The theme arises from the legal-academic movement "Law and Literature". This newly developed field should aim at two major goals, first, to investigate the meaning of law in a social context by questioning how the characters appearing in literary works understand and behave themselves to the law, and second, to find out a theoretical solution of the methodological question whether and to what extent the legal text can be interpreted objectively in comparison with the question how literary works should be (...) interpreted. The subject of justice and injustice has been covered not only in treatises of law and philosophy, but also in many works of literature: On the one hand, poets and writers have been outraged at the social conditions of their time. On the other hand, some of them have also contributed fundamental reflections on the idea of justice itself. (shrink)

The interaction between cavity modes and optical transitions leads to new coupled light-matter states in which the energy is periodically exchanged between the matter states and the optical mode. Here we present experimental evidence of optical strong coupling between modes of individual sub-wavelength metamaterial nanocavities and engineered optical transitions in semiconductor heterostructures. We show that this behaviour is generic by extending the results from the mid-infrared to the near-infrared. Using mid-infrared structures, we demonstrate that the light-matter coupling occurs at the (...) single resonator level and with extremely small interaction volumes. We calculate a mode volume of 4.9 × 10 from which we infer that only ~2,400 electrons per resonator participate in this energy exchange process. (shrink)

With the increasing degrees A.I.s and machines are applied across different social contexts, the need for implementing ethics in A.I.s is pressing. In this paper, we argue for a pluralist hybrid model for the implementation of moral A.I.s. We first survey current approaches to moral A.I.s and their inherent limitations. Then we propose the pluralist hybrid approach and show how these limitations of moral A.I.s can be partly alleviated by the pluralist hybrid approach. The core ethical decision-making capacity of an (...) A.I. based on the pluralist hybrid approach consists of two systems. The first is a deterministic algorithm system that incorporates different moral rules for making explicit moral decisions. The second is a machine learning system that calculates the value of the variables required by the application of moral principles. The pluralist hybrid system is better than the existing proposals as (i) it better addresses the moral disagreement problem of the top-down approach by including different moral principles, while (ii) it reduces the opacity of ethical decision-making compared with a bottom-up system by implementing explicit moral principles for moral decision making.

The surface grammar of reports such as ‘I have a pain in my leg’ suggests that pains are objects which are spatially located in parts of the body. We show that the parallel construction is not available in Mandarin. Further, four philosophically important grammatical features of such reports cannot be reproduced. This suggests that arguments and puzzles surrounding such reports may be tracking artefacts of English, rather than philosophically significant features of the world.

Graphical AbstractWhereas clathrin-mediated endocytosis (CME) exists in all eukaryotic cells, we first detect classical dynamin in Ichthyosporid, a single-cell, metazoan precursor. Based on a key functional residue in its pleckstrin homology domain, we speculate that the evolution of metazoan dynamin coincided with the specialized need for regulated CME during neurotransmission.

Ignorance is commonly assumed to be a lack of knowledge in Plato’s Socratic dialogues. I challenge that assumption. In the Protagoras, ignorance is conceived to be a substantive, structural psychic flaw—the soul’s domination by inferior elements that are by nature fit to be ruled. Ignorant people are characterized by both false beliefs about evaluative matters in specific situations and an enduring deception about their own psychic conditions. On my interpretation, akrasia, moral vices, and epistemic vices are products or forms of (...) ignorance, and a person who lacks knowledge is not necessarily ignorant. (shrink)

This paper critically surveys Adorno's dialectical-philosophical perspective of communication, which addresses a question and a quest for humanity: "How is communication possible?" In my view, any discussion of Adorno's view on communication should start with his distinction of two concepts: mediation and communication. Mediation involves the ideological critique of illusory relations of objectivity. Communication, defined by Adorno as the never-ending confrontation and reconciliation between subjectivity and objectivity, comes after the epistemological critique of objective mediation. Therefore, the quest for communication always (...) involves a never-ending wrestling between subject and object, particular and universal, experience and information. As Adorno would argue, true communication is "a result not an illusion o f (non-) identity of self and others. If any authentic mediated communication is humanly possible, it is because such communication is inscribed in a dialectical-dialogical process and it can only be accomplished momentarily. (shrink)

This paper critically evaluates Habermas's social-philosophical exploration of the public sphere in the age of mass communication, which addresses a key question: "Is the public possible in the sociohistorical formation of the mass public sphere?" In his genealogical analysis of different public spheres from feudal to modern times, Habermas indicates that the emergence of inter-subjectivity is historically based upon the dichotomy of private / public (subjective/objective). He emphasizes the opposition of the "subjective side" of rationality to its "objective side" while (...) dealing with the public spheres in different historical periods. Habermas points out that the notion of the public can exist only at the face-to-face level communication. It is impossible for the (impersonal) masses to construct any sense of publicness, since there are no historical and social conditions in which the masses of working class can establish an "autonomous private sphere" outside of material production and consumption, as the bourgeoisie did. In this way, Habermas ambivalently argues that the public is not possible in the mass public sphere. (shrink)

Confucianism advocates the lofty moral ideal of “humane love” (ren ai 仁愛) and condemns immoral actions. Strangely enough, however, Mencius, a “paradigmatic Confucian intellectual” who believed that “a true man cannot be corrupted by wealth, subdued by power, or affected by poverty” (Tu 1989a: 15), highly commended such typically corrupt actions as bending the law for the benefit of relatives or appointing people by mere nepotism when he talked about Shun 舜 in the text of the Mencius. In the first (...) four sections of this article, I will address the issue of how Confucianism encourages a special kind of corruption through its fundamentally consanguineous affection. Then, in the remaining sections, I will try to respond to some criticisms of my views by a few Chinese scholars. (shrink)

Artificial intelligence (AI) is increasingly expected to disrupt the ordinary functioning of society. From how we fight wars or govern society, to how we work and play, and from how we create to how we teach and learn, there is almost no field of human activity which is believed to be entirely immune from the impact of this emerging technology. This poses a multifaceted problem when it comes to designing and understanding regulatory responses to AI. This article aims to: (i) (...) defend the need for a novel conceptual model for understanding the systemic legal disruption caused by new technologies such as AI; (ii) to situate this model in relation to preceding debates about the interaction of regulation with new technologies (particularly the ‘cyberlaw’ and ‘robolaw’ debates); and (iii) to set out a detailed model for understanding the legal disruption precipitated by AI, examining both pathways stemming from new affordances that can give rise to a regulatory ‘disruptive moment’, as well as the Legal Development, Displacement or Destruction that can ensue. The article proposes that this model of legal disruption can be broadly generalisable to understanding the legal effects and challenges of other emerging technologies. (shrink)

This paper aims to produce a defense of the ethical significance of Confucian ritual. An adequate defense must explain how these conventions are based in a culturally-neutral, objective ground. After a brief account of how Confucians view the relationship between rituals and moral goodness, I consider three sorts of justification. Mencian naturalism appeals to a conception of flourishing that is grounded in human nature. Xunzian consequentialism looks to how ritual brings about social order. I argue that both of these approaches (...) fail because they are unable to account for the normative fineness of rituals, which refers to the precision and detail of ritual propriety. Instead, I look to Xunzi for a justification of rituals in terms of their role in beautifying human nature. I argue that this view provides a sort of objective ground for ritual, while also preserving their normative fineness. I conclude with remarks on how Xunzian aestheticism may be useful for understanding other areas of moral life. (shrink)

Shun argues that the distinction between first and third person is ill-suited to explain the complexities of anger. In this commentary, I first argue that, while the distinction is not uniquely important in characterizing anger and its variations, it can be distinctively important in illuminating the nature and normative significance of different forms of anger. Indeed, Shun’s own characterizations of anger in the paper seem to presuppose this importance. Secondly, I show that there are two related but distinct ways in (...) which one’s anger is ‘personally involved’: the first concerns how the offence is registered (e.g., whether it is perceived as targeting oneself), and the second concerns one’s emotional uptake of the offence. Lastly, I propose an alternative interpretation of Zhu Xi’s distinction between anger that ‘resides in things’ and anger that ‘resides in the self’, where the emphasis is not on whether anger is an appropriate response to a situation but on whether anger is properly encapsulated.

In many-valued logic the decision of functional completeness is a basic and important problem, and the thorough solution to this problem depends on determining all maximal closed sets in the set of many-valued logic functions. It includes three famous problems, i.e., to determine all maximal closed sets in the set of the total, of the partial and of the unary many-valued logic functions, respectively. The first two problems have been completely solved , and the solution to the third problem boils (...) down to determining all maximal subgroups in the k-degree symmetric group Sk, which is an open problem in the finite group theory. In this paper, all maximal closed sets in the set of unary p-valued logic functions are determined, where p is a prime. (shrink)

In this paper, I articulate three kinds of division that Plato and Aristotle acknowledge to be proper, valid methods of division, namely, diairesis, parallel division, and chiasmus. I attempt to explain the relationship among the three kinds of division, namely, how they transform from one to another. Starting with Plato’s division of constitution in the Statesman, I illuminate that from ostensible diairesis emerges a parallel division, and the parallel division causes a cross-division to occur. Thus, the sixfold division of constitution (...) is not a diairesis but rather is a 3 x 2 cross-division. Inheriting the three kinds of division from Plato, Aristotle advances the form by providing a theoretical explanation to the transformation of the three kinds of division. In Topics Z6, Aristotle prescribes two conditions under which a parallel division can originate from or construct ostensible diairesis and how the parallel division further causes a cross-division to occur.

In the debates on the roles of cultures in the ethics of human rights, one of them concerns Confucianism and Ubuntu, two prominent cultures in East Asia and Southern Africa, respectively. Some scholars assert that both cultures have values that are sharply different from the West, and conclude that the West should learn from these cultures. The aim of this paper is to philosophically investigate the roles of cultures in the ethics of human rights. I first introduce the works of (...) Bell, Metz and others on community values such as relationships and harmony in Confucianism and Ubuntu. I then argue that even if their interpretations were correct, their works still would not justify the conclusion they want. I show that it is better to use consequential evaluation rather than cultural evaluation to justify human rights. An example of human rights to health and privacy is discussed. This paper thus offers some preliminary but important philosophical investigations and addresses practical issues of consequential evaluation related to human rights. Keywords : Confucianism, Ubuntu, Cultural Evaluation, Consequential Evaluation, Human Rights, Health, Privacy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Awful Patriotism: Richard Rorty and the Politics of KnowingDavid Palumbo-Liu* (bio)Richard Rorty. Achieving Our Country: Leftist Thought in Twentieth-Century America. Cambridge: Harvard UP, 1998.This essay addresses the current debates surrounding what some have labeled the Two Lefts: a “cultural left” and an activist left. 1 Debate over this “divide” has made many strange bedfellows, but perhaps none quite so unheimlich as “liberal leftist” Richard Rorty and cultural conservative Harold (...) Bloom. To be sure, Rorty has often alluded to Bloom’s work, especially Bloom’s notion of “strong poets,” but in his most recent book, Rorty has appropriated Bloom in a particularly telling manner. In 1994, Harold Bloom published his polemic The Western Canon. At once eloquent and pathetic, it pressed all the right buttons. Bloom succinctly (or shall we say, reductively?) deployed his version of the “aesthetic” against any other approach. Cultural conservatives were gratified that someone of Bloom’s stature had done them the service of voicing their interests in a highly visible and contestatory manner; more moderate sorts squirmed uncomfortably at Bloom’s unabashed elitism and the shrillness of his tone; theorists and cultural studies folks were outraged at Bloom’s absolute ignorance of their work and his resort to parody instead of anything vaguely resembling an engaged critique; and ethnic, minority, queer, and feminist critics had more than enough to be insulted by in his racist and sexist arrogance. So far out is Bloom’s jeremiad that it probably came close to realizing his worst nightmare—it may have driven students screaming into all those horrid cultural studies classes to find out what was so seductive, so powerful as to corner The Canon. So I didn’t worry too much about The Western Canon. That is, until I read Richard Rorty’s essay “The Inspirational Value of Great Works of Literature” and its companion pieces in Achieving Our Country: Leftist Thought in Twentieth-Century America. What was Rorty, a self-proclaimed leftist, doing, calling to his aid the social and cultural archconservative Harold Bloom?In the first part of my essay I ponder this strange alliance, particularly as it joins forces against ethnic studies (to be sure, its common target is more generally “theory” of any stripe or color, but I want specifically to address the issue of ethnic literary study). Rorty adapts Bloom’s School of Resentment to characterize what he calls a certain, bad “knowingness,” against which he poses “hope” and “inspiration.” I want to examine more closely the nature and content of that destructive “knowledge,” for it becomes clear that [End Page 37] this knowledge is for Rorty the recognition of Otherness as a politically (as opposed to “merely” ontologically) functional identity. This knowledge is disturbing to Rorty and deeply informs his notions of “patriotism” and Americanism. For him, such knowledge impedes the formation of a leftist politics. It is precisely the disjunction between the “knowing” discourse of the cultural left obsessed with identity politics and an activist political left (modeled after the old reformist left) that troubles Rorty.My essay will be largely devoted to showing how Rorty’s recent work develops his earlier work on “ethnocentrism” into an “Americanism” that erodes precisely the liberal foundations of that earlier work and discloses the weakness of its claims. I understand this development as compelled by a certain impatience with identity politics that is shared by a number of liberal and leftist critics of American political society, an impatience fueled perhaps not so much by a conservative threat as by a perceived threat from “within” progressive politics. Basically, I ask, how and why are knowledge and recognition of “difference” taken to immobilize progressive politics? To frame that same question in a slightly different manner—what is the presumed content of that “progressive” politics, and what assumptions do we have to make in order to arrive at that point of view?Against the rather odd Bloom/Rorty pairing, set against “knowledge,” one would naturally seek out an enemies list for possible allies. Rorty in fact begins his essay by providing us with one in the figure of Fredric Jameson, an archpractitioner of theory whose “antiromantic” skepticism Rorty finds both debilitating and... (shrink)

Despite the productivity of basic cancer research, cancer continues to be a health burden to society because this research has not yielded corresponding clinical applications. Many proposed solutions to this dilemma have revolved around implementing organizational and policy changes related to cancer research. Here I argue for a different solution: a new conceptualization of causation in cancer. Neither the standard molecular biomarker approaches nor evolutionary biology approaches to cancer fully capture its complex causal dynamics, even when considered jointly. These approaches (...) map on to Ernst Mayr’s proximate–ultimate distinction, which is an inadequate conceptualization of causation in biological systems and makes it difficult to connect developmental and evolutionary viewpoints. I propose looking to evolutionary developmental biology to overcome the distinction and integrate the proximate and ultimate causal frameworks. I use the concepts of modularity and evolvability to show how an EvoDevo perspective can be manifested in cancer translational research. This perspective on causation in cancer is better suited for integrating the complexity of current empirical results and can facilitate novel developments in the investigation and clinical treatment of cancer.

In a group exam, students first do an exam individually and then redo the same exam in small groups. Studies have shown that group exams provide a number of benefits, including improvements in performance, learning, motivation, and preparation, as well as a reduction in anxiety. However, little has been written on whether group exams are fair. This paper aims to discuss and reject three fairness concerns that arise from (i) improved performance, (ii) improved learning, and (iii) accessibility. It also discusses (...) in detail the benefits of improved learning, arguing that they are the most valuable benefit which makes group exams particularly suitable for philosophy education. (shrink)

Cyclin-dependent kinase 5 has been implicated in Alzheimer's disease pathogenesis. Here, we demonstrate that overexpression of p25, an activator of cdk5, led to increased levels of BACE1 mRNA and protein in vitro and in vivo. A p25/cdk5 responsive region containing multiple sites for signal transducer and activator of transcription was identified in the BACE1 promoter. STAT3 interacts with the BACE1 promoter, and p25-overexpressing mice had elevated levels of pSTAT3 and BACE1, whereas cdk5-deficient mice had reduced levels. Furthermore, mice with a (...) targeted mutation in the STAT3 cdk5 responsive site had lower levels of BACE1. Increased BACE levels in p25 overexpressing mice correlated with enhanced amyloidogenic processing that could be reversed by a cdk5 inhibitor. These data demonstrate a pathway by which p25/cdk5 increases the amyloidogenic processing of APP through STAT3-mediated transcriptional control of BACE1 that could have implications for AD pathogenesis.

Causalists and Evidentialists can agree about the right course of action in an (apparent) Newcomb problem, if the causal facts are not as initially they seem. If declining $1,000 causes the Predictor to have placed $1m in the opaque box, CDT agrees with EDT that one-boxing is rational. This creates a difficulty for Causalists. We explain the problem with reference to Dummett's work on backward causation and Lewis's on chance and crystal balls. We show that the possibility that the causal (...) facts might be properly judged to be non-standard in Newcomb problems leads to a dilemma for Causalism. One horn embraces a subjectivist understanding of causation, in a sense analogous to Lewis's own subjectivist conception of objective chance. In this case the analogy with chance reveals a terminological choice point, such that either (i) CDT is completely reconciled with EDT, or (ii) EDT takes precedence in the cases in which the two theories give different recommendations. The other horn of the dilemma rejects subjectivism, but now the analogy with chance suggests that it is simply mysterious why causation so construed should constrain rational action. (shrink)

The year 1964 witnessed the polemics on "one divides into two" and "two combine into one" conducted in China's theoretical circles. Due to the sabotage of the "theoretical authority" and people like Guan Feng, this academic discussion was turned into a political mass criticism of the latter. During the Cultural Revolution, Lin Biao and the "gang of four" subjected comrades who advocated the theory of "two combine into one" or endorsed some of its viewpoints to brutal political persecution. Criticism of (...) the theory was a political frame-up. However, I think we should conduct realistic discussion and evaluation of it again as a theoretical issue, in the spirit of fostering democracy and "letting a hundred schools of thought contend." To my way of thinking, "two combine into one" is neither a metaphysical proposition nor a comprehensive generalization of the law of the unity of opposites. It is the generalization of the identity of contradiction in its first meaning. (shrink)

In this essay I review four recent monographs on Chinese American history: Xiao-huang Yin's Chinese American Literature since the 1850s, Madeline Hsu's Dreaming of Gold, Dream of Home: Transnationalism and Migration Between the United States and South China, Young Chen's Chinese San Francisco 1850-1943: A Trans-Pacific Community, and Xiaojian Zhao's Remaking Chinese America: Immigration, Family, and Community, 1940-1965. Based on both English- and Chinese-language sources, the authors of these four books explore migration processes and the social origins of Chinese immigrants (...) from an international perspective and they reinterpret the cultural values of immigrants as fundamentally open, engaged, and cosmopolitan. Moreover, they characterize the Chinese American community as a dynamic, fluid, and flexible global network and place Chinese America in a larger historical context beyond that of a single nation. They have seriously challenged the American-centered and nation-based research paradigm and promoted a more transnational, transcultural, and multilingual approach to the history of Asian American experience.

The book entitled the Huang Ti nei ching [Canonical Works of Huang Ti] has two sections - the "Su Wen" section and the "Ling Shu" section - and each section contains eighty-one articles. It was written by several authors in different historical periods. According to historical records and scholars' studies of the content and context of the book, we can roughly say that it was written in the period between the late years of the Warring States era and the early (...) years of the Eastern Han dynasty. Seven articles in the "Su Wen" section were materials from an "older version" and were merged into the book by Wang Fing in the Tang dynasty. They were probably written by scholars in the Eastern Han period or a little later. The two articles on acupuncture and pathology have been proved forgeries made in the Tang-Sung period. They should not have been included in the book because they contain more idealist dregs than do the other articles. (shrink)

In his classic book “the Foundations of Statistics” Savage developed a formal system of rational decision making. The system is based on (i) a set of possible states of the world, (ii) a set of consequences, (iii) a set of acts, which are functions from states to consequences, and (iv) a preference relation over the acts, which represents the preferences of an idealized rational agent. The goal and the culmination of the enterprise is a representation theorem: Any preference relation that (...) satisfies certain arguably acceptable postulates determines a (finitely additive) probability distribution over the states and a utility assignment to the consequences, such that the preferences among acts are determined by their expected utilities. Additional problematic assumptions are however required in Savage's proofs. First, there is a Boolean algebra of events (sets of states) which determines the richness of the set of acts. The probabilities are assigned to members of this algebra. Savage's proof requires that this be a σ-algebra (i.e., closed under infinite countable unions and intersections), which makes for an extremely rich preference relation. On Savage's view we should not require subjective probabilities to be σ-additive. He therefore finds the insistence on a σ-algebra peculiar and is unhappy with it. But he sees no way of avoiding it. Second, the assignment of utilities requires the constant act assumption: for every consequence there is a constant act, which produces that consequence in every state. This assumption is known to be highly counterintuitive. The present work contains two mathematical results. The first, and the more difficult one, shows that the σ-algebra assumption can be dropped. The second states that, as long as utilities are assigned to finite gambles only, the constant act assumption can be replaced by the more plausible and much weaker assumption that there are at least two non-equivalent constant acts. The second result also employs a novel way of deriving utilities in Savage-style systems -- without appealing to von Neumann-Morgenstern lotteries. The paper discusses the notion of “idealized agent" that underlies Savage's approach, and argues that the simplified system, which is adequate for all the actual purposes for which the system is designed, involves a more realistic notion of an idealized agent.
