I firmly believe that they are strongly related, but I also think
that we should use a lexicon to provide the mappings between them.
Re Peirce: Whatever document we produce should be intelligible to
people who have not been exposed to CS Peirce's opera omnia. I think
that we should consider Peirce's work, but state the distinction in
some form that can be understood without the use of Peirce's
particular jargon (but, of course, with references (and apologies,
if need be)) to CSP.
