Advocates of certain paraconsistent logics claim that classical logic provides incorrect norms for reasoning about impossible situations. Some have taken this claim as a sufficient reason to modify classical accounts of consequence. In this paper, I explain and evaluate such an argument based on Graham Priest's fictional story, "Sylvan's Box." I will explain and evaluate an objection to this argument based on a consistent reading of Priest's story offered by Daniel Nolan. However, I will argue that the argument fails for (...) different reasons. It is not the case that classical logic provides incorrect norms for reasoning about impossible situations. I will discuss logical tools, offered by Daniel Nolan, compatible with classical accounts of consequence that allow for non-vacuous reasoning about impossibilities. Finally, I will offer an explanation for seeming tensions between certain classical logic principles and reasoning about impossibilities. (shrink)

The dominance conditional 'If I drink the contents of cup A, I will drink more than if drink the contents of cup B' is true if we know that the first cup contains more than the second. In the first part of the paper, I show that only one kind of theory of indicative conditionals can explain this fact — a Stalnaker-type semantics. In the second part of the paper, I show that dominance conditionals can help explain a long-standing mystery: (...) the question of how one-boxers and two-boxers are guided by conditionals to their respective answers to the Newcomb problem. I will suggest that both implicitly appeal to a decision theoretic principle I will call the Dominance Norm (DN), a principle that connects indicative dominance conditionals with rational courses of action. Finally, I show that DN in combination with a Stalnaker-type theory of indicatives commits us to the two-boxing answer in the Newcomb problem. (shrink)

Counterpossibles are counterfactuals that involve some metaphysical impossibility. Modal normativism is a non-descriptivist account of metaphysical necessity and possibility according to which modal claims, e.g. ‘necessarily, all bachelors are unmarried’, do not function as descriptive claims about the modal nature of reality but function as normative illustrations of constitutive rules and permissions that govern the use of ordinary non-modal vocabulary, e.g. ‘bachelor’. In this paper, I assume modal normativism and develop a novel account of counterpossibles and claims about metaphysical similarity (...) between possible and impossible worlds. I argue that considerations of metaphysical similarity between various impossible worlds and the actual world only require us to tacitly consider how the actual constitutive rules that govern the use of our terms change in order to accommodate the description of some hypothetical impossible scenario. I then argue for my account by raising worries for alternative epistemic and realist accounts of counterpossibles and showing how my account avoids those worries. (shrink)

Ever since the publication of Mansfield Park readers and critics have debated how to understand the novel and particularly its heroine Fanny Price. Some have disliked Fanny, have thought of her as prudish and priggish, and perhaps have preferred Mary Crawford and wished for a different ending to the story. Others have defended Fanny’s virtue, her judgment, and her mind, regarding them as quite superior to the virtue, judgment, and minds of all of the other women in the novel, and (...) all the men too, excepting (perhaps) Edmund. The debate, quite clearly, is about what Jane Austen was up to in a novel with a heroine so different from those in her other novels. The question is unclear in part because the narrator’s voice in Mansfield Park is so much like Mary Crawford’s voice. In her article “Searching for Jane Austen in Mary Crawford,” Emily Auerbach offers us quotations from Mary Crawford and from Jane Austen’s own letters and challenges us to figure out which are which—and it is very difficult. Mary Crawford, like Jane Austen, is frequently sparkling and edgy while Fanny is not, yet Fanny is the star. (shrink)

The core idea of David Armstrong’s combinatorial theory of possibility is attractive. Rearrangement is the key to modality; possible worlds result from scrambling bits and pieces of other possible worlds. Yet I encounter great difficulty when trying to formulate the theory rigorously, and my best attempts are vulnerable to counterexamples. The Leibnizian biconditionals relate possibility and necessity to possible world and true in.

How does science work? _Making Truth: Metaphor in Science_ argues that most laypeople, and many scientists, do not have a clear understanding of how metaphor relates to scientific thinking. With stunning clarity, and bridging the worlds of scientists and nonscientists, Theodore L. Brown demonstrates the presence and the power of metaphorical thought. He presents a series of studies of scientific systems, ranging from the atom to current topics in chemistry and biology such as protein folding, chaperone proteins, and global (...) warming. These case studies provide the basis for far-reaching conclusions about science as an intellectual and social practice and about the nature of scientific truth. (shrink)

Act Utilitarianisms divide into Total and Average versions. Total versions seem to imply Parfit’s “Repugnant Conclusion”. Average versions are proposed in part to avoid the Repugnant Conclusion, but these are subject to “Mere Addition” arguments as detailed by Hudson in “The Diminishing Marginal Value of Happy People”. Thus, various intermediate versions of utilitarianism, such as the one investigated by Hurka in “Value and Population Size”, take on interest. But Hudson argues that such compromise theories are subject to the mere addition (...) arguments, and are therefore no improvement over Average Utilitarianism. I disagree: some such compromise solutions escape Hudson’s Mere Addition arguments. (shrink)

Calls to hold artificial intelligence to account are intensifying. Activists and researchers alike warn of an “accountability gap” or even a “crisis of accountability” in AI. Meanwhile, several prominent scholars maintain that accountability holds the key to governing AI. But usage of the term varies widely in discussions of AI ethics and governance. This chapter begins by disambiguating some different senses and dimensions of accountability, distinguishing it from neighboring concepts, and identifying sources of confusion. It proceeds to explore the idea (...) that AI operates within an accountability gap arising from technical features of AI as well as the social context in which it is deployed. The chapter also evaluates various proposals for closing this gap. I conclude that the role of accountability in AI ethics and governance is vital but also more limited than some suggest. Accountability’s primary job description is to verify compliance with substantive normative principles—once those principles are settled. Theories of accountability cannot ultimately tell us what substantive standards to account for, especially when norms are contested or still emerging. Nonetheless, formal mechanisms of accountability provide a way of diagnosing and discouraging egregious wrongdoing even in the absence of normative agreement. Providing accounts can also be an important first step toward the development of more comprehensive regulatory standards for AI. (shrink)

Sometimes we give truth-conditions for sentences of a discourse in other terms. According to Agustín Rayo, when doing so it is sometimes legitimate to use the terms of that very discourse, so long as the terms do not occur in the truth-conditions themselves. I argue that giving truth-conditions in this "outscoping" way prevents one from answering "discourse threat" (for example, the threat of indeterminacy).

What is the significance of hermeneutics at the intersections of ethics, politics and the arts and humanities? In this book, George -/- - Discusses how hermeneutics offers ways to develop an ethics - Makes the case for the relevance of contemporary hermeneutics for current scholarly discussions of responsibility within continental European philosophy - Contributes a new, ethically inflected approach to current debate within post-Gadamerian hermeneutics - Extends his analysis to the practice of living and covers animals, art, literature and translation (...) -/- Few topics have received broader attention within contemporary philosophy than that of responsibility. Theodore George makes a novel case for a distinctive sense of responsibility at stake in the hermeneutical experiences of understanding and interpretation. -/- George argues for the significance of this hermeneutical responsibility in the context of our relations with things, animals and others, as well as political solidarity and the formation of solidarities through the arts, literature and translation.

Under the influence of the mysterious Ammonius Saccas, Plotinus conceived a desire to learn Persian and Indian philosophy firsthand. This led him to a romantic participation in the emperor Gordian's ill-fated Persian expedition. He managed to escape to Antioch and two years later began teaching in Rome.1 It is unlikely he was vouchsafed any contact with Hinduism or Buddhism,2 but the parallels between his thought and especially Buddhist philosophy are striking. The parallels with Buddhism are closer than with Hinduism since (...) Buddhism worked with three rather than two levels or substructures of reality,3 yet the Hindu connection has been more frequently explored by Neoplatonist scholars than the Buddhist.4... (shrink)

Posner [6] has shown, by a nonuniform proof, that every ▵ 0 2 degree has a complement below 0'. We show that a 1-generic complement for each ▵ 0 2 set of degree between 0 and 0' can be found uniformly. Moreover, the methods just as easily can be used to produce a complement whose jump has the degree of any real recursively enumerable in and above $\varnothing'$ . In the second half of the paper, we show that the complementation (...) of the degrees below 0' does not extend to all recursively enumerable degrees. Namely, there is a pair of recursively enumerable degrees a above b such that no degree strictly below a joins b above a. (This result is independently due to S. B. Cooper.) We end with some open problems. (shrink)

In Republic V, Plato makes the astonishing claim that knowledge is a different and independent power from belief, in the way, for example, that sight differs from hearing. I will argue that this is a fundamentally different conception of knowledge than the, also Platonic, conception of knowledge as 'true belief with an account'. I examine the reasons why Plato holds this position, and the ontology and epistemology which sustain its claims.

There is growing support for the view that social categories like men and women refer to “objective types” (Haslanger 2000, 2006, 2012; Alcoff 2005). An objective type is a similarity class for which the axis of similarity is an objective rather than nominal or fictional property. Such types are independently real and causally relevant, yet their unity does not derive from an essential property. Given this tandem of features, it is not surprising why empirically-minded researchers interested in fighting oppression and (...) marginalization have found this ontological category so attractive: objective types have the ontological credentials to secure the reality (and thus political representation) of social categories, and yet they do not impose exclusionary essences that also naturalize and legitimize social inequalities. This essay argues that, from the perspective of these political goals of fighting oppression and marginalization, the category of objective types is in fact a Trojan horse; it looks like a gift, but it ends up creating trouble. I argue that objective type classifications often lack empirical adequacy, and as a result they lack political adequacy. I also provide, and in reference to the normative goals described above, several arguments for preferring a social ontology of natural kinds with historical essences. (shrink)

The kinds of real or natural kinds that support explanation and prediction in the social sciences are difficult to identify and track because they change through time, intersect with one another, and they do not always exhibit their properties when one encounters them. As a result, conceptual practices directed at these kinds will often refer in ways that are partial, equivocal, or redundant. To improve this epistemic situation, it is important to employ open-ended classificatory concepts, to understand when different research (...) programs are tracking the same real kind, and to maintain an ongoing commitment to interact causally with real kinds to focus reference on those kinds. A tempting view of these non-idealized epistemic conditions should be avoided: that they signal an ontological structure of the social world so plentiful that it would permit ameliorated classificatory schemes to achieve their normative aims regardless of whether they defer to real-kind classificatory schemes. To ground these discussions, the essay appeals to an overlooked convergence in the systematic naturalistic frameworks of Richard Boyd and Ruth Millikan. (shrink)

This paper presents and defends an argument for the conclusion that a personal afterlife in the absence of any sort of body at all is not conceptually possible. The main idea behind the argument is that there would be no way for the identities of people in a bodiless state to be established, either by others or by themselves. The argument raises a significant challenge to explaining just how someone in a totally disembodied afterlife could ever be identified—a challenge that (...) has yet to be met. (shrink)

There is broad agreement among social researchers and social ontologists that the project of dividing humans into social kinds should be guided by at least two methodological commitments. First, a commitment to what best serves moral and political interests, and second, a commitment to describing accurately the causal structures of social reality. However, researchers have not sufficiently analyzed how these two commitments interact and constrain one another. In the absence of that analysis, several confusions have set in, threatening to undermine (...) shared goals for the responsible modeling of social kinds of humans. This essay first explains the source and substance of these confusions. Then, by distinguishing different value-laden investigative questions into the classification of social kinds of humans, it sets out specific relations of dependence and constraint between empirically-driven investigations and value-driven investigations into social kinds of humans. The result is a more detailed and fruitful framework for thinking about the classification of social kinds that respects both normative interests and mind-independent causal regularities. (shrink)

Religion is a racialized category, even when race is not explicitly mentioned. In Modern Religion, Modern Race Theodore Vial argues that because the categories of religion and race are rooted in the post-Enlightenment project of reimagining what it means to be human, we cannot simply will ourselves to stop using them. Only by acknowledging that religion is already racialized can we begin to understand how the two concepts are intertwined and how they operate in our modern world.It has become (...) common to argue that the category religion is not universal, or even very old, but is a product of Europe's Enlightenment modernization. Equally common is the argument that religion is not an innocent category of analysis, but is implicated in colonial regimes of control and as such plays a role in Europe's process of identity construction of itself and of non-European.

Creating android and humanoid robots to furnish companionship in the nursing care of older people continues to attract substantial development capital and research. Some people object, though, that machines of this kind furnish human–robot interaction characterized by inauthentic relationships. In particular, robotic and artificial intelligence (AI) technologies have been charged with substituting mindless mimicry of human behaviour for the real presence of conscious caring offered by human nurses. When thus viewed as deceptive, the robots also have prompted corresponding concerns regarding (...) their potential psychological, moral, and spiritual implications for people who will be interacting socially with these machines. The foregoing objections and concerns can be assessed quite differently, depending upon ambient religious beliefs or metaphysical presuppositions. The complaints may be set aside as unnecessary, for example, within religious traditions for which even current robots can be viewed as presenting spiritual aspects. Elsewhere, technological cultures may reject the complaints as expression of outdated superstition, holding that the machines eventually will enjoy a consciousness described entirely in materialist and behaviourist terms. While recognizing such assessments, the authors of this essay propose that the heart of the foregoing objections and concerns may be evaluated, in part, scientifically – albeit with a conclusion recommending fundamental revisions in AI modelling of human mental life. Specifically, considerations now favour introduction of AI models using interactive classical and quantum computation. Without this change, the answer to the essay's title question arguably is ‘no’ – with it, the answer plausibly becomes ‘maybe’. Either outcome holds very interesting implications for nurses.

I argue that we can accept modal normativism—a view that the function of modal claims is to express semantic rules—while also accepting possible worlds semantics. I argue that by keeping the metaphysical insights of normativism at the level of metasemantics—i.e., at the level of accounts of what metaphysically explains facts about the meaning of modal claims—it is open to the normativist to wholeheartedly accept possible worlds semantics.

Nature, and the place of humans within it, has again become a topic of much discussion. The tendency of biblical scholars has been to describe the human being in terms that set it apart from nature. More recently, ecological concerns have impelled biblical scholars to rethink their position. This has caused them to reevaluate the nature of humanity and to construe the human being not as standing above or at the center of nature, but as being part of nature.
