Even if it is granted that one has a firm grasp on the modalist's basic modal and actuality operators, once the subscripts are added and one operator is placed within the scope of others, one has no intuitive grasp of their meanings in those contexts. Thus, warrant for a specific theory of modality depends on deeper considerations about forms of argument appropriate to metaphysics.
The Boethian compromise that Plantinga supports is: Plantinga provides a convincing refutation of this argument, again relying upon the metaphysical machinery he had developed earlier. They make no claims about the empirical world and, so, are not subject to empirical falsification and are either necessarily true or necessarily false.
This is Lewis's counterpart theoryI dare say, achieving such a revision would not be easy. David Hume adopted a kind of noncognitivism about the relation of cause and effect. When one confronts another instance of missing cheese and one has been unable to observe rodents, the inference to the activity of mice might well be appropriate.
We first define two relations among the states of affairs: Armed with these fundamental modal notions, Plantinga investigates some important questions in the philosophy of language. Rudolf Carnap tried to solve this problem by avoiding the semantic foundation of meaning, thus avoiding Quine's critique, and by relying on syntactic facts of grammar and rules of logical proof.
See my The Worlds of Possibility: The concept of state of affairs is used to define what a possible world is. Somewhat more controversial is the idea that there is an intermediate modality between the logical and the natural: Whether fictionalism gains any theoretical advantage over modal realism depends on the content of the operator "according to the fiction of possible worlds.
This essay presents most of the modal concepts of his theory in essentially the form developed in the earlier essays, but now the concepts are presented in a more systematic and perspicuous manner.
Each was concerned with the semantics for proper names and natural kinds terms. How can this account of the truth conditions for modal claims be squared with the often-unstated starting point in the philosophy of modality: Now a state of affairs P is a possible world iff, for every state of affairs S, P either includes S or precludes S.
A set of states of affairs is possible iff it is possible that all of its members obtain. The last of the essays is aimed at showing that propositions cannot be concrete and hence that propositions cannot be the sets of possible worlds that David Lewis claims that they are.
In stating that everything is necessarily or essentially F and that something is necessarily or essentially F, these sentences seem to make metaphysical claims, about which the positivists had succeeded in raising suspicion. Essays in the metaphysics of modality / Alvin Plantinga. New York. ISBN 1.

Perhaps no one has done more in the last 30 years to advance thinking in the metaphysics of modality than has Alvin Plantinga. Collected here are some of his most important essays on this influential subject. It is in the second of these essays that Plantinga introduces what are to become the basic entities of his metaphysics of modality: states of affairs.
States of affairs are held to be abstract entities that such phrases as ’George Bush being a Yale graduate’ and ’Laura Bush having run for the presidency’ refer to.
