Title: Graham Priest (CUNY)
Dialetheic Metatheory:

Given a formal language, a metalanguage is a language which can express,  
amongst
other things, statements about it and its properties. And a metatheory is a
theory couched in that language concerning how some of those notions behave.
Two such notions that have been of particular interest to modern logicians  
(for
obvious reasons) are truth and validity. These notions are notoriously,  
however,
deeply entangled in paradox. A standard move is to take the metalanguage to
be distinct from language in question, and so avoid the paradoxes.
One of the attractions of a dialetheic approach to the paradoxes of self-
reference is that this move may be avoided. One may have a language with
the expressive power to talk about (among other things) itself, and a theory
in that language about how notions such as truth and validity for that  
language
behave. The contradictions delivered by these notions are forthcoming, but  
they
are quarantined by the use of a paraconsistent logic. The point of this  
paper is to discuss this project, the extent to which it has been  
successful, and the places where issues still remain.
