Spice melange is bound up with the motivations of most of the characters. Some forsake everything to gain profit through spice or to ingest it, losing themselves in the drug's intoxicating premonitions. Hedonism eventually morphed into the ethical theory of utilitarianism, which tells us to maximize the pleasure of everyone affected by our actions. This chapter explores hedonism in the Dune universe. The Baron is meant to be the immediate tangible evil in the universe of Dune. Spice has a profound (...) effect on Paul Atreides, his family, and the whole universe. Dune is a universe driven by the desires of humanity, and maybe hedonism is an appropriate way for some to live. Hedonism is richly represented throughout the Dune universe, and not even Paul is excluded from the spice's tantalizing effects. (shrink)

In this chapter, Natasha McKeever and Luke Brunning consider (sexual) jealousy in romantic life. They argue that jealousy is best understood as an emotional response to the threatened loss of love or attention, to which one feels deserving, because of a rival. Furthermore, the general value of jealousy can be questioned, and jealousy’s instrumental value needs to be balanced against a range of potential harms. They assess two potential ways of managing jealousy (which are not mutually exclusive)—firstly by adopting (...) a policy of monogamy and secondly by engaging in emotional work. Neither of these methods is easy, and neither will solve jealousy altogether, but Brunning and McKeever argue that the second strategy should be taken more seriously. (shrink)

Institutional review boards, tasked with facilitating ethical research, are often pulled in competing directions. In what we call the protection-inclusion dilemma, we acknowledge the tensions IRBs face in aiming to both protect potential research participants from harm and include under-represented populations in research. In this manuscript, we examine the history of protectionism that has dominated research ethics oversight in the United States, as well as two responses to such protectionism: inclusion initiatives and critiques of the term vulnerability. We look at (...) what we know about IRB decision-making in relation to protecting and including “vulnerable” groups in research and examine the lack of regulatory guidance related to this dilemma, which encourages protection over inclusion within IRB practice. Finally, we offer recommendations related to how IRBs might strike a better balance between inclusion and protection in research ethics oversight. (shrink)

If panpsychism is true, it suggests that consciousness pervades not only our brains and bodies but also the entire universe, prompting a reevaluation of our existential attitudes. Hence, panpsychism potentially fulfills psychological needs typically addressed by religious beliefs, such as a sense of belonging and purpose but also transcendence. The discussion is organized into two main areas: the implications of panpsychism for basic human existential needs, such as feelings of kinship, ommunication, and loneliness; and for greater existential questions relating to (...) mystical experiences including transcendent unity and alleviation of the fear of death. In conclusion panpsychism may provide a deeper meaning in life for some people but its broader impact depends on individual dispositions and the cultural context in which it is embedded. (shrink)

Implementationalism maintains that conventional, silicon-based artificial systems are not conscious because they fail to satisfy certain substantive constraints on computational implementation. In this article, we argue that several recently proposed substantive constraints are implausible, or at least are not well-supported, insofar as they conflate intuitions about computational implementation generally and consciousness specifically. We argue instead that the mechanistic account of computation can explain several of the intuitions driving implementationalism and noncomputationalism in a manner which is consistent with artificial consciousness. Our (...) argument provides indirect support for computationalism about consciousness and the view that conventional artificial systems can be conscious. (shrink)

Until recently, many philosophers took Causal Decision Theory to be more successful than its rival, Evidential Decision Theory. Things have changed, however, with a renewed concern that cases involving an extreme form of decision instability are counterexamples to CDT :392–403, 1984; Egan in Philos Rev 116:93–114, 2007). Most prominent among those cases of extreme decision instability is the Psychopath Button, due to Andy Egan; in that case, CDT recommends a seemingly absurd act that almost certainly results in your death. This (...) renewed attention to decision instability has spurned an array of modifications to and rejections of CDT. I argue, however, that the Psychopath Button and its ilk are no counterexamples to CDT. That is, given the causalist’s commitments in Newcomb Problems, they already have the tools to justify CDT’s verdict in Egan-style cases of extreme decision instability. I first argue that there is no reason to think the Psychopath Button is a counterexample to CDT; in particular, many philosophers have placed too much weight on pre-theoretic intuition in Egan-cases, and apart from pre-theoretic intuition, arguments against CDT in cases of extreme decision instability are flawed. My second claim is that the causalist can provide good reasons for following CDT in cases of extreme decision instability. I present a new case, the Two Button Defense, that highlights precisely why the causalist can reasonably follow CDT in even the Psychopath Button. CDT therefore stands as a viable decision theory, without need for modification, restriction, or rejection. (shrink)

The modern ethical framework demands informed consent for research participation that includes disclosure of material information, as well as alternatives. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (COVID-19) results in illness that often involves rapid deterioration. Despite the urgent need to find therapy, obtaining informed consent for COVID-19 research is needed. The current pandemic presents three types of challenges for investigators faced with obtaining informed consent for research participation: (1) uncertainty over key information to informed consent, (2) time (...) and pressure constraints, and (3) obligations regarding disclosure of new alternative therapies and re-consent. To mitigate consenting challenges, primary investigators need to work together to jointly promote urgent care and research into COVID-19. Actions they can take include (1) prior plan addressing ways to incorporate clinical research into clinical practice in emergency, (2) consider patients vulnerable with early deliberation on the consent process, (3) seek Legally Authorized Representatives (LARs), (4) create a collaborative research teams, (5) aim to consent once, despite evolving information during the pandemic, and (6) aim to match patients to a trial that will most benefit them. The COVID-19 pandemic both exacerbates existing challenges and raises unique obstacles for consent that require forethought and mindfulness to overcome. While research teams and clinician-investigators will need to be sensitive to their own contexts and adapt solutions accordingly, they can meet the challenge of obtaining genuinely informed consent during the current pandemic.

Chimpanzee and hunter-gatherer intergroup aggression differ in important ways, including humans having the ability to form peaceful relationships and alliances among groups. This paper nevertheless evaluates the hypothesis that intergroup aggression evolved according to the same functional principles in the two species—selection favoring a tendency to kill members of neighboring groups when killing could be carried out safely. According to this idea chimpanzees and humans are equally risk-averse when fighting. When self-sacrificial war practices are found in humans, therefore, they result (...) from cultural systems of reward, punishment, and coercion rather than evolved adaptations to greater risk-taking. To test this “chimpanzee model,” we review intergroup fighting in chimpanzees and nomadic hunter-gatherers living with other nomadic hunter-gatherers as neighbors. Whether humans have evolved specific psychological adaptations for war is unknown, but current evidence suggests that the chimpanzee model is an appropriate starting point for analyzing the biological and cultural evolution of warfare.

This paper reinvents Freire’s concepts of ‘banking education’ and ‘literacy’ within the context of the exponential growth of digital instruction in the 21st century. We argue that digital learning (i.e. online or technology enhanced) undoubtedly increases access to education globally, but also can intensify some of the worst problems described in Freire’s banking model. Accordingly, we draw from postdigital theory to scrutinize the specific structures and functions of common digital Learning Management Systems (LMSs) used by schools (i.e. Blackboard and Google (...) Classroom) to reveal a type of learning that further exacerbates the teacher-student dichotomy without liberating either party in a Freirean sense. We then use a Foucauldian lens to bring an awareness to how the accelerated use of these systems at scale, in part caused by the COVID-19 pandemic, can further entrench a data-driven, dehumanized educational experience which increases corporate profitability perhaps over the needs of students. Finally, we use these insights to modernize Freire’s concept of ‘literacy’ by building on Critical Medial Literacy (CML) in order to help educators address LMSs, (mis)information facilitated by digital content, and schooling in a (post)pandemic and postdigital world.

A dogma of contemporary normative theorizing holds that some reasons are distinctively moral while others are not. Call this view Reasons Pluralism. This essay looks at four approaches to vindicating the apparent distinction between moral and non-moral reasons. In the end, however, all are found wanting. Though not dispositive, the failure of these approaches supplies strong evidence that the dogma of Reasons Pluralism is ill-founded.

Fanatics claim that we must give up guaranteed goods in pursuit of extremely improbable Utopia. Recently, Wilkinson has defended Fanaticism by arguing that nonfanatics must violate at least one plausible rational requirement. We reject Fanaticism. We show that by taking stakes-sensitive risk attitudes seriously, we can resist the core premises in Wilkinson’s argument.

Compared to our understanding of positive prediction error signals occurring due to unexpected reward outcomes, less is known about the neural circuitry in humans that drives negative prediction errors during omission of expected rewards. While classical learning theories such as Rescorla–Wagner or temporal difference learning suggest that both types of prediction errors result from a simple subtraction, there has been recent evidence suggesting that different brain regions provide input to dopamine neurons which contributes to specific components of this prediction error (...) computation. Here, we focus on the brain regions responding to negative prediction error signals, which has been well-established in animal studies to involve a distinct pathway through the lateral habenula. We examine the activity of this pathway in humans, using a conditioned inhibition paradigm with high-resolution functional MRI. First, participants learned to associate a sensory stimulus with reward delivery. Then, reward delivery was omitted whenever this stimulus was presented simultaneously with a different sensory stimulus, the conditioned inhibitor. Both reward presentation and the reward-predictive cue activated midbrain dopamine regions, insula and orbitofrontal cortex. While we found significant activity at an uncorrected threshold for the CI in the habenula, consistent with our predictions, it did not survive correction for multiple comparisons and awaits further replication. Additionally, the pallidum and putamen regions of the basal ganglia showed modulations of activity for the inhibitor that did not survive the corrected threshold. (shrink)

Previous research has suggested that corporate social performance is positively related to firms’ attractiveness as employers. The authors propose and test an alternative model whereby job applicants’ familiarity with employers mediates the relationship between corporate social performance and organizational attractiveness. Applicants’familiarity with firms may serve as a signal of firms’suitability as employers, with more familiar firms considered more attractive. Furthermore, a firm’s overall level of corporate social activity (whether “good deeds” or “ misdeeds”) may contribute directly to firm familiarity and (...) indirectly to attractiveness through familiarity. The authors’ results support this model; firm familiarity completely mediates the relationship between corporate social performance and organizational attractiveness. (shrink)

Background Ethical and scientific principles require that clinical trials address an important question and have the resources needed to complete the study. However, there are no clear standards for review that would ensure that these principles are upheld.Methods We conducted semi-structured interviews with a convenience sample of nineteen experts in clinical trial design, conduct, and/or oversight to elucidate current practice and identify areas of need with respect to ensuring the scientific value and feasibility of clinical trials prior to initiation and (...) while ongoing. We used a priori and grounded theory to analyze the data and constant comparative method to induce higher order themes.Results Interviewees perceived determination of scientific value as the responsibility of the investigator and, secondarily, other parties who review or oversee research. Interviewees reported that ongoing trials are rarely reevaluated due to emerging evidence from external sources, evaluation is complex, and there would be value in the development of standards for monitoring and evaluating evidence systematically. Investigators, IRBs, and/or data monitoring committees (DMCs) could undertake these responsibilities. Feasibility assessments are performed but are typically inadequate; potential solutions are unclear.Conclusions There are three domains where current approaches are suboptimal and in which further guidance is needed. First, who has the responsibility for conducting scientific review, whether it be the investigator, IRB, and/or DMC is often unclear. Second, the standards for scientific review (e.g., appropriate search terms, data sources, and analytic plan) should be defined. Third, guidance is needed on the evaluation of ongoing studies in light of potentially new and evolving evidence, with particular reference to evidence from outside the trial itself. (shrink)

Although estrogens are widely considered circulating “sex steroid hormones” typically associated with female reproduction, recent evidence suggests that estrogens can act as local modulators of brain circuits in both males and females. The functional implications of this newly characterized estrogen signaling system have begun to emerge. This essay summarizes evidence in support of the hypothesis that the rapid production of estrogens in brain circuits can drive acute changes in both the production and perception of acoustic communication behaviors. These studies have (...) revealed two fundamental neurobiological concepts: (1) estrogens can be locally produced in brain circuits, independent of levels in nearby circuits and in the circulation and (2) estrogens can have very rapid effects within these brain circuits to modulate social vocalizations, acoustic processing, and sensorimotor integration. This vertebrate‐wide span of research, including vocalizing fishes, amphibians, and birds, emphasizes the importance of comparative model systems in understanding principles of neurobiology.

Psychotherapy with the use of psychedelic substances, including psilocybin, lysergic acid diethylamide (LSD), ketamine, and 3,4-methylenedioxymethamphetamine (MDMA), has demonstrated promise in treatment of post-traumatic stress disorder (PTSD), anxiety, addiction, and treatment-resistant depression. Psychedelic-assisted psychotherapy (PP) represents a unique psychopharmacological model that leverages the profound effects of the psychedelic experience. That experience is characterized by strong dependency on two key factors: participant mindset and the therapeutic environment. As such, therapeutic models that utilize psychedelics reflect the need for careful design that promotes (...) an open, flexible, trusting mindset and a supportive setting. To meet this need, the PP model is increasingly supplemented by auxiliary methods, including meditation, relaxation, visualization or spiritual practices. We suggest virtual reality (VR) as a full-spectrum tool able to capitalize on and catalyze the innately therapeutic aspects of the psychedelic experience, such as detachment from familiar reality, alteration of self-experience, augmentation of sensory perception and induction of mystical-type experiences. This is facilitated by VR’s evidenced capacity to: aid relaxation and reduce anxiety; buffer from external stimuli; promote a mindful presence; train the mind to achieve altered states of consciousness (ASC); evoke mystical states; enhance therapeutic alliance and encourage self-efficacy. While these unique VR features appear promising, VR’s potential role in PP remains speculative due to lack of empirical evidence on the combined use of VR and PP. Given the increased commercial interest in this synergy there is an urgent need to evaluate this approach. We suggest specific VR models and their role within PP protocols to inspire future direction in scientific research, and provide a list of potential disadvantages, side effects and limitations that need to be carefully considered. These include sensory overstimulation, cyber-sickness, triggering memories of past traumatic events as well as distracting from the inner experience or strongly influencing its contents. A balanced, evidence-based approach may provide continuity across all phases of treatment, support transition into and out of an ASC, deepen acute ASC experiences including mystical states and enrich the psychotherapeutic process of integration. We conclude that the potential application of VR in modulating psychedelic-assisted psychotherapy demands further exploration and an evidence-based approach to both design and implementation.

In lieu of an abstract, here is a brief excerpt of the content:The Two Creations: Metamorphoses: i.5–162, 274–415 OVID (Translated by C. Luke Soucy) The Metamorphoses of Ovid opens with the creation of the world, only to recount its destruction and recreation almost immediately after. These stories begin Ovid’s mythic anthology with a sustained exploration of the uncertain origin of humanity, the conflicts in its nature, and its uneasy place in a world governed by divine forces. The following excerpts (...) endeavor to reproduce and contextualize that exploration in a blank verse translation, preserving much of the original wordplay and employing the same number of lines as in the Latin. Before there were seas, lands, and arching skies, Throughout the whole world, nature bore one face, Which was called Chaos, an unordered, rough And tumble mass of lifeless weight, wherein Lay packed the jangling elemental seeds. 10 No Titan1 then brought sunlight to the earth, No Phoebe2 yet wrought full her lunar curve; Nor hung the Earth self-poised in swaddling air, With Amphitrite’s3 arms stretched round her banks. For though the land, the sea, and air were there, 15 The land could bear no tread, the waves no stroke, The mist no light. No being retained its shape, And each opposed with each, for in one self arion 28.3 winter 2021 1. The Sun, son of the Titan Hyperion. 2. Diana, here representing the moon. 3. A Nereid and the wife of Neptune, here representing the sea. 46 the two creations Heat battled cold, wet strove with dry, soft parts Struck against hard, and weight fought weightless things. 20 A god—and better nature—broke this strife. He tore the lands from sky and seas from land, And from the dense air split the crystal heaven. Then, after he released the separate forms, Plucked from that sightless mass, he fastened them 25 In place with common peace. Next, weightless fire Leapt up and claimed its place in vaulting heaven, With air beneath, the next by lightness placed. But denser earth sank under its own weight And drew down heavy masses by its side. 30 The circling water took hold last of all, And wrapped the solid earth inside its flow. Once he, whichever of the gods he was, Had so reduced the whole to living parts, He spun the land into a giant sphere, 35 And, to begin, lest all sides be alike, He ordered straits to stream and swell beneath The sweeping winds and clasp the circled earth. And he made springs and lakes and boundless pools, And tilted banks hemmed in by slanting streams, 40 A share of which the earth absorbs; the rest Runs to the sea, where, in a freer flood, It pounds no banks, but breaks on ocean shores. He ordered fields unrolled and valleys sunk, The forests wreathed with leaves, the mountains raised; 45 And, as two regions on both left and right Divide the sky (a fiery fifth between), So did the might of god segment its load: The same five bounds are stamped upon the earth. The middle zone is home to heat alone, 50 The outer two to snow, but those between He gave both flame and frost in measured fare, And over all, the air—as great a weight Compared to fire as water feels from earth. Ovid 47 He ordered there the mists and there the clouds, 55 And thunder, soon to frighten mortal minds, And, mixed with bolts of light, the flashing Winds. To them, the maker did not grant the air Outright (for even now, when each one blows In his own realm, the brothers quarrel so 60 They scarce withhold from shattering the world). So Eurus sought Arabian lands of dawn And Persian peaks aglow with morning rays, While near the western shores by sunset warmed, Dwells Zephyrus; and wintry Boreas seized 65 The Scythian north, while southern lands drip wet With constant clouds and rain by Auster’s hand. Above them all, the god let aether flow, A liquid lacking weight or earthly trace. Such boundaries had he scarcely set in place 70 Before the stars, which had so long been crushed In sightless gloom, began to light the sky. And... (shrink)

This article argues that history played a larger role in the thought of Gottlob Frege than has usually been acknowledged. Frege’s logical writings frequently employed statements about the past as examples that included references to historical persons. Frege also described history as a science and argued that historical propositions could support valid inferences and reliably identify historical persons and events. But Frege’s eternalist theory of reference, designed primarily for formal concepts and objects, struggled to accommodate such propositions. Identifying an objective (...) referent for the subjectivity of historical actors was particularly problematic. The article suggests that Frege’s writings are interesting for the philosopher of history for at least two reasons: first, his work is clarificatory when considering the key features that historical propositions must have to count as objective knowledge, and second, it foreshadowed the issues with historicity that analytical philosophy experienced in the twentieth century. It concludes that the problems Frege raised exposed the need for a new concept of inter-subjectivity to replace his own Platonic foundation for objectivity. (shrink)

Leon Goldstein’s critical philosophy of history has suffered a relative lack of attention, but it is the outcome of an unusual story. He reached conclusions about the autonomy of the discipline of history similar to those of R. G. Collingwood and Michael Oakeshott, but he did so from within the Anglo-American analytic style of philosophy that had little tradition of discussing such matters. Initially, Goldstein attempted to apply a positivistic epistemology derived from Hempel’s philosophy of natural science to historical knowledge, (...) but gradually formulated an anti-realistic epistemology that firmly distinguished historical knowledge of the past not only from the scientific perspective but also from fictional and common-sense attitudes to the past. Among his achievements were theories of the distinctive nature of historical evidence and historical propositions, of the constructed character of historical events, and of the relationship between historical research and contemporary culture. Taken together, his ideas merit inclusion among the most important twentieth-century contributions to the problem of historical knowledge. (shrink)

I argue that we cannot do without the foreign force paradigm to explain the cases that Andreou discusses. I suggest a both/and approach on (...) which poor self-management and diminished self-control together explain poor self-control. (shrink)

As militarization of bodies politic continues apace the world over, as military organizations again reveal themselves as primary political, economic and cultural forces in many societies, we argue that the emergent and potentially dominant form of political economic organization is a species of neo-feudal corporatism. Drawing upon Bourdieu, we theorize bodies politic as living habitus. Bodies politic are prepared for war and peace through new mediations, powerful means of public pedagogy. The process of militarization requires the generation of new, antagonistic (...) evaluations of other bodies politic. Such evaluations are inculcated via these mediations, the movement of meanings across time and space, between formerly disparate histories, places, and cultures. New mediations touch new and different aspects of the body politic: its eyes, its ears, its organs, but they are consistently targeted at the formation of dispositions, the prime movers of action.

The question of how realism and metanarratives are related in the philosophy of history does not seem to have been widely discussed. Whereas there are distinct philosophical and political senses of ‘realism’, contrasting with ‘idealism’ and ‘utopianism’ respectively, ‘metanarrative’ has a singular meaning based on Jean-François Lyotard’s sceptical definition of postmodernism as “incredulity towards metanarratives”. Lyotard defined metanarratives as philosophies of history that serve some legitimatory function, but claimed that their importance was waning. From this point of view, postmodernism can (...) be described as a species of philosophical ‘realism’. But the appearance of Francis Fukuyama’s ‘end of history’ thesis, which explicitly presented itself as a neo-Hegelian critique of political realism, suggested that Lyotard had underestimated the enduring power of metanarrative insofar as it served the interests of the American liberal-democratic capitalist order. For Jacques Derrida, Fukuyama’s work thus underlined the importance of breaking with what he called ‘onto-theological’ visions of history, although Derrida himself could be seen as authoring a metanarrative in the service of European social democracy. But if so, Derrida’s approach to metanarratives was very different in kind to contemporary religious and nationalistic versions. One way to resolve the difficulty is to make a distinction between modern ‘utopian’ and postmodern ‘realist’ versions of metanarratives. (shrink)

A familiar objection to mental state theories of well-being proceeds as follows: Describe a good life. Contrast it with one identical in mental respects, but lacking a connection to reality. Then observe that mental state theories of well-being implausibly hold both lives in equal esteem. Conclude that such views are false. Here we argue this objection fails. There are two ways reality may be thought to matter for well-being. We want to contribute to reality, and we want our experience of (...) the world to be veridical. Yet, if one accepts that reality matters in either of these ways, one must posit differences in well-being where no such differences exist. (shrink)

Wrongdoing is inescapable. We all do wrong and are wronged; and in response we often blame one another. But if blame is a defining feature of our social lives, so is ceasing to blame. We might excuse, justify, or forgive an offender; or simply let the offence go. Each mode of ceasing to blame is a social practice and each has characteristic norms that influence when and how we do it, as well as how it’s received. We argue that how (...) we relinquish blame, and how effective we are, depends on many circumstances only partially within our control. Like any norm-governed practice, one can do it well or poorly, appropriately or inappropriately, successfully or unsuccessfully. To successfully participate in a practice, one’s action must be done for the right reasons and secure uptake. We argue that social and material circumstances can compromise one’s ability to effectively cease to blame in the manner one prefers. But if one can fail, then one can lack access to particular ceasing to blame practices if one is regularly prevented from effectively relinquishing blame. However, uncooperative social and material circumstances do not only arise by chance. Our central argument is that circumstances of oppression can systematically compromise one’s ability and opportunities to effectively perform a variety of ceasing to blame practices. This deprivation is an insidious facet of oppression that is neglected both in theories of oppression and of forgiveness but which has significant implications for how we understand the power and purpose of forgiveness.

Appropriate concerns about cost and unequal access to healthcare have resulted in the creation of powerful managed networks seeking to share the risks of high healthcare costs among plans, providers, and patients. Much to their credit, these managed networks have slowed the rise in healthcare spending by as much as 44% in markets with high HMO penetration. However, whether these savings will materially improve access and quality remains to be seen.

This study looked at personality trait and personality disorder correlates of self-rated altruism. In two studies over 4,000 adult British managers completed a battery of tests including a ‘bright side’ personality trait measure ; a ‘dark side’/disorders measure, and a measure of their Motives and Values which included Altruism. The two studies showed similar results revealing that those who were low on Adjustment but high on Interpersonal Sensitivity, Prudence and Inquisitiveness were more likely to value Altruism and be motivated to (...) commit altruistic acts which concerns helping others and creating an environment that places emphasis on customer service. Those more interested in “Getting Along” with others were more Altruistic than those more interested in “Getting Ahead” of others. Implications for the selection and management of altruistic people in a business are considered. Limitations and future directions of this research are also noted. (shrink)
