Modal Meinongianism is a form of Meinongianism whose main supporters are Graham Priest and Francesco Berto. The main idea of modal Meinongianism is to restrict the logical deviance of Meinongian non-existent objects to impossible worlds and thus prevent it from “contaminating” the actual world: the round square is round and not round, but not in the actual world, only in an impossible world. In the actual world, supposedly, no contradiction is true. I will show that Priest’s semantics, (...) as originally formulated in Towards Non-being, tell us something different. According to certain models, there are true contradictions in the actual world. Berto and Priest have noticed this unexpected consequence and have suggested a solution, but I will show that their solution is highly questionable. In the last section of this paper, I will introduce a new and simpler version of modal Meinongianism that avoids the problem. (shrink)

We show that classical two-valued logic is included in weak extensions of normal three-valued logics and also that normal three-valued logics are best viewed not as deviant logics but instead as strong extensions of classical two-valued logic obtained by adding a modal operator and the right axioms. This article develops a general method for formulating the right axioms to construct a two-valued system with theorems that correspond to all of the logical truths of any normal three-valued logic. The extended (...) classical system can then express anything that can be expressed in the three-valued logic, so there can be no reason to abandon two-valued logic in favor of three-valued logic. Moreover, the two-valued modal system is preferable, because it enables us to study interactions of different operators with different rationales. It also makes it easier to introduce quantifiers and iteration. Nothing is lost and much is gained by choosing the extended two-valued approach over normal three-valued logics. (shrink)

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)

As part of Timothy Williamson’s inquiry into how we gain knowledge from thought experiments he submits various ways of representing the argument underlying Gettier cases in modal and counterfactual terms. But all of these ways run afoul of the problem of deviance - that there are cases that might satisfy the descriptions given by a Gettier text but still fail to be counterexamples to the justified true belief model of knowledge). Problematically, this might mean that either it is (...) too hard to know the truth of the premises of the arguments Williamson presents or that the relevant premises might be false. I argue that the Gettier-style arguments can make do with weaker premises (and a slightly weaker conclusion) that suffice to show that “necessarily, if one justifiably believes some true proposition p, then one knows p” is not true. The modified version of the argument is preferable because it is not troubled by the existence of deviant Gettier cases. (shrink)

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

Are current theories of moral responsibility missing a factor in the attribution of blame and praise? Four studies demonstrated that even when cause, intention, and outcome (factors generally assumed to be sufficient for the ascription of moral responsibility) are all present, blame and praise are discounted when the factors are not linked together in the usual manner (i.e., cases of ‘‘causal deviance’’). Experiment 4 further demonstrates that this effect of causal deviance is driven by intuitive gut feelings of (...) right and wrong, not logical deliberation.

Most contemporary philosophers of action agree on the following claims. Firstly, the possibility of deviant or wayward causal chains poses a serious problem for the standard-causal theory of action. Secondly, we can distinguish between different kinds of deviant causal chains in the theory of action. In particular, we can distinguish between cases of basic and cases of consequential deviance. Thirdly, the problem of consequential deviance admits of a fairly straightforward solution, whereas the possibility of basic deviance constitutes (...) a separate and difficult problem that requires its own solution. I will argue that the problem of basic deviance is no more troublesome than the problem of consequential deviance, as a solution to the former is implicit in the standard solution to the latter.

Modal ontolojik argüman, Tanrı’nın varlığını sadece bilfiil gerçek olan bu dünyada değil, bütün mümkün dünyalarda göstermeye yönelik bir argümandır. Anselm’in (1033-1109) Proslogion adlı eserinin 3. bölümünde “kendisinden daha büyüğü düşünülemeyen” şeklinde tanımlanan; Tanrı’nın var olmamasının da düşünülemeyeceğini, bu yüzden de varolmamasının imkansızlığı üzerinde kurulu yeni bir argüman bulunduğunu öne süren bazı araştırmacılar, bu argümanı mümkün dünyalar semantiği yardımıyla formüle edip, “modal ontolojik argüman” şeklinde adlandırmışlardır. Çok farklı şekillerde formüle edilmiş bu argüman kabaca Tanrı’nın mümkünse zorunlu olması, dolayısıyla bilfiil (...) gerçek olan bu dünyada da var olması gerektiğini savunur. (shrink)

I argue that we should give up the fight to rescue causal theories of action from fundamental challenges such as the problem of deviant causal chains; and that we should rather pursue an account of action based on the basic intuition that control identifies agency. In Section 1 I introduce causalism about action explanation. In Section 2 I present an alternative, Frankfurt’s idea of guidance. In Section 3 I argue that the problem of deviant causal chains challenges causalism in two (...) important respects: first, it emphasizes that causalism fails to do justice to our basic intuition that control is necessary for agency. Second, it provides countless counterexamples to causalism, which many recent firemen have failed to extinguish – as I argue in some detail. Finally, in Section 4 I argue, contra Al Mele, that control does not require the attribution of psychological states as causes. (shrink)

This paper is about the putative theoretical virtue of strength, as it might be used in abductive arguments to the correct logic in the epistemology of logic. It argues for three theses. The first is that the well-defined property of logical strength is neither a virtue nor a vice, so that logically weaker theories are not—all other things being equal—worse or better theories than logically stronger ones. The second thesis is that logical strength does not entail the looser characteristic of (...) scientific strength, and the third is that many modern logics are on a par—or can be made to be on a par—with respect to scientific strength.

Drawing on the problem of deviance, I present a novel line of argumentation against causal theories of action. The causalist faces a dilemma: either she adopts a simple account of the causal route between intention and outcome, at the cost of failing to rule out deviance cases, or she adopts a more sophisticated account, at the cost of ruling out cases of intentional action in which the causal route is merely unusual. Underlying this dilemma, I argue, is that (...) the agent's perspective plays an ineliminable role in determining which causal pathways are deviant and which are not. (shrink)

We build on the emerging research that shows aversive subordinate workplace behaviors are likely related to abusive supervision in the workplace. Specifically, we develop and test a moderated-mediation model outlining the process of abusive supervision based on the stressor-emotion model of counterproductive work behavior. We argue that subordinate interpersonal deviance prompts supervisor negative emotions, which then leads supervisors to engage in abusive supervision. We also argue that subordinate organizational citizenship behavior (OCB) is likely to play a crucial role in (...) predicting abusive supervision. We argue that interpersonal deviance is more likely to prompt abusive supervision through supervisor negative emotions when the magnitude of an employee’s engagement in OCB is weaker. Study 1, a time-lagged field study, tests and provides support for the relationships among our key variables (Hypotheses 1–3). Study 2, utilizing multisource field data (i.e., subordinate–supervisor dyads), replicates the results from Study 1 and provides support for the entire moderated-mediation model while controlling for tenure with supervisor, subordinate task performance, and subordinate conscientiousness. We find general support for our predictions. We conclude with a discussion of theoretical and practical implications as well as future research directions. (shrink)

A textbook on modal logic, intended for readers already acquainted with the elements of formal logic, containing nearly 500 exercises. Brian F. Chellas provides a systematic introduction to the principal ideas and results in contemporary treatments of modality, including theorems on completeness and decidability. Illustrative chapters focus on deontic logic and conditionality. Modality is a rapidly expanding branch of logic, and familiarity with the subject is now regarded as a necessary part of every philosopher's technical equipment. Chellas here offers (...) an up-to-date and reliable guide essential for the student. (shrink)

Epistemic modal operators give rise to something very like, but also very unlike, Moore's paradox. I set out the puzzling phenomena, explain why a standard relational semantics for these operators cannot handle them, and recommend an alternative semantics. A pragmatics appropriate to the semantics is developed and interactions between the semantics, the pragmatics, and the definition of consequence are investigated. The semantics is then extended to probability operators. Some problems and prospects for probabilistic representations of content and context are (...) explored. (shrink)

Dispositionality is a modal notion of a certain sort. When an object is said to have a disposition, we typically understand this to mean that under certain circumstances, the object would behave in a certain way. For instance, a fragile object is disposed to break when dropped onto a concrete surface. It need not actually break - its being fragile has implications that, so to speak, point beyond the actual world. According to dispositionalism, all modal features of the (...) world may be accounted for in terms of its dispositional features. My aim in this paper is to assess the prospects for dispositionalism by examining the most promising theories. Sections 1 and 2 clarify the assumptions and desiderata of a successful dispositionalist theory of modality. Section 3 introduces the principles governing the dispositionalist theories that apparently meet the desiderata. Sections 4 through 6 show that dispositionalism nonetheless faces three problems: while dispositions help account for modal features of the world that are local, diachronic, or gradable, they cannot account for certain modal features of the world that are global, synchronic, or absolute. I end by discussing the costs of preserving dispositionalism. (shrink)

In recent years, public discourse has largely embraced the idea that persons with addictions have a “brain disease,” and ought to be treated medically rather than judicially. This article first argues that this social shift is mostly the result of middle- and upper-class whites being among the addicted. The medical language is deployed so that such persons avoid the stigma of “deviance” commonly linked to addiction. Second, this article argues for a Christian “holy deviance,” whereby Christians become deviant (...) by going out to those who are already marked by society as deviant, letting the latter know in word and deed that they are loved.

Workplace deviance has long been a subject of discussion in various industries, including the healthcare sector. The poor working conditions in the nursing profession have made nurses feel pressured to perform more than their contractual tasks, resulting in job dissatisfaction, which has prompted them to engage in workplace deviance, which may jeopardize the hospital’s well-being and wealth. The negative behaviors exhibited by the nurses had a significant impact on hospital function, which may also endanger the lives of patients, (...) which is an issue that warrants further investigation. The Pakistani nursing sector has been emphasized by the study due to the different working conditions in Pakistan as compared to Western countries. The nursing profession in Pakistan is different due to its dominant Islamic context. To elucidate the issue, this study aims to examine the influence of destructive leadership behaviors and citizenship pressure on job dissatisfaction among nurses and the influence of job dissatisfaction on workplace deviance. The role of job dissatisfaction as a mediator has also been examined. By adopting the quantitative approach, data were collected from 383 nurses in Pakistani Hospitals. Analysis was done using partial least squares structural equation modeling (PLS-SEM). The findings revealed that citizenship pressure and destructive leadership behaviors (i.e., laissez-faire, supportive-disloyal, and tyrannical leadership) are significant predictors of job dissatisfaction. Job dissatisfaction, in turn, was found to mediate the effect of citizenship pressure and all destructive leadership behaviors, except derailed leadership, on workplace deviance. The findings of the present study are theoretically and practically relevant as they provide new insights into the behavioral mechanisms that could be addressed to eliminate the occurrence of workplace deviance in the healthcare context.

I critically examine the claim that modal collapse arguments against the traditional doctrine of divine simplicity (DDS) are in general fallacious. In a recent paper, Christopher Tomaszewski alleges that modal collapse arguments against DDS are invalid, owing to illicit substitutions of nonrigid singular terms into intensional contexts. I show that this is not, in general, the case. I show, further, that where existing modal collapse arguments are vulnerable to this charge the arguments can be repaired without any (...) apparent dialectical impropriety. I conclude that the genuine debate over modal collapse and divine simplicity and modal collapse is substantially a controversy over the metaphysics of divine action, and that this constitutes a fruitful direction in which to take future discussions of the subject.

This modern, advanced textbook reviews modal logic, a field which caught the attention of computer scientists in the late 1970's.

Recent research on algebraic models of _quasi-Nelson logic_ has brought new attention to a number of classes of algebras which result from enriching (subreducts of) Heyting algebras with a special modal operator, known in the literature as a _nucleus_. Among these various algebraic structures, for which we employ the umbrella term _intuitionistic modal algebras_, some have been studied since at least the 1970s, usually within the framework of topology and sheaf theory. Others may seem more exotic, for their (...) primitive operations arise from algebraic terms of the intuitionistic modal language which have not been previously considered. We shall for instance investigate the variety of _weak implicative semilattices_, whose members are (non-necessarily distributive) meet semilattices endowed with a nucleus and an implication operation which is not a relative pseudo-complement but satisfies the postulates of Celani and Jansana’s strict implication. For each of these new classes of algebras we establish a representation and a topological duality which generalize the known ones for Heyting algebras enriched with a nucleus. (shrink)

The Calvinist view that man is predestined to be among the elect or the damned has profoundly influenced not only our views of criminals and deviants, but also the theoretical basis of correctional methods and psychotherapeutic techniques. In this provocative and original volume, Mordechai Rotenberg examines the impact of Protestant doctrine on Western theories of deviance. He explores the inherent contradiction between Protestant ethics, with its view of human nature as predestinated, and the "people-changing" sciences.Rotenberg presents empirical studies that (...) show how people's tendency to label themselves and others as deviant can be predicted on the basis of their exposure to Western socialization. He contrasts alienating individuals, the result of competitiveness and exaggerated independence fostered by socialization in Protestant societies, to the reciprocal individualism of Hassidic, Japanese, and other non-Western cultures. Examining the Protestant "bias" of Western behavioral sciences, Rotenberg examines modern theories of deviance and proposes alternative models. He compares traditional past-oriented insight therapy, grounded in Calvinist methods of introspection, self-torment, and conversion, with Hassidic notions of redemption and salvation."Rotenberg provides important historical and sociological insights into the intellectual origins of modern theories of deviance. His argument that Western behavioral science retains a Calvinist view of humanity will force most scholars to examine anew the assumptions and foundations of their own theories."--Gerald N. Grob, Rutgers University"A highly original work, which should be of great interest to anyone concerned with relevant behavior. It shows how macro-definitions in a society tend to lead people to think about themselves and their ills in certain ways--and thus to deviate in certain ways."--Richard A.

Proof Theory of Modal Logic is devoted to a thorough study of proof systems for modal logics, that is, logics of necessity, possibility, knowledge, belief, time, computations etc. It contains many new technical results and presentations of novel proof procedures. The volume is of immense importance for the interdisciplinary fields of logic, knowledge representation, and automated deduction.

Causal theories of action, perception and knowledge are each beset by problems of so-called ‘deviant’ causal chains. For each such theory, counterexamples are formed using odd or co-incidental causal chains to establish that the theory is committed to unpalatable claims about some intentional action, about a case of veridical perception or about the acquisition of genuine knowledge. In this paper I will argue that three well-known examples of a deviant causal chain have something in common: they each violate Yablos proportionality (...) constraint on causation. I will argue that this constraint provides the key to saving causal theories from deviant chains. (shrink)

There is a lot that we don't know. That means that there are a lot of possibilities that are, epistemically speaking, open. For instance, we don't know whether it rained in Seattle yesterday. So, for us at least, there is an epistemic possibility where it rained in Seattle yesterday, and one where it did not. What are these epistemic possibilities? They do not match up with metaphysical possibilities - there are various cases where something is epistemically possible but not metaphysically (...) possible, and vice versa. How do we understand the semantics of statements of epistemic modality? The ten new essays in this volume explore various answers to these questions, including those offered by contextualism, relativism, and expressivism. (shrink)

While organizational deviance has become a popular research topic in the past two decades, deviant behavior remains a contested concept, with several research studies being done to better define the term. As a result, researchers have introduced various definitions and constructs which seem to overlap one another. Such proliferation might backfire and could lead to more confusion. Looking at deviance from an ontological aspect, therefore, will help to decrease such confusion among researchers. Another advantage to ontologically viewing (...) class='Hi'>deviance is that it provides a better understanding of the concept. To prevent deviance occurring within an organization, the first step is learning more about it. This study therefore aims to discover how researchers can use ontological view to provide a better understanding of deviance, thus creating a deviance-free climate within an organization. This study looks at the role of storytelling in sharing norms within an organization to provide such a deviance-free climate. (shrink)

Boris Kment takes a new approach to the study of modality that emphasises the origin of modal notions in everyday thought. He argues that the concepts of necessity and possibility originate in counterfactual reasoning, which allows us to investigate explanatory connections. Contrary to accepted views, explanation is more fundamental than modality.

I defend the claim that we have the capacity to perceptually represent objects and events in experience as deviating from an expectation, or, for short, as deviant. The rival hypothesis is that we may ascribe the property of deviance to a stimulus at a cognitive level, but that property is not a representational content of perceptual experience. I provide empirical reasons to think that, contrary to the rival hypothesis, we do perceptually represent deviance.

In the middle of the last century, it was common to explain the notion of necessity in linguistic terms. A necessary truth, it was said, is a sentence whose truth is guaranteed by linguistic rules. Quine famously argued that, on this view, de re modal claims do not make sense. “Porcupettes are porcupines” is necessarily true, but it would be a mistake to say of a particular porcupette that it is necessarily a porcupine, or that it is possibly purple. (...) Linguistic theories of necessity fell out of favour with the publication of Kripke’s Naming and Necessity, and Quine’s arguments were put aside. In her recent book, Norms and Necessity, Amie Thomasson presents her modal normativism, which is an updated version of the mid-century theories just described. Quine’s arguments are thus relevant once again. We recapitulate Quine’s central argument, in the context of modal normativism. We then criticise Amie Thomasson’s discussion of de re modality. We finish by briefly presenting an alternative account of de re modal statements, which is compatible with modal normativism. (shrink)

Most Probably: Epistemic Modality in Old Babylonian by Nathan Wasserman is the first attempt to provide a description of the domain of epistemic modality in Old Babylonian Akkadian. This attempt is not entirely successful, for several reasons. Methodological inconsistency often impairs the author’s ability to convince the reader of his solutions. Both primary data and existing secondary literature are used only selectively, which renders the proposed description problematic. Finally, the lack of cross-referencing between the chapters evokes the feeling that the (...) different particles do not quite constitute a system. (shrink)
