This book takes readers on a fascinating journey to the very heart of Tantra: its key teachings, foundational lineages, and transformative practices. Since the West's discovery of Tantra 100 years ago, there has been considerable fascination, speculation, and more than a little misinformation about this spiritual movement. Now, for the first time in the English language, Tantra Illuminated presents an accessible introduction to this sacred tradition that began 1,500 years ago, in the far north of India. The book uses translations (...) from primary Sanskrit sources, offers a profound look at spiritual practice, and reveals Tantra's rich history and powerful teachings. (shrink)

Originally published in 1972, Should Trees Have Standing? was a rallying point for the then burgeoning environmental movement, launching a worldwide debate on the basic nature of legal rights that reached the U.S. Supreme Court. Now, in the 35th anniversary edition of this remarkably influential book, Christopher D. Stone updates his original thesis and explores the impact his ideas have had on the courts, the academy, and society as a whole. At the heart of the book is an eminently (...) sensible, legally sound, and compelling argument that the environment should be granted legal rights. For the new edition, Stone explores a variety of recent cases and current events--and related topics such as climate change and protecting the oceans--providing a thoughtful survey of the past and an insightful glimpse at the future of the environmental movement. This enduring work continues to serve as the definitive statement as to why trees, oceans, animals, and the environment as a whole should be bestowed with legal rights, so that the voiceless elements in nature are protected for future generations.

Between Sickness and Health is about illness rather than disease, and recovery rather than cure. The book argues that illness is an experience, represented by the feeling that 'I am not myself'. From the book's phenomenological point of view, feelings of illness cannot be 'unreal' or 'fake', whatever their biological basis, nor need they be categorised as 'physical', 'psychosomatic' or 'psychiatric'. The book challenges the disease-centred ethos of medicine and medical education. It demonstrates that a clearer conception of illness, as (...) distinct from disease, is therapeutic. The feeling that 'I am once again myself' can return, in some degree, whatever state the body is in. Resilience becomes more available when it is seen as a set of personal skills that can be developed, rather than as an inborn trait. Possibilities of wellness are enhanced by recognising that medical and other therapies can either support or impede recovery, as can human relationships and the socio-political environment. The book's many clinical examples are drawn from the author's broad experience as a neurologist, rehabilitation physician and systemic family therapist. Between Sickness and Health will be useful for students, practitioners and academics, and also for anyone who has been or might one day be ill. (shrink)

We have only limited awareness of the system by which we control our actions and this limited awareness does not seem to be concerned with the control of action. Awareness of choosing one action rather than another comes after the choice has been made, while awareness of initiating an action occurs before the movement has begun. These temporal differences bind together in consciousness the intention to act and the consequences of the action. This creates our sense of agency. Activity in (...) the anterior cingulate cortex and medial prefrontal cortex is associated with awareness of our own actions and also occurs when we think about the actions of others. I propose that the mechanism underlying awareness of how our own intentions lead to actions can also be used to represent the intentions that underlie the actions of others. This common system enables us to communicate mental states and thereby share our experiences. (shrink)

The Quaestiones super Physica Aristotelis traditionally attributed to Iohannes Canonicus survive in over 35 manuscripts and at least 8 printings from 1475 to 1520. Yet historians have disagreed about the century, the place of origin, the name and the institutional position of the author. This brief paper combines old and new evidence proving that the text was authored by an Augustinian Canon Regular of the Cathedral of Tortosa named Francesc Marbres, a Catalan from Barcelona, while he was Master of Arts (...) at the University of Toulouse around 1330.

This paper presents the first use of a computational model of natural logic—a system of logical inference which operates over natural language—for textual inference. Most current approaches to the PAS- CAL RTE textual inference task achieve robustness by sacrificing semantic precision; while broadly effective, they are easily confounded by ubiquitous inferences involving monotonicity. At the other extreme, systems which rely on first-order logic and theorem proving are precise, but excessively brittle. This work aims at a middle way. Our system finds (...) a low-cost edit sequence which transforms the premise into the hypothesis; learns to classify entailment relations across atomic edits; and composes atomic entailments into a top-level entailment judgment. We provide the first reported results for any system on the FraCaS test suite. We also evaluate on RTE3 data, and show that hybridizing an existing RTE system with our natural logic system yields significant performance gains. (shrink)

Christopher Frith is a research professor at the Functional Imaging Laboratory of the Wellcome Department of Imaging Neuroscience at University College, London. He explores, experimentally, using the techniques of functional brain imaging, the relationship between human consciousness and the brain. His research focuses on questions pertaining to perception, attention, control of action, free will, and awareness of our own mental states and those of others. As the following discussion makes clear, Frith investigates brain systems involved in the choice of (...) one action over another and in the understanding of other people. Such investigations are aimed at understanding brain basis of autism and schizophrenia. In his widely cited study of schizophrenia, The Cognitive Neuropsychology of Schizophrenia , Frith argues that many of the positive symptoms of schizophrenia, such as delusions of control, auditory hallucinations, and thought insertion, involve problems of self-monitoring. Patients, in effect, lose track of their own intentions and mistakenly attribute agency for their own actions to someone else. Frith employs models of motor control, involving comparator mechanisms and efference copy, not only to explain delusions that involve movement, but also to develop a neurocognitive explanation of delusional cognition.

I wish to present a codi cation of syntactic approaches to dealing with ergative languages and argue for the correctness of one particular approach, which I will call the Inverse Grammatical Relations hypothesis.1 I presume familiarity with the term `ergativity', but, brie y, many languages have ergative case marking, such as Burushaski in (1), in contrast to the accusative case marking of Latin in (2). More generally, if we follow Dixon (1979) and use A to mark the agent-like argument of (...) a transitive verb, O to mark the patient-like argument of a transitive verb, and S to mark the single argument of an intransitive verb, then we can call ergative any subsystem of a language that groups S and O in contrast to A, as shown in (3).

Increasingly, voices in the growing neurodiversity movement are alleging that individuals who are neurologically divergent, such as those with conditions related to bipolar disorder, autism, schizophrenia, and depression, must struggle for their civil rights. This movement therefore raises questions of interest to scholars in the humanities and social sciences, as well as to concerned members of the general public. These questions have to do with such matters as the accessibility of knowledge about mental health; autonomy and community within the realm (...) of the mentally ill; and accommodation in civil society and its institutions. The contributors to Ethics and Neurodiversity explore these questions, and the traditional philosophical questions related to them. The authors pay special attention to the need to examine the policies and practices of institutions, such as higher education, social support, and healthcare. (shrink)

Throughout, there are many case histories to illustrate the text.

We propose a model of natural language inference which identifies valid inferences by their lexical and syntactic features, without full semantic interpretation. We extend past work in natural logic, which has focused on semantic containment and monotonicity, by incorporating both semantic exclusion and implicativity. Our model decomposes an inference problem into a sequence of atomic edits linking premise to hypothesis; predicts a lexical semantic relation for each edit; propagates these relations upward through a semantic composition tree according to properties of (...) intermediate nodes; and joins the resulting semantic relations across the edit sequence. A computational implementation of the model achieves 70% accuracy and 89% precision on the FraCaS test suite. Moreover, including this model as a component in an existing system yields significant performance gains on the Recognizing Textual Entailment challenge. (shrink)

Environmental ethics has reached a certain level of maturity; further significant advances require reexamining its status within the larger realm of moral philosophy. It could aim to extend to nonhumans one of the familiar sets of principles subject to appropriate modifications; or it could seek to break away and put forward its own paradigm or paradigms. Selecting the proper course requires as the most immediate mission exploring the formal requirements of an ethical system. In general, are there constraints against bringing (...) our moral relations with different sorts of things under different mIes of govemance? In particular, how much independence can an environmental ethic (or ethics) aim to have? (shrink)

This paper proposes a new architecture for textual inference in which finding a good alignment is separated from evaluating entailment. Current approaches to semantic inference in question answering and textual entailment have approximated the entailment problem as that of computing the best alignment of the hypothesis to the text, using a locally decomposable matching score. While this formulation is adequate for representing local (word-level) phenomena such as synonymy, it is incapable of representing global interactions, such as that between verb negation (...) and the addition/removal of qualifiers, which are often critical for determining entailment. We propose a pipelined approach where alignment is followed by a classification step, in which we extract features representing high-level characteristics of the entailment problem, and give the resulting feature vector to a statistical classifier trained on development data.

The systematic examination of the relationship between brain and behavior is generally considered to have begun in 1861 with Broca's description of a patient with a specific language deficit associated with a circumscribed lesion of the left frontal cortex. This observation was taken to show that there was a specific region in the brain concerned with language which was relatively independent of other regions concerned with other abilities. In the next decade a number of other patients were described with various (...) circumscribed deficits. Wernicke described aphasic patients who, in contrast to Broca's patients, were better at speech production than they were in understanding speech. Harlow described the case of Phineas Gage, who showed little sign of loss in his intellectual abilities but suffered a disastrous change in personality after bilateral damage to his frontal cortex. The aim of many of these early neuropsychologists was to associate particular psychological functions with specific brain regions by detailed study of neurological cases. (shrink)

This paper distinguishes between epistemic and metaphysical problems of arbitrariness for vagueness. It argues that epistemicism can resolve the epistemic problem of arbitrariness but not the metaphysical one.

We propose an approach to natural language inference based on a model of natural logic, which identifies valid inferences by their lexical and syntactic features, without full semantic interpretation. We greatly extend past work in natural logic, which has focused solely on semantic containment and monotonicity, to incorporate both semantic exclusion and implicativity. Our system decomposes an inference problem into a sequence of atomic edits linking premise to hypothesis; predicts a lexical entailment relation for each edit using a statistical classifier; (...) propagates these relations upward through a syntax tree according to semantic properties of intermediate nodes; and composes the resulting entailment relations across the edit sequence. We evaluate our system on the FraCaS test suite, and achieve a 27% reduction in error from previous work. We also show that hybridizing an existing RTE system with our natural logic system yields significant gains on the RTE3 test suite. (shrink)

We present a system for deciding whether a given sentence can be inferred from text. Each sentence is represented as a directed graph (extracted from a dependency parser) in which the nodes represent words or phrases, and the links represent syntactic and semantic relationships. We develop a learned graph matching model to approximate entailment by the amount of the sentence’s semantic content which is contained in the text. We present results on the Recognizing Textual Entailment dataset (Dagan et al., 2005), (...) and show that our approach outperforms Bag- Of-Words and TF-IDF models. (shrink)

Mechanisms of selective attention are vital for coherent perception and action. Recent advances in cognitive neuroscience have yielded key insights into the relationship between neural mechanisms of attention and eye movements, and the role of frontal and parietal brain regions as sources of attentional control. Here we explore the growing contribution of reversible neurodisruption techniques, including transcranial magnetic stimulation and microelectrode stimulation, to the cognitive neuroscience of spatial attention. These approaches permit unique causal inferences concerning the relationship between neural processes (...) and behaviour, and have revealed fundamental mechanisms of attention in the human and animal brain. We conclude by suggesting that further advances in the neuroscience of attention will be facilitated by the combination of neurodisruption techniques with established neuroimaging methods. (shrink)

MutL family proteins contain an N‐terminal ATPase domain (NTD), an unstructured interdomain linker, and a C‐terminal domain (CTD), which mediates constitutive dimerization between subunits and often contains an endonuclease active site. Most MutL homologs direct strand‐specific DNA mismatch repair by cleaving the error‐containing daughter DNA strand. The strand cleavage reaction is poorly understood; however, the structure of the endonuclease active site is consistent with a two‐ or three‐metal ion cleavage mechanism. A motif required for this endonuclease activity is present in (...) the unstructured linker of Mlh1 and is conserved in all eukaryotic Mlh1 proteins, except those from metamonads, which also lack the almost absolutely conserved Mlh1 C‐terminal phenylalanine‐glutamate‐arginine‐cysteine (FERC) sequence. We hypothesize that the cysteine in the FERC sequence is autoinhibitory, as it sequesters the active site. We further hypothesize that the evolutionary co‐occurrence of the conserved linker motif with the FERC sequence indicates a functional interaction, possibly by linker motif‐mediated displacement of the inhibitory cysteine. This role is consistent with available data for interactions between the linker motif with DNA and the CTDs in the vicinity of the active site. (shrink)

This article examines the author, date, place, sources and reception of the Quaestiones libri Physicorum by the Catalan Augustinian Canon Francesc Marbres, usually attributed to “John the Canon.” The Quaestiones are perhaps the most influential philosophical work by an Augustinian Canon in the university era. From Barcelona, Marbres became a Canon of Tortosa Cathedral, a Master of Arts at Toulouse, and an advanced student in theology, probably at Paris, where he died. In his Quaestiones, compiled around 1330, his main sources (...) were works, primarily Sentential commentaries, by Franciscan theologians active at Paris from John Duns Scotus to Gerald Odonis. The Quaestiones survive in only two fourteenth- century manuscripts, described here, but at least 37 manuscripts and eight printings from the fifteenth and sixteenth centuries attest to its later reception, which is traced down to the present day. Appended to the article is an annotated question- and citation-list. In part II of this... (shrink)

This is Part II of a two-part study on the questions on Aristotles’ Physics by Francesc Marbres, the artist commonly known as “John the Canon.” Although written around 1330, only two fourteenth-century manuscripts preserve the work, but it became so popular around 1450 that dozens of fifteenth-century manuscripts containing the work survive and it was printed eight times from 1475 to 1520. Here the manuscripts and early prints are described, and then an attempt is made to trace the tradition of (...) the text using structural differences, the colophons and variant readings in the question-titles and small passages. These three sets of data turn out to be insufficient for constructing a stemma; instead they provide evidence of extensive contamination, suggesting that many scribes and printers employed more than one witness. This conclusion reinforces what we learn from marginalia and from information about the Oxford curriculum: the questions on the Physics by the mysterious “John the Canon” played an active rol...

In this book, Christopher D. Rodkey asks how the brain worships and responds by engaging ideas from neurological science, philosophy, ritual theory, and religious education. The Synaptic Gospel will prove to be a useful theoretical tool for pastors, religious educators, youth ministers, church music professionals, and seminary students.
