Region R Question: How many objects — entities, things — are contained in R? Ignore the empty space. Our question might better be put, 'How many material objects does R contain?' Let's stipulate that A, B and C are metaphysical atoms: absolutely simple entities with no parts whatsoever besides themselves. So you don't have to worry about counting a particle's top half and bottom half as different objects. Perhaps they are 'point-particles', with no length, width or breadth. Perhaps they are (...) extended in space without possessing spatial parts (if that is possible). Never mind. We stipulate that A, B and C are perfectly simple. We also stipulate that they are connected as follows. A and B are stuck together in such a way that when a force is applied to one of them, they move together 'as a unit'. Moreover, the two of them together exhibit behavior that neither would exhibit on its own — Perhaps they emit a certain sound, or glow in the dark — whereas C is.. (shrink)

This paper takes up a neglected problem for metaethical noncognitivism: the characterization of the acceptance states for agent-centered normative theories like Rational Egoism. If Egoism is a coherent view, the non-cognitivist needs a coherent acceptance state for it. This can be provided, as Dreier and Gibbard have shown. But those accounts fail when generalized, assigning the same acceptance state to normative theories that are clearly distinct, or assigning no acceptance state to theories that look to be intelligible. The paper makes (...) the case for this and then asks: What should we conclude if the problem cannot be solved? We might conclude that since Egoism is clearly a coherent view, the argument amounts to a refutation of noncognitivism. But we suggest another possibility. There is, on reflection, something incoherent, or at least odd, in standard formulations of Egoism; noncognitivism predicts this and so provides an intriguing explanation for this fact. (shrink)

According to one sort of epistemic relativist, normative epistemic claims (e.g., evidence E justifies hypothesis H) are never true or false simpliciter, but only relative to one or another epistemic system. In chapter 6 of Fear of Knowledge, Paul Boghossian objects to this view on the ground that its central notions cannot be explained, and that it cannot account for the normativity of epistemic discourse. This paper explores how the dogged relativist might respond.

Gideon Rosen and Robert Schwartzkopff have independently suggested (variants of) the following claim, which is a varian of Hume's Principle: -/- When the number of Fs is identical to the number of Gs, this fact is grounded by the fact that there is a one-to-one correspondence between the Fs and Gs. -/- My paper is a detailed critique of the proposal. I don't find any decisive refutation of the proposal. At the same time, it has some consequences which (...) many will find objectionable. (shrink)

Childhood looms large in our understanding of human life as it is a phase through which all adults have passed. Childhood is foundational to the development of selfhood, the formation of interests, values and skills and to the lifespan as a whole. Understanding what it is like to be a child, and what differences childhood makes, are essential for any broader understanding of the human condition. The Routledge Handbook of the Philosophy of Childhood and Children is an outstanding reference source (...) to the key topics, problems and debates in this exciting subject and is the first collection of its kind. Comprising over thirty chapters by a team of international contributors the Handbook is divided into five parts: ¿ Being a child ¿ Childhood and moral status ¿ Parents and children ¿ Children in society ¿ Children and the state. Questions covered include: What is a child? Is childhood a uniquely valuable state, and if so why? Can we generalize about the goods of childhood? What rights do children have, and are they different from adults¿ rights? What gives people a right to parent? What role, if any, ought biology to play in determining who has the right to parent a particular child? What kind of rights can parents legitimately exercise over their children? What roles do relationships with siblings and friends play in the shaping of childhoods? How should we think about sexuality and disabilility in childhood, and about racialised children? How should society manage the education of children, and what values should inform such practices? What is a good school? How are children¿s lives affected by being taken into social care? The Routledge Handbook of the Philosophy of Childhood and Children is essential reading for students and researchers in philosophy of childhood, political philosophy and ethics as well as those in related disciplines such as education, psychology, sociology, social policy, law, social work, youth work, neuroscience and anthropology.

The family poses problems for liberal understandings of social justice, because of the ways in which it bestows unearned privileges. This is particularly stark when we consider inter-generational inequality, or ‘class fate’ – the ways in which inequality is transmitted from one generation to the next, with the family unit ostensibly a key conduit. There is a recognized tension between the assumption that families should as far as possible be autonomous spheres of decision-making, and the assumption that we should as (...) far as possible equalize the life chances of all children, regardless of background. In this article I address this tension by way of recent liberal egalitarian literature, and consideration of the different dimensions of class fate. I argue, firstly, that the tension may not be of the a priori nature which liberals have tended to identify – and secondly, that as well as distributive and recognition-based aspects, the notion of contributive justice provides a particularly illuminating way of analyzing what is wrong about class fate, and the role of the family in promoting it.

Episodic memory (memories of the personal past) and prospecting the future (anticipating events) are often described as mental time travel (MTT). While most use this description metaphorically, we argue that episodic memory may allow for MTT in at least some robust sense. While episodic memory experiences may not allow us to literally travel through time, they do afford genuine awareness of past-perceived events. This is in contrast to an alternative view on which episodic memory experiences present past-perceived events as mere (...) intentional contents. Hence, episodic memory is a way of coming into experiential contact with, or being again aware of, what happened in the past. We argue that episodic memory experiences depend on a causal-informational link with the past events being remembered, and that, assuming direct realism about episodic memory experiences, this link suffices for genuine awareness. Since there is no such link in future prospection, a similar argument cannot be used to show that it also affords genuine awareness of future events. Constructivist views of memory might challenge the idea of memory as genuine awareness of remembered events. We explain how our view is consistent with both constructivist and anti-causalist conceptions of memory. There is still room for an interpretation of episodic memory as enabling genuine awareness of past events, even if it involves reconstruction. (shrink)

Reid argues that Hume’s claim that justice is an artificial virtue is inconsistent with the fact that gratitude is a natural sentiment. This chapter shows that Reid’s argument succeeds only given a philosophy of mind and action that Hume rejects. Among other things, Reid assumes that one can conceive of one of a pair of contradictories only if one can conceive of the other—a claim that Hume denies. So, in the case of justice, the disagreement between Hume and Reid is, (...) at bottom, a disagreement over their respective conceptions of how the human mind works at its most fundamental level.

Integrative and naturalistic philosophy of mind can both learn from and contribute to the contemporary cognitive sciences of dreaming. Two related phenomena concerning self-representation in dreams demonstrate the need to bring disparate fields together. In most dreams, the protagonist or dream self who experiences and actively participates in dream events is or represents the dreamer: but in an intriguing minority of cases, self-representation in dreams is displaced, disrupted, or even absent. Working from dream reports in established databanks, we examine two (...) key forms of polymorphism of self-representation: dreams in which I take an external visuospatial perspective on myself, and those in which I take someone else's perspective on events. In remembering my past experiences or imagining future or possible experiences when awake, I sometimes see myself from an external or 'observer' perspective. By relating the issue of perspective in dreams to established research traditions in the study of memory and imagery, and noting the flexibility of perspective in dreams, we identify new lines of enquiry. In other dreams, the dreamer does not appear to figure at all, and the first person perspective on dream events is occupied by someone else, some other person or character. We call these puzzling cases 'vicarious dreams' and assess some potential ways to make sense of them. Questions about self-representation and perspectives in dreams are intriguing in their own right and pose empirical and conceptual problems about the nature of self-representation with implications beyond the case of dreaming.

Aristotle is said to have held that any kind of actual infinity is impossible. I argue that he was a finitist (or "potentialist") about _magnitude_, but not about _plurality_. He did not deny that there are, or can be, infinitely many things in actuality. If this is right, then it has implications for Aristotle's views about the metaphysics of parts and points.

We present a rigorous way to evaluate the visual perception of correlation in scatterplots, based on classical psychophysical methods originally developed for simple properties such as brightness. Although scatterplots are graphically complex, the quantity they convey is relatively simple. As such, it may be possible to assess the perception of correlation in a similar way. Scatterplots were each of 5.0 extent, containing 100 points with a bivariate normal distribution. Means were 0.5 of the range of the points, and standard deviations (...) 0.2 of this range. Precision was determined via an adaptive algorithm to find the just noticeable differences (jnds) in correlation, i.e., the difference between two side-by-side scatterplots that could be discriminated 75% of the time. Accuracy was measured by direct estimation, using reference scatterplots with fixed upper and lower values, with a test scatterplot adjusted so that its correlation appeared to be halfway between these. This process was recursively applied to yield several further estimates. Results of the discrimination tests show jnd(r) = k (1/b – r), where r is the Pearson correlation, and parameters 0 < k, b < 1. Integration yields a subjective estimate of correlation g(r) = ln(1 – br) / ln(1– b). The values of b found via discrimination closely match those found via direct estimation. As such, it appears that the perception of correlation in a scatterplot is completely described by two related performance curves, specified by two easily-measured parameters. (shrink)

The intuitive view that memories are characterized by a feeling of pastness, perceptions by a feeling of presence, while imagination lacks either faces challenges from two sides. Some researchers complain that the “feeling of pastness” is either unclear, irrelevant or isn’t a real feature. Others point out that there are cases of memory without the feeling of pastness, perception without presence, and other cross-cutting cases. Here we argue that the feeling of pastness is indeed a real, useful feature, and although (...) this feeling does not define memory ontologically, it is a characteristic marker which helps us easily categorise a mental state first-personally. We outline several cognitive features that underlie this experience, including the feeling of past accessibility, ergonomic significance, immersion, objectivity and mental strength. Our account is distinctly phenomenal, rather than doxastic, although our web of beliefs may contribute to this experience. (shrink)

I propose a narrative fabrication thesis of dream reports, according to which dream reports are often not accurate representations of experiences that occur during sleep. I begin with an overview of anti-experience theses of Norman Malcolm and Daniel Dennett who reject the received view of dreams, that dreams are experiences we have during sleep which are reported upon waking. Although rejection of the first claim of the received view, that dreams are experiences that occur during sleep, is implausible, I evaluate (...) in more detail the second assumption of the received view, that dream reports are generally accurate. I then propose a “narrative fabrication” view of dreams as an alternative to the received view. Dream reports are often confabulated or fabricated because of poor memory, bizarre dream content, and cognitive deficits. It is well documented that narratives can be altered between initial rapid eye movement sleep awakenings and subsequent reports. I argue that we have reason to suspect that initial reports are prone to inaccuracy. Experiments demonstrate that subjects rationalize strange elements in narratives, leaving out supernatural or bizarre components when reporting waking memories of stories. Inaccuracies in dream reports are exacerbated by rapid memory loss and bizarre dream content. Waking memory is a process of reconstruction and blending of elements, but unlike waking memory, we cannot reality-test for dream memories. Dream experiences involve imaginative elements, and dream content cannot be verified with external evidence. Some dreams may involve wake-like higher cognitive functions, such as lucid dreams. Such dreams are more likely to elicit accurate reports than cognitively deficient dreams. However, dream reports are generally less accurate than waking reports. I then propose methods which could verify the narrative fabrication view, and argue that although the theory cannot be tested with current methods, new techniques and technologies may be able to do so in the future. -/- .

To what extent do I have a sense of agency over my thoughts while I dream? The sense of agency in dreams can alter in a variety of interesting ways distinct from normal, waking experience. In fact, dreams show many similarities to the experiences of individuals with schizophrenia. In this paper I analyze these alterations with a focus on distinguishing between reduced sense of agency and other cognitive features such as metacognition, confabulation and attention. I argue that some dream reports (...) demonstrate two interesting commonalities with schizophrenia: thought insertion (TI) and auditory hallucination (AH). This line of research has the potential to further our understanding of TI and AH in schizophrenia through the analysis of similar experience in a different conscious state. Through the analysis of dream reports, I found that although TI and AH both occur in dreams, TI is very rare. This is an interesting result since TI is common in patients with schizophrenia. I propose two speculative lines of explanation for the rarity of TI in dreams: first, the cognitive differences between the symptoms of schizophrenia and dreams, and second, the problem of dream reporting conditions. Dream reporting conditions are particularly important, as without controls, reports can be vague. Analysis of dream reports reveals that it is often unclear whether 'hearing voices' indicates sound phenomenology or thought phenomenology. I propose that dream reports could be disambiguated given the right experimental conditions and I suggest how this could be achieved in future experimental research. (shrink)

This paper takes as its point of departure recent research into the possibility that human beings can perceive single photons. In order to appreciate what quantum perception may entail, we first explore several of the leading interpretations of quantum mechanics, then consider an alternative view based on the ontological phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Next, the philosophical analysis is brought into sharper focus by employing a perceptual model, the Necker cube, augmented by the topology of the Klein bottle. (...) This paves the way for addressing in greater depth the paper’s central question: Just what would it take to observe the quantum reality of the photon? In formulating an answer, we examine the nature of scientific objectivity itself, along with the paradoxical properties of light. The conclusion reached is that quantum perception requires a new kind of observation, one in which the observer of the photon adopts a concretely self-reflexive observational posture that brings her into close ontological relationship with the observed. (shrink)

This paper seeks to extend my recent work on quantum perception (Rosen, 2021) to the phenomenon of quantum entanglement. In the first section, I summarize the earlier work, noting how the conventional approach to observing photons is rooted in an objectivist philosophy that serves as an obstacle to probing the underlying quantum reality. In the summary provided, I bring out the intimate relationship between observer and observed in the quantum world, and the need for a new, proprioceptive mode of (...) observation linked to phenomenological philosophy. The second part of the paper builds on the earlier effort by applying the proprioceptive observation of photons to the phenomenon of entanglement. The basic proposition is that proprioceptive observers of entangled photons may become entangled with each other. I propose an experiment that tests this hypothesis. In concluding, I explore the possibility that a quantum internet of proprioceptively engaged participants could create an ontologically entangled society. (shrink)

The first part of my hypothesis, then, is simple enough, and would be accepted in principle by most students of Plato: the dramatic structure of the dialogues is an essential part of their philosophical meaning. With respect to the poetic and mathematical aspects of philosophy, we may distinguish three general kinds of dialogue. For example, consider the Sophist and Statesman, where Socrates is virtually silent: the principal interlocutors are mathematicians and an Eleatic Stranger, a student of Parmenides, although one who (...) is not always loyal to his master's teaching of what might be called monadic homogeneity. In these dialogues, the mathematical character of philosophy is not merely emphasized but exaggerated, and any attempt to interpret them must take this fact into account. Otherwise, we shall not be able to understand why the Stranger seems to classify the general's art in the same species of the genus hunting as the louse catcher. The significance of this step, which does not stem from humanitarian considerations, but rather illustrates how the human becomes invisible from the mathematical viewpoint, contributes its share to the obscurity of these two dialogues. Second, there are dialogues like the Phaedrus and Symposium, in which the style, the interlocutors, and even the subject-matter seem to be largely poetic and rhetorical. Here, the overwhelming impression is of enthusiasm, divine madness, and intoxication in speech and deed. Finally, there are dialogues like the Philebus and Republic, in which it is not so easy to say whether poetry or mathematics predominates, if indeed either may be said to do so. (shrink)

On Zeno Beach there are infinitely many grains of sand, each half the size of the last. Supposing Aristotle denied the possibility of Zeno Beach, did he have a good argument for the denial? Three arguments, each of ancient origin, are examined: the beach would be infinitely large; the beach would be impossible to walk across; the beach would contain a part equal to the whole, whereas parts must be lesser. It is attempted to show that none of these arguments (...) was Aristotle’s. Indeed, perhaps Aristotle’s finitism applied to magnitude only, not plurality. (shrink)

I consider the question of the possibility of the coexistence of neighborly love (love for strangers) and preferential love (love for persons because of or despite their attributes). This question has long perplexed interpreters of Kierkegaard. I make a threefold intervention into this interpretive debate. First, I aim to show that we shouldn’t privilege preferential love over neighborly love. Second, I reformulate preferential and neighborly love on a ‘topological’ model, so as to get a better grip on them. And third, (...) I argue that preferential love can coexist with neighborly love insofar as the latter is granted primacy over the former. (shrink)

In the author’s previous contribution to this journal (Rosen 2015), a phenomenological string theory was proposed based on qualitative topology and hypercomplex numbers. The current paper takes this further by delving into the ancient Chinese origin of phenomenological string theory. First, we discover a connection between the Klein bottle, which is crucial to the theory, and the Ho-t’u, a Chinese number archetype central to Taoist cosmology. The two structures are seen to mirror each other in expressing the psychophysical (phenomenological) (...) action pattern at the heart of microphysics. But tackling the question of quantum gravity requires that a whole family of topological dimensions be brought into play. What we find in engaging with these structures is a closely related family of Taoist forebears that, in concert with their successors, provide a blueprint for cosmic evolution. Whereas conventional string theory accounts for the generation of nature’s fundamental forces via a notion of symmetry breaking that is essentially static and thus unable to explain cosmogony successfully, phenomenological/Taoist string theory entails the dialectical interplay of symmetry and asymmetry inherent in the principle of synsymmetry. This dynamic concept of cosmic change is elaborated on in the three concluding sections of the paper. Here, a detailed analysis of cosmogony is offered, first in terms of the theory of dimensional development and its Taoist (yin-yang) counterpart, then in terms of the evolution of the elemental force particles through cycles of expansion and contraction in a spiraling universe. The paper closes by considering the role of the analyst per se in the further evolution of the cosmos. (shrink)

Aristotle offers several arguments in Physics viii.8 for his thesis that, when something moves back and forth, it does not undergo a single motion. These arguments occur against the background of a sophisticated theory, expounded in Physics v—vi, of the basic structure of motions and of other continuous entities such as times and magnitudes. The arguments in Physics viii.8 stand in a complex relation to that theory. On the one hand, Aristotle evidently relies on the theory in a number of (...) crucial steps. Yet in other steps he seems to contradict or misapply the theory. This situation offers the occasion to examine Aristotle’s views about some fundamentals in the metaphysics of motion, while also raising questions about the unity of the text which has come down to us as the Physics.

Quakers express their faith by refraining from war, often actively opposing it. In modern Quakerism, this is known as the ‘Peace Testimony’. This commonly has a negative and positive construal: it is seen as a testimony against war, and as a testimony to the possibility and goodness of peaceful lives. This paper offers an account of how these aspects of the Peace Testimony are unified in and grounded on a corporate experience of being led by God into a way of (...) life that renders war unthinkable. My goal is to make sense of Friends’ activism in light of their religious experience and to introduce some ideas from Quaker practical theology to philosophers and theologians more generally. I begin by considering the role of what Rachel Muers calls ‘negative testimony’ in Quaker peace work, arguing that we risk misunderstanding this work if we do not see the unity of the Peace Testimony’s negativity and Friends’ positive peace-making endeavors. I then turn to the Testimony’s ground, which I claim can be nothing other than an experience of direct revelation. I conclude by arguing that prominent objections to pacifism, such as Elizabeth Anscombe’s, hold little weight against the Peace Testimony. (shrink)

Other people figure in our experience of the world; they strike us as unique and gen- uinely other. This paper explores whether a Husserlian account of empathy as the way in which we constitute an intersubjective world can account for the uniqueness and otherness of other people in our experience. I contend that it can’t. I begin by explicating Husserl’s theory of empathy, paying particular attention to the reduction to a purely egoic sphere and the steps that ostensibly permit a (...) subject to re-inhabit a world of others from out of this sphere. In querying Husserl’s theory, I consider a series of problems, raised by Zhida Luo, concerning the apparent centrality of bod- ily similarity in empathy. I sketch Luo’s solution, which involves a shift to tactile similarity. While it makes for a better theory of empathy, this solution isn’t sufficient to make room for the givenness of another person not originally predicated on simi- larity. To clarify what’s at issue here, I turn to the Husserlian pictures of empathy presented by Heinz Kohut and Edith Stein. I conclude with a remark about what might be required, given the inability of Husserlian empathy to make room for the experience of others as singular and other, for a picture of our phenomenal life to have a shape that accounts for the coexistence of empathy to others who are like oneself and hospitality to others as genuine others.

Gideon Rosen has recently sketched an argument which aims to establish that the notion of metaphysical modality is systematically ambiguous. His argument contains a crucial sub-argument which has been used to argue for Metaphysical Contingentism, the view that some claims of fundamental metaphysics are metaphysically contingent rather than necessary. In this paper, Rosen’s argument is explicated in detail and it is argued that the most straight-forward reconstruction fails to support its intended conclusion. Two possible ways to save (...) the argument are rebutted and it is furthermore argued that the crucial sub-argument only supports a rather particular variant of Metaphysical Contingentism. (shrink)

I propose a distinction between two concepts: affliction and atrocity. I argue that an ethical position with respect to history’s horrors can be understood as a practice of refusing to permit affliction to be seen as atrocity. This is a practice of resisting the urge to quantify or qualify affliction in subjecting it to a count of bodies, which would be taken to totalize all the suffering in a given situation. We should, I contend, resist thinking that affliction qualified as (...) atrocity, subject to a count of bodies or the like, captures affliction itself. I then discuss several instances of the qualification of affliction as atrocity, including the Sétif and Guelma massacre, the crucifixion of Christ, and the biblical story of the bondage of the Israelites in Egypt. I conclude by making a case that it’s ethically imperative that we recollect the self’s abnegation to those who aren’t counted, those who can’t be counted because they are afflicted without atrocity.

​This article considers the place of moral concerns about hospitality and welcoming in the politics of the Ejército Zapatista de Liberación Nacional (Zapatista Army of National Liberation, or EZLN). I argue that the EZLN’s political model exemplifies some of what I think to be characteristic of the ideal relationship between politics, concerned with sameness and collective identities, and ethics, concerned with hospitality to those who are genuinely different.

This essay discusses the role that welcoming and hospitality play in communal and political life, and the role they ought to play. It also considers the relationship between ethics in its concern for hospitality to those who are different and politics in its concern for collective understanding and the solidification of group identities.

Recursion or self-reference is a key feature of contemporary research and writing in semiotics. The paper begins by focusing on the role of recursion in poststructuralism. It is suggested that much of what passes for recursion in this field is in fact not recursive all the way down. After the paradoxical meaning of radical recursion is adumbrated, topology is employed to provide some examples. The properties of the Moebius strip prove helpful in bringing out the dialectical nature of radical recursion. (...) The Moebius is employed to explore the recursive interplay of terms that are classically regarded as binary opposites: identity and difference, object and subject, continuity and discontinuity, etc. To realize radical recursion in an even more concrete manner, a higher-dimensional counterpart of the Moebius strip is utilized, namely, the Klein bottle. The presentation concludes by enlisting phenomenological philosopher Maurice Merleau-Ponty’s concept of depth to interpret the Klein bottle’s extra dimension. (shrink)

O desempenho das empresas tem sido estudado sob diferentes perspectivas teóricas, que, em geral a utilizam indicadores econômico-financeiros. Essa abordagem sofre constantes críticas por não contemplar aspectos estratégicos, que podem fornecer informações acerca de vantagem competitiva obtida pela empresa. Fatores macroeconômicos também tendem a impactar de maneira indireta os diferentes setores. Além disso, os setores sofrem esses impactos macroeconômicos conforme o nível de exposição deste às oscilações macroeconômicas. Assim este trabalho buscou analisar como as dimensões de desempenho se relacionam com (...) retorno, para cada setor da bolsa de valores. Para a análise, utilizou-se a modelagem de equações estruturais a partir do software Smart-PLS. Foram utilizados dados do Economática para 82 empresas listadas em 6 setores da B3 no período entre 2011 e 2018. Os resultados indicam que diferentes indicadores compõe os construtos para cada setor analisado, indicando que o retorno tem associações diferentes em cada setor. O construto econômico-financeiro apresenta uma relação positiva na explicação dos retornos para os diferentes setores. Já o construto estratégico relacionou-se positivamente apenas no setor de Materiais Básicos. A dimensão macroeconômica apresentou resultados que evidenciam uma relação negativa com os retornos no período analisado. Assim pode-se apontar que o retorno de cada setor é explicado por diferentes informações, sugerindo que o investidor deve observar critérios específicos de cada setor. Os indicadores macroeconômicos foram similares para os setores analisados, contudo o impacto significativo não pode ser verificado para todos os setores, indicando que existem níveis de exposição diferentes para os setores. Ainda, foram evidenciados tanto efeitos diretos quanto indiretos dos indicadores macroeconômicos sobre o retorno. (shrink)

Malink’s interpretation is designed to validate Aristotle’s claims of validity and invalidity of syllogistic-style arguments, as well as his conversion claims. The remaining sorts of claims in Aristotle's text are allowed to fall out as they may. Thus, not all of Aristotle’s examples turn out correct: on some occasions, Aristotle claims that a given pair of terms yields a true (false) sentence of a given type although, under Malink’s interpretation, the sentence in question is false (true). Similarly, some of Aristotle’s (...) claims of invalidity of nonsyllogistic-style arguments come out false. For example, under Malink’s interpretation, ‘A applies to all B’ and ‘B necessarily applies to all C’ entail ‘A necessarily applies to some B’, contrary to what Aristotle says. (shrink)

The Brock-Rosen problem has been one of the most thoroughly discussed objections to the modal fictionalism bruited in Gideon Rosen’s ‘Modal Fictionalism’. But there is a more fundamental problem with modal fictionalism, at least as it is normally explained: the position does not resolve the tension that motivated it. I argue that if we pay attention to a neglected aspect of modal fictionalism, we will see how to resolve this tension—and we will also find a persuasive reply (...) to the Brock-Rosen objection. Finally, I discuss an alternative reading of Rosen, and argue that this position is also able to fend off the Brock-Rosen objection. (shrink)

Hermeneutic fictionalism about mathematics maintains that mathematics is not committed to the existence of abstract objects such as numbers. Mathematical sentences are true, but they should not be construed literally. Numbers are just fictions in terms of which we can conveniently describe things which exist. The paper defends Stephen Yablo’s hermeneutic fictionalism against an objection proposed by John Burgess and Gideon Rosen. The objection, directed against all forms of nominalism, goes as follows. Nominalism can take either a hermeneutic (...) form and claim that mathematics, when rightly understood, is not committed to the existence of abstract objects, or a revolutionary form and claim that mathematics is to be understood literally but is false. The hermeneutic version is said to be untenable because there is no philosophically unbiased linguistic argument to show that mathematics should not be understood literally. Against this I argue that it is wrong to demand that hermeneutic fictionalism should be established solely on the basis of linguistic evidence. In addition, there are reasons to think that hermeneutic fictionalism cannot even be defeated by linguistic arguments alone. (shrink)

In this paper, I describe and motivate a new species of mathematical structuralism, which I call Instrumental Nominalism about Set-Theoretic Structuralism. As the name suggests, this approach takes standard Set-Theoretic Structuralism of the sort championed by Bourbaki and removes its ontological commitments by taking an instrumental nominalist approach to that ontology of the sort described by Joseph Melia and Gideon Rosen. I argue that this avoids all of the problems that plague other versions of structuralism.

Recently, a number of authors have suggested that the epistemic condition on moral responsibility makes blameworthiness much less common than we ordinarily suppose, and much harder to identify. This paper argues that such epistemically based responsibility skepticism is mistaken. Section 2 sketches a general account of moral responsibility, building on the Strawsonian idea that blame and credit relates to the agent’s quality of will. Section 3 explains how this account deals with central cases that motivate epistemic skepticism and how it (...) avoids some objections to quality of will accounts recently raised by Gideon Rosen. But an intuitive worry brought out by these objections remains. Section 4 spells out this remaining worry and argues that, like traditional metaphysical responsibility skepticism, it has its source in a non-standard explanatory perspective on action, suggesting that strategies for explaining away the intuitive pull of traditional skepticism are applicable in this case too.

According to truthmaker theory, particular truths are true in virtue of the existence of particular entities. Truthmaker maximalism holds that this is so for all truths. Negative existential and other ‘negative’ truths threaten the position. Despite this, maximalism is an appealing thesis for truthmaker theorists. This motivates interest in parsimonious maximalist theories, which do not posit extra entities for truthmaker duty. Such theories have been offered by David Lewis and Gideon Rosen, Ross Cameron, and Jonathan Schaffer. But these (...) theories cannot be sustained, I’ll argue, and hence maximalism comes with a serious ontological cost. Neither Armstrong’s invocation of totality facts nor the Martin-Kukso line on absences can meet this cost satisfactorily. I’ll claim that negative facts are the best (and perhaps only) way out of the problem for the truthmaker maximalist. (shrink)

Platonism in the philosophy of mathematics is the doctrine that there are mathematical objects such as numbers. John Burgess and Gideon Rosen have argued that that there is no good epistemological argument against platonism. They propose a dilemma, claiming that epistemological arguments against platonism either rely on a dubious epistemology, or resemble a dubious sceptical argument concerning perceptual knowledge. Against Burgess and Rosen, I show that an epistemological anti- platonist argument proposed by Hartry Field avoids both horns (...) of their dilemma. (shrink)

In this paper I discuss various hard cases that an account of moral ignorance should be able to deal with: ancient slave holders, Susan Wolf’s JoJo, psychopaths such as Robert Harris, and finally, moral outliers. All these agents are ignorant, but it is not at all clear that they are blameless on account of their ignorance. I argue that the discussion of this issue in recent literature has missed the complexities of these cases by focusing on the question of epistemic (...) fault. It is not clear that all blameworthy morally ignorant agents have committed an epistemic fault. There are other important issues that pull us in various directions: moral capacity, bad will, and formative circumstances. I argue that bad will is what is crucial, and moral ignorance itself can be a form of bad will. I argue that we should distinguish between two sorts of bad will, and correspondingly, two sorts of blameworthiness. Ordinary blameworthiness, requires moral knowledge, and is based on akratic action. The other kind of blameworthiness, objective blameworthiness, applies when the agent is morally ignorant, and when this indicates bad will. Objective blameworthiness can be undermined by unfortunate formative circumstances. (shrink)

Many philosophers of mathematics are attracted by nominalism – the doctrine that there are no sets, numbers, functions, or other mathematical objects. John Burgess and Gideon Rosen have put forward an intriguing argument against nominalism, based on the thought that philosophy cannot overrule internal mathematical and scientific standards of acceptability. I argue that Burgess and Rosen’s argument fails because it relies on a mistaken view of what the standards of mathematics require.

As the debate between realists and empiricists in the philosophy of science drags on, one point of consensus has emerged: no one wants to be a manifestationalist. The manifestationalist is a kind of radical empiricist who argues that science provides theories that aim neither at a true picture of the entire world, nor even an empirically adequate picture that captures the world in all its observable respects. For manifestationalists, science aims only at providing theories that are true to the observed (...) aspects of reality. If the guiding idea of empiricism is that experience, and experience alone, provides us with knowledge about the world, then manifestationalism is an exceptionally strict empiricist perspective on science. Manifestationalism has primarily served within a reductio: certain empiricist views and arguments, when taken to their logical conclusion, lead to manifestationalism and so cannot be correct. The reductio works only because manifestationalism is widely agreed to be a non-starter. However, this consensus against manifestationalism is based on a single argument. We contest this assessment of manifestationalism and show that the primary argument against manifestationalism fails to hit its target. We do not intend to offer a manifesto for manifestationalism. Rather, we aim to vindicate it from a false accusation. Manifestationalism may not be the correct view of science, but the objections levied against it so far can be met. (shrink)

In this paper I present two new arguments against the possibility of an omniscient being. My new arguments invoke considerations of cardinality and resemble several arguments originally presented by Patrick Grim. Like Grim, I give reasons to believe that there must be more objects in the universe than there are beliefs. However, my arguments will rely on certain mereological claims, namely that Classical Extensional Mereology is necessarily true of the part-whole relation. My first argument is an instance of a problem (...) first noted by Gideon Rosen and requires an additional assumption about the mereological structure of certain beliefs. That assumption is that an omniscient being’s beliefs are mereological simples. However, this assumption is dropped when I present my second argument. Thus, I hope to show that if Classical Extensional Mereology is true of the part-whole relation, there cannot be an omniscient being. (shrink)

I argue against the claim that morally ignorant wrongdoers are open to blame only if they are culpable for their ignorance, and I argue against a version of skepticism about moral responsibility that depends on this claim being true. On the view I defend, the attitudes involved in blame are typically responses to the features of an action that make it objectionable or unjustifiable from the perspective of the one who issues the blame. One important way that an action can (...) appear objectionable to us is that it expresses a judgment with which we disagree about the significance of the interests of those affected by the action. A morally ignorant wrongdoer’s actions may express such judgments even if it is not her fault that she is unaware of the moral status of her behavior, and even if it would be unreasonable to expect her to be aware of its status.
