This chapter provides an introduction to higher-order metaphysics as well as to the contributions to this volume. We discuss five topics, corresponding to the five parts of this volume, and summarize the contributions to each part. First, we motivate the usefulness of higher-order quantification in metaphysics using a number of examples, and discuss the question of how such quantifiers should be interpreted. We provide a brief introduction to the most common forms of higher-order logics used in metaphysics, and indicate a (...) number of questions which can be raised in such systems using logical vocabulary alone. Using a further example, we return to applications of higher-order logics in metaphysics. We also mention key developments in the history of higher-order logic as it pertains to metaphysics. Finally, we mention certain arguments which have been raised against the use of higher-order logic, and some ways of responding to them. (shrink)

This volume explores the use of higher-order logics in metaphysics. Seventeen original essays trace the development of higher-order metaphysics, discuss different ways in which higher-order languages and logics may be used, and consider their application to various central topics of metaphysics.

What is man? “The feather of an angel was brought and tied to a donkey's tail that the donkey perhaps might turn into an angel”.Thus writes the greatest of all Persian-writing mystical poets of Islam, Maulânâ Jalâladdân Rûmî (1207-1273) in his conversations, Fîhi mâ fîhi, when pointing to the mystery of man's existence : man is able to attain a rank superior to that of the angels (who have no free will and are eternally good) provided he develops his God-given (...) faculties of reason and love; but he can sink lower than a beast if he neglects his spiritual powers and falls a prey to sensual pleasures and crimes owing to the misuse of his rational faculties.

Donald C. Ainslie's Hume's True Scepticism is a wonderful book—clearly written and forcefully argued—and was deservedly honored with Journal of the History of Philosophy's Book Prize for 2016. The focus of the book is part four of the first Book of Hume's Treatise, "Of the sceptical and other systems of philosophy." Ainslie develops an interpretation that takes seriously Hume's psychological claims, using them to solve puzzles in Hume scholarship, including the extent of Hume's scepticism, the nature of his sceptical crisis, (...) and the basis for his second thoughts on personal identity.I would encourage Ainslie to go further in tracing Hume's psychological explanations. In what follows, I will... (shrink)

A large body of information and opinion related to COVID-19 is being shared via social media platforms. Recent reports have raised concerns about the reliability and verifiability of said information being disseminated and the way systems, processes and design of the platforms facilitates such spread. This, alongside other areas of concern, has resulted in several social media platforms taking steps towards tackling the spread of mis- and dis-information. Here we discuss approaches to online public health messaging from a range of (...) sources during COVID-19, with a focus on official and non-official sources in the United Kingdom. We highlight issues for ongoing public health decisions, and the potential impact for the future course of the pandemic. (shrink)

Die Behandlung von einwilligungsunfähigen psychisch kranken Menschen mit neuen Therapiemethoden ist insbesondere im Kontext des „individuellen Heilversuchs“, der als Anwendung wenig erprobter Therapieansätze im Rahmen von „ultima ratio“-Entscheidungen charakterisiert ist, mit ethischen Abwägungsproblemen verbunden. Diese bestehen aufgrund von Einschränkungen in der Handlungs- und Entscheidungsautonomie der betroffenen Patienten und, aufgrund eigen- oder fremdgefährdender Symptome der psychischen Krankheit selbst, insbesondere in der praktischen Umsetzung ethisch akzeptierter Modelle stellvertretender Entscheidung sowie in der Wahl des Bezugspunkts der Nutzen-Risiko-Analyse des intendierten Therapieverfahrens. Der Artikel untersucht (...) den ethischen Konflikt zwischen gerechtfertigter Hilfeleistung und Instrumentalisierungsrisiko psychisch kranker Menschen zu Fremdzwecken am historischen Beispiel der „Rindenexcisionen“ des Psychiaters Gottlieb Burckhardt (1836–1907). Als Lösungsmöglichkeit dieses ethischen Konflikts wird das „Konzept des kontrollierten individuellen Heilversuchs“ diskutiert. (shrink)

Recent studies of scientific interaction based on agent-based models suggest that a crucial factor conducive to efficient inquiry is what Zollman has dubbed ‘transient diversity’. It signifies a process in which a community engages in parallel exploration of rivaling theories lasting sufficiently long for the community to identify the best theory and to converge on it. But what exactly generates transient diversity? And is transient diversity a decisive factor when it comes to the efficiency of inquiry? In this paper we (...) examine the impact of different conditions on the efficiency of inquiry, as well as the relation between diversity and efficiency. This includes certain diversity-generating mechanisms previously proposed in the literature, as well as some factors that have so far been neglected. This study is obtained via an argumentation-based ABM. Our results suggest that cautious decision-making does not always have a significant impact on the efficiency of inquiry while different evaluations underlying theory-choice and different social networks do. Moreover, we find a correlation between diversity and a successful performance of agents only under specific conditions, which indicates that transient diversity is sometimes not the primary factor responsible for efficiency. Altogether, when comparing our results to those obtained by structurally different ABMs based on Zollman’s work, the impact of specific factors on efficiency of inquiry, as well as the role of transient diversity in achieving efficiency, appear to be highly dependent on the underlying model.

Controversy swept the U.K. in January of 2000 over public disclosure of the fact that a Scottish surgeon named Robert Smith had amputated the limbs of two able-bodied individuals who reportedly suffered from a condition known as apotemnophilia. The patients, both of whom had sought and consented to the surgery, claimed they had desperately desired for years to live as amputees and had been unable, despite considerable efforts, to reconcile themselves psychologically to living with the bodies with which they were (...) born. Both surgeries were successful, and both patients, who had undergone psychiatric evaluation prior to the amputations, subsequently reported having no regrets. In the wake of a wave of sensationalistic stories in the media, the hospital at which the surgeries had been performed, the Falkirk and District Royal Infirmary, banned any future surgeries of the kind. Outraged local politicians promptly announced their intention to pass laws banning the procedure outright. One member of Scottish Parliament declared the surgery obscene and asserted that the whole thing is repugnant and legislation needs to be brought in now to outlaw this. (shrink)

This paper presents a challenge to conciliationist views of disagreement. I argue that conciliationists cannot satisfactorily explain why we need not revise our beliefs in response to certain moral disagreements. Conciliationists can attempt to meet this challenge in one of two ways. First, they can individuate disputes narrowly. This allows them to argue that we have dispute-independent reason to distrust our opponents’ moral judgment. This approach threatens to license objectionable dogmatism. It also inappropriately gives deep epistemic significance to superficial questions (...) about how to think about the subject matter of a dispute. Second, conciliationists can individuate disputes widely. This allows them to argue that we lack dispute-independent reason to trust our opponents’ moral judgment. But such arguments fail; our background of generally shared moral beliefs gives us good reason to trust the moral judgment of our opponents, even after we set quite a bit of our reasoning aside. On either approach, then, conciliationists should acknowledge that we have dispute-independent reason to trust the judgment of those who reject our moral beliefs. Given a conciliationist view of disagreement’s epistemic role, this has the unattractive result that we are epistemically required to revise some of our most intuitively secure moral beliefs.

A well‐known typological observation is the dominance of subject‐initial word orders, SOV and SVO, across the world's languages. Recent findings from gestural language creation paradigms offer possible explanations for the prevalence of SOV. When asked to gesture transitive events with an animate agent and inanimate patient, gesturers tend to produce SOV order, regardless of their native language biases. Interestingly, when the patient is animate, gesturers shift away from SOV to use of other orders, like SVO and OSV. Two competing hypotheses (...) have been proposed for this switch: the noisy channel account (Gibson et al., 2013) and the role conflict account (Hall, Mayberry, & Ferreira, 2013). We set out to distinguish between these two hypotheses, disentangling event reversibility and patient animacy, by looking at gestural sequences for events with two inanimate participants (inanimate‐inanimate, reversible). We replicated the previous findings of a preference for SOV order when describing animate‐inanimate, irreversible events as well as a decrease in the use of SOV when presented with animate‐animate, reversible events. Accompanying the drop in SOV, in a novel condition we observed an increase in the use of SVO and OSV orders when describing events involving two animate entities. In sum, we find that the observed avoidance of SOV order in gestural language creation paradigms when the event includes an animate agent and patient is driven by the animacy of the participants rather than the reversibility of the event. We suggest that findings from gestural creation paradigms are not automatically linkable to spoken language typology. (shrink)

Much of the time, human beings seem to rely on habits. Habits are learned behaviours directly elicited by context cues, and insensitive to short-term changes in goals: therefore they are sometimes irrational. But even where habitual responses are rational, it can seem as if they are nevertheless not done for reasons. For, on a common understanding of habitual behaviour, agents’ intentions do not play any role in the coming about of such responses. This paper discusses under what conditions we can (...) say that habitual responses are, after all, done for reasons. We show how the idea that habitual behaviour cannot be understood as ‘acting for reasons’ stems from a widely but often implicitly held theoretical framework: the causal theory of action. We then propose an alternative, Anscombean understanding of intentional action, which can account for habitual responses being done for reasons. (shrink)

Die Sprachlichkeit des Glaubens ist von Anfang an zentrales Thema protestantischer Theologie. Der Glaube, als Vertrauen auf das biblisch bezeugte und lebendig gepredigte Evangelium, lebt in der Sprache, weil er aus dem Horen kommt: Er vollzieht sich im Modus des Verstehens. Seit jeher sind daher theologische Hermeneutik und Homiletik Orte, an denen die Sprachlichkeit des Glaubens reflektiert wird. Diese Reflexion setzen die Beitrage des vorliegenden Bandes in je unterschiedlicher Facherperspektive fort.

We may be at the brink of a Kuhnian paradigm shift when it comes to the categorical classification system of mental disorders. Reviewing more than 30 years of critical literature on the categorical classification of personality disorders, Kueger, Hopwood, Wright, and Markon conclude that the Diagnostic and Statistical Manual of Mental Disorders is "fundamentally broken". Just before, the director of the National Institute of Mental Health declared that the institute will no longer support research that is based on DSM categories.The (...) critique on the categorical system of mental disorders consists of several arguments that are briefly mentioned as they have been...

Even the simplest narratives combine multiple strands of information, integrating different characters and their actions by expressing multiple perspectives of events. We examined the emergence of referential shift devices, which indicate changes among these perspectives, in Nicaraguan Sign Language (NSL). Sign languages, like spoken languages, mark referential shift grammatically with a shift in deictic perspective. In addition, sign languages can mark the shift with a point or a movement of the body to a specified spatial location in the three-dimensional space (...) in front of the signer, capitalizing on the spatial affordances of the manual modality. We asked whether the use of space to mark referential shift emerges early in a new sign language by comparing the first two age cohorts of deaf signers of NSL. Eight first-cohort signers and ten second-cohort signers watched video vignettes and described them in NSL. Narratives were coded for lexical (use of words) and spatial (use of signing space) devices. Although the cohorts did not differ significantly in the number of perspectives represented, second-cohort signers used referential shift devices to explicitly mark a shift in perspective in more of their narratives. Furthermore, while there was no significant difference between cohorts in the use of non-spatial, lexical devices, there was a difference in spatial devices, with second-cohort signers using them in significantly more of their narratives. This suggests that spatial devices have only recently increased as systematic markers of referential shift. Spatial referential shift devices may have emerged more slowly because they depend on the establishment of fundamental spatial conventions in the language. While the modality of sign languages can ultimately engender the syntactic use of three-dimensional space, we propose that a language must first develop systematic spatial distinctions before harnessing space for grammatical functions.

In part 1 of Enquiry 12, Hume presents a skeptical argument against belief in external existence. The argument involves a perceptual relativity argument that seems to conclude straightaway the double existence of objects and perceptions, where objects cause and resemble perceptions. In Treatise 1.4.2, Hume claimed that the belief in double existence arises from imaginative invention, not reasoning about perceptual relativity. I dissolve this tension by distinguishing the effects of natural instinct and showing that some ofthese effects supplement the Enquiry’s (...) perceptual relativity argument. The Enquiry’s skeptical argument thus reveals the fundamental involvement of natural instinct in any belief in external existence. (shrink)
