This research assessed how the performance and team skills of three-person teams working with an Intelligent Team Tutoring System on a virtual military surveillance task were affected by feedback privacy, participant role, task experience, prior team experience, and teammate familiarity. Previous work in Intelligent Tutoring Systems has focused on outcomes for task skill training for individual learners. As research extends into intelligent tutoring for teams, both task skills and team skills are necessary for good team performance. This work includes a (...) brief review of previous research on ITTSs, feedback, teams, and teamwork, including the recounting of two categories of a framework of teamwork performance, Communication and Cognition, which are relevant to the present study. This research examines the effects of an intelligent agent, as well as features of the team, its members, and the task being undertaken, on team communication and team situation awareness. Thirty-seven teams of three participants, each at their own computer running a multiplayer surveillance simulation, were given just-in-time private or public performance feedback during four 5-min trials. In the fourth trial, two of the three participants switched roles. Feedback type, teamwork experience, and teammate familiarity had no statistically significant effect on communication or team situation awareness. However, higher levels of role experience and task experience showed significant and medium-sized effects on communication performance. Results, based on performance data and structured interview responses, also revealed areas of improvement in future feedback design and a potential benchmark for feedback frequency in an action-oriented serious game-based ITTS. Among the conclusions are six design objectives for future ITTSs, establishing a foundation for future research on designing effective ITTSs that train interpersonal skills to nascent teams.

This paper is a reply to Stephen Davis' ‘A Defence of the Free Will Defence’. With the aid of some elementary modal logic, some of the inner workings of Davis’ argument are explored, and the nature of the opposition of the Davis argument to the Mackie thesis is made plainer. It is concluded herein that while the Davis argument is interesting and illuminating, it is not conclusive, as Davis appears to think, and that the burden of proof remains on (...) the opponent of the Mackie thesis, i.e., the Free Will Defence defender.

Gaston Bachelard distinguishes the radical novelty and newness of the imagination from pre-existing sensory impressions. In this article, I explore Bachelard's connections between time, the imagined image and poetic form, and I consider their implications for the cinema. Concentrating my analysis on Ildikó Enyedi's Testről és lélekről/ On Body and Soul — a film that alternates between doubled worlds, depictions of human and animal life — I draw out the temporality and the diversity of Bachelard's imagined images. Bringing Bachelard's instant, (...) vertical time and the crystalline to bear on Enyedi's film, I argue that, under the pretext of sleep, rest and dreaming, On Body and Soul engages the temporality and attentiveness of the Bachelardian imagination, together with its poetic effects.

While in the movies or reading a novel, how can we feel terrified by monsters, ghosts, and fictional serial killers? And how can we feel sad or outraged by depictions of cruelty? After all, we know that the imagined threats that we fear do not exist and, therefore, pose no real threat to us; and we know that the instances of cruelty that bring tears to our eyes have not happened. And yet, the fear, the sadness, or the outrage experienced (...) in our imaginations feels very real. This is the so-called paradox of "fictional emotions." This and related paradoxes have become recalcitrant problems for a purely representational approach to the imagination that tries to accommodate the imagination in a belief-desire psychology, explaining our imaginings as mental states that are similar to beliefs or desires in some ways but not others—as "quasi-beliefs" or "quasi-desires." This representational approach can be seen, for example, in Kendall Walton's influential account of the imagination as "make-believe," or in Shaun Nichols and Stephen Stich's boxological account of the imagination as a "pretend box," which is in close interaction with the suspiciously similar "belief box".

The incorporation of neural-based technologies into psychiatry offers novel means to use neural data in patient assessment and clinical diagnosis. However, an over-optimistic technologisation of neuroscientifically-informed psychiatry risks the conflation of technological and psychological norms. Neurotechnologies promise fast, efficient, broad psychiatric insights not readily available through conventional observation of patients. Recording and processing brain signals provides information from ‘beneath the skull’ that can be interpreted as an account of neural processing and that can provide a basis to evaluate general behaviour (...) and functioning. But it ought not to be forgotten that the use of such technologies is part of a human practice of neuroscience informed psychiatry. This paper notes some challenges in the integration of neural technologies into psychiatry and suggests vigilance particularly in respect to normative challenges. In this way, psychiatry can avoid a drift toward reductive technological approaches, while nonetheless benefitting from promising advances in neuroscience and technology. (shrink)

Legitimate political authority is often said to involve a “right to rule,” which is most plausibly understood as a Hohfeldian moral power on the part of the state to impose obligations on its subjects (or otherwise to change their normative situation). Many writers have taken the state’s moral power (if and when it exists) to be a correlate, in some sense, of an obligation on the part of the state’s subjects to obey its directives. Thus legitimate political authority is said (...) to entail a general obligation to obey the law, and a general obligation to obey the law is said to entail legitimate political authority. With some version of this idea in mind, many writers attempt to establish full (or partial) legitimate political authority by first arguing for the intermediate conclusion that there exists a general (or partial) obligation to obey the law. This article argues that such a strategy is fundamentally mistaken, because while legitimate authority does indeed entail an obligation to obey the law, an obligation to obey the law does not, in and of itself, entail legitimate authority. This can be referred to as “the reverse entailment problem.” To avoid this problem, a theory of political authority must argue directly for the existence of the appropriate kind of moral power on the part of the state. This article argues for the “value-based” conception of a moral power, which states, very roughly, that one person holds a power over another if there is sufficient value in the former possessing the capacity intentionally to impose an obligation on the latter (or otherwise to change her normative situation). This seemingly simple understanding of a moral power gives rise to surprisingly strong adequacy conditions on what can count as an acceptable theory of legitimate political authority, and these conditions decisively rule out most of the standard theories in the literature.

Evolutionary psychology and social constructionism are widely regarded as fundamentally irreconcilable approaches to the social sciences. Focusing on the study of the emotions, we argue that this appearance is mistaken. Much of what appears to be an empirical disagreement between evolutionary psychologists and social constructionists over the universality or locality of emotional phenomena is actually generated by an implicit philosophical dispute resulting from the adoption of different theories of meaning and reference. We argue that once this philosophical dispute is recognized, (...) it can be set to the side. When this is done, it becomes clear that the two approaches to the emotions complement, rather than compete with, one another. (shrink)

The concept of representation has become almost inextricably bound to the concept of symbol systems. the concepts is nowhere more prevalent than in descriptions of "internal representations." These representations are thought to occur in an internal symbol system that allows the brain to store and use information. In this paper we explore a different approach to understanding psychological processes, one that retains a commitment to representations and computations but that is not based on the idea that information must be stored (...) and manipulated in symbol systems. In particular, we suggest that the notion of a symbol system as currently understood construes psychological processes in terms of a specific type of computational system, in which a control function "reads," "interprets," and manipulates discrete entities called "symbols." We argue that other types of computational systems may provide a more appropriate characterization of psychological processes. One implication of our argument is the need to consider the constraints placed on computational theories in psychology by the nature of the computing device itself, the human brain. Perhaps surprisingly, this implication leads us to the conclusion that a "functionalist" conception of psychological processes (discussed below) does not entail that physiology is irrelevant to psychology, as has been maintained by prominent adherents of the symbol-systems approach.

The analysis of data from electronic health records aspires to facilitate healthcare efficiencies and biomedical innovation. There are also ethical, legal and social implications from the handling of sensitive patient information. The paper explores the concerns, expectations and implications of the National Health Service England care.data programme: a national data sharing initiative of linked electronic health records for healthcare and other research purposes. Using Nissenbaum’s contextual integrity of privacy framework through a critical Science and Technology Studies lens, it examines the (...) way technologies and policies are developed to promote sustainability, governance and economic growth as the de facto social values, while reducing privacy to an individualistic preference. The state, acting as a new, central data broker reappropriates public ownership rights and establishes those information flows and transmission principles that facilitate the assetisation of NHS datasets for the knowledge economy. Various actors and processes from other contexts attempt to erode the public healthcare sector and privilege new information recipients. However, such data sharing initiatives in healthcare will be resisted if we continue to focus only on the monetary and scientific values of these datasets and keep ignoring their equally important social and ethical values.

ABSTRACTDespite being held in something approaching universal esteem for its capacity to promote prosocial behavior and inhibit antisocial behavior, empathy has recently become the recipient of strong criticism from some of today’s leading academics. Two of the more high-profile criticisms of empathy have come from philosopher Jesse Prinz and psychologist Paul Bloom, each of whom challenges the view that empathy has an overall beneficial influence on human behavior. In this essay, I discuss the basis of their criticisms as well as (...) why I am not compelled by their arguments to believe that empathy does more harm than good. In the process of responding to empathy’s critics, I discuss the important role that empathy plays in our moral lives. I argue that, rather than employing rational considerations to minimize the role that empathy plays in our moral and political judgments, such considerations are put to better use by expanding empathy when conducive to the common good and suppressing it when it opposes th...

George Molnar came to see that the solution to a number of the problems of contemporary philosophy lay in the development of an alternative to Hume's metaphysics, with real causal powers at its centre. Molnar's eagerly anticipated book setting out his theory of powers was almost complete when he died, and has been prepared for publication by Stephen Mumford, who provides a context-setting introduction.

Commentators who lament that Kant offers no concrete guidelines for how to set up an ethical community typically neglect Kant’s claim in Religion that the ethical state of nature can transform into an ethical community only by becoming a people of God—i.e., a religious community, or “church.” Kant’s argument culminates by positing four categorial precepts for church organization. The book’s next four sections can be read as elaborating further on each precept, respectively. Kant repeatedly warns against using religious norms to (...) control people. Accordingly, he explicitly forbids the true church from adopting any standard form of political governance; it must aim to be radically non-political. Nevertheless, churches organized according to Kant’s non-coercive theocratic model contribute something essential to the ultimate political goal of achieving perpetual peace and an end to war: by approaching the ultimate ethical goal, the true church offers an antidote to normative fragmentation.

Agonism emerged three decades ago as an assault on the overemphasis in political theory on justice and consensus. It has now become the norm. But its character and relation to core values of democracy are not as unproblematic today as is often thought, an issue that becomes more pressing as contemporary politics increasingly seem locked into notions of unrelenting conflict between “friends” and “enemies.” This essay traces alternative ontological roots and ethical implications of agonism, distinguishing between “imperializing” and “tempered” modes. (...) The former, exemplified in the popular Schmitt-Mouffe formulation, is shown to be fundamentally flawed in its failure to conceive politics in a fashion that does not allow the dynamic of friend–enemy to imperially trump appeals to democratic norms. In a world of insurgent white nationalism in democratic polities, this is no small fault. “Tempered” agonists, such as William Connolly and Bonnie Honig, offer ontologies where democratic norms can gain traction. Despite the admirable qualities of these alternatives, their formulations are nevertheless not fully persuasive. The difficulty lies in their underarticulated accounts of equality. I suggest an alternative formulation of agonism that embraces a central role for the idea of the moral equality of voice, a value that resides in the seam between notions of difference, resistance, and conflict emphasized by agonists, on the one hand, and the idea of fairness emphasized by notions of democratic justice, on the other.

It is commonly thought that disability is a harm or “bad difference” because having a disability restricts valuable options in life.

Our aim in this article is to explain why our view avoids inconsistency, to challenge Crawley's positive defense of the Options Argument, and to (...) suggest that this general line of reasoning employs a double standard.

LeMans’s gontological argument aims to prove the non-existence of God on the basis that it is possible to conceive of a being that is greater than any actual thing. If God were actual, then it would be possible to conceive of something greater than God. As this is not possible, God does not exist.

In this paper I consider two kinds of approaches that philosophers have used to defend free will against psychologist Daniel Wegner’s claim that neuroscience research indicates that consciousness does not have any causal power over our actions. On the one hand, Eddy Nahmias relies heavily on empirical arguments to challenge Wegner’s conclusions. In contrast, Daniel Dennett employs a conceptual argument based on the idea that Wegner is operating under a mistaken notion of self. After ultimately rejecting the defenses of free (...) will given by both Nahmias and Dennett, I conclude by assessing whether either of the types of approaches taken by these philosophers might eventually yield a viable defense of free will in light of the challenges posed by contemporary neuroscience.

Encyclopedia article on the meaning of 'ought'.

In 1997, the Nobel Prize-winning novelist J. M. Coetzee, invited to Princeton University to lecture on the moral status of animals, read a work of fiction about an eminent novelist, Elizabeth Costello, invited to lecture on the moral status of animals at an American college. Coetzee's lectures were published in 1999 as The Lives of Animals, and reappeared in 2003 as part of his novel Elizabeth Costello; and both lectures and novel have attracted the critical attention of a number of (...) influential philosophers--including Peter Singer, Cora Diamond, Stanley Cavell, and John McDowell. In The Wounded Animal, Stephen Mulhall closely examines Coetzee's writings about Costello, and the ways in which philosophers have responded to them, focusing in particular on their powerful presentation of both literature and philosophy as seeking, and failing, to represent reality--in part because of reality's resistance to such projects of understanding, but also because of philosophy's unwillingness to learn from literature how best to acknowledge that resistance. In so doing, Mulhall is led to consider the relations among reason, language, and the imagination, as well as more specific ethical issues concerning the moral status of animals, the meaning of mortality, the nature of evil, and the demands of religion. The ancient quarrel between philosophy and literature here displays undiminished vigor and renewed significance. (shrink)

Can we talk meaningfully about God? The theological movement known as Grammatical Thomism affirms that religious language is nonsensical, because the reality of God is beyond our capacity for expression. Stephen Mulhall critically evaluates the claims of this movement (as exemplified in the work of Herbert McCabe and David Burrell) to be a legitimate inheritor of Wittgenstein's philosophical methods as well as Aquinas's theological project. The major obstacle to this claim is that Grammatical Thomism makes the nonsensicality of religious (...) language when applied to God a touchstone of Thomist insight, whereas 'nonsense' is standardly taken to be solely a term of criticism in Wittgenstein's work. Mulhall argues that, if Wittgenstein is read in the terms provided by the work of Cora Diamond and Stanley Cavell, then a place can be found in both his early work and his later writings for a more positive role to be assigned to nonsensical utterances--one which depends on exploiting an analogy between religious language and riddles. And once this alignment between Wittgenstein and Aquinas is established, it also allows us to see various ways in which his later work has a perfectionist dimension--in that it overlaps with the concerns of moral perfectionism, and in that it attributes great philosophical significance to what theology and philosophy have traditionally called 'perfections' and 'transcendentals', particularly concepts such as Being, Truth, and Unity or Oneness. This results in a radical reconception of the role of analogous usage in language, and so in the relation between philosophy and theology. (shrink)

It is hard to argue with the proposition that value for money should guide health spending. However, even after decades of development, economic evaluation is still a work in progress. As applied, it deals poorly with issues of social justice, ageing and end of life issues; cases involving small numbers—such as decisions about orphan drugs—are also contested. Unfortunately, differences in incremental cost-effectiveness ratios are presented with a degree of precision which contributes to an ‘illusion of validity’.1 Nobel Laureate Amartya Sen (...) has suggested that ‘when all the requirements of ubiquitous market-centred evaluation have been incorporated into the procedures of cost–benefit analysis, it is not so much a discipline as a daydream’.2 As with any approach to public decision making, the use of economic evaluation rests on an implicit social licence, including that the decision making is fair and reasonable. Many countries have developed special policies for rare, ‘ultrarare’ or ‘orphan’ diseases to moderate the effect of a ubiquitous application of economic evaluation. The threshold for defining ‘small’ or rare is a matter of judgement and ranges between 2 and 80 per 100 000 population.3 Magalhaes challenges the ethical basis of special programmes for low incidence conditions and argues against such provisions. In this commentary, I will argue the contrary: that there are good reasons …. (shrink)

Informal logic is a method of argument analysis which is complementary to that of formal logic, providing for the pragmatic treatment of features of argumentation which cannot be reduced to logical form. The central claim of this paper is that a more nuanced understanding of mathematical proof and discovery may be achieved by paying attention to the aspects of mathematical argumentation which can be captured by informal, rather than formal, logic. Two accounts of argumentation are considered: the pioneering work of (...) Stephen Toulmin [The uses of argument, Cambridge University Press, 1958] and the more recent studies of Douglas Walton, [e.g. The new dialectic: Conversational contexts of argument, University of Toronto Press, 1998]. The focus of both of these approaches has largely been restricted to natural language argumentation. However, Walton’s method in particular provides a fruitful analysis of mathematical proof. He offers a contextual account of argumentational strategies, distinguishing a variety of different types of dialogue in which arguments may occur. This analysis represents many different fallacious or otherwise illicit arguments as the deployment of strategies which are sometimes admissible in contexts in which they are inadmissible. I argue that mathematical proofs are deployed in a greater variety of types of dialogue than has commonly been assumed. I proceed to show that many of the important philosophical and pedagogical problems of mathematical proof arise from a failure to make explicit the type of dialogue in which the proof is introduced.

Lately I've been giving a great deal of thought to the nature of human (and other organic) abilities. In part, this is connected to my recent research into multiple personality and the need to explain, not only the partitioning of abilities and skills among alternate personalities, but also the enhanced levels of functioning that some of them exhibit (and for that matter, the exceptional performances of "nonmultiples" in hypnotic and other sorts of dissociative states). My interest in this topic is (...) also connected to my ongoing study of savants and prodigies, who apparently have much to teach us about the limits (and perhaps also the latency) of human abilities. At bottom, I suppose, it connects with my general and longstanding concern with problems of psychological explanation, particularly in light of the gross inadequacies of trendy computational theories of the mind.
