Thomas Hobbes’s infamously severe accounts of the phenomenon of laughter earned the condemnation of such varied readers as Francis Hutcheson and Friedrich Nietzsche, and he has maintained his reputation as an enemy of humor among contemporary scholars. A difficulty is raised by the fact that Hobbes makes ample use of humor in his writings, displaying his willingness to evoke in his readers what he appears to condemn. This article brings together Hobbes’s statements on laughter and comedic writing with examples of (...) his own humorous rhetoric to show that Hobbes understands laughter as a species of insult, but that there are conditions under which humor can be made to serve the cause of peace. Drawing on evidence from across Hobbes’s works, and in particular from an understudied discussion of “Vespasian’s law” in the Six Lessons, this essay theorizes the conditions under which Hobbes found witty contumely to be conducive to peace. On this reading, Hobbes models the discreet use of humorous rhetoric in defense of peace, a defense that will be ongoing even after the commonwealth has been founded. Hobbes offers insight into how we can remain attuned to laughter’s inegalitarian tendencies without foregoing the equalizing potential to be found in laughing at ourselves and at those who think too highly of themselves.

A body schema is an agent's model of its own body that enables it to act on affordances in the environment. This paper presents a body schema system for the Learning Intelligent Decision Agent (LIDA) cognitive architecture. LIDA is a conceptual and computational implementation of Global Workspace Theory, also integrating other theories from neuroscience and psychology. This paper contends that the ‘body schema' should be split into three separate functions based on the functional role of consciousness in Global Workspace Theory. (...) There is (1) an online model of the agent's effectors and effector variables (Current Body Schema), (2) a long-term, recognitional storage of embodied capacities for action and affordances (Habitual Body Schema), and (3) "dorsal" stream information feeding directly from early perception to sensorimotor processes (Online Body Schema). This paper then discusses how the LIDA model of the body schema explains several experiments in psychology and ethology. (shrink)

In this chapter we first elucidate the subjective flow of time particularly as developed by Husserl. We next discuss time and timescales in predictive processing. We then consider how the phenomenological analysis of time can be naturalized within a predictive processing framework. In the final section, we develop an analysis of the temporal disturbances characteristic of depression using the resources of both phenomenology and predictive processing.

A wide range of medical institutions have developed and implemented policies to mitigate the adverse consequences of conflicts of interest. These newly implemented policies, which include regulation of industry contact with physicians and hospitals, controls on gifts from industry, and greater transparency in industry sponsored activities, have generated considerable controversy.Formulating and evaluating policies in a neutral, unbiased fashion can be difficult for those personally affected. When people have a stake in an issue, they tend to process information in a selective (...) fashion that supports their personal interests, a phenomenon known as “motivated reasoning.” When decision makers with preexisting opinions are exposed to information, they are inclined to selectively use the information to arrive at conclusions that justify their prior beliefs. When confronted with information that contradicts existing views, people evaluate it with greater skepticism. Additionally, once decision makers have reached a decision, they are likely to evaluate subsequent evidence in a biased manner that supports their decision. (shrink)

The multiplicity of deubiquitinating enzymes (DUBs) encoded by vertebrate genomes is partly attributable to whole genome duplication events that occurred early in chordate evolution. By surveying the literature for the largest family of DUBs (the ubiquitin-specific proteases), extensive functional redundancy for duplicated genes has been confirmed as opposed to singletons. Dramatically conflicting results have been reported for loss of function studies conducted through RNA interference as opposed to inactivating mutations, but the contradictory findings can be reconciled by a recently proposed (...) compensatory mechanism involving nonsense-mediated RNA degradation. Duplicated genes are often inactivated to become pseudogenes, and it is proposed that such is the fate of the USP15 gene of zebrafish, a commonly used model system. As it is reviewed here, these observations have implications not only for the interpretation of model system phenotypes but also for therapeutic interventions designed to target DUBs. (shrink)

Physicians are affected by the conflict of interest (COI) policies they help formulate. This study examines whether physicians evaluate these policies impartially. One hundred and seventy-nine physicians, 224 financial advisors, and 1,430 members of the general public evaluated the fairness and efficacy of a COI policy in either a medical or financial context. Physicians were more critical of the medical COI policy compared to a financial COI policy, while financial professionals displayed the reverse pattern and control respondents rated both policies (...) similarly. This suggests a bias against COI policies by those who will be directly affected. (shrink)

ABSTRACT Medical AID organisations such as Médecins Sans Frontières receive several requests from individuals and international academic institutions to conduct research at their implementation sites in Africa. Do AID agencies have an ethical duty to comply with research requests? In this paper we respond to the views and constructed theories (albeit unfounded) of one such researcher, whose request to conduct research at one of our sites in the Democratic Republic of Congo was turned down.

In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental theory regarding its phenomenal aspect. There is an “explanatory gap” between our scientific knowledge of functional consciousness and its “subjective,” phenomenal aspects, referred to as the “hard problem” of consciousness. The phenomenal aspect of consciousness is the first-person answer to “what it’s like” question, and it (...) has thus far proved recalcitrant to direct scientific investigation. Naturalistic dualists argue that it is composed of a primitive, private, non-reductive element of reality that is independent from the functional and physical aspects of consciousness. Illusionists, on the other hand, argue that it is merely a cognitive illusion, and that all that exists are ultimately physical, non-phenomenal properties. We contend that both the dualist and illusionist positions are flawed because they tacitly assume consciousness to be an absolute property that doesn’t depend on the observer. We develop a conceptual and a mathematical argument for a relativistic theory of consciousness in which a system either has or doesn’t have phenomenal consciousness with respect to some observer. Phenomenal consciousness is neither private nor delusional, just relativistic. In the frame of reference of the cognitive system, it will be observable and in other frame of reference it will not. These two cognitive frames of reference are both correct, just as in the case of an observer that claims to be at rest while another will claim that the observer has constant velocity. Given that consciousness is a relativistic phenomenon, neither observer position can be privileged, as they both describe the same underlying reality. Based on relativistic phenomena in physics we developed a mathematical formalization for consciousness which bridges the explanatory gap and dissolves the hard problem. Given that the first-person cognitive frame of reference also offers legitimate observations on consciousness, we conclude by arguing that philosophers can usefully contribute to the science of consciousness by collaborating with neuroscientists to explore the neural basis of phenomenal structures.

Across various fields it is argued that the self in part consists of an autobiographical self-narrative and that the self-narrative has an impact on agential behavior. Similarly, within action theory, it is claimed that the intentional structure of coherent long-term action is divided into a hierarchy of distal, proximal, and motor intentions. However, the concrete mechanisms for how narratives and distal intentions are generated and impact action is rarely fleshed out concretely. We here demonstrate how narratives and distal intentions can (...) be generated within cognitive agents and how they can impact agential behavior over long time scales. We integrate narratives and distal intentions into the LIDA model,and demonstrate how they can guide agential action in a manner that is consistent with the Global Workspace Theory of consciousness. This paper serves both as an addition to the LIDA cognitive architecture and an elucidation of how narratives and distal intention emerge and play their role in cognition and action. (shrink)

Epistemological accounts that make use of a safety condition on knowledge, historically, face serious problems regarding beliefs that are necessarily true. This is because necessary truths are true in all possible worlds, so such beliefs can be safe even when the bases for the beliefs are epistemically problematic. The existence of such problematically safe beliefs would undermine a major motivation for the condition itself: the ability to evaluate how well a belief tracks the truth. In this paper, we’ll argue that (...) incorporating impossible worlds into the evaluation of beliefs solves this problem, but only if the relevant account of impossible worlds entails that many impossible worlds are incredibly similar to the actual world. Further, we’ll argue that, as a result of including impossible worlds, some philosophical beliefs are unsafe, and many more are potentially unsafe. But, we argue, even if this is the case, we can still make philosophical progress. (shrink)

Interest in a hydrogen economy has grown significantly in the past decade. However, the success of old technologies that are being re-engineered to work on hydrogen, as well as the creation of new hydrogenbased technologies, hinges upon public interest in and demand for such technologies. With increasing investments in the research and development of hydrogen technologies, there exists a need to monitor public attitudes toward hydrogen to ensure its success as an alternative energy carrier. To address this need, two surveys (...) were conducted. The results of the first survey give insights about how colored information influences the public acceptance of hydrogen, and the results of the second survey elucidate what trade-offs the public is willing to accept during the transition to a hydrogen economy. Furthermore, the research highlights how hydrogen knowledge and acceptance differ among age, education, and gender groups. (shrink)

Background: There has for some time now been recognition that there was a relationship between exceptional creative talent and mental disorder. The works of Andreasen (2008) and others in this area have been very significant. However, most of the research has been carried out in USA and Europe. Very little has come out of Africa on the subject. Aim : To survey the beliefs of different groups within an African society, concerning the possibility of a relationship between creative talent and (...) mental disorder. To assess creativity within a community of people with a formal diagnosis of mental disorder. Materials and Methods: Some of the mythology of the Yoruba was examined for content, concerning the behaviour of certain notable individuals and the existence of psychopathology based on modern-day criteria. The beliefs of members of the general public and mental health professionals concerning the existence of a relationship between creative talent and psychopathology were surveyed using a questionnaire designed for the project. A sample of patients with formal diagnoses of affective disorder or schizophrenia drawn from two units, the Lagos State University Teaching Hospital and the Federal Neuropsychiatric Hospital Yaba, were assessed for 'Creativity.' Results : Although there are notable 'eccentric' figures in local mythology, the overwhelming majority of the people surveyed do not believe there is any relationship between creativity and mental illness. They however believe that engaging in creative activities helps the mentally ill to recover from illness. The mental health professionals, who were clinical psychologists and psychiatrists, had a significant minority who believed that a relationship does exist, and they also strongly assert that creative activity has a therapeutic effect for the mentally ill. A survey of in-patients diagnosed with schizophrenia and affective disorder failed to show a significant difference in the creativity of the two populations, as measured by the originality score of the Rorschach scale. The survey of patients is inconclusive, based on small sample size (ten patients with a diagnosis of schizophrenia, ten with bipolar affective disorder.). The linkage between formal mental disorder is only recognised by a significant minority of mental health professionals. A significant proportion of the population believe that creative activity aids recovery from mental illness. More research is required into this important subject in Africa. (shrink)

Decisions about targeting medical assistance in humanitarian contexts are fraught with dilemmas ranging from non-availability of basic services, to massive demographic and epidemiological shifts, and to the threat of insecurity and evacuations. Aid agencies are obliged, due to capacity constraints and competing priorities, to clearly define the objectives and the beneficiaries of their actions. That aid agencies have to set limits to their actions is not controversial, but the process of defining the limits raises ethical questions. In MSF, frameworks for (...) resource allocation are subject to constant reflection and reiteration, and perspectives are sought at all levels, from implementers at the programme level to the operational directors at headquarters. The perspectives of the programmes staff hold considerable weight as they have the knowledge and experience with particular communities to assess the degree of vulnerability and need, and are also the people who ultimately have to give explanations to beneficiaries when changes or closures are going to be instituted. Humanitarian agencies have a responsibility to ensuring that their workers are prepared to reflect on these dilemmas, and challenge the status quo when it costs lives. (shrink)

All disciplines must define their basic units and core processes. In evolutionary biology, the core process is natural selection and the basic unit of selection and adaptation is the individual. To operationalize the theory of natural selection we must count individuals, as they are the bearers of fitness. While canonical individuals have often been taken to be multicellular organisms, the hierarchy of life shows that new kinds of individuals have evolved. A variety of criteria have been used to define biological (...) individuality. Some criteria rely on the presence/absence of a particular property while others advocate an approach that reflects the process of natural selection. The plethora of approaches to classifying individuality has resulted in confusion regarding how to study individuality in a given taxon. (shrink)

Much of our everyday, embodied action comes in the form of smooth coping. Smooth coping is skillful action that has become habituated and ingrained, generally placing less stress on cognitive load than considered and deliberative thought and action. When performed with skill and expertise, walking, driving, skiing, musical performances, and short-order cooking are all examples of the phenomenon. Smooth coping is characterized by its rapidity and relative lack of reflection, both being hallmarks of automatization. Deliberative and reflective actions provide the (...) contrast case. In Dreyfus’ classic view, smooth coping is “mindless” absorption into action, being in the flow, and any reflective thought will only interrupt this flow. Building on the pragmatist account of Dewey, others, such as Sutton, Montero, and Gallagher, insist on the intelligent flexibility built into smooth coping, suggesting that it is not equivalent to automatization. We seek to answer two complementary challenges in this article. First, how might we model smooth coping in autonomous agents at fine granularity? Second, we use this model of smooth coping to show how we might implement smooth coping in artificial intelligent agents. We develop a conceptual model of smooth coping in LIDA. LIDA is an embodied cognitive architecture implementing the global workspace theory of consciousness, among other psychological theories. LIDA’s implementation of consciousness enables us to account for the phenomenology of smooth coping, something that few cognitive architectures would be able to do. Through the fine granular analysis of LIDA, we argue that smooth coping is a sequence of automatized actions intermittently interspersed with consciously mediated action selection, supplemented by dorsal stream processes. In other words, non-conscious, automatized actions often require occasional bursts of conscious cognition to achieve the skillful and flexible adjustments of smooth coping. In addition, never-conscious dorsal stream information and associated sensorimotor processes provide further online adjustments during smooth coping. To achieve smooth coping in LIDA we introduce a new module to the LIDA cognitive architecture the Automatized Action Selection sub-module. Our complex model of smooth coping borrows notions of “embodied intelligence” from enactivism and augments these by allowing representations and more detailed mechanisms of conscious control. We explore several extended examples of smooth coping, starting from basic activities like walking and scaling up to more complex tasks like driving and short-order cooking. (shrink)

Prophecies concerning an incredible End of Days for the city of Jerusalem usually make use of stories that deal with beginnings in order to build from their bits and pieces a new one, a new an better beginning. This is not the case in our prophecy, that found in Zechariah 8:4-6, which does not rearrange the order of the creation but instead promises the city days of routine and peace, days in which the weaker elements of society, the elderly and (...) the very young, will enjoy complete security and will have no need for the protection of the powerful. The prophecy yet makes subtle allusion to recent hardships, to the destruction of Jerusalem as that event is shown to us in the book of Lamentations. Unlike the fantastical prophecies, it is precisely the promise of quiet routine that threatens to awaken doubt in the dark and difficult days in which Zechariah lives, and so God announces with insistence that the promise will indeed be fulfilled.

Zachariah's description of a wonderful fornicating life for Sam and Dean captures some truth but it also misses the importance women play in shaping the Winchesters' moral decisions. In general, important women in the lives of Sam and Dean fall into three broad categories: mothers, lovers, and monsters. Sam and Dean are all too familiar with this philosophy of utilitarianism. Many times they have sacrificed relationships with women for the sake of their mission. Throughout Supernatural the objectification of the (...) Winchesters is contrasted with a happy domestic life. Sam and Dean are mistaken in thinking that their only value resides in the roles they play in the larger battles of good and evil; if they looked deeper they would see that they both would prefer a loving relationship with a woman.

Dreams of gold have accompanied human history down through the ages. Gold is a beautiful and useful metal, easily shaped and immune to rust, and from the time of the ancient Sumerian and Egyptian civilizations, it has been regarded as a precious metal from which jewels and decorative as well as everyday objects have been fashioned. Even before the concept of money turned it into one of the principal forms of exchange, gold was used as a medium of barter.Apart from (...) being of commercial and aesthetic value, gold is also a part of the stuff of fables and legends. Legendary and mythical lands where gold abounds have crowded the imaginative geography of almost all civilizations. The Bible itself, in the Book of Kings, speaks of the Mines of King Solomon, the Kingdom of Ophir, and the City of Sidon, while the prophet Zechariah observes that in the City of Tyre: “silver is heaped up like dust, and gold as the mire of the streets.” [Zachariah, 9.3].
