In this book Terence Parsons revives the older tradition of taking such objects at face value. Using various modern techniques from logic and the philosophy of language, he formulates a metaphysical theory of nonexistent objects. The theory is given a formalization in symbolism rich enough to contain definite descriptions, modal operators, and epistemic contexts, and the book includes a discussion which relates the formalized theory explicitly to English.

In early 2020, Sobeys—one of Canada’s largest food retailers—partnered with Infarm Indoor Vertical Farming to install hydroponic vertical farming units in their retail locations. This partnership aims to build a resilient agri-food ecosystem in the face of climate change. Infarm is one of few vertical farming start-ups to reach ‘unicorn’ status in the recent boom of venture capital-backed urban farming solutions. Working to mitigate the climate crisis is critical, but I take venture capital as the spokesperson for green technologies as (...) intuitively strange. Actor-network theory is a powerful tool for describing networks in which modern technical objects are embedded. By mapping the nodes of Infarm’s actor-network and analyzing how and by what the expertise of a ‘black-boxed’ vertical farm is negotiated, we can identify obligatory points of passage that render the epistemology of the network durable. Ultimately, Infarm’s vertical farming practice and its climate change mitigation logics are moulded by venture capital and its biopolitical epistemology of valuation—a way of thinking that conceptualizes ‘life’, biology and, therefore, the climate in terms of political economy.

The following quotation, from Frank Jackson, is the beginning of a typical exposition of the debate between those metaphysicians who believe in temporal parts, and those who do not: The dispute between three-dimensionalism and four-dimensionalism, or more precisely, that part of the dispute we will be concerned with, concerns what persistence, and correllatively, what change, comes to. Three-dimensionalism holds that an object exists at a time by being wholly present at that time, and, accordingly, that it persists if it is (...) wholly present at more than one time. For short, it persists by enduring. Four-dimensionalism holds that an object exists at a time by having a temporal part at that time, and it persists if it has distinct temporal parts at more than one time. For short, it persists by perduring. In the light of these comments, some readers will perhaps find the question that forms the title of this paper a little puzzling. They may have learned to use the terms ‘fourdimensionalism’ ‘perdurantism’ and ‘belief in temporal parts’ interchangeably; or perhaps even to define one in terms of the other. Such a usage, however, is inapposite. We might imagine a Flatland-like world of two spatial dimensions and one temporal, whose philosophers are divided between a theory of persistence on which they persist by having temporal parts, and a theory on which they persist by being wholly located in each of several times. This is just the same issue we face, but at least the label ‘four-dimensionalism’ seems inapposite: the four-dimensionalist Flatlanders believe in only three dimensions! (shrink)

Technologies for mitigating and adapting to climate change are inherently political. Their development, diffusion and deployment will have uneven impacts within and across national borders. Bringing the governance of climate technologies under democratic control is imperative but impeded by the global scale of governance and its polycentric nature. This article draws on innovative theorising in the deliberative democracy tradition to map possibilities for global democratic governance of climate technologies. It is argued that this domain is not beyond the reach of (...) democracy. Civil society has a unique and expanded role to play in generating democratic legitimacy by fostering public deliberation; translating and transmitting concepts, ideas and messages; and promoting and facilitating deliberative accountability.

Task shifting is increasingly used to address human resource shortages impacting HIV service delivery in low- and middle-income countries. By shifting basic tasks from higher- to lower-trained cadres, such as Community Health Workers, task shifting can reduce overhead costs, improve community outreach, and provide efficient scale-up of essential treatments like antiretroviral therapies. Although there is rich evidence outlining positive outcomes that CHWs bring into HIV programs, important questions remain over their place in service delivery. These challenges often reflect concerns over (...) whether CHWs can mitigate HIV through a means that does not overlook the ethical and practical constraints that undergird their work. Ethical and practical guidance thus needs to become the cornerstone of CHW deployment. This paper analyzes such challenges through the lens of Ethical Principlism. We examined papers identifying substantive and ethical challenges impacting CHWs as they provide HIV services in low- and middle-income contexts. To do this, we analyzed papers written in English and published from year 2000 or later. These articles were identified using MEDLINE, Cochrane Database of Systematic Reviews, and Google Scholar databases. In total, 465 articles were identified, 78 of which met our inclusion criteria. Article reference lists and grey literature were also examined. CHWs experience specific challenges while carrying out their duties, such as conducting emotionally- and physically-demanding tasks with often inadequate training, supervision and compensation. CHWs have also been poorly integrated into health systems, which not only impacts quality of care, but can hinder their prospects for promotion and lead to CHW disempowerment. As we argue, these challenges can be addressed if a set of ethical principles is prioritized, which specifically entail the principles of respect for persons, justice, beneficence, proportionality and cultural humility. CHWs play a crucial role in HIV service delivery, yet the ethical challenges that can accompany their work cannot be overlooked. By prioritizing ethical principles, policymakers and program implementers can better ensure that CHWs are combatting HIV through a means that does not exploit or take their critical role within service delivery for granted.

Children diagnosed with type 1 diabetes mellitus (T1DM) are at risk for neurocognitive sequelae, including impaired attention functioning. The specific nature of the cognitive deficit varies; current literature underscores early age of diabetes diagnosis and increased disease duration as primary risk factors for this neurocognitive decline. Forty-three children with T1DM were evaluated for Attention Deficit/Hyperactivity Disorder (ADHD) symptomatology using the MOXO continuous performance test (MOXO-CPT) performed during a routine outpatient evaluation. The study cohort demonstrated a significant decline in all four (...) domains of attention functioning. The effect was most pronounced with early age at T1DM diagnosis, a longer disease duration and with poorer glycemic control (represented by higher HbA1c values). With increased disease duration (of 5 plus years), acute hyperglycemia was associated with inattention in the real-time setting. These findings highlight the need for routine screening of neurocognitive function in children with T1DM so that early intervention can be employed during this crucial period of cognitive development.

This paper explores the tensions that arise when one considers the relevance of institutionalized philosophy to social, political, and environmental change. It considers the time it takes to think deeply, critically, creatively, against the urgent need for protest in the streets, for persuasion of our political representatives, for profound alterations to what we consume. Since philosophy in the academy can reek of disproportionate privilege and self-protection and norms that govern institutionalized philosophy often drive away some of the most curious minds (...) and diverse perspectives, this paper considers: if our philosophical work does not help in substantial ways to address social, political, and environmental crises, can we, in good conscience, continue it? To think through this question, this paper will share a video-based assignment on “activism” that helps me, and hopefully students in my classes, navigate, but not resolve, this tension. (shrink)

The profession of psychology is one of many entities affected by the current economic recession. The question of what to do when clients cannot pay agreed-upon charges will need to be answered. Ethical issues related to setting the fee for psychotherapy, insurance coverage, abandonment, pro bono psychotherapy, and lack of resources are addressed in light of the 2002 American Psychological Association's Ethical Principles of Psychologists and Code of Conduct and other relevant literature. The impact of the Mental Health Parity Act (...) on the financial complexities that professionals in psychology now face is also discussed. Several recommendations are made for psychologists, calling them to be proactive in their communities, to be advocates for their clients, and to critically evaluate their financial practices.

I discuss a problem for modal realism raised by John Divers and others. I argue that the problem is real enough but that Divers’ “advanced modalising” solution is inadquate. The problem can only be solved by 1) holding that modal realism is only contingently true, 2) embracing a kind of Meinongianism about ontological commitment, or 3) abandoning the project of “analysing modality”.

Charles Darwin and C. Lloyd Morgan forward two influential principles of cognitive ethological inference that yield conflicting results about the extent of continuity in the cognitive traits of humans and other animals. While these principles have been interpreted as reflecting commitments to different senses of parsimony, in fact, both principles result from the same vera causa inferential strategy, according to which “We ought to admit no more causes of natural things, than such as are both true and sufficient to explain (...) their appearances”. Instead, the conflict stems from Darwin’s and Morgan’s views about the true causes of human psychology. Darwin holds a thoroughly Humean philosophy of the human mind, from which he infers significant continuity between human and animal minds. In contrast, Morgan argues that Humean cognitive mechanisms cannot account for a class of uniquely human behaviors, and therefore, he concludes that there is a significant discontinuity between human and animal cognition. This historical debate is informative for current controversies in comparative psychology. (shrink)

This paper discusses health policy and systems research in complex and rapidly changing contexts. It focuses on ethical issues at stake for researchers working with government policy makers to provide evidence to inform major health systems change at scale, particularly when the dynamic nature of the context and ongoing challenges to the health system can result in unpredictable outcomes. We focus on situations where ‘country ownership’ of HSR is relatively well established and where there is significant involvement of local researchers (...) and close ties and relationships with policy makers are often present. We frame our discussion around two country case studies with which we are familiar, namely China and South Africa and discuss the implications for conducting ‘embedded’ research. We suggest that reflexivity is an important concept for health system researchers who need to think carefully about positionality and their normative stance and to use such reflection to ensure that they can negotiate to retain autonomy, whilst also contributing evidence for health system change. A research process informed by the notion of reflexive practice and iterative learning will require a longitudinal review at key points in the research timeline. Such review should include the convening of a deliberative process and should involve a range of stakeholders, including those most likely to be affected by the intended and unintended consequences of change.

Assessing the success or failure of a work of architecture typically requires determining its function. However, architectural criticism often founders on apparently intractable disputes concerning the 'true' function of particular works. In this essay, I propose that the proper function of an architectural work is a matter of empirical fact, and can be determined by examining the history of the relevant architectural type. I develop this claim by appeal to the so-called 'etiological theory of function'.

Several major breakthroughs in the history of physics have been prompted not by new empirical data but by thought experiments. James Robert Brown and John Norton have developed accounts of how thought experiments can yield such advances. Brown argues that knowledge gained via thought experiments demands a Platonic explanation; thought experiments for Brown are a window into the Platonic realm of the laws of nature. Norton argues that thought experiments are just cleverly disguised inductive or deductive arguments, so no new (...) account of their epistemology is needed. In this paper, I argue that although we do not need to invoke any Platonic insight to explain thought experimentation, Norton’s eliminativist account fails to capture the unique epistemological importance of thought experiments qua thought experiments. I then present my own account, according to which thought experiments are a particular type of inductive inference that is uniquely suited to generate new breakthroughs. (shrink)

Normally this is not how we think material objects work. I, for example, am a material object that is located in multiple places: this place to my left where my left arm is, and this, distinct, place to my right, where my right arm is. But I am only partially located in each place. My left arm is a part of me that fills exactly the place to my left, and my right arm is a distinct part of me that (...) fills exactly the place to my right. I am located in multiple places by virtue of having distinct parts in those places. So entension is not happening to me — I do not entend. (shrink)

I analyze two recent parsimony arguments that have been offered to break the current impasse in the chimpanzee mindreading controversy, the ‘logical problem’ argument from Povinelli, Penn, and Vonk, and Sober's attempt to apply model selection criteria in support of the mindreading hypothesis. I argue that Sober's approach fails to adequately rebut the ‘logical problem’. However, applying model selection criteria to chimpanzees' own mental models of behavior does yield a response to the ‘logical problem’ and reveals an adaptive advantage of (...) mindreading models and a potential solution to a paradox raised by Whiten.

This paper demonstrates how British Quakers, between 1870 and 1914, attempted to understand and debate the issue of vivisection through the lens of the Quaker peace testimony. Drawing on primary source materials, the article argues that these Friends were able to agitate for radical legislative and social change using virtue ethics as their framework. The paper further suggests that the moral parameters of the Quaker testimony for peace expanded briefly in this period to include interspecies as well as intraspecies engagement. (...) Friends accomplished this by arguing that humans could not engage in vivisection—a “moral disease” just like slavery and war—without risking individual and social virtue. Friends were able to call for radical change in society without arguing for ethical egalitarianism. Hierarchy was implicit in their virtue ethic, but this did not hinder their creation of a forward-thinking stance on human-animal relations. (shrink)

In South Africa, disability grant allocation has been under review and tensions are evident in government rhetoric stressing welfare provision on the one hand, and encouraging on the other. This ambiguity is traced down to the level of grant negotiations between doctors and in a psychiatry clinic in Khayelitsha. Here embodies the distress associated with harsh circumstances and is deemed by supplicants as sufficient to secure a grant. The paper illustrates how national discourses influence the presentation and experience of suffering (...) and the way in which doctors mediate diagnoses. The implications of local understandings of for expectations of the post-apartheid state are explored. (shrink)

The probability that the fitter of two alleles will increase in frequency in a population goes up as the product of N (the effective population size) and s (the selection coefficient) increases. Discovering the distribution of values for this product across different alleles in different populations is a very important biological task. However, biologists often use the product Ns to define a different concept; they say that drift “dominates” selection or that drift is “stronger than” selection when Ns is much (...) smaller than some threshold quantity (e.g., ½) and that the reverse is true when Ns is much larger than that threshold. We argue that the question of whether drift dominates selection for a single allele in a single population makes no sense. Selection and drift are causes of evolution, but there is no fact of the matter as to which cause is stronger in the evolution of any given allele. (shrink)

The theory-theory of human uniqueness posits that the capacity to theorize, in a way strongly analogous to theorizing in scientific practice, was a key innovation in the hominid lineage and was responsible for many of our unique cognitive traits. One of the central arguments that its proponents have used to support the claim that animals are not theorists, the logical problem, bears strong similarities to Hempel's theoretician's dilemma, which purports to show that theories are unnecessary. This similarity threatens to undermine (...) both the claim that theorizing serves a unique, adaptive role in human cognition and our ability to test for the presence of theories. I examine two historical responses to the theoretician's dilemma and argue that they open up strategies for experimentally testing for theoretical ability in other animals. (shrink)

I evaluate the plausibility of explanatory elitism, the view that a good scientific explanation of an outcome will show that it was highly probable. I consider an argument from Michael Strevens that elitism is the only view that can account for the historical acceptance of probabilistic theories in physics. I argue that biology provides better test cases for evaluating elitism and conclude that theories in that domain were favored in virtue of conferring correct, and not necessarily high, probabilities on outcomes.

Several recent arguments by philosophers of biology have challenged the traditional view that evolutionary factors, such as drift and selection, are genuine causes of evolutionary outcomes. In the case of drift, advocates of the statistical theory argue that drift is merely the sampling error inherent in the other stochastic processes of evolution and thus denotes a mathematical, rather than causal, feature of populations. This debate has largely centered around one particular model of drift, the Wright–Fisher model, and this has contributed (...) to the plausibility of the statisticalists’ arguments. However, an examination of alternative, predictively inequivalent models shows that drift is a genuine cause that can be manipulated to change population outcomes. This case study illustrates the influence of methodological assumptions on ontological judgments, particularly the pernicious effect of focusing on a particular model at the expense of others and confusing its assumptions and idealizations for true claims about the phenomena being modeled.

The nature of psychoanalysis seems contradictory - deeply personal, subjective and intuitive, yet requiring systematic theory and principles of technique. The objective quality of psychoanalytic knowledge is paradoxically dependent on the personal engagement of the knower with what is known. In The Dove that Returns, The Dove that Vanishes , Michael Parsons explores the tension of this paradox. As they respond to it, and struggle to sustain it creatively, analysts discover their individual identities. The work of outstanding clinicians such (...) as Marion Milner and John Klauber is examined in detail. The reader also encounters oriental martial arts, Greek Tragedy, the landscape painting of John Constable, a Winnicottian theory of creativity and a discussion of the significance of play in psychoanalysis. From such varied topics evolves a deepening apprehension of the nature of the clinical experience. Illustrated throughout with clinical examples, The Dove that Returns, The Dove that Vanishes will prove valuable to those in the field of psychoanalysis, and to those in the arts and humanities who are interested in contemporary psychoanalytic thinking.

It is a well-known fact of mathematical logic, by now developed in considerable detail, that formalized mathematical theories can be ordered by relative interpretability, and the "strength" of a theory is indicated by where it stands in this ordering. Mutual interpretability is an equivalence relation, and what I call an ordering is a partial ordering modulo this equivalence. Of the theories that have been studied, the natural theories belong to a linearly ordered subset of this ordering.

Here is a puzzle from the Stoic, Chrysippus: There was once a man called Dion, who was unfortunate enough to have his foot annihilated. Thereafter, he was known as Theon. Theon is identical to what was left over after Dion’s foot was removed. That is, Theon is that part of Dion that does not include his foot. If all this is true, then Theon is a proper part of Dion. That is, he is a part of Dion, but not identical (...) to Dion. But if that’s right, then, surprisingly, Dion didn’t survive the loss of his foot. (shrink)

This book deals with the need to rethink the aims and methods of contemporary linguistics. Orthodox linguists' discussions of linguistic form fail to exemplify how language users become language makers. Integrationist theory is used here as a solution to this basic problem within general linguistics. The book is aimed at an interdisciplinary readership, comprising those engaged in study, teaching and research in the humanities and social sciences, including linguistics, philosophy, sociology and psychology.

In their 2010 book, Biology’s First Law, D. McShea and R. Brandon present a principle that they call ‘‘ZFEL,’’ the zero force evolutionary law. ZFEL says (roughly) that when there are no evolutionary forces acting on a population, the population’s complexity (i.e., how diverse its member organisms are) will increase. Here we develop criticisms of ZFEL and describe a different law of evolution; it says that diversity and complexity do not change when there are no evolutionary causes.
