I would ask exchemist to clarify where the misrepresentation occurred, but unfortunately, as others, he has withdrawn from the discussion. Asking would be a waste of time. After 12 pages, you should realize that nobody cares. I have watched members in the religion forum abuse every idea that is presented in this religion section, whether it is good or bad -- for years. They pretend interest, then gradually change the conversation to be about science, then ridicule anyone who does not agree with them. This thread was never about abiogenesis -- it is about the "God" concept, which none of the members study or understand. The members here are reasonably intelligent and capable of reading and following a thought process, so this is a bait and switch tactic. Entertainment for the forum members. Normally I would not even respond to a thread in this forum, but when you noted that there is a difference between the spiritual and religion, and you made that comment without regard to any religion or practice, I thought that you might be worth talking to. On 1/29/2025 at 8:09 AM, Luc Turpin said: Additionally, my statement that 'although there is strong evidence suggesting life could have originated from simple molecules under specific conditions, it remains a plausible concept rather than an established fact' more accurately reflects the current state of scientific understanding, as opposed to claiming that 'abiogenesis is an objective fact.'" If you google abiogenesis, you are informed that the Oxford dictionary calls abiogenesis a theory. On 1/29/2025 at 8:09 AM, Luc Turpin said: Science can study the mental indirectly, but not directly. Science can study it, but they don't. They study the brain, or they study behavior, or they study societies. They do not study the mental and barely study consciousness. I have been studying consciousness off and on for decades and have come to the conclusion that some aspects of consciousness can interact with the physical. Some aspects of consciousness may actually be physical. I have asked members in other forums if they can tell me the properties of mental aspects, and they have no answer. Some aspects of the mental do have properties. But I must tell you that I have been fighting MS (multiple sclerosis), which slows me down, for about 50 years, and now I have cancer to fight also. I start my radiation treatment next week, which I have been told will make me even more tired, so I have no desire to provide entertainment for the masses. I sent you a PM with my email address so that we could continue this conversation if you are interested. I doubt that I will respond to many more posts in this thread. It is just too hard and serves no purpose. Gee

Life emerging from pure energy, which we have no real examples, evidence, or models for. Option 2. life emerging spiritually, which we would define as "super natural" again we have no real examples or evidence for. Both these examples extend our current definition of life outside of what would be considered mainstream. If you want to propose an alternative to life as we know it (matter based), then by all means crack on.

Yes. One could make that argument.

Congratulations. You finally got off the Science v Religion merry-go-round long enough to think. Think about this: Spinoza lived hundreds of years ago, so what has science learned in the meantime that would support or detract from Spinoza's work? Einstein used math to make his conclusions. Quantum theories and holographic theories built on his original ideas. 2 hours ago, exchemist said: Of course this conception of god is far removed from the personal God of the Abrahamic religions. So is there a personal "God" concept and a universal "God" concept? Two of them? Look to psychology for an answer to the personal "God". Jung taught us about the "God" archetypes, Blanco taught us about the logic in the unconscious by explaining that emotion ignores time, psychology tells us a lot about the personal "God". 2 hours ago, exchemist said: It is just an orderly principle of nature itself.

The interesting part is that the words are always used by "science" people. It’s because the science people are responding, as in “what you propose is magic”and how many instances are tied to a negation (e.g. “not magic”)? I don’t see what all is so interesting about that. It’s like going into a crackpot’s thread and finding that only the science folks are saying “perpetual motion” because crackpots know to avoid the phrase. But it’s perfectly legit to say perpetual motion violates the second law of thermodynamics. 10 hours ago, Gees said: So I guess the only options here are to conclude that religious people think "God" started life and the science people think that magic started life? It is no wonder that Luc and I are having trouble in this thread, as we don't think either of those things happened.

Gee I’m starting to feel that some of this is becoming futile, both for myself and for those responding to my posts. Being freed from religion while retaining one’s spirituality is truly a state of bliss. Catching someone on technicalities seems to be a common tactic in these forums. I completely agree. After studying consciousness for some time, I’ve come to wonder: does the mind emerge from the brain, or does it flow through it? I’m genuinely sorry to hear about your situation. I truly hope things improve for you as much as they can. Let’s take this conversation offline. 12 hours ago, zapatos said: What in the fuck are you talking about? Look up the definition of 'life'. Any version of the definition you wish to use does not include the possibility that life can exist without matter. I cannot believe you are this clueless. Go peddle your shit elsewhere.

CharonY Posted yesterday at 04:22 PM Posted yesterday at 04:22 PM 19 hours ago, exchemist said: Agreed on the second part of course. Regarding the first, even if abstract physics were to come up with some new principle that could be shown to play a role, that would still be a natural principle, not a supernatural one. As such it would be a part of a model of abiogenesis, rather than anything beyond it. Most likely. It could veer a bit into semantics here. I think the most general definition is that abiogenesis assumes life is originating from non-living matter. So the only way would be for biological matter to arise while skipping non-biological matter. This, of course is not really plausible, though the other part of semantics if of course defining what is precisely living vs non-living matter, where the borderline is probably a little bit fluid (as in most things biological, and mimics the delineation between chemistry and biology). Much of the attention has shifted towards replicating polymers and related activities, for example.

While you and the other moderators have the authority to shut it down, I believe doing so would be regrettable.

Isn’t science about forming hypotheses and testing them through falsification? Why should this principle not apply to abiogenesis? Aren’t there competing theories and viewpoints within science? To clarify, I’m not proposing alternative theories. My point is simply that claiming life arose from molecules in a primordial soup is both premature and overly simplistic. I also believe science has become so closely tied to this explanation—and similar ones—that it has somewhat neglected its responsibility to explore all viable possibilities. That is the crux of my argument. When I mentioned quantum biology and the holographic principle, my intention was to highlight that they are significantly different perspectives on the issue, not to advocate for them. Yet, I was asked to defend these ideas. The same applies to information theory, which offers a unique angle on abiogenesis. When I suggested that life might align with matter rather than arise from it, my goal was to present other potential alternatives—not to argue that life exists without matter. Before claiming that I’m contradicting myself based on the previous paragraph, I should clarify that I nearly had to invent a possible link to abiogenesis to include them in the discussion, not that they are actually being taken seriously by science.

I generally think of matter as distinct from radiation, but I suppose as a real physicist you will tell me both are in the end excitations of fields, so there is no substantive difference. As for conservation of energy, it's true that can only be spoken of relation to a physical system of some kind, whether it consists of fields, radiation or matter (in my narrower usage of these terms).
