Actually I didn't. I left the generation of other possibilities as an
exercise to the reader because I thought it was fairly obvious. If not,
let me know.

Not exactly. I'm saying that the circularity of an argument lies on
a continuum. Very tight circularity (e.g. The Bible is true because
it says so in the Bible) is a logical fallacy. But if the circularity
is extremely complex and indirect (like the body of scientific knowledge)
then it is not a logical fallacy (e.g. we know the age of the universe
because we know the speed of light, and the distance of stars, and the
nature of our instruments, and ... thousands if not millions of steps ...
which are eventually, in the long run, self-referential).

I would agree more with your Deconstructionist characterization. Except that
I would say that everything is open to criticism and revision (the pan-
critical rationalist position) instead of saying everything is suspect
(which might seem the same to you but has different connotations for me).
