SUO: Category Theory




[Reposting after 2 hours]

SUO Working Group,

I have restarted my selection of excerpts from
Mac Lane's 'Cat Work Math' on the Ontology List.
This is intended to help with justifying the ways
of IFF to the millions, and is also offerred in
support of whatever 'mysterium coniunctionis'
may be forthcoming with CYC, SUMO, ...,
not to mention the good BUK itself.

We could get a whole lot of mileage out of the first 30 pages or so.
Indeed, just understanding the category-theoretic definition of the
cartesian product, which is the construction that Mac Lane picks for
his introductory example in the first couple of pages, would help
a lot with one of the most common confusions that I have seen out
there in the cobwebbed fields of current (mal-)practices, namely, 
the stubborn error of confusing a relation with one of its tuples.
