The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

Jaspers’s binary distinction between understanding and explanation has given way first to a proliferation of explanatory levels and now, in John Campbell’s recent work, to a conception of explanation with no distinct levels of explanation and no inbuilt rationality requirement. I argue that there is still a role for understanding in psychiatry and that is to demystify the assumption that the states it concerns are mental. This role can be fulfilled by placing rationality at the heart of understanding without (...) a commitment to the attempt to use rationality to shed light on interpretation and mindedness as though from outside those notions. Delusions still present a significant challenge to philosophical attempts at understanding, but this merely reflects the genuine clinical difficulties such states present. (shrink)

It is widely assumed that disability is typically a bad thing for those who are disabled. Our purpose in this essay is to critique this view and defend a more nuanced picture of the relationship between disability and well-being. We first examine four interpretations of the above view and argue that it is false on each interpretation. We then ask whether disability is thereby a neutral trait. Our view is that most disabilities are neutral in one sense, though we cannot (...) make simple generalizations about disability's relationship to well-being in other important senses. After defending this view, we discuss its practical implications for selective abortion for disability, nondisabled people's interactions with disabled people, and the use of QALYs in health policy.

Imagine that you are given access to an AI chatbot that compellingly mimics the personality and speech of a deceased loved one. If you start having regular interactions with this “thanabot,” could this new relationship be a continuation of the relationship you had with your loved one? And could a relationship with a thanabot preserve or replicate the value of a close human relationship? To the first question, we argue that a relationship with a thanabot cannot be a true continuation (...) of your relationship with a deceased loved one, though it might support one’s continuing bonds with the dead. To the second question, we argue that, in and of themselves, relationships with thanabots cannot benefit us as much as rewarding and healthy intimate relationships with other humans, though we explain why it is difficult to make reliable comparative generalizations about the instrumental value of these relationships.

To 'consequentialise' is to take a putatively non-consequentialist moral theory and show that it is actually just another form of consequentialism. Some have speculated that every moral theory can be consequentialised. If this were so, then consequentialism would be empty; it would have no substantive content. As I argue here, however, this is not so. Beginning with the core consequentialist commitment to 'maximising the good', I formulate a precise definition of consequentialism and demonstrate that, given this definition, several sorts of (...) moral theory resist consequentialisation. My strategy is to decompose consequentialism into three conditions, which I call 'agent neutrality', 'no moral dilemmas', and 'dominance', and then to exhibit some moral theories which violate each of these.

On the traditional view, moral distress arises only in cases where an individual believes she knows the morally right thing to do but fails to perform that action due to various constraints. We seek to motivate a broader understanding of moral distress. We begin by presenting six types of distress that fall outside the bounds of the traditional definition and explaining why they should be recognized as forms of moral distress. We then propose and defend a new and more expansive (...) definition of moral distress and examine how it can enable the development of a taxonomy of moral distress. (shrink)

I argue that Plato believes that the soul must be both the principle of motion and the subject of cognition because it moves things specifically by means of its thoughts. I begin by arguing that the soul moves things by means of such acts as examination and deliberation, and that this view is developed in response to Anaxagoras. I then argue that every kind of soul enjoys a kind of cognition, with even plant souls having a form of Aristotelian discrimination (...) (krisis), and that there is therefore no completely unintelligent, evil soul in the cosmos that can explain disorderly motions; as a result, the soul is not the principle of all motion but only motion in the cosmos after it has been ordered by the Demiurge.

It is widely recognized that lives and activities can be meaningful or meaningless, but few have appreciated that they can also be anti-meaningful. Anti-meaning is the polar opposite of meaning. Our purpose in this essay is to examine the nature and importance of this new and unfamiliar topic. In the first part, we sketch four theories of anti-meaning that correspond to leading theories of meaning. In the second part, we argue that anti-meaning has significance not only for our attempts to (...) theorize about meaning in life, but also for our ability to lead meaningful lives in the modern world.

In this article, I argue that online echo chambers are in some cases and in some respects good. I do not attempt to refute arguments that they are harmful, but I argue that they are sometimes beneficial. In the first section, I argue that it is sometimes good to be insulated from views with which one disagrees. In the second section, I argue that the software-design principles that give rise to online echo chambers have a lot to recommend them. Further, (...) the opposing principle, serendipity, could give rise to serious harm, in light of the conclusion of the first section that sometimes we are better off being insulated from some content online. In the third section, I argue that polarization can be a useful tool for inculcating the appropriate attitudes in a person. (shrink)

The so-called Disability Paradox arises from the apparent tension between the popular view that disability leads to low well-being and the relatively high life-satisfaction reports of disabled people. Our aim in this essay is to make some progress toward dissolving this alleged paradox by exploring the relationship between disability and various “goods of life”—that is, components of a life that typically make a person’s life go better for her. We focus on four widely recognized goods of life (happiness, rewarding relationships, (...) knowledge, achievement) and four common types of disability (sensory, mobility, intellectual, and social) and systematically examine the extent to which the four disability types are in principle compatible with obtaining the four goods of life. Our findings suggest that that there is a high degree of compatibility. This undermines the widespread view that disabilities, by their very nature, substantially limit a person’s ability to access the goods of life, and it provides some guidance on how to dissolve the Disability Paradox.

I argue that, according to Plato, the body is the sole cause of psychic disorders. This view is expressed at Timaeus 86b in an ambiguous sentence that has been widely misunderstood by translators and commentators. The goal of this article is to offer a new understanding of Plato’s text and view. In the first section, I argue that although the body is the result of the gods’ best efforts, their sub-optimal materials meant that the soul is constantly vulnerable to the (...) body’s influences. In the second section, I argue that every psychic disorder is a disruption of the motions of the inner psychic circles by the body; moreover, I defend my translation of 86b. In the final section, I argue that the goal of education is to restore the circles to their original orbits, and I disarm a possible objection that bad education is also a cause of psychic disorder.

This paper considers the use that Plato makes of the Principle of Non-Contradiction (PNC) in his engagements with eristic refutations. By examining Plato’s use of the principle in his most detailed engagements with eristic—in the Sophist, the discussion of “agonistic” argumentation in the Theaetetus, and especially the Euthydemus—I aim to show that the pressure exerted on Plato by eristic refutations played a crucial role in his development of the PNC, and that the principle provided him with a much more sophisticated (...) means of demarcating philosophical argumentation from eristic than he is generally thought to have. In particular, I argue that Plato’s qualified formulation of the PNC restricts the class of genuine contradictions in such a way that reveals the contradictions that eristics produce through their refutations to be merely apparent and that Plato consistently appeals to his qualified conception of genuine contradiction in his encounters with eristics in order to demonstrate that their refutations are merely apparent. The paper concludes by suggesting that the conception of genuine contradiction afforded by the PNC did not just provide Plato with a way of demarcating genuine from eristic refutations, but also with an answer to substantive philosophical challenges that eristics raised through their refutations.

Can the theory that reality is a simulation be tested? We investigate this question based on the assumption that if the system performing the simulation is nite (i.e. has limited resources), then to achieve low computational complexity, such a system would, as in a video game, render content (reality) only at the moment that information becomes available for observation by a player and not at the moment of detection by a machine (that would be part of the simulation and whose (...) detection would also be part of the internal computation performed by the Virtual Reality server before rendering content to the player). Guided by this principle we describe conceptual wave/particle duality experiments aimed at testing the simulation theory. (shrink)

This essay introduces and defends a new analysis of prudential value. According to this analysis, what it is for something to be good for you is for that thing to contribute to the appeal or desirability of being in your position. I argue that this proposal fits well with our ways of talking about prudential value and well-being; enables promising analyses of the related concepts of luck, selfishness, self-sacrifice, and paternalism; preserves the relationship between prudential value and the attitudes of (...) concern, love, pity, and envy; and satisfies various other desiderata. I also highlight two ways in which the analysis is informative and can lead to progress in our substantive theorizing about the good life. (shrink)

It seems better to have a life that begins poorly and ends well than a life that begins well and ends poorly. One possible explanation is that the very shape of a life can be good or bad for us. If so, this raises a tough question: when can the shape of our lives be good or bad for us? In this essay, I present and critique an argument that the shape of a life is a non-synchronic prudential value—that is, (...) something that can be good or bad for us in a way that is not good or bad for us at any particular time. After distinguishing two interpretations of ‘the shape of a life’, I argue that the first type of shape can be good or bad for us at particular moments while the other cannot be good or bad for us at all. This suggests that the shape of a life gives us no reason to posit non-synchronic prudential values. (shrink)

This article concerns the place of Plato’s eschatology in his philosophy. I argue that the theory of reincarnation appeals to Plato due to its power to explain how non-human animals came to be. Further, the outlines of this theory are entailed by other commitments, such as that embodiment disrupts psychic functioning, that virtue is always rewarded and vice punished, and that the soul is immortal. I conclude by arguing that Plato develops a view of reincarnation as the chief tool that (...) the gods have to ensure that virtue is victorious over vice throughout the whole cosmos. (shrink)

This paper formalizes the role of possibility as the first moral good within the ethical framework of Infrastructuralism. I argue that survival does not hold moral primacy on its own; rather, its significance derives from its function in preserving possibility. Possibility is the precondition for evaluative space, agency, and moral judgment. Without the possibility of choice, no moral value, preference, or normative assessment can exist. Thus, possibility is not morally neutral but constitutes the foundational good from which all other moral (...) goods emerge. I introduce and formalize the Possibility Clause, demonstrate how possibility generates the first moral good through the creation of evaluative space, and establish the first moral imperative: to preserve possibility. Several logical guard mechanisms are presented to show that denials of possibility’s moral status collapse into self-contradiction. This work clarifies the substrate of moral value in Infrastructuralism and sets the foundation for applications in human ethics, institutional design, and AI alignment. (shrink)

In 1947 Donald Cary Williams claimed in The Ground of Induction to have solved the Humean problem of induction, by means of an adaptation of reasoning first advanced by Bernoulli in 1713. Later on David Stove defended and improved upon Williams’ argument in The Rational- ity of Induction (1986). We call this proposed solution of induction the ‘Williams-Stove sampling thesis’. There has been no lack of objections raised to the sampling thesis, and it has not been widely accepted. In our (...) opinion, though, none of these objections has the slightest force, and, moreover, the sampling thesis is undoubtedly true. What we will argue in this paper is that one particular objection that has been raised on numerous occasions is misguided. This concerns the randomness of the sample on which the inductive extrapolation is based. (shrink)

According to the orthodox interpretation of Zeno's plurality paradoxes defended by Platonists, these arguments indirectly defend Parmenidean monism by showing that things are not many. But Simplicius, and the various other orthodox interpreters whom he discusses, were aware of and attempted to undermine a competing ‘heterodox’ interpretations, which were prominent in the peripatetic tradition, according to which some of Zeno’s arguments pose a threat to, or even specifically target, Parmenides. I argue that our surviving peripatetic reports according to which Zeno (...) challenged the idea that any being qualifies as a 'one' are credible and that attempts by ancient orthodox interpreters to accommodate these heterodox reports are not successful.

With an eye on the future of global ethics, I argue that social-media technologies are not morally neutral tools but are, for all intents and purposes, a kind of agent. They nudge us to do things that are bad for us. Moreover, I argue that we have a duty to quit using social-media platforms, not just on account of possible duties to preserve our own well-being but because users are akin to test subjects on whom developers are testing new nudges, (...) and we ought to deprive them of their test subjects.

This paper concerns Plato’s characterization of the body as the soul’s tool. I take perception as an example of the body’s usefulness. I explore the Timaeus’ view that perception provides us with models of orderliness. Then, I argue that perception of confusing sensible objects is necessary for our cognitive development too. Lastly, I consider the instrumentality relationship more generally and its place in Plato’s teleological worldview.

This document introduces the Core Moral Equation (CME), a mathematical model derived from Infrastructuralism, a normative ethical theory that evaluates moral actions based on their impact on shared, viability-enabling infrastructure. The CME formalizes the relationship between agents, infrastructure, and moral advantage, framing failure to reinvest in shared systems as a measurable risk to moral agency itself. It introduces the Viability Margin (VM) and Viability Threshold (Vt) to define the conditions under which agents collapse and moral judgment ceases. The Herd Depletion (...) Effect (HDE) is also defined as a mechanism of collective erosion. Though presented as a standalone contribution, the CME serves as the quantitative backbone of the broader Herd Ethics framework—an ethical framework that extends to AI systems, corporations, institutions, and collective agents—any entity whose existence and agency depend on shared infrastructure. This paper lays the groundwork for future extensions where external values can be integrated into the model, enabling real-world moral risk assessment and policy design. (shrink)

Some Aristotle-inspired theorists contend that agents possess and exercise two-way causal powers: a single power that has two distinct and opposed manifestations, at least one of which is an action. In this paper, I argue that Aristotle recognizes no such power. The possessor of a rational power—which I argue is the most plausible candidate for such a two-way power in Aristotle (§2)—can bring about two distinct and contrary changes. But the immediate activity of a rational power itself is simply a (...) matter of contemplating the account of one or the other of two contrary objects of knowledge (§§3-4). This ‘two-way’ character of knowledge does not reflect a special feature of human knowers: a rational power that consists in knowing the account of one contrary (F+) enables one to know the account of the other (F–) simply because what it is to be F+ is part of what it is to be F– (§5). Rational powers are thus not single origins of the opposed changes that their possessors produce. Instead, the account of F+ is one power in a causal chain involving a plurality of powers that ultimately leads to the production of F+ or F– (§6). (shrink)

This article is featured in a special issue dedicated to theme, "the human being in the digital era: awareness, critical thinking and political space in the age of the internet and artificial intelligence." In this article, I consider the way that social-media companies nudge us to spend more time on their platforms, and I argue that, in principle, these nudges are morally permissible: they are not manipulative and do not violate any obvious moral rules. The moral problem, I argue, is (...) not with nudging in principle but is instead with the fact that users are being nudged towards something bad for them. In practice, this often involves being nudged to spend an unhealthy amount of time using a social-media app or being nudged towards content that is bad for us, such as by promoting eating-disorder content to young girls. Since nudging is morally permissible, it is open to these companies to use the same technologies to nudge us towards the good. (shrink)

This chapter provides an account of the relation between Deleuze’s philosophy and music. It begins with an outline of Deleuze’s engagement with music, individually and in collaboration with Guattari, accounting both for direct engagement with composers, performers, and works, and for philosophical notions with musical provenance. Topics covered here include temporal and perceptual themes in Deleuze’s and Deleuze and Guattari’s explicit writing on music, their engagement with composers including Pierre Boulez, Olivier Messiaen, and John Cage, their account of modernism, and (...) their notion of the refrain as it appears in A Thousand Plateaus in particular. It then turns to the engagement with and uptake of Deleuze’s thought in music and music scholarship. Topics here include the influence of Deleuze on composers and other musicians inside and outside of ‘art music’, adaptations of Deleuze’s thought in the theorisation of music beyond Deleuze’s own primary concerns, such as jazz and other Afrodiasporic musics, and the use of Deleuzian ideas such as the assemblage in musicology and sound studies. It closes with some reflections on the significance of the apparent unfaithfulness of some adaptations of Deleuze’s thought and on how we might understand Deleuze’s modernism today. (shrink)

Interpreters of Plato’s Euthydemus have often detected apparent Eleatic allegiances in the dialogue’s eponymous character and his brother Dionysodorus. However, according to another prominent line of interpretation, we should not attribute any doctrinal commitments to the eristic brothers in the Euthydemus. Indeed, the latter view seems to gain support from Socrates’ claim that the brothers’ ‘eristic wisdom’ enables them to refute whatever their interlocutor says, regardless of whether it is true or false (Euthyd. 272a7-b1). In this paper, I show that (...) Plato does in fact attribute certain doctrinal commitments to Euthydemus and argue that these commitments are closely related to his larger argumentative practice. On the view I propose, Euthydemus’ aim in refuting his opponents is not simply to propound contradictions and paradoxes. He instead reduces his interlocutors to self-contradiction with the ultimate aim of defending a philosophical doctrine that provides one with a way out of these paradoxes. More precisely, I take the philosophical doctrine that Euthydemus defends to be a radical form of monism, often associated with the Eleatics and I suggest that the argumentative practice by which he defends this doctrine to also has Eleatic pedigree. On the reading I propose, Euthydemus’ ultimate aim in propounding his refutations is to reveal that his interlocutor’s apparently commonsense opinions are likewise paradoxical, and thus do not enjoy a greater plausibility than the radical monism that he espouses.

Disability and enhancement are often treated as opposing concepts. To become disabled in some respect is to move away from those who are enhanced in that same respect; to become enhanced is to move away from the corresponding state of disability. This chapter examines how best to understand the concepts of disability and enhancement in this symmetrical way. After considering various candidates, two types of accounts are identified as the most promising: welfarist accounts and typical-functioning accounts. The authors ultimately defend (...) a complex typical-functioning account as the best way to achieve a symmetrical understanding of disability and enhancement. (shrink)

In this essay we will take the American experimental composer John Cage’s understanding of sound as the starting point for an evaluation of that term in the field of sound studies. Drawing together two of the most influential figures in the field, Cage’s thought and work will serve as a lens through which to engage with recent debate concerning the uptake in sound studies of the philosophy of Gilles Deleuze. In so doing we will attempt to develop a path between (...) conflicting sides of sound studies, putting forward an understanding of sound that presents it not as an uninterrogated ontological essence, nor as only a term in a discursive web, but as a problem which must be repeatedly posed anew. We will consider points where this may yet be pushed towards a reified, essentialized understanding of the nature of sound, but move to offset this by emphasizing the production of a practical process of learning and experimentation.

In Metaphysics Γ.3, Aristotle argues that it is impossible to deny the PNC. However, as several commentators—including Code, Barnes, Priest, Kirwan, and Dancy—have objected, Aristotle’s argument appears to rely on the invalid inference from 1 to 2 as follows: 1. For all p, it is impossible to believe that p and not-p. 2. Therefore, it is impossible to believe that it is possible that there is a p such that p and not-p. We argue that this objection turns on a (...) misunderstanding of Aristotle’s text, and that Aristotle's argument is valid and quite strong. (shrink)

I argue that Plato thinks that the soul has location, surface, depth, and extension, and that the Timaeus’ composition of the soul out of eight circles is intended literally. A novel contribution is the development of an account of corporeality that denies the entailment that the soul is corporeal. I conclude by examining Aristotle’s objection to the Timaeus’ psychology and then the intellectual history of this reading of Plato.

This article evaluates the theoretical and practical grounds of recent debates around Christoph Cox’s realist project of a ‘sonic materialism’ by returning to Gilles Deleuze, a key theoretical resource for Cox. It argues that a close engagement with Deleuze’s work in fact challenges many of the precepts of Cox’s sonic materialism, and suggests a rethinking of materialism in the context of music. Turning to some aspects of Deleuze’s work neglected by Cox, the ‘realist’ ontological inquiry Cox affirms is challenged through (...) the ‘onto-ethology’ that Deleuze and Félix Guattari develop in their A Thousand Plateaus, with this diversely constructive theory of relations explicated through musical examples from John Cage and Pauline Oliveros. To conclude, this article suggests that Deleuze can indeed be understood as subscribing to a materialism, but a materialism that is practical rather than doctrinal. (shrink)

This paper examines the way in which Plato, in the Euthydemus, exposes sophistical refutations that exploit various forms of linguistic ambiguity. In arguing that Plato is capable of doing this, the argument of this paper challenges a common view according to which Plato lacks the technical resources necessary to diagnose fallacious arguments that turn on ambiguity. I argue instead that Plato has a much more robust sensitivity to ambiguity and its pernicious effects on philosophical arguments than has been recognized, that (...) he has at his disposal various strategies for exposing the eristic refutations that exploit linguistic ambiguity as merely apparent refutations, and that Plato's treatment of these arguments laid important groundwork for Aristotle’s understanding of genuine refutation in the Sophistici Elenchi.

In this article, I approach some phenomena seen predominantly on social-media sites that are grouped together as cancel culture with guidance from two major themes in Plato’s thought. In the first section, I argue that shame can play a constructive and valuable role in a person’s improvement, just as we see Socrates throughout Plato’s dialogues use shame to help his interlocutors improve. This insight can help us understand the value of shaming people online for, among other things, their morally reprehensible (...) views. In the second section, I argue that it is required for the proper functioning of democratic institutions that some views be excluded from the public sphere, which follows some Platonic ideas from the Laws. In neither case do I argue that this approach is good in an unqualified sense or even ultima facie good. However, I maintain that these important insights from Plato’s dialogues illuminate crucial aspects of how we should think about cancel culture. (shrink)

This document introduces Infrastructuralism, a normative ethical theory that evaluates moral actions based on their impact on shared, viability-enabling infrastructure. Unlike utilitarianism, deontology, or virtue ethics, Infrastructuralism is grounded in the structural preconditions that make moral agency possible. -/- It presents four original structural guards, including Campbell’s Paradox, the Possibility Clause, the Moral Preservation Principle, and the Impossibility of Amoralism Principle, which together defend the necessity of preserving the viability-enabling infrastructure that makes moral judgment possible. -/- While rooted in (...) moral philosophy, Infrastructuralism is not limited to human-centric ethics. It extends to AI systems, corporations, institutions, and collective agents, any entity whose existence and agency depend on shared infrastructure. It also serves as the foundational normative theory underlying the Herd Ethics framework, a derived application focused on inter-agent moral responsibility and infrastructure-sustaining policy. -/- .

In this paper I offer a model-theoretic interpretation of Autonomy Theory as defended by Moreno, Mossio, Montévil, and Bich. I address accusations that Autonomy Theory is excessively liberal, such as those made by Garson (2017), arguing that these misunderstand the role of strategic abstractions and generalizations in theory construction. Conceiving of closure of constraints as a model-building effort that emphasizes generality—in the spirit of Levins (1966)—also clarifies its potential for application in empirical contexts.

This thesis focuses on expressively rich languages that can formalise talk about probability. These languages have sentences that say something about probabilities of probabilities, but also sentences that say something about the probability of themselves. For example: (π): “The probability of the sentence labelled π is not greater than 1/2.” Such sentences lead to philosophical and technical challenges; but can be useful. For example they bear a close connection to situations where ones confidence in something can affect whether it is (...) the case or not. The motivating interpretation of probability as an agent's degrees of belief will be focused on throughout the thesis. This thesis aims to answer two questions relevant to such frameworks, which correspond to the two parts of the thesis: “How can one develop a formal semantics for this framework?” and “What rational constraints are there on an agent once such expressive frameworks are considered?”.

Abstract:In this paper, I evaluate the possibility of convergence between animal welfare and environmental ethics. By surveying the most prominent views within each of these respective camps, I argue that animal welfare ethics and ecological theories in environmental ethics are incommensurable in virtue of their respective individualistic and holistic value theories. I conclude by arguing that this conceptual clarification allows us to see that animal welfare ethics can nevertheless be made commensurable with theories in environmental ethics according to which value (...) primarily resides in individuals, rather than in collectives and communities.

I propose in this text a rhythmic theory of signs drawn from the thought of Gilles Deleuze and Félix Guattari. I name this theory a semiorhythmology. I suggest that the theory of rhythm developed in A Thousand Plateaus (1980) can be understood, in part, as the culmination of the diverse set of inquiries into signs that both Deleuze and Guattari undertook, individually and together, beginning in the 1960s. I first outline Deleuze’s theory of signs as a theory of encounter as (...) developed in Proust and Signs (1964) and Difference and Repetition (1968), following which I sketch Guattari’s engagements with signs and semiotics throughout the 1960s and 1970s, particularly through his notion of “a-signifying semiotics” and the concept of the “diagram” he adapts from the semiotics of Charles Sanders Peirce. I close by showing how these heterogeneous theories of the sign are drawn together in A Thousand Plateaus through the Spinozist reading of the ethology of Jakob von Uexküll and the theorisation of rhythm in the form of the refrain.

Scholars often suppose that those who employ sophistical refutations seek argumentative victory alone. By surveying Aristotle’s testimonies about this argumentative practice, I argue that, in Aristotle’s strict sense of the term, sophistry involves using refutations in order to support certain controversial doctrines, thereby gaining a reputation for wisdom. In particular, sophists support these doctrines by presenting them as the solutions to the contradictions and paradoxes in which they ensnare their interlocutors.

It is commonly thought that disability is a harm or “bad difference” because having a disability restricts valuable options in life. In his recent essay “Disability, Options and Well-Being,” Thomas Crawley offers a novel defense of this style of reasoning and argues that we and like-minded critics of this brand of argument are guilty of an inconsistency. Our aim in this article is to explain why our view avoids inconsistency, to challenge Crawley's positive defense of the Options Argument, and to (...) suggest that this general line of reasoning employs a double standard.

According to the Standard Definition ‘a fallacious argument, as almost every account from Aristotle onwards tells you, is one that seems to be valid but is not so’ ( Hamblin 1970 : 12). Scholars take this definition to be problematic in part because ‘appearances can vary from person to person, thus making the same argument a fallacy for the one who is taken in by the appearance, and not a fallacy for the one who sees past the appearances’ ( Hansen (...) 2020 : §4.2). We argue that Aristotle's treatment of fallacy is not subjective in the way that critics of the Standard Definition allege. (shrink)

I argue that Plato thinks that a sunaition is a mere tool used by a soul (or by the cosmic nous) to promote an intended outcome. In the first section, I develop the connection between sunaitia and Plato’s teleology. In the second section, I argue that sunaitia belong to Plato’s theory of the soul as a self-mover: specifically, they are those things that are set in motion by the soul in the service of some goal. I also argue against several (...) popular and long-standing interpretations, namely, that sunaitia correspond to Aristotle’s idea of hypothetical necessity, that sunaitia are the ‘how’ in an explanation (whereas the true cause is the ‘why’), and that Plato’s causal views should be read through Aristotle’s fourfold schema. I conclude the article by surveying the history of sunaitia after Plato’s usage. (shrink)

Fourteen philosophers share their experience teaching Peirce to undergraduates in a variety of settings and a variety of courses. The latter include introductory philosophy courses as well as upper-level courses in American philosophy, philosophy of religion, logic, philosophy of science, medieval philosophy, semiotics, metaphysics, etc., and even an upper-level course devoted entirely to Peirce.

This article reconstructs Gilles Deleuze’s engagement with phenomenology, and with the phenomenological problematic of sensation, in his Francis Bacon: The Logic of Sensation. Considering Deleuze’s adoption, from the phenomenology of art, of notions of sensation and rhythm, it examines how Deleuze complexifies these phenomenological notions by aligning them with his profoundly non-phenomenological notion of the body without organs, as well as with the concepts of modulation and the diagram. In mapping Deleuze’s complexification of rhythm and his development of a logic (...) of rhythmic modulation, this article shows how Deleuze immanently refines an approach to working beyond phenomenology, through phenomenology.

Famous examples of conceivability arguments include (i) Descartes’ argument for mind-body dualism, (ii) Kripke's ‘modal argument’ against psychophysical identity theory, (iii) Chalmers’ ‘zombie argument’ against materialism, and (iv) modal versions of the ontological argument for theism. In this paper, we show that for any such conceivability argument, C, there is a corresponding ‘mirror argument’, M. M is deductively valid and has a conclusion that contradicts C's conclusion. Hence, a proponent of C—henceforth, a ‘conceivabilist’—can be warranted in holding that C's premises (...) are conjointly true only if she can find fault with one of M's premises. But M's premises are modelled on a pair of C's premises. The same reasoning that supports the latter supports the former. For this reason, a conceivabilist can repudiate M's premises only on pain of severely undermining C's premises. We conclude on this basis that all conceivability arguments, including each of (i)–(iv), are fallacious. (shrink)

In this chapter, I consider the prospects for deploying the concept of public reason in settling practical bioethical questions, focusing in particular on entitlements to healthcare. I begin by tracing the origins of the concept of public reason to the aspirations of the liberal political theorist to find a justification for the authority of government, which reconciles a basic belief in the autonomy of the individual with the legitimacy of the coercive institutions that create and govern the public sphere. I (...) then consider how the concept of public reason may be used in order to justify a universal entitlement to healthcare, paying particular attention to the work of Norman Daniels. Finally, I briefly consider the objection that an entitlement to healthcare grounded on such terms is insufficiently robust, because it downplays the values that healthcare encodes. I conclude by reflecting on whether the concept of public reason can be stretched to include a more robust conception of the value of health. (shrink)

This paper reconstructs economics as a fundamentally moral discipline by identifying its true object of concern: the preservation and expansion of moral possibility. It argues that moral evaluation requires possibility, possibility requires viable agents, and viable agents require the preservation of viability-enabling infrastructure, including biological, ecological, social, epistemic, institutional, and technological systems that sustain agency over time. Because all economic activity acts upon this infrastructure, economics is not value-neutral but constitutes the governance of moral possibility itself. -/- Building on the (...) normative ethical framework of Infrastructuralism, the paper introduces Infrastructural Economics as a structural re-foundation of economic theory. Central to this framework is the Viability Margin (VM), defined as the protective distance between an agent’s currently held viability-critical capacities, as enabled by access to viability-enabling infrastructure, and the threshold at which agency collapses (VM = Va − Vt). Economic value is redefined as the net change in Viability Margin (ΔVM), rather than as price, output, or preference satisfaction. Positive changes in VM expand moral and economic possibility, while negative changes erode it. -/- The paper formalizes three structural laws of Infrastructural Economics, redefines core economic concepts such as value, work, extraction, wealth, money, and inflation, and establishes a universal evaluative standard, the Possibility Preservation Criterion (PPC). The PPC states that an economy functions properly if and only if it preserves or increases total Viability Margin. A measurement framework is proposed that integrates existing multi-domain indicators through the Veil of Observation, demonstrating that Viability Margin is empirically tractable. -/- The framework applies across market, planned, mixed, and AI-driven economies, and explains how systems can appear successful by conventional metrics while structurally undermining the conditions required for agency. By resolving the paradox in which economic systems justify extraction using the very agency and evaluative capacity they erode, Infrastructural Economics provides a coherent moral foundation for evaluating economic legitimacy, sustainability, and governance in both present and future economies.

Katz denies that organisms created in a lab as part of a de-extinction attempt will be authentic members of the extinct species, on the basis that they will lack the original species’ defining biological and evolutionary history. Against Katz, I note that an evolutionary lineage is conferred on an organism through its inheriting genes from forebears already possessed of such a lineage, and that de-extinction amounts to a delayed, human-assisted reproductive process, in which genes are inherited from forebears long dead. (...) My conclusion is that de-extinct organisms can perfectly well have an ancient evolutionary history, contrary to what Katz claims. (shrink)
