This chapter examines the basic grammatical and semantic features of knowledge verbs in Chinese—_renshi, zhidao_, and _liaojie_—and compares them with their counterparts in English and Japanese. The comparison is mainly based on lexical aspects like being stative or nonstative, whether they express in their basic forms a state, or an event, and so on. The authors then examine whether these verbs allow uses in orders, combine with some auxiliary verbs like the counterparts of “decide to,” “want to,” and the like (which suggest the possibility or the degree of voluntary control). Finally, they propose a possible “order of activity implication” among _zhidao_, “know,” and two Japanese knowledge verbs.

Can we see AI as a testifier? Or can it be no more than a tool? Earlier (Ryan, S., Mi, C., & Mizumoto, M. (2020). Testimony, credit, and blame. Ethno-epistemology: New directions for global epistemology. Routledge), conducted a cross-cultural study to empirically examine the Credit View of Knowledge, using Lackey’s Chicago Visitor case. Building on that study, we examined the patterns of people’s testimonial knowledge attribution by comparing a case in which the true belief of an agent is based on the testimony of a human and a case in which it is based on the “testimony” of an AI assistant. We found that people responded differently to the two cases, especially in their reasons for attributing knowledge to the recipient of testimony, differentiating the epistemic role of the recipient of testimony in the two cases, suggesting that for ordinary people, AI is more like a tool than an agent—an important consideration for trust attributions. We discuss what our findings can tell us about the influence of AI on human relations. In particular, we are interested in how increased use of AI as an information source will influence knowledge attributions of humans as testifiers. Also, concerning the Credit View, insofar as the folk notion of credit is concerned, Lackey was right and knowledge is possible without credit, but our results may still be consistent with the Credit View if we reinterpret the notion of credit based on the notions of reliability and proper method, as diverging depending on whether the testifier is a human or an AI. Moreover, we found some important cultural differences, which deserve independent attention and discussion.

This article examines whether people share the Gettier intuition (viz. that someone who has a true justified belief that p may nonetheless fail to know that p) in 24 sites, located in 23 countries (counting Hong Kong as a distinct country) and across 17 languages. We also consider the possible influence of gender and personality on this intuition with a very large sample size. Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to engage in “reflective” thinking.

In this paper, we will report results of two sets of cross-linguistic studies about truth judgments and correctness judgments by speakers of English and Japanese, which will show a significant influence of a moral-political factor in an utterance on Japanese truth/correctness judgments. Following up Mizumoto (2022), which demonstrated such an effect on Japanese truth judgments and correctness judgments about utterances containing a contrastive conjunction (such as “but”), Study 1 shows the same effect on Japanese correctness judgments about utterances containing a pejorative. Study 2 then shows that a moral-political factor in utterances can affect Japanese truth/correctness judgments about them even if they are simple utterances containing neither a contrastive conjunction nor a pejorative. In conclusion, we will briefly discuss whether this effect is linguistic or psychological, and present three hypotheses: the semantic hypothesis, pragmatic hypothesis, and error theory hypothesis, to account for the data, which we leave open for future studies.

In this paper, we present results of cross-linguistic studies of Japanese and English knowing how constructions that show radical differences in knowledge-how attributions with large effect sizes. The results suggest that the relevant ability is neither necessary nor sufficient for knowledge-how captured by Japanese constructions. We shall argue that such data will open up a gap between otherwise indistinguishable two conceptions of the very topic of knowledge-how, or the debate between intellectualism and anti-intellectualism, namely a debate about the nature of knowledge-how and a debate about the state captured by “know how”, which we call the knowledge-how interpretation and the state interpretation, respectively. Consequently, the results have not only various possible philosophical implications that have not been considered or discussed in the literature but also provide new topics in the theory of knowledge-how, including the question of which interpretation of the topic is correct itself.

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

Philosophers have long debated whether, if determinism is true, we should hold people morally responsible for their actions since in a deterministic universe, people are arguably not the ultimate source of their actions nor could they have done otherwise if initial conditions and the laws of nature are held fixed. To reveal how non-philosophers ordinarily reason about the conditions for free will, we conducted a cross-cultural and cross-linguistic survey (N = 5,268) spanning twenty countries and sixteen languages. Overall, participants tended to ascribe moral responsibility whether the perpetrator lacked sourcehood or alternate possibilities. However, for American, European, and Middle Eastern participants, being the ultimate source of one’s actions promoted perceptions of free will and control as well as ascriptions of blame and punishment. By contrast, being the source of one’s actions was not particularly salient to Asian participants. Finally, across cultures, participants exhibiting greater cognitive reflection were more likely to view free will as incompatible with causal determinism. We discuss these findings in light of documented cultural differences in the tendency toward dispositional versus situational attributions.

This chapter tries to elucidate the complex relationship between ordinary language philosophyordinary language philosophy (OLP) and experimental philosophy (X-Phi) from the perspective of the contrast between the positive and the negative programs of X-Phi. I will first show the relevance of language to the various fields of contemporary philosophy, through what I call the Argument from Cross-Linguistic Diversity and the Argument from Intra-Linguistic Variance, together with empirical data. This will partly vindicate OLP, which is generally thought to be obsolete today. I will then examine the reasons for the demise of OLP, and show that the contemporary meta-philosophical debates over X-Phi are in fact a revival of the debates in the heyday of OLP. This will then also indicate a parallel between Wittgenstein’s negative programnegative program, called quietism, and the negative program of X-Phi, especially Stich’s. The positive program of X-Phi can no doubt contribute to science, but the question of whether it is philosophy may depend on our conception of philosophy. The negative program of X-Phi is no doubt philosophy, but the question is whether it can make any positive contribution to philosophy, let alone science. I will answer “yes” to it, by sketching a radical negative picture of philosophy in general.

In this paper we will propose a simple linguistic approach to the Knobe effect, or the moral asymmetry of intention attribution in general, which is just to ask the felicity judgments on the relevant sentences without any vignette at all. Through this approach we were in fact able to reproduce the Knobe effects in different languages, with large effect sizes. We shall defend the significance of this simple approach by arguing that our approach and its results not only tell interesting facts about the concept of intentional action, but also show the existence of the linguistic default, which requires independent investigation. We will then argue that, despite the recent view on experimental philosophy by Knobe himself, there is a legitimate role of the empirical study of concepts in the investigations of cognitive processes in mainstream experimental philosophy, which suggests a broadly supplementary picture of experimental philosophy.

Finally, we examine whether the Gettier intuition varies across people as a function of their disposition to engage in “reflective” thinking.

This chapter presents two cross-linguistic studies of knowledge-how attributions that compare English and Japanese speakers. The first study investigates the felicity judgements of ordinary people about knowledge-how sentences, where we find a large difference in judgements about the sentences in which a person lacks an ability to perform a certain action but is nevertheless attributed the relevant knowledge of how to perform that action. The second study investigates the frequency of the natural occurrences of knowing-how constructions in English and Japanese through Google search and corpora, where we find virtually no natural occurrence of Japanese knowing-how constructions. These results suggest that the attribution of knowledge-how in Japanese is radically different from the English counterpart in that it neither requires nor is required by the relevant physical ability. We then explore the philosophical implications of these radical differences in the use of knowing-how constructions between English and Japanese speakers for the debate between intellectualism and anti-intellectualism. One such implication is that English “know how” sentences themselves may not delineate a philosophically significant category of knowledge.

This paper examines ordinary people’s responses to Jennifer Lackey’s Chicago Visitor case. In particular it examines responses regarding the case from participants with Taiwanese backgrounds and US backgrounds. The Chicago Visitor case is one of the most influential cases in epistemology in recent years and plays a significant role in a number of debates in epistemology. First, the case is used to suggest that the Credit View is mistaken. Second, the case seems to pose a problem for a virtue epistemological account of the nature of knowledge. Our paper explores these points in relation to our survey results, which show that participants believe that the protagonist in the case does have knowledge and that the protagonist deserves some credit for his true belief. Our aim in this paper, however, isn’t only to discover evidence bearing on the discussion of the Chicago Visitor case and cross cultural differences related to that case, we are also interested in what else the case might tell us about epistemic agency. For this reason we also asked participants to tell us to what extent they thought that the protagonist would be at fault in a case in which their belief turned out to be false. Here most of the participants found that the protagonist would indeed bear some fault in such circumstances. Our survey results also show, however, that participants of US background tend to be likely to attribute less fault to the testimonial recipient in bad testimonial cases, than their Taiwanese counterparts. More generally, we explore what the result regarding fault can tell us about epistemic agency.

In this paper, we propose and justify the cross‐linguistic study of the concept of truth through empirical studies of truth predicates, with results of such studies. We first conceptually explore the possibility of cross‐linguistic disagreement about truth purely due to linguistic norms governing truth predicates, which may imply a kind of pluralism about the concept of truth. We then consider the conditions under which we would be justified in inferring this sort of pluralism from the fact of such cross‐linguistic disagreement. Next, we report results of three studies on the use of English “is true” and Japanese two truth predicates, as well as “is correct” and its Japanese counterpart. We then report another set of studies using a different vignette, where the radical cross‐linguistic difference observed in earlier studies disappeared. These data together suggest that the moral‐political factor in the truth‐bearer (utterance) strongly affects the uses of Japanese truth predicates but not those of English. Finally, we will discuss the implications of the studies and results reported here, and the empirical possibility of what we call lexical alethic pluralism, for debates over relativism, theories of meaning, and the deflationary and inflationary theories of truth.

In this paper, we present what we call the argument from accidental truth, according to which some instances of deflationist schemata, even those carefully reformulated and adjusted by Field and Horwich to accommodate the truth of utterances, are falsified due to accidental truths. Since the folk concept of truth allows for accidental truths, the deflationary theory of truth will face a serious problem. In particular, it follows that the deflationist schema fails to capture the proper extension of truth by precluding accidental truths of utterances. Even though the argument uses the contextualist cases, this conclusion does not require so much as the truth of contextualism, but only two assumptions, the existence of context-relative non-literal contents of utterances (or speech acts), and the existence of accidental truths, both of which are widely accepted by folks and theorists. We will also consider various responses to the argument, including the revisionary deflationist position, all of which we argue are unsatisfactory or committed to a highly implausible view.

This chapter examines two Japanese (purported) knowledge verbs, _shitte-iru_ and _wakatte-iru_, first through the data of felicity judgment and then data from questionnaire surveys with standard epistemological vignettes. Even though they are mostly intersubstitutable, such data show significant differences in usage, where _shitte-iru_ seems independent of practical concerns while _wakatte-iru_ looks sensitive to practical abilities. The comparison with the English “know” shows that it is consistently closer to _wakatte-iru_, contrary to what almost all Japanese speakers think. But the differences between _shitte-ir_u and _wakatte-iru_ correspond to the many debates in anglophone epistemology, which raises a serious question about the nature of the debates therein, or even the nature of epistemology in general.

This volume features new perspectives on the implications of cross-linguistic and cultural diversity for epistemology. It brings together philosophers, linguists, and scholars working on knowledge traditions to advance work in epistemology that moves beyond the Anglophone sphere. The first group of chapters provide evidence of cross-linguistic or cultural diversity relevant to epistemology and discuss its possible implications. These essays defend epistemic pluralism based on Sanskrit data as a commitment to pluralism about epistemic stances, analyze the use of two Japanese knowledge verbs in relation to knowledge how, explore the Confucian notion of justification, and surveys cultural differences about the testimonial knowledge. The second group of chapters defends "core monism"--which claims that despite the cross-linguistic diversity of knowledge verbs, there is certain core epistemological meaning shared by all languages--from both a Natural Semantic Metalanguage and skeptical perspective. The third cluster of essays considers the implications of cultural diversity for epistemology based on anthropological studies. These chapters explore real disparities in folk epistemology across cultures. Finally, the last two chapters discuss methods or perspectives to unify epistemology despite and based on the diversity of folk intuitions and epistemological concepts. Ethno-Epistemology is an essential resource for philosophers working in epistemology and comparative philosophy, as well as linguists and cultural anthropologists interested in the cultural-linguistic diversity of knowledge traditions.

Since at least Hume and Kant, philosophers working on the nature of aesthetic judgment have generally agreed that common sense does not treat aesthetic judgments in the same way as typical expressions of subjective preferences—rather, it endows them with intersubjective validity, the property of being right or wrong regardless of disagreement. Moreover, this apparent intersubjective validity has been taken to constitute one of the main explananda for philosophical accounts of aesthetic judgment. But is it really the case that most people spontaneously treat aesthetic judgments as having intersubjective validity? In this paper, we report the results of a cross‐cultural study with over 2,000 respondents spanning 19 countries. Despite significant geographical variations, these results suggest that most people do not treat their own aesthetic judgments as having intersubjective validity. We conclude by discussing the implications of our findings for theories of aesthetic judgment and the purpose of aesthetics in general.

According to Bengson et al.’s Salchow case, Irina is a novice skater who has a mistaken belief about what amounts to a Salchow, but also has a neurological abnormality which, unknowingly to her, affects both her movement and her sense of it. As a result of this twist, she always ends up succeeding in jumping the Salchow whenever she tries. This story was presented as a counterexample to a variant of anti-intellectualism, and as Bengson and colleagues expected, the vast majority of participants in their survey judged both that Irina is able to do the Salchow and that she does not know how to do it. But the three conditions above leave some ambiguity about the story. That is whether Irina is aware of her own ability, or whether she is aware of what she is doing when she performs it, and therefore the fact that she can reliably perform the Salchow. However, as we report here, disambiguating this point will radically change the responses of people, which rather poses a serious challenge to intellectualism.

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

Since the heyday of ordinary language philosophy, Anglophone epistemologists have devoted a great deal of attention to the English word ‘know’ and to English sentences used to attribute knowledge. Even today, many epistemologists, including contextualists and subject-sensitive invariantists are concerned with the truth conditions of “S knows that p,” or the proposition it expresses. In all of this literature, the method of cases is used, where a situation is described in English, and then philosophers judge whether it is true that S knows that p, or whether saying “S knows that p” is false, deviant, etc. in that situation. However, English is just one of over 6000 languages spoken around the world, and is the native language of less than 6% of the world’s population. When Western epistemology first emerged, in ancient Greece, English did not even exist. So why should we think that facts about the English word “know,” the concept it expresses, or subtle semantic properties of “S knows that p” have important implications for epistemology? Are the properties of the English word “know” and the English sentence ‘S knows that p’ shared by their translations in most or all languages? If that turned out to be true, it would be a remarkable fact that cries out for an explanation. But if it turned out to be false, what are the implications for epistemology? Should epistemologists study knowledge attributions in languages other than English with the same diligence they have shown for the study of English knowledge attributions? If not, why not? In what ways do the concepts expressed by ‘know’ and its counterparts in different languages differ? And what should epistemologists make of all this?

The Blinking Qualia Argument is the argument presented in Mizumoto (2006), which is to establish that zombies are impossible a priori. In this paper I will defend the argument from the actual and possible criticisms. Since such criticisms mainly focus on the premise “If qualia blinks, the subject can notice the blinking qualia,” I will give arguments to specifically defend that premise. This will bring into light the critic’s misunderstandings on the argument, and more generally, typical misunderstandings surrounding the debates over the possibility of zombies, concerning the very concept of qualia.
