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)

Serious actualism is the view that it is metaphysically impossible for an entity to have a property, or stand in a relation, and not exist. Fine (1985) and Pollock (1985) influentially argue that this view is false. In short, there are properties like the property of nonexistence, and it is metaphysically possible that some entity both exemplifies such a property and does not exist. I argue that such arguments are indeed successful against the standard formulation of serious actualism. (...) However, I also argue that we should distinguish a weaker formulation of serious actualism using the actualist distinction between truth in, and truth at, a possible world. This weaker formulation is then shown to be consistent with the existence and possible exemplification of properties like the property of nonexistence. I end with a novel argument for the truth of the weaker formulation. (shrink)

In what follows, I present only part of a program that consists in developing a version of actualism as an adequate framework for the metaphysics of intentionality. I will try to accommodate in that framework suggestions found in Kripke’s works and some positions developed by Amie Thomasson. What should we change if we accept “fictional entities” in the domain of the actual world? Actualism is the thesis that everything that exists belongs to the domain of the actual world (...) and that there are no possibilia. I shall defend that there are abstract artefacts, like fictional characters, and institutions. My argument could be seen as a version of Moore’s paradox: it is paradoxical to say: “I made it, but I do not believe it exists”. Moreover, there are true sentences about them. I will examine what it means to include abstract artefacts in the domain of the actual world. I favour a use of “exist” that includes beings with no concrete occupation of tri-dimensional space; to exist, it is enough to have been introduced at some moment in history.artefacts, like fictional characters, exist in that sense. I argue that it is important to distinguish two perspectives in order to clarify the kind of knowledge we have of fictional characters. However, their existence presupposes a relation of dependence to a material basis and the mental activities of many people. (shrink)

Serious actualism is the prima facie plausible thesis that things couldn’t have been related while being nothing. The thesis plays an important role in a number of arguments in metaphysics, e.g., in Plantinga’s argument for the claim that propositions do not ontologically depend on the things that they are about and in Williamson’s argument for the claim that he, Williamson, is necessarily something. Salmon has put forward that which is, arguably, the most pressing challenge to serious actualists. Salmon’s objection (...) is based on a scenario intended to elicit the judgment that merely possible entities may nonetheless be actually referred to, and so may actually have properties. It is shown that predicativism, the thesis that names are true of their bearers, provides the resources for replying to Salmon’s objection. In addition, an argument for serious actualism based on Stephanou, 219–250 2007) is offered. Finally, it is shown that once serious actualism is conjoined with some minimal assumptions, it implies property necessitism, the thesis that necessarily all properties are necessarily something, as well as a strong comprehension principle for higher-order modal logic according to which for every condition there necessarily is the property of being a thing satisfying that condition.

Aristotelian Actualism is the conjunction of the theses that absolutely everything is actual, that individuals are neither reducible to nor dependent on independently identified properties, and that some individuals are genuine contingent existents. Robert Adams and Gregory Fitch, two prominent proponents of Aristotelian Actualism, have argued that this view has a consequence that any modal logic stronger than M, and so any modal logic in which symmetry and reflexivity are frame conditions, is inadequate. We argue that this is (...) incorrect. (shrink)

Serious actualists take it that all properties are existence entailing. I present a simple puzzle about sentence tokens which seems to show that serious actualism is false. I then consider the most promising response to the puzzle. This is the idea that the serious actualist should take ordinary property-talk to contain an implicit existential presupposition. I argue that this approach does not work: it fails to generalise appropriately to all sentence types and tokens. In particular, it fails to capture (...) the right distinctions we ought to make between what I call _typographical sentence types_—an interesting and previously undiscussed class of fine-grained sentence types which are partially individuated by their typography, or how they look when written out.

Actualism is a widely-held view in the metaphysics of modality that arises in response to the thesis of possibilism, the doctrine that, in addition to the things that actually exist — in particular, things that exist alongside us in the causal order — there are merely possible things as well, things that, in fact, fail to be actual but which could have been. The central motivation for possibilism is to explain what it is about reality that grounds such intuitively (...) true propositions as that Wittgenstein (who was childless) could have had children. In answer, possibilists argue that we must simply broaden our understanding of reality, of what there is in the broadest sense, beyond the actual, beyond what actually exists, so that it also includes the merely possible. In particular, says the possibilist, there are merely possible people, things that are not, in fact, people but which could have been. So, for the possibilist, the proposition that Wittgenstein could have had children is grounded in the fact that, among the possibilia, there are those that could have been his children. Actualism is (at the least) the denial of possibilism; to be an actualist is to deny that there are any possibilia. Put another way, for the actualist, there is no realm of reality, or being, beyond actual existence; to be is to exist, and to exist is to be actual. This article investigates the origins and nature of the debate between possibilists and actualists, with a particular focus on the implications of the debate for quantified modal logic. -/- .

According to actualism, an agent ought to φ just in case what would happen if she were to φ is better than what would happen if she were to ~φ. We argue that actualism makes a morally irrelevant distinction between certain counterfactuals, given that an agent sometimes has the same kind of control over their truth-value. We then offer a substantive revision to actualism that avoids this morally irrelevant distinction by focusing on a certain kind of control (...) that is available to an agent. Finally, we show how this revised view has two additional advantages over actualism. (shrink)

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.

Actualism is the thesis that necessarily, everything that there is exists. Serious actualism is the thesis that necessarily, no object has a property in a world in which it does not exist. Let's call the claim that actualism entails serious actualism the Entailment Thesis (ET). In this paper I will improve upon a previous argument of mine for (ET). I will then consider the prospects for defending a similar thesis in the temporal realm—the thesis that presentism (...) entails serious presentism. (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.

Suppose we believe that God created the world. Then surely we want it to be the case that he intended, in some sense at least, to create THIS world. Moreover, most theists want to hold that God didn't just guess or hope that the world would take one course or another; rather, he KNEW precisely what was going to take place in the world he planned to create. In particular, of each person P, God knew that P was to exist. (...) Call this the "standard" conception. Most theists find the standard conception appealing. Unfortunately, the view seems to conflict with the equally appealing idea — call it "temporal actualism" — that there are no "future" individuals beyond those that already exist in the present moment. For, on this view, for any historical person P, prior to creation, there was no such person as P and hence nothing about P for God to know. Hence, in particular, God couldn't have known that P was to exist. This is of course not a new problem. But past solutions to it are highly problematic. In this paper, after canvassing previous approaches, I will propose a solution that seems to preserve both temporal actualism and a suitably robust form of the standard conception while avoiding the pitfalls of the past.

Actualism is the doctrine that the only things there are, that have being in any sense, are the things that actually exist. In particular, actualism eschews possibilism, the doctrine that there are merely possible objects. It is widely held that one cannot both be an actualist and at the same time take possible world semantics seriously — that is, take it as the basis for a genuine theory of truth for modal languages, or look to it for insight (...) into the modal structure of reality. For possible world semantics, it is supposed, commits one to possibilism. In this paper I take issue with this view. To the contrary, I argue that one can take possible world semantics seriously without any commitment to possible worlds or possibilism and hence remain in full compliance with actualist scruples. Moreover, one can do so without without invoking either "ersatz" worlds or haecceities. (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)

Actualism is the view that only actually existing things exist. Presentism is the view that only presently existing things exist. In this paper, I argue that being an actualist without also being a presentist is not as easy as many philosophers seem to think. A common objection to presentism is that there is an unavoidable conflict between presentism and relativity theory. But actualists who do not wish to be presentists cannot point to this relativity objection alone to support their (...) position. Unless they have some antecedent reason for thinking that actualism is more plausible than presentism, anyone who is moved by the relativity objection to give up presentism should be moved by a related objection to give up actualism as well. If there is a reason to be an actualist without also being a presentist, it must go beyond the relativity objection to presentism. (shrink)

While morality prohibits us from creating miserable children, it does not require us to create happy children. I offer an actualist explanation of this apparent asymmetry. Assume that for every possible world W, there is a distinct set of permissibility facts determined by the welfare of those who exist in W. Moral actualism says that actual-world permissibility facts should determine one's choice between worlds. But if one doesn't know which world is actual, one must aim for subjective rightness and (...) maximize expected actual-world permissibility. So, because one should expect actual people to be worse off than they could have been if one creates a miserable child, creating a miserable child is subjectively impermissible. And because one should expect actual people to be at least as well off as they could have been if one fails to create a happy child, failing to create a happy child is subjectively permissible.

The actualism/possibilism debate in ethics is about whether counterfactuals of freedom concerning what an agent would freely do if they were in certain circumstances even partly determines that agent’s obligations. This debate arose from an argument against the coherence of utilitarianism in the deontic logic literature. In this chapter, we first trace the historical origins of this debate and then examine actualism, possibilism, and securitism through the lens of consequentialism. After examining their respective benefits and drawbacks, we argue (...) that, contrary to what has been assumed, actualism and securitism both succumb to the so-called nonratifiability problem. In making this argument, we develop this problem in detail and argue that it’s a much more serious problem than has been appreciated. We conclude by arguing that an alternative view, hybridism, is independently the most plausible position and best fits with the nature of consequentialism, partly in light of avoiding the nonratifiability problem.

This article describes the recent reception of Giovanni Gentile and his doctrine of actualism, describing the philosopher's rehabilitation as a major Italian thinker and actualism as a provocative account of socially situated consciousness. The discussion then turns to the future of Gentile studies, focusing on ways in which the ahistorical methods of analytic philosophy might help restore actualism and its author to their proper place in the philosophical canon.

Karen Bennett has recently argued that the views articulated by Linsky and Zalta (Philos Perspect 8:431–458, 1994) and (Philos Stud 84:283–294, 1996) and Plantinga (The nature of necessity, 1974) are not consistent with the thesis of actualism, according to which everything is actual. We present and critique her arguments. We first investigate the conceptual framework she develops to interpret the target theories. As part of this effort, we question her definition of ‘proxy actualism’. We then discuss her main (...) arguments that the theories carry a commitment to actual entities that do not exist. We end by considering and addressing a worry that might have been the driving force behind Bennett’s claim that Linsky and Zalta’s view is not fully actualistic. (shrink)

To understand the thesis of actualism, consider the following example. Imagine a race of beings — call them ‘Aliens’ — that is very different from any life-form that exists anywhere in the universe; different enough, in fact, that no actually existing thing could have been an Alien, any more than a given gorilla could have been a fruitfly. Now, even though there are no Aliens, it seems intuitively the case that there could have been such things. After all, life (...) might have evolved very differently than the way it did in fact. So in virtue of what is it true that there could have been Aliens when in fact there are none, and when, moreover, nothing that exists in fact could have been an Alien? So-called "possibilists" offer the following answer: ‘It is possible that there are Aliens’ is true because there are in fact individuals that could have been Aliens. At first blush, this might appear directly to contradict the premise that no existing thing could possibly have been an Alien. The possibilist's thesis, however, is that existence, or actuality, encompasses only a subset of the things that, in the broadest sense, are. So for the possibilist, ‘It is possible that there are Aliens’ is true simply in virtue of the fact that there are possible-but-nonactual Aliens, i.e., things that could have existed (but do not) and which would have been Aliens if they had. Actualists reject this answer; they deny that there are any nonactual individuals. Thus, actualism is the philosophical position that everything there is — everything that can in any sense be said to be — exists, or is actual. (shrink)

How is what an agent ought to do related to what an agent ought to prefer that she does? More precisely, suppose we know what an agent’s preference ordering ought to be over the prospects of performing the various courses of action open to her. Can we infer from this information how she ought to act, and if so, how can we infer it? One view (which, for convenience, I will call ‘actualism’) is that an agent ought to  (...) just in case she ought to prefer the prospect of her -ing to the prospect of her not -ing. Another view (which, for convenience, I will call ‘possibilism’) is that an agent ought to  just in case she ought to prefer the prospect of some maximally specific option that involves her -ing to the prospect of any maximally specific option that does not involve her -ing (with the quantifiers appropriately restricted). After making some preliminary clarifications in part 1, I will discuss actualism and possibilism in parts 2 and 3, respectively. I will argue, in part 2, that actualism is very far from the truth. And I will argue, in part 3, that while the standard version of possibilism faces significant problems, there are much better versions of possibilism that avoid the objections to the standard view. Ultimately, however, I will argue that even the best forms of possibilism are not acceptable. Then, in part 4, I will propose what I take to be the best view, one that is neither strictly possibilist nor actualist, and that avoids the shortcomings of both these views. (shrink)

Considering the importance of possible-world semantics for modal logic and for current debates in the philosophy of modality, a phenomenologist may want to ask whether it makes sense to speak of “possible worlds” in phenomenology. The answer will depend on how "possible worlds" are to be interpreted. As that latter question is the subject of the debate about possibilism and actualism in contemporary modal metaphysics, my aim in this paper is to get a better grip on the former question (...) by exploring a Husserlian stance towards this debate. I will argue that the phenomenologist’s way to deal with the problem of intentional reference to mere possibilia is analogous to the actualist’s idea of how “possible worlds” are to be interpreted. Nevertheless, I will be pointing to a decisive difference in the metaphilosophical preconditions of what I call "phenomenological actualism" and analytical versions of actualism. (shrink)

Hardcore actualism (HA) grounds all modal truths in the concrete constituents of the actual world (see, e.g., Borghini and Williams (2008), Jacobs (2010), Vetter (2015)). I bolster HA, and elucidate the very nature of possibility (and necessity) according to HA, by considering if it can validate S5 modal logic. Interestingly, different considerations pull in different directions on this issue. To resolve the tension, we are forced to think hard about the nature of the hardcore actualist's modal reality and how (...) radically this departs from possible worlds orthodoxy. Once we achieve this departure, the prospects of a hardcore actualist validation of S5 look considerably brighter. This paper thus strengthens hardcore actualism by arguing that it can indeed validate S5–arguably the most popular logic of metaphysical modality–and, in the process, it elucidates the very nature of modality according to this revisionary, but very attractive, modal metaphysics.

This article studies seriously actualistic quantified modal logics. A key component of the language is an abstraction operator by means of which predicates can be created out of complex formulas. This facilitates proof of a uniform substitution theorem: if a sentence is logically true, then any sentence that results from substituting a predicate abstract for each occurrence of a simple predicate abstract is also logically true. This solves a problem identified by Kripke early in the modern semantic study of quantified (...) modal logic. A tableau proof system is presented and proved sound and complete with respect to logical truth. The main focus is on seriously actualistic T, an extension of T, but the results established hold also for systems based on other propositional modal logics. Following Menzel it is shown that the formal language studied also supports an actualistic account of truth simpliciter. (shrink)

Vetter (2015) develops a localised theory of modality, based on potentialities of actual objects. Two factors play a key role in its appeal: its commitment to Hardcore Actualism, and to Naturalism. Vetter’s commitment to Naturalism is in part manifested in her adoption of Aristotelian universals. In this paper, we argue that a puzzle concerning the identity of unmanifested potentialities cannot be solved with an Aristotelian conception of properties. After introducing the puzzle, we examine Vetter’s attempt at amending the Aristotelian (...) conception in a way that avoids the puzzle, and conclude that this amended version is no longer to be considered naturalistic. Potentiality theory cannot be both actualist and naturalist. We then argue that, if naturalism is to be abandoned by the actualist, there are good reasons to adopt a Platonist conception of universals, for they offer a number of theoretical advantages and allow us to avoid some of the problems facing Vetter’s theory.

Particular possibilities -- such as that this particular chair occupy the only vacant corner of my office -- are commonly supposed to depend on what actual things there are and what they are like, whereas general possibilities -- such as that some chair or other occupy some vacant corner or other of some office or other -- are commonly supposed not to be so dependent. I articulate a different conception whereby general possibilities are no less determined by what actual things (...) there are and what they are like than particular possibilities. Ramifications of this approach are highlighted and brought to bear on a problem often raised for actualist essentialism. (shrink)

Actualism is the thesis that necessarily everything that there is exists. Serious actualism is the thesis that necessarily no object has a property in a world in which it does not exist. In this paper I present a new argument from actualism to serious actualism.

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)

We draw out significant consequences of a relatively popular theory of metaphysical modality—branching actualism—for cosmological arguments for God’s existence. According to branching actualism, every possible world shares an initial history with the actual world and diverges only because causal powers (or dispositions, or some such) are differentially exercised. We argue that branching actualism undergirds successful responses to two recent cosmological arguments: the Grim Reaper Kalam argument and a modal argument from contingency. We also argue that branching (...) class='Hi'>actualism affords a response to one popular defense of the classic contingency argument. What results are new difficulties for several cosmological arguments arising from the metaphysics of modality. (shrink)

Already in 1863, Jules Verne knew about Caselli's "pantelegraphy," which was what he described as a "photographic telegraphy, invented during the last century by Professor Giovanni Caselli of Florence."1 Following the mistaken belief that facsimile machines could not been invented until well after the nineteenth century, and wrongly assuming that Caselli was a fictional inventor, merely a figment of Verne's most productive fertile imagination (as such imaginative elements characterize his latter writings), some of Verne's readers mistakenly ascribed to him the (...) discovery of the possibility of the fax machine. They thus committed what I will call soon "a reversed actualist fallacy."In challenging actualist mistakes .. (shrink)

Actualists who believe in possible worlds typically regard them as "abstract" objects of some special sort. For example, Alvin Plantinga takes worlds to be maximal possible states-of-affairs, all of which "exist", as actualism requires, but only one of which "obtains". Views like Plantinga's run into difficulty in the interpretation of statements of "iterated" modality, statements about what is "possible" for individuals that "could" exist but that do not actually exist. These statements seem to require the existence of "singular" states-Of-affairs (...) that have nonactual individuals as constituents, a requirement that is incompatible with actualism. One can try to avoid the troublesome singular states-of-affairs by introducing "unexemplified individual essences" and maintaining that these are the true constituents of the required states-of-affairs, rather than the nonactual possibles themselves. However, serious arguments are raised against this employment of individual essences. (shrink)

This intuition may be contrasted with the incompatible intuitions that might support, say, average utilitarianism. According to average utilitarianism we should bring about that outcome which has the highest average utility. That someone would have a higher than average level of utility is, therefore, ceteris paribus a reason to act so that that person exists. Because of this, the basic intuition is a reason for rejecting average utilitarianism.

This article concerns the prescriptive function of decision analysis. Consider an agent who must choose an action yielding welfare that varies with an unknown state of nature. It is often asserted that such an agent should adhere to consistency axioms which imply that behavior can be represented as maximization of expected utility. However, our agent is not concerned the consistency of his behavior across hypothetical choice sets. He only wants to make a reasonable choice from the choice set that he (...) actually faces. Hence, I reason that prescriptions for decision making should respect actuality. That is, they should promote welfare maximization in the choice problem the agent actually faces. Any choice respecting weak and stochastic dominance is rational from the actualist perspective. (shrink)

The actualism/possibilism debate in ethics concerns the relationship between an agent’s free actions and her moral obligations. The actualist affirms, while the possibilist denies, that facts about what agents would freely do in certain circumstances partly determines that agent’s moral obligations. This paper assesses the plausibility of actualism and possibilism in light of desiderata about accounts of blameworthiness. This paper first argues that actualism cannot straightforwardly accommodate certain very plausible desiderata before offering a few independent solutions on (...) behalf of the actualist. This paper then argues that, contrary to initial appearances, possibilism is subject to its own comparably troubling blameworthiness problem. (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)

Actualists routinely characterize their view by means of the slogan, “Everything is actual.” They say that there aren’t any things that exist but do not actually exist—there aren’t any “mere possibilia.” If there are any things that deserve the label ‘possible world’, they are just actually existing entities of some kind—maximally consistent sets of sentences, or maximal uninstantiated properties, or maximal possible states of affairs, or something along those lines. Possibilists, in contrast, do think that there are mere possibilia, that (...) there are things that are not actual. They think that more exists than what actually exists. All I have done so far, though, is rephrase the slogan in various ways. To say that everything is actual is precisely to say that there are no things that do not actually exist, which is precisely to say that there are no mere possibilia, and which is also precisely to say that we cannot sep- arately quantify over what exists and what is actual. These claims all amount to the same thing. But what is that, exactly? What on earth does it mean to say that everything is actual, that there are no mere possibilia, and so on? What does the actualist slogan really come to? I think the literature is far from clear on this point, and that people work themselves into unnecessary muddles because of it. Indeed, certain confusions that I shall discuss in the first half of this article seem to be on the rise. It is high time to lay out the issues and the choice points as clearly as possible. There are two primary choices to be made; there are two axes along which versions of actualism can vary. One choice has to do with how to treat claims about things that merely could exist. The other choice has to do with the modal status of the view and of how we should think about the “actual” in actualism. I make no claim that the positions I will eventually endorse are star- tlingly new. I think that most people will agree with the decisions I make at both choice points and will in fact find some bits of this essay obvious. But not everyone agrees with my decisions, and it has been my experience that people differ remarkably about which bits they find obvious—a fact I find rather telling. My goal, then, is to show that the two axes are there and to clarify the consequences of the choices. (shrink)

The understanding of Hegel's metaphysics that is here argued for—that it is a metaphysics of the actual world—may sound trivial or empty. To counter this, in part one the actualist reading of Hegel's idealism is opposed to two other currently popular interpretations, those of the naturalist and the conceptual realist respectively. While actualism shares motivations with each of these positions, it is argued that it is better equipped to capture what both aim to bring out in Hegel's metaphysics, but (...) also better able to resist criticisms of each of these opposed positions made from the viewpoint of the other. Like the conceptual realist, the actualist wants to affirm the objectivity of concepts in the world—an idea that can seem antithetical to the naturalist. While the position of “liberal naturalism” makes concessions to such a position, this feature is more easily accommodated by the actualist. However, like the liberal naturalist, the actualist is also suspicious of an implicit “supernaturalist” dimension of conceptual realism and, by weakening the scope of realism to the actual world, is better able to avoid it. The second and third parts of the paper attempt to show how the actualist position is reflected in Hegel's account of judgments and syllogisms in The Science of Logic. His account of judgments provides an irreducible place for judgments that are object-presupposing on the one hand and subject-locating on the other. Because such judgments are the components of syllogisms, these syllogisms have objectivity, but this is a type of objectivity within which we, as subjects, are by necessity located. The actual world has a conceptual structure because we conceptualizing beings belong to it. (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.

Do facts about what an agent would freely do in certain circumstances at least partly determine any of her moral obligations? Actualists answer ‘yes’, while possibilists answer ‘no’. We defend two novel hybrid accounts that are alternatives to actualism and possibilism: Dual Obligations Hybridism and Single Obligation Hybridism. By positing two moral ‘oughts’, each account retains the benefits of actualism and possibilism, yet is immune from the prima facie problems that face actualism and possibilism. We conclude by (...) highlighting one substantive difference between our two hybrid accounts. (shrink)

In recent papers, Philip Swenson (2016) has argued that presentism is incompatible with the conjunction of libertarianism and divine foreknowledge, and Michael Rea (2006) has argued that presentism is incompatible with the conjunction of libertarianism and bivalence. In this paper, I respond to Swenson’s and Rea’s arguments. In each case, I develop a parody argument that seeks to show that actualism -- the view that everything is actual -- is inconsistent with the conjunction of (in the case of Rea) (...) libertarianism and bivalence and the conjunction of (in the case of Swenson) libertarianism and divine foreknowledge. Seeing how these parody arguments using actualism go wrong helps us see how the arguments using presentism go wrong. I conclude that we have not yet been provided with a sound argument that presentism is inconsistent with the conjunction of libertarianism and bivalence or that presentism is inconsistent with the conjunction of libertarianism and divine foreknowledge.

My dissertation consists of three essays in the Metaphysics of Modality: In "A Puzzle about Truth and Singular Propositions," I consider two theses that seem to be true and then an argument for the conclusion that they form an inconsistent pair. One thesis is that a proposition that is singular with respect to a given object implies that the object exists. This is so because the proposition predicates something of the object. The other thesis is that some propositions are true (...) with respect to possible worlds in which they do not exist. An example is the negation of the proposition that Socrates is wise. This proposition is true with respect to possible worlds in which Socrates does not exist, but it does not exist in those worlds. ;In "Actualism, Ontological Dependence, and Possible Worlds," I consider Actualism, the doctrine that every possible object is an actual object. Plantinga has argued that the actualist is committed to the existence of unexemplified essences if he analyzes statements of modality by quantifying over possible worlds and over members of their domains. I argue that the actualist is committed to the existence of unexemplified essences even if he paraphrases statements of modality by quantifying only over possible worlds and actual objects. ;In "Possibilism and the Nature of Actuality," I consider Possibilism, the doctrine that there are possible objects that are not actual objects. Possibilism seems to be a coherent ontological doctrine. It is not Meinong's doctrine that there are objects of which it is true to say that there are no such objects. If one fails to distinguish between these two doctrines, then one's attempt to refute Possibilism might amount to an attack on a blatant contradiction. I illustrate this claim by arguing that the distinction between Possibilism and Meinong's doctrine has eluded Plantinga. I then consider the view that Possibilism is a consequence of Lewis's doctrine that 'actual' is an indexical term. I also argue that the sense in which Lewis said that 'actual' is indexical is an esoteric sense of the word, not a sense it ordinarily has. (shrink)

Bernard Linsky and Edward Zalta have recently proposed a new form of actualism. I characterize the general form of their view and the motivations behind it. I argue that it is not quite new – it bears interesting similarities to Alvin Plantinga’s view – and that it definitely isn’t actualist.

Presentism is the view that only presently existing things exist. Actualism is the view that only actually existing things exist. Although these views have much in common, the position we take with respect to one of them is not usually thought to constrain the position that we may take toward the other. In this paper I argue that this standard attitude deserves further scrutiny. In particular, I argue that the considerations that motivate one common objection to presentism—the grounding objection—threaten (...) to give rise to an analogous grounding objection to actualism. Those who are moved by grounding considerations to give up presentism should either be moved by analogous considerations to give up actualism as well or be prepared to undertake quite a bit of further work in order to defend their position.

Recent scholarship has established that, until the mid-1670s, Leibniz did not hold the possibilist ontology which, in his mature philosophy, provides the foundation for both his account of human freedom and of eternal truth. Concentrating on the Mainz period , this paper examines the conciliation, in those early writings, of an actualist ontology and a conception of necessary truth as analytical. The first section questions the view that Leibniz was educated in a “Platonist” tradition; the second section presents the actualist (...) metaphysics that he adopted in the wake of his teachers; the third section shows how Leibniz could, contrary to those same teachers, hold an analytical view of eternal truth, even without the support of his later possibilist ontology and doctrine of real definitions.

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)
