OK. The idea that we don't "see" anything at all is interesting. I must have missed it. (I'm assuming it's in this thread somewhere?) — Ludwig V
I agree that the images on our retinas are 2D. But I would say that our brain has access to information about the 3D world through somato-motor engagement (with some reservation about hearing) and I think that affects how the brain interprets the 2D information and consequently how we see it. I think the distinction between our brain doing something and us doing something matters. But I admit that what conscious experience amounts to is not at all clear. — Ludwig V
You would not be wrong to say that we both see the same markings in a different way. — Ludwig V
You mentioned attention. When I look through a telescope or microscope, I do not attend to the image as such (unless I need to focus the lens, or clean it) — Ludwig V
The case of writing is somewhat special, in that writing is 2D, and the writing in the image on my retina is exactly the same as the writing in the 3D book. So we shouldn't have a problem in agreeing that what I see is the writing (or the marks). What's going on with 3D is still unclear. — Ludwig V
In each case, your experience will be different. — Ludwig V
The issue for me is that incorporation of the insights I mentioned can inform and transform the content of the hard sciences, just as it has already begun to have its effect on biology, neuroscience and cognitive psychology. — Joshs
It is marks on paper and how those marks relate to other parts of the world. The difference in vocabulary depends on and signals a difference in how we are to think about the phenomenon. — Ludwig V
But, at the same time, they do work for many purposes, and we've been quite clever about working out ways of pushing the boundaries. — Ludwig V
or the two are inter-dependent. — Ludwig V
Different sciences talk about things in different ways. Some rely on reductive causal abstractions, some begin from the contextually particular circumstances of persons in interaction. It’s not a question going into the ‘depths’ of an inner subjectivity but of staying close to the interactive surface of intersubjective practice and. it abstracting away from it with with claims to pure ‘objective’ description. — Joshs
Science has little to say about your subjective experience as it is impossible to capture. Its not just science, but anyone. Even the closest person in your life doesn't know what your actual subjective experience is. — Philosophim
It's as if you were to say that all writing is just marks on paper etc — Ludwig V
.. and you only have experiences of your actions because you act. — Ludwig V
I'm particularly interested in whether you think there is such a thing as indirect perception and what that might amount to. — Ludwig V
On "conceptual schemes", I should add that there is quite a lot that Davidson says that I agree with. I think he is right to argue that there is not one single conceptual scheme that all human beings share. I do maintain, however, that our world includes many partially incommensurable schemes - partly shared and partly not. Further, the difference between scheme and content is not anything like as clear-cut as his argument requires. On the other hand, I accept that the differences in thinking can be expressed as beliefs. I think, for example, that belief in God is not a straightforwardly empirical scheme, but the anchor of a way of thinkng about the world that is conceptually different from the way an atheist or sceptic thinks about the world. But then, Davidson doesn't seem to recognize that there are different kinds of belief. — Ludwig V
what I see is the ship or star. — Ludwig V
But that does depend on linking perception with action rather than experience. — Ludwig V
If you suppose anything like an image or model in the brain, the question arises how the brain can access it in order to apply it to the incoming information. The answer is always an observer of some kind. But then, that observer will need to construct its own model or image and there will have to be a second observer inside the first one.... I'm sure you see the infinite regress that has begun. The brain is not an internal observer - unless you call it an observer of the outside world. — Ludwig V
Some images are images of something, some are just patterns. If you treat them all as of the second kind, you have lost the significance of the image. — Ludwig V
I don't understand what you mean here. — Ludwig V
If "directly" just means inside the body, then obviously I cannot be directly acquainted with objects outside my body. — Ludwig V
So, classification needs to be agreed before the facts can be agreed, and if people are in the grip of the idea that animals are just machines, that agreement is not possible. — Ludwig V
We do agree pretty much on how the eye works, yet we describe the facts differently. Our disagreement is not about the facts, but about agreeing a coherent way of describing them, i.e. how to think about them, i.e. a coherent conceptual structure for understanding them. It's not a straightforward task. — Ludwig V
Ironically, much of the recent neo-Aristotelianism flows from a growing dissatisfaction with the artificiality of possible worlds semantics. We are slowly correcting modern errors, first with Kripke's modal form of essentialism, and then moving with Fine and Klima towards more traditional and robust forms of essentialism, that do not rely on the overrated device of possible worlds. — Leontiskos
Perhaps not. But a knuckle joint or a thumb or an arm or a spine can. — Ludwig V
None of those is true of images of the car, no matter how many you accumulate. — Ludwig V
wouldn't object to that. But what validates the inference? There must be some way that you can compare the image of a 3D object with the 3D object. But you seem to deny that we can. — Ludwig V
So the image of my car is no different from an image of starship Enterprise or a dragon - and even in those cases, we know what it would mean to see the real thing, even if it never happens. — Ludwig V
It depends what you mean by "literally". For me, when I walk through my front door, I literally see my car. If I only see the image on my retina, then I don't see "literally" my car, but an image of it. — Ludwig V
An image is always an image of something else, never the real thing. So my anchor is the real thing. That's what makes the image of a car an image as opposed to a complex array of coloured shapes. — Ludwig V
But it is not the same as a disagreement about the facts and cannot be settled in the same way. — Ludwig V
The problem here is about the meaning of "direct" and "indirect". — Ludwig V
If what we see is the image on our retina, how is that any different? — Ludwig V
The image is more like a lens, by means of which I see my car. — Ludwig V
But I don't see that we ever see that image, because it is extensively processed, including the amalgamation of two images. Don't forget. that retinal image is broken up into what, presumably is an encoding that is quite different from any image.
I'm not sure whether to count the result of comparing two images or the extent to which our lens needs adjusting to produce a clear image a visual cue. It could go either way, I suppose. — Ludwig V
"What you see" is ambiguous. — Ludwig V
I partly agree with that. But what is learning is not me, it is, let us say, my brain. I don't ever hear two sounds, one for each ear and then realize that I can deduce where the sound is from that. I hear one sound, located in space. The learning and the processing takes place way "below" consciousness and involves an encoding process that is nothing like a sound even though it is caused by sound — Ludwig V
trompe l'oeil painting. — Ludwig V
Please let me know if I am annoying you. — Ludwig V
But the disagreement is not a question of evidence, but of interpretation of the evidence. So Davidson's thesis that we can abandon talk of conceptual schemes and return to beliefs and experiences seems to me to be false. — Ludwig V
But how could we have 3D bodies in a 2D world? — Ludwig V
BTW, you are forgetting that we have 3D hearing as well. — Ludwig V
We have learned to interpret 2D pictures as 3D scenes. If all we experienced were 2D, how could we even get the idea of 3D? — Ludwig V
A non-minimalist would have said "to a greater or lesser extent" and cut out all the "maybe" qualifications. — Ludwig V
But none of that is 2D information. — Ludwig V
It would seem you are a minimalist on this question. — Ludwig V
Yet we experience them in 3D. — Ludwig V
We don't make the inference - the results of an inference made "unconsciously" are available (are reported) "directly". — Ludwig V
That fits with Wittgenstein's idea that human life and practices are the essential context for everything. It would seem that he did not see any similarities with non-human life. This is somewhat puzzling to me, though I would not automatically extend that understanding to all life. There is disagreement among human beings about that.
There is more to be said about how we deal with extreme - non-regular - contexts. — Ludwig V
Yes. But that's a misunderstanding of what intelligibility is. Intellgibility is not black and white, but a spectrum. He seems to think that "conceptual schemes" are a tight logical structure which is either completely intelligible of completely unintelligible - which leads to his reductio. That fits with what appears to me a very naive view of translation as just a set of equivalences. That's seldom or never available — Ludwig V
That's very close to what I would call a concept. — Ludwig V
Not quite right. We have 3D stereoscopic vision because of our two eyes; it fails at larger distances, but it works well at smaller distances - as the 3D films show. Our ears manage to give us 3D hearing as well. — Ludwig V
I dont like the metaphor of lens as a depiction of the relation between mind and world. It implies a detached, subjectivist view of how we make sense of the world, as though the information contained in reality is already sitting out there and all we have to do is notice and process it internally. — Joshs
We don’t pick out factual aspects of the world based on relevance for our purposes, we actively do things with the inanimate and social world, and the patterns of our doings forms normative structures of intelligibility and purpose which determine HOW the world appears meaningfully to us — Joshs
IF that concept gets its sense from a discursive system of practices that is only peripherally shared by you. — Joshs
In particular, it is not clear that conceptual schemes correspond in any helpful way with "models" in cybernetics, whatever they are. — Banno
It seems to me that it is the various explanations for how and why the world we perceive is as it is that involve various conceptual lenses (conceptual schemes), and that is not that what we perceive is determined by conceptual lenses, but rather by what is noticed, what is selected, which in turn is determined by what is of interest or use.
I think part of the motivation for deflation arises from the position that truth applies only to sentences — Count Timothy von Icarus
But if you can imagine a dog does not need to think to yelp and leap from being burnt, why can't we imagine the dog is behaving according to the exact same impulses in everything the dog does? Like a plant cell photosynthesizing - wherefore belief as a component of these motions? — Fire Ologist
Organisms are quintessentially beings instead of mere heaps (existing according to a nature, not solely as a bundle of external causes) because they are self-organizing, self-governing, and most of all, goal-directed. The parts of an organism are proper parts of a proper whole because they are unified in terms of a goal that is intrinsic to the organism. This is the idea of "function" and teleonomy in biology. The parts of a flout or rock are not organized in this way.
And perhaps, ↪Arcane Sandwich, this is also a way of finding a via media between permissivism and eliminativism.
— Count Timothy von Icarus
Conservatives would reject the first premise: there is indeed an ontologically significant difference between bikinis and fouts. But that difference can't have anything to do with the question about scattered objects — Arcane Sandwich
The idea of an ontological potential endows even simple physical systems, such as rocks, with a kind of weak coherence and ‘monitoring’ of internal states...
Namely, the FEP covers a broad class of objects as cases of particular systems, including adaptive complex systems like human beings, simpler but still complex systems like morphogenetic structures and Turing patterns, and even utterly simple, inert structures at equilibrium, like Objects that have no structure or no environment, either of which fail the FEP for obvious reasons, exist at one extreme...
Although it does not seem that evolution is always very gradual (e.g. proposed cases of observed speciation). There is evidence for rapid evolution due to bottlenecks, fertile hybrid offspring reproducing in the wild, etc., and the whole EES controversy. It's an open question how larger shifts in anatomy (e.g. hands to wings, hands to fins, fins to hands, etc.) — Count Timothy von Icarus
Yet neither is the argument: "Either species are defined rigidly in this way, or they don't exist," a good one. It's a false dichotomy. — Count Timothy von Icarus
Processes can be more or less stable. We can think of an entire ancestral line as a process. For some species, such as the cockroach, the process has been in a fairly stable equilibrium for an extremely long time, perhaps 100-300 million years. — Count Timothy von Icarus
Yet if two species are indistinguishable, even upon close inspection with instruments, then in virtue of what could they even be said to be "two species?" — Count Timothy von Icarus
But it's the thing signified by the scientific term that existed before man existed, not "whatever the term can apply to." I hope you can see the problem here. Insects can't have existed before man and be defined by however "insect" is used in normal language, because the term is used in various ways in different contexts in normal language. This would mean that some things would be both insect and not-insect. Nor can they be defined by "however science currently defines 'insect,'" since this would imply that whenever a scientific term is refined the being of past entities is also thereby changed. — Count Timothy von Icarus
This seems like an argument from ignorance. I know of no reputable biologist who claims that there have actually been very many hominid-like families throughout the history of Earth, just "lost to time." There are just the fairly recent hominids. And the same are true for many families.
What's the idea here. "A man like species could have walked the Earth with the dinosaurs, or any time since, but we just don't know about it." But not only this, but it's "very likely." I don't think so.
The idea that very many families of hominid-like animals have evolved many times is highly unlikely for a number of reasons. — Count Timothy von Icarus
And "fish" was used to describe whales for a long time. But clearly, while whales were whales before man, whales were not both fish and not-fish during this period. — Count Timothy von Icarus
Anti-essentialism can only get one up to a certain point. "Essence" might be an ugly word for an analytic ear, yet Kripke argued that the essence of a gold atom is the property of having an atomic number of 79, which is the number of protons in the nucleus of a gold atom. Kinda hard to argue with that, even if one isn't an essentialist. — Arcane Sandwich
even ambiguous — Count Timothy von Icarus
But that is not what the fossil record suggests for man, for just one example. — Count Timothy von Icarus
There have not been "very many species indistinguishable from man" existing throughout the Earth's history. There have been, on contemporary accounts, just the one. And this certainly wouldn't be true for domestic animals either. — Count Timothy von Icarus
Unless you are merely speaking of the transition from wolf to dog, in which case what of it? Yes, domestication is not a binary. Yet the aurochs is extinct, the cow is not. More to the point, a stegosaurus is not a dog, an oak is not a dog, a rock is not a dog. These are quite discrete distinctions between dog and not-dog. — Count Timothy von Icarus
If we cannot find it, shall we conclude that either no dogs ever die, or that none have ever lived? Or perhaps that "life" and "being a dog" are mere cultural or mental constructs, ens rationis and not ens reale? — Count Timothy von Icarus
For example, there are curlterpillars: caterpillar-like objects that begin to exist when a caterpillar rolls up into a ball. There are incars: vehicles that look like ordinary cars, but that can only exist when they're inside a garage. — Arcane Sandwich
However, words generally try to focus on the actual, not the potential. The act of being a dog is what stays the same in all dogs. We could well imagine some sort of dog, bee, elephant fusion (horrific) and ask: "when does it stop being a dog and become a monster?" Yet no such animal actually exists, it is ens rationis, a being of thought. Language evolves through our interactions with actual beings, so we should only expect that our words will tend to indicate the beings we actually find around us. Language evolution isn't arbitrary after all. — Count Timothy von Icarus
But you don't tend to get the same sort of disagreements re lions, oaks, or carbon. — Count Timothy von Icarus
will probably come pretty easily, because, while a cultural role, it can be represented with clear, concrete characteristics. — Count Timothy von Icarus
The dog doesn't know that the blue ball has anything in common with their blue collar or with the blue cabinet in the living room, for instance, unless its being trained and rewarded with food when it point to blue objects — Pierre-Normand
