In the research field of machine ethics, we commonly categorize artificial moral agents into four types, with the most advanced referred to as a full ethical agent, or sometimes a full-blown Artificial Moral Agent (AMA). This type has three main characteristics: autonomy, moral understanding and a certain level of consciousness, including intentional mental states, moral emotions such as compassion, the ability to praise and condemn, and a conscience. This paper aims to discuss various aspects of full-blown AMAs and presents the (...) following argument: the creation of full-blown artificial moral agents, endowed with intentional mental states and moral emotions, and trained to align with human values, does not, by itself, guarantee that these systems will have _human_ morality. Therefore, it is questionable whether they will be inclined to honor and follow what they perceive as incorrect moral values. we do not intend to claim that there is such a thing as a universally shared human morality, only that as there are different human communities holding different sets of moral values, the moral systems or values of the discussed artificial agents would be different from those held by human communities, for reasons we discuss in the paper.

This paper critically examines Coeckelbergh’s (2023) performative view of moral status. Drawing parallels to Searle’s social ontology, two key claims of the performative view are identified: (1) Making a moral status claim is equivalent to making a moral status declaration. (2) A successful declaration establishes the institutional fact that the entity has moral status. Closer examination, however, reveals flaws in both claims. The second claim faces a dilemma: individual instances of moral status declaration are likely to fail because they do (...) not conform to established moral discourse conventions, and reliance on declarations becomes both unnecessary and implausible for explaining widespread collective recognition of moral status. As for the first claim, accepting it undermines the potential for meaningful moral disagreement. As a remedy, this paper proposed a shift in perspective: interpreting moral status claims as assertions rather than declarations. This refined perspective provides a more plausible framework for understanding moral status and avoids the pitfalls associated with the performative view. (shrink)

South Africa has been undergoing a process of transformation since the end of White minority rule in 1994. During this period, various employment and lifestyle opportunities have given rise to a growing Black middle class. Against this backdrop, the article draws upon an intersectional approach to corpus-assisted discourse studies in order to examine the construction of the BMC in a 1.4 million-word corpus composed of 20 mainstream Anglophone South African newspaper titles published between 2008 and 2014. With the help of (...) the corpus tool AntConc, the article investigates the collocates of ‘black middle class’, ‘black diamonds’, ‘clever blacks’ and ‘coconuts’, classifying results according to semantic categories in order to provide an idea of the multiple but nuanced representations of the BMC in contemporary SA. The analysis finds several lexically rich moralizing and paternalistic discourses that, in accordance with an intersectional perspective, enact a complex pattern of strategies that are simultaneously exclusionary and inclusionary.

Improving human characteristics goes beyond compensating for an impairment. This book explores the rich and complex relationship between enhancement and impairment, showing that the study of disability offers new ways of thinking about the social and ethical implications of improving the human condition.

As a way of comparing qualitative and quantitative approaches to critical discourse analysis, two analysts independently examined similar datasets of newspaper articles in order to address the research question ‘How are different types of men represented in the British press?’. One analyst used a 41.5 million word corpus of articles, while the other focused on a down-sampled set of 51 articles from the same corpus. The two ensuing research reports were then critically compared in order to elicit shared and unique (...) findings and to highlight strengths and weaknesses between the two approaches. This article concludes that an effective form of CDA would be one where different forms of researcher expertise are carried out as separate components of a larger project, then combined as a way of triangulation.

This article contributes to an emerging literature on the “neo” or “entrepreneurial” developmental state that emphasizes the role of innovation policy in promoting the structural transformation of industry. It finds further evidence that supports this approach and advances it by making two unique contributions. First, it highlights an essential yet underappreciated feature of contemporary innovation policy: the state’s capacity to condition public assistance and discipline private firms that do not adhere to government guidelines. These capacities are necessary to guarantee that (...) the benefits of public investment in innovation—the social and economic spillovers—are not appropriated by private actors but shared more broadly within society. Second, it highlights that politics—reflected in the relations between innovation agencies and key social actors—represents an important causal factor in both the formation and subsequent transformation of these institutional capacities. These points are illustrated through a historical analysis of a crucial case: the state-led development of Israel’s thriving high-tech sector. (shrink)

What happens when men and women feel powerful in intimate relationships? When does power corrupt and when does it lead to positive consequences, such as increased sensitivity to others' needs, personal growth, and social responsibility? This book offers anyone interested in such questions a clear and accessible depiction of the effects of social power, based on cutting-edge theory and research. The book starts with a general discussion on the ways power influences individuals. The role of one's personality, goals, and culture (...) seem to play a decisive role in whether power leads to benevolent or malevolent consequences. Some effects of power are more intuitively understood (e.g., taking from or contributing to a common resource, or aggressive responses in parents who feel powerless), while other effects regard much more surprising phenomena (e.g., self-fulfilling prophecies, stopping an annoying fan, or forgiveness for a transgression). Following the description of this social-psychological mechanism, The Power to Care discusses the cultural and developmental circumstances in which power is experienced. Culturally acquired gender-roles, experiencing racism, egoistic vs. altruistic motivations, and defensive tendencies - all influence what men and women want in intimate relationships, and the way power can motivate them to attain their goals. These circumstances may explain the gender differences found in the results of three experiments, described in Chapter 4. In these experiments, men and women in long-term, intimate relationships reacted differently to a temporary sense of power, in terms of their tendency to self-focus, take the perspective of others, and objectify their relationship partners.In the last section, The Power to Care discusses the seemingly contradictory beliefs of professionals and laymen alike, that power corrupts, but that the empowerment processes yields positive results. In this section, the role of power and empowerment processes is discussed, mainly in macro-level interventions, in intimate partner violence (for both victims and perpetrators), overcoming addiction, and in policy practice (e.g., in court verdicts regarding cases of post-divorce relocation of custodial parents).

This article reconstructs the political motivation argument against cosmopolitanism, according to which the extension of social justice beyond bounded communities would be motivationally unstable, and thus unjustified. It does so through an analysis of the stability problem, and a reconstruction of the three most prominent anti-cosmopolitan arguments—Rawlsian statism, liberal nationalism, and civic republicanism—as solutions to this problem. It then examines, and rejects, three prominent objections, each denying a different level of the argument. The article concludes that the civic republican version (...) of the argument is the most plausible, and implications for cosmopolitanism are considered. (shrink)

According to the so-called Hempel’s Dilemma, the thesis of physicalism is either false or empty. Our intention in this paper is not to propose a solution to the Dilemma, but rather to argue as follows: to the extent that Hempel’s Dilemma applies to physicalism it equally applies to any theory that gives a deep-structure and changeable account of our experience or of high-level theories. In particular, we will show that it also applies to mind-body dualistic theories. The scope of Hempel’s (...) Dilemma turns out to be very wide: it is a special case of a general sceptical argument against changeable deep-structure theories in and outside science. (shrink)

In recent years, state-of-the-art artificial intelligence systems have started to show signs of what might be seen as human level intelligence. More specifically, large language models such as OpenAI’s GPT-3, and more recently Google’s PaLM and DeepMind’s GATO, are performing amazing feats involving the generation of texts. However, it is acknowledged by many researchers that contemporary language models, and more generally, learning systems, still lack important capabilities, such as understanding, reasoning and the ability to employ knowledge of the world and (...) common sense in order to reach or at least advance toward general intelligence. Some believe that scaling will eventually bring about these capabilities; others think that a different architecture is needed. In this paper, we focus on the latter, with the purpose of integrating a theoretical–philosophical conception of understanding as knowledge of dependence relations, with the high-level requirements and engineering design of a robust AI system, which integrates machine learning and symbolic components.

While many argue investment-based criteria for immigration are wrong or at least problematic, skill-based criteria remain relatively uncontroversial. This is normatively inconsistent. This article assesses three prominent normative objections to investment-based selection criteria for immigrants: that they wrongfully discriminate between prospective immigrants that they are unfair, and that they undermine political equality among citizens. It argues that either skill-based criteria are equally susceptible to these objections, or that investment-based criteria are equally shielded from them. Indeed, in some ways investment-based criteria (...) are less normatively problematic than skill-based criteria. Given this analysis, the resistance to investment-based migration criteria, but not to skill-based criteria, is inconsistent. (shrink)

The expressivist account of knowledge attributions, while claiming that these attributions are nonfactual, also typically holds that they retain a factual component. This factual component involves the attribution of a belief. The aim of this work is to show that considerations analogous to those motivating an expressivist account of knowledge attributions can be applied to belief attributions. As a consequence, we claim that expressivists should not treat the so-called factual component as such. The phenomenon we focus on to claim that (...) belief attributions are non-factual is that of normative doxastic disagreement. We show through several examples that this kind of disagreement is analogous to that of the epistemic kind. The result will be a doxastic expressivism. Finally, we answer some objections that our doxastic expressivism could seem to face. (shrink)

Proclus, successor of the School of Athens in the fifth century AD, is one of the last great voices of a pagan polytheistic world in crisis in the face of the gradual rise of Christianity. His writing bears witness not only to one of the most influential metaphysical representations for the constitution of the idea of a philosophical "system" based on a complex "language game" based on the conceptual sphere of "order" and "unity", but also of an attempt to reconcile (...) rhetorics with philosophy. In the three chapters in which the book is structured (style, system, unity), then, a conscious intention is evident in Proclus, to adapt the content of his systematic metaphysics to literary form. Hence there is a consistency traced in Proclus' stylistic choices, with the aesthetic norms of a rhetorical canon, probably established in the cycle of readings of the Neoplatonic school.

In this paper, I begin by defending permissivism: the claim that, sometimes, there is more than one way to rationally respond to a given body of evidence. Then I argue that, if we accept permissivism, certain worries that arise as a result of learning that our beliefs were caused by the communities we grew up in, the schools we went to, or other irrelevant influences dissipate. The basic strategy is as follows: First, I try to pinpoint what makes irrelevant influences (...) worrying and I come up with two candidate principles. I then argue that one principle should be rejected because it is inconsistent with permissivism. The principle we should accept implies that it is sometimes rational to maintain our beliefs, even upon learning that they were caused by irrelevant influences. (shrink)

The question of whether it is ever permissible to believe on insufficient evidence has once again become a live question. Greater attention is now being paid to practical dimensions of belief, namely issues related to epistemic virtue, doxastic responsibility, and voluntarism. In this book, McCormick argues that the standards used to evaluate beliefs are not isolated from other evaluative domains. The ultimate criteria for assessing beliefs are the same as those for assessing action because beliefs and actions are both products (...) of agency. Two important implications of this thesis, both of which deviate from the dominant view in contemporary philosophy, are 1) it can be permissible to believe for non-evidential reasons, and 2) we have a robust control over many of our beliefs, a control sufficient to ground attributions of responsibility for belief.

Artificial general intelligence is not a new notion, but it has certainly been gaining traction in recent years, and academic as well as industry resources are redirected to research in AGI. The main reason for this is that current AI techniques are limited as they are designed to operate in specific problem-domains, following meticulous preparation. These systems cannot operate in an unknown environment or under conditions of uncertainty, reuse knowledge gained in another problem domain, or autonomously learn and understand the (...) problem-domain. We shall call AI systems capable of such feats artificial general intelligent systems. The three tasks of this paper are to provide a working definition of the term AGI, examine the “missing G”, i.e., the set of abilities that current AI systems lack and whose implementation will result in a basic AGI system, and consider different approaches, including a hybrid one, to a comprehensive solution for an AGI.

Ostracism is known to cause psychological distress. Thus, defining the factors that can lead to recovery or diminish these negative effects is crucial. Three experiments examined whether suggesting the possible causes of ostracism to victims could decrease or eliminate their ostracism distress. They also examined whether death-anxiety mediated the association between the suggested possible cause for being ostracized and recovery. Participants were randomly assigned to six experimental and control groups and were either ostracized or included in a game of Cyberball. (...) Two control conditions were used: participants who were ostracized but received no explanation and participants who were included. Immediately after the ostracism experience, participants in the experimental groups were presented with one of four causes for being ostracized, using locus of control and stability, the two causal dimensions of Weiner’s attribution theory. After a short delay they were administered a mood or needs-satisfaction questionnaire. The results highlight the interaction between locus of control and stability, and underscore the relative importance of different attributions in alleviating self-reported ostracism distress. Specifically, both external and unstable attributions decreased distress, and an unstable attribution led to complete recovery in some participants. Thus, recovery from ostracism may be accelerated when the victim receives an explanation for ostracism that attributes the incident to unstable, external causes soon after the incident. Death-anxiety fully mediated the association between locus of control attribution and mood, but for on needs-satisfaction or the stability of the attribution. (shrink)

As even those who endorse it concede, cosmopolitanism has a motivational problem. There is a need for strategies to generate support of global norms conducive to cosmopolitanism, but which do not rely primarily on the motivating force of the moral argument. This article makes the case for civic vigilance as an answer to this problem. It argues that support for cosmopolitan norms could be advanced by encouraging a recognition of the ‘boomerang effect’: the ways in which global injustice undermines the (...) freedom of one’s own political community. The article offers evaluative criteria for different motivational strategies, assesses prominent alternatives to moral motivation, and finally defends the appeal to civic vigilance. (shrink)

When discussing AI alignment, we usually refer to the problem of teaching or training advanced autonomous AI systems to make decisions that are aligned with human values or preferences. Proponents of this approach believe it can be employed as means to stay in control over sophisticated intelligent systems, thus avoiding certain existential risks. We identify three general obstacles on the path to implementation of value alignment: a technological/technical obstacle, a normative obstacle, and a calibration problem. Presupposing, for the purposes of (...) this discussion, that the technical and normative problems are solved, we focus on the problem of how to calibrate a system, for a specific value, to be on a specific location within a spectrum stretching between righteous and normal or average human behavior. Calibration, or more specifically mis-calibration, also raises the issue of trustworthiness. If we cannot trust AI systems to perform tasks the way we intended, we would not use them on our roads and at our homes. In an era where we strive to construct autonomous machines endowed with common sense, reasoning abilities and a connection to the world, so they would be able to act in alignment with human values, such mis-calibrations can make the difference between trustworthy and untrustworthy systems.

Daniel Weiskopf has recently raised an apparently powerful objection against the so-called “extended mind thesis” with regard to beliefs. His argument is that since alleged cases of “extended beliefs” lack a characteristic feature of beliefs properly so called (newly acquired beliefs are usually integrated with already existing beliefs rapidly, automatically and unconsciously), they do not count as genuine beliefs properly so called. We defend the extended mind thesis by arguing that Weiskopf is wrong. First, we suggest an alternative account of (...) informational integration that is compatible with externally stored beliefs’ being beliefs properly so called, emphasizes the crucial role action plays for cognition, and stresses the embodied and situationally embedded nature of human cognizers. Second, we argue that even if informational integration were usually rapid, automatic, and unconscious, this would not be an essential feature of beliefs. Third, we argue that even if rapid, automatic, and unconscious informational integration were characteristic of our commonsense conception of beliefs, externally stored “beliefs” would still be sufficiently similar to beliefs properly so called for them to be grouped together for all practical and scientific purposes.

This paper is about the connection between rationality and accuracy. I show that one natural picture about how rationality and accuracy are connected emerges if we assume that rational agents are rationally omniscient. I then develop an alternative picture that allows us to relax this assumption, in order to accommodate certain views about higher order evidence.

Greaves and Wallace argue that conditionalization maximizes expected accuracy. In this paper I show that their result only applies to a restricted range of cases. I then show that the update procedure that maximizes expected accuracy in general is one in which, upon learning P, we conditionalize, not on P, but on the proposition that we learned P. After proving this result, I provide further generalizations and show that much of the accuracy-first epistemology program is committed to KK-like iteration principles (...) and to the existence of a class of propositions that rational agents will be certain of if and only if they are true.

This paper investigates the production and circulation of the illustrations in Fritz Kahn’s five-volume series The Life of Man, one of the most popular medical publications in the German interwar period. In 1912 Kahn (1888–1968), together with a staff of illustrators, began producing what would later become his best-selling series. Illustrations of this series (in particular, the poster The human factory/der Mensch als Industriepalast) were widespread throughout Germany during the Weimar Republic. With the rise of National Socialism, Kahn was forced (...) to emigrate in 1933. While his books were forbidden by the Nazi regime, their illustrations continued to play an important role in popular scientific discourse: they reappeared in the Nazi health-education programme and were adapted for Kahn’s publications in exile at the same time. This paper discusses how their production process and collective authorship made this complex and heterogeneous reception possible. (shrink)

In recent years, permissivism—the claim that a body of evidence can rationalize more than one response—has enjoyed somewhat of a revival. But it is once again being threatened, this time by a host of new and interesting arguments that, at their core, are challenging the permissivist to explain why rationality matters. A version of the challenge that I am especially interested in is this: if permissivism is true, why should we expect the rational credences to be more accurate than the (...) irrational ones? My aim is to turn this challenge on its head and argue that, actually, those who deny permissivism will have a harder time responding to such a challenge than those who accept it. (shrink)

Triggered Inversion (TI) in Hebrew has been previously analyzed as canonical A'-movement to the specificer position of a functional projection in the CP-layer (Doron & Shlonsky 1990, Shlonsky 1997). This article examines the semantic properties of TI constructions in Hebrew, specifically the cross-linguistic similarities between TI in Hebrew and pseudoclefts (PC) in English, as discussed in Heycock & Kroch (1999). A structure is proposed for Hebrew TI that parallels the structure given for equatives in Hebrew by Rothstein (1995), in which (...) the trigger is base-generated in the operator layer and the inverted surface word order is an artifact of subject movement to a position below that of the verb. Finally, TI is considered in the crosslinguistic typology of focus constructions outlined in Kiss (1998). (shrink)

The article deals with larger stretches of talk-in-interaction and argues in favor of a descriptive approach, which integrates the structural requirements of global organization, the special type of sequential orderliness within larger units as well as the genre-orientation of these units. Drawing on previous work in conversation analysis, discourse analysis and the sociological genre analysis, the article introduces GLOBE as an analytical tool which functionally links discourse units to conventionalized communicative purposes. GLOBE reconstructs the interactive achievement of genre-oriented discourse units (...) in a three-branch analysis of jobs, devices and forms. The analytical potential of GLOBE is demonstrated in the exemplary genre-contrastive analysis of a narrative, an explanative and an argumentative excerpt. On the basis of the analyses of the three genres, the overarching constitution of genre-oriented global units is then explicated. (shrink)

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The argument for this will require a generalization of (...) an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self-locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality. (shrink)

The convergence of morphogenesis into viable organisms under variable conditions suggests closed‐loop dynamics involving multiscale functional feedback. We develop the idea that morphogenesis is based on synergy between mechanical and bio‐signaling processes, spanning all levels of organization: molecular, cellular, tissue, up to the whole organism. This synergy provides feedback within and between all levels of organization, to close the loop between the dynamics of the morphogenesis process and its robust functional outcome. Hydra offer a powerful platform to explore this direction, (...) thanks to their simple body plan, extraordinary regeneration capabilities, and the accessibility and flexibility of their tissues. Our recent experiments show that structural inheritance of the actomyosin organization directs body‐axis formation during Hydra regeneration. Morphogenesis is then stabilized through dynamic cytoskeletal reorganization induced by the inherited structure. The observed cytoskeletal stability and reorganization capabilities suggest that mechanical feedback integrates with biochemical processes to establish viable patterns and ensure canalization.

One of the distinctive features of the primate genome is the Alu element, a repetitive short interspersed element, over a million highly similar copies of which account for >10% of the genome. A direct consequence of this feature is that primates' transcriptome is highly enriched in long stable dsRNA structures, the preferred target of adenosine deaminases acting on RNAs (ADARs), which are the enzymes catalyzing A‐to‐I RNA editing. Indeed, A‐to‐I editing by ADARs is extremely abundant in primates: over a hundred (...) million editing sites exist in their genomes. However, there are few essential editing sites conserved across mammals that have maintained their editing level despite the radical change in ADAR target landscape. Here, we review and discuss the cost of having an unusual amount of dsRNA and editing in the transcriptome, as well as the opportunities it presents, which might have contributed to the accelerated evolution of the primates.

A major trend that characterized the naturalization of the Aristotelian habitus concept in the medieval Islamic world was its application to religious discourses. This trend was not limited to the works of Muslim thinkers. The present communication focuses on the ways in which Maimonides used the concept, naturalizing it in the religious Jewish system.

Habitus is a logical and ethical Aristotelian concept that was first introduced to the Islamic world through the translation of Greek philosophical works into Arabic in the ninth century. Following its introduction and until the nineteenth century, thinkers and scholars of the Islamic world naturalized it creatively in various intellectual systems. In ethical usage, habitus is a disposition that, once acquired and well established through a process of accustoming, allows humans to perceive and act in certain ways without deliberation or (...) reflection. This concept explained how humans transcended their inborn natures, and as such it was amenable to employment in manifold fields and contexts. The present article studies significant applications from the ninth to the nineteenth century by thinkers of the Islamic world, who fleshed out the Aristotelian concept and used it for their own purposes. Among other things, it shows that the two main trends of naturalization involved application of the concept to religious Islamic discourses and to the study of humans and their society, anticipating modern Western sociological usage.

This article examines how Arabic handled societal taboos in the medieval Islamic world and the ways by which language users applied censorship that led to the creation of euphemisms. Special attention is given to sources from the eastern part of the Islamic world dating to the fourth/tenth and the fifth/eleventh centuries, and to the taboo topics and types of euphemisms they disclose. The complex relationship between the concept of euphemism and kināya, the polysemous Arabic term that renders it, is examined. (...) As a whole, the evidence demonstrates an overwhelming Arabic preference for figurative speech over change of form as the essential generation mechanism of euphemisms. Finally, light is shed on the ways in which discerning medieval literary critics anticipated significant modern sociolinguistic observations: the relations between euphemism, orthophemism, and dysphemism, in addition to the incessant process of euphemism degradation.

I argue that in many cases, there are good reasons to engage with people who hold fringe beliefs such as debunked conspiracy theories. I (1) discuss reasons for engaging with fringe beliefs; (2) discuss the conditions that need to be met for engagement to be worthwhile; (3) consider the question of how to engage with such beliefs, and defend what Jeremy Fantl has called “closed-minded engagement” and (4) address worries that such closed-minded engagement involves problematic deception or manipulation. Thinking about (...) how we engage with irrational emotions offers a way of responding to these concerns. Reflection on engagement with fringe beliefs has wider implications for two distinct philosophical discussions. First, it can help illuminate the nature of beliefs, lending support to the view that not all states which are deeply resistant to evidence thereby fail to be beliefs. Second, an implication of the view I put forth is that it need not constitute a lack of respect to adopt what Peter Strawson called “the objective stance” in relationships. (shrink)

A model of Peano Arithmetic is short recursively saturated if it realizes all its bounded finitely realized recursive types. Short recursively saturated models of $\PA$ are exactly the elementary initial segments of recursively saturated models of $\PA$. In this paper, we survey and prove results on short recursively saturated models of $\PA$ and their automorphisms. In particular, we investigate a certain subgroup of the automorphism group of such models. This subgroup, denoted $G|_{M(a)}$, contains all the automorphisms of a countable short (...) recursively saturated model of which can be extended to an automorphism of the countable recursively saturated elementary end extension of the model.
