AtlLiberal says: I'd like someone to explain how awareness begins at conception. That's baseless without believing in magical thinking. Without a nervous system developed to a certain degree I'd conjecture that there can be no "awareness". If they mean human awareness then they are deluded. If they mean awareness in the sense of a cell reacting to the conditions of its environment then I could buy that. That's why the meaning of words do make a difference. Awareness implies a certain degree of consciousness. I'd state that a cell or a group of cells is without this quality. We don't talk about hydrogen and oxygen "knowing" that their combination in the correct ratios produces water. It is a chemical reaction. The same with a zygote reacting to its environment. It is simply a reaction. IMO, awareness is not the correct term to use since it implies a consciousness. And that plays right into the hands of the theist with their magical soul. I think (as in opinion), that if you can poke it and it reacts, it's aware. Some people say that 97% of the multiverse is unknown to us because we can't sense it and we haven't yet built machines that can. So. We are surrounded by mystery. Figuring out what "consciousness" is and when it is present seems to fall into that mysterious category. Logic does not always work, at least not for me. There is a fine line there. I can well understand an organism reacting to its environment or altering its actions based on its interaction with said environment and I can also see something like a cell or atom appearing to do the same, but in reality simply following basic laws of physics. Some viruses form cysts in order to hibernate until conditions are better suited for them, but it is a fairly well understood process based on simple chemistry and not based on the virus making an informed and aware-like choice. People that base their beliefs on mysticism, the supernatural, or blind faith like to blur that line of awareness and reaction into a smear of indistinctness because that serves... @AtlLib That's why the meaning of words do make a difference. Awareness implies a certain degree of consciousness. I'd state that a cell or a group of cells is without this quality.I would love to agree with you on this because it makes sense. But is it true? (We must be careful.) Notice the assumptions you are making without proof. You have no actual knowledge that "a cell or a group of cells is without this quality." Each cell could in fact have awareness! Until you can prove that individual or group cells do not have awareness, you are making an unwarranted assumption. (We as humans consist of a group of cells, and yet we have awareness.) And so even though I would p... Also, using hypotheses in arguments to replace facts is a dangerous ploy to take. And as OC pointed out, argument from ignorance is never a good choice. And an organism reacting to its environment is often interpreted by us as acting with a purpose but this is merely our anthropomorphizing what we observe. It has been speculated that as a survival tool we view the world based on cause/effect This is whether or not such a condition exists. A clump of cells attaching to a uterine wall has not developed any neural pathways whatsoever, not to even say a self recognizing brain. Therefore it is unable to be conscious. Consciousness requires a means by which sensory input can be recognized. And ... Also, using hypotheses in arguments to replace facts is a dangerous ploy to take.Exactly right. That's why your statement: "I'd state that a cell or a group of cells is without this quality." ...is doing precisely what you already agree is dangerous ploy to take. @AcesLucky You slipped in your comment while I was typing Sorry. I'll have to say I don't agree with some of what you argued. Until you can prove that individual or group cells do not have awareness, you are making an unwarranted assumption.I hold the view that to be aware in the sense of being conscious requires a quite advanced neural system which usually requires a brain. (We as humans consist of a group of cells, and yet we have awareness.)True. Yet if we eliminate the group of cells we call the brain we have no awareness. You have no actual knowledge that "a cell or a group of cells is without this quality." Each cell could in fact have awa... @ AtlLib You stated: Therefore it is unable to be conscious.I stated: You have no actual knowledge that "a cell or a group of cells is without this quality." Each cell could in fact have awareness! You said: Oooops! This seems to be to be an argument from ignorance. You're asking me to prove a negative. Show evidence that a group of cells acts with conscientiousness without input from a neural system and I'll be swayed.Nope. I didn't say "Each cell HAS awareness!" but rather each cell COULD have awareness. I am openly admitting my ignorance by stating "I don't know... it COULD or it couldn't." Therefore I must not assume either! What I a... cont.. mcsmithblack alluded to our own doors to the outside world, our senses and sensing machines, being limited to the scope of our senses. And I would agree. If none of us had sight, could color be "sensed" by sound or touch or taste or smell? Color would be a whole range of information unavailable to us. But how would we ever know there is such a thing as color except by interpreting data from the other four senses? It would in fact be another dimension of awareness that we may never know is there. But yet color most certainly IS there. But does the external world of color go away simply because we have no awareness of it? In this sense mcsmithblack has a valid point. And so there ma... Just a little pedantic point Aces, but.. But does the external world of color go away simply because we have no awareness of it? If there is no being/creature with sight then colour does stop existing. Various frequencies of electromagnetic waves will still exist, but colour is a perception not a physical thing. Just as when a tree falls in the forest and there is nothing around to hear it, it does not make a sound, it creates compression waves in the air, which would be perceived as sound to any creature with the right sense organs and grey matter. sorry posted the wrong version of my comment. It should read Just a little pedantic point Aces, but.. But does the external world of color go away simply because we have no awareness of it?If there is no being/creature with sight then colour does stop existing. Electromagnetic waves with various frequencies will still exist. But colour is a perception not a physical thing. In red light the colour blue does not exist. It is not that blue looks black in red light, it IS black (i.e reflecting no light). Just as when a tree falls in the forest and there is nothing around to hear it, it does not make a sound. It creates compression waves in the air, which would be perceived as ... Examine the plant worldI think you've just hit on what I was saying earlier about our anthropomorphizing non-human entities. As you put it, "they certainly appear to be aware". You further state they they don't seem to have a CNS. Actually, as a former biology major, I can state pretty definitively that plants indeed do not posses a CNS. We must not fall into the trap of making assumptions on what seems to be "intention" when what we're actually observing is simply reaction. Without a brain, there is no consciousness as the brain is the seat of consciousness. No brain = no memory. No brain = no ability to imagine a future.... Nope. I didn't say "Each cell HAS awareness!" but rather each cell
Just to further address what you said earlie... @ JW If there is no being/creature with sight then colour does stop existing.Color stays. Only the label goes away. Various frequencies of electromagnetic waves will still exist, but colour is a perception not a physical thing.Hmm. That'd be like saying heat is not a physical thing. But no matter. My question is "will we have access to that perception" by way of hearing, taste, sound, or touch? If not, then we may not even know such a thing exists (because of our inability to perceive it). We may not see a bullet coming, but it will have lasting effects if it strikes us. Our inability to perceive it doesn't make it stop existing. @ AtlLib Actually, as a former biology major, I can state pretty definitively that plants indeed do not posses a CNS.And yet they rapidly change in ways that augment their "own" survival. A pencil, for example, also made of cells, does not. What properties exist in the tree that makes it grow and adapt to environmental changes "to survive" that does not exist in a pencil made of the same wood? Is it not in fact reaction to stimuli as mcsmithblack suggested? If a CNS is not necessary for reaction to stimuli why must it be necessary for awareness? I might be wrong in my definition, but if a thing is aware it is necessarily alive. (It may NOT follow that if a thing is al... You both are showing why the question of awareness itself is such a hotly debated thing. I thank you both for some very insightful points. Is it not in fact reaction to stimuli as mcsmithblack suggested?Naturally. If a CNS is not necessary for reaction to stimuli why must it be necessary for awareness?Define what you mean by awareness. This is the problem. It seems to me that you're implying consciousness when you use the word awareness. In a loose sense a plant is "aware" but not in the same way that organisms that possess a CNS. If by awareness you mean the plants ability to primitively react to stimuli than that is true. But it is not the same as an organism that is exposed to a threat and reacts. A tree does not descriminate when it encounters "threats". It is a simple reaction. There i... You both are showing why the question of awareness itself is such aI agree and welcome the chance to debate this issue. I wish I was more articulate. Thanks Aces! You've posed some interesting points. It is an important issue because it is connected to many social issues that are debated today. Stem cell research, abortion, euthanasia to name a few. Cont. It fails to do so and it dies and thus is unable to pass on its genetic material. There is no volition involved. It is not "protecting" itself in the same sense that we protect ourselves. @AtlLib It seems to me that you're implying consciousness when you use the word awareness.You may have a defining point. Awareness, to me, is the broader term in that we may be aware of something but not necessarily conscious of it. I've been speaking in terms of awareness, (so, "yes" to answer your question directly), by the organism "as" consciousness because it never mattered to me if said awareness was conscious or unconscious. And, to me it doesn't matter if the awareness is conscious or unconscious because if the organism can react to external stimuli for its own "benefit" it is necessarily aware of itself "in relationship" to that which is not itself. (Take a qui... Great article. Thanks for sharing. Why would it care about danger (let alone to another plant) if it had no sense of self awareness?That's the point! It doesn't "care" nor does it posses a sense of self awareness except on the biological level when it issues, as the article points out "cues" (I'm assuming some sort of chemical interaction since they covered some plants with plastic baqs and no "communication" occurred). And since the volatile cues affected genetically identical plants more strongly could easily be explained by the ways that the clones could better make use of the triggers. When they use terms like self-recognition they're referring to having the same dna ... @AtlLib It's biochemistry, not social interaction.I want to agree, but... "What we interpret as action in a plant is merely reaction to stimuli that the plant developed in its evolution that enabled it to survive."I'm just not sure how you can make such an unequivocal conclusion without applying it to all living things. But let's go ahead and assume that its true. (I'm a determinist, a physicalist really, as you are a materialist.) The fact of a central nervous system doesn't change that we also merely react to external stimuli developed via evolution that enabled us to survive. Therefore (and here's my point)... Let me try to be specific. Suppose for t... The fact of a central nervous system doesn't change that we also merelySort of. While it's true that we react to external stimuli this is not the only cues we look at when interacting with the world. Since we have a brain which stores memories, is capable of imagination and is able to postulate future actions and speculate on their effect we are not limited to simply reacting in a predetermined way, the way plants do. Let me try to be specific. Suppose for the sake of argument that plants really are not just aware, but conscious! How would we know... since their awareness is 'no... Believe me I certainly understand your point. I don't even disagree with it, really. What I'm afraid of is our lack of sense for anything but the ones we "share". And that leaves us open to mistake. Perhaps my empathy goes too far. Just as an aside: what would plants (or anything else) have to do before it could be definitively shown to be: a.) conscious, or b.) unconscious? (I'm thinking of a Venus Fly Trap right now.) Is it that ability to imagine the future? What is doing the imagining if its something "other than" chemical reactions in an organ? And if it's nothing more than chemical reactions in an organ, what separates our "being" from that of a plant? AtlLib, it's not that I... Perhaps my empathy goes too far.I think the only way that could ever be a problem is if it begins to interfere with your judgment. IMO we often cause problems not with the overabundance of empathy but with the lack of it. Just as an aside: what would plants (or anything else) have to do (I'm thinking of a Venus Fly Trap right now.)Or the mimosa tree which folds its leaves when stroked. This is a sticky problem because from infancy we've been told stories about many actions we observe in the world to be the result of a consciousness. Think of all the fairy tales w... Other species have been shown to posses a form of consciousness. And right now, it all seems to hinge on where they fall on the evolutionary bush. Perhaps, if we don't destroy the planet, other species may develop this capability. And no, I don't consider us to be superior (as in the theistic notion of having dominion over "lessor" species) to other forms of life but rather to be connected in profound ways. In many respects it could be argued that our development of consciousness may just be our undoing. I just ran across this article that is somewhat related to our discussion (very loosely). It has to do with protein organization within cells and a new technology o observe it. Rather geeky reading but it seems to illustrate the wonderful complexity that is achieved through chemical means. From the article: “Two cells which are biochemically identical can have very different behaviors, depending upon their spatial organization. With new technologies such as PALM, we are able to see exactly how cells are organized and relate spatial organization with biological function.” Deep, ain't it? I find stem cells fascinating too. Self organization seems to be a driving factor, an engine, of evolution. But where consciousness (or better still -- self consciousness) enters in, continues to be a mystery. To me, what tips the scales even with regard to self consciousness, is the want to survive! This appears to be far more than a chemical reaction. In it, is also contained the want ... I'm not after being right, I'm after the truth. And on this, I don't really know.And that's the beauty of living in reality. It's that region of not knowing that's the driving force that propels us into the future. The dominance of religion and superstition, otherwise known as the Dark Ages, was a period of certitude in solutions to difficult problems but very little progress towards actually finding out the answers. As far as quantifying mental constructs such as love, jealousy, hate, etc, the problem is complex only because the organ of thought is immensely complex. But we've only begun to seriously investigate this. It was just yesterday that we adhered to the concept of... With reference the Venus fly trap and the Mimosa tree - The trap and folding are reactions to stimuli when the plants are touched. There is no conscious thought, only a reactive response. If the plants were conscious wouldn't they be able to determine situations in which they would not waste the energy to close or fold? The Venus fly trap would only clamp down when it knew there was food and the tree would only fold if it recognized something that planned to eat its leaves? Just a thought. Another example would be the fly trap choosing NOT to close upon an insect because it was aware that it was full or the nutrients were unneeded and the tree might choose to allow some leaves to be eaten because they are infested or unhealthy. @Oortcloud That was my position. That no intelligence or consciousness was involved. It's my understanding that Aces was exploring the possibility that a "form" of consciousness was involved in plants that we simply had not discovered yet. But that's just my perspective. Perhaps Aces will amplify on that. It's my understanding that Aces was exploring the possibility that a "form" of consciousness was involved in plants that we simply had not discovered yet. But that's just my perspective. Perhaps Aces will amplify on that.That's exactly it. Here's my dilemma, and let's use Oorts example, as follows: He said.. "The trap and folding are reactions to stimuli when the plants are touched. There is no conscious thought, only a reactive response."To which I would agree, it's only a reactive response. Now let's put the hot tip of a lit cigarette on your hand. As soon as you felt pain you'd jerk your hand back, right? Only a reactive response! (No different than the pl... Autonomic nervous system. Simply because we perform certain actions without conscious thought and this appears to be the same as plants doesn't convey consciousness to plants because we are conscious. I'm not sure if this applies, but I've met quite a few people that consciously allowed themselves to be burned by cigarettes without any medication to numb the effect. A game called "chicken" was very popular in a local bar during my early years where two people would place a wager and then put their arms together and drop a lit cigarette in the crease where their arms met. The loser was the first to move their arm. Some of the guys that went in there had many full length cigarette burns along their arm. While there is definitely an argument against intelligence there, it is a prime example of a conscious choice and act of something acting outside its own interest. Equally interesting is the case of trained persons being able to control their autonomic responses such as heart rate, respiration, body temperature.Our ability to control response to pain is well documented. IMO, your example is a prime example of an over developed stupidity gland! |
