Re: [Fis] Data - Reflection - Information
Against "meaning" I think that there is a danger of allowing our anthropocentrism to bias the discussion. I worry that the term 'meaning' carries too much of a linguistic bias. By this I mean that it is too attractive to use language as our archtypical model when we talk about information. Language is rather the special case, the most unusual communicative adaptation to ever have evolved, and one that grows out of and depends on informationa/semiotic capacities shared with other species and with biology in general. So I am happy to see efforts to bring in topics like music or natural signs like thunderstorms and would also want to cast the net well beyond humans to include animal calls, scent trails, and molecular signaling by hormones. And it is why I am more attracted to Peirce and worried about the use of Saussurean concepts. Words and sentences can indeed provide meanings (as in Frege's Sinn - "sense" - "intension") and may also provide reference (Frege's Bedeutung - "reference" - "extension"), but I think that it is important to recognize that not all signs fit this model. Moreover, A sneeze is often interpreted as evidence about someone's state of health, and a clap of thunder may indicate an approaching storm. These can also be interpreted differently by my dog, but it is still information about something, even though I would not say that they mean something to that interpreter. Both of these phenomena can be said to provide reference to something other than that sound itself, but when we use such phrases as "it means you have a cold" or "that means that a storm is approaching" we are using the term "means" somewhat metaphorically (most often in place of the more accurate term "indicates"). And it is even more of a stretch to use this term with respect to pictures or diagrams. So no one would say the a specific feature like the ears in a caricatured face mean something. Though if the drawing is employed in a political cartoon e.g. with exaggerated ears and the whole cartoon is assigned a meaning then perhaps the exaggeration of this feature may become meaningful. And yet we would probably agree that every line of the drawing provides information contributing to that meaning. So basically, I am advocating an effort to broaden our discussions and recognize that the term information applies in diverse ways to many different contexts. And because of this it is important to indicate the framing, whether physical, formal, biological, phenomenological, linguistic, etc. For this reason, as I have suggested before, I would love to have a conversation in which we try to agree about which different uses of the information concept are appropriate for which contexts. The classic syntax-semantics-pragmatics distinction introduced by Charles Morris has often been cited in this respect, though it too is in my opinion too limited to the linguistic paradigm, and may be misleading when applied more broadly. I have suggested a parallel, less linguistic (and nested in Stan's subsumption sense) way of making the division: i.e. into intrinsic, referential, and normative analyses/properties of information. Thus you can analyze intrinsic properties of an informing medium [e.g. Shannon etc etc] irrespective of these other properties, but can't make sense of referential properties [e.g. what something is about, conveys] without considering intrinsic sign vehicle properties, and can't deal with normative properties [e.g. use value, contribution to function, significance, accuracy, truth] without also considering referential properties [e.g. what it is about]. In this respect, I am also in agreement with those who have pointed out that whenever we consider referential and normative properties we must also recognize that these are not intrinsic and are interpretation-relative. Nevertheless, these are legitimate and not merely subjective or nonscientific properties, just not physically intrinsic. I am sympathetic with those among us who want to restrict analysis to intrinsic properties alone, and who defend the unimpeachable value that we have derived from the formal foundations that Shannon's original analysis initiated, but this should not be used to deny the legitimacy of attempting to develop a more general theory of information that also attempts to discover formal principles underlying these higher level properties implicit in the concept. I take this to be the intent behind Pedro's list. And I think it would be worth asking for each of his points: Which information paradigm within this hoierarchy does it assume? — Terry ___ Fis mailing list Fis@listas.unizar.es http://listas.unizar.es/cgi-bin/mailman/listinfo/fis
Re: [Fis] Data - Reflection - Information
Hi FISers, Recent discussions on information on this list reminds me of one of the main principles of signs advanced by Ferdinand de Saussure (1859-1913) -- the arbitrariness of linguistic signs. In contrast, Peirce (1839-1914), a chemist-turned-logician-philosopher, seems to have succeeded in capturing the universal features of all signs, however fleeting, both linguistic and otherwise. The power and utility of the Peircean definition of signs can be illustrated by applying his triadic definition of signs to the term, 'information', veiwed as a sign (having an arbitrariy meaning, according to Saussure). My impression is that all the varied defintions of information discussed on this list (which supports the Saussre's principle of the arbitrariness of signs) can be organized using the ITR (Irreducible Triadic Relation) diagram embodying the Peircean principle of semiotics. This is done in Figure 1 below, using the definition of 'information' that Professor Zhong recently provided as an example. As you can see, the ITR template has 6 place-holders, 3 nodes and 3 arrows, which can be populatedf by more than one set of concepts or terms, as long as the terms or concepts are consistent with one another and obeys well-established laws of physics and logic. f g Object --> Sign --> Interpretant (Object Information) (Data) (Perceived Information) | ^ | | | | |__| h f = natural process (or information production) g = mental process or computing (or information interpretation) h = correspondence (or information flow) Object = Something referred to by a sign Sign = Something that stands to someone for something other than itself in some context. Also called ‘representamen’ Interpretant = The effect a sign has on the mind (or state) of the interpreter (human or non-human) Figure 1. A suggested definition of ‘information’ based on the triadic definition of the sign proposed by Peirce (1839-1914). The symbol, A --- > B, reads as "A determines B', 'A leads to B', ' A is presupposed by B', 'B is supervened on A' (http://www.iep.utm.edu/superven), etc. With all the best.

For this goal, belowI shall remember shortly main ideas presented this week.Citations:Stanley N Salthe: “The simple answer to your question about data is to note the word'sderivation from Latin Datum, which can be compared with Factum.”Y. X. Zhong:“It is not difficult to accept that there are two concepts of information,related and also different to each other. The first one is the informationpresented by the objects existed in environment before the subject'sperceiving and the second one is the information perceived and understoodby the subject. The first one can be termed the object information and thesecond one the perceived information. The latter is perceived by thesubject from the former.The object information is just the object's "state of the object and thepattern with which the state varies". No meaning and no utility at thestage.The perceived information is the information, perceive by the subject fromthe object information. So, it should have the form component of theobject (syntactic information), the meaning component of the object(semantic information), and the utility component of the object withrespect to the subject's goal (pragmatic information). Only at this stage,the "meaning" comes out.”Karl Javorszky:“Data is that what we see by using the eyes. Information is that what wedo not see by using the eyes, but we see by using the brain; because it isthe background to that what we see by using the eyes.Data are the foreground, the text, which are put into a context by theinformation, which is the background. In Wittgenstein terms: Sachverhaltand Zusammenhang (which I translate – unofficially – as facts /data/ andcontext /relationships/)”.Dai Griffiths:“I'm curious about your use of the word 'dualistic'. Dualism usuallysuggests that there are two aspects to a single phenomenon. As I interpretyour post, you are saying that information and meaning are separateconcepts. Otherwise, we are led to inquire into the nature of the unity ofwhich they are both aspects, which gets us back where we started.So I interpret 'dualistic' here to mean 'two concepts that are intertwinedin the emergence of events'. Is this parallel to, for example, atomicstructure and fluid dynamics (perhaps there are better examples)? If so,does that imply a hierarchy (i.e. you can have information withoutmeaning, but not meaning without information)? This makes sense to me,though it is not what I usually associate with the word 'dualistic'.”Guy A Hoelzer:“If you start by explicitly stating that you are using the semantic notionof information at the start, I would agree whole heartedly with your post.I claim that physical information is general, while semantic informationis merely a subset of physical information. Semantic information iscomposed of kinds of physical contrasts to which symbolic meaning has
