Keith Donnellan on Causal Reference






Keith Donnellan believed that the statement


“Santa Claus will come tonight.”

isn't even a bona fide proposition; let alone a true or false one. In his paper, ‘Speaking of Nothing’, he says that
“can one even speak and be understood when using a singular expression with no referent?” (pp, 6-7)
However, Donnellan would accept a paraphrase:

“According to the legend, Santa Claus will come tonight."

And that would be true.

However, Donnellan spots a problem. According to the legend “Santa will come tonight”; though the legend doesn’t also say that “Santa Claus doesn't actually exist”. At an intuitive level, I don’t see what Donnellan’s problem is. The legend, sure, doesn’t have any position, really, on Santa’s existence. But so what? Why does that make the kid’s statement not understandable? Why does it make it, automatically, not even a proposition? Again, why impose ontological rectitude onto meaning and the very acceptance of proposition qua proposition? I don’t see the connection. Perhaps I’m being naïve; but isn’t it only the kid’s belief that a nonexistent to be an existent that’s at fault? This doesn't render his statement non-propositional or meaningless.

Perhaps I should focus on Donnellan’s belief that “Santa will not come tonight” isn't a proposition. Why? According to D a proper name (e.g., “Santa”) must have one of two things (or both). It must be causally connected to its referent or it must have “descriptive content”. It seems that D thinks that “Santa” has neither That is, if the subject-term, “Santa”, has no “descriptive content” or “historical connection” to its referent (which it can’t, because Santa never existed), then the proposition “Santa will not come tonight” isn't a proposition. And it isn't a proposition because of the problematic proper name. Though I still think it's simply a stipulation or even a dictat to argue that “Santa will not come tonight” isn't a proposition.

The thing which seems to be motivating D’s position is an attempt to save realism. That is, if we can have a causal theory of reference which evidently excludes “Santa”, then we can distinguish real propositions like “Tony Blair will come tonight” from “Zeus is angry with us”.

There is another realist move in this game.

Proper names shouldn't rely on being tied to “descriptive content”. This would give individual minds too much power and direct causal reference less power. Associating descriptive content with proper names is, well, idealistic. A causal connection to Tony Blair, or the “Tony Blair” relation to Tony Blair, is concrete. “The big liar at Number Ten” is, of course, idealist; or at least dependent on an individual mind (or minds). And the definite description that I have tied to “Santa” may be very different to the one you have tied to “Santa”. What would secure, therefore, necessary identity of reference?

Donnellan’s causal theory of reference, which excludes “Santa”, is the realist’s way of avoiding not just idealism, but relativism. Conventions, conceptual schemes, identifying descriptions, etc. are all “subjective”. However, causal processes impose themselves on us. We are therefore firmly tied to the world.

Although I think that my explication of D’s position is broadly correct, I still don’t see how “Santa will not come tonight” is rendered non-propositional and “Santa” non-understandable. This isn't because I have a point with D’s ontological/philosophical view of reference (actually, I do); but that his conclusions about the said statement don’t follow from his analysis of reference.

To finish, I would like to agree with D on his rejection of Russell’s views on these matters. That is

“God does not exist.”
is not an abbreviation for

“There is no entity such that…”

Though that’s to get into Bertrand Russell’s position.

Why does “failure of a complex reference simply make a proposition false” (687)? What is “failure of reference”? Can’t we refer to something non-spatiotemporal? And is, say, Sherlock Holmes really non-spatiotemporal? Perhaps we could say that Holmes exists in minds, on the page, in letters, on the screen, in pictures. All these are spatiotemporal things. Though are they simply representations of Holmes? That would be the case if he were something other than his representations; though is he something other? Holmes in the works of Conan Doyle is Holmes isn't a representation of Holmes. We could have representations of what Conan Doyle wrote; though not of Homes as a spatiotemporal object.

So reference needn't be to something that's spatiotemporal in the strict sense of Holmes being made of flesh and blood. We refer to numbers after all. We talk about the number 2. The number 2 isn't concrete. It isn't spatiotemporal (on many readings). Are negative facts like “John is not here” a reference to something spatiotemporal? In one sense, yes. The referent is the space not filled by John. What about non-spatiotemporal historical facts? Can we simply say that, well, at on point they were spatiotemporal; so historical facts are parasitical on these past spatiotemporal events?

Names, Reference & Logical Translations

Perhaps my position on the analyses or translations of everyday sentences is similar to late Wittgenstein's. That is,

“it occurred to him that the logical structure of language might be visible on its surface and might actually be gathered from the ordinary uses that we make of words in ordinary situations”. (690)

The only problem with that is that Wittgenstein thought the “logical structure” was still being seen, rather than the grammatical structure. I’m not sure if this amounts to much of a difference. If the logical structure of everyday statements were “visible”, then wouldn’t it actually be the grammatical structure we were talking about? This prompts the question: What precisely is the difference between grammatical form and logical form?

Here’s another attempt to secure realism from all-comers:

“…Keith Donnellan in protest against the view common to Russell and Searle that reference is determined by the speaker’s intentions…” (111)

Surely speakers’ intentions must be part of the story. This seems like a complete separation of reference from mind. Or, reference/causation is necessary and sufficient, minds just eat the crumbs.

Speakers must intend to refer to something, whether or not there is a direct causal pathway from referent to mind.

Take Strawson's peculiar position. According to him,

“God is in heaven.”

is neither true or false, because

“There exists something which is God.”

is false. It must be neither true nor false because there's no God to be in heaven or anywhere else. That’s why it isn’t true or false. However, the existential “There exists something which is God” is making a claim about existence, not about the whereabouts of an existent. There it is plainly false. How can it be true that “God is in heaven” when there's no God? And how can it be false that “God is in Heaven” for exactly the same reasons? The subject, God, doesn't exist, so the predicate, “is in Heaven”, can be neither true nor false.

Though I still intuitively think that we can call “God is in heaven” false, without indulging in metaphysical existence claims. It's false that there is God (and heaven), and it's therefore false that God is in heaven. So the whole statement is false. Or rather you can say it is false because of your position on God’s existence; though you shouldn't thereby deny its position as a proposition.

If we deny its propositional status, then perhaps we can - by definition - call it “meaningless”. But we can’t allow this for the simple reason that it isn’t meaningless. It is philosophically problematic; though not meaningless.

We should make a distinction between nonexistents that were never taken to be existents (Homes, Superman) and nonexistents that have been taken as existents (God, Zeus, phlogiston).

Talk about Holmes and Superman doesn't contain or imply existence claims. Talk about God does and talk about Zeus did. Therefore “Holmes lived on Baker Street” is true; whereas “God is in heaven” may be false.

When the person says that God is in heaven he's also saying that God exists. When the other person says that “Holmes lived on Baker Street” there's no existence claim contained in the statement. However, they both have equal status as propositions and are both equally meaningful. The difference being that one may be false and the other is true.

Descriptions


There must be other reasons why words are “used” other than use/convention; even if use/convention is indeed important. Why these conventions and not others? Has the answer got something to do with things beyond conventions (use)? Or is it simply a comparison of conventions to other conventions? Yes, language and behaviour are governed by conventions; though does the realist, for one, deny this? (Nagel would say that certain levels of knowledge, if that’s the correct word, are beyond linguistic matters.)

According to Searle, “a definite description [can be] used referringly” without being “construed as the assertion of an existential proposition” (Speech Acts, 1969). Reference is, therefore, not a commitment to the referent’s existence (at least not its spatiotemporal existence).

Why do Putnam, Kripke, and Donnellan attack “the principle of identifying descriptions” as “idealistic”? Can you really know or identify an object without a description? So what do these philosophers mean?

According to Searle, “Holmes” refers but “Mrs Holmes” doesn't simply because Holmes is a fictional character and Mrs Holmes is not.

Though what if I say that Mrs Holmes becomes a fictional object as soon as I talk about her? We could reply by saying that she has no defining characteristics, therefore she can’t be fictional. She has one: being the wife of Holmes. Isn’t one characteristic enough? How many characteristics does a fictional object need to be an “incomplete object” - never mind a “complete object”? Someone could of course say that she can’t be the wife of Holmes because Holmes didn’t have a wife; though that married status has itself has just been fictionalised. It doesn’t matter if Holmes, according to Doyle, had no wife. Holmes according to Murphy does.

Though can it still be the same Holmes if he's now stipulated to be married? Surely you can do anything with fictional characters. And, indeed, this often happens. (Think of the fact that Star Trek has continued long after the original writer/s stopped writing the scripts.) If David Lewis can put concrete spatiotemporal objects in possible worlds, why can’t I do the same with fictional objects? In this possible world the fictional object Holmes has a wife. No problem. So perhaps we are left with the prima facie strange idea that the fictional object Holmes lives in our world; whereas as the married fictional object Holmes lives in another possible world.
