If anything, the executive summaries of logic and category theory are: (03)
logic is the study of reasoning. (04)
category theory is the study of transformations. (05)
Sure a gross oversimplification, but I think in the appropriate
direction for each, and it allows meaningful distinction and
comparison. It might be difficult to extract the above from wikipedia
or other easy online sources, but still it's a start. (06)

There's all sorts of discussion within the ontology community about
identity. Whether the unique name assumption (UNA) holds, inferring
subsumption of one concept by another. (08)

If you're concerned that a particular formalism might be inappropriate
for business transactions, then CT is definitely it. Even
welleducated and, separately, intelligent people have difficulties
with even boolean logic. (010)

There's what magicians do and then there's magic. There's no magic. (012)
