Full Idea
Perhaps our best way of understanding names and natural kind terms is that we have apriori access to currently associated reference-fixing criterion, but only a posteriori access to the associated modal profile.
Gist of Idea
Do we know apriori how we refer to names and natural kinds, but their modal profiles only a posteriori?

A Reaction
This is the 'generalized' view of 2D semantics (covering everything, not just modals and indexicals). I know apriori what something is, but only study will reveal its possibilities. The actual world is easy to talk about, but possible worlds are harder.
