Reading his 2007 (Verbal Aspect...) publication did not help clear this up, however, going back to his 2008 (Basics) publication, it does seem to be clarified somewhat:
Campbell goes on to provide the following rule to help categorise verbs:If a lexeme is intransitive, it may also be stative. A stative verb is not performed upon an object and describes a state of being. It is not time bound or progressive; it simply is. ... Whether or not a lexeme is stative is decided simply by what the type of action is. (p57)
So it seems to me that Campbell does assert that we should translate "Πᾶν ὁ μεγας τεθνηκεν" as Pan the great is dead, not "Pan the great is dying". What do you think?Is the action performed upon an object?
If no = intransitive.
Does the action describe a state of being?
If yes = stative.
