Full Idea
The one and only way of having a place in an account told in some set of preferred terms is by being entailed by that account - a view I will refer to as the entry by entailment thesis.
Gist of Idea
Something can only have a place in a preferred account of things if it is entailed by the account

A Reaction
How do we distinguish between the original account, which seems to be just accepted, and the additions which accrue because they are entailed by it? Why does this club distinguish members from guests?
