RE:  Rick Jelliffe quotable quote on the purpose of schemas
I remember what my first computer science prof taught us in 1971:  "Don't
worry about the formal correctness.  If it runs, it's right.  Let the
computer teach you."

In those days, computers didn't disagree because very few programs written
on one would run on another one.  See what interoperability gets us?  Fire
breathing flesh chomping foot stomping philosophy spouting dragons.

Back to animation where if it runs and is close to the same color, it's
right.

Sounds Aristotelian: Essence and accident?

Tricky ground this. We could spend the next 2500 years debating it.
Territory best not entered by those without formal training in metaphysics
(like me, who has read just about enough to know that here be dragons).
