Nearly every vital function of a cell can be taken out from a cell, and carried out in a 'cell free system'. ie: Everything required for life to occur, can be done on a simple chemical level. Every protein in a cell can be produced by taking out the DNA, adding the AA, the Polymerase, and the transcriptional activators. We can make the proteins without a cell from DNA. So DNA => proteins is entirely chemical.
Proteins carry out the enzymatic jobs while attached to matrices, catalysing stuff as it is washed over them...
Lipids form bilayers by their very nature.
Proteins take on conformational shapes (sometimes assisted by other proteins), and these shapes may bind to lipids and shape the lipids...
Everything that is required for life is a chemical reaction... Why would I think that there would be any reason for life to be anything else?
Materialist philosophers are biting at the bit wanting to put life on their list. Yet by claiming it, they violate the very standards of proof they say they live by.
Huh? How is claiming that life = Chemistry violating materialism?
If you read my response to FZ, you will see what part of the chemogenesis theory I don’t buy.
I will reply to that next.
But if it is chemistry alone which has achieved life, then I would be perfectly happy to accept that. But prove it first. My objection is that materialist/scientism devotees are not being objective; they are biased by their desire to prove their beliefs are correct, yet they claim they exemplify objectivity and the objective method! That denial of their bias is exactly what prevents them from noticing that the progressive organization associated with life is utterly beyond anything chemistry ever achieves on its own.
I will admit: It is part of being a materialist, or a pragmatist, or a realist etc, that we have assumed that what we see is what we get. That is the base assumption. I don't claim to be validating that assumption, proving it true, or finding evidence for it. It is an assumption. An assumption which produces many practical results, and so one I plan on sticking with.
Based on that assumption, all evidence thus far points to life = Chemistry.
I assume you are citing PCR as an example of chemical self organization. Really, however, it is highly manipulated by human consciousness as they denature the synthesized polynucleotide, control the temperature changes carefully, repeat it about 20 times, etc. True, you get it to replicate millions of times, but you are starting with the programming already in place (DNA), and through processes that were established by life in the first place. So this is a far cry from anything chemistry is capable of when left to its own devices.
You are exagerating way too much. Firstly, the DNA doesn't hold any programming with regards to the PCR. The DNA could be any code, it is irrelevant to the PCR process. All that matters is that you ahve a strand of DNA. Secondly, i don't think you can really say 'We denature the synthesised polynucleotides'...we set up a system which cycles through heating and cooling. Of course we do it knowingly, but we make the conditions right for the chemicals to do what they do.
I wasn't attempting to show PCR as an example of chemical self organisation, at least not in the 'look at what this does if left to its own devices' way. I did mean for it to be a demonstration of how chemistry has certain attributes, certain ways of behaving, which can give rise to some pretty interesting results. For example, since learning about PCR, it has always stuck in my mind the idea of an RNA molecule being on the eddy a current of hot water streaming out of a thermal vent at the bottom of the ocean. It is possible that that RNA molecule could be copied as nucleotides were added and removed in succesion as it cycled out into the cold water, then back into the hot water.
A crude idea, sure, but nonetheless, a completely natural environment in which chemicals could achieve a form of replication.
PS: RNA also makes tRNA (which translates the Genetic code (held in RNA) into proteins...) So this RNA molecule could do more than just copy itself...
Are you sure of your statement, “The God hypothesis has no backing at all except the claims of millions of people. . . .”? I followed that quote (above) with something you said earlier in this thread because I think you are doing exactly what you accuse creationists of doing.
First of all, you are assuming that only sense observation produces proof. For example, what if there are things which can only be proven to oneself, does that necessarily make them any less valuable or true? Can I prove to you I love my wife, especially when I am not in her presence? That proof cannot be externally demonstrated to others, but I know inside beyond doubt. Further, I don’t care whether you or anyone else knows or not . . . I am content with knowing it myself and so I would never undertake some sort of “objective” proof. And if I did know God, I would feel exactly the same way about it.
No I can't prove that you love your wife, but that doesn't affect my faith in my materialistic philosophy. As I said earlier, its a philosophical assumption which I believe to be valid, based on the consequences. I am in essence a pragmatist. The practical application of what I do is evidence enough for a continued practice. As for God though, no matter how personal someone feels they are with God, there is a truth about 'Gods' existence which is verifiable objectively. Either God exists, or that person is talking to themselves. There is simply no other options. Either way, there is a verifiable truth claim.
Are you so sure sense experience is the only reliable avenue to knowledge? It seems to me it is you who assumes that all truth that can be revealed will only be revealed through the objective, sense experience-dependent methods of empiricism. If so, then for you it will be “. . . easy to ignore arguments against something that you believe is irreproachable.”
I am a philosopher at heart. My philosophy of choice happens to be a materialistic one. At the base of all my claims though, is a primary choice to ask myself "What do I know without assumptions?" Most of the time, the answer is nothing. So I go to phase two. What do I have to work with then? Well...I have the way things seem to me. OK...lets work from that... and off it goes.
Nothing in my mind is irreproachable. I don't claim to have the truth. I only claim to work with what I have, and try to be honest with myself. i couldn't possibly allow myself to hold something which I know is probably wrong as irreproachable.
In the past I’ve challenged people here to study a certain class of subjective investigators . . . those known to have attained “enlightenment,” such as the Buddha or Jesus (i.e., I mean study the nature of the original experience, as opposed to relying on the utterances of the religious millennia later). There are thousands of such individuals who actually achieved something through turning inward. Now, if you choose not to develop your expertise about this consciousness potential, and then you say “The God hypothesis has no backing at all . . . ,” have you truly and objectively studied all the evidence before stating out of hand there’s nothing to it?
I haven't studied these guys, but at the same time I still feel no desire to because it si quite clear from history, from people around me, and from my own experiences, that the 'inner' is faliscious. A trick we play upon our selves. That is why we all end up with different answers: We are all different. With different experiences we play different tricks on ourselves, and we come to believe different things.
OK, I can't be certain of that, and one day I might look into it, but as the gambling man I may or may not be, I will place my bets on the more solid basis of our internal experiences... the real world. And play with that for a while, and see where that gets me.
I'll play with your other post later... This is getting too tiresome.
