Especially over the past twenty years, a number of analytic philosophers have embraced the idea that the world itself is vague or indeterminate in one or more respects. The issue then arises as to whether it can be the case that the world itself is indeterminate in all respects. Using as a basis Chinese Madhyamaka Buddhist thought, I offer two reasons for the coherence and intelligibility of the thesis that all concrete things are themselves indeterminate with respect to the ways (...) they are. The first reason draws on a notion reminiscent of the picture of reality as an amorphous lump, while the second reason makes use of the relativity of conceptual perspectives and determinations. Assuming that the world is the mere totality of all concrete things, I show that there is a genuine metaphysical possibility of the world’s being indeterminate in all respects. (shrink)

A number of analytical philosophers have recently endorsed the view that the world itself is indeterminate in some respect. Intriguingly, ideas similar to the view are expressed by thinkers from Chinese Madhyamaka Buddhism, which may shed light on the current discussion of worldly indeterminacy. Using as a basis Chinese Madhyamaka thought, together with Jessica Wilson’s account of indeterminacy, I develop an ontological conception of indeterminacy, termed ontic indeterminacy, which centres on two complementary ideas—conclusive indeterminability and provisional determinability. I show that (...) OI is well-equipped to tackle several issues of worldly indeterminacy. My overarching aim is to present a viable and sustainable perspective on the subject of indeterminacy to enrich analytical philosophers’ insights into the intricate nature of reality. (shrink)

This essay attempts to provide a systematic reconstruction of Nāgārjuna's philosophical thought by understanding it as a critique of the attachment to linguistic expressions and their referents. We first present an outline of Nāgārjuna's philosophy, centering on such notions as 'dependent origination', 'emptiness' and 'self-nature'. Then we discuss Nāgārjuna's dismissal of a metaphysical use of language, particularly his contention that language can function well without assuming the reality of its referents. We also consider his statement that he has no assertion (...) and explain his provisional use of language. Towards the end of the essay, we direct our attention to a paradoxical formula in a Buddhist sutra that should help in evaluating the contemporary significance of Nāgārjuna's linguistic critique.

Theorists who advocate worldly (metaphysical or ontological) indeterminacy—the idea that the world itself is indeterminate in one or more respects—should address how we understand the signifying nature and function of language in light of worldly indeterminacy. I first attend to Sengzhao and Jizang, two leading thinkers in Chinese Sanlun Buddhism, to reconstruct a Chinese Madhyamaka notion of ontic indeterminacy. Then, I draw on the thinkers’ views to propose a provisional (non-definitive) understanding of the nature and use of language. Under this (...) understanding, an expression signifying a thing is provisional in that the expression connotes no determinate feature of the thing. (shrink)

In his essay “Things Do Not Move,” Sengzhao (374?−414 CE), a prominent Chinese Buddhist philosopher, argues for the thesis that the myriad things do not move in time. This view is counter-intuitive and seems to run counter to the Mahayana Buddhist doctrine of emptiness. In this book chapter, I assess Sengzhao’s arguments for his thesis, elucidate his stance on the change/nonchange of things, and discuss related problems. I argue that although Sengzhao is keen on showing the plausibility of the thesis, (...) he actually views the myriad things as both changing and unchanging and upholds the nonduality of motion and rest. In fact, the nonmoving thesis follows from the discernment that things change from moment to moment without there being any enduring stuff in the process. Among philosophical works that confer a higher ontological status on nonchange over change, Sengzhao’s essay is unique and well worth pondering. (shrink)

A number of traditional philosophers and religious thinkers advocated an ineffability thesis to the effect that the ultimate reality cannot be expressed as it truly is by human concepts and words. However, if X is ineffable, the question arises as to how words can be used to gesture toward it. We can't even say that X is unsayable, because in doing so, we would have made it sayable. In this article, I examine the solution offered by the fifth-century Indian grammarian-philosopher (...) Bhartrhari and develop it into a linguistic strategy based on the imposition-cum-negation method. The purpose is to show how we can non-contradictorily say, or rather indicate, the unsayable. (shrink)

In this essay I attempt a philosophical analysis of the Chinese Buddhist thought of linguistic reference to shed light on how the Buddhist understands the way language refers to an ineffable reality. For this purpose, the essay proceeds in two directions: an enquiry into the linguistic thoughts of Sengzhao (374-414 CE) and Jizang (549-623 CE), two leading Chinese Madhyamika thinkers, and an analysis of the Buddhist simile of a moon-pointing finger. The two approaches respectively constitute the horizontal and vertical axes (...) of this essay. The simile of a moon-pointing finger originated in Indian Buddhism and later received much attention in Chinese Buddhism. In light of the Chinese Buddhist interpretations of the simile, I set forth six theses to make explicit the philosophic implications there involved. They are: (1) words in no way correspond with the ineffable Real and cannot say or properly express the Real; (2) words can point toward the Real by means of the forms meant or properly expressed by them; (3) the forms are plainly different from the Real and so are to be negated; (4) one who takes the forms for the Real not only misunderstands the Real but is also ignorant of the function of language; (5) the forgetting of words and their forms can dissolve the entanglement of language and thought and even lead to the intuition of the Real; (6) the intuition of the Real depends upon extra-linguistic factors as well as language. In elaborating the theses, I resort to passages in Sengzhao’s and Jizang’s works to disclose their linguistic thoughts in relation to the theses. A main concern here is to show how one can speak the unspeakable, how one can refer to an ineffable reality without committing self-contradiction. This is done in relation to their views, the theses as well as a free interpretive analysis. I construe the notion of indication as involving the imposition-cum-negation method and argue that one can use words to indicate the ineffable without at the same time describing it. The ineffable is indescribable, but it can be intimated through indication. Meanwhile, I also discuss Zhuangzi’s notion of word-forgetting as it plays a role in the simile and in Jizang’s philosophy of language. One of the purposes of this essay is to show that while valuing the therapeutic and evocative functions of religious language, Chinese Buddhist thinkers also understand the language indicatively. Without taking note of the indicative function of religious language, one cannot form an adequate picture of the Chinese Buddhist -- especially, the Chinese Madhyamaka -- philosophy of language. (shrink)

A number of contemporary philosophers think that the unqualified statement “X is unspeakable” faces the danger of self-referential absurdity: if this statement is true, it must simultaneously be false, given that X is speakable by the predicate word “unspeakable.” This predicament is in this chapter formulated as an argument that I term the “ineffability paradox.” After examining the Buddhist semantic theory of apoha (exclusion) and an apoha solution to the issue, I resort to a few Chinese Buddhist and Hindu philosophical (...) materials to rationally reconstruct a strategy for resolving the paradox. By introducing the mode of expression termed “indication,” together with the relevant notions of superimposition and of gesturing beyond the horizon, I show that expressing the ineffable does not necessarily involve irresoluble contradiction. It is also suggested that philosophers may need to acknowledge the relevance of the notion of ineffability for contemporary philosophizing. (shrink)

For Sengzhao (374−414 CE), a leading Sanlun philosopher of Chinese Buddhism, things in the world are ontologically indeterminate in that they are devoid of any determinate form or nature. In his view, we should understand and use words provisionally, so that they are not taken to connote the determinacy of their referents. To echo the notion of ontic indeterminacy and indicate the provisionality of language, his main work, the Zhaolun, abounds in paradoxical expressions. In this essay, I offer a philosophical (...) analysis and rational reconstruction of Sengzhao’s linguistic thought, with a view to exploring the rationale for and purpose of his use of paradoxical language. (shrink)

In this paper I propose to inquire into the theory of self-awareness propounded by the two Buddhist epistemologists, Dignaga and Dharmakirti. I first give an outline of the Buddhist notion of consciousness, then deal with the notion of objectual appearance, and finally dwell on the theory itself together with certain arguments in its favor. It is shown that the Buddhists subscribed themselves to the following self-awareness thesis: that our waking consciousness is always pre-reflectively and nonconceptually aware of itself. Adopting an (...) approach of interpretive and comparative analysis, I also clarify significant differences between the theory and the correspondent Cartesian views in order to reveal the theory's contemporary relevancy. (shrink)

For Jizang (549−623), a prominent philosophical exponent of Chinese Madhyamaka, all things are empty of determinate form or nature. Given anything X, no linguistic item can truly and conclusively be applied to X in the sense of positing a determinate form or nature therein. This philosophy of ontic indeterminacy is connected closely with his notion of the Way (dao), which seems to indicate a kind of ineffable principle of reality. However, Jizang also equates the Way with nonacquisition as a conscious (...) state of freedom from any attachment and definite understanding whatsoever. The issue then becomes pressing as to how we are to understand Jizang's notion of the Way. Does it indicate some metaphysical principle or reality? Is it actually a skilful expedient to lead one to the consummate state of complete spiritual freedom? How is this issue related to Jizang's conception of ontic indeterminacy? In this book chapter, I examine Jizang's key writings in an attempt to clarify his ontological position. (shrink)

For Bhartrhari, a fifth-century Indian grammarian-philosopher, all conscious beings—beasts, birds and humans—are capable of what he called pratibha, a flash of indescribable intuitive understanding such that one knows what the present object “means” and what to do with it. Such an understanding, if correct, amounts to a mode of knowing that may best be termed knowing-what, to distinguish it from both knowing-that and knowing-how. This paper attempts to expound Bhartrhari’s conception of pratibha in relation to the notions of meaning, understanding, (...) and knowing. First, I touch briefly on Bhartrhari’s views of consciousness and language, and examine at some length his indescribability thesis concerning the intuitive meaning of a sentence. Then, I delineate the general features of pratibha as intuitive understanding and discuss its probable range in relation to expert intuition and sense perception. Thereafter, I relate pratibha to the notion of knowing-what and show why these two notions are to be differentiated from knowing-that and knowing-how. The paper concludes with some remarks on the contemporary relevance of Bhartrhari’s conception of pratibha. (shrink)

Chinese Chan or Zen Buddhism is renowned for its improvisational, atypical, and perplexing use of words. In particular, the tradition’s encounter dialogues, which took place between Chan masters and their interlocutors, abound in puzzling, astonishing, and paradoxical ways of speaking. In this chapter, we are concerned with Chan’s use of paradoxical language. In philosophical parlance, a linguistic paradox comprises the confluence of opposite or incongruent concepts in a way that runs counter to our common sense and ordinary rational thinking. One (...) naturally wonders about Chan masters’ rationales for their use of paradox. There are also concerns about whether the use violates the logical principle of noncontradiction to the effect that nothing can be both P and not-P all over in the same way at the same time. Chan became a viable Chinese Buddhist tradition during the Tang dynasty (618−907) and continued to develop for several centuries. The tradition had produced a huge literature; consequently, our investigation of its use of paradox cannot but be limited and selective. In the second section, I first sketch key ideas of Chan that are pertinent to our investigation and then examine the use of paradox in the sermons associated with certain Tang masters of the southern Chan. In the third section, I analyze the presence of paradoxical language in post-Tang encounter dialogues. The fourth section concludes. (shrink)

In this article, I first introduce an Indian Madhyamaka Buddhist critique of causality and discuss critically a contemporary Humean interpretation of the critique. After presenting a Chinese Madhyamaka interpretation, I resort to an ontological conception of indeterminacy, termed ontic indeterminacy, which draws on Chinese Madhyamaka thought together with Jessica Wilson’s account of metaphysical indeterminacy, to show that the conception is well equipped to unravel two puzzling issues that arise from the critique. I suggest that a world that consists of things (...) that are indeterminate with respect to certain ways they are is sufficient for it to embody causal phenomena. (shrink)

Although Chan, or Zen, Buddhism traditionally claimed itself as a special transmission outside doctrinal teachings that eschews the written word, it has long been praised for its improvisational, atypical, intriguing, and intricate use of words. Prominent Chan masters are characteristically skillful in employing paradoxical and aporetic phrases, figurative and poetic expressions, negations, questions, repetitions, and so forth, to express their thoughts, indicate their awakened states of mind, cut off the interlocutor’s habitual dualistic thinking, or evoke in him or her an (...) experience of awakening. This fact, among others, has led some contemporary scholars to claim that the Chan experience of awakening does not... (shrink)

Sengzhao (374?−414 CE), a leading Chinese Mādhyamika philosopher, holds that the myriad things are empty, and that they are, at bottom, the same as emptiness qua the way things truly are. In this paper, I distinguish the level of the myriad things from that of the way things truly are and call them, respectively, the ontic and the ontological levels. For Sengzhao, the myriad things at the ontic level are indeterminate and empty, and he equates the way things truly are (...) at the ontological level with emptiness. This paper explicates the ontic status of the myriad things and the ontological notion of emptiness and elucidates the relationship between them. I read Sengzhao as dismissing the idea that reality has a mind-independent structure that comprises discrete entities waiting to be captured by concepts. I show that his notion of emptiness points to a subject-object unity wherein both the subject and the myriad objects are conceptually undifferentiated. It will be seen that Sengzhao’s overall theory of emptiness is philosophically interesting in terms of its relevance for ontology and the relationship between language and reality. It provides a refreshing and challenging perspective on how we may perceive the world and understand our relationship to it. (shrink)

Mahayana Buddhist philosophers’ attitude toward language is notoriously negative. The transcendental reality is often said to be ineffable. One’s obsession to apprehend the truth through words is an intellectual disease to be cured Attachment to verbal and conceptual proliferation enslaves oneself in the afflictive circle of life and death. Nevertheless, no Buddhist can afford to overlook the significance of language in preaching Buddhist dharmas as well as in day-to-day transactions. The point is not that of keeping silence. Rather, one should (...) understand and use language in such a way that one alludes to the unsayable reality and somehow escapes the bewitchment of language. Perhaps with this realization in mind, Mahayana Buddhist metaphysicians had fostered the penchant for using, at the sentential level, denials, negations and paradoxes to couch their views. In a similar vein but mainly at the word level, Dignaga (ca. 480-540 CE) the Yogacara epistemologist’ offered us a theory of language known as apoha doctrine in his landmark work Pramiinasamuccaya (henceforth PS). It is the purpose of this article to construe the doctrine. (shrink)

In this essay, I investigate how Chinese Yogācāra scholars of the Tang dynasty explicated and supplemented the theory of apoha (exclusion) propounded by the Indian Buddhist epistemologist Dignāga, according to which a nominal word functions by excluding everything other than its own referent. I first present a brief exposition of the theory. Then, I show that although they had very limited access to Dignāga’s theory, Kuiji and Shentai provide constructive and significant explanations that supplement the theory. I also show that (...) the term zhequan has been construed in Chinese Buddhism in at least three different senses to mean: an expression that both excludes and signifies, an expression that merely excludes and does not signify, and a negative expression that merely excludes. The notion of apoha is related to the first two senses but not the third. (shrink)

Jizang sets forth a hermeneutical theory of “one name, infinite meanings” that proposes four types of interpretation of word meaning to the effect that a nominal word X means X, non-X, the negation of X, and all things whatsoever. In this article, I offer an analysis of the theory, with a view to elucidating Jizang's thought on meaning and reference and considering its contemporary significance. The theory, I argue, may best be viewed as an expedient means for telling us how (...) to use words provisionally without any definite understanding of their referents. (shrink)

Jizang (549−623 CE), the key philosophical exponent of the Sanlun tradition of Chinese Buddhism, based his philosophy considerably on his reading of the works of Nāgārjuna (c.150−250 CE), the founder of the Indian Madhyamaka school. However, although Jizang sought to follow Nāgārjuna closely, there are salient features in his thought on language that are notably absent from Nāgārjuna’s works. In this paper, I present a philosophical analysis of Jizang’s views of the relationship between speech and silence and compare them with (...) those of Nāgārjuna. I first elaborate on Nāgārjuna’s doctrine of twofold truth and discuss his thought concerning the relationship between language and ineffable quiescence. I then examine Jizang’s interpretation of the doctrine. Thereafter, I distinguish silence qua teaching from silence qua principle and examine Jizang’s views on the relationship between speech and these two kinds of silence. It is shown that while Nāgārjuna leans toward affirming a clear-cut distinction between speech and the ineffable quiescence, Jizang endorses the nonduality of conventional speech and sacred silence.

The signature of the formal language of mereology contains only one binary predicate P which stands for the relation “being a part of”. Traditionally, P must be a partial ordering, that is, ${\forall{x}Pxx, \forall{x}\forall{y}((Pxy\land Pyx)\to x=y)}$ and ${\forall{x}\forall{y}\forall{z}((Pxy\land Pyz)\to Pxz))}$ are three basic mereological axioms. The best-known mereological theory is “general extensional mereology”, which is axiomatized by the three basic axioms plus the following axiom and axiom schema: (Strong Supplementation) ${\forall{x}\forall{y}(\neg Pyx\to \exists z(Pzy\land \neg Ozx))}$ , where Oxy means ${\exists (...) z(Pzx\land Pzy)}$ , and (Fusion) ${\exists x\alpha \to \exists z\forall y(Oyz\leftrightarrow \exists x(\alpha \land Oyx))}$ , for any formula α where z and y do not occur free. In this paper, I will show that general extensional mereology is decidable, and will also point out that the decidability of the first-order approximation of the theory of complete Boolean algebras can be shown in the same way. (shrink)

Mereological theories are theories based on a binary predicate ‘being a part of’. It is believed that such a predicate must at least define a partial ordering. A mereological theory can be obtained by adding on top of the basic axioms of partial orderings some of the other axioms posited based on pertinent philosophical insights. Though mereological theories have aroused quite a few philosophers’ interest recently, not much has been said about their meta-logical properties. In this paper, I will look (...) into whether those theories are decidable or not. Besides, since theories of Boolean algebras are in some sense upper bounds of mereological theories which can be found in the literature, I shall also make some observations about the possibility of getting mereological theories beyond Boolean algebras. (shrink)

The signature of the formal language of mereology contains only one binary predicate which stands for the relation “being a part of” and it has been strongly suggested that such a predicate must at least define a partial ordering. Mereological theories owe their origin to Leśniewski. However, some more recent authors, such as Simons as well as Casati and Varzi, have reformulated mereology in a way most logicians today are familiar with. It turns out that any theory which can be (...) formed by using the reformulated mereological axioms or axiom schemas is in a sense a subtheory of the elementary theory of Boolean algebras or of the theory of infinite atomic Boolean algebras. It is known that the theory of partial orderings is undecidable while the elementary theory of Boolean algebras and the theory of infinite atomic Boolean algebras are decidable. In this paper, I will look into the behaviors in terms of decidability of those mereological theories located in between. More precisely, I will give a comprehensive picture of the said issue by offering solutions to the open problems which I have raised in some of my papers published previously. (shrink)

Quite a few results concerning the decidability of mereological theories have been given in my previous paper. But many mereological theories are still left unaccounted for. In this paper I will refine a general method for proving the undecidability of a theory and then by making use of it, I will show that most mereological theories that are strictly weaker than CEM are finitely inseparable and hence undecidable. The same results might be carried over to some extensions of those weak (...) theories by adding the fusion axiom schema. Most of the proofs to be presented in this paper take finite lattices as the base models when applying the refined method. However, I shall also point out the limitation of this kind of reduction and make some observations and conjectures concerning the decidability of stronger mereological theories. (shrink)

It is customary practice to define ‘x is composed of the ys’ as ‘x is a sum of the ys and the ys are pairwise disjoint ’. This predicate has played a central role in the debate on the special composition question and on related metaphysical issues concerning the mereological structure of objects. In this note we show that the customary characterization is nonetheless inadequate. We do so by constructing a mereological model where everything qualifies as composed of atoms even (...) though some elements in the domain are gunky, i.e., can be divided indefinitely into smaller and smaller proper parts. (shrink)

Mereology is the theory of the relation “being a part of”. The first exact formulation of mereology is due to the Polish logician Stanisław Leśniewski. But Leśniewski’s mereology is not first-order axiomatizable, for it requires every subset of the domain to have a fusion. In recent literature, a first-order theory named General Extensional Mereology can be thought of as a first-order approximation of Leśniewski’s theory, in the sense that GEM guarantees that every definable subset of the domain has a fusion, (...) and this has been achieved by positing an axiom schema which in effect defines infinitely many axioms. Intuitively, in order to range over every definable subset, such an axiom schema seems unavoidable. But this paper will show that GEM is finitely axiomatizable and that all we need are just finitely many instances of the said axiom schema. (shrink)

The signature of the formal language of mereotopology contains two predicates $P$ and $C$, which stand for “being a part of” and “contact,” respectively. This paper will deal with the decidability issue of the mereotopological theories which can be formed by the axioms found in the literature. Three main results to be given are as follows: all axiomatized mereotopological theories are separable; all mereotopological theories up to $\mathbf{ACEMT}$, $\mathbf{SACEMT}$, or $\mathbf{SACEMT}^{\prime}$ are finitely inseparable; all axiomatized mereotopological theories except $\mathbf{SAX}$, $\mathbf{SAX}^{\prime}$, (...) or $\mathbf{S\overline{B}X}^{\prime}$, where $\mathbf{X}$ is strictly stronger than $\mathbf{CEMT}$, are undecidable. Then it can also be easily seen that all axiomatized mereotopological theories proved to be undecidable here are neither essentially undecidable nor strongly undecidable but are hereditarily undecidable. Result will be shown by constructing strongly undecidable mereotopological structures based on two-dimensional Euclidean space, and it will be pointed out that the same construction cannot be carried through if the language is not rich enough.

This paper conducts a comparative analysis of data governance mechanisms concerning the secondary use of health data in Taiwan and the European Union (EU). Both regions have adopted distinctive approaches and regulations for utilizing health data beyond primary care, encompassing areas such as medical research and healthcare system enhancement. Through an examination of these models, this study seeks to elucidate the strategies, frameworks, and legal structures employed by Taiwan and the EU to strike a delicate balance between the imperative of (...) data-driven healthcare innovation and the safeguarding of individual privacy rights. This paper examines and compares several key aspects of the secondary use of health data in Taiwan and the EU. These aspects include data governance frameworks, legal and regulatory frameworks, data access and sharing mechanisms, and privacy and security considerations. This comparative exploration offers invaluable insights into the evolving global landscape of health data governance. It provides a deeper understanding of the strategies implemented by these regions to harness the potential of health data while upholding the ethical and legal considerations surrounding its secondary use. The findings aim to inform best practices for responsible and effective health data utilization, particularly in the context of medical AI applications. (shrink)

Mereological theories are based on the binary relation “being a part of”. The systematic investigations of mereology were initiated by Leśniewski. More recent authors (including Simons, Casati and Varzi, Hovda) formulated a series of first‐order mereological axioms. These axioms give rise to a plenitude of theories, which are of great philosophical interest. The paper considers first‐order mereological theories from the point of view of computable (or effective) algebra. Following the approach of Hirschfeldt, Khoussainov, Shore, and Slinko, we isolate two important (...) computability‐theoretic properties P (namely, degree spectra of structures, and effective dimensions), and consider the following problem: for a given mereological theory T, is it true that its models can realize every possible variant of the property P? If the answer is positive, then we say that the theory T is ‐universal. We obtain the following results about known mereological theories. Any theory T which is weaker than Extensional Closure Mereology (CEM) is ‐universal. A similar fact is true for the theory GM2. On the other hand, any theory stronger that CEM + (C) + (G) is not ‐universal. In particular, General Extensional Mereology is not ‐universal. (shrink)

This paper will first introduce first-order mereotopological axioms and axiomatized theories which can be found in some recent literature and it will also give a survey of decidability, undecidability as well as other relevant notions. Then the main result to be given in this paper will be the finite inseparability of any mereotopological theory up to atomic general mereotopology (AGEMT) or strong atomic general mereotopology (SAGEMT). Besides, a more comprehensive summary will also be given via making observations about other properties (...) stronger than undecidability. (shrink)

Selim Berker argues that epistemic consequentialism is pervasive in epistemology and that epistemic consequentialism is structurally flawed. is incorrect, however. I distinguish between epistemic consequentialism and epistemic instrumentalism and argue that most putative consequentialists should be considered instrumentalists. I also identify the structural problem of epistemic consequentialism Berker attempts to pinpoint and show that epistemic instrumentalism does not have the consequentialist problem.

To explain why we should be structurally rational – or mentally coherent – is notoriously difficult. Some philosophers argue that the normativity of structural rationality can be explained in terms of substantive rationality, which is a matter of correct response to reason. I argue that the psychological phenomena – positive illusions – are counterexamples to the substantivist approach. Substantivists dismiss the relevance of positive illusions because they accept evidentialism that reason for belief must be evidence. I argue that their evidentialist (...) stance would imply that we are caught in unsolvable dilemmas arising from positive illusions. (shrink)

Virtue epistemology maintains that epistemic normativity is a kind of performance normativity, according to which evaluating a belief is like evaluating a sport or musical performance. I examine this thesis through the objection that a belief cannot be evaluated as a performance because it is not a performance but a state. I argue that virtue epistemology can be defended on the grounds that we often evaluate a performance through evaluating the result of the performance. The upshot of my account is (...) that when a belief is evaluated under performance normativity, what we evaluate is not belief, but cognitive performance. My account of virtue epistemology offers a simple explanation of why knowledge is more valuable than true belief. (shrink)

A popular evidentialist argument against pragmatism is based on reason internalism: the view that a normative reason for one to φ must be able to guide one in normative deliberation whether to φ. In the case of belief, this argument maintains that, when deliberating whether to believe p, one must deliberate whether p is true. Since pragmatic considerations cannot weigh in our deliberation whether p, the argument concludes that pragmatism is false. I argue that evidentialists fail to recognize that the (...) question whether to φ is essentially the question whether one should φ. Furthermore, the question of whether one should believe p can be answered on pragmatic grounds. The internalist argument turns out to favor pragmatism. (shrink)

Virtue epistemology argues that knowledge is more valuable than Gettierized belief because knowledge is an achievement, but Gettierized belief is not. The key premise in the achievement argument is that achievement is apt (successful because competent) and Gettierized belief is inapt (successful because lucky). I first argue that the intuition behind the achievement argument is based wrongly on the fact that ‘being successful because lucky’ implicates ‘being not competent enough’. I then offer an argument from moral luck to argue that (...) virtue epistemologists should maintain that knowledge is no more valuable than Gettierized belief. (shrink)

如果機器人的發展要能如科幻想像一般，在沒有人類監督下自動地工作，就必須確定機器人不會做出道德上錯誤的行為。 根據行為主義式的道德主體觀，若就外顯行為來看，機器人在道德上的表現跟人類一般，機器人就可被視為道德主體。從這很自然地引伸出機器人的道德擬人主義：凡適用於人類的道德規則就適用於機器人。我反對道德擬人主義 ，藉由史特勞森對於人際關係與反應態度的洞見，並以家長主義行為為例，我論述由於機器人缺乏人格性，無法參與人際關係，因此在關於家長主義行為上，機器人應該比人類受到更嚴格的限制。.

It is widely maintained that doxastic norms that govern how people should believe can be explained by the truism that belief is governed by the correctness norm: believing p is correct if and only if p. This approach fails because it confuses two kinds of correctness norm: (1) It is correct for S to believe p if and only p; and (2) believing p is correct qua belief if and only if p. Only can (2) be said to be a (...) truism about belief, but it cannot ground doxastic norms. (shrink)

According to some philosophers, if moral agency is understood in behaviourist terms, robots could become moral agents that are as good as or even better than humans. Given the behaviourist conception, it is natural to think that there is no interesting moral difference between robots and humans in terms of moral agency (call it the _equivalence thesis_). However, such moral differences exist: based on Strawson’s account of participant reactive attitude and Scanlon’s relational account of blame, I argue that a distinct (...) kind of reason available to humans—call it _human-relative reason_—is not available to robots. The difference in moral reason entails that sometimes an action is morally permissible for humans, but not for robots. Therefore, when developing moral robots, we cannot consider only what humans can or cannot do. I use examples of paternalism to illustrate my argument. (shrink)

A virtue-based theory of right action aims to explain deontic moral principles in terms of virtue and vice. For example, it may maintain the following account of moral obligation: It is morally obligatory for an agent A to ϕ in circumstances C if and only if a fully virtuous and relevantly informed person V would characteristically ϕ in C. However, this account faces the so-called supererogation problem. A supererogatory action is an action that is morally praiseworthy but not morally obligatory. (...) Suppose John risks his own life to save a stranger, which is supererogatory rather than obligatory. However, a fully virtuous... (shrink)

Gettier cases are scenarios conceived by philosophers to demonstrate that justified true beliefs may not be knowledge. Starmans and Friedman (2020) find that philosophers attribute knowledge in Gettier cases differently from laypeople and non‐philosophy academics, which seems to suggest that philosophers may be indoctrinated to adopt an esoteric concept of knowledge. I argue to the contrary: Their finding at most shows that philosophical reflection is fallible, but nevertheless able to clarify the concept of knowledge. I also suggest that their experiments (...) could be modified to help determine when philosophical reflection might yield plausible results. (shrink)

This paper is to propose a new form of Kant’s anti-skepticism argument in light of John McDowell’s works on disjunctivism. I first discuss recent debates between McDowell and Crispin Wright on disjunctivism. I argue that Wright wrongly downplays McDowell’s disjunctivism, whose metaphysical claim that our perceptual faculties directly engage in the world has an epistemological implication that should be able to dismiss the skeptic’s imagery as fictitious. However, McDowell does not clearly offer such an argument. I will show that we (...) can derive from Kant’s Fourth Paralogism of the first edition of the Critique of Pure Reason—which many scholars regard as Kant’s implicit commitment to phenomenalism—the requisite argument that makes us able to dismiss skepticism.

Some philosophers argue that pain is an object located in bodily parts because the locative form of pain report is permissible in English. To examine this argument, Liu and Klein recently argue that the linguistic argument cannot work because the locative form is impermissible in Mandarin. They are wrong, however. I demonstrate that the locative form in Mandarin is not only permissible but also common.
