What are the consequences of modernity for the institution of contracting? As the unity of the traditional contract is dissolved into a multiplicity of separate contracting worlds, the binding force of contracting needs to be reformulated from an interpersonal to an interdiscursive relation. The central thesis of this Article is that the unity of contracting is hidden in the blind spot of the distinction between contracting worlds. Contracting needs two diametrically contradictory but complementary theories which cannot be integrated into a (...) synthesis. As demonstrated with the example of the expertise contract, the subtle interplay of different contracting worlds depends basically on a fragile symmetry of chances of translation. The normative correlate of contract understood as translation between different worlds of meaning would be an extension of constitutional rights into the context of private governance regimes.

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.

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)

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)

The main aim of the present paper is to use a proof system for hybrid modal logic to formalize what are called false-belief tasks in cognitive psychology, thereby investigating the interplay between cognition and logical reasoning about belief. We consider two different versions of the Smarties task, involving respectively a shift of perspective to another person and to another time. Our formalizations disclose that despite this difference, the two versions of the Smarties task have exactly the same underlying logical structure. (...) We also consider the Sally-Anne task, having a more complicated logical structure, presupposing a “principle of inertia” saying that a belief is preserved over time, unless there is belief to the contrary.

A growing body of nursing writing is engaged in reviewing the material and relational world of nursing using geographical concepts. This paper draws upon research undertaken in hospital settings where nurses constituted the hospital as a home space for patients. Nurses’ practices created an equitable and patient‐centred use of physical space in the hospital ward, along with the intimate, extended and personal relationships associated by patients with a caring and homely environment. It is suggested that this constitution of space resonates (...) with the geographic notion of the therapeutic landscape and can be read as a challenge to more conventional uses of hospital spaces shaped by biomedical concerns. The implications of merging the distinctly different spaces and places of home and hospital are also explored using the concepts of hybridity and spatial vulnerability. The complex hybrid nursing creation of home space within hospital places works against the grain of usual understandings of hospitals as specialised illness spaces that are the domain of the health professional inhabitants. While there are limitations and dangers in the representation, this constitution of space is an expression of core nursing values privileging patient–nurse relationships and supports the maintenance of identity and personal expression.

Disagreement is a pervasive feature of human discourse and a crucial force in shaping our social reality. From mundane squabbles about matters of taste to high-stakes disputes about law and public policy, the way we express and navigate disagreement plays a central role in both our personal and political lives. Legal discourse, in particular, is rife with disagreement - it is the very bread and butter of courtroom argument and legal scholarship alike. Consider a debate between two legal philosophers, Ronald (...) and Herbert, about the Eighth Amendment of the U.S. Constitution, which prohibits ‘cruel and unusual punishment’. Ronald asserts: ‘It is the law that capital punishment is prohibited’. In response, Herbert states: ‘It is not the law that capital punishment is prohibited’. We intuitively think Ronald and Herbert are disagreeing, which reveals in the fact that they are licensed to use ex¬pressions like no (it isn’t) and nuh-uh when responding to their opponent’s claim. But despite the ubiquity and significance of legal disagreement, its precise nature remains elusive. This chapter discusses what exactly is going on when two people disagree about what the law requires, and how can hybrid theory may answer this question. (shrink)

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 takes issue with the way the highly fashionable concept of hybridity has been used to skew our understanding of cultural identity, and render conceptually and normatively indefensible the political claims of culture. It also challenges the current ‘anti-essentialist’ orthodoxy about what culture ‘really is,’ and shows that neither ‘essentialism’ nor ‘anti-essentialism’ helps us get right the place of culture in politics, because both fail to recognize the identity and non-identity of culture with itself.

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.

The purpose of this paper is to argue that the hybrid formalism fits naturally in the context of David Lewis’s counterfactual logic and that its introduction into this framework is desirable. This hybridization enables us to regard the inference “The pig is Mary; Mary is pregnant; therefore the pig is pregnant” as a process of updating local information (which depends on the given situation) by using global information (independent of the situation). Our hybridization also has the following technical (...) advantages: (i) it preserves the completeness and decidability of Lewis’s logic; (ii) it allows us to characterize the Limit Assumption as a proof-rule with some side-conditions; and (iii) it enables us to establish a general Kripke completeness result by using the proof-rule corresponding to the Limit Assumption.

In Hybrid artwork, whereby the digital and the real are mixed, the artist/creator has to additionally manage interaction. Interaction is seen as an added dimension to narration: the art piece turns from being a means towards a narration (or an understanding) to a path towards an experience. It is argued that strong metaphysical concepts give place to new more fragmented ones. This nihilism and fragmentation can be seen as a cause of concern but also as an opportunity.

The case law of the Court of Justice of the European Union is shaped by the language in which it is drafted—i.e. French. However, because French is rarely the mother tongue of those drafting that case law, the texts produced are often stilted and awkward. In addition, those drafting such case law are constrained in their use of language and style of writing. These factors have led to the development of a ‘Court French’ which necessarily shapes the case law produced (...) and has implications for its development, particularly insofar as it inevitably leads to a type of precedent in that case law. That case law also undergoes many permutations of translation into and out of up to 23 different languages. The resultant texts that make up the case law are hybrid in nature—consisting of a blend of cultural and linguistic patterns, constrained by a rigid formulistic drafting style and put through many permutations of translation. The present paper investigates the production of the Court’s multilingual case law and considers whether the hybrid nature of that case law can actually aid the presentation of a ‘uniform’ EU case law.

We show that every extension of the basic hybrid logic with modal Sahlqvist axioms is complete. As a corollary of our approach, we also obtain the Beth property for a large class of hybrid logics. Finally, we show that the new completeness result cannot be combined with the existing general completeness result for pure axioms.

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)

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.

This study contributes to the growing interest in how hybrid organizations manage paradoxical social–business tensions. Our empirical case is “impact sourcing”—hybrids in global supply chains that hire staff from disadvantaged communities to provide services to business clients. We identify two major growth orientations—“community-focused” and “client-focused” growth—their inherent tensions and ways that hybrids manage them. The former favors slow growth and manages tensions through highly integrated client and community relations; the latter promotes faster growth and manages client and community relations separately. (...) Both growth orientations address social–business tensions in particular ways, but also create latent constraints that manifest when entrepreneurial aspirations conflict with the current growth path. In presenting and discussing our findings, we introduce preempting management practices of tensions, and the importance of geographic embeddedness and distance to the paradox literature. (shrink)

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.

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)

Hybride der Romantik: Frankenstein, Olimpia und das künstliche Leben. Dieser Beitrag untersucht Vorstellungen über die Möglichkeit der Erzeugung künstlicher Lebewesen in der Zeit der Romantik und die damit verbundenen Ängste am Beispiel zweier fiktionaler Texte: Mary Shelleys Frankenstein und Ernst Theodor Amadeus Hoffmanns Sandmann. Dr. Franksteins Monster und Dr. Spalanzanis Automat verkörpern – auf unterschiedliche Weise – die Möglichkeit einer Wendung wissenschaftlicher Produkte und insbesondere künstlicher Hybride ins Monströse. Ihre Geschichten thematisieren das Grauen, das vom drohenden Kontrollverlust ausgeht und als (...) der modernen Wissenschaft innewohnende Gefahr selbst nach der Zerstörung der monströsen Kreaturen bestehen bleibt. Der Begriff des Unheimlichen, von Ernst Jentsch und Sigmund Freud mit Bezug auf Hoffmanns Sandmann formuliert und 1970 von dem japanischen Robotiker Masahiro Mori als Phänomen „des unheimlichen Tals“ (Uncanny Valley) weiterentwickelt, erlaubt weitere Einblicke in die Frage nach künstlichen Lebewesen und ihre Interaktion mit Menschen. Summary: Hybrids of the Romantic: Frankenstein, Olimpia, and Artificial Life. This essay analyzes fantasies and fears related to the possible creation of artificial humans in two influential pieces of Romantic literature, namely E.T.A. Hoffmann's Der Sandmann and Mary Shelley's Frankenstein. Both the automaton Olimpia and Dr. Frankenstein's monster are hybrid creatures. These dystopian figures represent the Romantic fear of the loss of control over the outcome of human endeavour, they symbolize the dangers immanent in modern science and technology. As hybrids, Olimpia and Frankenstein's monster are capable of breaking apparently unpenetrable boundaries, such as those between human and non‐human, and between life and death. As such, these creatures become “unheimlich” (uncanny), a critical term developed by Ernst Jentsch and Sigmund Freud, who directly referred to Hoffmann's Sandman. The term “uncanny” was further developed by the Japanese roboticist Masahiro Mori in the 1970s. Mori's investigation of human responses to androids (“Uncanny Valley”), shows the persistence of doubts and fears surrounding artificial humans far beyond the Romantic times, and opens new questions related to the issues of creation, reproduction, hybrids, hubris and gender.

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.

Bex analyzes the case with an informal version of his hybrid theory, which combines scenario construction and argumentation. Arguments based on evidence can be used to reason about alternative scenarios. Bex claims that his hybrid theory provides the best of both worlds by combining cognitively feasible story‐based reasoning with more detailed rational argumentation. However, like the argument‐based approach, the hybrid theory does not provide a systematic account of uncertainty.

Epistemic expressivists maintain, to a first approximation, that epistemic assertions express non-cognitive mental states, like endorsements, valuations, or pro-attitudes, rather than cognitive mental states such as beliefs. Proponents of epistemic expressivism include Chrisman, Gibbard, Field, Kappel, and Ridge, among others. In this paper, I argue for an alternative view to epistemic expressivism. The view I seek to advocate is inspired by hybrid expressivist theories about moral judgments, Copp Oxford studies in metaethics, 2009), Finlay, Strandberg ). According to these hybrid views, (...) moral judgments express semantically cognitive or representational states and pragmatically convey the speaker’s non-cognitive mental states via implicatures. I will argue that a particular version of this view can reasonably be extended to epistemic judgments and that it has several advantages over its expressivist and cognitivist competitors. In particular, I will try to show that there exist certain phenomena in the epistemic domain that seem to be best accounted for by expressivist theories of epistemic judgments. However, a version of hybrid expressivism that maintains that epistemic judgments convey the attributor’s non-cognitive mental states via generalized conversational implicatures is able to account for these phenomena just as well without running afoul of the main problems that have been identified for different versions of epistemic expressivism.

Structural problems are examined with pairing two chambers, one selected by election and the other by sortition, into a traditional bicameral system. It is argued that an all-purpose legislative chamber modeled on existing elected chambers is a mismatch for sortition and that purported benefits of maintaining partisan elections alongside sortition are illusory. Alleged benefits of a hybrid bicameral system are shown to be outweighed by a variety of harmful effects. Furthermore, even if those harms are not substantiated, the continued existence (...) of an elected chamber will likely result in the delimitation of the sortition chamber. Combining many different sorts of minipublics with different characteristics and functions is preferable, and a possible multibody sortition legislative system is presented. Finally, an alternative way forward for sortition is proposed by peeling away individual topic areas from elected bodies and transferring them to sortition bodies. (shrink)

In this paper we show the embedding of Hybrid Probabilistic Logic Programs into the rather general framework of Residuated Logic Programs, where the main results of (definite) logic programming are validly extrapolated, namely the extension of the immediate consequences operator of van Emden and Kowalski. The importance of this result is that for the first time a framework encompassing several quite distinct logic programming semantics is described, namely Generalized Annotated Logic Programs, Fuzzy Logic Programming, Hybrid Probabilistic Logic Programs, and Possibilistic (...) Logic Programming. Moreover, the embedding provides a more general semantical structure paving the way for defining paraconsistent probabilistic reasoning with a logic programming semantics.

How do promissory obligations get created? Some have thought that the answer to this question must make reference to our social practice of promising. Recently, however, T.M. Scanlon has argued (in his book What We Owe to Each Other) for a pure ‘expectation view’ of promising, according to which promissory obligations arise as a result of our producing certain expectations in others. He formulates a principle of fidelity (Principle F) that tells us when one has gained an obligation due to (...) producing expectations in another, and he maintains that breaking one's promise is merely a special instance of violation against Principle F. Though initially compelling, Scanlon’s account is ultimately unsatisfactory because it is subject to a vicious circularity. In order to get out of the circle, we are forced to resort back to elements of a social practice view of promising. Thus we arrive at a hybrid view of promissory obligation, which weds parts of Scanlon’s expectation view with parts of a social practice view. After briefly examining and rejecting Scanlon’s pure expectation view, I consider the hybrid view of Niko Kolodny and R. Jay Wallace. I present a serious objection to the hybrid view as they formulate it and go on to construct a modified hybrid view. Finally, I defend my modified hybrid view from certain pressing objections.

Analysis of the debate concerning the appropriate way of researching the effects of complementary and alternative medicine (CAM) treatments highlights the controversial issue of the mind–body bond in medical research. The article examines a range of approaches, extending from outright opposition to CAM research, through the demand to employ only rigorous trials, to suggestions to use a hierarchy of evidence, up to practice‐based research proposals. These diverse approaches are analysed using theoretical concepts from the field of sociology of science and (...) knowledge. The article uses the concept of “hybrid knowledge” to denote the knowledge being constructed in late modern CAM discourse—knowledge that hybridises differentiated and even contradictory modern categories of knowledge. The article suggests that the different approaches taken by sociologists of science and knowledge, such as strong anti‐dualism and the assertion that there are differences in our understanding of the natural and the cultural–social terrain, are all useful and are not necessarily mutually exclusive. The article seeks to clarify the debate concerning the appropriate way of researching CAM and to contribute to the ongoing development and application of sociology of knowledge. (shrink)

: In recent literature supporting a hybrid view between metaethical cognitivism and noncognitivist expressivism, much has been made of an analogy between moral terms and pejoratives. The analogy is based on the plausible idea that pejorative slurs are used to express both a descriptive belief and a negative attitude. The analogy looks promising insofar as it encourages the kinds of features we should want from a hybrid expressivist view for moral language. But the analogy between moral terms and pejorative slurs (...) is also problematic. In this paper, I argue for two main ways in which we should distinguish between two different types of pejorative terms: slurs, on the one hand, and what I call general pejorative terms, on the other. I examine the problems with the analogy between slurs and moral terms and conclude that general pejorative terms like ‘jerk’ are a better candidate on which to model the potential dual-use behavior of moral terms. So if hybrid theorists are looking for a dual-use model for moral language, they should be careful to base their analogies on general pejoratives, rather than slurs. (shrink)

Hybrid theories are metaethical theories concerning the content of sentences about moral value. These theories claim that sentences with ethical content express two kinds of mental state. One state is an affect‐like state. The other is a belief‐like state. The expressed affect‐like state will involve a moral attitude of some kind, such as approval, but it is not part of the truth‐conditions of the sentence. We can divide hybridists into two kinds.

Finally, for a perspective (...) and debate, we propose some ways to serve these ingenuities. (shrink)

Does the English demonstrative pronoun 'that' (including complex demonstratives of the form 'that F') have sense and reference? Unlike many other philosophers of language, Frege answers with a resounding 'No'. He held that the bearer of sense and reference is a so-called 'hybrid proper name' (Künne) that contains the demonstrative pronoun and specific circumstances of utterance such as glances and acts of pointing. In this paper I provide arguments for the thesis that demonstratives are hybrid proper names. After outlining why (...) Frege held the hybrid proper name view, I will defend it against recent criticism, and argue that it is superior to views that take demonstrative pronouns to be the bearer of semantic properties.

The theory of boundary organizations was developed to address an important group of institutions in American society neglected by scholarship in science studies and political science. The long-term stability of scientific and political institutions in the United States has enabled a new class of institutions to grow and thrive as mediators between the two. As originally developed, this structural feature of these new institutions—that is, their location on the boundary between science and politics—dominated theoretical frame-works for explaining their behavior. Applying (...) the theory of boundary organizations to international society requires a refocusing of some of the theory’s central features, however. In this article, I introduce a new framework—hybrid management—to explain the activities of boundary organizations in the more complex, contingent, and contested settings of global politics. I develop the framework of hybrid management using the specific example of the U.N. Framework Convention on Climate Change’s Subsidiary Body for Scientific and Technological Advice. (shrink)

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)

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)

Hybrid and pluralist accounts of concepts agree that the class of concepts includes a multiplicity of heterogeneous representational structures, such as prototypes, sets of exemplars and theories. In this paper I argue that these accounts agree on two additional central claims related to the ways in which they articulate those structures: each type of representational structure can be used independently in psychological processes, and co-referential concepts are associated in a distinctive way as representations of the same category. Although they disagree (...) on concept individuation, they seem to agree that on a processing dimension there are multiple independent representations for a given category and on a long-term storage dimension concepts that represent the same category conform an epistemic unity.

I examine the warrants we have in light of the empirical successes of a kind of model I call ‘ hybrid models ’, a kind that includes climate models among its members.

I also argue that the warrants in question, unlike those IBE provides, guide inferences only to (...) model implications about which there is real uncertainty. My conclusion provides criteria of adequacy for epistemologies of climate and other hybrid models. (shrink)
