Over the years, a great deal has been written about the ontology of
pizza
(n.d.a/)
It’s a good example, is easy to understand and works surprisingly well
in a tutorial context. It is also comes up surprisingly commonly in the
public sphere as it did last year on BBC News
(n.d.b) The key
point of which is this: the pizza maker argues that you can’t have a
marinara (tomato and garlic) with added mozzarella because a marinara is
pizza rossa which can’t have mozzarella; a margherita (tomato and
mozzarella) with garlic is fine though. Ha, those crazy Italians. I
paraphrase, of course.
