Embodied and extended cognition is a relatively new paradigm within cognitive science that challenges the basic tenet of classical cognitive science, viz. cognition consists in building and manipulating internal representations. Some of the pioneers of embodied cognitive science have claimed that this new way of conceptualizing cognition puts pressure on epistemological and ontological realism. In this paper I will argue that such anti-realist conclusions do not follow from the basic assumptions of radical embodied cognitive science. Furthermore I will show that (...) one can develop a form of realism that reflects rather than just accommodates the core principles of non-representationalist embodied cognitive science. (shrink)

The Public Policy Advisory Network on Female Genital Surgeries in Africa has written an article expressing concern about the media's inaccurate depiction of this practice and suggesting a more fact‐based approach to reporting on it. I applaud the network for soliciting input from various fields. I cannot agree more that some in the media have misconstrued, exaggerated, and used inflammatory language; words like “torture,” “barbaric,” and “horrific” will likely enrage readers while reinforcing discrimination against women who practice or have undergone (...) genital cutting. The authors also assert that “any genuine public policy debate should be grounded in the best available evidence and begins with fact checking.” Again, I couldn't agree more. My concern is that there is bias in the way some of the data are presented in this article. (shrink)

This paper provides a critical reflection on the nature of ethnic enclaves and segregation by presenting an analytical frame that can be used to capture the contested nature of spatiality in these spaces. By underscoring the dynamics in which differences constitute distinct subject positions, this paper posits a relational orientation to studying spatiality that is based on complex relations among and between subjects and space. To date, few attempts have been made to present an analytical frame for the analysis of (...) the spatiality of ethnic enclaves and segregation in which space becomes contested by different groups, occupants of space, and those external to space. This paper bridges this gap by synthesizing the relational approaches found in Bourdieusian field theory and Lefebvrian spatiality. This paper seeks to make three contributions. First, to provide an explicit theoretical anchor upon which relational and spatial theories converge since the underlying rationale for complementary is usually only implicitly evaluated. In detailing this convergence, the social constitution of reality and an emphasis on the duality between individuals and society as well as society and space are identified as a rationale for relational spatiality. Second, to demonstrate how a collective engagement with Bourdieu’s and Lefebvre’s approaches facilitates a recognition of spatiality as a polysemous social product and producer of social reality in addition to grounding this orientation as a critical dialectic engagement in which both the subjects and knowledge production cannot be neutral. Third, to present an analytical frame for the investigation of ethnic enclaves in and through which ethnic majorities, minorities, occupants of space, and those external to these enclaves constitute different views towards the same space.

Virtual fictionalism is the view that virtual reality is a kind of fiction. We imagine that what we see and hear in virtual reality is real, although it is not. The problem with this view is that there are real moral concerns with our use of virtual reality, from violent video games to cases of virtual groping on social platforms. If what we do in virtual reality is just make-believe, the fictionalist cannot explain the real moral harms of our virtual (...) actions. Call this the moral objection to virtual fictionalism. I address the objection in this paper by arguing for a new fictional account of virtual actions. Virtual fictionalists can take virtual actions to be happening within the fiction and consider users to act as characters or actors within the fictional world depicted in the virtual environment. Instead, I argue that virtual actions create fictional representations from outside the fiction; users act in virtual reality as an author might in their work. The alternative I present better addresses the moral objection to virtual fictionalism—it does not conflate the user with a fictional character. Our virtual actions create fictional representations, and we can morally evaluate them as such. (shrink)

In recent decades, non-representational approaches to mental phenomena and cognition have been gaining traction in cognitive science and philosophy of mind. In these alternative approach, mental representations either lose their central status or, in its most radical form, are banned completely. While there is growing agreement that non-representational accounts may succeed in explaining some cognitive capacities, there is widespread skepticism about the possibility of giving non-representational accounts of cognitive capacities such as memory, imagination or abstract thought. In this paper, I (...) will critically examine the view that there are fundamental limitations to non-representational explanations of cognition. Rather than challenging these arguments on general grounds, I will examine a set of human cognitive capacities that are generally thought to fall outside the scope of non-representational accounts, i.e. numerical cognition. After criticizing standard representational accounts of numerical cognition for their lack of explanatory power, I will argue that a non-representational approach that is inspired by radical enactivism offers the best hope for developing a genuine naturalistic explanatory account for these cognitive capacities.

BackgroundObtaining informed consent for participation in genomic research in low-income settings presents specific ethical issues requiring attention. These include the challenges that arise when providing information about unfamiliar and technical research methods, the implications of complicated infrastructure and data sharing requirements, and the potential consequences of future research with samples and data. This study investigated researchers’ and participants’ parents’ experiences of a consent process and understandings of a genome-wide association study of malaria involving children aged five and under in Mali. (...) It aimed to inform best practices in recruiting participants into genomic research.MethodsA qualitative rapid ethical assessment was undertaken. Fifty-five semi-structured interviews were conducted with the parents of research participants. An additional nine semi-structured interviews were conducted with senior research scientists, research assistants and with a member of an ethics committee. A focus group with five parents of research participants and direct observations of four consent processes were also conducted. French and translated English transcripts were descriptively and thematically coded using OpenCode software.ResultsParticipants’ parents in the MalariaGEN study had differing understandings of the causes of malaria, the rationale for collecting blood samples, the purposes of the study and the kinds of information the study would generate. Genomic aspects of the research, including the gene/environment interaction underlying susceptibility or resistance to severe malaria, proved particularly challenging to explain and understand.ConclusionsThis study identifies a number of areas to be addressed in the design of consent processes for genomic research, some of which require careful ethical analysis. These include determining how much information should be provided about differing aspects of the research and how best to promote understandings of genomic research. We conclude that it is important to build capacity in the design and conduct of effective and appropriate consent processes for genomic research in low and middle-income settings. Additionally, consideration should be given to the role of review committees and community consultation activities in protecting the interests of participants in genomic research. (shrink)

The `problem of time' is a cluster of interpretational and formal issues in the foundations of general relativity relating to both the representation of time in the classical canonical formalism, and to the quantization of the theory. The purpose of this short chapter is to provide an accessible introduction to the problem.

Symplectic reduction is a formal process through which degeneracy within the mathematical representations of physical systems displaying gauge symmetry can be controlled via the construction of a reduced phase space. Typically such reduced spaces provide us with a formalism for representing both instantaneous states and evolution uniquely and for this reason can be justifiably afforded the status of fun- damental dynamical arena - the otiose structure having been eliminated from the original phase space. Essential to the application of symplectic reduction (...) is the precept that the first class constraints are the relevant gauge generators. This prescription becomes highly problematic for reparameterization invariant theories within which the Hamiltonian itself is a constraint; not least because it would seem to render prima facie distinct stages of a history physically identical and observable functions changeless. Here we will consider this problem of time within non-relativistic me- chanical theory with a view to both more fully understanding the temporal struc- ture of these timeless theories and better appreciating the corresponding issues in relativistic mechanics. For the case of nonrelativistic reparameterization invariant theory application of symplectic reduction will be demonstrated to be both unnec- essary; since the degeneracy involved is benign; and inappropriate; since it leads to a trivial theory. With this anti-reductive position established we will then examine two rival methodologies for consistently representing change and observable func- tions within the original phase space before evaluating the relevant philosophical implications. We will conclude with a preview of the case against symplectic re- duction being applied to canonical general relativity. (shrink)

Econophysics is a new and exciting cross-disciplinary research field that applies models and modelling techniques from statistical physics to economic systems. It is not, however, without its critics: prominent figures in more mainstream economic theory have criticized some elements of the methodology of econophysics. One of the main lines of criticism concerns the nature of the modelling assumptions and idealizations involved, and a particular target are ‘kinetic exchange’ approaches used to model the emergence of inequality within the distribution of individual (...) monetary income. This article will consider such models in detail, and assess the warrant of the criticisms drawing upon the philosophical literature on modelling and idealization. Our aim is to provide the first steps towards informed mediation of this important and interesting interdisciplinary debate, and our hope is to offer guidance with regard to both the practice of modelling inequality, and the inequality of modelling practice. _1_ Introduction _1.1_ Econophysics and its discontents _1.2_ Against burglar economics _2_ Modelling Inequality _2.1_ Mainstream economic models for income distribution _2.2_ Econophysics models for income distribution _3_ Idealizations in Kinetic Exchange Models _3.1_ Binary interactions _3.2_ Conservation principles _3.3_ Exchange dynamics _ 4 _ Fat Tails and Savings _ 5 _ Evaluation.

We claim that, as it stands, the Deutsch–Wallace–Everett approach to quantum theory is conceptually incoherent. This charge is based upon the approach’s reliance upon decoherence arguments that conflict with its own fundamental precepts regarding probabilistic reasoning in two respects. This conceptual conflict obtains even if the decoherence arguments deployed are aimed merely towards the establishment of certain ‘emergent’ or ‘robust’ structures within the wave function: To be relevant to physical science notions such as robustness must be empirically grounded, and, on (...) our analysis, this grounding can only plausibly be done in precisely the probabilistic terms that lead to conceptual conflict. Thus, the incoherence problems presented necessitate either the provision of a new, non-probabilistic empirical grounding for the notions of robustness and emergence in the context of decoherence, or the abandonment of the Deutsch–Wallace–Everett programme for quantum theory.

Starting from a generalized Hamilton-Jacobi formalism, we develop a new framework for constructing observables and their evolution in theories invariant under global time reparametrizations. Our proposal relaxes the usual Dirac prescription for the observables of a totally constrained system and allows one to recover the influential partial and complete observables approach in a particular limit. Difficulties such as the non-unitary evolution of the complete observables in terms of certain partial observables are explained as a breakdown of this limit. Identification of (...) our observables relies upon a physical distinction between gauge symmetries that exist at the level of histories and states, and those that exist at the level of histories and not states. This distinction resolves a tension in the literature concerning the physical interpretation of the partial observables and allows for a richer class of observables in the quantum theory. There is the potential for the application of our proposal to the quantization of gravity when understood in terms of the Shape Dynamics formalism. (shrink)

A physically consistent semi-classical treatment of black holes requires universality arguments to deal with the ‘trans-Planckian’ problem where quantum spacetime effects appear to be amplified such that they undermine the entire semi-classical modelling framework. We evaluate three families of such arguments in comparison with Wilsonian renormalization group universality arguments found in the context of condensed matter physics. Our analysis is framed by the crucial distinction between robustness and universality. Particular emphasis is placed on the quality whereby the various arguments are (...) underpinned by ‘integrated’ notions of robustness and universality. Whereas the principal strength of Wilsonian universality arguments can be understood in terms of the presence of such integration, the principal weakness of all three universality arguments for Hawking radiation is its absence.

In 1981 Unruh proposed that fluid mechanical experiments could be used to probe key aspects of the quantum phenomenology of black holes. In particular, he claimed that an analogue to Hawking radiation could be created within a fluid mechanical `dumb hole', with the event horizon replaced by a sonic horizon. Since then an entire sub-field of `analogue gravity' has been created. In 2016 Steinhauer reported the experimental observation of quantum Hawking radiation and its entanglement in a Bose-Einstein condensate analogue black (...) hole. What can we learn from such analogue experiments? In particular, in what sense can they provide evidence of novel phenomena such as black hole Hawking radiation? (shrink)

The analysis of the temporal structure of canonical general relativity and the connected interpretational questions with regard to the role of time within the theory both rest upon the need to respect the fundamentally dual role of the Hamiltonian constraints found within the formalism. Any consistent philosophical approach towards the theory must pay dues to the role of these constraints in both generating dynamics, in the context of phase space, and generating unphysical symmetry transformations, in the context of a hypersurface (...) embedded within a solution. A first denial of time in the terms of a position of reductive temporal relationalism can be shown to be troubled by failure on the first count, and a second denial in the terms of Machian temporal relationalism can be found to be hampered by failure on the second. A third denial of time, consistent with both of the Hamiltonian constraints roles, is constituted by the implementation of a scheme for constructing observables in terms of correlations and leads to a radical Parmenidean timelessness. The motivation for and implications of each of these three denials are investigated. (shrink)

This article aims to study the intersection between critical realism and complexity theories through the existing literature on complex systems via an engagement with Luhmann’s autopoiesis. With reference to the philosophies of substance and persistence, I build on previous critical realist scholarship and provide an explanation for what the literature has only noted as the limitations and potentials of autopoiesis for complex systems thinking and its compatibility with Critical Realism. By highlighting how Luhmann’s autopoiesis is not a trans-immanent/ perdurantist-exdurantist system, (...) I show first how a trans immanent system through the method of calibration entails a complex causation involving objects in the environment of systems and not just within their boundaries. Second, I explain how a trans-immanent system fits with CR via the Morphogenetic Régulation framework by exploring the theme of crisis in terms of the movement from inadequate to adequate understanding of objects.

A small but growing number of studies have aimed to understand, assess and reduce existential risks, or risks that threaten the continued existence of mankind. However, most attention has been focused on known and tangible risks. This paper proposes a heuristic for reducing the risk of black swan extinction events. These events are, as the name suggests, stochastic and unforeseen when they happen. Decision theory based on a fixed model of possible outcomes cannot properly deal with this kind of event. (...) Neither can probabilistic risk analysis. This paper will argue that the approach that is referred to as engineering safety could be applied to reducing the risk from black swan extinction events. It will also propose a conceptual sketch of how such a strategy may be implemented: isolated, self-sufficient, and continuously manned underground refuges. Some characteristics of such refuges are also described, in particular the psychosocial aspects. Furthermore, it is argued that this implementation of the engineering safety strategy safety barriers would be effective and plausible and could reduce the risk of an extinction event in a wide range of possible scenarios. Considering the staggering opportunity cost of an existential catastrophe, such strategies ought to be explored more vigorously. (shrink)

The professions have focused considerable attention on developing codes of conduct. Despite their efforts there is considerable controversy regarding the propriety of professional codes of ethics. Many provisions of professional codes seem to exacerbate disputes between the profession and the public rather than providing a framework that satisfies the public''s desire for moral behavior.After examining three professional codes, we divide the provisions of professional codes into those provisions which urge professionals to avoid moral hazard, maintain professional courtesy and serve the (...) public interest. We note that whereas provisions urging the avoidance of moral hazard are uncontroversial, the public is suspicious of provisions protecting professional courtesy. Public interest provisions are controversial when the public and the profession disagree as to what is in the public interest. Based on these observations, we conclude with recommendations regarding the content of professional codes. (shrink)

A fundamental tenet of Paul Feyerabend’s pluralistic view of science has it that theory proliferation, that is, the availability of theoretical alternatives, is of crucial importance for the detection of anomalies in established theories. Paul Hoyningen-Huene calls this the Anomaly Importation Thesis, according to which anomalies are imported, as it were, into well-established theories from competing alternatives. This article pursues two major objectives: (a) to work out the systematic details of Feyerabend’s ideas on theory proliferation and anomaly import as they (...) are presented in his early publications and his Against Method and (b) to compare Feyerabend’s ideas on theory proliferation and anomaly import with corresponding features in Popper’s critical rationalist philosophy of science. As it turns out, neither the Principle of Proliferation nor the Anomaly Importation Thesis are necessarily incompatible with critical rationalism. In spite of Feyerabend’s general anti-Popperian attitude, I argue that theoretical pluralism can be seen as an advancement of the critical rationalist philosophy and that critical rationalism provides good arguments for pluralism.

In this work, we study a several species aerobic chemostat model with constant recycle sludge concentration in continuous culture. We reduce the number of parameters by considering a dimensionless model. First, the existence of a global positive uniform attractor for the model with different removal rates is proved using the theory of dissipative dynamical systems. Hence, we investigate the asymptotic behavior of the model under small perturbations using methods of singular perturbation theory and we prove that, in the case of (...) two species in competition, the unique equilibrium which is positive is globally asymptotically stable. Finally, we establish the link between the open problem of the chemostat with different removal rates and monotone functional responses, and our model when two species compete on the same nutrient. We give some numerical simulations to illustrate the results. (shrink)

Both mainstream cognitive science and analytic philosophy of mind remain wedded to the Cartesian picture of the mind as an isolated, self-sufficient, and constitutively individual phenomenon. However, recently approaches to the mind (e.g. extended mind thesis, enactivism) that depart from the standard view have emerged. Aunifying thread that runs through these approaches can be summed up in the slogan: “to understand mental phenomena one cannot do away with the environment”. Differences between these related views pertain to the strength of the (...) modal operator “cannot”. On the strongest reading the slogan implies that the mind is constituted by the environment. While this interpretation is akin to Marx view on the constitution of consciousness, this link is overlooked in the literature. In this paper, I will argue that Marxists philosophical thinking about the mind, as exemplified by the activity approach, offers a sound philosophical basis for the further development of post-Cartesian views in cognitive science and philosophy of mind. Furthermore, I will argue that the materialistic method proposed by these thinkers is the most promising approach to the problem of naturalizing the mind. (shrink)

Hamiltonian constraints feature in the canonical formulation of general relativity. Unlike typical constraints they cannot be associated with a reduction procedure leading to a non-trivial reduced phase space and this means the physical interpretation of their quantum analogues is ambiguous. In particular, can we assume that “quantisation commutes with reduction” and treat the promotion of these constraints to operators annihilating the wave function, according to a Dirac type procedure, as leading to a Hilbert space equivalent to that reached by quantisation (...) of the problematic reduced space? If not, how should we interpret Hamiltonian constraints quantum mechanically? And on what basis do we assert that quantisation and reduction commute anyway? These questions will be refined and explored in the context of modern approaches to the quantisation of canonical general relativity. (shrink)

As we learn more about the human brain, novel biotechnological means to modulate human behaviour and emotional dispositions become possible. These technologies could be used to enhance our morality. Moral bioenhancement, an instance of human enhancement, alters a person’s dispositions, emotions or behaviour in order to make that person more moral. I will argue that moral bioenhancement could be carried out in three different ways. The first strategy, well known from science fiction, is behavioural enhancement. The second strategy, favoured by (...) prominent defenders of moral bioenhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I will argue that we ought to implement a combination of the second and third strategies. Furthermore, I will argue that the usual arguments against other instances of human enhancement do not apply to moral bioenhancement, or apply only to the first strategy, behavioural enhancement.

This paper expands Rami Ali’s dissolution of the gamer’s dilemma (Ethics Inf Technol 17:267-274, 2015). Morgan Luck’s gamer’s dilemma (Ethics Inf Technol 11(1):31-36, 2009) rests on our having diverging intuition when considering virtual murder and virtual child molestation in video games. Virtual murder is seemingly permissible, when virtual child molestation is not and there is no obvious morally relevant difference between the two. Ali argues that virtual murder and virtual child molestation are equally permissible/impermissible when considered under different modes of (...) engagement. To this end, Ali distinguishes between story-telling gameplay and simulation games, discussing both in depth. I build on the dissolution by looking into competitive gameplay in order to consider what the morally relevant difference between virtual murder and virtual child molestation might be when competing in a video game. I argue that when competitors consent to participate in a competition, the rules of the competition supersede everyday moral intuitions. As such, virtual competitions ought to represent such consent from virtual characters. Virtual children cannot be represented as giving consent to be molested because (1) children cannot be represented as giving sexual consent, and (2) consent to be possibly molested cannot be given. This creates a morally relevant difference between murder and molestation. By fully addressing competitive gameplay, I answer Luck’s worry that Ali’s dissolution is incomplete (Ethics Inf Technol 20:157-162, 2018). (shrink)

This article will explore a problem which is related to our moral obligations towards species. Although the re-creation of extinct animals has been discussed to some degree both in lay deliberations as well as by scientists, advocates tend to emphasize the technological and scientific value of such an endeavour, and the “coolness” factor, 32–33, 2013). This article will provide an argument in favour of re-creation based on normative considerations. The environmentalist community generally accepts that it is wrong to exterminate species, (...) for reasons beyond any instrumental value these species may have. It is often also claimed that humanity has a collective responsibility to either preserve or at least to not exterminate species. These two beliefs are here assumed to be correct. The argument presented here departs from and places these two ideas in a deontological framework, from which it is argued that when humanity causes the extinction of a species, this is a moral transgression, entailing a residual obligation. Such an obligation implies a positive duty to mitigate any harm caused by our moral failure. In light of recent scientific progress in the field of genetic engineering, it will be argued that humanity has a prima facie obligation to re-create species whose extinction mankind may have caused, also known as de-extinction.

We give a new characterization of _SOP_ (the strict order property) in terms of the behaviour of formulas in any model of the theory as opposed to having to look at the behaviour of indiscernible sequences inside saturated ones. We refine a theorem of Shelah, namely a theory has _OP_ (the order property) if and only if it has _IP_ (the independence property) or _SOP_, in several ways by characterizing various notions in functional analytic style. We point out some connections (...) between dividing lines in first order theories and subclasses of Baire 1 functions, and give new characterizations of some classes and new classes of first order theories.

We study and characterize stability, the negation of the independence property (NIP) and the negation of the strict order property (NSOP) in terms of topological and measure theoretical properties of classes of functions. We study a measure theoretic property, Talagrand's stability, and explain the relationship between this property and the NIP in continuous logic. Using a result of Bourgain, Fremlin, and Talagrand, we prove almost definability and Baire 1 definability of coheirs assuming the NIP. We show that a formula has (...) the strict order property if and only if there is a convergent sequence of continuous functions on the space of φ‐types such that its limit is not continuous. We deduce from this a theorem of Shelah and point out the correspondence between this theorem and the Eberlein‐Šmulian theorem. (shrink)

Review of Bryan W. Roberts: Reversing the Arrow of Time, Cambridge University Press, 2022.

We define the notion has the NIP (not the independence property) in A, where A is a subset of a model, and give some equivalences by translating results from function theory. We also discuss the number of coheirs when A is not necessarily countable, and revisit the notion “ has the NOP (not the order property) in a model M”.

We analyse insufficient epistemic pluralism and associated problems in science-based policy advice during the COVID-19 pandemic drawing on specific arguments in Paul Feyerabend’s philosophy. Our goal is twofold: to deepen our understanding of the epistemic shortcomings in science-based policy during the pandemic, and to assess the merits and problems of Feyerabend’s arguments for epistemic pluralism as well as their relevance for policy-making. We discuss opportunities and challenges of integrating a plurality of viewpoints from within and outside science into policy advice (...) thus contributing to discussions about normative issues concerning evidence and expertise in policy-making.

An intelligent machine surpassing human intelligence across a wide set of skills has been proposed as a possible existential catastrophe. Among those concerned about existential risk related to artificial intelligence, it is common to assume that AI will not only be very intelligent, but also be a general agent. This article explores the characteristics of machine agency, and what it would mean for a machine to become a general agent. In particular, it does so by articulating some important differences between (...) belief and desire in the context of machine agency. One such difference is that while an agent can by itself acquire new beliefs through learning, desires need to be derived from preexisting desires or acquired with the help of an external influence. Such influence could be a human programmer or natural selection. We argue that to become a general agent, a machine needs productive desires, or desires that can direct behavior across multiple contexts. However, productive desires cannot sui generis be derived from non-productive desires. Thus, even though general agency in AI could in principle be created by human agents, general agency cannot be spontaneously produced by a non-general AI agent through an endogenous process. In conclusion, we argue that a common AI scenario, where general agency suddenly emerges in a non-general agent AI, such as DeepMind’s superintelligent board game AI AlphaZero, is not plausible.

This paper has three parts. First, we establish some of the basic model theoretic facts about, the Tsirelson space of Figiel and Johnson [20]. Second, using the results of the first part, we give some facts about general Banach spaces. Third, we study model‐theoretic dividing lines in some Banach spaces and their theories. In particular, we show: (1) has the non independence property (NIP); (2) every Banach space that is ℵ0‐categorical up to small perturbations embeds c0 or () almost isometrically; (...) consequently the (continuous) first‐order theory of does not characterize, up to almost isometric isomorphism.
