Reply to Holden and Lindauer.
In recent postings, I was careful to use terminology like
"universally accepted to be of permanent value"
"almost universally accepted to be of permanent value".
I was referring to work in f.o.m. as opposed to work in philosophy.
What I wrote was obviously true, because of the words
"almost universally accepted".
This doesn't even commit myself to anything but a sociological observation.
E.g., it commits me only to statements such as
"Godel's second incompleteness theorem is almost universally accepted to be
of permanent value"
"Work in philosophy is generally not almost universally accepted to be of
This is NOT the same as
"Work in philosophy is generally almost universally accepted to be of no
Nevertheless, I do hold more than mere sociological positions along these
lines, as you rightly expect.
BUT: my position is a little bit more subtle than what can be characterized
properly in SOUNDBITES.
1. I didn't intend to spend the time to polish up my position, as this would
be a lot of effort - too much for me right now. And I certainly don't want
to get into an extended effort in which I would be compelled to adopt at
least some of the standard methodology of philosophy as opposed to the
standard methodology of f.o.m.!
2. I am talking about
*permanent value in the sense of KNOWLEDGE*, i.e.
Obviously a main point I was making was that all sorts of philosophy, even
more than generally acknowledged, LEADS to permanent-value-as-knowledge.
In fact, it is so USEFUL, that I use it all the time, every day.
3. But I am making a clear distinction between the philosophy (according to
standard methodology) and the
knowledge that it leads to;
the knowledge that comes out of it later.
4. Permanent value? There is an INDIRECT permanent value to philosophy in
its role in the later creation of knowledge that is of
5. What happens to the philosophy? It gets refocused, reworked, reexposited,
in light of the aspects of it that have lead to knowledge - for
presentations by scholars outside philosophy departments.
6. The original texts became of
i) great historical interest;
ii) sometimes great literary value;
iii) possible sources for further developments in the
permanent-value-as-knowledge sense I am talking about.
7. i-iii constitute an entirely different kind of "permanent value" - NOT

Indeed, many classical texts in philosophy have lots of "permanent value" in
this ENTIRELY DIFFERENT sense , entirely different than

nonexistent. Metaphilosophy is distinctly unfashionable, at least in the
philosophical circles I am most in touch with.
I do not think that
is a good primitive, and I don't think that there is enough agreement as to
its meaning among philosophers, let alone nonphilosophers, to be useful. At
least, not without some foundational work.
I have not seen Maddy and Yablo assert the lack of philosophical
significance of Godel's second incompleteness theorem, nor is it apparent to
me just what the relationship is between formalism, semi-formalism, and
interest/disinterest in the Godel second incompleteness theorem
(philosophically, or otherwise).

It is obvious to me that if you really want to say something interesting
about "justification" here, then you have absolutely no choice but to
immerse yourself in the f.o.m. methodology. More precisely, the f.o.m.
methodology, DIRECTED by philosophical thinking.
I don't think for even an instant that it is possible to do something of
along these lines, without being steeped in f.o.m. methodology, and the
ability to expand its scope in novel ways.
Of course, you could try to emulate Wittgenstein in trying to write things
that may have a kind of long term literary, artistic, historical, or
humorous value. Things that may LEAD to something of
partly because of the controversy it creates, that may attract people with
the skills to do something of

But computer scientists care whether a computer will append 1 correctly, and
will respond appropriately (follow a different rule) when the stored program
is "changed". This was a major feat.
The computer is perhaps approximately as dumb as the "student" in the
Wittgensteinian story who has "trouble" "learning" how to append 1
correctly. Nevertheless, the this dumb student, the computer, did in fact
learn. Or so it seems. Want to doubt that? Fine. Should lead to more

So as I said before, after doing this, one would then proceed to do
something with more constraints, about which you would complain less.
And I'm not sure you remember my last posting when I indicated f.o.m.
advances that would help bolster the skeptics. When I have the time and
energy, I display the famous my old card
HAVE GUN WILL TRAVEL.
The antiskeptics would like half the projects, using it against the
skeptics, and the skeptics would like the other half of the projects, using
it against the antiskeptics.
I don't care, since there is a persistent trail of documented

You are wrapped up in philosophical methodology, and do not see its inherent
I DON'T CARE if you don't see its inherent limitations, since you may
generate discussions that lead later to
whether you are interested in or welcome the resulting knowledge or not.

There is a huge give and take development of f.o.m., and undoubtedly much
more to come, connected with notions of truth. You can contribute indirectly
to this my having good discussions of no

The computer has no "idea" what we intended, yet we now - after deep work -
have no trouble communicating with it to get it to do what we want (in
simple situations). This suggests that there is no problem, and it squarely
puts the skeptic on the spot - at least on the spot as far as any nonskeptic

You are perhaps too wedded to standard philosophical methodology to see its
inherent limitations. The whole issue of
in philosophy is up for grabs. In fact, just what philosophy IS in the first
place is up for grabs. Metaphilosophy is in a very poor, almost nonexistent

Some of them may think that. But under that standard - WHICH I THINK IT AN
INAPPROPRIATE STANDARD - the work is extremely unconvincing, as entirely
If philosophers are looking for (rigorous) PROOF of highly nontrivial
matters, they need to incorporate other methodologies. But division of labor
is important. E.g., I would like to compose music of permanent value (not,
at least on face value, as knowledge!), but I had best leave that to other

I am not "philosophically committed" in the sense that I think you mean, and
do not adopt the normal philosophical methodology. Yet the progress in
f.o.m. is INCOMPARABLY clearer than the progress in philosophy, if PROGRESS
is measured in terms of

As I said many times earlier, I distinguish between
"leading to developments of permanent-value-as-knowledge"
"being a development of permanent-value-as-knowledge".
So what I mean is that
1'. Philosophers do not normally engage in the quest for
"permanent-value-as-knowledge", hoping, at most, that it will lead to such
at some future date.
Do you suggest that we pick up the last 5 issues of the Journal of
Philosophy and evaluate the articles strictly in terms of

So Shannon was using the philosophy methodology, and was a normal member of
the philosophy community?
And if I do a Google search on information theory, I will find that some key
explicit findings are generally explicitly credited to philosophers?
This is most interesting, and I will look into it.

I am sure that the FOM list would appreciate an accounting of what you think
are the highlights in philosophy from the last 5 years as far as
together with a detailed list of publications. Start with the last five
years of Journal of Philosophy, and Philosophical Review, perhaps the two
leading philosophy journals today(?).

Give us some examples of clear and/or effective philosophical thinking in,
at least, the writings of contemporary figures in mathematics.
Let us start with the Annals of Mathematics, and Inventiones Mathematicae,
perhaps the two leading mathematics journals in the world today(?). Please
point out which articles in the last 5 years that you regard as most
