The electric activities of cortical pyramidal neurons are supported by structurally stable, morphologically complex axo-dendritic trees. Anatomical differences between axons and dendrites in regard to their length or caliber reflect the underlying functional specializations, for input or output of neural information, respectively. For a proper assessment of the computational capacity of pyramidal neurons, we have analyzed an extensive dataset of three-dimensional digital reconstructions from the NeuroMorphoOrg database, and quantified basic dendritic or axonal morphometric measures in different regions and layers of (...) the mouse, rat or human cerebral cortex. Physical estimates of the total number and type of ions involved in neuronal electric spiking based on the obtained morphometric data, combined with energetics of neurotransmitter release and signaling fueled by glucose consumed by the active brain, support highly efficient cerebral computation performed at the thermodynamically allowed Landauer limit for implementation of irreversible logical operations. Individual proton tunneling events in voltage-sensing S4 protein alpha-helices of Na+, K+ or Ca2+ ion channels are ideally suited to serve as single Landauer elementary logical operations that are then amplified by selective ionic currents traversing the open channel pores. This miniaturization of computational gating allows the execution of over 1.2 zetta logical operations per second in the human cerebral cortex without combusting the brain by the released heat.

In his book, The Grounds of Moral Judgment, Russell Grice argues for a thesis he calls "the contract ground thesis," which connects the interest of members of a group in making a contract to the existence of an obligation and reason to abide by that contract. This thesis has been challenged by Jesse Kalin and subsequently defended by Grice. We show that Grice's defense fails--the contract ground thesis is without justification.

The idea that there could be spatially extended mereological simples has recently been defended by a number of metaphysicians (Markosian 1998, 2004; Simons 2004; Parsons (2000) also takes the idea seriously). Peter Simons (2004) goes further, arguing not only that spatially extended mereological simples (henceforth just extended simples) are possible, but that it is more plausible that our world is composed of such simples, than that it is composed of either point-sized simples, or of atomless gunk. The difficulty for these (...) views lies in explaining why it is that the various sub-volumes of space occupied by such simples, are not occupied by proper parts of those simples. Intuitively at least, many of us find compelling the idea that spatially extended objects have proper parts at every sub-volume of the region they occupy. It seems that the defender of extended simples must reject a seemingly plausible claim, what Simons calls the geometric correspondence principle (GCP): that any (spatially) extended object has parts that correspond to the parts of the region that it occupies (Simons 2004: 371). We disagree. We think that GCP is a plausible principle. We also think it is plausible that our world is composed of extended simples. We reconcile these two notions by two means. On the one hand we pay closer attention to the physics of our world. On the other hand, we consider what happens when our concept of something—in this case space—contains elements not all of which are realized in anything, but instead key components are realized in different features of the world.

Davis called for “extreme caution” in the use of non-invasive brain stimulation to treat neurological disorders in children, due to gaps in scientific knowledge. We are sympathetic to his position. However, we must also address the ethical implications of applying this technology to minors. Compensatory trade-offs associated with NIBS present a challenge to its use in children, insofar as these trade-offs have the effect of limiting the child’s future options. The distinction between treatment and enhancement has some normative force here. (...) As the intervention moves away from being a treatment toward being an enhancement—and thus toward a more uncertain weighing of the benefits, risks, and costs—considerations of the child’s best interests diminish, and the need to protect the child’s autonomy looms larger. NIBS for enhancement involving trade-offs should therefore be delayed, if possible, until the child reaches a state of maturity and can make an informed, personal decision. NIBS for treatment, by contrast, is permissible insofar as it can be shown to be at least as safe and effective as currently approved treatments, which are themselves justified on a best interests standard.

In this paper, I want to focus not on the problems that I believe may threaten Kant’s account of the highest good, but instead on those that I believe threaten the majority of the interpretive reconstructions attempted by commentators and thus prevent the emergence of a consensus in the near future. My goal is to set forth exactly four problems to which I believe any successful interpretation or reconstruction of Kant’s account of the highest good will have to provide substantive (...) solutions and, in doing so, either break new theoretical ground or at least provide a more comprehensive methodology for sorting through the texts.

Face-to-face learning engagement has been suspended due to the health crisis that affected the whole world. This led to the adaptation of modular distance learning to continue delivering quality education. As the transition continues, its effectiveness has been frequently assessed. The key purpose of this study is to determine the relationship between the level of implementation of modular distance learning and English Writing Proficiency among the senior high school students in Saint Joseph College Maasin City School year 2021-2022. The study (...) employed a descriptive correlational design with 39 purposively chosen respondents. The main tools used in gathering the data were questionnaires, learning modules, and rubrics. Findings revealed that the implementation of modular distance learning (MDL) has an overall very satisfactory rating based on the perception of the students. The student’s perception of the implementation of modular distance learning and their writing proficiency is significantly related. Moreover, it revealed that students had difficulties in finding supplementary learning materials and educational support from home. The researcher recommends a set of guidelines for the successful and effective implementation of modular distance learning as the output of the study. (shrink)

Citizen Satisfaction Index System (CSIS) was used to assess the delivery of support to education initiatives in the municipality of Banga, Aklan, Philippines. The samples were determined using multiple application of stratified random sampling approach. In accordance with the Philippine Statistical Authority's Data on Census Population and Housing for 2015, barangays having a bigger share of the population contributed more respondents to the 150 targeted participants. Following the inclusion criteria, the probability respondents were chosen using the Kish Grid. Pre-numbered questionnaires (...) were distributed, with odd numbers targeting male responders and even numbers targeting females. The following criteria were used to evaluate the respondents' assessments: awareness, availment of the program/service, satisfaction, and need for action. Furthermore, interviews were conducted to better understand and investigate the respondents' thoughts, behavior, and perspectives. The reasons for their reaction were also obtained. The data was provided in percentage as well as frequency distributions. The study inferred that awareness on alternative learning system and/or special education program should be improved since it is the only program that attained low rating for awareness. Most of the residents were not able to avail education programs because they have no household member who attends school. Majority of the respondents who availed the services were satisfied. However, scholarship and other assistance programs to students may be enhanced to improve service delivery. It is highly recommended by the citizens to improve accessibility to scholarship programs and other forms of financial assistance to students. (shrink)

The publication of this volume allows us to entertain feelings of contentment and confidence that this objective of the project has been accomplished. (shrink)

This paper defends the Principle of Sufficient Reason, taking Baumgarten as its guide. The primary aim is not to vindicate the principle, but rather to explore the kinds of resources Baumgarten originally thought sufficient to justify the PSR against its early opponents. The paper also considers Baumgarten’s possible responses to Kant’s pre-Critical objections to the proof of the PSR. The paper finds that Baumgarten possesses reasonable responses to all these objections. While the paper notes that in the absence of a (...) response to Kant’s Critical discussion of the PSR, this result does not vindicate the principle, it shows how this discussion provides a deeper understanding of what, according to Baumgarten, the PSR really assumes and intends, and prepares the way for a more responsible discussion of Kant’s critical objections to Baumgarten’s supposed proof.

One of the important questions discussed by philosophers of technology has to do with the moral significance of artefacts in human life. While many philosophers agree that artefacts do have moral significance attached to them, opinions vary as to how it is to be construed. In this paper we deal with the approach of the influential Dutch philosopher of technology Peter Paul Verbeek. He criticizes traditional ethical theories for assuming that whatever relevancy artefacts have for morality is entirely dependent on (...) human beings, since artefacts are mere passive instruments of human agency. In contrast, he develops a view of moral agency that includes artefacts and that ascribes moral agency to human-technology hybrids rather than to humans as such. The goal of this paper is to elucidate Verbeek’s account of moral agency and evaluate it. We also deal with his views on post phenomenology and mediation underlying this account. Although the general gist of our paper is expository, we point out to several problems for Verbeek’s account. (shrink)

The Fifth Element (1997) is a French science-fiction film in English, directed and co-written by Luc Besson. The title and the plot of the film refer to a central notion of Greek philosophy, that is, pemptousia, or quintessence. Pre-Socratic philosophers such as Thales, Anaxagoras, Anaximenes and others, were convinced that all natural beings – in fact, nature itself – consist in four primary imperishable elements or essences (ousiai), i.e., fire, earth, water, and air. To these four, Aristotle added aether, a (...) fifth essence (pemptousia). The introduction of aether gave birth to a great tradition in late Antique and Medieval philosophy, and eventually it came to signify not an additional primary element, but the core-essence of all beings, their fundamental ontological structure. Besson’s film draws its inspiration on this philosophical tradition but its cinematographic rendering of the concept of Quintessence is typical of the contemporaneous views on the core characteristics of matters. The modernity that stimulates the film is equally anti-transcendentalist and anti-essentialist. Thus, the fifth element of the film is existentially personified and genderized making the traditional philosophical significance of the term to be adjusted by modernity in an immanent and temporal context where in addition aesthetics plays a crucial role.

Abstract: In this paper we argue that Robert Kane’s theory of free will cannot accommodate the possibility of a sinless individual who faces morally significant choices because a sinless agent cannot voluntarily accord value to an immoral desire, and we argue that Kane’s theory requires this. Since the Jesus of the historic Christian tradition is held to be sinless, we think Christians should reject Kane’s theory because it seems irreconcilable with historic Christian Christology. We consider two objections to our argument (...) and argue that both fail. (shrink)

Every day, television news operations have available dozens of video news releases (VNRs), public relations handout videos designed to mimic news formats. Electronic tracking indicates some of these VNRs are used. Critics typically assail VNRs on ethical grounds, that VNRs deceive audience members into thinking they are watching news gathered by reporters, rather than a promotional pitch. Using a snowball technique, the researchers presented survey respondents with authentic-looking local television news stories; 157 respondents evaluated three stories (out of nine). Some (...) stories used station-generated footage, some network, and some VNRs. Respondents were asked their best estimation of the source. The data indicated a real likelihood VNR deception is occurring. Two of the three VNRs deceived at least half the respondents. Respondents were incorrect an average of 46% of the time when attempting to identifying VNRs, compared to 29% incorrectly identifying network video and 20% incorrectly identifying locally shot video.

Because it is unclear how a nonconscious stimulus is cognitively processed, there is uncertainty concerning variables that modulate the processing. In this context recent findings of a set of neuroimaging experiments are important. These findings suggest that conscious and nonconscious stimuli activate same areas of the brain during performance of a similar task. Further, different areas are activated when a task is performed with or without awareness of processing. It appears that the neural network involved in cognitive processing depends on (...) the awareness of processing rather than awareness of perception. Since conscious and nonconscious cognitive processing use separate neural networks, each processing is modulated by different variables. Attention modulates most conscious cognitive processing and most, but not all, nonconscious processing is attention dependent. Nonconscious tasks that require attentional resources, with or without conscious awareness, are processed using the attention dependent system. Further, because attention dependent and attention independent tasks are processed by separate neural networks, the cognitive processing and modulating variables can be understood better if cognitive tasks are defined as attention dependent or attention independent, rather than conscious or nonconscious.

Social norms regulating carework and social reproduction tend to be inegalitarian. At the same time, such norms often play a crucial role when we plan our lives. How can we criticise objectionable practices while ensuring that people can organise their lives around meaningful and predictable rules? Gerald Gaus argues that only ‘publicly justified’ rules, rules that everyone would prefer over ‘blameless liberty,’ should be followed. In this paper, we uncover the inegalitarian implications of this feature of Gaus's framework. We show (...) that because a society without clear social norms for how social reproduction and care work ought to be organised would be so unattractive, inegalitarian rules would pass Gaus's test. They would pass this test since they would nevertheless be better than ‘blameless liberty.’ Those who are disproportionately burdened by a rule are faced with the daunting task of showing that they would be better off under no rule, instead of merely having to show that they would be better off with a different rule.

Philippine folk dances can be dated back as early as the pre-colonial period which inherited by our forefathers and passed through several generations of Filipinos. These traditional dances are considered treasures of our homeland for they depict the humble beginnings of our native countrymen and serve as a symbol of national identity. The study utilized focused ethnography and was limited on the documentation of the ethnic dance of Ayta Ambala’s tribe, their cultural values along with its cultural heritage situated at (...) Barangay Tubo-Tubo, Dinalupihan, Bataan which were considered unpublished, especially their respective dance patterns or movements. There were ten (10) informants involved in the study. Five (5) were key informants (KIs) who represent the emic perspective while five (5) were general informants (GIs) who represent the etic perspective of the paper. Findings revealed that Dances of Ayta Ambala include: Courtship (Sayaw Magligaw), Ceremonial (Sayaw Talipe), and Occupational (Sayaw Pangangaho). The said dances reflect different activities that are commong among the tribe. It also includes the historical background, costume, time signature, props, structural formation, dance steps, and figures. Although the values are not directly presented, these are still manifesting through the themes of their dances. Included in the cultural values are bravery, respect, and gratitude which are also part of the embodiment of different dances of Ayta Ambala. As observed, the other two emerging themes are also connected to the cultural heritage of Ayta Ambala. This means, their dances mirror their surroundings, their daily activities, and their identity as tribes. The emerging themes on cultural heritage are religious beliefs, courtships, and livelihood.

This chapter deals with the ways in which entrepreneurships driven by industrial design and the strategies for interconnecting design for innovation are articulated. In the first instance, current practices are recognized in order to analyze the different processes that entrepreneurial dynamics go through. This analysis is carried out from a systemic perspective, at three levels of abstraction: designer, entrepreneurship and ecosystem. The theoretical and conceptual framework will be structured based on the innovations driven by design, which occur around the designer, (...) his personal projects, and the possible interactions and singularities offered by living spaces. The objective of this work is to unravel the eventual relationships of the entrepreneurial designer in the ecosystem and to highlight the potential added by emerging connections, which allow for the projection of synergistic actions with other actors to create value(s). In this way, other possible views of the entrepreneurial process are provided, where the cultural and philosophical dimension that characterizes industrial designers allows them to achieve a higher quality of life, designing and producing collectively (in) their environment.

FDE is a logic that captures relevant entailment between implication-free formulae and admits of an intuitive informational interpretation as a 4-valued logic in which “a computer should think”. However, the logic is co-NP complete, and so an idealized model of how an agent can think. We address this issue by shifting to signed formulae where the signs express imprecise values associated with two distinct bipartitions of the set of standard 4 values. Thus, we present a proof system which consists of (...) linear operational rules and only two branching structural rules, the latter expressing a generalized rule of bivalence. This system naturally leads to defining an infinite hierarchy of tractable depth-bounded approximations to FDE. Namely, approximations in which the number of nested applications of the two branching rules is bounded. (shrink)

Over decades of teaching systematic theology at Union Theological Seminary (New York), Christopher Morse has set out to salvage “dogmatics” as a postmodern theological discipline that nevertheless retains a (more or less literal) construal of the apocalyptic gospel message. This article attempts to clarify this project in conversation with William James’ best-known work on religious belief.

Walter Wink is well-known for his exposition of what he has called “the third way” in Christian ethics, and his three-volume theological work expounding the nature of “the dominating powers that be” has left a lasting mark on Christian (post)liberalism -- not just in North America but elsewhere as well. However there is a vexing philosophical tension in Wink’s work, one that is even reflected in the fading of mainline Protestantism as a social force. This short piece was an early (...) effort to call attention to this challenge. (shrink)

Dewey’s view of art “as experience” takes the art object proper to be distinct from the physical artifact. The "work of art" is a label for a set of perceptual procedures in relation to a complex "situation" – one that is pregnant with vitality and saturated with “pervasive quality.” This qualitative trait is organic rather than merely mechanical in that the informed percipient’s sensibilities have already been sufficiently “funded” with a repertoire of emotionally imbued responses that culminate in a distinctive (...) “consummatory” experience. This account intends to combine classic notions of intrinsicality and instrumentality into a general story about art, which gets elevated into an honorific trait of human life generally -- all within a naturalistic framework.

Throughout his lengthy career Arthur Danto made significant and original contributions to action theory, historical narrative, and epistemology. He became best known however for his work as an art critic in the Nation, Artnews and elsewhere, and for his philosophical publications on art theory, beginning with his early (1964) article “The Artworld.” In fact, Danto’s views on art are emblematic of his overall philosophy: he managed to reconcile conflicting philosophical sensibilities without short-schrifting them. He appreciates both Hegel and postmodernism, but (...) his own philosophy is a good deal less radical than most postmodernisms in that he denies that philosophy is a radically historicist enterprise.

Mathematicians distinguish between proofs that explain their results and those that merely prove. This paper explores the nature of explanatory proofs, their role in mathematical practice, and some of the reasons why philosophers should care about them. Among the questions addressed are the following: what kinds of proofs are generally explanatory (or not)? What makes a proof explanatory? Do all mathematical explanations involve proof in an essential way? Are there really such things as explanatory proofs, and if so, how do (...) they relate to the sorts of explanation encountered in philosophy of science and metaphysics? (shrink)

We discuss potential biorisks from large language models (LLMs). AI assistants based on LLMs such as ChatGPT have been shown to significantly reduce barriers to entry for actors wishing to synthesize dangerous, potentially novel pathogens and chemical weapons. The harms from deploying such bioagents could be further magnified by AI-assisted misinformation. We endorse several policy responses to these dangers, including prerelease evaluations of biomedical AIs by subject-matter experts, enhanced surveillance and lab screening procedures, restrictions on AI training data, and access (...) controls on biomedical AI. We conclude with a suggestion about future research directions in bioethics. (shrink)

In this paper I explore Phyllis Rooney’s 2003 chapter, “Feminist Epistemology and Naturalized Epistemology: An Uneasy Alliance,” taking guidance from her critique of naturalized epistemology in pursuing my own analysis of another uneasy alliance: that between feminist epistemology and social epistemology. Investigating some of the background assumptions at work in prominent conceptions of social epistemology, I consider recent analyses of "epistemic bubbles" to ask how closely such analyses are aligned with ongoing research in feminist epistemology. I argue that critical feminist (...) insights in political philosophy are called for here, especially those that focus on multiple politically salient relationships and also emphasize practices of personal transformation as inseparably bound up with broader movements for social transformation. Insofar as feminist epistemology continues to carry another world in its heart, I argue that it will continue to rest uneasily with any effort to align it with—let alone subsume it within—the still emerging field of social epistemology.

In this paper, I develop and defend a new adverbial theory of perception. I first present a semantics for direct-object perceptual reports that treats their object positions as supplying adverbial modifiers, and I show how this semantics definitively solves the many-property problem for adverbialism. My solution is distinctive in that it articulates adverbialism from within a well-established formal semantic framework and ties adverbialism to a plausible semantics for perceptual reports in English. I then go on to present adverbialism as a (...) theory of the metaphysics of perception. The metaphysics I develop treats adverbial perception as a directed activity: it is an activity with success conditions. When perception is successful, the agent bears a relation to a concrete particular, but perception need not be successful; this allows perception to be fundamentally non-relational. The result is a novel formulation of adverbialism that eliminates the need for representational contents, but also treats successful and unsuccessful perceptual events as having a fundamental common factor.

Multidimensional adjectives are ubiquitous in natural language. An adjective F is multidimensional just in case whether F applies to an object or pair of objects depends on how those objects stand with respect to multiple underlying dimensions of F-ness. Developing a semantics for multidimensional adjectives requires us to address the problem of dimensional aggregation: how do the application conditions of an adjective F in its positive and comparative forms depend on its underlying dimensions? Here we develop a semantics for multidimensional (...) adjectives that incorporates aggregation functions. We then explore an analogy between dimensional aggregation and preference aggregation, bringing results from social choice theory to bear on the number and kind of aggregation functions that are admissible in a context. These results suggest that, for any given adjective, there will often be multiple aggregation functions admissible, meaning that multidimensional comparatives are often vague. (shrink)

Philosophers have rightly condemned lookism—that is, discrimination in favor of attractive people or against unattractive people—in education, the justice system, the workplace and elsewhere. Surprisingly, however, the almost universal preference for attractive romantic and sexual partners has rarely received serious ethical scrutiny. On its face, it’s unclear whether this is a form of discrimination we should reject or tolerate. I consider arguments for both views. On the one hand, a strong case can be made that preferring attractive partners is bad. (...) The idea is that choosing partners based on looks seems essentially similar to other objectionable forms of discrimination. (In particular, the preference for attractive partners is arguably both unfair and harmful to a significant degree.) One can try to resist this conclusion in several ways. I consider three possible replies. The first has to do with the possibility of controlling our partner preferences. The second pertains to attractiveness and “good genes”. The last attempts to link certain aspects of attractiveness to a prospective partner’s personality and values. I argue that the first two replies fail conclusively, while the third only amounts to a limited defense of a particular kind of attractiveness preference. So the idea that we should often avoid preferring attractive partners is compelling. (shrink)

People often fail to comply with the demands of morality. Partial compliance theory takes this noncompliance or its possibility into account in the formulation of moral requirements for people to comply with, or in the evaluation of people’s actions against those requirements. This chapter critically engages with recent work on partial compliance theory. It examines the relationship between noncompliance and injustice, assesses different ways of doing partial compliance theory, sketches the relationship between partial compliance theory and other central methodological debates (...) in moral and political philosophy, and considers whether it is reasonable to issue moral requirements without examining what would happen if everyone did their part.

There is good reason to think that, in every case of perceptual consciousness, there is something of which we are conscious; but there is also good reason to think that, in some cases of perceptual consciousness—for instance, hallucinations—there is nothing of which we are conscious. This paper resolves this inconsistency—which we call the presentation problem—by (a) arguing that ‘conscious of’ and related expressions function as intensional transitive verbs and (b) defending a particular semantic approach to such verbs, on which they (...) have readings that lack direct objects or themes. The paper further argues that this approach serves not only as a linguistic proposal about the semantics of ‘conscious of’, but also as a proposal about the metaphysics of conscious states. (shrink)

This paper examines the integration and unification of the philosophy and psychology of well-being. For the most part, these disciplines investigate well-being without reference to each other. In recent years, however, with the maturing of each discipline, there have been a growing number of calls to integrate the two. While such calls are welcome, what it means to integrate well-being philosophy and psychology can vary greatly depending on one’s theoretical and practical ends. The aim of this paper is to provide (...) a novel conceptual framework for thinking about integrating well-being philosophy and psychology that systematically categorizes different kinds of integration projects. We divide existing attempts in the literature into three broad categories according to the perspective from which the integration takes place: (1) top-down meta-theoretical unification; (2) psychological integration within philosophy; and (3) philosophical integration within psychology. These categories are then broken down into various further subcategories. Our aim in providing this framework is both to facilitate the assessment and comparison of existing integration attempts and to provide a roadmap for future integration attempts. For each category, we discuss one or two representative examples of the approaches. By doing so, we hope to generate interest in the wide variety of existing integration projects, as well as to generate discussion concerning the benefits and pitfalls of different approaches.

Psychopaths routinely disregard social norms by engaging in selfish, antisocial, often violent behavior. Commonly characterized as mentally disordered, recent evidence suggests that psychopaths are executing a well-functioning, if unscrupulous strategy that historically increased reproductive success at the expense of others. Natural selection ought to have favored strategies that spared close kin from harm, however, because actions affecting the fitness of genetic relatives contribute to an individual’s inclusive fitness. Conversely, there is evidence that mental disorders can disrupt psychological mechanisms designed to (...) protect relatives. Thus, mental disorder and adaptation accounts of psychopathy generate opposing hypotheses: psychopathy should be associated with an increase in the victimization of kin in the former account but not in the latter. Contrary to the mental disorder hypothesis, we show here in a sample of 289 violent offenders that variation in psychopathy predicts a decrease in the genetic relatedness of victims to offenders; that is, psychopathy predicts an increased likelihood of harming non-relatives. Because nepotistic inhibition in violence may be caused by dispersal or kin discrimination, we examined the effects of psychopathy on (1) the dispersal of offenders and their kin and (2) sexual assault frequency (as a window on kin discrimination). Although psychopathy was negatively associated with coresidence with kin and positively associated with the commission of sexual assault, it remained negatively associated with the genetic relatedness of victims to offenders after removing cases of offenders who had coresided with kin and cases of sexual assault from the analyses. These results stand in contrast to models positing psychopathy as a pathology, and provide support for the hypothesis that psychopathy reflects an evolutionary strategy largely favoring the exploitation of non-relatives.

Prior’s puzzle is standardly taken to be the puzzle of why, given the assumption that that-clauses denote propositions, substitution of “the proposition that P” for “that P” within the complements of many propositional attitude verbs is invalid. I show that Prior’s puzzle is much more general than is ordinarily supposed. There are two variants on the substitutional form of the puzzle—a quantificational variant and a pronominal variant—and all three forms of the puzzle arise in a wide range of grammatical positions, (...) rather than merely in the complements of propositional attitude verbs. The generalized puzzle shows that a range of proposed solutions to the original puzzle fail, or are radically incomplete, and also reveals the connections between Prior’s puzzle and debates over the nature of semantic types and higher-order quantification. I go on to develop a novel, higher-order solution to the generalized form of the puzzle, and I argue that this higher-approach is superior to its first-order alternatives. (shrink)

Ramsification is a well-known method of defining theoretical terms that figures centrally in a wide range of debates in metaphysics. Prior's puzzle is the puzzle of why, given the assumption that that-clauses denote propositions, substitution of "the proposition that P" for "that P" within the complements of many propositional attitude verbs sometimes fails to preserve truth, and other times fails to preserve grammaticality. On the surface, Ramsification and Prior's puzzle appear to have little to do with each other. But Prior's (...) puzzle is much more general than is ordinarily appreciated, and Ramsification requires a solution to the generalized form of Prior's puzzle. Without such a solution, a wide range of theories will either fail to imply their Ramsey sentences, or have Ramsey sentences that are ill-formed. As a consequence, definitions of theoretical terms given using the Ramsey sentence will be either incorrect or nonsensical. I present a partial solution to the puzzle that requires making use of a neo-Davidsonian language for scientific theorizing, but the would-be Ramsifier still faces serious challenges. (shrink)

The many-property problem has traditionally been taken to show that the adverbial theory of perception is untenable. This paper first shows that several widely accepted views concerning the nature of perception---including both representational and non-representational views---likewise face the many-property problem. It then presents a solution to the many-property problem for these views, but goes on to show how this solution can be adapted to provide a novel, fully compositional solution to the many-property problem for adverbialism. Thus, with respect to the (...) many-property problem, adverbialism and several widely accepted views in the philosophy of perception are on a par, and the problem is solved. (shrink)

Following neo-Aristotelians Alasdair MacIntyre and Martha Nussbaum, we claim that humans are story-telling animals who learn from the stories of diverse others. Moral agents use rational emotions, such as compassion which is our focus here, to imaginatively reconstruct others’ thoughts, feelings and goals. In turn, this imaginative reconstruction plays a crucial role in deliberating and discerning how to act. A body of literature has developed in support of the role narrative artworks (i.e. novels and films) can play in allowing us (...) the opportunity to engage imaginatively and sympathetically with diverse characters and scenarios in a safe protected space that is created by the fictional world. By practising what Nussbaum calls a ‘loving attitude’, her version of ethical attention, we can form virtuous habits that lead to phronesis (practical wisdom). In this paper, and taking compassion as an illustrative focus, we examine the ways that students’ moral education might usefully develop from engaging with narrative artworks through Philosophy for Children (P4C), where philosophy is a praxis, conducted in a classroom setting using a Community of Inquiry (CoI). We argue that narrative artworks provide useful stimulus material to engage students, generate student questions, and motivate philosophical dialogue and the formation of good habits which, in turn, supports the argument for philosophy to be taught in schools.

A study was carried out from October, 2020 to September, 2021to investigate the diversity of fishes and the conservation status of Chittaura Jheel (Bahraich), Uttar Pradesh. During the study period, 38 fish species belonging to 28 genera, 14 families and 7 orders have been identified. The order Cypriniformes was found the dominated order with 15 species(39.47%) followed by Siluriformes 10 species (26.31%), Perciformes 4 species (10.52%), Ophiocephaliformes 4 species (10.52%), Synbranchiformes2 species (5.26%), Osteoglossiformes 2 species (5.26%) and Clupiformes 1 species (...) (2.63 %), The present investigation showed that the wetland, Chittaura Jheel possesses rich fish biodiversity but proper conservation measures are required to maintain sustainability and richness of the fish species diversity of that wetland of U.P. According to IUCN, 30 were enlisted as Least Concern (LC), 2 species as near endangered (NE), 3 species as near threatened (NT), 2 listed as Endangered (EN) and 1 species was listed as Vulnerable (VU). There is a need of conservation of fish diversity of this natural wetland. The pressure is increasing day by day due to increasing population, leading to loss of fish diversity hence identifying the problem and making a better management plan is the way for conservation of the fish diversity of the Chittaura Jheel, a wetland of Bahraich district of Uttar Pradesh.

Trust is vital for individuals to flourish and have a sense of well-being in their community. A trusting society allows people to feel safe, communicate with each other and engage with those who are different to themselves without feeling fearful. In this paper I employ an Aristotelian framework in order to identify trust as a virtue and I defend the need to cultivate trust in children. I discuss the case study of Buranda State School in Queensland, Australia as an instance (...) of successful school reform that reinstates trust in an educational setting. Buranda makes use of the community of inquiry (CoI) pedagogy practiced by advocates of philosophy for children (P4C). Educators may create a safe space in the classroom by using the CoI and giving children the chance to voice their ideas and build upon, as well as question, those of others in a democratic and respectful manner.

The puzzle of Macbeth's dagger is the question of whether, in having his fatal vision of a dagger, Macbeth sees a dagger. I answer this question by addressing a more general one: the question of whether perceptual verbs are intensional transitive verbs (ITVs). I present seven experiments, each of which tests a collection of perceptual verbs for one of the three features characteristic of ITVs. One of (...) these features is Nonexistence: the failure of sentences involving transitive verbs to entail the existence of their direct objects. The experiments reveal that with respect to all three of these features, "see" behaves much more like a paradigmatically extensional verb than an intensional one. But surprisingly, unlike "see", "perceive" behaves much more like a paradigmatically intensional verb. This shows that the category of perceptual verbs is not uniform with respect to the features of intensionality; while Macbeth does not see a dagger, he may still perceive one. (shrink)

Gauss’s quadratic reciprocity theorem is among the most important results in the history of number theory. It’s also among the most mysterious: since its discovery in the late 18th century, mathematicians have regarded reciprocity as a deeply surprising fact in need of explanation. Intriguingly, though, there’s little agreement on how the theorem is best explained. Two quite different kinds of proof are most often praised as explanatory: an elementary argument that gives the theorem an intuitive geometric interpretation, due to Gauss (...) and Eisenstein, and a sophisticated proof using algebraic number theory, due to Hilbert. Philosophers have yet to look carefully at such explanatory disagreements in mathematics. I do so here. According to the view I defend, there are two important explanatory virtues—depth and transparency—which different proofs (and other potential explanations) possess to different degrees. Although not mutually exclusive in principle, the packages of features associated with the two stand in some tension with one another, so that very deep explanations are rarely transparent, and vice versa. After developing the theory of depth and transparency and applying it to the case of quadratic reciprocity, I draw some morals about the nature of mathematical explanation. (shrink)

A Study of Perennial Philosophy and Psychedelic Experience, with a Proposal to Revise W. T. Stace’s Core Characteristics of Mystical Experience ©Ed D’Angelo 2018 -/- Abstract -/- According to the prevailing paradigm in psychedelic research today, when used within an appropriate set and setting, psychedelics can reliably produce an authentic mystical experience. According to the prevailing paradigm, an authentic mystical experience is one that possesses the common or universal characteristics of mystical experience as identified by the philosopher W. T. Stace (...) in his 1960 work Mysticism and Philosophy. Stace’s common characteristics of mystical experience are the basis for the Hood Mysticism Questionnaire, which is the most widely used quantitative measure of mystical experience in experimental studies of psychedelic experience. In this paper, I trace the historical roots of Stace’s common characteristics of mystical experience back to Christian Neoplatonism and apophatic theology, and I trace those, in turn, back to Plato’s concept of the Good and to Aristotle’s concept of God as active intellect. I argue that Stace’s common characteristics of mystical experience are not universal or culturally invariant but are the product of a specifically Christian religious and moral tradition that has its roots in ancient Greek metaphysics. My paper concludes with a revised list of common characteristics of psychedelic experience that is a better candidate for a list of invariant structures of psychedelic experience than Stace’s common characteristics of Christian mystical experience.

This paper rigorously examines the primitive foundations of economic reasoning through an original framework based on symbolic logic. Extending previous work, it formalizes economic conceptions (\(\mathbb{C}\)), symbols (\(s_i\)), and introduces a structured language (\(\mathcal{L_{\mathbb{C}}}\)) to define their formation and interpretation. Organized as a continuous chain of declarations and illustrations, the paper offers a concise, systematic approach to understanding the philosophy of economic reasoning through formal representations.

This paper is an original attempt to understand the foundations of economic reasoning. It endeavors to rigorously define the relationship between subjective interpretations and objective valuations of such interpretations in the context of theoretical economics. This analysis is substantially expanded through a dynamic approach, where the truth of a valuation results in an updated interpretation or changes in the agent's subjective belief regarding the effectiveness of the selected action as well as the objective reality of the effectiveness of all other (...) possible actions (i.e. consequence realization). Complications arise when the economic agent is presented with a set of actions that render ambiguous preference, or when the effectiveness of an action cannot be perceived upon its selection, thereby necessitating a different theory of choice and consequence realization.
