This chapter surveys hybrid theories of well-being. It also discusses some criticisms, and suggests some new directions that philosophical discussion of hybrid theories might take.

ABSTRACT When does a state of affairs constitute a harm to someone? Comparative accounts say that being worse off constitutes harm. The temporal version of the comparative account is seldom taken seriously, due to apparently fatal counterexamples. I defend the temporal version against these counterexamples, and show that it is in fact more plausible than the prominent counterfactual version of the account. Non-comparative accounts say that being badly off constitutes harm. However, neither the temporal comparative account nor the non-comparative account (...) can correctly classify all harms. I argue that we should combine them into a hybrid account of harm. The hybrid account is extensionally adequate and presents a unified view on the nature of harm. (shrink)

This essay characterizes the perception of the visual hybrid as nonconceptual, introducing the terminology of nonconceptual content theory to aesthetics. The visual hybrid possesses a radical but nonetheless exemplary aesthetic composition and is well established in culture, art, and even design. The essay supplies a philosophical analysis of the results of cross-cultural experiments, showing that while categorization or conceptual hierarchization kicks in when the visual hybrids are juxtaposed with linguistic descriptions, no conceptual scheme takes effect when participants are presented with (...) mere visual hybrids. In isolation, the hybrids do not lend themselves to classification. I draw four conclusions from these experimental outcomes: 1. The perception of visual hybrids follows the structure of a nonconceptual mental content, because the original categories or concepts of the hybrids’ components are not combined into one, and their properties are not applied to one another, therefore none of the components reconstructs the other such that it is introduced to a new category. 2. Language freezes the hybridity of the visual hybrid into conceptuality. 3. Given that language has a freezing effect in the case of an extreme visual phenomenon such as the hybrid, it is all the more restraining in moderate artistic compositions, such as visual metaphors, in which properties of one component (the source) are applied to the other (the target). In those, nonconceptuality emerges from relatively organized compositions, forms, and relations, and from the dependence of objects and their properties on perceptual context. 4. Thus, the nonconceptualist terminology is suitable for the analysis of aesthetic perception in general and aesthetic perception’s relation to language. Keywords aesthetics, perception, nonconceptual content, hybrids, visual metaphors. (shrink)

Hybrid languages have both modal and first-order characteristics: a Kripke semantics, and explicit variable binding apparatus. This paper motivates the development of hybrid languages, sketches their history, and examines the expressive power of three hybrid binders. We show that all three binders give rise to languages strictly weaker than the corresponding first-order language, that full first-order expressivity can be gained by adding the universal modality, and that all three binders can force the existence of infinite models and have undecidable satisfiability (...) problems.

In this article we define a logical system called Hybrid Partial Type Theory ( $\mathcal {HPTT}$ ). The system is obtained by combining William Farmer’s partial type theory with a strong form of hybrid logic. William Farmer’s system is a version of Church’s theory of types which allows terms to be non-denoting; hybrid logic is a version of modal logic in which it is possible to name worlds and evaluate expressions with respect to particular worlds. We motivate this combination of (...) ideas in the introduction, and devote the rest of the article to defining, axiomatising, and proving a completeness result for $\mathcal {HPTT}$. (shrink)

This paper proposes a novel account of the contents of memory. By drawing on insights from the philosophy of perception, I propose a hybrid account of the contents of memory designed to preserve important aspects of representationalist and relationalist views. The hybrid view I propose also contributes to two ongoing debates in philosophy of memory. First, I argue that, in opposition to eternalist views, the hybrid view offers a less metaphysically-charged solution to the co-temporality problem. Second, I show how the (...) hybrid view conceives of the relationship between episodic memory and other forms of episodic thinking. I conclude by considering some disanalogies between perception and memory and by replying to objections. I argue that, despite there being important differences between memory and perception, those differences do not harm my project. (shrink)

The transgressive ontological character of hybrids—entities crossing the ontological binarism of naturalness and artificiality, e.g., biomimetic projects—calls for pondering the question of their ethical status, since metaphysical and moral ideas are often inextricably linked. The example of it is the concept of “moral considerability” and related to it the idea of “intrinsic value” understood as a non-instrumentality of a being. Such an approach excludes hybrids from moral considerations due to their instrumental character. In the paper, we revisit the boundaries of (...) moral considerability by reexamining the legitimacy of identifying intrinsic value with a non-instrumental one. We offer the concept of “functional value,” which we define as a simultaneous contribution to the common good of the ecosystem and the possibility to disclose the full variety of aspects of a being’s identity. We argue that such a value of hybrids allows us to include them into the scope of moral considerability. (shrink)

Hybrid logics are a principled generalization of both modal logics and description logics, a standard formalism for knowledge representation. In this paper we give the first constructive version of hybrid logic, thereby showing that it is possible to hybridize constructive modal logics. Alternative systems are discussed, but we fix on a reasonable and well-motivated version of intuitionistic hybrid logic and prove essential proof-theoretical results for a natural deduction formulation of it. Our natural deduction system is also extended with additional inference (...) rules corresponding to conditions on the accessibility relations expressed by so-called geometric theories. Thus, we give natural deduction systems in a uniform way for a wide class of constructive hybrid logics. This shows that constructive hybrid logics are a viable enterprise and opens up the way for future applications. (shrink)

The recent resurgence of extreme-right movements and the nationalist turn of many governments across the world have reignited the relevance of discussions within educational philosophy about the teaching of national identity in schools. However, the conceptualisation of national identity in previous iterations of these debates have been largely Western and Eurocentric, making the past theoretical literature about these questions less relevant for post-colonial settings. In this paper, I imagine a new approach for teaching national identity in post-colonial contexts, founded on (...) postcolonial conceptions of identity and in particular, the concept of hybridity. I first develop a postcolonial account of national identity by drawing on Homi Bhabha’s thinking about cultural identity, drawing on his concepts of liminality, splitting, and ambivalence. Then, building on Bhabha's notion of hybridity, I propose a distinction between national identity portrayals as either fixed or malleable. Finally, I demonstrate the implications of such a conceptual distinction on the way that national identity is taught in post-colonial schools; by way of an example, I envision a concrete approach to teaching national identity that views national identity as malleable rather than fixed, set in a hypothetical postcolonial school in the Philippines. By beginning from postcolonial assumptions about national identity, I hope to indicate new directions that the debates about the teaching of national identity in schools might proceed. (shrink)

This is a draft of a chapter for the Routledge Handbook of Metaethics, edited by David Plunkett and Tristram McPherson. I offer an overview of hybrid views in metaethics, with main focus on hybrid cognitivist views such as those defended by Daniel Boisvert and David Copp, and on hybrid expressivist views such as those defended by Michael Ridge and myself.

This article focuses on Latin American constitutionalism with two goals in mind. The first goal is to identify narratives of constitutional mixity or hybridity that have been influential in Latin America, something that habilitates a comparative analysis with references to mixed or hybrid constitutionalism in other scenarios. One narrative underlines the combination of U.S.-inspired constitutionalism with background civil law systems. Another narrative highlights the way classic regional constitutional designs feature a liberal-conservative hybridation that, some claim, continue to influence constitutional (...) dynamics up to this day. And the third narrative is associated with the establishment in regional countries of hybrid or mixed systems of judicial review. The second goal of the article, more methodological in kind, is to explore what do Latin American narratives on mixity teach in the way to clarifying the nature and implications of exercises constitutional taxonomy. As it emerges, constitutional taxonomy is a way of organizing and generating knowledge which is useful to describe, but most meaningful when addressed to provide an explanation, which is often just an antechamber to normative evaluation. Whether a particular exercise of constitutional taxonomy makes sense in a particular scenario, however, is a different matter, and the article suggests that describing, explaining and evaluating Latin American constitutions as hybrid is illuminating but also problematic in a number of ways.

This paper is a survey of recent ‘hybrid’ approaches to metaethics, according to which moral sentences, in some sense or other, express both beliefs and desires. I try to show what kinds of theoretical issues come up at the different choice points we encounter in developing such a view, to raise some problems and explain where they come from, and to begin to get a sense for what the payoff of such views can be, and what they will need to (...) do in order to earn that payoff.

Grasping the identity of hybrids, that is beings which cross the binarism of nature and technology (e.g. genetically-modified organisms (GMOs), syn-bio inventions, biomimetic projects), is problematic since it is still guided by self-evident dualistic categories, either as artefacts or as natural entities. To move beyond the limitations of such a one-sided understanding of hybrids, we suggest turning towards the categories of affordances and the juxtaposition of needs and patterns of proper use, as inspired by the Heideggerian version of phenomenology. Drawing (...) upon selected concepts by Heidegger, we argue that hybrids can be conceptualised as a regenerative design and use to serve the planet. We argue that the ideal type of non-exploitative account of hybrids consists of the adaptive approach to the environment, which does not, however, exclude the possibility of designing and constructing new beings. We also point out that hybrids undermine the divide of being destructive/regenerative which marks the boundaries of nature and technology. (shrink)

This is an extended version of the lectures given during the 12-thConference on Applications of Logic in Philosophy and in the Foundationsof Mathematics in Szklarska Poręba. It contains a surveyof modal hybrid logic, one of the branches of contemporary modal logic. Inthe first part a variety of hybrid languages and logics is presented with adiscussion of expressivity matters. The second part is devoted to thoroughexposition of proof methods for hybrid logics. The main point is to showthat application of hybrid logics (...) may remarkably improve the situation inmodal proof theory. (shrink)

Sometimes logical support for a conclusion is provided exclusively by premises which are independently relevant to that conclusion. At other times, support is provided exclusively by independently irrelevant premises. On still other occasions, relevant and irrelevant premises may collectively offer a distinctive pattern of support. This paper provides a rigorous account of some of these differences in terms of a tripartite classification of convergent, linked and hybrid arguments. These various arguments are defined, diagrammed, and some of their logical properties are (...) explored. (shrink)

A hybrid theory is any moral theory according to which different classes of individuals ought to be treated according to different principles. We argue that some hybrid theories are able to meet standards of psychological plausibility, by which we mean that it’s feasible for ordinary human beings to understand and act in accord with them. Insofar as psychological plausibility is a theoretical virtue, then, such hybrid theories deserve more serious consideration. To make the case for this view, we explain what (...) psychological plausibility is and why we might value it, why the human/animal divide appears to be an entrenched feature of human psychology, and why Robert Nozick’s hybrid theory doesn’t go far enough. Finally, we make the case that a more promising psychologically plausible hybrid theory, with respect to humans and animals, will be (at least) at tribrid theory—that is, positing three domains rather than two.

In this text an overview is offered of some of the most significant categories of the demonic from the Mesopotamian beliefs – of hybridity and liminality – through some examples of the conceptions of the demons Pazuzu and Lamaštu. Firstly, the logicaldialectical relations of the sphere of the demonic as external and foreign, opposed to the homely, familiar and close sphere are sketched; as well as the relation of the demonic as terrifying and potentially menacing, as opposed to the ordered (...) civilized sphere with norms of conduct. Then, several representations of the concepts of Pazuzu as an ambivalent demon are listed – he is an evil fighting against evil, his nemesis, Lamaštu, and precisely because of the need for him to be efficient in his protective function, he has to be a horrifying, dangerous demon. This is shown through the descriptions of the available incantations and preserved rituals. The terrifying threat of Lamaštu against the most precious part of the communities – the new generations - through her snatching and destroying of the newborns, is shown through the representations of her hybridity and monstrosity, and mainly through the incantations for her removal and (permanent) expulsion.

The Anthropocene overthrows classical dichotomies like technology and nature and a new class of beings emerges: hybrids. The transitive status of hybrids - which establishes an extra, separate, 'third' ontological category, going beyond the dichotomy between nature and technology - constitutes a significant problem for environmental philosophy and philosophy of technology since they traditionally focus on either 'nature' (natural entities) or 'artefacts' (technological objects). In order to reflect on the ethical significance of hybrids, a classification of different types of hybrids (...) is required. Such a classification is provided by this article, based on insights from both environmental philosophy and philosophy of technology. After explaining why a new class of beings emerges in the Anthropocene, and reflecting on the one-sidedness of philosophy of technology and environmental philosophy in their focus on either technology or nature, we propose a new classification of hybrids in this article that provides a new starting point for reflections on the moral significance of hybrids in environmental philosophy and philosophy of technology.

Hybrid identities are sentences in a special second order language with identity. The model classes of sets of hybrid identities are called hybrid solid varieties. We give a Birkhoff-type-characterization of hybrid solid varieties and develop a hybrid equational logic.

The theory of collective agency and intentionality is a flourishing field of research, and our understanding of these phenomena has arguably increased greatly in recent years. Extant theories, however, are still ill-equipped to explain certain aspects of collective intentionality. In this article we draw attention to two such underappreciated aspects: the failure of the intentional states of collectives to supervene on the intentional states of their members, and the role of non-human factors in collective agency and intentionality. We propose a (...) theory of collective intentionality which builds on the ‘interpretationist’ tradition in metasemantics and the philosophy of mind as initiated by David Lewis and recently developed further by Robbie Williams. The collective-level analogue of interpretationism turns out to look different in some ways from the individual-level theory, but is well-suited to accommodating phenomena such as hybrid collective intentionality. Complemented with Kit Fine’s theory of variable embodiment, such a theory also provides a diachronic account of intentional collectives. (shrink)

This article examines G. A. Cohen’s endorsement of a hybrid ethical theory and its relationship to his critique of John Rawls’s egalitarian liberalism. Cohen claimed that Rawls’s appeal to special incentives was a distortion of his own difference principle. I argue that Cohen’s acceptance of a personal prerogative (the central element of Samuel Scheffler’s version of a hybrid ethical theory) has several untoward consequences. First, it illuminates how any reasonable challenge to Rawls’s liberalism must recognise Thomas Nagel’s arguments concerning the (...) problems that arise when one attempts to implement a political theory analogous to a hybrid theory of ethics. Second, it undermines Cohen’s critique of Rawls. Third, it undermines the plausibility of Cohen’s ethos-driven social egalitarianism. The article concludes that, despite Nagel’s concerns, the most plausible form of egalitarianism—one that can accommodate the requirements of a hybrid ethical theory—will be Rawlsian, rather than Cohen’s ethos-based system.

This is the first book-length treatment of hybrid logic and its proof-theory. Hybrid logic is an extension of ordinary modal logic which allows explicit reference to individual points in a model. This is useful for many applications, for example when reasoning about time one often wants to formulate a series of statements about what happens at specific times. There is little consensus about proof-theory for ordinary modal logic. Many modal-logical proof systems lack important properties and the relationships between proof systems (...) for different modal logics are often unclear. In the present book we demonstrate that hybrid-logical proof-theory remedies these deficiencies by giving a spectrum of well-behaved proof systems for a spectrum of different hybrid logics. (shrink)

This paper points out a tension between Agustín Rayo's criteria for singulartermhood and his explicit views on the status of Hybrid Identities, that is, identity statements that use singular terms from two different Systems of Representation, such as "7=Julius Caesar" or more suggestively "I am b" where "b" is a singular term referring to my brain. It argues that non-trivial Hybrid Identities are common and important in philosophy and elsewhere, and it suggests a friendly alternative that involves treating Hybrid Identities (...) on the model of Rayo's "Just Is" statements. The last section of the paper points out that even this friendly alternative has counterintuitive consequences when combined with the metaphysical conventionalism that Rayo finds attractive, when it comes to questions of personal identity over time.

With the increasing degrees A.I.s and machines are applied across different social contexts, the need for implementing ethics in A.I.s is pressing. In this paper, we argue for a pluralist hybrid model for the implementation of moral A.I.s. We first survey current approaches to moral A.I.s and their inherent limitations. Then we propose the pluralist hybrid approach and show how these limitations of moral A.I.s can be partly alleviated by the pluralist hybrid approach. The core ethical decision-making capacity of an (...) A.I. based on the pluralist hybrid approach consists of two systems. The first is a deterministic algorithm system that incorporates different moral rules for making explicit moral decisions. The second is a machine learning system that calculates the value of the variables required by the application of moral principles. The pluralist hybrid system is better than the existing proposals as (i) it better addresses the moral disagreement problem of the top-down approach by including different moral principles, while (ii) it reduces the opacity of ethical decision-making compared with a bottom-up system by implementing explicit moral principles for moral decision making.

Water quality prediction is the basis of water environmental planning, evaluation, and management. In this work, a novel intelligent prediction model based on the fuzzy wavelet neural network including the neural network, the fuzzy logic, the wavelet transform, and the genetic algorithm was proposed to simulate the nonlinearity of water quality parameters and water quality predictions. A self-adapted fuzzy c-means clustering was used to determine the number of fuzzy rules. A hybrid learning algorithm based on a genetic algorithm and gradient (...) descent algorithm was employed to optimize the network parameters. Comparisons were made between the proposed FWNN model and the fuzzy neural network, the wavelet neural network, and the neural network. The results indicate that the FWNN made effective use of the self-adaptability of NN, the uncertainty capacity of FL, and the partial analysis ability of WT, so it could handle the fluctuation and the nonseasonal time series data of water quality, while exhibiting higher estimation accuracy and better robustness and achieving better performances for predicting water quality with high determination coefficients R2 over 0.90. The FWNN is feasible and reliable for simulating and predicting water quality in river. (shrink)

We characterize the modal logics of elementary classes of Kripke frames as precisely those modal logics that are axiomatized by modal axioms synthesized in a certain effective way from "quasi-positive" sentences of hybrid logic. These are pure positive hybrid sentences with arbitrary existential and relativized universal quantification over nominals. The proof has three steps. The first step is to use the known result that the modal logic of any elementary class of Kripke frames is also the modal logic of the (...) closure of this class under disjoint unions, generated subframes, bounded morphic images, and ultraroots. This latter class can be defined by the first-order sentences of a special syntactic form (called pseudo-equations by Goldblatt) that are valid in the former class. The second step is to translate these pseudo-equations into equivalent quasi-positive hybrid sentences. In the third and main step, we show that any quasi-positive sentence S generates an infinite set of modal formulas called "approximants," which together axiomatize a canonical modal logic that is sound and complete for the class of frames validating S. The proof is analogous to standard proofs of Sahlqvist's theorem. It generalizes to sets of quasi-positive sentences. The main result now follows. (shrink)

Sufism has two main dimensions: vertical (God's pleasure) and horizontal (harmony with nature, society and local wisdom). In reality, many Sufis are considered less concerned about the balancing between vertical and horizontal dimensions. The research explores the concepts and practices of hybrid Sufism undertaken by Kyais (religious leaders) and their followers in improving quality of life. Ethnography was used for exploring the mindset and activities of Kyai and his followers. This study involved four Kyais in Java and Kalimantan, Indonesia. Research (...) data were obtained through participant observations, in-depth interviews and documentation. The data were analysed by Spadley's ethnographic steps as follows: (1) domain analysis, (2) taxonomy analysis, (3) componential analysis and (4) cultural-thematic analysis. The results showed that hybrid Sufism could improve quality of life. Hybrid Sufism can better appreciate and interpret local wisdom with an attitude of preserving nature and a positive understanding of worldly wealth, increasing the hard work ethos to achieve material-spiritual qualities. CONTRIBUTION: This article shows that hybrid Sufism encourages the life of Sufis in harmony between vertical and horizontal aspects. This understanding and lifestyle give rise to respect for others, being friendly to the environment and interpreting life and local wisdom. (shrink)

Psychologists of concepts’ traditional assumption that there are many properties common to all concepts has been subject to devastating critiques in psychology and in the philosophy of psychology. However, it is currently unclear what approach to concepts is best suited to replace this traditional assumption. In this article, we compare two competing approaches, the Heterogeneity Hypothesis and the hybrid theories of concepts, and we present an empirical argument that tentatively supports the former over the latter.

According to an influential account of the new mechanistic philosophy of science, entities and activities compose mechanisms. However, the new mechanists have paid too little attention to activities. Critics have charged that accounts of activities in the new mechanism literature are philosophically uninformative and opaque. This paper defends a novel account of causally productive activities, which I call the Hybrid Account, that marries the two dominant philosophical approaches to causation: production and difference-making. The Hybrid Account of Activities (HAA) identifies causally (...) productive activities as robust difference-makers to the next stage of a mechanism. The Hybrid Account provides attractive solutions to causal identification and causal selection problems faced by earlier activities views. (shrink)

We study hybrid logics in topological semantics. We prove that hybrid logics of separation axioms are complete with respect to certain classes of finite topological models. This characterisation allows us to obtain several further results. We prove that aforementioned logics are decidable and PSPACE-complete, the logics of T 1 and T 2 coincide, the logic of T 1 is complete with respect to two concrete structures: the Cantor space and the rational numbers.

In the field of cybernetic systems and more specifically in robotics, one of the fundamental objectives is the detection of anomalies in order to minimize loss of time. Following this idea, this paper proposes the implementation of a Hybrid Intelligent System in four steps to impute the missing values, by combining clustering and regression techniques, followed by balancing and classification tasks. This system applies regression models to each one of the clusters built on the instances of data set. Subsequently, a (...) variety of balancing techniques are applied to improve the classifier’s ability to discern whether it is in an error or a normal state. These techniques support to obtain better classification ratios in which a robot is close to error and allow us to bring the behavior back to a normal state. The experimentation is performed using a modern and public data set, which has been extracted from a component-based robotic system, in which different anomalies are induced by software in their components.

Sentences containing predicates of personal taste (for example, ‘tasty’, ‘funny’) and aesthetic predicates (for example, ‘beautiful’) give rise to an acquaintance inference: They convey the information that speakers have first-hand experience with the object of predication and they can only be uttered appropriately if that is the case. This is surprisingly hard to explain. I will concentrate on aesthetic predicates, and firstly criticize previous attempts to explain the acquaintance phenomena. Second, I will suggest an explanation that rests on a speech (...) act theoretical version of hybrid expressivism, according to which, in uttering ‘X is beautiful’ speakers perform two illocutionary acts simultaneously: an expressive and an assertive one. I will spell out this suggestion in detail and defend it against objections. Considering puzzles related to the acquaintance inference will lead to a new argument for a promising version of hybrid expressivism in meta-aesthetics. (shrink)

By beginning from postcolonial assumptions about national identity, I hope to indicate new directions that the debates about the teaching of national identity in schools might proceed. (shrink)

The ‘European Green Deal’ (EGD) is a set of communications from the European Commission that outlines EU roadmap to climate neutrality by 2050. The policy envisions that, with the facilitation of speedy and just ‘green transition’, the goals of environmental protection and economic development can be reconciled. This article offers a language-focused critical study of the EGD. After giving an overview of neoliberal ‘discourses of sustainability’ and explaining the notion of ‘interdiscursivity’ in CDS, it presents the results of a close (...) thematic analysis supported by keyword and concordance analysis of representations of ‘environment’ and ‘climate’ on the one hand, and ‘economy’ and ‘transition’ on the other. This study attends to salient language patterns and reveals how interdiscursive crossovers are established to normalise ‘sustainability’ as the contingency between environmental and economic orders of discourse. Also, it identifies the discursive strategies of nomination, predication, argumentation, perspectivisation and mitigation or intensification and shows how tensions between discourses are smoothened. This analysis of EGD’s ideological hybridity also sheds light onto how EU institutions are (self)authorised to lead actions on environmental challenges on behalf of European citizens. (shrink)

In virtue of what is something a reason for action? That is, what makes a consideration a reason to act? This is a metaphysical or meta-normative question about the grounding of reasons for action. The answer to the grounding question has been traditionally given in ‘pure’, univocal terms. This paper argues that there is good reason to understand the ground of practical normativity as a hybrid of traditional ‘pure’ views. The paper 1) surveys the three leading ‘pure’ answers to the (...) question of a normative ground, 2) examines one or two of the most difficult problems for each, proposing along the way a new objection to one, and 3) argues that a particular hybrid view about normative grounds –‘hybrid voluntarism’ – avoids each of the main problems faced by the three leading ‘pure’ views.

Hybrid languages are expansions of propositional modal languages which can refer to worlds. The use of strong hybrid languages dates back to at least [Pri67], but recent work has focussed on a more constrained system called $\mathscr{H}$. We show in detail that $\mathscr{H}$ is modally natural. We begin by studying its expressivity, and provide model theoretic characterizations and a syntactic characterization. The key result to emerge is that $\mathscr{H}$ corresponds to the fragment of first-order logic which is invariant for generated (...) submodels. We then show that $\mathscr{H}$ enjoys interpolation, provide counterexamples for its finite variable fragments, and show that weak interpolation holds for the sublanguage $\mathscr{H}$. Finally, we provide complexity results for $\mathscr{H}$ and other fragments and variants, and sharpen known undecidability results for $\mathscr{H}$. (shrink)

Hybrid contingentism combines first-order contingentism, the view that it is contingent what individuals there are, with higher-order necessitism, the view that it is non-contingent what properties and propositions there are (where these are conceived as entities in the range of appropriate higher-order quantifiers). This combination of views avoids the most delicate problems afflicting alternative contingentist positions while preserving the central contingentist claim that ordinary, concrete entities exist contingently. Despite these attractive features, hybrid contingentism is usually faced with rejection. The main (...) reason for this is an objection that crucially involves haecceitistic properties, properties such as being identical to Plato or being identical to Aristotle. The objection alleges that by accepting the necessary existence of such haecceities, hybrid contingentists incur an explanatory commitment that they are unable to discharge, namely that of explaining how it is that certain haecceities ‘lock onto’ their target individuals even when those individuals are absent. To defend hybrid contingentism against this charge, I first clarify the haecceities objection in several respects and consider, in particular, what notion of explanation the objection is operating with. After arguing that it can be fruitfully understood as a challenge to provide metaphysical grounds for certain haecceity facts, I develop a contingentist response to the objection that draws on recent work on the connection between ground and essence.

The hybrid logic and the independence friendly modal logic IFML are compared for their expressive powers. We introduce a logic IFML c having a non-standard syntax and a compositional semantics; in terms of this logic a syntactic fragment of IFML is singled out, denoted IFML c . (In the Appendix it is shown that the game-theoretic semantics of IFML c coincides with the compositional semantics of IFML c .) The hybrid logic is proven to be strictly more expressive than IFML (...) c . By contrast, and the full IFML are shown to be incomparable for their expressive powers. Building on earlier research (Tulenheimo and Sevenster 2006), a PSPACE -decidable fragment of the undecidable logic is disclosed. This fragment is not translatable into the hybrid logic and has not been studied previously in connection with hybrid logics. In the Appendix IFML c is shown to lack the property of ‘quasi-positionality’ but proven to enjoy the weaker property of ‘ bounded quasi-positionality’. The latter fact provides from the IFML internal perspective an account of what makes the compositional semantics of IFML c possible. (shrink)
