You speak of selection within our species but the time of such
evolution (if there was any) is nothing in comparison with the time of
macroevolution, the one which led, in particular, to the emergence of
our species.

Well, I see you are a fan of Griffiths & Wilkins' "truth tracking"
concept.
I agree that an organism has a kind of "umwelt", ie, a specific mode
of interaction with the environment. However I don't think that other
species than Homo sapiens (perhaps Homo neenderthalensis and Home
erectus?) have/had what can be really called an internal
representation of the world.

When you rejected religion. And more broadly this discussion is going
on without recognition of people's subjectivity, their emotion
tracking, tracking that which can only be subjectively identified, the
human spirit.

I was on a tour of the Three Gorges on the Yangtze River a number of
years ago, before the dam was built. We were on a tributary near
Wushan in small steamers and the river was somewhat crowded with
touring boats filled, like mine, with tourists. One of the boats
pulled alongside ours and someone in the other boat waved frantically
for us to open the window. When we did, he leaned out and shouted "Do
you have any Grey Poupon?"

Call it what you will. They do have something in their brains that
lets that manage in the world. It is not all just stimulus-response
reflex, you know.

I fully agree with you that "it is not all just stimulus-response
reflex". Of course the perception of the local environment by animals
with a central nervous system (CNS) is integrated in a complex
specific manner and then processed in order to produce adapted
behaviors. However I wonder whether it is possible to say that all
these animals have "an internal representation of the world".
Regarding the notion of "tracking-truth" I realize that the scientific
and the philosophical approaches are actually "tracking-truth"
approaches because

Do you agree that everybody is free to defend one's view in this
forum? Then I am sorry for you but I am definitively an atheist. So I
defend my view about religion and more generally about metaphysics.
However I have no reason to sideline subjectivity. For example I think
our emotional brain is very important to explain most of our behaviors
and reactions and our subjectivity is mainly led by our emotional
brain.
Of course I understand that this interpretation doesn't suit you at
all.

Everybody has excuses to ignore the spiritual domain, intellectual
excuses have no special significance. What is it then that you are
subjectively identifying?

Do you understand the concept of "example"? I gave an example that
coincidentally involved a human. I coudl just as well have used a puma

so, having such a concept allows us to make distinctions tha then play

I have no problem with that. It is a different story when you say that
non-human animals have "an internal representation of the world", with
specific and well-defined beliefs.

If you agree with the concept of "umwelt" you would also agree that
different groups of animals with a CNS have very different modes of
representation of their local environment. One is not truer than the
other one, but each is adapted to the corresponding group of animals
and stems from its evolution history.

Sorry but your answer seems specious to me and doesn't convince me:
when you track something you have an intent.
I maintain that natural selection tracks nothing, it just selects the
surviving organisms, that is all. To explain how such a non
intentional selection combined with the other mechanisms of evolution
led to the extant organisms is, as you know, a very long story of
about 4 billion years. There were numerous steps with many different
mechanisms, constraints, events etc. I agree with you that the final
results are impressive and seem to be teleological. We both agree that
the results are not teleological. Where we disagree is on Griffiths &
Wilkins' interpretation: you consider it is a good one and doesn't
mean that the results are teleological, I consider it is not because
it would mean that the results are indeed teleological. That is the
major point of our debate.

What you just describe is that we differ on my insistence that
evolution produces a result that is "seemingly teleological" whereas
you insist that the result is "truly teleological" and hence cannot
have an evolutionary basis.

I think perhaps there is a misunderstanding (perhaps because of my
English ...again!).
We fully agree that:
1. evolution produces a result that is "seemingly teleological";
2. it is not teleological in fact.
Where we disagree, I think, is in the interpretation of how natural
selection works.

Now I am very confused but I am happy simply to agree that we disagree
on something.
Just in care there is misunderstanding on one point: in no way do I
think that natural selection is in any way teleological even though
biologists frequently use teleological language as a convenience in
describing aspects of it.

So we don't disagree anymore ... except perhaps on how we consider
Griffiths & Wilkins' paper.

And who said this? The argument is pretty much agnostic to the type of
internal representation that is present in the species under
consideration

Yes, because it is a hunter that does the tracking. Whether or not a
specific type of tracking is intentional or purely mechanical depends
on the nature of the agent, not the nature of tracking. Your argument
is exactly the same, and just as misguided, as backspaces' who
complaints that "selection" always must imply intend. Sometimes it
does, sometimes it doesn't, a good theory makes clear which type of
selecting is meant Smae with "tracking", the argument as developed in
thae paper makes it abundantly clear that as the environment is the
agent here, no intend is involved, needed or otherwise in play.
Quite on the contrary as a matter of fact, as my debate with John
showed - where there is intend, we can't assume truth tracking any
longer (I can intentionally breed dogs whose internal representation
of their environment is wrong)

that may or may not be teh case. If you have two species that compete
for food, and one of them has evolved a mechanism to judge distance to
food more accurately ("truer") than its competitor, then ceteruis
paribus the one closer to the actual distance might eventually replace
the less accurate one.

Again, nothing there contradicts the argument in the paper

I am sorry but I find totally obscure your sentence "The argument is
pretty much agnostic to the type of internal representation that is
present in the species under consideration".
Can you clarify it a little bit?

This argument is specious and dangerous because when it is said that
something tracks something, even if the subject is a thing the ID
proponents will rightly reply that there is an attempting to hide an
intentional intelligence behind this thing.

I agree with you if you say that the environment can play a role, as
many other factors, in the selection of the surviving. It is another
story to say that selection can be a "tracking-truth" process in some
circumstances.

I am sorry but you misread what the concept of "umwelt" means: it is
not an anecdotal skill it is a whole mode of representation of the
local environment by a given group of animals given their perceptual
capacities. Then it is a nonsense to say that the umwelt of a given
group of animals is truer than the umwelt of another group of animals.
Both umwelts are adapted for the use of each group in their respective
environment (as already specified below).

The notion of tracking is not acceptable otherwise you invite the ID
proponents to step into the breach.

It starts:
"In order to navigate successfully through its environment, an animal
must use its brain to keep track of where it is. Recent studies have
shed light on how animals do this: an important clue for how the
animal’s location is represented in the brain has been provided by the
discovery of ‘grid cells’ in the entorhinal cortex of rats. Each of
these cells acts as if the surface of the animal’s local environment
has a triangular grid painted all over it — the grid spacing is two or
three times the length of the animal — and the cell is active whenever
the animal is at a vertex of any of the triangles, but inactive for
locations in between the vertices"
It concludes:
"The results of these studies point to the entorhinal cortex as part
of a neural map of the spatial environment, and provide insights into
the way that the map is organized."
It has long been known that animals have representations (maps) of
their own body, both sensory and motor, and of the visual field.

I can't speak for Marc but I subjectively identify that you have a knack for being annoyingly repetitive with the nonsense you spew on this group. Then you tend to go off and become quite offensive. Since I know how I subjectively feel about your behavior I use my gut response about you to formulate a model of what others may be feeling about you subjectively and assume it can't be too different from my subjectivity. Thus I am in touch with my subjectivity and may have an insight about the subjectivity of others.
You, on the other hand, are not easy to empathize with. I really don't want to know what sort of dark subjectivity is boiling inside you to make you say some of the things you say.
I fear, subjectively of course, that you are 怨霊 or Onryō, a vengeful spirit of Japanese folklore and popularized in recent movies.
If I had to believe in spirits I would subjectively say you are akin to Sadako Yamamura in the first Ringu movie and woe be to anyone who falls victim to your special powers. You could be posting from a well hidden by the floor of a cabin for all I know and you want your spirit to go viral and destroy the world.

I thank Mark Isaak for the paper.
Actually there is a misunderstanding. I have no problem with that kind
of paper and expect such data. Of course I knew "that animals have
representations (maps) of their own body, both sensory and motor, and
of the visual field" and thus a representation of their local
environment (I wrote it actually in my posts) as, according of
evolution, there cannot be a deep gap between Homo sapiens and the
other animals.
What I have understood was at stake was a representation of the world
with specific and well-defined beliefs: this seems to me much more
than a representation of the local environment. Don't you think that
to have such beliefs an animal should not have acquired a
sophisticated language?

Nice summary. However, I (now) think that beliefs are not inherited,
only dispositions to acquire them in certain ways. That constraint is
what gives us our Umwlet; that is, the swignificant cues in our
environment to which we respond, and from which we construct our
commonsense ontology (and scientific ontology).
Quine thought that our "quality spaces" - broadly speaking our
propensities to treat things as similar nd hewnce come up with natural
kinds in a natural fashion - were inherited, but I don't even think
that. My present opinion is that we inherit merely dispositions to
acquire types of content, including propensities to treat some things as
more similar than others.
So models of the world, or beliefs about the world, are not inherited as
such, but constructed from, as it were, a common building set, much like
languages and the disposition to learn languages.
