I have posted at several blogs with the idea of starting a typological philosophy, "objective coherentism":
In traditional coherentism, statement p is true if it meets conditions S, where S may be contingent.
In Objective Coherentism,
Coherentists are those who hold that for n equivalent statements, organization S is valid when n is ennumerated.
So before a statement is determined to be invalid or subjective, it may be seen that it is either:
A. A difficult claim in a particular organization
B. A difficult claim based on the perfection of evidence
Stated in these terms, coherentism can be a form of objective philosophy.
