So you apply it to a form where it does hold. The mental model isn't forced into some logician's favorite straightjacket, doomed forever to defy probabilistic analysis because of bad notation. Sheesh.

Sure it makes sense.

Eh? Why not?

I don't use them. In fact, I've repeatedly denied that there are relevant semantics due to the lack of physical correlates.

I've only pointed out repeatedly that this is why I don't bother spelling out more detail. Whatever particular model I consider is wrong.

So what?

I apply it to the base theory, not the limit theory.
