A proposition is true if and only if, in the long run it will come to be accepted by a group of inquirers using scientific rational inquiry.
This can also be modalized: a proposition is true if, and only if, in the long run it would come to be accepted by a group of inquirers, if they were to use scientific rational inquiry.
