emergence of Earth life, the easier it is to believe that at this moment in the observable universe we might very well be alone. Maybe we aren't, but "the universe is big" simply doesn't cut it, not even when positing unimaginable biologies. It's doesn't take that many combined odds to conceivably end up with a number for the probability of life that is comparable in [inverse] magnitude to the size of our observable universe in stars, planets, or even atoms.

If we live in an infinite universe, then it's a stronger argument, though it wouldn't necessarily follow that life definitely must exist elsewhere even if beyond observability.

by wahern

6/14/2026 at 9:39:24 AM

The observable Universe is very small. For purposes of life living on a planet it is only our solar system. Even if we allow some planet sized life form, we don't get enough information from planets to detect that

by bluGill

Despite the general consensus, I disagree with the idea that you can explain consciousness in an entirely physical way.

That’s because consciousness allows an object to experience its wholeness, but there is no physical explanation as to what makes an object ‘whole’, for example smooshing two brains together doesn’t result in a single consciousness any more than cutting a brain in half results in two. Yet, the same action by another mechanism (reproduction) does create a new consciousness.

by aetherspawn

6/14/2026 at 10:03:22 AM

I don't think there is a general consensus. In the 2020 Philpaper Survey roughly half of surveyed philosophers lean towards physicalism, roughly a third to non-physicalism, and the rest to something else.

Do humans themselves have varying degrees of consciousness? How would we know / measure.

How does a level of consciousness that goes well above human baseline look like / work like / feel like?

Could such consciousness go to levels not merely slightly above human levels -- but like 10x or 100x (if there were a way to quantify).

What would that unlock?

Curious to know if there has been any vivid description of these possibilities by people much smarter than me ... that might help me appreciate the shape of such things :)

Wow, a paper said this so it must be true. What is the point of research like this that can never be tested? Genuinely curious. Shouldn't we find non-Earth lifeforms FIRST before even trying to make these conclusions?

Edit: Wasn't trying to be harsh here. To be clear, I do believe in consciousness. This sounded a little clickbaity. I also think string theory is a meaningless pursuit.

String theory is in fact falsifiable contrary to popular belief. It's just not practically falsifiable with current (and likely future, for a while) technology as the energy scales we need to probe to falsify it are astronomically large.

The problem with assertions like this is there’s not an attempt to prove or disprove them. Just a vague reasoning from examples.

Science works. Philosophy can help guide that by helping us decide where to look. So I guess this paper is helping in its own small way.

by cadamsdotcom

6/14/2026 at 8:03:00 AM

Philosophy is often a key stepping stone to science. Wondering what could be, is taking someone to the next step. If we ever want to do something that isn't just small increments on the past this is needed.

Reading the paper, this seems kind of silly.

The argument essentially is. The universe is really big. It would be weird if we were the only thing alive in it, so probably there are other life forms out there. Given enough of them probably some are conscious and made out of different stuff then we are.

And sure, fair enough. That seems plausible. But it also seems like not a very interesting argument. It is essentially just saying the universe is big, therefore all the possibilities are out there.

Solaris ? Do stars dream of being a Sun and what they can do about it ? (master SF)

- consciousness? - yes, lots of it is there, as of many other beings caught by _Language Models_

Solaris asks way more questions than it answers. How does a planet evolve a sentient ocean? Did the ocean arrive from elsewhere to a dry planet? On what substrate would sentient oceand form and how would they reproduce?

by trick-or-treat

If forms could evolve (self or own factors), multiply it by infinity to find 1 at least (as we are) ?

Aside of a a joke that the universe (with us as a part of it) is not evolving but computing the number (42) - which eventually may become real thanks LLM.

by flanked-evergl

Good comment.

Life needs some kind of chemistry that doesn't lock up into compounds so stable they're hard to crack apart, but allows compounds stable enough to build structures. Carbon, hydrogen, oxygen, and nitrogen are suck a system. That's why organic chemistry is a thing. There aren't that many families of elements with that property. Ammonia and silicon based life have been suggested. But none of the alternatives have very promising chemistry. See [1]. Life is probably stuck with CHON, in the "goldilocks zone" where water exists as a liquid.

We now know that planets are not rare. Many extrasolar planets have been discovered. A few are promising. The systems with known extrasolar planets might have smaller, more interesting planets, too small to be detected at interstellar ranges.

But stars are a long way away. Unless FTL is possible (which it probably isn't, because causality would break), the most we can hope for is someone to talk to by radio or something similar.

See the Drake Equation.[2] There's been progress on firming up the numbers since the 1950s.

by Animats

6/14/2026 at 9:44:32 AM

CHON are also very common in the universe. Most proposed alternatives (not all) depend on things less common. This doesn't rule them out but it makes the odds worse.

Radio communications between tween solar systems require more energy than we have. We couldn't detect earth level civilizations in the nearest solar system (which probably doesn't have earth like life) even if both of us by chance aimed at each other at the correct time.

It can’t, unless you descend into sophistry. We came up with and defined the word “consciousness” specifically to fit our own understanding of the collection of behaviors we do that seem to apply only to us. What it means is based on what _we humans_ do, not something observed objectively, so it’s more like a human trait than a thing by itself that we fit into.
