The seman)cs-‐pragma)cs interface
The necessity of a Seman)cs-‐Pragma)cs Interface (SPI) is due to the following empirical facts: A. some pragma)c inferences (Conversa)onal Implicatures
CIs) are triggered by linguis)c items; B. pragma)c meaning seems to be more than non-‐truth-‐
condi)onal, as explicatures; C. pragma)c meaning can be determined by truth-‐
condi3onal meaning (causal connec)ves, nega)on).

A. Linguis)c and pragma)c meanings: implicatures
Generalized conversa3onal implicatures (GCIs) raise the issue of the encoding of pragma3c meaning: (a) Are conversa)onal implicature
part of the seman)c meaning? (b) Are they contextually
triggered? The first op)on leads to the ‘pragma3c meaning by default’ solu)on: a CI is triggered by a default inference.
The second op)on leads to the contextual solu)on: a CI must be contextually licensed or contextually blocked. 1. Some elephants have trunks.

Predic)ons
The default approach predicts that CIs should not be costly, since they are default inference.
But it has been shown that they are (Noveck 2001). The contextual approach predicts that CIs are favored in some contexts and blocks in others.
Experimental approaches on scalar implicatures shows that the contextual approach makes be?er predic3ons than the default one (Noveck 2001, Reboul 2004, Noveck & Sperber 2007, Noveck & Reboul 2010).
6
FACULTÉ DES LETTRES Département de linguistique
ConsequencesThe avantage of the default approach is that CIs are aBached to lexical meaning.
Its disadvantage lies in its erroneous predic3ons. The disadvantage of the contextual approach is that pragma3c meaning is not calculable without accessing contextual assump)ons.
Its advantage is that it makes correct predic3ons. SPI is clearly defined in the default approach, whereas it is unclear in the contextual one:
What is represented in lexical meaning? One op)on is the Relevance-‐theore)cal difference between linguis3cally encoded and communicated inferred concepts (ad hoc concepts). But what is linguis3cally encoded?

FACULTÉ DES LETTRES Département de linguistique
B. Explicatures vs. CIsExplicatures are pragma3c meaning which are not conveyed implicitly.
An explicature is an assump)on which is a development of the logical form encoded by the u?erance (Sperber & Wilson 1986, Moeschler & Reboul 1994).
1. Mary is happy: she finally met a bachelor. CIs are tradi)onally defined as non-‐truth-‐condi3onal meanings.
They do not contribute to the truth-‐value of the uBerance: non-‐truth condi)onal meaning is cancelable.
2. John fell and Mary pushed him, but not in this order. Explicatures are pragma3c truth-‐condi3onal meanings: they determine the truth-‐value of the uBerance: 3. It’s always the same at par8es: either I get drunk and no-‐one will talk to me
or no-‐one will talk to me and I get drunk.
8
FACULTÉ DES LETTRES Département de linguistique
ConsequencesThe no)on of explicature reduces the area of CIs, and breaks the clear-‐cut border between seman)cs and pragma)cs.
There are pragma3c meanings which are developments of logical forms and are truth-‐condi3onal.
Explicatures should not be cancelable, as CIs are. In fact, explicatures are cancelable: 1. Abi and Fée climbed the Roche de Solutré [together] 2. Abi and Fée climbed the Roche de Solutré, but not together. 3. Abi and Fée did not climb the Roche de Solutré together, but
separately.
9
FACULTÉ DES LETTRES Département de linguistique
C. Pragma)c meaning determined by truth-‐condi)onal meaning
Conversely, there are pragma3c meanings which are dependent of truth-‐condi3onal meanings. This is the case with temporal and causal meaning of connec3ves like and and because:
P and Q: in order for P and Q to mean P and then/because of this Q, both conjuncts must be true. P because Q: in order for P because Q to infer that Q CAUSE P, both P and Q must be true.
10
FACULTÉ DES LETTRES Département de linguistique
Empirical evidencesAnd temporal meaning can be defeated: in this case, what is evaluated is not the truth vs. falsehood of proposi)ons, but the temporal rela)on between them (Wilson & Sperber 2012): 1. What happened was not than Peter leT and Mary got angry but that Mary got
angry and Peter leT. Because causal meaning cannot be defeated: what can be false is either the effect, or the causal rela3on: 2. John did not fall because Mary pushed him
a. John did not fall, and the reason is that Mary pushed him (before he could fall)
b. It is not because Mary pushed John that he fell, but because he slipped down. Hence, and and because ‘presuppose’ the truth of the proposi)on they connect (Blochowiak 2014).
11
FACULTÉ DES LETTRES Département de linguistique
Provisory conclusion
SPI is more complex than the tradi)onal Gricean pragma)cs predicts: the Gricean criteria defining the border between Seman)cs and Pragma)cs are ruled out:
the truth-‐condi)onal vs. non truth-‐condi)onal aspect of meaning the cancela)on criterion the implicit vs. explicit aspect of meaning.
12
FACULTÉ DES LETTRES Département de linguistique
Possible SPIsWhat are the possible S-‐P interfaces? There are two classical answers: a. the pragma3cs as output of the linguis3c system b. the pervasive pragma3c intrusion into seman3cs Both proposals are unsa3sfactory: a. the first solu)on implies a step by step processing (from
syntax to pragma)cs), and cannot account for pragma)c intrusion, neither for parallel processing;
b. the second solu)on cannot account for the rela3on between explicatures and implicatures, and leads to the Gricean circle.
14
FACULTÉ DES LETTRES Département de linguistique
a. The linear modelThe first solu)on is a kind of linear model:
seman)cs in the output of syntax pragma)cs is the output of seman)cs
Two big issues: seman3cs is an interface of grammar, not an output; pragma3cs does not belong to the linguis)c system: it is not an input system (Fodor 1983), but belong to the central system of the mind (Sperber & Wilson 1986).
NB: for RT (revised version), there is a pragma3c module, including a comprehension and an argumenta3ve module

Seman)cs as an interface
In a formalist framework (for instance the Minimalist Program), logical forms are the interface of the computa3onal system, as phonological forms are.
In Hauser, Chomsky & Fitch (2002), they are defined as the sensory-‐motor and the conceptual-‐inten3onal interfaces. The assump)on is that phonological formes (PF) and logical forms (LF) are interfaces of the grammar, and belong to the faculty of language in the broad sens (FLB), whereas FLN (faculty of language in the narrow sense) is restricted to recursion.
This picture contrasts with the defini)on of language as form-‐meaning pairs, where no hierarchy between formal or seman)c structures dominates and Jackendoff’s approach -‐ the flat phonological, syntac3c and conceptual structures (2002), implying 5 types of interfaces.
16
FACULTÉ DES LETTRES Département de linguistique
b. Linguis)cs and pragma)cs
One strong assump)on of pragma3c theory is that pragma3cs is not a component of linguis3cs:
Pragma)cs is part of the central system of the thought (Sperber & Wilson 1986) -‐ pragma)c is not a module and not devoted to specific tasks.
It means that pragma3cs deals with different inputs (supposed be translated is a same format) processed by the inferen)al central system. Linguis)c informa)on is one among other types of informa)on processed by the central system of the thought. What then is the rela)on between linguis3cs and pragma3cs?
17
FACULTÉ DES LETTRES Département de linguistique
Pragma)c intrusionOne main issue with SPI is pragma3c intrusion. The concept of pragma8c intrusion implies that pragma3c interpreta3on affects seman3c interpreta3on. Classical data arguing for pragma)c intrusion (Levinson 2000): condi3onal perfec3on (Geis & Zwicky 1971)

5. I don’t like Alice mirror maxim (Harnish 1976)
6. Harry and Sue bought a piano

What’s wrong with pragma)c intrusion?
Pragma3c intrusion, in a neo-‐Gricean perspec)ve, implies that pragma3c inferences contribute to truth-‐condi3ons.
For instance, in bridging, reference resolu)on (as a pragma)c process) determines the full proposi)on to be truth-‐condi)onally evaluated.
This yields the Gricean circle: Implicatures (what is implicated) are computed on the base of the proposi)on expressed (what is said). Implicatures determine the proposi)on expressed (truth-‐condi3onal meaning).

Implica)ons
Pragma3c intrusion shows that the border between seman)cs and pragma)cs is porous. Some aspects of pragma)c meaning are truth-‐condi)onal (explicatures), other are not (implicatures). Other rela)ons need to be taken into account, as entailment and presupposi3on, in order to fix SPI (Moeschler 2013).
21
FACULTÉ DES LETTRES Département de linguistique
Why do we need SPI?
SPI has as a main func)on to allow quick and efficient informa3on transfer from non-‐linguis)c sources to linguis)c ones, and vice-‐versa. Contextual informa3on is generally required for proposi)onal enrichment to trigger implicit and explicit inferred meaning. Linguis3cally encoded meaning is the star)ng point to enrichment process to access reference, inferred conceptual representa)ons, and implicatures.
23
FACULTÉ DES LETTRES Département de linguistique
One example: scalar implicatures
Scalar implicatures (SIs) are a classical case of SPI, allowing predic)ons about its func)on. SIs triggered by quan)fiers are closely connected with their logical meaning, as represented by the logical square (Horn 2004):
I +> not-‐A = O O +> not-‐E = I

What is the issue?
In what follows, I will assume the strong connec3on between par3culars, but propose another (par)al) analysis. I will insist on what is linguis3cally encoded (seman8cs) and what is inferred (pragma8cs). The results will be that the pragma3c meanings of some and some…not will be interpreted as explicatures.

What can be the seman3cs and the pragma3cs of some and some…not? Three assump)ons:
a. there is a strong connec3on between both par3culars: this rela)on is expressed by a complement opera)on;
b. their seman3cs is defined as what is truth-‐condi3onally incompa3ble with each par)cular: i. some is seman3cally (logically) incompa3ble with no: they are
contradictories ii. some…not is seman3cally (logically) incompa3ble with all: they are
contradictories c. their pragma3cs is given by their incompa3bility with their upper-‐bound

The role of explicature in uBerance comprehension
The interpreta3on of par3culars is directly dependent of their truth-‐condi3onal meanings. Their meanings are crucially context-‐dependent: the not-‐all and not-‐none interpreta)ons can or cannot be triggered, depending on what the context is. The rela)on with their seman3cs is based on an exclusion condi3on.
32
FACULTÉ DES LETTRES Département de linguistique
The exclusion condi)on
The processing of the seman)cs and pragma)cs for some and some…not is the following: 1. exclude the incompa3ble seman3c meaning 2. exclude the incompa3ble pragma3c meaning 3. enrich the pragma)c meaning by explicature. This procedure yields a specifica3on reading by narrowing the seman3cs of the par3culars.

b. Cogni3ve explana3on: the par33on reading for some and some not allows an efficient and rapid processing, avoiding useless cogni)ve processes.

SPI is mainly a linguis3c issue: seman3c meaning is the locus of pragma3c processes. How can conceptual (and procedural) meaning be located in seman)c meaning? How is this representa)on compa)ble with a contextual approach? The argument will be based on temporal and causal connec3ves meanings.

Three connec)ves with different seman)c and pragma)c meanings
How to explain the differences in seman)c and pragma)c meanings between parce que, donc, et (because, therefore, and)? 1. Jean est tombé parce que Marie l’a poussé.
‘John fell because Mary pushed him.’ 2. Marie a poussé Jean, donc il est tombé.
‘Mary pushed John, therefore he fell.’ 3. Marie a poussé Jean, et il est tombé.
‘Mary pushed John, and he fell. The hypothesis is that the difference is not in the meanings encoded by connec3ves, but in the layer of meaning they encode. All connec)ves encode at some level a CAUSE rela)on and allow inferring the fac3ve vs. non-‐fac)ve status of the proposi)ons.
38
FACULTÉ DES LETTRES Département de linguistique
Connec)ves and their inferen)al meaning
In all cases, temporal and causal inferences are obtained, but with different seman3c and pragma3c paths. Some contents are the result of entailments, others are the result of explicatures or implicatures.
When a proposi)on is entailed, it must be true. When a proposi)on is developed as an explicature, it allows assigning a truth-‐value to the uBerance. When a proposi)on is an implicature, it can be cancelled.
1. Jean est tombé parce que Marie l’a poussé a. John fell & Mary pushed him b. Mary pushed John CAUSE John fell
2. Marie a poussé Jean, donc il est tombé. a. John fell b. POSSIBLE (Mary pushed John
CAUSE John fell) 3. Marie a poussé Jean, et il est tombé.
a. John fell & Mary pushed him b. POSSIBLE (Mary pushed John
CAUSE John fell)

Some examplesDonc and et are compa)ble with situa)ons where the CAUSE rela)on is explicitly given as possible but not certain.
1. Marie a poussé Jean, donc il est peut-‐être tombé.‘Mary pushed John, therefore he may have fallen.’
2. Marie a poussé Jean, et il est peut-‐être tombé.‘Mary pushed John, and he may have fallen.’
3. ?? Jean tombé parce que Marie l’a peut-‐être poussé.‘John fell because Mary may have pushed him.’
With parce que, the causal rela)on can be denied: 3. Jean n’est pas tombé parce que Marie l’a poussé, mais parce qu’il a
manqué une marche.‘John did not failed because Mary pushed him, but because he missed a step’.

Entailment Implicature Explicature
parce que P Q Q CAUSE P
donc P ♢(P CAUSE Q)
et P Q ♢(P CAUSE Q)
These connec)ves trigger different speaker’s commitment about the truth of the proposi3ons expressed: a. P is entailed by all connec3ves – parce que, donc, et. b. Q is entailed by parce que and et. c. The CAUSE rela3on is an explicature with parce que, and an implicature with iconic
order under the scope of a modal operator (et, donc) – it can be cancelled. Hence, the same informa3ve content is seman3cally and pragma3cally distributed in different ways.

Accessibility and strength What is the impact of the type of inference on u?erance interpreta3on? Two criteria can be used in order to rank inferences: their seman3c vs. pragma3c nature, and the type of inferred content: implicit vs. explicit. Accessibility and strength are two criteria allowing to differen)ate between entailment, explicature and implicature:
accessibility explicature > implicature > entailment strength entailment > explicature > implicature

Accessibility and strength Seman3c rela3ons (entailment) are less accessible, but stronger. Pragma3c rela3ons (explicature and implicature) are more accessible, but lighter (they can be more easily denied) Explicatures are stronger than implicatures because implicatures rule out a logical constraint seman)c rela)ons cannot have (see the entailment rela)on):

ConsequencesLinguis3c lexical items are the (main) locus of SPI. SPI can be made visible by the con3nuum of seman3c and pragma3c rela3ons as entailment, (presupposi)on,) explicatures and implicatures.
Causal connec3ves show how atomic and complex proposi)onal meanings are distributed in the seman)cs-‐pragma)cs con)nuum. Quan3fiers as some and some…not show how basic seman)c rela)ons (inclusion, intersec)on) are distributed at the seman)c and pragma)c level.
