Syntax and semantics are indeterminate, and modern 'semantics' is a bogus subject [Quine, by Lycan]
     Full Idea: Quine has argued tirelessly that syntax and 'semantics' are indeterminate, and linguistic semantics of the sort that is currently in favor is a pseudoscience and a pipe dream.
     From: report of Willard Quine (Methodological Reflections on Current Linguistic Theory [1972]) by William Lycan - The Trouble with Possible Worlds 02
     A reaction: I think the defence of such things is that they may not integrate into science very well (or even integrate at all), but semantics is intended to integrate into philosophy, and is motivated by philosophical concerns. Quine may be right!
We still lack an agreed semantics for quantifiers in natural language [Stalnaker]
     Full Idea: We still do not know how to give a direct semantics for the quantifiers of a natural language; that is something that we still do not know how to do (or at least how it is done remains controversial).
     From: Robert C. Stalnaker (Mere Possibilities [2012], 4)
     A reaction: I am struck by how rapidly the domain of quantification changes, even in mid-sentence, in the course of an ordinary conversation. This is decided almost entirely by context, not by pure ('direct'?) semantics.
'Descriptive' semantics gives a system for a language; 'foundational' semantics give underlying facts [Stalnaker]
     Full Idea: 'Descriptive' semantics gives a semantics for the language without saying how practice explains why the semantics is right; …'foundational' semantics concerns the facts that give expressions their semantic values.
     From: Robert C. Stalnaker (Reference and Necessity [1997], §1)
     A reaction: [compressed] Sounds parallel to the syntax/semantics distinction, or proof-theoretical and semantic validity. Or the sense/reference distinction! Or object language/metalanguage. Shall I go on?
English has no semantic theory, just associations between sentences and thoughts [Fodor]
     Full Idea: English has no semantics. Learning English isn't learning a theory about what its sentences mean, it's learning how to associate its sentences with the corresponding thoughts.
     From: Jerry A. Fodor (Concepts:where cogn.science went wrong [1998], Ch.1)
     A reaction: This sounds remarkably close to John Locke's account of language (which I always thought was seriously underrated). Presumably we can then say that the 'thought' (or Locke's 'idea') is the meaning, which is old-fashioned real meanings.
Broad semantics holds that the basic semantic properties are truth and denotation [Fodor]
     Full Idea: Broad semantic theories generally hold that the basic semantic properties of thoughts are truth and denotation.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b)
     A reaction: I think truth and denotation are the basic semantic properties, but I am dubious about whole-hearted broad semantic theories, so I seem to have gone horribly wrong somewhere.
Semantics (esp. referential semantics) allows inferences from utterances to the world [Fodor]
     Full Idea: All you need for inferring from John's utterance to the world is the sort of thing that a semantics (i.e. referential semantics) provides.
     From: Jerry A. Fodor (LOT 2 [2008], Ch.3.5)
     A reaction: Fodor is very good at saying nice simple things like that. But it is not enough to infer what objects are being discussed. All the hard cases must be covered (denials of existence, reference to non-existence, intentional contexts, modal claims).
Semantics relates to the world, so it is never just psychological [Fodor]
     Full Idea: Semantics is about constitutive relations between representations and the world. There is, as a matter of principle, no such thing as a psychological theory of meaning.
     From: Jerry A. Fodor (LOT 2 [2008], Ch.3.5)
     A reaction: The second sentence is in capital letters, but I am still not convinced. The classic difficulty seems to be that you have to use language to pick out the things in the world that are being referred to. Of course, at some point you just see the objects.
Teleosemantics equates meaning with the item the concept is intended to track [Papineau]
     Full Idea: The teleosemantic view of perceptual concepts is that the referential value of the concept can be equated with those items which it is the biological function of the concept to track.
     From: David Papineau (Thinking about Consciousness [2002], 4.6)
     A reaction: This seems to work quite nicely for 'bird', which is concept which is used to track birds. It might even work for complex entities, or abstract entities, or even negative entities. Imagination must play a role in that last one.
Semantics as theory of meaning and semantics as truth-based logical consequence are very different [Soames]
     Full Idea: There are two senses of 'semantic' - as theory of meaning or as truth-based theory of logical consequence, and they are very different.
     From: Scott Soames (Why Propositions Aren't Truth-Supporting Circumstance [2008], p.78)
     A reaction: This subtle point is significant in considering the role of logic in philosophy. The logicians' semantics (based on logical consequence) is in danger of ousting the broader and more elusive notion of meaning in natural language.
Semantics is either an assignment of semantic values, or a theory of truth [Fine,K]
     Full Idea: On one view, a semantics for a given language is taken to be an assignment of semantic values to its expressions; according to the other, a semantics is taken to be a theory of truth for that language.
     From: Kit Fine (Semantic Necessity [2010], Intro)
     A reaction: The first is Frege, the second Tarski via Davidson, says Fine. Fine argues against these as the correct alternatives, and says the distinction prevents us understanding what is really going on. He votes for semantics as giving 'semantic requirements'.
Semantics is a body of semantic requirements, not semantic truths or assigned values [Fine,K]
     Full Idea: Semantics should be conceived as a body of semantic requirements or facts - and not as a body of semantic truths, or as an assignment of semantic values.
     From: Kit Fine (Semantic Necessity [2010], 5)
     A reaction: The 'truths' view is Tarski, and the 'values' view is Frege. You'll have to read the Fine paper to grasp his subtle claim.
That two utterances say the same thing may not be intrinsic to them, but involve their relationships [Fine,K]
     Full Idea: In my 'Semantic Relationism' the fact that two utterances say the same thing is not entirely a matter of their intrinsic semantic features; it may also turn on semantic relationships among the utterances of their parts not reducible to those features.
     From: Kit Fine (Semantic Relationism [2007], Intro)
     A reaction: You'll need to read the book slowly several times to get the hang of this, but at least it allows that two different utterances might say the same thing (express the same proposition, I would say).
The two main theories are Holism (which is inferential), and Representational (which is atomistic) [Fine,K]
     Full Idea: For holists a proper theory will be broadly inferential, while for their opponents it will be representational in character, describing relations between expressions and reality. Representational semantics is atomist, holist semantics inferential.
     From: Kit Fine (Semantic Relationism [2007], Intro)
     A reaction: Fine presents these as the two main schools in semantics. His own theory then proposes a more holistic version of the Representational view. He seeks the advantages of Frege's position, but without 'sense'.
The standard aim of semantics is to assign a semantic value to each expression [Fine,K]
     Full Idea: The aim of semantics, as standardly conceived, is to assign a semantic value to each (meaningful) expression of the language under consideration.
     From: Kit Fine (Semantic Relationism [2007], 1.G)
     A reaction: Fine is raising the difficulty that these values can get entangled with one another. He proposes 'semantic connections' as a better aim.
We should pursue semantic facts as stated by truths in theories (and not put the theories first!) [Fine,K]
     Full Idea: A 'semantics' is a body of semantic facts, and a 'semantic theory' is a body of semantic truths. The natural order is a theory being understood as truths, which state facts. Davidson, alas, reversed this order, with facts understood through theories.
     From: Kit Fine (Semantic Relationism [2007], 2.C)
     A reaction: [compressed; he cites Davidson 1967, and calls it 'one of the most unfortunate tendencies in modern philosophy of language, ..as if chemistry were understood in terms of formulae rather than chemical facts'].
Referentialist semantics has objects for names, properties for predicates, and propositions for connectives [Fine,K]
     Full Idea: The standard referentialist semantics for a language with names is that the semantic value of the name is the object, the content of a predicate is a property, and the content of a logical connective is an operation on propositions.
     From: Kit Fine (Semantic Relationism [2007], 2.F)
     A reaction: My particular bęte noire is the idea that every predicate names a property. It is the tyranny of having to have a comprehensive semantic theory that drives this implausible picture. And I don't see how an object can be a semantic value…
Fregeans approach the world through sense, Referentialists through reference [Fine,K]
     Full Idea: Fregeans emphasise an orientation towards the speaker: possession of sense makes language meaningful, and language relates to the world through sense. For the Referentialist its representational relationships make it meaningful, and relate it to the world
     From: Kit Fine (Semantic Relationism [2007], 2.G)
     A reaction: The Referentialist approach is for Kripkean fans of direct reference, rather than the Fregean reference through descriptions. I am inclined to favour the old-fashioned, deeply discredited, much mocked Fregean approach.
How does inferentialism distinguish the patterns of inference that are essential to meaning? [Williamson]
     Full Idea: Inferentialism faces the grave problem of separating patterns of inference that are to count as essential to the meaning of an expression from those that will count as accidental (a form of the analytic/synthetic distinction).
     From: Timothy Williamson (Knowledge First (and reply) [2014], p.6)
     A reaction: This sounds like a rather persuasive objection to inferentialism, though I don't personally take that as a huge objection to all internalist semantics.
Internalist inferentialism has trouble explaining how meaning and reference relate [Williamson]
     Full Idea: The internalist version of inferentialist semantics has particular difficulty in establishing an adequate relation between meaning and reference.
     From: Timothy Williamson (Knowledge First (and reply) [2014], p.6)
     A reaction: I would have thought that this was a big problem for referentialist semantics too, though evidently Williamson doesn't think so. If he is saying that the meaning is in the external world, dream on.
Inferentialist semantics relies on internal inference relations, not on external references [Williamson]
     Full Idea: On internalist inferential (or conceptual role) semantics, the inferential relations of an expression do not depend on what, if anything, it refers to, ...rather, the meaning is something like its place in a web of inferential relations.
     From: Timothy Williamson (Knowledge First (and reply) [2014], p.6)
     A reaction: Williamson says the competition is between externalist truth-conditional referential semantics (which he favours), and this internalist inferential semantics. He is, like, an expert, of course, but I doubt whether that is the only internalist option.
The 't' and 'f' of formal semantics has no philosophical interest, and may not refer to true and false [Williamson]
     Full Idea: In a formal semantics we can label two properties 't' and 'f' and suppose that some sentences have neither (or both). Such a manoeuvre shows nothing of philosophical interest. No connection has been made between 't' and 'f' and truth and falsity.
     From: Timothy Williamson (Vagueness [1994], 7.2)
     A reaction: This is right, and means there is a huge gulf between 'formal' semantics (which could be implemented on a computer), and seriously interesting semantics about how language refers to and describes the world.
In 'situation semantics' our main concepts are abstracted from situations [Mares]
     Full Idea: In 'situation semantics' individuals, properties, facts, and events are treated as abstractions from situations.
     From: Edwin D. Mares (Negation [2014], 6.1)
     A reaction: [Barwise and Perry 1983 are cited] Since I take the process of abstraction to be basic to thought, I am delighted to learn that someone has developed a formal theory based on it. I am immediately sympathetic to situation semantics.
Entailment is modelled in formal semantics as set inclusion (where 'mammals' contains 'cats') [Dougherty/Rysiew]
     Full Idea: Entailment is modelled in formal semantics as set inclusion. 'Cat' entails 'mammal' because the cats are a subset of the mammals.
     From: Dougherty,T/Rysiew,P (What is Knowledge-First Epistemology? [2014], p.10)
     A reaction: I would have thought that this was only one type of entailment. 'Travelling to Iceland entails flying'. Travelling includes flying, the reverse of cats/mammals, to a very complex set-theoretic account is needed. Interesting.
The semantics of a sentence is its potential for changing a context [Magidor]
     Full Idea: The basic semantics of sentences are not truth-conditions, but rather context change potential, which is a rule which determines what the effect of uttering the sentence would be on the context.
     From: Ofra Magidor (Category Mistakes [2013], 5.3.2)
     A reaction: [I. Heim's 'renowned' 1983 revision of Stalnaker] This means the semantics of a sentence can vary hugely, depending on context. It is known as 'dynamic semantics'. 'I think you should go ahead and do it'.
Semantic theory assigns meanings to expressions, and metasemantics explains how this works [Schroeter]
     Full Idea: A semantic theory assigns semantic values (meanings) to particular expressions of the language. In contrast, a metasemantic theory explains why expressions have those semantic values, appealing to facts about speakers and communities.
     From: Laura Schroeter (Two-Dimensional Semantics [2010], 3.4)
     A reaction: Presumably some people only want the metasemantic version. I assume that the two are entangled, but I would vote for both.
Success semantics explains representation in terms of success in action [Jenkins]
     Full Idea: Success semantics is the attempt to understand mental representation by thinking about the ways in which representing the world can lead to success in action.
     From: Carrie Jenkins (Grounding Concepts [2008], 6.3)
     A reaction: I take this to be what is also known as 'teleological semantics'. It sounds to me as if this might help to explain success in action, but isn't going to explain the representations that result in the success.
