There are some statements that could not be false, no matter how the things in logical space are arranged. Mathematical and logic truths are amongst these. These are in a relevant sense independent of how things are. These are among the necessary truths. They are true in every state of affairs.1. Saying that "....then this fact about the world is a necessary one" seems incorrect. A fact about the world is not because of the nature of logical structure, but whether a possible state of affairs is true or false. — Richard B
Necessary truths are true in any arrangement of logical space. So if a statement is false, at the very lest, it is not true in every arrangement of logical space. But that doesn't mean that is says nothing. That it is not true that the cat is on the mat does tell us something about how things are arranged in logical space.2. Saying that, "Well, if something is false, it's obviously not necessary true." How can proposition that that says nothing, follow from a proposition that says something? From a proposition that says something about the world, how is it obvious that it implies a proposition that shows logical form but states nothing about the world. — Richard B
Yes, I can see your discomfort. Can we perhaps work on that?However, when we bring in the metaphysical talk of possible worlds and rigid designation, I start to squirm. — Richard B
Yep. The difference in science is not in the basic physiology. At least you now agree with me here.As does the indirect realist. — Michael
Scratch out "mind-independent" and you have it....but the direct realist argues that there's a much more substantial relationship; one in which information about themind-independentnature of the ship is given in the sensory experience... — Michael
Are you willing to claim that the character of experience is not determined, at least partly, by things in the world? Surely not."the phenomenal character of experience is determined, at least partly, by the direct presentation of ordinary objects" — Michael
Percepts, in such an account, would be some stage in various layers of Markov blankets, just one of the levels of the internal states within the nested, hierarchical Markov blanket architecture. The perception is inside the Markov blanket, but not disconnected from what it outside. Crucially, The system does not “see” the percept; rather, the system sees by being in that state.We don’t really know what mental phenomena — or as scientists of perception call them, percepts — are, — Michael
I believe most indirect realists believe — Michael
They're not intenced as such. Your claim concerned what "most indirect realists believe", but there is no evidence on which this might be based.Indirect realism is still realism, so I don’t understand the relevance of those references. — Michael
:rofl:China's general influence in South America? — jorndoe
Why should we think this covers all the possibilities?Mental phenomena are either reducible to neurological phenomena or are emergent. — Michael
ButI am interested in your opinion on the following and how you would think Kripke would reply. — Richard B
I'll try explaining this again.Kripke pointed out that if water is H₂O, if they are indeed identical, then necessarily, they are identical. If they are the very same, then they are the very same in every possible world. — Banno
This is better - we are getting closer to the presumptions underpinning this picture of the world.Do mental phenomena exist, and if so are its properties the mind-independent properties of things like apples (or do they in some sense resemble them)? If mental phenomena do exist and if its properties do not resemble the mind-independent properties of things like apples then indirect realists are correct and there is an epistemological problem of perception. — Michael
There are legitimate phenomenological and epistemological differences between direct and indirect realism that can only be addressed by a scientific study of the world and perception, and that cannot be deflated by some semantic argument that "X is red" means "X causes such-and-such an experience". — Michael
we know from observation that metals expland more than wood, for example does with heat, and wood more than metals with moisture. — Janus
My guess is that he has them lined up already, since he has stated an agreement publicly. — Questioner
Yep. It helps to talk of the other senses - a suggestion from Austin. We already used the taste of sugar being sweet - the contact is pretty direct there. Touch provides an alternate example, rough against smooth.A lot of the foofaraw here seems to hinge on "in contact." — J
Yeah, it does. In order to determine that something has expanded on heating, we have to compare it to something else, and assuming that the something else has remained unchanged. Nor was it wrong for Martin Horký and Francesco Sizzi to ask if telescopes distorted the images of Saturn and Jupiter. The acceptance of these observations came along with the development of the theory of optics. Aboriginal people embed their understanding of the world in stories in order to make sense of them, in much the same way as Aristotle and Newton. Calling one set of stories "theory" and the other "myth" is pretty arbitrary.The analogue thermometer is based on the observation that things expand when heated, an observation which does not rely upon a theory of the nature of heat. — Janus
There doesn't seem to be any plan for exactly how they are going to "run" Venezuela. — Questioner
Yes, you did. I marked "what judgment itself presupposes" specifically because of the central place you give it.I’ve already addressed this point several times. — Esse Quam Videri
and your concern with:...judgment presupposes answerability to how things are and the intelligibility of error. — Esse Quam Videri
So let's set the trilemma up again, using the changed language you are here adopting: we suppose that if someone judges something to be true then they presupposes answerability to how things are and the intelligibility of error, in order to so judge; but then they must either again explain that presupposes answerability to how things are and the intelligibility of error; or they must take them as fundamental; or they must rely on circularity, where judgements form the conditions for themselves.an infinite regress of conditions— — Esse Quam Videri
I would instead point out that the example shows that the practice counts as making the judgement. Your reading this thread counts as "EQV is reading this tread" being true.Practice determines what would count as being right, but it does not (and cannot) itself make a judgment right. — Esse Quam Videri
Perhaps we agree that there are things that are taken as granted in order to enact an inquiry. But were you say these things exist of necessity, I point out that they are instead aspects of our practice....reflectively identifying what inquiry itself presupposes in order to function as inquiry. — Esse Quam Videri
is not quite right, since the underivable truths are true within the system. Truth is a part of the things we do with language.Notably, this presupposes a notion of truth that is not exhausted by system-relative coherence — Esse Quam Videri
Cheers. You are of course under no obligation to respond to my posts.I think we have reached the point in the discussion where further clarification is unlikely to be productive. Thank you for the interesting discussion. — Esse Quam Videri
I think the science clearly shows that colour, taste, smell, etc. are the product of our biology, causally determined by but very different to the objective nature (e.g. the chemical composition) of apples and ice creams. — Michael
Yes, yours did that, which is what my argument about the age of consent demonstrates. — BenMcLean
When you see a boat, it' a boat that you see. If what you see is not a boat - if it is an illusion of an hallucination - then by that very fact what you see is not a boat.What's in dispute is what's perceived - the world itself or mental states — Clarendon
Picking up on these observations: By starting with the idea of "looking at a ship", we can be misled into believing that to perceive a ship is always to do so under that description.. A child has to learn, quite literally, to look at a ship -- to learn what to look for, how to recognize one, what the fuzzy cases are. Direct perception would instead be something like "bare colors and textures" -- a very unnatural thing for the human species to experience, past infancy. I think that to defend direct realism, you have to argue that those unmediated (?) experiences are what we perceive, full stop. — J
Does it? Try setting that out. Sometimes it's 22ºC by the thermometer and feels cold; sometimes, too hot. The water freezes at about 0ºC, but only more or less - and boils at a bit under 100ºC.......a thermometer works reliably as attested by experience — Janus
There's a lot going on in that. Why should we accept it?To perceive something is to be in unmediated contact with it. — Clarendon
Maybe not in those terms: Survey Results: Metaontology: heavyweight realism, anti-realism, or deflationary realism?I think most contemporary philosophers will want to describe themselves as direct realists of one sort or another. — Clarendon
The observational knowledge of science is of course true. The hypotheses and theories as to how the processes observed work are defeasible models. They cannot be definitively demonstrated to be true. — Janus
So what I'm looking for in your response is "what judgment itself presupposes" so that a judgement can be true or false.The move to the unconditioned is not made by upgrading epistemic necessity into modal necessity, It is made by reflecting on what judgment itself presupposes in order to be truth-apt at all. — Esse Quam Videri
Is this concerning the branch of Agrippa’s trilemma that results in an infinite regress? Ok.If our operating notion of reality were such that reality is conditioned all the way down, then for any claim, further conditions could always be demanded such that no fact, state of affairs or claim could ever be counted as truly settled. — Esse Quam Videri
So your trilemma is set up like this, using the language you are adopting: we suppose that if someone judges something to be true then they are able to state the conditions under which they so judge; but then they must either again explain their judgement as to the truth of those conditions; or they must take them as fundamental; or they must rely on circularity, where judgements form the conditions for themselves.This is not the same as saying merely that we are finite and fallible, or that inquiry is ongoing. It implies something much stronger - namely, that there is no fact of the matter that could ever settle a judgment as finally correct, because any purported settlement is always relative to a context, stage or set of conditions that could always, in principle, be revised. — Esse Quam Videri
So now you have two notions of truth, ordinary and robust. Ordinary truth is "what's best so far" and robust truth is "how things really are". You worry is about losing the ability to tell which we have.One might respond “Okay, maybe ‘final truth’ disappears, but why does ordinary truth go with it?”. The robust notion of truth implicit in every act of judgment is not just “what we currently accept”, “what fits in a framework” or “what is best so far”. Implicit within the robust notion of truth is the idea that “this is how things really are, and denying it misrepresents reality”. But if reality itself is understood to be such that it can never settle anything without remainder, then the very notion of “misrepresenting reality” has no determinate content, and the robust notion of truth itself becomes indistinguishable from provisional endorsement. — Esse Quam Videri
So now you have along side the two notion of truth, two notions of explanation, one of which is "authentic" in that it commits one to saying how things are "unconditionally".But this is not an apt characterization of what we are doing when we engage in authentic inquiry. The way we talk about such things betrays the fact that the very act of judging each other's claims to be true or false carries within it an implicit commitment to robust notions of truth and reality and, thus, to reality itself being unconditioned (and intelligible) without remainder. — Esse Quam Videri
