Although the nuances of the debate are interesting, I'm always a little disappointed when hackers and scientists lean towards physicalism. If you are of an analytical mindset, it's tempting to be drawn to explainable phenomena and to reject pie-in-the-sky and intractable philosophical questions.
I think that just displays a disappointing lack of imagination, a fear of the unknowable, or both. That's why I had to opt for the neglected third-option.
I just don't feel like we have sufficiently solid axioms to even approach such a question with any reasonable degree of certainty. Physicalism vs Dualism, for instance, hinges on the definition of physical, which might be conveniently defined as phenomena within the current physical subsystems we are aware of. In that case, what is defined as Dualism today could become Physicalism tomorrow as physics evolves. Or indeed, there may be dimensions of reality that are incomprehensible by us consciously due to the very nature of our meat brains, but which nevertheless we have some connection and effect on our brains but which will never be comprehensible due to limitations of our reasoning which has evolved under the constraints of meatspace. The idea that predictable behavior implies determinism will never be credible in my mind because we will never be able to observe anywhere near enough of the universe and crunch all the numbers to be sure that there aren't unobservable inputs that we've missed. There is no microscope or telescope powerful enough.

That's odd, I'm always disappointed when hackers or scientists lean towards an esoteric view of consciousness, mainly because we should be supremely well suited to realize that the mind is not a concept that somehow requires supernatural augmentation to be feasible. Dealing with both information processing and the nature of reality every day, I feel there is really no excuse for hackers and scientists to evoke the metaphysical. I also think postulating a supernatural component to consciousness prevents an observer from really noticing the phenomenal beauty of the natural processes involved.

See, that right there betrays a misunderstanding of my entire point.
Why must we be only focused on what is required for something to exist? Why the obsession with cause and effect at all levels? I agree this stuff is fascinating, fun, and an epic quest unto itself. But if you try to invoke Occam's Razor after your girlfriend dumps you, you're going to be as clueless Eisenberg's fictional Zuckerberg was in that situation.
To distill all the nuance, joy and sorrow of the human experience into that which can be analyzed, measured, quantified and recorded in a canonical model is a sad existence. It is as if you are content to never taste fresh fruit because frozen fruit contains all the same constituents.
> Why must we be only focused on what is required for something to exist?
I believe it's important to distinguish between a scientific world view and a spiritual one. In the world of science and curiosity, we always ask why something is the way it is. Looking at the requirements for a phenomenon can be a tool in this process, but it's not the only one. In this scientific world, separating and understanding cause and effect is extremely important, it's part of the mission. You call it obsession, and maybe that's a fair charge, but it's really one of the things necessary for constructing scientifically meaningful models.
> But to distill all the nuance, joy and sorrow of the human experience into that which can be analyzed, measured, quantified and recorded in a canonical model is a sad existence.
Please realize that not all of us think this way. For some of us, making stuff up because it somehow resonates with our hearts is the definition of a sad existence. Some of us want to analyze, measure and quantify the universe simply because it is vast and awesome, and revealing the underlying mechanisms of it is extremely rewarding.
On a personal note, I believe that religious and supernatural world views cheapen much of the nuance, joy and sorrow of the human experience. And yes, we all feel those things, and they're not a religious experience. We're scientists, not robotic kitchen appliances.
> I believe it's important to distinguish between a scientific world view and a spiritual one.
Why?
> In the world of science and curiosity, we always ask why something is the way it is.
So the spritual world is not curious? What about when you ask yourself why the universe exists? Do you then stick your fingers in your ears and chant lalala because it is a scientifically intractable question?
> In this scientific world, separating and understanding cause and effect is extremely important, it's part of the mission. You call it obsession
Yes, but let me state unequivocally that you do not need to define yourself by science in order to perform science with integrity. Such thinking is actually a form of faith: that science is the only source of meaning.
> Please realize that not all of us think this way.
Yes, I was just stating my opinion. It was clear that you do not think this way. However I believe you are a critical thinker and that I may at least get you to appreciate why I would see things that way.
> For some of us, making stuff up because it somehow resonates with our hearts is the definition of a sad existence.
You're using "making stuff up" in a subtly pejorative way here, but everyone makes stuff up. Making stuff up is also part and parcel of science. In fact it is the essence of sentience. Resonating with your heart is an orthogonal issue which applies equally well to science or philosophical endeavours; we can all be trapped or misled by it. But the material difference between philosophy and science is that science is only concerned with testable hypotheses. But are testable hypotheses the only important things in life?
> Some of us want to analyze, measure and quantify the universe simply because it is vast and awesome, and revealing the underlying mechanisms of it is extremely rewarding.
I agree, which I alluded to in my previous reply.
> I believe that religious and supernatural world views cheapen much of the nuance, joy and sorrow of the human experience.
Sure, but so too does pseudo-science cheapen science, or inferior ideas cheapen great ideas. Don't use religious nuts as a strawman to justify an atheistic hubris that nothing exists beyond what our physical instruments are capable of revealing.
In closing, let me state that I don't hold onto any particular belief and use it as a shield against evidence and reason; as no doubt you have witnessed among a certain type of faithful individual and which has shaped your opinion of "the spiritual world". Instead I just take the nature of my own consciousness as evidence that there is something bigger going on here than we can be aware of from within our meatsacks. This is undeniably a form of faith, because of course there is no firm evidence for such a broad claim; but neither is there evidence against it, and it does not make me hostile to any form of observation and deduction that science can provide us.

Until anyone can actually articulate what they mean when they talk about "the spiritual world", I've personally given up on spending any time discussing it.
No, it's not, by definition. Instead of finding out how stuff works, this particular philosophy prescribes just deciding how it should work and then believing this arbitrary decision to accurately reflect the nature of the universe.
> What about when you ask yourself why the universe exists?
Yes, I do, but I suspect that it's a different "why". Mine is causal, where I suspect yours is centered on some definition of cosmic meaning. The problem I have with this view is that it seems inappropriate to me. It's inappropriate to tag cosmic processes with a concept that should be reserved for intelligent life forms.
> However I believe you are a critical thinker and that I may at least get you to appreciate why I would see things that way.
I do, I'm sorry if I seemed overly aggressive. I'm just so used to religious people demanding scientific recognition of their views that I sometimes overshoot my target. However I have to admit that I sometimes feel deeply sad and disappointed.
> Making stuff up is also part and parcel of science. In fact it is the essence of sentience.
It's this fallacy which brought us a movement that explores "alternate theories" in biology class. Religion is not science. "Making stuff up" that is unsupportable by evidence is not science. I agree that making mental models is the essence of sentience, however it's not required that these models are unprovable and in contradiction of the laws of nature.
> But are testable hypotheses the only important things in life?
I believe when it comes to very important things, like the nature of reality for example, making testable hypotheses the basis of a person's mental models is the only important thing. Rejecting the whole stack of evidence and the hypotheses that came out of those observations in favor of something untestable and arbitrary does not seem like a viable strategy to understand the nature of the universe. In this context I need also to point out that there are important things in life that pertain to your personal life itself, not the universe. I'm just against mixing them up.
> Don't use religious nuts as a strawman to justify an atheistic hubris that nothing exists beyond what our physical instruments are capable of revealing.
It's not just about religious nuts, it's about a fundamental difference in perceiving the world. You call it atheistic hubris, I call it the growing impatience of rational people in the face of a world governed by fairy tales. When a fairy tale crosses the boundary from personal phantasy into a widespread public substitution for the provable truth, it becomes a lie designed to manipulate people. And I don't mean to imply that you hold this position, I merely want to explain why I feel so passionately about the issue.
> I just take the nature of my own consciousness as evidence that there is something bigger going on here than we can be aware of from within our meatsacks.
I know, this is where our fundamental disagreement comes from. I studied the sciences, I studied the human body, and I like to think that I thoroughly enjoy the very fact of our existence. I don't think our meatsacks are profane puppets in the service of an unseen force that floods the universe with artificial meaning. Instead I believe our "meatsacks" are marvelous, awesome machines and they gave rise to a form of consciousness that is unparalleled on this planet. Those meatsacks are the substrate, the hardware our consciousness runs on, and they're doing a pretty good job of it.
> "The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function."
For me, the supernatural is not a valid idea to begin with. I don't have to believe in any and every idea out there, I don't have to give them all equal weight. Nobody does that, even spiritual people don't do that.
> No, it's not, by definition. Instead of finding out how stuff works, this particular philosophy prescribes just deciding how it should work and then believing this arbitrary decision to accurately reflect the nature of the universe.
Okay, this is actually just you projecting your beliefs onto what spirituality means. It is not by definition in any sense of the word.
> It's inappropriate to tag cosmic processes with a concept that should be reserved for intelligent life forms.
How do you know the universe is not an intelligent life form?
> It's this fallacy which brought us a movement that explores "alternate theories" in biology class. Religion is not science. "Making stuff up" that is unsupportable by evidence is not science.
Sigh When did I say it was? I explained clearly the difference between science and other forms of making stuff up, and you talked right past it. It is as if you believe human beings are incapable of thinking in both scientific and unscientific ways.
> Rejecting the whole stack of evidence and the hypotheses that came out of those observations in favor of something untestable and arbitrary does not seem like a viable strategy to understand the nature of the universe.
Who's rejecting anything? Science does not tell us whether there is a god or not.
> You call it atheistic hubris, I call it the growing impatience of rational people in the face of a world governed by fairy tales.
That's not what I call atheistic hubris. What I call atheistic hubris is that the lack of recognizable evidence of higher consciousness is evidence that there is no higher consciousness. The reason it is so hubristic is because we no idea what said evidence would look like. Declaring this one way or the other is not scientific, it is instead I believe, a psychological need to have a firm order in one's knowledge of the universe. I stand as evidence that this is not a pre-requisite for a true and healthy relationship with science.
> I don't think our meatsacks are profane puppets in the service of an unseen force that floods the universe with artificial meaning. Instead I believe our "meatsacks" are marvelous, awesome machines and they gave rise to a form of consciousness that is unparalleled on this planet.
Why do you say puppet? Trying to pigeonhole spiritual belief into some kind of biblical metaphor is exactly the attitude I'm fighting against. I'm not saying that your mind is not governed by chemical processes playing themselves out; I'm saying that even if that's 100% true (which is a very difficult truth to verify when you get down to the nuances), it doesn't mean there isn't something else going on on another level. Perhaps the universe is conscious and you are just one small part of that, or perhaps there are parallel dimensions that get the information from our universe in some read-only fashion. My point is not to arrive at the objective truth (how often do you arrive an objective unchanging truth in your interpersonal life?), but rather to leave myself open to bigger questions even if they remain unanswerable in any scientific capacity for the rest of time.
I think that just displays a disappointing lack of imagination, a fear of the unknowable, or both. That's why I had to opt for the neglected third-option.
