We seem to be at a bit of an impasse with our respective positions in this debate.
I am trying to show that atheism, especially an atheism based on materialism and naturalism, is a reasonable and logical position to hold.
In order to do so, I present arguments based on sound reasons and reasonings. I also try to structure my arguments as consistent with formal logic. That is what reasonable and logical means.
David now claims that this atheism is not reasonable or logical.
I would expect him to go against my arguments, show that my reasons are unsound or that my logic is faulty. But he doesnt
he even denies that he is supposed to do so.
He could show that my position is untenable because a contradicting position has been shown correct. He also denies that he should do that. Yet that is what he tries to do, in a very roundabout way.
He presents me with a couple of challenges and questions, implying that, if I dont answer these
to his liking, my position is shown wrong and his position right by default. That is an erroneous inference.
The questions and his presentation of scientific facts these questions are based on - are riddled with errors and erroneous conclusions. They are not based on sound reasoning.
So in his attempt to show that my position is unreasonable and illogical (utterly unreasonable and a complete hoax), he relies on an approach that is in itself unreasonable and illogical.
Lets go backwards through his argumentations.
He bemoans that the AW
rests on speculations and unproven theories. That shows that he doesnt understand how science with its approach of methodological materialism works. It also, deliberately, ignores and changes my own post, which said
speculations and theories
based on positive observations and nothing else.
Theories are never proven, they can only be disproven. They are not observable reality in themselves
they are a system of inferences or conclusions made from observable reality. Every piece of evidence the positive observations need either to comply with the theory, supporting it, or going against it, thus weakening or disproving it. And they
can be disproven, provided their initial premises can be shown wrong or contradicting evidence comes up. But as long as their premises stand unchallenged or no contradicting evidence exists, they are reasonable and logical.
An example: Our outdoor thermometer was found broken on the floor. I speculate that it could have been thrown down by those pesky neighborhood cats.
Observable facts: there are a number of cats in the neighborhood. Cats have been seen previously climbing around our fence, where the thermometer was placed. Cats are known to interact with objects.
My position of cats done it is reasonable and logical. It could still be wrong though. It could have been martens or birds or the wind or a material defect. But all these speculations, based on observed facts and sound reasoning also makes it reasonable and logical to doubt and reject a claim of it fell because of a battle between angels and demons
which is not based on any observations.
His questions about life as an emergent property are in the same way unreasonable and illogical. He asks for proof which science doesnt deal in, mathematical equation showing that this is the way it occurs which I did never claim exist, and observed life arising from non-life which is not necessary for a reasonable assumption.
The definitions of biological, materialistic life - the attributes used to distinguish it from non-life -are all (potential) behaviors. In these definitions, life is necessarily an emergent property. There can be no behavior without something that behaves.
Mathematical models show all the time that systems can have properties that their individual components do not have
they emerge due to the make up of the system. You dont need a research paper for that
any school book will do that.
The observation of life from non-life will most likely never happen in the way he wants to have it
because his expectations are incorrect. But even in the existing scientific hypothesizes, such an observation is not necessary to show that these systems are reasonable. There are enough observations in existence to show that all these systems are possible, and nothing to show that it is impossible.
In a similar way his question about the origin of cells and DNA is unreasonable and illogical. First, he seems to assume that cell is the simplest form of life that exists, and that this simplest of cells had to spring fully formed from its non-life origin. This is incorrect. Cells or amoebas are already highly evolved systems. Earlier systems are based on simpler components. These simpler systems have been shown to be able to form by materialistic means. Also, there are forms of life still existing today that do not use cells or DNA.
A primer to start with would be
the University of Berkeleys site. It gives a good introduction into the theories about the origins of life and the observations and experiments that have already been made.
His reference to the Second Law of Thermodynamics is something that he really should know better not to use. The common rebuttal to his claim should be enough: that the 2LoT refers to the overall entropy of a closed system. But it is his mention of the 2LoT as an established Law of Science which applies to all Material and Biological Systems within our Universe that shows the illogic of his arguments.
We see the emergence of complexity from simplicity all the time in Material and Biological Systems. If the 2LoT forbade this, life would not exist. Every single endothermic reaction would not exist. But we see them existing.
His reasoning here is The 2LoT forbids this, therefore it must be a supernatural explanation.
precisely the logical fallacy he accused me earlier in his post of committing (which, BTW, I did not).
On the other hand he completely ignores that, while the 2LoT allows for loss of entropy in certain systems, the configuration of this system plays an important role. You dont have to have only the correct matter, but also the correct energy. If you accelerate (put energy in) flour, water and eggs, you will get a mess. But if you heat it (put energy in), you will get a cake.
The more reasonable explanation for these apparent contradictions and misconceptions: his interpretation of the 2LoT and its consequences are false.
The fine-tuning argument now is a really interesting one, and would deserve a better presentation than the one David gave here.
I will not go into depth here with the nonsensical parts, the website he cited about the incredible design of the Earth. A simple reminder of Douglas Adams famous puddle should suffice.
The question about many Laws of Physics/Chemistry/and Mathematics is also rather weird. As I said earlier, the laws of nature do not determine how something behaves, they describe it. If they were different, they would not describe the system they do now. These laws just cannot be different.
For the natural constants, this question is open. We just do not know if a different setting is even possible. But even if we assume that, this in no way serve
to be a nail in the coffin of the AW. It isnt that this phenomenon isnt known there are enough non-theistic hypothesizes out there that try to give an explanation.
Yes, these are unobserved speculations. But in this they are not different from the hypothesis of a supernatural creator
and this speculation has a major flaw in my view.
I already said this in my previous post, only to have it completely ignored. But it is an important argument: the idea that certain values have to be just so, in order for the whole system to work only makes sense when you already have a whole system for it to work in.
We can only say how footballs, golf balls or pecan pies need to be, because we know the existing framework of the universe that have to exist in. If we hadnt this framework, we couldnt make these statements.
That means a designer of a materialistic system must work from an already existing materialistic system.
I dont claim to know the answer to Davids question. Maybe all these constants are inherent in existence
they just cannot be different. Maybe they are different, and we are in the position of the puddle
we are here and not there, because here allows us to exist and there doesnt. Or maybe we are just lucky
the constants are arbitrary, but by chance are just this way.
I dont know. But that doesnt mean that my position of doubt in a theistic position is unreasonable or illogical. I presented David with two ways to show that, but he has chosen not to go that way.
His last set of questions, the questions about the Big Bang again show his overly simplistic approach to both the cosmological as well as the philosophical questions of that topic.
All his talk about the experts in this Field agreeing ignores the real points they are agreeing on: what we see now came from something quite different, a long time ago. What this something quite different exactly was is unknown. Even the famous singularity is a hypothetical construct
our current models of physics do not work at such a proposed state (So much for fine tuning).
But there are potential explanations for such an event, and certainly someone as proficient in science as David knows them all. All of them are based on naturalistic, materialistic systems
none of them proposes a supernatural creator.
His questions show that he is unable to even consider those explanations, and that he has to introduce his own speculations and unproven theories into a scientific topic. Talk about that which didnt need to exist or being willed to exist are philosophical/theological speculations that are unevidenced, contested and not conclusive.
The general answer to his questions here is also much simpler: we have a lot of existing evidence for things arising from natural means. That even includes the things that humans do, which are not simply willed into existence. For such a method of origin, we do not have a single piece of evidence.
Even if the exact causes remain unknown, Davids questions do nothing to show that such an assumption is impossible or unreasonable. They do nothing to show that an alternative explanation is correct. Having refused to use the two methods that could indeed make his point, he fails to show the naturalistic explanation as unreasonable or illogical.
Now I dont think that my explanations here are compelling David (or any other reader) to become an atheist. This wouldnt be the intention of this thread. Nor is the intention to present reasonable or logical arguments for converting to atheism.
But to hold to an atheistic worldview is reasonable and logical. It is based on sound reason and solid logic. David has not shown that it is not.
And to close this interesting debate for my part, an idea for our next debate: in part 1 of his latest post, David mentioned that while we have some materials , we also have as a reality NON-material entities. I challenge this assertion that he made without any evidence. If he makes such bold claims, it should be no problem for him to support it.
