Technologies to rapidly alert people when they have been in contact with someone carrying the coronavirus SARS-CoV-2 are part of a strategy to bring the pandemic under control. Currently, at least 47 contact-tracing apps are available globally. They are already in use in Australia, South Korea and Singapore, for instance. And many other governments are testing or considering them. Here we set out 16 questions to assess whether — and to what extent — a contact-tracing app is ethically justifiable.

This book takes seriously the idea that at least some groups, such as corporations and governments, are genuine agents with mental states on which they act. For instance, in morally assessing a government’s response to the coronavirus pandemic, we are interested in what the government knew at various points as the pandemic developed. And in predicting the outcome of the current war in Ukraine, we might ask what Russia believes about the West’s determination to defend Ukraine. The book examines a (...) range of phenomena central to the epistemic and moral assessment of groups: group evidence, group belief, the basis of group belief, group justified belief, group knowledge, group motivation, and group blameless ignorance. Overall, the book defends a ‘non-summative’ functionalist view of groups. On a non-summative account of group phenomena, it is neither necessary nor sufficient for a group to have a property α that some/most/all of its members have that same property. By contrast, on a summative account it is necessary and sufficient for a group to have a property α that some/most/all of its members have that same property. Across the book I provide new arguments for non-summativism and new accounts of key group phenomena many of which have been relatively neglected in existing literature. While I provide independent arguments for a non-summative view of each phenomenon discussed, the conclusions of the chapters are mutually reinforcing. For adopting a non-summative account of one group phenomenon motivates adopting a non-summative account of others. (shrink)

Grounding, understood as a primitive posit operative in contexts where metaphysical dependence is at issue, is not able on its own to do any substantive work in characterizing or illuminating metaphysical dependence---or so I argue in 'No Work for a Theory of Grounding' (Inquiry, 2014). Such illumination rather requires appeal to specific metaphysical relations---type or token identity, functional realization, the determinable-determinate relation, the mereological part-whole relation, and so on---of the sort typically at issue in these contexts. In that case, why (...) posit 'big-G' Grounding in addition to the 'small-g' grounding relations already in the metaphysician's toolkit? The best reasons for doing so stem from the Unity argument, according to which the further posit of Grounding is motivated as an apt unifier of the specific relations, and the Priority argument, according to which Grounding is needed in order to fix the direction of priority of the specific relations. I previously considered versions of these arguments, and argued that they did not succeed; in two papers, however, Jonathan Schaffer aims to develop a better version of the Unity argument, and offers certain objections to my reasons for rejecting the Priority argument. Here I consider these new arguments for Grounding. (shrink)

According to the naïve, pre-theoretic conception, lying seems to be characterized by the intent to deceive. However, certain kinds of bald-faced lies appear to be counterexamples to this view, and many philosophers have abandoned it as a result. I argue that this criticism of the naïve view is misplaced; bald-faced lies are not genuine instances of lying because they are not genuine instances of assertion. I present an additional consideration in favor of the naïve view, which is that abandoning it (...) comes at an extremely high price; alternative accounts which eschew the intent-to-deceive condition on lying have difficulty distinguishing lies from non-literal speech.

According to a number of contemporary theorists, aesthetic reasons can invite or entice us but never compel us. In this paper, I develop a Kantian account of the normative force of aesthetic reasons. While Kant would likely agree that aesthetic reasons do not give rise to obligations, his account nevertheless gives us the resources for explaining how aesthetic reasons can still have more force than merely enticing reasons. This account appeals to the distinct normativity of aesthetic judgments on Kant's theory (...) and the way in which this kind of normativity structures aesthetic exchanges with other judging subjects. I argue that, in addition to the moral reasons we have for appreciating and preserving beauty, Kant’s account can accommodate distinctly aesthetic reasons for doing so that stem from our membership in aesthetic communities.

Here I compare two accounts of metaphysical indeterminacy (MI): first, the 'meta-level' approach described by Elizabeth Barnes and Ross Cameron in the companion to this paper, on which every state of affairs (SOA) is itself precise/determinate, and MI is a matter of its being indeterminate which determinate SOA obtains; second, my preferred 'object-level' determinable-based approach, on which MI is a matter of its being determinate---or just plain true---that an indeterminate SOA obtains, where an indeterminate SOA is one whose constitutive object (...) has a determinable property, but no unique determinate of that determinable. In S1, I first note an important difference between our accounts, concerning whether MI is taken to induce propositional indeterminacy; in S2, I highlight and defend certain advantages of my account; in S3, I address certain of Barnes and Cameron's objections to my account.

To what degree has biology influenced and shaped the development of moral systems? One way to determine the extent to which human moral systems might be the product of natural selection is to explore behaviour in other species that is analogous and perhaps homologous to our own. Many non-human primates, for example, have similar methods to humans for resolving, managing, and preventing conflicts of interests within their groups. Such methods, which include reciprocity and food sharing, reconciliation, consolation, conflict intervention, and (...) mediation, are the very building blocks of moral systems in that they are based on and facilitate cohesion among individuals and reflect a concerted effort by community members to find shared solutions to social conflict. Furthermore, these methods of resource distribution and conflict resolution often require or make use of capacities for empathy, sympathy, and sometimes even community concern. Non-human primates in societies in which such mechanisms are present may not be exactly moral beings, but they do show signs of a sense of social regularity that -- just like the norms and rules underlying human moral conduct -- promotes a mutually satisfactory modus vivendi.

In this paper I investigate what it is for a group to believe something for a reason. I defend a non-summative account on which a group can believe that p for a reason even though none of its members believe that p for that reason. By contrast, a summative account would hold that the reason for which a group believes that p is a function of the reason for which its members believe that p. I argue that the proposed non-summative (...) account deals better with cases in which members of a group believe that p for different reasons. I also defend it against a range of objections, including that it conflicts with epistemic norms for assertion and action. (shrink)

The paper asks whether diagrams in mathematics are particularly fruitful compared to other types of representations. In order to respond to this question a number of examples of propositions and their proofs are considered. In addition I use part of Peirce’s semiotics to characterise different types of signs used in mathematical reasoning, distinguishing between symbolic expressions and 2-dimensional diagrams. As a starting point I examine a proposal by Macbeth. Macbeth explains how it can be that objects “pop up”, e.g., as (...) a consequence of the constructions made in the diagrams of Euclid, that is, why they are fruitful. It turns out, however, that diagrams are not exclusively fruitful in this sense. By analysing the proofs given in the paper I introduce the notion of a ‘faithful representation’. A faithful representation represents as either an image or as a metaphor. Secondly it represents certain relevant relations. Thirdly manipulations on the representations respect manipulations on the objects they represent, so that new relations may be found. The examples given in the paper illustrate how such representations can be fruitful. These examples include proofs based on both symbolic expressions as well as diagrams and so it seems diagrams are not special when it comes to fruitfulness. Having said this, I do present two features of diagrams that seem to be unique. One consists of the possibility of exhibiting the type of relation in a diagram—or simply showing that a relation exists—as a contrast to stating in words that it exists. The second is the spatial configurations possible when using diagrams, e.g., allowing to show multiple relations in a single diagram. (shrink)

The World Health Organisation declared COVID-19 a global pandemic on 11th March 2020, recognising that the underlying SARS-CoV-2 has caused the greatest global crisis since World War II. In this chapter, we present a framework to evaluate whether and to what extent the use of digital systems that track and/or trace potentially infected individuals is not only legal but also ethical.

We standardly attribute beliefs to both individuals and organised groups, such as governments, corporations and universities. Just as we might say that an individual believes something, for instance that oil prices are rising, so we might say that a government or corporation does. If groups are to genuinely have beliefs, then they need states with the characteristic features of beliefs. One feature standardly taken to characterise beliefs is their mind to world direction of fit: they should fit the way the (...) world is. By contrast, desires are standardly taken to have a world to mind direction of fit: they aim for the world to be a certain way and are satisfied when the world fits them. Recently, Lackey ( 2021 ) has appealed to direction of fit to argue against certain nonsummative accounts of group belief. Here, I argue that on deeper inspection, belief’s mind to world direction of fit is difficult to accommodate on summative accounts of group belief including Lackey’s own neo-summative account. Further, I argue that direction of fit considerations in fact motivate the main non-summative approaches to belief, namely functionalism and interpretationism. Along the way, we see how addressing the issue of the direction of fit of group beliefs raises important questions about how to understand group evidence and its relationship to the evidence of members.

According to evolutionary accounts of distinct emotions, these emotions are shaped by natural selection to adjust the physiological, psychological, cognitive, and behavioral parameters of an organism to facilitate its capacity to respond adaptively to threats and opportunities present in the environment. This account has a number of implications, most notably: (a) each distinct emotion serves, or served, an adaptive function, and (b) emotions are comprised of multiple components, all of which should be functional. In this article, I briefly outline an (...) evolutionary approach to understanding distinct emotions, then explain how this approach could be falsified, how one’s own emotion experience differs from the observation of an emotion experience in someone else, and why variability in emotional responding should be expected.

Every paper in this collection is worth reading, for one reason or another. Still, due to certain problematic metametaphysical presuppositions most of these discussions miss the deeper mark, on the pessimist as well as the optimist side. My reasons for thinking this come from considering how best to answer three metametaphysical questions. First, why be pessimistic about metaphysics – why be Carnapian in a post-positivist age? There is, I’ll suggest, a post-positivist strategy for reviving Carnapian pessimism, but it is almost (...) entirely neglected here; and the motivations that pessimists offer instead are not compelling. Second, why think that the best way to approach metametaphysical questions is by attention to features of language, and in particular to quantifier semantics, in ordinary or ontological language(s)? Here again we are offered little motivation for this supposition, which, notwithstanding its acceptance by nearly all contributors, faces clear difficulties. Third, granting that quantification is somehow bound up with first-order questions about what exists, what is the nature of this connection, and what are the associated implications for metametaphysics? Here I find the accounts of the connection on offer implausible, especially as compared to an alternative that makes better sense of metaphysical practice and disagreement. The moral following consideration of these questions is that real progress in metametaphysics is likely to occur less by attention to semantic issues pertaining to representation, translation and quantification and more to non-semantic issues pertaining to epistemology and metaphysical determinacy.

In what does philosophical progress consist? 'Vertical' progress corresponds to development within a specific paradigm/framework for theorizing (of the sort associated, revolutions aside, with science); 'horizontal' progress corresponds to the identification and cultivation of diverse paradigms (of the sort associated, conservativism aside, with art and pure mathematics). Philosophical progress seems to involve both horizontal and vertical dimensions, in a way that is somewhat puzzling: philosophers work in a number of competing frameworks (like artists or mathematicians), while typically maintaining that only (...) one of these is correct (like scientists). I diagnose this situation as reflecting that we are presently quite far from the end of inquiry into philosophical methodology. The good news is that we appear to be making advances on this score. The bad news is that failure to recognize or make explicit that our standards are in flux often leads to dogmatism, as I illustrate by attention to three assumptions presently operative in metaphysical and metametaphysical contexts. I close by identifying a tension between vertical and horizontal progress in philosophy, and suggesting an updated version of Carnap's principle of tolerance for new philosophical forms. (shrink)

This article discusses the role of diagrams in mathematical reasoning in the light of a case study in analysis. In the example presented certain combinatorial expressions were first found by using diagrams. In the published proofs the pictures were replaced by reasoning about permutation groups. This article argues that, even though the diagrams are not present in the published papers, they still play a role in the formulation of the proofs. It is shown that they play a role in concept (...) formation as well as representations of proofs. In addition we note that 'visualization' is used in two different ways. In the first sense 'visualization' denotes our inner mental pictures, which enable us to see that a certain fact holds, whereas in the other sense 'visualization' denotes a diagram or representation of something.

The concept of homology arose from classical studies of comprative morphology, and took on a new signficance with the advent of evolutionary theory. It is currentlyl undergoing antoher metamorphosis: many developmental geneticists now dfine homology as shared patterns of gene expression.

We argue the although developmental genetic data can help identify homologus structures. they are niether necessary nor sufficient, (...) and do not in any case jutify a new definition of homology.

Heidegger in America explores the surprising legacy of his life and thought in the United States of America. As a critic of modern life, Heidegger often lamented the growing global influence of all things American. However, it was precisely in America where his thought inspired the work of generations of thinkers – not only philosophers but also theologians, architects, novelists, and even pundits. As a result, the reception and dissemination of Heidegger's philosophical writings transformed the intellectual and cultural history of (...) the United States at a time when American influence was itself transforming the world. A case study in the complex and sometimes contradictory process of transnational exchange, Heidegger in America recasts the scope and methods of contemporary intellectual and cultural history in the age of globalization, challenging what we think we know about Heidegger and American ideas simultaneously.

In this paper, I argue that although Kant’s account of empirical schemata in the Critique of Pure Reason is primarily used to explain the shared content of intuitions and empirical concepts, it is also informed by methodological problems in natural history. I argue that empirical schemata, which are rules for determining the spatiotemporal form of objects, not only serve to connect individual intuitions with concepts, but also concern the very features of objects on the basis of which they were connected (...) and ordered in taxonomic systems based on similarity of form. I then suggest that Kant likely had scientific illustrations in mind in his discussion of empirical images in the Schematism chapter and that his account of schemata can help explain the epistemic function of these images in early modern science.

Two experiments investigated the mechanism by which listeners adjust their interpretation of accented speech that is similar to a regional dialect of American English. Only a subset of the vowels of English (the front vowels) were shifted during adaptation, which consisted of listening to a 20‐min segment of the “Wizard of Oz.” Compared to a baseline (unadapted) condition, listeners showed significant adaptation to the accented speech, as indexed by increased word judgments on a lexical decision task. Adaptation also generalized to (...) test words that had not been presented in the accented passage but that contained the shifted vowels. A control experiment showed that the adaptation effect was specific to the direction of the shift in the vowel space and not to a general relaxation of the criterion for what constitutes a good exemplar of the accented vowel category. Taken together, these results provide evidence for a context‐specific vowel adaptation mechanism that enables a listener to adjust to the dialect of a particular talker. (shrink)

What is the nature of the evidence provided by thought experiments in philosophy? For instance, what evidence is provided by the Gettier thought experiment against the JTB theory of knowledge? According to one view, it provides as evidence only a certain psychological proposition, e.g. that it seems to one that the subject in the Gettier case lacks knowledge. On an alternative, nonpsychological view, the Gettier thought experiment provides as evidence the nonpsychological proposition that the subject in the Gettier case lacks (...) knowledge (e.g., Williamson 2007). Given the centrality of thought experiments to philosophical enquiry, the correct account of thought experiment evidence is important for understanding the nature of philosophical methodology. Further, Williamson argues that a misguided adherence to the psychological view of thought experiment evidence encourages scepticism about philosophy since it opens a gap between our evidence and the nonpsychological subject matter of philosophy. The main aim of this paper is to defend the psychological view against recent objections. In particular, I argue that even if thought experiment evidence is psychological, it can still provide justification for non-psychological claims which are the subject matter of philosophy. (shrink)

Previous meta-analyses support a female advantage in decoding non-verbal emotion (Hall, 1978, 1984), yet the mechanisms underlying this advantage are not understood. The present study examined whether the female advantage is related to greater female attention to the eyes. Eye-tracking techniques were used to measure attention to the eyes in 19 males and 20 females during a facial expression recognition task. Women were faster and more accurate in their expression recognition compared with men, and women looked more at the eyes (...) than men. Positive relationships were observed between dwell time and number of fixations to the eyes and both accuracy of facial expression recognition and speed of facial expression recognition. These results support the hypothesis that the female advantage in facial expression recognition is related to greater female attention to the eyes. (shrink)

I argue that Cartesian skepticism about the external world leads to a vicious regress of skeptical attitudes, the only principled and unproblematic response to which requires refraining from taking the very first skeptical step.

In this paper I discuss a key issue for group moral responsibility, namely whether we can make sense of a group acting for one reason rather than another. The notion of acting for one reason rather than another is central to standard accounts of individual agency and responsibility; and also determines whether an individual is blameworthy or praiseworthy for an action. Thus if we model group responsibility on individual responsibility, we need to be able to make sense of a group (...) acting for one reason rather than another. In this paper, I raise problems for both summative and inflationary accounts of what it is for a group to act on a reason, before suggesting several potential solutions at the end. (shrink)

Editors' introduction to Puncta's February 2022 Special Issue, "Pandemic Politics and Phenomenology.".

Contextualism is motivated by cases in which the intuitive correctness of a range of phenomena, including knowledge attributions, assertions and reasoning, depends on the attributor's context. Contextualists offer a charitable understanding of these intuitions, interpreting them as reflecting the truth value of the knowledge attributions and the appropriateness of the relevant assertions and reasoning. Here, I investigate a range of different invariantist accounts and examine the extent to which they too can offer a charitable account of the contextualist data.

This book shows how environmental decline relates to human health and to health care practices in the U.S. and other industrialized countries. It outlines the environmental trends that will strongly affect health, and challenges us to see the connections between ways of practicing medicine and the very environmental problems that damage ecosystems and make people sick. In addition to philosophical analysis of the converging values of bioethics and envrionmental ethics, the book offers case studies as well as a number of (...) practical suggestions for moving health care toward sustainability.

The words in children's language learning environments are strongly predictive of cognitive development and school achievement. But how do we measure language environments and do so at the scale of the many words that children hear day in, day out? The quantity and quality of words in a child's input are typically measured in terms of total amount of talk and the lexical diversity in that talk. There are disagreements in the literature whether amount or diversity is the more critical (...) measure of the input. Here we analyze the properties of a large corpus of speech to children and simulate learning environments that differ in amount of talk per unit time, lexical diversity, and the contexts of talk. The central conclusion is that what researchers need to theoretically understand, measure, and change is not the total amount of words, or the diversity of words, but the function that relates total words to the diversity of words, and how that function changes across different contexts of talk.

Growing nursing workforce maldistributions impede rural healthcare access globally. In‐depth exploration of underlying philosophical ideas about rural health in nursing curricular could support recruitment and retention of nurses who are well positioned to support and advocated for health care and services relevant to their communities. Through a lens of positionality, the purpose of this paper is to explore rural health and nursing within the United States and Australia from the perspective of undergraduate students. Recognizing that both countries have ‘first world’ (...) health services, issues of access to services associated with systemic and structural biases were significant features identified by participants. Their perceptions were supported by discussion with attendees of the 26th International Nursing Philosophy Conference from several countries, during a presentation titled ‘What is different about rural health nursing: A philosophical exploration.’ This international consistency suggests that systemic and structural biases are global phenomena. While exposure to rural health and rural nursing may be beneficial for recruitment, preparing nurses for rural practice requires more than educating students to complete clinical tasks. Uncovering collaboration, advocacy and policy development opportunities for nurses in rural communities could move the dial from recruiting rural nurses to fulfill immediate needs to retention of well‐educated and highly skilled nurses. Building a stronger philosophical base for rural healthcare inclusive of all people, honouring their distinguishing characteristics such as age, gender, ethnicity, is long overdue. Positionality can inform how nurses across the globe relate to other countries' governments, cultures, norms, values, expectations, etc., which can influence the advancement of the profession and address social inequities among rural populations.

This article explores notions about Nietzsche’s career as a philologist and his fascination with the Greeks. It considers his interest in Homer and the Greek philosophers—in particular, Heraclitus and Pyrrho. For Nietzsche, ancient Greeks such as Heraclitus and Homer were interesting not because of their doctrines, but because of the example they themselves provided of certain psychological types. Like the ancient skeptics following Pyrrho, Nietzsche was generally more interested in the psychological consequences of philosophical doctrines than in their content, and (...) like those skeptics he often rejected any ambitions to limn the true nature of reality.

As children and adolescents receive increased research attention, ethical issues related to obtaining informed consent for pediatric intervention research have come into greater focus. In this article, we conceptualize parent permission and child assent within a goodness-of-fit framework that encourages investigators to create consent procedures “fitted” to the research context, the child's cognitive and emotional maturity, and the family system. Drawing on relevant literature and a hypothetical case example, we highlight four factors investigators may consider when constructing consent procedures that (...) best reflect participants' rights, concerns, and well-being: (a) the child's current assent capacity and the likely impact of study information on the child's mental and physical development, (b) parents' understanding of their child's treatment needs and distinctions between treatment and clinical trials research, (c) the family's history of shared decision making, and (d) the child's strivings for autonomy within the context of their parents' duty to make decisions in the child's best interest.

This paper takes as a starting point certain notions from Peirce's writings and uses them to propose a picture of the part of mathematical practice that consists of hypothesis formation. In particular, three processes of hypothesis formation are considered: abstraction, generalisation, and an abductive-like inference. In addition Peirce's pragmatic conception of truth and existence in terms of higher-order concepts are used in order to obtain a kind of pragmatic realist picture of mathematics.

I consider whether one particular anti-individualist claim, the doctrine of object-dependent thoughts (DODT), is compatible with the Principle of Privileged Access, or PPA, which states that, in general, a subject can have non-empirical knowledge of her thought contents. The standard defence of the compatibility of anti-individualism and PPA emphasises the reliability of the process which produces a subject's second order beliefs about her thought contents. I examine whether this defence can be applied to DODT, given that DODT generates the possibility (...) of illusions of thought. Drawing on general epistemological literature, I distinguish several senses of reliability, and argue that in the relevant sense-'global reliability'-DODT does sometimes threaten reliability and hence PPA.

One of the major adaptations during the evolution of Homo sapiens was an increase in brain size. Here we present evidence that a significant and substantial proportion of variation in brain size may be related to changes in temperature. Based on a sample of 109 fossilized hominid skulls, we found that cranial capacities were highly correlated with paleoclimatic changes in temperature, as indexed by oxygen isotope data and sea-surface temperature. Indeed, as much as 52% of the variance in the cranial (...) capacity of these skulls could be accounted for by temperature variation at 100 ka intervals. As an index of more short-term seasonal fluctuations in temperature, we examined the latitude of the sites from which the crania originated. More than 22% of the variance in cranial capacity of these skulls could be accounted for by variation in equatorial distance. (shrink)

_Objective:_ The aim of the current study was to investigate associations, unique and interactive, between mothers’ and children’s histories of childhood sexual abuse (CSA) and children’s psychiatric outcomes using an intergenerational perspective. Further, we were particularly interested in examining whether maternal reflective functioning about their own trauma (T-RF) was associated with a lower likelihood of children’s abuse exposure (among children of CSA-exposed mothers). _Methods:_ One hundred and eleven children ( M age = 9.53 years; 43 sexual abuse victims) and their (...) mothers ( M age = 37.99; 63 sexual abuse victims) participated in this study. Mothers completed the Parent Development Interview (PDI), which yielded assessments of RF regarding their own experiences of abuse, and also reported on their children’s internalizing and externalizing symptoms. _Results:_ Children of CSA-exposed mothers were more likely to have experienced CSA. A key result was that among CSA-exposed mothers, higher maternal T-RF regarding their own abuse was associated with lower likelihood of child CSA-exposure. Mothers’ and children’s CSA histories predicted children’s internalizing and externalizing symptoms, such that CSA exposure for mother or child was associated with greater symptomatology in children. _Conclusion:_ The findings show that the presence of either maternal or child CSA is associated with more child psychological difficulties. Importantly in terms of identifying potential protective factors, maternal T-RF is associated with lower likelihood of CSA exposure in children of CSA-exposed mothers. We discuss these findings in the context of the need for treatments focusing on increasing T-RF in mothers and children in the context of abuse to facilitate adaptation and reduce the intergenerational risk.

Many if not all evidential languages have a mirative evidential: an indirect evidential that can, in some contexts, mark mirativity (the expression of speaker surprise) instead of indirect evidence. We address several questions posed by this systematic polysemy: What is the affinity between indirect evidence and speaker surprise? What conditions the two interpretations? And how do mirative evidentials relate to other mirative markers? We propose a unified analysis of mirative evidentials where indirect evidentiality and mirativity involve a common epistemic component. (...) A mirative interpretation requires a close temporal proximity between the speech event and the event of the speaker's learning the at-issue content. (shrink)

Hossack (2007) defends what he calls the rationalist thesis: the thesis that necessity reduces to (or at least always coincides with) a priori knowledge. In this paper I discuss some features of Hossack’s rationalist account of necessity. In the first half, I attempt to fill in a missing link in the rationalist thesis, connecting the notions of primitiveness of facts and a priori modes of presentation. In the second half, I complain that the strategy of dissolving counterexamples is not enough, (...) and that a general principle connecting necessity and a prioricity is needed. I suggest further kinds of counterexamples that might arise, but rather than demand a response to each counterexample, I suggest that they highlight the need for a general argument for the rationalist thesis.

Given the long-standing controversy about whether the brain-dead should be considered alive in an irreversible coma or dead despite displaying apparent signs of life, the ethical and policy issues posed when family members insist on continued treatment are not as simple as commentators have claimed. In this article, we consider the kind of policy that should be adopted to manage a family's insistence that their brain-dead loved one continues to receive supportive care. We argue that while it would be ethically (...) inappropriate to continue to devote scarce acute care resources to such patients in a hospital setting, it may not be ethically inappropriate for patients to receive these resources in certain other settings. Thus, if a family insists on continuing to care for their brain-dead loved at their home, we should not, from a policy perspective, interfere with the family's wishes. We also argue that healthcare professionals should make some effort to facilitate the transfer of brain-dead patients to these other settings when families insist on continued treatment despite being informed about the lack of any potential for recovery of consciousness. Our arguments are strengthened by the fact that patients in a persistent vegetative state, who, when correctly diagnosed, also have no potential for recovery of consciousness, are routinely transferred from hospitals to nursing homes or long-term care facilities where they continue to be ventilated, tube fed and to receive other supportive care. We also briefly explore the question of who should be responsible for the costs of such treatment at the long-term care facility. (shrink)

In this paper, it is argued that selection and drift might be distinct. This contradicts recent arguments by Brandon (forthcoming) and Matthen and Ariew (2002) that such a distinction “violates sound probabilistic thinking” (Matthen and Ariew 2002, 62). While their arguments might be valid under certain assumptions, they overlook a possible way to make sense of the distinction. Whether this distinction makes sense, I argue, depends on the source of probabilities in natural selection. In particular, if the probabilities used in (...) defining fitness values are at least partly a result of abstracting from or ignoring certain features of the environment, then selection and drift might in fact be causally distinct.
