This paper critiques Modal Realism by exploring its methodological issues, especially concerning the definition and relevance of objects in logical sentences. It discusses the implications of assigning definite values to terms beyond logic, the relative nature of truth, and the overarching concepts of relevance and reality in the context of formal logic. The analysis suggests that traditional approaches may rely too heavily on nouns and logical correspondence, advocating instead for a view that sees relationships and conditionalism as central to understanding reality and truth.

According to actualism, modal reality is constructed out of valuations (combinations of truth values for all propositions). According to possibilism, modal reality consists in a set of possible worlds, conceived as independent objects that assign truth values to propositions. According to possibilism, accounts of modal reality can intelligibly disagree with each other even if they agree on which valuations are contained in modal reality. According to actualism, these disagreements (possibilist disagreements) are completely unintelligible. An essentially actualist semantics for modal propositional logic specifies which sets of valuations are compatible with the meanings of the truth-functional connectives and modal operators without drawing on formal resources that would enable us to represent possibilist disagreements. The paper discusses the availability of an essentially actualist semantics for modal propositional logic. I argue that the standard Kripkean semantics is not essentially actualist and that other extant approaches also fail to provide a satisfactory essentially actualist semantics. I end by describing an essentialist actualist semantics for modal propositional logic. 1 Two Conceptions of Modal Reality In his paper, BTheories of Actuality^, Robert Adams provides a characterization of the debate between actualism and possibilism regarding possible worlds. Possibilism, on Adams's characterization, is the view that there are nonactual possible worlds and that the notion of a possible world is not to be analyzed in terms of actual things. (Adams 1974: 224) Actualism, on the other hand,
Most philosophers who advocate Scientific Realism (SR) endorse also Modal Realism (MR), i.e., assume commitments with objective modality. However, the precise relationship between these positions has been scarcely explored. In this paper I argue that there is an indirect implication from SR to MR. Although the basic thesis of SR does not imply MR, both the main argument for SR and the best realist theory of reference do imply modal commitments.

In this paper, I claim that two ways of defining validity for modal languages (“real-world” and “general” validity), corresponding to distinction between a correct and an incorrect way of defining modal valid- ity, correspond instead to two substantive ways of conceiving modal truth. At the same time, I claim that the major logical manifestation of the real- world/general validity distinction in modal propositional languages with the actuality operator should not be taken seriously, but simply as a by-product of the way in which the semantics of such an operator is usually given.

Modal realists face a puzzle. For modal realism to be justified, modal realists need to be able to give a successful reduction of modality. A simple argument, however, appears to show that the reduction they propose fails. In order to defend the claim that modal realism is justified, modal realists therefore need to either show that this argument fails, or show that modal realists can give another reduction of modality that is successful. I argue that modal realists cannot do either of these things and that, as a result, modal realism is unjustified and should be rejected.

An intuitive objection to modal realism is that merely possible worlds and their inhabitants seem to be irrelevant to an analysis of modality. Kripke originally phrased the objection in terms of being concerned about one’s modal properties without being concerned about the properties one’s other-worldly counterparts have. The author assesses this objection in a variety of forms, and then provides his own formulation that does not beg the question against the modal realist. Finally, the author considers two potential answers to the objection so understood and concludes that only one of them has a chance of succeeding.

It is a commonsense thesis that unactualized possibilities are not parts of actuality. To keep his modal realism in line with this thesis, David Lewis employed his indexical account of the term “actual.” I argue that the addition of counterpart theory to Lewis’s modal realism undermines his strategy for respecting the commonsense thesis. The case made here also reveals a problem for Lewis’s attempt to avoid haecceitism.

sets himself the task of formulating a conception of modal realism which is distinct from the (objectual) modal realism of David Lewis.* That is to say that his goal is to isolate an interesting and substantive sense in which modal judgements might be held to be objective, other than the sense which consists in their having truth-conditions requiring the existence of possible but non-actual worlds. This is the context in which McGinn discusses and endorses a thesis of the supervenience of the modal on the a~t u a l .~ In this paper, my aim is to criticize three elements of that discussion of modal-actual supervenience viz: (I) It contains an erroneous attribution to Putnam of the denial of modal-actual supervenience; (11) There are serious problems concerning the application of a thesis of supervenience to the modal-actual case and none of these are considered; and most importantly, (111) It contains the quite implausible claim that the affirmation of modal-actual supervenience is constitutive of non-objectual modal realism.
