Speaker Theory
Suppose, however improbably,
that there are no other aspects which in the circumstances
could direct the audience's attention to the man
whom the speaker says is happy tonight. It would
remain enough that it is a plausible belief for
the speaker and audience to hold about him, and
which the speaker can exploit for referential
purposes, that he is drinking champagne.
It seems entirely natural
to say that what the PS does in these cases is
what all speakers are enthymematically doing anyway,
as an entirely natural extrapolation of the cases
shows: if the audience responds, 'he is not her
husband, he is her lover', 'it is not champagne,
it is Perrier water', the speaker replies, 'Oh
well I thought he or it was such-and-suchbut
anyway you know what I mean'.
This does not defend in
any way Russell's allegedly pure attributive theory,
in which the form of the example is represented
as 'the uniquest x to satisfy F, Gs', because
the epistemic restraint built into specification
of F imports something which is additional to
the purely conventional aspect of the other expressions
constituting F. We can best see what is at work
by reminding ourselves of Kripke's suggestion.
For Kripke, the distinction lies between semantic
and speaker reference. For some idiolect, the
semantic referent of an indexical-free designator
is fixed by general intentions of speakers to
pick out a given object by its means. Speakers'
referents are given by specific intentions on
specific occasions to refer to a given object.
And again familiarly, Kripke identifies simple
and complex cases; in the former, a speaker's
specific intention just is his general intention.
In the latter, his specific and general intentions
diverge, but as a matter of fact he believes that
his specific intention determines the same object
as his general intention. He might be right or
wrong but still succeed in referring. On this
view, D's 'attributive' case is nothing but the
simple case, his 'referential' case nothing but
the complex case.
On the PS view, however,
all cases are to be understood as complex cases.
Reflecting on the oddity of Kripke's distinction
suggests why they have to be so. It is surely
never the case, intentions to deceive apart, that
speakers believe that their specific and general
referential intentions diverge. Their choice of
designating expression is governed by a desire
to succeed in making reference. So as a matter
of fact speakers are always in Kripke's complex
case: they believe that their specific and general
intentions coincide. Indeed, the distinction between
the intentions is not one that speakers make from
inside their referring practice: it is one that
retrospectively offers in theoretical reflection
on the fact that many beliefs are defeasible.
But the PS builds recognition
of this fact of life into his practice. So his
is expressly the complex case: his specific intention
to refer is effected by articulably cautious attribution
of certain properties to the referent by means
of expressions whose conventional meaning is apt
for the task.
Among the points worth noting
here are the following. A familiar contrast between
conventional meaning and speaker meaning lies
in the offing of those remarks: it is just such
a Gricean distinction from which Kripke takes
his start, but this way with the outcome hints
that any account of conventional meaning is, pace
Grice, parasitic upon an account of speaker meaning:
that the former is, in a sense worth specifying,
the dry residue of agreements forced among speakers
seeking success for their intentions to mean.
This is a point which lies just off-stage in this
paper.
The second is that what
gave rise to the debate about a reference-attribute
distinction is ellipsis: the thought is that making
speakers express too little of what a model speakerthe
PSwould say is exactly what generates the
problem. And there is nothing philosophically
problematic about ellipsis.
But now we need to bring
in another feature of PS-hood, implied by the
conditions but not so far exploited. This feature
comes out in the final case I consider: a certain
employment of Putnam's Twin Earth argument.
Putnam challenged two received
assumptions, the first being that to know the
meaning of an expression is to be in a certain
sort of psychological state, and the second being
that the meaning of an expression determines its
extension. These assumptions entail that psychological
states determine the extension of terms. Putnam's
twin-earth case purports to show that this cannot
be so, giving us his celebrated conclusion that
meanings are not in the head. Of course this applies
just when the psychological states in question
are narrow, that is, understood concordantly with
'methodological solipsism', the view that psychological
states supervene on intrinsic states of an individual
considered independently of anything besides,
in particular without relation to environmental
factors causing or being effected by those states.
Now on PS theory the crux for meaning is point:
explanation of what an utterance means has to
make essential reference to what speakers intend
to convey. This means that a psychological state
privileged by the theory, viz. 'intending to mean
p', determines the extensions of expressions used.
Putnam's twin-earth considerations seem to block
this. Do they? I suggest not. The claim I think
we justify by appeal to PS theory is thisand
here we introduce the additional feature of PS-hood
required by the conditions: that 'intending
to mean p' does indeed determine extension, under
the two constraints (a) that the words used are
used according to what I shall label 'the Best
Dictionary', which reports the agreed, relatively
stable senses of expressions employed as tokens
of communicative exchange in the linguistic community,
and which does so according to the best current
theories of the linguistic community, and (b)
that the PS's audience of normally competent ordinary
speakers will so take it.
We get at this thought by
noting something about how the twin-earth case
is set up. The first thing to note is an apparently
tangential point, namely that rejection of methodological
solipsism does not by itself entail some kind
of realism about the domain of application of
the terms whose meanings are to be understood
broadly. For so far all that we have identified
as required in addition to a speaker's knowledge
of meaning is the existence of other speakers
whose interactions with him and one another constrain
that knowledge. If this is not enough to serve
as the broad context, then we need to find the
reason in Putnam's twin-earth argument. Does his
argument show that unless there is H2O and XYZ
out there on earth and twin-earth respectively,
Oscar and his twin could not respectively have
meant 'water' and 'water'? That of course is not
what Putnam sought to conclude: his argument was
not aimed at proving the existence of the external
world, but at showing that meanings cannot be
individuated narrowly. So there are three assumptions
at work in the twin earth case. The existence
of the different waterswater H2O and water
XYZis assumed, as is the qualitative identity
of the twins' narrow states, as in the twins'
woeful ignorance of views current about water
in their worlds. Thus richly equipped, the argument
has no difficulty in delivering its celebrated
conclusion. But before we accept these premisses
in our welcome of the conclusion, we should enquire
whether the twin-earth tale could not be as well
or better told, because more parsimoniously told,
using just the idea that the meanings of expressions
in a language are the agreed dry residue of speakers'
meanings.
Any individual's problem
is that he does not know everything that all other
speaker's jointly know about the meaning of the
expressions in his language. This is unsurprising:
if some best and latest dictionary pooled a community's
knowledge of meanings, it would be a rare individual
whose linguistic knowledge came close. Such a
dictionary would report the knowledge possessed
by the completest speakersOOSsincluding,
for example, chemists and hydroengineers. Now
let us bring in the PS, who knows everything in
the best dictionary. Note that the PS is not
