FoCL, Chapter 21: Absolute and contingent propositions 373

21. Absolute and contingent propositions

21.1 Absolute and contingent truth

21.1.1 Notion of proposition in logic Specialized use, representing sentences which do not require knowledge of the utterance situation for semantic interpretation. This use is problematic because it constitutes a hybrid between an utterance and an expression. 21.1.2 Absolute propositions Express scientific or mathematical contents. These are special in that they make the interpretation largely independent from the usual role of the speaker. For example, in

In a right-angled triangle, it holds for the hypotenuse A and the cathetes B and C that A^{2} = B^{2} + C^{2}.

the circumstances of the utterance have no influence on interpretation and truth value. 21.1.3 Logical truth for absolute propositions Logical truth is represented by the metalanguage words false and true referring to the set-theoretic objects ∅ und {∅}, respectively. These serve as model-theoretic fix points into which the denotations of propositions are mapped by the metalanguage rules of interpretation.

21.1.4 Contingent propositions

Express everyday contents such as Your dog is doing well. Can only be interpreted – and thereby evaluated with respect to their truth value – if relevant circumstances of utterance situation (STAR point) are known.

21.1.5 Natural truth for contingent proposition

Represented by the truth values true^{c} and false^{c}. A contingent proposition such as

The Persians have lost the battle

is true^{c}, if the speaker is an eye witness who is able to correctly judge and communicate the facts, or if there exists a properly functioning chain of communication between the speaker and a reliable eye witness.

21.1.6 Procedural definition of the natural truth values true^{c} and false^{c}

A proposition – or rather a statement – uttered by, e.g., a robot is evaluated as true^{c}, if all procedures contributing to communication work correctly. Otherwise it is evaluated as false^{c}.

21.2.3 How the [+constructive,+sense] reanalysis disarms the Epimenides paradox

• the words true^{c} and false^{c} may be part of the object language without causing a logical contradiction in its semantics, and

• the recursion caused by the Epimenides paradox can be recognized in the pragmatics and taken care of without adversely affecting the communicative functioning of the system.

FoCL, Chapter 21: Absolute and contingent propositions 378

21.2.4 Basis of the reanalysis of the Epimenides paradox The distinction between (i) the logical truth values 1 and 0 from the T-condition and (ii) the natural truth values true^{c} and false^{c} from the object language replaces Tarski’s logical contradiction

a. C is 1 if and only if C is not 1

by the contingent statement

b. C is 1 if and only if C is not true^{c}.

21.2.5 Why the reanalysis is not open to logical semantics The procedural notion of natural truth – essential for avoiding Tarski’s contradiction – can be neither motivated nor implemented outside a [+constructive,+sense] ontology.

FoCL, Chapter 21: Absolute and contingent propositions 379

21.3 Frege’s principle as homomorphism

21.3.1 The communicative function of natural syntax is the composition of semantic representations by means of composing the associated surfaces. Montague formalized this structural correlation between syntax and semantics mathematically as a homomorphism. 21.3.2 Intuitive notion of a homomorphism A structural object so is homomorphic to another structural object SO, if for each basic element of so there is a (not necessarily basic) counterpart in SO, and for each relation between elements in so there is a corresponding relation between corresponding elements in SO. 21.3.3 Homomorphism as a relation between two (uninterpreted) languages Language-2 is homomorphic to language-1 if there is a function T which

• assigns to each word of category a in language-1 a corresponding expression of category A in language-2, and

• assigns to each n-place composition f in language-1 a corresponding n-place composition F in language-2, such that

• T(f(a,b)) = F((T(a))(T(b)))

21.3.6 Why the homomorphism condition by itself is not sufficient as a formalization of Frege’s principle

Frege’s principle is defined for analyzed surfaces, whereas natural language communication is based on unanalyzed surfaces. The problem is that the transition from unanalyzed to analyzed surfaces (interpretation) and vice versa (production) has been misused to enrich the levels of the analyzed surface and/or the meaning_{1} by means of zero elements or identity mappings.

21.3.9 Surface compositionality II (SC-II principle)

A semantically interpreted grammar is surface compositional if and only if

• the syntax is restricted to the composition of concrete word forms (i.e. no zero elements and no identity mappings),

• the semantics is homomorphic to the syntax, and

• objects and operations on the level of semantics which correspond to the syntax in accordance with the homomorphism condition may not be realized by zero elements or identity mappings.

21.4 Time-linear syntax with homomorphic semantics

21.4.1 Time-linear build-up of semantic hierarchies

• Step 1: Translation of word forms into component hierarchies Each word form is mapped into a semantic component hierarchy (tree). The structure of the tree is determined by the syntactic category of the word form.

• Step 2: Left-associative combination of component hierarchies For each combination of the left-associative syntax there is defined a corresponding combination of component hierarchies on the level of the semantics.

21.5.3 CoNSem hypothesis (Complexity of Natural language Semantics)

The interpretation of a natural language syntax within the C-LAGs is empirically adequate only if there is a finite constant k such that

• it holds for each elementary word form in the syntax that the associated semantic representation consists of at most k elements, and

• it holds for each elementary composition in the syntax that the associated semantic composition increases the number of elements introduced by the two semantic input expressions by maximally k elements in the output.

This means that the semantic interpretation of syntactically analyzed input of length n consists of maximally (2n − 1)· k elements.
