This volume concerns the status and ambitions of metaphysics as a discipline.

In his postapocalyptic novel, Those Who Remain, G. Michael Hopf (2016) makes an important observation about the effect crises can have on human psychology by noting that "hard times create strong [humans]" (loc. 200). While the catastrophic effects of the recent COVID-19 outbreak are incontestable, there are arguments to be made that the situation itself could be materia prima of a more grounded, and authentic generation of humanity, at least in theory. In this article I draw on Heidegger's early, implicit (...) ethic of finitude as well as his later work surrounding the nature of technology, and place them into dialogue with a global milieu contextualized by worldwide pandemic. I approach this discussion from two different angles: in the first part, I explicate the ethic of finitude, and use it as a framework to describe the observable behavior of communities worldwide in order to better understand how global crises impact the psychical welfare of individual human beings. In the second part, I apply lessons given to us by the later Heidegger, specifically those oriented around the movement away from calculative thinking, in an effort to define a loose, albeit fundamentally ennobling prescriptive aimed at easing the existential strain of the situation we have found ourselves in. *This is a pre-print of an article published in Human Arenas.

Ryan Wasserman explores a range of fascinating puzzles raised by the possibility of time travel, with entertaining examples from physics, science fiction, and popular culture, and he draws out their implications for our understanding of time, tense, freedom, fatalism, causation, counterfactuals, laws of nature, persistence, change, and mereology.

Including significant passages from The Prince, The Discourses, The Art of War and History of Florence, this illuminating book explores the influence of Machiavelli, who was often reviled as a teacher of evil, on the modern state.

This book is the first comprehensive study of Schopenhauer's philosophy of religion. It develops a contextual account of Schopenhauer's relation to the religions of India by placing his interpretation of their main doctrines within the perspective of his diagnosis of the religious situation in nineteenth-century Europe, and his revised conception of the proper content and methods of metaphysical philosophy in the wake of Kant. It shows that Schopenhauer's encounter with the religions of India was the stimulus for his formulation of (...) a novel theory of a revitalised modern Christianity. The possibility of an oriental renaissance prompted Schopenhauer to argue that Christianity's immanent or ethical teachings needed to be severed from its supernatural or metaphysical doctrines, so that European culture could continue to satisfy the human need for a metaphysical interpretation of the world and life. This book will be of interest to philosophers, theologians, students of religion and modern intellectual history. (shrink)

This thought-provoking book discusses the concept of progress in economics and investigates whether any advance has been made in its different spheres of research. The authors look back at the history, successes and failures of their respective fields and thoroughly examine the notion of progress from an epistemological and methodological perspective. The idea of progress is particularly significant as the authors regard it as an essentially contested concept which can be defined in many ways – theoretically or empirically; locally or (...) globally; or as encouraging or impeding the existence of other research traditions. The authors discuss the idea that for progress to make any sense there must be an accumulation of knowledge built up over time rather than the replacement of ideas by each successive generation. Accordingly, they are not concerned with estimating the price of progress, reminiscing in the past, or assessing what has been lost. Instead they apply the complex mechanisms and machinery of the discipline to sub-fields such as normative economics, monetary economics, trade and location theory, Austrian economics and classical economics to critically assess whether progress has been made in these areas of research. -/- Bringing together authoritative and wide-ranging contributions by leading scholars, this book will challenge and engage those interested in philosophy, economic methodology and the history of economic thought. It will also appeal to economists in general who are interested in the advancement of their profession. (shrink)

AI and people do not compete on a level-playing field. Self-driving vehicles may be safer than human drivers, but laws often penalize such technology. People may provide superior customer service, but businesses are automating to reduce their taxes. AI may innovate more effectively, but an antiquated legal framework constrains inventive AI. In The Reasonable Robot, Ryan Abbott argues that the law should not discriminate between AI and human behavior and proposes a new legal principle that will ultimately improve human (...) well-being. This work should be read by anyone interested in the rapidly evolving relationship between AI and the law. (shrink)

When are morally good actions beautiful, when indeed they are? In this paper, it is argued that morally good actions are beautiful when they appear to express the deep or true self, and in turn tend to give rise to an emotion which is characterised by feelings of being moved, unity, inspiration, and meaningfulness, inter alia. In advancing the case for this claim, it is revealed that there are additional sources of well-formedness in play in the context of moral beauty (...) in addition to those that have tended to be focused on to date: one which is connected to imagining a deep location for the goodness concerned, and another which is connected to imagining that the goodness stems from capacities which are essential to the person.

What is the nature of the concept BEAUTY? Does it differ fundamentally from nearby concepts such as PRETTINESS? It is argued that BEAUTY, but not PRETTINESS, is a dual-character concept. Across a number of contexts, it is proposed that BEAUTY has a descriptive sense that is characterised by, inter alia, having intrinsically pleasing appearances; and a normative sense associated with deeply-held values. This account is supported across two, pre-registered, studies (N=500), and by drawing on analysis of corpus data. It is (...) suggested that this can help to explain why beauty, unlike prettiness, is thought to be deep in both the sense of being important, and in the sense of being less closely tied to sensory surfaces.

According to the most important objection to the existence of moral beauty, true judgements of moral beauty are not possible as moral judgements require being motivated to act in line with the moral judgement made, and judgements of beauty require not being motivated to act in any way. Here, I clarify the argument underlying the objection, and show that it does not show that moral beauty does not exist. I present two responses: namely, that the beauty of moral beauty does (...) not lie in the moral goodness per se (the “adjacent properties” response); and that only a dispositional motivation to act is required for the moral judgements that are typically made as part of judgements of moral beauty, whereas aesthetic judgements only rule out state motivations to act (the “equivocation of motivation required” response). In addressing the objection, I show how moral beauty is consistent with disinterestedness, and so should be accepted more widely; and also clarify where the beauty in moral beauty resides, and how the moral-aesthetic distinction should be drawn.

Repetition priming of object identification refers to the phenomenon whereby experience with an object induces systematic changes in subsequent processing of that same object. This data-driven form of priming is distinct from conceptually-driven priming. To date, considerable controversy exists about whether data-driven priming reflects facilitation in perceptual processing or mediation by preexisting object representations. The present study concerned priming of recognizing familiar and unfamiliar faces and how this priming is influenced by face inversion, which interferes with perceptual face processing. Perceptual (...) and representation-based loci conjointly contributed to priming; the perceptual locus was operative similarly for familiar and unfamiliar faces, whereas the representation-based locus was only invoked for familiar faces and resulted in a response-time reduction triple the magnitude of that from the perceptual locus. The results constrain theoretical accounts of data-driven priming by indicating that improved identification can result from the combination of perceptual and representation-based facilitation.

This paper is a fragment of the book “Kaja od Radosława, czyli historia Hubalowego Krzyża”, which was published by Warszawskie Wydawnictwo Literackie Muza in 2006. It will be published by the American publisher The Military History Press under the title “Kaia Savior of the Hubal Cross”. Covering a century of Polish history, it is full of tragic and compelling events. Such historic events as Polish life in Siberia, Warsaw before the war, the German occupation, the Warsaw Uprising, life in Ostaszków, (...) and the rebuilding of Warsaw are included.The hero Kaia is a woman, christened Cesaria, whose father was expelled to Siberia in 1905 for conspiring against the tsar. Kaia spent her early childhood there, and the family lived near the mountain Altaj. A chapter shows how the Polish community lived there, organized their daily lives, etc. In 1922, the family returned to free Poland, the train trip back taking almost a year. This ordeal is highlighted as a series of stops sometimes lasting for weeks because of heavy snow accumulation, the men shoveling a pathway for the train to pass through, many deaths occurring from the frigid cold with the “caboose” used as a mortuary for Poles to be returned to their homeland for burial. Kaia entered the school system, was eventually educated as an architect, and then World War II started. She lived under the German occupation for the first few years, and later became a conspirator by helping the underground movement. She joined the Armia Krajowa in 1942. At considerable risk, her apartment became a meeting place for the conspirators.After Hubal’s death, one of his couriers gave Kaia the Hubal Cross Virtuti Militari. The cross was with her for the ensuing 50 years. During the Warsaw Uprising, in which she was a courier, she carried the cross around her neck. Many times, she had to travel via the Warsaw underground sewer system. Twice, she was wounded. After the Warsaw Uprising collapsed, she went to the east territory to look for her mother. She was captured by the Russian NKVD in Białystok and sent to Ostaszków. An interesting scene describes one of many interrogations: the Russian interrogator asks if she knows about the cross. Her reply causes a puzzled look on his face. The cross was never discovered (she had hidden it in a specially made shoe). Protection of the Virtuti Militari Cross, which at first had been a challenge to Kaia to survive the Uprising and Russian imprisonment, later became a symbol of courage and determination of the Polish people. In 1946, Kaia returned to Poland very ill and weighing only 38 kg (83.6 pounds). Eventually recovering her health, she worked as an architect involved in the rebuilding of Warsaw totally decimated by the Germans.In the Warsaw Uprising chapter, Kaia’s diary is included, and the book relates the scenes and events that she described. One such experience is most moving. It was a quiet moment, i.e. the shooting had subsided. On a warm beautiful August night, she was sitting, enjoying the quiet alone when, a young man sat down next to her. He was a colleague from architectural school. Together, a few months earlier, they had attended a university ball, and Kaia remembered him as always being funny and amusing. Then, she noticed he was missing one eye and part of his chin. He returned her gaze and jokingly said, “I still have one eye left”. And then, he quietly sang a popular song that they had danced the waltz to… “Not to be in love on such a beautiful night is a sin”… Kaia had to be in the same mood as he was and smiled. A few days later, half of his body was covered in ruins…he could not be helped. His death lasted several days, and he is buried in Powązki Cemetery, like many soldiers of the Uprising. (shrink)

Very diverse societies pose real problems for Rawlsian models of public reason. This is for two reasons: first, public reason is unable accommodate diverse perspectives in determining a regulative ideal. Second, regulative ideals are unable to respond to social change. While models based on public reason focus on the justification of principles, this book suggests that we need to orient our normative theories more toward discovery and experimentation. The book develops a unique approach to social contract theory that focuses on (...) diverse perspectives. It offers a new moral stance that author Ryan Muldoon calls, "The View From Everywhere," which allows for substantive, fundamental moral disagreement. This stance is used to develop a bargaining model in which agents can cooperate despite seeing different perspectives. Rather than arguing for an ideal contract or particular principles of justice, Muldoon outlines a procedure for iterated revisions to the rules of a social contract. It expands Mill's conception of experiments in living to help form a foundational principle for social contract theory. By embracing this kind of experimentation, we move away from a conception of justice as an end state, and toward a conception of justice as a trajectory. (shrink)

Why are moral actions beautiful, when indeed they are? This paper assesses the view, found most notably in Schiller, that moral actions are beautiful just when they present the appearance of freedom by appearing to be the result of internal harmony (the Schillerian Internal Harmony Thesis). I argue that while this thesis can accommodate some of the beauty involved in contrasts of the ‘continent’ and the ‘fully’ virtuous, it cannot account for all of the beauty in such contrasts, and so (...) needs to be weakened considerably (to the Internal Harmony Thesis). To account for the remaining beauty that cannot be fully accommodated even by this revised thesis, as well as the beauty contained in contrasts that involve agents who experience internal conflict as a result of being sensitive to different sources of moral value to an appropriate extent, a number of further theses need to be posited: namely, that the beauty of some moral actions is to be accommodated in terms of internal disharmony (the Internal Disharmony Thesis), and in terms of a felt harmony between the appreciator of the action and the executor of the action (the Affective Harmony Thesis). As such, in contrast to Schiller, I suggest that we need to take a pluralist and context-sensitive approach to accommodating the beauty of moral actions. (shrink)

This book explores the constraints which justice imposes on immigration policy. Like liberal nationalists, Ryan Pevnick argues that citizens have special claims to the institutions of their states. However, the source of these special claims is located in the citizenry's ownership of state institutions rather than in a shared national identity. Citizens contribute to the construction and maintenance of institutions, and as a result they have special claims to these institutions and a limited right to exclude outsiders. Pevnick shows (...) that the resulting view justifies a set of policies - including support for certain types of guest worker programs - which is distinct from those supported by either liberal nationalists or advocates of open borders. His book provides a framework for considering a number of connected topics including issues related to self-determination, the scope of distributive justice and the significance of shared national identity.

Coronavirus disease 2019 can lead to respiratory failure. Some patients require extracorporeal membrane oxygenation support. During the current pandemic, health care resources in some cities have been overwhelmed, and doctors have faced complex decisions about resource allocation.

Experts in critical care, end-of-life care, bioethics, and (...) health policy discuss if age should guide rationing decisions. (shrink)

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

In this article, I examine A. John Simmons’s philosophical anarchism, and specifically, the problems that result from the combination of its three foundational principles: the strong correlativity of legitimacy rights and political obligations; the strict distinction between justified existence and legitimate authority; and the doctrine of personal consent, more precisely, its supporting assumptions about the natural freedom of individuals and the non-natural states into which individuals are born. As I argue, these assumptions, when combined with the strong correlativity and strict (...) distinction theses, undermine Simmons’s claim, which is central to his philosophical anarchism, that a state may be justified in enforcing the law, even if illegitimate or unjustified in existing.

Applies a philosophical analysis of the natural sciences to the social sciences.

In epistemology and the philosophy of science, there has been an increasing interest in the social aspects of belief acquisition. In particular, there has been a focus on the division of cognitive labor in science. This essay explores several different models of the division of cognitive labor, with particular focus on Kitcher, Strevens, Weisberg and Muldoon, and Zollman. The essay then shows how many of the benefits of the division of cognitive labor flow from leveraging agent diversity. The essay concludes (...) by examining the benefits and burdens of diversity, particularly in the evaluative diversity that can be found in interdisicplinary science. (shrink)

The Eleatic philosophers argued that it was impossible for anything to change, since that would require something to differ from itself. Although this line of reasoning is unpersuasive, it challenges us to provide an account of temporal predication, which is the focus of much recent work on change. This paper surveys various approaches to change and temporal predication and addresses related questions about identity, persistence, properties, time, tense, and temporal logic.

In recent years the doctrine of divine simplicity has become a topic of interest in the philosophical theological community. In particular, the modal collapse argument against divine simplicity has garnered various responses from proponents of divine simplicity. Some even claiming that the modal collapse argument is invalid. It is our contention that these responses have either misunderstood or misstated the argument, and have thus missed the force of the objection. Our main aim is to clarify what the modal collapse argument (...) in fact says, and explain why the recent responses do not succeed. In order to argue our case, we will proceed in several steps. First, we aim to systematically articulate the doctrine of divine simplicity. Second, articulate the Christian conviction that God is free to create any feasible world or no world at all. Third, argue that divine simplicity suffers a modal collapse and thus undermines God's freedom. Fourth, respond to potential objections to modal collapse. Fifth, we offer some concluding remarks.

In this paper we argue that there is a kind of moral disagreement that survives the Rawlsian veil of ignorance. While a veil of ignorance eliminates sources of disagreement stemming from self-interest, it does not do anything to eliminate deeper sources of disagreement. These disagreements not only persist, but transform their structure once behind the veil of ignorance. We consider formal frameworks for exploring these differences in structure between interested and disinterested disagreement, and argue that consensus models offer us a (...) solution concept for disagreements behind the veil of ignorance.

This essay explores the relation between democracy and social equality. It critically evaluates the relational egalitarian view that democracy is necessary for full social equality and that democracy is an important constituent of social equality. On such a view, inequalities in power an de facto authority are taken, in certain circumstances, to constitute a form of social inequality. On the basis of a series of cases, I argue that such a view is mistaken, and that political inequalities are, at best, (...) empirically and contingently related to social inequality. I argue that what is primarily wrong with inequalities in power and de facto authority is not that, in certain circumstances, they constitute a form of social inequality, but rather that they can be used to extract greater consideration for those with greater power.

[To readers: Please consider visiting the journal's website to read this work.] In spite of referring to the human tendency to "breath together" or share the same spirit, the word "conspire" has developed a negative connotation in contemporary society, specifically as it pertains to theorizing about conspiracies as a result of the human proclivity to recognize patterns recognition and coalesce common themes amongst those with shared perceptions into something resembling a unified narrative. This proclivity has only become more pronounced with (...) the dawn of the Internet age, and as a result, the tendency to assume the actuality of certain conspiracies and insulate ourselves from viable, competing ideas has led to a series of microenvironments not dissimilar from those that allow for the proliferation of cancerous cells in the human body. In this article, I draw out the analogy between cancer and conspiracy theorizing in order to present readers with a clearer picture of the deleterious effects of the contemporary phenomena such as unbridled political polarization and the effect of sociopolitical news coverage presented by low-correlation outlets, otherwise known as "echo chambers.".

This paper focuses on a recently articulated, emergentist conception of ethical naturalism and its commitment to causal efficacy, or the idea that moral properties have causal powers, along with its supporting commitment to moral causation. After I reconstruct the theory, I explain how it offers some interesting theoretical benefits to moral realists in virtue of its commitment to causal efficacy. Then, after locating some examples of moral causation in support of this commitment, I present and respond to five objections to (...) such causation, which all threaten to undermine this support. Lastly, I consider a very serious problem that the theory faces in virtue of positing emergent moral properties as responsible for moral causation – namely, the problem of downward moral causation. I describe this problem in detail and argue that, as it stands, it does not spell doom for the theory. (shrink)

Deep brain stimulation is an experimental procedure for treatment-resistant depression. Some results show promise, but blinded trials had limited success. Ethical questions center on vulnerability: especially on whether depressed patients can weigh the risks and benefits effectively, whether depression causes “desperation,” and whether media portrayals create unrealistic hopes. We interviewed 24 psychiatric inpatients with treatment-resistant depression, qualitatively analyzing their comments. Most had minimal interest in deep brain stimulators. Some might consider them if their depression worsened, if alternatives were exhausted, or (...) if the evidence were stronger. Fears focused on the surgery, adverse effects, and the novelty of the device. Patients felt the depression interfered with their ability to weigh the risks and benefits. Patients seemed highly attuned to the risks, and were skeptical that the treatment would be effective. We conclude that ethical concerns about vulnerability remain, yet patients with treatment-resistant depression were thoughtful and cautious about trying a novel therapy. (shrink)

DNA sequencers, Twitter, MRIs, Facebook, particle accelerators, Google Books, radio telescopes, Tumblr: what do these things have in common? According to the evangelists of “data science,” all of these are instruments for observing reality at unprecedentedly large scales and fine granularities. This perspective ignores the social reality of these very different technological systems, ignoring how they are made, how they work, and what they mean in favor of an exclusive focus on what they generate: Big Data. But no data, big (...) or small, can be interpreted without an understanding of the process that generated them. Statistical data science is applicable to systems that have been designed as scientific instruments, but is likely to lead to confusion when applied to systems that have not. In those cases, a historical inquiry is preferable. (shrink)

Does the formation of delusions involve abnormal reasoning? According to the prominent ‘two-factor’ theory of delusions (e.g. Coltheart, 2007), the answer is yes. The second factor in this theory is supposed to affect a deluded individual's ability to evaluate candidates for belief. However, most published accounts of the two-factor theory have not said much about the nature of this second factor. In an effort to remedy this shortcoming, Coltheart, Menzies and Sutton (2010) recently put forward a Bayesian account of inference (...) in delusions. I outline some criticisms of this important account, and sketch an alternative account of delusional inference that, I argue, avoids these criticisms. Specifically, I argue that the second factor in delusion formation involves a systematic deviation from Bayesian updating, a deviation that may be characterized as a bias towards ‘explanatory adequacy’. I present a numerical model of this idea and show that my alternative account is broadly consistent with prominent prediction error models of delusion formation (e.g. Corlett, Murray et al., 2007).

What role should the physician's conscience play in the practice of medicine? Much controversy has surrounded the question, yet little attention has been paid to the possibility that disputants are operating with contrasting definitions of the conscience. To illustrate this divergence, we contrast definitions stemming from Abrahamic religions and those stemming from secular moral tradition. Clear differences emerge regarding what the term conscience conveys, how the conscience should be informed, and what the consequences are for violating one's conscience. Importantly, these (...) basic disagreements underlie current controversies regarding the role of the clinician's conscience in the practice of medicine. Consequently participants in ongoing debates would do well to specify their definitions of the conscience and the reasons for and implications of those definitions. This specification would allow participants to advance a more philosophically and theologically robust conversation about the means and ends of medicine. (shrink)

Let’s say that you regard two things as on a par when you don’t prefer one to other and aren’t indifferent between them. What does rationality require of you when choosing between risky options whose outcomes you regard as on a par? According to Prospectism, you are required to choose the option with the best prospects, where an option’s prospects is a probability-distribution over its potential outcomes. In this paper, I argue that Prospectism violates a dominance principle—which I call The (...) Principle of Predominance—because it sometimes requires you to do something that’s no better than the alternatives and might be worse. I argue that this undermines the strongest argument that’s been given in favor of Prospectism. (shrink)
