Between 15 and 60% of patients are considered ?difficult? by their treating physicians. Patient psychiatric pathology is the conventional explanation for why patients are deemed ?difficult.? But the prevalence of the problem suggests the possibility of a less pathological cause. I argue that the phenomenon can be better explained as a response to problematic interactions related to health care delivery. If there are grounds to reconceive the ?difficult? patient as reacting to the perception of ill treatment, then there is an (...) ethical obligation to address this perception of harm. Resolution of such conflicts currently lies with the provider and patient. But the ethical stakes place these conflicts into the province of the ethics consult service. As the resource for addressing ethical dilemmas, there is a moral mandate to offer assistance in the resolution of these ethically charged conflicts that is no less pressing than the more familiar terrain of clinical ethics consultation.

I present a formal theory of the logic and aboutness of imagination. Aboutness is understood as the relation between meaningful items and what they concern, as per Yablo and Fine’s works on the notion. Imagination is understood as per Chalmers’ positive conceivability: the intentional state of a subject who conceives that p by imagining a situation—a configuration of objects and properties—verifying p. So far aboutness theory has been developed mainly for linguistic representation, but it is natural to extend it to (...) intentional states. The proposed framework combines a modal semantics with a mereology of contents: imagination operators are understood as variably strict quantifiers over worlds with a content-preservation constraint.

Unification was originally introduced in automated deduction and term rewriting, but has recently also found applications in other fields. In this article, we give a survey of the results on unification obtained in two closely related, yet different, application areas of unification: description logics and modal logics.

Many clinical ethics services issue recommendations about ethical controversies that arise in patient care. Their role is configured to be arbiters of moral permissibility, rendering verdicts on which option of those available constitute the morally superior course of action. They produce moral judgements on questions, such as: Should dialysis be started or foregone? Should life-sustaining care be withdrawn or continued? Is it permissible for the clinician to refuse a course of treatment desired by a particular patient or family? But decisions (...) in such cases presume a type of expertise that ethics consultants do not plausibly possess: i.e., the insight to know whose values – which ethical priorities – should trump in situations that are morally ambiguous and normatively contested. This is especially worrisome against the backdrop of the values-pluralism that exists in diverse, heterogeneous societies. This kind of authoritative response to moral uncertainty teeters on hubris, and can have a profoundly negative impact on the lives touched by these decisions. This chapter will argue that the moral arrogance that stems from a conviction of expertise is one of the gravest dangers of contemporary clinical ethics consultation. (shrink)

Clinical ethics consultations are sometimes deemed complete at the moment when the consultants make a recommendation. In CECs that involve actual ethical conflict, this view of a consult's endpoint runs the risk of overemphasizing the conflict's resolution at the expense of the consult's process, which can have deleterious effects on the various parties in the conflict. This overly narrow focus on reaching a decision or recommendation in consults that involve profound moral disagreement can result in two types of adverse, lingering (...) sequelae: moral distress or negative moral emotions. The problem, succinctly named, is that such consults have insufficient “closure” for patients, families, and providers. To promote closure, and avoid the ills of moral distress and the moral emotions, I argue that CECs need to prioritize assisted conversation between the different stakeholders in these conflicts, what is often referred to as “bioethics mediation.”.

Long used as a tool for medical compliance and adhering to treatment plans, behavior contracts have made their way into the in-patient healthcare setting as a way to manage the “difficult” patient and family. The use of this tool is even being adopted by healthcare ethics consultants (HECs) in US hospitals as part of their work in navigating conflict at the bedside. Anecdotal evidence of their increasing popularity among clinical ethicists, for example, can be found at professional bioethics meetings and (...) conversations and idea-sharing among practitioners on HEC social media. While there are a handful of papers gesturing toward a bioethical critique of behavior contracts of various types, the use of behavior contracts in the context of interpersonal conflict has not been vetted by bioethicists to determine their ethical legitimacy or efficacy. In this paper, we highlight a set of ethical concerns that we believe must be addressed before continuing or widespread implementation of behavior contracts to manage the “difficult” patient or family.

We propose a new account of indicative conditionals, giving acceptability and logical closure conditions for them. We start from Adams’ Thesis: the claim that the acceptability of a simple indicative equals the corresponding conditional probability. The Thesis is widely endorsed, but arguably false and refuted by empirical research. To fix it, we submit, we need a relevance constraint: we accept a simple conditional 'If φ, then ψ' to the extent that (i) the conditional probability p(ψ|φ) is high, provided that (ii) (...) φ is relevant for ψ. How (i) should work is well-understood. It is (ii) that holds the key to improve our understanding of conditionals. Our account has (i) a probabilistic component, using Popper functions; (ii) a relevance component, given via an algebraic structure of topics or subject matters. We present a probabilistic logic for simple indicatives, and argue that its (in)validities are both theoretically desirable and in line with empirical results on how people reason with conditionals.

Tractatus 4.024 inspired the dominant semantics of our time: truth-conditional semantics. Such semantics is focused on possible worlds: the content of p is the set of worlds where p is true. It has become increasingly clear that such an account is, at best, defective: we need an ‘independent factor in meaning, constrained but not determined by truth-conditions’ (Yablo 2014, p. 2), because sentences can be differently true at the same possible worlds. I suggest a missing comment which, had it been (...) included in the Tractatus, would have helped semantics get this right from the start. This is my 4.0241: ‘Knowing what is the case if a sentence is true is knowing its ways of being true’: knowing a sentence’s truth possibilities and what we now call its topic, or subject matter. I show that the famous ‘fundamental thought’ that ‘the “logical constants” do not represent’ (4.0312) can be understood in terms of ways-based views of meaning. Such views also help with puzzling claims like 5.122: ‘If p follows from q, the sense of “p” is contained in the that of “q”’, which are compatible with a conception of entailment combining truth-preservation with the preservation of topicality, or of ways of being true.

Responding to Max Weber’s modern diagnosis of nature, science, and medicine as disenchanted, this article aims to reenvision nature and medicine with a sense of enchantment drawing from the Christian themes of creation, Christology, suffering, and redemption. By reenvisioning nature as enchanted with these theological themes, the vocation of medicine might be revitalized in terms of suffering presence, healing care, and works of mercy toward the neighbor in need.

As groups around the country begin to craft standards for clinical ethics consultations, one focus of that work is the proper procedure for conducting ethics consults. From a recent empirical look into the workings of ethics consult services (ECSs), one worrisome finding is that some ECSs rely on a committee vote when making a recommendation. This article examines the practice of voting and its moral standing as a procedural strategy for arriving at a clinical ethics recommendation. I focus here on (...) the type of clinical ethics conflicts that are most likely to lead an ECS to vote, namely, conflicts involving ethical uncertainty—or, in the Greek, aporia. I argue that in cases of aporia, voting on an ethics conflict is not a morally justifiable procedure. Then on the same grounds that I use to show that voting is ethically problematic, I raise broader concerns about the common practice of making recommendations by other procedures. In contrast to the standard approach of adjudicating between moral claims, I argue that ECSs can best resolve aporetic conflict through the process of clinical ethics mediation. (shrink)

Internationally, there is an on-going dialogue about how to professionalize ethics consultation services . Despite these efforts, one aspect of ECS-competence that has received scant attention is the liability of failing to adequately capture all of the relevant moral considerations in an ethics conflict. This failure carries a high price for the least powerful stakeholders in the dispute. When an ECS does not possess a sophisticated dexterity at translating what stakeholders say in a conflict into ethical concepts or principles, it (...) runs the risk of naming one side's claims as morally legitimate and decrying the other's as merely self-serving. The result of this failure is that one side in a dispute is granted significantly more moral weight and authority than the other. The remedy to this problem is that ECSs learn how to expand the diagnostic moral lens they employ in clinical ethics conflicts. (shrink)

Proficient listening has been viewed as a critical skill in HEC (healthcare ethics consultation) from the inception of the practice, and it is included in the field’s set of core competencies that practitioners need to master to become a certified healthcare ethics consultant (HEC-C). Despite its centrality to the work of HEC, practitioners and trainees receive little or no formal training in the craft of listening, and there are few available resources that ethics consultants and trainees can access to enhance (...) their listening skills. This dearth of training in the skill of listening belies the enormous challenge of listening proficiently. Although many clinical ethics researchers refer to the need for “active listening” in HEC, the term is employed without description or instruction. In this article, I argue that a more helpful depiction of the requisite skill is conveyed by the term “diagnostic listening.” After describing the strategy of diagnostic listening, I introduce a novel technique for honing the listening skills needed for HEC: the ADEPT Model. The ADEPT Model is a tool that can begin to fill the training gap for this important skill. (shrink)

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, but also by (...) their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals.

Timothy Williamson has defended the claim that the semantics of the indicative ‘if’ is given by the material conditional. Putative counterexamples can be handled by better understanding the role played in our assessment of indicatives by a fallible cognitive heuristic, called the Suppositional Procedure. Williamson’s Suppositional Conjecture has it that the Suppositional Procedure is humans’ primary way of prospectively assessing conditionals. This paper raises some doubts on the Suppositional Procedure and Conjecture.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Too Expensive to Treat? Finitude, Tragedy, and the Neonatal ICU by Charles C. CamosyAutumn Alcott RidenourReview of Too Expensive to Treat? Finitude, Tragedy, and the Neonatal ICU CHARLES C. CAMOSY Grand Rapids, MI: Eerdmans, 2010. 208 pp. $18.00In Too Expensive to Treat? Charles Camosy makes an important contribution to bioethics and Christian ethics by making the case for the need to consider social factors when treating imperiled newborns. (...) Arguing for both the full moral status of newborns and Roman Catholic social teaching’s emphasis on the just allocation of resources, Camosy calls the medical community, bioethicists, and [End Page 209] Christian ethicists to account for current practices that disproportionately favor exorbitant costs for imperiled infants over other even more basic medical needs within the US health care system. Written before the adoption of the Affordable Care Act under the Obama administration, Camosy’s argument has only increased in significance given the national need to prioritize resources in view of the government’s expansion of health care coverage.Born within twenty-two to twenty-four weeks of gestation and weighing between 500 and 850 grams, some imperiled infants absorb hundreds of thousands of dollars in short-term care that may extend into millions of dollars given long-term costs (146, 171–93). Recognizing the tragic reality in which “we have virtually unlimited health care needs” coupled with “limited health care resources,” Camosy contends that current Medicaid funds that privilege the NICU (neonatal intensive care unit) should be reevaluated (1–3). In an effort to temper the “autonomous,” patient-driven principle with “justice,” Camosy poses a challenging philosophical, theological, and practical proposal for what he identifies as the “gray area” of the NICU.Maintaining a twofold commitment to human dignity that values the moral worth of the infant, on the one hand, and the common good that privileges a preferential option for the poor, on the other, Camosy develops his argument in four major steps. First, he validates the moral status of newborn infants and rejects social quality of life models that dismiss their intrinsic status as “persons.” Second, he dismisses arguments that emphasize personal dignity at the expense of considering the social quality of life, pointing out that such arguments disregard Catholic social teaching’s emphasis on the link between relational anthropology and human personhood (100). Third, he contends that “weak” social quality of life models that privilege the patient or individual over social considerations do not take seriously either Catholic social teaching’s emphasis on the common good or the potentially overwhelming economic and practical burdens they might place on families and society as a whole. Finally, Camosy presents a constructive proposal for limiting NICU resources that seeks to counter a culture of overtreatment that idolizes technology and is at the mercy of an unrestrained free market (162). Emphasizing the need for a just allocation of resources, he supports withholding and withdrawing life-sustaining treatment in some cases, thus foreseeing the possible death of some infants. Although he does not accept the direct killing of these infants, he does maintain that Catholic social teaching would allow for the withdrawal of life-sustaining treatment based on certain criteria.Camosy raises a host of important considerations relevant to decisions about imperiled infants. Yet a few questions remain. First, from a Christian point of view, does he not fall into a kind of soft utilitarianism, even though he himself desires to avoid the pitfalls of utilitarianism? Second, how might Camosy envision Christian practices that care for “exposed” infants left without life-sustaining treatment? Finally, what about the difficult emotions that accompany [End Page 210] the death of an infant or child? Do certain kinds of grief complicate our rationing choices that appear to pit the old against the young? While perhaps unanswerable, these questions merit further discussion.Autumn Alcott RidenourMerrimack CollegeCopyright © 2015 Society of Christian Ethics... (shrink)

Mediators utilize a wide range of skills in the process of facilitating dialogue and resolving conflicts. Among the most useful techniques for clinical ethics consultants (CECs)—and surely the least discussed—are those employed in acrimonious, hostile conversations between stakeholders. In the context of clinical ethics disputes or other bedside conflicts, good mediation skills can reverse the negative interactions that have prevented the creation of workable treatment plans or ethical consensus. This essay lays out the central framework mediators use in distinguishing positions (...) from interests and describes a set of strategies for managing contentious ethics consultations or working with “difficult” patients, families, or patient-careprovider interactions.

Articulating the public's widespread unease about animal biotechnology has not been easy, and the first attempts have not been able to provide an effective tool for navigating the moral permissibility of this research. Because these moral intuitions have been difficult to cash out, they have been belittled as representing nothing more than fear or confusion. But there are sound philosophical reasons supporting the public's opposition to animal biotechnology and these arguments justify a default position of resistance I call the Presumption (...) of Restraint . The Presumption of Restraint constitutes a justificatory process that sets out the criteria for permitting or rejecting individual biotechnology projects. This Presumption of Restraint can be overridden by compelling arguments that speak to a project's moral and scientific merit. This strategy creates a middle-of-the-road stance that can embrace particular projects, while rejecting others. The Presumption of Restraint can also serve as a model for assessing moral permissibility in other areas of technological innovation. (shrink)

Description logics are a family of knowledge representation formalisms that are descended from semantic networks and frames via the system Kl-one. During the last decade, it has been shown that the important reasoning problems (like subsumption and satisfiability) in a great variety of description logics can be decided using tableau-like algorithms. This is not very surprising since description logics have turned out to be closely related to propositional modal logics and logics of programs (such as propositional dynamic logic), for which (...) tableau procedures have been quite successful.Nevertheless, due to different underlying institutions and applications, most description logics differ significantly from run-of-the-mill modal and program logics. Consequently, the research on tableau algorithms in description logics led to new techniques and results, which are, however, also of interest for modal logicians. In this article, we will focus on three features that play an important rôle in description logics (number restrictions, terminological axioms, and role constructors), and show how they can be taken into account by tableau algorithms.

We need to understand the impossible. Francesco Berto and Mark Jago start by considering what the concepts of meaning, information, knowledge, belief, fiction, conditionality, and counterfactual supposition have in common. They are all concepts which divide the world up more finely than logic does. Logically equivalent sentences may carry different meanings and information and may differ in how they're believed. Fictions can be inconsistent yet meaningful. We can suppose impossible things without collapsing into total incoherence. Yet for the leading philosophical (...) theories of meaning, these phenomena are an unfathomable mystery. To understand these concepts, we need a metaphysical, logical, and conceptual grasp of situations that could not possibly exist: Impossible Worlds. This book discusses the metaphysics of impossible worlds and applies the concept to a range of central topics and open issues in logic, semantics, and philosophy. It considers problems in the logic of knowledge, the meaning of alternative logics, models of imagination and mental simulation, the theory of information, truth in fiction, the meaning of conditional statements, and reasoning about the impossible. In all these cases, impossible worlds have an essential role to play. (shrink)

Behaviourism is the view that preferences, beliefs, and other mental states in social-scientific theories are nothing but constructs re-describing people's behaviour. Mentalism is the view that they capture real phenomena, on a par with the unobservables in science, such as electrons and electromagnetic fields. While behaviourism has gone out of fashion in psychology, it remains influential in economics, especially in ‘revealed preference’ theory. We defend mentalism in economics, construed as a positive science, and show that it fits best scientific practice. (...) We distinguish mentalism from, and reject, the radical neuroeconomic view that behaviour should be explained in terms of brain processes, as distinct from mental states. (shrink)

The Quality Attestation Presidential Task Force's recent proposal for “quality attestation” (QA) of clinical ethics consultants was advanced on the premise that, “[g]iven the importance of clinical ethics consultation, the people doing it should be asked to show that they do it well.” To this end, the task force attempted to develop “a standardized system for proactively assessing the knowledge, skills, and practice of clinical ethicists.” But can this proposed method deliver? If the proposed QA process is flawed, it will (...) label clinical ethicists as qualified to do clinical ethics consultations (CECs) when they are not. The result will be the creation of a new, likely intractable, problem of CEC “false positives:” consultants who have passed QA without actually possessing the requisite knowledge and skills to perform CECs.To avoid the risk of false positives, the QAPTF needs to conduct a rigorous analysis of the skills that the QA process will be positioned to judge and those that are simply beyond the scope of its current metrics. Rather than “attesting” to overall CEC “quality,” QA needs to be precise about the skill inventory it can confirm yet honest about the skills it has no basis to assess. I will argue here that QA has strong prospects for accurately assessing consultants’ competence in ethical analysis but very weak prospects for determining competence in two other skills listed as essential by the QAPTF: value‐neutrality and conflict resolution.

Pets are truly great companions. Some individuals feel that owning a pet can help them prepare for a growing family by giving them a taste of what it would be like to have children. This study also looks into the psychological well-being and life experiences of LGBT fur parents. Employing the Interpretative Phenomenological Analysis, the findings of this study were: (1) With the presence of fur babies, participants had the ease to overcome stressful events, especially the ones that affect their (...) mental health. With these, they have the desire to take care of their fur babies under all circumstances because they see their fur babies as family members. Fur babies are excellent sources of motivation, confidence, and happiness for fur parents. They are treated as family members because they contribute to the mental and emotional aspects of fur parents. Moreover, the majority of respondents valued their pets far more than their actual family members, however, some didn't spend as much time with their relatives and friends. This study comes to the conclusion that a stronger bond with one's dog was also linked to higher anxiety about being unloved and rejected by family members and people surrounding us, which was linked to a heavier impact on one's psychological well-being. In reality, fur parents, especially LGBT parents, offer their fur babies a lot of love and attention compared to other things. (shrink)

Clinicians at quaternary centers see part of their mission as providing hope when others cannot. They tend to see sicker patients with more complex disease processes. Part of this mission is offering longshot treatment modalities that are unlikely to achieve their stated goal, but conceivably could. When patients embark on such a treatment plan, it may fail. Often treatment toward an initial goal continues beyond the point at which such a goal is feasible. We explore the progression of care from (...) longshot to fantasy using two pediatric cases. This progression may be differentiated into four distinct stages of care related to the potential of achieving the initial goals of care. Physicians are often ill prepared for the progression of treatments from a longshot hope to an unfeasible and, therefore, typically unjustified intervention. We present a structured approach to guide clinicians at referral institutions where these situations may be common. The transition of care from “longshot” to “fantasy” is an inherent part of quaternary care for the sickest of patients that has been underexplored. Physicians are often poorly equipped to approach that transition. We advocate this approach to the shift from longshot to fantasy with the belief that such a structured method will have multiple benefits, including: reduced suffering for the patient; decreased emotional burden on patient and family; decreased provider moral distress; increased likelihood of seeking high quality palliative care earlier; and provision of honest and straightforward information to patients and their families.

Feature logics are the logical basis for so-called unification grammars studied in computational linguistics. We investigate the expressivity of feature terms with negation and the functional uncertainty construct needed for the description of long-distance dependencies and obtain the following results: satisfiability of feature terms is undecidable, sort equations can be internalized, consistency of sort equations is decidable if there is at least one atom, and consistency of sort equations is undecidable if there is no atom.

One area of bioethics education with direct impact on the lives of patients, families, and providers is the training of clinical ethics consultants who practice in hospital‐based settings. There is a universal call for increased skills and knowledge among practicing consultants, broad recognition that many are woefully undertrained, and a clear consensus that CECs must avoid an “authoritarian approach” to consultation—an approach, that is, in which the consultant imposes his or her values, ethical priorities, or religious convictions on the stakeholders (...) in an ethics conflict. Yet little work has been done on how to teach CECs not to impose their values in an ethics consultation, or even on the dimensions of this problem. In this essay, I propose a tool for bioethical instruction that targets this question: how can CECs be taught a nonauthoritarian mode of ethical analysis and consultation that can avert the problem of values imposition?

We introduce a “reason-based” framework for explaining and predicting individual choices. It captures the idea that a decision-maker focuses on some but not all properties of the options and chooses an option whose motivationally salient properties he/she most prefers. Reason-based explanations allow us to distinguish between two kinds of context-dependent choice: the motivationally salient properties may (i) vary across choice contexts, and (ii) include not only “intrinsic” properties of the options, but also “context-related” properties. Our framework can accommodate boundedly rational (...) and sophisticatedly rational choice. Since properties can be recombined in new ways, it also offers resources for predicting choices in unobserved contexts. (shrink)

The first introductory textbook on description logics, relevant to computer science, knowledge representation and the semantic web.

Much evidence suggests that semantic characteristics of a message (e.g., the extent to which the message evokes thoughts of spatial or motor properties) and social characteristics of a speaking situation (e.g., whether there is a listener who can see the speaker) both influence how much speakers gesture. However, the Gesture as Simulated Action (GSA) framework (Hostetter & Alibali, ) predicts that these effects should not be independent but should interact such that the effect of visibility is lessened when a message (...) evokes strong thoughts of action. This study tested this claim by comparing the gesture rates produced by speakers as they described 24 nouns that vary in how strongly they evoke thoughts of action. Further, half of the words were described with visibility between speaker and listener blocked. The results demonstrated a significant interaction as predicted by the GSA framework. (shrink)

Franz Brentano (1838-1917) is a key figure in the development of Twentieth Century thought. It was his work that set Husserl on to the road of phenomenology and intentionality, that inspired Meinong's theory of the object which influenced Bertrand Russell, and the entire Polish school of philosophy. ^Descriptive Psychology presents a series of lectures given by Brentano in 1887; they were the culmination of his work, and the clearest statement of his mature thought. It was this later period which (...) proved to be so important in the work of his student, Husserl. This is the first English translation of his work. Benito Muller has added a concise introduction which places Brentano within the history of philosophy and psychology, and locates his influence in contemporary thought. (shrink)

Which rules for aggregating judgments on logically connected propositions are manipulable and which not? In this paper, we introduce a preference-free concept of non-manipulability and contrast it with a preference-theoretic concept of strategy-proofness. We characterize all non-manipulable and all strategy-proof judgment aggregation rules and prove an impossibility theorem similar to the Gibbard--Satterthwaite theorem. We also discuss weaker forms of non-manipulability and strategy-proofness. Comparing two frequently discussed aggregation rules, we show that “conclusion-based voting” is less vulnerable to manipulation than “premise-based voting”, (...) which is strategy-proof only for “reason-oriented” individuals. Surprisingly, for “outcome-oriented” individuals, the two rules are strategically equivalent, generating identical judgments in equilibrium. Our results introduce game-theoretic considerations into judgment aggregation and have implications for debates on deliberative democracy. (shrink)
