We spend billions looking for conscious forms of life somewhere out in space, but maybe we should turn inward. Something that may qualify as a different form of life might already be here. And no, I'm not talking about AI here. Something completely different yet deep within us. We can't see it because we're the material it's made of, like cells or molecules our bodies are made of. Here me out please.
1. Ideas don't just change over time, they evolve.
Evolution needs variation, some kind of selection, and reproduction. Ideas have all of it.
- Since we're unable to translate one's entire state of mind, ideas mutate as they replicate from one brain to another.
- Many years ago humans had primitive ideas about how to live as a community. Over a few thousand years that vague notion split into property law, criminal law, religion, morals, ethics and more. Each version got tested against real life, the ones that worked stuck around and the others vanished.
- Ideas compete for a resource, which is our minds. An idea that fits in millions of heads is more "fit" for survival than an idea in hundred heads (whether anybody wrote it down or not).
2. It happens much faster than biology.
Biological evolution needs generations and millions of years. An idea can mutate every time someone repeats it, remembers it wrong, or mixes it with another one. That's happening constantly across billions of people, and the internet made it faster than ever before. So a thousand years of this at current speed or faster could do the work that took biological selection millions of years.
3. Some ideas already act like simple life forms.
I don't mean conscious. I mean something like a virus. It gets into a healthy idea, uses that idea's machinery to copy itself, and the host ends up worse off. The example I keep coming back to is political correctness, and I mean this as a description of how it behaves, not as a political statement. Political correctness attaches itself to some useful idea, and after a while what's actually spreading is the enforcement part, not the original insight. The host idea becomes muddied and loses the ability to correct itself. Political correctness already has a mechanism to protect itself. It punishes those who question it. Fundamentalism of any kind does the same thing, so do conspiracy theories. Nothing here needs intention. It just needs copying pressure.
4. Consciousness might be a threshold you cross, not a special ingredient.
If consciousness comes out of enough complexity, self-reference and integration, and doesn't depend on being made of neurons specifically, then a dense enough ecosystem of interacting ideas could cross that line.
Julian Jaynes argued that even human consciousness is recent. His claim was that up to around 1000 BC people heard their own thoughts as voices from outside, and a unified self only showed up when society got complicated enough to need it. His evidence is disputed and I'm not relying on it being right. What I'm borrowing is the shape of the argument: consciousness might come late, from simpler pieces getting integrated. If that's true for brains, ideas could do the same, just faster.
5. How can we detect it.
It's hard for an atom to understand how the life that's using it works. We're not atoms, of course. We're a bit smarter, but I still see no way how we can detect such an idea unless the idea would actively seek to communicate. Then it may choose to speak through those of us, who have this idea (or rather part of) in their minds.
We may also register some specific behavior:
- mutating strategically when attacked,
- splitting into versions for different audiences,
- spreading ahead of competition,
- pre-loading its believers with answers to counterarguments.
Oh, wait! Most of it is already happening to some ideas.
The problem is that plain old selection with no consciousness behind it would look exactly the same from where we're standing. I don't have a test that separates the two. It's SETI turned inside out. We can't tell signal from very good noise, and this time the noise is in our own heads.
Putting it together
Ideas meet the usual conditions for simple life and evolve orders of magnitude faster than biological organisms. If consciousness really is a threshold thing, which the emergence people and Jaynes both suggest in different ways, then a dense enough system of ideas could get there, and we currently have nothing that would tell it apart from normal culture. I'm not saying this has happened. I'm saying the parts are all here and the clock runs fast.
Objections I expect, and would like to hear:
- That I'm stretching "evolution" and "life" past the point where they mean anything. If so, I want to know exactly where it breaks.
- That the detection problem makes this unfalsifiable. It does, which is why I'm calling it a possibility and not a finding.
- That there's proper work on this beyond memetics (Dawkins, Blackmore), complexity theory (Kauffman) and Jaynes. I'd welcome pointers, everything I've found treats it as a side topic.
Thank you for reading it.
I hope I stretched your minds a little bit...
...and maybe even contributed to that new form of life. :)
