This introductory paper provides an overview of four contributions on the epistemological functions of mathematical symbolism as it emerged in Arabic and European treatises on algebra. The evolution towards symbolic algebra was a long and difficult process in which many obstacles had to be overcome. Three of these obstacles, related to the circulation and adoption of symbolism, are highlighted in this special volume: 1) the transition of material practices of algebraic calculation to discursive practices and text production, 2) the transition (...) from manuscript production to printed works involving material limitations of typefaces, and 3) the transition of algebraic symbolism from a system of notation and representation to a tool of mathematical analysis. This paper will conclude with the observation that the whole development towards symbolization can be considered an obstacle by itself in the sense of ‘epistemic obstacles’ as used by Brousseau.

The notion of “agent bookkeeping” was proposed when the “Accounting Law of the People’s Republic of China” was updated in 1993. Since their business is specialized in serving small and micro-enterprises, this has created the industry characteristic of generally small in the size of company and low in the salary of employees in Chinese agent bookkeeping companies. Such characteristic results in a series of problems including negative work attitude of employees in the development process, which seriously limit the development of (...) Chinese agent bookkeeping companies. However, issues occurred in the development of agent bookkeeping, such as negative employee attitudes, which severely hampered the growth of Chinese agent bookkeeping companies. Therefore, a model of three dimensions of work attitude has been set up in this paper to demonstrate the working attitude of the staff of the agent bookkeeping companies in China’s Guangdong-Hong Kong-Macao Greater Bay Area, including emotional dimension, behavioral dimension, and cognitive dimension which consists of eight factors: work environment, career satisfaction, interpersonal relationship, role engagement, work vitality, responsibility attitude, emotional identity, and retention attitude. The result indicates that female employees outnumber male ones in agent bookkeeping companies, most employees have a low sense of belonging to the company, limited career development affects employees’ enthusiasm for work, work attitudes are influenced by mediocre work performance among employees with a graduate degree or higher.

In this paper we examine whether the sense of agency represents an obstacle to the project of naturalizing the mental. On the basis of a thought experiment we suggest that the sense of agency is not an epiphenomenon. We also examine Frith's attempt to explain in functionalist terms the sense of agency through the comparator and metarepresentational mechanisms. Through a variety of arguments we try to show that explanation by recourse to these mechanisms is inadequate. We (...) conclude by suggesting that one possible reason for the failure of the functionalist approaches is that they begin from the assumption that thought is a form a of willed action. (shrink)

Overview of some of the key philosophical problems encountered making sense of the notion of "subjective time", with a focus on the experience of duration. The paper unpacks some of the assumptions behind an intuitive picture of duration experience I call the "simple flow" view, highlighting the availability of alternative models. It then considers a number of obstacles to providing an account of the individuation of subjective features of duration experience.

The notion of domain specificity plays a central role in some of the most important debates in cognitive science. Yet, despite the widespread reliance on domain specificity in recent theorizing in cognitive science, this notion remains elusive. Critics have claimed that the notion of domain specificity can't bear the theoretical weight that has been put on it and that it should be abandoned. Even its most steadfast proponents have highlighted puzzles and tensions that arise once one tries to go beyond (...) an initial intuitive sketch of what domain specificity involves. In this paper, we address these concerns head on by developing an account of what it means for a cognitive mechanism to be domain specific that overcomes the obstacles that have made domain specificity seem so problematic. We then apply this understanding of domain specificity to one of the key debates that it has figured prominently in—the rationalism-empiricism debate concerning the origins of cognitive traits—and introduce several related theoretical notions that work alongside domain specificity in helping to clarify what makes a view more (or less) rationalist. This example illustrates how the notion of domain specificity can, and should, continue to play a central role in ongoing debates in cognitive science. (shrink)

A major obstacle to the acceptance of materialist theories of the mind is the problem of sensory consciousness. How could a physical brain produce conscious sensory states that exhibit the rich and luxurious qualities of red velvet, a Mozart concerto or fresh-brewed coffee? A full answer to this question requires two different sorts of theory. The first sort considers what all these conscious sensory states have in common, by virtue of being conscious as opposed to unconscious states. The second (...) sort considers what distinguishes conscious sensory-states from each other, for example, how the qualities in a conscious sensory state of red velvet differ from those of a Mozart concerto. I propose a theory of the first sort, that is, an explanation of the distinction between conscious and unconscious sensory states. ;According to the second sense theory, conscious sensory states are coordinated sensory representations of the present moment produced by a second sense. Three elements are necessary and jointly sufficient for sensory consciousness. Sensory representations must be coordinated toward action in the world. The representations included in the content of a conscious sensory state are those that will aid the creature in assessing current environmental conditions according to the task at hand. Conscious sensory states represent states of affairs as occurring at the present moment. In other words, sensory consciousness is constituted by the coordination of sensory representations into a representation of what is happening 'now.' The mechanism responsible for coordinating sensory representations into conscious sensory states is the second sense. A second sense mechanism explains how some sensory representations become coordinated into a conscious sensory state while others remain unconscious. ;In addition to providing an explanation of sensory consciousness, the second sense theory is nicely suited to a Gibsonian account of subjectivity, whereby information about the subject is specified simultaneously in perception with information about the object. I argue that the subject, at its most bare, is the locus of an egocentric map, the zero point of a coordinate system which specifies objects according to here. (shrink)

Taking its cue from François Bernier’s Voyages and focusing on the assumptions that stand in the background of Immanuel Kant’s view of the encounter between Christianity and Hinduism, this text endeavors to bring to light the theoretical framework that shaped the dialogue between the West and the East since the 18th century. The author’s contention is that the way that Western philosophy has tended to conceive of universal values has been one of the fundamental obstacles that has hindered a genuine (...) cross-cultural conversation in this sense.

After introducing the concept of compressed sensing as a complementary measurement mode to the classical Shannon-Nyquist approach, I discuss some of the drivers, potential challenges and obstacles to its implementation. I end with a speculative attempt to embed compressed sensing as an enabling methodology within the emergence of data-driven discovery. As a consequence I predict the growth of non-nomological sciences where heuristic correlations will find applications but often bypass conventional pure basic and use-inspired basic research stages due to the lack (...) of verifiable hypotheses.

Acidity, generated in hypoxia or hypermetabolic states, perturbs homeostasis and is a feature of solid tumors. That acid peripherally disperses lysosomes is a three‐decade‐old observation, yet one little understood or appreciated. However, recent work has recognized the inhibitory impact this spatial redistribution has on mechanistic target of rapamycin complex 1 (mTORC1), a key regulator of metabolism. This finding argues for a paradigm shift in localization of mTORC1 activator Ras homolog enriched in brain (RHEB), a conclusion several others have now independently (...) reached. Thus, mTORC1, known to sense amino acids, mitogens, and energy to restrict biosynthesis to times of adequate resources, also senses pH and, via dampened mTOR‐governed synthesis of clock proteins, regulates the circadian clock to achieve concerted responses to metabolic stress. While this may allow cancer to endure metabolic deprivation, immune cell mTOR signaling likewise exhibits pH sensitivity, suggesting that suppression of antitumor immune function by solid tumor acidity may additionally fuel cancers, an obstacle potentially reversible through therapeutic pH manipulation.

Making sense of why something succeeded or failed is central to scientific practice: it provides an interpretation of what happened, i.e. an hypothesized explanation for the results, that informs scientists’ deliberations over their next steps. In philosophy, the realism debate has dominated the project of making sense of scientists’ success and failure claims, restricting its focus to whether truth or reliability best explain science’s most secure successes. Our aim, in contrast, will be to expand and advance the practice-oriented (...) project sketched by Arthur Fine in his work on the Natural Ontological Attitude. An important obstacle to articulating a positive program, we suggest, has been overlooking how scientists adopt standardized rules and procedures in order to define and operationalize meanings for success and failure relative to their situated goals. To help fill this gap, we introduce two new ideas, design specifications and track records, and show how they advance our ability to make sense of scientific modeling practices while maintaining a deflationary stance toward the realism debate.

The present article is a primary introduction to the semi-structured interviewing method SMILE_PH, an acronym for Sense-Making Interviews Looking at Elements of Philosophical Health. Beyond grounding this new methodology theoretically (a work that is started here but will in the future necessitate several developments), the main motivation here is pragmatic: to provide the recent philosophical health movement with a testable method and show that philosophically-oriented interviews are possible in a manner that can be reproduced, compared, tested and used systematically (...) with a population that has received no training in philosophy. The SMILE_PH approach was conceived by the author during an ethically approved pilot study focused on the philosophy of life of persons living with spinal cord injury (SCI), with the intention of rectifying the epistemic obstacles generated by rationalist, Socratic or unstructured ways of in-depth interviewing. The six-step structure of the method is also inspired by hundreds of individual dialogue sessions with philosophical counselees, led by the author between 2018 and 2022: the SMILE_PH method progressively gathers phenomenological data about 1 – our bodily sense, 2 – our sense of self, 3 – our sense of belonging, 4 – our sense of the possible, 5 – our sense of purpose and 6 – our philosophical sense.

The article considers the problem of navigating mobile robots and finding the best way to the goal in real-time in a space surrounded by unknown objects. The motor actions of the robot must be defined and adapted to changes in the environment. When using only laser scanners on mobile work, objects above or below the lasers' level will remain obstacles to the robot. Current algorithms and principles of navigation are considered. Extended the existing real-time interference detection system using lasers by (...) adding a camera that calculates the length of objects. The new system has been successfully implemented and tested in a mobile robot, ensuring the passage of the road providing collision-free paths. The obtained simulation results are presented in the article. The existing problems of navigation of mobile robots, which are moving in the particular area from their position to the specified destination on the map, were investigated. The current problem is the inability to spot objects that are not on the same level as the mobile robot's lasers. Moreover, the task is complicated when you need to recognize such objects while the robot is moving in real time. The current algorithms and principles of navigation given by previous research and publications are analyzed. As a result of the work, the existing system of recognition and avoidance of obstacles was expanded. Prior to that, the system used only odometry and information obtained from laser scanners, without obtaining data from other sources of environmental information. The idea of development was to use a camera, which was already part of the components of the researched mobile robot. It has become possible to generate a pointcloud relative to the environment, using a depth sensing camera to calculate the distance to objects. Because the density of the received data in the form of a pointcloud is too high for further processing, a downsample VoxelGrid filter was used, which reduces the density of the point cloud. VoxelGrid belongs to the PCL library. Another problem was the removal of information about unnecessary objects in the camera's field of view. These include the floor, ceiling, parts of the robot. The PassThrough filter from the PCL library was used to solve this problem. The next step is to process the filtered data using OctoMap. As a result, an octree is generated. A top-down projection is created from the octree generated in the previous step. The resulting projection must be processed and converted into polygonal obstacles. Only then they will be marked by teb_local_planner as obstacles. The developed system was successfully implemented and tested both in the Gazebo simulation and in the researche mobile robot. The path with obstacles will be completed without collisions. The paper presents the obtained test results. (shrink)

Philosophers have had trouble defending the common sense view that it is permissible to impose significant cost on an innocent person who is about to harm you to prevent the harm from occurring. In this paper, I argue that such harm can be justified if one pays attention to the moral significance of imposing a cost on others. The constraint against harming people who give rise to cost by their presence or movements is weaker than the constraint against harming (...) bystanders. Moreover, I argue that people who give rise to cost have a duty to take on some of that cost to help protect the person under threat. (shrink)

Psychological research has revealed that there is a strong tendency for people to believe that they have a ‘true self’, and to believe that this true self is inherently morally good. This would seemingly be very good news for virtue theorists, since this may help to promote virtue development. While there are some obvious benefits to people having morality intrinsically tied to their sense of self, in this paper I want to suggest instead that there may also be some (...) significant drawbacks, especially when it comes to motivating virtue development and moral improvement. In part this stems from people’s belief in their own inherent moral goodness being merely assumed (as part of one’s core identity), rather than earned (say through reliably good moral behavior). This disconnection between identity and behavior can result in attempts to reinforce one’s identity as morally good, at the expense of virtuous behavior or self-improvement. (shrink)

This paper focuses on Paul of Venice’s realist theory of direct knowledge. In the second half of the 13th century human knowledge was standardly viewed as a process of abstraction enabling the human intellect to grasp the essences of corporeal things, regardless of the matter in which they are embodied. This process was achieved thanks to the mediation of mental entities (species intelligibiles) representing the dematerialised objects in the intellect. By the late 13th and early 14th centuries, however, some authors (...) began to regard this account as unsatisfactory. These authors held that assuming the existence of mediating species (considered themselves as objects of knowledge) amounts to thinking that between ourselves and the world there is a barrier preventing us from acquiring knowledge of reality in itself. Paul of Venice is aware of the sceptical accusations made against the theory of species in the 13th and 14th centuries. Nevertheless, he is a firm advocate of the existence of species. He claims that knowledge, despite coming about through species, is not indirect. Quite the contrary: we have immediate access to reality, and the individual objects that constitute it, precisely because our senses (which are purely passive) receive impressions direct from outside, thanks to species. He points out that species are not object of knowledge. They are not known at all during the cognitive process, as they are a mere means (a mechanical means, so to say), not an image nor a representation of anything, and therefore they are no obstacle between ourselves and the world. Thus, we are able to know reality exactly as it is in itself and, under ordinary conditions, our perceptions are practically infallible and cannot produce false knowledge. (shrink)

Collective apologies on behalf of governments to historically mistreated minorities have become more common. It is unclear, however, how we should respond to these apologies and other practices that invoke collective responsibility for oppression (chapter 1). I review the current literature on collective responsibility to better understand the obstacles facing an account of collective responsibility for oppression (chapter 2). I then argue that we can make sense of these practices by holding powerful organized collectives (chapter 3) and privileged disorganized (...) collectives (chapter 4) responsible for oppression. These practices then can be what I call “morally legitimate” if they are confessions of self-blame, and this self-blame contains an element of collective-self protest (chapter 5). (shrink)

This paper is a critique of certain arguments given by the Milindapanha and Jay Garfield for the conventional nature of reality or existence. These arguments are of interest in their own right. They also are significant if they are presumed to attack an obstacle we all face in achieving non-attachment, namely, our belief in the inherent or substantial existence of ourselves and the familiar objects of our world. The arguments turn on a distinction between these objects, and some other (...) way of conceiving of them, in terms of which their conventional existence becomes apparent. After the distinction and the arguments that depend on it are shown to be problematic, the paper concludes with some reflections on the doctrine of skillful means and its applicability to Buddhist philosophical argument.

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods. This adjustment process is driven by a continuously updated estimate of the rate of (...) forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact-learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

The fields of machine learning (ML) and cognitive science have developed complementary approaches to computationally modeling human behavior. ML's primary concern is maximizing prediction accuracy; cognitive science's primary concern is explaining the underlying mechanisms. Cross-talk between these disciplines is limited, likely because the tasks and goals usually differ. The domain of e-learning and knowledge acquisition constitutes a fruitful intersection for the two fields’ methodologies to be integrated because accurately tracking learning and forgetting over time and predicting future performance based on (...) learning histories are central to developing effective, personalized learning tools. Here, we show how a state-of-the-art ML model can be enhanced by incorporating insights from a cognitive model of human memory. This was done by exploiting the predictive performance equation's (PPE) narrow but highly specialized domain knowledge with regard to the temporal dynamics of learning and forgetting. Specifically, the PPE was used to engineer timing-related input features for a gradient-boosted decision trees (GBDT) model. The resulting PPE-enhanced GBDT outperformed the default GBDT, especially under conditions in which limited data were available for training. Results suggest that integrating cognitive and ML models could be particularly productive if the available data are too high-dimensional to be explained by a cognitive model but not sufficiently large to effectively train a modern ML algorithm. Here, the cognitive model's insights pertaining to only one aspect of the data were enough to jump-start the ML model's ability to make predictions—a finding that holds promise for future explorations.

The aim of this study was to assess attitudes of intensive care nurses to selected ethical issues related to end-of-life decisions in paediatric intensive care units. A self-administered questionnaire was distributed in 2005 to intensive care nurses at two different scientific occasions in Turkey. Of the 155 intensive care nurse participants, 98% were women. Fifty-three percent of these had intensive care experience of more than four years. Most of the nurses failed to agree about withholding (65%) or withdrawing (60%) futile (...) treatment. In addition, 68% agreed that intravenous nutrition must continue at all costs. In futile treatment cases, the nurses tended to leave the decision to parents or act maternalistically. The results showed that intensive care nurses could ignore essential ethical duties in end-of-life care. We suggest that it is necessary to educate Turkish intensive care nurses about ethical issues at the end of life. (shrink)

The parameters governing our behavior are in constant flux, and capturing these dynamics in cognitive models remains a challenge. We demonstrate how a mapping between ACT‐R's model of declarative memory and the linear ballistic accumulator enables efficient estimation of memory parameters from data. The resulting estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals.

The parameters governing our behavior are in constant flux. Accurately capturing these dynamics in cognitive models poses a challenge to modelers. Here, we demonstrate a mapping of ACT-R's declarative memory onto the linear ballistic accumulator (LBA), a mathematical model describing a competition between evidence accumulation processes. We show that this mapping provides a method for inferring individual ACT-R parameters without requiring the modeler to build and fit an entire ACT-R model. Existing parameter estimation methods for the LBA can be used, (...) instead of the computationally expensive parameter sweeps that are traditionally done. We conduct a parameter recovery study to confirm that the LBA can recover ACT-R parameters from simulated data. Then, as a proof of concept, we use the LBA to estimate ACT-R parameters from an empirical dataset. The resulting parameter estimates provide a cognitively meaningful explanation for observed differences in behavior over time and between individuals. In addition, we find that the mapping between ACT-R and LBA lends a more concrete interpretation to ACT-R's latency factor parameter, namely as a measure of response caution. This work contributes to a growing movement towards integrating formal modeling approaches in cognitive science. (shrink)

It is always possible to construct a real function φ, given random quantities X and Y with continuous distribution functions F and G, respectively, in such a way that φ(X) and φ(Y), also random quantities, have both the same distribution function, say H. This result of De Finetti introduces an alternative way to somehow describe the `opinion' of a group of experts about a continuous random quantity by the construction of Fields of coincidence of opinions (FCO). A Field of coincidence (...) of opinions is a finite union of intervals where the opinions of the experts coincide with respect to that quantity of interest. We speculate on (dis)advantages of Fields of Opinion compared to usual `probability' measures of a group and on their relation with a continuous version of the well-known Allais' paradox. (shrink)

The sense of agency is typically defined as the experience of controlling one’s own actions, and through them, changes in the external environment. It is often assumed that this experience is a single, unified construct that can be experimentally manipulated and measured in a variety of ways. In this article, we challenge this assumption. We argue that we should acknowledge four possible agency-related psychological constructs. Having a clear grasp of the possible constructs is important since experimental procedures are only (...) able to target some but not all the possible constructs. The unacknowledged misalignment of the possible constructs of a sense of agency and the experimental procedures is a major theoretical and methodological obstacle to studying the sense of agency. Only if we recognize the nature of this obstacle will we be able to design the experimental paradigms that would enable us to study the responsible computational mechanisms. (shrink)

It is well known that Kant distinguishes between two kinds of self-consciousness: transcendental apperception and empirical apperception (or, approximately, inner sense). However, Kant sometimes claims that “I think,” the general expression of transcendental apperception, expresses an indeterminate empirical inner intuition (IEI), which differs in crucial ways from the empirical inner intuition produced by inner sense. Such claims undermine Kant’s conceptual framework and constitute a recalcitrant obstacle to understanding his theory of self-consciousness. This paper analyzes the relevant passages, (...) evaluates the major interpretations of IEI, revisits the notion of pure apperception, and proposes an alternative reading: IEI is a ubiquitous, nonfocal, “obscure,” and empirical inner intuition that is built into all nonintrospective conscious states. This reading can successfully account for the peculiarities of IEI, resolving a major mystery in Kant’s theory of self-consciousness. (shrink)

Disabled people face obstacles to participation in epistemic communities that would be beneficial for making sense of our experiences and are susceptible to epistemic oppression. Knowledge and skills grounded in disabled people's experiences are treated as unintelligible within an ableist hermeneutic, specifically, the dominant conception of disability as lack. My discussion will focus on a few types of epistemic oppression—willful hermeneutical ignorance, epistemic exploitation, and epistemic imperialism—as they manifest in some bioethicists’ claims about and interactions with disabled people. One (...) of the problems with the epistemic phenomena with which I am concerned is that they direct our skepticism regarding claims and justifications in the wrong direction. When we ought to be asking dominantly situated epistemic agents to justify their knowledge claims, our attention is instead directed toward skepticism regarding the accounts of marginally situated agents who are actually in a better position to know. I conclude by discussing disabled knowers’ responses to epistemic oppression, including articulating the epistemic harm they have undergone as well as ways of creating resistant ways of knowing.

Perceptual experiences justify beliefs—that much seems obvious. As Brewer puts it, “sense experiential states provide reasons for empirical beliefs” (this volume, xx). In Mind and World McDowell argues that we can get from this apparent platitude to the controversial claim that perceptual experiences have conceptual content: [W]e can coherently credit experiences with rational relations to judgement and belief, but only if we take it that spontaneity is already implicated in receptivity; that is, only if we take it that experiences (...) have conceptual content. (1994, 162) Brewer agrees. Their view is sometimes called conceptualism; nonconceptualism is the rival position, that experiences have nonconceptual content. One initial obstacle is understanding what the issue is. What is conceptual content, and how is it different from nonconceptual content? Section 1 of this paper explains two versions of each of the rival positions: state (non)conceptualism and content (non)conceptualism; the latter pair is the locus of the relevant dispute. Two prominent arguments for content nonconceptualism—the richness argument and the continuity argument—both fail (section 2). McDowell’s and Brewer’s epistemological defenses of content conceptualism are also faulty (section 3). Section 4 gives a more simple-minded case for conceptualism; finally, some reasons are given for rejecting the claim—on one natural interpretation—that experiences justify beliefs. (shrink)

ABSTRACT What are the obstacles to believing that narratives can argue? How can we be assured that narratives argue well? This article will explore major objections to accounts of narrative argument and literary truth, and explore a theory of narrative reasoning that emphasizes identification as a vital part of argument. In exploring the account of narrative offered by Walter Fisher in light of concerns with narrative in rhetorical studies and philosophy, I explicate a renewed sense of identification and narrative (...) reasoning that can meet many of these objections to giving narrative a role in human communication and argument. Of particular interest are the resources available in narratives for active identification by an auditor or reader as good reasons for action or belief in their own extratextual activities. (shrink)

Consciousness and Mind presents David Rosenthal's influential work on the nature of consciousness. Central to that work is Rosenthal's higher-order-thought theory of consciousness, according to which a sensation, thought, or other mental state is conscious if one has a higher-order thought that one is in that state. The first four essays develop various aspects of that theory. The next three essays present Rosenthal's homomorphism theory of mental qualities and qualitative consciousness, and show how that theory fits with and helps sustain (...) the HOT theory. A crucial feature of homomorphism theory is that it individuates and taxonomizes mental qualities independently of the way we're conscious of them, and indeed independently of our being conscious of them at all. So the theory accommodates the qualitative character not only of conscious sensations and perceptions, but also of those which fall outside our stream of consciousness. Rosenthal argues that, because this account of mental qualities makes no appeal to consciousness, it enables us to dispel such traditional quandaries as the alleged conceivability of undetectable quality inversion, and to disarm various apparent obstacles to explaining qualitative consciousness and understanding its nature. Six further essays build on the HOT theory to explain various important features of consciousness, among them the complex connections that hold in humans between consciousness and speech, the self-interpretative aspect of consciousness, and the compelling sense we have that consciousness is unified. Two of the essays, one an extended treatment of homomorphism theory, appear here for the first time. There is also a substantive introduction, which draws out the connections between the essays and highlights their implications. (shrink)

We discuss the idea that superpositions in quantum mechanics may involve contradictions or contradictory properties. A state of superposition such as the one comprised in the famous Schrödinger’s cat, for instance, is sometimes said to attribute contradictory properties to the cat: being dead and alive at the same time. If that were the case, we would be facing a revolution in logic and science, since we would have one of our greatest scientific achievements showing that real contradictions exist.We analyze that (...) claim by employing the traditional square of opposition.We suggest that it is difficult to make sense of the idea of contradiction in the case of quantum superpositions. From a metaphysical point of view the suggestion also faces obstacles, and we present some of them. (shrink)

The purpose of this study is exposition on the themes of method and mysticism in the work of Simone Weil. Nearly a decade before the onset of her first mystical experience, Weil developed a method to be rigorously applied in daily philosophical reflection. She outlines this method in her dissertation on Descartes (1929-1930). I examine the question of how Weil applied method to philosophical reflection on her mystical experiences (onset 1938-1939). I analyze Weil’s mystical experiences as a type of transformative (...) experience in L. A. Paul’s strict sense of the term. On Paul’s view, an experience is transformative if it is both epistemically and personally transformative. An experience is epistemically transformative if the only way to know what it is like to have it is to have it yourself. An experience is personally transformative if it changes your point of view, including your core preferences (Paul, 2014). I present a thought experiment and textual evidence to motivate the claim that Weil’s mystical experiences meet Paul’s conditions for transformative experience. I then propose two epistemological facts that can be revealed by philosophical reflection on mystical experience. First, it is possible to read meaning erroneously in the appearances of things. Second, it is possible to come to hold to the certainty of a conviction for reasons that elude the intellect. My findings suggest that Weil’s late views on philosophy accommodate these two epistemological constraints, thereby demonstrating a possible connection between Weil’s mystical experiences and her mature views on the nature, scope, and proper method of philosophy. However, my preliminary findings also suggest that Weil’s early work on method may have anticipated these epistemological obstacles prior to the onset of her first mystical experience. Thus, further exposition of Weil’s method is needed to support or elucidate the claim (Rozelle-Stone and Davis, 2021) that Weil’s epistemology underwent significant changes because of her mystical experiences.

Good reasons to forgive typically divorce act from agent so that there is nothing in the agent to be forgiven. Forgiving on the basis of good reasons that show the wrongdoer deserves forgiveness is thus minimalist because nonelective. Genuine, or aspirational, forgiveness requires forgiving agents for unexcused, unjustified, and unrepented wrongdoing. The primary obstacle to aspirational forgiveness is that we cannot make sense of persons choosing evil. This essay suggests a way of rendering the choice of evil intelligible (...) and thus of achieving aspirational forgiveness. (shrink)

This essay articulates obstacles to an interpretation of the whole proper to Plato’s philosophy that are rooted in the general methodical principle of traditional hermeneutics, and then addresses them by a novel hermeneutic application of Husserl’s transcendental and eidetic reductions. This application involves disclosing the transcendental phenomena of the texts of Plato’s dialogues on the basis of the former and articulating their phenomenological essence in accord with the latter. A meta-hermeneutical argument for what Plato himself might have thought is then (...) ventured, which takes as its point of departure both the transcendental phenomena of his texts and Aristotle’s report that eide for him were in some sense arithmoi.

Henry More argues that materialism cannot account for cases where a single subject or perceiver has multiple perceptions simultaneously. Since we clearly do have multiple perceptions at the same time--for example, when we see, hear, and smell simultaneously--More concludes that we are not wholly material. In response to More's argument, Margaret Cavendish adopts a two-fold strategy. First, she argues that there is no general obstacle to mental unification in her version of materialism. Second, Cavendish appeals to the mind or (...) rational matter--terms she often uses interchangeably—to explain the integration of sensory input from multiple senses. When the mind integrates perceptions across modalities, the different parts of rational matter share their knowledge so that they all come to perceive alike. When rational parts successfully communicate their knowledge, each part knows what all the others know. They pool their knowledge; they perceive alike. Thus, when someone hears, sees, and tastes, each part of her mind hears, sees, and tastes alike, in parallel and in unison. The Cavendishian mind, in short, approximates simplicity by achieving uniformity or homogeneity of perceptions across its parts. (shrink)

Two arguments apparently support the thesis that collective identity presupposes an Other: the recognition argument, according to which seeing myself as a self requires recognition by an other whom I also recognize as a self (Hegel); and the dialogic argument, according to which my sense of self can only develop dialogically (Taylor). But applying these arguments to collective identity involves a compositional fallacy. Two modern ideologies mask the particularist thesis’s falsehood. The ideology of indivisible state sovereignty makes sovereignty as (...) such appear particularistic by fusing “internal” with “external” sovereignty; nationalism imagines national identity as particularistic by linking it to sovereignty. But the concatenation of internal sovereignty, external sovereignty, and nation is contingent. Schmitt’s thesis that “the political” presupposes an other conflates internal and external sovereignty, while Mouffe’s neo-Schmittianism conflates difference (Derrida) with alterity. A shared global identity may face many obstacles, but metaphysical impossibility and conceptual confusion are not among them. (shrink)

This is not "another collection of contributions on a traditional subject." Even more than we dared to expect during the preparatory stages, the papers in this volume prove that our thinking about science has taken a new turn and has reached a new stage. The progressive destruction of the received view has been a fascinating and healthy experience. At present, the period of destruction is over. A richer and more equilibrated analysis of a number of problems is possible and is (...) being cru'ried out. In this sense, this book comes right on time. We owe a lot to the scholars of the Kuhnian period. They not only did away with obstacles, but in several respects instigated a shift in attention that changed history and philosophy of science in a irreversible way. A c1earcut example - we borrow it from the paper by Risto Hilpinen - concerns the study of science as a process, Rnd not only as a result. Moreover, they apparently reached several lasting results, e.g., concerning the tremendous impact of theoretical conceptions on empirical data. Apart from baffling people for several decades, this insight rules out an other return to simple-minded empiricism in the future. (shrink)

Might traditional Chinese thought regarding creativity not just influence, but also enrich, contemporary European thought about the same? Moreover, is it possible that traditional Chinese thought regarding creativity might enrich contemporary thought both in a more broad, holistic sense, and more specifically regarding the nature and role of creativity as it pertains to scientific inquiry? In this paper, I elucidate why the answer to these questions is: yes. I explain in detail a classical Chinese conception of creativity rooted in (...) Zhuangist philosophy and which centrally involves spontaneity engendered by embracing yóu遊, or “wandering”, rather than novelty or originality. I then illustrate how this conception of creativity can be used to enrich contemporary thought regarding the nature and role of creativity both in general and as it pertains to scientific inquiry in particular, as well as how to engender creativity, by arguing that it might allow us to: i) more easily remove what is frequently an obstacle to creativity, and; ii) better understand creative agents as being more intimately connected with, and as processes within and products of, their environments. Finally, I conclude by briefly remarking on how exploring various cultural perspectives on creativity promises to help us to better comprehend and promote creativity, by encouraging us to become more creative about creativity itself.

Everyone has heard the claim, "Correlation does not imply causation." What might sound like a reasonable dictum metastasized in the twentieth century into one of science's biggest obstacles, as a legion of researchers became unwilling to make the claim that one thing could cause another. Even two decades ago, asking a statistician a question like "Was it the aspirin that stopped my headache?" would have been like asking if he believed in voodoo, or at best a topic for conversation at (...) a cocktail party rather than a legitimate target of scientific inquiry. Scientists were allowed to posit only that the probability that one thing was associated with another. This all changed with Judea Pearl, whose work on causality was not just a victory for common sense, but a revolution in the study of the world. (shrink)
