Next SectionAccess to medicines, vaccination and care in resource-poor settings is threatened by the emigration of physicians and other health workers. In entire regions of the developing world, low physician density exacerbates child and maternal mortality and hinders treatment of HIV/AIDS. This article invites philosophers to help identify ethical and effective responses to medical brain drain. It reviews existing proposals and their limitations. It makes a case that, in resource-poor countries, ’locally relevant medical training’—teaching primarily locally endemic diseases and practice (...) in scarcity conditions, training in rural communities and admitting rural students preferentially—could help improve retention. Locally relevant training would arguably diminish medical brain drain in five ways. It would (i) make graduates less attractive for Western employers, (ii) align graduates’ expectations with actual practice, diminishing ‘burn-out’, (iii) enhance the professional prestige of local practice, (iv) hold rotations in, and recruit applicants from, rural areas, which is known to improve retention there, and (v) create local career development options that attract practitioners to stay. Such educational reform may raise worries about poor-quality care, breach of the freedom of education and occupation, breach of the freedom of movement, unequal distribution of opportunities among students, hypocrisy and resistance from influential actors. We address these worries. (shrink)

This study explores academic dishonesty within higher education, with a particular focus on the perspectives of the Arab ethnic community in Israel. Through in-depth interviews involving 38 students, the research unveils three overarching themes: (a) “Academic dishonesty as a social norm” illuminates the prevalent acceptance of cheating driven by moral justifications, emphasizing the crucial role of perceived low likelihood of detection and inconsistencies in enforcing academic standards in a multicultural context, (b) “Rationalizations for academic dishonesty and coping with minority status,” (...) explores how overwhelming academic demands, familial and social pressures, and collaborative support networks contribute to unethical behavior, and (c) “Erosion of academic effort,” elucidates the connection between uninspiring teaching methods and the derision of less committed peers, contributing to plagiarism. These findings contribute to a culturally understanding of academic dishonesty. Practically, recognizing specific groups’ challenges with academic dishonesty can inform instructors and administrators, aiding effective strategies to promote integrity. (shrink)

Bioscientists generate far more data than their minds can handle, and this trend is likely to continue. With the aid of a small set of versatile tools for mathematical modeling and statistical assessment, bioscientists can explore their real-world systems without experiencing data overflow. This article outlines an approach for combining modern high-throughput, low-cost, but non-selective biospectroscopy measurements with soft, multivariate biochemometrics data modeling to overview complex systems, test hypotheses, and making new discoveries. From preliminary, broad hypotheses and goals, many relevant (...) samples are selected and measured with respect to many informative variables. The resulting tables represent a “cacophony” of data. From these, the most relevant and reliable “underlying harmonies and rhythms” are extracted and tested statistically, displayed for interpretation, and used for prediction. Outliers are detected automatically. Interesting subsets of samples can then be chosen for in-depth analyses in subsequent research cycles. This pragmatic, top-down approach takes advantage of developments in both “soft,” data-driven modeling and “hard,” knowledge-driven cultures. Data analytical examples show how information-rich biospectroscopy can be used for characterizing and quantifying known and unknown chemical constituents and physical phenomena in intact biosamples. This is based on a combination of deductive “hard” and inductive “soft” modeling. The examples represent NIR spectra of biochemical mixtures, FTIR spectra of a microbiological fermentation process, and FTIR analysis of fatty acids in milk for functional genomics. (shrink)

Both left libertarians, who support the redistribution of income and wealth through taxation, and right libertarians, who oppose redistributive taxation, share an important view: that, looming catastrophes aside, the state must never redistribute any part of our body or our person without our consent. Cécile Fabre rejects that view. For her, just as the undeservedly poor have a just claim to money from their fellow citizens in order to lead a minimally flourishing life, the undeservedly ‘medically poor’ have a just (...) claim to help from fellow citizens in order to lead such a life. Such obligatory help may in principle involve even the supply of body parts for transplantation. The state ought to exact such resources from the medically rich whenever doing so would secure the prospect of a minimally flourishing life to the medically poor without denying that prospect to anyone else. Fabre criticizes Ronald Dworkin's belief in ‘a prophylactic line that comes close to making the body inviolate, that is, making body parts not parts of social resources at all’. For her, ‘Duties to help. . . do not stop at material resources: they involve the body. . . in invasive ways’. (shrink)

Which inequalities in longevity and health among individuals, groups, and nations are unfair? And what priority should health policy attach to narrowing them? These essays by philosophers, economists, epidemiologists, and physicians attempt to determine how health inequalities should be conceptualized, measured, ranked, and evaluated.

Brain implants, such as Deep Brain Stimulation (DBS), which are designed to improve motor, mood and behavioural pathology, present unique challenges to our understanding of identity, agency and free will. This is because these devices can have visible effects on persons' physical and psychological properties yet are essentially undetectable when operating correctly. They can supplement and compensate for one's inherent abilities and faculties when they are compromised by neuropsychiatric disorders. Further, unlike talk therapy or pharmacological treatments, patients need not ‘do’ (...) anything for the treatment to take effect. If one accepts, as we argue here, that brain implants are unique among implantable types of devices, then this can have significant implications for what it means to persist as the same person and be the source of one's thoughts and actions. By examining two of the most common indications for DBS in current use, namely in the motor (Parkinson's Disease) and psychiatric (Major Depression) domains, we further argue that although DBS, as it is currently applied, does not necessarily represent a unique threat to personal identity and agency per se, it introduces an unprecedented ‘third party’ into the debate on these concepts. In this way, DBS can be used as a tool to begin probing, both conceptually and empirically, some of philosophy's most perennial metaphysical questions. (shrink)

Dreams are a remarkable experiment in psychology and neuroscience, conducted every night in every sleeping person. They show that the human brain, disconnected from the environment, can generate an entire world of conscious experiences by itself. Content analysis and developmental studies have promoted understanding of dream phenomenology. In parallel, brain lesion studies, functional imaging and neurophysiology have advanced current knowledge of the neural basis of dreaming. It is now possible to start integrating these two strands of research to address fundamental (...) questions that dreams pose for cognitive neuroscience: how conscious experiences in sleep relate to underlying brain activity; why the dreamer is largely disconnected from the environment; and whether dreaming is more closely related to mental imagery or to perception.

This article argues that, in its standard formulation, luck-egalitarianism is false. In particular, I show that disadvantages that result from perfectly free choice can constitute egalitarian injustice. I also propose a modified formulation of luck-egalitarianism that would withstand my criticism. One merit of the modification is that it helps us to reconcile widespread intuitions about distributive justice with equally widespread intuitions about punitive justice.

There are many different notions of information in logic, epistemology, psychology, biology and cognitive science, which are employed differently in each discipline, often with little overlap. Since our interest here is in biological processes and organisms, we develop a taxonomy of functional information that extends the standard cue/signal distinction (in animal communication theory). Three general, main claims are advanced here. (1) This new taxonomy can be useful in describing learning and communication. (2) It avoids some problems that the natural/non-natural information (...) distinction faces. (3) Functional information is​ ​produced through exploration and stabilisation processes. (shrink)

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)

This paper deals with the question: how is computation best individuated? -/- 1. The semantic view of computation: computation is best individuated by its semantic properties. 2. The causal view of computation: computation is best individuated by its causal properties. 3. The functional view of computation: computation is best individuated by its functional properties. -/- Some scientific theories explain the capacities of brains by appealing to computations that they supposedly perform. The reason for that is usually that computation is individuated (...) semantically. I criticize the reasons in support of this view and its presupposition of representation and semantics. Furthermore, I argue that the only justified appeal to a representational individuation of computation might be that it is partly individuated by implicit intrinsic representations. (shrink)

Growing interest in psychiatric neurosurgery, and in deep brain stimulation (DBS) in particular, requires that the field be placed in the appropriate historical and scientific context. Current methods of neuromodulation for refractory psychiatric conditions are premised on assumptions similar to those proposed in earlier attempts, namely, the number of resistant patients and the absence of any other effective treatments. As a result, a discussion of the current and future prospects, as well as the limits, of neuromodulation is required to avoid (...) a replay of earlier transgressions, and to place its current chapter in the appropriate historical and ethical context.

The article begins by reconstructing the just distribution of the social bases of self-respect, a principle of justice that is covert in Rawls’s writing. I argue that, for Rawls, justice mandates that each social basis for self-respect be equalized. Curiously, for Rawls, that principle ranks higher than Rawls’s two more famous principles of justice - equal liberty and the difference principle. I then recall Rawls’s well-known confusion between self-respect and another form of self-appraisal, namely, confidence in one’s determinate plans and (...) capacities. Correcting that confusion forces Rawls to accept objectionable and illiberal politics. Surprisingly, a consistent Rawls must endorse absolute economic equality, deny liberty any priority whatsoever, or sponsor still other illiberal political views - evidence of a flaw in the ethical basis of Rawls’s politics.

Recent developments in the field of neurosurgery, specifically those dealing with the modification of mood and affect as part of psychiatric disease, have led some researchers to discuss the ethical implications of surgery to alter personality and personal identity. As knowledge and technology advance, discussions of surgery to alter undesirable traits, or possibly the enhancement of normal traits, will play an increasingly larger role in the ethical literature. So far, identity and enhancement have yet to be explored in a neurosurgical (...) context, despite the fact that 1) neurological disease and treatment both potentially alter identity, and 2) that neurosurgeons will likely be the purveyors of future enhancement implantable technology. Here, we use interviews with neurosurgical patients to shed light on the ethical issues and challenges that surround identity and enhancement in neurosurgery. The results provide insight into how patients approach their identity prior to potentially identity-altering procedures and what future ethical challenges lay ahead for clinicians and researchers in the field of neurotherapeutics.

Increasingly, bioethicists defend informed consent as a safeguard for trust in caretakers and medical institutions. This paper discusses an ‘ideal type’ of that move. What I call the trust-promotion argument for informed consent states:1. Social trust, especially trust in caretakers and medical institutions, is necessary so that, for example, people seek medical advice, comply with it, and participate in medical research.2. Therefore, it is usually wrong to jeopardise that trust.3. Coercion, deception, manipulation and other violations of standard informed consent requirements (...) seriously jeopardise that trust.4. Thus, standard informed consent requirements are justified.This article describes the initial promise of this argument, then identifies challenges to it. As I show, the value of trust fails to account for some commonsense intuitions about informed consent. We should revise the argument, commonsense morality, or both. (shrink)

Notwithstanding the success of conventional field trials for vaccines against COVID-19, human challenge trials that could obtain more information about these and about other vaccines and further strategies against it are about to start in the UK. One critique of COVID-19 HCTs is their distinct paucity of information on crucial population groups. For safety reasons, these HCTs will exclude candidate participants of advanced age or with comorbidities that worsen COVID-19, yet a vaccine should protect such populations. We turn this cliché (...) on its head. The truth is that either an HCT or a field trial has intrinsic generalisability limitations, that an HCT can expedite protection of high-risk participants even without challenging them with the virus, and that an important route to obtaining results generalisable to high-risk groups under either strategy is facilitated by HCTs. There are no data in this work. (shrink)

Often, a health resource distribution (or, more generally, a health policy) ranks higher than another on one value, say, on promoting total population health; and lower on another, say, on promoting that of the worst off. Then, some opine, there need not be a rational determination as to which of the multiple distributions that partially fulfill both one ought to choose. Sometimes, reason determines only partially, intransitively, or contentiously which of the many “compromises” between these two values is best or (...) most choiceworthy. Norman Daniels, Ruth Chang, Martijn Boot, and Anders Herlitz affirm this opinion, which I shall call “value incommensurability,” “rational underdeterminacy,” or “reasonable disagreement.” To decide between the multiple reasonable compromises on health resource distribution, these philosophers recommend a deliberative democratic process, on two main grounds. First, in such situations, deliberation can produce the determinacy needed for decisionmaking. Second, by treating respectfully and justly even those patients or communities for whom the distributive compromise selected is bad, deliberation shields the legitimacy of that policy. Increasingly, practically-oriented bioethics recommends democratic deliberation even more expansively than these philosophers do—for nearly every decision on health resource distribution and not only when values are incommensurate—on these two grounds and on others. And one could propose a more modest variant on this expansive move as the justification of democratic deliberation. I argue that none of these moves warrants democratic deliberation on health policy.

The target article focuses on how attacker-defender conflicts are fought. This commentary complements it by considering how attacker-defender conflicts may be resolved at the bargaining table.

BackgroundMeasuring the outcomes of palliative care plays an important role to improve the quality, efficiency, and availability of these services in patients with cancer. Using valid, reliable, and culturally appropriate tools has a considerable role to measure these outcomes. This study aimed to assess the psychometric properties of the translated version of the Palliative care Outcome Scale.MethodsThis methodological study was conducted in two outpatient clinics related to Shohada Tajrish and Baqiyatallah hospitals in Tehran in 2019–2020. The translation was done using (...) the Forward-Backward approach after gaining permission from the developer. Face validity was tested with 10 patients with cancer through cognitive interviewing, as well as content validity with four experts. Construct validity was performed by exploratory factor analysis and confirmation. To assess the reliability, internal consistency was assessed by using Cronbach's alpha coefficient, and relative stability was assessed using the interclass correlation coefficient. Furthermore, interpretability and ceiling and floor effects were assessed.ResultsA total of 353 patients with cancer under palliative care were included in the study. Then, three psychological, physical, and social factors with a cumulative variance of 54.34% were extracted in exploratory factor analysis. Confirmatory factor analysis showed that the model has a good fit of information. Cronbach's alpha coefficient for scale was 0.719. Furthermore, the ICC was 0.812. The scale was interpretable, and ceiling and floor effects were 0%.ConclusionPersian version of the POS was evaluated as a valid and reliable tool. Therefore, it can be used by the clinician to monitor the consequences of palliative care in Iranian cancer patients. (shrink)

Wittgenstein’s Tractatus construes the nature of reasoning in a manner which sharply conflicts with the conventional wisdom that logic is normative, not descriptive of thought. For although we sometimes seem to reason incorrectly, Wittgenstein denies that we can make logical mistakes (5.473). My aim in this paper is to show that the Tractatus provides us with good reasons to rethink some of the central assumptions that are standardly made in thinking about the relation between logic and thought. In particular, the (...) rejection of logical mistakes is to be understood in connection with Wittgenstein’s non-psychological approach to the thinking subject (5.641). On Wittgenstein's view, inference, understanding, and meaning are holistically related; cases of defective reasoning are to be explained in terms of a defective grasp of meaning which manifests in an indeterminate use of signs. Invalid reasoning therefore does not count for Wittgenstein as a species of reasoning, but rather as the mere illusion of reasoning. The rejection of logical mistakes thus gives voice to a radical disjunctivist approach. (shrink)

This paper deals with the question: What are the criteria that an adequate theory of computation has to meet? 1. Smith's answer: it has to meet the empirical criterion (i.e. doing justice to computational practice), the conceptual criterion (i.e. explaining all the underlying concepts) and the cognitive criterion (i.e. providing solid grounds for computationalism). 2. Piccinini's answer: it has to meet the objectivity criterion (i.e. identifying computation as a matter of fact), the explanation criterion (i.e. explaining the computer's behaviour), the (...) right things compute criterion, the miscomputation criterion (i.e. accounting for malfunctions), the taxonomy criterion (i.e. distinguishing between different classes of computers) and the empirical criterion. 3. Von Neumann's answer: it has to meet the precision and reliability of computers criterion, the single error criterion (i.e. addressing the impacts of errors) and the distinction between analogue and digital computers criterion. 4. “Everything” computes answer: it has to meet the implementation theory criterion by properly explaining the notion of implementation. -/- According to computationalists, minds are computational. Before we can judge the plausibility of any particular computationalist theory, we need to understand what notion of computation this theory employs. Although there are extant accounts of computation, any of which may, in principle, serve as a basis for computationalism, it isn’t clear that they’re all equivalent or even adequate as accounts of computation proper. By examining plausible alternatives to Smith’s adequacy criteria, our goal here is to resist his claim that no adequate account of computation proper is possible. (shrink)

This article analyses and interprets the works of Friedensreich Hundertwasser (1928–2000) as a source of inspiration for environmental ethics and offers an extended model of the Ecological Self based on an interpretation of his works. Hundertwasser was a prominent Jewish-Austrian artist and environmental activist, yet despite his commitment to environmental issues, he has not received the attention he deserves from the environmental ethics community. His works and writings suggest a critique and reformulation of the well-known concept of the Ecological Self. (...) This concept implies that humans are essentially embedded in the natural world – that the Self is porous and open rather than disengaged and atomistic. This article suggests an alternative, holistic and extended version of this concept. It assesses and incorporates additional layers found between humans and nature – clothing, architecture, urban environments, and social and political environments. (shrink)

The question ‘What is computation?’ might seem a trivial one to many, but this is far from being in consensus in philosophy of mind, cognitive science and even in physics. The lack of consensus leads to some interesting, yet contentious, claims, such as that cognition or even the universe is computational. Some have argued, though, that computation is a subjective phenomenon: whether or not a physical system is computational, and if so, which computation it performs, is entirely a matter of (...) an observer choosing to view it as such. According to one view, which we dub bold anti-realist pancomputationalism, every physical object (can be said to) computes every computer program. According to another, more modest view, some computational systems can be ascribed multiple computational descriptions. We argue that the first view is misguided, and that the second view need not entail observer-relativity of computation. At least to a large extent, computation is an objective phenomenon. Construed as a form of information processing, we argue that information-processing considerations determine what type of computation takes place in physical systems. (shrink)

Floridi’s Theory of Strongly Semantic Information posits the Veridicality Thesis. One motivation is that it can serve as a foundation for information-based epistemology being an alternative to the tripartite theory of knowledge. However, the Veridicality thesis is false, if ‘information’ is to play an explanatory role in human cognition. Another motivation is avoiding the so-called Bar-Hillel/Carnap paradox. But this paradox only seems paradoxical, if ‘information’ and ‘informativeness’ are synonymous, logic is a theory of inference, or validity suffices for rational inference; (...) a, b, and c are false.

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.

This essay responds to criticisms of and reflections on A Theory of Truces offered by Keith Breen, David Lyons, Colleen Murphy and Thaddeus Metz. I focus on the place of truces within just war theory, the permissibility of making truces with particularly unsavory actors, the tension between present and future considerations in truce making, and Truce Thinking as an instance of non-ideal theory.

It is common in cognitive science to equate computation (and in particular digital computation) with information processing. Yet, it is hard to find a comprehensive explicit account of concrete digital computation in information processing terms. An information processing account seems like a natural candidate to explain digital computation. But when ‘information’ comes under scrutiny, this account becomes a less obvious candidate. Four interpretations of information are examined here as the basis for an information processing account of digital computation, namely Shannon (...) information, algorithmic information, factual information and instructional information. I argue that any plausible account of concrete computation has to be capable of explaining at least the three key algorithmic notions of input, output and procedures. Whist algorithmic information fares better than Shannon information, the most plausible candidate for an information processing account is instructional information. (shrink)

Which notion of computation (if any) is essential for explaining cognition? Five answers to this question are discussed in the paper. (1) The classicist answer: symbolic (digital) computation is required for explaining cognition; (2) The broad digital computationalist answer: digital computation broadly construed is required for explaining cognition; (3) The connectionist answer: sub-symbolic computation is required for explaining cognition; (4) The computational neuroscientist answer: neural computation (that, strictly, is neither digital nor analogue) is required for explaining cognition; (5) The extreme (...) dynamicist answer: computation is not required for explaining cognition. The first four answers are only accurate to a first approximation. But the “devil” is in the details. The last answer cashes in on the parenthetical “if any” in the question above. The classicist argues that cognition is symbolic computation. But digital computationalism need not be equated with classicism. Indeed, computationalism can, in principle, range from digital (and analogue) computationalism through (the weaker thesis of) generic computationalism to (the even weaker thesis of) digital (or analogue) pancomputationalism. Connectionism, which has traditionally been criticised by classicists for being non-computational, can be plausibly construed as being either analogue or digital computationalism (depending on the type of connectionist networks used). Computational neuroscience invokes the notion of neural computation that may (possibly) be interpreted as a sui generis type of computation. The extreme dynamicist argues that the time has come for a post-computational cognitive science. This paper is an attempt to shed some light on this debate by examining various conceptions and misconceptions of (particularly digital) computation. (shrink)

In political philosophy and in economics, unfair inequality is usually assessed between individuals, nowadays often on luck-egalitarian grounds. You have more than I do and that's unfair. By contrast, in epidemiology and sociology, unfair inequality is traditionally assessed between groups. More is concentrated among people of your class or race than among people of mine, and that's unfair. I shall call this difference the egalitarian ‘divorce’. Epidemiologists, and their ‘divorce lawyers’ Paula Braveman, Norman Daniels, and Iris Marion Young, explain that (...) not every inequality between individuals is an inequity. Only inequality between social status groups is unfair. Only such inequality stems from problems like partiality, discrimination, oppression, inequality-related population health problems, and unfair distribution of prospects. And it alone is actionable. By contrast, inequality between individuals, e.g. in longevity, is natural, inevitable, less important, or otherwise less informative — not unjust. In ‘divorce trial’ mode, I respond to epidemiologists that group inequalities lack the intrinsic disvalue that they ascribe them. They may be instrumentally or contingently bad or wrong, not essentially so. I then shift to ‘remarriage’: although group inequalities lack intrinsic badness or wrongness, for multiple reasons they remain useful to measure. (shrink)

In many countries worldwide, especially in Sub-Saharan Africa, a shortage of physicians limits the provision of lifesaving interventions. One existing strategy to increase the number of physicians in areas of critical shortage is conditioning medical school scholarships on a precommitment to work in medically underserved areas later. Current practice is usually to demand only one year of service for each year of funded studies. We show the effectiveness of scholarships conditional on such precommitment for increasing physician supplies in underserved areas. (...) Then we defend these scholarships against ethical worries that they constitute slavery contracts; rely on involuntary, biased, or unauthorized early consent by a young signatory; put excessive strains on signed commitments; give rise to domination; and raise suspicion of slavery contracts. Importantly, we find that scholarships involving far longer commitment than current practice allows would also withstand these worries. Policymakers should consider introducing conditional scholarships, including long-term versions, as a means to increasing the supply of physicians to medically underserved areas. (shrink)

A single physical process may often be described equally well as computing several different mathematical functions—none of which is explanatorily privileged. How, then, should the computational identity of a physical system be determined? Some computational mechanists hold that computation is individuated only by either narrow physical or functional properties. Even if some individuative role is attributed to environmental factors, it is rather limited. The computational semanticist holds that computation is individuated, at least in part, by semantic properties. She claims that (...) the mechanistic account lacks the resources to individuate the computations performed by some systems, thereby leaving interesting cases of computational indeterminacy unaddressed. This article examines some of these views, and claims that more cases of computational indeterminacy can be addressed, if the system-environment interaction plays a greater role in individuating computations. A new, long-arm functional strategy for individuating computation is advanced. (shrink)

Cities are traditionally characterized as a sub-unit of the state that functions as a socioeconomic node. However, global trends in recent decades indicate that cities are gradually acquiring a semi-independent political role, challenging and contesting the nation state`s authority. Into the twenty-first century, cities` actions in global politics (e.g., supranational city-based networks) and within the state (e.g., sanctuary cities) indicate that they aspire to attain or even directly claim more political autonomy. However, achieving these localist goals sometimes warrants regional cooperation (...) with neighboring municipal jurisdictions, thereby engendering ad-hoc and bottom-up regionalisms. Addressing this phenomenon theoretically, this Article analyzes three empirically and conceptually distinct types of the localist-regionalist nexus, demonstrating different rationales: (1) regional cooperation supporting localist innovation independent of state intervention; (2) regional cooperation supporting localist contestation of state policies; and (3) regional solidarity in the face of national tensions. Based on recent examples from Israel, it analyzes these three types along with their political and normative implications. Despite various discrepancies and possible tensions between localism and regionalism, the main conclusion emerging from this Article is that these two principles are not mutually exclusive. Moreover, although there are legal, institutional, political, and ideological tensions between them, the analysis suggests a third way between localism or regionalism. Likewise, some types of regionalization may act as a mechanism or tactic to support and deepen localist agendas. (shrink)

By means of a reductio argument, Wittgenstein’s Tractatus calls into question the very idea that we can represent logical form. My paper addresses three interrelated questions: first, what conception of logical form is at issue in this argument? Second, whose conception of logic is this argument intended to undermine? And third, what could count as an adequate response to it? I show that the argument construes logical form as the universal, underlying correlation of any representation and the reality it represents. (...) I further show that the argument seeks to undermine core commitments of Frege’s and Russell’s. But the reductio, as I read it, is not intended to establish the falsity of any of their specific assumptions. Rather, its aim is to make manifest the indeterminacies that underlie the language in which these assumptions are framed, and establish the need for a transformation of that language. So understood, Wittgenstein’s argument exemplifies his idea that philosophy is not a theory, but an activity of elucidation. The interpretation I propose bears on one of the central debates in the literature, namely how we should understand Wittgenstein’s contention that his elucidations succeed despite being nonsensical.

A gradual semantics takes a weighted argumentation framework as input and outputs a final acceptability degree for each argument, with different semantics performing the computation in different manners. In this work, we consider the problem of attack inference. That is, given a gradual semantics, a set of arguments with associated initial weights, and the final desirable acceptability degrees associated with each argument, we seek to determine whether there is a set of attacks on those arguments such that we can obtain (...) these acceptability degrees. The main contribution of our work is to demonstrate that the associated decision problem, i.e., whether a set of attacks can exist which allows the final acceptability degrees to occur for given initial weights, is NP-complete for the weighted h-categoriser and card-based semantics, and is polynomial for the weighted max-based semantics, even for the complete version of the problem (where all initial weights and final acceptability degrees are known). We then briefly discuss how this decision problem can be modified to find the attacks themselves and conclude by examining the partial problem where not all initial weights or final acceptability degrees may be known.

Distributive theories evaluate distributions of goods based on candidate recipients’ characteristics, e.g. how well off candidates are, how deserving they are, and whether they fare below sufficiency. But such characteristics vary across possible worlds, so distributive theories may differ in terms of the world which for them settles candidates’ characteristics. This paper examines how distributive theories differ in terms of whether candidate recipients’ relevant characteristics are grounded in the possible world that would take place if the distributor does not intervene (...) (call it the “input” world) or if they are grounded in each possible world that the distributor can bring about through different decisions (call each an “output” world). We illustrate the importance of this distinction in relation to one distributive theory, prioritarianism. As we show, both input and output versions of prioritarianism are plausible interpretations of the literature, and there are good reasons to take input prioritarianism seriously. Ultimately, however, we argue that input prioritarianism should be rejected. (shrink)

How are new Bayesian hypotheses generated within the framework of predictive processing? This explanatory framework purports to provide a unified, systematic explanation of cognition by appealing to Bayes rule and hierarchical Bayesian machinery alone. Given that the generation of new hypotheses is fundamental to Bayesian inference, the predictive processing framework faces an important challenge in this regard. By examining several cognitive‐level and neurobiological architecture‐inspired models of hypothesis generation, we argue that there is an essential difference between the two types of (...) models. Cognitive‐level models do not specify how they can be implemented in brains and include structures and assumptions that are external to the predictive processing framework. By contrast, neurobiological architecture‐inspired models, which aim to better resemble brain processes, fail to explain important capacities of cognition, such as categorization and few‐shot learning. The “scaling‐up” challenge for proponents of predictive processing is to explain the relationship between these two types of models using only the theoretical and conceptual machinery of Bayesian inference.
