Aim: Low professional help-seeking intention (PHSI) hinders effective treatment of mental illness. PHSI among Chinese students is still understudied and under-recognized. This study aimed to evaluate the status of PHSI and its associated risk factors among Chinese medical students. -/- Methods: A cross-sectional survey was conducted in Hainan province, South China, between January 1, 2021, and May 31, 2021. A total of 2182 medical students were recruited and surveyed via an anonymous structured questionnaire. Logistic regression analyses were performed to identify (...) the factors associated with PHSI. -/- Results: Among the 2182 medical students (mean age 21.0 years (SD = 3.70), 61.5% females), those with and without PHSI were 72.0% and 28.0%, and 16.4% with moderate to severe depression. Male students, those with a high level of depression stigma, serious family dysfunction, and heavy dependence on mobile phones were significantly less likely to seek professional mental health help, with odds ratios (ORs) of 1.5, 2.0, 2.1, and 1.7, respectively. -/- Conclusion: A significant proportion of Chinese medical students demonstrate low PHSI, influenced by factors such as gender, depression stigma, family dysfunction, and mobile phone dependence. Future interventions aimed at increasing medical students’ PHSI should prioritize reducing depression stigma, mitigating reliance on mobile phone use, and enhancing family function to address these key barriers to seeking professional mental health support.

Ontologies, as the term is used in informatics, are structured vocabularies comprised of human- and computer-interpretable terms and relations that represent entities and relationships. Within informatics fields, ontologies play an important role in knowledge and data standardization, representation, integra- tion, sharing and analysis. They have also become a foundation of artificial intelligence (AI) research. In what follows, we outline the Coronavirus Infectious Disease Ontology (CIDO), which covers multiple areas in the domain of coronavirus diseases, including etiology, transmission, epidemiology, pathogenesis, diagnosis, (...) prevention, and treatment. We emphasize CIDO development relevant to COVID-19. (shrink)

Current COVID-19 pandemic and previous SARS/MERS outbreaks have caused a series of major crises to global public health. We must integrate the large and exponentially growing amount of heterogeneous coronavirus data to better understand coronaviruses and associated disease mechanisms, in the interest of developing effective and safe vaccines and drugs. Ontologies have emerged to play an important role in standard knowledge and data representation, integration, sharing, and analysis. We have initiated the development of the community-based Coronavirus Infectious Disease Ontology (CIDO). (...) As an Open Biomedical Ontology (OBO) library ontology, CIDO is an open source and interoperable with other existing OBO ontologies. In this article, the general architecture and the design patterns of the CIDO are introduced, CIDO representation of coronaviruses, phenotypes, anti-coronavirus drugs and medical devices (e.g. ventilators) are illustrated, and an application of CIDO implemented to identify repurposable drug candidates for effective and safe COVID-19 treatment is presented.

The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the (...) development of the community-based Coronavirus Infectious Disease Ontology in early 2020. -/- As an Open Biomedical Ontology (OBO) library ontology, CIDO is open source and interoperable with other existing OBO ontologies. CIDO is aligned with the Basic Formal Ontology and Viral Infectious Disease Ontology. CIDO has imported terms from over 30 OBO ontologies. For example, CIDO imports all SARS-CoV-2 protein terms from the Protein Ontology, COVID-19-related phenotype terms from the Human Phenotype Ontology, and over 100 COVID-19 terms for vaccines (both authorized and in clinical trial) from the Vaccine Ontology. CIDO systematically represents variants of SARS-CoV-2 viruses and over 300 amino acid substitutions therein, along with over 300 diagnostic kits and methods. CIDO also describes hundreds of host-coronavirus protein-protein interactions (PPIs) and the drugs that target proteins in these PPIs. CIDO has been used to model COVID-19 related phenomena in areas such as epidemiology. The scope of CIDO was evaluated by visual analysis supported by a summarization network method. CIDO has been used in various applications such as term standardization, inference, natural language processing (NLP) and clinical data integration. We have applied the amino acid variant knowledge present in CIDO to analyze differences between SARS-CoV-2 Delta and Omicron variants. CIDO's integrative host-coronavirus PPIs and drug-target knowledge has also been used to support drug repurposing for COVID-19 treatment. -/- CIDO represents entities and relations in the domain of coronavirus diseases with a special focus on COVID-19. It supports shared knowledge representation, data and metadata standardization and integration, and has been used in a range of applications. (shrink)

COVID-19 often manifests with different outcomes in different patients, highlighting the complexity of the host-pathogen interactions involved in manifestations of the disease at the molecular and cellular levels. In this paper, we propose a set of postulates and a framework for systematically understanding complex molecular host-pathogen interaction networks. Specifically, we first propose four host-pathogen interaction (HPI) postulates as the basis for understanding molecular and cellular host-pathogen interactions and their relations to disease outcomes. These four postulates cover the evolutionary dispositions involved (...) in HPIs, the dynamic nature of HPI outcomes, roles that HPI components may occupy leading to such outcomes, and HPI checkpoints that are critical for specific disease outcomes. Based on these postulates, an HPI Postulate and Ontology (HPIPO) framework is proposed to apply interoperable ontologies to systematically model and represent various granular details and knowledge within the scope of the HPI postulates, in a way that will support AI-ready data standardization, sharing, integration, and analysis. As a demonstration, the HPI postulates and the HPIPO framework were applied to study COVID-19 with the Coronavirus Infectious Disease Ontology (CIDO), leading to a novel approach to rational design of drug/vaccine cocktails aimed at interrupting processes occurring at critical host-coronavirus interaction checkpoints. Furthermore, the host-coronavirus protein-protein interactions (PPIs) relevant to COVID-19 were predicted and evaluated based on prior knowledge of curated PPIs and domain-domain interactions, and how such studies can be further explored with the HPI postulates and the HPIPO framework is discussed.

He drove a taxi. Now he drives a truck. So, must he be driving the truck right now? Must he, as long as he's working as a truck driver, keep driving his truck all day and all night? What do we speak of, when we speak of "now"? In this talk, some popular conceptions in the philosophy of time will be put under critical scrutiny: (1) The present (the "now") is an instant, a time point with no length; (2) the (...) "content" of the present is always an event, a happening, which constitutes a segment of a larger process; (3) what (time) is now, is determined by the passage of time (itself). The following points will be defended respectively: (1) The present may be a time period. "Now" is not an indivisible time-atom in the substantival sense. (2) What is now can be an event, a process, or a state. "Driving a truck now" – in the sense of being a truck driver – is neither an event nor something happening to him. (3) "Now", among other temporal concepts, is not a name for any thing, but schemata under which we understand ways things being themselves. There are variety of ways of being, and accordingly there are multiple aspects of now-ness. (shrink)

The Shape-of-a-Life phenomenon is widely recognized by philosophers of well-being: an upward life trajectory seems better than its downward equivalent if the sum of momentary well-being is held fixed. But what if we hold fixed the sum of momentary well-being in an upward trajectory, are certain ways to improve from the bad times better than the others? Velleman suggests that a redemptive trajectory is better than a bare upward trajectory. In this paper, I elaborate this proposal by developing a mediating (...) factor account of prudential redemption. I argue that, in redemptive trajectories, there is a mediating factor that bears certain relations with the negative and the positive events respectively, one that does not necessarily appear in bare upward trajectories. Prudential redemption, compared to mere improvement, can enhance a person’s lifetime well-being because a redeemed event is made less bad by virtue of the mediating factor. This result has implications for making decisions in the face of equally good options and for evaluating the rationality of honoring sunk costs. (shrink)

Zeugmatic oddness is a linguistic intuition of oddness with respect to an instance of zeugma, i.e. a sentence containing an instance of a homonymous or polysemous word being used in different meanings or senses simultaneously. Zeugmatic oddness is important for philosophical debates as philosophers often use it to argue that a particular philosophically interesting expression is ambiguous and that the phenomenon referred to by the expression is disunified. This paper takes a closer look at zeugmatic oddness. Focusing on relevant psycholinguistic (...) literature on homonymy and polysemy processing and representation, I argue that there are two different ways in which zeugmatic oddness can arise. Philosophical upshots concerning zeugmatic oddness are then drawn. (shrink)

The paradox of pain refers to the idea that the folk concept of pain is paradoxical, treating pains as simultaneously mental states and bodily states. By taking a close look at our pain terms, this paper argues that there is no paradox of pain. The air of paradox dissolves once we recognize that pain terms are polysemous and that there are two separate but related concepts of pain rather than one.

Slurs are derogatory words and they are used to derogate certain groups. Theories of slurs must explain why they are derogatory words, as well as other features like independence and descriptive ineffability. This paper proposes an illocutionary force indicator theory of slurs: they are derogatory terms because their use is to perform the illocutionary act of derogation, which is a declarative illocutionary act to enforce norms against the target. For instance, calling a Chinese person “chink” is an act of derogation (...) to enforce racist norms that license exclusion of the Chinese, deny their rights to dignity, etc. The contribution of this paper is twofold. First, it offers a more comprehensive explanation of the features of slurs than earlier speech act approaches. Second, it provides a theory that is immune to the problems faced by existing theories, such as wrong predictions of truth-conditions, explaining unacceptability to non-bigots, and explaining slurs against the dominant groups.

Can an agent deliberating about an action A hold a meaningful credence that she will do A? 'No', say some authors, for 'Deliberation Crowds Out Prediction' (DCOP). Others disagree, but we argue here that such disagreements are often terminological. We explain why DCOP holds in a Ramseyian operationalist model of credence, but show that it is trivial to extend this model so that DCOP fails. We then discuss a model due to Joyce, and show that Joyce's rejection of DCOP rests (...) on terminological choices about terms such as 'intention', 'prediction', and 'belief'. Once these choices are in view, they reveal underlying agreement between Joyce and the DCOP-favouring tradition that descends from Ramsey. Joyce's Evidential Autonomy Thesis (EAT) is effectively DCOP, in different terminological clothing. Both principles rest on the so-called 'transparency' of first-person present-tensed reflection on one's own mental states. (shrink)

There is a long-standing disagreement in the philosophy of probability and Bayesian decision theory about whether an agent can hold a meaningful credence about an upcoming action, while she deliberates about what to do. Can she believe that it is, say, 70% probable that she will do A, while she chooses whether to do A? No, say some philosophers, for Deliberation Crowds Out Prediction (DCOP), but others disagree. In this paper, we propose a valid core for DCOP, and identify terminological (...) causes for some of the apparent disputes. (shrink)

In a recent paper, Reuter, Seinhold and Sytsma put forward an implicature account to explain the intuitive failure of the pain-in-mouth argument. They argue that utterances such as ‘There is tissue damage / a pain / an inflammation in my mouth’ carry the conversational implicature that there is something wrong with the speaker’s mouth. Appealing to new empirical data, this paper argues against the implicature account and for the entailment account, according to which pain reports using locative locutions, such as (...) ‘There is a pain in my mouth’, are intuitively understood as entailing corresponding predicative locutions, such as ‘My mouth hurts.’ On this latter account, the pain-in-mouth argument seems invalid because the conclusion is naturally understood as entailing something which cannot be inferred from the premisses. Implications for the philosophical debate about pain are also drawn. (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)

This commentary focuses on explaining the intuition of revelation, an issue that Chalmers (2018) raises in his paper. I first sketch how the truth of revelation provides an explanation for the intuition of revelation, and then assess a physicalist proposal to explain the intuition that appeals to Derk Pereboom’s (2011, 2016, 2019) qualitative inaccuracy hypothesis.

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

Philosophers disagree about what the folk concept of pain is. This paper criticises existing theories of the folk concept of pain, i.e. the mental view, the bodily view, and the recently proposed polyeidic view. It puts forward an alternative proposal – the polysemy view – according to which pain terms like “sore,” “ache” and “hurt” are polysemous, where one sense refers to a mental state and another a bodily state, and the type of polysemy at issue reflects two distinct but (...) related concepts of pain. Implications with respect to issues in philosophy of pain are also drawn. (shrink)

Recent research in psycholinguistics suggests that language processing frequently involves mental imagery. This paper focuses on visual imagery and discusses two issues regarding the processing of polysemous words (i.e. words with multiple related meanings or senses) – co-predication and sense-relatedness. It aims to show how mental imagery can illuminate these two issues.

As the aim of the responsible robotics initiative is to ensure that responsible practices are inculcated within each stage of design, development and use, this impetus is undergirded by the alignment of ethical and legal considerations towards socially beneficial ends. While every effort should be expended to ensure that issues of responsibility are addressed at each stage of technological progression, irresponsibility is inherent within the nature of robotics technologies from a theoretical perspective that threatens to thwart the endeavour. This is (...) because the concept of responsibility, despite being treated as such, is not monolithic: rather this seemingly unified concept consists of converging and confluent concepts that shape the idea of what we colloquially call responsibility. From a different perspective, robotics will be simultaneously responsible and irresponsible depending on the particular concept of responsibility that is foregrounded: an observation that cuts against the grain of the drive towards responsible robotics. This problem is further compounded by responsible design and development as contrasted to responsible use. From a different perspective, the difficulty in defining the concept of responsibility in robotics is because human responsibility is the main frame of reference. Robotic systems are increasingly expected to achieve the human-level performance, including the capacities associated with responsibility and other criteria which are necessary to act responsibly. This subsists within a larger phenomenon where the difference between humans and non-humans, be it animals or artificial systems, appears to be increasingly blurred, thereby disrupting orthodox understandings of responsibility. This paper seeks to supplement the responsible robotics impulse by proposing a complementary set of human rights directed specifically against the harms arising from robotic and artificial intelligence technologies. The relationship between responsibilities of the agent and the rights of the patient suggest that a rights regime is the other side of responsibility coin. The major distinction of this approach is to invert the power relationship: while human agents are perceived to control robotic patients, the prospect for this to become reversed is beginning. As robotic technologies become ever more sophisticated, and even genuinely complex, asserting human rights directly against robotic harms become increasingly important. Such an approach includes not only developing human rights that ‘protect’ humans but also ‘strengthen’ people against the challenges introduced by robotics and AI [This distinction parallels Berlin’s negative and positive concepts of liberty ], by emphasising the social and reflective character of the notion of humanness as well as the difference between the human and nonhuman. This will allow using the human frame of reference as constitutive of, rather than only subject to, the robotic and AI technologies, where it is human and not technology characteristics that shape the human rights framework in the first place.

Philosophers debate over the truth of the Doctrine of Doing and Allowing, the thesis that there is a morally significant difference between doing harm and merely allowing harm to happen. Deontologists tend to accept this doctrine, whereas consequentialists tend to reject it. A robust defence of this doctrine would require a conceptual distinction between doing and allowing that both matches our ordinary use of the concepts in a wide range of cases and enables a justification for the alleged moral difference. (...) In this article, I argue not only that a robust defence of this doctrine is available, but also that it is available within a consequentialist framework. (shrink)

Slurs are both derogatory and offensive, and they are said to exhibit “derogatory force” and “offensiveness.” Almost all theories of slurs, except the truth-conditional content theory and the invocational content theory, conflate these two features and use “derogatory force” and “offensiveness” interchangeably. This paper defends and explains the distinction between slurs’ derogatory force and offensiveness by fulfilling three goals. First, it distinguishes between slurs’ being derogatory and their being offensive with four arguments. For instance, ‘Monday’, a slur in the Bostonian (...) argot, is used to secretly derogate African Americans without causing offense. Second, this paper points out that many theories of slurs run into problems because they conflate derogatory force with offensiveness. For example, the prohibition theory’s account of offensiveness in terms of prohibitions struggles to explain why ‘Monday’ is derogatory when it is not a prohibited word in English. Third, this paper offers a new explanation of this distinction from the perspective of a speech act theory of slurs; derogatory force is different from offensiveness because they arise from two different kinds of speech acts that slurs are used to perform, i.e., the illocutionary act of derogation and the perlocutionary act of offending. This new explanation avoids the problems faced by other theories. (shrink)

Since the early nineteenth century a membrane or wall has been central to the cell’s identity as the elementary unit of life. Yet the literally and metaphorically marginal status of the cell membrane made it the site of clashes over the definition of life and the proper way to study it. In this article I show how the modern cell membrane was conceived of by analogy to the first “artificial cell,” invented in 1864 by the chemist Moritz Traube (1826–1894), and (...) reimagined by the plant physiologist Wilhelm Pfeffer (1845–1920) as a precision osmometer. Pfeffer’s artificial cell osmometer became the conceptual and empirical basis for the law of dilute solutions in physical chemistry, but his use of an artificial analogue to theorize the existence of the plasma membrane as distinct from the cell wall prompted debate over whether biology ought to be more closely unified with the physical sciences, or whether it must remain independent as the science of life. By examining how the histories of plant physiology and physical chemistry intertwined through the artificial cell, I argue that modern biology relocated vitality from protoplasmic living matter to nonliving chemical substances—or, in broader cultural terms, that the disenchantment of life was accompanied by the (re)enchantment of ordinary matter.

A frequent caveat in online dating profiles – “No fats, femmes, or Asians” – caused an LGBT activist to complain about the bias against Asians in the American gay community, which he called “racial looksism”. In response, he was asked that, if he himself would not date a fat person, why he should find others not dating Asians so upsetting. This response embodies a popular attitude that personal preferences or tastes are simply personal matters – they are not subject to (...) moral evaluation. In this paper, I argue, against this popular attitude, that a personal preference like racial looksism is indeed wrong. A preference like racial looksism is wrong because it is an overgeneralization that disrespects individuality by treating people as exchangeable tokens of one type, and such disrespect denies its objects appreciation that their dignity entitles them to. As it turns out, there is on my account a relevant moral difference between racial looksism and simple looksism. (shrink)

Slurs are derogatory, and theories of slurs aim at explaining their “derogatory force”. This paper draws a distinction between the type derogatory force and the token derogatory force of slurs. To explain the type derogatory force is to explain why a slur is a derogatory word. By contrast, to explain the token derogatory force is to explain why an utterance of a slur is derogatory. This distinction will be defended by examples in which the type and the token derogatory force (...) come apart. Because of the distinction, an adequate theory of slurs must be plausible for both the type and the token derogatory force. However, I will argue that many theories fail to be plausible for both. In particular, Hom’s combinatorial externalism and the conventional implicature theory offer implausible accounts of the token derogatory force, whereas the prohibitionist theory is insufficient to explain the type derogatory force.

(Recipient of the 2020 Everett Mendelsohn Prize.) This article revisits the development of the protoplasm concept as it originally arose from critiques of the cell theory, and examines how the term “protoplasm” transformed from a botanical term of art in the 1840s to the so-called “living substance” and “the physical basis of life” two decades later. I show that there were two major shifts in biological materialism that needed to occur before protoplasm theory could be elevated to have equal status (...) with cell theory in the nineteenth century. First, I argue that biologists had to accept that life could inhere in matter alone, regardless of form. Second, I argue that in the 1840s, ideas of what formless, biological matter was capable of dramatically changed: going from a “coagulation paradigm” that had existed since Theophrastus, to a more robust conception of matter that was itself capable of movement and self-maintenance. In addition to revisiting Schleiden and Schwann’s original writings on cell theory, this article looks especially closely at Hugo von Mohl’s definition of the protoplasm concept in 1846, how it differed from his primordial utricle theory of cell structure two years earlier. This article draws on Lakoff and Johnson’s theory of “ontological metaphors” to show that the cell, primordial utricle, and protoplasm can be understood as material container, object, and substance, and that these overlapping distinctions help explain the chaotic and confusing early history of cell theory.

In recent literature on the metaphysics of consciousness, and in particular on the prospects of physicalism, there are two interesting strands of discussion. One strand concerns the so-called ‘thesis of revelation’, the claim that the essences of phenomenal properties are revealed in experience. The other strand concerns the intuition of dualism, the intuition that consciousness is nonphysical. With a particular focus on the former, this paper advances two main arguments. First, it argues that the thesis of revelation is intuitive; it (...) is part of our ordinary, implicit conception of experience. Second, it brings the two strands of discussion together and puts forward a rational explanation of the intuition of dualism in terms of the intuitiveness of the thesis of revelation. (shrink)

Poetry evokes mental imagery in its readers. But how is mental imagery precisely related to poetry? This article provides a systematic treatment. It clarifies two roles of mental imagery in relation to poetry—as an effect generated by poetry and as an efficient means for understanding and appreciating poetry. The article also relates mental imagery to the discussion on the ‘heresy of paraphrase’. It argues against the orthodox view that the imagistic effects of poetry cannot be captured by prosaic paraphrase, but (...) points to features of poetry that can shape aspects of mental imagery that are liable to be lost in paraphrase.

The feeling of being offended, as a moral emotion, plays a key role in issues such as slurs, the offense principle, ethics of humor, etc. However, no adequate theory of offense has been developed in the literature, and it remains unclear what questions such a theory should answer. This paper attempts to fill the gap by performing two tasks. The first task is to clarify and summarize the questions of offense into two kinds, the descriptive questions (e.g., what features differentiate (...) offense from similar moral states like anger?) and the normative questions (e.g., what are the conditions for taking offense to be apt?). The second task is to answer these questions by developing what I call ‘the violated norm theory of offense’. According to this theory, feeling offended entails that the norm one endorses is judged to be violated by the offender. Appealing to the violated norm enables this theory to answer the descriptive questions (e.g., taking offense differs from anger because of features like not requiring victims and the difficulty of animal offense) and the normative questions of offense (e.g., taking offense is apt only if the violated norm is universalizable).

This paper is an attempt to improve the practical argument for beliefs in God. Some theists, most famously Kant and William James, called our attention to a particular set of beliefs, the Jamesian-type beliefs, which are justified by virtue of their practical significance, and these theists tried to justify theistic beliefs on the exact same ground. I argue, contra the Jamesian tradition, that theistic beliefs are different from the Jamesian-type beliefs and thus cannot be justified on the same ground. I (...) also argue that the practical argument, as it stands, faces a problem of self-defeat. I then construct a new practical argument that avoids both problems. According to this new argument, theistic beliefs are rational to accept because such beliefs best supply us with motivation strong enough to carry out demanding moral tasks. (shrink)

This paper addresses the issue of finite versus countable additivity in Bayesian probability and decision theory -- in particular, Savage's theory of subjective expected utility and personal probability. I show that Savage's reason for not requiring countable additivity in his theory is inconclusive. The assessment leads to an analysis of various highly idealised assumptions commonly adopted in Bayesian theory, where I argue that a healthy dose of, what I call, conceptual realism is often helpful in understanding the interpretational value of (...) sophisticated mathematical structures employed in applied sciences like decision theory. In the last part, I introduce countable additivity into Savage's theory and explore some technical properties in relation to other axioms of the system. (shrink)

It is often thought that sensible qualities such as colours do not exist as properties of physical objects. Focusing on the case of colour, I discuss two views: the Galilean view, according to which colours do not exist as qualities of physical objects, and the naive view, according to which colours are, as our perception presents them to be, qualities instantiated by physical objects. I argue that it is far from clear that the Galilean view is better than the naive (...) view. Given the arguments in this paper, the naive view ought to be taken seriously. The discussion here appeals especially to theorists who, like Goff, are already convinced that the quantitative language of physical science fails to capture all qualities. (shrink)

The notion of comparative probability defined in Bayesian subjectivist theory stems from an intuitive idea that, for a given pair of events, one event may be considered “more probable” than the other. Yet it is conceivable that there are cases where it is indeterminate as to which event is more probable, due to, e.g., lack of robust statistical information. We take that these cases involve indeterminate comparative probabilities. This paper provides a Savage-style decision-theoretic foundation for indeterminate comparative probabilities.

Ad hoc concepts feature prominently in lexical pragmatics. A speaker can use a word or phrase to communicate an ad hoc concept that is different from the lexically encoded concept and the hearer can construct the intended ad hoc concept pragmatically during utterance comprehension. I argue that some philosophical concepts have origins as ad hoc concepts, and such concepts pose a challenge for experimental philosophy regarding these concepts. To illustrate this, I consider philosophers’ ‘what-it’s-like’-concepts and experimental philosophy of consciousness.

Empirical evidence suggests that perceptual‐motor simulations are often constitutively involved in language comprehension. Call this “the simulation view of language comprehension”. This article applies the simulation view to illuminate the much‐discussed phenomenon of copredication, where a noun permits multiple predications which seem to select different senses of the noun simultaneously. On the proposed account, the (in)felicitousness of a copredicational sentence is closely associated with the perceptual simulations that the language user deploys in comprehending the sentence.

In the philosophy of mind, revelation is the claim that the nature of qualia is revealed in phenomenal experience. In the literature, revelation is often thought of as intuitive but in tension with physicalism. While mentions of revelation are frequent, there is room for further discussion of how precisely to formulate the thesis of revelation and what it exactly amounts to. Drawing on the work of David Lewis, this paper provides a detailed discussion on how the thesis of revelation, as (...) well as its incompatibility with physicalism, is to be understood. (shrink)

Paintings of music are a significant presence in modern art. They are cross-modal representations, aimed at representing music, say, musical works or forms, using colors, lines, and shapes in the visual modality. This article aims to provide a conceptual framework for understanding paintings of music. Using examples from modern art, the article addresses the question of what a painting of music is. Implications for the aesthetic appreciation of paintings of music are also drawn.

This paper offers a fine analysis of different versions of the well known sure-thing principle. We show that Savage's formal formulation of the principle, i.e., his second postulate (P2), is strictly stronger than what is intended originally.

This paper begins with Thomas Nagel's (1970) investigation of the possibility of altruism to further examine how to motivate altruism. When the pursuit of the gratification of one's own desires generally has an immediate causal efficacy, how can one also be motivated to care for others and to act towards the well-being of others? A successful motivational theory of altruism must explain how altruism is possible under all these motivational interferences. The paper will begin with an exposition of Nagel's proposal, (...) and see where it is insufficient with regard to this further issue. It will then introduce the views of Zhang Zai and Wang Fuzhi, and see which one could offer a better motivational theory of altruism. All three philosophers offer different insights on the role of human reason/reflection and human sentiments in moral motivation. The paper will end with a proposal for a socioethical moral program that incorporates both moral reason and moral sentiments as motivation. (shrink)

Weakly Aggregative Modal Logic (WAML) is a collection of disguised polyadic modal logics with n-ary modalities whose arguments are all the same. WAML has some interesting applications on epistemic logic and logic of games, so we study some basic model theoretical aspects of WAML in this paper. Specifically, we give a van Benthem-Rosen characterization theorem of WAML based on an intuitive notion of bisimulation and show that each basic WAML system Kn lacks Craig Interpolation.

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

In this paper I argue against a deflationist view that as representational vehicles symbols and models do their jobs in essentially the same way. I argue that symbols are conventional vehicles whose chief function is denotation while models are epistemic vehicles whose chief function is showing what their targets are like in the relevant aspects. It is further pointed out that models usually do not rely on similarity or some such relations to relate to their targets. For that referential relation (...) they reply instead on symbols (names and labels) given to them and their parts. And a Goodmanian view on pictures of fictional characters reveals the distinction between symbolic and model representations. (shrink)

This paper presents a human-computer interaction model with a three layers learning mechanism in a pervasive environment. We begin with a discussion around a number of important issues related to human-computer interaction followed by a description of the architecture for a multi-agent cooperative design system for pervasive computing environment. We present our proposed three- layer HCI model and introduce the group formation algorithm, which is predicated on a dynamic sharing niche technology. Finally, we explore the cooperative reinforcement learning and fusion (...) algorithms; the paper closes with concluding observations and a summary of the principal work and contributions of this paper.

This paper defends an approach to modeling and models in science that is against model fictionalism of a recent stripe (the “new fictionalism” that takes models to be abstract entities that are analogous to works of fiction). It further argues that there is a version of fictionalism on models to which my approach is neutral and which only makes sense if one adopts a special sort of antirealism (e.g. constructive empiricism). Otherwise, my approach strongly suggests that one stays away from (...) fictionalism and embraces realism directly. (shrink)

Today, the lipid bilayer structure is nearly ubiquitous, taken for granted in even the most rudimentary introductions to cell biology. Yet the image of the lipid bilayer, built out of lipids with heads and tails, went from having obscure origins deep in colloid chemical theory in 1924 to being “obvious to any competent physical chemist” by 1935. This chapter examines how this schematic, strictly heuristic explanation of the idea of molecular orientation was developed within colloid physical chemistry, and how the (...) image was transformed into a reflection of the reality and agency of lipid molecules in the biological microworld. Whereas in physical and colloid chemistry these images considered secondary to instrumental measurement and mathematical modeling of surface phenomena, in biology the manipulable image of the lipid on paper became an essential tool for the molecularization of the cell.

Background -/- Previous literature suggests that those with reading disability (RD) have more pronounced deficits during semantic processing in reading as compared to listening comprehension. This discrepancy has been supported by recent neuroimaging studies showing abnormal activity in RD during semantic processing in the visual but not in the auditory modality. Whether effective connectivity between brain regions in RD could also show this pattern of discrepancy has not been investigated. Methodology/Principal Findings -/- Children (8- to 14-year-olds) were given a semantic (...) task in the visual and auditory modality that required an association judgment as to whether two sequentially presented words were associated. Effective connectivity was investigated using Dynamic Causal Modeling (DCM) on functional magnetic resonance imaging (fMRI) data. Bayesian Model Selection (BMS) was used separately for each modality to find a winning family of DCM models separately for typically developing (TD) and RD children. BMS yielded the same winning family with modulatory effects on bottom-up connections from the input regions to middle temporal gyrus (MTG) and inferior frontal gyrus(IFG) with inconclusive evidence regarding top-down modulations. Bayesian Model Averaging (BMA) was thus conducted across models in this winning family and compared across groups. The bottom-up effect from the fusiform gyrus (FG) to MTG rather than the top-down effect from IFG to MTG was stronger in TD compared to RD for the visual modality. The stronger bottom-up influence in TD was only evident for related word pairs but not for unrelated pairs. No group differences were noted in the auditory modality. Conclusions/Significance -/- This study revealed a modality-specific deficit for children with RD in bottom-up effective connectivity from orthographic to semantic processing regions. There were no group differences in connectivity from frontal regions, suggesting that the core deficit in RD is not in top-down modulation. (shrink)

It is often said that there is no appearance/reality distinction with respect to consciousness. Call this claim ‘NARD’. In contemporary discussions, NARD is closely connected to the thesis of revelation, the claim that the essences of phenomenal properties are revealed in experience, though the connection between the two requires clarification. This paper distinguishes different versions of NARD and homes in on a particular version that is closely connected to revelation. It shows how revelation and the related version of NARD pose (...) a threat to physicalism. Responses from physicalism and their limitations are also considered. (shrink)
