Drawing on the performance appraisal and medical literatures, we examine representative ethical issues involved in current appraisal practices of individual physicians: the use of invalid and unreliable measures; organizational goals conflicting with patient health goals; using individual measures for what are group performance results; making individual attributions for what are systemic causes ; and using clinical feedback for organizational purposes. Suggestions for developing more ethical performance appraisals include reflecting upon the multiple purposes and means of appraisals, and the limitations of (...) current practices. Greater understanding of the effects of current appraisal practices on physicians can help minimize its potentially adverse consequences on the delivery of quality healthcare. (shrink)

The de‐repression of transposable elements (TEs) in mammalian genomes is thought to contribute to genome instability, inflammation, and ageing, yet is viewed as a cell‐autonomous event. In contrast to mammalian cells, prokaryotes constantly exchange genetic material through TEs, crossing both cell and species barriers, contributing to rapid microbial evolution and diversity in complex communities such as the mammalian gut. Here, it is proposed that TEs released from prokaryotes in the microbiome or from pathogenic infections regularly cross the kingdom barrier to (...) the somatic cells of their eukaryotic hosts. It is proposed this horizontal transfer of TEs from microbe to host is a stochastic, ongoing catalyst of genome destabilization, resulting in structural and epigenetic variations, and activation of well‐evolved host defense mechanisms contributing to inflammation, senescence, and biological ageing. It is proposed that innate immunity pathways defend against the horizontal acquisition of microbial TEs, and that activation of this pathway during horizontal transposon transfer promotes chronic inflammation during ageing. Finally, it is suggested that horizontal acquisition of prokaryotic TEs into mammalian genomes has been masked and subsequently under‐reported due to flaws in current sequencing pipelines, and new strategies to uncover these events are proposed.

Biobanks are increasingly being created specifically for research purposes. Concomitantly, we are seeing significant and evolving shifts in research ethics in relation to biobanking. Three discrete shifts are identified in this article. The first extends the ethical focus beyond the protection of human subjects to the promotion of broader community benefits of research utilizing biobanked resources, and an expectation that these benefits will be shared. The second involves the evolution of the traditional consent paradigm for future research uses of biobanks (...) resources that are not in contemplation at the time of donation. The third involves a move away from single project management to more dynamic governance accountability to research participants and the public. These shifts may take different local and institutional forms but share common recognizable elements. (shrink)

This book is a rich blend of analyses by leading experts from various cultures and disciplines. A compact introduction to a complex field, it illustrates biotechnology's profound impact upon the environment and society. Moreover, it underscores the vital relevance of cultural values. This book empowers readers to more critically assess biotechnology's value and effectiveness within both specific cultural and global contexts.

BackgroundWe conducted a survey to identify what types of health/medical research could be exempt from research ethics reviews in Australia.MethodsWe surveyed Australian health/medical researchers and Human Research Ethics Committee members. The survey asked whether respondents had previously changed or abandoned a project anticipating difficulties obtaining ethics approval, and presented eight research scenarios, asking whether these scenarios should or should not be exempt from ethics review, and to provide comments. Qualitative data were analysed thematically; quantitative data in R.ResultsWe received 514 responses. (...) Forty-three per cent of respondents to whom the question applied, reported changing projects in anticipation of obstacles from the ethics review process; 25% reported abandoning projects for this reason. Research scenarios asking professional staff to provide views in their area of expertise were most commonly exempted from ethics review ; scenarios involving surplus samples and N-of-1 studies were most commonly required to undergo ethics review. HREC members were 26% more likely than researchers to require ethics review. Need for independent oversight, and low risk, were most frequently cited in support of decisions to require or exempt from ethics review, respectively.ConclusionsConsiderable differences exist between researchers and HREC members, about when to exempt from review the research that ultimately serves the interests of patients and the public. It is widely accepted that evaluative research should be used to reduce clinical uncertainties—the same principle should apply to ethics reviews. (shrink)

Here the extension of a sentence token is a truth-value, the extension of a name is an individual, and so on. Scenarios are most often understood as centered possible worlds – i.e. ordered triples of worlds, individuals, and times - although they may also be understood in other ways.

Mechanistic interpretability is the program of explaining what AI systems are doing in terms of their internal mechanisms. I analyze some aspects of the program, along with setting out some concrete challenges and assessing progress to date. I argue for the importance of propositional interpretability, which involves interpreting a system’s mechanisms and behav- ior in terms of propositional attitudes: attitudes (such as belief, desire, or subjective probabil- ity) to propositions (e.g. the proposition that it is hot outside). Propositional attitudes are (...) the central way that we interpret and explain human beings and they are likely to be central in AI too. A central challenge is what I call thought logging: creating systems that log all of the rel- evant propositional attitudes in an AI system over time. I examine currently popular methods of interpretability (such as probing, sparse auto-encoders, and chain of thought methods) as well as philosophical methods of interpretation (including those grounded in psychoseman- tics) to assess their strengths and weaknesses as methods of propositional interpretability.

In June 2001, the American Medical Association (AMA) issued a revised and expanded version of the Principles of Medical Ethics (last published in 1980). In light of the new and more comprehensive document, the present essay is geared to consideration of a longstanding tension between physician's autonomy rights and societal obligations in the AMA Code. In particular, it will be argued that a duty to treat overrides AMA autonomy rights in social emergencies, even in cases that involve personal risk to (...) physicians (e.g., bioterrorist attack, HIV infection, SARS). The argument will be made by way of the logic and language of the AMA Code through its history, commentaries, and precedents. It also will be shown that there are substantial reasons to believe that the logic of the Code is sound in morally relevant ways. The essay will conclude with some philosophical proposals suggesting a framework for the duty to render aid and the extension of those duties to physicians facing personal risks. (shrink)

This paper is an edited transcription of a talk at the 1997 Montreal symposium on "Consciousness at the Frontiers of Neuroscience". There's not much here that isn't said elsewhere, e.g. in "Facing Up to the Problem of Consciousness" and "How Can We Construct a Science of Consciousness?"]].

Chalmers e Dennett se encontram em lados opostos da discussão do problema da consciência. Para Chalmers, ela é um dado indubitável que não pode ser explicada em termos de outra coisa. Para Dennett, o que existe verdadeiramente são múltiplos julgamentos sobre nossa consciência. Cada um acusa o outro de circularidade. Isto só é possível porque a diferença entre estas duas teorias é verdadeiramente uma diferença de princípios. A mesma oposição que encontramos no aparato teórico encontramos também em suas pressuposições mais (...) básicas e fundamentais. Este fato torna extremamente difícil escolher entre as duas ao mesmo tempo em que radicaliza a diferença entre elas. De um lado temos que argumentos podem refutar intuições, de outro temos que é preciso primeiro sondar nossas intuições para depois criar argumentos a partir delas. Entre um extremo e outro nos encontramos com o velho dilema de “o que vem primeiro?”. No entanto, mais importante do que escolher lados é mostrar o quanto é difícil escolher. (shrink)

This paper challenges David Chalmers' proposed division of the problems of consciousness into the `easy' ones and the `hard' one, the former allegedly being susceptible to explanation in terms of computational or neural mechanisms and the latter supposedly turning on the fact that experiential `qualia' resist any sort of functional definition. Such a division, it is argued, rests upon a misrepresention of the nature of human cognition and experience and their intimate interrelationship, thereby neglecting a vitally important insight of Kant. (...) From a Kantian perspective, our capacity for conceptual thought is so inextricably bound up with our capacity for phenomenal consciousness that it is an illusion to imagine that there are any `easy' problems of consciousness, resolvable within the computational or neural paradigms.

In this paper I examine Chalmers and Jackson’s defence of the a priori entailment thesis, that is, the claim that microphysical truths a priori entail ordinary non-phenomenal truths such as ‘water covers 60% of the Earth surface’, which they use as a premise for an argument against the possibility of a reductive explanation of consciousness. Their argument relies on a certain view about the possession conditions of macroscopic concepts such as WATER, known as ascriptivism. In the paper I distinguish two (...) versions of ascriptivism: reductive versus non-reductive ascriptivism. According to reductive ascriptivism, competent users of a concept have the ability to infer truths involving such concept from lower-level truths, whereas according to non-reductive ascriptivism, all that is required in order to be a competent user of a concept is to be able to infer truths involving that concept from other truths, which need not be lower-level truths. I argue, first, that the a priori entailment thesis is committed to reductive ascriptivism, and secondly, that reductive ascriptivism is problematic because it trivializes the notion of a priori knowledge. Therefore, I conclude that Chalmers and Jackson have not presented a convincing case for the claim that microphysical truths entail ordinary non-phenomenal truths a priori, especially when we understand this claim in the sense that is relevant for their argument against the possibility of a reductive explanation of consciousness.

The inference from conceivability to possibility has been challenged in numerous ways. One of these ways is the so-called phenomenal concept strategy, which has become one of the main strategies against the conceivability argument against physicalism. However, David Chalmers has recently presented a dilemma for the phenomenal concept strategy, and he has argued that no version of the strategy can succeed. In this paper, I examine the dilemma, and I argue that there is a way out of it. I conclude (...) that Chalmers has not posed any serious problem for the phenomenal concept strategy to succeed in blocking the conceivability argument. In doing so, my aim is not only to show that Chalmers’s argument has not refuted the phenomenal concept strategy, but also to clarify what any version of the strategy should achieve in order to be successful.

When I say that my conception of metaphysics is Aristotelian, or neo-Aristotelian, this may have more to do with Aristotle’s philosophical methodology than his metaphysics, but, as I see it, the core of this Aristotelian conception of metaphysics is the idea that metaphysics is the first philosophy . In what follows I will attempt to clarify what this conception of metaphysics amounts to in the context of some recent discussion on the methodology of metaphysics (e.g. Chalmers et al . (2009), (...) Ladyman and Ross (2007)). There is a lot of hostility towards the Aristotelian conception of metaphysics in this literature: for instance, the majority of the contributors to the Metametaphysics volume assume a rather more deflationary, Quinean approach towards metaphysics. In the process of replying to the criticisms towards Aristotelian metaphysics put forward in recent literature I will also identify some methodological points which deserve more attention and ought to be addressed in future research.

The meta-problem is 'the problem of explaining why we think that there is a problem of consciousness' (Chalmers, 2018, p. 6). This presupposes that we think there is a problem in the first place. We challenge the breadth of this 'we', arguing that there is already sufficient empirical evidence to cast doubt on the claim. We then add to this body of evidence, presenting the results of a new cross-cultural study extending the work of Sytsma and Machery (2010).

According to many philosophers, there is an explanatory gap between physical truths and phenomenal truths. Someone could know all the physical truths about the world, and in particular, all the physical information about the brain and the neurophysiology of vision, and still not know what it is like to see red (Jackson 1982, 1986). According to a similar example, someone could know all the physical truths about bats and still not know what it is like to be a bat (Nagel (...) 1974). We can conceive of an individual that is physically identical to me, molecule per molecule, but does not have any phenomenally conscious state whatsoever (Chalmers 1996). Some philosophers have argued that the explanatory gap shows that we cannot explain consciousness in physical terms (Levine 2001), or even that phenomenal consciousness is not physical and therefore physicalism is false (Chalmers 1996, 2002).

Do psychological traits predict philosophical views? We administered the PhilPapers Survey, created by David Bourget and David Chalmers, which consists of 30 views on central philosophical topics (e.g., epistemology, ethics, metaphysics, philosophy of mind, and philosophy of language) to a sample of professional philosophers (N = 314). We extended the PhilPapers survey to measure a number of psychological traits, such as personality, numeracy, well-being, lifestyle, and life experiences. We also included non-technical ‘translations’ of these views for eventual use in other (...) populations. We found limited to no support for the notion that personality or demographics predict philosophical views. We did, however, find that some psychological traits were predictive of philosophical views, even after strict correction for multiple comparisons. Findings include: higher interest in numeracy predicted physicalism, naturalism, and consequentialism; lower levels of well-being and higher levels of mental illness predicted hard determinism; using substances such as psychedelics and marijuana predicted non-realist and subjectivist views of morality and aesthetics; having had a transformative or self-transcendent experience predicted theism and idealism. We discuss whether or not these empirical results have philosophical implications, while noting that 68% of our sample of professional philosophers indicated that such findings would indeed have philosophical value.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to OckhamJeffrey E. BrowerPaul Vincent Spade, editor. The Cambridge Companion to Ockham. Cambridge: Cambridge University Press, 1999. Pp. xii + 400. Cloth, $54.95.Contemporary analytic philosophers have always been among the most enthusiastic audiences for the volumes in the Cambridge Companion series. And of all the great philosophers of the Middle Ages, perhaps none has appealed more to their sensibilities than William Ockham. It is fitting, (...) therefore, that after the publication of the Companion to Aquinas—the first volume in the series devoted to a medieval philosopher—there should appear a Companion to Ockham.The fifteen chapters comprising this volume survey the entire range of Ockham's thought and may conveniently be divided into four main parts. The first part (chaps. 2-7) deals with Ockham's most enduring legacy: his contribution to issues falling within the domain of logic, philosophy of language, and metaphysics. The second part (chaps. 8-9) is devoted to issues in epistemology and philosophy of mind/cognition. The third part (chaps. 10-13) focuses on Ockham's views in ethics, action theory, and political philosophy. And the fourth part (chaps. 14-15) considers aspects of his philosophical theology. In addition, there is also an historical chapter (chap. 1), placing Ockham's life and works in their late-medieval intellectual context, and a brief editor's introduction, including a very useful list of all Ockham's writings, together with the best (sometimes, the only) Latin editions and English translations available.The volume is well organized and beautifully conceived. Some chapters are quite difficult, and in places contain material that is likely to be unfamiliar even to specialists in medieval philosophy. But the way in which they have been organized maximizes their usefulness and accessibility to specialists and non-specialists alike. The earlier parts of the volume lay the foundation for later ones, and the individual chapters within each part are arranged so as to build on and complement one another. This is perhaps most evident in the five chapters comprising the first part. Calvin Normore's presentation ofOckham's logic (in chap. 2) nicely prepares the reader for Claude Panaccio's discussion (in chap. 3) of Ockham's theory of mental language. Panaccio's chapter, in turn, provides the framework for David Chalmer's analysis (in chap. 4) of the debate over whether [End Page 588] Ockham's mental language permits synonymous expressions. Again, these three chapters taken together provide important background for Paul Spade's treatment (in chap. 5) of Ockham's views in metaphysics, which are closely related to his logic and philosophy of language. Finally, Gyula Klima's discussion (in chap. 6) ofhow Ockham's views in semantics and ontology differ from those of his predecessors, and André Goddu's discussion (in chap. 7) of Ockham's philosophy of nature, can be fully appreciated only against the background of the preceding chapters.What is perhaps most impressive about the volume, however, is the extent to which it succeeds at providing a systematic introduction to Ockham's philosophical achievement. All the chapters are, to some extent, concerned with matters of textual analysis and interpretation. But most of them involve much more than a mere survey of Ockham's texts. For example, in each of the four main parts, there is at least one chapter that attempts to locate Ockham's views in relation to those of his predecessors or contemporaries (such as Aquinas and Scotus), with the result that we get a sense of Ockham's place in the major medieval debates to which he contributed. At the same time, the volume introduces us to some of the most lively current debates in Ockham scholarship. It does this, not merely by summarizing them, but by actually carrying them out over the course of its chapters. For example, Eleonore Stump provides a sophisticated defense (in chap. 8) of what has become a standard interpretation of Ockham's theory of intuitive and abstractive cognition. In the following chapter, however, Elizabeth Karger rejects the standard interpretation on the basis of a re-reading of certain key texts. Again, in the first part of the volume there is a running debate... (shrink)

In this commentary on Chalmers’s work on the meta-problem of consciousness, I defend an approach to the meta-problem that Chalmers finds unpromising (i.e., what Chalmers has called the “use-mention fallacy” strategy.) The core of this strategy is the idea that thinking about consciousness requires a special mode of thought that activates phenomenal consciousness itself, which then facilitates a (mistaken) intuition that a first-person thought of consciousness and a third-person thought of a brain state cannot refer to the same thing. Chalmers (...) considers this strategy as offering a diagnosis in terms of the “use-mention fallacy” and dismisses it quickly. However, close examination shows that the strategy is not about a use-mention confusion. Also, a revision to this strategy can provide an account that withstands counterexamples and connects with many ideas that may lead to a solution to the meta-problem. (shrink)

O Argumento dos Zumbis proposto por Chalmers, ao contrário de defender o dualismo, bane as qualia para um “mundo” onde elas não podem influenciar o julgamento que fazemos sobre nós mesmos. Por este motivo, pelo próprio argumento, podemos ser um zumbi e não saber. A isso Chalmers chamou de The Paradox of Phenomenal Judgment. O problema é que ele aceita tal paradoxo como parte de sua própria teoria. No entanto, este movimento filosófico não é aceitável e este paradoxo mina a (...) teoria de Chalmers por dentro mostrando que o argumento dos zumbis é, na verdade, um argumento contra o dualismo. Chalmers tenta resolver este problema com uma série de argumentos que tem como base o fato de que a consciência é um bruto explanandum indubitável. No entanto, tal tentativa fracassa por uma série de razões que mostram que mesmo se ele estivesse correto, ainda poderíamos ser um zumbi e não saber. (shrink)

The textbook presentation of quantum mechanics, in a nutshell, is this. The physical state of any isolated system evolves deterministically in accordance with Schrödinger's equation until a "measurement" of some physical magnitude M (e.g. position, energy, spin) is made. Restricting attention to the case where the values of M are discrete, the system's pre-measurement state-vector f is a linear combination, or "superposition", of vectors f1, f2,... that individually represent states that..

Chalmers’ meta-problem of consciousness is the problem of explaining “problem reports”; i.e. reports to the effect that phenomenal consciousness has the various features that give rise to the hard problem. Chalmers (Journal of Consciousness Studies 25: 6–61, 2018, 8) suggests that solving the meta-problem will likely “shed significant light on the hard problem.” Against this, I argue that work on the meta-problem will likely fail to make the hard problem any easier. For each of the main stances on the hard (...) problem can provide an account of problem reports, and we have no way of deciding which of these accounts gives the correct explanation of an individual’s problem reports without presupposing a stance on the hard problem. We thus cannot determine which of the available solutions to the meta-problem is correct without having already solved the hard problem. (shrink)

According to David Chalmers, the hard problem of consciousness consists of explaining how and why qualitative experience arises from physical states. Moreover, Chalmers argues that materialist and reductive explanations of mentality are incapable of addressing the hard problem. In this chapter, I suggest that Chalmers’ hard problem can be usefully distinguished into a ‘how question’ and ‘why question,’ and I argue that evolutionary biology has the resources to address the question of why qualitative experience arises from brain states. From this (...) perspective, I discuss the different kinds of evolutionary explanations (e.g., adaptationist, exaptationist, spandrel) that can explain the origins of the qualitative aspects of various conscious states. This argument is intended to clarify which parts of Chalmers’ hard problem are amenable to scientific analysis. (shrink)

What is the status of a cat in a virtual reality environment? Is it a real object? Or part of a fiction? Virtual realism, as defended by D. J. Chalmers, takes it to be a virtual object that really exists, that has properties and is involved in real events. His preferred specification of virtual realism identifies the cat with a digital object. The project of this paper is to use a comparison between virtual reality environments and scientific computer simulations to (...) critically engage with Chalmers’s position. I first argue that, if it is sound, his virtual realism should also be applied to objects that figure in scientific computer simulations, e.g. to simulated galaxies. This leads to a slippery slope because it implies an unreasonable proliferation of digital objects. A philosophical analysis of scientific computer simulations suggests an alternative picture: The cat and the galaxies are parts of fictional models for which the computer provides model descriptions. This result motivates a deeper analysis of the way in which Chalmers builds up his realism. I argue that he buys realism too cheap. For instance, he does not really specify what virtual objects are supposed to be. As a result, rhetoric aside, his virtual realism isn’t far from a sort of fictionalism. (shrink)

Sentience, defined as the unconscious capacity of having conscious feeling experiences, is a psychobiological phenomenon involving dynamic patterns of electrochemical waves in living systems. The process of feeling can be studied in two ways: a) Empirical identification and analysis of the universal temporal patterns that characterize feeling, forming a science to be called Sentiomics; b) Introspective identification and report of the variety of qualitative conscious experiences, from a first-person perspective, a study that could be called Qualiomics. Qualiomics is undoubtedly a (...) challenge to conventional science, as stated in the “hard problem of consciousness” (Chalmers, 1995), as the first-person perspective is not accessible to conventional scientific measurement methods and explanations. Sentiomics, focusing on dynamic patterns that define the capacity to feel, is therefore susceptible to empirical and experimental treatment. In this article, we propose to contextualize the philosophical assumptions and problems of Sentiomics and present some of its various applications, focusing on its the relation with music. (shrink)

From an investigation of the theoretical, structural, methodological, and conceptual rudiments of the neurophenomenology, such as developed by Francisco Javier Varela, I seek, at first, to investigate the possibility of a theoretical model whose purpose consists in the integration between the subjective experience and the cerebral dynamic. To the study of the fundamental diagnosis of neurophenomenology — namely, the interpretation which Varela offers to the theoretical and methodological position of Chalmers’ ‘hard problem’ of consciousness —, I will associate the conception (...) of downward determination I borrow from the emergentism. My intention is to demonstrate that the notion of downward determination — as exemplified in meditative practice — can greatly contribute to the consolidation of a theoretical perspective for the problem of mind-body-life relations which is beyond the theoretical, structural, methodological and conceptual implications of the highly acclaimed ‘explanatory gap’. From my belief that meditation brings with it the possibility of filling the mind-body gap on a phenomenological level, I proceed to investigate the elements through which Buddhism and phenomenology can mutually benefit the sciences cognitive; in this sense, I am not presupposing the limitations, but rather the possibilities and the scope of the introspective method, as Varela has previously done in his neurophenomenology.

O presente artigo pretende apresentar e avaliar criticamente o projeto racionalista de David Chalmers e Frank Jackson na interpretação epistêmica da chamada semântica bidimensional. Diferentes versões do aparato formal da semântica bidimensional são lançadas para resolver certos problemas no âmbito da filosofia da linguagem, a saber, dar conta do conteúdo semântico de termos indexicais, produzir uma explicação para os híbridos modais como instâncias do necessário a posteriori e contribuir para o debate acerca da determinação do conteúdo mental. De um modo (...) geral, a semântica bidimensional estipula uma dupla dependência de expressões linguísticas frente a possibilidades ou cenários. Uma das noções centrais para a construção das possibilidades relevantes é a noção de “cenário”. O presente trabalho procura responder a duas objeções aa noção de cenário empregada por David Chalmers em sua interpretação do aparato bidimensional. AbstractThis paper aims at presenting and critically assessing the epistemic interpretation advanced by David Chalmers and Frank Jackson of the two-dimensional semantic framework. Different versions of the formal apparatus of the two-dimensional framework are used to account for philosophical phenomena such as the content of indexical terms, modal hybrids, such as posteriori necessities and the individuation of mental content. Generally, two-dimensional framework stipulates a double dependence of linguistic terms on possibilities or scenarios. One of the central notions for the construction of the relevant kind of possibility is the notion of “scenario”. The aim of the paper is to defend the two- dimensional framework from two objections regarding the notion of scenario. (shrink)

: Artificial intelligences and robots increasingly mimic human mental powers and intelligent behaviour. However, many authors claim that ascribing human mental powers to them is both conceptually mistaken and morally dangerous. This article defends the view that artificial intelligences can have human-like mental powers, by claiming that both human and artificial minds can be seen as extended minds – along the lines of Chalmers and Clark’s view of mind and cognition. The main idea of this article is that the Extended (...) Mind Model is independently plausible and can easily be extended to artificial intelligences, providing a solid base for concluding that artificial intelligences possess minds. This may warrant viewing them as morally responsible agents. Keywords: Artificial Intelligence; Mind; Moral Responsibility; Extended Cognition Intelligenze artificiali come menti estese. Perché no? Riassunto: Intelligenze artificiali e robot simulano in misura sempre crescente le capacità mentali e i comportamenti intelligenti umani. Molti autori, tuttavia, sostengono che attribuire loro capacità mentali umane sia concettualmente errato e moralmente pericoloso. In questo lavoro si difende l’idea per cui le intelligenze artificiali possano avere capacità mentali simili a quelle umane, sostenendo che menti umane e artificiali possano essere considerate come menti estese – sulla scorta della prospettiva di Chalmers e Clark circa la mente e la cognizione. L’idea principale alla base di questo lavoro è che il Modello della Mente Estesa abbia plausibilità a prescindere e che possa essere facilmente esteso alle intelligenze artificiali, fornendo una base solida per concludere che le intelligenze artificiali possiedano delle menti e si possano considerare come agenti moralmente responsabili.

Chalmers (The character of consciousness, 2010) argues for an acquaintance theory of the justification of direct phenomenal beliefs. A central part of this defense is the claim that direct phenomenal beliefs are cognitively significant. I argue against this. Direct phenomenal beliefs are justified within the specious present, and yet the resources available with the present ‘now’ are so impoverished that it barely constrains the content of a direct phenomenal belief. I argue that Chalmers’s account does not have the resources for (...) explaining how direct phenomenal beliefs support the inference from ‘this E is R’ to ‘that was R.’. (shrink)

Quine challenged traditional views of the a priori by appealing to two key premises: that any statement may be held true “come what may” and that no statement is immune to revision in light of new experience. Chalmers has recently developed a seemingly compelling response to each of these claims. The critique is particularly threatening because it seems to rest on the Bayesian premise that upon acquiring evidence E, a rational agent will update her credence in any statement S to (...) equal her prior conditional credence in S given E. We argue that Chalmers’s criticisms misfire. When properly understood, Quine’s two theses are largely consistent with Bayesianism. (shrink)

Background: how mind functions is subject to continuing scientific discussion. A simplistic approach says that, since no convincing way has been found to model subjective experience, mind cannot exist. A second holds that, since mind cannot be described by classical physics, it must be described by quantum physics. Another perspective concerns mind's hypothesized ability to interact with the world of quanta: it should be responsible for reduction of quantum wave packets; physics producing 'Objective Reduction' is postulated to form the basis (...) for mind-matter interactions. This presentation describes results derived from a new approach to these problems. It is based on well-established biology involving physics not previously applied to the fields of mind, or consciousness studies, that of critical feedback instability. -/- Methods: 'self-organized criticality' in complexity biology places system loci of control at critical instabilities, physical properties of which, including information properties, are presented. Their elucidation shows that they can model hitherto unexplained properties of experience. -/- Results: All results depend on physical properties of critical instabilities. First, at least one feed-back or feed-forward loop must have feedback gain, g = 1: information flows round the loop impress perfect images of system states back on themselves: they represent processes of perfect self-observation. This annihilates system quanta: system excitations are instability fluctuations, which cannot be quantized. Major results follow: -/- 1. Information vectors representing criticality states must include at least one attached information loop denoting self-observation. -/- 2. Such loop structures are attributed a function, 'registering the state's own existence', explaining -/- a. Subjective 'awareness of one's own presence' -/- b. How content-free states of awareness can be remembered (Jon Shear) -/- c. Subjective experience of time duration (Immanuel Kant) -/- d. The 'witness' property of experience – often mentioned by athletes 'in the zone' -/- e. The natural association between consciousness and intelligence -/- This novel, physically and biologically sound approach seems to satisfactorily model subjectivity. -/- Further significant results follow: -/- 1. Registration of external information in excited states of systems at criticality reduces external wave-packets: the new model exhibits 'Objective Reduction' of wave packets. -/- 2. High internal coherence (postulated by Domash & Penrose) leading to a. Non-separable information vector bundles. b. Non-reductive states (Chalmers's criterion for experience). -/- 3. Information that is: a. encoded in coherence negentropy; b. non-digitizable, and therefore c. computationally without digital equivalent (posited by Penrose). -/- Discussion and Conclusions: instability physics implies anharmonic motion, preventing excitation quantization, and totally different from the quantum physics of simple harmonic motion at stability. Instability excitations are different from anything hitherto conceived in information science. They can model aspects of mind never previously treated, including genuine subjectivity, objective reduction of wave-packets, and inter alia all properties given above. (shrink)

Some cognitive states — e.g. states of thinking, calculating, navigating — may be partially external because, at least sometimes, these states depend on the use of symbols and artifacts that are outside the body. Maps, signs, writing implements may sometimes be as inextricably bound up with the workings of cognition as neural structures or internally realized symbols (if there are any). According to what Clark and Chalmers [1998] call active externalism, the environment can drive and so partially constitute cognitive processes. (...) Where does the mind stop and the rest of the world begin? If active externalism is right, then the boundary cannot be drawn at the skull. The mind reaches – or at least can reach --- beyond the limits of the body out into the world. (shrink)

Chalmers suggests that, if a Singularity fails to occur in the next few centuries, the most likely reason will be 'motivational defeaters' i.e. at some point humanity or human-level AI may abandon the effort to create dramatically superhuman artificial general intelligence. Here I explore one plausible way in which that might happen: the deliberate human creation of an 'AI Nanny' with mildly superhuman intelligence and surveillance powers, designed either to forestall Singularity eternally, or to delay the Singularity until humanity more (...) fully understands how to execute a Singularity in a positive way. It is suggested that as technology progresses, humanity may find the creation of an AI Nanny desirable as a means of protecting against the destructive potential of various advanced technologies such as AI, nanotechnology and synthetic biology.
