First-year university students have multiple motives for studying and these motives may interact. Yet, past research has primarily focused on a variable-centered, dimensional approach missing out on the possibility to study the joint effect of multiple motives that students may have. Examining the interplay between motives is key to better explain student differences in study success and wellbeing, and to understand different effects that interventions can have in terms of wellbeing and study success. We therefore applied a student-centered, multidimensional (...) approach in which we explored motivational profiles of first-year university students by combining three dimensions of motives for studying which have been shown to be differently related to academic functioning. Using cluster analysis in two independent, consecutive university student cohorts, we identified four meaningful profiles and coined them motivational mindsets. We validated the four mindset profiles not only within each student sample but also found almost identical profiles between the student samples. The motivational mindset profiles were labeled: high-impact mindset, low-impact mindset, social-impact mindset, and self-impact mindset. In addition to validating the paradigm, we developed a mindset classification tool to further use these mindsets in practice and in future research. (shrink)

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are (...) proposed for finding missing reasons, for deductive arguments, e.g., semantic tableaux are suggested.

This article features long-sought proofs with intriguing properties (such as the absence of double negation and the avoidance of lemmas that appeared to be indispensable), and it features the automated methods for finding them. The theorems of concern are taken from various areas of logic that include two-valued sentential (or propositional) calculus and infinite-valued sentential calculus. Many of the proofs (in effect) answer questions that had remained open for decades, questions focusing on axiomatic proofs. The approaches we take are of (...) added interest in that all rely heavily on the use of a single program that offers logical reasoning, William McCune's automated reasoning program OTTER. The nature of the successes and approaches suggests that this program offers researchers a valuable automated assistant. This article has three main components. First, in view of the interdisciplinary nature of the audience, we discuss the means for using the program in question (OTTER), which flags, parameters, and lists have which effects, and how the proofs it finds are easily read. Second, because of the variety of proofs that we have found and their significance, we discuss them in a manner that permits comparison with the literature. Among those proofs, we offer a proof shorter than that given by Meredith and Prior in their treatment of ukasiewicz's shortest single axiom for the implicational fragment of two-valued sentential calculus, and we offer a proof for the ukasiewicz 23-letter single axiom for the full calculus. Third, with the intent of producing a fruitful dialogue, we pose questions concerning the properties of proofs and, even more pressing, invite questions similar to those this article answers.

In the last section of his Introduction to the Human Sciences Dilthey claims that from its very beginnings western metaphysics has been oriented towards a panlogistic goal that received its most adequate formulation in Leibniz’s principle of sufficient reason. According to Dilthey, this principle leaves little or no room for the sovereignity of the will and the personal freedom that man finds within his self-consciousness and lived experiences. In this paper we argue that Dilthey gives a rather one-sided and somewhat (...) distorted view not only of the goal of modern metaphysics, but also of the essence of human freedom. As a matter of fact the great metaphysicians of the 17th and 18th centuries considered the solution of the problem of human freedom the cornerstone of all metaphysics. However, unlike Dilthey, they sought to understand human freedom within the conceptual framework of grounds and reasons, thereby giving these notions a depth and a differentiation that are completely overlooked by Dilthey.

Language is a cognitively demanding human trait, but it is also a fundamentally cooperative enterprise that rests on the motivation to share information. Great apes possess many of the cognitive prerequisites for language, but largely lack the motivation to share information. Callitrichids (including marmosets and tamarins) are highly vocal monkeys that are more distantly related to humans than great apes are, but like humans, they are cooperative breeders and all group members help raising offspring. Among primates, this rearing system is (...) correlated with proactive prosociality, which can be expressed as motivation to share information. We therefore propose that the unique coincidence of these two components in humans set the stage for language evolution: The cognitive component inherited from our great ape-like ancestors, and the motivational one added convergently as a result of cooperative breeding. We evaluate this scenario based on a review of callitrichd vocal communication and show that furthermore, they possess many of the mechanistic elements emphasized by the mirror system hypothesis of language evolution. We end by highlighting how more systematic phylogenetic comparisons will enable us to further promote our understanding of the role of cooperative breeding during language evolution. (shrink)

A: Things that are equal to the same are equal to each other. B: The two sides of this triangle are things that are equal to the same. Z: So, the two sides of this triangle are equal to each other. Achilles fails because he encounters an infinite progression of hidden premises of the form “If all the premises of the argument are true, the conclusion is true”. In [a1], the hidden premise is H1 “If A and B then Z” (...) – surely, if one did not believe that H1 is true, one would have a reason not to accept the conclusion Z. So, the argument [a2] must lead to conclusion Z from A, B and H1. But, one will have to supplement [a2] with H2: “If A and B and H1 then Z” since if one did not believe H2 one would have a reason not to draw conclusion Z. And so on ad infinitum. The puzzle can be seen as arising through the application of an apparently innocent principle of discerning missing premises (§2). If looked at in this light, the standard response given to the paradox does not so much resolve the puzzle as legislates against it being raised with respect to principles of inference (§3). I argue that a fundamental ambiguity infests the test for what is a missing premise (§4). Moreover, it explains why the puzzle appears to, though it does not (§5), arise. I end with some comments on the usefulness of the test (§6). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dogma and Ecumenism: Vatican II and Karl Barth's Ad Limina Apostolorum ed. by Matthew Levering, Bruce L. McCormack, and Thomas Joseph White, O.P.Gavin D'CostaDogma and Ecumenism: Vatican II and Karl Barth's Ad Limina Apostolorum edited by Matthew Levering, Bruce L. McCormack, and Thomas Joseph White, O.P. (Washington, DC: Catholic University Press of America Press, 2020), ix + 369 pp.In May 1966 Karl Barth visited Rome. He was invited (...) to reflect on the Second Vatican Council, to ask questions to leading curial figures, and peritus theologians, as well as Pope Paul VI. Barth's book Ad Limina Apostolorum: An Appraisal of Vatican II contains his questions and an account from Barth of his visit, along with some other important essays. It is still deeply challenging in its incisiveness, despite its brevity. I have always been struck by Barth's Marian criticisms that are so central to his viewpoint about divine agency and human cooperation. These give us an excellent insight into his ecclesiology. They represent the reasons for much of his questioning of various Roman Catholic positions on all sorts of matters. Eberhard Busch's diaries, while Barth's assistant during this period, form a fascinating complimentary account of the visit. These tell of the not-so-fruitful visit to Augustin Cardinal Bea and the great highpoint (for Barth) of his one-hour audience with Pope Paul VI. Barth was impressed by the Jesuits during his visit, but not so much by the Dominicans. He thought the latter had absorbed too many streams of liberal modernity. The two Dominicans participating in this book turn those tides. Indeed, all the authors could be located within the conserving wings of their ecclesial membership, which makes the volume all the stronger in raising serious unresolved disagreements and noting important common ground. It is testimony to Barth's enduring value that this volume seems so timely. The Barth Centre at Princeton and the Pontifical Faculty of the Dominican House in Washington were the sponsors of this collection.The volume is structured around five of the key documents commented on by Barth, with a Catholic and Reformed voice reflecting on both the particular document and Barth's input (with the exception of Francesca Aran Murphy, who deals with George Lindbeck rather than Barth), thereby simultaneously pushing forward the Catholic–Reformed engagement with the Council and with Barth. There is a preface with a penetrating introduction by Thomas Joseph White, O.P., and an irenic opening chapter by Matthew Levering on biblical renewal at Vatican II. Then follow the twin reflections on the five documents.First (and rightly so) comes the Dogmatic Constitution on Revelation, Dei Verbum. Katherine Sonderegger develops a nuanced reflection on the metaphor of Scripture as mirror of God (found in Dei Verbum), showing [End Page 971] a deep appreciation of currents within Dei Verbum that Barth had not detected, but which are more connective with his concerns and preoccupations. Lewis Ayres rather impishly takes what Barth saw as the main weakness of the text (its chapter 2: "Handing on Divine Revelation") and makes it the greatest strength. Ayers provides a deeply learned and original exploration of the concept of "tradition" as sacramental. In this duet, Barth comes out looking like he may have missed hearing the melodies while too closely studying the score.Then follow two profound essays on Lumen Gentium, the Dogmatic Constitution on the Church. Christoph Schwöbel builds up a strong Protestant case for the necessary visible ecclesial identity of the Church, thus showing a deep convergence without denying differences that remain. White, in a deeply insightful and probing essay, goes to the heart of the ecclesiological difference between Barth and Yves Congar (and some other key Catholics at the time): the relationship between uncreated divine agency and created human agency, especially within the context of the post-apostolic Church. White suggests that, without some stable ecclesial mediations, there can be no proper relationship envisaged between the transcendent causality of God operating in Christ and the created, active cooperative acts with this grace. While building up both a metaphysical and a theological case against Barth's criticisms... (shrink)

How do multiple reasons combine to support a conclusion about what to do or believe? This question raises two challenges: How can we represent the strength of a reason? How do the strengths of multiple reasons combine? Analogous challenges about confirmation have been answered using probabilistic tools. Can reductive and nonreductive theories of reasons use these tools to answer their challenges? Yes, or more exactly: reductive theories can answer both challenges. Nonreductive theories, with the help of a (...) result in confirmation theory, can answer one, and there are grounds for optimism that they can answer the other. (shrink)

What is wrong with ad hoc hypotheses? Ever since Popper’s falsificationist account of adhocness, there has been a lively philosophical discussion about what constitutes adhocness in scientific explanation, and what, if anything, distinguishes legitimate auxiliary hypotheses from illicit ad hoc ones. This paper draws upon distinct examples from pseudoscience to provide us with a clearer view as to what is troubling about ad hoc hypotheses. In contrast with other philosophical proposals, our approach retains the colloquial, derogative meaning of adhocness, and (...) calls attention to the way in which the context of a theoretical move bears on the charge of adhocness. We also discuss the role of motivations implicit in the concept of adhocness, and the way ad hoc moves draw on theory-internal rationalizations. (shrink)

The problem of teleology is one of the major challenges for theoretical biology and, in general, for every philosophy of life. The debate about the nature of the organism and its difference from inorganic matter cannot come to terms with, at one point or another, the problem that arises from the unavoidable impression of teleology exhibited by the living itself. In this respect, the advantages that a systematic thinker such as Hartmann can offer to the philosophical analysis of life are (...) remarkable. The first discussion by Hartmann on the problem of causality can be found in Philosophische Grundfragen der Biologie (1912), a work which, however accurate, takes a predominantly Kantian and neo-Kantian approach, and cannot rely on the original and fecund tools of Hartmann’s mature stratified ontology. Therefore, the present contribution will focus on Hartmann’s ontological works, in particular his Philosophie der Natur: Abriss der speziellen Kategorienlehre (1950), in order to highlight and discuss the theoretical advantages they present. In particular, the validity of Hartmann’s ontological approach will be revealed by three key points: 1) a careful categorial distinction between different forms of determination, and even of causality, present in nature; 2) the refusal of vitalism, with the resolute limitation of finality in the proper sense to human conscious action; and 3) a great openness to the possibility that the living could be a third realm, governed by an autonomous modality of determination whose nature has yet to be discovered.

A dialogue-based analysis of informal fallacies does not provide a fully adequate explanation of our intuitions about what is wrong with ad baculum and of when it is admissible and when it is not. The dialogue-based analysis explains well why mild, benign threats can be legitimate in some situations, such as cooperative bargaining and negotiation, but does not satisfactorily account for what is objectionable about more malicious uses of threats to coerce and to intimidate. I propose an alternative deriving partly (...) from virtue theory in ethics and epistemology and partly from Kantian principles of respect for persons as ends-in-themselves. I examine some specific kinds of social relations, e.g., parent-child and partner relationships, and ask what kinds of threats are permissible in these relationships and especially what is wrong with the objectionable threats. My explanation is framed in terms of the good character and contributing virtues of the ideal parent or partner on the one hand, and the bad character and contributing vices of the abusive parent or violent partner on the other. This analysis puts the discussion of theats in the context of virtue theory, of human flourishing, and of the kind of social relations it is best to have. In general, what's wrong with argumentum ad baculum should be explained in terms of the intentions, purposes, and character of threateners, and the differences in intentions and purposes for which threats are made. The characters of those who make the threats will provide the criteria for distinguishing benign and malicious threats. (shrink)

Evolutionary psychologists should go beyond research on individual differences in attitudes and focus more on detailed models of psychological mechanisms. We argue for complementing attitude research with agent-based computational modeling of mate choice. Agent-based models require detailed specification of individual choice mechanisms that can be evaluated in terms of both their psychological plausibility and the population-level outcomes they produce.

Using national opinion survey data, this research addressed claims in political science that the American electorate is either poorly informed or dependent on party label cues.

Until now, philosophical debate about human embryonic stem cell (hESC) research has largely been limited to its ethical dimensions and implications. Although the importance and urgency of these ethical debates should not be underestimated, the almost undivided attention that mainstream and feminist philosophers have paid to the ethical dimensions of hESC research suggests that the only philosophically interesting questions and concerns about it are by and large ethical in nature. My argument goes some distance to challenge the assumption that ethical (...) considerations alone must be foregrounded in philosophical discussions about hESC research by introducing a critical stance on the epistemological and ontological assumptions that underlie and condition it. A central aim of the paper is to show how Foucault's insights into knowledge-power, taken in combination with Hacking's claims about styles of reasoning, can make these assumptions evident, as well as cast light on their potentially deleterious implications for disabled people. Arguing in this way also enables me to draw out constitutive effects of research on stem cells, that is, to indicate how the discursive practices surrounding research on stem cells, as well as the technology itself, contribute to the constitution of impairment.

In his recent writings on religion and secularization, Habermas has challenged reason to clarify its relation to religious experience and to engage religions in a constructive dialogue. Given the global challenges facing humanity, nothing is more dangerous than the refusal to communicate that we encounter today in different forms of religious and ideological fundamentalism. Habermas argues that in order to engage in this dialogue, two conditions must be met: religion must accept the authority of secular reason as the fallible results (...) of the sciences and the universalistic egalitarianism in law and morality; and conversely, secular reason must not set itself up as the judge concerning truths of faith. This argument was developed in part as a reaction to the conception of the relation between faith and reason formulated by Pope Benedict XVI in his 2006 Regensburg address. In 2007 Habermas conducted a debate, under the title ‘An Awareness of What Is Missing', with philosophers from the Jesuit School for Philosophy in Munich. This volume includes Habermas's essay, the contributions of his interlocutors and Habermas's reply to them. It will be indispensable reading for anyone who wishes to understand one of the most urgent and intractable issues of our time. (shrink)

This paper considers some aspects of the early conception and use of the infinite in ancient Greece, in the spirit of recent results in the history of ancient mathematics. It follows aspects of the practice of reasoning ad infinitum from the extant corpus of and about Zeno of Elea up to early Hellenistic examples in Aristotle and Euclid. Starting with the idea of ‘reasoning from indefinite iteration’, based on the metalogical recognition of the unachievability of an inference process, it identifies (...) several different classes of more or less sophisticated arguments that make use of this idea, and examines the logical devices and notions required for their acceptance in the philosophical practice. Those include ‘Infinite regress’ properly speaking, where Non-Contradiction is used in the formation of indirect infinitary arguments. (shrink)

In the section of the Antinomy of pure Reason Kant presents three notions of infinity. By investigating these concepts of infinity, this paper highlights important ‘building blocks’ of the structure of the mathematical antinomies, such as the ability of reason of producing ascending and descending series, as well as the notions of given and givable series. These structural features are discussed in order to clarify Ernst Zermelo’s reading of Kant’s antinomy, according to which the latter is deeply rooted in the (...) tendency of the mind of producing “creative progress” and “inclusive closure”. The aim of this paper is to explain in which sense and why Kant’s treatment of the antinomies attracts the attention of Zermelo in the early 1900s and which aspects of his second axiomatic system have been inspired by Kant’s philosophy. Thus, by reading Kant’s antinomy ‘through Zermelo’s eyes’—with emphasis on the concept of regressive series in indefinitum and on that of regressive series ad infinitum – this paper identifies the echoes of Kant’s work in the making of the ZFC set theory.

This concise text treats logic as a tool, “generated so that half the work involved in thinking is done for you by somebody else (the rules and laws of the logic).” Gabbay explains in a clear and careful manner how formal features of, and formal relations between, ordinary declarative sentences are captured by the systems of propositional and predicate logic.

The paper starts by reflecting on what senior engineering students don't know how to do when they confront a real-world project in an industrially sponsored senior design project. Seven, largely qualitatively, skills are found to be lacking: questioning, labeling, qualitatively modeling, decomposing, measuring, ideating, and communicating. These skills, some of the most important critical and creative thinking skills in the arsenal of modern civilization, are termed "the missing basics" and contrasted with what engineering faculty usually call "the basics." The (...) paper critically examines the term "the basics" and other terms that are conceptual hurdles to fundamental reassessment of engineering education at this time. The paper concludes that the engineering academy is stuck in a Kuhnian paradigm born in the cold war, that the reflexive belief in the superiority of math, science, and engineering science to the exclusion of other topics is not itself scientific, and that the use of tired code words is not an argument or a rational defense of a paradigm that may have outlived its usefulness. The paper concludes by highlighting the role philosophy can play in clearing away the conceptual confusion, thereby permitting a more reasoned conversation on the needs of engineering education in our times.

Many philosophers have claimed that we might do well to adopt a hybrid theory of well-being: a theory that incorporates both an objective-value constraint and a pro-attitude constraint. Hybrid theories are attractive for two main reasons. First, unlike desire theories of well-being, hybrid theories need not worry about the problem of defective desires. This is so because, unlike desire theories, hybrid theories place an objective-value constraint on well-being. Second, unlike objectivist theories of well-being, hybrid theories need not worry about (...) being overly alienating. This is so because, unlike objectivist theories, hybrid theories place a pro-attitude constraint on well-being. However, from the point of view of objectivists, hybrid theories are not objectivist enough, and this can be seen clearly in missing-desires cases. For instance, hybrid theories entail that, if someone lacks the desire for health, then health is not a component of her well-being. This, objectivists say, is implausible. It is obvious, objectivists say, that someone’s life goes better for herself inasmuch as she is healthy, and hence that health is a component of her welfare. This paper focuses on the missing-desires objection (as leveled by objectivists) to hybrid theories of well-being. My argument is that the missing-desires objection can be answered in a way that is generally convincing and, in particular, in a way that pays a good deal of respect to objectivist intuitions about well-being. My hope, then, is that this paper will help to persuade objectivists about well-being to become hybrid theorists. (shrink)

Popper's account of refutation is the linchpin of his famous view that the method of science is the method of conjecture and refutation. This thesis critically examines his account of refutation, and in particular the practice he deprecates as avoiding a refutation. I try to explain how he comes to hold the views that he does about these matters; how he seeks to make them plausible; how he has influenced others to accept his mistakes, and how some of the ideas (...) or responses to Popper of such people are thus similarly mistaken. I draw some distinctions necessary to the provision of an adequate account of the so-called practice of avoiding a refutation, and try to rid the debate about this practice of at least one red herring. I analyse one case of 'avoiding' a refutation in detail to show how the rationality of scientific practice eludes both Popper and many of his commentators. Popper's skepticism about contingent knowledge prevents him from providing an acceptable account of contingent refutation, and so his method is really the method of conjecture and conjecture. He cannot do without the concepts of knowledge and refutation, however, if his account of science is to be plausible or persuasive, and so he equivocates between, amongst other things, refutation as disproof and refutation as the weaker notion of discorroboration. I criticise David Stove's account of this matter, in particular to show how he misses this point. An additional advantage Popper would secure from this equivocation is that if refutations were mere discorroborations they would be easier to achieve, and hence more common in science, than is the case. On Popper's weak notion of refutation, it would be possible to refute true theories since corroboration does not entail truth. There are two other related doctrines Popper holds about refutation which, if accepted, make some refutations seem easier to obtain than is the case. I call these doctrines 'Strong Popperian Falsificationism' (SPF) and 'Weak Popperian Falsificationism' (WPF). SPF is the false doctrine that if a prediction from some theory is refuted then that theory is refuted. Popper does not always endorse SPF. In particular, when confronted with a counterexample to it, he retreats to WPF, which is the false doctrine that if a prediction from some theory is refuted then that theory is prima facie refuted. WPF , or even SPF, can seem plausible if one has in mind predictions derived from theories in strong or conclusive tests of those theories, which I suggest Popper characteristically does. v Popper is disposed to describe any such case of predictive failure which does not lead to the refutation of the theory concerned as one in which that refutation has been avoided. To reinforce his portrayal of the refutation, or the attempted refutation, of major scientific theories as the rational core of scientific practice, Popper treats the so-called practice of avoiding a refutation as untypical of science, and much so-called avoidance he dismisses as unscientific or pseudo-scientific. I argue that his notion of avoiding a refutation is incoherent. Popper is further driven to believe that such avoidance is possible, however, because he conflates sentences with propositions and propositions with propositional beliefs. Also, he wishes to avoid being saddled with the relativisim that is a consequence of his weak account of refutation as discorroboration. Popper believes that ad hoc hypotheses are the most important of the unscientific means of avoiding a refutation. I argue that his account of such hypotheses is also incoherent, and that several hypotheses thought to be ad hoc in his sense are not. Such hypotheses appear to be so largely because of Popper's use of rhetoric and partly because these hypotheses are unacceptable for other reasons. I conclude that to know that a hypothesis is ad hoc in Popper's sense does not illuminate scientific practice. Popper has also attempted to explicate ad hocness in terms of some undesirable, or allegedly undesirable, properties of hypotheses or the explanations they would provide. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which is not. In the former case I argue that non-circularity is clearly preferable to non-ad hocness as a criterion for a satisfactory explanation or explanans, as the case may be, and in the latter case that Popper is barking up the wrong tree. Some cases of so-called avoidance are obviously not unscientific. The discovery of Neptune from a prediction based on the reasonable belief that there were residual perturbations in the motion of Uranus is an important case in point, and one that is much discussed in the literature. The manifest failure of astronomers to account for Uranus's motion did not lead to the refutation of Newton's law of gravitiation, yet significant scientific progress obviously did result. Retreating to WPF, Popper claims that Newton's law was prima facie refuted. In general, astronomers have never shared this view, and they are correct in not doing so. I argue that the law of gravitation would have been prima facie refuted only if there had been good reason at the time to believe as false what is true, namely, that an unknown trans-Uranian planet was the cause of those Uranian residuals. Knowledge of the trans-Uranian region was then so slight that it was merely a convenient assumption, one which there was little reason to believe was false, that the known influences on Uranus's motion were the only such influences. I conclude that in believing vi or supposing that it was this assumption that was false, rather than the law of gravitation, Leverrier and Adams, the co-predictors of Neptune, were acting rationally and intelligently. Popper's commentators offer a variety of accounts of the alleged practice of avoiding a refutation, and of this case in particular. I analyse a sample of their accounts to show how common is the acceptance of some of Popper's basic mistakes, even amongst those who claim to reject his falsificationism, and to display the effects on their accounts of this acceptance of his mistakes. Many commentators recognize that anomalies are typically dealt with by changes in the boundary conditions or in other of the auxiliary propositions employed. Where many still go wrong, however, is in retaining the presupposition of WPF which encouraged Popper to hold the contradictory view about anomalies in the first place. Thus Imre Lakatos and others, for example, have developed a 'siege mentality' about major scientific theories; they see them as under continual threat of refutation from anomalies, and so come to believe that dogmatism is essential in science if such theories are to survive as they do. I examine various such doomed attempts to reconcile Popper with the history of science. It is a common failure in this literature to conflate or to fail to see the need to distinguish a belief from a supposition, and an epistemic reason from a pragmatic reason. I argue that only if one does draw these distinctions can one give an adequate account of how anomalies are rationally dealt with in science. The other important strand in Popper's thinking about 'avoidance' of refutation which has seriously misled some of his commentators is his unfounded belief in the dangers of ad hoc hypotheses. I examine the accounts that a sample of such commentators provide of the trans-Uranian planet hypotheses of Leverrier and Adams. These commentators imply or assert what Popper only hints at, namely, that there is something fishy about this hypothesis. I provide a further defence of the rationality of entertaining this hypothesis at the time. I conclude with a few remarks about Popper's dilemma in respect of scientific practice and his long standing emphasis on refutations. (shrink)

How can black feminist and women of color feminist theoretical interventions help create frameworks for discerning agentic action in the context of power, oppression, and violence? In this paper, I explore the social dimension of agency and argue that intention is not just authored by the agent as a function of practical reasoning, but is also socially authored through others' discernment and translation of her action. Further, when facilitated by reasoning designed to reinforce and rationalize systems of domination, social authoring (...) systematically distorts the intentions of some agents. Although some theorists have argued that those agents whose intentions are not recognized by others are forced to exercise a diminished agency, I contend that this account obscures agency that is practiced despite or through conditions of oppression. As an alternative, I propose that feminist of color theory that examines the structural and existential erasures of women of color maps a conceptual space to help us better discern agentic action that is practiced by those subjects whose acts are defined away from them.

Diseases of complex origin have a component of quantitative genetics that contributes to their susceptibility and phenotypic variability. However, after several studies, a major part of the genetic component of complex phenotypes has still not been found, a situation known as “missing heritability.” Although there have been many hypotheses put forward to explain the reasons for the missing heritability, its definitive causes remain unknown. Complex diseases are caused by multiple intermediate phenotypes involved in their pathogenesis and, very (...) often, each one of these intermediate phenotypes also has a component of quantitative inheritance. Here we propose that at least part of the missing heritability can be explained by the genetic component of intermediate phenotypes that is not detectable at the level of the main complex trait. At the same time, the identification of the genetic component of intermediate phenotypes provides an opportunity to identify part of the missing heritability of complex diseases. (shrink)

Criminal law abolitionists claim that legal punishment cannot be morally justified and that we should therefore abolish criminal law. While this is still a minority position in the current debate, the number of proponents has been increasing, and even opponents have developed a certain degree of sympathy for such claims in recent years. Yet one of the reasons many remain hesitant regarding the abolition of criminal law appears to be the lack of a thought-through alternative, in addition to abolitionists (...) disagreeing considerably amongst themselves on what an alternative should look like. I will call this the missing alternative objection. To address this central concern, I will argue in this paper that the most prominent versions of abolitionism actually converge on the same alternative core to criminal law — even though they are driven by vastly different motivations. This core that current abolitionist theories converge on is two-fold: first, the claim that the state should compel offenders to provide restitution for the victim; second, the claim that restorative processes should be used wherever possible when addressing criminal wrongdoing. This common core is enough to reject the missing alternative objection. (shrink)

In his influential work on critical argumentation, Douglas Walton explains how to judge whether an argumentum ad verecundiam is fallacious or legitimate. He provides six critical questions and a number of ancillary sub-questions to guide the identification of reasonable appeals to authority. While it is common for informal logicians to acknowledge the role of bias in sampling procedures and hypothesis confirmation , there is a conspicuous lack of discourse on the effect of identity prejudice on judgments of authority, even though (...) this is a well-documented factor in attributing credibility, expertise, trustworthiness, and professional competence to oppressed groups. This could result in faulty judgments of ad verecundiam fallacy. Focusing on gender bias, I review recent works in feminist epistemology—particularly those of Miranda Fricker and Helen Longino —to develop three gender-based critical questions to supplement Walton’s original list of six. This addition will help us to identify erroneous dismissals of appeals to authority based on epistemic injustice and epistemic irresponsibility on the part of the speaker or knowledge community. This project promotes the overlapping aims of feminist epistemology and informal logic. (shrink)

This article draws on the free‐text commentaries from trans‐Tasman studies that used the MISSCARE questionnaire to explore the reasons why nurses miss care. In this paper, we examine the idea that nurses perpetuate a self‐effacing approach to care, at the expense of patient care and professional accountability, using what they describe as the art of nursing to frame their claims of both nursing care and missed nursing care. We use historical dialogue alongside a paradigmatic analysis to examine why nurses (...) allow themselves to continue working within settings that put their professional/personal selves aside in an attempt to deliver care within constraints that make completing care an impossible task. The findings suggest an ambivalence and conflict confront nurses attempting to provide care within the New Public Management environment. This can be seen in the tensions that draw a line between care as an art, and care as a financial target, juxtaposed with the inherent clash of values arising from the way nursing care is conceptualised within two contradictory paradigms.

Background: Determination of the factors affecting missed nursing care and the impact of ethical leadership is important in improving the quality of care. Aim: This study aims to determine the missed nursing care and its relationship with perceived ethical leadership. Research design: A cross-sectional study. Participants and research context: The sample consisted of 233 nurses, of whom 92.7% were staff nurses and 7.3% were charge nurses, who work in three different hospitals in Turkey. The study data were collected using a (...) personal and professional characteristics data form, the Missed Nursing Care Survey, and the Ethical Leadership Scale. Ethical considerations: The study was approved by the non-interventional ethics committee of Dokuz Eylül University Ethics Committee for Noninvasive Clinical Studies. All participants’ written and verbal consents were obtained. Findings: The most missed nursing care practices were ambulation, attending interdisciplinary care conferences, and discharge planning. According to the logistic regression analysis, sex, the number of patients that the nurse is in charge of giving care, the number of patients discharged in the last shift, and satisfaction with the team were determined as factors affecting missed care. No significant relationship was found between ethical leadership and missed nursing care, and a weak but significant relationship was found between the clarification of duties/roles subscale and missed nursing care. Discussion: Ethical leaders should collaborate with policy-makers at an institutional level to particularly achieve teamwork that is effective in the provision of care, to control missed basic nursing care, and to organize working hours and at the country level to determine roles and to increase the workforce. Conclusion: The results of this study contribute to the international literature on the most common type of missed nursing care, its reasons, and the relationship between the missed care and ethical leadership in a different cultural context.

Tractatus 4.024 inspired the dominant semantics of our time: truth-conditional semantics. Such semantics is focused on possible worlds: the content of p is the set of worlds where p is true. It has become increasingly clear that such an account is, at best, defective: we need an ‘independent factor in meaning, constrained but not determined by truth-conditions’ (Yablo 2014, p. 2), because sentences can be differently true at the same possible worlds. I suggest a missing comment which, had it (...) been included in the Tractatus, would have helped semantics get this right from the start. This is my 4.0241: ‘Knowing what is the case if a sentence is true is knowing its ways of being true’: knowing a sentence’s truth possibilities and what we now call its topic, or subject matter. I show that the famous ‘fundamental thought’ that ‘the “logical constants” do not represent’ (4.0312) can be understood in terms of ways-based views of meaning. Such views also help with puzzling claims like 5.122: ‘If p follows from q, the sense of “p” is contained in the that of “q”’, which are compatible with a conception of entailment combining truth-preservation with the preservation of topicality, or of ways of being true.

Wireless ad hoc communication on the nanoscale will require thinking outside of the traditional radio spectrum. New applications will utilize new forms of wireless communication channels. For example, nanoscale communication will enable precise mechanisms for directly interacting with cells in vivo. Information may be sent to and from specific cells within the body, allowing detection and healing of diseases on the cellular scale. From a medical standpoint, the use of current wireless techniques to communicate with implants is unacceptable for many (...) reasons, including bulky size, inability to use magnetic resonance imaging after implantation, potential radiation damage, surgical invasiveness, need to recharge/replace power, post-operative pain and long recovery times, and reduced quality of life for the patient. Better, more humane in vivo implant communication is needed. Development of both biological and engineered nanomachines is progressing; such machines will need to communicate [1]. Unfortunately, networking vast collections of nanoscale sensors and robots using current techniques, including wireless techniques, is not possible without communication mechanisms that exceed nanoscale volumes.

All of us, including scientists, make judgments about what is true or false, probable or improbable. And in the process, we frequently appeal to concepts such as evidential support or explanation. Bayesian philosophers of science have given illuminating formal accounts of these concepts. This paper aims to follow in their footsteps, providing a novel formal account of various additional concepts: the likelihood-prior trade-off, successful accommodation of evidence, ad hocness, and, finally, consilience—sometimes also called “unification”. Using these accounts, I also provide (...) a new Bayesian analysis of how someone such as Charles Darwin hypothetically could have reasoned in favor of evolution over special creationism. Lastly, I explore how these accounts relate to other topics and accounts in philosophy, and I chart out some areas for further research. (shrink)

Karl Popper defines an ad hoc hypothesis as one that is introduced to immunize a theory from some (or all) refutation but which cannot be tested independently. He has also attempted to explicate ad hocness in terms of certain other allegedly undesirable properties of hypotheses or of the explanations they would provide, but his account is confused and mistaken. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which need not be. (...) In the former case, I argue that non-circularity is in any event preferable to non-ad hocness as a necessary condition for a satisfactory explanation or an explanans, as the case may be, and I try to sort out various persistent errors surrounding this comparison. In the latter case, I suggest that Popper is barking up the wrong tree, that important scientific progress sometimes does consist in just such reductions in empirical content as he proscribes. This provides a further reason for not taking ad hoc hypotheses as Popper conceives them to pose the danger for science he believes they do. (shrink)

Nowadays, the quality standards of higher education institutions pay special attention to the performance and evaluation of the students. Then, having a complete academic record of each student, such as number of attempts, average grade and so on, plays a key role. In this context, the existence of missing data, which can happen for different reasons, leads to affect adversely interesting future analysis. Therefore, the use of imputation techniques is presented as a helpful tool to estimate the value (...) of missing data. This work deals with the academic records of engineering students, in which imputation techniques are applied. More specifically, it is assessed and compared to the performance of the multivariate imputation by chained equations methodology, the adaptive assignation algorithm based on multivariate adaptive regression splines and a hybridization based on self-organisation maps with Mahalanobis distances and AAA algorithm. The results show that proposed methods obtain successfully results regardless the number of missing values, in general terms. (shrink)

We introduce a methodology whereby an arbitrary logic system L can be enriched with temporal features to create a new system T(L). The new system is constructed by combining L with a pure propositional temporal logic T (such as linear temporal logic with Since and Until) in a special way. We refer to this method as adding a temporal dimension to L or just temporalising L. We show that the logic system T(L) preserves several properties of the original temporal (...) logic like soundness, completeness, decidability, conservativeness and separation over linear flows of time. We then focus on the temporalisation of first-order logic, and a comparison is make with other first-order approaches to the handling of time. (shrink)

The extent to which we generalize a novel property from a sample of familiar instances to novel instances depends on the sample composition. Previous property induction experiments have only used samples consisting of novel types (unique entities). Because real‐world evidence samples often contain redundant tokens (repetitions of the same entity), we studied the effects on property induction of adding types and tokens to an observed sample. In Experiments 1–3, we presented participants with a sample of birds or flowers known (...) to have a novel property and probed whether this property generalized to novel items varying in similarity to the initial sample. Increasing the number of novel types (e.g., new birds with the target property) in a sample produced tightening, promoting property generalization to highly similar stimuli but decreasing generalization to less similar stimuli. On the other hand, increasing the number of tokens (e.g., repeated presentations of the same bird with the target property) had little effect on generalization. Experiment 4 showed that repeated tokens are encoded and can benefit recognition, but appear to be given little weight when inferring property generalization. We modified an existing Bayesian model of induction (Navarro, Dry, & Lee, 2012) to account for both the information added by new types and the discounting of information conveyed by tokens. (shrink)

This paper contends that Kant’s argument in the Refutation of Idealism section of the Critique of Pure Reason misses a step which allows Kant to move illicitly from inner experience to outer objects. The argument for persistent outer objects does not comprehensively address the skeptic’s doubts as it leaves room for the question about the necessary connection between representations and outer objects. A second fundamental issue is the ability of transcendental idealism to deliver the account of outer objects, as required (...) by the Refutation of Idealism itself. (shrink)

In THE MISSING MOMENT a distinguished molecular biologist explores the nature of time and argues for a radical rethinking of how time affects our sense of self, our mortality, and the future of science and medicine. Only in the past few years have we learned enough about the brain for this remarkable book to be written. We know now that our brains continually filter the present through memories and emotions of the past. In fact, strictly speaking, we live in (...) the past: since it takes the brain a second to process perceptions, what we think is the present actually happened a second ago. We also know where and how the unconscious operates and how painful memories are repressed; repression is not a psychological defect but an evolutionary necessity for our species. All thought, even the most rational, is permeated with unconscious feelings, fears, and emotions. Scientists, like the rest of us, make choices for reasons they don't understand. Thus the direction of scientific research is driven by private demons, not public needs. We can see this in medical science, where doctors develop the tools to diagnose genetic diseases they cannot cure, bringing pain rather than comfort to patients. Today science can do more good than ever before, and it can also do more harm. The time has come for scientists and others to abandon the notion that there is any such thing as the disinterested pursuit of truth. Instead, they must strive for a therapeutic self-awareness of their unconscious agendas and work for larger goals than personal immortality. (shrink)

Artificial general intelligence is not a new notion, but it has certainly been gaining traction in recent years, and academic as well as industry resources are redirected to research in AGI. The main reason for this is that current AI techniques are limited as they are designed to operate in specific problem-domains, following meticulous preparation. These systems cannot operate in an unknown environment or under conditions of uncertainty, reuse knowledge gained in another problem domain, or autonomously learn and understand the (...) problem-domain. We shall call AI systems capable of such feats artificial general intelligent systems. The three tasks of this paper are to provide a working definition of the term AGI, examine the “missing G”, i.e., the set of abilities that current AI systems lack and whose implementation will result in a basic AGI system, and consider different approaches, including a hybrid one, to a comprehensive solution for an AGI.
