In this article I formulate a skeptical argument against the possibility of adhering to the divine will in a non-accidental way. In particular, my focus in the article is on a widely embraced modal condition of accidentality, according to which non-accidentality has to do with a person manifesting dispositions that result in a given outcome in a modally robust way. The skeptical argument arises from two observations: first, various authors in the epistemology of religion have argued that it is (...) often not possible to reason reliably about religious matters, and second, non-accidentally adhering to a given norm is often associated with reasoning about the requirements of the norm in question in a reliable way. In addition to pointing out the existence of the argument, I outline strategies in which religious thinkers could reasonably challenge it by denying that reliable reasoning about the requirements of divine will is necessary for adhering to it in a non-accidental manner. Hence, I argue that the possibility of non-accidental adherence to the divine will does not depend solely on whether it is possible to reliably reason about what it requires one to do. (shrink)

It is often argued that inferential role semantics (IRS) entails semantic holism as long as theorists fail to answer the question about which inferences, among the many, are meaning-constitutive. Since analyticity, as truth in virtue of meaning, is a widely dismissed notion in indicating which inferences determine meaning, it seems that holism follows. Semantic holism is often understood as facing problems with the stability of content and many usual explanations of communication. Thus, we should choose between giving up IRS, to (...) avoid these holistic entailments, and defending holism against this charge, to rescue IRS. I try to pursue the second goal by analyzing certain patterns of counterfactual reasoning. Wilfrid Sellars and Robert Brandom claim that, to defend IRS, content-constitutive inferences are those counterfactually robust. While it is difficult to assess the goodness of such a view, it nonetheless entails that counterfactually non-robust inferences (which I call “modally ruled out inferences”) are not content-constitutive. If this is true, and if we take certain remarks about the grasp of concepts on board, there is a way to restrict the scope of the holism entailed by IRS to the extent of reshaping problems with the stability of content.

The concordance of results that are “robust” across multiple scientific modalities is widely considered to play a critical role in the epistemology of science. But what should we make of those cases where such multimodal evidence is discordant? Jacob Stegenga has recently argued that robustness is “worse than useless” in these cases, suggesting that “different kinds of evidence cannot be combined in a coherent way.” In this article I respond to this critique and illustrate the critical methodological role that (...) robustness plays as an aim of scientific inquiry.

Philip Pettit has argued that the goods of attachment, virtue, and respect are robust goods in the sense that they require both the actual provision of certain benefits and the modally robust provision of these benefits. He also claims that we value the robustness of these goods because it diminishes our vulnerability to others. I question whether robustness really reduces vulnerability and argue that even if it does, vulnerability reduction is not the reason we value robustness. In (...) place of Pettit’s account, I defend a promotional account of the value of robustness. I argue that we value robustness because it increases the probability we will enjoy a certain kind of benefit. (shrink)

At the center of the debate between contextualist versus relativist semantics for epistemic modal claims is an empirical question about when competent subjects judge epistemic modal disagreement to be present. John MacFarlane’s relativist claims that we judge there to be epistemic modal disagreement across the widest range of cases. We wish to dispute the robustness of his data with the results of two studies. Our primary conclusion is that the actual disagreement data is not consistent with (...) relativist predictions, and so, that the primary motivation for relativism disappears. Our study differs from a related study by Knobe and Yalcin :1–21, 2014) in that we focus directly on the question of genuine disagreement, as opposed to a question about truth or the appropriateness of retraction. Some of our findings agree with theirs about relativism. We uncover new lessons along the way, including that there are widespread situation effects of epistemic modal discourse; idiosyncratic features of the vignettes significantly influencing judgments about epistemic modal disagreement. We reflect with mixed feelings on the prospects for contextualism to accommodate our findings. (shrink)

In the fifth of his John Locke Lectures, Robert Brandom takes up the challenge to define a formal semantics for modelling conceptual contents according to his normative analysis of linguistic practices. The project is to exploit the notion of incompatibility in order to directly define a modally robust relation of entailment. Unfortunately, it can be proved that, in the original definition, the modal system represented by Incompatibility Semantics (IS) collapses into propositional calculus. In this paper I show how IS (...) can be technically amended so to overcome this failure: the required modifications are already known and consist in adapting and including the main notions of Kripke's standard framework of possible worlds. I also show that the modifications do not jeopardize Brandom's original project. (shrink)

In this paper, I argue that not only is metaphysical modal normativism an attractive view but that, as a matter of fact, many of us have, all along, been metaphysical modal normativists of a particular stripe. Namely, we have been the kinds of modal normativists, in the form of counterpart theorists, who are robust realists about possibility simpliciter. Having introduced modal normativism as Thomasson does in Norms and Necessity, I go on to recast it in somewhat (...) different terms. With this re-casting in place we can see that while the view offers a pleasingly deflationary account of metaphysical necessity and possibility it does so only against the backdrop of robust realism about possibility simpliciter. If that is right, then Lewis’ counterpart theory turns out to be a potent version of metaphysical modal normativism. So many of us have, all along, been metaphysical modal normativists, and so much the better for it. (shrink)

It is a core feature of the conception of freedom as non-domination that freedom requires the absence of exposure to arbitrary power across a range of relevant possible worlds. While this modal robustness is critical to the analysis of paradigm cases of unfreedom such as slavery, critics such as Gerald Gaus have argued that it leads to absurd conclusions, with barely-felt constraints appearing as sources of unfreedom. I aim to clarify the demands of the modal robustness (...) requirement, and offer a reinterpretation of its place in the conceptual framework of freedom as non-domination. I illustrate this point through a discussion of low-probability threats of interference which are central to Gaus’s critique, which I term ‘distant threats’. I argue that those committed to robust conceptions of freedom should still be concerned by these kinds of threats, which will sometimes constitute genuine sources of unfreedom. But rather than leading to absurd conclusions, we should instead view them as diagnostic of deficiencies within existing regimes of non-domination. The challenge posed by distant threats of domination to the republican conception of freedom does not prove it implausible, but illustrates some of its most important insights about the social and economic conditions of free status, and the fragility of that freedom.

Many familiar modal claims are clearly made against some set of background assumptions, as when making such claims, we hold fixed certain background truths, and intend to call attention to the fact that the ‘necessity’ in question is an invariable consequence of those truths. Ordinary explanations of particular phenomena that draw upon scientific theories are replete with modal concepts. Necessity plays a yet deeper role in the practice of formulating scientific theories. Alongside the ever increasing constraints of accumulating (...) empirical evidence, theories are always held to the constraint of logical and mathematical consistency. This chapter expresses common philosophical claims concerning the place of modality in scientific explanations that have nonetheless been heavily challenged, especially in the twentieth century. It also considers and criticizes a range of views that stand opposed to robust modal realism. (shrink)

Recently Philip Pettit has claimed that attachment, virtue, and respect are robust goods. Robust goods require not only the actual provision of certain associated ‘thin’ goods, but also the modally robust provision of these thin goods across a range of counterfactual situations. I focus my attention on Pettit’s account of the robust good of love, which, for Pettit, is the modally robust provision of care. I argue Pettit’s account provides neither necessary nor sufficient conditions for love. In place of Pettit’s (...) account, I suggest an alternative account of love that distinguishes loving dispositions from loving actions. (shrink)

Davies argues that the ontology of artworks as performances offers a principled way of explaining work-relativity of modality. Object oriented contextualist ontologies of art (Levinson) cannot adequately address the problem of work-relativity of modal properties because they understand looseness in what counts as the same context as a view that slight differences in the work-constitutive features of provenance are work-relative. I argue that it is more in the spirit of contextualism to understand looseness as context-dependent. This points to the (...) general problem—the context of appreciation is not robust enough to ground modal intuitions about objective entities. In general, when epistemology dictates ontology there is always a threat of anti-realism, scepticism and relativism. Davies also appeals to the modality principle—an entity’s essential properties are all and only its constitutive properties. Davies understands essentiality in a traditional way: a property P is an essential property of an object o iff o could not exist and lack P. Kit Fine has recently made a convincing case for the view that the notion of essence is not to be understood in modal terms. I explore some of the implications of this view for Davies’ modal argument for the performance theory. (shrink)

The H ∞ performance of a class of T-S fuzzy systems with Markovian-jump parameters is analyzed. A state feedback controller is designed for T-S fuzzy systems with Markovian-jump parameters. First, a new modal-dependent Lyapunov function composed of closed-loop functions is constructed, which can fully use system status information. Based on this function, the stability conditions with less conservatism are given by linear matrix inequalities. At the same time, a design algorithm for a state feedback controller is proposed for the (...) Markovian-jump-parameters T-S fuzzy systems, which ensures the system’s stability under the condition of H ∞ − γ performance. Simulation results demonstrate that the mentioned method is accurate and practical. (shrink)

A fundamental question asked in modal logic is whether a given theory is consistent. But consistent with what? A typical way to address this question identifies a choice of background knowledge axioms (say, S4, D, etc.) and then shows the assumptions codified by the theory in question to be consistent with those background axioms. But determining the specific choice and division of background axioms is, at least sometimes, little more than tradition. This paper introduces generic theories for propositional (...) class='Hi'>modal logic to address consistency results in a more robust way. As building blocks for background knowledge, generic theories provide a standard for categorical determinations of consistency. We argue that the results and methods of this paper help to elucidate problems in epistemology and enjoy sufficient scope and power to have purchase on problems bearing on modalities in judgement, inference, and decision making.

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)

The actions of able agents are often reliably successful. I argue that their success may be modally robust along two dimensions. The first dimension helps distinguish the exercise of abilities, which requires local control, from lucky success. The second concerns the global availability of acts: agents with the ability to φ can φ across a variety of circumstances. I introduce a framework that captures the two dimensions and their interaction, and show how it bears on a disagreement about the (...) class='Hi'>modal force the robustness of ability requires: while local control involves a kind of local necessity, global availability does not.

How, if at all, can scientific progress improve our view of the modal facts? According to rationalist approaches to modal epistemology, science has no substantive role: a priori reflection reveals the structure of modal space, and a posteriori science merely locates us within that modal space, by identifying the actual properties and structures instantiated at our world. According to modal naturalist approaches, science provides evidence about the structure of the underlying modal space. In this (...) paper I distinguish four versions of modal naturalism, with science playing an increasingly robust evidential role, and discuss their plausibility. (shrink)

It has been argued within some philosophy of quantum gravity circles that endorsing Lewisian modal metaphysics is incompatible with endorsing the fundamental physical ontology of any quantum gravity theory. Speaking concisely, the unsolvable tension would be between Lewis' metaphysical commitment to the fundamentality of space and time, and the physical lesson of quantum gravity about the disappearance of space and time from the fundamental structure of the world. In this essay I argue against the idea that the tension is (...) unsolvable. The analysis does not apply to quantum gravity in general, but only to the specific perspective delivered by quantum string theory. In the first two sections I describe what I think is the general formal payoff of Lewisian possible worlds semantics, and more importantly the general metaphysical payoff generated by some Lewisian metaphysical applications of that formal framework. Lewisian possible worlds semantics is not among the topics of this essay, still a concise presentation of its basic features is required for a more accurate description of the type of modal metaphysics Lewis delivers by applying that formal machinery. The moral of the story in the first two sections is that an attempt of preserving crucial features of Lewisian modal metaphysics, although endorsing the quantum string theory lesson on spacetime non fundamentality, would be not only possible, but also philosophically worthy in a general sense. Then, section three is divided in three parts. In the first part I summarize some formal tools of the methodology used elsewhere - (Vistarini, Routledge, 2019, chapter 6)- to argue for string theory background independence. More precisely, I briefly re-describe some crucial features of a topological-vector bundle structure there defined on a "space" associated to the theory. Such structure is there shown to carry physical and dynamical information about quantum strings systems supporting the thesis of background independence of quantum strings laws (string theory background independence is not a topic of this essay, and the construction of the full formal structure as well as the full argumentative line can be found in the work cited above). The rationale behind the choice of including these formal tools is explained in the second and third parts of section three: that very same topological-fiber bundle structure associated to string theory, if read differently, is shown to also carry structural properties of the Lewisian metaphysical scheme. More precisely, in the second part of section three I attempt to show that such topological-fiber bundle structure owns a topology which qualifies as a plausible accessibility structure extending the Lewisian similarity accessibility. To avoid confusion, I will denote the extended similarity order with S*, or S*-similarity. The latter has some interesting properties. It is quantitatively describable, and even more interestingly its spectrum of variation is a countable one. Then, insofar Lewisian similarity order can be regained from the S*-similarity, one might say that the latter is a metaphysical accessibility relation underlying the former because "more fundamental". As we will see, the explanation of what "more fundamental" means in this metaphysical context mainly involves the idea that the formal nature of S*-similarity, in particular its property of having a countable spectrum of variation, calibrates a metaphysical similarity that reflects the discreteness of the fundamental quantum nature of reality. The extended modal metaphysics with accessibility structure S*-similarity is informed by quantum string physics. Within the extended scheme, the Lewisian claim "things could have been different in countless ways" (Lewis 1973) is an approximate one because only permitted by ordinary language. As soon as one refines the accessibility structure by using the formal language of quantum string theory, it appears things could have been different in countable ways. But the Lewisian variety of alternative states of affairs can be regained from the underlying countable variety via a specific interpretation of the Humean supervenience thesis, one that changes the metaphysical status of the thesis' content and restricts the thesis' domain of application. Finally, in the third part of section three I attempt to show that the same topological-fiber bundle structure used to extend Lewisian similarity has a bundle component producing the formal scheme for a tentative extension of Lewisian nomological accessibility through the lens of string dualities. This will prove to be a non trivial task, and the Lewisian accessibility structure will be regained from the extended one only partially. Finally, the essay contains two short appendices summarizing two argumentative lines outside the main topic of the essay. They briefly describe different ways in which the non fundamentality of spatiotemporal structures can be found in quantum string theory. These sections can be skipped. Nevertheless, they might contribute to understand more robustly the general view endorsed by this essay, i.e. that there isn't any unsolvable tension between Lewis' commitment to the fundamentality of spatiotemporal relations and quantum gravity's lesson about their non fundamentality. -/- .

In “Naming with Necessity”, it is argued that Kripke’s thesis that proper names are rigid designators is best seen as being motivated by an individual-driven picture of modality, which has two parts. First, inherent in proper-name usage is the expectation that names refer to modally robust individuals: individuals that can sustain modal predications like ‘is necessarily human’. Second, these modally robust individuals are the fundamental building blocks on the basis of which possible worlds should be conceived in a (...) class='Hi'>modal semantics intended to mirror the conceptual apparatus behind ordinary modal talk. The individual-driven picture is distinct from two views inspired by Kripke, direct reference theory and Millianism. The former covers only the first half of the picture, while the latter explicitly gives up on that half even, opting to remain neutral about what expectation expressions impose on the nature of their referents.

Philosophical discussions of mechanisms and mechanistic explanation have often been framed by contrast to laws and deductive-nomological explanation. A more adequate conception of lawfulness and nomological necessity, emphasizing the role of modal considerations in scientific reasoning, circumvents such contrasts and enhances understanding of mechanisms and their scientific significance. The first part of the paper sketches this conception of lawfulness, drawing upon Haugeland, Lange, and Rouse. This conception emphasizes the role of lawful stability under relevant counterfactual suppositions in scientific reasoning (...) across the sciences, in place of traditional conceptions of law that are primarily confined to the physical sciences. It also extends lawful stability beyond verbally or mathematically expressed law-statements, to encompass other ways of conjoining patterns in the world with scientific pattern recognition. The remainder of this paper shows how and why mechanisms constructively exemplify this conception of lawfulness in scientific practice: • Mechanisms are robust, counterfactually stable and inductively projectible patterns, even though they are not exceptionless “laws of nature”. • Mechanistic explanations often take non-verbal forms, which consequently resist philosophical inclinations to semantic ascent, but understanding lawfulness in terms of counterfactually stable pattern recognition accounts for these ways in which scientific understanding outruns the expressive capacities of natural languages; • Mechanisms are sometimes characterized as real patterns in the world, and sometimes as epistemic representations; understanding mechanisms as modal patterns shows why both conceptions are needed, as mutually supportive. • Mechanisms are typically open-ended, and only partially specified, in ways open to and directive toward further articulation and revision. Understanding mechanisms as modal patterns incorporates this aspect of mechanistic understanding within a broader conception of scientific understanding as embedded in research practice, rather than in bodies of knowledge extracted from it. • Mechanistic explanation has often been placed on the causal side of an opposition between causal and nomological explanation, but understanding mechanisms as modal patterns helps overcome that opposition, and contributes to a pluralist conception of causal relations and their characteristic forms of counterfactual invariance. • The recognition of mechanisms as modal patterns allows for a new way to think about the relations among distinct levels of a mechanistic hierarchy, and the broader scientific significance of mechanistic understanding.

Several recent accounts of modeling have focused on the modal dimension of scientific inquiry. More precisely, it has been suggested that there are specific models and modeling practices that are best understood as being geared towards possibilities, a view recently dubbed modal modeling. But modalities encompass much more than mere possibility claims. Besides possibilities, modal modeling can also be used to investigate contingencies, necessities or impossibilities. Although these modal concepts are logically connected to the notion of (...) possibility, not all models are equal in their affordances for these richer modal inferences. This paper investigates the modal extent of selected models and argues that analyzing singular model-target pairings by themselves is typically not enough to explain their modal aptness or to identify the kinds of modalities they can be used to reason about. Furthermore, it is argued that some important concepts that are not explicitly modal - like biological robustness - can be understood modally through their relational nature to a background space of possibilities. In conclusion, it is suggested that the strategy of modal modeling is contrastive, situating particular possibilities in larger modal spaces and studying the structural relations within them.

Crosslinguistically, the same modal words can be used to express a wide range of interpretations. This crosslinguistic trend supports a Kratzerian analysis, where each modal has a core lexical entry and where the difference between an epistemic and a root interpretation is contextually determined. A long-standing problem for such a unified account is the equally robust crosslinguistic correlation between a modal’s interpretation and its syntactic behavior: epistemics scope high (in particular higher than tense and aspect) and roots (...) low, a fact which has led to proposals that hardwire different syntactic positions for epistemics and roots (cf. Cinque’s hierarchy). This paper argues that the range of interpretations a modal receives is even more restricted: a modal must be keyed to certain time-individual pairs, but not others. I show that this can be captured straightforwardly by minimally modifying the Kratzerian account: modals are relative to an event—rather than a world—of evaluation, which readily provides a time (the event’s running time) and (an) individual(s) (the event’s participants). I propose that this event relativity of modals can in turn explain the correlation between type of interpretation and syntactic position, without stipulation of an interpretation-specific height for modals.

We do a quantitative analysis of modal logic. For example, for each Kripke structure M, we study the least ordinal μ such that for each state of M, the beliefs of up to level μ characterize the agents' beliefs (that is, there is only one way to extend these beliefs to higher levels). As another example, we show the equivalence of three conditions, that on the face of it look quite different, for what it means to say that the (...) agents' beliefs have a countable description, or putting it another way, have a "countable amount of information". The first condition says that the beliefs of the agents are those at a state of a countable Kripke structure. The second condition says that the beliefs of the agents can be described in an infinitary language, where conjunctions of arbitrary countable sets of formulas are allowed. The third condition says that countably many levels of belief are sufficient to capture all of the uncertainty of the agents (along with a technical condition). The fact that all of these conditions are equivalent shows the robustness of the concept of the agents' beliefs having a "countable description". (shrink)

Paraconsistent logics are logics that, in contrast to classical and intuitionistic logic, do not trivialize inconsistent theories. In this paper we take a paraconsistent view on two famous modal logics: B and S5. We use for this a well-known general method for turning modal logics to paraconsistent logics by defining a new negation as $\neg \varphi =_{Def} \sim \Box \varphi$. We show that while that makes both B and S5 members of the well-studied family of paraconsistent C-systems, they (...) differ from most other C-systems in having the important replacement property. We further show that B is a very robust C-system in the sense that almost any axiom which has been considered in the context of C-systems is either already a theorem of B or its addition to B leads to a logic that is no longer paraconsistent. There is exactly one notable exception, and the result of adding this exception to B leads to the other logic studied here, S5. (shrink)

The Principle of Sufficient Reason —the principle that everything has a reason—plays a central role in Leibniz’s philosophical system. It is rather difficult, however, to determine what Leibniz’s attitude towards the modal status of the PSR is. The prevailing view is that Leibniz takes the PSR to be true necessarily. This paper develops a novel interpretation and argues that Leibniz’s PSR is a contingent principle. It also discusses whether a merely contingent PSR can do the metaphysical heavy lifting that (...) Leibniz aims for. The paper shows that, despite appearance to the contrary, this is possible. In a nutshell, the argument is that the only possible PSR violation Leibniz allows for is God’s creation of a suboptimal world; there is no Leibnizian possible world, though, which intrinsically violates the PSR. Despite its contingency, then, Leibniz’s PSR is modally robust enough to serve as a foundational principle of his metaphysics. (shrink)

Classical modal logics, based on the neighborhood semantics of Scott and Montague, provide a generalization of the familiar normal systems based on Kripke semantics. This paper defines AGM revision operators on several first-order monotonic modal correspondents, where each first-order correspondence language is defined by Marc Pauly’s version of the van Benthem characterization theorem for monotone modal logic. A revision problem expressed in a monotone modal system is translated into first-order logic, the revision is performed, and the (...) new belief set is translated back to the original modal system. An example is provided for the logic of Risky Knowledge that uses modal AGM contraction to construct counter-factual evidence sets in order to investigate robustness of a probability assignment given some evidence set. A proof of correctness is given. (shrink)

Many philosophers believe that there is a causal condition on perception, and that this condition is a conceptual truth about perception. A highly influential argument for this claim is based on intuitive responses to Gricean-style thought experiments. Do the folk share the intuitions of philosophers? Roberts et al. (2016) presented participants with two kinds of cases: Blocker cases (similar to Grice’s case involving a mirror and a pillar) and Non-Blocker cases (similar to Grice’s case involving a clock and brain stimulation). (...) They found that a substantial minority agreed that seeing occurs in the Non-Blocker cases, and that in the Blocker cases significantly less agreed that seeing occurs.

The paper investigates the generality and robustness of Roberts et al.’s findings by expanding the sense modalities tested from only vision to audition and olfaction as well. The paper also uses Gricean-style thought experiments as a case study for investigating the “reflection defense” against the negative project in experimental philosophy. Our results replicate and extend Roberts et al.’s study and support their hypothesis that folk intuitions better align with a no blocker condition.

Despite pervasive variation in the content of laws, legal theorists and anthropologists have argued that laws share certain abstract features and even speculated that law may be a human universal. In the present report, we evaluate this thesis through an experiment administered in 11 different countries. Are there cross‐cultural principles of law? In a between‐subjects design, participants (N = 3,054) were asked whether there could be laws that violate certain procedural principles (e.g., laws applied retrospectively or unintelligible laws), and also (...) whether there are any such laws. Confirming our preregistered prediction, people reported that such laws cannot exist, but also (paradoxically) that there are such laws. These results document cross‐culturally and –linguistically robust beliefs about the concept of law which defy people's grasp of how legal systems function in practice. (shrink)

Ryan Mullins argues that, assuming Hassidic Idealism, God is forced to create all possible worlds (either as a single all-inclusive multiverse, or as an exhaustive array of discrete possible worlds, no one of which is more inherently actual than the other). This process, because unfree, doesn’t amount to creation so much as emanation. I argue that there are numerous ways to reconcile Hassidic Idealism with a robust doctrine of a free Divine creation ex nihilo. We must distinguish between a God (...) who thinks a world into being, and One who, as in the book of Genesis, speaks it into being. (shrink)

Why is it that whenever a structural property is instantiated, its constituent properties are instantiated as well, by proper parts of the original object? By developing a suggestion from Lewis :25–46, 1986), Hawley :117–133, 2010) rises to this explanatory challenge by taking structural properties to be mereologically composed by their constituents, and by taking composition to be analogous to identity. However, setting up a plausible framework for composition and CAI claims about properties, I will argue that structural properties are not (...) identical to their constituents, at least not in any sense robust enough to warrant an Hawley-style argument—and perhaps not identical to them in any sense whatsoever. More generally, core principles of extensional mereology are in danger when applied to structural properties, which may force an extensionalist to either reconsider the application altogether, or reconsider mereological monism, thus granting the mereology of structural properties a peculiarly non-extensional status. Finally, although this debate has been traditionally framed as a debate about universals, an appeal to structural tropes can reconcile, at least to some extent, the mereology of structural properties with Lewisian extensional mereology— CAI included.

Formal methods for representing the characteristic features of organic development and growth make it possible to map the large-scale teleological structure of organic activity. This provides a basis for semantically evaluating, or providing a theory of meaning for, talk of organic activity as purposive. For the processes of organic generation and growth are subjunctively robust under a variety of influences characteristic for the kind or species in question, and these subjunctive conditions can be displayed in a two-dimensional array. After motivating (...) and introducing this array, I use its two dimensions to partially account for features of the purposiveness characterizing two sets of exemplars of the plant and animal kingdoms: ferns and cacti, and cheetah and gazelle. The result is a formal framework for interpreting talk of organic activity as purposive, able to be adapted to a range of research traditions in the philosophy of language and the philosophy of biology.

This article sits at a point of intersection between the philosophy of physics and the metaphysics of modality. There are clear similarities between Everettian quantum mechanics and various modal metaphysical theories, but there have hitherto been few attempts at exploring how the two topics relate. In this article, I build on a series of recent papers by Wilson ([2011], [2012], [2013]), who argues that Everettian quantum mechanics’ connections with traditional modal metaphysics are vital in defending it against objections. (...) I show that Wilson’s preferred version of Everettian quantum mechanics has two problems. First, it is unable to account for the contingency of various intuitively contingent modal claims. Second, it fails to yield intuitive truth values on modal claims about the number of branches in a given Everettian multiverse. Since modal claims about branch number are instrumental in decision-theoretic solutions to Everettian quantum mechanics’ problem(s) with probability, this second problem has wider dialectical implications. I suggest amendments to the underlying metaphysics that overcome these problems. The result is a more robust version of Everettian quantum mechanics. (shrink)

In the past generation, various philosophers have been concerned with the so-called “placement problem” for naturalism. The problem has taken on the shorthand alliteration of the 4Ms, since Mind/Mentality, Meaning, Morality, and Modality/Mathematics are four important phenomena that are difficult to place within orthodox construals of naturalism, typified by physicalism and a methodological preference for ways of knowing associated with the natural sciences. In this paper I highlight the importance of temporality to this ostensibly forced choice between naturalism and the (...) 4Ms, and then reframe the problem by advocating a temporal naturalism rather than the atemporal versions that remain the orthodoxy. In short, I argue in Section 1 that scientific naturalism is standardly atemporal in outlook and in philosophical presuppositions, in Section 2 that temporality is a fundamental condition for each of the 4Ms (drawing on insights from classical phenomenology), and hence the intransigence of the dilemma. Instead of accepting this construal, in Section 3 I outline a temporal naturalism that owes more to biology than to physics (and hence more to Peter Godfrey-Smith than Huw Price), where we also see temporally dependent “points of view” in incipient biological forms, and where the norms surrounding explanation are less nomological and reductive in orientation.

Hands are commonly held up as an exemplar of well-known, familiar objects. However, conceptual knowledge of the hand has been found to show highly stereotyped distortions. Specifically, people judge their knuckles as farther forward in the hand than they actually are. The cause of this distal bias remains unclear. In Experiment 1, we tested whether both visual and tactile information contribute to the distortion. Participants judged the location of their knuckles by pointing to the location on their palm directly opposite (...) each knuckle with: 1) a metal baton (using vision and touch) 2) a metal baton while blindfolded (using touch), 3) a laser pointer (using vision). In Experiment 2, we investigated whether judgments are influenced by visual landmarks such as the creases at the base of each finger on the palm. Participants localized their knuckles on either a photograph or a silhouette of their hand. In both experiments, clear distortions were found across conditions, of generally similar magnitude. These results show that distal bias is resistant to changes in the stimulus information and does not rely on any specific stimulus cue or single sensory modality, suggesting that such mislocalisations reflect a conceptual misrepresentation of hand structure.

Joint attention is typically conceptualized as a robust psychological phenomenon. In philosophy, this apparently innocuous assumption leads to the problem of accounting for the “openness” of joint attention. In psychology, it leads to the problem of justifying alternative operationalizations of joint attention, since there does not seem to be much which is psychologically uniform across different joint attentional engagements. Contrary to the received wisdom, I argue that joint attention is a social relationship which normatively regulates the attentional states of two (...) or more individuals. This social account of joint attention leans on Bart Geurts’ view of communication as commitment sharing. Its promises are: (i) to explain the role of joint attention in wider joint activities, including communicative interactions; (ii) to account for how playing this role requires individuals to deploy different psychological resources on different occasions; and (iii) to identify the rationale behind alternative operationalizations of joint attention.

The purpose of this study is to propose new similarity measures namely rough variational coefficient similarity measure under the rough neutrosophic environment. The weighted rough variational coefficient similarity measure has been also defined. The weighted rough variational coefficient similarity measures between the rough ideal alternative and each alternative are xxxxx calculated to find the best alternative. The ranking order of all the alternatives can be determined by using the numerical values of similarity measures. Finally, an illustrative example has been provided (...) to show the effectiveness and validity of the proposed approach. Comparisons of decision results of existing rough similarity measures have been provided. (shrink)

This paper is devoted to present Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method for multi-attribute group decision making under rough neutrosophic environment. The concept of rough neutrosophic set is a powerful mathematical tool to deal with uncertainty, indeterminacy and inconsistency. In this paper, a new approach for multi-attribute group decision making problems is proposed by extending the TOPSIS method under rough neutrosophic environment. Rough neutrosophic set is characterized by the upper and lower approximation operators and the (...) pair of neutrosophic sets that are characterized by truth-membership degree, indeterminacy membership degree, and falsity membership degree. In the decision situation, ratings of alternatives with respect to each attribute are characterized by rough neutrosophic sets that reflect the decision makers’ opinion. Rough neutrosophic weighted averaging operator has been used to aggregate the individual decision maker’s opinion into group opinion for rating the importance of attributes and alternatives. Finally, a numerical example has been provided to demonstrate the applicability and effectiveness of the proposed approach. (shrink)

Foucault’s theory of power and subjectification challenges common concepts of freedom in social philosophy and expands them through the concept of ‘freedom as critique’: Freedom can be defined as the capability to critically reflect upon one’s own subjectification, and the conditions of possibility for this critical capacity lie in political and social institutions. The article develops this concept through a critical discussion of the standard response by Foucault interpreters to the standard objection that Foucault’s thinking obscures freedom. The standard response (...) interprets Foucault’s later works, especially The Subject and Power, as a solution to the problem of freedom. It is mistaken, because it conflates different concepts of freedom that are present in Foucault’s work. By differentiating these concepts, this article proposes a new institutionalist approach to solve the problem of freedom that breaks with the partly anarchist underpinnings of Foucault scholarship: As freedom as critique is not given, but itself a result of subjectification, it entails a demand for ‘modal robustness’ and must therefore be institutionalized. This approach helps to draw out the consequences of Foucault’s thinking on freedom for postfoundationalist democratic theory and the general social-philosophical discussion about freedom. (shrink)
