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 Sāṃkhya similes are an important means to communicate basic philosophical teachings. In the texts similes are frequently used, especially in the Sāṃkhya passages in the Mahābhārata, in the Sāṃkhyakārikā and in the Sāṃkhyasūtra. This paper compares the similes in these three texts and analyses changes in the philosophy as revealed in the similes. A comparison of the similes of Sāṃkhya texts produced over more than one thousand years reveals changes in the emphasis in this philosophical system. The purpose of the similes in the Sāṃkhya passages of the Mahābhārata is to produce an intuitive understanding of the separateness of puruṣa and prakṛti. The similes are designed to lead the listener to understand this basic dualism. In the Sāṃkhyakārikā the most difficult issues are the relationship between prakṛti and puruṣa and the idea of prakṛti working for the salvation of puruṣa. One whole chapter of the Sāṃkhyasūtra is devoted to similes.  相似文献

The literature of Bhartṛhari and Maṇḍana attention in contemporary times. The writings of the prominent linguistic philosopher and grammarian Bhartṛhari and of Manḍana, an encyclopedic scholar of later seventh century and most likely a senior contemporary of Śaṅkara, shape Indian philosophical thinking to a great extent. On this premise, this study of the influence of Bhartṛhari on Maṇḍana’s literature, the scope of this essay, allows us to explore the significance of Bhartṛhari’s writings, not only to comprehend the philosophy of language, but also to understand the contribution of linguistic philosophy in shaping Advaita philosophy in subsequent times. This comparison is not to question originality on the part of Maṇḍana, but rather to explore the interrelationship between linguistic philosophy and the monistic philosophy of the Upaniṣadic tradition. Besides excavating the role of Bhartṛhari writings on the texts of Maṇḍana, analysis this will reveal the interrelatedness of the Advaita school of Śaṅkara often addressed as ‘pure non-dualism’ (Kevalādvaita) and the Advaita of Bhartṛhari, identified as ‘non-dualism of the word-principle’ (Śabdādvaita).  相似文献

It has become commonplace in introductions to Indian philosophy to construe Plato’s discussion of forms (εἶδος/ἰδέα) and the treatment in Nyāya and Vaiśeṣika of universals (sāmānya/jāti) as addressing the same philosophical issue, albeit in somewhat different ways. While such a comparison of the similarities and differences has interest and value as an initial reconnaissance of what each says about common properties, an examination of the roles that universals play in the rest of their philosophical enquiries vitiates this commonplace. This paper draws upon the primary texts to identify the following metaphysical, epistemological, semantic and soteriological roles that universals play in the philosophy of Plato and of Nyāya and Vaiśeṣika:
Metaphysical: causal of the existence of x Metaphysical: constitutive of the identity/essence of x Epistemological: cognitively causal (i.e. of the cognition of one over many) Epistemological: epistemically causal (i.e. of knowledge of x) Semantic: necessary condition of speech and reason Epistemological: vindicatory of induction (Nyāya only) Metaphysical: explanatory of causation (Nyāya only) Soteriological: cathartic contemplation (Plato only)
These roles provide us with motivations or reasons to believe that universals exist. As we examine these motivations, we find pressures mounting against our assimilating Platonic forms and the universals of Nyāya and Vaiśeṣika in the discourse about common properties. It is especially when we appreciate the utterly different contribution that universals make in securing our highest welfare that we realize how Plato and the two sister schools are not so much talking somewhat differently about the same thing, but talking somewhat similarly about different things. This better understanding of this difference in these philosophies opens a route for our better understanding of their unique contributions in the ongoing dialogue of philosophy.  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 paper surveys the key terms śaktipāta and samāveśa (both of which refer to religious experience) in the primary sources of Tantric Śaivism over several centuries of textual development, building up a theory as to their range of meanings. It specifically focuses on their usage by Abhinavagupta (Kāshmīr, 10th century) by presenting a complete translation of chapter 11 of his Tantrasāra. The paper thus serves to (a) illuminate the nature of spiritual experience and the qualifcations for religious praxis in Śaivism, (b) give insight into the worldview of the Tantric Śaivas, and (c) help in pinpointing a specific and significant issue in the phenomenological study of religion generally. An earlier version of this paper has been published in a somewhat different form in Evam: Forum on Indian Representations vol. 4, published by Samvad India, New Delhi, India. This paper could not have been written without two years of intensive study with Professor Alexis Sanderson of All Souls College, Oxford, whose scholarship has proved essential in advancing my understanding of Śaivism. Also very helpful was Dr. Somadeva Vasudeva, now of Columbia University, whose database and encyclopedic knowledge have been invaluable. The germ of the idea for this article was suggested to me when Professor Paul Muller-Ortega (University of Rochester) first pointed out to me the passage beginning at MVT 2.14.  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

This paper is a preparatory analysis for a jurisprudence of the singular. Through a critical analysis of the negativity and the absolving character of the transcendental metaphysics of law and justice it reads mainly through M. Heidegger, Heraclitus, G. Agamben and J-L. Nancy a realignment of the questioning of justice that takes its provisional name in ‘dike’, at thepoint where the routes of ontology, the juridical and the political intersect and reveal the pseudo-propriety of their presuppositions. Without the transcendental dialectical discourse of the origin and its absolving-absolute ‘ends’, this paper re-poses the urgency of thinking the singular-multiple ‘right’ otherwise. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

In this paper, the problem of illusory perception, as approached by the Nyāya and Advaita Vedānta schools of philosophy, is discussed from the standpoint of the Parimala. This seminal work belonging to the Bhāmatī tradition of Advaita Vedānta was composed in the sixteenth century by the polymath Appaya Dīk?ita. In the context of discussing various theories of illusion, Dīk?ita dwells upon the Nyāya theory of anyathākhyāti, and its connection with jñānalak?a?apratyāsatti as a causal factor for perception, and closely examines if such an extraordinary (alaukika) perception is tenable to explain illusory perception. He then proceeds to point out the deficiencies of this model and thereby brings to the fore the anirvacanīyakhyāti of Advaitins as the only theory which stands scrutiny.  相似文献
