In June of 2008, the International Society for Comparative Studies of Chinese and Western Philosophy (ISCWP) convened its third Constructive Engagement conference, on the theme of “Comparative Philosophy Methodology.” During the opening speeches, Prof. Dunhua ZHAO, Chair of the Philosophy Department at Peking University, challenged the conference’s participants to put forward a minimal definition of “comparative philosophy” and a statement of its methods. Based on the papers from the conference and the extensive discussion that ensued, during my closing reflections (...) at the end of the conference I offered a tentative synthesis of the conference’s conclusions. That summary has already been published on-line as part of the bi-annual ISCWP newsletter (Angle 2008). In this brief essay, I recapitulate the themes of my earlier summary and expand, in my own voice, on some of the key points. (shrink)

This book develops a novel multilevel social contract theory that, in contrast to existing theories in the liberal tradition, does not merely assume a restricted form of reasonable moral pluralism, but is tailored to the conditions of deeply morally pluralistic societies which may be populated by liberal moral agents, nonliberal moral agents, and, according to the traditional understanding of morality, nonmoral agents alike. The book draws on the history of the social contract tradition, especially the work of Hobbes, Hume, Kant, (...) Rawls, and Gauthier, as well as on the work of some of the critics of this tradition, such as Sen and Gaus. The two-level contractarian theory holds that morality in its best contractarian version for the conditions of deeply morally pluralistic societies entails Humean, Hobbesian, and Kantian moral properties. The theory defines the minimal behavioral restrictions that are necessary to ensure, compared to violent conflict resolution, mutually beneficial peaceful long-term cooperation in deeply morally pluralistic societies. The theory minimizes the problem of compliance for morally diverse societies by maximally respecting the interests of all members of society. Despite its ideal nature, the theory is, in principle, applicable to the real world and, for the conditions described, most promising for securing mutually beneficial peaceful long-term cooperation in a world in which a fully just society, due to moral diversity, is unattainable. If Rawls’ intention was to carry the traditional social contract argument to a higher level of abstraction, then the two-level contractarian theory brings it back down to earth. (shrink)

As interest in comparative effectiveness research grows, questions have emerged regarding whether it is ever acceptable to alter informed consent requirements for research when patients are randomly assigned to widely-used therapies. This paper reports on interviews with Institutional Review Board members and researchers and on focus groups with patients from Geisinger and Johns Hopkins health systems. The objective was to elicit participants' views of the acceptability of four different disclosure and authorization models for low-risk pragmatic comparative effectiveness trials of widely-used (...) therapies. Results suggest that although participants valued autonomous choice, many also believed that it was acceptable to streamline information disclosure and to use an opt-out process for eligible individuals who would prefer not to participate. This provides some preliminary evidence that relevant stakeholders find alternatives to traditional informed consent acceptable for low-risk pragmatic comparative effectiveness trials of widely-used therapies as long as a sufficient amount of choice is preserved.

We study the notion of dp-minimality, beginning by providing several essential facts about dp-minimality, establishing several equivalent definitions for dp-minimality, and comparing dp-minimality to other minimality notions. The majority of the rest of the paper is dedicated to examples. We establish via a simple proof that any weakly o-minimal theory is dp-minimal and then give an example of a weakly o-minimal group not obtained by adding traces of externally definable sets. Next we give an example of a (...) divisible ordered Abelian group which is dp-minimal and not weakly o-minimal. Finally we establish that the field of p -adic numbers is dp-minimal. (shrink)

This article goes into the intentions and motives behind De Veritate (1627), famous apologetic work by the Dutch humanist and jurisconsult Hugo Grotius (1583-1645). De Veritate will be compared with two other seminal works written by Grotius, De iure belli ac pacis (1625) and the Annotationes in Novum Testamentum (1641-1650). The focus will be on one particular aspect that comes to the fore in all three works: the way Grotius reduced the Christian faith to a minimal religion by singling (...) out the essential tenets this faith had in common with other religions. The core of Grotius’s argumentation consists in the idea that believers and, in particular, civil authorities have to distinguish between a few essential religious tenets that could be made rationally acceptable, and a set of supernatural dogmas, derived from divine revelation, that did not pass a certain, albeit very high degree of probability. As far as the second category was concerned, civil tolerance was called for. As becomes clear from contemporary correspondences, Grotius did not develop these rather controversial ideas in an intellectual vacuum. During his exile in Paris, he fostered contacts with members of the circle that formed around the French monk Marin Mersenne (1588-1648). This circle functioned as a kind of hothouse for the development of a minimal Christian creed. Members of this group saw promotion of a minimal creed as a solution to current religious controversies and the ensuing political turmoil and (civil) war, which were abhorred for their detrimental effects on the advancement of learning in the first place. On the other hand, it is also apparent that overt adherence to such an ideal was considered to be dangerous, because it would at least evoke the embarrassing and even repressive attention of the authorities in Church and government. An additional problem was that by defending such a religious stance, members of Mersenne’s circle laid themselves open to accusations of endorsing ‘rational beliefs’ like Socinianism, generally considered to be the worst heresy among all Christian denominations.

Creativity has received, and continues to receive, comparatively little analysis in philosophy and the brain and behavioural sciences. This is in spite of the importance of creative thought and action, and the many and varied resources of theories of mind. Here an alternative approach to analyzing creativity is suggested: start from the bottom up with minimally creative thought. Minimally creative thought depends non-accidentally upon agency, is novel relative to the acting agent, and could not have been tokened before the time (...) it is in fact tokened, relative to the agent in question. Thoughts that meet these three conditions—agency, psychological novelty, and modal—are what may be called cognitive breakthroughs. Even if such breakthroughs are not necessary to or definitive of richer creativity, they are indeed central to much of creativity. The minimal analysis provides a more workable explanandum for theories of creativity of varied motivation and method. (shrink)

According to one influential view, model-building in science is primarily a matter of simplifying theoretical descriptions of real-world target systems using abstraction and idealization. This view, however, does not adequately capture all types of models. Many contemporary models in the natural and social sciences – from physics to biology to economics – stand in a more tenuous relationship with real-world target systems and have a decidedly stipulative element, in that they create, by fiat, ‘model worlds’ that operate according to some (...) set of specified rules. While such models may be motivated by an interest in actual target phenomena, their validity is not – at least not primarily – to be judged by whether they constitute an empirically adequate representation of any particular empirical system. The present paper compares and contrasts three such types of models: minimal models, toy models, and exploratory models. All three share some characteristics and thus overlap in interesting ways, yet they also exhibit significant differences. It is argued that, in all three cases, modal considerations have an important role to play: by exploring the modal structure of theories and phenomena – that is, by probing possibilities in various ways – such models deepen our understanding and help us gain knowledge not only about what there is in the world, but also about what there could be.

Let NNG be the claim that necessitation is necessary for grounding, and let NSG be the claim that necessitation is sufficient for grounding. The consensus view is that grounding cannot be reduced to necessitation, and this is due to the (approximately) universally-accepted claim that NSG is false. Among deniers of NSG: grounding contingentists think NNG is also false, but they are in the minority compared to grounding necessitarians who uphold NNG. For one who would defend the claim that grounding is (...) reducible to necessitation, the task is formidable: she must defend NSG and NNG. I consider two prominent objections against NSG, and two more against NNG before developing a reductive account of grounding as minimal necessitation that avoids not only all four of the previously mentioned objections, but also an additional objection that targets minimal necessitation accounts in particular. If my arguments are compelling, then, insofar as we thereby have a strong prima facie case for thinking that grounding can be reduced to (minimal) necessitation, we have a strong prima facie case for thinking the consensus view is mistaken.

What I call the minimal notion of truth is just that which the redundancy thesis claims suffices for all legitimate purposes. I argue that the minimal notion is legitimate and useful whatever one's preferred theory of truth. I rebut some arguments against the redundancy thesis which are in effect arguments against the legitimacy of the minimal notion. Finally I compare the minimal notion with a slightly stronger notion I call the semiminimal notion, and argue that this (...) does issue a refutation of the redundancy thesis as I have defined it.

The emergence of signaling systems has been observed in numerous experimental and real-world contexts, but there is no consensus on which shared mechanisms underlie such phenomena. A number of explanatory mechanisms have been proposed within several disciplines, all of which have been instantiated as credible working models. However, they are usually framed as being mutually incompatible. Using an exemplar-based framework, we replicate these models in a minimal configuration which allows us to directly compare them. This reveals that the development (...) of optimal signaling is driven by similar mechanisms in each model, which leads us to propose three requirements for the emergence of conventional signaling. These are the creation and transmission of referential information, a systemic bias against ambiguity, and finally some form of information loss. Considering this, we then discuss some implications for theoretical and experimental approaches to the emergence of learned communication. (shrink)

What could someone represent that would enable her to track, at least within limits, others' perceptions, knowledge states and beliefs including false beliefs? An obvious possibility is that she might represent these very attitudes as such. It is sometimes tacitly or explicitly assumed that this is the only possible answer. However, we argue that several recent discoveries in developmental, cognitive, and comparative psychology indicate the need for other, less obvious possibilities. Our aim is to meet this need by describing the (...) construction of a minimal theory of mind. Minimal theory of mind is rich enough to explain systematic success on tasks held to be acid tests for theory of mind cognition including many false belief tasks. Yet minimal theory of mind does not require representing propositional attitudes, or any other kind of representation, as such. Minimal theory of mind may be what enables those with limited cognitive resources or little conceptual sophistication, such as infants, chimpanzees, scrub‐jays and human adults under load, to track others' perceptions, knowledge states and beliefs.

In this paper we will investigate different axiomatic theories of truth that are minimal in some sense. One criterion for minimality will be conservativity over Peano Arithmetic. We will then give a more fine-grained characterization by investigating some interpretability relations. We will show that disquotational theories of truth, as well as compositional theories of truth with restricted induction are relatively interpretable in Peano Arithmetic. Furthermore, we will give an example of a theory of truth that is a conservative extension (...) of Peano Arithmetic but not interpretable in it. We will then use stricter versions of interpretations to compare weak theories of truth to subsystems of second-order arithmetic. (shrink)

This book investigates the nature of the relationship between phonology and syntax and proposes a theory of Minimal Indirect Reference that solves many classic problems relating to the topic. Seidl shows that all variation across languages in phonological domain size is due to syntactic differences and a single domain parameter specific to phonology.

Abductive problems and their solutions are presented by means of justification logic. We introduce additional meta-constructions in order to generate and compare different solutions to the same abductive problem. Our approach has three advantages: (i) it makes structurally explicit the solution to an abductive problem (as it has a syntactic nature); (ii) it gives a precise meaning to the notion of evidence; (iii) it provides clear definitions and procedures for the comparison of solutions that can be adapted to different needs.

H. sapiens stands out from other primates along many social dimensions; however, none seems as prominent and important as the capacity of our species for cumulative cultural evolution or, as Tomasello calls it, “the ratchet.” Although other primate species show evidence of cultural variation, there is little evidence of cumulative cultural evolution, i.e., the gradual accumulation, modification, and refinement of traditions and skills over historical time, in any primate species other than our own. This is clearly an extremely significant component (...) of the human phenotype, responsible for our unparalleled cultural, social, political, and technological achievements. However, it remains extremely controversial what sorts of cognitive capacities are necessary to trigger cumulative cultural evolution and whether any currently proposed candidates are really distinctive of humans. Furthermore, the ratchet raises a bootstrapping problem: before complex skills and technologies are present and necessary for biological success, there appear to be few advantages to high-fidelity social learning; however, without such high-fidelity social learning, it is unclear how traditions capable of generating complex skills and technologies could arise in the first place. In this chapter, we survey relevant empirical research in comparative and developmental psychology, integrating it with a novel theoretical analysis of the bootstrapping problem to defend a hypothesis about the minimal cognitive preconditions on the ratchet.

Loop quantum gravity predicts that spatial geometry is fundamentally discrete. Whether this discreteness entails a departure from exact Lorentz symmetry is a matter of dispute that has generated an interesting methodological dilemma. On one hand one would like the theory to agree with current experiments, but, so far, tests in the highest energies we can manage show no such sign of departure. On the other hand one would like the theory to yield testable predictions, and deformations of exact Lorentz symmetry (...) in certain yet– to–be–tested regimes may have phenomenological consequences. Exposing their shortcomings, here I discuss two arguments that exemplify this dilemma, and compare them to other cases from the history of physics that share their symptoms. (shrink)

By pure calculus of names we mean a quantifier-free theory, based on the classical propositional calculus, which defines predicates known from Aristotle’s syllogistic and Leśniewski’s Ontology. For a large fragment of the theory decision procedures, defined by a combination of simple syntactic operations and models in two-membered domains, can be used. We compare the system which employs `ε’ as the only specific term with the system enriched with functors of Syllogistic. In the former, we do not need an empty name (...) in the model, so we are able to construct a 3-valued matrix, while for the latter, for which an empty name is necessary, the respective matrices are 4-valued.

Despite their many virtues, democracies suffer from well-known problems with high levels of voter ignorance. Such ignorance, one might think, leads democracies to occasionally produce bad outcomes. Proponents of epistocracy claim that allocating comparatively greater amounts of political power to citizens who possess more politically relevant knowledge may help us to mitigate the bad effects of voter ignorance. An important challenge to epistocracy rejects the claim that we can reliably identify a subset of citizens who possess more politically relevant knowledge (...) than others. Roughly put, such knowledge should involve knowledge of various politically relevant social-scientific facts. But since the social sciences are mired in controversy, it’s not clear what the politically relevant facts are. Accordingly, we cannot definitively say of some citizens that they possess more politically relevant knowledge than others. Call this the Argument from Political Disagreement. In this paper I respond to the Argument from Political Disagreement. First, I argue that it conflates social-scientific knowledge with politically relevant knowledge. Even if there were no uncontroversial social-scientific knowledge, there is much uncontroversial politically relevant knowledge. Second, I establish the importance of such non-social-scientific knowledge for political decision-making. I conclude that this knowledge constitutes the minimal body of knowledge which epistocrats need to make their case. (shrink)

In the following article I present a basic proposal that is intended to provide the ground for a broader program in which I attempt to explain and characterize the foundations of the normativity generally regarded as implicit in the notion of a "person." I intend to argue that these foundations are natural in the sense that they are derived from basic behavioral and cognitive patterns which are particularly characteristic of human beings especially during their infancy. Among these basic patterns I (...) take that known as dyadic engagement to be merely the foundational stage at which embryonic personhood emerges. Dyadic engagement is a very primitive and special form of social competence which has been identified by some cognitive developmentalists and comparative psychologists as a particular kind of sensitivity for contingencies which are experienced from the very beginning in the various processes of communicative interaction.

In this article we present a new experimental paradigm: comparative visual search. Each half of a display contains simple geometrical objects of three different colors and forms. The two display halves are identical except for one object mismatched in either color or form. The subject's task is to find this mismatch. We illustrate the potential of this paradigm for investigating the underlying complex processes of perception and cognition by means of an eye‐tracking study. Three possible search strategies are outlined, discussed, (...) and reexamined on the basis of experimental results. Each strategy is characterized by the way it partitions the field of objects into “chunks.” These strategies are: (i) Stimulus‐wise scanning with minimization of total scan path length (a “traveling salesman” strategy), (ii) scanning of the objects in fixed‐size areas (a “searchlight” strategy), and (iii) scanning of object sets based on variably sized clusters defined by object density and heterogeneity (a “clustering” strategy). To elucidate the processes underlying comparative visual search, we introduce besides object density a new entropy‐based measure for object heterogeneity. The effects of local density and entropy on several basic and derived eye‐movement variables clearly rule out the traveling salesman strategy, but are most compatible with the clustering strategy.

The repeated attempts to characterise joint action have displayed a common trend towards minimalism – whether they focus on minimal situations, minimal characterisations, cognitively minimal agents or minimal cognitive mechanisms. This trend also appears to lead to pluralism: the idea that joint action may receive multiple, equally valid characterisations. In this paper, I argue for a pluralist stance regarding joint action, although one stemming from maximalism. Starting from the description of three cases of "maximal" joint action (...) – demonstrations, deliberations and free collective improvisation – that stretch our conceptual characterisations of joint action, I introduce and defend contextual minimalism, which focuses on joint actions occurring in contexts from which the factors that typically favour successful cooperation are absent. Although maximalist as compared to the other forms of minimalism, contextual minimalism does fit the minimalist trend and its recent emphasis on specific cognitive cooperative mechanisms. (shrink)

This metatheoretical paper develops a list of new research targets by exploring particularly promising interdisciplinary contact points between empirical dream research and philosophy of mind. The central example is the MPS-problem. It is constituted by the epistemic goal of conceptually isolating and empirically grounding the phenomenal property of “minimal phenomenal selfhood,” which refers to the simplest form of self-consciousness. In order to precisely describe MPS, one must focus on those conditions that are not only causally enabling, but strictly necessary (...) to bring it into existence. This contribution argues that research on bodiless dreams, asomatic out-of-body experiences, and full-body illusions has the potential to make decisive future contributions. Further items on the proposed list of novel research targets include differentiating the concept of a “first-person perspective” on the subcognitive level; investigating relevant phenomenological and neurofunctional commonalities between mind-wandering and dreaming; comparing the functional depth of embodiment across dream and wake states; and demonstrating that the conceptual consequences of cognitive corruption and systematic rationality deficits in the dream state are much more serious for philosophical epistemology (and, perhaps, the methodology of dream research itself) than commonly assumed. The paper closes by specifying a list of potentially innovative research goals that could serve to establish a stronger connection between dream research and philosophy of mind. (shrink)

In the last 20 years, a stream of research emerged under the label of „complex problem solving“ (CPS). This research was intended to describe the way people deal with complex, dynamic, and intransparent situations. Complex computer-simulated scenarios were as stimulus material in psychological experiments. This line of research lead to subtle insights into the way how people deal with complexity and uncertainty. Besides these knowledge-rich, realistic, intransparent, complex, dynamic scenarios with many variables, a second line of research used more simple, (...) knowledge-lean scenarios with a low number of variables („minimal complex systems“, MCS) that have been proposed recently in problem-solving research for the purpose of educational assessment. In both cases, the idea behind the use of microworlds is to increase validity of problem solving tasks by presenting interactive environments that can be explored and controlled by participants while pursuing certain action goals. The main argument presented here is: both types of systems - CPS and MCS – can only be dealt with successfully if causal dependencies between input and output variables are identified and used for system control. System knowledge is necessary for control and intervention. But CPS and MCS differ in their way of how causal dependencies are identified and how the mental model is constructed; therefore, they cannot be compared directly to each other with respect to the cognitive processes that are necessary for solving the tasks. Knowledge-poor MCS tasks address only a small fraction of the cognitive processes and structures needed for knowledge-rich CPS situations. (shrink)

In Minimal Morality, I develop a multilevel social contract theory that, in contrast to existing theories in the liberal tradition, does not merely assume a restricted form of reasonable moral pluralism, but is tailored to the conditions of deeply morally pluralistic societies that may include liberal moral agents, nonliberal moral agents, and, according to the traditional understanding of morality, nonmoral agents. The theory takes its main inspiration from the moral theories of Hobbes (1651), Hume (1739/1740), and Kant (1785, 1795, (...) and 1797), and some of their contemporary followers, such as Rawls (1971) and Gauthier (1986). In its simplified form, the theory combines what I call traditional first-level morality with second-level pure instrumental morality and derives, in the form of the weak principle of universalization, a principle of conflict resolution that defines the minimal behavioral restrictions that are necessary to ensure, compared to violent conflict resolution, mutually beneficial peaceful long-term cooperation in deeply morally pluralistic societies. I argue that, despite its ideal nature, this theory is, in principle, applicable to the real world and, for the conditions described, most promising for securing mutually beneficial peaceful long-term cooperation in a world in which a fully just society, due to moral pluralism, is unattainable.

The account of causal regularities in the influential INUS theory of causation has been refined in the recent developments of the regularity approach to causation and of the Boolean methods for inference of deterministic causal structures. A key element in the refinement is to strengthen the minimality or non-redundancy condition in the original INUS account. In this paper, we argue that the Boolean framework warrants a further strengthening of the minimality condition. We motivate our stronger condition by showing, first, that (...) a rationale for strengthening the original minimality condition in the INUS theory is also applicable to our proposal to go further, and second, that the new element of the stronger condition is a counterpart to a well-established minimality condition for probabilistic causal models. We also compare the various minimality conditions in terms of the difference-making criteria they imply and argue for the criterion implied by our condition. Finally, we show that putative counterexamples to our proposal can be addressed in the same way that the Boolean theorists defend the current minimality conditions in their framework. (shrink)

Complex systems are pervasive in the world around us. Making sense of a complex system should require that a person construct a network of concepts and principles about some domain that represents key (often dynamic) phenomena and their interrelationships. This raises the question of how expert understanding of complex systems differs from novice understanding. In this study we examined individuals' representations of an aquatic system from the perspective of structural (elements of a system), behavioral (mechanisms), and functional aspects of a (...) system. Structure–Behavior–Function (SBF) theory was used as a framework for analysis. The study included participants from middle school children to preservice teachers to aquarium experts. Individual interviews were conducted to elicit participants' mental models of aquaria. Their verbal responses and pictorial representations were analyzed using an SBF‐based coding scheme. The results indicated that representations ranged from focusing on structures with minimal understanding of behaviors and functions to representations that included behaviors and functions. Novices' representations focused on perceptually available, static components of the system, whereas experts integrated structural, functional, and behavioral elements. This study suggests that the SBF framework can be one useful formalism for understanding complex systems. (shrink)

In this paper we examine the thesis that the probability of the conditional is the conditional probability. Previous work by a number of authors has shown that in standard numerical probability theories, the addition of the thesis leads to triviality. We introduce very weak, comparative conditional probability structures and discuss some extremely simple constraints. We show that even in such a minimal context, if one adds the thesis that the probability of a conditional is the conditional probability, then one (...) trivializes the theory. Another way of stating the result is that the conditional of conditional probability cannot be represented in the object language on pain of trivializing the theory. (shrink)

We consider weighted o-minimal hybrid systems, which extend classical o-minimal hybrid systems with cost functions. These cost functions are “observer variables” which increase while the system evolves but do not constrain the behaviour of the system. In this paper, we prove two main results: optimal o-minimal hybrid games are decidable; the model-checking of WCTL, an extension of CTL which can constrain the cost variables, is decidable over that model. This has to be compared with the same problems (...) in the framework of timed automata where both problems are undecidable in general, while they are decidable for the restricted class of one-clock timed automata.

This paper offers a comparative investigation of anomalous self-experiences common in schizophrenia instrument) and those of normal individuals in an intensely introspective orientation. The latter represent a relatively pure manifestation of certain forms of exaggerated self-consciousness, one facet of the disturbance of core- or minimal-self postulated as central in schizophrenia. Significant similarities with schizophrenia-like experience were found but important differences also emerged. Affinities included feelings of passivity, fading of self or world, and alienation from thoughts, feelings, or lived-body. Differences (...) involved confusion between self and world and severe dislocation or erosion of first-person perspective, qualities unique to schizophrenia. The purpose is threefold: 1, place the putatively schizophrenic experiences of self-disorder in a broader, comparative context; 2, evaluate hypotheses concerning core processes in schizophrenia; 3, orient investigation of possible pathogenetic pathways as well as psychotherapeutic interventions.

ABSTRACT Despite Institutional Review Board concerns about psychological harm arising from research participation, evidence from trauma-questionnaire research suggests that participation is typically well-tolerated by participants. Yet, it is unclear how participant experiences of in-lab trauma simulations align with IRB ethical guidelines. Thus, we compared reactions to a trauma film paradigm with reactions to a positive film task or cognitive tasks. Overall, relative to other conditions, the trauma film was well-tolerated by participants: they generally reported low-to-moderate negative emotions, moderate benefits, and (...) that participation was not worse than everyday stressors. Our results have implications for the research community in designing trauma-based research. (shrink)

Prokaryotic genomes of endosymbionts and parasites are examples of naturally evolved minimal cells, the study of which can shed light on life in its minimum form. Their diverse biology, their lack of a large set of orthologous genes and the existence of essential linage (and environmentally) specific genes all illustrate the diversity of genes building up naturally evolved minimal cells. This conclusion is reinforced by the fact that sometimes the same essential function is performed by genes from different (...) evolutionary origins. Nevertheless, all cells perform a set of life‐essential functions however different their cell machinery and environment in which they thrive. An upcoming challenge for biologists will be to discern, by studying differences and similarities in current biodiversity, how cells with reduced genomes have adapted while retaining all basic life‐supporting functions.

The paper argues that Zahavi’s defence of the self as an experiential dimension, i.e. “identified with the first-person givenness of experiential phenomena”, and of the notion of a pre-reflective minimal core self relies on an unwarranted assumption. It is assumed that awareness of the phenomenal mode of experiences of objects, i.e. what the object “feels” like for the experiencer, is comparable with, indeed entails, first-person givenness of experience. In consequence both the arguments concerning the foundational role of the pre-reflective (...) minimal core self and the explanation of the unity and identity of the self through time give rise to intractable problems.

Background: Patients in a vegetative state pose problems in diagnosis, prognosis and treatment. Currently, no prognostic markers predict the chance of recovery, which has serious consequences, especially in end-of-life decision-making. Objective: We aimed to assess an objective measurement of prognosis using advanced electroencephalography (EEG). Methods: EEG data (19 channels) were collected in 14 patients who were diagnosed to be persistently vegetative based on repeated clinical evaluations at 3 months following brain damage. EEG structure parameters (amplitude, duration and variability within quasi-stationary (...) segments, as well as the spatial synchrony between such segments and the strength of this synchrony) were used to predict recovery of consciousness 3 months later. Results: The number and strength of cortical functional connections between EEG segments were higher in patients who recovered consciousness (P < .05 – P < .001) compared with those who did not recover. Linear regression analysis confirms that EEG structure parameters are capable of predicting (P = .0025) recovery of consciousness 6 months post-injury, whereas the same analysis failed to significantly predict patient outcome based on aspects of their clinical history alone (P = .629) or conventional EEG spectrum power (P = .473). Conclusions: The result of this preliminary study demonstrates that structural strategy of EEG analysis is better suited for providing prognosis of consciousness recovery than existing methods of clinical assessment and of conventional EEG. Our results may be a starting point for developing reliable prognosticators in patients who are in vegetative state, with the potential to improve their day-to-day management, quality of life, and access to early interventions.

Research risks have to meet minimal risk requirements in order for the research to qualify for expedited ethics review, to be exempted from ethics review, or to be granted consent waivers. The definition of “minimal risk” in the Common Rule (45 CFR 46) relies on the risks-of-daily-life and risks-of-routine-tests as comparators against which research activities are assessed to meet minimal risk requirements. While either or both comparators have been adopted by major ethics codes, they have also been (...) criticized. In response to criticisms, elaborations, and alternative comparators have been proposed. In this paper, I approach the search for workable comparators from the point of view that ethical reasoning about minimal risk involves analogical reasoning using comparators. In this regard, I develop two necessary conditions for an adequate minimal risk conception, which I use to assess three comparators. I conclude that the risks-of-routine-tests best fits the analogical reasoning operating in minimal risk assessments. (shrink)

Risk attitude is known to be a key determinant of various economic and financial choices. Behavioral studies that aim to evaluate the role of risk attitudes in contexts of this type, therefore, require tools for measuring individual risk tolerance. Recent developments in decision theory provide such tools. However, the methods available can be time consuming. As a result, some practitioners might have an incentive to prefer “fast and frugal” methods to clean but more costly methods. In this article, we focus (...) on a tractable procedure initially proposed by Holt and Laury (2002) to elicit risk attitude. We generalize this method to measure utility and risk aversion as follows. First, we allow measurement of probabilistic risk attitude through violations of expected utility due to probability weighting. Second, we use the outcome scale rather than the probability scale in the menu of choices. Third, we compare sure payoffs with lotteries instead of comparing non-degenerate lotteries.

In the case of Re M, summarised in the paper by Julian Sheather, Justice Baker faced the difficult task of weighing up objectively whether or not it was in Mâs best interests to withdraw artificial feeding and to let her die.1 The judge concluded that M was ârecognisably aliveâ, and that the advantages of continued life outweighed the disadvantages. He compared her minimally conscious state favourably to that of a persistent vegetative state .2 It was clear that artificial feeding would (...) have been withdrawn if she had been in a PVS , but because she was in fact minimally conscious, the judge decided that treatment must continue. But does it make sense to treat MCS differently from PVS in this way? Is it better to be minimally conscious than unconscious? Similar questions have been raised before.3 In 2006, scientists reported results of sophisticated neuroimaging studies which suggested that some patients in persistent vegetative state , long thought to be unaware, had evidence of minimal consciousness.4 The question then was on the moral significance of this level of consciousness, and whether the presence of such evidence meant that treatment such as artificial nutrition must be continued.5 ,6There are several potential reasons why the presence of minimal consciousness might warrant continuing life-sustaining treatment. The first is that patients in minimally conscious state might have a better prognosis than those who are in PVS. There are relatively few studies …. (shrink)

We extend our general approach to characterizing information to multi-agent systems. In particular, we provide a formal description of an agent''s knowledge containing exactly the information conveyed by some (honest) formula . Only knowing is important for dynamic agent systems in two ways. First of all, one wants to compare different states of knowledge of an agent and, secondly, for agent a''s decisions, it may be relevant that (he knows that) agent b does not know more than . There are (...) three ways to study the question whether a formula can be interpreted as minimal information. The first method is semantic and inspects minimal models for (with respect to some information order on states). The second one is syntactic and searches for stable expansions, minimal with respect to some language *. The third method is a deductive test, known as the disjunction property. We present a condition under which the three methods are equivalent. Then, we show how to construct the order by collecting layered orders. Focusing on the multi-agent case we identify languages * for various orders , and show how they yield different notions of honesty for different multi-modal systems. We then provide several tools for studying honesty types and illustrate their usefulness on a number of examples, for three modal systems of particular interest. Finally, we relate the different notions of minimal knowledge, and describe possible patterns of honesty for these systems. (shrink)

Non-beneficial paediatric research is vital to improving paediatric healthcare. Nevertheless, it is also ethically controversial. By definition, subjects of such studies are unable to give consent and they are exposed to risks only for the benefit of others, without obtaining any clinical benefits which could compensate those risks. This raises ethical concern that children participating in non-beneficial research are treated instrumentally; that they are reduced to mere instruments for the benefit of science and society. But this would make the research (...) incompatible with the widely endorsed principle of the primacy of the human subject, which stipulates that the interests of the participating individual should prevail over the interests of science and society. This paper deals with this conflict. It analyses solutions to this problem developed in the literature, and shows that they are unsuccessful. Finally, it offers a new idea of how to reconcile the conduct of non-beneficial paediatric research with the PP. The paper argues for a new formula of the PP, and shows that it implies a specific non-comparative definition of the minimal risk threshold. (shrink)

Some patients awaken from their coma but only show reflex motor activity. This condition of wakeful (eyes open) unawareness is called the vegetative state. In 2002, a new clinical entity coined ‘‘minimally conscious state’’ defined patients who show more than reflex responsiveness but remain unable to communicate their thoughts and feelings. Emergence from the minimally conscious state is defined by functional recovery of verbal or nonverbal communication.1 Our empirical medical definitions aim to propose clearcut borders separating disorders of consciousness such (...) as coma, vegetative state and minimally conscious state but clinical reality shows that these boundaries can often be fuzzy (fig 1). Recent clinical, electrophysiological and neuroimaging studies are shedding light on these challenging limits of consciousness encountered following severe acute brain damage. At the patient’s bedside, it is very challenging to differentiate reflex or automatic motor behaviour from movements indicating signs of consciousness, and hence some minimally conscious patients might be misdiagnosed as being vegetative. For some motor responses (eg, blinking to visual threat, brief fixation, normal flexion response to pain, etc) it remains unclear whether they truly are voluntary or willed because we lack convincing scientific evidence. We also lack consensus on how to practically assess some of these behavioural responses. For example, there is no agreement on what stimulus to employ in the assessment of visual pursuit movements— often one of the first clinical signs heralding the transition from the vegetative to the minimally conscious state. Vanhaudenhuyse and colleagues2 recently studied visual pursuit in 51 post-comatose patients comparing eye tracking of a moving object, person or mirror. It was shown that more.. (shrink)

Interactions between humans and bots are increasingly common online, prompting some legislators to pass laws that require bots to disclose their identity. The Turing test is a classic thought experiment testing humans’ ability to distinguish a bot impostor from a real human from exchanging text messages. In the current study, we propose a minimal Turing test that avoids natural language, thus allowing us to study the foundations of human communication. In particular, we investigate the relative roles of conventions and (...) reciprocal interaction in determining successful communication. Participants in our task could communicate only by moving an abstract shape in a 2D space. We asked participants to categorize their online social interaction as being with a human partner or a bot impostor. The main hypotheses were that access to the interaction history of a pair would make a bot impostor more deceptive and interrupt the formation of novel conventions between the human participants. Copying their previous interactions prevents humans from successfully communicating through repeating what already worked before. By comparing bots that imitate behavior from the same or a different dyad, we find that impostors are harder to detect when they copy the participants’ own partners, leading to less conventional interactions. We also show that reciprocity is beneficial for communicative success when the bot impostor prevents conventionality. We conclude that machine impostors can avoid detection and interrupt the formation of stable conventions by imitating past interactions, and that both reciprocity and conventionality are adaptive strategies under the right circumstances. Our results provide new insights into the emergence of communication and suggest that online bots mining personal information, for example, on social media, might become indistinguishable from humans more easily.

Hemiparetic stroke in adulthood often results in the grouped movement pattern of the upper extremity flexion synergy thought to arise from an increased reliance on cortico-reticulospinal pathways due to a loss of lateral corticospinal projections. It is well-established that the flexion synergy induces reaching constraints in individuals with adult-onset hemiplegia. The expression of the flexion synergy in individuals with brain injuries onset earlier in the lifespan is currently unknown. An early unilateral brain injury occurring prior to six months post full-term (...) may preserve corticospinal projections which can be used for independent joint control and thus minimizing the expression of the flexion synergy. This study uses kinematics of a ballistic reaching task to evaluate the expression of the flexion synergy in individuals with pediatric-onset hemiplegia (PH) ages six to seventeen years. Fifteen individuals with brain injuries before birth (n = 8) and around full-term (n = 7) and nine age-matched controls with no known neurological impairment completed a set of reaches in an admittance controlled robotic device. Descending drive, and the possible expression of the upper extremity flexion snergy, was modulated by increasing shoulder abduction loading. Individuals with early PH achieved lower peak velocities when reaching with the paretic arm compared to controls however no differences in reaching distance were found between groups. Relative maintenance in reaching seen in individuals with early brain injuries highlights minimal expression of the flexion synergy. We interpret this conservation of independent control of the paretic shoulder and elbow as the use of more direct corticospinal projections instead of indirect cortico-reticulospinal pathways used in individuals with adult-onset hemiplegia.

We develop a mathematical theory for comparative sorites, considered in terms of a system mapping pairs of stimuli into a binary response characteristic whose values supervene on stimulus pairs and are interpretable as the complementary relations 'are the same' and 'are not the same' (overall or in some respect). Comparative sorites is about hypothetical sequences of stimuli in which every two successive elements are mapped into the relation 'are the same', while the pair comprised of the first and the last (...) elements of the sequence is mapped into 'are not the same'. Although soritical sequences of this kind are logically possible, we argue that their existence is grounded in no empirical evidence and show that it is excluded by a certain psychophysical principle proposed for human comparative judgements in a context unrelated to soritical issues. We generalize this principle to encompass all conceivable situations for which comparative sorites can be formulated. (shrink)

We extend our general approach to characterizing information to multi-agent systems. In particular, we provide a formal description of an agent's knowledge containing exactly the information conveyed by some (honest) formula φ. Only knowing is important for dynamic agent systems in two ways. First of all, one wants to compare different states of knowledge of an agent and, secondly, for agent a's decisions, it may be relevant that (he knows that) agent b does not know more than φ. There are (...) three ways to study the question whether a formula φ can be interpreted as minimal information. The first method is semantic and inspects 'minimal' models for φ (with respect to some information order ≤ on states). The second one is syntactic and searches for stable expansions, minimal with respect to some language $\scr{L}^{\ast}$ . The third method is a deductive test, known as the disjunction property. We present a condition under which the three methods are equivalent. Then, we show how to construct the order ≤ by collecting 'layered orders'. Focusing on the multi-agent case we identify languages $\scr{L}^{\ast}$ for various orders ≤, and show how they yield different notions of honesty for different multi-modal systems. We then provide several tools for studying honesty types and illustrate their usefulness on a number of examples, for three modal systems of particular interest. Finally, we relate the different notions of minimal knowledge, and describe possible patterns of honesty for these systems. (shrink)

In vowel discrimination, commonly found discrimination patterns are directional asymmetries where discrimination is faster if differing vowels are presented in a certain sequence compared to the reversed sequence. Different models of speech sound processing try to account for these asymmetries based on either phonetic or phonological properties. In this study, we tested and compared two of those often-discussed models, namely the Featurally Underspecified Lexicon model and the Natural Referent Vowel framework. While most studies presented isolated vowels, we investigated a large (...) stimulus set of German vowels in a more naturalistic setting within minimal pairs. We conducted an mismatch negativity study in a passive and a reaction time study in an active oddball paradigm. In both data sets, we found directional asymmetries that can be explained by either phonological or phonetic theories. While behaviorally, the vowel discrimination was based on phonological properties, both tested models failed to explain the found neural patterns comprehensively. Therefore, we additionally examined the influence of a variety of articulatory, acoustical, and lexical factors but also the influence of factors beyond the well-known in depth via multiple regression analyses. The analyses revealed that the perceptual factor of perceived loudness has a greater impact than considered in the literature and should be taken stronger into consideration when analyzing preattentive natural vowel processing.

Applying Snyder and Feldman's 1984 consolidation‐transition model to moral judgement development has enabled further understanding of how moral judgement translates to moral functioning. In this study, 178 college students were identified as being in consolidated versus transitional phases of moral judgement development using Rest's Defining Issues Test (DIT). Participant moral functioning was inferred through an honest decision‐making index along with Attitudes Towards Human Rights Inventory (ATHRI) and Volunteer Functions Inventory (VFI) scores. Multivariate Analyses of Variance revealed that the consolidated group (...) was significantly more honest than the transitional group. No differences attributable to moral judgement phase were seen for ATHRI and VFI scores. Findings support the claim that consolidated phases improve the explanatory power of moral judgement for certain moral functional outcomes—particularly those involving ambiguity and minimal time for decision‐making.

The ``doctrinal paradox'' or ``discursive dilemma'' shows that propositionwise majority voting over the judgments held by multiple individuals on some interconnected propositions can lead to inconsistent collective judgments on these propositions. List and Pettit (2002) have proved that this paradox illustrates a more general impossibility theorem showing that there exists no aggregation procedure that generally produces consistent collective judgments and satisfies certain minimal conditions. Although the paradox and the theorem concern the aggregation of judgments rather than preferences, they invite (...) comparison with two established results on the aggregation of preferences: the Condorcet paradox and Arrow's impossibility theorem. We may ask whether the new impossibility theorem is a special case of Arrow's theorem, or whether there are interesting disanalogies between the two results. In this paper, we compare the two theorems, and show that they are not straightforward corollaries of each other. We further suggest that, while the framework of preference aggregation can be mapped into the framework of judgment aggregation, there exists no obvious reverse mapping. Finally, we address one particular minimal condition that is used in both theorems – an independence condition – and suggest that this condition points towards a unifying property underlying both impossibility results.
