This article develops and defends a new functional approach to scientific progress. I begin with a review of the problems of the traditional functional approach. Then I propose a new functional account of scientific progress, in which scientific progress is defined in terms of usefulness of problem defining and problem solving. I illustrate and defend my account by applying it to the history of genetics. Finally, I highlight the advantages of my new functional approach over the epistemic and semantic approaches (...) and dismiss some potential objections to my approach. (shrink)

The functional approach to scientific progress has been mainly developed by Kuhn, Lakatos, Popper, Laudan, and more recently by Shan. The basic idea is that science progresses if key functions of science are fulfilled in a better way. This chapter defends the function approach. It begins with an overview of the two old versions of the functional approach by examining the work of Kuhn, Laudan, Popper, and Lakatos. It then argues for Shan’s new functional approach, in which scientific (...) progress is defined as an increase of usefulness of exemplary practices. (shrink)

Philosophical progress is one of the most controversial topics in metaphilosophy. It has been widely debated whether philosophy makes any progress in history. This paper revisits the concept of philosophical progress. It first identifies two criteria of an ideal concept of philosophical progress. It then argues that our accounts of philosophical progress fail to provide such an ideal concept. Finally, it argues that not only do we not have a good concept of philosophical progress, we also do not need a (...) concept of philosophical progress in order to arrive at a good understanding of the history of philosophy.

It has been widely received that one of Gregor Mendel’s most important contributions to the history of genetics is his novel work on developmental information (for example, the proposal of the famous Mendelian ratios like 1:2:1, 3:1, and 9:3:3:1). This view is well evidenced by the fact that much of early Mendelians’ work in the 1900s focuses on the retrodiction (viz. the re-analysis of the pre-exist data with Mendel’s approach). However, there is no consensus on what Mendel meant by development (...) (Entwicklung). Nor is there an agreement on the interpretation of Mendel’s laws of developmental series (Entwicklungsreihe). This chapter revisits Mendel’s notions of development and developmental series. Firstly, I argue that Mendel’s use of development is greatly influenced by Gärtner’s. Secondly, I show Mendel’s work on developmental series are novel and important for its new ways of experimentation, conceputalisation, and analysis. Thirdly, I argue that Mendel’s laws of developmental information were not about heredity. (shrink)

Alexander Bird indicates that the significance of Thomas Kuhn in the history of philosophy of science is somehow paradoxical. On the one hand, Kuhn was one of the most influential and important philosophers of science in the second half of the twentieth century. On the other hand, nowadays there is little distinctively Kuhn’s legacy in the sense that most of Kuhn’s work has no longer any philosophical significance. Bird argues that the explanation of the paradox of Kuhn’s legacy is that (...) Kuhn took a direction opposite to that of the mainstream of the philosophy of science in his later academic career. This paper aims to provide a new way to understand and develop Kuhn’s legacy by revisiting the development of Kuhn’s philosophy of science in 1970s and proposing a new account of exemplar. Firstly, I propose my diagnosis of Kuhn’s “wrong turning” by identifying Kuhn’s two novel contributions: the introduction of paradigm and the proposal of the incommensurability thesis. Secondly, I argue that Kuhn made a conceptual/terminological turn from paradigm to theory, which undermined Kuhn’s novel contributions. Thirdly, I propose a new articulation of exemplar and propose an exemplar-based approach to analysing the history of science. Finally, I show how the exemplar-based approach can be applied to analyse the history of science by my case study of the early development of genetics. (shrink)

Evidential Pluralism maintains that in order to establish a causal claim one normally needs to establish the existence of an appropriate conditional correlation and the existence of an appropriate mechanism complex, so when assessing a causal claim one ought to consider both association studies and mechanistic studies. Hitherto, Evidential Pluralism has been applied to medicine, leading to the EBM+ programme, which recommends that evidence-based medicine should systematically evaluate mechanistic studies alongside clinical studies. This paper argues that Evidential Pluralism can also (...) be fruitfully applied to the social sciences. In particular, Evidential Pluralism provides (i) a new approach to evidence-based policy; (ii) an account of the evidential relationships in more theoretical research; and (iii) new philosophical motivation for mixed methods research. The application of Evidential Pluralism to the social sciences is also defended against two objections. (shrink)

The paper discusses five conceptions of knowledge present in texts traditionally associated with the thought of such thinkers as Kongzi, Mozi, Mengzi, Xunzi, Laozi, Zhuangzi, and Hanfeizi. The first three maps onto conceptions of knowledge familiar to contemporary ears: skill knowledge (knowing-how), propositional knowledge (knowing-that) and objectual knowledge (knowing by acquaintance); while the next two map onto less commonly discussed conceptions of knowledge: motivational knowledge (knowing-to) and applied knowledge (knowing-how-to). The discussion aims to complement existing projects in the literature that (...) look at related issues more explicitly from the standpoint of the ‘native’ concepts. The paper concludes with some comments on the early Chinese philosophical concerns with knowledge and its relation to broader conceptions of ‘philosophical’ projects. (shrink)

The epistemic theory of causality views causality as a tool that helps us to predict, explain and control our world, rather than as a relation that exists independently of our epistemic practices. In this chapter, we first provide an introduction to the epistemic theory of causality. We then outline four considerations that motivate the epistemic theory: the failure of standard theories of causality; parsimony; the epistemology of causality; and neutrality. We illustrate these four considerations in the contexts of the social (...) sciences and the cognitive sciences. We argue that the epistemic theory provides a very natural account of causality across these contexts. (shrink)

Historiographical analyses of the development of genetics in the first decade of the 20th century have been to a great extent framed in the context of the Mendelian-Biometrician controversy. Much has been discussed on the nature, origin, development, and legacy of the controversy. However, such a framework is becoming less useful and fruitful. This paper challenges the traditional historiography framed by the Mendelian-Biometrician distinction. It argues that the Mendelian-Biometrician distinction fails to reflect the theoretical and methodological diversity in the controversy. (...) It also argues that that the Mendelian-Biometrician distinction is not helpful to make a full understanding of the development of genetics in the first decade of the twentieth century. (shrink)

This paper provides a critical review of the debate over the philosophical foundations of mixed methods research and examines the notion of philosophical foundations. It distinguishes axiology-oriented from ontology-oriented philosophical foundations. It also identifies three different senses of philosophical foundations of mixed methods research. The weak sense of philosophical foundations (e.g., pragmatism) merely allows the possibility of the integration of both quantitative and qualitative methods/data/designs. The moderate sense of philosophical foundations (e.g., transformativism) provide a good reason to use mixed methods (...) in (at least some) social scientific research. The strong sense of philosophical foundations (e.g., dialectical pluralism) justifies a normative thesis that mixed methods research should be encouraged in (at least some) social scientific research.

We show that the physical meaning of the wave function can be derived based on the established parts of quantum mechanics. It turns out that the wave function represents the state of random discontinuous motion of particles, and its modulus square determines the probability density of the particles appearing in certain positions in space.

We introduce an expected-value theory of linguistic modality that makes reference to expected utility and a likelihood-based confirmation measure for deontics and epistemics, respectively. The account is a probabilistic semantics for deontics and epistemics, yet it proposes that deontics and epistemics share a common core modal semantics, as in traditional possible-worlds analysis of modality. We argue that this account is not only theoretically advantageous, but also has far-reaching empirical consequences. In particular, we predict modal versions of reasoning fallacies from the (...) heuristics and biases literature. Additionally, we derive the modal semantics in an entirely transparent manner, as it is based on the compositional semantics of Korean modal expressions that are morphosyntactically decomposed into a conditional and an evaluative predicate.

The nature of scientific explanation is controversial. Some maintain that all scientific explanations have to be contrastive in nature (contrastivism). However, others argue that no scientific explanation is genuinely contrastive (non-contrastivism). In addition, a compatibilist view has been recently devloped. It is argued that the debate between contrastivism and non-contrastivism is merely a linguistic dispute rather than a genuine disagreement on the nature of scientific explanation. Scientific explanations are both contrastive and non-contrastive in some sense (compatibilism). This paper examines the (...) debate between contrastivism and non-contrastivism in scientific explanation. It begins with a critical review of the arguments for contrastivism, for non-contrastivism, and for compatibilism and concludes with some remarks on the prospect of the issue. (shrink)

In Book 1 of Plato’s Republic, Thrasymachus contends two major claims: (1) justice is the advantage of the stronger, and (2) justice is the good of the other, while injustice is to one’s own profit and advantage. In the beginning of Book II, Glaucon self-proclaims that he will be representing Thrasymachus’ claims in a better way, and provides a story of how justice has originated from a state of nature situation. However, Glaucon’s story of the origin of justice has an (...) implication that justice is the advantage of the weak rather than the stronger. This is inconsistent with Thrasymachus’ first claim which states that justice is the advantage of the stronger. This is a problem for Glaucon since Glaucon is supposed to be representing Thrasymachus’ original claims in a better way. In this paper, I provide two solutions to this puzzle with the help of elementary game theory. (shrink)

One of the interpretive devices that Ch'eng-kuan (澄 觀) is famous for having employed to distill the essence of the vast Mahāvaipulya Buddhāvataṃsaka Sūtra (Tafang-kuang fo-hua-yen ching 《大方廣佛華嚴經》 was a series of variations on the contemplative theme (kuan-men 觀門) of the complete interfusion (yüan-jung 圓融) of the scripture's three chief protagonists (san-sheng 三聖) ── the Buddha Vairocana (Pi-lu-che-na 毘盧遮那) and the bodhisattvas Mañjuśrī (Wen-shu-shih-li 文殊師利) and Samantabhadra (P'u-hsien 普賢). By aligning these three powerful sacred persons with a number of philosophical (...) categories that he believed to be central to the sūtra ── categories like "cause" (yin 因 ), "fruition" (kuo 果 ), "faith" (hsin 信 ), "understanding" (chieh 解), "insight" (chih 智), "practice" (hsing 行), "principle" (li 理), etc. ── he provided a focal point at which the rich and vivid meditative and liturgical lives of Hua-yen devotees could be made to converge with their philosophical reflections. -/- Although Ch'eng-kuan invoked this device in several of his writings, his most concerted development of it is a short essay entitled San-sheng yüan-jung kuan-men, which appears to have been written relatively late in his long career. Like many important Hua-yen texts, this essay seems to have been lost in China not long after its author's death. However, it was preserved in Korea and Japan and from the latter country was reintroduced to China in the last years of nineteenth century. Neither in China nor in the West has it yet been adequately studied. -/- The core of the present article is a critical edition of the Chinese text of the essay based on a careful comparison of all available versions and presented together with a copiously annotated English translation. The edition translation are preceded by a brief interpretive introduction and followed by an appendix in which are given: a detailed discussion of the work's textual history, detailed accounts of its various editions, and descriptions of its several surviving paraphrases and commentaries.

Among biologists and philosophers, there is an ongoing debate over the Modern Synthesis and the Extended Evolutionary Synthesis. Some argue that our current evolutionary biology is in need of (at least) some substantial revision or nontrivial extension, while others maintain that the Modern Synthesis remains the foundational framework for evolutionary biology. It has been widely debated whether the Extended Evolutionary Synthesis provides a more promising framework than the Modern Synthesis. The nature and methodological implications of the Extended Evolutionary Synthesis were (...) also examined. This paper offers an integrated historical and philosophical examination of the debate over the Extended Evolutionary Synthesis. It reviews the development of evolutionary biology of the twentieth century. It argues that there are substantial conceptual and theoretical differences between the Modern Synthesis and the Extended Evolutionary Synthesis, but they are not incommensurable paradigms in the Kuhnian sense. It also argues for a functional approach to the debate over these two frameworks of evolutionary theory. (shrink)

It also discusses the concept of causation in cognitive science and the implications of (...) evidential diversity for the social sciences. (shrink)

Despite his enormous influence on the philosophy of science, Kuhn seems to have been unfairly treated by philosophers. His work was often oversimplified, misinterpreted, and quickly dismissed. The legacy of Kuhn for contemporary philosophy of science seems to be unfortunately thin.

It explores Kuhnian or neo-Kuhnian approaches to central issues in twenty-first philosophy of science. It also rereads (...)

Based on an analysis of protective measurements, we show that the quantum state represents the physical state of a single quantum system. This result is more definite than the PBR theorem [Pusey, Barrett, and Rudolph, Nature Phys. 8, 475 (2012)].

We analyze the possible implications of spacetime discreteness for the special and general relativity and quantum theory. It is argued that the existence of a minimum size of spacetime may explain the invariance of the speed of light in special relativity and Einstein’s equivalence principle in general relativity. Moreover, the discreteness of spacetime may also result in the collapse of the wave function in quantum mechanics, which may provide a possible solution to the quantum measurement problem. These interesting results might (...) have some important implications for a complete theory of quantum gravity. (shrink)

With the rising poverty in the Philippines, Filipino farm workers in Agusan del Sur faced distinctive challenges in their homes and working environment. This study aimed to discuss Filipino farm workers’ lived experiences, challenges, and coping mechanisms. Filipino farm workers shared their experiences that tapped into their psychological aspects. Mainly, the problem was stress, worry, and frustration centered on poverty and educational attainment. Some farm workers were likely unaware of the main problem that prolonged their hardships. Still, most have managed (...) to fortify their mental health. This report indicates that most Filipino farm workers in Agusan del Sur have a healthy psychological well-being. However, this statement does not change the intensity of their struggle to survive. (shrink)

The notion of intentionality has been in the center of the debate between dualism and physicalism quite some time. Dualism insists that intentionality is the mark of mental phenomena which separates humans from other animals whereas physicalism roughly claims that whatever there is either reducible to some physical states or explainable in terms of some physical language. But both of them are deeply troubled. Is there any other alternative? Where can we look for one? We know that Asian tradition is (...) full of organic world views. I am inclined to think that one alternative world view may come from this background. This paper tries to show that the notion of cheng(誠) intentionality is such a candidate. -/- I will advance a thesis in this paper that cheng(誠) intentionality is holistic. The notion is not only applicable to humans but also to all other phenomena. This may seem indistinguishable from physicalism in its monistic settings. Since I believe that the notion of cheng(誠) is more persuasive in explaining mental phenomena in evolutionary terms, I would argue here that the thesis can also be supported by some notions like that an information is a syntactical structure which reflects physical states and that the physicalisitic view of the world is not sufficient.

Philosophical analyses of causation have been centred on the question of what causation is. More precisely speaking, philosophers tend to address four different issues: metaphysical (what is causation out there?), epistemological (how can a causal claim be established and assessed?), conceptual (what does the word ‘cause’ mean?), and methodological (what methods ought one to use in order to establish and assess causal claims?). This chapter argues that the practical issue of causation (what is a causal claim for in practice?) is (...) highly relevant to the metaphysical, epistemological, conceptual, and methodological issues of causation. Any philosophical enquiry into causation without an examination of this practical issue is incomplete. In other words, a promising approach to causation ought to take all of the metaphysical, epistemological, conceptual, methodological, and practical issues into account. (shrink)

Scientific progress is a hot topic in the philosophy of science. However, as yet we lack a comprehensive philosophical examination of scientific progress. First, the recent debate pays too much attention to the epistemic approach and the semantic approach. Shan’s new functional approach and Dellsén’s noetic approach are still insufficiently assessed. Second, there is little in-depth analysis of the progress in the history of the sciences. Third, many related philosophical issues are still to be explored. For example, what are (...) the implications of scientific progress for the scientific realism/antirealism debate? Is the incommensurability thesis a challenge to scientific progress? What role does aesthetic values play in scientific progress? Does idealisation impede scientific progress? This book fills this gap. It offers a new assessment of the four main approaches to scientific progress (Part I). It also features eight historical case studies to investigate the notion of progress in different disciplines: physics, chemistry, evolutionary biology, seismology, psychology, sociology, economics, and medicine respectively (Part II). It discusses some issues related to scientific progress: scientific realism, incommensurability, values in science, idealisation, scientific speculation, interdisciplinarity, and scientific perspectivalism (Part III).

A variety of philosophical positions have been proposed and developed to motivate, justify, and guide mixed methods research. This chapter provides a brief overview of the main positions in the debate over the philosophical foundations of mixed methods research. It shows that ‘philosophical foundations’ means differently while different positions provide ‘philosophical foundations’ in different senses. It also highlights the significance of the collaboration between researchers and philosophers in the examination of the philosophical foundations of mixed methods research.

The Seed Thoughts proposed by YU Youngmo and HAM Sukhun may each be summed up by propositions expressed in “People are a May-fly seed” and “Seeds embody the eternal meaning”. They used “seed” to refer to humans or people on the one hand and placed the notion of seed in the holistic context of the Eastern Asian tradition on the other. Then, I seek to connect the anthropological notion and the holistic notion via cheng(誠) or integration. 『The Doctrine of the (...) Mean』says that any ultimate integration(至誠) reflects the total nature of objects involved(盡性) by showing that self realization and all other realizations are one and not two(成己成物) and by arriving at the stage of holiness (聖). Then, I may be allowed to say that cheng is a mind or a power not only of humans but also of all other things. Important elements of cheng intentionality can be read out of the two thinker’s various conceptual aspects. YU’s interpretation of history to be internalistic, his view of Hangul(Korean written language) as a revealational medium, his hermeneutics of Christian God as the Vacuum cannot be understood on the dichotomous model of human-nature. HAM’s seed holism, his beliefs that humans’s minds are the heavenly mind and that all things under the heaven should come to be unified are best to be understood on the model of cheng intentionality of integration.

As physicalisms of various kinds have faced difficulties in recent years, the time has come to explore possible alternatives, one of which is yinyang ontology. A yinyang theorist is expected to provide a plausible account of causation to replace the traditional notion of causation. The present paper is critical of the Humean tradition, which understands the relata of causal relations in terms of passive materiality so that humans use referential terms to describe causal relations constructively. But an alternative notion of (...) reference is available according to which causal relata are active processors of the information with which they interact. On this latter view, humans use referential language to describe the structure in which the relata interrelate themselves so that the structure can be understood hermeneutically. Reference on this view is naturalized. In this article I advance two arguments for this thesis, one concerning the informationality of states and the other related to the essentiality of properties.

According to the laws of physics, the state of a physical system can only be measured by another system (usually a particular measuring device) via a physical interaction. However, when our brain is in a conscious mental state, it can in principle output the information about its physical state based on the psycho-physical correspondance between the mental state and the physical state. It is argued that this suggests that the conscious mind violates physical laws and it is not physical as (...) physicalism claims. (shrink)

We investigate the meaning of the wave function by analyzing the mass and charge density distributions of a quantum system. According to protective measurement, a charged quantum system has effective mass and charge density distributing in space, proportional to the square of the absolute value of its wave function. In a realistic interpretation, the wave function of a quantum system can be taken as a description of either a physical field or the ergodic motion of a particle. The essential difference (...) between a field and the ergodic motion of a particle lies in the property of simultaneity; a field exists throughout space simultaneously, whereas the ergodic motion of a particle exists throughout space in a time-divided way. If the wave function is a physical field, then the mass and charge density will be distributed in space simultaneously for a charged quantum system, and thus there will exist gravitational and electrostatic self-interactions of its wave function. This not only violates the superposition principle of quantum mechanics but also contradicts experimental observations. Thus the wave function cannot be a description of a physical field but a description of the ergodic motion of a particle. For the later there is only a localized particle with mass and charge at every instant, and thus there will not exist any self-interaction for the wave function. Which kind of ergodic motion of particles then? It is argued that the classical ergodic models, which assume continuous motion of particles, cannot be consistent with quantum mechanics. Based on the negative result, we suggest that the wave function is a description of the quantum motion of particles, which is random and discontinuous in nature. On this interpretation, the square of the absolute value of the wave function not only gives the probability of the particle being found in certain locations, but also gives the probability of the particle being there. We show that this new interpretation of the wave function provides a natural realistic alternative to the orthodox interpretation, and its implications for other realistic interpretations of quantum mechanics are also briefly discussed.

Scientific revolution has been one of the most controversial topics in the history and philosophy of science. Yet it has been no consensus on what is the best unit of analysis in the historiography of scientific revolutions. Nor is there a consensus on what best explains the nature of scientific revolutions. This chapter provides a critical examination of the historiography of scientific revolutions. It begins with a brief introduction to the historical development of the concept of scientific revolution, followed by (...) an overview of the five main philosophical accounts of scientific revolutions. It then challenges two historiographical assumptions of the philosophical analyses of scientific revolutions. (shrink)

It seems that a new notion of language played an important role in seeing how notions like knowledge and humanities are to be understood anew. I believe that our notion of language is not only pluralistic in the sense that distinct verbal languages force us to see the world in different ways but also ubiquitous in the sense that anything which is seen by human eyes or which is processed digitally is a text in need of interpretation. Then, our notion (...) of knowledge needs to be communal rather than absolutistic and the ideal of the contemporary human predicament is such that we may go beyond its passive freedom to a more active freedom. These two conditions appear to suggest a bridge by which one can relate the humanities in the academic world and the humanities in the cultural markets. (shrink)

Bird’s new book, Knowing Science, provides an exemplar of how to do epistemology and philosophy of science together. While I wholeheartedly appreciate his attempt to bridge the gap between epistemology and philosophy of science and find his project promising, I am not convinced by the central thesis of the book that knowledge plays a central role in science. In this article, I focus on Bird’s epistemic account of scientific progress, which is the view that the nature of scientific progress is (...) the accumulation of scientific knowledge. Contra Bird, I argue that scientific progress cannot be fully characterised as the accumulation of scientific knowledge. (shrink)

We give a new argument supporting a gravitational role in quantum collapse. It is demonstrated that the discreteness of space-time, which results from the proper combination of quantum theory and general relativity, may inevitably result in the dynamical collapse of thewave function. Moreover, the minimum size of discrete space-time yields a plausible collapse criterion consistent with experiments. By assuming that the source to collapse the wave function is the inherent random motion of particles described by the wave function, we further (...) propose a concrete model of wavefunction collapse in the discrete space-time. It is shown that the model is consistent with the existing experiments and macroscopic experiences. (shrink)

Recently there has been an increasing interest in metaphilosphy. The aim of philosophy has been examined. The development of philosophy has also been scrutinised. With the development of new approaches and methods, new problems arise. This collection revisits some of the metaphilosophical issues, including philosophical progress and the aim of philosophy. It sheds new light on some old approaches, such as naturalism and ordinary language philosophy. It also explores new philosophical methods (e.g., digital philosophy of science, conceptual engineering, and the (...) practice-based approach to logic) and their prospects. (shrink)

For a while, life and environment have been regarded as two separate subjects, but recently life and environment are to be seen as different aspects of one single theme. There are able philosophers who maintain the connection of the two but Seokheon Ham is believed to present a more coherent case. To him, integration is not merely a property which is unifying various elements, but it has a deep ontological structure seen in his utterance “there is not a thing in (...) the world which does not have a reason to exist”. He is providing a model of deep integration by equivalently linking life and sense. And he offers apparent arguments of oneness as integration of animates and inanimates, seeds as an example of integration of sense and life, and suffering as a historical integration. But Ham’s arguments will be strengthened by philosophizing the notion of integration. Fortunately, I would suggest that the clue is found in the conception of integration of Zhungyong. I will take the major thrust of the book to be five theses: (1) integration of a thing is the capacity to realize its embedded objective in its interactions with all other things; (2) ‘mind’ denotes the capacity of humans as well as the capacity of all other entities: (3) integration is a capacity not only of humans but also of all other entities; (4) if the evolution demonstrates the history of species as the fittest, then the history expresses the evolution of life forms of intelligence and justice; (5) integration of an entity is a disposition to realize its embedded objective in the context of its interconnections with all others at a particular time and place. The ontology of integration I am submitting may be shown to be an alternative to traditional physicalism. The integrational ontology may be seen as virtuous in that it is coherent with the informational view of the contemporary culture and with the caring need for those who suffer. (shrink)

Thomas Kuhn (1922-1996) is widely considered as one of the most important philosophers of science of the 20th century, while his The Structure of Scientific Revolutions (SSR) is regarded as one of the most influential works in the philosophy ofscience. At the same time, however, his place within philosophy of science remains ambiguous. On the one hand, despite the popularity of SSR, there is no proper ‘Kuhnian school of thought’ in HPS. On the other hand, the interest towards Kuhn does (...) not seem to fade away and the number of publications about his work does not seem to decrease. We suggest that there are at least three different ways to go ‘beyond SSR’: (i) by scrutinising the development of Kuhn’s thought, from his pre- to his post-SSR writings; (ii) by contextualising Kuhn in the philosophical milieu of his time, thus interpreting his view as emerging from the intellectual exchanges he had with contemporary philosophers; (iii) by reinterpreting and developing some of his most known ideas, in ways that perhaps Kuhn himself was not able to contemplate.

It is shown that the heuristic "derivation" of the Schrödinger equation in quantum mechanics textbooks can be turned into a real derivation by resorting to spacetime translation invariance and relativistic invariance.

In his 2012 book On Global Justice, Mathias Risse makes an invaluable contribution to the literature on theories of global justice. In this paper, I offer a critique of the fourth and final part of the book, entitled “Global Justice and Institutions,” which deals with the standing of the state within the pluralist internationalism defended by the author. My focus here is on the justification of the state system and the discussion on utopian ideals. I agree with Risse that the (...) state remains the inescapable political structure that any serious theory of global justice must internalize within its conceptual framework. However, I differ from Risse’s approach in that I place greater emphasis on the historical contingency of the state system, including how prescriptions of global justice reflect historical contingencies stemming from globalization. From this point of view, pluralist internationalism should then be understood as a conceptual paradigm that mirrors its own historical contingency as embedded in our current world order. This recognition of the historical contingency of the state system serves two important purposes. One, it is a bulwark against any tendency to discredit too quickly the philosophical and practical relevance of ideal theory. Two, it buttresses the stance that we might still have the moral duty to pursue the goal of global justice beyond pluralist internationalism. (shrink)

We investigate the validity of the field explanation of the wave function by analyzing the mass and charge density distributions of a quantum system. It is argued that a charged quantum system has effective mass and charge density distributing in space, proportional to the square of the absolute value of its wave function. This is also a consequence of protective measurement. If the wave function is a physical field, then the mass and charge density will be distributed in space simultaneously (...) for a charged quantum system, and thus there will exist a remarkable electrostatic self-interaction of its wave function, though the gravitational self-interaction is too weak to be detected presently. This not only violates the superposition principle of quantum mechanics but also contradicts experimental observations. Thus we conclude that the wave function cannot be a description of a physical field. In the second part of this paper, we further analyze the implications of these results for the main realistic interpretations of quantum mechanics, especially for de Broglie-Bohm theory. It has been argued that de Broglie-Bohm theory gives the same predictions as quantum mechanics by means of quantum equilibrium hypothesis. However, this equivalence is based on the premise that the wave function, regarded as a Ψ-field, has no mass and charge density distributions, which turns out to be wrong according to the above results. For a charged quantum system, both Ψ-field and Bohmian particle have charge density distribution. This then results in the existence of an electrostatic self-interaction of the field and an electromagnetic interaction between the field and Bohmian particle, which contradicts both the predictions of quantum mechanics and experimental observations. Therefore, de Broglie-Bohm theory as a realistic interpretation of quantum mechanics is probably wrong. Lastly, we suggest that the wave function is a description of some sort of ergodic motion (e.g. random discontinuous motion) of particles, and we also briefly analyze the implications of this suggestion for other realistic interpretations of quantum mechanics including many-worlds interpretation and dynamical collapse theories.

The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force. In this paper, we will argue that the idea of gravity as an entropic force is debatable. It is shown that there is no convincing analogy between gravity and entropic force in Verlinde’s example. Neither holographic screen nor test particle satisfies all requirements for the existence of entropic force in a thermodynamics (...) system. As a result, there is no entropic force in the gravity system. Furthermore, we show that the entropy increase of the screen is not caused by its statistical tendency to increase entropy as required by the existence of entropic force, but in fact caused by gravity. Therefore, Verlinde’s argument for the entropic origin of gravity is problematic. In addition, we argue that the existence of a minimum size of spacetime, together with the Heisenberg uncertainty principle in quantum theory, may imply the fundamental existence of gravity as a geometric property of spacetime. This provides a further support for the conclusion that gravity is not an entropic force. (shrink)

The meaning of the wave function and its evolution are investigated. First, we argue that the wave function in quantum mechanics is a description of random discontinuous motion of particles, and the modulus square of the wave function gives the probability density of the particles being in certain locations in space. Next, we show that the linear non-relativistic evolution of the wave function of an isolated system obeys the free Schrödinger equation due to the requirements of spacetime translation invariance and (...) relativistic invariance. Thirdly, we argue that the random discontinuous motion of particles may lead to a stochastic, nonlinear collapse evolution of the wave function. A discrete model of energy-conserved wavefunction collapse is proposed and shown consistent with existing experiments and our macroscopic experience. Besides, we also give a critical analysis of the de Broglie-Bohm theory, the many-worlds interpretation and other dynamical collapse theories, and briefly discuss the issues of unifying quantum mechanics and relativity. (shrink)

We investigate the implications of protective measurement for de Broglie-Bohm theory, mainly focusing on the interpretation of the wave function. It has been argued that the de Broglie-Bohm theory gives the same predictions as quantum mechanics by means of quantum equilibrium hypothesis. However, this equivalence is based on the premise that the wave function, regarded as a Ψ-field, has no mass and charge density distributions. But this premise turns out to be wrong according to protective measurement; a charged quantum system (...) has effective mass and charge density distributing in space, proportional to the square of the absolute value of its wave function. Then in the de Broglie-Bohm theory both Ψ-field and Bohmian particle will have charge density distribution for a charged quantum system. This will result in the existence of an electrostatic self-interaction of the field and an electromagnetic interaction between the field and Bohmian particle, which not only violates the superposition principle of quantum mechanics but also contradicts experimental observations. Therefore, the de Broglie-Bohm theory as a realistic interpretation of quantum mechanics is problematic according to protective measurement. Lastly, we briefly discuss the possibility that the wave function is not a physical field but a description of some sort of ergodic motion (e.g. random discontinuous motion) of particles. (shrink)

It is shown that the superposed wave function of a measuring device, in each branch of which there is a definite measurement result, does not correspond to many mutually unobservable but equally real worlds, as the superposed wave function can be observed in our world by protective measurement.

In quantum mechanics, the wave function of a N-body system is a mathematical function defined in a 3N-dimensional configuration space. We argue that wave function realism implies particle ontology when assuming: (1) the wave function of a N-body system describes N physical entities; (2) each triple of the 3N coordinates of a point in configuration space that relates to one physical entity represents a point in ordinary three-dimensional space. Moreover, the motion of particles is random and discontinuous.

A well-ordered society faces a crisis whenever a sufficient number of noncompliers enter into the political system. This has the potential to destabilize liberal democratic political order. This article provides a formal analysis of two competing solutions to the problem of political stability offered in the public reason liberalism literature—namely, using public reason or using convergence discourse to restore liberal democratic political order in the well-ordered society. The formal analyses offered in this article show that using public reason fails completely, (...) and using convergent discourse, although doing better, has its own critical limitations that have not been previously recognized properly.

Inspired by impossibility theorems of social choice theory, many democratic theorists have argued that aggregative forms of democracy cannot lend full democratic justification for the collective decisions reached. Hence, democratic theorists have turned their attention to deliberative democracy, according to which “outcomes are democratically legitimate if and only if they could be the object of a free and reasoned agreement among equals” (Cohen 1997a, 73). However, relatively little work has been done to offer a formal theory of democratic deliberation. This (...) article helps fill that gap by offering a formal theory of three different modes of democratic deliberation: myopic discussion, constructive discussion, and debate. We show that myopic discussion suffers from indeterminacy of long run outcomes, while constructive discussion and debate are conclusive. Finally, unlike the other two modes of deliberation, debate is path independent and converges to a unique compromise position, irrespective of the initial status quo. (shrink)

The paper explores the influence of greenwash on green trust and discusses the mediation roles of green consumer confusion and green perceived risk. The research object of this study focuses on Taiwanese consumers who have the purchase experience of information and electronics products in Taiwan. This research employs an empirical study by means of the structural equation modeling. The results show that greenwash is negatively related to green trust. Therefore, this study suggests that companies must reduce their greenwash behaviors to (...) enhance their consumers’ green trust. In addition, this study finds out that green consumer confusion and green perceived risk mediate the negative relationship between greenwash and green trust. The results also demonstrate that greenwash is positively associated with green consumer confusion and green perceived risk which would negatively affect green trust. It means that greenwash does not only negatively affect green trust directly but also negatively influence it via green consumer confusion and green perceived risk indirectly. Hence, if companies would like to reduce the negative relationship between greenwash and green trust, they need to decrease their consumers’ green consumer confusion and green perceived risk.

It seems that a new notion of language played an important role in seeing how notions like knowledge and humanities are to be understood anew. I believe that our notion of language is not only pluralistic in the sense that distinct verbal languages force us to see the world in different ways but also ubiquitous in the sense that anything which is seen by human eyes or which is processed digitally is a text in need of interpretation. Then, our notion (...) of knowledge needs to be communal rather than absolutistic and the ideal of the contemporary human predicament is such that we may go beyond its passive freedom to a more active freedom. These two conditions appear to suggest a bridge by which one can relate the humanities in the academic world and the humanities in the cultural markets. (shrink)
