Background: Meditation is gaining recognition as a tool to impact health and well-being. Samyama is an 8-day intensive residential meditation experience conducted by Isha Foundation requiring several months of extensive preparation and vegan diet. The health effects of Samyama have not been previously studied. The objective was to assess physical and emotional well-being before and after Samyama participation by evaluating psychological surveys and objective health biomarkers.Methods: This was an observational study of 632 adults before and after the Isha Samyama retreat. (...) All participants were invited to complete surveys. Controls included household significant others. Surveys were completed at baseline, just before Samyama, immediately after Samyama, and 3 months later to assess anxiety, depression, mindfulness, joy, vitality, and resilience through validated psychometric scales. Voluntary blood sampling for biomarker analysis was done to assess hemoglobin, HbA1c, lipid profile, and C-reactive protein. Primary outcomes were changes in psychometric scores, body weight, and blood biomarkers.Results: Depression and anxiety scores decreased from T1 to T3, with the effect most pronounced in participants with baseline depression or anxiety. Scores at T4 remained below baseline for those with pre-existing depression or anxiety. Vitality, resilience, joy, and mindfulness increased from T1 to T3. Body weight decreased by 3% from T1 to T3. Triglycerides were lower from T2 to T3. Participants had lower HbA1c and HDL at T2, and lower CRP at all timepoints compared with controls.Conclusions: Participation in the Isha Samyama program led to multiple benefits. The 2-month preparation reduced anxiety, and participants maintained lower anxiety levels at 3 months post-retreat. Physical health improved over the course of the program as evidenced by weight loss and improved HbA1C and lipid profile. Practices associated with the Samyama preparation phase and the retreat may serve as an effective way to improve physical and mental health. Future studies may examine their use as an alternative therapy in patients with depression and/or anxiety.Clinical Trial Registration:www.ClinicalTrials.gov, Identifier: 1801728792.

Sometimes, there are reasons for which we believe, intend, resent, decide, and so on: these reasons are the “bases” of the latter, and the explanatory relation between these bases and the latter is what I will call “the basing relation.” What kind of explanatory relation is this? Dispositionalists claim that the basing relation consists in the agent’s manifesting a disposition to respond to those bases by having the belief, intention, resentment, and so on, in question. Representationalists claim that the basing (...) relation consists in the agent’s representing the bases as justifying the belief, intention, resentment, and so on, in question. This article shows that an adequate account of the basing relation requires a particular refinement and combination of these two views. On the hybrid account defended here, the basing relation involves a disposition exercise that is individuated by the agent’s object-involving de se representation of that very exercise as justifying.

What is the epistemological value of perceptual experience? In his recently influential paper, “The Skeptic and the Dogmatist”1, James Pryor develops a seemingly plausible answer to this question. Pryor’s answer comprises the following three theses: (F) “Our perceptual justification for beliefs about our surroundings is always defeasible – there are always possible improvements in our epistemic state which would no longer support those beliefs.” (517) (PK) “This justification that you get merely by having an experience as of p can sometimes (...) suffice to give you knowledge that p is the case.” (520) (D) “When it perceptually seems to you as if p is the case, you have a kind of justification for believing p that does not presuppose or rest on your justification for anything else, which could be cited in argument (even an ampliative argument) for p. To have this justification for believing p, you need only have an experience that represents p as being the case. No further awareness or reflection or background beliefs are required.” (519) Let’s use the phrase “fallibilist dogmatism” to refer to the conjunction of (F), (PK), and (D).2 Pryor does not argue for either (F) or (PK) in his paper; he simply shares the widespread and plausible assumption that (F) and (PK) are both true. But the conjunction of (F) and (PK) implies that we can have knowledge on the basis of defeasible justification. And this view leads to paradox. Consider the following individually plausible but jointly incompatible statements. (shrink)

Epistemology is one of the oldest, yet still one of the most active, areas of philosophical research today. There currently exists many annotated tomes of primary sources, and a handful of single-authored introductions to the field, but there is no book that captures epistemology’s dynamic growth and lively debates for a student audience. In this volume, eight leading philosophers debate four topics central to recent research in epistemology: The A Priori: C. S. I. Jenkins and Michael Devitt The A Posteriori: (...) Richard Fumerton and Nicholas Silins The Regress of Justification: Declan Smithies and Peter Klein Skepticism: Anthony Brueckner and Ernest Sosa Ram Neta’s introduction to the volume, descriptions of each chapter, annotated bibliographies for each controversy, and supplemental guide to further controversies in epistemology help provide clearer and richer views of active controversies for all readers.

In the last decade, reading research has seen a paradigmatic shift. A new wave of computational models of orthographic processing that offer various forms of noisy position or context-sensitive coding have revolutionized the field of visual word recognition. The influx of such models stems mainly from consistent findings, coming mostly from European languages, regarding an apparent insensitivity of skilled readers to letter order. Underlying the current revolution is the theoretical assumption that the insensitivity of readers to letter order reflects the (...) special way in which the human brain encodes the position of letters in printed words. The present article discusses the theoretical shortcomings and misconceptions of this approach to visual word recognition. A systematic review of data obtained from a variety of languages demonstrates that letter-order insensitivity is neither a general property of the cognitive system nor a property of the brain in encoding letters. Rather, it is a variant and idiosyncratic characteristic of some languages, mostly European, reflecting a strategy of optimizing encoding resources, given the specific structure of words. Since the main goal of reading research is to develop theories that describe the fundamental and invariant phenomena of reading across orthographies, an alternative approach to model visual word recognition is offered. The dimensions of a possible universal model of reading, which outlines the common cognitive operations involved in orthographic processing in all writing systems, are discussed. (shrink)

I have argued that orthographic processing cannot be understood and modeled without considering the manner in which orthographic structure represents phonological, semantic, and morphological information in a given writing system. A reading theory, therefore, must be a theory of the interaction of the reader with his/her linguistic environment. This outlines a novel approach to studying and modeling visual word recognition, an approach that focuses on the common cognitive principles involved in processing printed words across different writing systems. These claims were (...) challenged by several commentaries that contested the merits of my general theoretical agenda, the relevance of the evolution of writing systems, and the plausibility of finding commonalities in reading across orthographies. Other commentaries extended the scope of the debate by bringing into the discussion additional perspectives. My response addresses all these issues. By considering the constraints of neurobiology on modeling reading, developmental data, and a large scope of cross-linguistic evidence, I argue that front-end implementations of orthographic processing that do not stem from a comprehensive theory of the complex information conveyed by writing systems do not present a viable approach for understanding reading. The common principles by which writing systems have evolved to represent orthographic, phonological, and semantic information in a language reveal the critical distributional characteristics of orthographic structure that govern reading behavior. Models of reading should thus be learning models, primarily constrained by cross-linguistic developmental evidence that describes how the statistical properties of writing systems shape the characteristics of orthographic processing. When this approach is adopted, a universal model of reading is possible. (shrink)

For those working in Epistemology dizzying questions such as the following arise: - When are beliefs rational, or justified? - How should we update our beliefs in the light of new evidence? - Is it possible to gain knowledge, or justification? - How do we know what we know, and why do we care about whether--and what--others know? - How can the exploration of pre-Socratic philosophical questions about knowledge assist with the design of twenty-first-century computer interfaces? Addressing the need for (...) an authoritative and comprehensive reference work to enable users to answer these and other questions, and to make sense of--and to navigate around--an ever more complex corpus of scholarly literature, Epistemology is a new title in Routledge's acclaimed Critical Concepts in Philosophy series. Edited by Ram Neta, it is a four-volume collection which brings together foundational and the very best cutting-edge scholarship in a unique one-stop 'mini library'. Supplemented with a full index, and including an introduction to each volume, newly written by the editor, which places the assembled materials in their historical and intellectual context, Epistemology is destined to be valued by scholars and students as a vital research resource.

Seven decades ago, a new global order emerged. However, as the COVID-19 pandemic rages across the planet, those older ways of being are under unprecedented stress. Already, a new world order is taking shape--one that will put long-standing agenda items like trade, commerce and defence on the backburner. In a post-pandemic world, they will be edged out by issues like climate change, holistic healthcare, education for innovation and creativity, as well as the management of frontier technologies like artificial intelligence, robotics, (...) blockchain and big data. Human dignity and human rights will be critical issues in this modern reality. To represent the changed actuality of the twenty-first century, global governance needs fresh ideas and novel institutions. More than five decades ago, Deen Dayal Upadhyay articulated a coherent economic philosophy, at the core of which was human-centric development. In The Hindutva Paradigm, author and thinker Ram Madhav provides clarifying insights into the reasoning of a philosopher who has remained an enigma through the decades. At the crossroads where we stand, this refreshing and stimulating philosophy could be the answer to managing the new world order."--Amazon.com. (shrink)

I here describe meanings attributed to the term consciousness, extracted from the literature and from recent online discussions. Forty such meanings were identified and categorized according to whether they were principally about function or about experience; some overlapped but others were apparently mutually exclusive - and this list is by no means exhaustive. Most can be regarded as expressions of authors' views about the basis of con-sciousness, or opinions about the significance of aspects of its con-tents. The prospects for reaching (...) any single, agreed, theory independent definition of consciousness thus appear remote. How-ever, much confusion could be avoided if authors were always to spec-ify which aspects of consciousness they refer to when using the term. An example is outlined of how this can be done.

Basic philosophical concepts and major works of the Sautrantrika school in Buddhist philosophy; a study.

The Gita is a central text in Hindu traditions, and commentaries on it express a range of philosophical-theological positions. Two of the most significant commentaries are by Sankara, the founder of the Advaita or Non-Dualist system of Vedic thought and by Ramanuja, the founder of the Visistadvaita or Qualified Non-Dualist system. Their commentaries offer rich resources for the conceptualization and understanding of divine reality, the human self, being, the relationship between God and human, and the moral psychology of action and (...) devotion. This book approaches their commentaries through a study of the interaction between the abstract atman (self) and the richer conception of the human person. While closely reading the Sanskrit commentaries, Ram-Prasad develops reconstructions of each philosophical-theological system, drawing relevant and illuminating comparisons with contemporary Christian theology and Western philosophy.

In his recent Knowledge and its Limits, Timothy Williamson argues that no non-trivial mental state is such that being in that state suffices for one to be in a position to know that one is in it. In short, there are no “luminous” mental states. His argument depends on a “safety” requirement on knowledge, that one’s confident belief could not easily have been wrong if it is to count as knowledge. We argue that the safety requirement is ambiguous; on one (...) interpretation it is obviously true but useless to his argument, and on the other interpretation it is false. (shrink)

All rights reserved.Cell walls of grasses, including cereal crops and biofuel grasses, comprise the majority of plant biomass and intimately influence plant growth, development and physiology. However, the functions of many cell wall synthesis genes, and the relationships among and the functions of cell wall components remain obscure. To better understand the patterns of cell wall accumulation and identify genes that act in grass (...) cell wall biosynthesis, we characterized 30 samples from aerial organs of rice at 10 developmental time points, 3-100 d post-germination. Within these samples, we measured 15 cell wall chemical components, enzymatic digestibility and 18 cell wall polysaccharide epitopes/ligands. We also used quantitative reverse transcription-PCR to measure expression of 50 glycosyltransferases, 15 acyltransferases and eight phenylpropanoid genes, many of which had previously been identified as being highly expressed in rice. Most cell wall components vary significantly during development, and correlations among them support current understanding of cell walls. We identified 92 significant correlations between cell wall components and gene expression and establish nine strong hypotheses for genes that synthesize xylans, mixed linkage glucan and pectin components. This work provides an extensive analysis of cell wall composition throughout rice development, identifies genes likely to synthesize grass cell walls, and provides a framework for development of genetically improved grasses for use in lignocellulosic biofuel production and agriculture.

There is some consensus that for S to know that p, it cannot be merely a matter of luck that S’s belief that p is true. This consideration has led Duncan Pritchard and others to propose a safety condition on knowledge. In this paper, we argue that the safety condition is not a proper formulation of the intuition that knowledge excludes luck. We suggest an alternative proposal in the same spirit as safety, and find it lacking as well.
