I have to say, this is entirely intelligible to me and (linguistically) solves a problem I've had for some time - there are clearly non-physical objects of experience. — AmadeusD
…..“that which is real its existence is given; a real thing cannot not exist (necessity)”
-Mww
Is this “real thing” the object which was given to the senses? — "Bob
Why would it be necessary that a cup exists because we experience a cup? — Bob Ross
I don’t see the necessity you are talking about here. — Bob Ross
The way we sense is prestructured (….) in a certain way to react to stimuli — Bob Ross
Technically, though, the a priori structure of sensibility itself (…) resides in reason, insofar as the matter of sensation is transcendental.
I don’t see how it would be. Our neurons send the sensations to the brain; not vice-versa. — Bob Ross
I think we have good reasons to believe, e.g., that electrons exist. — Bob Ross
Why not, though, just use ‘real’ and ‘existent’ interchangeably and note, instead, that not all the models and concepts we deploy to explain experience necessarily exist in reality (i.e., are not real)? — Bob Ross
If we can't sense it, can’t indicating an impossibility, how would we know it exists?
Through empirical tests with the help of self-reflective reason. — Bob Ross
That’s an equivocation. (1) I wasn’t asking just about empirical knowledge…… — Bob Ross
your using the term ‘empirical’ to only strictly refer to what is sensed—that’s not what it usually means. — Bob Ross
I know that my car is in my garage even though no one is sensing it. For you, this is invalid knowledge. — Bob Ross
……representing objects in space is a priori knowledge; which I thought you were denying because it is intuition. — Bob Ross
We are getting there — Bob Ross
I think we have good reasons to believe, e.g., that electrons exist. — Bob Ross
I am not following how we only know through contradictions (between our experiences and reality). I can imagine perfectly fine a person who infers correctly, without contradiction, that their conscious experience is representational; and then proceeds to correctly identify that there must be a thing-in-itself which excites the senses which, in turn, begins the process to construct the conscious experience which they are having. — Bob Ross
Can you cite something we could say is knowledge that did not require any experience to gain it?
The most basic example that comes to mind is mathematical knowledge. Your brain necessarily has to already know how to perform math to construct your conscious experience; and this is why mathematical propositions, in geometry, are applicable and accurate for experience: the axioms of geometry reside a priori in our brains — Bob Ross
Mathematical propositions are valid in virtue of being grounded in how our brains cognize; and they are only valid for human experience. They are true, justified, beliefs about experience—not reality. — Bob Ross
Perhaps that’s where the confusion was: the a priori knowledge we have is not knowledge about reality, but about how we cognize it. — Bob Ross
So what is a flower apart from any observation
I would say that we merely say that there is some thing which is exciting our senses, and of which we represent as what we normally perceive as a flower. — Bob Ross
And that's all the 'thing in itself' is. Its an unknowable outside of the mind existence.
Agreed; but that’s not a purely abstract thing, then. It is a concrete—unknown. — Bob Ross
"Objects of experience" or 'aspects of understanding or judgement'? Perhaps an example or two would be helpful. — Janus
…..“that which is real its existence is given; a real thing cannot not exist (necessity)”
-Mww
Is this “real thing” the object which was given to the senses? — "Bob
Yes.
It is necessary that some thing exists, which becomes the experience of, in this case, cup.
You’re explicitly demanding neurons send the feeling of a mosquito bite, when the science legislating neural activity will only permit neurons to send quantitative electrochemical signals.
Errrr….wha??? We don’t care what neurons do when talking about speculative transcendental architecture.
I think we have good reasons to believe, e.g., that electrons exist. — Bob Ross
That was never a contention; believing in a thing is very far from knowledge of it.
The real and the existent are pretty much already interchangeable
Because you’re talking sensing, the only knowledge you’re going to get from it, if you get any at all, is empirical.
…
That’s all it’s ever meant to me. I use empirical to describe a kind of knowledge, rather than a posteriori, which prescribes its ground or source.
What else does it refer to for you?
For me it’s unjustified to call it knowledge.
What do you really know, with respect to the car itself, when somebody tells you he put your car in the garage?
Representing objects in space is a priori; it is intuition, which isn’t knowledge.
Lets break this down.
This is why in my knowledge theory I broke down what knowledge is into two camps.
For example, we applicably know math through 'base 10'. But math can be in any base. Base 2, or binary, is the math we use for logic circuits.
The ability to think is not generally prescribed as 'knowledge'. Just like the ability to 'move my limbs' doesn't mean I know 'how to move them to walk'.
It is purely an abstract thing that cannot be applicably known.
"The thing in itself" is a space alien
Give me an example of where something is real but does not exist (if applicable); and where something exists but is not real (if applicable). — Bob Ross
How, then, do you distinguish from a fake thing which is does not exist, and one which does (but of which both are not given to the senses)? — Bob Ross
….a ‘fake [viz., non-real] thing’…. — Bob Ross
It is necessary that some thing exists, which becomes the experience of, in this case, cup.
-Mww
Agreed; but you are also saying that this necessary thing that is given not only exists but is real; which implies that a thing which exists but is not given is not real. — Bob Ross
the sensibility must have some pre-structured way of sensing before anything is intuited or cognized—i.e., without reason. — Bob Ross
I have no clue why we would assume that most, if not everything, can be sensed by our sensibility—viz., given to the senses. — Bob Ross
The real and the existent are pretty much already interchangeable….
-Mww
Not at all under your view! The real is only a subset of existent things which are given or (perhaps) possibly given to the senses. I — Bob Ross
I think you still see my point: we can reason about our experience to know things which are not directly perceived. — Bob Ross
What do you really know, with respect to the car itself, when somebody tells you he put your car in the garage?
I know it, because I have a true, justified belief. E.g., I just drove it into the garage, went inside, and now am being asked “is the car in the garage?” — Bob Ross
What makes something a priori and knowledge, then? — Bob Ross
there is just a pre-structure for doing so, and that propositions that we (qua agents) know a priori because of that pre-structure (e.g., “all bodies are extended”)? I can get on board with that. — Bob Ross
They [electrons] only have a tendency to exist. We know they don't have any determinate existence until they're measured. That is an implication of Heisenberg's uncertainty principle. We also know that sub-atomic phenomena can behave as both waves and particles, and so are not really either one or the other, as those two forms of existence are incommensurable. — Wayfarer
I am not familiar enough with quantum physics to comment back: I don't understand how to reconcile qp with practical life---it seems incoherent. — Bob Ross
All you are describing here is a category error, where some information is a product of our brain (Frodo and Mordor), and assumed to point to something outside of our brain as opposed to a product of some other process (how money is made). Counterfeit money is real money when you buy things with it. It is only when someone is able to make the distinction (measured) and no longer accepts it does it become counterfeit (if we are to apply the same line of thinking Wayfarer described about electrons).Something exists if it is in the domain of discourse. Frodo walked into Mordor, therefore there is something that walked into Mordor.
Something is real in contrast to things that are not real - is it real money, or counterfeit? Is that really water, or a mirage? Is that a real argument, or just a vague rant?
Other uses are parasitic. — Banno
Then a thing-in-itself is not a concept which is purely logical—that was my only point on this note. It is referencing something concrete. Mww is denying this, and I thought so were you. — Bob Ross
I disagree. Counterfeit money is counterfeit from the get go, having not been manufactured in a way that grants it legitimacy.Counterfeit money is real money when you buy things with it. It is only when someone is able to make the distinction (measured) and no longer accepts it does it become counterfeit — Harry Hindu
There's your problem, right there.(if we are to apply the same line of thinking Wayfarer described about electrons) — Harry Hindu
None of this explains what it means to be real. What property of counterfeit money, mirages and arguments are we are comparing exactly if not the causes or circumstances that are necessary for them to exist?Something is real in contrast to things that are not real - is it real money, or counterfeit? Is that really water, or a mirage? Is that a real argument, or just a vague rant? — Banno
Exactly. Counterfeit has a determinate existence prior to being measured and it is in measuring (comparing the appearance of real money to counterfeit money) that one knows it is really counterfeit money.I disagree. Counterfeit money is counterfeit from the get go, having not been manufactured in a way that grants it legitimacy. — Banno
What exists is what you can meaningfully encounter.
As to things that exist but aren't real - well, fictional characters would fit the bill. We will both know who Bugs Bunny and Sherlock Holmes are, so we have a common reference point, but they're not real. Nowadays we're constantly bombarded by unreal imagery.
For that of which I merely think, which would be that thing which for me cannot be real because I have no intuition of it, there’s no difference in my internal treatment of a real and a non-real thing, insofar as the only representation for either of them is a conception or a series of conceptions, in accordance with a rule.
The real, then, is the set….not a subset…..of existent things given to the senses, which says nothing at all about things not given to the senses, and for which, therefore, the real has no ground for consideration.
Hence to reason about experience, and to know things not directly perceived from that reasoning alone, is a posteriori reasoning.
Your answer doesn’t respect the question. Trust me, it’s pertinent, at least to the theme we’re immersed in up to our eyeballs in right now.
The pre-structure here, re” “all bodies are extended”, is an empirical principle, in that it applies to things alone, and is only susceptible to natural proofs, but our knowledge of this arises through separate pure principles of universality and necessity, in that without these pure principles, the empirical principles cannot have natural proofs at all, from which follows the possibility some bodies are not extended, and we are presented with a contradiction and our knowledge of empirical things becomes forever undeterminable.
Thus, a purely logical concept can still have reference to something concrete, even if cognition of something concrete belonging to that conception, is not determinable from such mere reference alone.
Space, a purely logical concept if there ever was one, would be useless if it didn’t refer to concrete things, so……there ya go.
So, no, I do not deny the thing-in-itself references something concrete, while maintaining the thing-in-itself is a purely logical conception.
The only issue I have is with your semantics: I think you are using ‘existence’ as if it is reserved for only things which exist materially (or perhaps physically). — Bob Ross
What you are doing is conflating this with colloquial language where one would mean by “is this fictional character real?” — Bob Ross
C.S. Peirce’s distinction between reality and existence is rooted in his pragmatic philosophy and his interest in semiotics. For Peirce, reality refers to that which is independent of individual thought, meaning it would still be true regardless of what anyone believes. In contrast, existence pertains to something that actively interacts with other things in time and space, having a physical presence. Thus, while something real may exist, reality encompasses a broader domain of truths, including abstract concepts like laws of nature or mathematical objects, which don’t exist in a material sense but are still real because they hold independently of personal opinion.
Peirce's scholastic realism was grounded in the form of medieval scholasticism which argued that universals (such as concepts like 'redness' or 'beauty') are real, though they don’t exist as independent objects. Peirce adopted this view, opposing nominalism, which claims that universals are merely names we use to group things together. For Peirce, universals are real because they represent tendencies or patterns in nature that guide how things behave. His realism is grounded in his belief that the regularities of the world, such as the laws of logic or nature, are not arbitrary constructs of the human mind but are real features of the universe. Thus, scholastic realism for Peirce upholds the idea that general principles and categories have a real basis in the fabric of reality, not just in human thought.
//
Peirce understood nominalism in the broad anti-realist sense, usually attributed to William of Ockham, as the view that reality consists exclusively of concrete particulars and that universality and generality have to do only with names and their significations. This view relegates properties, abstract entities, kinds, relations, laws of nature, and so on, to a conceptual existence at most. Peirce believed nominalism (including what he referred to as "the daughters of nominalism": sensationalism, phenomenalism, individualism, and materialism) to be seriously flawed and a great threat to the advancement of science and civilization 1.
Characterized by forms, reality had an intrinsic intelligibility, not just in each of its parts but as a whole. With forms as causes, there are interconnections between different parts of an intelligible world, indeed there are overlapping matrices of intelligibility in the world, making possible an ascent from the more particular, posterior, and mundane to the more universal, primary, and noble.
In short, the appeal to forms or natures does not just help account for the possibility of trustworthy access to facts, it makes possible a notion of wisdom, traditionally conceived as an ordering grasp of reality. Preoccupied with overcoming Cartesian skepticism, it often seems as if philosophy’s highest aspiration is merely to secure some veridical cognitive events. Rarely sought is a more robust goal: an authoritative and life-altering wisdom. — Joshua Hochschild, What's Wrong With Ockham?
Why isn’t it real for you if you have no intuition of it? — Bob Ross
Your car in the garage isn’t real right now, even though you have every reason to believe it is there, because you can’t currently sense it? — Bob Ross
This is incoherent though: you are saying that there could be a thing which is in reality but is not (i.e., does not exist because it cannot be given to the senses). — Bob Ross
You are playing around with ‘being’ in ways that are not fundamental enough — Bob Ross
….to know things (…) from that reasoning alone, is a posteriori reasoning.
-Mww
Then, you are claiming that all a posteriori knowledge….. — Bob Ross
…..since only directly perceived things exist. — Bob Ross
Your answer doesn’t respect the question.
-Mww
How so? Isn’t it epistemically justification enough to claim that the car is in the garage (even though I don’t see it right now) because I had just drove it in there 5 seconds ago? — Bob Ross
“Space, a purely logical concept if there ever was one, would be useless if it didn’t refer to concrete things….”
-Mww
Noooo. The concept of space refers to extension….. — Bob Ross
then I agree. — Bob Ross
I understand you will probably reject this, because of the overwhemingly nominalist cast of modern culture and philosophy. But that's OK, and thanks for reading.
Things that exist as phenomena. And recall, 'phenomena' means 'what appears'.
To me, to take a ‘realist’ account, in the medieval sense, is to necessarily posit that the a priori ways by which we experience is a 1:1 mirror of the forms of the universe itself; — Bob Ross
So what? There are many attributes and properties of things that do not exist independently of the thing itself. We don't say that the ripeness of this apple isn't real because it can't exist independently of this apple. You seem to be making an unwarranted special case for minds.What is real is what is denoted by the symbol, and that is not something that exists in the sense of being real independently of any mind (as only a mind can grasp number.) — Wayfarer
