Sign Relations • Examples • https://inquiryintoinquiry.com/2024/02/10/sign-relations-examples-b/ All, Soon after I made my third foray into grad school, this time in Systems Engineering, I was trying to explain sign relations to my advisor and he — being the very model of a modern systems engineer — asked me to give a concrete example of a sign relation, as simple as possible without being trivial. After much cudgeling of the grey matter I came up with a pair of examples which had the added benefit of bearing instructive relationships to each other. Despite their simplicity, the examples to follow have subtleties of their own and their careful treatment serves to illustrate important issues in the general theory of signs. Imagine a discussion between two people, Ann and Bob, and attend only to the aspects of their interpretive practice involving the use of the following nouns and pronouns. • “Ann”, “Bob”, “I”, “you”. • The “object domain” of their discussion is the set of two people {Ann, Bob}. • The “sign domain” of their discussion is the set of four signs {“Ann”, “Bob”, “I”, “you”}. Ann and Bob are not only the passive objects of linguistic references but also the active interpreters of the language they use. The “system of interpretation” associated with each language user can be represented in the form of an individual three‑place relation known as the “sign relation” of that interpreter. In terms of its set‑theoretic extension, a sign relation L is a subset of a cartesian product O × S × I. The three sets O, S, I are known as the “object domain”, the “sign domain”, and the “interpretant domain”, respectively, of the sign relation L ⊆ O × S × I. Broadly speaking, the three domains of a sign relation may be any sets at all but the types of sign relations contemplated in formal settings are usually constrained to having I ⊆ S. In those cases it becomes convenient to lump signs and interpretants together in a single class called the “sign system” or the “syntactic domain”. In the forthcoming examples S and I are identical as sets, so the same elements manifest themselves in two different roles of the sign relations in question. When it becomes necessary to refer to the whole set of objects and signs in the union of the domains O, S, I for a given sign relation L, we will call this set the “World of L” and write W = W_L = O ∪ S ∪ I. To facilitate an interest in the formal structures of sign relations and to keep notations as simple as possible as the examples become more complicated, it serves to introduce the following general notations. • O = Object Domain • S = Sign Domain • I = Interpretant Domain Introducing a few abbreviations for use in this Example, we have the following data. • O = {Ann, Bob} = {A, B} • S = {“Ann”, “Bob”, “I”, “you”} = {“A”, “B”, “i”, “u”} • I = {“Ann”, “Bob”, “I”, “you”} = {“A”, “B”, “i”, “u”} In the present example, S = I = Syntactic Domain. Tables 1a and 1b show the sign relations associated with the interpreters A and B, respectively. In this arrangement the rows of each Table list the ordered triples of the form (o, s, i) belonging to the corresponding sign relations, L_A, L_B ⊆ O × S × I. Figure. Sign Relation Tables L_A and L_B • https://inquiryintoinquiry.files.wordpress.com/2020/05/sign-relation-twin-t… The Tables codify a rudimentary level of interpretive practice for the agents A and B and provide a basis for formalizing the initial semantics appropriate to their common syntactic domain. Each row of a Table lists an object and two co‑referent signs, together forming an ordered triple (o, s, i) called an “elementary sign relation”, that is, one element of the relation's set‑theoretic extension. Already in this elementary context, there are several meanings which might attach to the project of a formal semiotics, or a formal theory of meaning for signs. In the process of discussing the alternatives, it is useful to introduce a few terms occasionally used in the philosophy of language to point out the needed distinctions. That is the task we'll turn to next.
