In this paper, I critically assess the enactive account of visual perception recently defended by Alva Noë (2004). I argue inter alia that the enactive account falsely identifies an object’s apparent shape with its 2D perspectival shape; that it mistakenly assimilates visual shape perception and volumetric object recognition; and that it seriously misrepresents the constitutive role of bodily action in visual awareness. I argue further that noticing an object’s perspectival shape involves a hybrid experience combining both perceptual and imaginative (...) elements—an act of what I call ‘make‐perceive’. (shrink)

Existentialist accounts maintain that visual phenomenal content takes the logical form of an existentially quantified sentence. These accounts do not make phenomenal content specific enough. Singularist accounts posit a singular content in which the seen object is a constituent. These accounts make phenomenal content too specific. My account gets the specificity of visual phenomenal content just right. My account begins with John Searle's suggestion that visual experience represents an object as seen, moves this relation outside the scope of the existential (...) quantifier and then replaces it with the relation of objects being ‘present as accessible’, as described by Alva Noë.

Ita La recensione presenta la prospettiva enattivista difesa da Alva Noë, e ne discute alcuni aspetti specifici. Il pensiero, la coscienza e la cognizione non sono pienamente comprensibili, secondo l’enattivismo di Noë, senza un’adeguata considerazione del ruolo ricoperto dal corpo e dall’ambiente. Sarebbe quindi sbagliato continuare a pensare che il cervello da solo sia responsabile dei processi cognitivi umani: il programma che ricerca i correlati neurali della coscienza sarebbe quindi destinato al fallimento dal principio, perché tralascia in partenza corpo (...) e ambiente; i programmi di ricerca nel campo dell’intelligenza artificiale sarebbero ugualmente compromessi, non solo con una concezione computazionalista della cognizione, ma anche con la vecchia idea che un cervello artificiale sia sufficiente alla cognizione quanto un cervello naturale. Di seguito si prendono in esame due prospettive sperimentali su cui Noë fa grande affidamento: gli studi sulla plasticità neurale dei furetti svolti da Mriganka Sur e altri, e la realizzazione di un sistema di sostituzione visuo-tattile da parte di Paul Bach-Y-Rita. Per Noë si tratta di elementi cruciali in supporto alla propria prospettiva: in realtà, come emerge dalla breve analisi, l’attribuire loro un significato così chiaro e univoco pro-enattivismo è qualcosa di molto meno scontato. Infine, segue un breve bilancio del libro di Noë, dove gli elementi d’interesse del volume sono presentati insieme all’individuazione di alcuni punti deboli, che il testo condivide con la gran parte degli studi che in vario modo fanno leva sull’intuizione legata all’embodiement: da un lato una difficoltà strutturale riguarda la possibilità di identificare con chiarezza gli elementi costitutivi del mentale; dall’altro lato, il riferimento a forme di esternalismo radicale sembra ugualmente comportare diversi problemi. -/- Abstract Eng The review presents Alva Noë’s enactivist view, and aims at discussing some of its ideas. Thought, consciousness, and cognition are not understandable, Noë claims, without taking into proper consideration the role played by the body and the environment. It would be wrong indeed to go on thinking that our brain alone is responsible for human cognitive processes: the program searching for the neural correlates of consciousness is hopeless in principle, because it neglects from the beginning the body and the environment; research programs in artificial intelligence are as well compromised, not only with a computationalist view of cognition, but also with the old idea that an artificial brain will suffice for cognition just like a natural one. Thereafter, two experimental perspectives, that Noë uses to support his view, are examined: Mriganka Sur’s studies on neural plasticity of ferrets, and Paul Bach-Y-Rita’s tactile-visual substitution system. Noë argues that these results are crucial in supporting his view, but, as the discussion highlights, their pro-enactivism meaning is not so clear and unambiguous. Finally, a balance of the book follows, where the many elements of interest are presented together with the acknowledgment of some weak points, that the book shares with the majority of the proposals that deal with the embodiment’s insight: on the one hand, a structural difficulty concerns the possibility to identify clearly the constitutive elements of the mental; on the other hand, the reference to radical versions of externalism seems to entail many difficulties as well.

Review of Alva Noe's Strange Tools for the journal, Teaching Philosophy.

The idea of dreams being mere internal artifacts of the mind does not seem to be essential to externalism and extended mind theories, which seem as if they would function as well without this additional assumption. The Many Bubble Interpretation could allow a simpler rationale to externalist theories, which may be even simpler if the assumption that dreams have no worthwhile content outside the mind is omitted.

Strange Tools foregoes stolid conventions of professional philosophy, laudably broadening the book’s appeal to accommodate a popular audience. However, Noë’s manner of glossing over complex issues about art does not necessarily render these topics intelligible to philosophical novices. Instead, his oversimplifications will tend to confirm naïve notions that art is straightforward – a common misconception that a foray into philosophy of art ought to dispel, not corroborate.

According to “actionism” (Noë 2010), perception constitutively depends on implicit knowledge of the way sensory stimulations vary as a consequence of the perceiver’s self-movement. My aim in this contribution is to develop an alternative conception of the role of action in perception present in the work of Gareth Evans using resources provided by Ruth Millikan’s biosemantic theory of mental representation.

According to proponents of the sensorimotor contingency theory of perception (Hurley & Noë 2003, Noë 2004, O’Regan 2011), active control of camera movement is necessary for the emergence of distal attribution in tactile-visual sensory substitution (TVSS) because it enables the subject to acquire knowledge of the way stimulation in the substituting modality varies as a function of self-initiated, bodily action. This chapter, by contrast, approaches distal attribution as a solution to a causal inference problem faced by the subject’s perceptual systems. (...) Given all of the available endogenous and exogenous evidence available to those systems, what is the most probable source of stimulation in the substituting modality? From this perspective, active control over the camera’s movements matters for rather different reasons. Most importantly, it generates proprioceptive and efference-copy based information about the camera’s body-relative position necessary to make use of the spatial cues present in the stimulation that the subject receives for purposes of egocentric object localization.

This is my reply to commentators in the symposium on my book, GAMES: AGENCY AS ART. The symposium features commentary by Thomas Hurka, Quill Kukla, and Alva Noe, and originally appeared in Analysis 81 (2).

I argue that Husserl’s transcendental account of the role of the lived body in sense-making is a precursor to Alva Noë’s recent work on the enactive, embodied mind, specifically his notion of “sensorimotor knowledge” as a form of embodied sense-making that avoids representationalism and intellectualism. Derrida’s deconstructive account of meaning—developed largely through a critique of Husserl—relies on the claim that meaning is structured through the complication of the “interiority” of consciousness by an “outside,” and thus might be thought to (...) lend itself to theories of mind such as Noë’s that emphasize the ways in which sense-making occurs outside the head. But while Derrida’s notion of “contamination” rightly points to an indeterminateness of meaning in an outside, extended, concrete lived world, he ultimately reduces meaning to a structure of signification. This casts indeterminateness in terms of absence, ignoring the presence of non-linguistic phenomena of embodied sense-making central to both the contemporary enactivist program and to the later Husserl, who is able to account for the indeterminateness of meaning in lived experience through his distinction between sense and more exact linguistic meaning. Husserl’s transcendental theory of meaning also allows for a substantive contribution to sense-making from the side of the perceived object—an aspect missing from Noë’s account. Thus, in contrast to Derrida and to Noë, Husserl accounts for sense-making in terms of both the lived body and the lived world. (shrink)

Plausibly, any adequate theory of perception must (a) solve what Alva Noë calls 'the problem of perceptual presence,' and (b) do justice to the direct realist idea that what is given in perception are garden-variety spatiotemporal particulars. This paper shows that, while Noë's sensorimotor view arguably satisfies the first of these conditions, it does not satisfy the second. Moreover, Noë is wrong to think that a naïve realist approach to perception cannot handle the problem of perceptual presence. Section three (...) of this paper develops a version of naïve realism that meets both of the adequacy conditions above. This paper thus provides strong considerations in favor of naïve realism.

In this paper, I defend an account of how perceptual experience can bear rational relation to our empirical thought. In the first part, I elaborate two claims that are central for the justificational role of perceptual experience, namely, the claim that perception and belief share the same kind of content, and the claim that perception is independent from belief. At first sight, these claims seem not to be compatible, since the first one seems to require the truth of content conceptualism, (...) while the second one seems to require its falsity. In the second part, based on Alva Noë's actionist theory of perception, I argue in favor of a less intellectualist interpretation of the first claim, uncommitted to content conceptualism, and then I show how it can be reconciled with the second claim. Finally, I explain how perception holds rational relationships with our empirical thought through the exercise of observational concepts. These concepts link what I propose to call 'space of actions' to the logical space of reasons. (shrink)

In recent years, a central debate in the philosophy of mind and cognitive science concerns the role of the body in perception and cognition. For many contemporary philosophers, not only cognition but also perception is connected mainly with the brain, where the processing of input from the senses takes place; whereas for the proponents of ‘embodied cognition’ other aspects of the body beyond the brain, including the environment, play a constitutive role in cognitive processes. In terms of perception, a new (...) theory has emerged which stresses perception’s active character and claims that the embodied subject and the environment, with which it interacts, form a dynamic system. Supporters of ‘enactive perception’ such as Susan Hurley and Alva Noë maintain that the physical substrate or the supervenience basis of perceptual experience and phenomenal consciousness may include besides the brain and the nervous system other bodily and environmental features. Yet, it will be argued in this paper that the interaction between the subject and the environment forms a system of causal relations, so we can theoretically interfere in the causal chains and create hallucinations, which cannot be distinguished from veridical perception, or a virtual reality as in the film Matrix (1999). This kind of argument and its related thought experiments aim to stress the primacy of the brain in determining phenomenal states, and show that the body and certain interactions with the environment have a causal, but not a constitutive or essential role, in forming phenomenal consciousness.

In recent discussions of two important issues in the philosophy of perception, viz. the problems of perceptual presence and perceptual constancy, Merleau-Ponty’s ideas have been garnering attention thanks to the work of Sean Kelly and Alva Noë. Although both Kelly’s normative approach and Noë’s enactive approach highlight important aspects of Merleau-Ponty’s view, I argue that neither does full justice to it because they overlook the central role that style plays in his solution to these problems. I show that a (...) closer look at the Phenomenology and several other texts from this period reveals that, on Merleau-Ponty’s account, we are able to perceive the absent features of objects as present, constant properties, and constant objects because we recognize that the objects we perceive have a unique style that persists through and unifies all their appearances.

Some philosophers—for example, Husserl, Alva Noë and Susanna Siegel—have claimed that the contents of visual sensations standardly include references to the later visual episodes that one would have under certain conditions. The current paper claims that there are no good reasons for accepting that view. Instead, it is argued that the conscious phenomena which have been cited as manifesting the presence within visual contents of references to ways that things would look in the course of later visual sensations are (...) better explained in another manner: in terms of references within the contents of ordinary visual sensations to ways that things actually then look from various perspectives.

Justin Fisher (2007) has presented a novel argument designed to prove that all forms of mental internalism are false. I aim to show that the argument fails with regard to internalism about phenomenal experiences. The argument tacitly assumes a certain view about the ontology of phenomenal experience, which (inspired by Alva Noe) I call the “snapshot conception of phenomenal experience.” After clarifying what the snapshot conception involves, I present Fisher with a dilemma. If he rejects the snapshot conception, then (...) his argument against phenomenal internalism collapses. But if he embraces the snapshot conception, then internalists may argue that in light of the snapshot conception, their view is not so implausible—and that if Fisher still disagrees, he owes us an argument that shows why phenomenal internalism is false even given the snapshot conception. I conclude the paper by showing that Fisher cannot escape my criticism by adjusting his argument so that it no longer depends on the snapshot conception. (shrink)

Vehicle externalists hold that the physical substrate of mental states can sometimes extend beyond the brain into the body and environment. In a particular variation on vehicle externalism, Susan Hurley (1998) and Alva Noë (2004) have argued that perceptual states, states with phenomenal qualities, are among the mental states that can sometimes spread beyond the brain. Their vehicle externalism about perceptual states will be the main topic of this article. In particular, I will address three strong objections to their (...) vehicle externalism, objections by Ned Block (2005), Jesse Prinz (2006), and Fred Adams & Ken Aizawa (2008). Though in some ways these objections appear disparate, I will argue that all of them depend on a crucial presupposition, one which Hurley, Noë, and their sympathizers should reject. This presupposition is that perceptual character is fixed by an instantaneous snapshot of neural states, a view that Hurley dubbed ‘temporal atomism.’ To put the presupposition in more familiar terms, all three objections are implicitly committed to something like Dennett’s Cartesian Theater (1991). -/- In the first part of the article, I will discuss Hurley and Noë’s views, and include reasons why their views entail the rejection of the Cartesian Theater. In the next part of the article I will introduce the three objections and show how they presuppose something like a Cartesian Theater. I will also show that, if the Cartesian Theater is rejected, the objections all vanish. In the final part of the article I address the charge that Noë and Hurley confuse causation with constitution. This charge reveals a lack of appreciation for the way in which dynamical explanation motivates Hurley’s externalism. (shrink)

Pylyshyn restricts cognitively penetrable vision to late vision, whereas he does not make any distinction between different kinds of penetrating cognition. I argue that this approach disconnects early vision content from late vision content and blurs the distinction between the latter and the content of thought. To overcome this problem I suggest that we should not distinguish between different kinds of visual content but instead introduce a restriction on the kind of cognition that can directly penetrate visual experience. In particular, (...) I suggest that visual experience, unlike thought, is directly penetrated only by practical non-propositional knowledge. I specify this weak cognitive penetrability in anti-representational terms. In particular, I suggest that the dependence of visual content on practical non-propositional knowledge should be conceived as a rational non-inferential relation, for it is in this way that we can account for the distinctive content of visual experience.

In this paper, we argue that several recent ‘wide’ perspectives on cognition (embodied, embedded, extended, enactive, and distributed) are only partially relevant to the study of cognition. While these wide accounts override traditional methodological individualism, the study of cognition has already progressed beyond these proposed perspectives towards building integrated explanations of the mechanisms involved, including not only internal submechanisms but also interactions with others, groups, cognitive artifacts, and their environment. The claim is substantiated with reference to recent developments in the (...) study of “mindreading” and debates on emotions. We claim that the current practice in cognitive (neuro)science has undergone, in effect, a silent mechanistic revolution, and has turned from initial binary oppositions and abstract proposals towards the integration of wide perspectives with the rest of the cognitive (neuro)sciences.

I defend the widely-held view that morally worthy action need not be motivated by a desire to promote rightness as such. Some have recently come to reject this view, arguing that desires for rightness as such are necessary for avoiding a certain kind of luck thought incompatible with morally worthy action. I show that those who defend desires for rightness as such on the basis of this argument misunderstand the relationship between moral worth and the kind of luck that their (...) argument employs. Consequently, the argument provides no reason to doubt the popular view that a desire for rightness as such is no part of virtue. I conclude by suggesting that a family of worries about merely accidentally right action presuppose one side of the recent debate about objectivism and perspectivism about moral rightness. (shrink)

We demonstrate how real progress can be made in the debate surrounding the enhanced indispensability argument. Drawing on a counterfactual theory of explanation, well-motivated independently of the debate, we provide a novel analysis of ‘explanatory generality’ and how mathematics is involved in its procurement. On our analysis, mathematics’ sole explanatory contribution to the procurement of explanatory generality is to make counterfactual information about physical dependencies easier to grasp and reason with for creatures like us. This gives precise content to key (...) intuitions traded in the debate, regarding mathematics’ procurement of explanatory generality, and adjudicates unambiguously in favour of the nominalist, at least as far as explanatory generality is concerned.

The concept of moral wrongness, many think, has a distinctive kind of referential stability, brought out by moral twin earth cases. This article offers a new account of the source of this stability, deriving it from a metaphysics of content: “substantive” radical interpretation, and first-order normative assumptions. This story is distinguished from extant “reference magnetic” explanations of the phenomenon, and objections and replies are considered.

Alongside existing research into the social, political and economic impacts of the Web, there is a need to study the Web from a cognitive and epistemic perspective. This is particularly so as new and emerging technologies alter the nature of our interactive engagements with the Web, transforming the extent to which our thoughts and actions are shaped by the online environment. Situated and ecological approaches to cognition are relevant to understanding the cognitive significance of the Web because of the emphasis (...) they place on forces and factors that reside at the level of agent–world interactions. In particular, by adopting a situated or ecological approach to cognition, we are able to assess the significance of the Web from the perspective of research into embodied, extended, embedded, social and collective cognition. The results of this analysis help to reshape the interdisciplinary configuration of Web Science, expanding its theoretical and empirical remit to include the disciplines of both cognitive science and the philosophy of mind.

The view that it is better for life to be created free of disability is pervasive in both common sense and philosophy. We cast doubt on this view by focusing on an influential line of thinking that manifests it. That thinking begins with a widely-discussed principle, Procreative Beneficence, and draws conclusions about parental choice and disability. After reconstructing two versions of this argument, we critique the first by exploring the relationship between different understandings of well-being and disability, and the second (...) by more briefly focusing on the idea of a significant reason. By placing these results against the broader historical and ongoing contexts in which the lives of those with disabilities have been deemed of inferior quality, we conclude with a call for greater humility about disability and well-being in thought and practice.

In this Introduction we introduce the central themes of the Evaluative Perception volume. After identifying historical and recent contemporary work on this topic, we discuss some central questions under three headings: (1) Questions about the Existence and Nature of Evaluative Perception: Are there perceptual experiences of values? If so, what is their nature? Are experiences of values sui generis? Are values necessary for certain kinds of experience? (2) Questions about the Epistemology of Evaluative Perception: Can evaluative experiences ever justify evaluative (...) judgments? Are experiences of values necessary for certain kinds of justified evaluative judgments? (3) Questions about Value Theory and Evaluative Perception: Is the existence of evaluative experience supported or undermined by particular views in value theory? Are particular views in value theory supported or undermined by the existence of value experience? (shrink)

Sometimes it is indeterminate what an agent morally ought do. This generates a Decision Ought Challenge—to give moral guidance to agents in such a scenario. This article is a field guide to the options for a theory of the decision ought for cases of indeterminacy. Three categories of view are evaluated, and the best representative for each is identified.

Many accounts of structural rationality give a special role to logic. This paper reviews the problem case of clear-eyed logical uncertainty. An account of rational norms on belief that does not give a special role to logic is developed: doxastic probabilism.

Throughout his career, Derek Parfit made the bold suggestion, at various times under the heading of the "Normativity Objection," that anyone in possession of normative concepts is in a position to know, on the basis of their competence with such concepts alone, that reductive realism in ethics is not even possible. Despite the prominent role that the Normativity Objection plays in Parfit's non-reductive account of the nature of normativity, when the objection hasn't been ignored, it's been criticized and even derided. (...) We argue that the exclusively negative attention that the objection has received has been a mistake. On our reading, Parfit's Normativity Objection poses a serious threat to reductivism, as it exposes the uneasy relationship between our a priori knowledge of a range of distinctly normative truths and the typical package of semantic commitments that reductivists have embraced since the Kripkean revolution.

In large, impersonal moral orders many of us wish to maintain good will toward our fellow citizens only if we are reasonably sure they will maintain good will toward us. The mutual maintaining of good will, then, requires that we somehow communicate our intentions to one another. But how do we actually do this? The current paper argues that when we engage in moral responsibility practices—that is, when we express our reactive attitudes by blaming, praising, and resenting—we communicate a desire (...) to maintain good will to those in the community we are imbedded in. Participating in such practices alone will not get the job done, though, for expressions of our reactive attitudes are often what economists call cheap talk. But when we praise and blame in cases of moral diversity, expressions of our reactive attitudes act as costly signals capable of solving our social dilemma. (shrink)

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

In his commentary on Aristotle’s Physics, Nicole Oresme raises a question that he is apparently the first to ask in these terms, in such a context: do all beings have the desire to persevere into being? Before him, this question is not found in any of the medieval commentaries on Aristotle’s Physics. But after him it became canonical until at least the 16th century, since it can be found in Pietro Pomponazzi’s works for example. The novelty here consists in questioning (...) the validity of Averroes’ thesis, in his own commentary on the Physics, according to which all beings have the desire to persist into being, using the Augustinian analysis of voluntary death and suicide. How can we explain that one can freely put an end to his days if he is naturally inclined by a desire for life and even for eternity? Oresme’s solution consists in justifying not only the possibility, but also the moral obligation to accept death under certain conditions. In most cases, we do not really want to die. The desperate man wishes to cancel his misfortune and the heroic man who sacrifices himself for his country wishes to immortalize himself in the memory of other men. From a moral point of view, Nicole Oresme justifies only one case of voluntary death: that of individual sacrifice for the common good. The aim of this paper is to analyze precisely this important turning point in the long history of the notion of conatus in the West by comparing this quaestio from the commentary on the Physics with the glosses that accompany the French translation of the Nicomachean Ethics realised by Oresme at the court of Charles V.

Competitive negotiators frequently use tactics which others view as "unethical", in that these tactics either violate standards of truth telling or violate the perceived rules of negotiation. This paper sought to determine how business students viewed a number of marginally ethical negotiating tactics, and to determine the underlying factor structure of these tactics. The factor analysis of these tactics revealed five clear factors which were highly similar across the two samples, and which parallel (to a moderate degree) categories of tactics (...) proposed by earlier theory. Data from one sample also permitted comparisons of the appropriateness of certain tactics across gender, nationality, ethnic origin and perception of one's negotiating style. (shrink)

Artificial intelligence (AI) systems have demonstrated impressive performance across a variety of clinical tasks. However, notoriously, sometimes these systems are 'black boxes'. The initial response in the literature was a demand for 'explainable AI'. However, recently, several authors have suggested that making AI more explainable or 'interpretable' is likely to be at the cost of the accuracy of these systems and that prioritising interpretability in medical AI may constitute a 'lethal prejudice'. In this paper, we defend the value of interpretability (...) in the context of the use of AI in medicine. Clinicians may prefer interpretable systems over more accurate black boxes, which in turn is sufficient to give designers of AI reason to prefer more interpretable systems in order to ensure that AI is adopted and its benefits realised. Moreover, clinicians may be justified in this preference. Achieving the downstream benefits from AI is critically dependent on how the outputs of these systems are interpreted by physicians and patients. A preference for the use of highly accurate black box AI systems, over less accurate but more interpretable systems , may itself constitute a form of lethal prejudice that may diminish the benefits of AI to - and perhaps even harm - patients.

Seeking to preserve electronically encoded evidence implies that an incident or event has occurred requiring fact extrapolation for presentation, as proof of an irregularity or illegal act.

In this paper, we take a meta-theoretical stance and aim to compare and assess two conceptual frameworks that endeavor to explain phenomenal experience. In particular, we compare Feinberg & Mallatt’s Neurobiological Naturalism (NN) and Tononi’s and colleagues' Integrated Information Theory (IIT), given that the former pointed out some similarities between the two theories (Feinberg & Mallatt 2016c-d). To probe their similarity, we first give a general introduction to both frameworks. Next, we expound a ground plan for carrying out our analysis. (...) We move on to articulate a philosophical profile of NN and IIT, addressing their ontological commitments and epistemological foundations. Finally, we compare the two point-by-point, also discussing how they stand on the issue of artificial consciousness. (shrink)

The automation of online social life is an urgent issue for researchers and the public alike. However, one of the most significant uses of such technologies seems to have gone largely unnoticed by the research community: religion. Focusing on Islamic Prayer Apps, which automatically post prayers from its users’ accounts, we show that even one such service is already responsible for millions of tweets daily, constituting a significant portion of Arabic-language Twitter traffic. We argue that the fact that a phenomenon (...) of these proportions has gone unnoticed by researchers reveals an opportunity to broaden the scope of the current research agenda on online automation.

Objectives: Machine learning (ML) has the potential to facilitate “continual learning” in medicine, in which an ML system continues to evolve in response to exposure to new data over time, even after being deployed in a clinical setting. In this article, we provide a tutorial on the range of ethical issues raised by the use of such “adaptive” ML systems in medicine that have, thus far, been neglected in the literature. -/- Target audience: The target audiences for this tutorial are (...) the developers of ML AI systems, healthcare regulators, the broader medical informatics community, and practicing clinicians. -/- Scope: Discussions of adaptive ML systems to date have overlooked the distinction between 2 sorts of variance that such systems may exhibit—diachronic evolution (change over time) and synchronic variation (difference between cotemporaneous instantiations of the algorithm at different sites)—and underestimated the significance of the latter. We highlight the challenges that diachronic evolution and synchronic variation present for the quality of patient care, informed consent, and equity, and discuss the complex ethical trade-offs involved in the design of such systems.

This article offers a comprehensive and critical analysis of Eric Heinze’s book Hate Speech and Democratic Citizenship (Oxford University Press, 2016). Heinze’s project is to formulate and defend a more theoretically complex version of the idea (also defended by people like Ronald Dworkin and James Weinstein) that general legal prohibitions on hate speech in public discourse compromises the state’s democratic legitimacy. We offer a detailed synopsis of Heinze’s view, highlighting some of its distinctive qualities and strengths. We then develop a (...) critical response to this view with three main focal points: (1) the characterisation of democratic legitimacy as something distinct from (and whose demands aren’t identical with those of) legitimacy per se; (2) the claim that the requirements of democracy are hypothetical, rather than categorical, imperatives; and relatedly (3) the question of how we should reconcile the requirements of democratic legitimacy with the costs that may follow from prioritising democratic legitimacy. We argue that there are significant difficulties for Heinze’s account on all three fronts. (shrink)

In the De Anima, Aristotle claims that the five senses are infallible about their proper objects. I contend that this claim means that sight is infallible about its proper object in its most specific form, i. e. sight is infallible about red or green and not merely about color in general. This robust claim is justified by Aristotle’s teleological principle that nature does nothing in vain. Additionally, drawing on Aristotle’s comparison of perception and one’s understanding of the essences, I defend (...) a conception of the senses in which the structure of their contents is simple rather than predicative and show how this coheres better with the rest of my interpretation.

Philosophers have recently come to focus on explaining the phenomenon of ​bad beliefs,​ beliefs that are apparently true and well-evidenced but nevertheless objectionable. Despite this recent focus, a consensus is already forming around a particular explanation of these beliefs’ badness called ​moral encroachment​, according to which, roughly, the moral stakes engendered by bad beliefs make them particularly difficult to justify. This paper advances an alternative account not just of bad beliefs but of bad attitudes more generally according to which bad (...) beliefs’ badness originates not in a failure of sufficient evidence but in a failure to respond adequately to reasons. I motivate this alternative account through an analogy to recent discussions of moral worth centered on the well-known grocer case from Kant’s ​Groundwork​, and by showing that this analogy permits the proposed account to generalize to bad attitudes beyond belief. The paper concludes by contrasting the implications of moral encroachment and of the proposed account for bad attitudes’ blameworthiness. (shrink)

Worlds where things divide forever ("gunk" worlds) are apparently conceivable. The conceivability of such scenarios has been used as an argument against "nihilist" or "near-nihilist" answers to the special composition question.

For the greater part of the last 50 years, it has been common for philosophers of mind and cognitive scientists to invoke the notion of realization in discussing the relationship between the mind and the brain.

Artificial intelligence is sometimes described as the attempt either to model or to actually construct systems that realize some of the same psychological abilities that we and (...) other living creatures possess.

Existing metasemantic projects presuppose that word- (or sentence-) types are part of the non-semantic base. We propose a new strategy: an endogenous account of word types, that is, one where word types are fixed as part of the metasemantics. On this view, it is the conventions of truthfulness and trust that ground not only the meaning of the words (meaning by convention) but also what the word type is of each particular token utterance (words by convention). The same treatment extends (...) to identifying the populations through which the conventions prevail. We consider whether this proposal leads to new underdetermination challenges for metasemantics, and make a case that it does not. (shrink)

The VIA Classification of Strengths and Virtues is the most commonly used model of positive personality. In this study, we used two methods of model modification to develop models for two measures of the character strengths, the VIA Inventory of Strengths-Revised and the Global Assessment of Character Strengths. The first method consisted of freeing residual covariances based on modification indices until good fit was achieved. The second was residual network modeling (RNM), which frees residual partial correlations while minimizing a function (...) that penalizes more complex models. Models based on both strategies were developed for the two questionnaires. The resulting structural models were then applied to four other samples. Though both modification procedures achieved good fit in the sample used to develop the models, only RNM resulted in adequate model fit for both measures in all cross-validation samples. This finding suggests RNM is more robust against overfitting than traditional practices. Moreover, the result supports the validity of the three-factor model of character strengths with replicability. (shrink)

Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM trials. (...) Using Allen Buchanan & Robert Keohane's model of global political legitimacy, we examine several existing global institutions as possible analogues for a politically legitimate SRM decision-making body.
