I guess since no one seems inclined to reply to my earlier post that I'll just
continue
on with a monologue. One of the points of that little thought experiment was to
illustrate that perhaps we ought not to focus exclusively on the differences
between
machines and organisms. After all, most multi celled organisms are machines
that use
all kinds of mechanical systems as part of their physical structure.

I also want to suggest that we can consider the lifeless mechanical computer
brain
implant in some ways as functionally the same as its organic counterpart. By
the same
token, our organic brain implant has some characteristics of a machine including
the
fact that it is not self replicating.

So perhaps we ought not to try so hard to classify all macro physical objects as
"either" machines "or" organisms. These divisions are questions of logical
typing. They
are also relative to both context and level.

The point is that sometimes it is more appropriate to use "and" logic with
logical
typing. In other words, it may be more descriptive to say that machines and
organisms
both differ and are the same. Much depends upon the context and the level we
are
focusing on as we attempt to articulate our point of view. Better understanding
often
comes from combining many points of view.
