This essay is a study of Non-actualism, the thesis that there are objects which do not exist. There are several difficulties surrounding this thesis. First, there is the question about how to make sense of this very thesis. Second, there is the problem about what evidences there are for such a thesis. Third, there is a serious doubt about whether such thesis can be held consistently. ;The first question is usually claimed to be answered by Non-actualists by distinguishing two (...) kinds of quantifiers: existential quantifiers and a "broader" sort of quantifiers. My suggestion in this essay is, however, that there is a more ordinary use of the phrase "there is" which makes the Non-actualist thesis perfectly intelligible. After clarifying what I mean by "Non-actualism", especially after clarifying what the phrase "there is" is used to mean, I go on to check what evidences there are for such a doctrine. In the literature, three different sorts of evidences are usually cited by Non-actualists to defend their positions: fictional talk, modal talk, and our experiences about things not existing. I reject the first two but endorse the last one mainly on the ground that non-actual talk is subject to different interpretations and is only remotely related to ontological issues. However, there still is a threat of inconsistency for those Non-actualists who want to defend their positions from the empirical or phenomenological aspect. In this essay, I distinguish three kinds of paradoxes that a Non-actualist has to solve, and show their independence. I call them, separately, the Sosein Paradox, the Sein Paradox and the Cardinality Paradox. Further, I show that most Non-actualist theories which are designed mainly to solve these paradoxes do not really accomplish their task. But, to our surprise, there is a Meinongian thought which solves these paradoxes quite naturally, even though it did not aim at such a solution when it was developed. And I attribute this theory to Butchvarov. (shrink)

According to hardcore actualism (HA), all modal truths are grounded in the concrete constituents of the actual world. In this paper, I discuss some problems faced by HA when it comes to accounting for certain alleged possibilities of non‐existence. I focus particular attention on Leech (2017)'s dilemma for HA, according to which HA must either sacrifice extensional correctness or admit mere possibilia. I propose a solution to Leech's dilemma, which relies on a distinction between weak and strong possibility. It (...) remains the case, however, that HA cannot capture certain iterated de re possibilities of non‐existence and that it is committed to a stock of necessary existents. But I still think that the virtues of the view outweigh these costs. (shrink)

Actualist counterpart theory replaces David Lewis’s concrete possible worlds and individuals with ersatz worlds and individuals, but retains counterpart theory about de re modality. While intuitively attractive, this view has been rejected for two main reasons: the problem of indiscernibles and the Humphrey objection. I argue that in insisting that ersatz individuals play the same role as Lewisian individuals, actualists commit the particularist fallacy. The actualist should not require stand-ins for every Lewisian individual. Ersatz individuals should instead be construed as (...) representations of actually existing qualitative ways for individuals to be, or qualitative properties individuals can instantiate. This necessitates changes elsewhere. Non-instrumental uses of Kripke semantics and standard counterpart semantics also require stand-ins for particular non-actual individuals. I argue that the actualist should instead adopt a non-standard counterpart semantics that more clearly illuminates the role that actual properties and relations play in explaining de re possibilities and necessities. The result is an intuitive and forceful reply to both the problem of indiscernibles and the Humphrey objection. (shrink)

In On What Matters, Derek Parfit enters the debate between actualists and possibilists. This debate concerns mere possibilia, possible but non-actual things such as golden mountains and talking donkeys. Roughly, possibilism says that there are such things, and actualism says that there are not. Parfit not only argues for possibilism but also argues that some self-proclaimed actualists are, in fact, unwitting possibilists. -/- I argue that although Parfit’s arguments do not fully succeed, they do highlight a tension within the (...) frameworks of many actualists. Many actualists conscript abstract objects into the role of "possible worlds" to avoid quantifying over mere possibilia. But, in doing so, actualists must quantify over mere possibilia anyway. When we alleviate this tension, a Parfit-friendly form of actualism arguably remains. This form of actualism says that while everything that exists is actual, it is also true in some sense that there are mere possibilia. (shrink)

In this article I defend a form of classical possibilism with an actualist foundation. As a matter of fact, I believe that this position is more in keeping with the classical metaphysical tradition. According to this form of possibilism, I construe possible objects as possible non-existing objects of an existing producing power. Consequently, they are nothing vis-à -vis the modality of their own actual being, although they do exist with regard to the modality of the producing power’s being. The actualist (...) requirement prescribed by the Frege-Quinean criterion of the quantification domain is thus fulfilled; indeed, really possible objects are not actual objects, but their possibility is actual.

Robert Adams characterizes actualism regarding possible worlds as «the view that if there are any true statements in which there are said to be nonactual possible worlds, they must be reducible to statements in which the only things there are said to be are things which there are in the actual world, and which are not identical with nonactual possibles.» In this paper, I will briefly explain actualism about possible worlds, showing that an essential pillar of the theory (...) is the claim that truth is distinct from, and ontologically prior to, truth in a world. The rest of the paper is premised on the idea that an interesting philosophical defense of this claim calls for an analysis of truth itself, and is not intended as an objection to actualism, but rather to underscore the interest actualists should have in the question of what truth is. First, I will consider the idea, drawn from Adams and Alan McMichael, that truth differs from truth in a world in its being a matter of correspondence between a proposition and an independent object; that object being, in McMichael's words, the `concrete universe'. Then, I will show that, given such an analysis of truth, the truth conditions for propositions about non-actual possibilities violate the central tenet of actualism, as articulated by Adams.

It has been argued that actualism – the view that there are no non-actual objects – cannot deal adequately with statements involving iterated modality, because such claims require reference, either explicit or surreptitious, to non-actual objects. If so, actualists would have to reject the standard semantics for quantified modal logic (QML). In this paper I develop an account of modality which allows the actualist to make sense of iterated modal claims that are ostensibly about non-actual objects. Every occurrence of (...) a modal operator involves the stipulation of a possible world, and nested modal operators require stipulation of nested possible worlds. I provide an actualistically acceptable (AA) semantics for QML wherein the nesting relation is irreflexive and intransitive and forms a tree. Despite these restrictions, AA models can beshown to be sound and complete for a wide variety of modal logics. (shrink)

It has been alleged that actualism and quantified modal logic are incompatible. My aim in this dissertation is twofold: to defend thoroughgoing actualism with respect to possible objects, and to present a modified semantics for quantified modal logic that is compatible with such a position. The basic strategy is to draw on the parallels between fictions and possible worlds to develop a hierarchical system of worlds-within-worlds ;Actualists usually take first-order modal statements as being about the right objects, by (...) stipulation. Any actualistically acceptable semantics must extend this approach to higher-order modal statements. "I could have had a brother who was a banker but could have been a pianist" means: there is a first-order world in which I have a banker brother, and there exists within that world a second-order world in which that very brother is a pianist. This eliminates the troubling need to identify non-actual objects across worlds of the same order. ;The concept of worlds-within-worlds is analogous to that of consistent fictions-within-fictions. Independent investigations of each concept reveal that both nesting structures are treelike, irreflexive and intransitive. Despite these restrictions, AA models are relatively tractable, being derivable from Kripke models for by unraveling. They are sound and complete for normal propositional modal logics, and for the quantified modal logic Q1R as long as constants are excluded from the language. ;In Chapter 1, I argue for actualism and against some proposed responses to the iterated modality problem. I then present the idea of nested worlds as a solution. Chapter 2 examines the analogous concept of nested fictions, to shed some light on consistent nesting structures. Chapter 3 returns to modality proper; AA models are defined and defended for both propositional and quantified modal logic. Chapter 4 contains the soundness and completeness results, and ends with a somewhat surprising philosophical argument motivated by AA semantics: unless it is metaphysically necessary that all objects have sufficient essences, the correct logic for metaphysical necessity must be weaker than B.

Presentism, some say, is either the analytic triviality that the only things that exist now are ones that exist now or the obviously false claim that the only things that have ever existed or will are ones that exist now. I argue that the correct understanding of presentism is the latter and so understood the claim is not obviously false. To appreciate this one has to see presentism as strictly analogous to anti-Lewisean actualism. What this modal analogue makes evident (...) is that singular tensed statements can have scope ambiguities and so can be thought of as true with the temporal operator represented by the tense read as having wide scope. Secondly, I argue that the analogy with the modal case also makes it clear that presentism must be understood as a thesis of the form: ‘the only things that have ever existed or ever will exist stand in relation R to this utterance’, and is not a substantive topic for debate until relation R is characterized in non-temporal terms. However, despite the strict analogy, I argue that presentism may be a harder position to defend than actualism, since the truth-maker objection, properly interpreted, with Lewis, as based on a supervenience thesis, has more force as an objection to presentism since supervenience is itself a modal notion.

This chapter focuses on two clusters of questions concerning existence. The first cluster concerns the scope of existence, examining how wide the domain of existing things is and whether it encompass absolutely everything. The second cluster concerns vagueness and indeterminacy, explaining whether vague things and vague categories of things are there or all vagueness is a matter of referring indifferently to a large number of absolutely precise things and showing the ultimate source of vagueness. There are two theories of vagueness, (...) epistemic and metaphysical. The chapter focuses on Meinongian definitions of 'existence' and examines four arguments in favor of Anti‐Actualism. The first and second respectively appeals to common sense and the need for intentional objects, that is, objects of certain mental attitudes. The third appeals to the need for fictional and illusory entities. And the fourth appeals to the need for non‐existent things as constituents of certain merely possible situations. (shrink)

The purpose of this article is to provide a non‐contradictory interpretation of sentences such as “Smith's murderer might not have murdered Smith”. An anti‐actualist, two‐dimensional framework including partial functions provides the basis for my solution. I argue for two claims. The modal profile of the proposition expressed by “The F might not have been an F” is complex: at any world where there is a unique F the proposition is true; at any world without a unique F the proposition has (...) no truth‐value; hence, at no world is it false. It remains an open semantic and epistemological question which of the first two kinds of world the actual world is. The semantic method should be based on explicit intensionalization in lieu of actualism. Actualism accords a privileged role to the actual world. Explicit intensionalization places all possible worlds, including the actual one, on an equal footing. Syntactically, a lambda‐bound world variable replaces the actual‐world constant or operator, while the other world variable is existentially bound. (shrink)

Alan mcmichaels has argued that actualism, The view that there are no non-Actual entities, Has a problem with iterated modalities. This paper argues that this is not the case.

In this extended critical discussion of 'Kant's Modal Metaphysics' by Nicholas Stang (OUP 2016), I focus on one central issue from the first chapter of the book: Stang’s account of Kant’s doctrine that existence is not a real predicate. In §2 I outline some background. In §§3-4 I present and then elaborate on Stang’s interpretation of Kant’s view that existence is not a real predicate. For Stang, the question of whether existence is a real predicate amounts to the question: ‘could (...) there be non-actual possibilia?’ (p.35). Kant’s view, according to Stang, is that there could not, and that the very notion of non-actual or ‘mere’ possibilia is incoherent. In §5 I take a close look at Stang’s master argument that Kant’s Leibnizian predecessors are committed to the claim that existence is a real predicate, and thus to mere possibilia. I argue that it involves substantial logical commitments that the Leibnizian could reject. I also suggest that it is danger of proving too much. In §6 I explore two closely related logical commitments that Stang’s reading implicitly imposes on Kant, namely a negative universal free logic and a quantified modal logic that invalidates the Converse Barcan Formula. I suggest that each can seem to involve Kant himself in commitment to mere possibilia. (shrink)

According to possibilism, or non-actualism, fictional characters are possible individuals. Possibilist accounts of fiction do not only assign the intuitively correct truth-conditions to sentences in a fiction, but has the potential to provide powerful explanatory models for a wide range of phenomena associated with fiction (though these two aspects of possibilism are, I argue, crucially distinct). Apart from the classic defense by David Lewis the idea of modeling fiction in terms of possible worlds have been widely criticized. In this (...) article, I provide a defense of a possibilist account against some lines of criticism. To do so, I assume that names for fictional characters are directly referential and a possible-worlds model that accommodates transworld identity. On this background, I argue, it is possible to construct an elegant model of fictional discourse using familiar models of information exchange in ordinary discourse, and I sketch how this model can be used to i) make a natural distinction between fictional and counterfactual discourse, ii) account for creativity, and iii) sustain a natural definition of truth-in-fiction that avoids certain familiar objections to possibilism. Though I set aside questions about the metaphysical commitments of a possible-world interpretation here, there is accordingly reason to think that the battle over possibilist treatments of fiction will have to be fought over metaphysical foundations rather than technical shortcomings.

In this essay I critique a particular reading of Bergson that places an excessive weight on the concept of the ‘virtual’. Driven by the popularity of Deleuze’s use of the virtual, this image of Bergson (seen especially through his text of 1896, Matter and Memory, where the idea is introduced) generates an imbalance that fails to recognise the importance of concepts of actuality, like space or psychology, in his other works. In fact, I argue that the virtual is not the (...) key concept for Bergsonism and that there is a good deal of evidence in Bergson’s other writings, especially those connected with his actualist notion of ‘refraction’, to think of him as a perspectivist philosopher. Moreover, it will be seen that Virtualism resides within an economy of reflection that is subsumed within the broader paradigm of Actualist refraction. Taking these optical metaphors seriously, the virtual becomes a perspectival image seen from an actual position, or rather, an interacting set of actual positions. This interaction is termed ‘virtualization’, denoting the substitution of a substantive conception with a processual one. In the first two parts of the essay, I direct my remarks more towards Deleuzian readings of the actual rather than Deleuze himself (Deleuze is so open about the biases he brings to his reading of Bergson as to be beyond criticism). In the second two sections, I pursue a philosophical argument for the probity of a non-Virtualist position as such within philosophy, based upon the concept of refraction. This is done not only because it is important that we remain open to other readings of Bergson that are not so heavily mediated in one direction, but also in view of the power of refraction as a new concept for reconciling actual modes such as molar identity, the present, and extension, with their virtual opposites.

We argue that Recanati burdens his otherwise salutary “Mental File” account of singular thought with an “Actualist” assumption that he has inherited from the discussion of singular thought since at least Evans, according to which singular thoughts can only be about actual objects: apparent singular thoughts involving “empty” terms lack truth-valuable content. This assumption flies in the face of manifestly singular thoughts involving not only fictional and mistakenly postulated entities, such as Zeus and the planet Vulcan, but also “perceptual inexistents,” (...) e.g., Kanizsa figures, rainbows, words and phonemes, as well as hosts of at best metaphysically problematic “objects,” such as properties, numbers, ceremonies, contracts, symphonies, “the sky,” “the rain.” Indeed, reflection on what seems to be the boundless diversity of “things” about which we seem to be able to have singular thoughts strongly suggests that there may be no general metaphysics of objects, much less “acquaintance” and “epistemically rewarding” relations that would distinguish singular from non-singular thought. We recommend that Recanati and other mental file theorists confine the theory to a metaphysically neutral account of singular thought as specific kind of internally “focused” computational state, and not seek any general account of the relation of thought to reality.

[Draft substantially revised, September 2021] David Lewis acclimated us to talk of “nonactual concreta that exist,” regarding talking donkeys and the like. I shall argue that this was not for the best, and try to normalize a way of describing them as “actual concreta that do not exist.” The basis of this is a defense of the Meinongian thesis “there are objects of which it is true that there are no such objects,” re: fictitious and illusory objects. I first formulate (...) the problem of negative existentials in a novel way, and discuss why this new version is more forceful against anti-Meinongians. Additional data is also pressed against anti-Meinongians--e.g., the truth of ‘Pegasus is imaginary’, and a reading of ‘There actually are illusory objects’ where it comes out true. The Meinongian, in contrast, easily and uniformly explains the same data, by allowing the existence Pegasus, pink elephants, and the like. But contra Meinong, these cases suggest that the nonexistent objects are mind-dependent objects, and I clarify and defend this suggestion from several objections. The resulting Meinongianism is thus “conservative” in that it merely acknowledges the sense in which there are mind-dependent objects, imaginary and illusory objects being prime examples. Of special note, the “ideology” is conservative as well in that the typical Meinongian jargon of “nuclear” or “encoded” properties is paraphrased away. New suggestions about the ontology of abstracta, mere possibilia, and impossibilia are sketched in light of this. Comparisons are also made with Thomasson, Crane, and McGinn, among others. (shrink)

In this dissertation, I develop a metaphysics of powers to ground Dispositionalism, the theory of the source of modality according to which all alethic modal truths are grounded in dispositional properties instantiated in the actual world. I consider a number of key theses that powers metaphysics display, and investigate which can be incorporated in the metaphysical base of Dispositionalism, and how. In the first part I examine the interaction of two core principles of powers ontologies: Directedness, the thesis that powers (...) ‘point at’ their manifestations, and Independence, the thesis that powers can fail to manifest. These two principles are in tension: there is an argument, known as Too Much Possibility, to the effect that they are inconsistent. I examine various strategies to resist the argument. These involve Physical Intentionality, numerical identity between power and manifestation, process ontologies, and platonic universals. I conclude that they are all unsatisfactory. In the second part, I develop a ‘minimal metaphysics of powers’ that is immune from the threat of Too Much Possibility. This involves considering unmanifested manifestations to be akin to Mere Logical Existents. I argue that the best way to avoid the tension at the heart of powers ontologies is to conceive of unmanifested manifestations as non-essentially non-spatiotemporally located entities. I then consider some consequences of minimal metaphysics: I examine which ontological category the manifestations of power can belong to, and what are the prospects of grounding metaphysical, as opposed to natural, modality. Finally, in the third part, I investigate whether further key theses of powers ontologies can be incorporated into the minimal metaphysics. This leads to discuss the relationship of the minimal metaphysics with grounding and dependency relations, the metaphysics of time, the truthmaking principle, and tendential theories of powers.

Non-actualist theories promise straightforward accounts of meaning, truth and reference of fictional discourse but are ostensibly saddled with a Selection Problem, that multiple possible candidates satisfy the role-descriptions associated with names used in fictions and no principled way to distinguish between them; yet if names are referential, there can only be one referent. The problem is often taken to be a serious—even decisive—obstacle for non-actualism, and the aim of this article is to show that the challenge can be met. (...) I suggest that storytellers and authors fix the referents of referential terms they use by arbitrary selecting referents through simple acts of stipulation, and then determine which of the worlds containing the relevant individuals serve as truth-makers for the story by adding properties to the characters. The resulting view of reference is consistent with reasonable, foundational requirements on reference, such as a causal-historical theory, and can moreover be used to support plausible theories of truth in fiction and facilitate elegant models of fiction as a type of discourse.

Time and modality show remarkable similarities. Each of the most discussed theories in philosophy of time finds an analogous counterpart in modal metaphysics, suggesting that the parallel between the two notions is metaphysically deep. This chapter offers a brief overview of their analogies. Section 1 addresses the analogy between presentism and actualism. Section 2 explores the analogy between non-presentist theories and possibilism. Section 3 discusses the analogy between temporal and modal persistence.

Professor Procrastinate receives an invitation to review a book. Best would be to accept it and then write the review. But if he accepts it, he will never get around to writing. And this would be worse than declining. Should he accept? Possibilists say yes, Actualists say no, and I say we need more information. In particular, we lack some information about the level of goodness of the various options. For example, we lack information regarding how much better it would (...) be to accept and write than it would be to decline. In the course of defending my view, I discuss its implications for ethical theory and our everyday actions. (shrink)

In this paper, I begin by outlining two assumptions that are routinely taken for granted in ethical discourse, one of which entails that values have subjective existence. I then consider a causal account of valuational activity offered by Bruce Morito which serves to question the truth of that assumption, and the extent to which that account falls short of overturning it. Finally, in light of that short-coming, I sketch what I characterize as a “quasi-objective theory of value” the truth of (...) which depends upon a non-regularist and non-actualist conception of laws of nature.

The verdicts standard consequentialism gives about what we are obligated to do crucially depend on what theory of value the consequentialist accepts. This makes it hard to say what separates standard consequentialist theories from non-consequentialist theories. This article discusses how we can draw sharp lines separating standard consequentialist theories from other theories and what assumptions about goodness we must make in order to draw these lines. The discussion touches on cases of deontic constraints, cases of deontic options, and cases involved (...) in the so-called "actualism"/"possibilism" debate. What emerges is that there are various interesting patterns relating the different commitments of consequentialism, different principles about obligation and about goodness, and different rules concerning how facts about values determine facts about obligation.

Consider two standard quantified modal languages A and P whose vocabularies comprise the identity predicate and the existence predicate, each endowed with a standard S5 Kripke semantics where the models have a distinguished actual world, which differ only in that the quantifiers of A are actualist while those of P are possibilist. Is it possible to enrich these languages in the same manner, in a non-trivial way, so that the two resulting languages are equally expressive-i.e., so that for each sentence (...) of one language there is a sentence of the other language such that given any model, the former sentence is true at the actual world of the model iff the latter is? Forbes (1989) shows that this can be done by adding to both languages a pair of sentential operators called Vlach-operators, and imposing a syntactic restriction on their occurrences in formulas. As Forbes himself recognizes, this restriction is somewhat artificial. The first result I establish in this paper is that one gets sameness of expressivity by introducing infinitely many distinct pairs of indexed Vlach-operators. I then study the effect of adding to our enriched modal languages a rigid actuality operator. Finally, I discuss another means of enriching both languages which makes them expressively equivalent, one that exploits devices introduced in Peacocke (1978). Forbes himself mentions that option but does not prove that the resulting languages are equally expressive. I do, and I also compare the Peacockian and the Vlachian methods. In due course, I introduce an alternative notion of expressivity and I compare the Peacockian and the Vlachian languages in terms of that other notion. (shrink)

Though there have been productive interactions between moral philosophers and deontic logicians, there has also been a tradition of neglecting the insights that the fields can offer one another. The most sustained interactions between moral philosophers and deontic logicians have notbeen systematic but instead have been scattered across a number of distinct and often unrelated topics. This chapter primarily focuses on three topics. First, we discuss the “actualism/possibilism” debate which, very roughly, concerns the relevance of what one will do (...) at some future time to what one ought to do at present (§2). This topic is also used to introduce various modal deontic logics. Second we discuss the particularism debate which, very roughly, concerns whether there can be any systematic general theory of what we ought to do (§3). This topic is also used to introduce various non-modal deontic logics. Third, we discuss collective action problems which concern the connection between the obligations of individuals and the behavior and obligations of groups of individuals (§4).This topic is also used to discuss formal systems that allow us to study the relationship between individuals and groups. The chapter also contains a general discussion of the relation between ethical theory and deontic logic (§1) and a brief consideration of other miscellaneous topics (§5). (shrink)

An account of non-existing objects called 'classical possibilism', according to which objects that don't actually exist do exist in various other ways, is implemented in a two-dimensional modal logic with non-traditional predication theory. This account is very similar to Priest's, but preserves bivalence and does not endorse dialethism. The power of classical possibilism is illustrated by giving some examples that makes use of a description theory of reference. However, the same effect could also be achieved in a more Millian fashion. (...) It is argued that classical possibilism is ontologically more neutral than is commonly thought, because it allows for the formulation of various forms of reductionism within the object language.

Dualism about possible worlds says that merely possible worlds aren’t concrete objects, but the actual world is concrete. This view seems to be the natural one for ersatzers about merely possible worlds to take; yet one is hard-pressed to find any defenders of it in contemporary modal metaphysics. The main reason is that Dualism struggles with the issue of how merely possible worlds could have been actual. I explain that there are two different Dualist strategies that can be taken to (...) address the problem. Furthermore, one or other of these strategies should be plausible to anyone who accepts both Existentialism—which tells us that the existence of singular propositions depends on what they directly refer to—and Serious Actualism—which tells us that things must exist in order to instantiate properties. Though it has long been ignored, Dualism is a live option. (shrink)

The problem with model-theoretic modal semantics is that it provides only the formal beginnings of an account of the semantics of modal languages. In the case of non-modal language, we bridge the gap between semantics and mere model theory, by claiming that a sentence is true just in case it is true in an intended model. Truth in a model is given by the model theory, and an intended model is a model which has as domain the actual objects of (...) discourse, and which relates these objects in an appropriate manner. However, the same strategy applied to the modal case seems to require an intended modal model whose domain includes mere possibilia. Building on recent work by Christopher Menzel (Synthese 85 (1990)), I give an account of model-theoretic semantics for modal languages which does not require mere possibilia or intensional entities of any kind. Menzel has offered a representational account of model-theoretic modal semantics that accords with actualist scruples, since it does not require possibilia. However, Menzel's view is in the company of other actualists who seek to eliminate possible worlds, but whose accounts tolerate other sorts of abstract, intensional entities, such as possible states of affairs. Menzel's account crucially depends on the existence of properties and relations in intension. I offer a purely extensional, representational account and prove that it does all the work that Menzel's account does. The result of this endeavor is an account of model theoretic semantics for modal languages requiring nothing but pure sets and the actual objects of discourse. Since ontologically beyond what is prima facie presupposed by the model theory itself. Thus, the result is truly an ontology-free model-theoretic semantics for modal languages. That is to say, getting genuine modal semantics out of the model theory is ontologically cost-free. Since my extensional account is demonstrably no less adequate, and yet is at the same time more ontologically frugal, it is certainly to be preferred. (shrink)

(Please note: the main ideas of this paper are restated in revised/developed form in: "On actualist and fundamental public justification in political liberalism" and "Patterns of justification: on political liberalism and the primacy of public justification". Both papers are available from philpapers.) The paper suggests the deep view of Rawls-type public justification as promising, non-ideal theory variant of an internal conception of political liberalism. To this end, I demonstrate how the deep view integrates a range of ideas, views and commitments (...) at the core of political liberalism’s justification structure, including pro tanto justification, full justification, political values and their priority, justificatory neutrality, the role of reasonable comprehensive views, the nature public reasons, the wide view of public political culture, the role of overlapping consensus and political legitimacy, and not least, the status of reflective equilibrium and the Original Position. I then contrast the deep view with Quong’s ideal theory variant if the internal conception, and argue that we should prefer the deep view. Thus, the prospects of political liberalism depend not so much on whether we find ways to make ideal theory relevant for non-ideal purposes. Rather, it depends on whether political liberalism can devise a credible response to the problem of public dogma. (shrink)

According to many actualist theories of modality, possible worlds should be identified with maximal and consistent sets of actually existing propositions called "world-stories". A set of propositions is said to be maximal if and only if for every (actually existing) proposition P , either P or its negation belongs to the set. In my talk, I will claim that this conception of maximality is problematic in case what has to be represented by a world-story is the possible non existence of (...) an actual individual. A representation of the possible non existence of an actual individual is either a representation that "encodes" the explicit information that the individual does not exist or a representation that does not contain any information about the individual in question. The former case corresponds to a world-story A that contains a proposition according to which a certain actually existing object, say O, does not exist, the latter case to a world-story B that simply does not contain any proposition about O. I will claim, however, that the first way is not good for the actualist (had A been the true world-story, something directly about a possible individual would have been true) while the second conflicts with the standard notion of maximality given above. In order to fix this problem, I will first propose to characterize the notion of "actual object that would have existed, had a certain set of propositions been true". I will then recursively define an alternative conception of maximality ("local maximality") that can be applied to world-stories aiming to represent, in an actualist acceptable way, the possible non-existence of an actual object.

RÉSUMÉ: Les actualistes ne partagent pas tous les mêmes intuitions quant aux mondes possibles. Cet article caractérise les intuitions platoniciennes et aristotéliciennes, et explore les conséquences pour l'actualiste d'accepter le platonisme ou l'aristotélisme. Les arguments en faveur de la conception aristotélicienne tiennent la route, mais pour répondre à certains problèmes concernant la vérité des négatives existentielles, l'actualisme aristotélicien doit rejeter l'actualisme des propriétés, c'est-à-dire la conception que seules les entités existantes ont des propriétés. Puisque les entités non existantes ont certaines (...) propriétés, l'actualisme aristotélicien sans actualisme des propriétés est la meilleure approche aux modalités. (shrink)

Recent work in philosophy of language has raised significant problems for the traditional theory of propositions, engendering serious skepticism about its general workability. These problems are, I believe, tied to fundamental misconceptions about how the theory should be developed. The goal of this paper is to show how to develop the traditional theory in a way which solves the problems and puts this skepticism to rest. The problems fall into two groups. The first has to do with reductionism, specifically attempts (...) to reduce propositions to extensional entities-either extensional functions or sets. The second group concerns problems of fine grained content-both traditional 'Cicero'/'Tully' puzzles and recent variations on them which confront scientific essentialism. After characterizing the problems, I outline a non-reductionist approach-the algebraic approach-which avoids the problems associated with reductionism. I then go on to show how the theory can incorporate non-Platonic (as well as Platonic) modes of presentation. When these are implemented nondescriptively, they yield the sort of fine-grained distinctions which have been eluding us. The paper closes by applying the theory to a cluster of remaining puzzles, including a pair of new puzzles facing scientific essentialism. (shrink)

The paper is a critique of the widespread conception of logic as a neutral arbiter between metaphysical theories, one that makes no `substantive’ claims of its own (David Kaplan and John Etchemendy are two recent examples). A familiar observation is that virtually every putatively fundamental principle of logic has been challenged over the last century on broadly metaphysical grounds (however mistaken), with a consequent proliferation of alternative logics. However, this apparent contentiousness of logic is often treated as though it were (...) neutralized by the possibility of studying all these alternative logics within an agreed metalogical framework, typically that of first-order logic with set theory. In effect, metalogic is given the role of neutral arbiter. The paper will consider a variety of examples in which deep logical disputes re-emerge at the meta-level. One case is quantified modal logic, where some varieties of actualism require a modal meta-language (as opposed to the usual non-modal language of possible worlds model theory) in order not to make their denial of the Barcan formula self-defeating. Similarly, on some views the intended model theory for second-order logic can only be given in a second-order metalanguage—this may be needed to avoid versions of Russell’s paradox when the first-order quantifiers are read as absolutely unrestricted. It can be shown that the phenomenon of higher-order vagueness eventually forces fuzzy logical treatments of vagueness to use a fuzzy metalanguage, with consequent repercussions for what first-order principles are validated. The difficulty of proving the completeness of first-order intuitionistic logic on its intended interpretation by intuitionistically rather than just classically valid means is a more familiar example. These case studies will be discussed in some detail to reveal a variety of ways in which even metalogic is metaphysically contested, substantial and non-neutral. (shrink)

This paper raises two problems for plan-expressivism concerning normative judgments about non-corealizable actions: actions which cannot both be performed. First, plan-expressivists associate normative judgment with an attitude which satisfies a corealizability constraint, but this constraint is (in the interpersonal case) unwarranted, and (in the intrapersonal case) warranted only at the price of a contentious normative premise. Ayars (2022) holds that the pair of judgments ‘A should φ’ and ‘B should ψ’ is coherent only if one believes that A can φ (...) while B ψ’s. But this is false. Both Gibbard (2003) and Ayars hold that the pair of judgments ‘A should φ’ and ‘A should ψ’ is coherent only if one believes that A can φ and ψ. But this assumes possibilism. Second, the paper demonstrates, cases involving interpersonal non-corealizability prompt judgments about what multiple agents should do which – contra Gibbard – are not plausibly associated with any planning subject.

These essays, dating from the late 1960's to the present, chronicle the development of Plantinga's thoughts about some of the most fundamental issues in metaphysics: what is the nature of abstract objects like possible worlds, properties, propositions, and such phenomena? Are there possible but non-actual objects? Can objects that do not exist exemplify properties? Plantinga gives thorough and penetrating answers to these and other questions.

In questo articolo, prendo in considerazione i vantaggi e i problemi connessi all’accettazione del pluralismo ontologico di J. Turner e K. Mcdaniel, vale a dire, della tesi secondo la quale vi sarebbero diversi modi di essere (o di esistere) che sono più fondamentali rispetto dall’essere (o all’esistenza) in generale. Nella prima sezione, esamino due problemi per gli attualisti, cioè quei filosofi che affermano che non ci sono entità che non esistono. Nella seconda sezione, valuto i vantaggi del pluralismo ontologico attualista (...) nell’affrontare tali problemi. Tuttavia, nella terza sezione, presento una serie di problemi che invece affliggono il pluralismo ontologico. Infine, nella quarta sezione, difendo l’idea che i pluralisti ontologici non-attualisti (e cioè i meinonghiani) possono meglio far fronte ad alcuni (ma non tutti) di questi problemi. La mia conclusione è che chi intende difendere il pluralismo ontologico, dovrebbe farlo da una prospettiva non attualista. (shrink)

In this article, we will revisit a motivation to consider the advantages of a theory about structured contents over a semantics of possible worlds. We will argue that a structure represents the strategic organization of the content of “p” under conditions in which asserting it does not imply contradictory consequences. These are the winning conditions for the assertion of ‘p’. When ‘p’ is modally sensitive – it can change its winning parameters – knowledge of the structure thus represents the rational (...) point for assertions (about non-actualized realities) that are organized to maximize what can be deduced from ‘p’. In these cases, the known relevant structure is intensional. We will argue that actualist Possible World Semantics, seeking the conversion of intensional knowledge into a de re representation of possible states, pays the price of being blind to structural divergences; it can only poorly explain these structural divergences between non-actual states of information and correlate it with divergence between winning strategies of assertion. Our argument will begin exposing Frege’s legacy; resort to Dummett’s concept of ingredient sense as an alternative to Kripke’s grade two knowledge; and briefly go through a semantic strategy of Stalnaker and Thomason to represent modal statements. In addition to these authors, we will explore the contribution of Russell, Kaplan and Ecthemendy to our argument. (shrink)

In Judgment and Agency, Ernest Sosa argues for a triple-S structure of complete competences that includes, besides the innermost seat competence of the agent, her overall intrinsic condition and the right situational factors for the manifestation of cognitive success to occur. Complete competences are context-sensitive. The question is raised whether epistemic competences are extrinsic or intrinsic dispositional properties, as well as whether knowledge is the manifestation of powers of the actual world or whether it is a matter of what happens (...) in modally close worlds. An ontological background for the context-sensitivity of epistemic competences that is compatible with their intrinsic character is set in the context of a general account of dispositions. An actualist conception of knowledge is also provided. On this view, the modal force of knowledge, far from being captured by non-localized possibilities, is rooted in the directedness of powers. This article, thus, aims at making explicit the ontological underpinnings of knowledge in a way that it is consistent with Sosa’s fully dispositional virtue epistemology. To this end, the constitution of complete competences is placed in a proper perspective. (shrink)

According to de Ronde it was Bohr's interpretation of Quantum Mechanics which closed the possibility of understanding physical reality beyond the realm of the actual, so establishing the Orthodox Line of Research. In this sense, it is not the task of any physical theory to look beyond the language and metaphysics supposed by classical physics, in order to account for what QM describes. If one wishes to maintain a realist position regarding physical theories, one seems then to be trapped by (...) an array of concepts that do not allow to understand the main principles involved in the most successful physical theory thus far, mainly: the quantum postulate, the principle of indetermination and the superposition principle. If de Ronde is right in proposing QM can only be completed as a physical theory by the introduction of `new concepts' that admit as real a domain beyond actuality, then a new ontology that goes beyond Aristotelian and Newtonian actualism is needed. It was already in the early 20th century that misunderstood philosopher Alexius von Meinong proposed a Theory of Objects that admits a domain of being beyond existence-actuality. Member of the so called `School of Brentano', Meinong's concerns were oriented to provide an ontology of everything that can be thought of, and at the same time an intentionality theory of how objects are thought of. I wish to argue that in Meinong's theory of objects we find the rudiments of the ontology and the intentionality theory we need to account for QM's basic principles: mainly the possibility of predicating properties of non-entities, or in other words, the possibility of objectively describing a domain of what is, that is different from the domain of actual existence.

This thesis is a study on the nature of modality in Hegel’s Logic and contemporary modal metaphysics. The thesis has two aims: Firstly, it examines Lewisian modal realism, as well as the post-Lewisian modal metaphysical accounts of modal actualism and modal essentialism in order to reveal that each position appeals to a non-modal foundation to make modal concepts explicit. Each position thus falls under what Hegel regards as pre-critical metaphysics by suggesting a modally unaccountable ground for modal concepts. The (...) very idea of a foundation to modality is problematic because as a foundation, it is necessarily assumed without further justification, and it directs our attention away from the nature of modality itself to its supposed foundations. These non-modal foundational take the form of possible worlds for modal realism, the form of properties for modal actualism and the form of essence for modal essentialism. To eschew foundationalism in modal metaphysics and provide a less questionable basis for modality, the thesis suggests Hegel’s treatment of modality as a viable alternative in virtue of its being free from the concerns stemming from the pre-critical way of doing metaphysics. The thesis situates Hegel in contemporary modal metaphysics by undertaking two types of exposition. By examining Hegel's treatment of essence and property, the thesis will show negatively that essence and property cannot be a foundation for modality, while by examining Hegel’s treatment of modality, the thesis positively proves that modal concepts are analysable and explainable within the domain of actuality, a domain that can only be made explicit by modal determinations. These two expositions provide an idea of a self-sustaining and self-explanatory modal metaphysics without appealing to non-modal foundationalist metaphysical commitments. More precisely, I argue that Hegel’s logical derivation of modal concepts constitutes a Hegelian modal metaphysics, which contains a comprehensive account of modal concepts that does not rely on any non-modal primitive.

Albert Maslow points out that Wittgenstein dedicated a copy of the Tractatus to Morris Schlick with the following sentence: “ Jeder disese Sätze ist der Ausdruck einer Krankheit ” (Each of this propositions is the manifestation of a disease.) We will try to see some of the treatments to see if the remedy is not, in many cases, worse than the disease. Few philosophical texts have so many material surrounding it as the Tractatus, but and at the same time do (...) maintain such a vast spectrum of interpretations. To the point that one can expect every now and then, exegetical revolutions. Like the political ones, they usually burry the past in its way. An example: the appearance in the 1980s of Wittgenstein's Vienna was a fundamental milestone that showed that it is impossible to dissociate the author from the Viennese intellectual environment. However, attempts have been made to present this new approach as the refutation of the rest, falsely equating the Tractatus with continental philosophy in a book that is really weak in terms of elements of symbolic logic and without any expertise in regard to the philosophy of logic of Frege and Russell, which are essential to understand the context of the concepts in the text of the Tractatus itself and the records of the time. A similar case is the new interpretation that was awarded some ten years later by the North American school: they rightly called attention to the neglect of the essential paradox of the Tractatus of having intended to say what is shown. However, the value of this perspective is lost when the book is treated as the work of a postmodern nihilist, an antimetaphysical dialectician. The same can be said of the interpretation of Raymond Bradley, whose praiseworthy efforts to highlight the Tractarian modal element have resulted in an inadequate Leibnizian framing in his work The Nature of All Being (Bradley, 1992). To show an overview, I would broadly follow the outline of Cerezo (1998), adding and extending his taxonomy a bit. I think Cerezo´s outline is accurate and simple. Cerezo does not take into account contextualist readings or, in any case, it isnt her concern in her Lenguaje y Lógica in Wittgenstein's Tractatus. Let us mention among the ways of reading the Tractatus the empiricist perspectives (in classical version, like Russell, or positivist, like those of Shlick and Carnap ), non-empiricist logicists ( Anscombe, Kenny ), Kantian ( Stenius, Coffa ), metaphysical (in actualist variant, Hacker, or positilist Leibnizian, Bradley), continental (such as Janik and Toulmin ), nihilistic ( Diamond and Conant, Ostrow and his dialectical idea ), and MacGuinn 's elucidatory -ecumenical attempt. David Stern (Stern,1998 ) made a stratification that is not incompatible with the one I point out. 1. The logical-atomistic reading ( logical atomist reading ) of Russell ; 2. The reading of logical positivism ( logical positivist reading ) : with the belligerent antimetaphysical charge ; 3. Metaphysical reading ( metaphysical reading ), like Hacker's, with a logically based idea of metaphysics; 4. The irrationalist reading ( irrationalist reading ) that Toulmin and Janik maintain, for example, or Isidro Reguera, where there is pre-eminence of the religious ethic elements; and 5. therapeutic reading ( therapeutic reading ), which poses it as a kind of infinity joke. We are going to add to the list a reading, which we will call a pathological reading. (shrink)

In this paper I shall “draw” a sketch of a version of Meinongian Presentism. After having briefly presented some data that presentists need to explain and three problems that typically affect presentism (the triviality objection, the problem of the reference of true propositions’ constituents that seem to involve merely past and merely future objects, the truthmaking problem), I shall clarify the bases of my theory. First, I shall reject the actualist presentist assumption, according to which there are no things that (...) do not exist now. Secondly, I shall introduce some notions (e.g., the ones of tensed properties and of temporal existence) that will be useful in order to clarify the contrast between eternalist and non-eternalist metaphysical theories of time. Thirdly, I shall define Meinongian Presentism. Finally, I shall try to demonstrate that this version can deal with the aforementioned problems and with the presentist data in a serious and perspicuous way. (shrink)

The Groningen Protocol and contemporary defences of the legalisation of infanticide are predicated on actualism and personism. According to these related ideas, human beings achieve their moral status in virtue of the degree to which they are capable of laying value upon their lives or exhibiting certain qualities, like not being in pain or being desirable to third party family members. This article challenges these notions suggesting that both ideas depend on arbitrary and discriminatory notions of human moral status. (...) Our propensity to sleep, fall unconscious, pass out and so on, demonstrates that we very often exhibit our status as “potential persons.” Our abilities can and do fluctuate. The equal dignity principle, distinguished in turn from both the excesses of vitalism and consequentialism, is analyzed in the context of human rights logic and law. The normalization of non-voluntary euthanasia, via such ad hoc practices as the Groningen Protocol is considered. Substituted ‘consent’ to the euthanasia of infants or others, is scrutinized and the implications of institutionalizing non-voluntary euthanasia in the context of financial, research and political interests are considered. The impact on the medical and legal professions, carers, families and coroners, as well as public attitudes more generally, is discussed. It is suggested that eroding the value of human life carries with it significant destructive and hazardous long-term implications for societies. To elevate some long-term implications whilst ignoring others demonstrates the irrational nature of the effort to institutionalize euthanasia. (shrink)

The system of realist philosophy developed by John Anderson — situational realism — has recently been dismissed as ‘positivist’ by a prominent critical realist. The reason for this dismissal appears not to be the usual list of ideas deemed positivist, but the conviction that situational realism mistakenly defends a form of actualism, i.e. that to conceive of causal laws as constant conjunctions reduces the domain of the real to the domain of the actual. This is, in part, a misreading (...) of Anderson’s philosophy because, contrary to Hume’s constant conjunction account, Anderson viewed causation as pluralistic and non-linear. However, the critical realist charge does point to two important ontological differences between these realist philosophies — a levels-of-reality thesis and the notion of causal powers. Situational realism has always maintained that the arguments for both lead to difficulties that are logically insurmountable. Unfortunately, this is not addressed in the critical realists’ dismissal of Anderson’s philosophy. Regardless of who makes the charge of positivism, it frequently involves inattention to the real character of its target. (shrink)

This paper explores a new non-deflationary approach to the puzzle of nonexistence and its cousins. On this approach, we can, under a plausible assumption, express true de re propositions about certain objects that don’t exist, exist indeterminately or exist merely possibly. The defense involves two steps: First, to argue that if we can actually designate what individuates a nonexistent target object with respect to possible worlds in which that object does exist, then we can express a de re proposition about (...) “it”. Second, to adapt the concept of outer truth with respect to a possible world – a concept familiar from actualist modal semantics – for use in representing the actual world. (shrink)

This dissertation addresses the problem of trans-world identity in possible worlds semantics, and argues that essentialism does not provide a satisfactory solution to it. If one takes possible worlds semantics seriously as a viable elucidation of the logic of the metaphysical modalities, one must also take a realistic stance toward possible worlds. But then, contrary to Kripke, Plantinga, Van Inwagen, and others, there is a problem with trans-world identity; the real problem being, not the problem of identifying individuals across possible (...) worlds, but rather the problem of the theoretical basis for these identifications. Possible worlds semantics presupposes a substantive theory of what constitutes the cross-world continuation or persistence of individuals. Standard formulations of these semantics nevertheless fail to articulate such a theory. Therefore cross-world identifications become inherently problematic. All available solutions to this problem either presuppose non-trivial essentialism or are incoherent. Non-trivial essentialism is the view that there are certain non-identity properties which a given individual has in every world in which it exists but which other possible individuals fail to have in some of the worlds in which they exist. ;But the question of the coherence of essentialism itself is intimately connected with one's views concerning the nature and existence of properties. Three Cantorian paradoxes are adduced, one against individuative essentialism, one against non-trivial essentialism, and one against properties in general. The paradoxes against properties in general and non-trivial essentialism can be avoided only if one eschews a Quine/Goodman view of property existence---the view that any extensionally well-defined class answers to a property---and makes some kind of distinction between natural and artificial properties. Nevertheless such an eschewal does not avoid the paradox of individuative essentialism. Thus essentialism cannot provide a completely adequate theory of trans-world individuation. For although it provides the necessary conditions for the identity of individuals across possible worlds, it does not allow us to identify these individuals on this basis alone. This conclusion precludes actualist solutions to the problem of the individuation of possibilia which quantify over individual essences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:284 HISTORY OF PHILOSOPHY Although this is not the first time that Gentile has been translated into French (a major work of his, L'esprit, acte pur, was published in Paris in 1925), the fact remains nevertheless that his neo-Hegelian system of philosophy fell on deaf ears originally in France, due to the predominance then of Bergsonism and positivi.sm in different areas of French thought. However, as Michele F. Sciacca (...) (another commentator on Gentile) notes in the Preface, the Gentilian system of "actual idealism" should get a better hearing in France from now on, because the widespread interest in Hegel there since 1925 has prepared the ground for its proper reception. The Bibliography, for which Sciacca himself is responsible, includes a section on Gentile's own writings "concerning the national and political formation of Italy" (p. 14); but, significantly enough, those dealing directly with Fascism are all omitted. This omission seems a deliberate attempt to separate Gentile the philosopher from Gentile the Fascist. No matter how understandable psychologically and politically may be the motive here--to have French readers forget that Gentile was the philosopher of Fascism--the attempt itself at bibliographical expurgation, ironically, runs completely counter to the very accent of the Gentilian theory of "pure act" on the unity of thought and action in human experience and history. Rightly or wrongly, Gentile (in sharp contrast to Croce) saw in Fascism the political expression of that unity. As to the secondary sources, the Bibliography again is unnecessarily incomplete, citing as it does only one work in English on Gentile. The anthology closes with a critical note on Gentile's transcendental conception of immortality by the translator (Joseph Moreau), who argues that the "actualistic" philosophy, despite its "religious tone," defeats itself by ending up with an "Epicurean attitude" (p. 324) toward death and the afterlife. PATRICK ROMANELL University o/ Oklahoma Die Tragik in der Existenz des modernen Menschen bei G. Sirnmel. By Isadora Bauer. (Berlin: Duncker und Humblot, 1962. Pp. 94. DM 12.60.) Miss Isadora Bauer's book lends a salutory touch to contemporary philosophical literature, so much of which is abstract and removed from experience. Her treatise, on the other hand, has for its subject matter the human condition, its finitude, and its inescapable tragedy. Georg Simmel, an early twentieth-century philosopher, is less known in this country than he deserves to be. His "Lebensphilosophie," as Miss Bauer points out, although it was influenced by Schopenhauer and Nietzsche, found an original expression through him and foreshadowed in many ways the work of Husserl and the contemporary existential thinkers. Miss Bauer's presentation of Simmel's concept of the tragic is lucid and thorough and manages in a wonderful way to let us see through this one aspect the broad outlines of Simmel 's philosophy as a whole. In Simmel's formulation, life itself, unfolding in tragic antinomy of flux and form, of becoming and being, is the ultimate ground of all tragic conflict. The dynamic life process brings forth all forms and also endangers and destroys them over and over again. The human being encounters these opposites in all aspects of his experience: his existence is tragic at its core. "Moira," the ancient goddess who confronted the Greek hero as an alien power, is in Simmel's modern view of tragedy within man himself. She is the opposition between continuity and discontinuity, the mere stream of events and their form or meaning broken in tragic conflict. At this point, Simmel's dialectics leads to a "third realm," a "more BOOK REVIEWS 285 than" which is both immanent and transcendent, a kind of "coincidentia oppositorum" beyond logic and definition. It is the realm of the "person" within which, although the tragic conflict is not resolved, there arises the free self from whose non-dual perspective the unity and eternity of life are seen. Within this realm the individual gains an illumination the result of which is "amor fad," his free decision to affirm his being. In this act of decision lies the "meaning" and "value" of life. The substance and point of Miss Bauer's book is to show the connection between the metaphysical ground of Simmel... (shrink)

Here I first raise an argument purporting to show that Lewis’ Modal Realism ends up being entirely trivial. But although I reject this line, the argument reveals how difficult it is to interpret Lewis’ thesis that possibilia “exist.” Five natural interpretations are considered, yet upon reflection, none appear entirely adequate. On the three different “concretist” interpretations of ‘exist’, Modal Realism looks insufficient for genuine ontological commitment. Whereas, on the “multiverse” interpretation, Modal Realism acknowledges physical possibilities only--and worse, (assuming either axiom (...) S5 or axiom B) each possibilium ends up as a necessary physical existent. Finally, on the “broadly Actualist” of ‘exist’, Modal Realism is either inconsistent or it mistakenly identifies the unrestricted quantifier with the unrestricted Actualist quantifier. The upshot is that it remains obscure in what non-trivial sense Lewisian possibilia “exist.”. (shrink)
