You expect that Wittgenstein's philosophy should enable us to prevent deception? — Luke
Haha, that's funny. Philosophy has a long history of rooting out and exposing deception. Socrates, Plato, and Aristotle all addressed sophistry as a significant problem inherent within the educational institutions of the day. Then came skepticism. Now we have all sorts of modern attacks on deception, starting with Descartes. I believe that a philosophy with no principles for the recognition of deception, to distinguish real knowledge from fake knowledge, is useless, and not actually philosophy. But many, perhaps you, believe that philosophy is useless.
1: For the person feeling a pain, the pain sensations they have represent some other thing or process. — jkg20
I believe "process" is the better word here. And this is important to the topic of the thread, "idealism" because most forms of idealism represent ideas as static passive things. This is the problem Plato identified in Pythagorean idealism with the theory of participation, an inherent problem which Aristotle greatly expanded on to decisively refute that form of idealism. In this idealism,the thing being participated in, the idea is necessarily passive. That's a problem in metaphysics, which leads to the accusation by monists, that eternal ideas cannot have any causal affect in the world.
Also, as I tried to explain earlier, I would not call the sensation a representation. I think that this is a mistake which we get from Kant, who describes sensations as representations. From the philosophy of semiotics we can see that biological activities can be described in terms of "signs". The significance of a sign is described in terms of meaning, not in terms of representation. We can get some insight into this difference through Wittgenstein's two ways of describing meaning, as representation in the Tractatus, and as use in PI. We can understand that any sign, such as a word for example, has significance or meaning, which might or might not be accurately called a representation.
So, I first look at the sensation as a product, created by the biological systems. The biological systems use semiosis to create the sensation. Since we cannot conclude that the significance of a sign is necessarily as a representation, we cannot conclude that a sensation is a representation.
2: For that person to really be in pain, the pain sensation must correctly represent the presence or occurrence of that other thing. — jkg20
If my explanation of #1 wasn't complicated enough, this is where things start to get complex. For a person to be really "in pain", we need a definition of what constitutes "pain". So now we have to turn to the public use of language, as "pain" is a word in the public communication system, and we need to look for the so-called objective definition of pain. If we were staying within the private realm, I could have a sensation, and mark it as S, and every time I had a similar sensation I'd call it S. If my judgement was good, I'd have consistency, in what S refers to. But S would probably refer to something very specific, a head ache, a sore thumb, or any other specific sensation, like when I call another person or animal by a particular name. When we go to the public sphere however, we allow our words to have extremely generalized and vague meaning, because the application, usage, in communication rather than naming particular sensations, is extremely varied. If "pain" could only refer to a sore thumb, then we'd need another word for a sore finger, and sore toes, legs, hands, etc. So "pain" being a public word in the domain of communication, rather than a private sign for a person's own internal usage, has a significantly vague meaning.
Furthermore, we now have the issue of the internal process which is being referred to with the word "pain". To judge whether a person is really in pain or not, we are looking on as an external observer, with an understanding of the public word, "pain". So we would be judging whether the person's sensation corresponds with "pain" as defined. Therefore in judging whether the person is really experiencing pain, and what we would call "real pain", we do not even approach this internal relation between the sensation, and the thing which the sensation is symbolic of. To put this in Kant's terms, we are judging the phenomena, the sensation, we are not getting to the noumena. But I do not agree with Kant, that we cannot get to the noumena, we actually do get to them through the private experience of reflection, and apprehension of the intelligible objects themselves, directly as intelligible objects, as described by Plato.
But here we are faced with the incompatibility. The intelligible object presents itself to us in the form of a symbol, a sign, which is a static thing. The sign though symbolizes something active, a process. The true intelligible object is active. So we have a gap to bridge. The true thing-itself is the process which is symbolized by the sign. Idealism assumes a static "idea", and asserts that this static thing is the true intelligible object, which in its own interpretations it is, but this static thing can only be a sign, or symbol of the underlying process (a "representation" of it, which is not even properly called a representation), and that process remains within the realm of the unintelligible for idealism. But actually we do have access to this process, to understand it, through understanding this relation between the sign and the process, which people call "representation", but more properly known as significance or meaning, because a static thing cannot correctly represent an activity.
3: Where there is representation there is the possibility of misrepresentation. — jkg20
Yes, and the problem is far deeper than that simple representation you offer. What is called a "representation" is most likely not even a representation at all. Therefore we cannot start with the assumption of representation. This is the problem which Socrates demonstrate way back in Plato's Theaetetus, and Wittgenstein demonstrated in the Tractatus. If we start with the assumption that knowledge consists of representation, then knowledge must be correct, or "true" representation. Now we have Socrates' problem of how false representation is excluded from knowledge. It appears like it cannot be done. Now knowledge consists of both true and false representation, but that makes no sense to say that false representation could be knowledge. Therefore we ought to recognize that describing knowledge as representation is a mistake.
The concept of "description" becomes very important now. So we need to understand the difference between a description and a representation. We can use mathematics to make a model, a representation for example, but that representation is based on a description, it represents what has been described (observed). Now we need to proceed toward understanding what constitutes a description, an observation. Notice that we need to make available the apt terms, and this process of making them available is more a process of defining rather than representing. This is where Wittgenstein appears to stumble, by assuming that language in general has inherent limits, making some things impossible to understand, rather than allowing that it is limitless, and we only apply boundaries as necessary. However, to give Wittgenstein credit, he distinctly describes the latter in some passages, but he seems to always revert to the former. We can see in mathematics for example, the concept of infinite is intended to allow that anything can be counted.
4: So a person could be having pain sensations, but not actually be in pain because those sensations are incorrectly representing the presence of that other thing. — jkg20
The problem here is the double representation, what Plato called narrative, which he warned us against. "Pain" here is the public word, defined by public use. So in reality it refers to having pain sensations. If the person has pain sensations, then it is real pain. We could even allow a further layer of representation and say it refers to pain behaviour, like Luke suggests. But each layer of representation gets us further from the truth. If we go the other way now, to the deeper internal level of what the sensation is symbolic of within the person, we cannot properly use that term "pain" here, this would create equivocation and the potential for the appearance of contradiction.
That's what "the beetle in the box" analogy shows, the inclination to equivocate in this respect. In the private language, the person notes the sensation as S. But the sensation noted as S, is symbolic of something further, and this is called the "beetle". So "beetle" here refers to that further thing which is indicated by a particular sensation. In the public language there is also "beetle". But "beetle" here in the public language refers to a person's sensation. Notice that "beetle" now has two completely different validations. Do you see that if the person is feeling the sensation of pain, the presence of "the beetle", but the sensations are incorrectly representing the presence of that thing, the person is truly in the presence of "the beetle" according to the public usage, but not in the presence of "the beetle" according to the private sense, in which the sensation is supposed to represent that deeper thing.
