I agree with Hal Finney, or at least with the spirit of Hal Finney's
comment. Now, strictly speaking, Charles is right when saying that
a person is not a program (no more that a person is a computer or a
brain or a liver or a material body). Actually I still don't know
what is a person (and that's why I still cannot decide how many
person exist O (like James Higgo said), 1 (as I tend to believe) or
many, as it looks *apparently*.

Much more easy than defining what is a person is to distinguish
type of discourse (like 1 and 3 discourse), and then to reason
about possible such discourses.

The distinction between the brain and the *owner* of the brain is
well explained by Hofstadter and Dennet in Mind's I, when they
show the shortcomings of Searle's Chinese Room argument.

I would say that a person can be seen as a program (or as a 
sequence of programs) once those terms are interpreted in a 
sufficiently immaterial or abstract way.
I guess Finney was not meaning by program a particular electrical
instantiation of a program.
