论公民身份的二重性

公民的概念和公民身份理论是当代政治、社会和法律理论领域中的核心概念,近些年逐渐成为了中国学界关注的理论焦点之一,而对公民身份的基本内涵和属性却缺乏相应深入的研究和了解.本文从内在逻辑和演进脉络两个方面入手,讨论了公民身份本身固有的三对矛盾统一体即二重性,即民族性与世界性,权利性与责任性,私人性与公共性.相信通过对公民身份二重性的充分认识,对于培养"好公民"、构建社会主义和谐社会有着重要的参照和借鉴作用.     

世界二元分裂的意义与困境--从科西克的《具体辩证法》说起

世界二元分裂是一种比较普遍的批判理论模式,科西克也走入了它的窠臼,阐述他富有存在主义色彩的"马克思主义".从科西克的《具体辩证法》说起,我们发现,世界二元分裂具有久远的历史,它具有重要的批判价值和人性意义,然而也存在着内在的缺陷,在理论上和实践上必然陷入难以自拔的困境.马克思主义对世界二元分裂的成功扬弃,体现了其学说的实践精神和科学精神.     

证券资本及其二重性分析

证券资本是指证券法所调整的各类社会关系中参与直接投/融资活动之货币运动的总和,货币是证券资本的主要表现形式。无论是资本形态还是资本规模,证券资本均与公司资本存在重大差别,公司资本仅是证券资本之发行资本的一部分。以证券法所调整的社会关系分析,证券资本二重性最直观的表现是发行资本和交易资本,而其本质是实体资本和虚拟资本;广义地看,证券资本二重性又表现为境内资本和境外资本、自有资本和非自有资本、长期资本和短期资本。证券资本及其二重性是证券立法中若干二元结构性问题的基础。     

Priestley Duality for Bilattices

We develop a Priestley-style duality theory for different classes of algebras having a bilattice reduct. A similar investigation has already been realized by B. Mobasher, D. Pigozzi, G. Slutzki and G. Voutsadakis, but only from an abstract category-theoretic point of view. In the present work we are instead interested in a concrete study of the topological spaces that correspond to bilattices and some related algebras that are obtained through expansions of the algebraic language.     

A Coalgebraic View of Heyting Duality

We give a coalgebraic view of the restricted Priestley duality between Heyting algebras and Heyting spaces. More precisely, we show that the category of Heyting spaces is isomorphic to a full subcategory of the category of all -coalgebras, based on Boolean spaces, where is the functor which maps a Boolean space to its hyperspace of nonempty closed subsets. As an appendix, we include a proof of the characterization of Heyting spaces and the morphisms between them.     

Presuppositions as Anaphoric Duality Enablers

The key to an adequate account of presupposition projection is to accommodate the fact that the presuppositions of a sentence cannot always be read off the sentence but can often be identified only on the basis of prior utterances in the conversation in which the sentence is uttered. In addition, an account of presupposition requires a three-valued semantics of assertibility and deniability in a context. Presuppositions can be explicated as sentences that belong to the conversation and the assertibility of which ensures that the remaining assertibility and deniability conditions of the presupposition-bearing sentence are dual to one another. The prevailing approach to presuppositions, grounded in Heim’s context-change semantics, can be criticized both on philosophical grounds and for failing to accommodate the phenomena.     

Duality for algebras of relevant logics

This paper defines a category of bounded distributive lattice-ordered grupoids with a left-residual operation that corresponds to a weak system in the family of relevant logics. Algebras corresponding to stronger systems are obtained by adding further postulates. A duality theoey piggy-backed on the Priestley duality theory for distributive lattices is developed for these algebras. The duality theory is then applied in providing characterizations of the dual spaces corresponding to stronger relevant logics.The author gratefully acknowledges the support of the National Sciences and Engineering Research Council of Canada.     

Priestley Duality for Quasi-Stone Algebras

In this paper we describe the Priestley space of a quasi-Stone algebra and use it to show that the class of finite quasi-Stone algebras has the amalgamation property. We also describe the Priestley space of the free quasi-Stone algebra over a finite set. This revised version was published online in June 2006 with corrections to the Cover Date.     

A Duality for Involutive Bisemilattices

Studia Logica - We establish a duality between the category of involutive bisemilattices and the category of semilattice inverse systems of Stone spaces, using Stone duality from one side and the...     

The Duality of American Christian Nationalism: Religious Traditionalism versus Christian Statism

While posited as a unified ideology, Christian Nationalism (CN) actually contains two distinct views of what it means to be a “Christian Nation”—one which envisions a Christian civil society separate from the profanities of politics, what we call “Religious Traditionalism.” The other envisions a Christian federal government where power is wielded exclusively by ethno-religious insiders, or “Christian Statism.” Multiple waves of two national surveys confirm that current measures of CN contain these two factors, which have become increasingly divergent in the past 20 years. In addition, we find that Christian Statism predicts nativism, Islamophobia, anti-Semitism, and racial distrust while Religious Traditionalism, in most instances, predicts the opposite. Historically, Religious Traditionalists have always sought to influence civil society and focused mainly on family/sexual issues. But a different brand of CN has emerged, wherein all federal and state authority should rightfully and exclusively belong to Christian Statists.     

The Content of Deduction

For deductive reasoning to be justified, it must be guaranteed to preserve truth from premises to conclusion; and for it to be useful to us, it must be capable of informing us of something. How can we capture this notion of information content, whilst respecting the fact that the content of the premises, if true, already secures the truth of the conclusion? This is the problem I address here. I begin by considering and rejecting several accounts of informational content. I then develop an account on which informational contents are indeterminate in their membership. This allows there to be cases in which it is indeterminate whether a given deduction is informative. Nevertheless, on the picture I present, there are determinate cases of informative (and determinate cases of uninformative) inferences. I argue that the model I offer is the best way for an account of content to respect the meaning of the logical constants and the inference rules associated with them without collapsing into a classical picture of content, unable to account for informative deductive inferences.     

Priestley Style Duality for Distributive Meet-semilattices

We generalize Priestley duality for distributive lattices to a duality for distributive meet-semilattices. On the one hand, our generalized Priestley spaces are easier to work with than Celani??s DS-spaces, and are similar to Hansoul??s Priestley structures. On the other hand, our generalized Priestley morphisms are similar to Celani??s meet-relations and are more general than Hansoul??s morphisms. As a result, our duality extends Hansoul??s duality and is an improvement of Celani??s duality.     

Free Modal Lattices via Priestley Duality

A Priestley duality is developed for the variety j of all modal lattices. This is achieved by restricting to j a known Priestley duality for the variety of all bounded distributive lattices with a meet-homomorphism. The variety j was first studied by R. Beazer in 1986.The dual spaces of free modal lattices are constructed, paralleling P.R. Halmos' construction of the dual spaces of free monadic Boolean algebras and its generalization, by R. Cignoli, to distributive lattices with a quantifier.     

The Content of Emotional Thoughts

Abstract

In this paper I examine Peter Goldie's theory of emotional thoughts and feelings, offered in his recent book The Emotions and subsequent articles. Goldie argues that emotional thoughts cannot be assimilated to belief or judgment, together with some added-on phenomenological component, and on this point I agree with him. However, he also argues that emotionally-laden thoughts, thoughts had, as he puts it, ‘with feeling,’ in part differ from unemotional thoughts in their content. The thought ‘the gorilla is dangerous’ when thought with an emotional feeling of fear differs in its content from the thought ‘the gorilla is dangerous’ when thought without actually feeling fear. I argue that Goldie offers no good reason to think that the difference between emotional and unemotional thoughts is found in their contents. In fact, the analogies Goldie presents to help make his case actually suggest that the contribution feelings make to the distinctive role played by emotional thoughts consists solely in their influencing the way we think emotional thoughts. However, this position is consistent with Goldie's broader point: that theories which treat emotional feelings as phenomenological afterthoughts should be rejected.     

Duality and nonduality in meditation research

The great variety of meditation techniques found in different contemplative traditions presents a challenge when attempting to create taxonomies based on the constructs of contemporary cognitive sciences. In the current issue of Consciousness and Cognition, Travis and Shear add ‘automatic self-transcending’ to the previously proposed categories of ‘focused attention’ and ‘open monitoring’, and suggest characteristic EEG bands as the defining criteria for each of the three categories. Accuracy of current taxonomies and potential limitations of EEG measurements as classifying criteria are discussed.     

The Double Content of Perception

Clearly we can perceive both objects, and various aspects or appearances of those objects. But how should that complexity of perceptual content be explained or analyzed? I argue that perceptual representations normally have a double or two level nested structure of content, so as to adequately incorporate information both about contextual aspects Y(X) of an object X, and about the object X itself. On this double content (DC) view, perceptual processing starts with aspectual data Y′(X′) as a higher level of content, which data does not itself provide lower level X-related content, but only an aspectually encoded form of such data. Hence the relevant perceptual data Y′(X′) must be ’de-contextualized’ or decoded to arrive at the X-related content X′, resulting in a double content structure for perceptual data, that persists in higher-order conscious perceptual content. Some implications and applications of this DC view are also discussed.
