-
- Well, I don't know about more definitional, but it is certainly more
- immediatly meaningful.
-
- Given some quite widely shared assumptions about the world, the
- brain-state definition has a well defined interpretation and, although
- we may not be able to decide it because of technological limitations
- or more inherent limitations such as QM, it does seem clear what a
- decision procedure for it might be.
-
- On the other hand, when you start throwing around terms like `possible
- world' and `hold' then you are dragging in a _huge_ raft of auxiliary
- machinery and new assumptions. Then, even if we all agreed just what
- we meant by holding in a possible world, there is no reason to think
- that the equivalence so defined relates to anything interesting in the
- real world.

- [Well, that should get me lynched by any passing semanticists]
