– The paper explores first the postulational basis and significance of‘measures of information’in current information theory and their possible relations to physical entropy and Brillouin's‘negentropy’regarded as the negative of entropy. For some purposes, the same pattern or formal structure may be abstracted from both‘entropy’and‘information’. The paper analyzes, in the second place, the mathematical analogies which have been traced between information theory and quantum mechanics and argues that the analogies have but a limited value when we come to grips with the (...) deeper, and yet unsolved, problems of quantum theory. Lastly it is urged that the indiscriminate extensions of statistical and information‐theoretic methods, and of quantum‐mechanical analogies, e.g.‘linguistic duality’, to psycholinguistics, literary and aesthetic Gestalten, can result only in crude exaggerations. Dialectical methodology requires the continual reformulation of all scientific descriptions which have to reckon perpetually with the richness of human materials. (shrink)

This book presents a comprehensive exposition of Vedanta Desika`s Satadusani, a polemical classic of Visistadvaita Vedanta, devoted to the criticism of the doctrines of Advaita Vedanta. The thought-provoking arguments found in the Sixty-six Vedas of the original text are brought together, analysed and discussed in a systematic manner under eight broad headings: Pramanas Perception; Consciousness; Individual self; Brahman; Universe; Avidya; Sadhana and Mukti.In presenting the dialectics of Vedanta Desika in a vigorous and scholastic form the author deals with numerous issues (...) that the Vadas raise--epistemological, ontological, religious, and ethical. Thought the issues are many, each discussing a specific problem, they are ultimately directed to refute the central doctrine of Advaita, viz., that Brahman which is pure consciousness devoid of all determinations, constitutes the sole Reality and every thing else is illusory. While carefully tracing the fundamental differences between the two systems of Vedanta, he points out that the differences are mostly due to the difference in the stand-points they adopt.Faithfully conforming to the original in letter and spirit, this work will serve as a useful introduction to the study of the Sribhasya of Ramanuja. A distincy contribution to the study of classical Hindu thought, this book should be of interest to students of Philosophy in general and Vedanta in particular. (shrink)

Study of Adhikaraṇasārāvalī of Veṅkaṭanātha, 1268-1369, work on the fundamentals of Viśiṣṭādvaita philosophy.

Description: This scholarly work of Dr S.M.S. Chari's deals with the critical review of seventeen philosophical systems as presented in an important philosophical treatise of the thirteenth century titled Paramata-bhanga contributed by Vedanta Desika, an illustrious successor to Ramanuja, who is the chief exponent of Visistadvaita Vedanta. The main objective of Paramata-bhanga is to establish that Visistadvaita is a sound system of philosophy as compared to the several other Non-Vedic as well as Vedic schools and also Vedanta schools developed by (...) Samkara, Yadavaprakasa, Bhaskara, and other exponents of the post-Ramanuja period. The original text written in Manipravala (a mixture of Tamil and Sanskrit) language contains, besides a brief account of the fundamental doctrines of Visistadvaita. The schools covered are Carvaka, Buddhism, Jainism, Sankhya, Yoga, Vaisesika, Nyaya, Purvamimamsa, Pasupata, Sabdabrahma-vivartavada, and Advaita Vedanta. Among the extant philosophical classics, Paramata-bhanga is a unique work. Realizing the importance of the Paramata-bhanga for the comparative study of Indian philosophy, late Dr Chari tried to give a lucid exposition of this treatise in English. This volume, which is the first of its kind, would be invaluable for students of Indian philosophy in general and Visistadvaita in particular. (shrink)

On inquiring into the nature of the Charites one may be astonished at the disagreement of their compounding elements. On the one hand, they appear as the very representatives and even personification of gracefulness and charm, brightness, and joy; their name itself seems to testify this, closely allied as it is with the verb χαρειν besides the particular names of the most renowned Hesiodic trinity—Aglaia, Euphrosyne, and Thalia—that is to say, brilliancy, mirth, and florescence. Hence arose the Roman conception of (...) the Gratiae decentes; hence also the widespread neo-humanistic idea, clothed by Goethe in the well-known verse of the Classical Walpurgis Night: ‘Grace we are bringing into life ….’ But, on the other hand, we discover the incontestable kinship of Charis with Charon, the ugly and sullen ferryman of the lower world, the still more amazing relation between Eurynome, the mother of the Hesiodic trinity, and Eurynomos, the horrid demon of decay, the vulture-skinned devourer of putrefying corpses in the Delphic Nekyia of Polygnotos.

The development of sustainable agri-food systems requires not only new academic knowledge, but also concrete social and organizational change in practice. This article reflects on the action research process that supported and explored the learning process in an emerging agri-food value chain in the Berlin-Brandenburg region in eastern Germany. The action research study involved value chain actors, academic researchers, and process facilitators in a learning network. By framing the network’s learning and problem solving processes in concepts of organizational learning, lessons (...) were drawn for researchers and value chain developers. The results underline the importance of process facilitation in a learning value chain to create a social space, in which the actors in the value chain can interact and find a common basis for collaboration. In the learning process, facilitators used an iterative design to consistently align learning activities with the needs of practitioners to ensure practical relevance. To establish new practices and partnerships, value chain actors challenged existing routines and developed new ideas and visions, while at the same time improving established practices within their organizations and along the entire value chain.

The rapid economic growth and surge of consumerism in emerging markets have placed significant pressure on the environment and consumers. While well-researched ethical consumption remedies may be effective in the Western contexts, they may not be readily translatable in emerging markets due to institutional and socio-cultural differences. This research examines the popular practice of Danshari in China and investigates how this self-oriented practice leads to other-oriented ethical consumption behaviours. Using qualitative data gathered from online sharing and interviews, we unpack how (...) Danshari practitioners question and reshape their relationship with possessions and consumption to enhance their self-concept clarity. This clarified and elevated self-concept, in turn, leads to ethical consumption behaviours. Unlike Western ethical consumption concepts that are driven by principles or ideologies, Danshari’s essence of detachment, self-orientation, and action focus resonate with traditional Chinese teachings, providing a pragmatist approach to cultivating ethical consumption behaviours in China. This research adds to the growing body of pragmatism-based ethics research, expands the discussion of the link between consumption and the self, and offers valuable insights into promoting ethical consumerism in emerging markets.

The idea that mind and body are distinct entities that interact is often claimed to be incompatible with physics. The aim of this paper is to disprove this claim. To this end, we construct a broad mathematical framework that describes theories with mind-body interaction (MBI) as an extension of current physical theories. We employ histories theory, i.e., a formulation of physical theories in which a physical system is described in terms of (i) a set of propositions about possible evolutions of (...) the system and (ii) a probability assignment to such propositions. The notion of dynamics is incorporated into the probability rule. As this formulation emphasises logical and probabilistic concepts, it is ontologically neutral. It can be used to describe mental `degrees of freedom' in addition to physical ones. This results into a mathematical framework for psycho-physical interaction (ΨΦI formalism). Interestingly, a class of ΨΦI theories turns out to be compatible with energy conservation. (shrink)

The aim of this paper is to offer a concise and faithful account of Rawls’ theory of international justice, in an effort, first, to elucidate the structure of the argument that is advanced in that theory and, second, to present a critical assessment of it. The critical assessment section attempts, on the one side, to cope with crucial methodological issues, which have a more general bearing upon Rawls’ overall political philosophical position, including the constructivist perspective of theory making and the (...) division between a political conception and a comprehensive doctrine; on the other side, to weigh up a set of substantive claims made in the Rawlsian theory of international justice, including the recognition of peoples as the fundamental subjects of international law, the toleration of the so-called decent peoples and the considerably thin construal of human rights encompassed in The Law of Peoples. The paper attempts to provide a series of reasons that could be well-suited to explicate its author’s doubts about the soundness of the Rawlsian theoretical perspective with regard to both its formal methodological features and its more content-oriented convictions.

We demonstrate in this paper that the probabilities for sequential measurements have features very different from those of single-time measurements. First, they cannot be modelled by a classical stochastic process. Second, they are contextual, namely they depend strongly on the specific measurement scheme through which they are determined. We construct Positive-Operator-Valued measures (POVM) that provide such probabilities. For observables with continuous spectrum, the constructed POVMs depend strongly on the resolution of the measurement device, a conclusion that persists even if we (...) consider a quantum mechanical measurement device or the presence of an environment. We then examine the same issues in alternative interpretations of quantum theory. We first show that multi-time probabilities cannot be naturally defined in terms of a frequency operator. We next prove that local hidden variable theories cannot reproduce the predictions of quantum theory for sequential measurements, even when the degrees of freedom of the measuring apparatus are taken into account. Bohmian mechanics, however, does not fall in this category. We finally examine an alternative proposal that sequential measurements can be modeled by a process that does not satisfy the Kolmogorov axioms of probability. This removes contextuality without introducing non-locality, but implies that the empirical probabilities cannot be always defined (the event frequencies do not converge). We argue that the predictions of this hypothesis are not ruled out by existing experimental results (examining in particular the “which way” experiments); they are, however, distinguishable in principle.

This is a textbook on quantum mechanics. It is addressed to graduates and advanced undergraduates. The book presents quantum theory as a logically coherent system, placing stronger emphasis on the theory' s probabilistic structure and on the role of symmetries. It makes students aware of foundational problems from the very beginning, but at the same time, it urges them to adopt a pragmatic attitude towards the quantum formalism. The book consists of five parts. Part I is a review of classical (...) physics, including probability theory, and a historical introduction to quantum theory. Part II presents quantum theory in terms of six fundamental principles. The principles are presented together with the necessary mathematical background and with applications to simple systems. Part III analyses the properties of quantum particles. It starts with the description of symmetries, continues to non-relativistic particles, the introduction of spin, and particle statistics. It concludes with a symmetries-based introduction to relativistic quantum systems and with the first steps towards relativistic quantum field theory. Part IV presents techniques adapted to specific problems: the structure and spectra of composite systems, decays and transitions, particle scattering, and open quantum systems. Finally, Part V revisits quantum foundations: quantum measurement theory, the major interpretations of quantum theory, and the frontiers of quantum theory in contemporary research. (shrink)
