In the ongoing research of the functions of consciousness, special emphasis has been put on integration of information: the ability to combine different signals into a coherent, unified one. Several theories of consciousness hold that this ability depends on – or at least goes hand in hand with – conscious processing. Yet some empirical findings have suggested otherwise, claiming that integration of information could take place even without awareness. Trying to reconcile this apparent contradiction, the “windows of integration” hypothesis claims (...) that conscious access enables signal processing over large integration windows. The hypothesis applies to integration windows defined either temporally, spatially, or semantically. In this review, we explain the hypothesis and re-examine it in light of new studies published since it was suggested. In line with the hypothesis, these studies provide compelling evidence for unconscious integration, but also demonstrate its limits with respect to time, space, and semantic distance. The review further highlights open questions that still need to be pursued to demonstrate the applicability of the WOI hypothesis as a guiding principle for understanding the depth and scope of unconscious processes.

The neurocentric worldview that identifies the essence of the human being with the material brain has become a central paradigm in current academic discourse. Israeli researchers also seek to understand educational principles and processes via neuroscientific models. On this background, the article uncovers the central role that visual brain images play in the learning-disabilities field in Israel. It examines the place brain images have in the professional imagination of didactic-diagnosticians as well as their influence on the diagnosticians' clinical attitudes. It (...) relies on two theoretical fields: sociology and anthropology of the body and sociology of neuromedical knowledge. The research consists of three methodologies: ethnographic observations, in-depth interviews, and rhetorical analysis of visual and verbal texts. It uncovers the various rhetorical and ideological functions of brain images in the field. It also charts the repertoire of rhetorical devices which are utilized to strengthen the neuroreducionist messages contained in the images. (shrink)

Many believe that severe intellectual impairment, blindness or dying young amount to serious harm and disadvantage. It is also increasingly denied that it matters, from a moral point of view, whether something is biologically normal to humans. We show that these two claims are in serious tension. It is hard explain how, if we do not ascribe some deep moral significance to human nature or biological normality, we could distinguish severe intellectual impairment or blindness from the vast list of seemingly (...) innocent ways in which we fail to have as much wellbeing as we could, such not having super‐intelligence, or not living to 130. We consider a range of attempts to draw this intuitive normative distinction without appealing to normality. These, we argue, all fail. But this doesn't mean that we cannot draw this distinction or that we must, implausibly, conclude that biological normality does possess an inherent moral importance. We argue that, despite appearances, it is not biological normality but rather statistical normality that, although lacking any intrinsic moral significance, nevertheless makes an important moral difference in ways that explain and largely justify the intuitive distinction.

A comprehensive introduction to formal logic, Logic and Philosophy: A Modern Introduction is a rigorous yet accessible text, appropriate for students encountering the subject for the first time. Abundant, carefully crafted exercise sets accompanied by a clear, engaging exposition build to an exploration of sentential logic, first-order predicate logic, the theory of descriptions, identity, relations, set theory, modal logic, and Aristotelian logic. And as its title suggests, Logic and Philosophy is devoted not only to logic but also to the philosophical (...) debates that led to the development of the field. Much new material has been added for the 13th edition. An introduction to set theory and its relationship to logic and mathematics, including philosophical issues, is now part of Chapter 13. Chapter 15 is an introduction to modal logic and Kripke semantics, concluding with a discussion of philosophical problems with any logical accommodation of modalities. Instructors who do not wish to present proof methods will find chapters on truth trees for both sentential and first-order logic, and a presentation of trees for modal logic. Special features of this text include presentations of the history of logic, alternatives to traditional methods of conditional and indirect proof, and a discussion of semantic problems with universal and existential instantiations. Throughout, the authors are sensitive to philosophical issues that arise from the relationship between ordinary language, symbolic logic, and justifications for the syntax and semantics of the various symbolic languages. Discussions range from the justification of the truth table for the sentential rendering of if... then statements to semantic and syntactic paradoxes, including some troubling paradoxes that arise in ordinary language (e.g., the so-called hangman or surprise quiz paradox). Logic and Philosophy includes ample material for a one-semester or two-semester course and provides a thorough preparation for more advanced logic courses. (shrink)

Resisting Contextual Information: You Can't Put a Salient Meaning Down Two experiments support the graded salience hypothesis, which assumes that early processing involves distinct mechanisms-linguistic and contextual-that do not interact but run parallel. While contextual processes make up an integrative, top-down mechanism that benefits from linguistic and extra-linguistic information, the linguistic mechanism is modular. Using Vu et al.'s materials, Experiment 1 shows that the sentential position of a target word is crucial for the operation of the global, predictive mechanism, whose (...) effects, accumulated in prior discourse, mask lexical effects in final, but not in initial position. Experiment 2 shows that even in a sentential position that favors contextual effects, lexical access is not affected: Salient meanings are activated upon encounter of the lexical stimulus, regardless of contextual information to the contrary. Taken together, these findings argue against direct access models, which suggest that context can selectively activate the appropriate meaning, regardless of salience. (shrink)

This paper examines how Japanese leading politicians cope with the communication problems posed during televised political interviews. Based on data gathered during the year 2012 equivocation, thereby to also assess the significance of these talk shows in the broader context of political communication in Japan.

This book tries to answer two key questions. The first is why certain periods are more prone to war than others. The other is why certain wars that involve polar powers end with their territorial expansion whereas other wars end in their contraction or maintaining their territorial status. In conclusion, it is asked whether the polarity of the system affects these two outcomes, and if so, how.

The notion of bilattice was introduced by Ginsberg, and further examined by Fitting, as a general framework for many applications. In the present paper we develop proof systems, which correspond to bilattices in an essential way. For this goal we introduce the notion of logical bilattices. We also show how they can be used for efficient inferences from possibly inconsistent data. For this we incorporate certain ideas of Kifer and Lozinskii, which happen to suit well the context of our work. (...) The outcome are paraconsistent logics with a lot of desirable properties.1.

Sometimes, the availability of more evidence for a conclusion provides a reason to believe in its falsity. This counter-intuitive phenomenon is related to the idea of higher-order evidence, which has attracted broad interest in recent epistemological literature. Occasionally, providing more evidence for something weakens the case in its favor, by casting doubt on the probative value of other evidence of the same sort or on the fact-finder’s cognitive performance. We analyze this phenomenon, discuss its rationality, and outline possible application to (...) evidence law and to the law in general. It is suggested, inter alia, that such higher-order evidence may explain how judicial experience-based expertise in fact-finding is possible despite the absence of a feedback mechanism; and that fact-finders’ self-doubt regarding their own competence in making ‘beyond-reasonable doubt’ judgments might be reasonable and should not be ignored.

Seventeenth-century optics naturalizes the eye while estranging the mind from objects. A mere screen, on which rests a blurry array of light stains, the eye no longer furnishes the observer with genuine re-presentations of visible objects. The intellect is thus compelled to decipher flat images of no inherent epistemic value, accidental effects of a purely causal process, as vague, reversed reflections of wholly independent objects. Reflecting on and trespassing the boundaries between natural and artificial, orderly and disorderly, this optical paradox (...) is a Baroque phenomenon; and it is the origin of Descartes’ celebrated doubt---whether we know anything at all.

According to Foucault, the human body is the targeted object of modern power systems. In his genealogical studies, Foucault describes the manner in which these power systems leave an imprint on the body and utilize knowledge of the body as an indirect means of exercising subtle forms of control. In recent years, several researchers have claimed that the status of the body, subsumed as it is by modern power networks, has become a means for conducting a unique political critique in (...) which the human being is viewed as an agent of oppression and freedom. This article takes a fresh look at Foucault’s notions of life and death that underpin the critical understanding the body–power relationship. While this approach recognizes the completeness of subjective structuring processes, it also enables the formulation of new insights regarding the status of the modern individual as the subject of separate and independent modes of speech and action.

Liberal democracy suffers from an internal contradiction stemming from its ideological roots and rending it from within. On the one hand its goal is to generate a system of laws and rules that maximize individual rights and liberties; on the other hand, some of its fundamental assumptions pertaining to the Subject restrict the political and social agent's existential experience to a limited threshold of speech and action. The central assumption of this article is that the main meeting point of the (...) critics of modernity, Apel and Habermas primarily, and the post-structuralists, Foucault and Deleuze, in regard to the Subject, rehabilitates liberal discourse and creates an opening for a political theory that maximizes the freedom of the individual as a structured, anti-essentialist Subject. I will show that the expansion of the concept of the self in the two streams sheds new light on the concepts of political control and liberty, and in this way extends the normative discussion of all aspects of the political agent's status in a modern democracy.

The Purūravac-cakkiravartti-katai, “The Story of Emperor Purūravas,” is a pre-modern Tamil folk telling of the ancient Urvaśī-Purūravas legend. The classical narrative of King Purūravas of the Lunar Dynasty tells about his love affair with the celestial nymph Urvaśī, their tragic separation, and final reunion. The PCK follows the classical narrative closely, but interposes a long account of other exploits of Purūravas, which do not appear in any of the Sanskrit tellings of the story. In this supplement, which I call “The (...) Tamil Life of Purūravas,” Purūravas faces a tragic chain of unavoidable events, but eventually restores his former status through meditation and devotion. A comparative examination of the two parts of the text, that is, the classical narrative and the Tamil Life, shows that the latter generates an inverted mirror image of the fundamental notions implied in the classical narrative. The outcome of this structure is a shift in the ideological tendencies of the narrative toward a local ethos and popular religious notions. The PCK is thus shown to be a field of cultural negotiations, in which opposing ideologies contend for superiority, and its structure can be regarded as a transformative mechanism applied by local and popular cultural forms to enable appropriation of classical narrative traditions.

A number of concerns have been raised about the possible future use of pharmaceuticals designed to enhance cognitive, affective, and motivational processes, particularly where the aim is to produce morally better decisions or behavior. In this article, we draw attention to what is arguably a more worrying possibility: that pharmaceuticals currently in widespread therapeutic use are already having unintended effects on these processes, and thus on moral decision making and morally significant behavior. We review current evidence on the moral effects (...) of three widely used drugs or drug types: propranolol, selective serotonin reuptake inhibitors, and drugs that effect oxytocin physiology. This evidence suggests that the alterations to moral decision making and behavior caused by these agents may have important and difficult-to-evaluate consequences, at least at the population level. We argue that the moral effects of these and other widely used pharmaceuticals warrant further empirical research and ethical analysis. (shrink)

Noradrenergic pathways are involved in mediating the central and peripheral effects of physiological arousal. The aim of the present study was to investigate the role of noradrenergic transmission in moral decision-making. We studied the effects in healthy volunteers of propranolol (a noradrenergic beta-adrenoceptor antagonist) on moral judgement in a set of moral dilemmas pitting utilitarian outcomes (e.g., saving five lives) against highly aversive harmful actions (e.g., killing an innocent person) in a double-blind, placebo-controlled, parallel group design. Propranolol (40 mg orally) (...) significantly reduced heart rate, but had no effect on self-reported mood. Importantly, propranolol made participants more likely to judge harmful actions as morally unacceptable, but only in dilemmas where harms were ‘up close and personal’. In addition, longer response times for such personal dilemmas were only found for the placebo group. Finally, judgments in personal dilemmas by the propranolol group were more decisive. These findings indicate that noradrenergic pathways play a role in responses to moral dilemmas, in line with recent work implicating emotion in moral decision-making. However, contrary to current theorising, these findings also suggest that aversion to harming is not driven by emotional arousal. Our findings are also of significant practical interest given that propranolol is a widely used drug in different settings, and is currently being considered as a potential treatment for post-traumatic stress disorder in military and rescue service personnel.

Paradefinite logics are logics that can be used for handling contradictory or partial information. As such, paradefinite logics should be both paraconsistent and paracomplete. In this paper we consider the simplest semantic framework for introducing paradefinite logics. It consists of the four-valued matrices that expand the minimal matrix which is characteristic for first degree entailments: Dunn–Belnap matrix. We survey and study the expressive power and proof theory of the most important logics that can be developed in this framework.

According to what we call the Principle of Procreative Beneficence, couples who decide to have a child have a significant moral reason to select the child who, given his or her genetic endowment, can be expected to enjoy the most well-being. In the first part of this paper, we introduce PB, explain its content, grounds, and implications, and defend it against various objections. In the second part, we argue that PB is superior to competing principles of procreative selection such as (...) that of procreative autonomy. In the third part of the paper, we consider the relation between PB and disability. We develop a revisionary account of disability, in which disability is a species of instrumental badness that is context- and person-relative. Although PB instructs us to aim to reduce disability in future children whenever possible, it does not privilege the normal. What matters is not whether future children meet certain biological or statistical norms, but what level of well-being they can be expected to have. (shrink)

BackgroundDecisions about withdrawal of life support for infants have given rise to legal battles between physicians and parents creating intense media attention. It is unclear how we should evaluate when life is no longer worth living for an infant. Public attitudes towards treatment withdrawal and the role of parents in situations of disagreement have not previously been assessed.MethodsAn online survey was conducted with a sample of the UK public to assess public views about the benefit of life in hypothetical cases (...) similar to real cases heard by the UK courts. We then evaluated these public views in comparison with existing ethical frameworks for decision-making.ResultsOne hundred and thirty participants completed the survey. The majority agreed that an infant’s life may have no benefit when well-being falls below a critical level. Decisions to withdraw treatment were positively associated with the importance of use of medical resources, the infant’s ability to have emotional relationships, and mental abilities. Up to 50% of participants in each case believed it was permissible to either continue or withdraw treatment.ConclusionDespite the controversy, our findings indicate that in the most severe cases, most people agree that life is not worth living for a profoundly disabled infant. Our survey found wide acceptance of at least the permissibility of withdrawal of treatment across a range of cases, though also a reluctance to overrule parents’ decisions. These findings may be useful when constructing guidelines for clinical practice. (shrink)

A contribution to the sixth installment of the Common Knowledge symposium “Apology for Quietism,” this article reflects on the challenges that understanding the Holocaust posed for Jews in Palestine and has posed for them in Israel. Ofer concentrates on the images of victims, fighters, and survivors as they were formulated during the last years of World War II and after the establishment of the State of Israel. Behind these images stood historical, concrete human beings who were classified according to (...) concepts supplied by Zionist and historical Jewish culture, in which activism vs. quietism had long presented major issues for debate. A narrative and typology developed of fighting heroes, victims, and survivors; Ofer questions how different these categories were from each other. In pursuit of an answer, she examines institutions in Israel for commemoration and remembrance, especially Yad Vashem, a state-established institution centering on its often-reconfigured and redesigned historical museums. Finally, this article explores the impact of immigrations and wars on the approach of Israelis to activism and quietism, with special reference to attitudes toward the Holocaust. (shrink)

We introduce a general approach for representing and reasoning with argumentation-based systems. In our framework arguments are represented by Gentzen-style sequents, attacks between arguments are represented by sequent elimination rules, and deductions are made according to Dung-style skeptical or credulous semantics. This framework accommodates different languages and logics in which arguments may be represented, allows for a flexible and simple way of expressing and identifying arguments, supports a variety of attack relations, and is faithful to standard methods of drawing conclusions (...) by argumentation frameworks. Altogether, we show that argumentation theory may benefit from incorporating proof theoretical techniques and that different non-classical formalisms may be used for backing up intended argumentation semantics.

In the twentieth century one interpretative perspective is curiously and strikingly absent: spatiality of narrative. Philosophical thought saw fundamental ontology as founded on temporality with space as decoration. Johannine inquiry has tended to follow in philosophy's temporal footsteps. However, it is plausible to assume that New Testament writers were spatially oriented while modern interpreters have been ensconced in temporal consciousness. Furthermore, as anthropology has long recognized, conceptions of space and place are central to any culture's sense of self. The undue (...) hermeneutic privileging of linearity and causality may have forced biblical texts into a temporal mode of reading that their original authors may not have intended.In understanding biblical worlds it is necessary to again explore spatiality. This essay will introduce textured spatiality as it applies to John 9. It will briefly review temporal thought and consciousness and explain how visual imagery is an essential component to the transmission and preservation of tradition. Textuality will also be used to tell the tale of the man born blind. Using the nature of Shabbat as a pivot, and a narrative juxtaposition of two contrasting Sabbath spaces, the paper will point to a possible Urcarnivalesque element in the chapter. (shrink)

The Upper Palaeolithic Revolution, sometimes called ‘the Creative Explosion’, is seen as the period when the forefathers of modern forager societies emerged. Similarly to the Industrial and Neolithic Revolutions, it represents a short time span when numerous inventions appeared and cultural changes occurred. The inventions were in the domain of technology, that is, shaping of new stone tool forms, longdistance exchange of raw materials, the use of bone, antler and ivory as well as rare minerals for the production of domestic (...) and ritual objects. Spatial analysis of ‘living floors’ indicates the presence of a kitchen area, sleeping grounds, storage facilities (in certain regions) and a discard zone. We can also detect a certain increase in social hierarchy and the presence of shamans. Body decorations indicate the appearance of personal individuality. Several hypotheses were offered as an explanation for the initiation of all these cultural changes often grouped under the term ‘modern behaviour’. It stands to reason that attributing the new successful technologies observed in the Eurasian Upper Palaeolithic to intrinsic social processes and economic innovations by local Middle Palaeolithic populations would need a better archaeological demonstration than that available today. For the time being, the emergence of Modern humans in sub-Saharan Africa, their socio-economic dynamism that caused their expansion through the Nile Valley into the Near East, and their migration along the ‘southern route’ of Asia as far as Australia, is the most plausible scenario though it still leaves much to be desired from future archaeological research.

This is an examination of Ronald Dworkin's claim that the true theory of legal practice is the theory that puts legal practice in its ‘best light’. By ‘best light’ Dworkin means a measure of desirability or goodness: the true theory of legal practice, says Dworkin, portrays the practice at its most desirable. Now why would that be the case? What's between the desirability of a theory and its truth? The article examines the reasons leading Dworkin to this strange claim. It (...) then argues that the claim is ultimately unsustainable, but also that it contains much insight about legal practice: the true theory of legal practice need not put the practice at its most desirable, but there is much between maximizing desirability and the practice's standards. Dworkin's is another important effort to explain the normative aspect of legal validity—in a way that transcends both the crudeness of natural law, and legal positivism's attempt to wash its hands of this crucial aspect of law.

Maximality is a desirable property of paraconsistent logics, motivated by the aspiration to tolerate inconsistencies, but at the same time retain from classical logic as much as possible. In this paper we introduce the strongest possible notion of maximal paraconsistency, and investigate it in the context of logics that are based on deterministic or non-deterministic three-valued matrices. We show that all reasonable paraconsistent logics based on three-valued deterministic matrices are maximal in our strong sense. This applies to practically all three-valued (...) paraconsistent logics that have been considered in the literature, including a large family of logics which were developed by da Costa's school. Then we show that in contrast, paraconsistent logics based on three-valued properly nondeterministic matrices are not maximal, except for a few special cases (which are fully characterized). However, these non-deterministic matrices are useful for representing in a clear and concise way the vast variety of the (deterministic) three-valued maximally paraconsistent matrices. The corresponding weaker notion of maximality, called premaximal paraconsistency, captures the "core" of maximal paraconsistency of all possible paraconsistent determinizations of a non-deterministic matrix, thus representing what is really essential for their maximal paraconsistency.

This paper grew as a continuation of [Sh462] but in the present form it can serve as a motivation for it as well. We deal with the same notions, all defined in 1.1, and use just one simple lemma from there whose statement and proof we repeat as 2.1. Originally entangledness was introduced, in [BoSh210] for example, in order to get narrow boolean algebras and examples of the nonmultiplicativity of c.c-ness. These applications became marginal when other methods were found and (...) successfully applied (especially Todorčevic walks) but after the pcf constructions which made their début in [Sh-g] and were continued in [Sh462] it seems that this notion gained independence.Generally we aim at characterizing the existence of strong and weak entangled orders in cardinal arithmetic terms. In [Sh462, §6] necessary conditions were shown for strong entangledness which in a previous version was erroneously proved to be equivalent to plain entangledness. In §1 we give a forcing counterexample to this equivalence and in §2 we get those results for entangledness (certainly the most interesting case). A new construction of an entangled order ends this section. In §3 we get weaker results for positively entangledness, especially when supplemented with the existence of a separating point (Definition 2.2). An antipodal case is defined in 3.10 and completely characterized in 3.11. Lastly we outline in 3.12 a forcing example showing that these two subcases of positive entangledness comprise no dichotomy. The work was done during the fall of 1994 and the winter of 1995. The second author proved Theorems 1.2, 2.14, the result that is mentioned in Remark 2.11 and what appears in this version as Theorem 2.10(a) with the further assumptionden(I)θ< μ. The first author is responsible for waving off this assumption (actually by showing that it holds in the general case), for Theorems 2.12 and 2.13 in Section 2 and for the work which is presented in Section 3.

Some have objected to human enhancement on the grounds that it violates the autonomy of the enhanced. These objections, however, overlook the interesting possibility that autonomy itself could be enhanced. How, exactly, to enhance autonomy is a difficult problem due to the numerous and diverse accounts of autonomy in the literature. Existing accounts of autonomy enhancement rely on narrow and controversial conceptions of autonomy. However, we identify one feature of autonomy common to many mainstream accounts: reasoning ability. Autonomy can then (...) be enhanced by improving people’s reasoning ability, in particular through cognitive enhancement; given how valuable autonomy is usually taken to be, this gives us extra reason to pursue such cognitive enhancements. Moreover, autonomy-based objections will be especially weak against such enhancements. As we will argue, those who are worried that enhancements will inhibit people’s autonomy should actually embrace those enhancements that will improve autonomy. (shrink)

BackgroundWhether patients in the vegetative state (VS), minimally conscious state (MCS) or the clinically related locked-in syndrome (LIS) should be kept alive is a matter of intense controversy. This study aimed to examine the moral attitudes of lay people to these questions, and the values and other factors that underlie these attitudes.MethodOne hundred ninety-nine US residents completed a survey using the online platform Mechanical Turk, comprising demographic questions, agreement with treatment withdrawal from each of the conditions, agreement with a series (...) of ethical principles and three personality tests.ResultsMore supported treatment withdrawal from VS (40.2 % agreed, 17.6 % disagreed) than MCS (20.6 %, 41.2 %) or LIS (25.3 %, 35.8 %). Agreement with treatment withdrawal was negatively correlated with religiosity (r = −0.272, P < 0.001), though showed no significant relationship with need for cognition or empathy, and only a partial association with utilitarian judgment in a standard moral dilemma. Support for treatment withdrawal was most strongly associated with endorsement of the importance of patient autonomy, dignity, suffering, best interests. Distributive justice was not given significant weight by most. Importantly, agreement with treatment withdrawal was noticeably higher when considered from a first as opposed to third person perspective for VS (Z = −6.056, P < 0.001), MCS (Z = −6.746, P < 0.001) and LIS (Z = −6.681, P < 0.001).ConclusionLay attitudes to withdrawal of treatment in brain damaged patients are largely shaped by values similar to those central to the secular ethical debate. Neither traditional values such as the sanctity of life nor utilitarian values relating to resource allocation seem to play a central role. Far greater weight is given to autonomy, which may explain why participants were far more willing to endorse withdrawal of treatment when the issue was presented in the first person, or in relation to a concrete case involving a patient’s explicit wishes. Surveys focusing on abstract cases presented in the third person may not provide an accurate picture of lay attitudes to these critical ethical questions. (shrink)

Reasoning with the maximally consistent subsets of the premises is a well-known approach for handling contradictory information. In this paper we consider several variations of this kind of reasoning, for each one we introduce two complementary computational methods that are based on logical argumentation theory. The difference between the two approaches is in their ways of making consequences: one approach is of a declarative nature and is related to Dung-style semantics for abstract argumentation, while the other approach has a more (...) proof-theoretical flavor, extending Gentzen-style sequent calculi. The outcome of this work is a new perspective on reasoning with MCS, which shows a strong link between the latter and argumentation systems, and which can be generalized to some related formalisms. As a by-product of this we obtain soundness and completeness results for the dynamic proof systems with respect to several of Dung’s semantics. In a broader context, we believe that this work helps to better understand and evaluate the role of logic-based instantiations of argumentation frameworks. (shrink)

In this paper, we investigate how data about public preferences may be used to inform policy around the use of controversial novel technologies, using public preferences about autonomous vehicles (AVs) as a case study. We first summarize the recent ‘Moral Machine’ study, which generated preference data from millions of people regarding how they think AVs should respond to emergency situations. We argue that while such preferences cannot be used to directly inform policy, they should not be disregarded. We defend an (...) approach that we call ‘Collective Reflective Equilibrium in Practice’ (CREP). In CREP, data on public attitudes function as an input into a deliberative process that looks for coherence between attitudes, behaviours and competing ethical principles. We argue that in cases of reasonable moral disagreement, data on public attitudes should play a much greater role in shaping policies than in areas of ethical consensus. We apply CREP to some of the global preferences about AVs uncovered by the Moral Machines study. We intend this discussion both as a substantive contribution to the debate about the programming of ethical AVs, and as an illustration of how CREP works. We argue that CREP provides a principled way of using some public preferences as an input for policy, while justifiably disregarding others. (shrink)

Response to commentary. We are grateful to Crockett and Craigie for their interesting remarks on our paper. We accept Crockett’s claim that there is a need for caution in drawing inferences about patient groups from work on healthy volunteers in the laboratory. However, we believe that the evidence we cited established a strong presumption that many of the patients who are routinely taking a medication, including many people properly prescribed the medication for a medical condition, have morally significant aspects of (...) their cognition and behavior modified in a way that is unintended and may sometimes be unwelcome. Crockett notes that in some cases the effects of long-term drug use may differ, sometimes markedly, from the effects of short-term use. However, if acute use of a drug affects a neural system involved in mediating moral cognition or behavior, this nevertheless provides some evidence that chronic use of the drug may affect that same system and thus have morally significant effects. It is also plausible, in some cases, that an acute moral effect would give rise to a chronic moral effect via cognitive mechanisms. ... (shrink)

Is the tendency to morally prioritize humans over animals weaker in children than adults? In two pre-registered studies (N = 622), 5- to 9-year-old children and adults were presented with moral dilemmas pitting varying numbers of humans against varying numbers of either dogs or pigs and were asked who should be saved. In both studies, children had a weaker tendency to prioritize humans over animals than adults. They often chose to save multiple dogs over one human, and many valued the (...) life of a dog as much as the life of a human. While they valued pigs less, the majority still prioritized ten pigs over one human. By contrast, almost all adults chose to save one human over even one hundred dogs or pigs. Our findings suggest that the common view that humans are far more morally important than animals appears late in development and is likely socially acquired. (shrink)

The possibility of enhancing human abilities often raises public concern about equality and social impact. This chapter aims at one particular group of technologies, cognitive enhancement, and one particular fear, that enhancement will create social divisions and possibly expanding inequalities. The chapter argues that cognitive enhancements could offer significant social and economic benefits. The basic forms of internal cognitive enhancement technologies foreseen today are pharmacological modifications, genetic interventions, transcranial magnetic stimulation, and neural implants. Cognitive enhancements can influence the economy through (...) reduction of losses, individual economic benefits, and society‐wide benefits. The strongest objection to the introduction of any enhancement technology is that it will create inequality, injustice, and unfairness. While there are clear economic and social benefits to cognitive enhancement, there exist anumber of obstacles to its development and use. One obstacle is the present system for licensing drugs and medical treatments. (shrink)

In this paper we provide a proof theoretical investigation of logical argumentation, where arguments are represented by sequents, conflicts between arguments are represented by sequent elimination rules, and deductions are made by dynamic proof systems extending standard sequent calculi. The idea is to imitate argumentative movements in which certain claims are introduced or withdrawn in the presence of counter-claims. This is done by a dynamic evaluation of sequences of sequents, in which the latter are considered ‘derived’ or ‘not derived’ according (...) to the content of the sequence. We show that decisive conclusions of such a process correspond to well-accepted consequences of the underlying argumentation framework. The outcome is therefore a general and modular proof-theoretical approach for paraconsistent and non-monotonic reasoning with argumentation systems. (shrink)

Does morality have a procedure? Unlike law, morality is arguably neither posited nor institutional. Thus, while morality undeniably prescribes various procedures, that morality itself has a procedure is less obvious. Indeed, the coexistence of procedural moral norms alongside substantive moral norms might seem paradoxical, given that they often yield contradictory prescriptions. After all, one may wonder, is morality not substantive all the way down? Nevertheless, the paper argues that morality has a “procedural branch” containing numerous norms that are themselves procedural. (...) These norms comprise what we hold are the three hallmarks of a procedural norm: second-orderness, providing reasons on how to engage with other norms, and outcome-neutrality. In this respect, morality is more like law than what one might have expected. (shrink)

Evolutionary debunking arguments are arguments that appeal to the evolutionary origins of evaluative beliefs to undermine their justification. This paper aims to clarify the premises and presuppositions of EDAs—a form of argument that is increasingly put to use in normative ethics. I argue that such arguments face serious obstacles. It is often overlooked, for example, that they presuppose the truth of metaethical objectivism. More importantly, even if objectivism is assumed, the use of EDAs in normative ethics is incompatible with a (...) parallel and more sweeping global evolutionary debunking argument that has been discussed in recent metaethics. After examining several ways of responding to this global debunking argument, I end by arguing that even if we could resist it, this would still not rehabilitate the current targeted use of EDAs in normative ethics given that, if EDAs work at all, they will in any case lead to a truly radical revision of our evaluative outlook.

Recent research on moral decision-making has suggested that many common moral judgments are based on immediate intuitions. However, some individuals arrive at highly counterintuitive utilitarian conclusions about when it is permissible to harm other individuals. Such utilitarian judgments have been attributed to effortful reasoning that has overcome our natural emotional aversion to harming others. Recent studies, however, suggest that such utilitarian judgments might also result from a decreased aversion to harming others, due to a deficit in empathic concern and social (...) emotion. The present study investigated the neural basis of such indifference to harming using functional neuroimaging during engagement in moral dilemmas. A tendency to counterintuitive utilitarian judgment was associated both with ‘psychoticism’, a trait associated with a lack of empathic concern and antisocial tendencies, and with ‘need for cognition’, a trait reflecting preference for effortful cognition. Importantly, only psychoticism was also negatively correlated with activation in the subgenual cingulate cortex (SCC), a brain area implicated in empathic concern and social emotions such as guilt, during counterintuitive utilitarian judgments. Our findings suggest that when individuals reach highly counterintuitive utilitarian conclusions, this need not reflect greater engagement in explicit moral deliberation. It may rather reflect a lack of empathic concern, and diminished aversion to harming others. (shrink)
