We see no grounds for insisting that, because the concept natural number is abstract, its foundations must be innate. It is possible to specify domain general learning processes that feed into more abstract concepts of numerical infinity. By neglecting the messiness of children's slow acquisition of arithmetical concepts, Rips et al. present an idealized, unnecessarily insular, view of number development.

This article examines methodological and ethical issues of ethnographic research through the lens of Emmanuel Levinas's philosophy. Levinas is relevant to a critical analysis of ethnographic methods because his philosophy turns on the problematic relationship between self and other, among other important problems that define and guide contemporary anthropological research, including questions of responsibility, justice, and solidarity. This article utilizes Levinas's philosophy to outline a phenomenology of the “doing” of fieldwork, emphasizing the contingency of face-to-face encounters over controlled research design. (...) This account provides a basis for going beyond the polarized opposition between objective and subjective ethnographic approaches. Levinas allows for an ethically informed ethnography premised upon an acknowledgement of risk and uncertainity over researcher control or reflexivity. Providing a handful of concrete examples, the article argues that critical self-reflection about the fundamental face-to-face dimension of fieldwork is central to ethnography's ethical possibilities.

Abstract:This visual essay invites renewed reflection on the iconography of the people. In the spring of 2020, Guatemala's President Alejandro Giammattei prohibited citizens from leaving their homes to help contain the spread of the novel coronavirus known as Covid-19. Doing little to manage the spread of the virus, these curfew events gave new aesthetic and political meaning to a familiar visual genre: photographs of empty streets. For more than a century, and especially in the summer of 2020, images of crowds (...) and mass protests have provided both governments on the one hand, and protesting multitudes on the other with an aesthetic representation of the people. But this interest in collective assemblies has tended to engage only one side of the equation. To fully appreciate the visual power of the people, it is also necessary to understand those images from which people are strikingly absent. (shrink)

“Digital footprints” is an attractive, useful, and increasingly popular metaphor for thinking about Big Data. In this essay, I elaborate on this metaphor to highlight three relatively basic fallacies in the way we tend to think about Big Data: first, that they contain information on complete populations, or “N = all”; second, that they contain recordings of naturalistic behavior; and third, that they can be understood devoid of context.

Most donated organs in the United States come from brain dead donors, while a small percentage come from patients who die in “controlled,” or expected, circumstances, typically after the family or surrogate makes a decision to withdraw life support. The number of organs available for transplant could be substantially if donations were permitted in “uncontrolled” circumstances–that is, from people who die unexpectedly, often outside the hospital. According to projections from the Institute of Medicine, establishing programs permitting “uncontrolled donation after circulatory (...) determination of death,” or uDCDD, throughout the United States has the potential to provide 22,000 more donation opportunities annually. In contrast, U.S. controlled donation after circulatory determination of death, or cDCDD, cases have increased progressively over the past decade from 87 to 848 donors, but currently account for only 10.6 percent of all deceased donors. Following the IOM recommendations, several projects exploring the feasibility of uDCDD were funded by the federal government, including a grant from the Health Resources and Services Administration that supported a pilot project in New York City in which the authors of this article participated.A key feature of our protocol, and indeed of many uDCDD protocols, is the initiation of preservation methods such as chest compressions and extracorporeal membrane oxygenation shortly after death in order to perfuse and preserve the donor's organs. Critics of uDCDD argue that the means of determining death deviates from generally ascribed principles. They assert that reinstituting circulation in order to preserve organs has the effect of “undoing” the prior determination of death. The result is that cDCDD is widely accepted and practiced routinely even though it only marginally increases the number of organs available for transplantation, and uDCDD is widely considered unacceptable despite being ethically embraced and proven to significantly increase organ donation opportunities in other countries. This article explores the evolution of this counterintuitive state of affairs and calls for a policy that, in line with the IOM report, allows for both cDCDD and uDCDD protocols. (shrink)

Red Rising and Philosophy has gathered together a crew of the wisest Helldivers philosophy can offer. Could humanity's love of physical enhancements cause its extinction? Do people doom humanity by trying to all be the same? Can a person love someone, while at the same time wanting that person destroyed? Is equality always the best principle on which to organize society? What is evil, and how does it exist in contemporary life? Does one remain the same person, even after changing (...) every physical aspect of one's body?Is it moral to sell oneself into slavery, whether it's through sex or manual labor? Is it ethical to sell one's children into slavery, on the promise that their children will live in peace and tranquility? These questions and more are what make Brown'sRed Rising trilogy such an impactful story. Brown pulls no punches, and philosophy works best in such an environment.Red Rising and Philosophy is not for the timid or the faint at heart. It's notThe Passage, since no one will die from reading it, but reading it could be a life-changing experience. (shrink)

Studies of education and careers in science, technology, engineering, and math commonly use a pipeline metaphor to conceptualize forward movement and persistence. However, the “STEM pipeline” carries implicit assumptions regarding length, contents, and perceived purpose. Using the National Survey of College Graduates, we empirically measure each of these dimensions. First, we show that a majority of STEM workers report skills training throughout their careers, suggesting no clear demarcation between education and work. Second, we show that using on-the-job expertise requirements paints (...) a very different portrait of the STEM workforce—and persistence in it. Third, we show that STEM-educated workers are well-prepared for but dissatisfied with non-STEM jobs, complicating our understanding of leaving. Collectively, these results recommend expanded conceptions of STEM education and careers and contribute to studies of science and engineering workforce transitions and diversity. (shrink)

We agree with Ramsey et al. regarding the need for new methods and concepts in the study of innovation, and welcome their initiative, but are concerned that their operationalization is over-reliant on subjective judgements.

This handbook offers a deep analysis of the main forms of legal reasoning and argumentation from both a logical-philosophical and legal perspective. These forms are covered in an exhaustive and critical fashion, and the handbook accordingly divides in three parts: the first one introduces and discusses the basic concepts of practical reasoning. The second one discusses the main general forms of reasoning and argumentation relevant for legal discourse. The third one looks at their application in law as well as at (...) the different areas of legal reasoning. The handbook’s division in three parts reflects its conceptual architecture, since legal reasoning and argumentation are considered in relation to the more general types of reasoning. (shrink)

We provide a retrospective of 25 years of the International Conference on AI and Law, which was first held in 1987. Fifty papers have been selected from the thirteen conferences and each of them is described in a short subsection individually written by one of the 24 authors. These subsections attempt to place the paper discussed in the context of the development of AI and Law, while often offering some personal reactions and reflections. As a whole, the subsections build into (...) a history of the last quarter century of the field, and provide some insights into where it has come from, where it is now, and where it might go.

The Abolition of Man, C. S. Lewis's masterpiece in ethics and the philosophy of science,warns of the danger of combining modern moral skepticism with the technological pursuit of human desires. The end result is the final destruction of human nature. From Brave New World to Star Trek, from Steampunk to starships, science fiction film has considered from nearly every conceivable angle the same nexus of morality, technology, and humanity of which C. S. Lewis wrote. As a result,science fiction (...) film has unintentionally given us stunning depictions of Lewis's terrifying vision of the future. In Science Fiction and the Abolition of Man: Finding C. S. Lewis in Sci-Fi Film and Television, scholars of religion, philosophy, literature, and film explore the connections between sci-fi film and the three parts of Lewis's book:how sci-fi portrays "Men Without Chests" incapable of responding properly to moral good, how it teaches the Tao or "The Way," and how it portrays "The Abolition of Man.".

C. S. Lewis called for spiritual formation long before the term became popular: “Every Christian is to become a little Christ. The whole purpose of becoming a Christian is simply nothing else”. Lewis's call to become little Christs recalls Paul's exhortation to “put off” the old self and “put on” Christ. This paper explores what this change of costume involves from the perspective of what a “theodramatic” approach to theology that I have developed in The Drama of Doctrine (...) and Faith Speaking Understanding. I there argue that the role of doctrine is to indicate what is in Christ and direct those in Christ to participate in Christ by playing their parts in the drama of redemption. This theatrical model raises an important issue concerning the disciple's self-understanding: Is it healthy for Christians to think in terms of “acting out” what is “in Christ” or does this encourage a false sense of self – a “put on”? I respond to this question in four steps where I present a theodramatic anthropology, describe discipleship as the project of growing into/putting on Christ, consider three objections to my previous work about the relationship between persons/roles and role-playing, and respond to the objections by offering a dogmatic description of putting on Christ in soteriological, pneumatological, and eschatological terms.

Magical ersatzism is the view that possible worlds are primitive abstract entities. In On the Plurality of Worlds, David Lewis presented what appeared to many to be a devastating argument against magical ersatzism. In this paper, I show that Lewis’ central argument does not succeed. Magical ersatzism remains a viable theory of possible worlds.

Transfer of information between senders and receivers, of one kind or another, is essential to all life. David Lewis introduced a game theoretic model of the simplest case, where one sender and one receiver have pure common interest. How hard or easy is it for evolution to achieve information transfer in Lewis signaling?. The answers involve surprising subtleties. We discuss some if these in terms of evolutionary dynamics in both finite and infinite populations, with and without mutation.

Lewis signaling games illustrate how language might evolve from random behavior. The probability of evolving an optimal signaling language is, in part, a function of what learning strategy the agents use. Here we investigate three learning strategies, each of which allows agents to forget old experience. In each case, we find that forgetting increases the probability of evolving an optimal language. It does this by making it less likely that past partial success will continue to reinforce suboptimal practice. The (...) learning strategies considered here show how forgetting past experience can promote learning in the context of games with suboptimal equilibria. (shrink)

In seeking to explain the evolution of social cooperation, many scholars are using increasingly complex game-theoretic models. These complexities often model readily observable features of human and animal populations. In the case of previous games analyzed in the literature, these modifications have had radical effects on the stability and efficiency properties of the models. We will analyze the effect of adding spatial structure to two communication games: the Lewis Sender-Receiver game and a modified Stag Hunt game. For the Stag (...) Hunt, we find that the results depart strikingly from previous models. In all cases, the departures increase the explanatory value of the models for social phenomena. (shrink)

Part of the traditional Christian doctrine of sin is the claim that, due to the effects of original sin, acts of sin are inevitable. Of course, our reflection on sinful actions is shaped by how we think about human freedom and divine providence more broadly. Some have argued that libertarians have a difficult time accounting for the inevitability of sin. This paper uses David Lewis’s work on counterfactuals and possible worlds to give an account of how the inevitability of (...) sin can be understood. It then shows how both theological determinism and Molinism can give an account of sin’s inevitability so understood. In doing so, I show that sin’s inevitability only follows if we restrict our focus to certain possible worlds that share certain features with the actual world. But once such a restriction is made explicit, I then develop a framework for how the libertarian non-Molinist can also use a similar restriction to give an account of the inevitability of sin given original sin.

Dwayne Tunstall turns to Lewis Gordon's Africana existential phenomenology in an effort to untangle Marcel's “reflective method” from its involvements with colonial racism. Tunstall's book interprets Marcel's religious existentialism as a development of his attempt to resist modernity's burgeoning dehumanization but observes that Marcel's sociopolitical thought leaves antiblack racism unexamined, which amounts to a failure to attend to “the most noxious form of depersonalization existing in the twentieth century.” In this review I call into question both Marcel's conception of (...) “philosophy proper” as well as Tunstall's appropriation of that conception in order to do philosophy personally. I am also hard pressed to accept Tunstall's implication that better responses to various manifestations of dehumanization are located in “extraphilosophical” practices or his more explicit claim that “theism” succeeds where philosophy proper has failed.

In this paper, we develop the notion of a natural convention, and illustrate its usefulness in a detailed examination of indirect requests in English. Our treatment of convention is grounded in Lewis’s seminal account; we do not here redefine convention, but rather explore the space of possibilities within Lewis’s definition, highlighting certain types of variation that Lewis de-emphasized. Applied to the case of indirect requests, which we view through a Searlean lens, the notion of natural convention allows (...) us to give a nuanced answer to the question: Are indirect requests conventional? In conclusion, we reflect on the consequences of our view for the understanding of the semantics/pragmatics divide. (shrink)

Structural properties are properties something has in virtue of its mereological structure in that they are properties whose instantiation by a particular involves the parts of the particular being propertied and related in the appropriate way. Most of the literature on structural properties has focused on problems that arise from the pairing of two assumptions: (1) structural properties are universals and (2) structural properties are, in some sense, composed of the properties they involve. Chief among these difficulties is David (...) class='Hi'>Lewis’ claim that the conjunction of (1) and (2) require non-unique composition and hence entail the denial of the extensionality of parthood: butane, as well as methane, is composed of the universals carbon, hydrogen and bonded, yet they are distinct properties. This is the extensionality problem. In this paper I discuss a different problem for the conjunction of (1) and (2) and propose a single solution to both problems. First, in section two, I introduce the idea of multiple decomposition and suggest that at least some structural properties are multiply decomposable. In section three, I introduce the “problem of multiple decompositions.” This problem arises when it seems possible for a structural property to be composed of some xs and some ys even when the xs ≠ ys. Finally, in section four I show how both problems admit of a single solution by focusing on the parthood relation that holds between structural properties and their constituents. While the solution I propose is theoretically costly, I argue that this cost should be paid to retain both (1) and (2). (shrink)

Game theory has a prominent role in evolutionary biology, in particular in the ecological study of various phenomena ranging from conflict behaviour to altruism to signalling and beyond. The two central methodological tools in biological game theory are the concepts of Nash equilibrium and evolutionarily stable strategy. While both were inspired by a dynamic conception of evolution, these concepts are essentially static—they only show that a population is uninvadable, but not that a population is likely to evolve. In this article, (...) we argue that a static methodology can lead to misleading views about dynamic evolutionary processes. We advocate, instead, a more pluralistic methodology, which includes both static and dynamic game theoretic tools. Such an approach provides a more complete picture of the evolution of strategic behaviour. 1 Introduction2 The Equilibrium Methodology3 Common Interest Signalling3.1 Lewis’s signalling game3.2 Static analysis3.3 Dynamic analysis4 The Sir Philip Sidney Game4.1 Static analysis4.2 Other equilibria4.3 Dynamic analysis5 Related Literature6 Static and Dynamic Approaches.

We study a low-rationality learning dynamics called probe and adjust. Our emphasis is on its properties in games of information transfer such as the Lewis signaling game or the Bala-Goyal network game. These games fall into the class of weakly better reply games, in which, starting from any action profile, there is a weakly better reply path to a strict Nash equilibrium. We prove that probe and adjust will be close to strict Nash equilibria in this class of games (...) with arbitrarily high probability. In addition, we compare these asymptotic properties to short-run behavior. (shrink)

On at least one of its uses, ‘higher-order evidence’ refers to evidence about what opinions are rationalized by your evidence. This chapter surveys the foundational epistemological questions raised by such evidence, the methods that have proven useful for answering them, and the potential consequences and applications of such answers.

In the debates regarding the ethics of human enhancement, proponents have found it difficult to refute the concern, voiced by certain bioconservatives, that cognitive enhancement violates the autonomy of the enhanced. However, G. Owen Schaefer, Guy Kahane and Julian Savulescu have attempted not only to avoid autonomy-based bioconservative objections, but to argue that cognition-enhancing biomedical interventions can actually enhance autonomy. In response, this paper has two aims: firstly, to explore the limits of their argument; secondly, and more importantly, to develop (...) a more complete understanding of autonomy and its relation to cognitive enhancement. By drawing a distinction between the capacity for autonomy and the exercise and achievement of autonomy and by exploring the possible effects of cognitive enhancement on both competence and authenticity conditions for autonomy, the paper identifies and explains which dimensions of autonomy can and cannot, in principle, be enhanced via direct cognitive interventions. This allows us to draw conclusions regarding the limits of cognitive enhancement as a means for enhancing autonomy. (shrink)

Mass surveillance is a more real threat now than at any time in history. Digital communications and automated systems allow for the collection and processing of private information at a scale never seen before. Many argue that mass surveillance entails a significant loss of privacy. Others dispute that there is a loss of privacy if the information is only encountered by automated systems.This paper argues that automated mass surveillance does not involve a significant loss of privacy. Through providing a definition (...) of informational privacy as a matter of actual access of private information by one who can understand the meaning of that information, it follows that automated systems which lack understanding cannot of themselves diminish privacy. This is not to say that mass surveillance is unproblematic, though - it is deeply problematic. It is just that privacy is not the most significant of these problems. (shrink)

Mainstream political liberalism holds that legal coercion is permissible only if it is based on reasons that all can share, access or accept. But these requirements are subject to well-known problems. I articulate and defend an intelligible reasons requirement as an alternative. An intelligible reason is a reason that all suitably idealized members of the public can see as a reason for the person who offers it according to that person’s own evaluative standards. It thereby permits reasons into public justification (...) that all cannot share, access, or accept, and so contrasts with standard approaches to public justification. The intelligible reasons requirement has two striking implications. First, it severs the connection between public justification and principles of deliberative restraint. Second, it pushes political liberals to appeal to other political processes to publicly justify law, specifically bargaining, adjudication, and social evolution. (shrink)

Hermann Grassmann's Ausdehnungslehre of 1844 and his Lehrbuch der Arithmetik of 1861 are landmark works in mathematics; the former not only developed new mathematical fields but also both contributed to the setting of modern standards of rigor. Their very modernity, however, may obscure features of Grassmann's view of the foundations of mathematics that were not adopted since. Grassmann gave a key role to the learning of mathematics that affected his method of presentation, including his emphasis on making initial assumptions explicit. (...) In order to better understand this less well-known aspect of his work it will help to examine why some commentators have overlooked his theme of unifying logic, pedagogy and foundations, while others have recognised it.

Although Hans Jonas's theory of responsibility has been influential on continental European environmental ethics, his philosophy of life, which seeks to rehabilitate a teleological account of living beings and describe their differing degrees of ‘existential freedom’, is less well-known. In this article, I reconstruct the stages of Jonas's phenomenological account and address the key criticisms levelled at it. I argue that although Jonas's theory is flawed by internal contradictions, these may be rectifiable, and, if so, his philosophy of life could (...) also provide an ontological rationale for a biocentric ethic. I conclude that for these reasons his work deserves greater scholarly attention. (shrink)

Freedom of information requests are increasingly used in sociology, criminology and other social science disciplines to examine government practices and processes. University ethical review boards in Canada have not typically subjected researchers’ FOI requests to independent review, although this may be changing in the United Kingdom and Australia, reflective of what Haggerty calls ‘ethics creep’. Here we present four arguments for why FOI requests in the social sciences should not be subject to formal ethical review by ERBs. These four arguments (...) are: existing, rigorous bureaucratic vetting; double jeopardy; infringement of citizenship rights; and unsuitable ethics paradigm. In the discussion, we reflect on the implications of our analysis for literature on ethical review and qualitative research, and for literature on FOI and government transparency. (shrink)

It seems plausible that there can be “no win” moral situations in which no matter what one does one fails some moral obligation. Is there an epistemic analog to moral dilemmas?

A team of top epistemologists address these and closely related questions from a variety of new, sometimes unexpected, angles. Anyone (...) interested in epistemic dilemmas, the nature of justification and evidential support, higher-order requirements, or suspension of judgment will find a range of useful arguments and fresh ideas in this cutting-edge anthology.
