What considerations place genuine constraints on an adequate semantics for normative and evaluative expressions? Linguists recognize facts about ordinary uses of such expressions and competent speakers’ judgments about which uses are appropriate. The contemporary literature reflects the widespread assumption that linguists don’t rely upon an additional source of data—competent speakers’ judgments about possible disagreement with hypothetical speech communities. We have several good reasons to think that such judgments are not probative for semantic theorizing. Therefore, we should accord these judgments no (...) probative value for the development of a semantics for our moral terms. Such judgments can no longer be presumed to put pressure on theories according to which our moral expressions share a semantics with ordinary, descriptive terms. Many rivals to pure, Descriptivist theories count among their advantages the ability to accommodate these judgments. If these judgments have no probative value, such theories lose an important source of support. (shrink)

Background: The concept of digital twins has great potential for transforming the existing health care system by making it more personalized. As a convergence of health care, artificial intelligence, and information and communication technologies, personalized health care services that are developed under the concept of digital twins raise a myriad of ethical issues. Although some of the ethical issues are known to researchers working on digital health and personalized medicine, currently, there is no comprehensive review that maps the major ethical (...) risks of digital twins for personalized health care services. Objective: This study aims to fill the research gap by identifying the major ethical risks of digital twins for personalized health care services. We first propose a working definition for digital twins for personalized health care services to facilitate future discussions on the ethical issues related to these emerging digital health services. We then develop a process-oriented ethical map to identify the major ethical risks in each of the different data processing phases. Methods: We resorted to the literature on eHealth, personalized medicine, precision medicine, and information engineering to identify potential issues and developed a process-oriented ethical map to structure the inquiry in a more systematic way. The ethical map allows us to see how each of the major ethical concerns emerges during the process of transforming raw data into valuable information. Developers of a digital twin for personalized health care service may use this map to identify ethical risks during the development stage in a more systematic way and can proactively address them. Results: This paper provides a working definition of digital twins for personalized health care services by identifying 3 features that distinguish the new application from other eHealth services. On the basis of the working definition, this paper further layouts 10 major operational problems and the corresponding ethical risks. Conclusions: It is challenging to address all the major ethical risks that a digital twin for a personalized health care service might encounter proactively without a conceptual map at hand. The process-oriented ethical map we propose here can assist the developers of digital twins for personalized health care services in analyzing ethical risks in a more systematic manner. (shrink)

In this paper, I explore several versions of the bundle theory and the substratum theory and compare them, with the surprising result that it seems to be true that they are equivalent (in a sense of 'equivalent' to be specified). In order to see whether this is correct or not, I go through several steps : first, I examine different versions of the bundle theory with tropes and compare them to the substratum theory with tropes by going through various standard (...) objections and arguing for a tu quoque in all cases. Emphasizing the theoretical role of the substratum and of the relation of compresence, I defend the claim that these views are equivalent for all theoretical purposes. I then examine two different versions of the bundle theory with universals, and show that one of them is, here again, equivalent to the substratum theory with universals, by examining how both views face the famous objection from Identity of Indiscernibles in a completely parallel way. It is only the second, quite extreme and puzzling, version of the bundle theory with universals that is not be equivalent to any other view; and the diagnosis of why this is so will show just how unpalatable the view is. Similarly, only a not-so-palatable version of the substratum theory is genuinely different from the other views; and here again it's precisely what makes it different that makes it less appealing.

Sven Bernecker’s contribution to the ongoing revival in the philosophy of memory offers a consistent vision and analysis of propositional remembering, and covers a range of topics in analytic metaphysics and epistemology. Bernecker defends a methodological externalism, by which memory ‘must be analyzed from a third-person point of view’ (34): so even though conceptual analysis remains the primary method, the ‘linguistic intuitions’ that guide it ‘are not a priori but empirical working hypotheses’ (31). Given the central role of such intuitions (...) in Bernecker’s treatment of many briefly described thought experiments throughout the book, it is strange that he does not defend their use more explicitly in this early section on method, instead leaving it to a later footnote (147, n. 11) to say that ‘trying to defend the use of intuitions in the philosophy of memory would . . . take us too far afield’. Bernecker’s subtitle signals a restricted target audience: this is a book for those analytic philosophers who will enjoy long exegeses on Twin Earth, slow switching or quasi-memory. Psychological results on memory are cited, but only piecemeal, and interactive dialogue with scientific theory is not Bernecker’s aim. (shrink)

This chapter is particularly concerned with the status of history, dance history especially, within Dance Studies. It asks what has befallen the more recent status of history, once an epistemological support at a critical stage in Dance Studies’s early development, now that Dance Studies is better established, relatively speaking, within the academy. Is history so much scaffolding which, having fulfilled its purpose in enabling the disciplinary plant to take root, is to be dismantled and, if not actually discarded, at least (...) demoted? Three factors will be identified and proposed as having particular significance in this connection, imbuing this chapter with a tri-partite structure. The first concerns the already noted strong imprint of Cultural Studies on Dance Studies and the possible bearing of this imprint on dance history’s status within Dance Studies. For the particular manner in which Dance Studies has construed Cultural Studies may, this chapter will suggest, have impacted upon dance history’s standing within communities of dance scholarship. The second factor has to do with the implications, for dance history, of a particular critique based in a branch of dance scholarship, that perceives phenomenology, which it deems a good fit for dance inquiry, as inherently antithetical to history. In particular, this critique takes the work of Michel Foucault - which it identifies closely with, and as, historical practice - as incompatible with dance enquiry. Incompatibility is staked on the twin grounds of Foucault’s break with, and supposed resulting and enduring antipathy towards, phenomenology; and his perceived embrace of history which is, itself, also understood to result from such a break. In effect, then, this critique questions the very suitability, for dance research, of approaches based in history-focussed inquiry. The ability to call this critique into question, in the ways that the present discussion, in seeking to rehabilitate Foucault, and so history, needs to demonstrate, constitutes the third factor. This final factor makes two particular, further demands of this chapter. Namely that the interrelated questions of Foucault, phenomenology, and dance; and of the position which phenomenology has itself adopted in relation to history, be re-visited and re-evaluated to the extent that space reasonably allows. Fortunately, these interrelated questions are ones which have - relatively recently - preoccupied scholarship on Foucault, and on phenomenology, respectively. This preoccupation may in and of itself be one possible indicator that there is indeed more at stake, and so to consider, regarding both questions, than the lines drawn by the aforementioned critique might suggest.

Can heritability estimates provide causal information? This paper argues for an affirmative answer: since a non-nil heritability estimate satisfies certain characteristic properties of causation (i.e., association, manipulability, and counterfactual dependence), it increases the probability that the relation between genotypic variance and phenotypic variance is (at least partly) causal. Contrary to earlier proposals in the literature, the argument does not assume the correctness of any particular conception of the nature of causation, rather focusing on properties that are characteristic of causal relationships. (...) The argument is defended against Lewontin's (1974) locality objection and Kaplan and Turkheimer's (2021) recent critique of Genome-Wide Association Studies (GWAS). (shrink)

This is an excellent review of gene/environment interactions on behavior and, in spite of being a bit dated, is an easy and worthwhile read. They start with twin studies which show the overwhelming impact of genetics on behavior. They note the increasingly well known studies of Judith Harris which extend and summarize the facts that shared home environment has almost no effect on behavior and that adopted children grow up to be as different from their stepbrothers and sisters as (...) people chosen at random. One basic point that they (and nearly all who discuss behavioral genetics) fail to note is that the hundreds (thousands depending on your viewpoint) of human behavioral universals, including all the basics of our personalities, are 100% determined by our genes, with no variation in normals. Everyone sees a tree as a tree and not a stone, seeks and eats food, gets angry and jealous etc. So, what they are mostly talking about here is how much environment (culture) can affect the degree to which various traits are shown, rather than their appearance. Finally, they discuss eugenics in the usual politically correct fashion, failing to note that we and all organisms are the products of nature’s eugenics and that attempts to defeat natural selection with medicine, agriculture, and civilization as a whole, are disastrous for any society that persists. As much as 50% of all conceptions, or some 100 million/year, end in early spontaneous abortion, nearly all without the mother being aware. This natural culling of defective genes drives evolution, keeps us relatively genetically sound and makes society possible. However, it is now clear that overpopulation will destroy the world before dysgenics has a chance. -/- Those wishing a comprehensive up to date account of Wittgenstein, Searle and their analysis of behavior from the modern two systems view may consult my article The Logical Structure of Philosophy, Psychology, Mind and Language as Revealed in Wittgenstein and Searle (2016).

The aim of this paper is to assess the relationship between anti-physicalist arguments in the philosophy of mind and anti-naturalist arguments in metaethics, and to show how the literature on the mind-body problem can inform metaethics. Among the questions we will consider are: (1) whether a moral parallel of the knowledge argument can be constructed to create trouble for naturalists, (2) the relationship between such a "Moral Knowledge Argument" and the familiar Open Question Argument, and (3) how naturalists can respond (...) to the Moral Twin Earth argument. We will give particular attention to recent arguments in the philosophy of mind that aim to show that anti-physicalist arguments can be defused by acknowledging a distinctive kind of conceptual dualism between the phenomenal and the physical. This tactic for evading anti-physicalist arguments has come to be known as the Phenomenal Concept Strategy. We will propose a metaethical version of this strategy, which we shall call the `Moral Concept Strategy'. We suggest that the Moral Concept Strategy offers the most promising way out of these anti-naturalist arguments, though significant challenges remain. (shrink)

This study seeks to critically explore the link between sovereignty, violence and war in Giorgio Agamben’s Homo Sacer series and Thomas Hobbes’s Leviathan. From a brief rereading of Leviathan’s main arguments that explicitly revolves around the Aristotelian distinction between actuality/ potentiality, it will conclude that Hobbesian pre-contractual violence is primarily based on what Hobbes terms “anticipatory reason” and the problem of future contingency. Relying on Foucauldian insights, it will be emphasized that the assumption of certain potentialities suffices in leading (...) to Hobbes’s well-known conclusion that the state of nature is a “condition of Warre.” In a second step, this study considers some of Agamben’s arguments to account for how pre-contractual violence as envisioned by Hobbes cannot be rendered impotent through the integration of a sovereign. In specific, Agamben’s claims shed light on an irreducible, inextricable entwining between the state of nature and the state of law as “Siamese twins” (Virno). On a meta-level, Agamben thus implicitly shows how the “Hobbesian problem” cannot be merely reduced to a “problem of order” (Parsons). With regard to the current functioning of the stratagems of financial markets and the mechanisms of future-colonization underpinning global politics, this study finally argues that Hobbes ought to be reevaluated in particular regarding the problem of the future in his account. Partly responding to Agamben’s critical investigations, I suggest that a careful exploration of what will be coined “the prospects of an actualization of the potentiality not-to-be” might serve as a first theoretical step towards a productive form of criticism.

This paper is a study of a distinctively chemical notion of possibility. This is the notion of possibility that occurs in chemical discourses when chemists speak of the possibility or impossibility of achieving a given result through chemical means. This notion pertains to the possibility of processes, not of compounds, so it differs from the kind of chemical possibility mentioned in Wittgenstein's Philosophical Investigations or the kinds discussed in the literature on Putnam's Twin Earth argument. I argue that (...) this process-oriented notion of possibility cannot be reduced in a simple way to physical possibility, and that standard possible worlds semantics does not allow a natural analysis of this notion. I suggest an extension of possible worlds semantics that may overcome this limitation. I finish by pointing out some open questions about chemical possibility. (shrink)

Many philosophers claim that interesting forms of epistemic evaluation are insensitive to truth in a very specific way. Suppose that two possible agents believe the same proposition based on the same evidence. Either both are justified or neither is; either both have good evidence for holding the belief or neither does. This does not change if, on this particular occasion, it turns out that only one of the two agents has a true belief. Epitomizing this line of thought are thought (...) experiments about radically deceived “brains in vats.” It is widely and uncritically assumed that such a brain is equally justified as its normally embodied human “twin.” This “parity” intuition is the heart of truth-insensitive theories of core epistemological properties such as justification and rationality. Rejecting the parity intuition is considered radical and revisionist. In this paper, I show that exactly the opposite is true. The parity intuition is idiosyncratic and widely rejected. A brain in a vat is not justified and has worse evidence than its normally embodied counterpart. On nearly every ordinary way of evaluating beliefs, a false belief is significantly inferior to a true belief. Of all the evaluations studied here, only blamelessness is truth-insensitive. (shrink)

The goal of this article is twofold. First, it revises the historiographic partition proposed by John Deely in Four Ages of Understanding (2001) by arguing that the moment marking the beginning of philosophical Modernity has been vividly recorded in Descartes’ Meditations on First Philosophy with the experiment with the wax. Second, an upshot of this historical study is that it helps make sense of Deely’s somewhat iconoclastic use of the words “subject” and “subjectivity” to designate mind-independent worldly things. The (...) hope is that successfully accomplishing these twin tasks will give semiotic inquiry a better appreciation of its own history, as well as resources genial to furthering its ongoing development.

Behavioral genetic (BG) research has yielded many important discoveries about the origins of human behavior, but offers little insight into how we might improve outcomes. We posit that this gap in our knowledge base stems in part from the epidemiologic nature of BG research questions. Namely, BG studies focus on understanding etiology as it currently exists, rather than etiology in environments that could exist but do not as of yet (e.g., etiology following an intervention). Put another way, they focus exclusively (...) on the etiology of “what is” rather than “what could be”. The current paper discusses various aspects of this field-wide methodological reality, and offers a way to overcome it by demonstrating how behavioral geneticists can incorporate an experimental approach into their work. We outline an ongoing study that embeds a randomized intervention within a twin design, connecting “what is” and “what could be” for the first time. We then lay out a more general framework for a new field—experimental BGs—which has the potential to advance both scientific inquiry and related philosophical discussions. (shrink)

Two of the staunchest critics of astrology presented their case in an article published in this journal that has since become a standard reference. The authors argue that the astrological experience is more likely to work by 'hidden persuaders' than by either objective or psychic criteria, yet their argument provides no evidence of this. The authors demand careful testing yet their own examples and claims against astrology are not careful. The metaanalysis claim mixes studies with widely disparate data types. The (...) parental tampering argument against Michel Gauquelin's planetary eminence findings lacks supportive evidence. The 'definitive' time twins test fails to define the criteria of resemblance. The test of predicting psychological test profiles does not discriminate between permanent personality dimensions and psychological states as astrology requires. The blind chart matching studies evaluated skills on the wrong parties where they would not be expected by either astrology or psychology. The authors fail to mention the most interesting and promising peer-reviewed astrological research studies that were available to them. Improved discourse with astrological subject matter experts is recommended. (shrink)

Considering the propositions of the virtual universe with its short history, there are digital twins and various economic investments. While the Metaverse points out a novel universe, it is able to promise much more than producing a copy of the self and imitation of conventional economic interactions. To reveal these potentials, it is necessary to determine the areas that must be meticulously focused on. Although Metaverse has permeated daily life dialogues, studies in the academic field are limited. Likewise, research about (...) its architecture and space needs to be developed in this area. No matter how far the new universe propositions go, they still stick with the quantitative values of the physical world. This issue obstructs the creation of its own reality. However, the universe's own digitalized digitalised structure does not require that the imagination of the spaces stuck with a quantitative basis. To avoid quantitative and reductive attitudes, focusing on the atmosphere of this universe may be a solution. The study aims to collide the possibilities of the Metaverse and the architectural atmosphere discussions to make an alternative reading of the Metaverse. Developing theories about the atmosphere of spaces and conducting atmospheric studies about Metaverse allow us to develop meta-experiences of the Metaverse. Focusing on the architectural atmosphere, immediate appreciation, ecstatic being and hallucinatory image will deepen the definition of Metaverse and provide a multi-layered experience. The image of the atmosphere and ecstatic being is associated with a ‘hallucinatory image'. The hallucinatory image has a structure that does not narrow down its references to the physical world. With this aspect, it may provide forms of alternative perceptions specific to the Metaverse. The hallucinatory image, parallel with the sensation of an ecstatic being, stimulates us to sense the atmosphere produced by the Metaverse. (shrink)

One type of deflationism about metaphysical modality suggests that it can be analysed strictly in terms of linguistic or conceptual content and that there is nothing particularly metaphysical about modality. Scott Soames is explicitly opposed to this trend. However, a detailed study of Soames’s own account of modality reveals that it has striking similarities with the deflationary account. In this paper I will compare Soames’s account of a posteriori necessities concerning natural kinds with the deflationary one, specifically Alan Sidelle’s (...) account, and suggest that Soames’s account is vulnerable to the deflationist’s critique. Furthermore, I conjecture that both the deflationary account and Soames’s account fail to fully explicate the metaphysical content of a posteriori necessities. Although I will focus on Soames, my argument may have more general implications towards the prospects of providing a meaning-based account of metaphysical modality. (shrink)

The paper discusses the possibility of constructing economic models using the methodology of model construction in classical mechanics. At the same time, unlike the "econophysical" approach, the properties of economic models are derived without involvement of any equivalent physical properties, but with account of the types of symmetry existing in the economic system. It has been shown that at this approach practically all known mechanical variables have their "economic twins". The variational principle is formulated on the basis of formal mathematical (...) construction without involving the subjective factor common to the majority of models in economics. The dynamics of interaction of two companies has been studies in details, on the basis of which we can proceed to modeling of more complex and realistic economic systems. Prediction of the possibility of constructing economic theory on the basis of primary principles analogously to physics has been made. (shrink)

Content externalism is the dominant view in the philosophy of mind. Content essentialism, the thesis that thought tokens have their contents essentially, is also popular. And many externalists are supporters of such essentialism. However, endorsing the conjunction of those views either (i) commits one to a counterintuitive view of the underlying physical nature of thought tokens or (ii) commits one to a slightly different but still counterintuitive view of the relation of thought tokens to physical tokens as well as a (...) rejection of realist physicalism. In this essay I reveal the problem and articulate and adjudicate among the possible solutions. I will end up rejecting content essentialism. (shrink)

In War & Ethics, Nicholas Fotion undertakes three main tasks. The first is critical: to analyze ‘Just War Theory’ (JWT) in the evolving context of modern warfare between nations and non-nation groups, using various case studies to illustrate the strengths and weaknesses of the theory. The second task is modification: to construct a new Just War Theory to incorporate wars between nations (JWT-Regular) and wars between nations and non-nation groups (JWT-Irregular). The third and final task is defensive: to show that (...) Just War Theory in general, and the twin theory in particular, are useful tools in assessing when a war is just. (shrink)

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error.

Fetal reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or singleton pregnancy. Use of assisted reproductive technologies increases the likelihood of multiple pregnancies, and many fetal reductions are done after in vitro fertilisation and embryo transfer, either because of social or health-related reasons. In this paper, I apply Joe Horton’s all or nothing problem to the ethics of fetal reduction in the case of a twin pregnancy. (...) I argue that in the case of a twin pregnancy, there are two intuitively plausible claims: abortion is morally permissible, and it is morally wrong to abort just one of the fetuses. But since we should choose morally permissible acts rather than impermissible ones, the two claims lead to another highly implausible claim: the woman ought to abort both fetuses rather than only one. Yet, this does not seem right. A plausible moral theory cannot advocate such a pro-death view. Or can it? I suggest ways to solve this problem and draw implications for each solution. There are no data in this work. (shrink)

It is widely held that introspection-based self-ascriptions of mental states are immune to error through misidentification , relative to the first person pronoun. Many have taken such errors to be logically impossible, arguing that the immunity holds as an “absolute” necessity. Here I discuss an actual case of craniopagus twins—twins conjoined at the head and brain—as a means to arguing that such errors are logically possible and, for all we know, nomologically possible. An important feature of the example is that (...) it is one where a person may be said to be introspectively aware of a mental state that occurs outside of her own mind. Implications are discussed for views of the relation between introspection and mental state ownership, and between introspection and epistemic criteria for the “mark of the mental.”. (shrink)

A previously unrecognised argument against deterministic chance is introduced. The argument rests on the twin ideas that determined outcomes are settled, while chancy outcomes are unsettled, thus making cases of determined but chancy outcomes impossible. Closer attention to tacit assumptions about settledness makes available some principled lines of resistance to the argument for compatibilists about chance and determinism. Yet the costs of maintaining compatibilism may be higher with respect to this argument than with respect to existing incompatibilist arguments.

Horgan and Timmons have argued that our intuitions about the semantics of non-moral language and moral language differ, and that while twin-earth semantic intuitions generate one result in Putnam´s twater case, moral twin-earth fails to generate comparable results for moral terms. Horgan and Timmon´s conclude from this that the semantic norms governing the use of natural kind terms differ from the semantic norms governing the use of moral terms. I will argue that Horgan and Timmons’ intuitive moral (...) class='Hi'>twin-earth argument fails to derail the new moral realism. Further, I will discuss Boyd’s semantic theory and raise problems for it that do not rely on the use of moral twin-earth. (shrink)

In a recent paper in this journal, McCall and Lowe (2003) argue that an understanding of Special Relativity reveals that the A theorist’s notion of temporal passage is consistent with the B theory of time. They arrive at this conclusion by considering the twins’ paradox, where one of two twins (T) travels to Alpha Centauri and back and upon her return has aged 30 years, while her earth-bound twin (S) has aged 40 years. This paper argues that their account (...) of temporal passage fails to reconcile the A theoretic notion of temporal passage with the B theory of time since the B theorist is at liberty to adopt this as an account of temporal passage as understood by the B theorist.

Horgan and Timmons, with their Moral Twin Earth arguments, argue that the new moral realism falls prey to either objectionable relativism or referential indeterminacy. The Moral Twin Earth thought experiment on which the arguments are based relies in crucial ways on the use of intuitions. First, it builds on Putnam’s well-known Twin Earth example and the conclusions drawn from that about the meaning of kind names. Further, it relies on the intuition that were Earthers and Twin (...) Earthers to meet, they would be able to have genuine moral disagreements. I will argue that the similarities with Putnam’s thought experiment are questionable and so the reliance on Putnam-like intuitions is questionable. I will then further argue that even if we accept the intuitions that Horgan and Timmons rely on, the anti-realist conclusion is not warranted due to there being more to the meaning of kind terms than the argument assumes. Once we develop the meaning of kind terms further we can acknowledge both that Earthers and Twin Earthers refer to different properties with their moral terms, and that in spite of that they can have a substantive disagreement due to a shared meaning component.

In this paper I argue against Twin-Earth externalism. The mistake that Twin Earth arguments rest on is the failure to appreciate the force of the following dilemma. Some features of things around us do matter for the purposes of conceptual classification, and others do not. The most plausible way to draw this distinction is to see whether a certain feature enters the cognitive perspective of the experiencing subject in relation to the kind in question or not. If it (...) does, we can trace conceptual differences to internal differences. If it doesn’t, we do not have a case of conceptual difference. Neither case supports Twin Earth externalism. (shrink)

In special cases of partial twinning, two heads, each supporting a more-orless normal human mental life, emerge from a single torso. It is often argued that there must be two people in such a case, even if there is only one biological organism. That would pose a problem for ‘animalism’, the view that people are organisms. The paper argues that it is very hard to say what sort of non-organisms the people in such cases would be. Reflection on partial twinning (...) is no more comfortable for those who think we’re not organisms than for those who think we are. We may have to accept that a single person could have two separate mental lives. (shrink)

Mark Timmons and Terry Horgan have argued that the new moral realism, which rests on the causal theory of reference, is untenable. While I do agree that the new moral realism is untenable, I do not think that Timmons and Horgan have succeeded in showing that it is. I will lay out the case for new moral realism and Horgan and Timmons’ argument against it, and then argue that their argument fails. Further, I will discuss Boyd’s semantic theory as well (...) as attempts to improve upon it, raise serious problems for these semantic accounts, and suggest an alternative view that accounts for our use of moral terms.

It is widely believed that Twin-Earth-style thought experiments show that the contents of a person's thoughts fail to supervene on her intrinsic properties. Several recent philosophers have made the further claim that Twin-Earth-style thought experiments produce metaphysically necessary conditions for the possession of certain concepts. I argue that the latter view is false, and produce counterexamples to several proposed conditions. My thesis is of particular interest because it undermines some attempts to show that externalism is incompatible with privileged (...) access. (shrink)

In this paper I revisit an important response to the Moral Twin Earth (MTE) challenge: The Common Functional Role strategy (CFR). I argue that CFR is open to a revenge problem. MTE-cases allegedly show that two linguistic communities can be in genuine disagreement even when they are regulated by distinct families of properties. CFR provides a way to reconcile the intuition that the two communities are in genuine disagreement with the claim that the use of moral terms by both (...) communities is causally regulated by different families of properties. This is done by identifying a functional role that those families of properties both fulfill. Still, even if CFR is successful, its proponents need to face a serious revenge problem. Roughly, it could be that the families of properties that regulate each community are equally perfect realizers of the relevant higher-order functional state. I suggest that the proponent of CFR faces a dilemma: either CFR has controversial implications about first-order moral theory, or CFR needs to be coupled with substantive and parochial empirical/metaphysical assumptions to avoid those implications.

This paper presents two cases demonstrating that theories allowing the environment to partially determine the content of moral concepts provide incorrect truth-conditions for moral terms. While typical Moral Twin Earth cases seek to establish that these theories fail to account formoral disagreement, neither case here essentially involves interpersonal disagreement. Both involve a single person retaining moral beliefs despite recognizing actual or potential mismatches with the purportedly content-determining facts. This lets opponents of such theories grant objections that standard Moral (...) class='Hi'>Twin Earth cases fail to demonstrate disagreement, and argue more straightforwardly that they generate implausible truth-conditions for moral claims.

Michael Scriven’s (1959) example of identical twins (who are said to be equal in fitness but unequal in their reproductive success) has been used by many philosophers of biology to discuss how fitness should be defined, how selection should be distinguished from drift, and how the environment in which a selection process occurs should be conceptualized. Here it is argued that evolutionary theory has no commitment, one way or the other, as to whether the twins are equally fit. This is (...) because the theory of natural selection is fundamentally about the fitnesses of traits, not the fitnesses of token individuals. A plausible philosophical thesis about supervenience entails that the twins are equally fit if they live in identical environments, but evolutionary biology is not committed to the thesis that the twins live in identical environments. Evolutionary theory is right to focus on traits, rather than on token individuals, because the fitnesses of token organisms (as opposed to their actual survivorship and degree of reproductive success) are almost always unknowable. This point has ramifications for the question of how Darwin’s theory of evolution and R. A. Fisher’s are conceptually different. (shrink)

Physicists Brian Greene and Max Tegmark both make variants of the claim that if the universe is infinite and matter is roughly uniformly distributed, then there are infinitely many “people with the same appearance, name and memories as you, who play out every possible permutation of your life choices.” In this paper I argue that--while our current best theories in astrophysics may allow one to conclude that we have infinitely many duplicates whose lives are identical to our own from start (...) to finish--without either further advances in physics or advances in fields like biology, psychology, neuroscience, and philosophy, Greene’s and Tegmark’s claims about the ways in which our duplicates lives will differ from our own are not a consequence of our best current scientific theories. Rather, I argue that Greene and Tegmark’s conclusions rely on philosophically imprecise usages of the language of “possibility.”. (shrink)

The Burge-Putnam thought experiments have generated the thesis that beliefs are not fixed by the constitution of the body. However, many philosophers have thought that if this is true then there must be another content-like property. Even if the contents of our attitudes such as the one in ‘believes that aluminum is a light metal’, do not supervene on our physical makeups, nevertheless people who are physical duplicates must be the same when it comes to evaluating their rationality and explaining (...) their actions. I argue that the considerations motivating this view are best handled with just the ordinary ‘that’-clause contents. (shrink)

In this article, I examine a new concept of “Twin Memory’ which has emerged in memory classification research of conscious and unconscious memory representations. It is to analyse the presence of twin memory among the various memory systems, and also to provide a platform for the twin memory “anatomy” in the field of cognitive science, neuropsychology and neuroscience.

Time contraction is not a property of the moving body. Permanent contraction is against the constancy of the speed of light. Einstein uses wrong units of measurement and comes to wrong conclusions. We use the translation of the article "On the electrodynamics of moving bodies".

It places particular emphasis on urban scale digital twins, which are virtual replicas of cities that are used to simulate environments and develop scenarios in response to policy problems. The article also investigates the shift from the technical to the socio-technical perspective within the field of smart cities. Despite the aspirations of urban scale digital twins to enhance the (...) participation of citizens in the decision-making processes relayed to urban planning strategies, the fact that they are based on a limited set of variables and processes makes them problematic. The article aims to shed light on the tension between the real and the ideal at stake during this process of abstracting sets of variables and processes in the case of urban scale digital twins.

This paper presents a new challenge for libertarianism. The problem, in a nutshell, is that libertarianism appears to self-destruct in cases where conjoined twins—who share body parts—disagree over what to do with them. The problem is explored, and some solutions are proposed. The verdict is that accepting any of them will make libertarianism harder to defend.

In his recent book Physicalism, Daniel Stoljar argues that there is no version of physicalism that is both true and deserving of the name. His argument employs a variation of Hilary Putnam’s famous twin-earth story, which Stoljar calls “the twin-physics world.” In this paper, I challenge Stoljar’s use of the twin-physics world. The upshot of that challenge, I argue, is that Stoljar fails to show, concerning the versions of physicalism for which he grants the possibility of being (...) true, that none of them is deserving of the name.

The purpose of this article is to compare several street typologies (distributed from center to suburb) in Tirana, Albania while taking into consideration pedestrian behavior on these pathways. The streets "Myslym Shyri," "Bllok," "Kombinat" (an extension of Kavaja's Street), and "Ana Komnena" (formerly "Fusha e Aviacionit") will be the primary focus of this study. The following variables will be taken into account such as pedestrian behaviors, street identity, dissatisfaction, walking distance when shifting to another zone, effects of greenery on (...) pedestrians, time spent, points of interest, frequency, pavement quality, preferred walking periods, gathering places, utilization of benches, ambulant sellers, impact of vegetation and greenery, water basins, preference for public transportation, and road signs. Direct observations and a questionnaire will be used to determine the accurate information. The study should provide recommendations as guidance for municipalities and stakeholders to better understand the behavior of pedestrians in Tirana’s context. The streets that pedestrians frequent the most include the "Bllok" area and "Myslym Shyri" Street. The pedestrian resident population on "Myslym Shyri" street, which is dominated by people of all ages, including children, youth, and the elderly, has a slight advantage over the "Bllok" neighborhood. Furthermore, there is a wide variety of urban elements on Ana Komnena Street (formerly known as "Fusha e Aviacionit"). Meanwhile, the pedestrians on Kombinati’s street suffer a little bit more because of the traffic congestion and vehicle pollution. (shrink)

Various cases of conjoined twinning have been presented as problems for the animalist view that we are animals. In some actual and possible cases of human dicephalus that have been discussed in the literature, it is arguable that there are two persons but only one human animal. It is also tempting to believe that there are two persons and one animal in possible instances of craniopagus parasiticus that have been described. Here it is argued that the animalist can admit that (...) these are cases in which human persons are not animals, without forfeiting the title “animalist.” It is also shown that this is not only an option but also a well-motivated and plausible option for the animalist. Seeing this requires getting clear on what the word “we” should be thought to include in the animalist's claim that we are animals. Here animalism is defended against twinning objections by figuring out how to view the scope of the animalist's identity claim. (shrink)

This paper offers a simple response to the Moral Twin Earth (MTE) objection to Naturalist Moral Realism (NMR). NMR typically relies on an externalist metasemantics such as a causal theory of reference. The MTE objection is that such a theory predicts that terms like ‘good’ and ‘right’ have a different reference in certain twin communities where it’s intuitively clear that the twins are talking about the same thing when using ‘good’. I argue that Boyd’s causal regulation theory, the (...) original target of the MTE objection, was never vulnerable to this objection. The theory contains an epistemic constraint on reference which implies that either the property that causally regulates uses of ‘good’ isn’t different for the twin communities or, in scenarios where the reference is different, the communities diverge in ways where it’s not intuitively clear that ‘good’ has the same reference for them.

Review of Gibbs' book in which he argues against the twin assumptions that language is inherently literal, and that thought itself is literal. Metaphors, etc., are omnipresent in language, Gibbs argues, and the mind is inherently 'poetic', i.e., it engages in figurative thinking. For example, we conceptualize anger as "ANGER IS HEATED FLUID IN A CONTAINER" (p. 7), and as a result, that is how we talk about anger ('Bill is getting hot under the collar,' 'She blew up at (...) me', etc.).

Digital Twins are conceptualised in the academic technical discourse as real-time realistic digital representations of physical entities. Originating from product engineering, the Digital Twin quickly advanced into other fields, including the life sciences and earth sciences. Digital Twins are seen by the tech sector as the new promising tool for efficiency and optimisation, while governmental agencies see it as a fruitful means for improving decision-making to meet sustainability goals. A striking example of the latter is the European Commission who (...) wishes to delegate a significant role to Digital Twins in addressing climate change and supporting Green Deal policy. As Digital Twins give rise to high expectations, ambitions, and are being entrusted important societal roles, it is crucial to critically reflect on the nature of Digital Twins. In this article, we therefore philosophically reflect on Digital Twins by critically analysing dominant conceptualisations, the assumptions underlying them, and their normative implications. We dissect the concept and argue that a Digital Twin does not merely fulfil the role of being a representation, but is in fact a steering technique used to direct a physical entity towards certain goals by means of multiple representations. Currently, this steering seems mainly fuelled by a reductionist approach focused on efficiency and optimisation. However, this is not the only direction from which a Digital Twin can be thought and, consequently, designed and deployed. We therefore set an agenda based on a critical understanding of Digital Twins that helps to draw out their beneficial potential, while addressing their potential issues. (shrink)
