Full Idea
Chalmers' two-dimensional conceivability account of possibility offers a defence of a priori conceptual analysis, and foundations on which a priori philosophy can be furthered.
Gist of Idea
If 2-D conceivability can a priori show possibilities, this is a defence of conceptual analysis

A Reaction
I think I prefer Williamson's more scientific account of possibility through counterfactual conceivability, rather than Chalmers' optimistic a priori account. Deep topic, though, and the jury is still out.
