This paper evaluates Howe and Leota/Turp's accounts of gamesmanship by examining case studies of gamesmanship from professional darts. While Leota and Turp make some substantial improvements on Howe in reconceptualizing the idea of sporting excellence, I claim that there are points of criticism that must be addressed, notably in their claims that sports do not prescribe necessary skills, and that it is impossible to distinguish between legitimate sporting strategy unaccounted for by the rules on the one hand, and (...) gamesmanship on the other. Leota and Turp criticise Howe’s account of rules for being misconceived: rather than rules prescribing necessary skills as Howe claims, rules actually proscribe skills and set limits on behaviour, rather than prescribing skills. I use darts and other sports to make the case that rules actually do both things. Elsewhere, in the phenomenon of ‘grouping’, I argue that we find a skill completely unaccounted for by the rules of darts and not a necessary skill for playing darts, which nonetheless counts as excellence for darts. This problematizes some claims from Leota and Turp on which their account of gamesmanship hinges. An aspect of Howe, Leota and Turp’s accounts on which they all agree is the importance of psychological resilience in sporting endeavours, which I discuss with reference to darts and rule changes in professional sport. The article ends with a discussion of an example from darts of a potential gamesmanship strategy, from a match between Michael van Gerwen and Darius Labanauskas, that unquestionably remains within the rules of the sport and which could not be eradicated through rule changes because it would violate the spirit of the sport. This is an interesting, controversial example for studies of the different forms of gamesmanship and their categorization, and indicates some limitations on what I say in my argument. (shrink)

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

This paper offers a new account of metaphysical explanation. The account is modelled on Kitcher’s unificationist approach to scientific explanation. We begin, in Sect. 2, by briefly introducing the notion of metaphysical explanation and outlining the target of analysis. After that, we introduce a unificationist account of metaphysical explanation before arguing that such an account is capable of capturing four core features of metaphysical explanations: irreflexivity, non-monotonicity, asymmetry and relevance. Since the unificationist theory of metaphysical explanation inherits irreflexivity and non-monotonicity (...) directly from the unificationist theory of scientific explanation that underwrites it, we focus on demonstrating how the account can secure asymmetry and relevance.

There is good reason to believe that scientific realism requires a commitment to the objective modal structure of the physical world. Causality, equilibrium, laws of nature, and probability all feature prominently in scientific theory and explanation, and each one is a modal notion. If we are committed to the content of our best scientific theories, we must accept the modal nature of the physical world. But what does the scientific realist’s commitment to physical modality require? We consider whether scientific realism (...) is compatible with Humeanism about the laws of nature, and we conclude that it is not. We specifically identify three major problems for the best-systems account of lawhood: its central concept of strength cannot be formulated non-circularly, it cannot offer a satisfactory account of the laws of the special sciences, and it can offer no explanation of the success of inductive inference. In addition, Humeanism fails to be naturalistically motivated. For these reasons, we conclude that the scientific realist must embrace natural necessity. (shrink)

In the past few years there has been a turn towards evaluating the empirical foundation of epistemic contextualism using formal (rather than armchair) experimental methods. By-and-large, the results of these experiments have not supported the original motivation for epistemic contextualism. That is partly because experiments have only uncovered effects of changing context on knowledge ascriptions in limited experimental circumstances (when contrast is present, for example), and partly because existing experiments have not been designed to distinguish between contextualism and one of (...) its main competing theories, subject-sensitive invariantism. In this paper, we discuss how a particular, "third-person", experimental design is needed to provide evidence that would support contextualism over subject-sensitive invariantism. In spite of the theoretical significance of third-person knowledge ascriptions for debates surrounding contextualism, no formal experiments evaluating such ascriptions that assess contextualist claims have previously been conducted. In this paper, we conduct an experiment specifically designed to examine that central gap in contextualism’s empirical foundation. The results of our experiment provide crucial support for epistemic contextualism over subject-sensitive invariantism. (shrink)

Many philosophers have assumed that our preferences regarding hedonic events exhibit a bias toward the future: we prefer positive experiences to be in our future and negative experiences to be in our past. Recent experimental work by Greene et al. (ms) confirmed this assumption. However, they noted a potential for some participants to respond in a deviant manner, and hence for their methodology to underestimate the percentage of people who are time neutral, and overestimate the percentage who are future biased. (...) We aimed to replicate their study using an alternative methodology that ensures there are no such deviant responses, and hence more accurately tracks future bias and time neutrality. Instead of finding more time neutrality than Greene et al., however, we found vastly more past bias. Our explanation for this surprising finding helps to reveal the rationale behind both future and past biased preferences, and undermines the generalisability of one of the most influential motivations for the rationality of hedonic future bias: Parfit’s My Past or Future Operations.

A standard line in the contemporary philosophical literature has it that physical theories are equivalent only when they agree on their empirical content, where this empirical content is often understood as being encoded in the equations of motion of those theories. In this article, we question whether it is indeed the case that the empirical content of a theory is exhausted by its equations of motion, showing that (for example) considerations of boundary conditions play a key role in the empirical (...) equivalence (or otherwise) of theories. Having argued for this, we show that philosophical claims made by Weatherall (2016) that electromagnetism in the Faraday tensor formalism is equivalent to electromagnetism in the vector potential formalism, and by Knox (2011) that general relativity is equivalent to teleparallel gravity, can both be called into question. We then show that properly considering the role of boundary conditions in theory structure can potentially restore these claims of equivalence and close with some remarks on the pragmatics of adjudications on theory identity.

Serious actualists take it that all properties are existence entailing. I present a simple puzzle about sentence tokens which seems to show that serious actualism is false. I then consider the most promising response to the puzzle. This is the idea that the serious actualist should take ordinary property-talk to contain an implicit existential presupposition. I argue that this approach does not work: it fails to generalise appropriately to all sentence types and tokens. In particular, it fails to capture the (...) right distinctions we ought to make between what I call _typographical sentence types_—an interesting and previously undiscussed class of fine-grained sentence types which are partially individuated by their typography, or how they look when written out.

This study analyzed the monitoring and evaluation of HIV/AIDS prevention programs in Southern Senatorial District of Cross River State, Nigeria. The study considered different levels of care/support and tested for locational variations in the monitoring/evaluation of HIV/AIDs prevention programs. A descriptive survey research design was utilized. This study covered 596 public health employees (doctors, nurses, pharmacists, and laboratory employees) in the study area. A sample of 239 respondents was chosen using the proportional stratified random sampling procedure. Data was collected using (...) a questionnaire constructed by the researchers and validated by specialists. Data gathered were analyzed using descriptive and inferential statistics. Results indicated that HIV/AIDs programs have been successfully monitored/evaluated to a high extent. High rates of success in the monitoring/evaluation of HIV/AIDs prevention programs are attributable to high rates of care/support provided to people living with HIV/AIDs. There was a significant variation in the monitoring/evaluation of HIV/AIDs prevention programs based on the location of health facilities, with higher rates recorded for urban areas. Based on the findings, it was concluded that the monitoring/evaluation of HIV/AIDs prevention programs in the Southern Senatorial District of Cross River State had recorded a significant level of success. The study recommended, among others, that there should be even distribution of medical facilities, resources and personnel to both urban and rural areas to promote equity and access to materials needed to contain or mitigate the spread of the pandemic across all locations.

In 1947 Donald Cary Williams claimed in The Ground of Induction to have solved the Humean problem of induction, by means of an adaptation of reasoning first advanced by Bernoulli in 1713. Later on David Stove defended and improved upon Williams’ argument in The Rational- ity of Induction (1986). We call this proposed solution of induction the ‘Williams-Stove sampling thesis’. There has been no lack of objections raised to the sampling thesis, and it has not been widely accepted. In our (...) opinion, though, none of these objections has the slightest force, and, moreover, the sampling thesis is undoubtedly true. What we will argue in this paper is that one particular objection that has been raised on numerous occasions is misguided. This concerns the randomness of the sample on which the inductive extrapolation is based. (shrink)

In this paper we propose that our understanding of pathocentric epistemic injustices can be enriched if they are theorised in terms of predicaments. These are the wider socially scaffolded structures of epistemic challenges, dangers, needs, and threats experienced by ill persons due to their particular emplacement within material, social, and epistemic structures. In previous work we have described certain aspects of these predicaments - pathocentric epistemic injustices, pathophobia, and so on. We argue that thinking predicamentally helps us integrate the various (...) social, epistemic, and practical obstacles experienced by ill persons and also unify the many concepts available for theorising them (microaggessions, epistemic injustices, and so on).

If a person requires an organ or tissue donation to survive, many philosophers argue that whatever moral responsibility a biological relative may have to donate to the person in need will be grounded at least partially, if not entirely, in biological relations the potential donor bears to the recipient. We contend that such views ignore the role that a potential donor's unique ability to help the person in need plays in underwriting such judgments. If, for example, a sperm donor is (...) judged to have a significant moral responsibility to donate tissue to a child conceived with his sperm, we think this will not be due to the fact that the donor stands in a close biological relationship to the recipient. Rather, we think such judgments will largely be grounded in the presumed unique ability of the sperm donor to help the child due to the compatibility of his tissues and organs with those of the recipient. In this paper, we report the results of two studies designed to investigate the comparative roles that biological relatedness and unique ability play in generating judgments of moral responsibility in tissue donation cases. We found that biologically related individuals are deemed to have a significant moral responsibility to donate tissue only when they are one of a small number of people who have the capacity to help.

In the field of machine consciousness, it has been argued that in order to build human-like conscious machines, we must first have a computational model of qualia. To this end, some have proposed a framework that supports qualia in machines by implementing a model with three computational areas (i.e., the subconceptual, conceptual, and linguistic areas). These abstract mechanisms purportedly enable the assessment of artificial qualia. However, several critics of the machine consciousness project dispute this possibility. For instance, Searle, in his (...) Chinese room objection, argues that however sophisticated a computational system is, it can never exhibit intentionality; thus, would also fail to exhibit consciousness or any of its varieties. This paper argues that the proposed architecture mentioned above answers the problem posed by Searle, at least in part. Specifically, it argues that we could reformulate Searle’s worries in the Chinese room in terms of the three-stage artificial qualia model. And by doing so, we could see that the person doing all the translations in the room could realize the three areas in the proposed framework. Consequently, this demonstrates the actualization of self-consciousness in machines. (shrink)

This paper focuses on the research field of machine ethics and how it relates to a technological singularity—a hypothesized, futuristic event where artificial machines will have greater-than-human-level intelligence. One problem related to the singularity centers on the issue of whether human values and norms would survive such an event. To somehow ensure this, a number of artificial intelligence researchers have opted to focus on the development of artificial moral agents, which refers to machines capable of moral reasoning, judgment, and decision-making. (...) To date, different frameworks on how to arrive at these agents have been put forward. However, there seems to be no hard consensus as to which framework would likely yield a positive result. With the body of work that they have contributed in the study of moral agency, philosophers may contribute to the growing literature on artificial moral agency. While doing so, they could also think about how the said concept could affect other important philosophical concepts. (shrink)

There has been a general failure among mental health theorists and social psychologists to understand the etiology of work-engendered depression. Yet the condition is increasingly prevalent in highly industrialized societies, where an exclusionary focus upon work, money, and the things that money can buy has displaced values that traditionally exerted a liberating and humanizing influence. Social critics have called the result an impoverishment of the spirit, a state of cultural bankruptcy, and an incapacity for genuine leisure. From a clinical perspective, (...) the condition has been diagnosed as widespread narcissism and obsessive work. -/- Acedia, a concept developed by the Scholastics, throws clarifying light on the origin of this form of depression.

In the past few decades, peer review has come to dominate virtually all professionally respectable academic and scientific publications. However, despite its near-universal acceptance, no code of conduct has been developed to which peer reviewers and their editors are encouraged to adhere. This paper proposes such a code of conduct.

It is available under its title through PhilPapers and other philosophy online archives. ●●●●● COMMENDATIONS OF THIS WORK, from the back cover of the published edition: ●●●●● “I admire its range of philosophical vision.” – Nicholas Rescher, Distinguished University Professor of Philosophy, University of Pittsburgh, author of more than 100 books. ●●●●● “Bartlett’s _Critique of Impure Reason_ is an impressive, bold, and ambitious work. Careful scholarship is balanced by original analyses that lead the reader to recognize the limits of meaning, knowledge, and conceptual possibility. The work addresses a host of traditional philosophical problems, among them the nature of space, time, causality, consciousness, the self, other minds, ontology, free will and determinism, and others. The book culminates in a fascinating and profound new understanding of relativity physics and quantum theory.” – Gerhard Preyer, Professor of Philosophy, Goethe-University, Frankfurt am Main, Germany, author of many books including _Concepts of Meaning_, _Beyond Semantics and Pragmatics_, _Intention and Practical Thought_, and _Contextualism in Philosophy_. ●●●●● “[This work’s] goal is of a unique and difficult species: Dr. Bartlett seeks to develop a formal logical calculus on the basis of transcendental philosophical arguments; in fact, he hopes that this calculus will be the formal expression of the transcendental foundation of knowledge.... I consider Dr. Bartlett’s work soundly conceived and executed with great skill.” – C. F. von Weizsäcker, philosopher and physicist, former Director, Max-Planck-Institute, Starnberg, Germany. ●●●●● “Bartlett has written an American “Prolegomena to All Future Metaphysics.” He aims rigorously to eliminate meaningless assertions, reach bedrock, and place philosophy on a firm foundation that will enable it, like science and mathematics, to produce lasting results that generations to come can build on. This is a great book, the fruit of a lifetime of research and reflection, and it deserves serious attention.” — Martin X. Moleski, former Professor, Canisius College, Buffalo, NY, studies of scientific method, the presuppositions of thought, and the self-referential nature of epistemology. ●●●●● “Bartlett has written a book on what might be called the underpinnings of philosophy. It has fascinating depth and breadth, and is all the more striking due to its unifying perspective based on the concepts of reference and self-reference.” – Don Perlis, Professor of Computer Science, University of Maryland, author of numerous publications on self-adjusting autonomous systems and philosophical issues concerning self-reference, mind, and consciousness. ●●●●● ●●●●● The _Critique of Impure Reason: Horizons of Possibility and Meaning_ comprises a major and important contribution to philosophy. Thanks to the generosity of its publisher, this massive 885-page volume has been published as a free open access eBook (3.75MB) as well as an open access printed edition. It inaugurates a revolutionary paradigm shift in philosophical thought by providing compelling and long-sought-for solutions to a wide range of philosophical problems. In the process, the work fundamentally transforms the way in which the concepts of reference, meaning, and possibility are understood. The book includes a Foreword by the celebrated German philosopher and physicist Carl Friedrich von Weizsäcker. ●●●●● In Kant’s _Critique of Pure Reason_ we find an analysis of the preconditions of experience and of knowledge. In contrast, but yet in parallel, the new _Critique_ focuses upon the ways—unfortunately very widespread and often unselfconsciously habitual—in which many of the concepts that we employ _conflict_ with the very preconditions of meaning and of knowledge. ●●●●● This is a book about the boundaries of frameworks and about the unrecognized conceptual confusions in which we become entangled when we attempt to transgress beyond the limits of the possible and meaningful. We tend either not to recognize or not to accept that we all-too-often attempt to trespass beyond the boundaries of the frameworks that make knowledge possible and the world meaningful. ●●●●● The _Critique of Impure Reason_ proposes a bold, ground-breaking, and startling thesis: that a great many of the major philosophical problems of the past can be solved through the recognition of a viciously deceptive form of thinking to which philosophers as well as non-philosophers commonly fall victim. For the first time, the book advances and justifies the criticism that a substantial number of the questions that have occupied philosophers fall into the category of “impure reason,” violating the very conditions of their possible meaningfulness. ●●●●● The purpose of the study is twofold: first, to enable us to recognize the boundaries of what is referentially forbidden—the limits beyond which reference becomes meaningless—and second, to avoid falling victims to a certain broad class of conceptual confusions that lie at the heart of many major philosophical problems. As a consequence, the boundaries of _possible meaning_ are determined. ●●●●● Bartlett, the author or editor of more than 20 books, is responsible for identifying this widespread and delusion-inducing variety of error, _metalogical projection_. It is a previously unrecognized and insidious form of erroneous thinking that undermines its own possibility of meaning. It comes about as a result of the pervasive human compulsion to seek to transcend the limits of possible reference and meaning. ●●●●● Based on original research and rigorous analysis combined with extensive scholarship, the _Critique of Impure Reason_ develops a self-validating method that makes it possible to recognize, correct, and eliminate this major and pervasive form of fallacious thinking. In so doing, the book provides at last provable and constructive solutions to a wide range of major philosophical problems. ●●●●● CONTENTS AT A GLANCE ▪▪▪▪▪ Preface ▪▪▪▪▪ Foreword by Carl Friedrich von Weizsäcker ▪▪▪▪▪ Acknowledgments ▪▪▪▪▪ Avant-propos: A philosopher’s rallying call ▪▪▪▪▪ Introduction ▪▪▪▪▪ A note to the reader ▪▪▪▪▪ A note on conventions ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART I ▪▪▪▪▪ ▪▪▪▪▪ WHY PHILOSOPHY HAS MADE NO PROGRESS AND HOW IT CAN ▪▪▪▪▪ 1 Philosophical-psychological prelude ▪▪▪▪▪ 2 Putting belief in its place: Its psychology and a needed polemic ▪▪▪▪▪ 3 Turning away from the linguistic turn: From theory of reference to metalogic of reference ▪▪▪▪▪ 4 The stepladder to maximum theoretical generality ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART II ▪▪▪▪▪ THE METALOGIC OF REFERENCE ▪▪▪▪▪ A New Approach to Deductive, Transcendental Philosophy ▪▪▪▪▪ 5 Reference, identity, and identification ▪▪▪▪▪ 6 Self-referential argument and the metalogic of reference ▪▪▪▪▪ 7 Possibility theory ▪▪▪▪▪ 8 Presupposition logic, reference, and identification ▪▪▪▪▪ 9 Transcendental argumentation and the metalogic of reference ▪▪▪▪▪ 10 Framework relativity ▪▪▪▪▪ 11 The metalogic of meaning ▪▪▪▪▪ 12 The problem of putative meaning and the logic of meaninglessness ▪▪▪▪▪ 13 Projection ▪▪▪▪▪ 14 Horizons ▪▪▪▪▪ 15 De-projection ▪▪▪▪▪ 16 Self-validation ▪▪▪▪▪ 17 Rationality: Rules of admissibility ▪▪▪▪▪ ▪▪▪▪▪ ▪▪▪▪▪ PART III ▪▪▪▪▪ PHILOSOPHICAL APPLICATIONS OF THE METALOGIC OF REFERENCE ▪▪▪▪▪ Major Problems and Questions of Philosophy and the Philosophy of Science ▪▪▪▪▪ 18 Ontology and the metalogic of reference ▪▪▪▪▪ 19 Discovery or invention in general problem-solving, mathematics, and physics ▪▪▪▪▪ 20 The conceptually unreachable: “The far side” ▪▪▪▪▪ 21 The projections of the external world, things-in-themselves, other minds, realism, and idealism ▪▪▪▪▪ 22 The projections of time, space, and space-time ▪▪▪▪▪ 23 The projections of causality, determinism, and free will ▪▪▪▪▪ 24 Projections of the self and of solipsism ▪▪▪▪▪ 25 Non-relational, agentless reference and referential fields ▪▪▪▪▪ 26 Relativity physics as seen through the lens of the metalogic of reference ▪▪▪▪▪ 27 Quantum theory as seen through the lens of the metalogic of reference ▪▪▪▪▪ 28 Epistemological lessons learned from and applicable to relativity physics and quantum theory ▪▪▪▪▪ ▪▪▪▪▪ PART IV ▪▪▪▪▪ HORIZONS ▪▪▪▪▪ 29 Beyond belief ▪▪▪▪▪ 30 _Critique of Impure Reason_: Its results in retrospect ▪▪▪▪▪ ▪▪▪▪▪ SUPPLEMENT ▪▪▪▪▪ The Formal Structure of the Metalogic of Reference ▪▪▪▪▪ APPENDIX I ▪▪▪▪▪ The Concept of Horizon in the Work of Other Philosophers ▪▪▪▪▪ APPENDIX II ▪▪▪▪▪ Epistemological Intelligence ▪▪▪▪▪ References ▪▪▪▪▪ Index ▪▪▪▪▪ About the author.

Quantum Counterfactual Communication is the recently-proposed idea of using quantum physics to send messages between two parties, without any matter/energy transfer associated with the bits sent. While this has excited massive interest, both for potential ‘unhackable’ communication, and insight into the foundations of quantum mechanics, it has been asked whether this process is essentially quantum, or could be performed classically. We examine counterfactual communication, both classical and quantum, and show that the protocols proposed so far for sending signals that don’t (...) involve matter/energy transfer associated with the bits sent must be quantum, insofar as they require wave-particle duality.

Biological order provided by α-helical secondary protein structures is an important resource exploitable by living organisms for increasing the efficiency of energy transport. In particular, self-trapping of amide I energy quanta by the induced phonon deformation of the hydrogen-bonded lattice of peptide groups is capable of generating either pinned or moving solitary waves following the Davydov quasiparticle/soliton model. The effect of applied in-phase Gaussian pulses of amide I energy, however, was found to be strongly dependent on the site of application. (...) Moving solitons were only launched when the amide I energy was applied at one of the α-helix ends, whereas pinned solitons were produced in the α-helix interior. In this paper, we describe a general mechanism that launches moving solitons in the interior of the α-helix through phase-modulated Gaussian pulses of amide I energy. We also compare the predicted soliton velocity based on effective soliton mass and the observed soliton velocity in computer simulations for different parameter values of the isotropy of the exciton-phonon interaction. The presented results demonstrate the capacity for explicit control of soliton velocity in protein α-helices, and further support the plausibility of gradual optimization of quantum dynamics for achieving specialized protein functions through natural selection.

The essential biological processes that sustain life are catalyzed by protein nano-engines, which maintain living systems in far-from-equilibrium ordered states. To investigate energetic processes in proteins, we have analyzed the system of generalized Davydov equations that govern the quantum dynamics of multiple amide I exciton quanta propagating along the hydrogen-bonded peptide groups in α-helices. Computational simulations have confirmed the generation of moving Davydov solitons by applied pulses of amide I energy for protein α-helices of varying length. The stability and mobility (...) of these solitons depended on the uniformity of dipole-dipole coupling between amide I oscillators, and the isotropy of the exciton-phonon interaction. Davydov solitons were also able to quantum tunnel through massive barriers, or to quantum interfere at collision sites. The results presented here support a nontrivial role of quantum effects in biological systems that lies beyond the mechanistic support of covalent bonds as binding agents of macromolecular structures. Quantum tunneling and interference of Davydov solitons provide catalytically active macromolecular protein complexes with a physical mechanism allowing highly efficient transport, delivery, and utilization of free energy, besides the evolutionary mandate of biological order that supports the existence of such genuine quantum phenomena, and may indeed demarcate the quantum boundaries of life.

This article focuses on a particular issue under machine ethics—that is, the nature of Artificial Moral Agents. Machine ethics is a branch of artificial intelligence that looks into the moral status of artificial agents. Artificial moral agents, on the other hand, are artificial autonomous agents that possess moral value, as well as certain rights and responsibilities. This paper demonstrates that attempts to fully develop a theory that could possibly account for the nature of Artificial Moral Agents may consider certain philosophical (...) ideas, like the standard characterizations of agency, rational agency, moral agency, and artificial agency. At the very least, the said philosophical concepts may be treated as signposts for further research on how to truly account for the nature of Artificial Moral Agents. (shrink)

The paper identifies defining characteristics of the principal models of problem-solving behavior which are useful in developing a general theory of problem-solving. An attempt is made both to make explicit those disagreements between theorists of different persuasions which have served as obstacles to an integrated approach, and to show that these disagreements have arisen from a number of conceptual confusions: The conflict between information processors and behavioral analysts has resulted from a common failure to understand theoretical sufficiency, and hence these (...) theorists have been at a loss to understand one another. Two directions of research in problem-solving, mechanical algorithmic problem-solving and the psychology of invention, have been thought to be divergent, but in fact complement one another once it is clear that problem-solving involves neither discovery nor invention, but rather is a matter of perceptual encoding and processing. Successful problem-solving behavior can be described as adaptive, learning behavior in which organization skills are effectively associated with situationally determined perceptual encoding processes of the individual mechanical or biological problem-solver.

The present study aimed to understand how status-oriented individual differences such as narcissistic antagonism, narcissistic extraversion, and moral grandstanding motivations may have longitudinally predicted both behavioral and social media responses during the early stages of the COVID-19 pandemic. Via YouGov, a nationally representative sample of U.S. adults was recruited in August of 2019 (N = 2,519; Mage = 47.5, SD = 17.8; 51.4% women) and resampled in May of 2020, (N = 1,533). Results indicated that baseline levels of narcissistic antagonism (...) were associated with lower levels of social distancing and lower compliance with public health recommended behaviors. Similarly, dominance oriented moral grandstanding motivations predicted greater conflict with others over COVID-19, greater engagement in status-oriented social media behaviors about COVID-19, and lower levels of social distancing.

Protein α-helices provide an ordered biological environment that is conducive to soliton-assisted energy transport. The nonlinear interaction between amide I excitons and phonon deformations induced in the hydrogen-bonded lattice of peptide groups leads to self-trapping of the amide I energy, thereby creating a localized quasiparticle (soliton) that persists at zero temperature. The presence of thermal noise, however, could destabilize the protein soliton and dissipate its energy within a finite lifetime. In this work, we have computationally solved the system of stochastic (...) differential equations that govern the quantum dynamics of protein solitons at physiological temperature, T=310 K, for either a single isolated α-helix spine of hydrogen bonded peptide groups or the full protein α-helix comprised of three parallel α-helix spines. The simulated stochastic dynamics revealed that although the thermal noise is detrimental for the single isolated α-helix spine, the cooperative action of three amide I exciton quanta in the full protein α-helix ensures soliton lifetime of over 30 ps, during which the amide I energy could be transported along the entire extent of an 18-nm-long α-helix. Thus, macromolecular protein complexes, which are built up of protein α-helices could harness soliton-assisted energy transport at physiological temperature. Because the hydrolysis of a single adenosine triphosphate molecule is able to initiate three amide I exciton quanta, it is feasible that multiquantal protein solitons subserve a variety of specialized physiological functions in living systems.

This article examines who or what should be the target of feminist criticism. Throughout the discussion, the concept of memes is applied in analyzing systems such as patriarchy and feminism itself. Adapting Dawkins' theory on genes, this research puts forward the possibility that patriarchies and feminisms are memeplexes competing for the limited energy and memory space of humanity.

Macromolecular protein complexes catalyze essential physiological processes that sustain life. Various interactions between protein subunits could increase the effective mass of certain peptide groups, thereby compartmentalizing protein α-helices. Here, we study the differential effects of applied massive barriers upon the soliton-assisted energy transport within proteins. We demonstrate that excentric barriers, localized onto a single spine in the protein α-helix, reflect or trap three-spine solitons as effectively as concentric barriers with comparable total mass. Furthermore, wider protein solitons, whose energy is lower, (...) require heavier massive barriers for soliton reflection or trapping. Regulation of energy transport, delivery and utilization at protein active sites could thus be achieved through control of the soliton width, or of the effective mass of the protein subunits.

In a recent Response published in the Journal of Medical Ethics,1 Buturovic provides two criticisms of my argument in ‘Is the exclusion of psychiatric patients from access to physician-assisted suicide discriminatory?’2 First, Buturovic argues that my argument effectively ‘erases the distinction between healthy adults and patients (whether somatic or psychiatric) essentially implying that PAS [physician-assisted suicide] should be available to all, for all reasons or, ultimately no reason’ (Buturovic,1 pg. 1). Second, Buturovic argues that opening the doors to medical assistance (...) in dying (MAID) for psychiatric patients could have a number of undesirable implications. In particular, Buturovic highlights the potential negative implications for relations of trust in medicine—psychiatry in particular—along with potential effects on the rate of organ donation. I would here like to respond to these two criticisms. In short, my response to Buturovic’s first argument is that the slope is not nearly as slippery as Buturovic suggests. The reason for this is that the plausibility of Buturovic’s argument rests on a significant misinterpretation of my argument, along with an important equivocation in her own. Buturovic argues that, under the three criteria that I propose for the provision of MAID—sufficient decision-making capacity, demonstrated treatment resistance, and a lack of substantially negative implications for existing standards of psychiatric treatment and research—the provision of MAID for trivial reasons, even no reason at all, is justifiable. The main problem with this argument is that I propose no such positive criteria. My argument is that none of the three arguments addressed in my previous paper are sufficient to justify the exclusion of any and all psychiatric patients from access to MAID. I do not claim, in other words, that any individual …. (shrink)

This essay revisits the topic of how we should measure the things that matter, at a time when we continue to mismeasure our lives, as we hold fast to outworn myths of usefulness, popularity, and the desire to influence others. /// Three central, unquestioned presumptions have come to govern much of contemporary society, education, and the professions. They are: the high value placed on usefulness, on the passion to achieve popularity, and on the desire to influence others. In this essay, (...) the psychologist-philosopher author makes the case against these presumptions, presumptions which lead to exclusionary commitments that stand in the way of human cultural development.

The author shares philosophical and biographical reflections, accompanied by photographs, on the lives of his well-known literary parents, poet Elizabeth Bartlett and writer/artist Paul Alexander Bartlett.

The American system of education makes important and sometimes unjustified assumptions that were questioned and criticized nearly a hundred years ago by author and educational theorist Albert Jay Nock. This essay discusses Nock’s theory of American education and finds that certain of these assumptions stand greatly in need of the support of evidence.

A psychological and historical study of college students from the standpoint of the psychology and history of American higher education and of liberal arts values.

The author considers the model-theoretic character of proofs and disproofs by means of attempted counterexample constructions, distinguishes this proof format from formal derivations, then contrasts two approaches to semantic tableaux proposed by Beth and Lambert-van Fraassen. It is noted that Beth's original approach has not as yet been provided with a precisely formulated rule of closure for detecting tableau sequences terminating in contradiction. To remedy this deficiency, a technique is proposed to clarify tableau operations.

Most explanations are either about events (why things happen), or about properties (why objects have the enduring characteristics that they do). Explanations of events have been studied extensively in philosophy and psychology, whereas the explanations of properties have received little or no attention in the literature. The present study is an exploration of the ways in which we explain various types of properties. Ten participants provided explanations of 45 properties by completing sentences of the form: “Xs have p because…” where (...) p is a property of the concept X. When coded into three traditional kinds of explanation (i.e. causal, purposive, categorical), nearly half of the explanations did not fit into any of these categories and were classified as “other”. Different patterns of preference for explanations emerged across the various property types for each domain. A qualitative analysis of the other kind revealed that the most frequent form of explanation involved another property of the object, as in ‘Xs have property p because they have property q”. Explanations of properties showed a homeostatic character. Simply relating two properties of a concept seems sufficient as an explanation of a property. (shrink)

Two prevalent assumptions in the philosophy of sport literature are that all sports are games and that all games are contests, meant to determine who is the better at the skills definitive of the sport. If these are correct, it would follow that all sports are contests and that a range of sporting activities, including nature sports, are not in fact sports at all. This paper first confronts the notion that sport and games must seek to resolve skill superiority through (...) consideration of sport activities that have no such aim. The reduction of sport to game is also shown to be untenable and due to misunderstanding the point of sport activities, specifically, why people engage in them. This leads to reconsideration of the dominance of an instrumental conception of sport and the pursuit of excellence as anthropomaximising efficiency. The Norwegian tradition of frilutsliv is explored as a counterpoint to both conventional and nature sport. (shrink)

Excellence in sport performance is normally taken to be a matter of superior performance of physical movements or quantitative outcomes of movements. This paper considers whether a wider conception can be afforded by certain kinds of nature based sport. The interplay between technical skill and aesthetic experience in nature based sports is explored, and the extent to which it contributes to a distinction between different sport-based approaches to natural environments. The potential for aesthetic appreciation of environmental engagement is found to (...) be strongly dependent on whether or not environmental engagement is exploited for the end of producing a quantifiable result or enhancing technical skill. It is also argued that an existential rather than spectatorial attitude to aesthetic experience is offered by specifically nature oriented sport. Aesthetic experience achieved in this way is therefore neither passive nor detached, but extends Berleant's concept of participatory environmental aesthetics and underpins both an alternate (wide) conception of excellence in sport activity and a richer experience of aesthetic engagement than more objectivised standpoints.

This paper responds to Kevin Krein’s claim in that the particular value of nature sports over traditional ones is that they offer intensity of sport experience in dynamic interaction between an athlete and natural features. He denies that this intensity is derived from competitive conflict of individuals and denies that nature sport derives its value from internal conflict within the athlete who carries out the activity. This paper responds directly to Krein by analysing ‘intensity’ in sport in terms of the (...) relationship between attention and reflection and the interaction between self and environment. I reply directly to Krein’s rejection of self-competition as based on a mischaracterisation of internal struggle and argue that the weighing of incompatible desires does not involve a fragmented self. I argue that the unique intensity to which Krein refers is strongly comparable to the Kantian conception of the sublime and explore how sublime experience fits Krein’s account and outline some serious problems that such an ideal of experience poses for nature sport.

This paper is an examination of the concept of recognition and its connection with identity and respect. This is related to the question of how women are or are not adequately recognised or respected for their achievements in sport and whether eliminating sex segregation in sport is a solution. This will require an analysis of the concept of excellence in sport, as well as the relationship between fairness and inclusion in an activity that is fundamentally about bodily movement. I argue (...) that attempts to address the problem of women’s recognition in sport need to do so in ways that neither eliminate sport as a fairness regulated system for developing individual excellence in bodily movement nor that prevent women’s achievement of sporting excellence, with the regard that belongs to them. Doing this requires us to decide whether sport is about champions or about individual excellence. (shrink)

This paper explores ludonarrative dissonance as it occurs in sport, primarily as the conflict experienced by participants between dominant narratives and self-generated interpretations of embodied experience. Taking self-narrative as a social rather than isolated production, the interaction with three basic categories of dominant narrative is explored: transformative, representing a spectrum from revelatory to distorting, bullying and colonising. These forms of dominant narrative prescribe interpretations of the player’s experience of play and of self that displace their own, with the end result (...) of dissonance and self-alienation.

In a recent paper, Kevin Krein argues that the notion of self-competition is misplaced in adventure sports and of only limited application altogether, for two main reasons: (i) the need for a consistent and repeatable measure of performance; and (ii) the requirement of multiple competitors. Moreover, where an individual is engaged in a sport in which the primary feature with which they are engaged is a natural one, Krein argues that the more accurate description of their activity is not 'competition', (...) but an attempt at harmonious interaction. I raise a number of problems against both criteria and argue that traditional and adventure sports do both involve self-competition on at least two levels: bettering one's previous performance and resisting the desire to quit. I argue that self-reflexive competition is not so much with one's self (which is philosophically absurd), but within one's self, between conflicting motivations and desires. I explore what is involved in self-reflexive competition, particularly at a phenomenological, self-constituting level, and raise the question of whether it is appropriate for activity in wilder natural environments.

Kierkegaard shows two contrary attitudes to woman and the feminine: misogyny and celebration. The Kierkegaardian structure of selfhood, because combined with a hierarchical assumption about the relative value of certain human characteristics, and their identification as male or female, argues that woman is a lesser self. Consequently, the claim that the Kierkegaardian ideal of selfhood is androgynist is rejected, though it is the latter assumptions alone that force this conclusion.

Previous discussions on the value of sport in remote locations have concentrated on 1) environmental and process concerns, with the rejection of competition and goal-directed or use oriented activity, or 2) the value of risk and dangerous sport for self-affirmation. It is argued that the value of risk in remote sport is in self-knowledge rather than self-affirmation and that risk in remote sport, while enhancing certain kinds of experience, is not necessary. The value of remote sport is in offering the (...) opportunity for experience that enhances the participants’ knowledge both of self and of the environment with which they interact. (shrink)

Deafferented subjects, while lacking proprioceptive awareness of much of their bodies, are nevertheless able to use their bodies in basic action. Sustained visual contact with the body parts of which they are no longer proprioceptively aware enables them to move these parts in a controlled way. This might be taken to straightforwardly show that proprioceptive awareness is inessential to bodily action. I, however, argue that this is not the case. Proprioceptive awareness figures essentially in our self-conscious unity as practical subjects. (...) Recognizing this allows us to better understand the nature of the impairment with which deafferented subjects live. (shrink)

This paper refines a number of theoretical distinctions relevant to deceptive play, in particular the difference between merely misleading actions and types of simulation commonly considered beyond the pale, such as diving. To do so, I rely on work in the philosophy of language about conversational convention and implicature, the distinction between lying and misleading, and their relation to concepts of seduction and bullshit. The paper works through a number of possible solutions to the question of what is wrong with (...) simulation and its difference from strategic fouling, including the argument that games and their rules operate like contracts. I conclude that the wrongness lies in the injustice of unfair advantage gained through actions that silence opposition by resort to unanswerable play. (shrink)
