Despite its centrality in the philosophy of cognitive science, there has been little prior philosophical work engaging with the notion of representation in contemporary NLP practice. This paper attempts to fill that lacuna: drawing on ideas from cognitive science, I introduce a framework for evaluating the representational claims made about components of neural NLP models, proposing three criteria with which to evaluate whether a component of a model represents a property and operationalising these criteria using probing classifiers, a (...) popular analysis technique in NLP (and deep learning more broadly). The project of operationalising a philosophically-informed notion of representation should be of interest to both philosophers of science and NLP practitioners. It affords philosophers a novel testing-ground for claims about the nature of representation, and helps NLPers organise the large literature on probing experiments, suggesting novel avenues for empirical research.

Eight research protocols which had previously been approved by Ethical Research Committees (ERCs) were reviewed in simulated review committees set up during a symposium on medical ethics. Only three protocols were considered to provide fully adequate information to allow ethical review and only one protocol was thought to provide sufficient guarantees on the ethical issues raised by the proposed research. For five other protocols additional safeguards were considered necessary, in particular covering the problem of informed consent. Two protocols were considered (...) to raise unresolvable ethical issues. This artificial exercise does not establish that review by ERCs is ineffective. It does highlight the lack of objective criteria in ethical review. Peer review by exchange of protocols between ERCs could assist in increasing the consistency in the application of ethical standards. (shrink)

David Chalmers advocates the view that the phenomenon of consciousness is fundamentally different from all other phenomena studied in the life sciences, positing a uniquely hard problem that precludes the possibility of a mechanistic explanation. In this paper, I evaluate three demarcation criteria for dividing phenomena into hard and easy problems: functional definability, the puzzle of the accompanying phenomenon, and the first-person data of subjective experience. I argue that none of the proposed criteria can accurately discriminate between the (...) phenomenon of consciousness and mechanistically explainable phenomena. (shrink)

While there are companies whose codes of ethics state that mere appearance of unethical behavior by employees is morally unacceptable, this so‐called appearance standard has hardly received any attention in the business ethics literature. Using corporate integrity theory, this article explores the criteria that may explain how mere appearances of unethical behavior can arise (i.e., the presence of conflicts of interests, the entanglement of these interests, a reputation for lack of integrity, and deviant outcomes) and those that may make (...) such appearances morally unacceptable (i.e., foreseeability, avoidability, and seriousness). The article proposes remedies for preventing and resolving instances when mere appearance of unethical behavior is morally unacceptable. (shrink)

This paper studies the question: How should one handle inconsistencies that derive from the inadequacy of the criteria by which one approaches the world. I compare several approaches. The adaptive logics defined from CLuN appear to be superior to the others in this respect. They isolate inconsistencies rather than spreading them, and at the same time allow for genuine deductive steps from inconsistent and mutually inconsistent premises. Yet, the systems based on CLuN seem to introduce an asymmetry betweennegated and (...) non-negated formulas, and this seems hard to justify. To clarify and understand the source of the asymmetry, the epistemological presuppositions of CLuN, viz. inadequate criteria, are investigated. This leads to a new type of paraconsistent logic that involves gluts with respect to all logical symbols. The larger part of the paper is devoted to this logic, to the adaptive logics defined from it, and to the properties of these systems. While the resulting logics are sensible and display interesting features, the search for variants of the justification leads to an unexpected justification for CLuN. (shrink)

[opening paragraph]: In his keynote paper David Chalmers defines ‘the hard problem’ by posing certain ‘Why’ questions about consciousness? Such questions must be posed within an appropriate setting. The way of science is to try to deduce the answer to many such questions from a few well defined assumptions. Much about nature can be explained in terms of the principles of classical mechanics. The assumptions, in this explanatory scheme, are that the world is composed exclusively of particles and fields governed (...) by specified mathematical laws that refer neither to any individual person, nor to anyone’s experiences. These physical laws are supposed to be such that particles and fields, acting in concert, can form causally efficacious real functional entities such as driveshafts and propellers. Similarly, surges of electrical and mechanical activity in appropriately designed material substrates, composed of particles and fields acting in concert, could implement, in the world of matter, complex functional structures and long sequences of logical operations. Thus it is conceivable that all of our behaviour, and all of the internal processing that occurs in our bodies and brains could be deduced, at least in principle, from the principles of classical mechanics and appropriate boundary conditions. -/- Contents: 1.

I examine a problem or dilemma of legitimation faced by the critical theorist who takes as the object of his or her critique a totality of which she or he is a part. The dilemma is that the theorist must either illegitimately exempt her critical theory from the determining influences of the totality or lose normative authority. The critics I examine in detail are: Adorno and Horkheimer; Kant; Hegel; feminist standpoint epistemologists, in particular, Sandra Harding; Irigaray; Foucault; and Arendt. ;I (...) conclude that a purely theoretical or epistemic ground for the legitimacy of totalizing critique is impossible; philosophical critique must involve an extra-rational faith or a political commitment. However, I also argue that the project of theoretical grounding should not be abandoned. I continue this project by drawing out of the critical theorists I examined some preliminary concepts and strategies that may, after further development, serve to provide a theory of the legitimacy of critical philosophy.

In lieu of an abstract, here is a brief excerpt of the content:138 HUME AND WITTGENSTEIN: CRITERIA VS. SKEPTICISM As far as philosophical admonitions go, there are probably few as famous as Wittgenstein's Blue Book warning: We are up against one of the great sources of philosophical bewilderment : we try to find a substance for a substantive, (p. 1) Wittgenstein, of course, could have added: This is something we should have learned long ago from Hume. He could have (...) quoted the following passage from the Appendix to the Treatise: Philosophers begin to be reconcil'd to the principle, that we have no idea of external substance, distinct from the ideas of particular qualities. This must pave the way for a like principle with regard to the mind, that we have no notion of it, distinct from the particular perceptions. Neither causal necessitation, self, nor substances could be located by Hume no matter how hard he tried to analyse his experience of the world. For Hume, there were no experiential 'facts-of-thematter ' in virtue of which one could acknowledge, with epistemic justification, causal connectivity or necessity, the temporal extension of one's own mind, or the elusive particularity of that in which qualities are sometimes said to inhere. We know that for Hume, since he tells us, his skepticism is engendered by his inability to surrender either of the two principles, the conjunction of which he takes to be impossible. He is unable to deny that whatever is distinguishable is separable, and, as well, that there are de re connections between what is distinguishable. (T 636) What this means for Hume is that the world 'as it really is' could well be utter- 139 Iy chaotic, or, at least, structured by relations and connections which bear no resemblance to the relations and connections imposed upon our perceptions and subsequently projected onto the world. Hume, of course, is neither the disputatious sort of ersatz skeptic at whom he sneers in the opening paragraphs of An Enquiry Concerning the Principles of Morals; nor is he a fainthearted skeptic, who will, in the end, return to us everything he had only seemed to take away. We know just how unrelenting he is in his attempt to show that "the understanding never observes any real connexion among objects, and that even the union of cause and effect, when strictly examin'd, resolves itself into a customary association of ideas." (T 259-260) Although Book I of the Treatise is called "Of the Understanding," misunderstanding is not a topic that exercises Hume. Of course, it is not all that difficult to understand why this is so. 'Misunderstanding ' is, on its semantic face, inseparably concerned with language; and a concern for and about language is not something that attracts very much of Hume's explicit attention. Indeed, I am inclined to think that Hume's most important explicit comment about language is to be found in Book II, where he notes:...the sense of interest has become common to all our fellows, and gives us a confidence of the future regularity of their conduct: And 'tis only on the expectation of this, that our moderation and abstinence are founded. In like manner are languages gradually establish'd by human conventions without any promise. (T 490) 140 In Wittgensteinian terms, I think that Hume is saying, in effect, that the conventions that determine what is just with respect to property in a society are, as it were, definitive of a form of social life; that is, not agreements, contracts, or compacts — promises, as Hume refers to these — since such compacts are themselves embedded in something deeper, namely, in the human conventions that ground such compacts and contracts. Although I am going beyond what Hume says here, there is no reason to believe that we cannot identify the analogical linguistic counterparts of promises and conventions. The linguistic conventions provide the foundational matrix for the applicability of the justifying truth-making procedures. In essence, sense precedes, and determines, truth conditions. What I will argue for here is the view that it is impossible for Wittgenstein to have been a skeptic of a Humean variety; since such skepticism presupposes realism; and, whatever else Wittgenstein is, or isn't, he is not...

The Theory of Important Criteria is used to argue that the age?old problem of the compatibility of free will and determinism turns on the question of the importance of causal indeterminacy of choice as a criterion of being able to do otherwise. One's answer to this question depends in turn on one's evaluation of certain moral issues and of the force and significance of certain similes, analogies and diagrams in terms of which one can ?depict? a deterministic universe. It (...) is further argued that the problem of free will and determinism is not a pseudo?problem, but a genuine problem that is hard to solve because of the depth and complexity of the evaluative issues on which it hangs.

It is readily conceded that “pain” is a term in a public language. But the concession leads us at once to speak of a criterion or criteria for its proper ascription; and the concept of a criterion of pain is a particularly difficult concept to lay bare. The issue has its classic source in Wittgenstein, where it extends far beyond the boundaries of mental entities. It is hard to say what Wittgenstein's view actually is regarding criteria; and it (...) may be more profitable to canvass certain untenable possibilities, with an eye to the problem, than to settle what can only be a question of a sort of archaeology.

The American Legal Realists, as I read them, are tacit legal positivists: they presuppose views about the criteria of legality that have affinities with positivist accounts of law in the sense that they employ primarily pedigree tests of legal validity. Ever since Ronald Dworkin's well-known critique of H.L.A. Hart's positivism a generation ago, however, it has been hotly contested whether there is anything about positivism as a legal theory that requires that tests of legal validity be pedigree tests. So-called (...) Soft or Inclusive versions of positivism are willing to relax the restrictions on the content of a Rule of Recognition to admit non-pedigree criteria of legal validity; Hard or Exclusive versons of positivism deny that such a move is compatible with the central commitments of positivism. Hard Positivism, of which Joseph Raz has been the leading proponent, thus competes with various Soft Positivisms, defended by, among others, Coleman, Lyons, Soper, Waluchow, and now, explicitly, Hart himself in the “Postscript.” If the Realists are positivists, as I claim, then it cannot be the case that Soft Positivism is a genuinely positivistic doctrine. But there is more at stake here than just labels. Realist arguments for the indeterminacy of law—arguments central to the whole Realist enterprise—depend crucially on their tacit Hard Positivism. If, in fact, positivism has a more relaxed view of the criteria of legality than Hard Positivism supposes, then Realist arguments depend on unsound tacit premises about legal validity. What is at stake, then, is not whether Realists should be called “Positivists” or merely “Hard Positivists,” but whether their underlying view of the criteria of legality is sound. It can only be so if the best arguments favor Hard Positivism. (shrink)

There has been much discussion in recent years regarding the date and authorship of the poems included in the Appendix Vergiliana, and about the Civis and the Culex in particular. Evidence of very various kinds has been brought to bear on the question. My chief aim in this paper is to propound a criterion which as far as I know is new—though it seems to me a fairly conspicuous thing, and I do not know why it has not been investigated (...) —and to examine certain criteria which seem to me to have been treated quite wrongly—treated in a way which could lead to no conclusion—even by so distinguished a scholar as Norden. I propose in a second paper to examine the argument from diction, especially in regard to the Culex, and to try to show that the evidence adduced for Virgilian authorship by Miss Jackson is not so conclusive as it has been supposed to be; and, next, to point out certain features or mannerisms in the Culex which seem to me to be on the whole against authorship by Virgil. I have hardly any doubt that both the Ciris and the Culex were written before 44 B.C., and the Lydia and Dirae only two or three years later; but, while the evidence for the early date of some of the Vergiliana grows stronger on further examination, the evidence for Virgilian authorship seems to me to grow weaker, even in the case of the well-attested Culex.

This paper presents a concept for pattern matching based on a parameter optimization system for approximative numerical calculation of some parameter combination under soft and hard constraints. The concept uses a non-linear parameter optimization method with an iterative variation of parameters. The paper focuses on the information modeling process to migrate problem-domain specific criteria into optimization-compatible objects suitable for a standardized parameter optimization procedure. A step-by-step transformation process is presented and implemented in object-oriented programming: classes and interfaces. The method (...) is applicable to a wide range of pattern-matching problems due to its flexibility and extensibility. (shrink)

This article provides a critical comparative analysis of the substantive and procedural values and ethical concepts articulated in guidelines for allocating scarce resources in the COVID-19 pandemic. We identified 21 local and national guidelines written in English, Spanish, German and French; applicable to specific and identifiable jurisdictions; and providing guidance to clinicians for decision making when allocating critical care resources during the COVID-19 pandemic. US guidelines were not included, as these had recently been reviewed elsewhere. Information was extracted from each (...) guideline on: 1) the development process; 2) the presence and nature of ethical, medical and social criteria for allocating critical care resources; and 3) the membership of and decision-making procedure of any triage committees. Results of our analysis show the majority appealed primarily to consequentialist reasoning in making allocation decisions, tempered by a largely pluralistic approach to other substantive and procedural values and ethical concepts. Medical and social criteria included medical need, co-morbidities, prognosis, age, disability and other factors, with a focus on seemingly objective medical criteria. There was little or no guidance on how to reconcile competing criteria, and little attention to internal contradictions within individual guidelines. Our analysis reveals the challenges in developing sound ethical guidance for allocating scarce medical resources, highlighting problems in operationalising ethical concepts and principles, divergence between guidelines, unresolved contradictions within the same guideline, and use of naïve objectivism in employing widely used medical criteria for allocating ICU resources.

Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We (...) argue that teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails. (shrink)

In decision-making based on multiple criteria, situations may arise where agents find their options to be neither better than, worse than nor equal to each other with respect to the relevant criteria. How, if at all, can a justified choice be made between such options? Are the options incomparable? This article explores a hypothetical case that illustrates how such a situation can arise in an environmental context; more specifically, it considers the deliberations of an imagined ‘ethics committee’ as (...) it struggles to decide whether or not a deep-sea mining project should be allowed to proceed. I argue that the case is best understood as involving options that are comparable in the sense of being ‘on a par’. Working out from a discussion of Ruth Chang's ‘self-governance’ theory of choice in cases of parity, I suggest that, in the environmental context, the idea of choices expressing a moral identity may lead us in the direction of a plausible solution to these particularly challenging cases.

BackgroundAssessing consciousness in other subjects, particularly in non-verbal and behaviourally disabled subjects (e.g., patients with disorders of consciousness), is notoriously challenging but increasingly urgent. The high rate of misdiagnosis among disorders of consciousness raises the need for new perspectives in order to inspire new technical and clinical approaches. Main bodyWe take as a starting point a recently introduced list of operational indicators of consciousness that facilitates its recognition in challenging cases like non-human animals and Artificial Intelligence to explore their relevance (...) to disorders of consciousness and their potential ethical impact on the diagnosis and healthcare of relevant patients. Indicators of consciousness mean particular capacities that can be deduced from observing the behaviour or cognitive performance of the subject in question (or from neural correlates of such performance) and that do not define a hard threshold in deciding about the presence of consciousness, but can be used to infer a graded measure based on the consistency amongst the different indicators. The indicators of consciousness under consideration offer a potential useful strategy for identifying and assessing residual consciousness in patients with disorders of consciousness, setting the theoretical stage for an operationalization and quantification of relevant brain activity.ConclusionsOur heuristic analysis supports the conclusion that the application of the identified indicators of consciousness to its disorders will likely inspire new strategies for assessing three very urgent issues: the misdiagnosis of disorders of consciousness; the need for a gold standard in detecting consciousness and diagnosing its disorders; and the need for a refined taxonomy of disorders of consciousness.

Gilles Deleuze has a growing readership in English philosophy, where for long he was eclipsed by brilliant contemporaries like Derrida and Foucault. It is good that we are coming to appreciate his highly original and fascinatingly intricate philosophy. He worked with integrity and genius to do something different in philosophy from everything he was hearing in contemporaries. None of the familiar labels—structuralism, poststructuralism, deconstruction, phenomenology, existentialism, hermeneutics—apply to him. One thing he shares with all of these movements, however, is a (...) conviction of Nietzsche’s importance, and his Nietzsche and Philosophy is second only to Heidegger in influencing how we understand Nietzsche’s accomplishment. The passion for Nietzsche sets Deleuze apart from another quasi-outsider whom he somewhat resembles—Alfred North Whitehead. Whitehead is another original, who wanted to do something new and different in philosophy, and not become mired in a polemic about “metaphysics” and whether it is finished. Shaviro thinks philosophy would be a lot different if Whitehead had enjoyed the attention the last century lavished on Heidegger and continues to lavish on Nietzsche. He epitomizes their difference in terms of their guiding question. Heidegger asks, What is the meaning of being? Whitehead asks, How is it that there is always something new? For Heidegger, metaphysics has always said the same, a monotonous litany of the names of Being. Whitehead is interested not in what metaphysics has always said, but what it has never yet said, even denied and rejected: the body, emotion, inconstancy, change, contingency, perspective. Deleuze writes appreciatively of Whitehead, but learns more from Bergson (whose current renaissance is largely his doing). Deleuze’s books are terrifically hard to read. There is nothing like them in our philosophical literature. He expects serious readers to struggle, and seems almost maliciously to exacerbate the encounter. Skeptics may wonder if it’s worth the trouble. Increasingly, though, an English readership is finding that it is. Shaviro’s book is more about Whitehead than Deleuze, but that is because he thinks that if we like Deleuze we should like Whitehead, too, and forget about Heidegger and Nietzsche. When he quotes Whitehead, saying “It is more important that a proposition be interesting than that it be true,” I wonder if he might not be half right. (shrink)

In today’s society, it becomes increasingly important to assess which non-human and non-verbal beings possess consciousness. This review article aims to delineate criteria for consciousness especially in animals, while also taking into account intelligent artifacts. First, we circumscribe what we mean with “consciousness” and describe key features of subjective experience: qualitative richness, situatedness, intentionality and interpretation, integration and the combination of dynamic and stabilizing properties. We argue that consciousness has a biological function, which is to present the subject with (...) a multimodal, situational survey of the surrounding world and body, subserving complex decision-making and goal-directed behavior. This survey reflects the brain’s capacity for internal modeling of external events underlying changes in sensory state. Next, we follow an inside-out approach: how can the features of conscious experience, correlating to mechanisms inside the brain, be logically coupled to externally observable properties? Instead of proposing criteria that would each define a “hard” threshold for consciousness, we outline six indicators: goal-directed behavior and model-based learning; anatomic and physiological substrates for generating integrative multimodal representations; psychometrics and meta-cognition; episodic memory; susceptibility to illusions and multistable perception; and specific visuospatial behaviors. Rather than emphasizing a particular indicator as being decisive, we propose that the consistency amongst these indicators can serve to assess consciousness in particular species. The integration of scores on the various indicators yields an overall, graded criterion for consciousness, somewhat comparable to the Glasgow Coma Scale for unresponsive patients. When considering theoretically derived measures of consciousness, it is argued that their validity should not be assessed on the basis of a single quantifiable measure, but requires cross-examination across multiple pieces of evidence, including the indicators proposed here. Current intelligent machines, including deep learning neural networks and agile robots, are not indicated to be conscious yet. Instead of assessing machine consciousness by a brief Turing-type of test, evidence for it may gradually accumulate when we study machines ethologically and across time, considering multiple behaviors that require flexibility, improvisation, spontaneous problem-solving and the situational conspectus typically associated with conscious experience.

[email protected] http://bruce.edmonds.name Abstract. Two kinds of problem are distinguished: the first of finding processes which produce complex outcomes from the interaction of simple parts, and the second of finding which process resulted in an observed complex outcome. The former I call the easy complexity problem and the later the hard complexity problem. It is often assumed that progress with the easy problem will aid process with the hard problem. However this assumes that the “reverse engineering” problem, of determining the process (...) from the outcomes is feasible. Taking a couple of simple models of reverse engineering, I show that this task is infeasible in the general case. Hence it cannot be assumed that reverse engineering is possible, and hence that most of the time progress on the easy problem will not help with the hard problem unless there are special properties of a particular set of processes that make it feasible. Assuming that complexity science is not merely an academic “game” and given the analysis of this paper, some criteria for the kinds of paper that have a reasonable chance of being eventually useful for understanding observed complex systems are outlined. Many complexity papers do not fare well against these critieria. (shrink)

How can laypeople justifiably distinguish between reliable experts and unreliable experts? This problem, usually called the 'problem of expert identification', is highly debated in recent social epistemology. A great amount of work has been undertaken in order to find satisfactory criteria for identifying experts in different branches of the empirical sciences, but hardly in the domain of moral knowledge. This asymmetry between social and moral epistemology is the motivation behind my paper. I reconsider the epistemological problem of identifying moral (...) experts by applying identification criteria developed in general social epistemology to the area of morality. As I will show, all of these criteria turn out to be inappropriate for identifying moral experts. This result seems implausible, because it conflicts with the observation that moral experts play an important role in public and scientific discourse, in ethics committees and boards. But this is not a real contradiction as I will illustrate by explaining which tasks these experts can, in my view, fulfill. (shrink)

Is disagreement about consciousness largely owed to no adequate initial clarification of the subject, to people in fact answering different questions clarified as actual consciousness. Philosophical method like the scientific method includes transition from the figurative to literal theory or analysis. A new theory will also satisfy various criteria not satisfied by many existing theories. The objective physical world has specifiable general characteristics including spatiality, lawfulness, being in science, connections with perception, and so on. Actualism, the literal theory or (...) analysis of actual consciousness, deriving mainly from the figurative database, is that actual consciousness has counterpart but partly different general characteristics. Actual consciousness is thus subjectively physical. So physicality in general consists in objective and also subjective physicality. Consciousness in the case of perception is only the dependent existence of a subjective external physical world out there, often a room. But cognitive and affective consciousness, various kinds of thinking and wanting, differently subjectively physical, is internal – subjectively physical representations-with-attitude, representations that also are actual. They differ from the representations that are lines of type, sounds etc. by being actual. Thus they involve a subjectivity or individuality that is a lawful unity. Actualism, both an externalism and an internalism, does not impose on consciousness a flat uniformuity, and it uniquely satisfies the various criteria for an adequate theory, including naturalism. Actual consciousness is a right subject and is a necessary part of any inquiry whatever into consciousness. All of it is a subject for more science, a workplace. There is no unique barrier or impediment whatever to science, as often said, no want of understanding of the mind-consciousness connection, no known unique hard problem of consciousness, no insuperable difficulty having to do with physicality and the history of science, no arguable ground at all of mysterianism.

We examine to what extent an adequate ontology of technical artefacts can be based on existing general accounts of the relation between higher-order objects and their material basis. We consider two of these accounts: supervenience and constitution. We take as our starting point the thesis that artefacts have a ‘dual nature’, that is, that they are both material bodies and functional objects. We present two criteria for an adequate ontology of artefacts, ‘Underdetermination’ and ‘Realizability Constraints’ , which address aspects (...) of the dual nature thesis. Assessing supervenience accounts, we find them either wanting with respect to these criteria or insufficiently informative. Next, we argue that a recent application of Lynne Rudder Baker’s constitution view to artefacts cannot meet our criteria, although the broader view leaves room for improvement. Based on our evaluation of the most promising candidates, we conclude that so far general metaphysical views fail to address the most salient features of artefacts. Although they can account for the fact that artefacts have a ‘dual nature’, they do not offer the conceptual resources needed to describe the relation between these natures; this relation raises a hard problem in metaphysics.Keywords: Metaphysics; Artefact; Supervenience; Constitution; Underdetermination.

The determination of death by neurological criteria—“brain death”—has long been legally established as death in all U.S. jurisdictions. Moreover, the consequences of determining brain death have been clear. Except for organ donation and in a few rare and narrow cases, clinicians withdraw physiological support shortly after determining brain death. Until recently, there has been almost zero action in U.S. legislatures, courts, or agencies either to eliminate or to change the legal status of brain death. Despite ongoing academic debates, the (...) law concerning brain death has remained stable for decades. However, since the Jahi McMath case in 2013, this legal certainty has been increasingly challenged. Over the past five years, more families have been emboldened to translate their concerns into legal claims challenging traditional brain death rules. While novel, these claims are not frivolous. Therefore, it is important to understand them so that we can address them most effectively. (shrink)

The goal of this paper is to see how mental and language representations are unique from a video-game perspective, using two main criteria. First, I will posit that the level of being both an interactive work of fiction and a self-involving interactive fiction belongs to a fuzzy interval and that some works – and, therefore, some video games – are more immersive than others. Second, I will observe how propositions tie the player’s representations of the real world and the (...) game world. Starting from psychological theories of pretense in children’s make-believe games, I will then expand Nichols and Stich’s cognitive theory of pretense to include an extra layer related to the game world, i.e., player-specific representations that govern player-specific propositions. The representations dealing with the work world are the socially shared ones, while the possible-world representations, dealing with most of the game world, are player-specific and tied to unique language use.

We have higher-order evidence that aesthetic judgements in the context of awarding art prizes may be affected by implicit bias, to the detriment of artists from marginalized groups. Epistemologists have suggested how to respond to higher-order evidence by appeal to bracketing or suspending judgement. We explain why these approaches do not help in this context. We turn to three ways of addressing the operation of implicit bias: (i) anonymization, (ii) the production of objective criteria, (iii) direct implicit bias mitigation (...) techniques. We show that, in the art prize case, strategy (i) is sometimes counterproductive and any benefits are partial, and strategy (ii) is difficult or impossible to implement. This means that the need for (iii) (direct implicit bias mitigation techniques) is more pressing here than elsewhere. The art prize context is one where mitigation of a particular kind is all we are left with. However, domain-specific problems arise for this strategy too, which call for further empirical work on the operation of implicit bias in the artworld. We conclude that the problem of implicit bias as it arises in the specific context of awarding prizes in the artworld is especially challenging and, given the unavailability of alternative mitigations in this context, the need for direct bias mitigation is even more pressing here than in society in general.

Should we grant rights to artificially intelligent robots? Most current and near-future robots do not meet the hard criteria set by deontological and utilitarian theory. Virtue ethics can avoid this problem with its indirect approach. However, both direct and indirect arguments for moral consideration rest on ontological features of entities, an approach which incurs several problems. In response to these difficulties, this paper taps into a different conceptual resource in order to be able to grant some degree of moral (...) consideration to some intelligent social robots: it sketches a novel argument for moral consideration based on social relations. It is shown that to further develop this argument we need to revise our existing ontological and social-political frameworks. It is suggested that we need a social ecology, which may be developed by engaging with Western ecology and Eastern worldviews. Although this relational turn raises many difficult issues and requires more work, this paper provides a rough outline of an alternative approach to moral consideration that can assist us in shaping our relations to intelligent robots and, by extension, to all artificial and biological entities that appear to us as more than instruments for our human purposes.

In this paper, we revisit the debate surrounding the Unfolding Argument (UA) against causal structure theories of consciousness (as well as the hard-criteria research program it prescribes), using it as a platform for discussing theoretical and methodological issues in consciousness research. Causal structure theories assert that consciousness depends on a particular causal structure of the brain. Our claim is that some of the assumptions fueling the UA are not warranted, and therefore we should reject the methodology for consciousness science (...) that the UA prescribes. First, we briefly survey the most popular philosophical positions in consciousness science, namely physicalism and functionalism. We discuss the relations between these positions and the behaviorist methodology that the UA assumptions express, despite the contrary claim of its proponents. Second, we argue that the same reasoning that the UA applies against causal structure theories can be applied to functionalist approaches, thus proving too much and deeming as unscientific a whole range of (non-causal structure) theories. Since this is overly restrictive and fits poorly with common practice in cognitive neuroscience, we suggest that the reasoning of the UA must be flawed. Third, we assess its philosophical assumptions, which express a restrictive methodology, and conclude that there are reasons to reject them. Finally, we propose a more inclusive methodology for consciousness science, that includes neural, behavioral, and phenomenological evidence (provided by the first-person perspective) without which consciousness science could not even start. Then, we extend this discussion to the scope of consciousness science, and conclude that theories of consciousness should be tested and evaluated on humans, and not on systems considerably different from us. Rather than restricting the methodology of consciousness science, we should, at this point, restrict the range of systems upon which it is supposed to be built. (shrink)

The hard-drinking, joke-cracking second-mate of Melville's Moby Dick doesn't receive much respect from critics.

The truly philosophical issue in machine conscioiusness is whether machines can have 'hard consciounsess'. Criteria for hard consciousness are higher than for phenomenal consciousness, since the latter incorporates first-person functional consciousness.

What role should age play in the allocation of organs for transplantation? Historically, older patients have not been listed as candidates for transplantation on the assumption that greater benefit could be obtained by favoring younger candidates, raising questions of equity and age discrimination. At the same time, organs offered for donation by the very old are frequently rejected because of concerns about length of viability. We examine a local case that challenges these practices: the liver from an elderly donor was (...) successfully transplanted into an older patient. After exploring some of the potential problems with such a solution, we propose creating a second pool of organs from the very old for transplantation into older candidates, thus expanding the number of organs available, saving additional lives, and including the elderly more visibly in our transplant system.

Are there objects that are “thin” in the sense that their existence does not make a substantial demand on the world? Frege famously thought so. He claimed that the equinumerosity of the knives and the forks suffices for there to be objects such as the number of knives and the number of forks, and for these objects to be identical. The idea of thin objects holds great philosophical promise but has proved hard to explicate. This book attempts to develop the (...) needed explanations by drawing on some Fregean ideas. First, to be an object is to be a possible referent of a singular term. Second, singular reference can be achieved by providing a criterion of identity for the would-be referent. The second idea enables a form of easy reference and thus, via the first idea, also a form of easy being. Paradox is avoided by imposing a predicativity restriction on the criteria of identity. But the abstraction based on a criterion of identity may result in an expanded domain. By iterating such expansions, a powerful account of dynamic abstraction is developed. (shrink)

Hume famously denied that he could experience the self. Most subsequent philosophers have concurred with this finding. I argue that if the subject is to function as a bearer of experience it must (1) lack sensory qualities in itself to be compatible with bearing sensory qualities and (2) be single so that it can unify experience. I use Douglas Harding’s first-person experiments to investigate the visual gap where one cannot see one’s own head. I argue that this open space conforms (...) to the above criteria and hence is consistent with being the subject. I respond to the objection that this location is merely a lack of visual experience. I argue that this space also encompasses sound and touch properties and hence functions as a bearer for other sensory modalities. These first-person findings provide prima facie support for the view that the subject is a thin bearer of experience. (shrink)

There are convincing counter-examples to the widely accepted thesis that we cannot believe at will. For it seems possible that the truth of a proposition depend on whether or not one believes it. I call such scenarios cases of Truth Depends on Belief and I argue that they meet the main criteria for believing at will that we find in the literature. I reply to five objections that one might level against the thesis that TDB cases show that believing (...) at will is possible, namely that mind-reading is impossible, in TDB cases, one's belief is caused by one's desire, in TDB scenarios, one chooses not a belief but something else, TDB cases are reducible to Feldman cases, and that if truth depends on belief, we are on the road to a regress. Of course, TDB scenarios hardly, if ever, occur in real life. For three reasons, they are nonetheless important. First, they show that the thesis that it is conceptually impossible to believe at will is simply false. Second, they provide us with an imp.. (shrink)

Algorithmic decision making is used in an increasing number of fields. Letting automated processes take decisions raises the question of their accountability. In the field of computational journalism, the algorithmic accountability framework proposed by Diakopoulos formalizes this challenge by considering algorithms as objects of human creation, with the goal of revealing the intent embedded into their implementation. A consequence of this definition is that ensuring accountability essentially boils down to a transparency question: given the appropriate reverse-engineering tools, it should be (...) feasible to extract design criteria and to identify intentional biases. General limitations of this transparency ideal have been discussed by Ananny and Crawford :973–989, 2018). We further focus on its technical limitations. We show that even if reverse-engineering concludes that the criteria embedded into an algorithm correspond to its publicized intent, it may be that adversarial behaviors make the algorithm deviate from its expected operation. We illustrate this issue with an automated news recommendation system, and show how the classification algorithms used in such systems can be fooled with hard-to-notice modifications of the articles to classify. We therefore suggest that robustness against adversarial behaviors should be taken into account in the definition of algorithmic accountability, to better capture the risks inherent to algorithmic decision making. We finally discuss the various challenges that this new technical limitation raises for journalism practice. (shrink)

This dissertation defends the reliability of first-person methods for studying consciousness, and applies first-person experiments to two philosophical problems: the experience of size and of the self. In chapter 1, I discuss the motivations for taking a first-person approach to consciousness, the background assumptions of the dissertation and some methodological preliminaries. In chapter 2, I address the claim that phenomenal judgements are far less reliable than perceptual judgements (Schwitzgebel, 2011). I argue that the main errors and limitations in making phenomenal (...) judgements are due to domain-general factors, which are shared in the formation of perceptual judgements. Phenomenal judgements may still be statistically less reliable than perceptual judgements, though I provide reasons for thinking that Schwitzgebel (2011) overstates the case for statistical unreliability. I also provide criteria for distinguishing between reliable and unreliable phenomenal judgements, hence defending phenomenal judgements against general introspective scepticism. Having identified the main errors in making phenomenal judgements, in chapter 3, I discuss how first-person experiments can be used to control for these errors. I provide examples, and discuss how they overcome attentional and conceptual errors, minimise biases, and exhibit high intersubjective reliability. In chapter 4, I investigate size experience. I use first-person experiments and empirical findings to argue that distant things looking smaller cannot be explained as an awareness of instantiated objective properties (visual angle or retinal image size). I also discuss how an awareness of uninstantiated objective properties cannot adequately account for the phenomenal character of size experience. This provides support for a subjectivist account of variance in size experience. In chapter 5, I investigate the sense of self. I distinguish between a weak sense of self (for-me-ness) and a strong sense of self in which there is a polarity between subject and object. I use first-person experiments from Douglas Harding to demonstrate an explicit strong sense of self, specifically when I point at where others see my face. I also argue that this sense of self is not explained by inference, thoughts, feelings, imagination nor the viewpoint. Rather, it is part of the structure of experience that I seem to be looking from here. Even if there is a sense of self, there may be no self. The question of chapter 6 is whether there can be a direct experience of the self. I argue that to function as a bearer of experience the subject must be single and lack sensory qualities in itself. I use Harding’s first-person experiments to investigate the visual gap where I cannot see my head. I argue that it conforms to the above criteria, and hence is a candidate for being the subject. This finding, in conjunction with the fact that I seem to be looking from the same location, provides prima facie evidence for the reality of the subject. I hold then that contrary to Hume and most philosophers since, that there can be a direct self-experience, if one knows which direction to attend. (shrink)

Fiction has been of concern to both the aesthetician and the ontologist. The former is concerned with the criteria or standards by which we judge the aesthetic worth of a fictional work, the latter with whether our ontology must be enlarged to include possible or imaginary worlds in which are housed the characters and incidents referred to and depicted in such works. This is a paper on the ontology of fiction. It will attempt to answer these ontological questions concerning (...) truth and reference in fiction by clarifying the use of language. Our paradigm case of the fictive use of language will be one in which the story-teller orally relates the fictional story in the presence of his audience, rather than one in which he inscribes his story so that it may be read at a later date. The value of considering the use of language in a face-to-face situation is that it brings before us in their full explicitness all of the different facets of a speech act, many of which often lie dormant in non-face-to-face uses and therefore are hard to discover from a consideration of such uses.

In late February and early March 2020, Italy became the European epicenter of the COVID-19 pandemic. Despite increasingly stringent containment measures enforced by the government, the health system faced an enormous pressure, and extraordinary efforts were made in order to increase overall hospital beds’ availability and especially ICU capacity. Nevertheless, the hardest-hit hospitals in Northern Italy experienced a shortage of ICU beds and resources that led to hard allocating choices. At the beginning of March 2020, the Italian Society of Anesthesia, (...) Analgesia, Resuscitation, and Intensive Care issued recommendations aimed at supporting physicians in prioritizing patients when the number of critically ill patients overwhelm the capacity of ICUs. One motivating concern for the SIAARTI guidance was that, if no balanced and consistent allocation procedures were applied to prioritize patients, there would be a concrete risk for unfair choices, and that the prevalent “first come, first served” principle would lead to many avoidable deaths. Among the drivers of decision for admission to ICUs, age, comorbidities, and preexisting functional status were included. The recommendations were criticized as ageist and potentially discriminatory against elderly patients. Looking forward to the next steps, the Italian experience can be relevant to other parts of the world that are yet to see a significant surge of COVID-19: the need for transparent triage criteria and commonly shared values give the Italian recommendations even greater legitimacy.

How consciousness appeared much earlier in evolutionary history than is commonly assumed, and why all vertebrates and perhaps even some invertebrates are conscious. How is consciousness created? When did it first appear on Earth, and how did it evolve? What constitutes consciousness, and which animals can be said to be sentient? In this book, Todd Feinberg and Jon Mallatt draw on recent scientific findings to answer these questions—and to tackle the most fundamental question about the nature of consciousness: how does (...) the material brain create subjective experience? After assembling a list of the biological and neurobiological features that seem responsible for consciousness, and considering the fossil record of evolution, Feinberg and Mallatt argue that consciousness appeared much earlier in evolutionary history than is commonly assumed. About 520 to 560 million years ago, they explain, the great “Cambrian explosion” of animal diversity produced the first complex brains, which were accompanied by the first appearance of consciousness; simple reflexive behaviors evolved into a unified inner world of subjective experiences. From this they deduce that all vertebrates are and have always been conscious—not just humans and other mammals, but also every fish, reptile, amphibian, and bird. Considering invertebrates, they find that arthropods (including insects and probably crustaceans) and cephalopods (including the octopus) meet many of the criteria for consciousness. The obvious and conventional wisdom–shattering implication is that consciousness evolved simultaneously but independently in the first vertebrates and possibly arthropods more than half a billion years ago. Combining evolutionary, neurobiological, and philosophical approaches allows Feinberg and Mallatt to offer an original solution to the “hard problem” of consciousness. (shrink)

Among discrete emotions, basic emotions are the most elemental; most distinct; most continuous across species, time, and place; and most intimately related to survival-critical functions. For an emotion to be afforded basic emotion status it must meet criteria of: (a) distinctness (primarily in behavioral and physiological characteristics), (b) hard-wiredness (circuitry built into the nervous system), and (c) functionality (provides a generalized solution to a particular survival-relevant challenge or opportunity). A set of six emotions that most clearly meet these (...) class='Hi'>criteria (enjoyment, anger, disgust, fear, surprise, sadness) and three additional emotions (relief/contentment, interest, love) for which the evidence is not yet quite as strong is described. Empirical approaches that are most and least useful for establishing basic-emotion status are discussed. Basic emotions are thought to have a central organizing mechanism and to have the capacity to influence behavior, thoughts, and other fundamental processes. (shrink)

Eugenio Bulygin is a distinguished representative of legal science and legal philosophy as they are known on the European continent - no accident, given the role of the civil law tradition in his home country, Argentina. Over the past half-century, Bulygin has engaged virtually all major legal philosophers in the English-speaking countries, including H.L.A. Hart, Ronald Dworkin, and Joseph Raz. Bulygin's essays, several written together with his eminent colleague and close friend Carlos E. Alchourrón, reflect the genre familiar from Alf (...) Ross's On Law and Justice, Hans Kelsen's Pure Theory of Law, and Georg Henrik von Wright's Norm and Action. Bulygin's wide-ranging interests include most of the topics found under the rubric of analytical jurisprudence - interpretation and judicial reasoning, validity and efficacy of law, legal positivism and the problem of normativity, completeness and consistency of the legal system, the nature of legal norms, and the role of deontic logic in the law. The reader will take delight in the often agreeably unorthodox character of Bulygin's views and in his hard-hitting arguments in defence of them. He challenges the received opinion on gaps in the law, on legal efficacy, on permissory norms, and on the criteria for legal validity. Bulygin's essays have been wellnigh inaccessible in the past, appearing in specialized journals, often in Spanish or German. They are now available for the first time in an English-language collection. (shrink)

A promising strategy for defending the role that representation plays in explanations of cognition frames the concept in terms of internal models or map‐like mechanisms. “Structural representation” offers an account of representation that is grounded in well‐specified, empirical criteria. However, anti‐representationalists continue to press the issue of how to account for the paradigmatic semantic properties of representation at the subpersonal level. In this paper, I offer an account of how the proponent of structural representation should think about content. There (...) are really two problems of content any account of representation must overcome: the “hard problem of content” and the “content determination problem.” I argue that the structural representation account has the resources to provide a naturalistically respectable notion of content that overcomes both problems.

Definition of the problemThe concept of privacy has been astonishingly absent in the discussion about dementia care. In general, questions of privacy receive a lot of attention in nursing ethics; however, when it comes to dementia care, hardly any systematic ethical debate on the topic can be found. It almost seems as though people with dementia had lost any comprehensible interest in privacy and no longer had any private sphere that needed to be considered or protected. However, this not only (...) contradicts widespread moral intuitions but also ignores the views and needs of those affected.ArgumentsWe first outline the origins and dimensions of the concept of privacy and point out problems and limitations in the context of dementia. Especially the prevalent liberal conceptions’ dependence on the idea of autonomy poses significant challenges to an adequate conceptualization of the moral significance of privacy for people with dementia. Therefore, we subsequently explore alternative ways of conceptualizing the “value of privacy” in the context of dementia care.ConclusionAutonomy-based concepts of privacy may still be valid in the early stages of dementia. However, in the further course of the syndrome, the relevance of other normative aspects comes to the fore, especially respect for remaining personal preferences as well as objective criteria of dignity and well-being. Thus, we outline in a differentiated manner how and to what extent privacy can be of normative importance beyond the purview of autonomy and should consequently be taken into consideration in dementia care.

With historical hindsight, it can be little questioned that the view of protozoa as unicellular organisms was important for the development of the discipline of protozoology. In the early years of this century, the assumption of unicellularity provided a sound justification for the study of protists: it linked them to the metazoa and supported the claim that the study of these “simple” unicellular organisms could shed light on the organization of the metazoan cell. This prospect was significant, given the state (...) of cytology circa 1910. In the wake of the major gains made in understanding nuclear division in the last two decades of the nineteenth century, cytology was suddenly confronted with many, seemingly less penetrable, problems. Several aspects of nuclear organization still remained unexplained, and recent research had revealed the presence in the cytoplasm of structures whose functions in cell life were unknown. Classical methods of cytology, relying on descriptive, morphological analysis, seemed ill equipped to resolve these questions.Hertwig's program for protozoology, grounded in the assumption of the fundamental unity of organization in protozoa and metazoa, offered a potential means for investigating these and other problems of cell theory. Linked to mainstream cytology, protozoology was advocated as a means of experimentally investigating key biolobical processes — reproduction, metabolism, and organelle morphology and physiology — less accessible in higher organisms. Protozoa were hailed as prime experimental organisms, in which cell structure and function could be more easily studied. Unlike the metazoan cell, they could be subjected to controlled experiments in which the external environment was modified and the effects monitored. Protozoa offered, in other words, a promising experimental means by which to investigate the cell — its structures and its processes.The success of this program within Germany was soon apparent. In contrast to the rather neglected state of the discipline in 1900, protozoology began to be recognized as more than a somewhat obscure area of study for specialists. In practical terms, this translated into greater numbers of students attracted to the field, increased institutional support for the discipline, and its elevation in status within the biological sciences as new developments, particularly in connection with medical applications, began to draw attention to the field.64The unicellular hypothesis also promoted the internal development of the science. It provided a rationale for introducing the various techniques used in cytology, embryology, physiology, and the new field of biochemistry as suitable research tools for protozoology as well. This vastly extended the research possibilities and facilitated the understanding of, among other things, protozoan organization, modes of reproduction, and evolutionary relationships. The new experimental grounding of the discipline in turn fitted in well with developments in biology at large: in contrast to the descriptive methodology that had predominated in the nineteenth century, this new experimental program placed protozoology at the forefront of the early twentieth-century movement to make biology an experimental science comparable to physics and chemistry.Yet the criticism of the unicellular hypothesis can also be seen as having served a valuable function within the development of the discipline. It focused attention on the study of protists as organisms in their own right, not simply as models for metazoan cells. More generally, it helped to remind biologists of the particular evolutionary assumptions that supported this conception. Dobell and other British critics pointed out, among other things, the association between the theory of recapitulation and the interpretation of protozoa as unicellular organisms. At the time when the recapitulation theory and the germ-layer doctrine were in decline, it was important to stress how these evolutionary ideas also entered into the contemporary concepts of subsidiary specialties. This was as true for protozoology as it was for cell theory itself. The chromidial theory, in its various guises, and the binuclearity hypothesis did in fact contain elements of recapitulationist reasoning, and they were open to criticism for the same kind of overly speculative theorizing that characterized this evolution theory. Dobell's critique forced protozoologists and cell theorists alike to review the theoretical postulates guiding their investigations.In the absence of further historical studies, it is hard to evaluate the consequences of this debate in later years. The issue was not whether protozoa were the precursors of metazoa — both sides accepted this. They disagreed over which particular protozoon had served as the ancestral form, and this, in turn, influenced their stance on the question of unicellularity. The situation is little changed today. Because the former question is still an open one, the latter remains so too. Both of the models for the origin of multicellular organisms — colonies of ciliates versus multinucleate protists — are still presented as possible mechanisms in modern textbooks of evolution. Unable to judge the dispute in terms of the ultimate validity of the competing conceptions, the historian requires other criteria. It perhaps becomes more important to evaluate the issues in the context of the internal and external stimulus they provided the discipline.65 In these terms, and from the present historical vantage point, Hertwig's research program for protozoology, based upon the unicellular hypothesis, appears to have been a successful one.

In the Netherlands, in 2002, euthanasia became a legitimate medical act, only allowed when the due care criteria and procedural requirements are met. Legally, an Advanced Euthanasia Directive can replace direct communication if a patient can no longer express his own wishes. In the past decade, an exponential number of persons with dementia share a euthanasia request with their physician. The impact this on physicians, and the consequent support needs, remained unknown. Our objective was to gain more insight into (...) the experiences and needs of Dutch general practitioners and elderly care physicians when handling a euthanasia request from a person with dementia. We performed a qualitative interview study. Participants were recruited via purposive sampling. The interviews were transcribed verbatim, and analyzed using the conventional thematic content analysis. Eleven general practitioners and elderly care physicians with a variety of experience and different attitudes towards euthanasia for PWD were included. Euthanasia requests appeared to have a major impact on physicians. Difficulties they experienced were related to timing, workload, pressure from and expectations of relatives, society’s negative view of dementia in combination with the ‘right to die’ view, the interpretation of the law and AEDs, ethical considerations, and communication with PWD and relatives. To deal with these difficulties, participants need support from colleagues and other professionals. Although elderly care physicians appreciated moral deliberation and support by chaplains, this was hardly mentioned by GPs. Euthanasia requests in dementia seem to place an ethically and emotionally heavy burden on Dutch GPs and elderly care physicians. The awareness of, and access to, existing and new support mechanisms needs further exploration. (shrink)

A central strand in philosophical debate over the just distribution of resources attempts to juggle three competing imperatives: helping those who are worst off, helping those who will benefit the most, and then – beyond this – determining when to aggregate such ‘worst off’ and ‘benefit’ claims, and when instead to treat no such claim as greater than that which any individual by herself can exert. Yet as various philosophers have observed, ‘we have no satisfactory theoretical characterization’ as to how (...) to weigh each of the three imperatives against one another, we find it ‘difficult to state... precise or comprehensive conclusions’, and we do not yet have a ‘metric for integrating the three measures’. In what follows, I offer an approach to weighing the three criteria against one another that yields resolutions – in Hard Cases of the ‘saving one infant's life versus replacing ten elderly people's hips’ sort – that are cardinally definitive, intuitively satisfactory and theoretically justified.

Localization Wireless Sensor Networks (WSN) represent a research topic with increasing interest due to their numerous applications. However, the viability of these systems is compromised by the attained localization uncertainties once implemented, since the network performance is highly dependent on the sensors location. The Node Location Problem (NLP) aims to obtain the optimal distribution of sensors for a particular environment, a problem already categorized as NP-Hard. Furthermore, localization WSN usually perform a sensor selection for determining which nodes are to be (...) utilized for maximizing the achieved accuracy. This problem, defined as the Sensor Selection Problem (SSP), has also been categorized as NP-Hard. While different metaheuristics have been proposed for attaining a near optimal solution in both problems, no approach has considered the two problems simultaneously, thus resulting in suboptimal solutions since the SSP is biased by the actual node distribution once deployed. In this paper, a combined approach of both problems simultaneously is proposed, thus considering the SSP within the NLP. Furthermore, a novel metaheuristic combining the Black Widow Optimization (BWO) algorithm and the Variable Neighbourhood Descent Chains (VND-Chains) local search, denominated as BWO-VND-Chains, is particularly devised for the first time in the author’s best knowledge for the NLP, resulting in a more efficient and robust optimization technique. Finally, a comparison of different metaheuristic algorithms is proposed over an actual urban scenario, considering different sensor selection criteria in order to attain the best methodology and selection technique. Results show that the newly devised algorithm with the SSP criteria optimization achieves mean localization uncertainties up to 19.66 % lower than traditional methodologies. (shrink)

During the last decade new developments in theoretical and speculative cosmology have reopened the old discussion of cosmology’s scientific status and the more general question of the demarcation between science and non-science. The multiverse hypothesis, in particular, is central to this discussion and controversial because it seems to disagree with methodological and epistemic standards traditionally accepted in the physical sciences. But what are these standards and how sacrosanct are they? Does anthropic multiverse cosmology rest on evaluation criteria that conflict (...) with and go beyond those ordinarily accepted, so that it constitutes an “epistemic shift” in fundamental physics? The paper offers a brief characterization of the modern multiverse and also refers to a few earlier attempts to introduce epistemic shifts in the science of the universe. It further discusses the several meanings of testability, addresses the question of falsifiability as a sine qua non for a theory being scientific, and briefly compares the situation in cosmology with the one in systematic biology. Multiverse theory is not generally falsifiable, which has led to proposals from some physicists to overrule not only Popperian standards but also other evaluation criteria of a philosophical nature. However, this is hardly possible and nor is it possible to get rid of explicit philosophical considerations in some other aspects of cosmological research, however advanced it becomes. (shrink)
