You misread - we understand the genes and gene products necessary and sufficient for life - it is literally just chemistry of well understood processes . There is no reason to invent the idea of a soul. Inert matter differs from life in that life has the necessary biochemical processes and mechanical structures to maintain those biochemical processes. This chemistry is the basis of ALL (known terrestrial) life (aliens might differ), from single cell to humans.
Science has not given us any experiment or evidence that the first principle of life resides in matter itself, or outlined a physical process which accounts for the entirety of life (particularly the will and intellect). We have
certainly seen that the will and intellect have physical manifestations in the brain, and can be influenced and disabled by manipulating the brain. This is not a physical explanation for the existence of these things; it simply confirms the thing that philosophers have been saying since Aristotle: the nature of a human soul is to be embodied.
I am sure that there are scientists, and more frequently the scientific-faithful, who make the claim that science has answered the questions of "what is life?", "what is the nature of the first principle of life?", "is the first principle of life material or immaterial?", "what is it 'to be'?", "what is the intellect?", "what is the will?", etc. But science has not answered these questions. If you believe it has, you are mistaken.
JoshuaD: The soul is providing animation and unity to the matter.
LetterRip: So chemistry is another name for soul?
This is a good question, and the answer is no. Like the heart or lungs, chemistry is a principle of life, but it is not the first principle of life.
Life must have a first principle (i.e. first cause). I do not mean historically (our parents are the first historical cause of our life). I mean that thing which sustains life moment to moment.
Following from Aristotle and his predecessors, I call that first principle of life "the soul". It's a label for a thing that reason tells us must exist. There must be a first principle -- an underlying root cause -- for life. Starting from this premise we can try to determine what the nature of the first principle is. The question we have focused on lately in this thread is: is the soul matter, or is it something else?
We can see that to be a living thing (or a principle of life) does not inhere in matter, because, if that were the case, all material things would be a living thing (or a principle of life). Therefore, we can see material things possess only the potentiality to be a living thing or a principle of life. In order for this potentiality for life to be actualized in matter some principle of life (for which life is inherent) must act upon the matter. This shows us that the soul (i.e. the first principle of life) is not matter, but rather something which actualizes the potential for life in matter. As an analogy, the soul is sort of like energy or heat;
it is not a substance, but rather something which actualizes a potentiality in matter.
LetterRip: If not, please feel free to inform me how the soul is interacting with the chemistry and providing something necessary for life that isn't provided by the chemistry. I'd be interested in how you discovered this. As far as I can tell it is purely a claim and arguement made from ignorance of chemistry.
My partner has a PHD in chemistry. She is amused by your assertion that chemists have somehow fully mapped life (including the intellect and will) and can fully explain it through chemistry. They have little disjointed insights in a great sea of unknown. They can describe some very small processes on a mechanical level. They are nowhere close to mapping the physical processes of life.
It doesn't matter, though. I am not making an argument from the gaps in our current scientific discoveries. I am making an argument based in reason, which is not contrary to the discoveries that we continue to make in science. I can't tell you how "the soul is interacting with chemistry" any more than you can tell me the answer to every scientific question I might ask. That's not the hurdle I have in showing you that we can see through reason that there must be a first cause of life, and that that cause is not material.
LetterRip: If not, please feel free to inform me how the soul is interacting with the chemistry and providing something necessary for life that isn't provided by the chemistry.
I have no idea how the intellect works or how the soul provides the power of the intellect. Through reason we can deduce that something non-corporeal must be the first principle of life
That is not a justifiable hurdle to require that I pass. The whole world is a mystery, even the physical world. We don't know how anything works past a certain point.
JoshuaD: Yes, you don't. I'm not blaming you for this. All of the education and all of the philosophy we were born into tells us that there is no need for metaphysics. It brushes the big, big problems with this view under the rug (like you did above) by saying lots of complex scientific words that don't actually respond to the questions of metaphysics.
LetterRip: I haven't been using complex words. We appear to making steady progress on every question of metaphysics. I went through an exhaustive list of things claimed to be in its perview and they are all things being addressed by modern science.
You have flooded the thread with links, as if a link is a substitute for a conversation. You have spent a ton of time talking about the minutia of scientific processes (such as your understanding of current state of genetic studies) which has no bearing on the points I have made.
I love science. It is so cool. And it has made our lives a lot better. I am not arguing 'in the cracks of science", as if my points are just one scientific discovery away from being negated. I am saying that we can see that the nature of certain questions about our experiences and
what it is to be are, by their nature, outside of the realm of science. You haven't responded to this point. Instead, you have effectively "hey check out this cool new science". Yes, they discover cool new science all the time. No, nothing you have linked to nor nothing they are discovering negates the things I have been speaking about.
JoshuaD: Think about history: how many generations do you believe lived with some foolish superstitions and ideas about truth? What are the odds that today, now, we are finally the people free of those things?
LetterRip: Ideas like the soul, our fates being guided by stars, beliefs in Gods, ghosts, demons and demonic possession, curses, etc. clearly still exist - so plenty of people still believe in foolish superstitions. We've found the underlying causes of phenomenon that those concepts were invented to explain - bizzare behavior isn't demonic possession - it is caused by abherrent processes in the brain that can be due to infection, toxic exposure, or trauma, or genetics. Deformed births aren't from being cursed or evil parents but abnormal fetal development that can arise from a variety of causes. Life is a result of chemical processes not a soul. Many of the things attributed to Gods and attempted to be predicted by astrology - plagues, crops destroyed by weather or insect infestations and other years having bumper crops - are fully explainable by understanding climate science and how they interact with insect life cycles. Strange sudden deaths aren't from curses but often from underlying defects in the heart, blood vessels, brain, etc. Impotency can't be cured by sympathetic magic (ie consuming 'medicines' made from 'long hard' objects like ground up rhino horn) but is due to underlying physiological and neurological issues and can be treated by addressing those issues.
I have not mentioned the stars, ghosts, demons, possession, curses, evil parents, astrology, sympathetic magic, or anything else like that. I have talked about philosophy, metaphysics, and the thoughts of some philosophers -- primarily Aristotle and Aquinas -- on these topics.
Who are you talking to with this post? What does this paragraph have to do with anything we've said here this past week? Are you here, having this conversation with me? I am not "every person you have ever spoken to who disagrees with you". I am me. My name is Josh. I am making arguments I find compelling. If you'd like to talk to me, then great. Talk to me. Take the time to comprehend what I've written and then tell me what you think of it. I'll do the same, and maybe we'll be better for the exchange. I haven't once saddled you with any of the things other people have said to me. I would appreciate the same courtesy.
JoshuaD: But we have minds as well, and our minds are in contact with something that transcends matter.
LetterRip: There is no evidence of this, and plenty of evidence this isn't the case.
Yes we do see it, we see it in our will and in our intellect. We see it in the existence of moral truths. We see it in our ability to perceive those moral truths as abstract ideas. We see it through reason, not through faith. Aristotle outlined the existence of these things (rightly or wrongly) through reason. He was not a religious man.
JoshuaD: We see [something that can not be accounted for through matter alone] in our free will.
LetterRip: It isn't even clear that we have free will in the way the word has been used throughout history. We can be 'puppeted' by electrical stimulation and will have the full belief that that puppeted action was the result of free will even though it was completely induced without our choice. We are investigating the concept of free will, but it certainly doesn't imply a soul.
This is the sleight of hand materialists do. Your metaphysics can give
absolutely no good account of free will, and so you kind-of-sort-of deny its existence, despite the fact that its existence is like, one of the most immediate and obvious truths we all experience every moment of every day.
You deny the thing exists, you point at some narrow insights we have had into some of the physical manifestations of the thing, and then you essentially say "I have some faith that science will be able to fully explain it one day".
This is not a response. It's a dodge.
LetterRip: [Your belief that our minds are in contact with something that transcends matter] is purely an article of faith on your part.
Aristotle was not a religious man. He was a philosopher. Through philosophy -- through reason --
he saw that the soul existed and was able to distinguish some of its properties and powers. This is not a belief rooted in faith. It is a belief rooted in reason.
JoshuaD: We see it in the immediate experience of reality that we have (which science has absolutely no explanation for).
LetterRip: I'm not sure what you are saying by this or what you think 'science has absolutely no experience for'.
Consciousness, free will, and intellect.
JoshuaD: We see it in our ability to perceive and comprehend the transcendent ideas, like justice and beauty.
LetterRip: Beauty appears to be evolved for identifying reproductive and environmental factors that contribute to survival. Facial symmetry, skin smoothness, hair shininess are good indicators of health.https://en.wikipedia.org/wiki/Evolutionary_aesthetics
Justice appears to be evolved from factors that relate to survival in groups and empathy. These are capacities shared by other animals. https://www.psychologytoday.com/us/blog/animal-emotions/200906/wild-justice-and-moral-intelligence-in-animals
Yes, animals are able to perceive, in a limited way, the moral reality. They can see the consequences of action and have some sense of the benefits of community and cooperation. They possess these things instinctively or as part of their estimative power. They do not and cannot comprehend justice or beauty abstractly like you and I can. They can only comprehend it concretely.
JoshuaD: I program computers and I've kept up on machine learning. I am not an expert, but I have more than a layman's familiarity. I am correct in characterizing them as clever machines. They are not intelligent like we are. They are very subtle machines. No one who builds these systems suggests otherwise.
LetterRip: I build these machines (though haven't done much of that lately, and not in a professional capacity) and have a background in neuropsychology. They are indeed 'clever machines' - but then all animals are also. Something like "GPT-3" is in fact 'intelligent like we are' in many respects. It is arguably an AGI, though not a very 'bright' AGI. https://towardsdatascience.com/gpt-3-the-first-artificial-general-intelligence-b8d9b38557a1
1. Good, we agree. You were very disagreeable about it, but ultimately you agreed with me that the machine learning systems we have today are not artificial life.
2.
Again, I do not say that we are incapable of making a living thing. We make children all the time. Humans have the power to beget other living things, and we may very well have the power to create living things. As I have been saying for pages now, this is not some problem for me.
3. GPT-3 seems cool. It doesn't look like a living thing to me and instead looks like a really cool tool, but see #2. It doesn't matter at all to my arguments one way or the other.
LetterRip: I'm unclear why you seem to think that 'qualia' are unexplained and inexplicable by science. See this discussion: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3957492/
Yes. Since page one of this thread I have acknowledged that there are materialist philosophies and philosophers. I have spent four pages attempting to illustrate the reasons why I do not find their arguments convincing. If you would like to read your link and then make your arguments as to how exactly you imagine a materialist metaphysics can make sense of consciousness, the intellect, or will, then please do that. I'm not going to do your homework for you, and I'm not interested in having a conversation with a person who doesn't say his own words or his own ideas. I could have linked you to Aristotle's book on page one of the thread and said "this is wrong, see this book". Would that have been a conversation or at all useful? Of course not. I'm here to have a conversation, not to swap links.
You talk like Trump - your personal lack of knowledge you attribute to everyone 'noone knew that healthcare was so complicated'.
I have been insulted several times in this thread, by you and by others. If you'd like to have a conversation with me, don't speak to me that way please. If you do it again, you and I will have to stop having a conversation with one another on this topic.
