The aggregation of individual judgments on logically interconnected propositions into a collective decision on the same propositions is called judgment aggregation. Literature in social choice and political theory has claimed that judgment aggregation raises serious concerns. For example, consider a set of premises and a conclusion where the latter is logically equivalent to the former. When majority voting is applied to some propositions (the premises) it may give a different outcome than majority voting applied to another set of propositions (the (...) conclusion). This problem is known as the discursive dilemma (or paradox). The discursive dilemma is a serious problem since it is not clear whether a collective outcome exists in these cases, and if it does, what it is like. Moreover, the two suggested escape-routes from the paradox—the so-called premise-based procedure and the conclusion-based procedure—are not, as I will show, satisfactory methods for group decision-making. In this paper I introduce a new aggregation procedure inspired by an operator defined in artificial intelligence in order to merge belief bases. The result is that we do not need to worry about paradoxical outcomes, since these arise only when inconsistent collective judgments are not ruled out from the set of possible solutions. (shrink)

The paper discusses ten philosophical problems in deontic logic: how to formally represent norms, when a set of norms may be termed ‘coherent’, how to deal with normative conflicts, how contraryto-duty obligations can be appropriately modeled, how dyadic deontic operators may be redefined to relate to sets of norms instead of preference relations between possible worlds, how various concepts of permission can be accommodated, how meaning postulates and counts-as conditionals can be taken into account, and how sets of norms may (...) be revised and merged. The problems are discussed from the viewpoint of input/output logic as developed by van der Torre & Makinson. We argue that norms, not ideality, should take the central position in deontic semantics, and that a semantics that represents norms, as input/output logic does, provides helpful tools for analyzing, clarifying and solving the problems of deontic logic.

The Ostrogorski paradox and the discursive dilemma are seemingly unrelated paradoxes of aggregation. The former is discussed in traditional social choice theory, while the latter is at the core of the new literature on judgment aggregation. Both paradoxes arise when, in a group, each individual consistently makes a judgment, or expresses a preference, (in the form of yes or no) over specific propositions, and the collective outcome is in some respect inconsistent. While the result is logically inconsistent in the case (...) of the discursive paradox, it is not stable with respect to the level of aggregation in the case of the Ostrogorski paradox. In the following I argue that, despite these differences, the two problems have a similar structure. My conclusion will be twofold: on the one hand, the similarities between the paradoxes support the claim that these problems should be tackled using the same aggregation procedure; on the other hand, applying the same procedure to these paradoxes will help clarify the strengths and weaknesses of the aggregation method itself. More specifically, I will show that an operator defined in artificial intelligence to merge belief bases can deal with both paradoxes. (shrink)

There exist important deductive systems, such as the non-normal modal logics, that are not proper subjects of classical algebraic logic in the sense that their metatheory cannot be reduced to the equational metatheory of any particular class of algebras. Nevertheless, most of these systems are amenable to the methods of universal algebra when applied to the matrix models of the system. In the present paper we consider a wide class of deductive systems of this kind called protoalgebraic logics. These include (...) almost all (non-pathological) systems of prepositional logic that have occurred in the literature. The relationship between the metatheory of a protoalgebraic logic and its matrix models is studied. The following results are obtained for any finite matrix model U of a filter-distributive protoalgebraic logic : (I) The extension U of is finitely axiomatized (provided has only finitely many inference rules); (II) U has only finitely many extensions.

In this comprehensive new study of human free agency, Laura Waddell Ekstrom critically surveys contemporary philosophical literature and provides a novel account of the conditions for free action. Ekstrom argues that incompatibilism concerning free will and causal determinism is true and thus the right account of the nature of free action must be indeterminist in nature. She examines a variety of libertarian approaches, ultimately defending an account relying on indeterministic causation among events and appealing to agent causation only in (...) a reducible sense. Written in an engaging style and incorporating recent scholarship, this study is critical reading for scholars and students interested in the topics of motivation, causation, responsibility, and freedom. In broadly covering the important positions of others along with its exposition of the author’s own view, Free Will provides both a significant scholarly contribution and a valuable text for courses in metaphysics and action theory.

The orthodox view of anger takes desires for revenge or retribution to be central to the emotion. In this paper, I develop an empirically informed challenge to the retributive view of anger. In so doing, I argue that a distinct desire is central to anger: a desire for recognition. Desires for recognition aim at the targets of anger acknowledging the wrong they have committed, as opposed to aiming for their suffering. In light of the centrality of this desire for recognition, (...) I argue that the retributive view of anger should be abandoned. I consider and dismiss two types of moves that can be made on the part of a proponent of the orthodox view in response to my argument. I propose that a pluralist view, which allows for both retribution and recognition in anger, is to be preferred. (shrink)

According to Frege's principle the denotation of a sentence coincides with its truth-value. The principle is investigated within the context of abstract algebraic logic, and it is shown that taken together with the deduction theorem it characterizes intuitionistic logic in a certain strong sense.A 2nd-order matrix is an algebra together with an algebraic closed set system on its universe. A deductive system is a second-order matrix over the formula algebra of some fixed but arbitrary language. A second-order matrix A is (...) Fregean if, for any subset X of A, the set of all pairs a,b such that X{a} and X{b} have the same closure is a congruence relation on A. Hence a deductive system is Fregean if interderivability is compositional. The logics intermediate between the classical and intuitionistic propositional calculi are the paradigms for Fregean logics. Normal modal logics are non-Fregean while quasi-normal modal logics are generally Fregean.The main results of the paper: Fregean deductive systems that either have the deduction theorem, or are protoalgebraic and have conjunction, are completely characterized. They are essentially the intermediate logics, possibly with additional connectives. All the full matrix models of a protoalgebraic Fregean deductive system are Fregean, and, conversely, the deductive system determined by any class of Fregean second-order matrices is Fregean. The latter result is used to construct an example of a protoalgebraic Fregean deductive system that is not strongly algebraizable. (shrink)

ABSTRACTRecent research suggests that impaired emotion regulation may play an important role in the development of youth psychopathology. However, little research has explored the effects of ER strategies on affect in early adolescents. In Study 1, we examined if early adolescents are able to use distraction and whether the effects of this strategy are similar to talking to one’s mother. In Study 2, we compared the effects of distraction, cognitive reappraisal, acceptance, and rumination. In both studies, participants received instructions on (...) how to regulate their emotions after a standardised negative mood induction. In general, the results indicated that distraction, but also cognitive reappraisal and acceptance, had promising short-term effects on positive and negative affect in early adolescents. These findings suggest that targeting adaptive ER skills, such as distraction, acceptance, and cognitive reappraisal, may be an important strategy to prevent or treat psychological pro... (shrink)

Judgment aggregation studies how individual opinions on a given set of propositions can be aggregated to form a consistent group judgment on the same propositions. Despite the simplicity of the problem, seemingly natural aggregation procedures fail to return consistent collective outcomes, leading to what is now known as the doctrinal paradox. The first occurrences of the paradox were discovered in the legal realm. However, the interest of judgment aggregation is much broader and extends to political philosophy, epistemology, social choice theory, (...) and computer science. The aim of this paper is to provide a concise survey of the discipline and to outline some of the most pressing questions and future lines of research. (shrink)

The aggregation of consistent individual judgments on logically interconnected propositions into a collective judgment on the same propositions has recently drawn much attention. Seemingly reasonable aggregation procedures, such as propositionwise majority voting, cannot ensure an equally consistent collective conclusion. The literature on judgment aggregation refers to such a problem as the \textit{discursive dilemma}. In this paper we assume that the decision which the group is trying to reach is factually right or wrong. Hence, we address the question of how good (...) the various approaches are at selecting the right conclusion. We focus on two approaches: distance-based procedures and a Bayesian analysis. They correspond to group-internal and group-external decision-making, respectively. We compare those methods in a probabilistic model, demonstrate the robustness of our results over various generalizations and discuss their applicability in different situations. The findings vindicate (i) that in judgment aggregation problems, reasons should carry higher weight than conclusions and (ii) that considering members of an advisory board to be highly competent is a better strategy than to underestimate their advice.".

While various definitions of moral distress have been proposed, some agreement exists that it results from illegitimate constraints in clinical practice affecting healthcare professionals’ moral agency. If we are to reduce moral distress, instruments measuring it should provide relevant information about such illegitimate constraints. Unfortunately, existing instruments fail to do so. We discuss here several shortcomings of major instruments in use: their inability to determine whether reports of moral distress involve an accurate assessment of the requisite clinical and logistical facts (...) in play, whether the distress in question is aptly characterized as moral, and whether the moral distress reported is an appropriate target of elimination. Such failures seriously limit the ability of empirical work on moral distress to foster appropriate change. (shrink)

"This book focuses on arguments from suffering against the existence of God and on a variety of issues concerning agency and value that they bring out. The central aim is to show the extent and power of arguments from evil. The book provides a close investigation of an under-defended claim at the heart of the major free-will-based responses to such arguments, namely that free will is sufficiently valuable to serve as the good, or prominently among the goods, that provides a (...) God-justifying reason for permitting evil in our world. Offering a fresh examination of traditional theodicies, it also develops an alternative line the author calls a divine intimacy theodicy. It makes an extended case for rejection of the position of skeptical theism. The book expands upon an argument from evil concerning a traditional doctrine of hell, which reveals a number of interesting issues concerning fault, agency, and blameworthiness. In response to recent work contending that the problem of evil is defanged since God's baseline attitude toward human beings is indifference, the book defends the essential perfect moral goodness of God. Finally it takes up the question of whether or not it makes sense to live a religious life as an agnostic or as an atheist"--. (shrink)

Formal arguments are often represented by pairs, but in this paper we consider normative arguments represented by sequences of triples, where constitutive norms derive institutional facts from brute facts, and regulative norms derive deontic facts like obligations and permissions from institutional facts. The institutional facts may be seen as the reasons explaining or warranting the deontic obligations and permissions, and therefore they can be attacked by other normative arguments too. We represent different aspects of normative reasoning by different kinds of (...) consistency checks among these triples, and we use formal argumentation theory to resolve conflicts among such normative arguments. In particular, we introduce various requirements for arguing about norms concerning violations, contrary-to-duty obligations, dilemmas, conflict resolution and different kinds of norms, and we introduce a formal argumentation theory satisfying the requirements. In order to illustrate our framework, we introduce a running example based on university regulations for prospective and actual students. (shrink)

Outlaw emotions are emotions that stand in tension with one’s wider belief system, often allowing epistemic insight one may have otherwise lacked. Outlaw emotions are thought to play crucial epistemic roles under conditions of oppression. Although the crucial epistemic value of these emotions is widely acknowledged, specific accounts of their epistemic role(s) remain largely programmatic. There are two dominant accounts of the epistemic role of emotions: The Motivational View and the Justificatory View. Philosophers of emotion assume that these dominant ways (...) of accounting for the epistemic role(s) of emotions in general are equipped to account for the epistemic role(s) of outlaw emotions. I argue that this is not the case. I consider and dismiss two responses that could be made on behalf of the most promising account, the Justificatory View, in light of my argument, before sketching an alternative account that should be favoured.

Anger is often an appropriate reaction to harms and injustices, but is it a politically beneficial one? Martha Nussbaum (Journal of the American Philosophical Association 1 (1), 41–56, 2015, Anger and Forgiveness. Oxford University Press, 2016) has argued that, although anger is useful in initially recruiting agents for action, anger is typically counterproductive to securing the political aims of those harmed. After the initial shockwave of outrage, Nussbaum argues that to be effective at enacting positive social change, groups and individuals (...) alike, must move quickly out of the state of anger. Feminist theorists (Frye, The Politics of Reality. Crossing Press, 1983; Lorde, 1997; Narayan, Hypatia 3 (2): 31–48, 1988) on the other hand have for long highlighted the efficacy of anger, as well as its moral and epistemic value, in fighting against the oppressive status quo. It might be thought therefore that for political action to be effective, a continued state of anger is preferable. Protestors must after all create and sustain a sense of moral obligation and justice. A main way of doing so is to promote successive moral shocks that trigger outrage (Jasper, Emotion Review 6 (3): 208–213, 2014). I present a novel, empirically informed defense of anger’s efficacy in political action. Nussbaum holds a traditional view on the nature of anger, inherited from Aristotle and the Stoics, which holds that anger constitutively involves a desire for retribution. The view that anger is counterproductive falls out of this and is dominant in academic work as well as in our personal and political lives. Based on work in social psychology, I argue that we need to reconsider this. In doing so, I highlight anger’s aim for recognition, rather than retribution, as key. Furthermore, I uncover conditions for anger’s political efficacy, as well as reasons for why the traditional view of anger has been so pervasive. (shrink)

In this paper we explore the relation between three areas: judgment aggregation, belief merging and social choice theory. Judgment aggregation studies how to aggregate individual judgments on logically interconnected propositions into a collective decision on the same propositions. When majority voting is applied to some propositions it may however give a different outcome than majority voting applied to another set of propositions. Starting from this so-called doctrinal paradox, the paper surveys the literature on judgment aggregation, and shows that the application (...) of a well known belief merging operator can dissolve the paradox. Finally, the use of distances is shown to establish a link between belief merging and preference aggregation in social choice theory. (shrink)

In this article I argue that characterizations of anger as a hostile emotion may be mistaken. My project is empirically informed and is partly descriptive, partly diagnostic. It is descriptive in that I am concerned with what anger is, and how it tends to manifest, rather than with what anger should be or how moral anger is manifested. The orthodox view on anger takes it to be, descriptively, an emotion that aims for retribution. This view fits well with anger being (...) a hostile emotion, as retribution is punitive. I will argue that a different view of anger deserves our attention. On this alternative view, anger aims for recognition of harms done, rather than for the punishment of those who have committed them. I argue that we have reason to favour a strong view that excludes retribution from anger’s main aims. In addition, I offer a diagnosis of the reasons that led the retributive view of anger to become, and remain, orthodoxy. This diagnosis provides indirect reason to give my descriptive proposal serious consideration, for it highlights that the orthodox view has dominated folk and philosophical conceptions of anger for reasons that do not speak in favour of the view’s veracity. The view that anger is a hostile emotion will therefore emerge as in need of serious scrutiny. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Theory in the “Post” Era: A Vocabulary for the 21st-Century Conceptual Commons ed. by Alexandru Matei, Christian Moraru and Andrei TerianLaura Elena Savu WalkerMatei, Alexandru, Christian Moraru, and Andrei Terian, editors. Theory in the “Post” Era: A Vocabulary for the 21st-Century Conceptual Commons. Bloomsbury, 2021. 376pp.Far from “mourning” the demise of theory, this timely and thoughtfully curated essay collection testifies to its “renewed vitality,” its compelling presence “across (...) fields, domains of life, and geocultural boundaries,” and its power to build an ever-expanding world community of practioners who are forming what has come to be known as a “theory commons” (ix). As the collection’s editors point out, theory’s new lease on life hinges on ensuring both the democratic workings of this “world discourse formation” (1) and on the responsible theorizing of the very notion of community in “a world threatened by all kinds of anti-communal actions and reactions, from runaway globalization to exacerbated tribalism and tunnel-vision politics” (x). Working on the margins, specifically, out of a Romanian “lab” called The Critical Theory Institute (CTI), which opened its doors in early 2000, the contributors seek to revise the “standard history of theory,” one whose “Western origins, authority, and cultural compass ” strike them as “exceedingly reductive” (3). This project of geotheoretical repositioning and recalibration aims to recast theory as a “quintessentially cross-linguistic, cross-cultural, trans- and intercontinental undertaking” (4). As such, it carries on the project, launched in a previous volume, Romanian Literature as World Literature (2018), of fashioning an alternative to the nation-state paradigm that has long shaped literary and intellectual histories. In both of these works, Romanian critics and theorists have tuned into a wide range of voices, and tapped into a shared conceptual and methodological apparatus—itself the product of “an ethno-linguistic medley of traditions” (8). This approach informs what editors see as the “epoch-making” (17) discursive paradigm that has taken shape in globally networked post-Cold War societies (17), a viral model of cultural influence that fosters an ontology of “contact, contagion, of infection, dissemination, and horizontal accumulation” (15).To give us a sense of theory’s complex genealogy and evolution, the editors reference the Bulgarian critic Galin Tihanov, who has attributed [End Page 122] important developments in contemporary theory to the achievements of theorists (Nikolai Trubetskoi, Roman Jakobson, Vladimir Propp, and Georg Lukács) and schools of thought (Russian Formalism and the Prague Linguistic Circle). In “Traveling Theory” (1983) and “Traveling Theory Reconsidered” (2000), Edward Said called attention to the migratory nature of contributions made, for instance, by Georg Lukács, whose theories moved across different European locales in this period. Since then, contemporary theory has branched out to integrate the travels and travails of scholars affiliated with theory labs located in Bulgaria, Hungary, Slovakia, and last, but not least, Romania (10).Theory in the “Post” Era highlights five characteristics that distinguish theory in the “post” era from earlier forms: 1) It has a “reluctantly epoch-alist” thrust (19; original italics), which assumes that the “post” lexicon entails “rupture, discontinuity, and opposition” (19), radical departures, tentative claims, provisional conclusions, and ex-centric perspectives; 2) it adopts a “self-reflexive and experimental” (20; original italics) stance in which theorists invoke inherited approaches or invent new ones; 3) it introduces a “transdisciplinary” (21; original italics) scope that allows authors to interrogate the foundations, aims, and methods of theoretical discourse and practice across several knowledge domains, from which they “borrow whole vocabularies and toolkits” (21); 4) it is “nationally, transnationally, and ecologically affiliative” (20) in ways that allow theorists to “think with others at a distance” (21) about global issues; and 5) it is programmatic, placing critical and theoretical concerns in the service of “the ethical, the political, and the communal” (22). Organized around three main themes (“Aesthetics,” “Temporalities,” and “Critical Modes”), the essays juxtapose discussions of pivotal historical events and cultural phenomena with literary analyses of Romantic era “classics,” modernist experiments, and postmodern works of the post-Communist era, a corpus that includes, but is not limited to, landmark works of national culture that are now part of a fast-expanding planetary...

After showing these obstacles to be surmountable, I propose a number of conditions and methodological constraints that should be satisfied in attempts to (...) construct an affective quality space.

While the volume rests on the assumption that science is not autonomous, the book is distinguished by its global perspective.

Anti-individualists claim that concepts are individuated with an eye to purely external facts about a subject's environment about which she may be ignorant or mistaken. This paper offers a novel reason for thinking that anti-individualistic concepts are an ineliminable part of commonsense psychology. Our commitment to anti-individualism, I argue, is ultimately grounded in a rational epistemic agent's commitment to refining her own representational practices in the light of new and surprising information about her environment. Since anti-individualism is an implicit part (...) of responsible epistemic practices, we cannot abandon it without compromising our own epistemic agency. The story I tell about the regulation of one's own representational practices yields a new account of the identity conditions for anti-individualistic concepts. (shrink)

Deep brain stimulation is a well-accepted treatment for movement disorders and is currently explored as a treatment option for various neurological and psychiatric disorders. Several case studies suggest that DBS may, in some patients, influence mental states critical to personality to such an extent that it affects an individual’s personal identity, i.e. the experience of psychological continuity, of persisting through time as the same person. Without questioning the usefulness of DBS as a treatment option for various serious and treatment refractory (...) conditions, the potential of disruptions of psychological continuity raises a number of ethical and legal questions. An important question is that of legal responsibility if DBS induced changes in a patient’s personality result in damage caused by undesirable or even deviant behavior. Disruptions in psychological continuity can in some cases also have an effect on an individual’s mental competence. This capacity is necessary in order to obtain informed consent to start, continue or stop treatment, and it is therefore not only important from an ethical point of view but also has legal consequences. Taking the existing literature and the Dutch legal system as a starting point, the present paper discusses the implications of DBS induced disruptions in psychological continuity for a patient’s responsibility for action and competence of decision and raises a number of questions that need further research.

This paper proposes a new relational account of concepts and shows how it is particularly well suited to characterizing normative concepts. The key advantage of our ‘connectedness’ model is that it explains how subjects can share the same normative concepts despite radical divergences in the descriptive or motivational commitments they associate with them. The connectedness model builds social and historical facts into the foundations of concept identity. This aspect of the model, we suggest, reshapes normative epistemology and provides new resources (...) for a vindication of realism in ethics. (shrink)

The multiterm deduction-detachment theorem is a natural generalization of the (...) deduction theorem of the classical and intuitionistic propositional calculi (IPC) in which a finite system of possibly compound formulas collectively plays the role of the implication connective of IPC. We investigate the deductive structure of Fregean deductive systems with the multiterm deduction-detachment theorem within the framework of abstract algebraic logic. It is shown that each deductive system of this kind has a deductive structure very close to that of the implicational fragment of IPC. Moreover, it is algebraizable and the algebraic structure of its equivalent quasivariety is very close to that of the variety of Hilbert algebras. The equivalent quasivariety is however not in general a variety. This gives an example of a relatively point-regular, congruence-orderable, and congruence-distributive quasivariety that fails to be a variety, and provides what apparently is the first evidence of a significant difference between the multiterm deduction-detachment theorem and the more familiar form of the theorem where there is a single implication connective.

This paper presents and discusses a novel approach to indeterministic belief revision. An indeterministic belief revision operator assumes that, when an agent is confronted with a new piece of information, it can revise its belief sets in more than one way. We define a rational agent not only in terms of what it believes but also of what it desires and wants to achieve. Hence, we propose that the agent’s goals play a role in the choice of (possibly) one of (...) the several available revision options. Properties of the new belief revision mechanism are also investigated. (shrink)

Lewis’ Principal Principle (PP) aims at clarifying the connection between chance (i.e. objective probability) and credence (i.e. subjective probability). It is generally assumed that the chance that an event will occur does not depend on our credence in the occurrence of that event. Nevertheless, chances constrain our credence, and Lewis’ PP is an attempt to capture this connection.

Theabstract variable binding calculus (VB-calculus) provides a formal frame-work encompassing such diverse variable-binding phenomena as lambda abstraction, Riemann integration, existential and universal quantification (in both classical and nonclassical logic), and various notions of generalized quantification that have been studied in abstract model theory. All axioms of the VB-calculus are in the form of equations, but like the lambda calculus it is not a true equational theory since substitution of terms for variables is restricted. A similar problem with the standard formalism (...) of the first-order predicate logic led to the development of the theory of cylindric and polyadic Boolean algebras. We take the same course here and introduce the variety of polyadic VB-algebras as a pure equational form of the VB-calculus. In one of the main results of the paper we show that every locally finite polyadic VB-algebra of infinite dimension is isomorphic to a functional polyadic VB-algebra that is obtained from a model of the VB-calculus by a natural coordinatization process. This theorem is a generalization of the functional representation theorem for polyadic Boolean algebras given by P. Halmos. As an application of this theorem we present a strong completeness theorem for the VB-calculus. More precisely, we prove that, for every VB-theory T that is obtained by adjoining new equations to the axioms of the VB-calculus, there exists a model D such that T s=t iff D s=t. This result specializes to a completeness theorem for a number of familiar systems that can be formalized as VB-calculi. For example, the lambda calculus, the classical first-order predicate calculus, the theory of the generalized quantifierexists uncountably many and a fragment of Riemann integration. (shrink)

The problem of the aggregation of inputs coming from different sources arises in several contexts. Examples are the combination of individual preferences (studied in social choice theory), opinions (judgment aggregation), and data (artificial intelligence). While a number of results are available in each of these disciplines, a question that has been addressed only recently is how similar these aggregation problems are, despite the different types of inputs they try to combine.

How does violence shape citizens’ preferences for conflict termination? The existing literature has argued that violence either begets sympathy for more violence or drives support for making peace. Focusing on the 2016 Colombian Peace Agreement, this article finds that victimhood dissociation strongly shapes these preferences. With victimhood dissociation, a discrepancy exists between objective and subjective victimization, and the effect of violence on peace attitudes depends on citizens’ subjective interpretations of their personal experiences of violence. Citizens who do not experience violence (...) often see themselves as victims of the conflict and vice versa. Victimhood dissociation is linked to cultural stereotypes of victimhood as portrayed in elite narratives concerning the conflict. In Colombia, political leaders framed victimhood around rurality, business entrepreneurship, kidnapping, extortion, and disappearance. In 2016, this widespread narrative was instrumental for politicians opposing the peace agreement. Citizens who disassociated their personal experiences of violence from their self-understanding as victims were instrumental to the failure of the peace plebiscite. (shrink)

For those who maintain that free will is incompatible with causal determinism, a persistent problem is to give a coherent characterization of action that is neither determined by prior events nor random, arbitrary, lucky or in some way insufficiently under the control of the agent to count as free action. One approach—that of Roderick Chisholm and others—is to say that a third alternative is for an action to be caused by an agent in a way that is not reducible to (...) event causal terms. A different approach than the Chisholmian appeal to primitive substance causation is one that, instead, involves causal relations purely among events. This paper presents a particular event-causal indeterminist account of free action, describing both its attractions and recent objections to it, and then proposes a revised version, with the aim of supporting the plausibility of an event-causal indeterminist approach to free will.

: Although "brain death" and the dead donor rule—i.e., patients must not be killed by organ retrieval—have been clinically and legally accepted in the U.S. as prerequisites to organ removal, there is little data about public attitudes and beliefs concerning these matters. To examine the public attitudes and beliefs about the determination of death and its relationship to organ transplantation, 1351 Ohio residents ≥18 years were randomly selected and surveyed using random digit dialing (RDD) sample frames. The RDD telephone survey (...) was conducted using computer-assisted telephone interviews. The survey instrument was developed from information provided by 12 focus groups and a pilot study of the questionnaire. Three scenarios based on hypothetical patients were presented: "brain dead," in a coma, or in a persistent vegetative state (PVS). Respondents provided personal assessments of whether the patient in each scenario was dead and their willingness to donate that patient's organs in these circumstances. More than 98 percent of respondents had heard of the term "brain death," but only one-third (33.7%) believed that someone who was "brain dead" was legally dead. The majority of respondents (86.2%) identified the "brain-dead" patient in the first scenario as dead, 57.2 percent identified the patient in a coma as dead (Scenario 2), and 34.1 percent identified the patient in a PVS as dead (Scenario 3). Nearly one-third (33.5%) were willing to donate the organs of patients they classified as alive for at least one scenario, in seeming violation of the dead donor rule. Most respondents were not willing to violate the dead donor rule, although a substantial minority was. However, the majority of respondents were unaware, misinformed, or held beliefs that were not congruent with current definitions of "brain death." This study highlights the need for more public dialogue and education about "brain death" and organ donation. (shrink)

It's widely accepted that social facts about an individual's linguistic community can affect both the reference of her words and the concepts those words express. Theorists sympathetic to the internalist tradition have sought to accommodate these social dependence phenomena without altering their core theoretical commitments by positing deferential reference-fixing criteria. In this paper, we sketch a different explanation of social dependence phenomena, according to which all concepts are individuated in part by causal-historical relations linking token elements of thought.

Two-dimensional (2D) semantics is a formal framework that is used to characterize the meaning of certain linguistic expressions and the entailment relations among sentences containing them. 2D semantics has also been applied to thought contents. In contrast with standard possible worlds semantics, 2D semantics assigns extensions and truth-values to expressions relative to two possible world parameters, rather than just one. So a 2D semantic framework provides finer-grained semantic values than those available within standard possible world semantics, while using the same (...) basic model-theoretic resources. The 2D framework itself is just a formal tool. To develop a semantic theory for someone’s language, a proponent of 2D semantics must do three things: (i) explain what exactly the two possible world parameters represent, (ii) explain the rules for assigning 2D semantic values to a person’s words and sentences, and (iii) explain how 2D semantic values help in understanding the meanings of the person’s words and sentences.
