Definitions of death are often referred to as legal fictions since brain death was conceived in the mid-twentieth century. Reference to legal fiction is generally paired with bioethicists’ concern that it facilitates post-mortem tissue donation and the health system generally, by determining death earlier on the continuum of dying and availing more viable tissue and therapeutic resources for others. The author argues that spatio-legal theory, drawing from legal geography, can account for the heterogeneity of effects that the fiction has in (...) spatially managing bodies (e.g., physicians, patient, family) at the bedside. The legal fiction is produced in physicians’ socio-legal practices, coordinating decision-making according to geographies of scarcity and severable, self-contained live- and dead-bodies. The determination liminally exists between private and public, enacting a sterile, affectless ordering of bodies but administered in the spectacle of sovereign death-making, conveying authority whilst managing patient’s and family’s consents. Spatialising traces of anatamo-politics and biopolitics thereby congeal and are enacted heterogeneously in and through the legal form of the fiction, securing preferred constructions of the body in the management of mortality. These spatio-legal features of the legal fiction are described from their collision with case law and literature that document competing nomoi produced from or secreted by antinomian bodies.

How do we thrive in our behaviors and experiences? Positive neuroscience research illuminates the brain mechanisms that enable human flourishing. Supported by the John Templeton Foundation's Positive Neuroscience Project, which Martin E. P. Seligman established in 2008, Positive Neuroscience provides an intersection between neuroscience and positive psychology.In this edited volume, leading researchers describe the neuroscience of social bonding, altruism, and the capacities for resilience and creativity. Part I describes the mechanisms that enable humans to connect with one another. Part II (...) focuses on the neural mechanisms underlying the human ability and willingness to confer costly benefits on others. Part III examines the mechanisms by which human brains overcome adversity, create, and discover. Specific topics include: a newly discovered nerve type that appears to be specialized for emotional communication; the effects of parenting on the male brain; how human altruism differs from that of other primates; the neural features of extraordinary altruists who have donated kidneys to strangers; and distinctive patterns of brain wiring that endow some people with exceptional musical abilities. Accessible to a broad academic audience, from advanced undergraduates to senior scholars, these subjects have generated a fascinating and highly convergent set of ideas and results, shaping our understanding of human nature.

The debtor-creditor relation, which is at the heart of this book, sharpens mechanisms of exploitation and domination indiscriminately, since, in it, there is no distinction between workers and the unemployed, consumers and producers, working and non-working populations, between retirees and welfare recipients. They are all "debtors," guilty and responsible in the eyes of capital, which has become the Great, the Universal, Creditor.--from The Making of the Indebted Man Debt -- both public debt and private debt -- has become a major (...) concern of economic and political leaders. In The Making of the Indebted Man, Maurizio Lazzarato shows that, far from being a threat to the capitalist economy, debt lies at the very core of the neoliberal project. Through a reading of Karl Marx's lesser-known youthful writings on John Mill, and a rereading of writings by Friedrich Nietzsche, Gilles Deleuze, Félix Guattari, and Michel Foucault, Lazzarato demonstrates that debt is above all a political construction, and that the creditor/debtor relation is the fundamental social relation of Western societies.Debt cannot be reduced to a simple economic mechanism, for it is also a technique of "public safety" through which individual and collective subjectivities are governed and controlled. Its aim is to minimize the uncertainty of the time and behavior of the governed. We are forever sinking further into debt to the State, to private insurance, and, on a more general level, to corporations. To insure that we honor our debts, we are at once encouraged and compelled to become the "entrepreneurs" of our lives, of our "human capital." In this way, our entire material, psychological, and affective horizon is upended and reconfigured. How do we extricate ourselves from this impossible situation? How do we escape the neoliberal condition of the indebted man? Lazzarato argues that we will have to recognize that there is no simple technical, economic, or financial solution. We must instead radically challenge the fundamental social relation structuring capitalism: the system of debt. (shrink)

"Capital is a semiotic operator": this assertion by Félix Guattari is at the heart of Maurizio Lazzarato's _ Signs and Machines_, which asks us to leave behind the logocentrism that still informs so many critical theories. Lazzarato calls instead for a new theory capable of explaining how signs function in the economy, in power apparatuses, and in the production of subjectivity. Moving beyond the dualism of signifier and signified, _Signs and Machines_ shows how signs act as "sign-operators" that enter directly (...) into material flows and into the functioning of machines. Money, the stock market, price differentials, algorithms, and scientific equations and formulas constitute semiotic "motors" that make capitalism's social and technical machines run, bypassing representation and consciousness to produce social subjections and semiotic enslavements. Lazzarato contrasts Deleuze and Guattari's complex semiotics with the political theories of Jacques Rancière, Antonio Negri and Michael Hardt, Paolo Virno, and Judith Butler, for whom language and the public space it opens still play a fundamental role. Lazzarato asks: What are the conditions necessary for political and existential rupture at a time when the production of subjectivity represents the primary and perhaps most important work of capitalism? What are the specific tools required to undo the industrial mass production of subjectivity undertaken by business and the state? What types of organization must we construct for a process of subjectivation that would allow us to escape the hold of social subjection and machinic enslavement? In addressing these questions, _Signs and Machines_ takes on a task that is today more urgent than ever. (shrink)

While the terrorism studies literature speaks of a shape of terrorism unique to modernity, the exact nature of modern terrorism, let alone the nature of modernity or its starting point, remain much in dispute. In this article we suggest that the confusion and conflict within the literature arises from a tendency to focus on certain outward or inessential features associated with modernity. In order to truly answer the question of what makes modern terrorism modern, the question needs to be set (...) on a new footing, one which inquires into the necessary and not instrumental relationship between modernity and terrorism—i.e., that inquires into the possibility of an inner dynamic which can take us from the nature of modernity itself to terrorism. In this article we suggest that the intellectual resources for an understanding of modern terrorism in the fullest sense can be found within the preeminent nineteenth-century philosopher of the birth of the modern, G.W.F. Hegel. More specifically, through a reconstruction of Hegel’s account of the French Revolution we can uncover the possibility of understanding modern terrorism as an ontological rather than a temporal category. In other words, we can uncover resources that help us grasp what modern terrorism is, rather than in what age—with its instrumental possibilities given by, say, technology or ideology—it is found. What makes modern terrorism truly modern, we will argue, is a particular shape of self-consciousness that, Hegel shows us, stands as the deep structure of early modernity, and which contains within it an inner dynamic towards a uniquely modern shape of terrorism. While all terrorism that occurs within modernity is not modern, a truly modern terrorism can be identified. (shrink)

Current psychological theories of human causal learning and judgment focus primarily on long-run predictions: two by estimating parameters of a causal Bayes nets, and a third through structural learning. This paper focuses on people’s short-run behavior by examining dynamical versions of these three theories, and comparing their predictions to a real-world dataset.

People of faith, particularly in the Judeo-Christian tradition, worship corporately at least as often, if not more so, than they do individually. Why do they do this? There are, of course, many reasons, some having to do with personal preference and others having to do with the theology of worship. But, in this paper, we explore one reason, a philosophical reason, which, despite recent work on the philosophy of liturgy, has gone underappreciated. In particular, we argue that corporate worship enables (...) a person to come to know God better than they would otherwise know him in individual worship. (shrink)

We present a new understanding of Christ’s real presence in the Eucharist on the model of Stump’s account of God’s omnipresence and Green and Quan’s account of experiencing God in Scripture. On this understanding, Christ is derivatively, rather than fundamentally, located in the consecrated bread and wine, such that Christ is present to the believer through the consecrated bread and wine, thereby making available to the believer a second-person experience of Christ, where the consecrated bread and wine are the way (...) in which she shares attention with him. The consecrated bread and wine are then, in a sense, icons of Christ. (shrink)

Bas Van Fraassen is a nifty philosopher of science. He received his PhD in Pittsburgh in 1966, under the guidance of Adolf Grünbaum, he taught at Yale University, the university of Toronto, the University of Southern California, he has been McCosh Professor of Philosophy in Princeton, and eventually joined the department of philosophy at San Francisco State University, where he has the title of Distinguished Professor of Philosophy. He first gained attention with his book An Introduction to the Philosophy of (...) Time and Space where he tried to develop a formal theory of space and time based on the notion of causality. The book had an enormous legacy, with experts of the likes of John Earman and David Malament joining the debate. However, he achieved V.I.P. status with his classic The Scientific Image, where he defends a combination of empiricism and antirealism towards unobservable entities based on a re-definition of what the scientific enterprise is. His last achievement is the tome Scientific Representation: Paradoxes of Perspectives, where he combines his scientific empiricism with the view that theories are best thought as models or structures, rather than sets of sentences. In this interview, we talk about his philosophical influences and the birth of The Scientific Image during a journey through North-Africa, Turkey and Eastern Europe, we talk about saving the phenomena and suspending judgement over the existence of unobservable entities, living in world full of mysteries and leaving unanswerable questions unanswered, rationality and irrationality, living in a simulation, the historical interplay between theorizing and experimenting, the meaning of particle detectors for an empiricist, the unity of science and physicalism, the condemnation of Galilei by the Church, and the distinction between Appearance and Reality….

In this chapter, we argue that it’s possible to lose your faith in God by the actions of other people. In particular, we argue that spiritually violent religious trauma, where religious texts are used to shame a person into thinking themselves unworthy of God’s love, can cause a person to stop engaging in activities that sustain their faith in God, such as engaging in the worship of God. To do this, we provide an analysis of faith, worship, and love on (...) which to have faith in God is to have an attitude of worship to him; to have such an attitude of worship to God is to love him; and to love God is to desire union with him. We apply this analysis particularly to the case of LGBT Christians and their experience in the church today. (shrink)

In virtue of what are we justified in employing the rule of inference Modus Ponens? One tempting approach to answering this question is to claim that we are justified in employing Modus Ponens purely in virtue of facts concerning meaning or concept-possession. In this paper, we argue that such meaning-based accounts cannot be accepted as the fundamental account of our justification.

Many have attempted to respond to arguments for the incompatibility of freedom with divine foreknowledge by claiming that God’s beliefs about the future are explained by what the world is like at that future time. We argue that this response adequately advances the discussion only if the theist is able to articulate a model of foreknowledge that is both clearly possible and compatible with freedom. We investigate various models the theist might articulate and argue that all of these models fail.

In response to John Bishop's (2007) account of passionally caused believing, Dan-Johan Eklund (2014) argues that conscious non-evidential believing is (conceptually) impossible, that is, it's (conceptually) impossible consciously to believe that p whilst acknowledging that the relevant evidence doesn't support p's being true, for it conflicts with belief being a truth-oriented attitude, or so he argues. In this article, we present Eklund's case against Bishop's account of passionally caused believing, and we argue that it's unpersuasive, at least to those who (...) accept permissivism about evidence, that is, that it's possible for there to be more than one rational response to a given body of evidence. We do this through a novel application of a case of nurtured belief, that is, of a person holding a belief simply because she was caused to do so by her upbringing, and we use it to show exactly where Eklund's argument goes wrong. We conclude by drawing a general lesson drawn from this debate: if permissivism about evidence is true, then belief being truth-oriented is consistent with non-evidential believing being possible.

We applaud Campbell's cogent arguments for the evolution of female survival mechanisms but take issue with several key conceptual claims: the treatment of patriarchy; the implicit assumption that women are passive pawns in a male game of media exploitation; and the neglect of the possibility that media images exploit existing evolved psychological mechanisms rather than create them.

Abstract:Dwelling near Lake Superior in the Anthropocene, we uncover a greater intimacy and acquaintance with our earthly responsibilities. Thoughts wash over us like waves as our thinking ebbs and flows between the fact that we must learn to dwell here while also coming to terms with the planetary implications of our very being. That ebb and flow is presented here in a series of waves, which can be read in or out of order, in an orderly or disorderly fashion. These (...) waves crash into one another as we reflect on place, dwelling, hospitality, deep history, enchantment, wildness, and thinking itself. We discover in this mixture an invitation to think more deeply about our responsibilities by contemplating one of the other bodies with which we cohabit the earth: the deep, blue body of Lake Superior.

End-of-life disputes in Ontario are currently overwhelmingly assessed through the singular lens of patient autonomy. The current dispute resolution mechanism does not adequately consider evidence-based medical guidelines, standards of care, the patient’s best interests, expert opinion, or distributive justice. We discuss two cases adjudicated by the Consent and Capacity board of Ontario that demonstrate the over emphasis on patient autonomy. Current health care policy and the Health Care Consent Act also place emphasis on patient autonomy without considering other ethically defensible (...) factors. We argue that current policy and legislation require amendment, and unless there are measures undertaken to modify them, both the quality of care provided and the long-term capabilities of the health care system to remain publicly-funded, comprehensive and equitable, are at stake.

Can exposure to media portrayals of human violence impact an individual’s ethical decision making at work? Ethical business failures can result in enormous financial losses to individuals, businesses, and society. We study how exposure to human violence—especially through media—can cause individuals to make less ethical decisions. We present three experiments, each showing a causal link between exposure to human violence and unethical business behavior, and show this relationship is mediated by an increase in individual hostility levels as a result of (...) exposure to violence. Using observational data, we then provide evidence suggesting that this relationship extends beyond the context of our experiments, showing that companies headquartered in locations marked by greater human violence are more likely to fraudulently misstate their financial statements and exhibit more aggressive financial reporting. Combined, our results suggest that exposure to human violence has significant and real effects on an individual’s ethical decision making. (shrink)

In this response article, we challenge a core assumption that lies at the centre of a round table discussion regarding the Pharmacogenetics to Avoid Loss of Hearing trial. The round table regards a genetic test for a variant that increases the risk of deafness if a carrier is given the antibiotic gentamicin. The idea is that rapid testing can identify neonates at risk, providing an opportunity to prevent giving an antibiotic that might cause deafness. We challenge the assumption that a (...) positive test unequivocally guides antibiotic choice because, aside from the risk of deafness, all antibiotics for neonatal sepsis are equivalent. We argue that this assumption is faulty and has particularly troubling moral consequences. We claim that giving an alternative to gentamicin is potentially providing inferior treatment and thereby may increase the risk of death. Parents and doctors are faced with a terrible choice as a result of positive point-of-care testing : give gold-standard treatment and risk deafness or give second line care and risk death. While we do not indicate an answer to this choice, what we do argue is that such a deep and difficult choice is one that may make parents wish genetic testing was never undertaken, and therefore, contra some authors in the round table, provides a reason to gain specific consent for POCT.

Some scientists suggest that it might be possible to reflect a portion of incoming sunlight back into space to reduce climate change and its impacts. Others argue that such solar radiation management (SRM) geoengineering is inherently incompatible with democracy. In this article, we reject this incompatibility argument. First, we counterargue that technologies such as SRM lack innate political characteristics and predetermined social effects, and that democracy need not be deliberative to serve as a standard for governance. We then rebut each (...) of the argument’s core claims, countering that (1) democratic institutions are sufficiently resilient to manage SRM, (2) opting out of governance decisions is not a fundamental democratic right, (3) SRM may not require an undue degree of technocracy, and (4) its implementation may not concentrate power and promote authoritarianism. Although we reject the incompatibility argument, we do not argue that SRM is necessarily, or even likely to be, democratic in practice. (shrink)

College students implicitly judge interracial sex and gay sex to be morally wrong Some moral intuitions arise from psychological processes that are not fully accessible to consciousness. For instance, most people disapprove of consensual adult incest between siblings, but are unable to articulate why—they just feel that it is wrong (Haidt, 2001). More generally, there is evidence for at least two sources of moral judgment: explicit conscious reasoning and tacit intuitions, which are motivated by emotional responses (Greene et al., 2001) (...) and learned associations (Greenwald & Banaji, 1995).

Hegel’s account of international relations in the closing sections of the Grundlinien der Philosophie des Rechts (1820) has been the source of considerable philosophical confusion and anxiety. This is primarily due to the fact that Hegel leaves international law at the stage of abstract right and thus, argues that an international moral order is impossible. In his essay ‘Hegel Contra Hegel in his Philosophy of Right’ (1994) and again in his systematic commentary on the Grundlinien Modern Freedom (2001) Adriaan Peperzack (...) puts forward an innovative solution to this problem. He argues that Hegel failed to see that his own account of the transition from Abstract Right to Morality contains the solution (i.e., the appearance of the judge). In this paper I question this solution by closely examining the transition from Abstract Right to Morality. On the basis of this examination I argue that the attempt to apply this transition to Hegel’s account of international relations runs aground on the problem of punishment. (shrink)

This book stems from an examination of how Western philosophy has accounted for the foundations of law. In this tradition, the character of the “sovereign” or “lawgiver” has provided the solution to this problem. But how does the sovereign acquire the right to found law? As soon as we ask this question we are immediately confronted with a convoluted combination of jurisprudence and theology. The author begins by tracing a lengthy and deeply nuanced exchange between Derrida and Nancy on the (...) question of community and fraternity and then moves on to engage with a diverse set of texts from the Marquis de Sade, Saint Augustine, Kant, Hegel, and Kafka. These texts—which range from the canonical to the apocryphal—all struggle in their own manner with the question of the foundations of law. Each offers a path to the law. If a reader accepts any path as it is and follows without question, the law is set and determined and the possibility of dialogue is closed. The aim of this book is to approach the foundations of law from a series of different angles so that we can begin to see that those foundations are always in question and open to the possibility of dialogue.

We examine the impact of a unilateral carbon tax in developed countries, focusing on the expected size of carbon leakage and the effects on leakage of border tax adjustments. We start by analyzing the problem using a simple two-country, three-good general equilibrium model to develop intuitions. We then simulate the expected size of the effects using a new, open-source, computable general equilibrium model. We analyze the extent of emissions reductions from a carbon tax in countries that made commitments under the (...) Kyoto Protocol, the expected carbon leakage, and the effects of border tax adjustments on carbon leakage, all relative to our baseline projections for emissions. We also perform extensive sensitivity tests on the parameters of the CGE model. Finally, we consider the effects of imperfect border tax adjustments on leakage, such as global or regional schedules of border taxes. (shrink)

Business managers regularly employ metaphorical violent rhetoric as a means of motivating their employees to action. While it might be effective to this end, research on violent media suggests that violent rhetoric might have other, less desirable consequences. This study examines how the use of metaphorical violent rhetoric by business managers impacts the ethical decision making of employees. We develop and test a model that explains how the use of violent rhetoric impacts employees’ willingness to break ethical standards, depending on (...) the source of the rhetoric. The results of two experiments suggest that the use of violent rhetoric by a CEO at a competing company increases employees’ willingness to engage in ethical violations while the use of violent rhetoric by employees’ own CEO decreases their willingness to engage in unethical behavior. Furthermore, we find that participants who made less ethical decisions motivated by violent rhetoric used by a competitor’s CEO did not view their decisions as less ethical than the other participants in the experiments. The results of these studies highlight potentially harmful unintended consequences of the use of violent rhetoric, providing knowledge that should be useful to managers and academics who want to increase employee motivation without increasing a willingness to engage in unethical behavior.

Two studies demonstrate that a dispositional proneness to disgust (“disgust sensitivity”) is associated with intuitive disapproval of gay people. Study 1 was based on previous research showing that people are more likely to describe a behavior as intentional when they see it as morally wrong (see Knobe, 2006, for a review). As predicted, the more disgust sensitive participants were, the more likely they were to describe an agent whose behavior had the side effect of causing gay men to kiss in (...) public as having intentionally encouraged gay men to kiss publicly— even though most participants did not explicitly think it wrong to encourage gay men to kiss in public. No such effect occurred when subjects were asked about heterosexual kissing. Study 2 used the Implicit Association Test (IAT; Nosek, Banaji, & Greenwald, 2006) as a dependent measure. The more disgust sensitive participants were, the more they showed.. (shrink)

Conceived as a solution to clinical dilemmas, and now required by organizations for hospital accreditation, ethics committees have been subject only to small-scale studies. The wide use of ethics committees and the diverse roles they play compel study. In 1999 the University of Pennsylvania Ethics Committee Research Group (ECRG) completed the first national survey of the presence, composition, and activities of U.S. healthcare ethics committees (HECs). Ethics committees are relatively young, on average seven years in operation. Eighty-six percent of ethics (...) committees report that they play a role in ongoing clinical decision making through clinical ethics consultation. All are engaged in developing institutional clinical policy. Although 4.5% of HECs write policy on managed care, 50% of HEC chairs feel inadequately prepared to address managed care. The power and activity of ethics committees parallels the composition of those committees and the relationship of members to their institutions. The role of ethics committees across the nation in making policies about clinical care is greater than was known, and ethics committees will likely continue to play an important role in the debate and resolution of clinical cases and clinical policies.

In daily life, perceivers often need to predict and interpret the behavior of group agents, such as corporations and governments. Although research has investigated how perceivers reason about individual members of particular groups, less is known about how perceivers reason about group agents themselves. The present studies investigate how perceivers understand group agents by investigating the extent to which understanding the ‘mind’ of the group as a whole shares important properties and processes with understanding the minds of individuals. Experiment 1 (...) demonstrates that perceivers are sometimes willing to attribute a mental state to a group as a whole even when they are not willing to attribute that mental state to any of the individual members of the group, suggesting that perceivers can reason about the beliefs and desires of group agents over and above those of their individual members. Experiment 2 demonstrates that the degree of activation in brain regions associated with attributing mental states to individuals—i.e., brain regions associated with mentalizing or theory-of-mind, including the medial prefrontal cortex (MPFC), temporo-parietal junction (TPJ), and precuneus—does not distinguish individual from group targets, either when reading statements about those targets' mental states (directed) or when attributing mental states implicitly in order to predict their behavior (spontaneous). Together, these results help to illuminate the processes that support understanding group agents themselves. (shrink)

People are adept at inferring novel causal relations, even from only a few observations. Prior knowledge about the probability of encountering causal relations of various types and the nature of the mechanisms relating causes and effects plays a crucial role in these inferences. We test a formal account of how this knowledge can be used and acquired, based on analyzing causal induction as Bayesian inference. Five studies explored the predictions of this account with adults and 4-year-olds, using tasks in which (...) participants learned about the causal properties of a set of objects. The studies varied the two factors that our Bayesian approach predicted should be relevant to causal induction: the prior probability with which causal relations exist, and the assumption of a deterministic or a probabilistic relation between cause and effect. Adults’ judgments (Experiments 1, 2, and 4) were in close correspondence with the quantitative predictions of the model, and children’s judgments (Experiments 3 and 5) agreed qualitatively with this account.

In 1992, the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) passed a mandate that all its approved hospitals put in place a means for addressing ethical concerns.Although the particular process the hospital uses to address such concernsmay vary, the hospital or healthcare ethics committee (HEC) is used most often. In a companion study to that reported here, we found that in 1998 over 90% of U.S. hospitals had ethics committees, compared to just 1% in 1983, and that many (...) have some and a few have sweeping clinical powers in hospitals.

A long history of research has revealed many neurophysiological changes and concomitant behavioral impacts of sleep deprivation, sleep restriction, and circadian rhythms. Little research, however, has been conducted in the area of computational cognitive modeling to understand the information processing mechanisms through which neurobehavioral factors operate to produce degradations in human performance. Our approach to understanding this relationship is to link predictions of overall cognitive functioning, or alertness, from existing biomathematical models to information processing parameters in a cognitive architecture, leveraging (...) the strengths from each to develop a more comprehensive explanation. The integration of these methodologies is used to account for changes in human performance on a sustained attention task across 88 h of total sleep deprivation. The integrated model captures changes due to time awake and circadian rhythms, and it also provides an account for underlying changes in the cognitive processes that give rise to those effects. The results show the potential for developing mechanistic accounts of how fatigue impacts cognition, and they illustrate the increased explanatory power that is possible by combining theoretical insights from multiple methodologies.

Collaboration requires agents to coordinate their behavior on the fly, sometimes cooperating to solve a single task together and other times dividing it up into sub‐tasks to work on in parallel. Underlying the human ability to collaborate is theory‐of‐mind (ToM), the ability to infer the hidden mental states that drive others to act. Here, we develop Bayesian Delegation, a decentralized multi‐agent learning mechanism with these abilities. Bayesian Delegation enables agents to rapidly infer the hidden intentions of others by inverse planning. (...) We test Bayesian Delegation in a suite of multi‐agent Markov decision processes inspired by cooking problems. On these tasks, agents with Bayesian Delegation coordinate both their high‐level plans (e.g., what sub‐task they should work on) and their low‐level actions (e.g., avoiding getting in each other's way). When matched with partners that act using the same algorithm, Bayesian Delegation outperforms alternatives. Bayesian Delegation is also a capable ad hoc collaborator and successfully coordinates with other agent types even in the absence of prior experience. Finally, in a behavioral experiment, we show that Bayesian Delegation makes inferences similar to human observers about the intent of others. Together, these results argue for the centrality of ToM for successful decentralized multi‐agent collaboration. (shrink)

Which systems/organisms are conscious? New tests for consciousness (‘C-tests’) are urgently needed. There is persisting uncertainty about when consciousness arises in human development, when it is lost due to neurological disorders and brain injury, and how it is distributed in nonhuman species. This need is amplified by recent and rapid developments in artificial intelligence (AI), neural organoids, and xenobot technology. Although a number of C-tests have been proposed in recent years, most are of limited use, and currently we have no (...) C-tests for many of the populations for which they are most critical. Here, we identify challenges facing any attempt to develop C-tests, propose a multidimensional classification of such tests, and identify strategies that might be used to validate them. (shrink)
