Translation and commentary on the only surviving sustained work on Plato's Phaedrus from antiquity.

This commentary records, through notes taken by Hermias, Syrianus' seminar on Plato's Phaedrus, one of the world's most influential celebrations of erotic beauty and love. It is the only Neoplatonic commentary on Plato's Phaedrus to have survived in its entirety. Further interest comes from the recorded interventions by Syrianus' pupils - including those by Proclus, his eventual successor as head of the Athenian school, who went on to teach Hermias' father, Ammonius. The second of two volumes of Hermias' commentary, the (...) chapters translated here begin with a discussion of how the discarnate soul is visualised as a winged chariot team whose charioteer may gain some glimpse of beauty itself, which can explain subsequent erotic longing. This volume provides a translation is accompanied by explanatory notes, an introduction detailing the significance and context of the treatise and a scholarly apparatus including multiple indexes, glossaries and a bibliography.

This paper elaborates on relationalism about space and time as motivated by a minimalist ontology of the physical world: there are only matter points that are individuated by the distance relations among them, with these relations changing. We assess two strategies to combine this ontology with physics, using classical mechanics as example: the Humean strategy adopts the standard, non-relationalist physical theories as they stand and interprets their formal apparatus as the means of bookkeeping of the change of the distance relations (...) instead of committing us to additional elements of the ontology. The alternative theory strategy seeks to combine the relationalist ontology with a relationalist physical theory that reproduces the predictions of the standard theory in the domain where these are empirically tested. We show that, as things stand, this strategy cannot be accomplished without compromising a minimalist relationalist ontology. (shrink)

Epistemic Contextualism is the view that “knows that” is semantically context-sensitive and that properly accommodating this fact into our philosophical theory promises to solve various puzzles concerning knowledge. Yet Epistemic Contextualism faces a big—some would say fatal—problem: The Semantic Error Problem. In its prominent form, this runs thus: speakers just don’t seem to recognise that “knows that” is context-sensitive; so, if “knows that” really is context-sensitive then such speakers are systematically in error about what is said by, or how to (...) evaluate, ordinary uses of “S knows that p”; but since it's wildly implausible that ordinary speakers should exhibit such systematic error, the expression “knows that” isn't context-sensitive. We are interested in whether, and in what ways, there is such semantic error; if there is such error, how it arises and is made manifest; and, again, if there is such error to what extent it is a problem for Epistemic Contextualism. The upshot is that some forms of The Semantic Error Problem turn out to be largely unproblematic. Those that remain troublesome have analogue error problems for various competitor conceptions of knowledge. So, if error is any sort of problem, then there is a problem for every extant competitor view. (shrink)

This work addresses the autonomous organization of biological systems. It does so by considering the boundaries of biological systems, from individual cells to Home sapiens, in terms of the presence of Markov blankets under the active inference scheme—a corollary of the free energy principle. A Markov blanket defines the boundaries of a system in a statistical sense. Here we consider how a collective of Markov blankets can self-assemble into a global system that itself has a Markov blanket; thereby providing an (...) illustration of how autonomous systems can be understood as having layers of nested and self-sustaining boundaries. This allows us to show that: (i) any living system is a Markov blanketed system and (ii) the boundaries of such systems need not be co-extensive with the biophysical boundaries of a living organism. In other words, autonomous systems are hierarchically composed of Markov blankets of Markov blankets—all the way down to individual cells, all the way up to you and me, and all the way out to include elements of the local environment.

There are at least twelve major virtues of good theories: evidential accuracy, causal adequacy, explanatory depth, internal consistency, internal coherence, universal coherence, beauty, simplicity, unification, durability, fruitfulness, and applicability. These virtues are best classified into four classes: evidential, coherential, aesthetic, and diachronic. Each virtue class contains at least three virtues that sequentially follow a repeating pattern of progressive disclosure and expansion. Systematizing the theoretical virtues in this manner clarifies each virtue and suggests how they might have a coordinated and cumulative (...) role in theory formation and evaluation across the disciplines—with allowance for discipline specific modification. An informal and flexible logic of theory choice is in the making here. Evidential accuracy, according to my systematization, is not a largely isolated trait of good theories, as some have made it out to be. Rather, it bears multifaceted relationships, constituting significant epistemic entanglements, with other theoretical virtues. (shrink)

This paper defends a theory of hope according to which hopes are composed of a desire and a belief that the object of the desire is possible. Although belief plus desire theories of hope are now widely rejected, this is due to important oversights. One is a failure to recognize the relation that hope-constituting desires and beliefs must stand in to constitute a hope. A second is an oversimplification of the explanatory power of hope-constituting desires. The final portion of the (...) paper uses an enhanced understanding of the psychology of hope to make progress on normative questions about hoping well. (shrink)

According to a historically popular view, emotions are normative experiences that ground moral knowledge much as perceptual experiences ground empirical knowledge. Given the analogy it draws between emotion and perception, sentimental perceptualism constitutes a promising, naturalist-friendly alternative to classical rationalist accounts of moral knowledge. In this paper, we consider an important but underappreciated objection to the view, namely that in contrast with perception, emotions depend for their occurrence on prior representational states, with the result that emotions cannot give perceptual-like access (...) to normative properties. We argue that underlying this objection are several specific problems, rooted in the different types of mental states to which emotions may respond, that the sentimental perceptualist must tackle for her view to be successful. We argue, moreover, that the problems can be answered by filling out the theory with several independently motivated yet highly controversial commitments, which we carefully catalogue. The plausibility of sentimental perceptualism, as a result, hinges on further claims sentimental perceptualists should not ignore. (shrink)

This paper considers questions about continuity and discontinuity between life and mind. It begins by examining such questions from the perspective of the free energy principle (FEP). The FEP is becoming increasingly influential in neuroscience and cognitive science. It says that organisms act to maintain themselves in their expected biological and cognitive states, and that they can do so only by minimizing their free energy given that the long-term average of free energy is entropy. The paper then argues that there (...) is no singular interpretation of the FEP for thinking about the relation between life and mind. Some FEP formulations express what we call an independence view of life and mind. One independence view is a cognitivist view of the FEP. It turns on information processing with semantic content, thus restricting the range of systems capable of exhibiting mentality. Other independence views exemplify what we call an overly generous non-cognitivist view of the FEP, and these appear to go in the opposite direction. That is, they imply that mentality is nearly everywhere. The paper proceeds to argue that non-cognitivist FEP, and its implications for thinking about the relation between life and mind, can be usefully constrained by key ideas in recent enactive approaches to cognitive science. We conclude that the most compelling account of the relationship between life and mind treats them as strongly continuous, and that this continuity is based on particular concepts of life (autopoiesis and adaptivity) and mind (basic and non-semantic).

The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that (...) one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go on to discuss recent evidence indicating that immersion in VR can have psychological effects that last after leaving the virtual environment. In the second part of the article, we turn to the risks and recommendations. We begin, in Section “The Research Ethics of VR,” with the research ethics of VR, covering six main topics: the limits of experimental environments, informed consent, clinical risks, dual-use, online research, and a general point about the limitations of a code of conduct for research. Then, in Section “Risks for Individuals and Society,” we turn to the risks of VR for the general public, covering four main topics: long-term immersion, neglect of the social and physical environment, risky content, and privacy. We offer concrete recommendations for each of these 10 topics, summarized in Table 1. (shrink)

This paper asks whether there is a moral virtue of hope, and if so, what it is. The enterprise is motivated by a historical asymmetry, namely that while Christian thinkers have long classed hope as a theological virtue, it has not traditionally been classed as a moral one. But this is puzzling, for hoping well is not confined to the sphere of religion; and consequently we might expect that if the theological virtue is structurally sound, there will be a secular, (...) moral analogue. This paper proposes that there is such an analogue, and that it is closely linked to the everyday notion of “having your priorities straight,” a phenomenon which is naturally understood in terms of the attitude of hope. It turns out that the priorities model provides an abstract way of characterizing a central but underexplored virtue, one which can be developed in secular or theological ways. (shrink)

More and more researchers argue that online technologies manipulate human users and, therefore, undermine their autonomy. We call this the MAL view on online technology because it argues from Manipulation to Autonomy-Loss. MAL enjoys public visibility and will shape the academic discussion to come. This view of online technology, however, fails conceptually. MAL presupposes that manipulation equals autonomy loss, and that autonomy is the absence of manipulation. That is mistaken. In short, an individual can be manipulated while being fully personally (...) autonomous. Internet policy researchers should be aware of this point to avoid looking in the wrong place in future research on manipulative and harmful online technology. (shrink)

Imagination is necessary for scientific practice, yet there are no in vivo sociological studies on the ways that imagination is taught, thought of, or evaluated by scientists. This article begins to remedy this by presenting the results of a qualitative study performed on two systems biology laboratories. I found that the more advanced a participant was in their scientific career, the more they valued imagination. Further, positive attitudes toward imagination were primarily due to the perceived role of imagination in problem-solving. (...) But not all problem-solving episodes involved clear appeals to imagination, only maximally specific problems did. This pattern is explained by the presence of an implicit norm governing imagination use in the two labs: only use imagination on maximally specific problems, and only when all other available methods have failed. This norm was confirmed by the participants, and I argue that it has epistemological reasons in its favour. I also found that its strength varies inversely with career stage, such that more advanced scientists do (and should) occasionally bring their imaginations to bear on more general problems. A story about scientific pedagogy explains the trend away from (and back to) imagination over the course of a scientific career. Finally, some positive recommendations are given for a more imagination-friendly scientific pedagogy. (shrink)

Social media use is soaring globally. Existing research of its ethical implications predominantly focuses on the relationships amongst human users online, and their effects. The nature of the software-to-human relationship and its impact on digital well-being, however, has not been sufficiently addressed yet. This paper aims to close the gap. I argue that some intelligent software agents, such as newsfeed curator algorithms in social media, manipulate human users because they do not intend their means of influence to reveal the user’s (...) reasons. I support this claim by defending a novel account of manipulation and by showing that some intelligent software agents are manipulative in this sense. Apart from revealing a priori reason for thinking that some intelligent software agents are manipulative, the paper offers a framework for further empirical investigation of manipulation online.

This is the introduction to the Routledge Companion to Thought Experiments.

This article articulates a framework for normatively assessing influence operations, undertaken by national security institutions. Section I categorizes the vast field of possible types of influence operations according to the communication’s content, its attribution, the rights of the target audience, the communication’s purpose, and its secondary effects. Section II populates these categories with historical examples and section III evaluates these cases with a moral framework. I argue that deceptive or manipulative communications directed at non-liable audiences are presumptively immoral and illegitimate (...) for liberal states, as are deceptive operations aimed at an unjust end, or even operations aimed at a just end where secondary effects are forecast to be disproportionate to the proximate end.

Religious fictionalism is the theory that it is morally and intellectually legitimate to affirm religious sentences and to engage in public and private religious practices, without believing the content of religious claims. This article discusses the main features of fictionalism, contrasts hermeneutic, and revolutionary kinds of fictionalism and explores possible historical and recent examples of religious fictionalism. Such examples are found in recent theories of faith, pragmatic approaches to religion, and mystical traditions in religious theology.

Basic Emotion Theory, or BET, has dominated the affective sciences for decades (Ekman, 1972, 1992, 1999; Ekman and Davidson, 1994; Griffiths, 2013; Scarantino and Griffiths, 2011). It has been highly influential, driving a number of empirical lines of research (e.g., in the context of facial expression detection, neuroimaging studies and evolutionary psychology). Nevertheless, BET has been criticized by philosophers, leading to calls for it to be jettisoned entirely (Colombetti, 2014; Hufendiek, 2016). This paper defuses those criticisms. In addition, it shows (...) that we have good reason to retain BET. Finally, it reviews and puts to rest worries that BET’s commitment to affect programs renders it outmoded. We propose that, with minor adjustments, BET can avoid such criticisms when conceived under a radically enactive account of emotions. Thus, rather than leaving BET behind, we show how its basic ideas can be revised, refashioned and preserved. Hence, we conclude, our new BET is still a good bet. (shrink)

This paper explores the epistemological significance of the view that we can literally see, hear, and touch evaluative properties (the high-level theory of value perception). My central contention is that, from the perspective of epistemology, the question of whether there are such high-level experiences doesn’t matter. Insofar as there are such experiences, they most plausibly emerged through the right kind of interaction with evaluative capacities that are not literally perceptual (e.g., of the sort involved in imaginative evaluative reflection). But even (...) if these other evaluative capacities turn out not to alter the content of perceptual experience, they would still be sufficient to do all of the justificatory work that high-level experiences are meant to do. I close by observing that it may matter a great deal whether a certain other picture of value perception is true. This alternative picture has it that desires and/or emotions are perceptual-like experiences of value. (shrink)

If there is something (P) that every possible agent is committed to value, and certain actions or attitudes either enhance or diminish P, then normative claims about a range of intentional actions can be objectively and non-trivially evaluated. I argue that the degree of existence as an agent depends on the consistency of reflexive-relating with other individuals of the agent-kind: the ontological thesis. I then show that in intending to act on a reason, every agent is rationally committed to value (...) ‘above all else’ being an agent, what consists in exercising the capacity to act and having the freedom to discriminate between more or less valuable actions: the transcendental thesis. Since the degree of possession of this personal but non-contingent good depends on relating to other agents in a special way, certain actions and attitudes may be objectively right or wrong for all agents.

There is a loud and persistent drum beat of support for schools, for citizenship, for diversity and inclusion, and increasingly for labor market readiness with very little critical attention to the assumptions underlying these agendas, let alone to their many internal contradictions. Accordingly, in this book I examine the philosophical, motivational, and practical challenges of education theory, policy, and practice in the twenty-first century. As I proceed, I do not neglect the historical, comparative international context so essential to better understanding (...) where we are, as well as what is attainable in terms of educational justice. I argue that we must constructively critique some of our most cherished beliefs about education if we are to save the hope of real justice from the rhetoric of imagined justice. (shrink)

Evaluative claims and assumptions are ubiquitous in positive psychology. Some will deny this. But such disavowals are belied by the literature. Some will consider the presence of evaluative claims a problem and hope to root them out. But this is a mistake. If positive psychology is to live up to its raison d’être – to be the scientific study of the psychological components of human flourishing or well-being – it must make evaluative claims. Well-being consists in those things that are (...) good for us, that make life go well. Thus, one cannot investigate this topic without making claims about what is good for people and what they have reason to do. It’s time, therefore, to embrace the fact that positive psychology is value-laden. Doing so would benefit the field by allowing for more rigorous theorizing, and – perhaps counterintuitively – increasing the field’s objectivity. (shrink)

Solidarity is a widespread but under-explored phenomenon. In this paper, I give a philosophical account of solidarity, answering three salient questions: What motivates acts of solidarity? What unifies different acts into tokens of a single type of act, one of solidarity? And what values do acts of solidarity exhibit? The answer to all three, I argue, involves a certain way of relating to others: identifying with them on the basis of shared features, and identifying with the larger group that one (...) and the others both belong to.

Moral philosophy continues to be enriched by an ongoing empirical turn,mainly through contributions from neuroscience, biology, and psychology. Thusfar, cultural anthropology has largely been missing. A recent and rapidly growing‘ethical turn’ within cultural anthropologynow explicitly and systematically studiesmorality. This research report aims to introduce to an audience in moral philosophyseveral notable works within the ethical turn. It does so by critically discussing theethical turn’s contributions to four topics: the definition of morality, the nature ofmoral change and progress, the truth of (...) moral relativism, and attempts to debunkmorality. The ethical turn uncovers a richer picture of moral phenomena on theintersubjective level, one akin to a virtue theoretic focus on moral character, withstriking similarities of moral phenomena across cultures. Perennial debates are notsettled but the ethical turn strengthens moral philosophy’s empirical turn and itrewards serious attention from philosophers. (shrink)

According to phenomenalism, physical things are a certain kind of possibility for experience. This paper clarifies the phenomenalist position and addresses some main objections to it, with the aim of showing that phenomenalism is a live option that merits a place alongside dualism and materialism in contemporary metaphysical debate.

A recent surge of work on prediction-driven processing models--based on Bayesian inference and representation-heavy models--suggests that the material basis of conscious experience is inferentially secluded and neurocentrically brain bound. This paper develops an alternative account based on the free energy principle. It is argued that the free energy principle provides the right basic tools for understanding the anticipatory dynamics of the brain within a larger brain-body-environment dynamic, viewing the material basis of some conscious experiences as extensive--relational and thoroughly world-involving.

When philosophers discuss the possibility of machines making scientific discoveries, they typically focus on discoveries in physics, biology, chemistry and mathematics. Observing the rapid increase of computer-use in science, however, it becomes natural to ask whether there are any scientific domains out of reach for machine discovery. For example, could machines also make discoveries in qualitative social science? Is there something about humans that makes us uniquely suited to studying humans? Is there something about machines that would bar them from (...) such activity? A close look at the methodology of interpretive social science reveals several abilities necessary to make a social scientific discovery, and one capacity necessary to possess any of them is imagination. For machines to make discoveries in social science, therefore, they must possess imagination algorithms. (shrink)

This paper shows how the availability heuristic can be used to justify inference to the best explanation in such a way that van Fraassen's infamous "best of a bad lot" objection can be adroitly avoided. With this end in mind, a dynamic and contextual version of the erotetic model of explanation sufficient to ground this response is presented and defended.

The Growing Block Theory of time says that the metaphysical openness of the future should be understood in terms of there not being any future objects or events. But in a series of works, Ross Cameron, Elizabeth Barnes, and Robbie Williams have developed a competing view that understands metaphysical openness in terms of it being indeterminate whether there exist future objects or events. I argue that the three reasons they give for preferring their account are not compelling. And since the (...) notion of “indeterminate existence” suffers conceptual problems, the Growing Block is the preferable view. (shrink)

This paper defends Flatland—the view that there exist neither determination nor dependence relations, and that everything is therefore fundamental—from the objection from explanatory inefficacy. According to that objection, Flatland is unattractive because it is unable to explain either the appearance as of there being determination relations, or the appearance as of there being dependence relations. We show how the Flatlander can meet the first challenge by offering four strategies—reducing, eliminating, untangling and omnizing—which, jointly, explain the appearance as of there being (...) determination relations where no such relations obtain. Since, plausibly, dependence relations just are asymmetric determination relations, we argue that once we come mistakenly to believe that there exist determination relations, the existence of other asymmetries (conceptual and temporal) explains why it appears that there are dependence relations.

This essay has two aims. The first is to correct an increasingly popular way of misunderstanding Belot's Orgulity Argument. The Orgulity Argument charges Bayesianism with defect as a normative epistemology. For concreteness, our argument focuses on Cisewski et al.'s recent rejoinder to Belot. The conditions that underwrite their version of the argument are too strong and Belot does not endorse them on our reading. A more compelling version of the Orgulity Argument than Cisewski et al. present is available, however---a point (...) that we make by drawing an analogy with de Finetti's argument against mandating countable additivity. Having presented the best version of the Orgulity Argument, our second aim is to develop a reply to it. We extend Elga's idea of appealing to finitely additive probability to show that the challenge posed by the Orgulity Argument can be met. (shrink)

There has been a growing charge that perdurantism—with its bloated ontology of very person-like objects that coincide persons—implies the repugnant conclusion that we are morally obliged to be feckless. I argue that this charge critically overlooks the epistemic situation—what I call the ‘veil of ignorance’—that perdurantists find themselves in. Though the veil of ignorance still requires an alteration of our commonsense understanding of the demands on action, I argue for two conclusions. The first is that the alteration that is required (...) isn’t a moral one, but rather an alteration of prudential reasoning. Second, and more importantly, this alteration isn’t necessarily a repugnant one. In fact, given that it prudentially pushes one towards greater impartiality, it may be seen as a point in favor of perdurantism. (shrink)

This paper argues that Epictetus’ ethics involves three features which are also present in Aristotle’s discussion of akrasia in the Nicomachean Ethics: 1) A major problem for agents is when they fail to render a universal premise effective at motivating a particular action in accordance with that premise. 2) There are two reasons this occurs: Precipitancy and Weakness. 3) Precipitancy and Weakness can be prevented by gaining a fuller understanding of our beliefs and commitments. This comparison should make clear that (...) akrasia is certainly not absent from Epictetus. Rather a very Aristotelian understanding of why we fail to act in accordance with what we take to be in our own best interests remains at the center of his ethics. (shrink)

This chapter first introduces naturalistic approaches to ethics more generally and distinguishes methodological ethical naturalism (the focus of this chapter), from metaphysical ethical naturalism. The second part then discusses evolutionary ethics as a specific variant of methodological ethical naturalism. After introducing the concepts of evolutionary theory that are relevant for evolutionary ethics, I will sketch the history of evolutionary ethics, which offers an interesting lesson about why it became a controversial topic, and then focus on four central questions about ethics (...) that can be approached from within the framework of evolutionary ethics: 1. What should we do? 2. Why are we moral? 3. Are there moral facts? 4. Can we have justified moral beliefs and moral knowledge? (shrink)

Many philosophers have suspected that the normative importance of morality depends on moral realism. In this paper, I defend a version of this suspicion: I argue that if teleological forms of moral realism, those that posit an objective purpose to human life, are true, then we gain a distinctive kind of reason to do what is morally required. I argue for this by showing that if these forms of realism are true, then doing what is morally required can provide a (...) life with meaning, which is a widespread human need. I also argue that rival meta-ethical views, like anti-realism or non-naturalist realism, cannot make morality meaning-conferring in this way. (shrink)

In this essay, I examine four different reasons for thinking that political dissent has epistemic value. The realization of this epistemic value hinges in part on what I’ll loosely call the epistemic environment, or the environment in which individuals come to believe, reason, inquire, and debate. In particular, to the degree that our social practices encourage and even embody an attitude of epistemic arrogance, the epistemic value of dissent will be difficult to realize. Ironically, it is precisely then that dissent (...) is most often needed. (shrink)

A standard way to challenge convergence-based accounts of inductive success is to claim that they are too weak to constrain inductive inferences in the short run. We respond to such a challenge by answering some questions raised by Juhl (1994). When it comes to predicting limiting relative frequencies in the framework of Reichenbach, we show that speed-optimal convergence—a long-run success condition—induces dynamic coherence in the short run.

Commentators disagree about the extent to which Kant’s ethics is compatible with consequentialism. A question that has not yet been asked is whether Kant had a view of his own regarding the fundamental difference between his ethical theory and a broadly consequentialist one. In this paper I argue that Kant does have such a view. I illustrate this by discussing his response to a well-known objection to his moral theory, namely that Kant offers an implicitly consequentialist theory of moral appraisal. (...) This objection was most famously raised by Mill and Schopenhauer, but also during Kant’s time by Pistorius and Tittel. I show that Kant’s response to this objection in the second Critique illustrates that he sees the fundamental difference between his moral theory and a broadly consequentialist one to be one that concerns methodology.

The Stoic Epictetus famously criticizeshis students for studying Stoicism as ‘mere theory’ and encouraged them to add training to their educational program. This is made all the more interesting by the fact that Epictetus, as a Stoic, was committed to notion that wisdom is sufficient to be virtuous, so theory should be all that’s required to achieve virtue. How are we then to make sense of Epictetus criticism of an overreliance on theory, and his insistence on adding training? This paper (...) argues that this tension can be resolved through an appeal to the metaphor of ‘digesting theory’. Epictetus discusses the digestion of theory in three parts of his existent work. While the use of digestion as a metaphor for moral progress in Epictetus has been noted, an explanation as to exactly what this process consists of has yet to be provided. This paper attempts to provide such an account. I argue that digestion consists of assimilating what we have learnt conceptually, at the level of general principles, into specific beliefs concerning existent objects. I argue further that this process of digestion can only be achieved through what Epictetus calls training (askesis). (shrink)

The debate about scientific realism is concerned with the relation between our scientific theories and the world. Scientific realists argue that our best theories or components of those theories correspond to the world. Anti-realists deny such a correspondence. Traditionally, this central issue in the philosophy of science has been approached by focusing on the theories themselves (e.g., by looking at theory change or the underlying experimental context). I propose a relatively unexplored way to approach this old debate. In addition to (...) focusing on the theory, we should focus on the theorizer. More precisely, in order to determine on which component of a theory we should hinge a realist commitment, we should analyze the cognitive processes underlying scientific theorizing. In this paper I do just that. Drawing from recent developments in the cognitive sciences and evolutionary epistemology, I formulate some tentative conclusions. The aim of this paper is not so much to defend a particular position in the debate on scientific realism but to showcase the value of taking a cognitive perspective in the debate. (shrink)

We review existing strategies for bringing modal intuitions to bear against materialist theories of consciousness, and then propose a new strategy. Unlike existing strategies, which assume that imagination (suitably constrained) is a good guide to modal truth, the strategy proposed here makes no assumptions about the probative value of imagination. However, unlike traditional modal arguments, the argument developed here delivers only the conclusion that we should not believe that materialism is true, not that we should believe that it is false.

Paradoxes have played an important role both in philosophy and in mathematics and paradox resolution is an important topic in both fields. Paradox resolution is deeply important because if such resolution cannot be achieved, we are threatened with the charge of debilitating irrationality. This is supposed to be the case for the following reason. Paradoxes consist of jointly contradictory sets of statements that are individually plausible or believable. These facts about paradoxes then give rise to a deeply troubling epistemic problem. (...) Specifically, if one believes all of the constitutive propositions that make up a paradox, then one is apparently committed to belief in every proposition. This is the result of the principle of classical logical known as ex contradictione (sequitur) quodlibetthat anything and everything follows from a contradiction, and the plausible idea that belief is closed under logical or material implication (i.e. the epistemic closure principle). But, it is manifestly and profoundly irrational to believe every proposition and so the presence of even one contradiction in one’s doxa appears to result in what seems to be total irrationality. This problem is the problem of paradox-induced explosion. In this paper it will be argued that in many cases this problem can plausibly be avoided in a purely epistemic manner, without having either to resort to non-classical logics for belief (e.g. paraconsistent logics) or to the denial of the standard closure principle for beliefs. The manner in which this result can be achieved depends on drawing an important distinction between the propositional attitude of belief and the weaker attitude of acceptance such that paradox constituting propositions are accepted but not believed. Paradox-induced explosion is then avoided by noting that while belief may well be closed under material implication or even under logical implication, these sorts of weaker commitments are not subject to closure principles of those sorts. So, this possibility provides us with a less radical way to deal with the existence of paradoxes and it preserves the idea that intelligent agents can actually entertain paradoxes. (shrink)

Reasoning from a naturalistic perspective, viewing the mind as an evolved biological organ with a particular structure and function, a number of influential philosophers and cognitive scientists claim that science is constrained by human nature. How exactly our genetic constitution constrains scientific representations of the world remains unclear. This is problematic for two reasons. Firstly, it often leads to the unwarranted conclusion that we are cognitively closed to certain aspects or properties of the world. Secondly, it stands in the way (...) of a nuanced account of the relationship between our cognitive and perceptual wiring and scientific theory. In response, I propose a typology or classification of the different kinds of biological constraints and their sources on science. Using Boden’s notion of a conceptual space, I distinguish between constraints relating to the ease with which we can reach representations within our conceptual space and constraints causing possible representations to fall outside of our conceptual space. This last kind of constraints does not entail that some aspects or properties of the world cannot be represented by us – as argued by advocates of ‘cognitive closure’ – merely that some ways of representing the world are inaccessible to us. It relates to what Clark and Rescher have framed as ‘the alien scientist hypothesis’. The purpose of this typology is to provide some much needed clarity and structure to the debate about biological constraints on science. (shrink)

This paper has three interdependent aims. The first is to make Reichenbach’s views on induction and probabilities clearer, especially as they pertain to his pragmatic justification of induction. The second aim is to show how his view of pragmatic justification arises out of his commitment to extensional empiricism and moots the possibility of a non-pragmatic justification of induction. Finally, and most importantly, a formal decision-theoretic account of Reichenbach’s pragmatic justification is offered in terms both of the minimax principle and the (...) dominance principle.

This paper contains an argument to the effect that possible worlds semantics renders semantic knowledge impossible, no matter what ontological interpretation is given to possible worlds. The essential contention made is that possible worlds semantic knowledge is unsafe and this is shown by a parallel with the preface paradox.

Existentialism claims that propositions that directly refer to individuals depend on those individuals for their existence. I argue for two points regarding Existentialism. First, I argue that recent accounts of Existentialism run into difficulties accommodating the possibility of there being a lonely alien electron. This problem is distinct from one of the better-known alien problems—concerning iterated modal properties of aliens—and can’t be solved using a standard response to the iterated case. Second, though the lonely alien electron problem might seem to (...) be reason to reject the sort of Existentialist view at hand, there’s a plausible way to preserve the view: accept the existence of possible worlds that directly refer to individuals that don’t exist in those worlds. Such a solution might seem incompatible with Existentialism, but I show that Existentialists can avoid the incompatibility and should find the resulting view plausible. (shrink)

A perceptual realism that is naive in a good way must be naively realistic about world and mind. But contemporary self-described naive realists often have trouble acknowledging that both the good cases of successful perception and the bad cases of illusion and hallucination involve internal experiential states with intentional contents that present the world as being a certain way. They prefer to think about experience solely in relational terms because they worry that otherwise we won’t be able to escape from (...) radical skepticism. I argue that experiential relations to objects require that their subjects be in internal experiential states. But this does not mean that these states are our epistemological starting point which can be known independently of any knowledge of the external world. We do escape the epistemological predicament of radical skepticism because the good cases are primary over the bad ones. But this is not because the good cases alone provide reasons for belief, but because we do not need a reason to think we are in a good case, but do need a reason to think we are not, and such a reason must come from a good case. So bad cases can only be thought of as deviations from good cases. And we can only understand experiences as states with contents distinct from their objects and present in good and bad cases once we understand misrepresentation, that is, bad cases, and therefore only as we ascribe knowledge of the external world to ourselves.

In this essay we argue for the Janus-faced nature of hope. We show that attempts to sanitise the concept of hope either by separating it conceptually from other phenomena such as wishful thinking, or, more generally, by seeking to minimise the negative aspects of hope, do not help us to understand the nature of hope and its functions as regards religion. Drawing on functional accounts of religion from Clifford Geertz and Tamas Pataki, who both—in their different ways—see the function of (...) religion in terms of its capacity to satisfy deep psychological needs, we demonstrate that religion uniquely positions itself with regard to hope’s two faces, simultaneously exploiting positive and negative aspects of hope.

_ Source: _Volume 95, Issue 3, pp 368 - 413 Frege famously maintained that concepts are not objects. A key argument of Frege’s for this view is, in outline, as follows: if we are to account for the unity of thought, concepts must be deemed _unsaturated_; since objects are, by contrast, saturated entities, concepts cannot be objects. The author investigates what can be made of this argument and, in particular, of the unsaturated/saturated distinction it invokes. Systematically exploring a range of (...) reconstructions suggested by Frege’s writings, and drawing on contemporary work, the author illustrates that no plausible reconstruction is forthcoming. In essence, it is altogether unclear how to simultaneously substantiate, on the one hand, the claim that unsaturated entities must be recognized in order to account for unity and, on the other, the claim that unsaturatedness is incompatible with objecthood.
