Delusions have traditionally been considered the hallmark of mental illness, and their conception, diagnosis and treatment raise many of the fundamental conceptual and practical questions of psychopathology. One of these fundamental questions is whether delusions are understandable. In this paper, we propose to consider the question of understandability of delusions from a philosophy of language perspective. For this purpose, we frame the question of how delusions can be understood as a question about the meaning of delusional utterances. Accordingly, we ask: (...) “what meaning(s) can delusional utterances possibly have?”. We argue that in the current literature, there is a standard approach to the meaning of delusional utterances, namely the descriptive account which assumes that a delusional utterance “p” means that p is the case. Drawing on Speech Act Theory, we argue that solely relying on the descriptive account disregards essential ways of how linguistic meaning is constituted. Further, we show that Speech Act Theory can prove a helpful addition to the theoretical and clinical “toolbox” used for attempting to understand delusional utterances. This, we believe, may address some of the theoretical and clinical shortcomings of using only the currently predominant descriptive account. (shrink)

Permissivism is the thesis that, for some body of evidence and a proposition p, there is more than one rational doxastic attitude any agent with that evidence can take toward p. Proponents of uniqueness deny permissivism, maintaining that every body of evidence always determines a single rational doxastic attitude. In this paper, we explore the debate between permissivism and uniqueness about evidence, outlining some of the major arguments on each side. We then consider how permissivism can be understood as an (...) underdetermination thesis, and show how this moves the debate forward in fruitful ways: in distinguishing between different types of permissivism, in dispelling classic objections to permissivism, and in shedding light on the relationship between permissivism and evidentialism.

Creationists who object to evolution in the science curriculum of public schools often cite Jonathan Well’s book Icons of Evolution in their support (Wells 2000). In the third chapter of his book Wells claims that neither paleontological nor molecular evidence supports the thesis that the history of life is an evolutionary process of descent from preexisting ancestors. We argue that Wells inappropriately relies upon ambiguities inherent in the term ‘Darwinian’ and the phrase ‘Darwin’s theory’. Furthermore, he does not accurately distinguish (...) between the overwhelming evidence that supports the thesis of common descent and controversies that pertain to causal mechanisms such as natural selection. We also argue that Wells’ attempts to undermine the evidence in support of common descent are flawed and his characterization of the relevant data is misleading. In particular, his assessment of the ‘Cambrian explosion’ does not do justice to the fossil record. Nor do his selective references to debate about molecular and paleontological phylogenies constitute a case against common descent. We conclude that the fossil and molecular evidence is more than sufficient to warrant science educators to present common descent as a well-established scientific fact. We also argue that diagrams depicting the ‘tree of life’ can be pedagogically useful as simplified representations of the history of life. (shrink)

Theological synthesis of religious doctrine with evolutionary science is commonly referred to as theistic evolution. The influential Thomistic school of theology has played a complex role in Catholic contributions to this subject. In the present essay I explore this historical legacy and take stock of recent Thomistic contributions to theistic evolution. I also highlight some unresolved issues, particularly those associated with the concept of substantial form. I conclude that theistic evolution within a Thomistic framework is a potentially more promising agenda (...) for Catholic theology than an incorporation of intelligent design and progressive creation.

Darcy's law is a phenomenological relationship for fluid flow rate that finds one of its principle applications in hydrology. Theoretical hydrologists rely upon a multiplicity of conceptual models to carry out approximate derivations of Darcy's law. These derivations provide structural explanations of the law; they require the application of fundamental principles, such as conservation of momentum, to idealized models of the porous media within which the flow occurs. In practice, recognition of the idealized conditions incorporated into models facilitates the empirical (...) clarification of the domain within which the law remains accurate. Structural explanations also contribute to the physical interpretation of phenomenological parameters. (shrink)

There has been a significant increase in the use of radiological services in the past 30 years. There are many reasons for this, but one has received little attention: the increased role of patient autonomy in healthcare. Patients demand x rays, CT scans, MRI, and positron emission tomography scans. The key question in this article is how a moral principle, such as respect for patient autonomy, can influence the extension of radiological services. A literature review reveals how patient autonomy is (...) acknowledged in radiology, and how it is used both to explain and to justify the increase in radiological examinations. Furthermore, it also shows how the premises favouring patients’ exercise of their autonomy are not always present, which makes patient autonomy subject to adverse side effects and even abuse. Patient autonomy can be used to reduce the professionals’ responsibility for radiological examinations , to increase the popularity of the profession , to increase the income of the professionals or their institutions, and to promote professional activity. Patient autonomy intended to reduce paternalism, to legitimise otherwise morally unjustifiable actions , and to protect patients, can easily be used as a moral means for opposite ends. These adverse effects are not peculiar to radiology. However, they emerge particularly clearly in explanations and justifications of the substantial increase in radiological services, as well as in debates on overuse of radiological services. (shrink)

In discussions of religious disagreement, some epistemologists have suggested that religious disagreement is distinctive. More specifically, they have argued that religious disagreement has certain features which make it possible for theists to resist conciliatory arguments that they must adjust their religious beliefs in response to finding that peers disagree with them. I consider what I take to be the two most prominent features which are claimed to make religious disagreement distinct: religious evidence and evaluative standards in religious contexts. I argue (...) that these two features fail to distinguish religious disagreement in the ways they have been taken to. However, I show that the view that religious disagreement is not a unique form of disagreement makes religious disagreement less, rather than more, worrisome to the theist who would prefer to rationally remain steadfast in her religious beliefs.

We provide a novel defense of the possibility of level-splitting beliefs and use this defense to show that the steadfast response to peer disagreement is not, as it is often claimed to be, unnecessarily dogmatic. To provide this defense, a neglected form of moral disagreement is analysed. Within the context of this particular kind of moral disagreement, a similarly neglected form of level-splitting belief is identified and then defended from critics of the rationality of level-splitting beliefs. The chapter concludes by (...) showing that proponents of the steadfast response to peer disagreement can adopt this form of level-splitting belief in the context of these moral disagreements while exemplifying intellectual humility, rather than dogmatism.

Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical. For example, human cytochrome c differs from that of an alligator by 13 amino acids but differs by 14 amino acids from a much more closely related primate, Otolemur garnettii. The apparent anomaly is resolved by taking into consideration the variable substitution rate of cytochrome (...) c, particularly among primates. This paper traces some of the history of extensive research into the topic of rate heterogeneity in cytochrome c including data from cytochrome c pseudogenes. (shrink)

Most philosophical discussions of disagreement have used idealized disagreements to draw conclusions about the nature of disagreement. I closely examine an actual, non-idealized disagreement in dinosaur paleobiology and show that it can not only teach us about the features of some of our real world disagreements, but can help us to argue for the possibility of reasonable real world disagreement.

Building upon Nancy Cartwright's discussion of models in How the Laws of Physics Lie, this paper addresses solid state research in transition metal oxides. Historical analysis reveals that in this domain models function both as the culmination of phenomenology and the commencement of theoretical explanation. Those solid state chemists who concentrate on the description of phenomena pertinent to specific elements or compounds assess models according to different standards than those who seek explanation grounded in approximate applications of the Schroedinger equation. (...) Accurate accounts of scientific debate in this field must include both perspectives. (shrink)

I provide a critical review of Moti Mizrahi's The Relativity of Theory, expounding on the book's strengths and then providing an extended argument that Mizrahi mischaracterizes the epistemic attitude of concern to antirealism about science as well as the practical stakes involved in adopting the antirealist position.

As it emerged from philosophical analyses and cognitive research, most concepts exhibit typicality effects, and resist to the efforts of defining them in terms of necessary and sufficient conditions. This holds also in the case of many medical concepts. This is a problem for the design of computer science ontologies, since knowledge representation formalisms commonly adopted in this field (such as, in the first place, the Web Ontology Language - OWL) do not allow for the representation of concepts in terms (...) of typical traits. The need of representing concepts in terms of typical traits concerns almost every domain of real world knowledge, including medical domains. In particular, in this article we take into account the domain of mental disorders, starting from the DSM-5 descriptions of some specific disorders. We favour a hybrid approach to concept representation, in which ontology oriented formalisms are combined to a geometric representation of knowledge based on conceptual space. As a preliminary step to apply our proposal to mental disorder concepts, we started to develop an OWL ontology of the schizophrenia spectrum, which is as close as possible to the DSM-5 descriptions.

Driven by the use cases of PubChemRDF and SCAIView, we have developed a first community-based clinical trial ontology (CTO) by following the OBO Foundry principles. CTO uses the Basic Formal Ontology (BFO) as the top level ontology and reuses many terms from existing ontologies. CTO has also defined many clinical trial-specific terms. The general CTO design pattern is based on the PICO framework together with two applications. First, the PubChemRDF use case demonstrates how a drug Gleevec is linked to multiple (...) clinical trials investigating Gleevec’s related chemical compounds. Second, the SCAIView text mining engine shows how the use of CTO terms in its search algorithm can identify publications referring to COVID-19-related clinical trials. Future opportunities and challenges are discussed. (shrink)

In this paper, I respond to Frank Hofmann’s reply to my (2022) argument against “evidential minimalism” (EM). According to defenders of EM, there is a close connection between evidence and normative reasons for belief: evidence is either itself, or (under certain “minimal” conditions) gives rise to, a normative reason for belief. In my (2022), I argued against EM by showing that there are cases where: (i) S possesses strong evidence E for the truth of p at time t, (ii) (...) all minimal conditions for the normativity of E are met at t, (iii) S doesn’t believe p at t, yet (iv) S isn’t criticizable on account of (i)-(iii) at t. I then appealed to a linking claim connecting criticizability with the existence of normative reasons for belief. Hofmann’s reply invokes a distinction between two different kinds of epistemic criticism: a strong and a weak form. I will argue that Hofmann’s distinction fails to save EM from my argument.

This paper explores relationships between environment and education after the Covid-19 pandemic through the lens of philosophy of education in a new key developed by Michael Peters and the Philosophy of Education Society of Australasia. The paper is collectively written by 15 authors who responded to the question: Who remembers Greta Thunberg? Their answers are classified into four main themes and corresponding sections. The first section, ‘As we bake the earth, let's try and bake it from scratch’, gathers wider (...) philosophical considerations about the intersection between environment, education, and the pandemic. The second section, ‘Bump in the road or a catalyst for structural change?’, looks more closely into issues pertaining to education. The third section, ‘If you choose to fail us, we will never forgive you’, focuses to Greta Thunberg’s messages and their responses. The last section, ‘Towards a new normal’, explores future scenarios and develops recommendations for critical emancipatory action. The concluding part brings these insights together, showing that resulting synergy between the answers offers much more then the sum of articles’ parts. With its ethos of collectivity, interconnectedness, and solidarity, philosophy of education in a new key is a crucial tool for development of post-pandemic education. (shrink)

Since the stone age humankind has created masterworks which possess a mysterious quality of solidity and grandeur or monumentality. A Paleolithic Venus and a still life by Cezanne both share this monumentality. Michelangelo likened monumentality to sculptural relief, Braque called monumentality 'space', and Hans Hoffman, himself one of the masters, called monumentality 'pictorial depth.' The masters agreed on the import of monumentality, but none of them left a clear explanation of it. In 1943 Earl Loran published his classic book on (...) Cezanne's pictorial structure but, as I demonstrate, his explanation was misleading. This book provide a clear explanation, as did an earlier book by Robert Casper. This book also traces some history of monumentality with reproductions. It also explains how some painters achieved monumentality and how a student can attempt it. Pictorial space is created in the tension between pairs of opposing planes. Opposing planes pull against each other, each containing the other, paradoxically, within the flat surface of the canvas. Sculpture also can be 'plastic': opposing masses pull against each other, each containing the other and creating tension in the space which lies between them. Painting has other aspects like subject matter, expression, style and technique but pictorial space does not depend on these. Monumentality moves us profoundly and apparently has done so since the Paleolith. Using patients' vignettes, I show that there are profound parallels between the structure of a monumental work of art and the structure of an evolving personality. In Winnicott's words, such a personality has 'depth ... an interior space to put beliefs in ... an inside ... a space where things can be held ... the capacity to accept paradox [to contain opposites] ... room and strength ... and originality and the acceptance of tradition as the basis for invention'. A monumental painting also meets this description. I argue that monumental art provides a visual portrait of an evolving personality just as myth, as Freud and Jung both showed, provides a narrative portrait of an evolving personality. An evolving personality is perhaps humankind's most important creation; an underlying purpose of both myth and art is to help us achieve it. I demonstrate in this book that monumental art represented the evolving personality since at least 35,000 BC. Thus to understand monumentality is to better understand the personality and its history.

Greta Thunberg has rapidly become a household name due to her passionate involvement in the youth climate movement. However, Thunberg has also received criticism, among other things for her anger. Is such anger really productive, people ask, or is it harming the cause of climate justice? In this article, I examine that question from a philosophical perspective. I look at two commonly mentioned disadvantages of anger, namely that it is a retributive emotion and that it reduces uptake of one’s (...) message, and I provide some reasons why these might not be disadvantageous after all. Then, I look at four different advantages of anger: its motivational power, its revolutionary potential, its use for community building, and its epistemic value. Each of these points is linked back to the climate movement as it is personified by Greta Thunberg, in order to analyse the anger that is at times very prominent in her activist message. While a definite conclusion about the productivity of Thunberg’s anger is difficult to reach, I conclude that her anger should be listened to regardless, since we have much to learn from it.

I’m grateful to Aleta Quinn and Studies in History and Philosophy of Science for hosting this book forum for my book, The Relativity of Theory (Springer, 2020). I’m also grateful to Margaret Greta Turnbull and Joseph Martin for their commentaries. In what follows, I address their comments as I understand them.

Kant was well versed in many of the debates taking place in the life sciences during his day. One of the more central areas of contention concerned the proper means for discriminating between material bodies composed of organised parts (like clocks or automatons) and living material bodies composed of organised parts (like plants and animals). For many theorists, it seemed clear that the physically organised structure of a body was distinct from any vital forces responsible for the life processes or (...) metabolism at work within it. This was the approach taken by the chemist Georg Stahl (1659-1734), for example, who resisted attempts to provide a mechanical account of metabolism, arguing instead that only something like a physis or anima could explain a living body’s capacity for the movement of otherwise inert material parts. This was a position which Kant appears to have appreciated when, in discussing the issue in 1766, he exclaimed “I am convinced that Stahl, who is disposed to explain animal processes in organic terms, was frequently closer to the truth than [the mechanists] Hofmann or Boerhaave, to name but a few” (2:331). And indeed, by 1790 Kant would reach conclusions similar to Stahl’s regarding the manner by which we must reflectively judge animal processes to be operating, given that for Stahl the biological body was best taken to be a complex, self-organising system of material parts and a purposive force or physis responsible for their ongoing interrelation.

Humans face wide ranging and global challenges in the Anthropocene, the most prominent of which is anthropogenic climate change. One initial pivot towards sustainability, particularly in my home country of the United States, has been to rely heavily on technological innovation powered most obviously by engineers. Using the climate activist Greta Thunberg's speech at the 2018 United Nations Climate Change Conference as my inspiration, I try to show how some of the technology based solutions only entrench what I call (...) the “Bestance” mentality, that is, the fundamental stance or orientation toward the natural world in the Anthropocene wherein all entities show up as mere resources. Upon showing the various ways in which traditional ethical approaches and environmental philosophical approaches have proved unhelpful in navigating the challenges of the Anthropocene, I try to demonstrate and how a Heideggerian ecophenomenological approach can help us not only understand how the world appears to many of us in the Anthropocene, but also what a more graceful way of being might look like in Heidegger's concept of “dwelling.” Using specific examples of current technologies pervasively normalized in the United States, including hydraulic fracturing, horizontal drilling, desalination, and artificial nitrogen based fertilization, I use Heidegger's philosophical concepts to show how the land, sea, and air can show up as Bestand in the Anthropocene, that is, merely materials on hand to be manipulated in order to serve human interests.

A political philosopher dissects the duties and dilemmas of the unelected spokesperson, from Martin Luther King, Jr., to Greta Thunberg. -/- Political representation is typically assumed to be the purview of formal institutions and elected officials. But many of the people who represent us are not senators or city councilors—think of Martin Luther King, Jr., or Malala Yousafzai or even a neighbor who speaks up at a school board meeting. Informal political representatives are in fact ubiquitous, often powerful, and (...) some bear enormous responsibility. In Speaking for Others, political philosopher Wendy Salkin develops the first systematic conceptual and moral analysis of informal political representation. -/- Salkin argues that informal representation can be a political lifeline, particularly for oppressed and marginalized groups that are denied representation in formal political institutions. Yet informal political representatives exert outsized influence over the ways these groups’ interests are understood by the public, without the represented having much recourse to hold them accountable. And many informal political representatives are selected not by the groups they represent but by outsiders, sticking these groups with representatives they would not choose but cannot shake. The role of informal political representatives is therefore fraught with moral questions. What exactly are their duties and to whom are they owed? Should they be members of the groups they represent? When is informal representation permissible and when is it best avoided? -/- Informal political representation is taking place all around us. In fact, you yourself may be an informal political representative without knowing it. Speaking for Others explores the tensions central to this pervasive yet underexamined practice, bringing light to both its perils and its promise. (shrink)
