Modal Platonism utilizes "weak" logical possibility, such that it is logically possible there are abstract entities, and logically possible there are none. Modal Platonism also utilizes a non-indexical actuality operator. Modal Platonism is the EASY WAY, neither reductionist nor eliminativist, but embracing the Platonistic language of abstract entities while eliminating ontological commitment to them. Statement of Modal Platonism. Any consistent statement B ontologically committed to abstract entities may be replaced by an empirically equivalent modalization, MOD(B), not so ontologically committed. This (...) equivalence is provable using Modal/Actuality Logic S5@. Let MAX be a strong set theory with individuals. Then the following Schematic Bombshell Result (SBR) can be shown: MAX logically yields [T is true if and only if MOD(T) is true], for scientific theories T. The proof utilizes Stephen Neale's clever model-theoretic interpretation of Quantified Lewis S5, which I extend to S5@. (shrink)

. In this paper, I attempt to dissolve the theism/atheism boundary. In the first part, I consider last things, according to mainstream science. In the second part, I define the Natural God as the Force of Nature—evolving, unifying, maximizing—and consider Its relation to last things. Finally, I discuss our knowledge of the Natural God and Its relevance to our personal lives. I argue that we can know the Natural God through scientific reason combined with global intuition, and that this knowledge, (...) from the perspective of last things, may help us achieve universal love, ethical action, and personal salvation.

This is a complete exposition of a tight version of a fundamental theorem of computational complexity due to Levin: The inherent space complexity of any partial function is very accurately specifiable in a Π1 way, and every such specification that is even Σ2 does characterize the complexity of some partial function, even one that assumes only the values 0 and 1.

In spite of the work of Gödel and Cohen, which showed the undecidability of the Generalized Continuum Hypothesis from the axioms of set theory, the problem still remains to decide GCH on the basis of new axioms. It is almost 100 years since Cantor first conjectured the Continuum Hypothesis, yet we seem to be no closer to determining its truth. Nevertheless, it is a sound methodological principle that given any undecidable set-theoretical statement, we should search for “other axioms of set (...) theory which a more profound understanding of the concepts underlying logic and mathematics would enable us to recognize as implied by these concepts”.

El conjunto de ensayos que el lector tiene entre sus manos expresa un cuerpo sistemático de ideas provocadoras sobre la tensión entre el constitucionalismo y la democracia. Su autor, el profesor Joel Colón-Ríos, boricua, formado en las dos facultades de derecho canadienses de mayor renombre, e investigador de una de las mejores universidades de Oceanía, las ha fraguado a lo largo de más de un lustro y debatido con gran éxito ante la elite intelectual de Norteamérica. La propuesta central (...) del libro es una original reivindicación de la democracia frente al constitucionalismo. Su institucionalización consiste en un constitucionalismo débil. La piedra angular de este modelo es una constitución inacabada, permanentemente abierta al cambio, que permite y promueve la participación y la deliberación popular continua, en particular, mediante el potencial ejercicio del poder constituyente en cualquier momento. De esta manera, el pueblo tiene la posibilidad de hablar por sí mismo cuando lo juzgue pertinente. Puede cuestionar y reformular los principios básicos de la organización social. No está supeditado a las decisiones adoptadas por los ancestros que expidieron la Constitución, ni por sus representantes que, en el Congreso, ostentan el poder de reformarla. Precio: 49.000 pesos.

Rousseau has always had an uncertain relationship with the theory of constituent power. On the one hand, his distrust of political representation and support for popular sovereignty seem consistent with the idea of the people as a legally unlimited constitution-maker. On the other hand, if, from those views about representation and sovereignty, it follows that Rousseau is a proponent of direct democracy, then there seems to be no place in his thought for a theory that presupposes, above all, a separation (...) between those who exercise a delegated authority and those who possess an original constitution-making power. In a legal order in which all laws must be directly made by the people, such a separation is absent: the constituent and the legislative body are one and the same. It is therefore not surprising that Rousseau’s name is largely absent from contemporary literature on constituent power. In this article, however, I will show that once Rousseau’s particular conception of law, as well as his distinction between sovereignty and government, are properly understood, one finds in his work not only the first major formulation of the theory of constituent power, but also a careful exploration of its implications for actual constitutional practice.

In Coogan's Bluff (1968) and the Dirty Harry films, Clint Eastwood's characters often invoke luck when they want unpredictable others to assume some responsibility to stop violence, thereby implicating moral luck in heroism. In the famous ‘Do I feel lucky’ scene from Dirty Harry (1971), Eastwood's character might not be bluffing, but he is giving luck a role in justice. In this case and others, his character's unconventional responsibility should prompt reconsideration of his character's virtue. Viewers must also decide where (...) the deceptive or rule-breaking policeman locates the responsibility for his actions. (shrink)

How can intuitions be used to validate or invalidate a philosophical theory? An intuition about a case seems to be a basic evidential source for the truth of that intuition, i.e., for the truth of the claim that a particular example is or isn’t an instance of a philosophically interesting kind, concept, or predicate. A mental‐state type is a basic evidential source only if its tokens reliably indicate the truth of their contents. The best way to account for intuitions being (...) a basic evidential source is to interpret their subject matter in psychologistic terms. Intuitions provide evidence about the contents of the intuiter's concept, where “concept” is understood as a psychological structure. (shrink)

There is growing philosophical interest in “affective injustice”: injustice faced by individuals specifically in their capacity as affective beings. Current debates tend to focus on affective injustice at the psychological level. In this paper, I argue that the built environment can be a vehicle for affective injustice — specifically, what Wildman et al. (2022) term “affective powerlessness”. I use resources from ecological psychology to develop this claim. I consider two cases where certain kinds of bodies are, either intentionally or unintentionally, (...) deprived of access to goods affording the development and maintenance of their subjective well-being: hostile architecture and masking practices in autism. This deprivation, I argue further, leads to a significant weakening and diminishment of their spatial agency, hinders their well-being, and in so doing gives rise to a pervasive experience of affective powerlessness. By drawing attention to these themes, I show that an ecological approach helpfully supplements existing approaches. It highlights how affective injustice can emerge via the way bodies are positioned in space, and the central role that built environments play in determining this positioning. (shrink)

I offer a preliminary defense of the hypothesis of extended emotions (HEE). After discussing some taxonomic considerations, I specify two ways of parsing HEE: the hypothesis of bodily extended emotions (HEBE), and the hypothesis of environmentally extended emotions (HEEE). I argue that, while both HEBE and HEEE are empirically plausible, only HEEE covers instances of genuinely extended emotions. After introducing some further distinctions, I support one form of HEEE by appealing to different streams of empirical research—particularly work on music and (...) emotion regulation. However, I register skepticism about a second and more radical form of HEEE. (shrink)

Grief is, and has always been, technologically supported. From memorials and shrines to photos and saved voicemail messages, we engage with the dead through the technologies available to us. As our technologies evolve, so does how we grieve. In this paper, we consider the role chatbots might play in our grieving practices. Influenced by recent phenomenological work, we begin by thinking about the character of grief. Next, we consider work on developing “continuing bonds” with the dead. We argue that for (...) some, chatbots may play an important role in establishing these continuing bonds by helping us develop what we term “habits of intimacy”. We then turn to the “ick factor” some may feel about this prospect, focusing especially on ethical concerns raised by Patrick Stokes and Adam Buben about the risk of replacing our dead with chatbots. We argue that replacement worries are not as pressing as Stokes and Buben suggest. We resist these replacement worries by appealing to the “thin reciprocity”, as we refer to it, that such bots offer, as well as the fictionalist stance that we think users of the bots adopt when engaging with them. We conclude by briefly raising some additional concerns and highlighting future research questions. (shrink)

I use critical phenomenological resources in Tetsurō Watsuji and Sarah Ahmed to explore the spatial origin of some social impairments in Autistic Spectrum Disorder (ASD). I argue that a critical phenomenological perspective puts pressure on the idea that social impairments in ASD are exclusively (or even primarily) neurocognitive deficits that can be addressed by focusing on cognitive factors internal to the autistic person — for example, training them to adopt a more neurotypical approach to social cognition. Instead, I argue that (...) the structure and character of some neurotypical spaces may play a regulative role in shaping aspects of at least some of the social impairments autistic people exhibit when they inhabit these spaces. I also briefly consider some possible therapeutic applications of this critical phenomenological approach. (shrink)

Drawing upon the life and work of S. Kay Toombs, I explore the impact and import of phenomenological accounts of disability for the existentialist tradition. Through the case of multiple sclerosis, a noncongenital, late-onset, and degenerative disability, I show how the general structures that emerge from its lived experience largely support a mere-difference view of disability and highlight the need for an equitably habitable world. I further argue that phenomenological accounts of disability demonstrate accessibility to be the defining feature of (...) what it means to be embodied as we are. I conclude with a discussion of the more general philosophical relationship between disability, embodiment, and existentialism. (shrink)

I bring out the limitations of four important views of what the target of useful climate model assessment is. Three of these views are drawn from philosophy. They include the views of Elisabeth Lloyd and Wendy Parker, and an application of Bayesian confirmation theory. The fourth view I criticise is based on the actual practice of climate model assessment. In bringing out the limitations of these four views, I argue that an approach to climate model assessment that neither demands too (...) much of such assessment nor threatens to be unreliable will, in typical cases, have to aim at something other than the confirmation of claims about how the climate system actually is. This means, I suggest, that the Intergovernmental Panel on Climate Change ’s focus on establishing confidence in climate model explanations and predictions is misguided. So too, it means that standard epistemologies of science with pretensions to generality, e.g., Bayesian epistemologies, fail to illuminate the assessment of climate models. I go on to outline a view that neither demands too much nor threatens to be unreliable, a view according to which useful climate model assessment typically aims to show that certain climatic scenarios are real possibilities and, when the scenarios are determined to be real possibilities, partially to determine how remote they are.

Although enactive approaches to cognition vary in terms of their character and scope, all endorse several core claims. The first is that cognition is tied to action. The second is that cognition is composed of more than just in-the-head processes; cognitive activities are externalized via features of our embodiment and in our ecological dealings with the people and things around us. I appeal to these two enactive claims to consider a view called “direct social perception” : the idea that we (...) can sometimes perceive features of other minds directly in the character of their embodiment and environmental interactions. I argue that if DSP is true, we can probably also perceive certain features of mental disorders as well. I draw upon the developmental psychologist Daniel Stern’s notion of “forms of vitality”—largely overlooked in these debates—to develop this idea, and I use autism as a case study. I argue further that an enactive approach to DSP can clarify some ways we play a regulative role in shaping the temporal and phenomenal character of the disorder in question, and it may therefore have practical significance for both the clinical and therapeutic encounter.

Affordances are action-possibilities, ways of relating to and acting on things in our world. They help us understand how these things mean what they do and how we have bodily access to our world more generally. But what happens when this access is ruptured or impeded? I consider this question in the context of psychopathology and reports that describe this experience. I argue that thinking about the bodily consequences of losing access to everyday affordances can help us better understand these (...) reports. An affordance-based approach to psychopathology can illuminate some of the causes, as well as the experiential character and consequences, of affective disorders and diminished spatial agency in self-world disturbances. It also highlights some under-explored ethical and political dimensions of these issues that need further attention. (shrink)

Loneliness is a near-universal experience. It is particularly common for individuals with (so-called) psychopathological conditions or disorders. In this paper, we explore the experiential character of loneliness, with a specific emphasis on how social goods are experienced as absent in ways that involve a diminished sense of agency and recognition. We explore the role and experience of loneliness in three case studies: depression, anorexia nervosa, and autism. We demonstrate that even though experiences of loneliness might be common to many psychopathologies, (...) these experiences nevertheless have distinctive profiles. Specifically, we suggest that: (i) loneliness is often a core characteristic of depressive experience; (ii) loneliness can drive, and even cement, disordered eating practices and anorectic identity in anorexia nervosa; iii) loneliness is neither a core characteristic of autism nor a driver but is rather commonly experienced as stemming from social worlds, environments, and norms that fail to accommodate autistic bodies and their distinctive forms of life. We aim to do justice to the pervasiveness of loneliness in many — if not all — psychopathologies, while also highlighting the need to attend to psychopathology-specific experiences of loneliness, agency, and (non-)recognition.

I outline the theoretical framework of, and three research programs within American speculative philosophy of science during the period 1900-1931. One program applies verificationism to research in psychology, one investigates the methodology of research programs, and one analyses scientific explanation and other scientific concepts. The primary sources for my outline are works by Morris Raphael Cohen, Grace Andrus de Laguna, Theodore de Laguna, Edgar Arthur Singer Jr., Harold Robert Smart, and Marie Collins Swabey. I also use my outline to provide (...) a partial comparison of American speculative philosophy of science and 1930s logical positivism. My comparison suggests that logical positivism was a proposal for substantially narrowing down and winding back American philosophy of science and was based on positions that were already problematized in the American context. -/- .

Grace A. de Laguna was an American philosopher of exceptional originality. Many of the arguments and positions she developed during the early decades of the twentieth century later came to be central to analytic philosophy. These arguments and positions included, even before 1930, a critique of the analytic-synthetic distinction, a private language argument, a critique of type physicalism, a functionalist theory of mind, a critique of scientific reductionism, a methodology of research programs in science and more. Nevertheless, de Laguna identified (...) herself as a defender of the speculative vision of philosophy, a vision which, in her words, “analytic philosophy condemns.” I outline her speculative vision of philosophy as well as what is, in effect, an argument she offers against analytic philosophy. This is an argument against the view that key parts of established opinion, e.g., our best theoretical physics or most certain common sense, should be assumed to be true in order to answer philosophical questions. I go on to bring out the implications of her argument for the approaches to philosophy of Bertrand Russell, Willard V. Quine and David Lewis, and I also compare the argument to recent, related arguments against analytic philosophy. I will suggest that de Laguna offers a viable critique of analytic philosophy and an alternative approach to philosophy that meets this critique. (shrink)

I develop Tetsurō Watsuji’s relational model of the self as “betweenness”. I argue that Watsuji’s view receives support from two case studies: solitary confinement and dementia. Both clarify the constitutive interdependence between the self and the social and material contexts of “betweenness” that define its lifeworld. They do so by providing powerful examples of what happens when the support and regulative grounding of this lifeworld is restricted or taken away. I argue further that Watsuji’s view helps see the other side (...) of this deprivation, how reconstructing aspects of betweenness is, at the same time, a reconstruction of the self. I conclude by briefly indicating further consequences of this view. (shrink)

Ethical extensionism is a common argument pattern in environmental and animal ethics, which takes a morally valuable trait already recognized in us and argues that we should recognize that value in other entities such as nonhuman animals. I exposit ethical extensionism’s core argument, argue for its validity and soundness, and trace its history to 18th century progressivist calls to expand the moral community and legal franchise. However, ethical extensionism has its critics. The bulk of the paper responds to recent criticisms, (...) including (1) environmental ethicists’ objection against its austere conception of moral value (2), feminist ethicists’ claim that extensionism fails to account for the moral significance of difference, (3) disability theorists’ concern that ethical extensionist arguments are offensive, and (4) animal rights theorists’ lament that extensionism is a practical failure. While something is to be gained from each criticism, I argue that they ultimately fail and that extensionism remains compelling. (shrink)

Katzav and Vaesen have argued that control by analytic philosophers of key journals, philosophy departments and at least one funding body plays a substantial role in explaining the emergence of analytic philosophy into dominance in the Anglophone world and the corresponding decline of speculative philosophy. They also argued that this use of control suggests a characterisation of analytic philosophy as, at the institutional level, a sectarian form of critical philosophy. I test these hypotheses against data about philosophy job hires at (...) key philosophy departments in the USA during the period 1930-1979, and against data about PhD completions during the period 1956-1965. I argue, further, that Katzav and Vaesen’s hypotheses can fully explain the data and are more fully able to do so than are some other key accounts of the emergence of analytic philosophy in the USA.

According to the realist interpretation, measurement commits us not just to the logically independent existence of things in space and time, but also to the existence of quantitatively structured properties and relations, and to the existence of real numbers, understood as relations of ratio between specific levels of such attributes. Measurement is defined as the estimation of numerical relations (or ratios) between magnitudes of a quantitative attribute and a unit. The history of scientific measurement, from antiquity to the present may (...) be interpreted as revealing a progressive deepening in the understanding of this position. First, the concept of ratio was broadened to include ratios between incommensurable magnitudes; second, the concept of a quantitative attribute was broadened to include non-extensive quantities; third, quantitative structure and its relations to ratios and real numbers were elaborated; and finally, the issue of empirically distinguishing between quantitative and non-quantitative structures was addressed. This interpretation of measurement understands it in a way that is continuous with scientific investigation in general, i.e., as an attempt to discover independently existing facts. (shrink)

I revisit my paper, ‘Grace de Laguna’s 1909 Critique of Analytic Philosophy’ and respond to the commentary on it. I respond to James Chase and Jack Reynolds by further analysing the difference between speculative philosophy as de Laguna conceived of it and analytic philosophy, by clarifying how her critique of analytic philosophy remains relevant to some of its more speculative forms, and by explaining what justifies the criticism of established opinion that goes along with her rejection of analytic philosophy’s epistemic (...) conservatism. In response to Andreas Vrahimis, I contextualise my reading of de Laguna’s work in 1909. This clarifies her critique of pragmatism, distinguishes it from her critique of epistemically conservative philosophy, and shows that she was not only already aware of the full scope of the latter critique but is likely to have identified the then incipient analytic philosophy as its primary target. Also, contra Vrahimis, her argument is effective against Bertrand Russell’s later, epistemically conservative approach to philosophy. In response to Cheryl Misak, I point out that her argument that de Laguna is, despite herself, a pragmatist rests on a misunderstanding of the differences between pragmatism and idealism, and I show that de Laguna’s main early influences were Herbert Spencer and her teacher, James Edwin Creighton. I further argue that Misak’s rejection of de Laguna’s critique of pragmatism rests on a misrepresentation of the critique. (shrink)

Despite being assailed for decades by disability activists and disability studies scholars spanning the humanities and social sciences, the medical model of disability—which conceptualizes disability as an individual tragedy or misfortune due to genetic or environmental insult—still today structures many cases of patient–practitioner communication. Synthesizing and recasting work done across critical disability studies and philosophy of disability, I argue that the reason the medical model of disability remains so gallingly entrenched is due to what I call the “ableist conflation” of (...) disability with pain and suffering. In an effort to better equip healthcare practitioners and those invested in health communication to challenge disability stigma, discrimination, and oppression, I lay out the logic of the ableist conflation and interrogate examples of its use. I argue that insofar as the semiosis of pain and suffering is structured by the lived experience of unwelcome bodily transition or variation, experiences of pain inform the ableist conflation by preemptively tying such variability and its attendant disequilibrium to disability. I conclude by discussing how philosophy of disability and critical disability studies might better inform health communication concerning disability, offering a number of conceptual distinctions toward that end.

Self-disorders in depression and schizophrenia have been the focus of much recent work in phenomenological psychopathology. But little has been said about the role the material environment plays in shaping the affective character of these disorders. In this paper, we argue that enjoying reliable (i.e., trustworthy) access to the things and spaces around us — the constituents of our material environment — is crucial for our ability to stabilize and regulate our affective life on a day-today basis. These things and (...) spaces often play an ineliminable role in shaping what we feel and how we feel it; when we interact with them, they contribute ongoing feedback that " scaffolds " the character and temporal development of our affective experiences. However, in some psychopathological conditions, the ability to access to these things and spaces becomes disturbed. Individuals not only lose certain forms of access to the practical significance of the built environment but also to its ​ regulative​ significance, too — and the stability and organization of their affective life is compromised. In developing this view, we discuss core concepts like " affordance spaces " , " scaffolding " , and " incorporation ". We apply these concepts to two case studies, severe depression and schizophrenia, and we show why these cases support our main claim. We conclude by briefly considering implications of this view for developing intervention and treatment strategies. (shrink)

I argue here that the ways we experience, think about, and treat pain are bound up with sociocultural and technological phenomena that shape our desires and expectations. I propose a way of imagining caring for and offering healing to those who suffer pain informed by the Christian theological tradition. This way does not aspire to replace the care and healing made possible by modern medicine, but rather to place it within the common life of a community of mutual love, hospitality, (...) and reciprocal care.

Affordances are action-possibilities, ways of relating to and acting on our world. A theory of affordances helps us understand how we have bodily access to our world and what it means to enjoy such access. But what happens to bodies when this access is somehow ruptured or impeded? This question is relevant to psychopathology. People with psychiatric disorders often describe feeling as though they’ve lost access to affordances that others take for granted. Focusing on schizophrenia, depression, and autistic spectrum disorder, (...) I argue that thinking about the bodily consequences of losing access to everyday affordances can help us better understand these reports. An affordance-based approach to psychopathology can illuminate some of the causes, as well as the experiential character and content, of affective disorders in psychopathology. It can also draw our attention to some under-explored ethical and political dimensions of these issues needing further consideration. (shrink)

I respond to the commentaries on 'Grace de Laguna's Analytic and Speculative Philosophy' offered by Peter Olen [2023], Trevor Pearce, Anthony Fisher, Marguerite La Caze and Frederique Janssen-Lauret. In doing so, I bring out some of the value of de Laguna’s perspectivism and of her treatment of modality. I also further clarify how she departs from pragmatism and from analytic philosophy, and how she relates to continental philosophy.
