Consciousness fits very well with evolutionary theory. If you want a specific explanation of how it works, that's a job for neuroscience, but the increasing capacities and capabilities associated with consciousness in vertebrate lineages show a good correlation with increasing complexity and flexibility of lifestyle, particularly social interaction. It's not hard to see why those capacities and capabilities, including a unified sense of self and awareness, might have a selective advantage consistent with the lifestyles & environments they're found in.But it wouldn’t be an argument from incredulity unless evolution gives an explanation and he just fails to grasp it. He’s saying that evolution doesn’t give an explanation of consciousness at all, that it just tacks it on as nothing more than some mysterious byproduct that just shows up at some point. Whereas the development of physical structures and the mechanisms to get there that take place with evolution are described very well. So the consciousness part is inexplicable, and if something in a theory is inexplicable it can’t be called an argument from incredulity to not understand it because the theory didn’t even explain it.
Not quite. You could say that, for example, that gravity favours the production of increasingly large clumps of matter because of the inherent tendency of one mass to attract another; that is teleological in an Aristotelian sense - it is the nature of matter to gravitate. But the emergence of complexity and order is only thermodynamically favourable under specific conditions, it's not some universal tendency or characteristic of the universe - if any of the conditions are not suitable there's a far stronger tendency to destroy complexity and order (increasing entropy), and in the production of complexity and order, far more disorder (entropy) is exported to the wider universe.Wait how are these two paragraphs different? Isn’t suggesting an inherent tendency towards complexity the same thing as laws favoring the development of complexity?
I get the impression that Nagel is actually trying to turn the accusation around and claim that holding onto a belief in materialism is an argument from incredulity, by denying that there are enough hints to sink materialism. However he isn’t too overconfident about it because he does always admit that he has no positive theory to replace it with.It's an argument from incredulity to say that because we don't understand how it is produced, it couldn't have been produced by evolution.
Are you of the opinion that life is extremely rare in the universe then?Not quite. You could say that, for example, that gravity favours the production of increasingly large clumps of matter because of the inherent tendency of one mass to attract another; that is teleological in an Aristotelian sense - it is the nature of matter to gravitate. But the emergence of complexity and order is only thermodynamically favourable under specific conditions, it's not some universal tendency or characteristic of the universe - if any of the conditions are not suitable there's a far stronger tendency to destroy complexity and order (increasing entropy), and in the production of complexity and order, far more disorder (entropy) is exported to the wider universe.
So the inherent tendency of the universe is towards increasing disorder, but in the right circumstances, this can result in pockets of order & complexity, as long as it increases disorder even more elsewhere. Ironically, complex systems are very efficient dissipators of energy and the most efficient way of increasing disorder in the wider universe.
Hey I gotta give you props btw, you nailed not only the author but the exact book that shocked me lol! I really enjoy his writing style, I have another book from him I still have to get to so I’m excited that it sounds like he doesn’t just repeat himself in every book (A View From Nowhere). Yeah I don’t really get into the fine tuning arguments, but I do find it beyond random chance that principles of self assembly start to occur at various levels. There’s of course biology, but there is also said to be an inconsistency in the law of thermodynamics, inside of a closed system you get non-uniform pockets where abundant growth bursts forth that greatly outperforms other areas of that closed system.Possibly, if Nagel had understood this, he might have come to a different conclusion, I don't know...
It’s so crazy, it’s not looking good. I think about Einstein’s quote that World War 4 will be fought with sticks & stones. I actually can’t even believe that homo sapians even made it through several ice ages that’s so crazy, if not it would be back to square one. WHEN we destroy ourselves this time I wonder what the chances are for the super elite with their underground bunkers and their elaborate setups? If the atmosphere becomes toxic for long enough even they are done.BTW, The problem we have with global warming is that in maintaining and increasing our complexity and order, we very efficiently convert low entropy high-frequency photons from the sun into high entropy low-frequency photons of heat, radiating ~20 infrared photons for every incoming visible or UV photon we use. Unfortunately, the high entropy heat photons are not being radiated away as quickly as we produce them - partly because we use them to produce greenhouse gases...
That's not surprising for a philosopher. They're always trying to discover the meanings of the words they use, such as 'exists', as opposed to actually doing the hard work of generating the data needed for assigning the meaning of such words... However he isn’t too overconfident about it because he does always admit that he has no positive theory to replace it with.
Yes I agree and you explained this far better than I could.It has been recently proven (in a published study) that when the assumptions, (which constrain the probabilities, such that Wigner's friend, in the Wigner's friend experiment), strictly 'obey' quantum mechanical laws, all of them cannot be satisfied throughout the thought experiment.
This then raises important questions about the notion of so-called 'persistent reality', (namely of the friend's perceptions). The proof, (a theorem .. here), demonstrates that it is impossible to consider the friend's perceptions, to be co-existent at different points in time.
This then, makes it questionable whether a quantum observer, in general, can consider their own past or future experiences, to be as 'real' as their present ones.
At least one of three key assumptions of quantum mechanics must be violated in this proof.
Which one is violated, then entirely depends on one's preferred interpretation of QM (as you appear to allow for, in your above response?)
What 'reality really is' however, is then subject to a specific, preferred, QM interpretation .. (which is clearly a philosophical choice).
I think that recent theorem above, argues that case quite nicely .. Ie: that what many scientist/philosophers merely assume as being a something which exists 'out there' .. and science is measuring, is just another philosophically held belief.
Whilst I appreciate your feedback there, I'm not so sure the latest update on Wigner's friend takes you as far as you may wish to go(?)Yes I agree and you explained this far better than I could.
Instead of looking up dictionary definitions and holding those up as the be-all-end-all of some discussion on the nuance of words like: "reality" and "existence", folk should consider actually do the hard work of deciding what they mean when they use those words, and watch for internal inconsistencies .. they always abound. They might also consider watching for circularities there as well.That's not surprising for a philosopher. They're always trying to discover the meanings of the words they use, such as 'exists', as opposed to actually doing the hard work of generating the data needed for assigning the meaning of such words.
Its as though all they ever do is look at dictionaries and think those are the true source of all knowledge. Dictionary meanings for words are always generalised to the point of ambiguity. One has to examine closely the context of particular words and then compare that with the context of where meaning is sought. Science categorises physical contexts by testing. Science thus undertakes the hard work, which produces the meaning of words like 'exists' .. but philosophers never do.
Re dictionary abuse, this should be posted at the top of every thread like a tobacco health warning.Instead of looking up dictionary definitions and holding those up as the be-all-end-all of some discussion on the nuance of words like: "reality" and "existence", folk should consider actually do the hard work of deciding what they mean when they use those words, and watch for internal inconsistencies .. they always abound.

It depends what you mean by 'rare'. Life as we know it is constrained by requiring conditions roughly similar to those of Earth's history. There are a vast number of planets out there, but only a small fraction of them are likely to fit that description. OTOH even a tiny fraction of a vast number can be large; there are estimated to be (very roughly) 21.6 sextillion (21,600,000,000,000,000,000,000,000) planets in the observable universe, which evidence suggests is only a small part of the whole universe.Are you of the opinion that life is extremely rare in the universe then?
I read it as part of a philosophy course on 'Mechanism and Purpose' - comparing the mechanistic view with the teleological view.Hey I gotta give you props btw, you nailed not only the author but the exact book that shocked me lol!
Yes, he's a good writer and he usually makes good arguments. He's probably best known for his paper, "What is it like to be a bat?" about consciousness. If you read him (or, indeed, any philosopher), it's always worth looking for critical comments on what you're reading. That tends to give you some perspective.I really enjoy his writing style, I have another book from him I still have to get to so I’m excited that it sounds like he doesn’t just repeat himself in every book (A View From Nowhere).
It's not an inconsistency, it's just how it works - there's a tendency towards maximizing entropy (disorder) and complex systems do that best at all scales when the amount of free energy is just right....I do find it beyond random chance that principles of self assembly start to occur at various levels. There’s of course biology, but there is also said to be an inconsistency in the law of thermodynamics, inside of a closed system you get non-uniform pockets where abundant growth bursts forth that greatly outperforms other areas of that closed system.
Agreed - but would you even want to be around to see how they cope?It’s so crazy, it’s not looking good. I think about Einstein’s quote that World War 4 will be fought with sticks & stones. I actually can’t even believe that homo sapians even made it through several ice ages that’s so crazy, if not it would be back to square one. WHEN we destroy ourselves this time I wonder what the chances are for the super elite with their underground bunkers and their elaborate setups? If the atmosphere becomes toxic for long enough even they are done.
Pity the only thing that thought experiment there does, is justify the original (and unstated) base assumption which is, life as we know it, probably exists elsewhere. Its a circular argument, which follows the assumed truth of its original posit. (Which is the only conclusion sound, philosophically based logic is capable of drawing in that scenario without external inputs from science).... but only a small fraction of them are likely to fit that description.
...
one planet in a million has roughly Earthlike conditions, and of those, life has arisen on one in a million,
...
But the incidence of suitable planets is probably higher,
Primarily I agree that the outcome of quantum experiments does bring up philosophical questions of how to interpret the findings regarding what constitutes reality. This supports what I was saying that scientists are measuring just one of those interpretations. I am also pointing out that many scientists assume that their interpretation is the correct one and all other interpretations are wrong.Yes I agree and you explained this far better than I could.
They should precede their comments with an: "As we understand it" because that's the role of the various interpretations - that is; to achieve understanding.Primarily I agree that the outcome of quantum experiments does bring up philosophical questions of how to interpret the findings regarding what constitutes reality.

From what I understand he uses human wellbeing and flourishing as the basis for measuring morality. He assumes human wellbeing as the basis and science is the measuring stick to establish moral right and wrong. So he doesn’t allow for any morality beyond the physical causes which is an assumed philosophical position.He does think that science can provide a moral framework, i.e. get ought from is; I haven't read 'The Moral Landscape' yet, but I suspect an intrinsic goal, an implicit 'ought'.
But some interpret disturbing the quantum state as the observer determining what we percieve as reality.Observer effect (physics). Basically, the fact that observing or measuring a system disturbs it.
Yes that’s what I am saying that more so than most other scientific findings the results of quantum experiments brings in philosophy more than ever because there is more than one way to interpret reality and for some this means that reality may not be as the classical interpretation claims.I wouldn't say classical physics is 'at odds' with quantum mechanics, it's more an emergent or limit approximation. I don't see how that 'brings philosophy into being something', unless you're suggesting that deciding on an interpretation of the quantum formalism is a philosophical exercise - are you? Otherwise, please explain what you had in mind.
Well because some say the observer is a person so this has led to a number of ideas to explain what is happeniong that involve the mind and consciousness as creating reality. This has also led to other ideas like hologram worlds and the multiverse depending on which interpretation you take. But primarily these are based on reality being determined by the observer and not being a set state as classical science has said.Not to my knowledge; can you be more specific?
Yes but not like they are now with the way quantum physics works. The number of ideas and hypothesis that seem to step beyond the classical measurements of physics that have been generated by quantum physics has increased 10 fold.Philosophers have questioned the nature of reality for thousands of years.
I'm meaning that the scientists assume everything has a naturalistic cause so even if a finding did fall outside the natural world i.e. miracles and had an effect on the natural world then I think scientists would try to come up with some naturalistic explanation. That is the default position of most scientists that there cannot be a supernatural cause and yet that is still a philosophical position to take.The first is near enough to pass, the second is cart-before-horse; if something has an influence on the natural (physical) world, it is considered to part of nature (physical). Scientists can't say anything about what has no influence on the physical world (unless it is a consequence of a physical theory), because there is nothing to talk about. As Wittgenstein said, "Whereof we cannot speak, thereof we must remain silent".
That you call it Woo suggests that you know that it is definitely something that cannot happen. But isn't that an assumption that everything must fall within the naturalistic view of measurements. If the science cannot measure ideas are regarded as Woo then it cannot really make claims that it really is Woo.There's a lot of misunderstanding of the observer effect and a lot of quantum woo out there.
I'm not sure about that. Don't they call consciousness the Hard Problem for a reason. I havn't heard of any definitive findings about consciousness either way. In fact from what I have read it would be near impossible for science to determine ideas like experiences and perception of the world into bits of matter to even test this.There's no evidence that consciousness is 'something beyond naturalism', and a great deal of evidence that it isn't. Uncritical reading can lead you astray.
I'm only going off what I have read where there seems to be a number of articles that claim the findings of quantum physics does point to fundemental changes in how we see reality and therefore this makes philosophy more relevant because it introduces questions and ideas beyond scientific materialist view.It seems to me that quantum physics changes nothing in the relationship between science and philosophy - but if you care to argue your case, I'll be happy to listen and agree or disagree as appropriate.
Such as?
Therefore as far as the scientific materialist position philosophy is at odds because there is no other interpretations.They should precede their comments with an: "As we understand it" because that's the role of the various interpretations - that is; to achieve understanding.
I'm not sure one can directly measure "an understanding" there either, eh?
How to maintain the integrity of the complete set of underlying QM assumptions however, eludes our understanding.
Well if I knew that, then I'd have the understanding, no?Therefore as far as the scientific materialist position philosophy is at odds because there is no other interpretations.
??What I don't understand is that science proves multiple opinions can carry the same weight, even if they are initially diverse.
The major thing is that science aims at being usefully practical. Religious faith only aims at reinforcing beliefs.Gottservant said:Evolutionists are basically trying to hog the finish, when faith arrives at the same time any other opinion does.

So just don't believe it.Yes but if you are going to discover something: you need faith to believe it.
