In his picturesque illustration of a sign relation, along with his tracing of a corresponding sign process, or ''[[semiosis]]'', Peirce uses the technical term ''representamen'' for his concept of a sign, but the shorter word is precise enough, so long as one recognizes that its meaning in a particular theory of signs is given by a specific definition of what it means to be a sign.

−Logic will here be defined as ''formal semiotic''. A definition of a sign will be given which no more refers to human thought than does the definition of a line as the place which a particle occupies, part by part, during a lapse of time. Namely, a sign is something, ''A'', which brings something, ''B'', its ''interpretant'' sign determined or created by it, into the same sort of correspondence with something, ''C'', its ''object'', as that in which itself stands to ''C''. It is from this definition, together with a definition of ~~"~~formal~~"~~, that I deduce mathematically the principles of logic. I also make a historical review of all the definitions and conceptions of logic, and show, not merely that my definition is no novelty, but that my non-psychological conception of logic has ''virtually'' been quite generally held, though not generally recognized. (C.S. Peirce, NEM 4, ~~20–21~~).

−In the general discussion of diverse theories of signs, the question frequently arises whether signhood is an absolute, essential, indelible, or ''~~[[ontology|~~ontological~~]]~~'' property of a thing, or whether it is a relational, interpretive, and mutable role that a thing can be said to have only within a particular context of relationships.

−Peirce's definition of a ''sign'' defines it in relation to its ''object'' and its ''interpretant sign'', and thus it defines signhood in ''[[logic of relatives|relative terms]]'', by means of a predicate with three places. In this definition, signhood is a role in a [[triadic relation]], a role that a thing bears or plays in a given context of relationships ~~— ~~it is not as an ''absolute'', ''non-relative'' property of a thing-in-itself, one that it possesses independently of all relationships to other things.

Some of the terms that Peirce uses in his definition of a sign may need to be elaborated for the contemporary reader.

Some of the terms that Peirce uses in his definition of a sign may need to be elaborated for the contemporary reader.

−* '''Correspondence'''~~. ~~ From the way that Peirce uses this term throughout his work, it is clear that he means what he elsewhere calls a ~~"~~triple correspondence~~"~~, and thus this is just another way of referring to the whole triadic sign relation itself. In particular, his use of this term should not be taken to imply a dyadic ~~corresponence~~, like the kinds of ~~"~~mirror image~~" ~~correspondence between realities and representations that are bandied about in contemporary controversies about ~~"[[~~correspondence theories of truth~~]]"~~.

−* '''Determination'''~~. ~~ Peirce's concept of determination is broader in several directions than the sense of the word that refers to strictly deterministic causal-temporal processes. First, and especially in this context, he is invoking a more general concept of determination, what is called a ''formal'' or ''informational'' determination, as in saying ~~"~~two points determine a line~~"~~, rather than the more special cases of causal and temporal determinisms. Second, he characteristically allows for what is called ''determination in measure'', that is, an order of determinism that admits a full spectrum of more and less determined relationships.

He was quite interested in matters of psychology and had much of import to say about them. But logic and psychology operate on different planes of study even when they have occasion to view the same data, as logic is a ''[[normative science]]'' where psychology is a ''[[descriptive science]]'', and so they have very different aims, methods, and rationales.

−There is a close relationship between the pragmatic theory of signs and the pragmatic theory of [[inquiry]]. In fact, the correspondence between the two studies exhibits so many congruences and parallels that it is often best to treat them as integral parts of one and the same subject. In a very real sense, inquiry is the process by which sign relations come to be established and continue to evolve. In other words, inquiry, ~~"~~thinking~~" ~~in its best sense, ~~"~~is a term denoting the various ways in which things acquire significance~~" ~~(~~[[~~John Dewey~~]]~~). Thus, there is an active and intricate form of cooperation that needs to be appreciated and maintained between these converging modes of investigation. Its proper character is best understood by realizing that the theory of inquiry is adapted to study the developmental aspects of sign relations, a subject which the theory of signs is specialized to treat from structural and comparative points of view.

The connection that a sign makes to an interpretant is here referred to as its ''connotation''. In the full theory of sign relations, this aspect of meaning includes the links that a sign has to affects, concepts, ideas, impressions, intentions, and the whole realm of an agent's mental states and allied activities, broadly encompassing intellectual associations, emotional impressions, motivational impulses, and real conduct. Taken at the full, in the natural setting of semiotic phenomena, this complex system of references is unlikely ever to find itself mapped in much detail, much less completely formalized, but the tangible warp of its accumulated mass is commonly alluded to as the connotative import of language.

===Ennotation===

===Ennotation===

−The aspect of a sign's meaning that arises from the dyadic relation of its objects to its interpretants has no standard name. If an interpretant is considered to be a sign in its own right, then its independent reference to an object can be taken as belonging to another moment of denotation, but this neglects the mediational character of the whole transaction in which this occurs. Denotation and connotation have to do with dyadic relations in which the sign plays an active role, but here we have to consider a dyadic relation between objects and interpretants that is mediated by the sign from an off-stage position, as it were. As a relation between objects and interpretants that is mediated by a sign, this aspect of meaning may be referred to as the ''ennotation'' of a sign, and the dyadic relation that constitutes the ''ennotative aspect'' of a sign relation ~~'''~~L~~''' ~~may be notated as ~~''~~Enn~~''~~(~~'''~~L~~'''~~).

==Semiotic equivalence relations==

==Semiotic equivalence relations==

−(~~Text ~~in ~~Progress~~)

+A ''semiotic equivalence relation'' (SER) is a special type of equivalence relation that arises in the analysis of sign relations. As a general rule, any equivalence relation is closely associated with a family of equivalence classes that partition the underlying set of elements, frequently called the ''domain'' or ''space'' of the relation. In the case of a SER, the equivalence classes are called ''semiotic equivalence classes'' (SECs) and the partition is called a ''semiotic partition'' (SEP).

+The sign relations <math>L_\mathrm{A}\!</math> and <math>L_\mathrm{B}\!</math> have many interesting properties that are not possessed by sign relations in general. Some of these properties have to do with the relation between signs and their interpretant signs, as reflected in the projections of <math>L_\mathrm{A}\!</math> and <math>L_\mathrm{B}\!</math> on the <math>SI\!</math>-plane, notated as <math>\mathrm{proj}_{SI} L_\mathrm{A}\!</math> and <math>\mathrm{proj}_{SI} L_\mathrm{B},\!</math> respectively. The 2-adic relations on <math>S \times I\!</math> induced by these projections are also referred to as the ''connotative components'' of the corresponding sign relations, notated as <math>\mathrm{Con}(L_\mathrm{A})\!</math> and <math>\mathrm{Con}(L_\mathrm{B}),\!</math> respectively. Tables 6a and 6b show the corresponding connotative components.

+One nice property possessed by the sign relations <math>L_\mathrm{A}\!</math> and <math>L_\mathrm{B}\!</math> is that their connotative components <math>\mathrm{Con}(L_\mathrm{A})\!</math> and <math>\mathrm{Con}(L_\mathrm{B})\!</math> form a pair of equivalence relations on their common syntactic domain <math>S = I.\!</math> It is convenient to refer to such a structure as a ''semiotic equivalence relation'' (SER) since it equates signs that mean the same thing to some interpreter. Each of the SERs, <math>\mathrm{Con}(L_\mathrm{A}), \mathrm{Con}(L_\mathrm{B}) \subseteq S \times I \cong S \times S\!</math> partitions the whole collection of signs into ''semiotic equivalence classes'' (SECs). This makes for a strong form of representation in that the structure of the interpreters' common object domain <math>\{ \mathrm{A}, \mathrm{B} \}\!</math> is reflected or reconstructed, part for part, in the structure of each of their ''semiotic partitions'' (SEPs) of the syntactic domain <math>\{ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \}.\!</math> But it needs to be observed that the semiotic partitions for interpreters <math>\mathrm{A}\!</math> and <math>\mathrm{B}\!</math> are not the same, indeed, they are orthogonal to each other. This makes it difficult to interpret either one of the partitions or equivalence relations on the syntactic domain as corresponding to any sort of objective structure or invariant reality, independent of the individual interpreter's point of view.

+Information about the contrasting patterns of semiotic equivalence induced by the interpreters <math>\mathrm{A}\!</math> and <math>\mathrm{B}\!</math> is summarized in Tables 7a and 7b. The form of these Tables should suffice to explain what is meant by saying that the SEPs for <math>\mathrm{A}\!</math> and <math>\mathrm{B}\!</math> are orthogonal to each other.

+A few items of notation are useful in discussing equivalence relations in general and semiotic equivalence relations in particular.

+As a general consideration, if <math>E\!</math> is an equivalence relation on a set <math>X,\!</math> then every element <math>x\!</math> of <math>X\!</math> belongs to a unique equivalence class under <math>E\!</math> called ''the equivalence class of <math>x\!</math> under <math>E\!</math>''. Convention provides the ''square bracket notation'' for denoting this equivalence class, either in the subscripted form <math>[x]_E\!</math> or in the simpler form <math>[x]\!</math> when the subscript <math>E\!</math> is understood. A statement that the elements <math>x\!</math> and <math>y\!</math> are equivalent under <math>E\!</math> is called an ''equation'' or an ''equivalence'' and may be expressed in any of the following ways:

+{| align="center" style="text-align:center; width:100%"

+|

+<math>\begin{array}{clc}

+(x, y) & \in & E

+\\[4pt]

+x & \in & [y]_E

+\\[4pt]

+y & \in & [x]_E

+\\[4pt]

+[x]_E & = & [y]_E

+\\[4pt]

+x & =_E & y

+\end{array}</math>

+|}

+Thus we have the following definitions:

+{| align="center" style="text-align:center; width:100%"

+|

+<math>\begin{array}{ccc}

+[x]_E & = & \{ y \in X : (x, y) \in E \}

+\\[6pt]

+x =_E y & \Leftrightarrow & (x, y) \in E

+\end{array}</math>

+|}

+In the application to sign relations it is useful to extend the square bracket notation in the following ways. If <math>L\!</math> is a sign relation whose connotative component or syntactic projection <math>L_{SI}\!</math> is an equivalence relation on <math>S = I,\!</math> let <math>[s]_L\!</math> be the equivalence class of <math>s\!</math> under <math>L_{SI}.\!</math> That is to say, <math>[s]_L = [s]_{L_{SI}}.\!</math> A statement that the signs <math>x\!</math> and <math>y\!</math> are equivalent under a semiotic equivalence relation <math>L_{SI}\!</math> is called a ''semiotic equation'' (SEQ) and may be written in either of the following equivalent forms:

+{| align="center" style="text-align:center; width:100%"

+|

+<math>\begin{array}{clc}

+[x]_L & = & [y]_L

+\\[6pt]

+x & =_L & y

+\end{array}</math>

+|}

+In many situations there is one further adaptation of the square bracket notation for semiotic equivalence classes that can be useful. Namely, when there is known to exist a particular triple <math>(o, s, i)\!</math> in a sign relation <math>L,\!</math> it is permissible to let <math>[o]_L\!</math> be defined as <math>[s]_L.\!</math> These modifications are designed to make the notation for semiotic equivalence classes harmonize as well as possible with the frequent use of similar devices for the denotations of signs and expressions.

+The semiotic equivalence relation for interpreter <math>\mathrm{A}\!</math> yields the following semiotic equations:

+{| align="center" style="text-align:center; width:100%"

+|

+<math>\begin{matrix}

+[ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime} ]_{L_\mathrm{A}}

+& = &

+[ {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime} ]_{L_\mathrm{A}}

+\\[6pt]

+[ {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime} ]_{L_\mathrm{A}}

+& = &

+[ {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} ]_{L_\mathrm{A}}

+\end{matrix}</math>

+|}

+or

+{| align="center" style="text-align:center; width:100%"

+|

+<math>\begin{matrix}

+{}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}

+& =_{L_\mathrm{A}} &

+{}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime}

+\\[6pt]

+{}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}

+& =_{L_\mathrm{A}} &

+{}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime}

+\end{matrix}</math>

+|}

+Thus it induces the semiotic partition:

+{| align="center" cellpadding="12" style="text-align:center; width:100%"

+| <math>\{ \{ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime} \}, \{ {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \} \}.\!</math>

+|}

+The semiotic equivalence relation for interpreter <math>\mathrm{B}\!</math> yields the following semiotic equations:

+{| align="center" style="text-align:center; width:100%"

+|

+<math>\begin{matrix}

+[ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime} ]_{L_\mathrm{B}}

+& = &

+[ {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} ]_{L_\mathrm{B}}

+\\[6pt]

+[ {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime} ]_{L_\mathrm{B}}

+& = &

+[ {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime} ]_{L_\mathrm{B}}

+\end{matrix}</math>

+& =_{L_\mathrm{B}} &

+{}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime}

+\end{matrix}</math>

+|}

+Thus it induces the semiotic partition:

+| <math>\{ \{ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \}, \{ {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime} \} \}.\!</math>

+|}

+==Graphical representations==

+The dyadic components of sign relations can be given graph-theoretic representations, as ''digraphs'' (or ''directed graphs''), that provide concise pictures of their structural and potential dynamic properties.

+By way of terminology, a directed edge <math>(x, y)\!</math> is called an ''arc'' from point <math>x\!</math> to point <math>y,\!</math> and a self-loop <math>(x, x)\!</math> is called a ''sling'' at <math>x.\!</math>

+The denotative components <math>\mathrm{Den}(L_\mathrm{A})\!</math> and <math>\mathrm{Den}(L_\mathrm{B})\!</math> can be represented as digraphs on the six points of their common world set <math>W = O \cup S \cup I =\!</math> <math>\{ \mathrm{A}, \mathrm{B}, {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \}.\!</math> The arcs are given as follows:

+{| align="center" cellspacing="6" width="90%"

+|

+<p><math>\mathrm{Den}(L_\mathrm{A})\!</math> has an arc from each point of <math>\{ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime} \}\!</math> to <math>\mathrm{A}\!</math> and an arc from each point of <math>\{ {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \}\!</math> to <math>\mathrm{B}.\!</math></p>

+|-

+|

+<p><math>\mathrm{Den}(L_\mathrm{B})\!</math> has an arc from each point of <math>\{ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \}\!</math> to <math>\mathrm{A}\!</math> and an arc from each point of <math>\{ {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime} \}\!</math> to <math>\mathrm{B}.\!</math></p>

+|}

+<math>\mathrm{Den}(L_\mathrm{A})\!</math> and <math>\mathrm{Den}(L_\mathrm{B})\!</math> can be interpreted as ''transition digraphs'' that chart the succession of steps or the connection of states in a computational process. If the graphs are read this way, the denotational arcs summarize the ''upshots'' of the computations that are involved when the interpreters <math>\mathrm{A}\!</math> and <math>\mathrm{B}\!</math> evaluate the signs in <math>S\!</math> according to their own frames of reference.

+The connotative components <math>\mathrm{Con}(L_\mathrm{A})\!</math> and <math>\mathrm{Con}(L_\mathrm{B})\!</math> can be represented as digraphs on the four points of their common syntactic domain <math>S = I =\!</math> <math>\{ {}^{\backprime\backprime} \mathrm{A} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{B} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{i} {}^{\prime\prime}, {}^{\backprime\backprime} \mathrm{u} {}^{\prime\prime} \}.\!</math> Since <math>\mathrm{Con}(L_\mathrm{A})\!</math> and <math>\mathrm{Con}(L_\mathrm{B})\!</math> are semiotic equivalence relations, their digraphs conform to the pattern that is manifested by all digraphs of equivalence relations. In general, a digraph of an equivalence relation falls into connected components that correspond to the parts of the associated partition, with a complete digraph on the points of each part, and no other arcs. In the present case, the arcs are given as follows:

In the context of 3-adic relations in general, Peirce provides the following illustration of the six ''converses'' of a 3-adic relation, that is, the six differently ordered ways of stating what is logically the same 3-adic relation:

−Logic will here be defined as ''formal semiotic''. A definition of a sign will be given which no more refers to human thought than does the definition of a line as the place which a particle occupies, part by part, during a lapse of time. Namely, a sign is something, ''A'', which brings something, ''B'', its ''interpretant'' sign determined or created by it, into the same sort of correspondence with something, ''C'', its ''object'', as that in which itself stands to ''C''. It is from this definition, together with a definition of ~~"~~formal~~"~~, that I deduce mathematically the principles of logic. I also make a historical review of all the definitions and conceptions of logic, and show, not merely that my definition is no novelty, but that my non-psychological conception of logic has ''virtually'' been quite generally held, though not generally recognized. (C.S. Peirce, ~~"~~Application to the ~~[[~~Carnegie Institution~~]]"~~, L75 (1902), NEM 4, 20~~-~~21).
