In replying to certain objections to the existence of God, Robert Adams, Bruce Langtry, and Peter van Inwagen assume that God can appropriately choose a suboptimal world, a world less good than some other world God could have chosen. A number of philosophers, such as Michael Slote and Klaas Kraay, claim that these theistic replies are therefore committed to the claim that satisficing can be appropriate. Kraay argues that this commitment is a significant liability. I argue, however, that the relevant (...) defenses of theism are committed to the appropriateness of, not satisficing, but motivated submaximization. When one submaximizes with motivation, one aims at the optimum but accepts the good enough because of a countervailing consideration. When one satisfices, one aims at the good enough and chooses the good enough because it realizes her aim at the good enough. While commitment to the appropriateness of satisficing may be a significant liability, commitment to the appropriateness of motivated submaximization is not. (shrink)

The church-funded CARFO or KARFO (Afrikaans Christian Filmmaking Organisation) was established in 1947, and aimed to ‘[socialise] the newly urbanized Afrikaner into a Christian urban society’ (Tomaselli 1985:25; Paleker 2009:45). This initiative was supported and sustained by the Dutch Reformed Church (DRC), which had itself been part of the sociopolitical and ideological fabric of Afrikaans religious life for a while and would guide Afrikaners through tensions between religious conservatism and liberalism and into apartheid. Given Afrikaans cinema’s ties with Christian religious (...) and political conservatism, we explore the role – even the centrality – of the Afrikaans church in cultural activity before 1994, and then after 1994. Here, Afrikaans church is an inclusive term that brings together various denominations of Afrikaans-speaking churches, but which mainly suggests the domination of the DRC. After establishing the role of the Afrikaans church in the way described above, we move towards the primary focus of our study: exploring the representation of clergy in the contemporary Afrikaans film Faan se Trein in order to describe certain theological implications of this representation. With reference to Faan se Trein, our article notes and comments on the shifts that have occurred in clergy representation in Afrikaans cinema over the past decades. Osmer’s four tasks of practical theology, namely, descriptive, interpretive, normative and strategic are used for theological reflection. With due contextual reference to Afrikaans film dramas such as Broer Matie [Brother Matie], Saak van Geloof [A Matter of Faith], Roepman [Stargazer], Stilte [Silence], Suiderkruis [Southern Cross] and Faan se Trein, we arrive at some preliminary conclusions about the representation of clergy in mainly contemporary Afrikaans cinema.

We were slightly concerned, upon having read Eric Winsberg, Jason Brennan and Chris Surprenant’s reply to our paper “Were Lockdowns Justified? A Return to the Facts and Evidence”, that they may have fundamentally misunderstood the nature of our argument, so we issue the following clarification, along with a comment on our motivations for writing such a piece, for the interested reader.

De auteurs van Aristoteles in actie menen dat nog iets anders essentieel is voor de vorming van professionals: de notie van praktische wijsheid. Zij ontlenen dit begrip aan de Griekse filosoof Aristoteles (384-322 v.Chr.). Aan de hand van verhalen en casussen uit de onderwijspraktijk laten zij zien hoe praktische wijsheid het fundament vormt onder alle vaardigheden en competenties en hoe je studenten in het middelbaar en hoger beroepsonderwijs praktische wijsheid bijbrengt. -/- Aristoteles in actie is samengesteld door Elke Müller.

Given the irrationality and failures of human behaviour in the face of ecocide, the majority of humankind appears either unable or unwilling to change self-destructive ways of life. Rejecting common accounts, the author suggests that the reasons for our stubborn resistance to change go well beyond cognitive dissonance or any standard political and economic explanations. Nor is the answer to be found in human history alone. The driving forces underlying that resistance, the author argues, originate far back in evolutionary time (...) to the impulses governing all sentient creatures. -/- NB: The copy of this article is the final, pre-production version of the article published in the Architectural Research Quarterly.

Users of psychedelic drugs often report that their sense of being a self or ‘I’ distinct from the rest of the world has diminished or altogether dissolved. Neuroscientific study of such ‘ego dissolution’ experiences offers a window onto the nature of self-awareness. We argue that ego dissolution is best explained by an account that explains self-awareness as resulting from the integrated functioning of hierarchical predictive models which posit the existence of a stable and unchanging entity to which representations are bound. (...) Combining recent work on the ‘integrative self' and the phenomenon of self-binding with predictive processing principles yields an explanation of ego dissolution according to which self-representation is a useful Cartesian fiction: an ultimately false representation of a simple and enduring substance to which attributes are bound which serves to integrate and unify cognitive processing across levels and domains. The self-model is not a mere narrative posit, as some have suggested; it has a more robust and ubiquitous cognitive function than that. But this does not mean, as others have claimed, that the self-model has the right attributes to qualify as a self. It performs some of the right kinds of functions, but it is not the right kind of entity. Ego dissolution experiences reveal that the self-model plays an important binding function in cognitive processing, but the self does not exist. (shrink)

In his wide-ranging study of architecture and cultural evolution, Chris Abel argues that, despite progress in sustainable development and design, resistance to changing personal and social identities shaped by a technology-based and energy-hungry culture is impeding efforts to avert drastic climate change. The book traces the roots of that culture to the coevolution of Homo sapiens and technology, from the first use of tools as artificial extensions of the human body to the motorized cities spreading around the world, whose (...) uncontrolled effects are fast changing the planet itself. Advancing a new concept of the meme, called the 'technical meme', as the primary agent of cognitive extension and technical embodiment, Abel proposes a theory of the 'extended self' as a complex and diffuse outcome of that coevolution. Challenging conventional ideas of the self as a separate and autonomous being, the extended self, he explains, encompasses material and spatial as well as psychological and social elements, including the built environment and artifacts, and now reaches out into the virtual world of cyberspace. Drawing upon research into extended cognition and embodied minds from philosophy, psychology and the neurosciences, the book presents a new approach to environmental and cultural studies. N.B. This book was the winner of the International Committee of Architectural Critics 2017 Bruno Zevi Book Award by unanimous decision of the international jury. (shrink)

Recent clinical trials show that psychedelics such as LSD and psilocybin can be given safely in controlled conditions, and can cause lasting psychological benefits with one or two administrations. Supervised psychedelic sessions can reduce symptoms of anxiety, depression, and addiction, and improve well-being in healthy volunteers, for months or even years. But these benefits seem to be mediated by "mystical" experiences of cosmic consciousness, which prompts a philosophical concern: do psychedelics cause psychological benefits by inducing false or implausible beliefs about (...) the metaphysical nature of reality? This book is the first scholarly monograph in English devoted to the philosophical analysis of psychedelic drugs. Its central focus is the apparent conflict between the growing use of psychedelics in psychiatry and the philosophical worldview of naturalism. Within the book, Letheby integrates empirical evidence and philosophical considerations in the service of a simple conclusion: this "Comforting Delusion Objection" to psychedelic therapy fails. While exotic metaphysical ideas do sometimes come up, they are not, on closer inspection, the central driver of change in psychedelic therapy. Psychedelics lead to lasting benefits by altering the sense of self, and changing how people relate to their own minds and lives-not by changing their beliefs about the ultimate nature of reality. The upshot is that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism (the philosophical position that the natural world is all there is). Controlled psychedelic use can lead to genuine forms of knowledge gain and spiritual growth-even if no Cosmic Consciousness or transcendent divine Reality exists. Philosophy of Psychedelics is an indispensable guide to the literature for researchers already engaged in the field of psychedelic psychiatry, and for researchers-especially philosophers-who want to become acquainted with this increasingly topical field.

One of the main challenges confronting Humean accounts of natural law is that Humean laws appear to be unable to play the explanatory role of laws in scientific practice. The worry is roughly that if the laws are just regularities in the particular matters of fact (as the Humean would have it), then they cannot also explain the particular matters of fact, on pain of circularity. Loewer (2012) has defended Humeanism, arguing that this worry only arises if we fail to (...) distinguish between scientific and metaphysical explanations. However, Lange (2013, 2018) has argued that scientific and metaphysical explanations are linked by a transitivity principle, which would undercut Loewer's defense and re-ignite the circularity worry for the Humean. I argue here that the Humean has antecedent reasons to doubt that there are any systematic connections between scientific and metaphysical explanations. The reason is that the Humean should think that scientific and metaphysical explanation have disparate aims, and therefore that neither form of explanation is beholden to the other in its pronouncements about what explains what. Consequently, the Humean has every reason to doubt that Lange's transitivity principle obtains. (shrink)

Perceptual dogmatism holds that if it perceptually seems to S that P, then S thereby has prima facie perceptual justification for P. But suppose Wishful Willy's desire for gold cognitively penetrates his perceptual experience and makes it seem to him that the yellow object is a gold nugget. Intuitively, his desire-penetrated seeming can't provide him with prima facie justification for thinking that the object is gold. If this intuitive response is correct, dogmatists have a problem. But if dogmatists have a (...) problem, you do too (well, most of you anyway). Reliabilists have denounced dogmatism's cognitive penetration problems, but they have problems with cognitive penetration that are even worse. (shrink)

The doctrine of permanent sovereignty over natural resources is a hugely consequential one in the contemporary world, appearing to grant nation-states both jurisdiction-type rights and rights of ownership over the resources to be found in their territories. But the normative justification for that doctrine is far from clear. This article elucidates the best arguments that might be made for permanent sovereignty, including claims from national improvement of or attachment to resources, as well as functionalist claims linking resource rights to key (...) state functions. But it also shows that these defences are insufficient to justify permanent sovereignty and that in many cases they actually count against it as a practice. They turn out to be compatible, furthermore, with the dispersal of resource rights away from the nation-state which global justice appears to demand. (shrink)

Classical acquaintance theory is any version of classical foundationalism that appeals to acquaintance in order to account for non-inferential justification. Such theories are well suited to account for a kind of infallible non-inferential justification. Why am I justified in believing that I’m in pain? An initially attractive (partial) answer is that I’m acquainted with my pain. But since I can’t be acquainted with what isn’t there, acquaintance with my pain guarantees that I’m in pain. What’s less clear is whether, given (...) classical acquaintance theory, it’s possible to have non-inferential justification to believe something false. Classical acquaintance theorists try to make room for such a possibility, but I argue that the attempts of Richard Fumerton, Ali Hasan, and Evan Fales are inadequate. I’ll focus on introspective justification, but similar issues arise for a priori justification as well. (shrink)

The chapter introduces and characterizes the notion of fittingness. It charts the history of the relation and its relevance to contemporary debates in normative and metanormative philosophy and proceeds to survey issues to do with fittingness covered in the volume’s chapters, including the nature and epistemology of fittingness, the relations between fittingness and reasons, the normativity of fittingness, fittingness and value theory, and the role of fittingness in theorizing about responsibility. The chapter concludes with a brief discussion of issues to (...) do with fittingness that aren’t covered extensively by the volume’s chapters in order to indicate avenues for further research.

Inflationary cosmology has been widely accepted due to its successful predictions: for a “generic” initial state, inflation produces a homogeneous, flat, bubble with an appropriate spectrum of density perturbations. However, the discovery that inflation is “generically eternal,” leading to a vast multiverse of inflationary bubbles with different low-energy physics, threatens to undermine this account. There is a “predictability crisis” in eternal inflation, because extracting predictions apparently requires a well-defined measure over the multiverse. This has led to discussions of anthropic predictions (...) based on a measure over the multiverse, and an assumption that we are typical observers. I will give a pessimistic assessment of attempts to make predictions in this sense, emphasizing in particular problems that arise even if a unique measure can be found. (shrink)

In this paper, we present a survey of the development of the technique of argument diagramming covering not only the fields in which it originated - informal logic, argumentation theory, evidence law and legal reasoning – but also more recent work in applying and developing it in computer science and artificial intelligence. Beginning with a simple example of an everyday argument, we present an analysis of it visualised as an argument diagram constructed using a software tool. In the context of (...) a brief history of the development of diagramming, it is then shown how argument diagrams have been used to analyze and work with argumentation in law, philosophy and artificial intelligence.

Psychedelic ingestion and meditative practice are both ancient methods for altering consciousness that became widely known in Western society in the second half of the 20th century. Do the similarities begin and end there, or do these methods – as many have claimed over the years – share some deeper common elements? In this chapter I take a neurophilosophical approach to this question and argue that there are, indeed, deeper commonalities. Recent empirical studies show that psychedelics and meditation modulate overlapping (...) brain networks involved in the sense of self, salience, and attention; moreover, psychedelics can occasion lasting increases in “mindfulness-related capacities” for taking a non-reactive stance on one’s inner experience (e.g. Sampedro et al. 2017). The self-binding theory of psychedelic ego dissolution (Letheby and Gerrans 2017) offers a plausible explanation of these findings: by disrupting self-related beliefs implemented in high-level cortical networks, both psychedelics and meditation can “unbind” mental contents from one’s self-model, moving these contents along the continuum from phenomenal transparency to opacity (cf. Metzinger 2003). In other words, both psychedelics and meditation can expose and weaken our foundational beliefs about our own identity, allowing us to disidentify with these beliefs and see them as “just thoughts”. There are connections between these ideas and recent arguments suggesting that psychedelic use may have epistemic benefits consistent with philosophical naturalism (Letheby 2015, 2016, 2019). I conclude with a proposal: these connections may help in thinking about the putative epistemic benefits of meditation practice from a naturalistic perspective. (shrink)

Starting from two observations regarding nursing ethics research in the past two decades, namely, the dominant influence of both the empirical methods and the principles approach, we present the cornerstones of a foundational argument-based nursing ethics framework. First, we briefly outline the general philosophical–ethical background from which we develop our framework. This is based on three aspects: lived experience, interpretative dialogue, and normative standard. Against this background, we identify and explore three key concepts—vulnerability, care, and dignity—that must be observed in (...) an ethical approach to nursing. Based on these concepts, we argue that the ethical essence of nursing is the provision of care in response to the vulnerability of a human being in order to maintain, protect, and promote his or her dignity as much as possible.

Philosophers often treat racist and sexist slurs as a special sort of puzzle. What is the difference between a slur and its correlates? In attempting to answer this question, a second distinction has been overlooked: that between slurs and insults. What makes a term count as a slur? This is not an unnecessary taxonomical question as long as ableist terms such as ‘moron’ are dismissed as mere insults. Attempts to resolve the insult/slur distinction by considering the communicative content of slurs (...) are not promising. A better solution is offered by speech act theory, and this paper develops a novel way to describe ordinary slurring utterances as oppressive speech acts. This can both explain the difference between slurs and insults, and challenge the dismissal of ableist terms. (shrink)

Expanding his collected essays on architectural theory and criticism, Chris Abel pursues his explorations across disciplinary and regional boundaries in search of a deeper understanding of architecture in the evolution of human culture and identity formation. From his earliest writings predicting the computer-based revolution in customised architectural production, through his novel studies on 'tacit knowing' in design or hybridisation in regional and colonial architecture, to his radical theory of the 'extended self', Abel has been a consistently fresh and provocative (...) thinker, contesting both conventions and intellectual fashions. This revised third edition includes a new introduction and six additional chapters by the author covering a broad range of related topics, up to recent concerns with genetic design methods and virtual selves. Together with the former essays, the book presents a unique global perspective on the changing cultural issues and technologies shaping human identities and the built environment in diverse parts of the world, both East and West (from the book cover).

Do numbers exist? Do properties? Do possible worlds? Do fictional characters? Many metaphysicians spend time and effort trying to answer these and other questions about the existence of various entities. These inquiries have recently encountered opposition: a group of philosophers, drawing inspiration from Aristotle, have argued that many or all of the existence questions debated by metaphysicians can be answered trivially, and so are not worth debating. Our task is to defend existence questions from the neo-Aristotelians' attacks.

This paper accomplishes three goals. First, it reveals that God’s ethics has a radical satisficing structure: God can choose a good enough suboptimal option even if there is a best option and no countervailing considerations. Second, it resolves the long-standing worry that there is no account of the good enough that is both principled and demanding enough to be good enough. Third, it vindicates the key ethical assumption in the problem of evil without relying on the contested assumption that God’s (...) ethics is our ethics. (shrink)

The Neo-Moorean Deduction (I have a hand, so I am not a brain-in-a-vat) and the Zebra Deduction (the creature is a zebra, so isn’t a cleverly disguised mule) are notorious. Crispin Wright, Martin Davies, Fred Dretske, and Brian McLaughlin, among others, argue that these deductions are instances of transmission failure. That is, they argue that these deductions cannot transmit justification to their conclusions. I contend, however, that the notoriety of these deductions is undeserved. My strategy is to clarify, attack, defend, (...) and apply. I clarify what transmission and transmission failure really are, thereby exposing two questionable but quotidian assumptions. I attack existing views of transmission failure, especially those of Crispin Wright. I defend a permissive view of transmission failure, one which holds that deductions of a certain kind fail to transmit only because of premise circularity. Finally, I apply this account to the Neo-Moorean and Zebra Deductions and show that, given my permissive view, these deductions transmit in an intuitively acceptable way—at least if either a certain type of circularity is benign or a certain view of perceptual justification is false.

This paper is an enquiry into the logical, metaphysical, and physical possibility of time travel understood in the sense of the existence of closed worldlines that can be traced out by physical objects. We argue that none of the purported paradoxes rule out time travel either on grounds of logic or metaphysics. More relevantly, modern spacetime theories such as general relativity seem to permit models that feature closed worldlines. We discuss, in the context of Gödel's infamous argument for the ideality (...) of time based on his eponymous spacetime, what this apparent physical possibility of time travel means. Furthermore, we review the recent literature on so-called time machines, i.e., of devices that produce closed worldlines where none would have existed otherwise. Finally, we investigate what the implications of the quantum behaviour of matter for the possibility of time travel might be and explicate in what sense time travel might be possible according to leading contenders for full quantum theories of gravity such as string theory and loop quantum gravity.

This short article is a “conversation” in which an android, Mort, replies to Richard Marc Rubin’s android named Sol in “The Robot Sol Explains Laughter to His Android Brethren” (The Philosophy of Humor Yearbook, 2022). There Sol offers an explanation for how androids can laugh--largely a reaction to frustration and unmet expectations: “my account says that laughter is one of four ways of dealing with frustration, difficulties, and insults. It is a way of getting by. If you need to label (...) my conception of humor, you might call it an adjustment theory, or perhaps an accommodation theory” (Rubin 256). Mort is intrigued but has his doubts. Mort contends that synesthesia likely has something to do with how humans develop humor. Perhaps, he considers, human designers crossed the androids' sensory wires, allowing them to be able to smash up concepts that do not otherwise seem to fit together, reconstruct incongruities in a manner that is not nonsensical, express the aha-eureka moment of a serendipitous discovery, and even feel blue when they fail at a given task that we were expected to complete.

It may seem that epistemic and practical rationality weigh reasons differently, because ties in practical rationality tend to generate permissions and ties in epistemic rationality tend to generate a requirement to withhold judgment. I argue that epistemic and practical rationality weigh reasons in the same way, but they have different "default biases". Practical rationality is biased toward every option being permissible whereas epistemic rationality is biased toward withholding judgment's being required.

This article investigates the relationships between forms of humor that conjure up possible worlds and real-world social critiques. The first part of the article will argue that subversive humor, which is from or on behalf of historically and continually marginalized communities, constitutes a kind of aesthetic experience that can elicit enjoyment even in adversarial audiences. The second part will be a connecting piece, arguing that subversive humor can be constructed as brief narrative thought experiments that employ the use of fictionalized (...) scenarios to facilitate an open, playful attitude, encouraging a space for collaborative interpretation. This interaction between humorist and audience is an aesthetic experience that is enjoyable in and of itself, as the feelings of mirth are intrinsically valuable. But connected to the “Ha-ha!” experience of these sorts of humorous creations is an “Aha!” or potentially revelatory experience that is a mixture of cognitive comprehension and motivated (emotional) response. The third part of the article will attempt to go beyond the consciousness-raising element with an account of how such possible worlds created in the realm of imagination through subversive humor can bleed into the real world of flesh and blood people. Finally, an example of subversive humor will be analyzed. (shrink)

Many contemporary philosophers rate error theories poorly. We identify the arguments these philosophers invoke, and expose their deficiencies. We thereby show that the prospects for error theory have been systematically underestimated. By undermining general arguments against all error theories, we leave it open whether any more particular arguments against particular error theories are more successful. The merits of error theories need to be settled on a case-by-case basis: there is no good general argument against error theories.

It is natural to think that many of our beliefs are rational because they are based on seemings, or on the way things seem. This is especially clear in the case of perception. Many of our mathematical, moral, and memory beliefs also appear to be based on seemings. In each of these cases, it is natural to think that our beliefs are not only based on a seeming, but also that they are rationally based on these seemings—at least assuming there (...) is no relevant counterevidence. This piece is an introduction to a volume dedicated to the question of what the connection is between seemings and justified belief: under what conditions, if any, can a seeming justify its content?

The inductive argument from evil to the non-existence of God contains the premise that, probably, there is gratuitous evil. Some skeptical theists object: one's justification for the premise that, probably, there is gratuitous evil involves an inference from the proposition that we don't see a good reason for some evil to the proposition that it appears that there is no good reason for that evil, and they use a principle, "CORNEA," to block that inference. The common sense problem of evil (...) threatens the CORNEA move, because the common sense problem of evil does not involve any inference to justify the belief that there is gratuitous evil. In this paper, I argue that the common sense problem of evil doesn't avoid CORNEA. CORNEA, or a reformulated version of it, can still prevent one from having justification for the belief that there is gratuitous evil. (shrink)

This chapter provides an account of what dogmatism is, why the term matters, and how it applies to withholding judgment. Roughly, a person is dogmatic about P when a certain problematic personal investment—a superiority complex, broadly construed—biases their judgment concerning whether P. The term dogmatism and its cognates matter because of their social function. To accuse you of dogmatism is to signal how you are to be treated: your judgment or behavior needs to be “brought down to earth,” so that (...) you have a more accurate view of yourself or so you stop treating others as less important or less than. Withholding judgment can be dogmatic in the same way that belief is dogmatic. Belief (withholding) is dogmatic just when the relevant problematic personal investment results in biases that keep a person stuck in that belief (withholding). (shrink)

The category of sympathy marks a number of basic divisions in early modern approaches to action explanations, whether for human agency or for change in the wider natural world. Some authors were critical of using sympathy to explain change. They call such principles “unintelligible” or assume they involve “mysterious” action at a distance. Others, including Margaret Cavendish, Anne Conway, and Gottfried Wilhelm Leibniz, appeal to sympathy to capture natural phenomena, or to supply a backbone to their metaphysics. Here I discuss (...) how concerns about sympathetic actions form at least a partial background for differing seventeenth-century conceptions of what it is to explain action. I argue that critics of sympathy generally insist on an “atomistic” approach to action explanation, which makes primitively relational phenomena come out as problematic. Proponents of sympathy, by contrast, allow for a more holistic approach to action explanation, which allows for such basic connections. Hence, divergent attitudes toward sympathetic action in part explain differences in approaches to explanation. I conclude by showing how some of these core concerns fade into the background when in the eighteenth-century sympathy gets psychologised and individualised. (shrink)

This draft preprint presents a nine step argument for “Connectionist Structuralism” (CS), an account of the ontology of abstract objects that is neither purely nominalist nor purely platonist. CS is a common, often implicit assumption in parts of the artificial intelligence literature, but such discussions have not presented formal accounts of the position or engaged with metaphysical issues that potentially undermine it. By making the position legible and presenting an initial case for it, we hope to support a constructive dialogue (...) between AI researchers and philosophers of metaphysics that helps both sides to refine the position. -/- CS proposes that each abstract object we can draw on in human analysis corresponds to a particular subset of an individual person’s brain structure whose functionality is isomorphic to a subset of the nodes and connections in a suitable connectionist network. In other words, abstract objects are physically realised, but in individual brains, rather than only in the referent objects (pure nominalism) or in metaphysical universals (pure platonism). -/- This paper’s minimum claim is that CS can account for all abstract object predicables regarding sensible properties, such as “is red” or “is a square”. Using evidence from cognitive neuroscience, machine learning, and evolutionary biology, as well as a fully traceable toy example, we describe how CS can support our core cognitive uses of such sensible properties and can account for our core phenomenal experiences of them. In the former, CS provides sufficient albeit imperfect inferential safety, whose limitations are argued to strengthen rather than weaken the case for CS as describing human behaviour. In the latter, four target phenomenal features are accounted for – abstract objects as feeling intangible, non-located, transparent, and unchanging - along with accounts for further phenomena such as semantic refinement, the Stroop effect, synaesthesia, semantic clarity, sensory overload, and satiation. -/- Our minimum claim concerns the day-to-day usage and felt experience of abstract objects, but we suggest also an extended claim in which CS can form the basis of a pragmatic sufficient logic. As such, the initial outline of a response is provided for five common objections to positions that seek to ground abstract objects without reference to metaphysically stand-alone universals: referential opacity; identity of indiscernibles; infinite regression; non-physical concepts; and necessary truths. These outlines lay the foundation for (but do not seek to formally demonstrate) an extended CS account that addresses other abstract objects, including issues relating to their use in mathematics and formal logic. -/- The CS account leads to a four-layer hierarchy of similarity for whether your “red” is the same as mine. Considering both semantic and phenomenal similarity, we conclude that our “reds” are likely non-identical but can be made close enough for practical purposes. Finally, we describe how future work could elaborate CS as a metaphysical project and how confidence in it could be tested through empirical research. (shrink)

This paper responds to a new objection, due to Ben Bramble, against attitudinal theories of sensory pleasure and pain: the objection from unconscious pleasures and pains. According to the objection, attitudinal theories are unable to accommodate the fact that sometimes we experience pleasures and pains of which we are, at the time, unaware. In response, I distinguish two kinds of unawareness and argue that the subjects in the examples that support the objection are unaware of their sensations in only a (...) weak sense, and this weak sort of unawareness of a sensation does not preclude its being an object of one’s attitudes.

The metaphor of weighing reasons brings to mind a single (double-pan balance) scale. The reasons for φ go in one pan and the reasons for ~φ go in the other. The relative weights, as indicated by the relative heights of the two pans of the scale, determine the deontic status of φ. This model is simple and intuitive, but it cannot capture what it is to weigh reasons correctly. A reason pushes the φ pan down toward permissibility (has justifying weight) (...) only insofar as it pushes the ~φ pan up toward impermissibility (has requiring weight). Thus, Single Scale is committed to Single Proportion (first pass): all reasons have the same proportion of justifying and requiring weight. Many normative theories reject Single Proportion, and they are not thereby confused about how to weigh reasons. One can be mistaken about the weight of a reason without being confused about how reasons are to be weighed. Single Scale is problematic, not because it appeals to the image of a scale, but because it appeals to the image of a single scale. We need two scales to capture what it is to weigh reasons correctly. (shrink)

L.S. Vygotsky’s “regulative” account of the development of human thinking hinges on the centralization of “directive” speech acts (commands or imperatives). With directives, one directs the activity of another, and in turn begins to “self-direct” (or self-regulate). It’s my claim that Vygotsky’s reliance on directives de facto keeps his account stuck at Tomasello's level of individual intentionality. Directive speech acts feature prominently in Tomasello’s developmental story as well. But Tomasello has the benefit of accounting for a functional differentiation in directive (...) communication—i.e., in collaborative activity, the command gives way to both the request and informational assertion. Lacking such differentiation, Vygotsky’s account runs the risk of playing to a rather strident conception of the socius, one more Machiavellian than Marxist. (shrink)

The intuitions at the core of environmental ethics and of other neglected value realms put pressure on traditional anthropocentric ethics based on monistic value theories. Such pressure is so severe that it has led many to give up on the idea of monistic value theories altogether. I argue that value monism is still preferable to value pluralism and that, indeed, these new challenges are opportunities to vastly improve impoverished traditional theories. I suggest an alternative monistic theory, Richness Theory, and show (...) how it provides an opportunity to capture the needs of both environmental ethics and of our traditional ethics. (shrink)

This essay aims to provide a self-contained introduction to time in relativistic cosmology that clarifies both how questions about the nature of time should be posed in this setting and the extent to which they have been or can be answered empirically. The first section below recounts the loss of Newtonian absolute time with the advent of special and general relativity, and the partial recovery of absolute time in the form of cosmic time in some cosmological models. Section II considers (...) the beginning and end of time in a broader class of models in which there is not an analog of Newtonian absolute time. As we will see, reasonable physical assumptions imply that the universe is finite to the past, and Section III turns to consideration of the “beginning” itself. We critically review conventional wisdom that a “singularity” reveals flaws in general relativity and briefly assess ways of avoiding the singularity. (shrink)

A "good" arguer is like an architect with a penchant for civil and civic engineering. Such an arguer can design and present their reasons artfully about a variety of topics, as good architects do with a plenitude of structures and in various environments. Failures in this are rarely hidden for long, as poor constructions reveal themselves, often spectacularly, so collaboration among civical engineers can be seen as a virtue. Our logical virtues should be analogous. When our arguments fail due to (...) being uncivil and demagogic, since we inhabit the arguments we build, we are all crushed beneath our flawed reasoning. This mixed metaphor takes us to a self-referential analysis of argumentation, analogy, and humor. I argue that good argumentation strives to collaboratively convince rather than belligerently persuade. A convincing means toward this end is through humorous analogical arguments, whether the matter at hand is ethical, logical, theological, phenomenological, epistemological, metaphysical, political, or about baseball.

Looking out the window, I see that it's raining outside. Do I know that it’s raining outside? According to proponents of the Entailment Thesis, I do. If I see that p, I know that p.

But recently, some philosophers (McDowell 2002, Turri 2010, Pritchard 2011, 2012) have argued that the Entailment Thesis is false. On their view, we can see p and not (...) know that p. In this paper, I argue that their arguments are unsuccessful. (shrink)

In this précis I summarise the main ideas of my book Philosophy of Psychedelics. The book discusses philosophical issues arising from the therapeutic use of “classic” psychedelic drugs such as psilocybin and LSD. The book is organised around what I call the Comforting Delusion Objection to psychedelic therapy: the concern that this novel and promising treatment relies essentially on the induction of non-naturalistic metaphysical beliefs, rendering it epistemically objectionable. I begin the précis by summarizing material from chapters two and three (...) of the book, which review evidence for the therapeutic efficacy of psychedelics, and the facts about their clinical use that prompt the Comforting Delusion Objection. I then summarize materials from chapters four and five of the book, which argue that psychedelic therapy works neither by experience-independent processes of neuroplasticity, nor by inducing non-naturalistic metaphysical ideations, but by altering mental representations of the self. Next, I summarise the specific, speculative account of how this might work that is developed in chapters six and seven of the book. This account is based on the predictive processing theory of brain function and the self-binding theory of self-representation. Chapters eight and nine of the book argue, on the basis of this account, that psychedelic therapy can have significant epistemic and spiritual benefits that are compatible with a naturalistic worldview. I summarize this material, and then, finally, the overall conclusions about psychedelic therapy drawn in the tenth and final chapter of the book. (shrink)

This chapter explores whether and when experience can be evidence. It argues that experiences can be evidence, and that this claim is compatible with just about any epistemological theory. It evaluates the most promising argument for the conclusion that certain experiences (e.g., seeming to see) are always evidence for believing what the experiences represent. While the argument is very promising, one premise needs further defense. The argument also depends on a certain connection between reasonable belief and the first person perspective.

In this incisive study of the biological and cultural origins of the human self, the author challenges readers to re-think ideas about the self and consciousness as being exclusive to humans. In their place, he expounds a metatheoretical approach to the self as a purposeful system of extended cognition common to animal life: the invisible medium maintaining mind, body and environment as an integrated 'field of being'. Supported by recent research in evolutionary and developmental studies together with related discoveries in (...) animal behavior and the neurosciences, the author examines the factors that have shaped the evolution of the animal self across widely different species and times, through to the modern, technologically enmeshed human self; the differences between which are presented as relations of degree rather than absolute differences. Much like our primitive ancestors, he contends, routine human behaviour is governed more by unconscious instinct than self-conscious rationality, and is generally resistant to any major changes in customary habits of life, until compelled in time to do so. However, in extreme and rapidly evolving circumstances, as with climate change, tardy responses may become so detached from reality as to constitute an actual threat to survival. (shrink)

What should we do when faced with powerful theoretical arguments that support a severe change in our personal beliefs and commitments? For example, what should new parents do when confronted by unanswered anti-natalist arguments, or two lovers vexed by social theory that apparently undermines love? On the one hand, it would be irrational to ignore theory just because it’s theory; good theory is evidence, after all. On the other hand, factoring in theory can be objectifying, or risks unraveling one's life, (...) fracturing one's identity or social relations. Sometimes, then, following the evidence where it apparently leads would mean not merely changing what we think but who we are. Some might say that there’s something right about the thought that theory can bear on what we ought to believe, it’s just that when we work with full beliefs, only then do we seriously risk having to substantially alter our doxastic economy when pressed by exceptional theoretical arguments. When we work with partial beliefs, however, this risk is greatly diminished. Others will say that we can advocate or champion revisionary positions whilst rationally retaining our pre-theoretical personal convictions. Still others will argue that we should adopt a Moorean posture towards the revisionary arguments. I argue that each response is inadequate, and argue instead that we are permitted to bracket certain kinds of theoretical evidence against our beliefs because of the personal and ethical risks born out of giving them serious consideration. In turn, some of philosophy's doxastic influence is constrained by its attendant ethical risks: the personal enjoys a partial insulation from the theoretical. I close by addressing what this means for practicing philosophers. (shrink)

Dale Dorsey’s wide-ranging A Theory of Prudence contains ideas and arguments worthy of our attention on quite a variety of self-interest-related normative topics. In this essay I focus on Dorsey’s theory of prudential rationality, which is designed to deliver a negative answer to this essay’s titular question. Dorsey’s negative answer may be more intuitive, but I believe the positive answer is more defensible. From the perspective of prudence, it is just as reasonable to change your desires to fit the world (...) as it is to change the world to fit your desires. (shrink)

Recent scientific research suggests that altered states of consciousness induced by classic psychedelic drugs can cause durable psychological benefits in both healthy and patient populations. The phenomenon of ‘psychedelic transformation’ has many philosophically provocative aspects, not least of which is the claim commonly made by psychedelic subjects that their transformation is centrally due to some kind of learning or knowledge gain. Can psychedelic experiences really be a source of knowledge? From the vantage point of philosophical materialism or naturalism, a negative (...) answer is tempting because psychedelic subjects often claim drug-facilitated knowledge of non-natural, transcendent realities. This fact, combined with common conceptions of these drugs as ‘hallucinogenic’ or ‘psychotomimetic’, invites the conclusion that claims of epistemic benefit from psychedelic experience are uniformly false. However, several recent proposals have been made in the literature about naturalistically acceptable epistemic benefits that might arise from psychedelic use. In this chapter I review these proposals, classifying them in accordance with standard epistemological categories, and discuss the arguments for and against them. I also offer some suggestions for future research. (shrink)
