There is a basic distinction, in the realm of spatial boundaries, between bona fide boundaries on the one hand, and fiat boundaries on the other. The former are just the physical boundaries of old. The latter are exemplified especially by boundaries induced through human demarcation, for example in the geographic domain. The classical problems connected with the notions of adjacency, contact, separation and division can be resolved in an intuitive way by recognizing this two-sorted ontology of boundaries. Bona fide boundaries (...) yield a notion of contact that is effectively modeled by classical topology; the analogue of contact involving fiat boundaries calls, however, for a different account, based on the intuition that fiat boundaries do not support the open/closed distinction on which classical topology is based. In the presence of this two-sorted ontology it then transpires that mereotopology—topology erected on a mereological basis—is more than a trivial formal variant of classical point-set topology.

The concept of niche (setting, context, habitat, environment) has been little studied by ontologists, in spite of its wide application in a variety of disciplines from evolutionary biology to economics. What follows is a first formal theory of this concept, a theory of the relations between objects and their niches. The theory builds upon existing work on mereology, topology, and the theory of spatial location as tools of formal ontology. It will be illustrated above all by means of simple biological (...) examples, but the concept of niche should be understood as being, like concepts such as part, boundary, and location, a structural concept that is applicable in principle to a wide range of different domains.

There are conflicting intuitions concerning the status of a boundary separating two adjacent entities (or two parts of the same entity). The boundary cannot belong to both things, for adjacency excludes overlap; and it cannot belong to neither, for nothing lies between two adjacent things. Yet how can the dilemma be avoided without assigning the boundary to one thing or the other at random? Some philosophers regard this as a reductio of the very notion of a boundary, which should accordingly (...) be treated a mere façon de parler. In this paper I resist this temptation and examine some ways of taking the puzzle at face value within a realist perspective—treating boundaries as ontologically on a par with (albeit parasitic upon) extended parts.

Neutral monism is a position in metaphysics defended by Mach, James, and Russell in the early twentieth century. It holds that minds and physical objects are essentially two different orderings of the same underlying neutral elements of nature. This paper sets out some of the central concepts, theses and the historical background of ideas that inform this doctrine of elements. The discussion begins with the classic neutral monism of Mach, James, and Russell in the first part of the paper, then (...) considers recent neo-Russellian versions in the second half. The chances for a revival of neutral monism are probably slight; its key ideas and starting points lie far from those in contemporary philosophy of mind. A better route might be through the philosophy of science and a deeper understanding of causation. (shrink)

Many believe that the rational evaluation of actions depends on the rational evaluation of even basic desires. Hume, though, viewed desires as "original existences" which cannot be contrary to either truth or reason. Contemporary critics of Hume, including Norman, Brandt and Parfit, have sought a basis for the rational evaluation of desires that would deny some basic desires reason-giving force. I side with Hume against these modern critics. Hume's concept of rational evaluation is admittedly too narrow; even basic desires are, (...) despite their nonrepresentational nature, subject to rational evaluation. But this evaluation is not relevant to their tendency to generate reasons for action, and does not undermine the spirit of the Humean view of rational action. (shrink)

Are there any bona fide boundaries, i.e., boundaries that carve at the joints? Or is any boundary —hence any object—the result of a fiat articulation reflecting our cognitive biases and our so-cial practices and conventions? Does the choice between these two options amount to a choice between realism and wholesome relativism?

Neo-Humean instrumentalist theories of reasons for acting have been presented with a dilemma: either they are normatively trivial and, hence, inadequate as a normative theory or they covertly commit themselves to a noninstrumentalist normative principle. The claimed result is that no purely instrumentalist theory of reasons for acting can be normatively adequate. This dilemma dissolves when we understand what question neo-Humean instrumentalists are addressing. The dilemma presupposes that neo-Humeans are attempting to address the question of how to act, 'simpliciter'. Instead, (...) they are evaluating actions from the agent's normative perspective.

Cognitive agents, whether human or computer, that engage in natural-language discourse and that have beliefs about the beliefs of other cognitive agents must be able to represent objects the way they believe them to be and the way they believe others believe them to be. They must be able to represent other cognitive agents both as objects of beliefs and as agents of beliefs. They must be able to represent their own beliefs, and they must be able to represent beliefs (...) as objects of beliefs. These requirements raise questions about the number of tokens of the belief representation language needed to represent believers and propositions in their normal roles and in their roles as objects of beliefs. In this paper, we explicate the relations among nodes, mental tokens, concepts, actual objects, concepts in the belief spaces of an agent and the agent's model of other agents, concepts of other cognitive agents, and propositions. We extend, deepen, and clarify our theory of intensional knowledge representation for natural-language processing, as presented in previous papers and in light of objections raised by others. The essential claim is that tokens in a knowledge-representation system represent only intensions and not extensions. We are pursuing this investigation by building CASSIE, a computer model of a cognitive agent and, to the extent she works, a cognitive agent herself. CASSIE's mind is implemented in the SNePS knowledge-representation and reasoning system. (shrink)

This paper investigates the prospects of Rodney Brooks’ proposal for AI without representation. It turns out that the supposedly characteristic features of “new AI” (embodiment, situatedness, absence of reasoning, and absence of representation) are all present in conventional systems: “New AI” is just like old AI. Brooks proposal boils down to the architectural rejection of central control in intelligent agents—Which, however, turns out to be crucial. Some of more recent cognitive science suggests that we might do well to dispose of (...) the image of intelligent agents as central representation processors. If this paradigm shift is achieved, Brooks’ proposal for cognition without representation appears promising for full-blown intelligent agents—Though not for conscious agents. (shrink)

Peter Simons has argued that the expression ‘the universe’ is not a genuine singular term: it can name neither a single, completely encompassing individual, nor a collection of individuals. (It is, rather, a semantically plural term standing equally for every existing object.) I offer reasons for resisting Simons’s arguments on both scores.

This article explores the meeting of two approaches towards philosophy and education: the philosophy for children approach advocated by Lipman and others, and Schmid’s philosophical concept of Lebenskunst. Schmid explores the concept of the beautiful or good life by asking what is necessary for each individual to be able to develop their own art of living and which aspects of life are significant when shaping a good and beautiful life. One element of Schmid’s theory is the practical application of philosophy (...) through the notions of Bildung, reflection, prudence and practical wisdom, as well as the requirement for each individual to take responsibility for actively shaping their life as an artwork. In this sense, each person is the artist responsible for living their own beautiful life. We argue that there are useful parallels between Schmid’s concept of the art of living and P4C, such as the ideal of a holistic philosophy that is “lived.” The pragmatic approach of P4C focuses on the embodied learner who practices critical, caring and creative thinking. Both P4C and Schmid’s theory are reminiscent of the Aristotelian notion of practical wisdom, which allows for an approach to an education for life that prepares students to develop their own art of living.

Sequel to Part I. In these articles, I describe Cantor’s power-class theorem, as well as a number of logical and philosophical paradoxes that stem from it, many of which were discovered or considered (implicitly or explicitly) in Bertrand Russell’s work. These include Russell’s paradox of the class of all classes not members of themselves, as well as others involving properties, propositions, descriptive senses, class-intensions and equivalence classes of coextensional properties. Part II addresses Russell’s own various attempts to solve these paradoxes, (...) including strategies that he considered and rejected (limitation of size, the zigzag theory, etc.), as well as his own final views whereupon many purported entities that, if reified, lead to these contradictions, must not be genuine entities, but ‘logical fictions’ or ‘logical constructions’ instead.

ABSTRACT This essay focuses on two underlying presumptions that impinge on the effort of UNESCO to engender universal agreement on a set of bioethical norms: the conception of universality that pervades much of the document, and its disregard of structural inequalities that significantly impact health. Drawing on other UN system documents and recent feminist bioethics scholarship, we argue that the formulation of universal principles should not rely solely on shared ethical values, as the draft document affirms, but also on differences (...) in ethical values that obtain across cultures. UNESCO's earlier work on gender mainstreaming illustrates the necessity of thinking from multiple perspectives in generating universal norms. The declaration asserts the ‘fundamental equality of all human beings in dignity and rights’1 and insists that ‘the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social condition’2 yet it does not explicitly recognize disparities of power and wealth that deny equal dignity and rights to many. Without attention to structural (as opposed to merely accidental) inequities, UNESCO's invocation of rights is so abstract as to be incompatible with its avowed intention. (shrink)

Attempts to evaluate a belief or argument on the basis of its cause or origin are usually condemned as committing the genetic fallacy. However, I sketch a number of cases in which causal or historical factors are logically relevant to evaluating a belief, including an interesting abductive form that reasons from the best explanation for the existence of a belief to its likely truth. Such arguments are also susceptible to refutation by genetic reasoning that may come very close to the (...) standard examples given of supposedly fallacious genetic reasoning. (shrink)

The paper presents a paradoxical feature of computational systems that suggests that computationalism cannot explain symbol grounding. If the mind is a digital computer, as computationalism claims, then it can be computing either over meaningful symbols or over meaningless symbols. If it is computing over meaningful symbols its functioning presupposes the existence of meaningful symbols in the system, i.e. it implies semantic nativism. If the mind is computing over meaningless symbols, no intentional cognitive processes are available prior to symbol grounding. (...) In this case, no symbol grounding could take place since any grounding presupposes intentional cognitive processes. So, whether computing in the mind is over meaningless or over meaningful symbols, computationalism implies semantic nativism. (shrink)

Analytic epistemologists agree that, whatever else is true of epistemic justification, it is distinct from knowledge. However, if recent work by Jonathan Sutton is correct, this view is deeply mistaken, for according to Sutton justification is knowledge. That is, a subject is justified in believing that p iff he knows that p. Sutton further claims that there is no concept of epistemic justification distinct from knowledge. Since knowledge is factive, a consequence of Sutton’s view is that there are no false (...) justified beliefs. <br> Following Sutton, I will begin by outlining kinds of beliefs that do not constitute knowledge but that seem to be justified. I will then be in a position to critically evaluate Sutton’s arguments for his position that justification is knowledge, concluding that he fails to establish his bold thesis. In the course of so doing, I will defend the following rule of assertion: (The JBK-rule) One must: assert p only if one has justification to believe that one knows that p.<br>. (shrink)

A new proof style adequate for modal logics is defined from the polynomial ring calculus. The new semantics not only expresses truth conditions of modal formulas by means of polynomials, but also permits to perform deductions through polynomial handling. This paper also investigates relationships among the PRC here defined, the algebraic semantics for modal logics, equational logics, the Dijkstra???Scholten equational-proof style, and rewriting systems. The method proposed is throughly exemplified for S 5, and can be easily extended to other modal (...) logics. (shrink)

Abstract: According to certain dispositional accounts of meaning, an agent's meaning is determined by the dispositions that an idealized version of this agent has in optimal conditions. We argue that such attempts cannot properly fix meaning. For even if there is a way to determine which features of an agent should be idealized without appealing to what the agent means, there is no non-circular way to determine how those features should be idealized. We sketch an alternative dispositional account that avoids (...) this problem, according to which an agent's meaning is determined by the dispositions that an abstract version of this agent has in optimal conditions.

In his Meditations Descartes concludes that he is a res cogitans, an unextended entity whose essence is to be conscious. His reasoning in support of the conclusion that he exists entirely distinct from his body has seemed unconvincing to his critics. I attempt to show that the reasoning which he offers in support of his conclusion. although mistaken, is more plausible and his mistakes more interesting than his critics have acknowledged.

How does an engagement with religious traditions (broadly construed) illuminate and complicate the task of thinking through the ethics of eating? In this introduction, we survey some of the many food ethical issues that arise within various religious traditions and also consider some ethical positions that such traditions take on food. To say the least, we do not attempt to address all the ethical issues concerning food that arise in religious contexts, nor do we attempt to cover every tradition’s take (...) on food. We look at just a few traditions and a few interesting writings on food ethics and religion: What do they say about the ethics of eating? Why do they say these things? Here we use the terms “food ethics” and “religion” ecumenically as big tents under which many importantly different sorts of things may be grouped. Among the wide range of food ethical issues we consider in this chapter, for example, are religious views about the ethics of keeping, hurting, and killing animals, killing plants, dominion over creation, wastefulness, purity, blessing, atonement, and the connection between food and character. We realize, moreover, that it might be a stretch to label some of the views engaged by selected readings in this chapter as “religious” on a stringent understanding of that term; Lisa Kemmerer’s “Indigenous Traditions,” for instance, addresses some views that are recognizably spiritual but perhaps not religious in a strict sense. We hope that our ecumenical usage of the term can bring these important traditions to bear on the discussion without reducing them to something they are not. (shrink)

In this short response to Kerstein and Bognar, we clarify three aspects of the complete lives system, which we propose as a system of allocating scarce medical interventions. We argue that the complete lives system provides meaningful guidance even though it does not provide an algorithm. We also defend the investment modification to the complete lives system, which prioritizes adolescents and older children over younger children; argue that sickest-first allocation remains flawed when scarcity is absolute and ongoing; and argue that (...) Kerstein and Bognar are mistaken to base their allocation principles on differences in personhood. (shrink)

This paper is an attempt to argue that there existed a very prominent view of signs and signification in late sixteenth- and seventeenth-century Europe which can help us to understand several puzzling aspects of baroque culture. This view, called here "pansemioticism," constituted a fundamental part of the baroque conception of the world. After sketching the content and importance of pansemioticism, I will show how it can help us to understand the (from a modern perspective) rather puzzling concept of the polymath, (...) or polyhistor, which constituted the ideal of the baroque scientist. In this context I will also discuss a seventeenth century phenomenon essentially connected with polyhistorism, namely that of the early modem polyhistorical collections, the Wunderkamnmern. Since such a study needs a clearly determined focal point, we will concentrate on the last three quarters of the seventeenth century and will mainly discuss works by German authors of the time.

Most event-referring expressions are vague; it is utterly difficult, if not impossible, to specify the exact spatiotemporal location of an event from the words that we use to refer to it. We argue that in spite of certain prima facie obstacles, such vagueness can be given a purely semantic (broadly supervaluational) account.

The theory according to which most ordinary objects are mere “entia successiva”—sequences of distinct mereological aggregates, whose unity resides exclusively in our minds—is a variant of the standard, three-dimensional conception of objects. For the aggregates are, at bottom, endurants, i.e., entities that persist through time by being fully present at any time at which they exist. In this paper I compare this theory with the so-called “stage view”, according to which ordinary objects—indeed, all objects—are sequences of momentary entities that cannot (...) truly be said to persist through time. Both theories face a number of intuitive difficulties but the stage view, I argue, has a lot more to offer in return. (shrink)

From the dictum "ought implies can", it has been argued that no account of belief's normativity can avoid the unpalatable result that, for unbelievable propositions such as "It is raining and nobody believes that it is raining", one ought not to believe them even if true. In this article, I argue that this move only succeeds on a faulty assumption about the conjunction of doxastic "oughts.".

The researcher was prompted to conduct this study to give intervention of the alarming situation which there is a low performance in solving problems related to geometry in Grade IV Mathematics. This study was about on how to enhance the mathematical competencies of the grade IV pupils using a downloaded worksheets as a learning activity. This study focused in giving remediation applying the intervention materials. These resources give several approaches to attain mastery using distinct drill cards. The investigation was carried (...) out utilizing quasi-experimental design. During administering the pre-test and post-test, the researcher used the weighted mean and t-test to determine the mean percentage scores of the respondents. The respondents were 56 fourth grade learners enrolled in Marangog Elementary School and Tagnate Elementary School in Hilongos East District for the school year 2019 – 2020. At the end of the study, it was found out the use of downloaded math worksheets were found effective means of improving the mastery level. In addition, based on the results gathered, the downloaded math worksheets which were used in the drills or practice greatly contributed to the elimination of non-numerates, and give significantly increasing the number of pupils who mastered the competencies related to geometry. As a result, a proposed innovative teaching strategy is recommended. -/- . (shrink)

This paper investigates the emotional import of literary devices deployed in fiction. Reflecting on the often-favored approach in the analytic tradition that locates fictional characters, events, and narratives as sources of readers’ emotions, I attempt to broaden the scope of analysis by accounting for how literary devices trigger non-cognitive emotions. I argue that giving more expansive consideration to literary devices by which authors present content facilitates a better understanding of how fiction engages emotion. In doing so, I also explore the (...) somatic dimension of reading fiction. (shrink)

It would be an understatement to say that Russell was interested in Cantorian diagonal paradoxes. His discovery of the various versions of Russell’s paradox—the classes version, the predicates version, the propositional functions version—had a lasting effect on his views in philosophical logic. Similar Cantorian paradoxes regarding propositions—such as that discussed in §500 of The Principles of Mathematics—were surely among the reasons Russell eventually abandoned his ontology of propositions.1 However, Russell’s reasons for abandoning what he called “denoting concepts”, and his rejection (...) of similar “semantic dualisms” such as Frege’s theory of sense and reference—at least in “On Denoting”—made no explicit mention of any Cantorian paradox. My aim in this paper is to argue that such paradoxes do pose a problem for certain theories such as Frege’s, and early Russell’s, about how definite descriptions are meaningful. My first aim is simply to lay out the problem I have in mind. Next, I shall turn to arguing that the theories of descriptions endorsed by Frege and by Russell prior to “On Denoting” are susceptible to the problem. Finally, I explore what responses a.. (shrink)

The U.S. Supreme Court regards parental rights as fundamental. Such a status should subject any legal procedure that directly and substantively interferes with the exercise of parental rights to strict scrutiny. On the contrary, though, despite their status as fundamental constitutional rights, parental rights are routinely suspended or revoked as a result of procedures that fail to meet even minimal standards of procedural and substantive due process. This routine and cavalier deprivation of parental rights takes place in the context of (...) divorce where, during the pendency of litigation, one parent is routinely deprived of significant parental rights without any demonstration that a state interest exists—much less that there is a compelling state interest that cannot be achieved in any less restrictive way. In marked contrast to our current practice, treating parental rights as fundamental rights requires a presumption of joint legal and physical custody upon divorce and during the pendency of divorce litigation. The presumption may be overcome, but only by clear and convincing evidence that such an arrangement is harmful to the children. (shrink)

Proponents of human reproductive cloning do not dispute that cloning may lead to violations of clones' right to self-determination, or that these violations could cause psychological harms. But they proceed with their endorsement of human reproductive cloning by dismissing these psychological harms, mainly in two ways. The first tactic is to point out that to commit the genetic fallacy is indeed a mistake; the second is to invoke Parfit's non-identity problem. The argument of this paper is that neither approach succeeds (...) in removing our moral responsibility to consider and to prevent psychological harms to cloned individuals. In fact, the same commitment to personal liberty that generates the right to reproduce by means of cloning also creates the need to limit that right appropriately. Discussion of human reproductive cloning ought to involve a careful and balanced consideration of both the relevant aspects of personal liberty – the parents' right to reproductive freedom and the cloned child's right to self-determination.

The thesis of this paper is that utopianism is a theoretical necessity—we couldn’t, for example, engage in normative political philosophy without it—and, further, that in consciously embracing utopianism we will consequently experience an enrichment of our political lives. Thus, the title of my paper has a double meaning: it highlights the fact that utopianism always plays a normative role in political philosophy, as its concern is inevitably the promotion of a certain vision of the good life; and secondly it suggests (...) that there normatively ‘ought to be’ a recognized and respectable role for utopianism within political philosophy. The first meaning, I believe, is self-explanatory. Regarding the second, it expresses my hope to— in short— take what is old, and through a modest process of rehabilitation, make it new again.

This paper’s outline is as follows. In sections 1-3 I give an exposi¬tion of the Mind-Body Problem, with emphasis on what I believe to be the heart of the problem, namely, the Percepts-Qualia Nonidentity and its incompatibility with the Physical Closure Paradigm. In 4 I present the “Qualia Inaction Postulate” underlying all non-interactionist theo¬ries that seek to resolve the above problem. Against this convenient postulate I propose in section 5 the “Bafflement Ar¬gument,” which is this paper's main thesis. Sections 6-11 (...) critically dis¬cuss attempts to dismiss the Bafflement Argument by the “Baf¬flement=Mis¬perception Equation.” Section 12 offers a refutation of all such attempts in the form of a concise “Asymmetry Proof.” Section 13 points out the bearing of the Bafflement Argument on the evolutionary role of consciousness while section 14 acknowledges the price that has to be paid for it in terms of basic physical principles. Section 15 summarizes the paper, pointing out the inescapability of interactionist dualism. (shrink)

Politics, and in particular the question of the Palestinian-Israeli conflict, is currently dealt with rather through fiction and art, and much less through genuine political actions, is a strong sign of the failure of politics as a positive, voluntaristic political project. Rap /hip hop music, the most naturally political art, does not have the political agenda anymore. The particular history or Israeli rap illustrates this process in a striking way, embodying the recent evolution of the Israeli society. The country was (...) established on a political project and previously unknown social generosity. Yet, the economical and geopolitical context of Israel, as well as increasingly difficult relationship with Palestinians, made its citizens surprisingly uninterested in rethinking the political project of the country. Individual preoccupations, also economical, family and friends’ problems, started to occupy the central place in art and in daily life in Israel, and politics has been definitively associated to corruption and self-interest of an elite. Rap reflects this evolution, is its condensed version. (shrink)

One of the most historically recent and damaging blows to the reputation of utopianism came from its association with the totalitarian regimes of Hitler’s Third Reich and Mussolini’s Fascist party in World War II and the prewar era. Being an apologist for utopianism, it seemed to some, was tantamount to being an apologist for Nazism and all of its concomitant horrors. The fantasy principle of utopia was viewed as irretrievably bound up with the irrationalism of modern dictatorship. While these conclusions (...) are somewhat understandable given the broad strokes that definitions of utopia are typically painted with, I will show in this paper that the link between the mythos of fascism and the constructs of utopianism results from an unfortunate conflation at the theoretical level. The irrationalism of any mass ethos and the rationalism of the thoughtful utopian planner are, indeed, completely at odds with each other. I arrive at this conclusion via an analysis of the concepts of myth and narrative, and the relationships these have with the concept of utopia. (shrink)

The idea that we may continue to exist in a bodiless condition after our death has long played an important role in beliefs about immortality, ultimate rewards and punishments, the transmigration of souls, and the like. There has also been long and heated disagreement about whether the idea of disembodied existence even makes sense, let alone whether anybody can or does survive dissolution of his material form. It may seem doubtful that anything new could be added to the debate at (...) this late date, but I hope to show that this is not so. I will explore the problem of disembodiment from a somewhat different direction than has been tried before, one that leads to what seem to me more interesting and more definite conclusions about its unintelligibility. Furthermore, the approach I will be taking puts both the traditional mind-body problem and the competing claims of dualism and physicalism in a fresh light that can help us to understand better the nature of our embodied existence.

My aim in this paper is to draw Plotinus and Derrida together in a comparison of their respective appropriations of the famous “receptacle” passage in Plato's Timaeus (specifically, Plotinus' discussion of intelligible matter in Enneads 2.4 and Derrida's essay on Timaeus entitled “Kh ō ra”). After setting the stage with a discussion of several instructive similarities between their general philosophical projects, I contend that Plotinus and Derrida take comparable approaches both to thinking the origin of the forms and to problematizing (...) the stability of the sensible/intelligible opposition. With these parallels in focus, I go on to explain how examining such points of contact can help us to dismantle the canonical constructs of “Plotinus the metaphysician” and “Derrida the anti-metaphysician” that have obscured important connections between Neoplatonism and deconstruction, and suppressed latent resources within the Platonic tradition itself for deconstructing the dualistic ontology of so-called “Platonic metaphysics.”.

A look at Mach's work on monocular stereoscopy with relation to Mach Bands and the sensation of space.

In The Realm of Reason (2004), Christopher Peacocke develops a “generalized rationalism” concerning, among other things, what it is for someone to be “entitled”, or justified, in forming a given belief. In the course of his discussion, Peacocke offers two arguments to the best explanation that aim to undermine scepticism and establish a justification for our belief in the reliability of sense perception, respectively. If sound, these ambitious arguments would answer some of the oldest and most vexing epistemological problems. In (...) this paper I will evaluate these arguments, concluding that they are inconclusive at best. Despite offering some interestingly original arguments, Peacocke gives us no reason to think that scepticism is false, and that perception is generally reliable. (shrink)

As evidence of the unintended consequences of industrial farm animal production continues to mount, it is becoming increasingly clear that, far from being a trivial matter of personal preference, eating is an activity that has deep moral and spiritual significance. Surprising as it may sound, the simple question of what to eat can prompt Christians daily to live out their spiritual vision of Shalom for all creatures--to bear witness to the marginalization of the poor, the exploitation of the oppressed, the (...) suffering of the innocent, and the degradation of the natural world, and to participate in the reconciliation of these ills through intentional acts of love, justice, mercy, and good stewardship. The aim of this work is to understand the cultivation of more intentional "compassionate eating" habits as a form of engaged Christian discipleship that responds to a wide array of practical, moral, and spiritual problems affecting all aspects of creation--human, animal, and environmental. The guiding suggestion is that compassionate eating is a spiritual discipline that offers a symbolically significant and practically effective way to live in faithful anticipation of the "peaceable kingdom" described in Judeo-Christian creation and redemption narratives.

Suppose we get a chance to ask an angel a question of our choice. What should we ask to make the most of our unique opportunity? Ned Markosian has shown that the task is trickier than it might seem.

The new Chomskian orthodoxy denies that our linguistic competence gives us knowledge *of* a language, and that the representations in the language faculty are representations *of* anything. In reply, I have argued that through their intuitions speaker/hearers, (but not their language faculties) have knowledge of language, though not of any externally existing language. In order to count as knowledge, these intuitions must track linguistic facts represented in the language faculty.

Over three decades ago, in a brief but provocative essay, Paul Ziff argued for the thesis that robots cannot have feelings because they are "mechanisms, not organisms, not living creatures.

In the first half of my paper I review Ziff's arguments against the idea that robots could be conscious, especially his appeal to (...) our linguistic usage. In the second half of the essay I try to provide a deeper ontological understanding of why we ought not attribute minds to nonliving artifacts. I argue that inanimate mechanisms are incapable of genuinely active and purposive behavior. They are importantly different in kind from living human beings and animals. (shrink)

During the coronavirus pandemic, communities have faced shortages of important healthcare resources such as COVID-19 vaccines, medical staff, ICU beds and ventilators. Public health officials in the U.S. have had to make decisions about two major issues: which infected patients should be treated first (triage), and which people who are at risk of infection should be inoculated first (vaccine distribution). Following Beauchamp and Childress’s principlism, adopted guidelines have tended to value both whole lives (survival to discharge) and life-years (survival for (...) years past discharge). This process of collective moral reasoning has revealed our common commitment to both Kantian and utilitarian principles. For Kant, respecting people’s rights entails that we ought to value whole lives equally. Therefore we ought to allocate resources so as to maximise the number of patients who survive to discharge. By contrast, the principle of utility has us maximise life-years so that people can satisfy more of their considered preferences. Although people are treated impartially in the utilitarian calculus, it does not recognise their equal worth. Subjecting Kantian ethics and utilitarianism to the process of reflective equilibrium lends support to the idea that we need a pluralistic approach that would accommodate our moral intuitions regarding both the equal value of whole lives and the additive value of life-years.
