מאבק הפרדיגמות מציג פרשנות עקיבה להגות היהודית בימי הביניים על פי תפיסת המדע. הוא משתמש במושג "פרדיגמה" כדי לעקוב אחר ההתפתחות הרעיונית של ההגות היהודית בת הזמן. החיבור פורש לפני הקורא שלוש פרדיגמות: הכלאם, האריסטוטליות (עם או בלי לבושה הנאו-אפלטוני) והניסיוניות (הכוללת תופעות שלא היה להן הסבר בפרדיגמה הקודמת, כמו אסטרולוגיה, מאגיה ואלכימיה). הטענה המרכזית בספר היא שעד לשלהי המאה השתים-עשרה התעמתו שתי הפרדיגמות הראשונות, כלאם ואריסטוטליות, ולאחריה - שתי האחרונות, האריסטוטליות והניסיוניות. החיבור מאיר באור חדש את הגותם של רב (...) סעדיה גאון, ר' יהודה הלוי, רמב"ם ואחרים.

Recent years have seen an increasing interest in the study of continuous-time computational models. However, not so much has been done with respect to setting up a complexity theoretic framework for such models. The present paper intends to go a step into this direction. We consider problems over the real numbers which we try to relate to Lyapunov theory for dynamical systems: The global minimizers of particular energy functions are supposed to give solutions of the problem. The structure of such (...) energy functions leads to the introduction of problem classes U and NU; for the systems we are considering they parallel the classical complexity classes P and NP. We then introduce a notion of reducibility among problems and show existence of complete problems for NU and for PU, a polynomial hierarchy of continuous-time problems.For previous work on the computational capabilities of continuous-time systems see the surveys by Cris Moore [9] and by Pekka Orponen [10]. Our paper presents a step into the direction of creating a general framework for a complexity theory of continuous-time systems as outlined in [10]. It is closely related to work done by A. Ben-Hur, H. Siegelmann, and S. Fishman [12, 11]. (shrink)

Efforts to promote equitable public policy with algorithms appear to be fundamentally constrained by the “impossibility of fairness” (an incompatibility between mathematical definitions of fairness). This technical limitation raises a central question about algorithmic fairness: How can computer scientists and policymakers support equitable policy reforms with algorithms? In this article, I argue that promoting justice with algorithms requires reforming the methodology of algorithmic fairness. First, I diagnose the problems of the current methodology for algorithmic fairness, which I call “formal algorithmic (...) fairness.” Because formal algorithmic fairness restricts analysis to isolated decision-making procedures, it leads to the impossibility of fairness and to models that exacerbate oppression despite appearing “fair.” Second, I draw on theories of substantive equality from law and philosophy to propose an alternative methodology, which I call “substantive algorithmic fairness.” Because substantive algorithmic fairness takes a more expansive scope of analysis, it enables an escape from the impossibility of fairness and provides a rigorous guide for alleviating injustice with algorithms. In sum, substantive algorithmic fairness presents a new direction for algorithmic fairness: away from formal mathematical models of “fair” decision-making and toward substantive evaluations of whether and how algorithms can promote justice in practice.

In many jurisdictions in the United States and elsewhere, the law governing deadly force by police and civilians contains a notable asymmetry. Often civilians but not police are bound by the imminence requirement—that is, a necessary condition for justifying deadly force is reasonable belief that oneself or another innocent person faces imminent threat of grave harm. In U.S. law enforcement, however, there has been some shift toward the imminence requirement, most evident in the use-of-force policy adopted by the Department of (...) Justice in 2022. This article defends that shift and argues that the ethical case for the imminence requirement in policing is stronger than Shannon Brandt Ford suggests in a recent article. Though the imminence requirement’s impacts on policing and public safety require ongoing study, the principle of equality before the law and the Doctrine of Doing and Allowing both provide moral grounds for this requirement, especially given the lack of evidence that the status quo helps protect life.

An overview (about 8,000 words) of act utilitarianism, covering the basic idea of the theory, historical examples, how it differs from rule utilitarianism and motive utilitarianism, supporting arguments, and standard objections. A closing section provides a brief introduction to indirect utilitarianism (i.e., a Hare- or Railton-style view distinguishing between a decision procedure and a criterion of rightness).

Agentialist accounts of self-knowledge seek to do justice to the connection between our identities as rational agents and our capacity to know our own minds. There are two strategies that agentialists have employed in developing their position: substantive and non-substantive. My aim is to explicate and defend one particular example of the non-substantive strategy, namely, that proposed by Tyler Burge. In particular, my concern is to defend Burge's claim that critical reasoning requires a relation of normative directness between reviewing and (...) reviewed perspectives. My defence will involve supplementing Burge's view with a substantive agentialist account of self-knowledge. (shrink)

“Only a small community has concentratedon general intelligence. No one has tried to make a thinking machine... The bottom line is that we really haven’t progressed too far toward a truly intelligent machine. We have collections of dumb specialists in small domains; the true majesty of general intelligence still awaits our attack.... We have got to get back to the deepest questions of AI and general intelligence... ” –MarvinMinsky as interviewed in Hal’s Legacy, edited by David Stork, 2000. Our goal (...) in creating this edited volume has been to?ll an apparent gap in the scienti?c literature, by providing a coherent presentation of a body of contemporary research that, in spite of its integral importance, has hitherto kept a very low pro?le within the scienti?c and intellectual community. This body of work has not been given a name before; in this book we christen it “Arti?cial General Intelligence”. What distinguishes AGI work from run-of-the-mill “arti?cial intelligence” research is that it is explicitly focused on engineering general intelligence in the short term. We have been active researchers in the AGI?eld for many years, and it has been a pleasure to gather together papers from our colleagues working on related ideas from their own perspectives. In the Introduction we give a conceptual overview of the AGI?eld, and also summarize and interrelate the key ideas of the papers in the subsequent chapters. (shrink)

Content-externalism is the view that a subject’s relations to a context can play a role in individuating the content of her mental states. According to social content-externalists, relations to a socio-linguistic context can play a fundamental individuating role. Åsa Wikforss has suggested that ‘social externalism depends on the assumption that individuals have an incomplete grasp of their own concepts’ (Wikforss 2004, p. 287). In this paper, I show that this isn’t so. I develop and defend an argument for social content-externalism (...) which does not depend on this assumption. The argument is animated by strands of thought in the later work of Wittgenstein. In addition to demonstrating that social externalists are not necessarily committed to thinking that a subject can have thoughts involving concepts which she incompletely understands, this argument is important insofar as it: (1) supports a form of content-externalism with extended scope; (2) avoids the controversy surrounding the claim that subjects can think with concepts which they incompletely understand; and (3) situates Wittgenstein’s later work with respect to contemporary debates about content-externalism.

Background Voluntary assisted dying became lawful in Victoria, the first Australian state to permit this practice, in 2019 via the Voluntary Assisted Dying Act 2017 (Vic). While conscientious objection by individual health professionals is protected by the Victorian legislation, objections by institutions are governed by policy. No research has been conducted in Victoria, and very little research conducted internationally, on how institutional objection is experienced by patients seeking assisted dying. Methods 28 semi-structured interviews were conducted with 32 family caregivers and (...) one patient about the experience of 28 patients who sought assisted dying. Participants were interviewed during August-November 2021. Data from the 17 interviews (all with family caregivers) which reported institutional objection were analysed thematically. Results Participants reported institutional objection affecting eligibility assessments, medication access, and taking the medication or having it administered. Institutional objection occurred across health settings and was sometimes communicated obliquely. These objections resulted in delays, transfers, and choices between progressing an assisted dying application and receiving palliative or other care. Participants also reported objections causing adverse emotional experiences and distrust of objecting institutions. Six mediating influences on institutional objections were identified: staff views within objecting institutions; support of external medical practitioners and pharmacists providing assisted dying services; nature of a patient’s illness; progression or state of a patient’s illness; patient’s geographical location; and the capability and assertiveness of a patient and/or caregiver. Conclusions Institutional objection to assisted dying is much-debated yet empirically understudied. This research found that in Victoria, objections were regularly reported by participants and adversely affected access to assisted dying and the wider end-of-life experience for patients and caregivers. This barrier arises in an assisted dying system that is already procedurally challenging, particularly given the limited window patients have to apply. Better regulation may be needed as Victoria’s existing policy approach appears to preference institutional positions over patient’s choice given existing power dynamics. (shrink)

A book chapter (about 9,000 words, plus references) presenting an act-consequentialist approach to the ethics of climate change. It begins with an overview of act consequentialism, including a description of the view’s principle of rightness (an act is right if and only if it maximizes the good) and a conception of the good focusing on the well-being of sentient creatures and rejecting temporal discounting. Objections to act consequentialism, and replies, are also considered. Next, the chapter briefly suggests that act consequentialism (...) could reasonably be regarded as the default moral theory of climate change, in the sense that a broadly act-consequentialist framework often seems implicit in both scholarly and casual discussions of the ethics of climate change. The remainder of the chapter explores three possible responses to the threat of climate change: having fewer children to reduce the number of people emitting greenhouse gases; taxing greenhouse-gas (GHG) emissions (commonly called a “carbon tax”) to discourage GHG-emitting behavior; and reducing poverty to lessen personal, familial, and community vulnerability to the harms of climate change.

Research ethics guidelines grew out of several infamous episodes where research subjects were exploited. There is significant international synchronization of guidelines. However, indigenous groups in New Zealand, Canada and Australia have criticized these guidelines as being inadequate for research involving indigenous people and have developed guidelines from their own cultural perspectives. Whilst traditional research ethics guidelines place a lot of emphasis on informed consent, these indigenous guidelines put much greater emphasis on interdependence and trust. This article argues that traditional guidelines (...) are premised on relationships of equal power, and that often the researcher has more power that is not fully equalized by providing information. Where there is a relationship of unequal power, then focusing on interdependence and trust is more likely to achieve ethical safety. We illustrate this thesis by describing the detail of a research project looking at the use of interpreters, where we video-recorded live consultations and then interviewed the patient, interpreter and doctor. We conclude by suggesting that mainstream research ethics guidelines should pay more attention to the development of a trustworthy relationship between subject and researcher, and that, following the lead from clinical medicine, we should develop a culturally competent ethical framework for research on human subjects.

Agentialism about self-knowledge is the view that key to understanding our capacity for self-knowledge is appreciating the connection between that capacity and our identities as rational agents—as creatures for whom believing, intending, desiring, and so on are manifestations of a capacity to be responsive to reasons. This connection, agentialists maintain, consists in the fact that coming to know our own minds involves an exercise of our rational capacities in the service of answering the relevant first-order question. Agentialists face the task (...) of accounting for the connection between our identities as rational agents and our capacity to know our stored beliefs. It’s plausible that one comes to know that one believes that p by exercising one’s rational capacities in those cases where the belief that p is formed on the basis of present consideration of the reasons for and against p. But what exactly is the relevance of our rational capacities in the case where one has already formed the belief in question? In this paper I provide an answer to this question. That answer involves an appeal to a particular model of memory. According to the model I favor, memory preserves, in addition to the content of one’s beliefs, one’s commitment to their truth.

Since the ages of the Old Testament, the Homeric myths, the tragedies of Sophocles and the ensuing theological speculations of the Christian millennium, the theme of loneliness has dominated and haunted the Western world. In this wide-ranging book, philosopher Ben Lazare Mijuskovic returns us to our rich philosophical past on the nature of consciousness, lived experience, and the pining for a meaningful existence that contemporary social science has displaced in its tendency toward material reduction. Engaging key metaphysical discussions on causality, (...) space, time, subjectivity, the mind body-problem, personal identity, freedom, religion, and transcendence in ancient, scholastic, modern, and contemporary philosophy, he highlights the phenomenology of loneliness that lies at the very core of being human. In challenging psychoanalytic and neuroscientific paradigms, Mijuskovic argues that isolative existence and self-consciousness is not so much of a problem of unconscious conflict or the need for psychopharmacology as it is the loss of a sense of personal intimacy. The issue of the criteria of "personal identity" in relation to loneliness has long engaged and consumed the interest of theologians, ethicists, philosophers, novelists and psychologists. This book will be of great interests to academics and students of the humanities, and all those with an interest in the philosophy of loneliness.. (shrink)

We developed this study to examine the issue of parental refusal of treatment, looking at the issue through a cultural competence lens. Recent cases in Canada where courts have declined applications by clinicians for court orders to overrule parental refusal of treatment highlight the dispute in this area. This study analyses the 16 cases of a larger group of 24 cases that were selected by a literature review where cultural or religious beliefs or ethnic identity was described as important reasons (...) behind the refusal. The most significant finding was that nearly all of the cases cited unacceptable side effects as the main reason for declining treatment. We then analysed the detail of the cases and concluded that in the first instance a skilled clinical approach to develop an agreed management plan is by far the best approach. In the event that agreement cannot be reached we recommend engaging a mediator to help the clinician and parents/child to find an agreeable way forward. We argue that the option of se... (shrink)

Pickeringet al’s paper argues that the capacity of the decision-maker is the sole consideration in whether a decision should stand, and that the risk of the decision should not be considered. This argument ignores the existence of the player who is of the view that a decision is not wise. This paper argues that patient autonomy is not the sole determinant of whether a person is able to make an unwise decision, particularly in healthcare where there are always others affected (...) by the patient decision. Rather than asserting that patients have an unfettered autonomous choice on clinical decisions this paper argues that these decisions should be looked at through the lens of quality in health care that has proposed four parameters to be balanced; the patient experience, wise use of resources, the effect on public health and the clinician experience.

This paper discusses the Saudi Arabian case by Abdallah Adlan and Henk ten Have, published in a 2012 issue of the Journal of Bioethical Inquiry, regarding a congenitally disabled child enrolled in a research project examining the genetics of her condition. During the course of the study, her father was found not to be genetically related, and the case discussed the dilemma between disclosing to the family all findings as promised in consent documents or withholding paternity information because of the (...) likely severe social repercussions. Using Adlan and ten Have’s example, this paper proposes a framework to consider cases outside of the conventional bioethics frame of reference, splitting the bioethical task into three elements: understanding the problem from the patient’s and the clinician’s perspective and then engaging in dialogue to decide what to do next. The process of dialogue between affected parties is vital. Presuming that there is a common morality undermines the effectiveness of the dialogue needed to find a resolution. (shrink)

In her ‘Primitive Normativity and Scepticism about Rules’ (2011b), Hannah Ginsborg proposes a novel solution to Kripke’s sceptical challenge to factualists about meaning (those who think that there is some fact about what you mean or meant by your utterances). According to Ginsborg, the fact in virtue of which you mean, say, addition by ‘plus’ is the fact that ‘you are disposed to respond to a query about (say) “68 plus 57” with “125,” where, in responding in that way, you (...) take that response to be primitively appropriate in light of your previous uses of “plus”’ (Ginsborg 2011b, 244). Ginsborg’s account is at its most compelling when considering what we might call unsophisticated cases of meaning, cases in which a subject means something by their words without their being in a position to identify the relevant rule or provide any sort of justification for their using the term as they do. In this paper, I raise doubts about whether Ginsborg’s account is extendable to sophisticated cases of meaning. Reflection on those cases which generate the doubts brings it into question whether the dispositions that Ginsborg identifies are necessary and jointly sufficient for one’s meaning that p even in unsophisticated cases.

Interactive robots are used increasingly not only in entertainment and service robotics, but also in rehabilitation, therapy and education. The work presented in this paper is part of the Aurora project, rooted in assistive technology and robot-human interaction research. Our primary aim is to study if robots can potentially be used as therapeutically or educationally useful ‘toys’. In this paper we outline the aims of the project that this study belongs to, as well as the specific qualitative contextual perspective that (...) is being used. We then provide an in-depth evaluation, in part using Conversation Analysis, of segments of trials where three children with autism interacted with a robot as well as an adult. We focus our analysis primarily on joint attention which plays a fundamental role in human development and social understanding. Joint attention skills of children with autism have been studied extensively in autism research and therefore this behaviour provides a relevant focus for our study. In the setting used, joint attention emerges from natural and spontaneous interactions between a child and an adult. We present the data in the form of transcripts and photo stills. The examples were selected from extensive video footage for illustrative purposes, i.e. demonstrating how children with autism can respond to the changing behaviour of their co-participant, i.e. the experimenter. Furthermore, our data shows that the robot provides a salient object, or mediator for joint attention. The paper concludes with a discussion of implications of this work in the context of further studies with robots and children with autism within the Aurora project, as well as the potential contribution of robots to research into the nature of autism.

This article presents a novel set of ten play scenarios for robot-assisted play for children with special needs. This set of scenarios is one of the key outcomes of the IROMEC project that investigated how robotic toys can become social mediators, encouraging children with special needs to discover a range of play styles, from solitary to collaborative play. The target user groups in the project were children with Mild Mental Retardation,1 children with Severe Motor Impairment and children with Autism. The (...) play scenarios were developed against specific educational and therapeutic objectives that were discussed with panels of experts in various countries, during several user panel meetings for each of the above mentioned target user groups. These objectives were classified with reference to the ICF-CY, the International Classification of Functioning – version for Children and Youth. The article presents a detailed description of the play scenarios, each with its relevant educational and therapeutic objectives in five key developmental areas. While the play scenarios described in this paper originally were developed for and tested with the above user groups and with the IROMEC robot, the play scenarios can potentially be applied to other user groups and to a wide range of other applications involving human-robot interaction using different robotic toys. Keywords: human-robot interaction; assistive technology; play scenarios; autism; mild mental retardation; sever motor impairment; assisted play. (shrink)

Chalmers’ meta-problem of consciousness is the problem of explaining “problem reports”; i.e. reports to the effect that phenomenal consciousness has the various features that give rise to the hard problem. Chalmers (Journal of Consciousness Studies 25: 6–61, 2018, 8) suggests that solving the meta-problem will likely “shed significant light on the hard problem.” Against this, I argue that work on the meta-problem will likely fail to make the hard problem any easier. For each of the main stances on the hard (...) problem can provide an account of problem reports, and we have no way of deciding which of these accounts gives the correct explanation of an individual’s problem reports without presupposing a stance on the hard problem. We thus cannot determine which of the available solutions to the meta-problem is correct without having already solved the hard problem. (shrink)

Oxford philosopher Nick Bostrom; in his recent and celebrated book Superintelligence; argues that advanced AI poses a potentially major existential risk to humanity; and that advanced AI development should be heavily regulated and perhaps even restricted to a small set of government-approved researchers. Bostrom’s ideas and arguments are reviewed and explored in detail; and compared with the thinking of three other current thinkers on the nature and implications of AI: Eliezer Yudkowsky of the Machine Intelligence Research Institute ; and David (...) Weinbaum and Viktoras Veitas of the Global Brain Institute. Relevant portions of Yudkowsky’s book Rationality: From AI to Zombies are briefly reviewed; and it is found that nearly all the core ideas of Bostrom’s work appeared previously or concurrently in Yudkowsky’s thinking. However; Yudkowsky often presents these shared ideas in a more plain-spoken and extreme form; making clearer the essence of what is being claimed. For instance; the elitist strain of thinking that one sees in the background in Bostrom is plainly and openly articulated in Yudkowsky; with many of the same practical conclusions. Bostrom and Yudkowsky view intelligent systems through the lens of reinforcement learning – they view them as “reward-maximizers” and worry about what happens when a very powerful and intelligent reward-maximizer is paired with a goal system that gives rewards for achieving foolish goals like tiling the universe with paperclips. Weinbaum and Veitas’s recent paper “Open-Ended Intelligence” presents a starkly alternative perspective on intelligence; viewing it as centered not on reward maximization; but rather on complex self-organization and self-transcending development that occurs in close coupling with a complex environment that is also ongoingly self-organizing; in only partially knowable ways. It is concluded that Bostrom and Yudkowsky’s arguments for existential risk have some logical foundation; but are often presented in an exaggerated way. For instance; formal arguments whose implication is that the “worst case scenarios” for advanced AI development are extremely dire; are often informally discussed as if they demonstrated the likelihood; rather than just the possibility; of highly negative outcomes. And potential dangers of reward-maximizing AI are taken as problems with AI in general; rather than just as problems of the reward-maximization paradigm as an approach to building superintelligence. If one views past; current; and future intelligence as “open-ended;” in the vernacular of Weaver and Veitas; the potential dangers no longer appear to loom so large; and one sees a future that is wide-open; complex and uncertain; just as it has always been.

As dominant liberal conceptions of the relationship between rights and freedom maintain, freedom is a property of the individual human subject and rights are a mechanism for protecting that freedom—whether it be the freedom to speak, to associate, to practise a certain religion or cultural way of life, and so forth. Rights according to these kinds of accounts are protective of a certain zone of permitted or valorised conduct and they function either as, for example, a ‘side-constraint’ on the actions (...) of others or as a ‘trump’ over governmental or community goals. In such accounts, of course, the emphasis is placed upon the forms of power against which rights protect the individual, whether that be the trespasses of others or the overweening attentions of the state. Such accounts famously do not themselves take much account of the multiple ways in which rights also function as forms of power, often delimiting the courses of action that a putative rights-holder can take and affecting the manner of its exercise, indeed often in the very name of freedom itself. Of course, there is a sizeable critical literature which does address itself to these kinds of question, most notably from the radical traditions of Marxism and critical legal theory, which see rights in terms of the relations of production, consumption and exploitation that they establish between legal subjects. For various reasons, Foucault has not figured as prominently in critical discussions of rights. Here I do not propose to enter into debates surrounding Foucault’s engagement with, or failure to engage with, law as an object of study, nor with the emergent literature on Foucault’s deployments of rights, indeed even of human rights. Rather, what I want to do in this paper is to articulate and defend the view that through a reading of Foucault’s work, both on rights and on power relations more broadly, we can discern an understanding of the political ambivalence of rights. For Foucault (and for some of the post-Foucaultian scholars whose work I shall address, below), rights are both political tools for the contestation and alteration of mechanisms of power and simultaneously mechanisms of inscription, both disciplinary and governmental, which work to conduct those who rely upon them. Far from being an unproblematic tool for the protection of the subject’s freedom, rights emerge in this account as conflicted and ambivalent mechanisms. In the first part of this paper I develop a Foucaultian account of rights along these lines and then hope to illustrate it by reference to several examples, from the constitution of gender and cultural identity via rights to the figure of the refugee, whilst in the final part of the paper I make a return to the idea of freedom in Foucault’s work and link the view of rights developed herein to a certain conception of freedom in his work.

Abstract:Recently the scope of protections afforded those healthcare professionals and institutions that refuse to provide certain interventions on the grounds of conscience have expanded, in some instances insulating providers (institutional and individual) from any liability or sanction for harms that patients experience as a result. With the exponential increase in the penetration of Catholic-affiliated healthcare across the country, physicians and nurses who are not practicing Catholics are nevertheless required to execute documents pledging to conform their patient care to the Ethical (...) and Religious Directives for Health Care Services as a condition of employment or medical staff privileges. In some instances, doing so may result in patient morbidity or mortality or violate professional standards for respecting advance directives or surrogate decisionmaking. This article challenges the ethical propriety of such institutional mandates and argues that legal protections for conscientious refusal must provide redress for patients who are harmed by care that falls below the prevailing clinical standards.

This article studies the impact of a robot’s appearance on interactions involving four children with autism. This work is part of the Aurora project with the overall aim to support interaction skills in children with autism, using robots as ‘interactive toys’ that can encourage and mediate interactions. We follow an approach commonly adopted in assistive robotics and work with a small group of children with autism. This article investigates which robot appearances are suitable to encourage interactions between a robot and (...) children with autism. The children’s levels of interaction with and response to different appearances of two types of robots are compared: a small humanoid doll, and a life-sized ‘Theatrical Robot’. The small humanoid robot appeared either as a human-like ‘pretty doll’ or as a ‘robot’ with plain features. The Theatrical Robot was presented either as an ordinary human, or with plain clothing and a featureless, masked face. The results of these trials clearly indicate the children’s preference in their initial response for interaction with a plain, featureless robot over the interaction with a human-like robot. In the case of the life-size Theatrical Robot, the response of children towards the plain/robotic robot was notably more social and pro-active. Implications of these results for our work on using robots as assistive technology for children with autism and their possible use in autism research are discussed. (shrink)

Many people believe that if we could produce meat without animal suffering—say, in ‘humane’ or ‘happy’ farms, or by growing it in a lab from biopsied cells—there would be no moral problem with doing so. This chapter argues otherwise. There is something morally ‘off’ with eating the flesh of sentient beings however it is produced. It is ‘off’ because anyone who truly understands the intimate relationship that an animal’s body stands in to all the value and disvalue in their lives (...) would not want to eat flesh. The chapter concludes by arguing that, as a society, we should not switch over to ‘happy’ or lab-grown meat. Instead, it is imperative that we pursue a public reckoning on our treatment of animals in factory farms, not only for the sake of animals, but for the sake of humanity itself. (shrink)

The idea that our recognition of others’ mental states is beset, not only by contingent but constitutional uncertainty is one to which Wittgenstein returns throughout his later work. And yet it remains an underexplored component of that work. The primary aim of this paper is to better understand what Wittgenstein means when he describes the mental as constitutively uncertain, and his conception of the kind of knowledge of others' mental lives consistent with it. The secondary aim is to connect Wittgenstein’s (...) discussion of the constitutive uncertainty of the mental with two further components of his later thought—specifically, his remarks on aspect perception and on the pattern-like nature of the emotions.

A novel theory of reflective consciousness, will and self is presented, based on modeling each of these entities using self-referential mathematical structures called hypersets. Pattern theory is used to argue that these exotic mathematical structures may meaningfully be considered as parts of the minds of physical systems, even finite computational systems. The hyperset models presented are hypothesized to occur as patterns within the "moving bubble of attention" of the human brain and any roughly human-mind-like AI system. These ideas appear to (...) be compatible with both panpsychist and materialist views of consciousness, and probably other views as well. Their relationship with the CogPrime AI design and its implementation in the OpenCog software framework is elucidated in detail. (shrink)

The concept of person is integral to bioethical discourse because persons are the proper subject of the moral domain. Nevertheless, the concept of person has played no role in the prevailing formulation of human death because of a purported lack of consensus concerning the essential attributes of a person. Beginning with John Locke's fundamental proposition that person is a ‘forensic term’, I argue that in Western society we do have a consensus on at least one necessary condition for personhood, and (...) that is the capacity for conscious experience. When we consider the whole brain formulation of death, and the most prominent defense of it by the President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research, we can readily identify the flaws that grow out of the failure to define human death as the permanent loss of the capacity for conscious experience. Most fundamental among these flaws is a definition of human death that reduces persons to the capacity of the brain to regulate purely physiological functioning. Such a formulation would, in theory, apply to any member of the animal kingdom. I suggest that an appropriate concept of death should capture what it is about a particular living being that is so essential to it that the permanent loss of that thing constitutes death. What is essential to being a human being is living the life of a person, which derives from the capacity for conscious experience. (shrink)

Abstract:The specialty of psychiatry has a long-standing, virtually monolithic view that a desire to die, even a desire for a hastened death among the terminally ill, is a manifestation of mental illness. Recently, psychiatry has made significant inroads into hospice and palliative care, and in doing so brings with it the conviction that dying patients who seek to end their suffering by asserting control over the time and manner of their inevitable death should be provided with psychotherapeutic measures rather than (...) having their expressed wishes respected as though their desire for an earlier death were the rational choice of someone with decisional capacity. This article reviews and critiques this approach from the perspective of recent clinical data indicating that patients who secure and utilize a lethal prescription are generally exercising an autonomous choice unencumbered by clinical depression or other forms of incapacitating mental illness.

What will be the next huge leap in humanity's progress? We cannot know for sure, but I am reasonably confident that it will involve the radical extension of technology into the domain of thought. Ray Kurzweil (2000, 2005) has eloquently summarized the arguments in favor of this position.

The 70th anniversary of Aldo Leopold’s A Sand County Almanac (1949) approaches. For philosophers—environmental ethicists in particular—this text has been highly influential, especially the ‘Land Ethic’ essay contained therein. Given philosophers’ acumen for identifying and critiquing arguments, one might reasonably think a firm grasp of Leopold’s ideas to have emerged from such attention. I argue that this is not the case. Specifically, Leopold’s main interpreter and systematiser, philosopher J. Baird Callicott, has shoehorned Aldo Leopold’s ideas into differing monistic moral theories (...) that ill-serve a proper understanding. Against Callicott, my paper argues that Aldo Leopold embraces a robust moral pluralism, one that goes beyond mere pragmatics, and he does so while seeking a consistency maximisation of values. A new, improved understanding of Leopold’s ideas thus emerges. (shrink)

We study a logic for reasoning about agents that pass messages according to a protocol. Protocols are specified extensionally, as sets of sequences of ?legal? actions assigned to each state in a Kripke model. Message-passing events that are licensed by the protocol are modeled as updates in the style of dynamic epistemic logic. We also consider changes to the protocol by introducing message-encoding modalities, corresponding to communications actions that lead to protocol extensions. While in our general framework, messages are arbitrary (...) objects, we also consider the case that the messages that are passed are sentences of the object language itself. We present complete calculi for our logics and clarify the relationship of our proposal to earlier work on public announcement logic. (shrink)

William Lane Craig modified Bertrand Russell’s Tristram Shandy example in order to derive an absurdity that would demonstrate the finitude of the past.

This article traces the development of a particular line of argument that arose from Craig’s Tristram Shandy example before advancing an argument (...) of its own that attempts to fill in the relevant gaps so as to yield a new argument for the finitude of the past.

Setting aside all exclusion-style worries about the redundancy of postulating additional, non-physical mental causes for effects that can already be explained in purely physical terms, dualists who treat mental properties as supervening on physical properties still face a further problem: in cases of mental-to-mental causation, they cannot avoid positing an implausibly coincidental coordination in the timing of the distinct causal processes terminating, respectively, in the mental effect and its physical base. I argue that this problem arises regardless of whether one (...) treats the mental cause as causing both the mental effect and its physical base, or whether one treats the latter as having instead been caused by some physical state, and that the problem also does not depend on which theory of causation one adopts. A third option of treating the mental cause and its physical base as producing the mental effect and its physical base by a single causal process that they both contribute to is found to come up short as well.
