The concept of avidyā is one of the central categories in the Advaita of Śaṇkara and Maṇḍana. Shifting the focus from māyā, interpreted either as illusion or as the divine power, this concept brings ignorance to the forefront in describing duality and bondage. Although all Advaitins accept avidyā as a category, its scope and nature is interpreted in multiple ways. Key elements in Maṇḍana’s philosophy include the plurality of avidyā, individual selves as its substrate and the Brahman as its field (viṣaya), and the distinction in avidyā between non-apprehension and misapprehension. A closer investigation shows that Maṇḍana is directly influenced by Bhartṛhari’s linguistic non-dualism in developing the concept of avidyā. This study also compares other key constituents such as vivartta and pariṇāma that are relevant to the analysis of avidyā. As the concept of counter-image (pratibimba) emerges as a distinct stream of Advaita subsequent to Maṇḍana, this study also compares the application of pratibimba in the writings of Bhartṛhari and Maṇḍana.  相似文献

In this article we compare the propensity to intermarry of various migrant groups and their children who settled in Germany, France, England, Belgium and the Netherlands in the post-war period, using a wide range of available statistical data. We try to explain different intermarriage patterns within the framework of Alba and Nee's assimilation theory and pay special attention to the role of religion, colour and colonial background. We therefore compare colonial with non colonial migrants and within these categories between groups with ‘European’ (Christian) and non-European (Islam, Hinduism) religions. First of all, religion appears to be an important variable. Migrants whose faith has no tradition in Western Europe intermarry at a much lower rate than those whose religious backgrounds correspond with those that are common in the country of settlement. The rate of ethnic endogamous marriages in Western Europe are highest in Hindu and Muslim communities, often regardless if they came as guest workers or colonial migrants. Whereas differences in religion diminish the propensity to intermarry, colour or ‘racial’ differences on the other hand seem to be less important. This is largely explained by the pre-migration socialisation. Furthermore, the paper argues that the attention to institutions, as rightly advocated by Richard Alba and Victor Nee, needs a more refined and layered elaboration. Institutions, often as barriers to intermarriage, do not only emanate from the receiving society, but also—be it less formalized—within migrant communities. Especially religions and family systems, but also organized nationalist feelings, can have a profound influence on how migrants think about endogamy. Finally, strong pressures to assimilate, often through institutionalized forms of discrimination and stigmatization, not only produce isolation and frustrate assimilation (with resulting low intermarriage rates), but can also stimulate assimilation by 'passing' mechanisms. These factors, together with a more comparative perspective, are not completely ignored in the new assimilation theory, but—as this study of Western European intermarriage patterns stresses—deserve to be included more systematically in historical and social scientist analyses.  相似文献

In his twelfth century alaṃkāraśāstra, the Candrāloka, Jayadeva Pīyūṣavarṣa reverses the sequence of topics found in Mammaṭa’s Kāvyapr-akāśa, an earlier and immensely popular work. With such a structural revisionism, Jayadeva asserts the autonomy of his own work and puts forth an ambitious critique of earlier approaches to literary analysis. Jayadeva investigates the technical and aesthetic components of poetry in the first part of the Candrāloka, prior to his formal semantic investigations in the latter half of the text, thus suggesting that aesthetic evaluations of poetry beneficially inform scientific investigations of language. Jayadeva’s organization of his chapters on the semantic operations, moreover, intimates that the study of suggestive and metaphoric functions of language clarifies our understanding of denotation, which is conventionally understood to be the primary and direct path of verbal designation.  相似文献

Huntington (2007); argues that recent commentators (Robinson, 1957; Hayes, 1994; Tillemans, 1999; Garfield and Priest, 2002) err in attributing to Nāgārjuna and Candrakīrti a commitment to rationality and to the use of argument, and that these commentators do violence to the Madhyamaka project by using rational reconstruction in their interpretation of Nāgārjuna’s and Candrakīrti’s texts. Huntington argues instead that mādhyamikas reject reasoning, distrust logic and do not offer arguments. He also argues that interpreters ought to recuse themselves from argument in order to be faithful to these texts. I demonstrate that he is wrong in all respects: Nāgārjuna and Candrakīrti deploy arguments, take themselves to do so, and even if they did not, we would be wise to do so in commenting on their texts.  相似文献

Sanskrit poeticians make the visionary faculty of pratibhā a necessary part of the professional poet’s make-up. The term has a pre-history in Bhartṛhari’s linguistic metaphysics, where it is used to explain the unitary perception of meaning. This essay examines the relation between pratibhā and possible theories of the imagination, with a focus on three unusual theoreticians—Rājaśekhara, Kuntaka, and Jagannātha Paṇḍita. Rājaśekhara offers an analysis of pratibhā that is heavily interactive, requiring the discerning presence of the bhāvaka listener or critic; he also positions pratibhā in relation to Bildung (vyutpatti) and practice. For Kuntaka, pratibhā, never an ex nihilo creation by a poet, serves as the basis for the peculiar forms of intensified insight and experience that constitute poetry; these may also involve the creative scrambling and re-articulation of the object in terms of its systemic composition. At times, Kuntaka’s pratibhā comes close to a strong notion of imaginative process. But the full-fledged thematization of the imagination, and of pratibhā as its support and mechanism, is best seen in the seventeenth-century debates preserved for us by Jagannātha. A link is suggested between the discourse of poetic imagination in Jagannātha and similar themes that turn up in Indo-Persian poets such as Bedil.  相似文献

Too many youth and young adults find themselves on the streets, couch‐surfing with friends, in emergency shelters or worse, after exiting the child welfare and juvenile justice systems. In some circumstances, youth have had court hearings until their exit from the legal system, but those hearings have not focused on long‐range plans of youth and emergencies youth may encounter. In other circumstances, there has been little or no planning prior to discharge, especially for young people who leave the juvenile justice system. Courts can and should prevent, alleviate or end youth homelessness for youth who appear before them through strategies that are enumerated in the recently‐passed NCJFCJ resolution. This article expounds on three of these strategies – coordinating transition and re‐entry plans, insisting on effective legal representation of youth, and utilizing sound judicial leadership. It also describes the concurrent efforts of the Coalition for Juvenile Justice and the American Bar Association's Homeless Youth Legal Network to remove legal barriers and improve outcomes for youth and young adults experiencing homelessness.  相似文献

Evaluation appointment orders provide enforceable scaffolding for conduct of family court parenting plan evaluations, and use of the evaluator's reports, feedback, file, and testimony. Unlike a contract, a stipulated or adjudicated appointment order is directly enforceable by the family court. It unambiguously positions the evaluator as the family court's appointee – answerable directly to the court and, in some jurisdictions, protected by quasi-judicial immunity from damages claims. A well-crafted appointment order governs the roles and expectations of the court, the evaluator, the parties, the lawyers, and the collateral witnesses. An appointment order mandates the legal duties, rights, powers, and responsibilities of the professionals, the parties, and the collateral witnesses. At minimum, an appointment order articulates the legal basis for the appointment, the purpose and scope of the evaluation, compensation of evaluator, and the duty of the parties to participate in the process. A written evaluation protocol or procedures statement discloses in advance the methods of investigation and assessment that the evaluator intends to use. Together, the appointment order and written protocol help the evaluator, lawyers, parents, and judge manage the complexity of the evaluation process.  相似文献

This article argues for a new interpretation of the Sanskrit compound gaṇḍa-vyūha as it is used in the common title of the Mahāyāna text the Gaṇḍavyūha-Sūtra.The author begins by providing a brief history of the sūtra’s appellations in Chinese and Tibetan sources. Next, the meanings of gaṇḍa (the problematic member of the compound) are explored. The author proposes that contemporary scholars have overlooked a meaning of gaṇḍa occurring in some compounds, wherein gaṇḍa can mean simply “great,” “big” or “massive.” This general sense is particularly common in the compound gaṇda-śaila (a “massive rock” or “boulder”) and is found in such texts as the Bhāgavata Purāṇa, the Harivaṃśa and the Harṣacarita. Following the discussion of Gaṇḍa, the author examines the term vyūha (“array”) as it is used in the Gaṇḍavyūha-sūtra. The article concludes with the suggestion that a more appropriate translation of the Gaṇḍavyūha-sūtra would be “The Supreme array Scripture.”  相似文献

The concept of avidyā or ignorance is central to the Advaita Vedāntic position of Śȧnkara. The post-Śaṅkara Advaitins wrote sub-commentaries on the original texts of Śaṅkara with the intention of strengthening his views. Over the passage of time the views of these sub-commentators of Śaṅkara came to be regarded as representing the doctrine of Advaita particularly with regard to the concept of avidyā. Swami Satchidanandendra Saraswati, a scholar-monk of Holenarsipur, challenged the accepted tradition through the publication of his work Mūlāvidyānirāsaḥ, particularly with regard to the avidyādoctrine. It was his contention that the post-Śaṅkara commentators brought their own innovations particularly on the nature of avidyā. This was the idea of mūlāvidyā or ‘root ignorance’, a positive entity which is the material cause of the phenomenal world. Saraswati argues that such an idea of mūlāvidyā is not to be found in the bhāṣyas (commentaries) of Śaṅkara and is foisted upon Śaṅkara. This paper attempts to show that although Śaṅkara may not have explicitly favoured such a view of mūlāvidyā, his lack of clarity on the nature of avidyā left enough scope for the post-Śaṅkara commentators to take such a position on avidyā.  相似文献

Luminol, leuchomalachite green, phenolphthalein, Hemastix, Hemident, and Bluestar are all used as presumptive tests for blood. In this study, the tests were subjected to dilute blood (from 1:10,000 to 1:10,000,000), many common household substance, and chemicals. Samples were tested for DNA to determine whether the presumptive tests damaged or destroyed DNA. The DNA loci tested were D2S1338 and D19S433. Leuchomalachite green had a sensitivity of 1:10,000, while the remaining tests were able to detect blood to a dilution of 1:100,000. Substances tested include saliva, semen, potato, tomato, tomato sauce, tomato sauce with meat, red onion, red kidney bean, horseradish, 0.1 M ascorbic acid, 5% bleach, 10% cupric sulfate, 10% ferric sulfate, and 10% nickel chloride. Of all the substances tested, not one of the household items reacted with every test; however, the chemicals did. DNA was recovered and amplified from luminol, phenolphthalein, Hemastix, and Bluestar, but not from leuchomalachite green or Hemident.  相似文献
