We estimate that 208,000 deep brain stimulation (DBS) devices have been implanted to address neurological and neuropsychiatric disorders worldwide. DBS Think Tank presenters pooled data and determined that DBS expanded in its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. The DBS Think Tank was founded in 2012 providing a space where clinicians, engineers, researchers from industry and academia discuss current and emerging DBS technologies and logistical and ethical issues facing the field. (...) The emphasis is on cutting edge research and collaboration aimed to advance the DBS field. The Eighth Annual DBS Think Tank was held virtually on September 1 and 2, 2020 (Zoom Video Communications) due to restrictions related to the COVID-19 pandemic. The meeting focused on advances in: (1) optogenetics as a tool for comprehending neurobiology of diseases and on optogenetically-inspired DBS, (2) cutting edge of emerging DBS technologies, (3) ethical issues affecting DBS research and access to care, (4) neuromodulatory approaches for depression, (5) advancing novel hardware, software and imaging methodologies, (6) use of neurophysiological signals in adaptive neurostimulation, and (7) use of more advanced technologies to improve DBS clinical outcomes. There were 178 attendees who participated in a DBS Think Tank survey, which revealed the expansion of DBS into several indications such as obesity, post-traumatic stress disorder, addiction and Alzheimer’s disease. This proceedings summarizes the advances discussed at the Eighth Annual DBS Think Tank. (shrink)

Mental time travel is defined as projecting the self into the past and the future. Despite growing evidence of the similarities of remembering past and imagining future events, dominant theories conceive of these as distinct capacities. I propose that memory and imagination are fundamentally the same process – constructive episodic simulation – and demonstrate that the ‘simulation system’ meets the three criteria of a neurocognitive system. Irrespective of whether one is remembering or imagining, the simulation system: acts on the same (...) information, drawing on elements of experience ranging from fine-grained perceptual details to coarser-grained conceptual information and schemas about the world; is governed by the same rules of operation, including associative processes that facilitate construction of a schematic scaffold, the event representation itself, and the dynamic interplay between the two ; and is subserved by the same brain system. I also propose that by forming associations between schemas, the simulation system constructs multi-dimensional cognitive spaces, within which any given simulation is mapped by the hippocampus. Finally, I suggest that simulation is a general capacity that underpins other domains of cognition, such as the perception of ongoing experience. This proposal has some important implications for the construct of ‘MTT’, suggesting that ‘time’ and ‘travel’ may not be defining, or even essential, features. Rather, it is the ‘mental’ rendering of experience that is the most fundamental function of this domain-general simulation system enabling humans to re-experience the past, pre-experience the future, and also comprehend the complexities of the present.

Recognizing the links between childhood trauma and delinquency, many juvenile delinquency systems now emphasize trauma-informed care. This commentary examines established and emerging research on childhood trauma among American Indian and Alaska Native children and contrasts the development and implementation of “trauma-informed” approaches in state and tribal juvenile systems. It identifies three key innovations present in tribal models and calls for further research to identify best practices that work for Native children and tribal communities.

Karen Neander’s (1991a, b) Selected Effects (SE) theory of biological proper functions argues that the function of a trait is the action for which it was “caused” to be selected by natural selection. Her life’s work has already left a lasting impact, however SE theory has yet to be more properly formalized as a conceptual analysis of biological functions. Although other SE theories have sought to build upon Neander’s work (e.g., Garson, 2017), there remains an ambiguity in the theory’s use (...) of causal descriptors. For the success of her successors, delineating the function of causality for SE theory is of utmost importance. Here, I systematize Neander’s theory according to the different senses of causation inherent to it. I argue that structuring SE theory in terms of causal transitivity and intransitivity reveals that Neander’s analysis not only supersedes her detractors but likely exposes areas of vulnerability in others’ SE theory derivatives.

Reprint of the 1882 ed. published by Williams and Norgate, London.

Christian realism is undergoing a renaissance in both American Christianity and around the world. Caught between globalist liberalism, on the one hand, and pragmatic realism on the other, Christians are in search of international ethics, a standard and tradition in foreign policy, that takes the two great books of life, the Christian Scriptures and the world we live in, seriously. This book is an extended, edited collection that mines the tradition of Christian realism in international relations and finds in it (...) voices and mentors urgently fresh for a new age. With classic authors like Reinhold Niebuhr, Herbert Butterfield, Paul Ramsey, and Jean Bethke Elshtain, and contemporaries like Marc LiVecche, Rebecca Heinrichs, and others, this collection offers for the first time an organization, periodization, and collection of primary Christian realist sources for the initiate and the expert in foreign relations."--Provided by publisher.

Whether intentional suppression of an unpleasant or unwanted memory reduces the ability to recall that memory subsequently is a contested issue in contemporary memory research. Building on findings that similar processes are recruited when individuals remember the past and imagine the future, we measured the effects of thought suppression on memory for imagined future scenarios. Thought suppression reduced the ability to recall emotionally negative scenarios, but not those that were emotionally positive. This finding suggests that intentionally avoiding thoughts about emotionally (...) negative episodes may inhibit representations of those memories, progressively reducing their availability to recall.

Contrary to Vaesen's argument that humans are unique with respect to nine cognitive capacities essential for tool use, we suggest that although such cognitive processes contribute to variation in tool use, it does not follow that these capacities arenecessaryfor tool use, nor that tool use shaped cognition per se, given the available data in cognitive neuroscience and behavioral biology.

The title of this paper may, at first glance, somewhat surprise the casual reader. That the writings of a philosopher who was, by his own confession, an atheist should contain a trenchant critique of the theistic position is only to be expected; but the suggestion that any positive contribution to the philosophy of religion can be found in them may appear somewhat startling, and even paradoxical.

In lieu of an abstract, here is a brief excerpt of the content:242 HISTORY OF PHILOSOPHY his political and religious predispositions prodded him to demonstrate that the roots of modern science were in the Christian Middle Ages. Sarton's particular foibles are best understood by referring them to his pacifist commitments and the moralistic assumption that the values of science are transferable to other human endeavors. Categories such as inductivism, conventionalism and Popperianism are of little help in gaining historical understanding. For (...) this, they are in fact Platonic ideals which have little heuristic value. I would venture that a truly historical historiography of science would aid us in spotting errors in the past and help us in the future. My guess is that a good analysis would reveal a major source of trouble to have stemmed from preconceived notions which the history of science was meant to illustrate. Surely some of them have been philosophical in character, and even Baconian or conventionalist. But until recent times, most of these preconceptions have stemmed from religious, nationalistic, or personal motivations, or from scientists who wanted support for a particular concept. I agree with Agassi only in the suggestion that a parti pris was at the root of our troubles. Why, then, substitute a Popperian preconception for a conventionalist one? Why not, on the contrary, combat their distorting influence and reduce their impact? This is in fact what has happened in recent times. As the history of science has fallen into the hands of a gradually organized profession, the blatant motivations --of any type--which colored past historical writings have slowly receded. By a constant and critical confrontation of opposing views among specialists, the purpose for examining the history of science has slowly been transformed. The older external motivations have given way to an interest in the subject for its own sake and a gradual transformation has been in the making for the last few decades. As happens in other human endeavors, professionalization has already raised the standards in the discipline and there is every reason to think it will continue to do so in the future. We need not really be as pessimistic as Agassi, nor embrace his particular salvation. ROGEa HAm~ University o] Cali]ornia, Berkeley A MEDIEVAL ANALYSIS OF INFINITY IN THE COURSEof arguing that time must have had a beginning, St. Bonaventure (1221-74) put forward a demonstration which in some ways seems to anticipate Cantor's definition of infinity.1 Bonaventure pointed out that, if the world were infinitely old, then there would have been an infinite number of annual revolutions of the sun around the ecliptic. But during each such period there occur (roughly) twelve revolutions of the moon, i.e. lunar months or lunations. Thus there would be one infinity which was twelve times another--which, says Bonaventure, is impossible. This attempted proof might be formulated as the following For other adumbrationsof this definition,see I. Thomas,"A TwelfthCentury Paradoxof the Infinite,"Journal o] Symbolic Logic, XXIII (1958), 133-134, and W. & M. Kneale, The Development of Logic (Oxford,1962),p. 440. NOTES AND DISCUSSIONS 243 reductio ad absurdum, in which a revolution of the sun is specified as the period between successive vernal equinoxes. If there could be an infinite set of past lunations, then clearly it could be put in a one-to-one correspondence with a proper sub-set of itself--viz., with the set of past lunar months during which vernal equinoxes occurred. But this consequence is preposterous; no set could be so correlated with its own sub-set. Therefore the set of past lunar months cannot be infinite, and the world must have had a beginning. The passage, which is found in Bonaventure's commentary on the Sentences of Peter Lombard, reads as follows :2 Si mundus est aeternus, revolutiones solis in orbe suo sunt infmitae ; rursus, pro una revolutions solis necesse est fuisse duodecim ipsius lunae: ergo plus revoluta est luna quam sol; et sol infinities: ergo infinitorum ex ea parle, qua infinita sunt, est reperire excessum.

We argue that abduction does not work in isolation from other inference mechanisms and illustrate this through an inference scheme designed to evaluate multiple hypotheses. We use game theory to relate the abductive system to actions that produce new information. To enable evaluation of the implications of this approach we have implemented the procedures used to calculate the impact of new information in a computer model. Experiments with this model display a number of features of collective belief-revision leading to consensus-formation, (...) such as the influence of bias and prejudice. The scheme of inferential calculations invokes a Peircian concept of ‘belief’ as the propensity to choose a particular course of action. (shrink)

Syntactic and structural models specify relationships between their constituents but cannot show what outcomes their interaction would produce over time in the world. Simulation consists in iterating the states of a model, so as to produce behaviour over a period of simulated time. Iteration enables us to trace the implications and outcomes of inference rules and other assumptions implemented in the models that make up a theory. We apply this method to experiments which we treat as models of the particular (...) aspects of reality they are designed to investigate. Scientific experiments are constantly designed and re-designed in the context of implementation and use. They mediate between theoretical understanding and the practicalities of engaging with the empirical and social world. In order to model experiments we need to identify and represent features that all experiments have in common. We treat these features as parameters of a general model of experiment so that by varying these parameters different types of experiment can be modelled. (shrink)

Questions about the relationship between linguistic competence and expertise will be examined in the paper. Harry Collins and others distinguish between ubiquitous and esoteric expertise. Collins places considerable weight on the argument that ordinary linguistic competence and related phenomena exhibit a high degree of expertise. His position and ones which share close affinities are methodologically problematic. These difficulties matter because there is continued and systematic disagreement over appropriate methodologies for the empirical study of expertise. Against Collins, it will be argued (...) that the term ‘expertise’ should be reserved for expertise (esoteric experts) and exclude everyday performance (ubiquitous experts). Wittgensteinian ideas will be employed to maintain that it is mistaken and misleading to derive substantive conclusions about the epistemology of expertise from ordinary linguistic competence and vice versa. Significant attention will be devoted to the notion of following a rule with particular reference to the intelligibility of tacit rule following. A satisfactory theoretical approach to expertise should not involve making important claims about ordinary linguistic competence. (shrink)

Behaviorism and the philosophy of the act are widely believed to be inconsistent with one another. I argue that both are true, Fulfilling the requirements of scientific psychology and the phenomenology of mind, Respectively. The key to understanding their mutual consistency lies in the idea of parallelism and its corresponding requirement that all descriptive features of mental states be analyzed as properties, None as relations (to anything physical). So the intentional link itself must be a 'logical' and not a descriptive (...) connection. More broadly, It is required to free the act from its origins in the metaphysical notion of 'activity' and the substance ontology from which that motion derives. (shrink)

We consider the relation between past and future events from the perspective of the constructive episodic simulation hypothesis, which holds that episodic simulation of future events requires a memory system that allows the flexible recombination of details from past events into novel scenarios. We discuss recent neuroimaging and behavioral evidence that support this hypothesis in relation to the theater production metaphor.

According to the theory of dispositions here defended, to have a disposition is to have some (non-dispositional) property that enters into a law of a certain form. The theory does not have the crucial difficulty of the singular material implication account of dispositions, but at the same time avoids the unfortunate notion of 'reduction sentences'. It is further argued that no dispositional explanation is one of the covering-law type; but the theory shows how, for any dispositional explanation! To construct a (...) potential explanation of the covering-law type. The theory can also be applied fruitfully to human behavior, especially with respect to the issues of reasons and causes and of' rational' explanation. The success of the applicability of this theory of dispositions is further evidence of its adequacy. (shrink)

Servant leadership is increasingly gaining interest inside and outside academia. This article builds and extends current theorizing by describing the process that introduces compassionate love as a practical translation for the need to serve, which was positioned by Greenleaf as the core of servant leadership. This article takes a virtues perspective and shows how servant leadership may encourage a more meaningful and optimal human functioning with a strong sense of community to current-day organizations. In essence, we propose that a leader’s (...) propensity for compassionate love will encourage a virtuous attitude in terms of humility, gratitude, forgiveness and altruism. This virtuous attitude will give rise to servant leadership behavior in terms of empowerment, authenticity, stewardship and providing direction. (shrink)

First, a paradox, a problem in the problem of evil. I shall call it ‘the paradox of evil’. On the one hand it is of course widely held that the evils in the world present an insuperable difficulty for Judeo-Christian theism. Russell, to take a conspicuous example, challenges any orthodox believer to visit the bedside of a child terminally ill with cancer and yet to retain his faith without hypocrisy . No paradox here; just the familiar problem of evil.

An exciting introduction to the contribution which the later Wittgenstein made to the philosophy of religion. Although his writings on the subject have been few, Wittgenstein developed influential and controversial theories on both religion which emphasize the distinctive nature of religious discourse and how this nature can be misunderstood when viewed in direct competition with science. The contributors of this collection shed new light on the perennial debate between faith and reason. The result is a collection that is both informative (...) and stimulating. (shrink)

This collection of new essays put the debates on the mind-body problem into historical context.

We investigate how the just cause principle is applicable to contingency planning about armed interventions in civil wars that are somewhat likely to occur in the future. According to a 2005 peace agreement that formally ended a civil war between the Sudanese government in Khartoum and the Sudan People’s Liberation Army, a referendum on South Sudan independence is to be held no later than January 9, 2011. Close observers of Sudan warn that this promise of an independence referendum might not (...) be correctly fulfilled, and that a North-South civil war is somewhat likely to recur. Focusing on the case of Sudan, we discuss the following key question, from the temporal standpoint of August 2010, the month this paper was completed: How may the just cause principle be used prospectively to decide whether there would be a just cause for armed intervention in Sudan, if a renewed North-South civil war were to occur there during the years 2010–2014? To illuminate this question of application, we also discuss a question of theory. What is the just cause principle? A core thesis is that the deterrent threat of armed intervention is an essential tool for preventing such a civil war. By means of deterrent threats of limited forms of armed intervention—for instance, the deterrent threat of imposing no-fly zones—the balance of cost/benefit calculations by the Sudanese government about the prospect of civil war might be tipped in favor of acceptance of South Sudan independence. We recommend that responsible actors in the international community should plan contingently about such armed intervention in Sudan, with the goal of preventing a renewed North-South civil war there.
