You can have a formal theory of anything, including subjectivity.
That is, in fact, why I mentioned semiotics because Peirce's
category of Thirdness includes subjectivity as a special case.    (03)

But just sitting down and writing a bunch of axioms is not going
to do anything useful, unless and until you have a fairly good
*informal* theory to begin with.    (04)

If you haven't done so already, please read the debate between
Barry Smith and John Searle.  You can also start by reading the
Wikipedia article about Social Reality, which has pointers to
Searle's book and several others:    (05)

    http://en.wikipedia.org/wiki/Social_reality    (06)

The subject is filled with complex issues, but one of my favorites
is the following quotation from the Wikipedia article:    (07)

We've all seen major whoppers that politicians and theologians
have foisted on the public since antiquity.  And when politicians
work in collusion with theologians, the combination can become
explosive -- literally.    (09)

The first thing that's lacking is an adequate amount of informal
knowledge.  Any mathematician will tell you that if you can't explain
your ideas adequately in your native language, you'll never be able
to state them in any version of mathematics or logic.    (011)

I agree more with David than with Rich.    (013)

That is why I recommended that we do something we know how to do:    (014)

  1. Use informal lexical resources (such as WordNet, for example)
     as a basis for the NLP.    (015)

  2. Develop narrow, special purpose theories for specific problems
     that we know how to solve.    (016)

  3. Develop NLP systems that use the resources of point #1 to relate
     natural languages to the theories of point #2.    (017)

It's possible that if we develop computer systems that can understand
natural languages, we'll be able to use them for many useful projects.    (020)

But I believe that we're going to achieve the goal of a modest level
of understanding by points #1, #2, and #3 above rather than by writing
millions of axioms along the lines of Cyc.  As I said, if you want
to solve a real problem that some paying customer needs to solve,
focus your attention on that problem.  Don't write a bunch of axioms
with the hope that they might someday be useful.    (021)
