It's only a paradox if you had previously tried to convince yourself
that the meaning of a name was its bearer.
People perhaps used to do this rather effortlessly before the turn of
the 19th into the 20th centuries.
All sorts of people are confused about identity. It was almost gospel,
to take a notorious example, until the 1970s that the mind could not be
the brain. First year philosophy students were regularly taught to
dispatch the idea that these two things could be one and the same. It
was considered a logical or conceptual mistake. The perpetrators of this
disservice to anti-dualist thinking are never quite silenced but they
took a big hit when the distinction I have been describing became better
known to them. The scale of the trouble caused by a failure to
appreciate this distinction is big indeed.
OK, but what kinds of names/descriptions/processes have or need
references? And why?
Not sure what you are asking. I have given examples of phrases that have
references. And I have generally extended the idea for this thread into
all elements of sentences that point to features in the non-linguistic
world.
What use would it be for the detective to say
1. The man going into the flat where the blonde lives is your husband
if the various bits did not have references. You are welcome to use
"referents". The words are not important. What is important is that
things in the real world are being pointed to. It is a basic feature of
our using language. To pick out things in the world to say things about
them. To pick things out and say what the real relations between them
(non-linguistic relations) are.
When we start talking about causal relations, there must be something
about the world that makes one thing cause another. If it is not some
gluey spooky thing then it is something more complicated about how the
world really is. Scientists can tell us a great deal about these things.
But when the scientists are done, there are a few questions still. Hume
had some. Many of us have some. It is shear human curiosity to ask
questions. All I can tell you is that a great deal of confusion can
result from not distinguishing meaning from reference. I am not saying
that you cannot look into this distinction more closely.
"There are no blond women in the flat". Which women are you talking
about here exactly? What does "blond women" refer to?
(Let me guess, the blond women in the flat in all the other possible
worlds in which there _are_ blond women in the flat!)
No, no... <g>. No particular women are being identified here.
2. There are no blond women in the flat
is saying that there is a particular flat (note the 'the') about which
it is not true that it has a certain characteristic. It could as well be
"has no working toilet".
Or we could just say: it's obvious the sentence does refer to the flat,
but not to any women. So asking which women these are who aren't in the
flat is simply a question that doesn't make sense.
....
Yes you do need to know what is being referred to. But if I say "A
causes B" and you know what A and B refer to, is there anything else for
which you need to know what it refers to?
If you are curious like Hume and many of us, yes! We want to know what,
outside our sentences and our minds, is the causal bit about.
"I pull the lever and that causes the brake to come on". "Which
lever?"-- that one. "What brake?"-- that drum brake over there, at the
back of the car. These questions make sense and are concerned with
resolving references.
"OK so I know you mean this lever and that brake. But what's this causal
nexus you are talking about here?".
It's difficult to make much sense of this question, but I suppose I
could try answering, "the cable". "No, I don't mean the cable, I don't
mean the little As and Bs between the lever and the drum, that's a
matter for scientists. I mean what are you referring to, besides the
lever and the brake and the cable, when you say pulling the lever causes
the brake to come on? And don't just tell me what 'causes' means! Of
course I know that!"
I cannot make any sense of this question at all. How is it any less
nonsense than asking who are these women who aren't in the flat?
I did try to formulate the query that remains when the scientists have
finished their jobs when I asked about "What is common to A causes B for
all the many different values that fill these variables?" and went on to
summarise a few answers, including Hume's
Is it patent nonsense yet? (Wittgenstein: "my aim is: to teach you to
pass from a piece of disguised nonsense to something that is patent
nonsense").
Yes, the cause must exist out there in the real world for the statement
to be true.
But isn't that a question of correspondence rather than of reference?
I'm thinking of correspondence as a property of a whole statement, and
reference as a property of a term in a sentence.
We can step back at any time here and get less complex. What is a causal
relation in the world? What more is it than something going with
something else? Hume found nothing. I think a complicated story needs to
be told that makes Hume anything but actually right. Lewis tells a
story. Someone can choose not to tell stories but then how is this
different from either a lack of curiosity or a view of the primitiveness
of the causal relation (a bit like, what is it for something to *exist*
- on this I happen not to be further curious because I know nothing
clearer than this with which to investigate it.)
[...]
I would like to see how someone can understand causal statements without
readily understanding some simple counterfactuals.
I didn't say they couldn't. I was just trying to make sense of the idea
that counterfactuals are part of the very meaning of causation.
No, you are saying that bachelors are unmarried. Not trying to be funny
here, you are not defining anything.
Under what other circumstances would anyone ever use that sentence?
3. All bachelors are unmarried
Although, no matter what the circumstances, it is not asserting a
definition, I am not disputing that one might use it as an example in an
English language class. It is used often by philosophers as an example
of something true in order to discuss what makes it true and how it is
to be distinguished from many other types of sentences. Philosophers are
particularly nosey about necessity, both in maths and elsewhere.
You seem to think 3. is something a bit useless. No doubt you are right
in this particular case. But what if there are interesting necessary
statements? Maths. Other things. It is an open question how analytic
these are. It is indeed an open question what quite is the distinction
between analytic and synthetic and how these categories cut across the
necessary/contingent one.
But we are not talking these things so why are they being discussed
here? We are talking causal truths. The answer to your questions about
such analytic truths, supposing we had some detailed ones, might turn
out not to be relevant to what we are discussing.
What can I say that I have not already said? Everything important is
what is left. We can talk till the cows come home about meaning. But in
the end, there are questions about the world itself. Hume, I keep
mentioning him because you have a familiarity with him, was interested
in more than the meaning of words. I think this is a fine tradition and
however I admire Wittgentein, I do not think like his disciples thought,
that philosophy is about clearing up conceptual confusions by attending
to our language.
But that is an analysis of grammar-- of how we use the word "causes"--
not of the nature of the world.
Why would you say or think this? What is common between two things in
the world outside language is in the world outside language, it is not
something in language. And most certainly is not to do with just grammar.
I am not disputing that sentences are true because of both the meanings
of the words and the way the world is. But we do make a distinction. And
causal relations between matches and fire are not part of our language,
they are part of the world outside language.
[...]
Well, I would be very surprised if true sentences did not correspond to
or represent aspects of the world. You are right to raise this and I
will admit that hardly any part of philosophy is unconnected with all
the other parts.
I'm happy to say that "A causes B" corresponds to a state of affairs in
the world if it is true.
But I don't see why we need to say that the world has a nature in
respect to causation or that we are referring to that nature when we
state a cause.
If you don't agree that the world does not have a nature in respect of A
causing B, then how is this different to denying that A caused B?
4. A caused B
is true because something in the world makes it true and it ain't that A
and B are hanging around looking pretty. And, not believing Hume, I
think it is something more than that B follows A.
It is easy to suppose that if you are not happy with what scientists say
about A and B and ask further questions, you must be asking about
meaning or grammar or concepts. But this is a deep mistake and a bad
legacy from Wittgenstein later writings.
The answer to these concerns about causality lies in more than mere
meaning or grammar, it lies in a good look at human theory building and
human representation of the world and ultimately what the best theory
about the world is.
Isn't that the whole reason you brought up the distinction between
meaning and reference in the first place? So that we can resolve
paradoxes by showing that name-like phrases don't always have to be used
to refer to anything?
I would not have said so. I am quite happy to discuss only those
sentences that never fail to have references. Look at 4 above. I am
saying we get nowhere by peering closely at the meaning of the phrases
to identify A or B and we get no real knowledge by asking what do we
mean (English mean) by "caused". What we do get by the latter is further
semantic equivalences. I have argued that the counterfactuals are
crucial in this. That is the meaning part done. The rest is about the
references, about the world out there. The counterfactual version of the
meaning obviously sets the stage for a theory about what is out there
that has tempted the other worlds hypothesis.
I concede that the world out there might include features about human
theory building activities but this something, by no stretch of the
imagination, can be called examining the meaning of our English words.
In most sentences causal nexus don't even look like name-like phrases
anyway.
[...]
Well, this looks wrong to me. What you call formalization, if you are
thinking of the analysis of counterfactuality, never mind causality
for now, never mind necessary statements, is fleshing out details and
overcoming intricate objections to a clear program and question. What
makes a counterfactual true? It is not the truth of the antecedent,
nor of the consequent. So what is it outside human minds that makes it
true? And his answer is the worlds that exist outside human minds.
The purpose of this exertion seems to be to preserve the formalism: we
want all true statements to be made true by things in worlds. So we
invent more worlds.
Formalism? He goes into things. He tries to be as rigorous as possible.
We have not been discussing modal logic here.
I'm not saying it's not an ingenious solution, just that you have to ask
what problem it is a solution to.
Why do all true statements have to be made true by things in worlds in
the first place?
It would be a funny thing if something alleged to be true about the
world turned out to be true but nothing in the world made it true. That
is not something I can imagine even as magic.
And his answer is the worlds that exist outside human minds. He
believed in them, they were not idle speculations for him. Might seem
curious to some folk. But intelligent folk do believe in things others
find extraordinary.
Indeed. Hume had the same problem:
"I am first affrighted and confounded with that forelorn solitude,
in which I am placed in my philosophy, and fancy myself some strange
uncouth monster, who not being able to mingle and unite in society,
has been expelled all human commerce, and left utterly abandoned and
disconsolate. Fain would I run into the crowd for shelter and
warmth; but cannot prevail with myself to mix with such deformity. I
call upon others to join me, in order to make a company apart; but
no one will hearken to me. Every one keeps at a distance, and dreads
that storm, which beats upon me from every side. [...]"
That is a nice quote! I wonder how many of us have felt a bit this way?
