I argue that in the Phaedo, Plato maintains that the soul is located in space and is capable of locomotion and of interacting with the body through contact. Numerous interpreters have dismissed these claims as merely metaphorical, since they assume that as an incorporeal substance, the soul cannot possess spatial attributes. But careful examination of how Plato conceives of the body throughout his corpus reveals that he does not distinguish it from the soul in terms of spatiality. Furthermore, assigning spatial (...) attributes to the soul plays an important role in Plato’s account of the relation of body and soul. (shrink)

One of the ways in which Plato has captured the popular imagination is with the claim that the philosopher can feel erôs, passionate love, for the objects of knowledge. Why should Plato make this claim? In this chapter, I explore Plato’s treatment of philosophical erôs along three dimensions. First, I consider the source of philosophical erôs. I argue that it is grounded in our mortality and imperfection, which give rise to a desire for immortality and the immortal. Second, I turn (...) to the object of philosophical erôs. I suggest that it is an arresting response to beauty, through which we come to value the ideal properties of the forms. Finally, I address the nature of erôs. I claim that it is a focusing desire, that overrides other concerns and causes us to overwhelmingly focus on its object. I conclude the chapter by considering the problem Vlastos famously raises for Plato’s account of erôs: can it do justice to disinterested, interpersonal love? In agreement with Vlastos, I claim that one who comes to grasp the forms will cease to feel interpersonal love; however, I also suggest that erôs can give rise to philia, beneficent concern with the wellbeing of others.

This paper analyzes the apraxia argument in Cicero’s Academica. It proposes that the argument assumes two modes: the evidential mode maintains that skepticism is false, while the pragmatic claims that it is disadvantageous. The paper then develops a tension between the two modes, and concludes by exploring some differences between ancient and contemporary skepticism.

While artificial intelligence (AI) is increasingly applied for decision-making processes, ethical decisions pose challenges for AI applications. Given that humans cannot always agree on the right thing to do, how would ethical decision-making by AI systems be perceived and how would responsibility be ascribed in human-AI collaboration? In this study, we investigate how the expert type (human vs. AI) and level of expert autonomy (adviser vs. decider) influence trust, perceived responsibility, and reliance. We find that participants consider humans to be (...) more morally trustworthy but less capable than their AI equivalent. This shows in participants’ reliance on AI: AI recommendations and decisions are accepted more often than the human expert’s. However, AI team experts are perceived to be less responsible than humans, while programmers and sellers of AI systems are deemed partially responsible instead. (shrink)

This paper defends an intellectualist interpretation of Diotima’s speech in Plato’s Symposium. I argue that Diotima’s purpose, in discussing the lower lovers, is to critique their erōs as aimed at a goal it can never secure, immortality, and as focused on an inferior object, themselves. By contrast, in loving the form of beauty, the philosopher gains a mortal sort of completion; in turning outside of himself, he also ceases to be preoccupied by his own incompleteness.

Increasingly complex and autonomous systems require machine ethics to maximize the benefits and minimize the risks to society arising from the new technology. It is challenging to decide which type of ethical theory to employ and how to implement it effectively. This survey provides a threefold contribution. First, it introduces a trimorphic taxonomy to analyze machine ethics implementations with respect to their object (ethical theories), as well as their nontechnical and technical aspects. Second, an exhaustive selection and description of relevant (...) works is presented. Third, applying the new taxonomy to the selected works, dominant research patterns, and lessons for the field are identified, and future directions for research are suggested. (shrink)

According to Plato's successors, assimilation to god (homoiosis theoi) was the end (telos) of the Platonic system. There is ample evidence to support this claim in dialogues ranging from the Symposium through the Timaeus. However, the Philebus poses a puzzle for this conception of the Platonic telos. On the one hand, Plato states that the gods are beings beyond pleasure while, on the other hand, he argues that the best human life necessarily involves pleasure. In this paper, I argue that (...) the solution to this puzzle lies in the fact that the processes by which we assimilate to god, learning and becoming virtuous, are restitutive and hence pleasant. Thus, the reason why the best human life necessarily involves pleasure is that we can never become fully divine and perfect, but must constantly strive to become like the divine, through pleasureful restitutive processes. In this paper, I also provide a close examination and taxonomy of the different models that Plato presents throughout his corpus of assimilation to god. -/- Note: "Fleeing the Divine" (Philebus: Selected Papers from the VIII Symposium Platonicum) is an earlier, shorter version of this paper.

In this chapter, I offer an overview of current scholarly debates on Plato's Lysis. I also argue for my own interpretation of the dialogue. In the Lysis, Socrates argues that all love is motivated by the desire for one’s own good. This conclusion has struck many interpreters as unattractive, so much so that some attempt to reinterpret the dialogue, such that it either does not offer an account of interpersonal love, or that it offers an account on which love is, (...) in fact, an other-regarding state. Others, notably Vlastos, criticize Socrates’ theory as implausibly and repellently egoistic. I maintain, against the first group, that Socrates is indeed offering an egoistic theory of love. I argue, against the second, that, while Socrates’ theory may be repellent, it possesses considerable explanatory power and avoids certain weaknesses which infect contemporary approaches to love.

In this paper, I offer a new interpretation of Aristophanes’ speech in Plato’s Symposium. Though Plato deliberately draws attention to the significance of Aristophanes’ speech in relation to Diotima’s (205d-206a, 211d), it has received relatively little philosophical attention. Critics who discuss it typically treat it as a comic fable, of little philosophical merit (e.g. Guthrie 1975, Rowe 1998), or uncover in it an appealing and even romantic treatment of love that emphasizes the significance of human individuals as love-objects to be (...) valued for their own sakes (e.g. Dover 1966, Nussbaum 1986). Against the first set of interpreters, I maintain that Aristophanes’ speech is of the utmost philosophical significance to the dialogue; in it, he sets forth a view of eros as a state of lack and a corresponding desire for completion, which is the starting-point for Diotima’s subsequent analysis. Against the second, I argue that Aristophanes’ speech contains a profoundly pessimistic account of eros. Far from being an appreciative response to the individuality of the beloved, eros, for Aristophanes, is an irrational urge, incapable of satisfaction. It is this irrationality that precludes Aristophanes’ lovers from achieving the partial satisfaction of erotic desire that is open to their Socratic counterparts through their relationship to the forms.

In the Protagoras, Socrates argues that what appears to be akrasia is, in fact, the result of a hedonic illusion: proximate pleasures appear greater than distant ones. On the face of it, his account is puzzling: why should proximate pleasures appear greater than distant ones? Certain interpreters argue that Socrates must be assuming the existence of non-rational desires that cause proximate pleasures to appear inflated. In this paper, I argue that positing non-rational desires fails to explain the hedonic error. However, (...) careful consideration of Socrates’ treatment of appearances reveals that he is not without resources to explain the illusion. I argue that in the Protagoras, appearances are imagistic mental representations that appear true but tend to be false. I suggest that proximate pleasures produce inflated hedonic predictions because we represent them more vividly than distant ones, yielding greater anticipatory pleasure which causes us to overestimate their magnitude.

In dialogues ranging from the Symposium to the Timaeus, Plato appears to propose that the philosopher’s grasp of the forms may confer immortality upon him. Whatever can Plato mean in making such a claim? What does he take immortality to consist in, such that it could constitute a reward for philosophical enlightenment? And how is this proposal compatible with Plato’s insistence throughout his corpus that all soul, not just philosophical soul, is immortal? In this chapter, I pursue these questions by (...) applying the distinction between general and earned immortality to the Phaedo and the Symposium. I argue that, while Plato attributes general immortality to all soul in the Phaedo, in the Affinity Argument, he proposes that the philosopher’s soul can achieve earned immortality through contemplating forms. It is this form of immortality that Plato claims is unavailable to humankind in the flux passage of the Symposium. At the same time, in the ascent passage, he holds out the possibility – albeit with significant reservations – that the philosopher’s soul may transcend its humanity and achieve earned immortality through its communion with the form.

This chapter examines Plato's moral psychology in the Phaedrus. It argues against interpreters such as Burnyeat and Nussbaum that Plato's treatment of the soul is increasingly pessimistic: reason's desire to contemplate is at odds with its obligation to rule the soul, and psychic harmony can only be secured by violently suppressing the lower parts of the soul.

In this paper, I explore parallels between philosophical and tyrannical eros in Plato's Republic. I argue that in arguing that reason experiences eros for the forms, Plato introduces significant tensions into his moral psychology.

Introduction to a volume on Hegel, asking why his thought continues to be relevant today.

In the United States today, much interpersonal racism is driven by corrupt forms of self-preservation. Drawing from Jean- Jacques Rousseau, I refer to this as self-love racism. The byproduct of socially-induced racial anxieties and perceived threats to one’s physical or social wellbeing, self-love racism is the protective attachment to the racialized dimensions of one’s social status, wealth, privilege, and/or identity. Examples include police officer related shootings of unarmed Black Americans, anti-immigrant sentiment, and the resurgence of unabashed white supremacy. This form (...) of racism is defined less by the introduction of racism into the world and more on the perpetuation of racially unjust socioeconomic and political structures. My theory, therefore, works at the intersection of the interpersonal and structural by offering an account of moral complacency in racist social structures. My goal is to reorient the directionality of philosophical work on racism by questioning the sense of innocence at the core of white ways-of-being. (shrink)

Homology is a biological sameness relation that is purported to hold in the face of changes in form, composition, and function. In spite of the centrality and importance of homology, there is no consensus on how we should understand this concept. The two leading views of homology, the genealogical and developmental accounts, have significant shortcomings. We propose a new account, the hierarchical-dependency account of homology, which avoids these shortcomings. Furthermore, our account provides for continuity between special, general, and serial homology.

Conwy Lloyd Morgan (1852–1936) is widely regarded as the father of modern comparative psychology. Yet, Morgan initially had significant doubts about whether a genuine science of comparative psychology was even possible, only later becoming more optimistic about our ability to make reliable inferences about the mental capacities of non-human animals. There has been a fair amount of disagreement amongst scholars of Morgan’s work about the nature, timing, and causes of this shift in Morgan’s thinking. We argue that Morgan underwent two (...) quite different shifts of attitude towards the proper practice of comparative psychology. The first was a qualified acceptance of the Romanesian approach to comparative psychology that he had initially criticized. The second was a shift away from Romanes’ reliance on systematizing anecdotal evidence of animal intelligence towards an experimental approach, focused on studying the development of behaviour. We emphasize the role of Morgan’s evolving epistemological views in bringing about the first shift – in particular, his philosophy of science. We emphasize the role of an intriguing but overlooked figure in the history of comparative psychology in explaining the second shift, T. Mann Jones, whose correspondence with Morgan provided an important catalyst for Morgan’s experimental turn, particularly the special focus on development. We also shed light on the intended function of Morgan’s Canon, the methodological principle for which Morgan is now mostly known. The Canon can only be properly understood by seeing it in the context of Morgan’s own unique experimental vision for comparative psychology. (shrink)

The developmental properties of organisms play important roles in the generation of variation necessary for evolutionary change. But how can individual development steer the course of evolution? To answer this question, we introduce developmental channeling as a disposition of individual organisms that shapes their possible developmental trajectories and evolutionary dappling as an evolutionary outcome in which the space of possible organismic forms is dappled—it is only partially filled. We then trace out the implications of the channeling-dappling framework for contemporary debates (...) in the philosophy of evolution, including evolvability, reciprocal causation, and the extended evolutionary synthesis.

Wars and crises worldwide force millions of people to flee and seek refuge, often outside their countries of origin. What moral responsibilities do states have towards refugees? In this Ethical Annotation, Dr Jos Philips and his co-authors zoom in on the responsibilities of EU countries. They consider arguments in favour of and against admitting refugees and argue that EU countries must do at least at much as they can do at little cost, and perhaps even more.

This paper presents results found through searching publicly available U.S. data sources for information about how to handle incidental fndings (IF) in human subjects research, especially in genetics and genomics research, neuroimaging research, and CT colonography research.

Our analysis of these documents showed that there is very (...) little public guidance available for researchers as to how to deal with incidental fndings. Moreover, the guidance available is not consistent. (shrink)

This essay explores the intersection of racism, racial embodiment theory and the recent hostility aimed at immigrants and foreigners in the United States, especially the targeting of people of Latin American descent and Latino/as. Anti-immigrant and anti-foreigner sentiment is racist. It is the embodiment of racial privilege for those who wield it and the materiality of racial difference for those it is used against. This manifestation of racial privilege and difference rests upon a redrawing of the color line that is (...) meant towards preserving exclusive categories of political membership. The charge of racism, however, is elided by the fact that this hostility takes the form of a specious embracement of law and lawfulness. “Illegal” in this sense not only captures the actions of those who enter the United States through clandestine or informal means, but, in light of the history of immigration and citizen- ship law, the term operates as a racial trope that designates non-white status, thus marginalizing and alienating certain immigrants from ongoing nation-formation processes. I explain the source for anti-immigrant hostility in the United States, which I take to be connected to the longevity of white normativity as the basis for American identity. I then critically assess how the idea of national belonging is crucial to the perpetuation of white-ways-of-being, especially when citizenship has historically been a venue for the embodiment of racial and even colonial privilege. I conclude by posing several questions about the nature of racial identities and racism that suggest new avenues for further research on racial embodiment in a “postracial” era. pp. 65–90. (shrink)

This work explores the increasing militarization of borders throughout the world, particularly the United States border with Mexico. Rather than further rhetoric of "border security," this work views increases in guards, technology and the building of walls as militarized action. The goal of this essay is to place the onus upon states to justify their actions at borders in ways that do not appeal to tropes of terrorism. This work then explores how a logic of security infiltrates philosophical discussions of (...) "the right to exclude," thereby curtailing the ability to see borders in any other way than as a locale that must be militarized. Specifically, I analyze the work of Michael Blake and his juridical theory of immigration restrictions. I argue that his work necessitates the walling of borders and removal of those who create new obligations for current members of existing political institutions. (shrink)

To deserve credit for doing what is morally right, we must act from the right kinds of motives. Acting from the right kinds of motives involves responding both to the morally relevant reasons, by acting on these considerations, and to the morally relevant individuals, by being guided by appropriate attitudes of regard for them. Recent theories of the right kinds of motives have tended to prioritize responding to moral reasons. I develop a theory that instead prioritizes responding to individuals (through (...) appropriate attitudes of regard for them) and argue that it better accounts for the basic features of the right kinds of motives – what we most fundamentally care about in judging whether persons deserve moral credit.

Fitness plays many roles throughout evolutionary theory, from a measure of populations in the wild to a central element in abstract theoretical presentations of natural selection. It has thus been the subject of an extensive philosophical literature, which has primarily centered on the way to understand the relationship between fitness values and reproductive outcomes. If fitness is a probabilistic or statistical quantity, how is it to be defined in general theoretical contexts? How can it be measured? Can a single conceptual (...) model for fitness be offered that applies in all biological cases, or must fitness measures be case-specific? Philosophers have explored these questions over the last several decades, largely in the context of an influential definition of fitness proposed in the late 1970s: the propensity interpretation. This interpretation as first described undeniably suffers from significant difficulties, and debate regarding the tenability of amendments and alternatives to it remains unsettled. (shrink)

Suppose you think that whether you believe some proposition A at some future time t might have a causal influence on whether A is true. For instance, maybe you think a woman can read your mind, and either (1) you think she will snap her fingers shortly after t if and only if you believe at t that she will, or (2) you think she will snap her fingers shortly after t if and only if you don't believe at t (...) that she will. Let A be the proposition that she snaps her fingers shortly after t. In case (1), theoretical rationality seems to leave it open whether you should believe A or not. Perhaps, for all it has to say, you could just directly choose whether to believe A. David Velleman seems to be committed to something close to that, but his view has been unpopular. In case (2), you seem to be in a theoretical dilemma, a situation where any attitude you adopt toward A will be self-undermining in a way that makes you irrational. Such theoretical dilemmas ought to be impossible, just as genuine moral dilemmas ought to be impossible, but it is surprisingly hard to show that they are (perhaps because they aren't). I study cases analogous to (1) and (2) in a probabilistic framework where degrees of belief rather than all-or-nothing beliefs are taken as basic. My principal conclusions are that Velleman's view is closer to the truth than it is generally thought to be, that case (2) type theoretical dilemmas only arise for hyperidealised agents unlike ourselves, and that there are related cases that can arise for agents like us that are very disturbing but might not quite amount to theoretical dilemmas.

There is a puzzle about the very possibility of foreseen but unintended side effects, and solving this puzzle requires us to revise our basic picture of the structure of practical deliberation. The puzzle is that, while it seems that we can rationally foresee, but not intend, bringing about foreseen side effects, it also seems that we rationally must decide to bring about foreseen side effects and that we intend to do whatever we decide to do. I propose solving this puzzle (...) by rejecting the idea that we intend to do whatever we decide to do. My solution involves taking account of the underappreciated role that qualified intentions play in deliberation. I also argue that this solution fares better than those that instead reject the idea that we rationally must decide to bring about foreseen side effects, for these solutions are committed to rejecting the even more compelling idea that decisions rationally serve as the conclusions of practical deliberation.

This short article lays the foundation for a theory of migratorial disobedience and explains how pro-border advocates fetishize immigration law.

This essay is about the loss of voice. It is about the ways in which the act of writing philosophy often results in an alienating and existentially meaningless experience for many budding philosophers, particularly those who wish to think from their racialized and gendered identities in professional academic philosophy.

A critical review essay, this work explains the methodological, material, and ideological reasons for why "diversity" initiatives in philosophy face an up-hill battle.

The new immigration legislation will not achieve its ostensible goal. The criteria it proposes for new immigrants thinly conceal its racist motivations.

The compelling, widely-accepted Satisfaction-is-Truth Principle says that if S wants p, then S has a desire that's satisfied in exactly the worlds where p is true. We reject the Principle; an agent may want p without having a desire that's satisfied when p obtains in any old way. Other theorists who reject the Principle rely on contested intuitions about when agents get what they want. We instead appeal to—and shed new light on—the dispositional role of desire.

The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that (...) avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. (shrink)

Human nature is frequently evoked to characterize our species and describe how it differs from others. But how should we understand this concept? What is the nature of a species? Some take our nature to be an essence and argue that because humans lack an essence, they also lack a nature. Others argue for non-essentialist ways of understanding human nature, which usually aim to provide criteria for sorting human traits into one of two bins, the one belonging to our nature (...) and the other outside our nature. This Element argues that both the essentialist and trait bin approaches are misguided. Instead, the author develops a trait cluster account of human nature, which holds that human nature is based on the distribution of our traits over our (actual and possible) life histories. One benefit of this account is that it aligns human nature with the human sciences, rendering the central concern of the human sciences to be the study of human nature. (shrink)

The aim of this paper is to explain why creativity is an artistic merit. Artworks and non-artworks can both be creative. But creativity does not help make many other creative things good of their kind. A creative explanation is not a better explanation in virtue of being creative. Why, then, is a creative artwork a better artwork in virtue of being creative? Understanding this will give us a better understanding of the nature of artistic merit. The approach adopted in this (...) paper is as follows. First, I say what creativity is and what an artistic merit is. Second, I identify reasons to doubt that creativity is an artistic merit. A good explanation of the merit of creativity should address these doubts. Third, I develop a theory of artistic merit that appeals to the final value of acting excellently – for example, virtuously or skilfully. Finally, I argue that this enables us to explain why creativity is an artistic merit. This account also enables us to argue that artistic merits give some things final value, and not merely instrumental value. It also provides reason to believe that ethical qualities of artworks enhance their artistic merit for the same reason creativity does. (shrink)

The ongoing explosion of interest in artificial intelligence is fueled in part by recently developed techniques in machine learning. Those techniques allow automated systems to process huge amounts of data, utilizing mathematical methods that depart from traditional statistical approaches, and resulting in impressive advancements in our ability to make predictions and uncover correlations across a host of interesting domains. But as is now widely discussed, the way that those systems arrive at their outputs is often opaque, even to the experts (...) who design and deploy them. Is it morally problematic to make use of opaque automated methods when making high-stakes decisions, like whether to issue a loan to an applicant, or whether to approve a parole request? Many scholars answer in the affirmative. However, there is no widely accepted explanation for why transparent systems are morally preferable to opaque systems. We argue that the use of automated decision-making systems sometimes violates duties of consideration that are owed by decision-makers to decision-subjects, duties that are both epistemic and practical in character. Violations of that kind generate a weighty consideration against the use of opaque decision systems. In the course of defending our approach, we show that it is able to address three major challenges sometimes leveled against attempts to defend the moral import of transparency in automated decision-making.

The levels of selection debate is generally taken to be a debate about how natural selection can occur at the various levels of biological organization. In this paper, we argue that questions about levels of selection should be analyzed separately from questions about levels of organization. In the deflationary proposal we defend, all that is necessary for multilevel selection is that there are cases in which particles are nested in collectives, and that both the collectives and the particles that compose (...) them each separately undergo natural selection. We argue that adopting this deflationary account helps to disentangle the levels of selection and the levels of organization, and thereby contributes to advancing the levels of selection debate.

Organismal death is foundational to the evolution of life, and many biological concepts such as natural selection and life history strategy are so fashioned only because individuals are mortal. Organisms, irrespective of their organization, are composed of basic functional units—cells—and it is our understanding of cell death that lies at the heart of most general explanatory frameworks for organismal mortality. Cell death can be exogenous, arising from transmissible diseases, predation, or other misfortunes, but there are also endogenous forms of death (...) that are sometimes the result of adaptive evolution. These endogenous forms of death—often labeled programmed cell death, PCD—originated in the earliest cells and are maintained across the tree of life. Here, we consider two problematic issues related to PCD (and cell mortality generally). First, we trace the original discoveries of cell death from the nineteenth century and place current conceptions of PCD in their historical context. Revisions of our understanding of PCD demand a reassessment of its origin. Our second aim is thus to structure the proposed origin explanations of PCD into coherent arguments. In our analysis we argue for the evolutionary concept of PCD and the viral defense-immunity hypothesis for the origin of PCD. We suggest that this framework offers a plausible account of PCD early in the history of life, and also provides an epistemic basis for the future development of a general evolutionary account of mortality.

This article argues the following points. The Hobbesian hypothesis, which we define as the claim that all people are better off under state authority than they would be outside of it, is an empirical claim about all stateless societies. It is an essential premise in most contractarian justifications of government sovereignty. Many small-scale societies are stateless. Anthropological evidence from them provides sufficient reason to doubt the truth of the hypothesis, if not to reject it entirely. Therefore, contractarian theory has not (...) done what it claims to do: it has not justified state sovereignty to each person subject to it by demonstrating that they benefit from that authority. To be justified in contractarian terms, states have to do something to improve the living standards of disadvantaged people under their rule. (shrink)
