We argue that heritability estimates cannot be used to make informed judgments about the populations from which they are drawn. Furthermore, predicting changes in heritability from population changes is likely impossible, and of limited value. We add that the attempt to separate human environments into cultural and non-cultural components does not advance our understanding of the environmental multiplier effect.

The Advaita Vedānta notion of ātman/Brahman presents a serious philosophical challenge to this school-namely, it demands that they explain how all (reality) can be undivided, unchanging, and pure consciousness, yet appear to be everything but nondual, unchanging, and pure consciousness. The Advaita answer is avidyā, ajāna (ignorance). This answer tells us that Brahman does not really change; it is only ignorance that makes it appear to change. This answer has engendered as many questions as it has resolved, and it is (...) possible that they can be boiled down to the following: how can vidyā and avidyā be simultaneous and coterminous? After reviewing the Advaita responses to the debates regarding avidyā, which arose within Advaita and between Advaitins and their opponents, a traditional Advaita path will be followed by offering an analogy to illuminate this quandary. The strength of this contemporary analogy, based on holography, lies in its ability to illuminate the nature of Brahman as being without parts, without duality, without change; yet holography presents us with images that appear to change and be with parts.

An integrated representation of large‐scale space, or cognitive map, colled PLAN, is presented that attempts to address a broader spectrum of issues than has been previously attempted in a single model. Rather than examining way‐finding as a process separate from the rest of cognition, one or the fundamental goals of this work is to examine how the wayfinding process is integrated into general cognition. One result of this approach is that the model is “heads‐up,” or scene‐based, because it takes advantage (...) of the properties of the human visual system and, particularly, the visual system's split into two pathways. The emphasis on the human location or “where” system is new to cognitive mapping and is port of an attempt to synthesize prototype theory, associative networks and location together in a connectionist system. Not all of PLAN is new, however. Many of its parts have analogues in one or another preexisting theory. What makes PLAN unique is integrating the various components into a coherent whole, and the capacity of this resulting system to speak to a wide range of constraints. Our approach emphasizes adaptiveness; thus, our focus on such issues as ease of use and efficiency of learning. The result is a model that has a stronger relationship both to the environment, and to the ways that humans interact with it, compared with previous models. The resulting model is examined in some detail and compared to other systems. (shrink)

ABOUT THE BOOK:Hermeneutics, Holography and Indian Idealism is a cross-cultural and interdisciplinary analysis of the notion of projection. Advaita Vedanta informs us that mind is projected `out-there` into the world during perception. Is this notion.

Amit's efforts to provide stronger theoretical and empirical support for Hebb's cell-assembly concept is admirable, but we have serious reservations about the perspective presented in the target article. For Hebb, the cell assembly was a building block; by contrast, the framework proposed here eschews the need to fit the assembly into a broader picture of its function.

In the first section of the article, we examine some recent criticisms of the connectionist enterprise: first, that connectionist models are fundamentally behaviorist in nature (and, therefore, non-cognitive), and second that connectionist models are fundamentally associationist in nature (and, therefore, cognitively weak). We argue that, for a limited class of connectionist models (feed-forward, pattern-associator models), the first criticism is unavoidable. With respect to the second criticism, we propose that connectionist modelsare fundamentally associationist but that this is appropriate for building models (...) of human cognition. However, we do accept the point that there are cognitive capacities for which any purely associative model cannot provide a satisfactory account. The implication that we draw from is this is not that associationist models and mechanisms should be scrapped, but rather that they should be enhanced.In the next section of the article, we identify a set of connectionist approaches which are characterized by “active symbols” — recurrent circuits which are the basis of knowledge representation. We claim that such approaches avoid criticisms of behaviorism and are, in principle, capable of supporting full cognition. In the final section of the article, we speculate at some length about what we believe would be the characteristics of a fully realized active symbol system. This includes both potential problems and possible solutions (for example, mechanisms needed to control activity in a complex recurrent network) as well as the promise of such systems (in particular, the emergence of knowledge structures which would constitute genuine internal models).

Rachlin's thought-provoking analysis could be strengthened by greater openness to evolutionary interpretation and the use of the directed attention concept as a component of self-control. His contribution to the understanding of prosocial behavior would also benefit from abandoning the traditional (and excessively restrictive) definition of altruism.

Abstract Daniel H. H. Ingalls referred to Gaudap?da's M?nd?kya K?rik?, a very early Advaita text, as ? ... the most puzzling perhaps, of all Sanskrit philosophical texts?. This article shows that some of the philosophical quandaries associated with this text are the result of inappropriately imposing a graphic and prose model of textuality upon a text composed in the k?rik? (memorial verse) genre and in an oral cultural context. Developing a model of textuality consistent with the literary genre and cultural (...) context, the article is not only able to resolve some of the philosophical problems associated with the text, but also raises the possibility that this inappropriate hermeneutical process has contributed to mislabelling Gaudap?da as an idealist.

Krishnachandra Bhattacharyya, one of the preeminent Indian philosophers of the 20th century, proposed that the absolute appears in three alternative forms - truth, freedom and value. Each of these forms are for Bhattacharyya absolute, ultimate, not penultimate. Each is different from the other, yet they cannot be said to be one or many. He contends that these absolutes are incompatible with each other and that an articulation of the relation between the three absolutes is not feasible. This paper will review (...) Bhattacharyya 's presentation of the absolute in its alternative forms and will place these abstractions within the context of three specific religious traditions that he sees illustrating his point. Then, using a model based upon holography, I will illuminate with 'concrete images' that which Bhattacharyya could deductively formulate but could not logically integrate. Holography, the process by which three-dimensional images are produced from an imageless film - a film in which each part can reproduce the whole - will be used as a heuristic device to illuminate the simultaneous and mutually interpenetrating existence of the absolute in three forms. This model will illumine how these three forms can be conceived of as not the same yet not other and how these forms can be incompatible as absolutes, but metaphysically inseparable. (shrink)

This paper articulates an infusion model of ethics education for engineering students by illuminating the value of a religious studies course on yoga. This model is distinguished from four other possible approaches that have traditionally been used to prepare engineering students to face the challenges of the work place. The article is not claiming that this approach should be used to the exclusion of the other approaches, but rather that it adds strength to the other approaches. Specifically, the article claims (...) that the infusion model provides an opportunity for students to reflect upon the foundational ethical positions emanating from the world’s religions and thereby provides them with a vista from which they can not only ask what professional ethical code applies in a given situation, but also ponder the nature of character needed to follow that ethical code.

Pulvermüller's work in extending Hebb's theory into the realm of language is exciting. However, we feel that what he characterizes as a single cell assembly is actually a set of cooperating cell assemblies that form parts of larger cognitive structures. These larger structures account more easily for a variety of phenomena, including the psycholinguistic.

Page's target article makes a good case for the strength of localist models. This can be characterized as an issue of where new information is integrated with respect to existing knowledge structures. We extend the analysis by discussing the dimension of when this integration takes place, the implications, and how they guide us in the creation of cognitive models.

Perceptual learning mechanisms derived from Hebb's theory of cell assemblies can generate prototypic representations capable of extending the representational power of TEC (Theory of Event Coding) event codes. The extended capability includes categorization that accommodates “family resemblances” and problem solving that uses cognitive maps.

We propose a way in which Barsalou could strengthen his position and at the same time make a considerable dent in the category/abstraction problem (that he suggests remains unsolved). There exists a class of connectionist models that solves this problem parsimoniously and provides a mechanistic underpinning for the promising high-level architecture he proposes.

Although Glenberg 's theory benefits from the incorporation of a suppression concept, a more differentiated view of suppression would be even more effective. We propose such a concept, showing how it accounts for phenomena that Glenberg describes and also for phenomena that he ignores.

How might epistemology build upon its past and present, so as to be better in the future? Epistemology Futures takes bold steps towards answering that question. What methods will best serve epistemology? Which phenomena and concepts deserve more attention from it? Are there approaches and assumptions that have impeded its progress until now? This volume contains provocative essays by prominent epistemologists, presenting many new ideas for possible improvements in how to do epistemology. Contributors: Paul M. Churchland, Catherine Z.

Lewis et al. (2011) attempted to restore the reputation of Samuel George Morton, a 19th century physician who reported on the skull sizes of different folk-races. Whereas Gould (1978) claimed that Morton’s conclusions were invalid because they reflected unconscious bias, Lewis et al. alleged that Morton’s findings were, in fact, supported, and Gould’s analysis biased. We take strong exception to Lewis et al.’s thesis that Morton was “right.” We maintain that Gould was right to reject Morton’s analysis as inappropriate and (...) misleading, but wrong to believe that a more appropriate analysis was available. Lewis et al. fail to recognize that there is, given the dataset available, no appropriate way to answer any of the plausibly interesting questions about the “populations” in question (which in many cases are not populations in any biologically meaningful sense). We challenge the premise shared by both Gould and Lewis et al. that Morton’s confused data can be used to draw any meaningful conclusions. This, we argue, reveals the importance of properly focusing on the questions asked, rather than more narrowly on the data gathered. (shrink)

Rationale Treatment guidelines recommend a more conservative surgical approach than mastectomy for early stage breast cancer and a stronger emphasis on adjuvant therapy. Registry data at South Australian teaching hospitals have been used to monitor survivals and treatment in relation to these guidelines.Aims and objectives To use registry data to: (1) investigate trends in survival and treatment; and (2) compare treatment with guidelines.Methods Registry data from three teaching hospitals were used to analyse trends in primary courses of treatment of breast (...) cancers during 1977–2003 (n = 4671), using univariate analyses and multiple logistic regression. Disease-specific survivals were analysed using Kaplan–Meier product limit estimates and multivariable Cox proportional hazards regression.Results The 5-year survival was 79.9%, but with a secular increase, reaching 83.6% in 1997–2003. The relative risk of death (95% confidence limits) was 0.74 (0.62, 0.88) for 1997–2003, compared with previous diagnoses, after adjusting for tumour node metastasis stage, grade, age and place of residence. Treatment changes included an increase in conservative surgery (as opposed to mastectomy) from 51.7% in 1977–1990 to 76.8% in 1997–2003 for stage I (P < 0.001) and from 31.1% to 52.2% across these periods for stage II (P < 0.001). Adjuvant radiotherapy also became more common (P < 0.001), with 20.6% of patients receiving this treatment in 1977–1990 compared with 60.7% in 1997–2003. Radiotherapy generally was more prevalent when conservative surgery was provided, although also relatively common in mastectomy patients when tumour diameters exceeded 50 mm or when there were four or more involved nodes. The proportion of patients receiving chemotherapy increased (P < 0.001), from 19.6% in 1977–1990 to 36.9% in 1997–2003, and the proportion having hormone therapy also increased (P < 0.001), from 34.3% to 59.4% between these periods.Conclusions Survivals appear to be increasing and treatment trends are broadly consistent with guideline directions, and the earlier research on which these recommendations were based.

_A moving meditation on recent geopolitical crises, viewed through the lens of ancient and modern tragedy__ “Spare, elegant and poignant.... If there is a single contemporary book that should be pressed into the hands of those who decide issues of war and peace, this is it.”—John Gray, _New Statesman_ “It is tragic that Robert D. Kaplan’s luminous _The Tragic Mind_ is so urgently needed.”—George F. Will_ Some books emerge from a lifetime of hard-won knowledge. Robert D. Kaplan has (...) learned, from a career spent reporting on wars, revolutions, and international politics in Europe, the Middle East, and East Asia, that the essence of geopolitics is tragedy. In _The Tragic Mind_, he employs the works of ancient Greek dramatists, Shakespeare, German philosophers, and the modern classics to explore the central subjects of international politics: order, disorder, rebellion, ambition, loyalty to family and state, violence, and the mistakes of power. The great dilemmas of international politics, he argues, are not posed by good versus evil—a clear and easy choice—but by contests of good versus good, where the choices are often searing, incompatible, and fraught with consequences. A deeply learned and deeply felt meditation on the importance of lived experience in conducting international relations, this is a book for everyone who wants a profound understanding of the tragic politics of our time.

Food is a challenging subject. There is little consensus about how and what we should produce and consume. It is not even clear what food is or whether people have similar experiences of it. On one hand, food is recognized as a basic need, if not a basic right. On the other hand, it is hard to generalize about it given the wide range of practices and cuisines, and the even wider range of tastes. This book is an introduction to (...) the philosophical dimensions of food. David M. Kaplan examines the nature and meaning of food, how we experience it, the social role it plays, its moral and political dimensions, and how we judge it to be delicious or awful. He shows how the different branches of philosophy contribute to a broader understanding of food: what food is (metaphysics), how we experience food (epistemology), what taste in food is (aesthetics), how we should make and eat food (ethics), how governments should regulate food (political philosophy), and why food matters to us (existentialism). Kaplan embarks on a series of philosophical investigations, considering topics such as culinary identity and authenticity, tasting and food criticism, appetite and disgust, meat eating and techno-foods, and consumerism and conformity. He emphasizes how different narratives help us navigate the complex world of food -- yet we all have responsibilities to ourselves, to others, and to animals. An original treatment of a timely subject, Food Philosophy is suitable for undergraduates while making a significant contribution to scholarly debates. (shrink)

A comprehensive reassessment of the concept of mimesis in the history of ancient Greek aesthetics and philosophy of art, with particular attention to Plato, Aristotle, Hellenistic philosophy, and neoplatonism. There is also a wide-ranging review of arguments pro and contra the idea of artistic mimesis from the Renaissance to modern literar theory. The book challenges standard accounts in numerous respects and builds a new dialectical model with which to make sense of the entire history of mimeticist thinking in aesthetics.

Since the late 1970s, theologians have been attempting to integrate mimetic theory into different fields of theology, yet a distrust of mimetic theory persists in some theological camps. In" Rene Girard, Unlikely Apologist: Mimetic Theory and Fundamental Theology," Grant Kaplan brings mimetic theory into conversation with theology both to elucidate the relevance of mimetic theory for the discipline of fundamental theology and to understand the work of Rene Girard within a theological framework. Rather than focus on Christology or atonement (...) theory as the locus of interaction between Girard and theology, Kaplan centers his discussion on the apologetic quality of mimetic theory and the impact of mimetic theory on fundamental theology, the subdiscipline that grew to replace apologetics. His book explores the relation between Girard and fundamental theology in several keys. In one, it understands mimetic theory as a heuristic device that allows theological narratives and positions to become more intelligible and, by so doing, makes theology more persuasive. In another key, Kaplan shows how mimetic theory, when placed in dialogue with particular theologians, can advance theological discussion in areas where mimetic theory has seldom been invoked. On this level the book performs a dialogue with theology that both revisits earlier theological efforts and also demonstrates how mimetic theory brings valuable dimensions to questions of fundamental theology. "Grant Kaplan's" Rene Girard, Unlikely Apologist: Mimetic Theory and Fundamental Theology" is an accessible and original work advancing the discussion of Girard and theology. Kaplan claims mimetic theory for Catholic theology and shows how it can strengthen Catholic theology by providing a powerful apologetic. Immensely helpful, too, is his situating of Girard's work alongside formative theologians and other thinkers."

Aboutness has been studied from any number of angles. Brentano made it the defining feature of the mental. Phenomenologists try to pin down the aboutness-features of particular mental states. Materialists sometimes claim to have grounded aboutness in natural regularities. Attempts have even been made, in library science and information theory, to operationalize the notion. But it has played no real role in philosophical semantics. This is surprising; sentences have aboutness-properties if anything does. Aboutness is the first book to examine through (...) a philosophical lens the role of subject matter in meaning. A long-standing tradition sees meaning as truth-conditions, to be specified by listing the scenarios in which a sentence is true. Nothing is said about the principle of selection--about what in a scenario gets it onto the list. Subject matter is the missing link here. A sentence is true because of how matters stand where its subject matter is concerned. Stephen Yablo maintains that this is not just a feature of subject matter, but its essence. One indicates what a sentence is about by mapping out logical space according to its changing ways of being true or false. The notion of content that results--directed content--is brought to bear on a range of philosophical topics, including ontology, verisimilitude, knowledge, loose talk, assertive content, and philosophical methodology. Written by one of today's leading philosophers, Aboutness represents a major advance in semantics and the philosophy of language. (shrink)
