High-definition transcranial direct current stimulation is a valid brain stimulation technology to optimize cognitive function. Recent evidence indicates that single anodal tDCS session enhances attention; however, the variation in attention produced by repeated anodal HD-tDCS over a longer period of time has not been explored. We examined the modulation of attention function in healthy young participants who received repeated HD-tDCS sustained for 4 weeks. The results showed a robust benefit of anodal HD-tDCS on executive control and psychomotor efficiency, but not (...) on orienting, alerting, or selective attention ; the benefit increased successively over 4 weeks; and the enhancement on executive control of each week was significant compared to baseline in the anodal group. In addition, the subjects’ performances on the test of executive control and psychomotor efficiency gradually restored to the initial level in the sham group, which appeared obviously from week 3, but the improvement of attention in the anodal group was persistent. We conclude that repeated anodal HD-tDCS provides a positive benefit on executive control and psychomotor efficiency and has obvious accumulative effect after 9 or more times intervention compared to sham HD-tDCS. Additionally, our findings might provide pivotal guidance for the formulation of a strategy for the use of repeated anodal HD-tDCS to modulate on attention function. (shrink)

Schizophrenia is a serious mental illness characterized by a disconnection between brain regions. Transcranial magnetic stimulation is a non-invasive brain intervention technique that can be used as a new and safe treatment option for patients with schizophrenia with drug-refractory symptoms, such as negative symptoms and cognitive impairment. However, the therapeutic effects of transcranial magnetic stimulation remain unclear and would be investigated using non-invasive tools, such as functional connectivity. A longitudinal design was adopted to investigate the alteration in FC dynamics using (...) a dynamic functional connectivity approach in patients with schizophrenia following high-frequency repeated transcranial magnetic stimulation with the target at the left dorsolateral prefrontal cortex. Two groups of schizophrenia inpatients were recruited. One group received a 4-week high-frequency rTMS together with antipsychotic drugs, while the other group only received antipsychotic drugs. Resting-state functional magnetic resonance imaging and psychiatric symptoms were obtained from the patients with schizophrenia twice at baseline and after 4-week treatment. The dynamics was evaluated using voxel- and region-wise FC temporal variability resulting from fMRI data. The pattern classification technique was used to verify the clinical application value of FC temporal variability. For the voxel-wise FC temporary variability, the repeated measures ANCOVA analysis showed significant treatment × time interaction effects on the FC temporary variability between the left DLPFC and several regions, including the thalamus, cerebellum, precuneus, and precentral gyrus, which are mainly located within the cortico-thalamo-cerebellar circuit. For the ROI-wise FC temporary variability, our results found a significant interaction effect on the FC among CTCC. rTMS intervention led to a reduced FC temporary variability. In addition, higher alteration in FC temporal variability between left DLPFC and right posterior parietal thalamus predicted a higher remission ratio of negative symptom scores, indicating that the decrease of FC temporal variability between the brain regions was associated with the remission of schizophrenia severity. The support vector regression results suggested that the baseline pattern of FC temporary variability between the regions in CTCC could predict the efficacy of high-frequency rTMS intervention on negative symptoms in schizophrenia. These findings confirm the potential relationship between the reduction in whole-brain functional dynamics induced by high-frequency rTMS and the improvement in psychiatric scores, suggesting that high-frequency rTMS affects psychiatric symptoms by coordinating the heterogeneity of activity between the brain regions. Future studies would examine the clinical utility of using functional dynamics patterns between specific brain regions as a biomarker to predict the treatment response of high-frequency rTMS.

Background Changes in policies and practices related to repeat cesareans and home birth in the U.S. have been influenced by different interpretations of the risk of poor outcomes. Methods This article examines two cases—vaginal birth after cesarean (VBAC) and home birth to illustrate how an emphasis on relative over absolute risk has been used to characterize outcomes associated with these practices. The case studies will rely on reviews of the research literature and examination of data on birth trends and (...) outcomes. Results Childbirth involves some unique challenges in assessing health risks, specifically the issues of: (1) timing of risks (lowering health risk in a current birth can increase it in subsequent births); (2) the potential weighing of risks to the mother’s versus the infant’s health; (3) the fact that birth is a condition of health and many of the feared outcomes (for example, symptomatic uterine rupture) involve very low absolute risk of occurrence; and (4) a malpractice environment that seizes upon those rare poor outcomes in highly publicized lawsuits that receive widespread attention in the clinical community. In the cases of VBAC and home birth, the result has been considerable emphasis on relative risks, typically an adjusted odds ratio, with little consideration of absolute risks. Conclusion Assessments of the safety of interventions in childbirth should involve careful consideration and communication of the multiple dimensions of risk, particularly a balancing of relative and absolute risks of poor health outcomes.

The general and sports psychology research is limited regarding the difference between the effects of verbal encouragement or compliment methods during high-intensity functional exercise testing. The purpose of this study was to explore the effects of VE and compliments on the performance of the repeated change-of-direction sprint test. A total of 36 male students in secondary school participated voluntarily in the study. They were divided equally into three homogeneous groups [VE group, compliment group, and control group) and performed a standardized (...) one repetition RCOD. The RCOD test consisted of a 100°change in the direction at every 4 m. Outcomes included performance indices, rating of perceived exertion, and feeling scale scores. VE and the compliment increased the performance indices and RPE compared with the control group. In conclusion, VE during the exercise testing would be more beneficial for optimal performance and RPE compared with the compliment and control groups. However, the moods, during RCOD, reproduce more positively during compliment conditions than the VE and control groups. (shrink)

This note on Propertius 4.7 argues that Cynthia, repeatedly cast in the role of the poet's Muse, rejects the burden of inspiration through a learned choice of words (non tamen insector, 4.7.49). The verb insector constitutes a clear reference to the invocation of the Camena in Livius Andronicus and of the Muse in Ennius. Cynthia recalibrates the parlance of poetic inspiration to end her relationship with Propertius, both as his puella and as his Muse.

"This volume offers a new translation of the Neoplatonist philosopher Simplicius' commentary on the chapters concerning place and time in Aristotle's Physics, Book Four. Written after the closing of the Athenian Neoplatonist school in A.D. 529, the commentary clarifies the structure and meaning of Aristotle's arguments and provides a rich account of 800 years of interpretation." "Surprisingly, in the first five chapters of Book Four Aristotle shows place as two-dimensional: one's place is the two-dimensional inner surface of one's surroundings. He (...) also suggests that the upward motion of air and fire and the downward motion of earth and water are partly explained by the natural places to which they tend. Place thus has power (dunamis) of its own. In his last five chapters, Aristotle argues that if time did not entail change its passage would be undetectable, and that time, by definition countable, requires the existence of conscious beings to do the counting. Among the many relevant views that Simplicius records are those of Galen, who attacks this claim, and of Eudemus, who rebuts the Pythagorean theory that history will repeat itself exactly. J. O. Urmson's translation serves as a companion to his earlier translation of the Corollaries on Place and Time, in which Simplicius sets forth his own views as distinct from those of Aristotle." "A major sourcebook for the interpretation of Aristotle, this volume will be welcomed by scholars and students in the fields of classics, ancient philosophy, ancient history, and medieval studies."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Microtubules are cylindrical lattice polymers of the protein tubulin which organize purposeful activities in brain neurons and all eukaryotic cells. Here we report that microtubules behave as 'fractal time crystals', characterized by self-similar resonance oscillations, 'clocks within clocks' in a nested hierarchy of similar dynamics ('triplets-of-triplets') which repeat in hertz, kilohertz, megahertz, gigahertz, and terahertz frequencies. Megahertz triplets are detectable from human scalp beyond traditional EEG frequencies, and are suppressed by general anaesthetics, indicating a connection to consciousness. The Orch (...) OR theory proposes that consciousness results from quantum state reductions in microtubules consistent with time crystal behaviour. We identify distinct microtubule oscillatory subsystems responsible for collective oscillations in 1) kilohertz (tubulin C-termini), 2) megahertz (tubulin lattice phonons, polaritons), 3) gigahertz (microtubule hollow core ordered water oscillations), and 4) terahertz (aromatic π-electron transitions within tubulins). Life may require microtubule time crystals for spatio-temporal organization, collective intelligence, causal agency, feelings, and consciousness. Microtubules are the first biological time crystals to be proposed, and time crystal behaviour may be a fundamental property of living systems, connecting condensed matter physics, quantum biology, and the science of consciousness. We conclude with an assessment of our approach with Schneider and Bailey's target article, 'Superpsychism'. (shrink)

Stobaeus records a placitum where Empedocles says that the world is destroyed by the domination in turn of Love and of Strife. The placitum makes perfectly good sense in the context of Empedocles' belief that Love and Strife produce, in turn, a non-cosmic state of total unity (Love) and of total separation (Strife). But for over two hundred years scholars have been unable to hear that simple message. Sturz (1805) emended the text so as to make it fit the non-cyclical (...) interpretation of Empedocles that he had taken over from the pages of Tiedemann (1791). When Diels included Stobaeus' text in his edition of Aetius, in the "Doxographi graeci" (1879), he failed to remove the emendation, although his own reconstruction of the chapter heading in Aetius made the emendation impossible. Twenty years later, Diels saw the light, and printed Stobaeus' placitum, unemended, in his "Poetarum philosophorum fragmenta" (1901) and in successive editions of his "Fragmente der Vorsokratiker" (from 1903 onwards). But Kranz resurrected the emendation in the "Nachträge" to his sixth edition of the "Fragmente der Vorsokratiker" (1951). The emended placitum is used again by Uvo Hölscher (1965) to support a non-cyclical interpretation of Empedocles and is repeated in the latest collection of the fragments and testimonia (Brad Inwood, 1992). Hölscher fails to appreciate that the text that he uses to support his reconstruction is merely Sturz's translation into Greek of the non-cyclical interpretation of Empedocles proposed by Tiedemann at the end of the eighteenth century.

External validity refers to the generalization of research findings, either from a sample to a larger population or to settings and populations other than those studied. While definitions vary, discussions generally agree that experiments are lower in external validity than other methodological approaches. Further, external validity is widely treated as an issue to be addressed through methodological procedures. When testing theories, all measures are indirect indicators of theoretical constructs, and no methodological procedures taken alone can produce external validity. External validity (...) can be assessed through determining (1) the extent to which empirical measures accurately reflect theoretical constructs, (2) whether the research setting conforms to the scope of the theory under test, (3) our confidence that findings will repeat under identical conditions, (4) whether findings support the theory being tested, and (5) the confirmatory status of the theory under test. In these ways, external validity is foremost a theoretical issue and can only be addressed by an examination of the interplay between theory and methods. (shrink)

Operatiology (Japanese: *Sousa Genron*, 操作原論), derived from Noology (Japanese: *Chigaku*, 知学) through the three primitive notions of Ordo, Consensus, and Arbitrium, establishes the rank-3 minimal operational closure C⁽³⁾_Πd as the unique structure satisfying {A1, A2, A4} together with the Operational-Geometric Coupling. The companion paper on the top-down projection of mathematics establishes that algebra occupies the minimum-distance layer M₁ within the induced mathematical category M, delegating the complete algebraic identification to the present work. Both papers form part of the Cognitional Mechanics (...) (Japanese: *Chinou Rikigaku*, 知能力学) corpus. -/- This paper discharges that delegation in four stages. First, algebra is established as the M₁-layer: the unique minimum-distance projective structure from the operational substrate. Second, operational non-decomposability is derived from Axioms 1, 2, and 4: direct sum decomposition is excluded by Axiom 1, and non-trivial two-sided ideals are excluded via the maximality of I_Πd, establishing simplicity. Third, finite dimensionality is derived from the finite generator rank via an explicit saturation depth bound, and the Wedderburn-Artin theorem identifies the representation as Mₙ(D). Fourth, a bridge lemma connecting Πd-separation to eigenvalue structure establishes that Arbitrium forces D = ℂ, and the three-generator Πd-independence condition forces n = 3, yielding M₃(ℂ) as the unique minimal algebraic realisation of C⁽³⁾_Πd. -/- Version 2 adds Lemma 5.4 (faithfulness preservation under scalar extension), Lemma 5.5 (minimal faithful representation dimension of Mₙ(ℂ) is n), and a unit-element argument closing the irreducibility proof of Proposition 5.6 Step B without dimension-by-dimension case analysis. The Πd-separation axis correspondence is formalised as a separate lemma, and the exclusion of n = 2 and n ≥ 4 is strengthened.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Aquinas on Efficient Causation and Causal Powers by Gloria FrostBrian DaviesGloria Frost. Aquinas on Efficient Causation and Causal Powers. Cambridge: Cambridge University Press, 2022. Pp. 288. Hardback, $99.99; paperback, $32.99.Philosophers have often assumed that good philosophy discusses what X, Y, or Z is essentially. And Thomas Aquinas is someone who favors this way of proceeding. At one point in his writings, he modestly recognizes that he is at (...) a loss to explain what a house fly actually is. But he continually aims to tell us what such and such really is. And he does so when it comes to “cause” (causa). One might ask, “What is a cause?” or “What is causation?” Aquinas tries to answer these questions in theoretical ways that effectively add up to definitions of ‘cause’ and ‘causation.’Unfortunately, however, Aquinas never wrote a self-contained treatise on ‘cause’ and ‘causation.’ So, in order to fully understand what he says about these terms, one must pay attention to many texts scattered throughout his many writings, which may sound like bad news. The good news, however, is that Gloria Frost has now provided (for the first time, as far as I know) what amounts to an excellent and much-needed one-volume exposition of what Aquinas says about causation. More specifically, she has given us a fine scholarly work on the history of philosophy that focuses exegetically on what Aquinas calls “efficient” causation.Following Aristotle, Aquinas distinguishes between efficient, final, formal, and material causes (all of which are explanations of some kind). Frost has accurate things to say about Aquinas on material, formal, and final causes. But it is Aquinas on efficient causation that she homes in on in great detail—understandably, since Aquinas references this notion many times over and since what he means by ‘efficient causation’ seems in various ways to correspond to what “causation” is taken to be these days by both philosophers and nonphilosophers (few of whom are familiar with the phrases ‘material causation,’ ‘formal causation,’ and ‘final causation’). Frost rightly notes that Aquinas takes final causation to be bound up with efficient causation, and she explains the relation between them (chapter 4). Still, her focus is on Aquinas on efficient causation. As she writes, “I have combed through Aquinas’s corpus to find the most important passages about efficient causation and causal powers and using them as a basis, I reconstruct his views in a systematic way” (5).Chapter 1 begins this reconstruction by providing a general overview of Aquinas on efficient causation together with some historical background and context for understanding what he says on the topic. The chapter includes reference to views on causation differing from that of Aquinas and introductions to some of Aquinas’s sources concerning efficient causation. Chapters 2 through 6 expand on this overview in great detail with many quotations from Aquinas and a lot of cross-referencing within his writings. In these chapters, Frost expounds Aquinas on topics such as the distinction between per se and per accidens causation, temporality and causation, agent and patient, causation at a distance, actuality and potentiality, active power and passive power, and causation and necessitation. Chapter 7 deals with what Frost calls “non-paradigm” cases of efficient causation (191), which include absences (which Aquinas thinks can be efficient causes) and sine qua non efficient causation (which Aquinas does not think to be genuine efficient causation). Chapter 8 is devoted to instrumental causes, primary and secondary causation, and the causality of heavenly bodies. Each chapter begins with an introduction explaining what the core of the chapter is about. And each chapter ends with a summary of the findings of the chapter. This structure, which leads Frost to repeat herself a lot, might irritate some readers. I take [End Page 661] it to be didactically helpful. Nobody can complain that Frost has failed to make it clear what she takes Aquinas to be saying.Frost’s account of Aquinas on causation is exemplary. It is written with great clarity and avoids jargon. It draws heavily on texts of Aquinas and gives us an accurate account of what he thought about efficient causation (as well as... (shrink)

Generative Artificial intelligence (AI) technologies allow users to create novel images and modify existing images easily and rapidly. However, the training sets used to create the generative technologies may be biased; they may be primarily trained on images of White men (Karkkainen and Joo (2021) FairFace: face attribute dataset for balanced race, gender, and age for bias measurement and mitigation. Proceedings/IEEE Workshop on Applications of Computer Vision, 1547–1557. 10.1109/WACV48630.2021.00159, https://doi.org/10.1109/WACV48630.2021.00159 ). When the training is biased, the output will also be (...) biased. In this case, generating realistic faces of White men may be done with ease, but varying race, emotional expression, or gender may reduce realism. To determine the degree to which this bias exists, AI-generated faces were created using Leonardo.ai’s image-to-image algorithm, with two genders (man and woman), three races (Asian, Black, and White), and four emotional expressions (anger, fear, happiness, and sadness). N = 138 participants were presented with real and AI-generated faces and classified them as such. A 2 × 3 × 4 repeated measures ANOVA was run with sensitivity (d’) as the dependent variable. Participants were significantly better at identifying AI-generated faces of people of colour, more specifically, men of colour. Criterion values were also examined; participants had a bias towards classifying all faces except for those of White men as AI-generated, which they tended to classify as real. Our results support previous findings showing that demographic biases exist in generative AI tools and expand on those by showing how such biases interact with the emotional expression of the face.

This paper introduces a novel theoretical framework for representing the internal structure of numeral systems. This framework is based on labels and reading conventions for the entries and columns of an abacus, which suffice to describe numeral systems in a systematic way (including ones that have sub-bases or are irregular). The abacus represents, for example, a decimal place-value numeral with columns of equal height (labelled from 0 (empty) to 9) by reading the label of the greatest filled entry in each (...) column; and a Roman numeral with columns of different heights (1 and 4), repeating the label of each column as many times as it is filled. Owing to its uniform and abstract character, this abacus representation allows for the structural comparison of numeral systems across different representational formats (such as notational, verbal and body-based formats) and for the discussion of various irregularities of such systems.

Bypassing occurs on sharing platforms when users decide to finalize the exchange directly with each other and engage in tactics to circumvent the payment stage. While previous studies have focused on the antecedents associated with bypass practices, more research is needed to better understand the prevalence of bypassing, which bypass practices are enacted, which types of users bypass, and which do not. Using a mixed-methods design, we first conduct semi-structured interviews (N = 19) to identify several motivations behind bypass tactics (...) that complement the existing literature. We also establish four different bypassing behaviors: (1) paying the other peer directly, (2) transacting via another platform, (3) a combination of on- and off-platform booking, and (4) repeat transactions. Next, by carrying out cluster analysis on a sample of Airbnb users (N = 416), we uncover three groups of bypassers: serial maximizers, rookies, and safe players. Further analysis of Airbnb users who have never bypassed shows that they can be categorized into three additional segments: risk-conscious users, hassle-avoiders, and borderline bypassers. Each of these six groups corresponds to a specific profile, which we describe and characterize based on motivational, relational, and psychographic factors. This research provides an actionable segmentation framework that will help sharing platform managers develop tailored bypass mitigation strategies. (shrink)

The paper develops and argues the following theses: (1) Brentano’s theory of the four phases of philosophy was designed independently of Comte’s law of the three stages of thought. (2) Brentano took considerable care to underline the correspondence between the two theories. (3) The two theories start from different views of history: Comte’s theory encompasses the history of the fundamental positive sciences that developed in a linear, progressive and ascending direction, and is not affected by any lawlike occurring phases of (...) decay, but nevertheless knows stagnations. By contrast, Brentano’s theory refers primarily to the history of philosophy, though indirectly also to the fine arts. According to Brentano’s theory, the historical developments follow a cyclical course and know periods of scientific rise and decline, which repeat themselves. (4) Each theory provides a different strategy aiming at a fundamental reformation of philosophy. For Comte, the new philosophy must work positively and independently of the philosophical tradition. By contrast, Brentano advocates the view that philosophy, by its method, conducts empirical research analogous to research in natural science, and that it remains principally committed to the philosophical tradition. (5) Brentano’s “pure theoretical interest” involves not only positive-scientific components, but also metaphysical ones that are closely related to his general philosophical view. For this reason, he does not consider Comte and Mill as representatives of the new rising philosophical phase of his time, but as exponents of a hypercritical philosophy that sets aside the metaphysical questions and belongs to the second declining phase of philosophy, skepticism. (6) Despite its metaphysical dimension, Brentano’s psychology can be read as a contribution to positive philosophy in the sense of A. Comte and J. S. Mill, for the following reasons: (i) the objectives of Brentanian empirical psychology coincide with the objectives of the general positive view of scientific knowledge; (ii) the role played by Comte’s scale of sciences in grounding his empirical psychology; (iii) the methodological steps from PES that show what an important role Mill’s inductive-deductive model of science was to play in the methodological building of Brentano’s psychology. (7) By contrast, Brentano’s descriptive psychology constitutes the liberation of psychological research from the paradigm of positive science. (8) Chisholm’s interpretation of Brentano’s view of intuitive induction neglects the fact that, in Descriptive Psychology, Brentano uses induction in a narrower sense as well as induction in a broader sense.

Hobbes repeatedly expressed concerns about moral and political language, e.g., about the bad consequences of various uses and misuses of language. He did not simply focus on the consequences though. He also attempted to understand the problems, using the central semantic notion in his philosophy of language, signification. Hobbes, in both the Elements of Law and Leviathan, argues that a wide variety of terms – including ‘good’, ‘bad’, and the names of virtues and vices – have a double and inconstant (...) signification. This paper explores and explains that theory of Hobbes's. (In the course of the discussion, two other interpretations of Hobbes's claims are discussed: Pettit’s discussion in terms of indexicals, and Alexandra’s in terms of sense and reference.) This phenomenon is, Hobbes thinks, pervasive in our use of moral and political language. Indeed he says his analysis applies to all “names of such things as affect us, that is, which please, and displease us” (Leviathan 4.24), which seems a very broad category indeed. This inconstancy of signification has considerable potential to cause confusion and conflict. Given those practical consequences, it is of some importance for Hobbes to find a solution to this problem. The paper examines several possible Hobbesian solutions to the problem. There is, however, reason to think that these suggested solutions cannot completely solve the problem. The paper concludes, then, by arguing that double and inconstant signification would always be a danger, even in a properly constituted Hobbesian commonwealth. (shrink)

Version 4.4 October, 1994 Introduction When explaining human behavior, anthropologists frequently distinguish the things that people do of their own free will from the things they do because they have to. In much of anthropology, and most American archaeology, this is the difference between style and function. Functional behaviors are the things people are constrained to do; stylistic behaviors are the things people do when unconstrained. Where necessity stops and free choice begins is, of course, a classic problem of social (...) science theory, but wherever the boundary is placed, it is generally implied that the domains thus divided are not of equal importance (Bettinger 1991:49-50). Few straddle this fence: Materialists emphasize function and downplay style; structuralists and postmodernists do the opposite. Recent attempts to apply neo- Darwinian concepts to the archaeological record predictably side with materialist tradition, repeating the premise that it is most important to explain functional behavior; stylistic behavior is interesting only for localizing social units in time and space.

Chapter 4, “Foucault’s Theatre of War”, presents the thematic of constant war as a logical framework for grasping the genealogical use of history which has the potential to bring about its own wreckage with telling political underpinnings. The auto-destructive structure of Foucault’s hystorical critique locates a point of impossibility for its own operations which I approach from Lacan’s account of the Real as the impossible qua discursive formalization. Drawing on clinical perspectives, I explain how Foucault’s genealogical staging of “repeated scenes (...) of violence” brings into focus the binary structure of the modern discursive arena as an ongoing struggle between the psychoanalytic ‘forces’ of hysterical desire (the Hysteric) and perverse drive (the University). The structural impasse of the Real in Foucault’s hystorical critique leads to a comment on the topological structure of the Möbius band in a discursive context. I conclude Chapter 4 by arguing that the framework of war impels Foucauldian critique toward a moment outside of discourse and thus forces him to pass to another one. (shrink)

Kant speaks repeatedly about the relations between ends or aims and scientific research, but the topic has mostly been ignored. What is the role of ends, especially (though not exclusively) practical ones, in his views on science? I will show that while Kant leaves ample space for recognizing a function of ends both in the definition and the pursuit of inquiry, and in the further practical application of scientific cognition, he does not claim that science is simply an instrument for (...) achieving practical ends. I explain his complex conception, pointing out that Kant argues (1) that the sciences require ends for their very definition, (2) that ends come in fundamentally different kinds, (3) that the relation between science and ends requires the rational determination and hierarchization of all our ends, with “wisdom” as the highest, and (4) that this determination and hierarchization – which ought to be done by metaphysics – has itself to be carried out in a “scientific way”. I show further that (5) Kant gives sui generis weight to the epistemic aims and standards of science and to the autonomy of science from our practical lives. This places his position between separatism and anti-separatism with regard to the relation between science and our ends or values. (shrink)

Background Intensive care nurses repeatedly witness suffering, dying, grief, and conflict. In contemporary intensive care, protocols and monitoring routines can compress nursing work into execution and vigilance, limiting opportunities to exercise moral agency and creating ethically fraught “witnessing” positions. Research objectives To explore how intensive care nurses experience vicarious trauma, and how moral agency, ethical tensions, and organizational conditions shape its accumulation and repair. Research design A qualitative study using face-to-face semi-structured interviews and reflexive thematic analysis. Participants and research context (...) Fifteen registered nurses from a general intensive care unit in eastern China, purposively sampled for maximum variation in gender, professional title, experience, and recent high-impact exposures. Ethical considerations Ethical approval was obtained from the Ethics Committee of The First Affiliated Hospital of Zhejiang Chinese Medical University (approval number: 2025-KLS-184-02). Written informed consent was obtained; confidentiality and a distress protocol were applied. Findings Four themes were generated: (1) occupational boundary permeation and resonance, including identity mirroring, emotional absorption, and moral tension; (2) a spectrum of adaptation, where defensive distancing functioned as a strategy of moral survival under repeated exposure; (3) fractures in professional meaning and points of rupture, including constrained voice and experiences of powerless witnessing; and (4) meaning reconstruction in the cracks, reflecting moral repair through process-oriented care, renewed boundaries, and re-grounding in dignity-preserving practice. Conclusions Vicarious trauma in intensive care nursing is not only an individual psychological burden but an ethical and organizational phenomenon shaped by constrained moral agency and ethically contested trajectories of care. Interventions should move beyond individualized resilience and strengthen ethical infrastructures that legitimize nursing voice, support reflective processing, and enable ethically defensible practice in high-acuity settings.

Inquiries into organisational scandals repeatedly attribute wrongdoing to the normalisation of deviance. From this perspective, the cause of harm lies not in the actions of any individual but rather in the institutionalised practices of organisations or sectors. Although an important corrective to dramatic tales of bad apples, the normalisation thesis underplays the role of management in the emergence of deviance. Drawing on literatures exploring ideas of amoral (Carroll in Bus Horiz 30(2):7–15, 1987) or ethically neutral leadership (Treviño et al. in (...) Calif Manag Rev 42(4):128–142, 2000) we seek to bring management back into the explanation of organisational wrongdoing. Amoral theorists point to management’s ethical silence, but they also describe the way in which that silence is sustained by a series of organisational characteristics. We build on this work in arguing that it is management’s deliberate focus on bottom line performance, the diffusion of responsibility and high levels of organisational identification that explain the emergence of wrongdoing. We apply these ideas to the case of the UK’s Stafford hospital which hit the headlines in 2009 when it was reported that poor standards of care had led to a mortality rate markedly above that expected for a hospital of its type.

In hisMeditations, Marcus Aurelius repeatedly presents a disjunction between two conceptions of the natural world. Either the universe is ruled by providence or there are atoms. At 4.3, we find perhaps its most succinct statement: ἀνανεωσάμενος τὸ διεζευγμένον τό⋅ ἤτοι πρόνοια ἢ ἄτομοι (recall the disjunction: either providence or atoms). The formulation of the disjunction differs; at 7.32, being composed of atoms is contrasted with a stronger sort of unity (ἕνωσις) that may survive death. In 10.6 and 11.18 Marcus simply (...) offers φύσις (nature, construed in the Stoic manner as providentialist and causally efficacious) in opposition. On the surface, the contrast between the theory of atomism and the acceptance of providence seems to not warrant the term ‘disjunction’; it seems possible to accept both atomism and a causally determined providential universe. Yet, it is agreed on all sides, in the recent literature, that the relevant contrast for Marcus is not between the atomist and the non-atomist views of the constitution of the natural world as such but between two entailments that follow from the atomist Epicurean and the non-atomist Stoic advocacy of these positions. The contrast is between the providential ordering of the Stoic universe and the chaotic chance-ridden Epicurean model. (shrink)

continent. 1.4 (2011): 286—310. This mad play of writing —Stéphane Mallarmé Somewhere in between mathematics and theory, light and dark, physicality and projection, oscillates the poetry of Alessandro De Francesco. The texts hold no periods or commas, not even a capital letter for reference. Each piece stands as an individual construction, and yet the poetry flows in and out of the frame. Images resurface from one poem to the next, haunting the reader with reincarnations of an object lost in the (...) grass or a representation of a pear in a Dutch still life, embedded in cycles of cinematic close ups and multiple dimensions. As a whole, De Francesco’s oeuvre suggests, to use the title of one of his works, a redefinition —linguistic, epistemological, personal. The poem The End (un’agenda) (The End (an agenda)) opens with a quote by literary theorist Maurice Blanchot, which may be translated as follows: Speaking is not seeing. Speaking frees thought from this optical imperative that in the Western tradition, for thousands of years, has subjugated out approach to things, and induced us to think under the guaranty of light or under the threat of its absence.[1] In writing, De Francesco seeks to redefine our approach to things. His poems, like Blanchot’s writings, speak to both illuminate and to obscure. The reader hangs in an absence of reality within language that necessitates an attempt at interpretation, yet renders such a search ultimately futile. De Francesco draws the anonymous images that appear in this poem from the city of Paris, his current home. The fragmented narrative depicts an inner doubt of realness, calling for a confirmation of a physical existence beyond verbalization and cogitation. Cyclical references to film throw into question the reliability of the reality he creates. The light, sometimes red and safe, other times absent and murky, cannot necessarily be trusted as a guaranteed means of illumination. Blanchot’s distinction between language and visualization, and the relationship of each to reality, though linked specifically to The End (un’agenda), can be a lens through which to read any of the three works that follow. assente obliqua (absent oblique) is composed of descriptions of six still life paintings, ranging from Dutch masterpieces of the seventeenth century to 1960s minimalism. The actual images of the paintings are absent, and the text is the sole source and object of a virtual reality created around the artwork. “Absent oblique” refers to the light source placed outside of the frame, which both informs and distracts viewing of the scene. Although mere description can be unreliable and unsatisfying in its necessary limitation, the representational act of description is shown as more than just a human want. It is a need, a means by which to grapple with an unsure reality. As the illustrations progress, they descend into abstraction and chaos. The precariously placed plate triggers the movement: the bottle bursts and the objects collapse into the movement of a tracking film camera. corpo estraneo in moto ascensionale (foreign body in ascending motion) is prose poetry in action. Its objective tone of description is skewed by the subjectivity of the narrative as horrific images are relayed in fragmented but matter-of-fact manner. A “foreign body” is both a mass of cancerous cells, and a corporeal description, and the poem takes the reader on a journey back and forth between the two, destination unclear. Beyond a questioning of the real, corpo estraneo in moto ascensionale is an examination of the possible. De Francesco’s poetry becomes a camera obscura through which to observe the constant flux of light and dark that blurs our reality. His work is colored by the idea of apo koinou, a Greek term meaning “from the common” that involves a construction of two clauses with a shared word or phrase. Through such melting of meaning, De Francesco creates a fluid ambiguity that is nonetheless grounded in bodily concepts. In assente obliqua, the reader is confronted with a description of a still life that rapidly transforms into a more chilling scene: the membrane of the mushroom in the basket emerges behind the white cloth a body could hide itself that asks for help In the realm of pure description, there is a mushroom that peeks out from behind a white cloth in a basket. Behind the white cloth, too, there could be a body, hiding, asking for help. Such an elision elicits disorienting mistrust in temporality, but also expands the planar possibilities of syntactical meaning. A white cloth is not merely a construct in still life painting, but veil that both shields and reveals potential mysteries. It is a proposed alternative to a traditional Western binary of subjectivity and objectivity. The apo koinou construction is rare in modern English, having slipped out of use after its resurgence in Old English poetry. De Francesco reintroduces this blur of object and subject relations into a modern light. He draws inspiration from a device used by Gruppo 63 founder and avant-garde poet Antonio Porta tended toward repetition of phrases in third person perspective. In Italian, it is perfectly grammatically correct to omit the subject, including only a verb conjugation. Gender, even humanity unknown, the subject dissolves into the action, thus giving to the poetry the power to change the reader’s perception of who or what is actually acting. To further push the relative boundaries of experience, De Francesco expands his written poetry into what he calls “reading environments.” In these sound experiments, De Francesco’s voice reading his poetry is manipulated by real time digital voice processing. The written is transformed to the spoken, and then injected with currents of electric sound. “At each activation of word in the darkness,” (from The End (un’agenda) ) language is permutated into a nonphysical yet all-encompassing being. In these projects, realized all over Europe, De Francesco continues his examination of the word’s potency beyond the page and into an “n-dimensional space,” where the lines between nature and affect are intertwined. To publish excerpts of De Francesco’s oeuvre is to show screen shots of full-length film, to read pull quotes from a philosophy treatise. In these poems, there are questions, not to be answered, but to be questioned again. The words will oscillate in and out of the square construction found in his poems, out of the borders of the page, out of the rectangle of the laptop screen. NOTES (1) Blanchot, Maurice.

Adams and Aizawa, in a series of recent and forthcoming papers,, ) seek to refute, or perhaps merely to terminally embarrass, the friends of the extended mind. One such paper begins with the following illustration: "Question: Why did the pencil think that 2+2=4? Clark's Answer: Because it was coupled to the mathematician" Adams and Aizawa ms p.1 "That" the authors continue "about sums up what is wrong with Clark's extended mind hypothesis". The example of the pencil, they suggest, is just (...) an especially egregious version of a fallacy said to pervade the literature on the extended mind. This fallacy, which they usefully dub the " coupling-constitution fallacy ", is attributed, in varying degrees and manners, to Van Gelder and Port, Clark and Chalmers, Haugeland, Dennett, Clark, Gibbs, and Wilson. The fallacy, of course, is to move from the causal coupling of some object or process to some cognitive agent, to the conclusion that the object or process is part of the cognitive agent, or part of the agent's cognitive processing ms p.2). Proponents of the extended mind and related theses, Adams and Aizawa repeatedly assert, are prone to this fallacy in part because they either ignore or fail to properly appreciate the importance of " the mark of the cognitive" viz the importance of an account of "what makes something a cognitive agent". The positive part of Adams and Aizawa's critique then emerges as a combination of the assertion that this "mark of the cognitive" involves the idea that "cognition is constituted by certain sorts of causal process that involve non-derived contents" and that these processes look to be characterized by psychological laws that turn out to apply to many internal goings-on but not currently to any processes that take place in non-biological tools and artifacts. In what follows, I shall try to show why these arguments display nothing so much as mutual failures of communication: crossed wires concealing a couple of real, important, but much more subterranean, disagreements. In particular, I try to show why the negative considerations advanced by Adams and Aizawa fail to successfully undermine the argument for the extended mind, and why their more radical positive story, unless supplemented by implausible additional claims, fails to cast doubt on the claim that minds like ours can extend into the world.

It is often thought that judgments about what we ought to do are limited by judgments about what we can do, or that “ought implies can.” We conducted eight experiments to test the link between a range of moral requirements and abilities in ordinary moral evaluations. Moral obligations were repeatedly attributed in tandem with inability, regardless of the type (Experiments 1–3), temporal duration (Experiment 5), or scope (Experiment 6) of inability. This pattern was consistently observed using a variety of moral (...) vocabulary to probe moral judgments and was insensitive to different levels of seriousness for the consequences of inaction (Experiment 4). Judgments about moral obligation were no different for individuals who can or cannot perform physical actions, and these judgments differed from evaluations of a non-moral obligation (Experiment 7). Together these results demonstrate that commonsense morality rejects the “ought implies can” principle for moral requirements, and that judgments about moral obligation are made independently of considerations about ability. By contrast, judgments of blame were highly sensitive to considerations about ability (Experiment 8), which suggests that commonsense morality might accept a “blame implies can” principle. (shrink)

In a famous passage from the Philosophical Investigations, Wittgenstein describes a pupil who has been learning to write out various sequences of numbers in response to orders such as “+1” and “+2”. He has shown himself competent for numbers up to 1000, but when we have him continue the “+2” sequence beyond 1000, he writes the numerals 1004, 1008, 1012. As Wittgenstein describes the case: We say to him, “Look what you’re doing!” — He doesn’t understand us. We say “You (...) should have added two; look how you began the series!” — He answers: “Yes! Isn’t it right? I thought that’s how I should [sollen] do it. — Or suppose he were to say, pointing to the series, “But I went on in the same way!”1The passage continues:— It would now be no use to us to say “But don’t you see…?” — and repeat for him the old explanations and examples. — In such a case, we might perhaps say: this person naturally understands our order, once given our explanations, as we would understand the order “Add 2 up to 1000, 4 up to 2000, 6 up to 3000, and so on.”.

I argue that scientific realism, insofar as it is only committed to those scientific posits of which we have causal knowledge, is immune to Kyle Stanford’s argument from unconceived alternatives. This causal strategy is shown not to repeat the shortcomings of previous realist responses to Stanford’s argument. Furthermore, I show that the notion of causal knowledge underlying it can be made sufficiently precise by means of conceptual tools recently introduced into the debate on scientific realism. Finally, I apply this (...) strategy to the case of Jean Perrin’s experimental work on the atomic hypothesis, disputing Stanford’s claim that the problem of unconceived alternatives invalidates a realist interpretation of this historical episode. 1 Stanford’s Argument from Unconceived Alternatives2 Previous Attempts to Undermine the Problem of Unconceived Alternatives2.1 The plausibility of unconceived alternatives2.2 The distinctness of unconceived alternatives2.3 The induction from past to present3 Causal Knowledge as a Criterion for the Realist3.1 How Chakravartty’s proposal differs from earlier causal strategies3.2 Causal realism and the detection/auxiliary distinction4 Causal Realism, Unconceived Alternatives, and the Atomic Hypothesis4.1 Perrin and the philosophers: some initial observations4.2 Roush and Stanford on Perrin4.3 From Brownian motion to the reality of atoms4.4 What we know about atoms5 Conclusion.

Our epistemic access to the past is infamously patchy: historical information degrades and disappears and bygone eras are often beyond the reach of repeatable experiments. However, historical scientists have been remarkably successful at uncovering and explaining the past. I argue that part of this success is explained by the exploitation of dependencies between historical events, entities, and processes. For instance, if sauropod dinosaurs were hot blooded, they must have been gluttons; the high-energy demands of endothermy restrict sauropod grazing strategies. Understanding (...) such dependencies extends our reach into the past in spite of incomplete data. In addition, this serves as a counterexample to two accounts of method in the historical sciences. By one, historical science proceeds by identifying ‘smoking guns’: traces that discriminate between live hypotheses. By the other, historical hypotheses are supported by consilience: the convergence of independent lines of evidence. However, testing for ‘coherency’ between past hypotheses also plays a critical role in historical confirmation. Just as historical scientists exploit dependencies between past entities and present entities to infer what the past was like, they also exploit dependencies between past entities themselves. I do not suggest that archetypical historical science proceeds in this manner. Rather, the lesson I draw is that historical methodology cannot be characterized as archetypically relying on one method or another. Historical science is at base opportunistic, and is resistant to unitary analyses. 1 Introduction2 Snowballs and Explosions: The Basic Idea3 Were Sauropods Endothermic?4 Dependent Entities and Interdependent Explanations5 Smoking Guns and Consilience.

Background: Moral reasoning is a vital skill in the nursing profession. Teaching moral reasoning to students is necessary toward promoting nursing ethics. Objectives: The aim of this study was to compare the effectiveness of problem-based learning and lecture-based methods in ethics education in improving (1) moral decision-making, (2) moral reasoning, (3) moral development, and (4) practical reasoning among nursing students. Research design: This is a repeated measurement quasi-experimental study. Participants and research context: The participants were nursing students in a University (...) of Medical Sciences in west of Iran who were randomly assigned to the lecture-based (n = 33) or the problem-based learning (n = 33) groups. The subjects were provided nursing ethics education in four 2-h sessions. The educational content was similar, but the training methods were different. The subjects completed the Nursing Dilemma Test before, immediately after, and 1 month after the training. The data were analyzed and compared using the SPSS-16 software. Ethical considerations: The program was explained to the students, all of whom signed an informed consent form at the baseline. Findings: The two groups were similar in personal characteristics (p > 0.05). A significant improvement was observed in the mean scores on moral development in the problem-based learning compared with the lecture-based group (p < 0.05). Although the mean scores on moral reasoning improved in both the problem-based learning and the lecture-based groups immediately after the training and 1 month later, the change was significant only in the problem-based learning group (p < 0.05). The mean scores on moral decision-making, practical considerations, and familiarity with dilemmas were relatively similar for the two groups. Conclusion: The use of the problem-based learning method in ethics education enhances moral development among nursing students. However, further studies are needed to determine whether such method improves moral decision-making, moral reasoning, practical considerations, and familiarity with the ethical issues among nursing students.

The primary aim of this essay is to explain the central elements of Locke's theory of knowledge. A secondary aim arises from the official definition of knowledge introduced in the opening lines of book IV. Though Locke's repeated statements of the definition are consistent with the initial formulation, the consensus view among commentators is that that official definition is in tension with other book IV doctrines. My broader interpretation involves an effort to render the various doctrines consistent with the official (...) definition. The order of discussion: Section 1 explicates the definition of knowledge. Section 2 explains two main divisions of knowledge – namely, its three degrees, and the four sorts of knowable truths. In Section 3, I consider whether Locke understands knowable truths on a model of analyticity. Section 4 addresses potential problems about the objectivity of knowledge, given Locke's account. Section 5 focuses on external world knowledge – Locke calls this "sensitive knowledge" and it poses special difficulties for the official definition of knowledge. (shrink)

(Ak 10:74).[1] During the so-called ‘silent decade’ of the 1770s, when Kant was working on the Critique of Pure Reason, he promised repeatedly not only that he would soon finish that work but also that he would soon publish a “metaphysics of morals” (Ak 10:97, 132, 144).[2] Yet it was not until four years after the first Critique that Kant finally wrote a work on ethics, and even then he merely laid the ground for a metaphysics of morals by identifying (...) and establishing the supreme principle on which a system of duties would be based (G 4:392). Three years later, in the Critique of Practical Reason Kant once again dealt entirely with foundational questions in moral philosophy. Kantian ethics is primarily known, especially among English-speaking philosophers, through these two ethical works of the 1780s, neither of which contains anything like a ‘metaphysics of morals’.

The fourteenth-century thinker Thomas Bradwardine is well known in both the history of science and the history of theology. The first of the Merton Calculators (mathematical physicists) and passionate defender of the Augustinian doctrine of salvation through grace alone, he was briefly archbishop of Canterbury before succumbing to the Black Death in 1349. This new edition of his Insolubilia, made from all thirteen known manuscripts, shows that he was also a logician of the first rank. The edition is accompanied by (...) a full English translation. In the treatise, Bradwardine considers and rejects the theories of his contemporaries about the logical puzzles known as 'insolubles,' and sets out his own solution at length and in detail. In a substantial introduction, Stephen Read describes Bradwardine's analysis, compares it with other more recent theories, and places it in its historical context. The text is accompanied by three appendices, the first of which is an extra chapter found in two manuscripts (and partly in a third) that appears to contain further thoughts by Bradwardine himself. The second contains an extract from Ralph Strode's Insolubilia, composed in the 1360s, repeating and enlarging on Bradwardine's text; and the third consists of an anonymous text that applies Bradwardine's solution to a succession of different insolubles"--P.

This volume contains C. D. Broad's Cambridge lectures on Ethics. Broad gave a course of lectures on the subject, intended primarily for Part I of the Moral Sciences Tripos, every academic year from 1933 - 34 up to and in cluding 1952 - 53 (except that he did not lecture on Ethics in 1935 - 36). The course however was frequently revised, and the present version is es sentially that which he gave in 1952 - 53. Broad always wrote out (...) his lectures fully beforehand, and the manuscript on Ethics, although full of revisions, is in a reasonably good state. But his handwriting is small and close and in places difficult to decipher. I therefore fear that some words may have been misread. There was an additional complication. In the summer of 1953 Broad revised and enlarged two sections of the course, namely the section on "Moore's theory" and that on "Naturalistic theories" (both sections occur in Chapter 4). The revised version of the section on Moore is undoubtedly superior to the earlier version, and I have therefore included it. But in my opinion this is not true of the new version of the section on naturalistic theories: although more comprehensive than the earlier version, it is not only repetitive in itself, but also repeats, sometimes almost verbatim, passages which occur elsewhere in the lectures. In brief, the new version is not fully integrated with the rest of the course. (shrink)

On a postcard to Franz Overbeck from January 4, 1888, Nietzsche makes some illuminating remarks with respect to the three treatises in his book On the Genealogy of Morality.2 Nietzsche says that, ‘for the sake of clarity, it was necessary artificially to isolate the different roots of that complex structure that is called morality. Each of these three treatises expresses a single primum mobile; a fourth and fifth are missing, as is even the most essential (‘the herd instinct’) – for (...) the time being, the latter had to be ignored, as too comprehensive, and the same holds for the ultimate summation of all those different elements and thus a final account of morality.’ Nietzsche also points out that each treatise makes a contribution to the genesis of Christianity and rejects an explanation of Christianity in terms of only one psychological category. The topics of the treatises are ‘good’ and ‘evil’ (first treatise), the ‘bad conscience’ (second), and the ‘ascetic ideal’ (third). The postcard suggests that Nietzsche discusses these topics separately because a joint treatment is too complicated, but that in reality, these ideas are inextricably intertwined, both with each other and with others that Nietzsche omits. Therefore, the three treatises should be regarded as parts of a unified theory and critique of morality. Nietzsche’s remarks on that postcard are important because in the Genealogy itself, he makes little effort to show the unity among the treatises. We shall return to this postcard repeatedly.3 The first treatise has attracted most scholarly attention, but much less work has been done on the second treatise, ‘ “Debts”, “Bad Conscience”, and Related Matters’. This is unfortunate, since it seems that, in Nietzsche’s own view, the central notion of the second treatise, namely, the bad conscience as a feeling of guilt, is a key element of Christian morality. Therefore, understanding Nietzsche’s treatment of this notion is essential to understanding his views on Christianity and the impact of the Christian heritage on non-religious moral philosophy..

Did Leibniz exploit infinitesimals and infinities à la rigueur or only as shorthand for quantified propositions that refer to ordinary Archimedean magnitudes? Hidé Ishiguro defends the latter position, which she reformulates in terms of Russellian logical fictions. Ishiguro does not explain how to reconcile this interpretation with Leibniz’s repeated assertions that infinitesimals violate the Archimedean property (i.e., Euclid’s Elements, V.4). We present textual evidence from Leibniz, as well as historical evidence from the early decades of the calculus, to undermine Ishiguro’s (...) interpretation. Leibniz frequently writes that his infinitesimals are useful fictions, and we agree, but we show that it is best not to understand them as logical fictions; instead, they are better understood as pure fictions.

In lieu of an abstract, here is a brief excerpt of the content:20. HUME ON REASON1 One of the main concerns of Hume's Treatise of 2 Human Nature (T) is the investigation of the role that reason plays in belief and action. On the standard interpretation, Hume is taken to argue that neither our beliefs nor our actions are determined by reason; Books I and III are thus seen as sharing a common theme: the denigration of reason's role in human (...) affairs. Arguing for this view, Kemp Smith claims that "Hume's principle of the subordination of reason to the passions runs through his whole philosophy ", not merely through Books II and III. This interpretation of Hume's enterprise presupposes that the faculty of reason whose role in action is discussed in Book III is the same faculty which has been shown not to determine belief in Book I. In this paper I argue that a univocal reading of 'reason' and related terms like 'reasoning' throughout the Treatise has the consequence that there are major internal inconsistencies in Hume's philosophy, cannot account for some important sections of the work, and leads to misinterpretation of the nature of his overall argument. In its place I develop an interpretation which avoids these difficulties and emphasizes the radical nature of Hume's naturalism. The Argument of the Treatise Let me begin by reviewing the salient features of the main argument of the Treatise. In Book I, Hume is concerned to show that our most fundamental beliefs — e.g., about the continued and distinct existence of object, about what we are not presently observing, and in the existence of the self — are not acquired by reason, but instead by the imagination, influenced by custom and habit. In a typical passage, he argues: Reason can never shew us the connexion of one object with another, tho' aided by experience, and the observation of their constant conjunction in all past instances. When the mind, 21. therefore, passes from the idea or impression of one object to the idea or belief of another, it is not determin'd by reason... (T92)4 In Book III, and in Book II, Part III, Section III (Of the influencing motives of the will), Hume is concerned to show that reason alone can never produce any action, or give rise to volition (T414), and the same faculty is as incapable of preventing volition, or of disputing the preference with any passion or emotion (T414-415). Hume uses this result in Book III, Part I, Section I, to show that the rules of morality...are not conclusions of our reason (T457). Proponents of the univocal reading of 'reason' would hold that the Treatise thus constitutes a continuous attack on reason, showing that it causes neither our most fundamental beliefs nor our actions and moral judgments. But if this reading were correct, Hume would fail to avail himself of an obvious and persuasive argument for the conclusion he reaches in Books II and III, and in the latter books he would contradict the results of Book I. Conflict between Book I and Books II and III If Hume did have the same faculty in mind throughout the Treatise, a strong argument to show that reason does not cause action would be available to him in Books II and III, utilizing the results he has established in Book I. The principal way in which reason would be thought to influence action is by informing us of facts about efficient means to achieve our ends and about the possible effects of actions — facts about causal relations. Since the conclusion of Book I is that judgments about causal relations do not result from reason, it follows that even if such beliefs did cause action, it would still not be the case that reason caused action. But Hume not only does not make such an argument in Books II and III, he denies one of its premises — the claim that beliefs about causal relations do not result from reason — which was the main conclusion of Book I. In the 22. later books he asserts repeatedly that reason can cause beliefs about causal relations. For example, in Book III, he says:...reason, in a strict and philosophical... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 62.3 (2001) 381-399 [Access article in PDF] Permissive Natural Law and Property: Gratian to Kant Brian Tierney In his Doctrine of Right Kant set out to formulate a theory of property that would be based on purely rational argumentation, that would abstract "from all spatial and temporal conditions," and that would be applicable to any person, "merely because and insofar as he is (...) free and has practical reason." But from the time when the work first appeared Kant scholars have found many difficulties in the teaching that he presented. Many of them relate to the idea of permissive natural law that Kant introduced at a key point to his argument.In a previous, complementary article I discussed in detail various apparent aporias that arose in Kant's treatment of this concept and suggested that we might understand his problems better by setting them in a broader historical context than those considered in standard works like those of Reinhard Brandt and Wolfgang Kersting. 1 This is the theme that I want to explore further in the present paper.To sum up briefly some of the difficulties in the Doctrine of Right: A central problem for Kant was to explain how rightful possession of individual property could emerge from a hypothetical state of nature where everything was common to all, where everyone had a right to everything. His argument was grounded on a concept of freedom understood as "a pure rational concept." Kant maintained that every person had an innate right to freedom and from this he deduced a universal law of Right: "[S]o act externally that the free use of your choice can coexist with the freedom of everyone." 2 But the person who first seized for himself what had been common to all evidently did encroach on the freedom of others (their freedom to use the property that had been taken). [End Page 381]To address this problem Kant formulated a "postulate of practical reason" concerning property. Citing the Roman law doctrine of res nullius he argued that external things could in principle be acquired. 3 Then he restated the postulate as a permissive law that obliged others to respect the claim of a first occupant. "This postulate can be called a permissive law (lex permissiva) of practical reason which gives us an authorization... to put all others under an obligation, which they would not otherwise have...." 4 But to put others under an obligation is to encroach on their freedom, which would be a violation of the universal law of Right. For Kant, laws that could be discerned by reason alone without promulgation by a legislator, were understood to be natural laws. 5 The universal law of Right and the permissive law of practical reason were both laws of this kind. It seems therefore that natural law contradicted itself. It prohibited and permitted an action at the same time.Other difficulties arose as the argument proceeded. Kant repeatedly asserted that rightful possession must depend on consent expressed in "a collective general (common) and powerful will," "a will that is united originally and a priori"; 6 but he acknowledged that such a general will would not exist in a state of nature before the institution of civil society and that an act of original acquisition would necessarily proceed from a unilateral will. "But the will that a thing is to be mine... can be only unilateral." 7 And yet Kant also wrote, "By my unilateral choice I cannot bind another to refrain from using a thing, an obligation he would not otherwise have." 8 Kant never did explain how a permissive law, allowing a person to act unilaterally, could impose an obligation on others.In my earlier discussion of Kant's work I indicated that it might be fruitful to approach these difficulties by investigating some previous ways of using the language of permissive natural law, especially as it related to the origin of property rights. There is indeed a whole earlier tradition of thought to be considered. An investigation of this material... (shrink)

The burgeoning literature on jus post bellum has repeatedly reaffirmed three positions that strike me as deeply implausible: that in the aftermath of wars, compensation should be a priority; that we should likewise prioritize punishing political leaders and war criminals even in the absence of legitimate multilateral institutions; and that when states justifiably launch armed humanitarian interventions, they become responsible for reconstructing the states into which they have intervened – the so called “Pottery Barn” dictum, “You break it, you own (...) it.” Against these common positions, this chapter argues that compensation should be subordinate to reconstruction, with resources going where they are most needed and can do the most good, rather than to the most aggrieved. Just punishment, meanwhile, presupposes just multilateral institutions – the victor cannot be trusted to mete out punishment fairly. And just interveners, who have already taken on such a heavy burden, are entitled to expect the international community to contribute to reconstruction after they have made the first and vital steps. After presenting each of these objections in greater depth, the chapter proceeds to draw some tentative inferences from the threads running through each, and suggest that they illustrate a distinctive flaw in the way in which jus post bellum is addressed by many just war theorists, who not only see the war as the grounds of post bellum duties, but also take it to specify their content: Specifically, they take the rights violations with which wars are imbued to be the basis for post-war action, but take the content of post-war duties to be focused on rectifying those rights violations, rather than the more forward-looking goal of establishing a lasting peace. This backward-looking orientation unduly confines these theorists to making attributions of fault, to a limited palette of normative concepts, and to a focus on the belligerents rather than the international community as a whole. Undoubtedly warfare creates a distinctive normative relationship between belligerent states (though we must question how much of this devolves to the citizens of those states). War does generate grounds for post-war duties – but there are other grounds for those duties too, moreover the grounds should not determine the content. It of course matters that the citizens of two states harmed one another in violation of their rights. But when the war is done, peacebuilding should be the priority, not raking over the wrongs of both sides. Sections 2–4 present the objections, Section 5 offers the tentative analysis and proposes a shift in focus toward an ethics of peacebuilding, and Section 6 concludes. (shrink)

Background The idea that individuals are responsible for their health has been the focus of debate in the theoretical literature and in its concrete application to healthcare policy in many countries. Controversies persist regarding the form, substance and fairness of allocating health responsibility to the individual, particularly in universal, need-based healthcare systems. Objective To examine how personal health responsibility has been framed and rationalised in Norwegian key policy documents on priority setting. Methods Documents issued or published by the Ministry of (...) Health and Care Services between 1987 and 2018 were thematically analysed (n=14). We developed a predefined conceptual framework that guided the analysis. The framework included: (1) the subject and object of responsibility, (2) the level of conceptual abstraction, (3) temporality, (4) normative justificatory arguments and (5) objections to the application of personal health responsibility. Results As an additional criterion, personal health responsibility has been interpreted as relevant if: (A) the patient’s harmful behaviour is repeated after receiving treatment (retrospectively), and if (B) the success of the treatment is conditional on the patient’s behavioural change (prospectively). When discussed as a retrospective criterion, considerations of reciprocal fairness have been dominant. When discussed as a prospective criterion, the expected benefit of treatment justified its relevance. Conclusion Personal health responsibility appears to challenge core values of equality, inclusion and solidarity in the Norwegian context and has been repeatedly rejected as a necessary criterion for priority setting. However, the responsibility criterion seems to have some relevance in particular priority setting decisions. (shrink)

Since Machery et al. _Cognition_ 92, B1-B12 ( 2004 ) attacked Kripke’s refutation of classical descriptivism, their experiment has been repeated several times, in its original version or in some revised ones, by theorists with contrasting intents. Some repeated the experiment for confirming its results, others for proving them unreliable. One striking characteristic of those surveys is that they mostly replicated the data collected in Machery et al.’s _Cognition_ 92, B1-B12, 2004 experiment: less than 60% of Westerners showed preference for (...) the causal-historical response. We side with the critics of Machery et al.’s experiment. In this paper, we present the results of a survey that tests some hypotheses for explaining that percentage of Westerners’ preferences without taking it as evidence that more than 40% of Westerners have descriptivist intuitions on semantic reference. The aim of our paper is not merely to question the reliability of Machery et al.’s experiment. In sections 4 and 5 we assess the impact of our survey on the current debate in experimental semantics. We provide a novel account of the nature of the epistemic ambiguity that affects experiments in theory of reference and explain the consequences that our account of the epistemic ambiguity has for subsequent works trying to avoid ambiguities.

In August 2021, Froese et al. published survey data collected from 2,543 respondents on their subjective experiences living under imposed social distancing measures during COVID-19 (1). The questionnaire was issued to respondents in the UK, Japan, and Mexico. By combining the authors’ expertise in phenomenological philosophy, phenomenological psychopathology, and enactive cognitive science, the questions were carefully phrased to prompt reports that would be useful to phenomenological investigation and theorizing (2–4). These questions reflected the various author’s research interests (e.g., technology, grief, (...) time). Between April 7th and July 31st, 2021, a second questionnaire with the same question set was issued to respondents of the original who had agreed to do a follow-up. This was intended to capture subjective reports of life under social distancing measures a year after the initial survey. By this time–depending on their country of residence and health status–respondents had potentially lived with repeated and prolonged lockdowns and a variety of other restrictions on their social lives. When taken together, Survey I and Survey II provide a cross-cultural and longitudinal dataset that allows for analysis of longer-term impacts of imposed social distancing measures on people’s experiences. For researchers working in diverse disciplines, this dataset offers a rich resource that reflects people’s reactions to the imposition of different social restrictions in different countries and over different time periods.

The distinction between ‘comprehensive’ and ‘political’ liberalisms, explored in the previous chapter, has become central to contemporary political theory. My aim in this chapter is to examine various ‘comprehensive’ liberalisms, with particular care to identifying in what sense they are comprehensive. As I have argued elsewhere (Gaus, 2003: chap. 7), the distinction between political and comprehensive liberalisms is elusive. Rawls repeatedly describes as ‘comprehensive’ ‘philosophical’, ‘moral’ and ‘religious’ ‘doctrines’ (1996: xxv, 4, 36, 38, 160) or ‘beliefs’ (1996: 63). Indeed, so (...) often does Rawls characterize comprehensiveness in terms of moral, religious and philosophical doctrines or beliefs that a reader may be tempted to conclude that doctrine C is comprehensive if and only if it is a moral, religious or philosophical doctrine or belief. But though it is tempting to understand ‘comprehensive conceptions’ in this way, it would be wrong. Rawls is clear that ‘the distinction between the political conception and other moral conceptions is a matter of scope; that is, the range of subjects, to which a conception applies and the content a wider range requires’ (1996: 13). Comprehensive and general doctrines cover a wide range of topics, values and ideals applicable to various areas of life. Even given the terms of Rawls’s own analyses, rather than conceiving of comprehensive liberalisms as all relying on a fully comprehensive doctrine, it is better to conceive of them in terms of a spectrum of theories, from those that rely on something like a fully comprehensive view to those that rely on, say, only a general theory of the right. In this chapter I shall focus on the following versions of comprehensive liberalism. (shrink)

Samuel Golubchuk was unwittingly at the center of a medical controversy with important ethical ramifications. Mr. Golubchuk, an 84-year-old patient whose precise neurological level of function was open to debate, was being artificially ventilated and fed by a gastrostomy tube prior to his death. According to all reports he was neither brain dead nor in a vegetative state. The physicians directly responsible for his care had requested that they be allowed to remove the patient from life support against the wishes (...) of the patient's family. Concurrently the Manitoba College of Physicians and Surgeons released a statement which states that the final decision to withdraw life support lies with the physician. In our opinion the statement is ethically problematic for a number of reasons. 1. It is an affront to the guiding principles of Western medical ethics: patient autonomy and human freedom. 2. The position of Samuel Golubchuk's physicians and the new statement lack cultural sensitivity towards other traditions. 3. In modern society there exists an erosion of a basic attitude towards the value of life. 4. The ability of physicians to predict life expectancy in terminally ill patients has been shown repeatedly to be quite limited. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 43.1 (2005) 55-81 [Access article in PDF] Self-Knowledge in Descartes and Malebranche Lawrence Nolan John Whipple 1. Introduction Descartes's notorious claim that mind is better known than body has been the target of repeated criticisms, but none appears more challenging than that of his intellectual heir Nicolas Malebranche.1 Whereas other critics—especially twentieth-century philosophers eager to use Descartes as their whipping boy—have often been (...) uncharitable, Malebranche accepts many of the fundamental Cartesian doctrines, including mind-body dualism. But he argues that Descartes's position on knowledge of the mind is internally inconsistent. Malebranche agrees with Descartes that the existence of the mind is better known than that of body, but he vehemently denies that the nature of the mind is better known. This denial is based on his view that we lack a clear idea of the mind.2 [End Page 55]Malebranche's polemic has attracted much attention in recent scholarship.3 The growing consensus among commentators is that Malebranche develops a devastating internal critique of Descartes's theory of the mind. For example, Nicholas Jolley writes: "In his case for his negative thesis [concerning knowledge of the mind] Malebranche mounted a powerful, even annihilating, critique of Descartes. This critique embodies the remarkable insight that there is a serious muddle at the heart of Descartes's whole theory of knowledge."4 In a book-length defense of Malebranche's critique, Tad Schmaltz also emphasizes its internal character: "the interpretation here of Malebranche's theory presents it as fundamentally Cartesian, and thereby serves to reinforce his own view that he has provided an authoritative interpretation of the account of mind in the writings of Descartes and other Cartesians."5 Schmaltz also asserts: "Malebranche took his negative thesis concerning our knowledge of the soul to involve not so much a rejection of Cartesianism as an internal correction of it."6We think such remarks misstate the case. Indeed, we argue in this paper that Malebranche's polemic fails as an internal critique of Descartes's theory of the mind. Although we do not here aspire to defend Descartes's strong thesis—that mind is better known than body—we do think he can consistently maintain that we have a clear and distinct idea of the mind, and thus that our knowledge of the mind's nature is at least on a par with our knowledge of corporeal nature.7 While Malebranche's rhetoric would encourage us to think that the debate between him and his predecessor is being fought on common or neutral ground, the fact is that Malebranche often appeals to assumptions and aspects of his own theory of "Vision in God" that Descartes would reject. Once more, he interprets Descartes's theory of knowledge in ways that are misguided and sometimes even uncharitable. If Malebranche's critique succeeds at all, it succeeds only against a straw man—Malebranche's Descartes and not the historical figure.Ours is not the first effort to defend Descartes against this particular attack. When Malebranche first published his critique in Book Three of his first great work, The Search After Truth (1674),8 Descartes had been dead for over two decades, [End Page 56] but he was ably defended by the famous Cartesian Antoine Arnauld in On True and False Ideas (1683). In the ensuing debate Arnauld was clearly the superior dialectician, but while winning several tactical points, he appears not to fully appreciate the crux of Malebranche's argument, or at least that is the view of Jolley and Schmaltz.9 We have a somewhat higher opinion of Arnauld's side of the debate. Granted, some of his defenses are facile and can be easily dismissed; others however are quite compelling when properly developed. In at least one instance, we attempt to provide that development. At the same time we think it is a mistake to treat Arnauld as Descartes's surrogate or as if he had issued the final salvo from the camp of the orthodox Cartesians. Arnauld was a... (shrink)

There are two principles that lend Brouwer's mathematics the extra power beyond arithmetic. Both are presented in Brouwer's writings with little or no argument. One, the principle of bar induction, will not concern us here. The other, the continuity principle for numbers, occurs for the first time in print in [4]. It is formulated and immediately applied to show that the set of numerical choice sequences is not enumerable. In fact, the idea of the continuity property can be dated fairly (...) precisely, it is to be found in the margin of Brouwer's notes for his course on Pointset Theory of 1915/16. The course was repeated in 1916/17 and he must have inserted his first formulation of the continuity principle in the fall of 1916 as new material right at the beginning of the course.In modern language, the principle readswhere α and β range over choice sequences of natural numbers, m and x over natural numbers, and stands for ⟨α, α, …, α⟩, the initial segment of α of length m.An immediate consequence of WC-N is that all full functions are continuous, and, as a corollary, that the continuum is unsplittable [28]. Note that WC-N is incompatible with Church's thesis, [22], section 4.6.After Brouwer asserted WC-N, Troelstra was the first to ask in print for a conceptual motivation, but he remained an exception; most authors followed Brouwer by simply asserting it, cf. [18].Let us note first that in one particular case the principle is obvious indeed, namely in the case of the lawless sequences. The notion of lawless sequence surfaced fairly late in the history of intuitionism. Kreisel introduced it in [17] for metamathematical purposes. There is a letter from Brouwer to Heyting in which the phenomenon also occurs [7]. This is an important and interesting fact since it is the only time that Brouwer made use of a possibility expressly stipulated in, e.g., [5], see below. (shrink)

ObjectiveTo present (1) the ethical concepts related to the debate on resuscitation of extremely premature infants (EPIs) as they are described in the ethical literature; and (2) the ethical arguments based on these concepts.DesignWe conducted a systematic review of the ethical literature. We selected articles based on the following predefined inclusion/exclusion criteria: (1) English language articles (2) presenting fully elaborated ethical arguments (3) on resuscitation (4) of EPIs, that is, infants born before 28 weeks of gestation.AnalysisAfter repeated reading of articles, (...) we developed individual summaries, conceptual schemes and an overall conceptual scheme. Ethical arguments and concepts were identified and analysed.ResultsForty articles were included out of 4709 screened. Personhood, best interest, autonomy and justice were concepts grounding the various arguments. Regarding these concepts, included authors agreed that the best interest principle should guide resuscitation decisions, whereas justice seemed the least important concept. The arguments addressed two questions: Should we resuscitate EPIs? Who should decide? Included authors agreed that not all EPIs should be resuscitated but disagreed on what criteria should ground this decision. Overall, included authors agreed that both parents and physicians should contribute to the decision.ConclusionsThe included publications suggest that while the best interest is the main concept guiding resuscitation decisions, justice is the least important. The included authors also agree that both parents and physicians should be actively involved in resuscitation decisions for EPIs. However, our results suggest that parents’ decision should be over-ridden when in contrast with the EPI’s best interest. (shrink)

One way to do socially relevant investigations of science is through conceptual analysis of scientific terms used in special-interest science (SIS). SIS is science having welfare-related consequences and funded by special interests, e.g., tobacco companies, in order to establish predetermined conclusions. For instance, because the chemical industry seeks deregulation of toxic emissions and avoiding costly cleanups, it funds SIS that supports the concept of "hormesis" (according to which low doses of toxins/carcinogens have beneficial effects). Analyzing the hormesis concept of its (...) main defender, chemical-industry-funded Edward Calabrese, the paper shows Calabrese and others fail to distinguish three different hormesis concepts, H, HG, and HD. H requires toxin-induced, short-term beneficial effects for only one biological endpoint, while HG requires toxin-induced, net-beneficial effects for all endpoints/responses/subjects/ages/conditions. HD requires using the risk-assessment/regulatory default rule that all low-dose toxic exposures are net-beneficial, thus allowable. Clarifying these concepts, the paper argues for five main claims. (1) Claims positing H are trivially true but irrelevant to regulations. (2) Claims positing HG are relevant to regulation but scientifically false. (3) Claims positing HD are relevant to regulation but ethically/scientifically questionable. (4) Although no hormesis concept (H, HG, or HD) has both scientific validity and regulatory relevance, Calabrese and others obscure this fact through repeated equivocation, begging the question, and data-tri mm ing. Consequently (5) their errors provide some undeserved rhetorical plausibility for deregulating low-dose toxins. (shrink)

Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and gauge theories. Indeed, repeated attempts to collapse these disanalogies have made us acutely aware that there are fairly general obstacles to doing so. Nonetheless, there is a special case space-time dimensions) in which gravity is often claimed to be identical to a gauge theory. I subject this claim to philosophical scrutiny in this article. In particular, I analyse how the standard disanalogies can (...) be overcome in dimensions, and consider whether really licenses the interpretation of gravity as a gauge theory. Our conceptual analysis reveals more subtle disanalogies between gravity and gauge, and connects these to interpretive issues in classical and quantum gravity. 1 Introduction1.1 Motivation1.2 Prospectus2 Disanalogies3 Three-dimensional gravity and gauge3.1 gravity3.2 Chern–Simons3.2.1 Cartan geometry3.2.2 Overcoming obst-gauge via Cartan connections3.3 Disanalogies collapsed4 Two More Disanalogies4.1 What about the symmetries?4.2 The phase spaces of the two theories5 Summary and Conclusion.

Absent evidence reasoning is common in many sciences, including astronomy, archeology, biology and medicine. An often-repeated epistemological motto is that “the absence of evidence is not evidence of absence.” Analysis of absent evidence reasoning usually takes place in a deductive or frequentist hypothesis-testing framework. Instead, I develop a Bayesian analysis of (...) this motto and prove that, under plausible assumptions about the nature of evidence, the absence of evidence is evidence of absence. (shrink)
