In this paper I critically examine the implications of the uncodifiability thesis for principlism as a pluralistic and non-absolute generalist ethical theory. In this regard, I begin with a brief overview of W.D. Ross’s ethical theory and his focus on general but defeasible prima facie principles before turning to 2) the revival of principlism in contemporary bioethics through the influential work of Tom Beauchamp and James Childress; 3) the widespread adoption of specification as a response to the indeterminacy of abstract (...) general principles and the limitations of balancing and deductive approaches; 4) the challenges raised to fully specified principlism by the uncodifiability thesis and 5) finally offer a defense of the uncodifiability thesis against various critiques that have been raised.

Contemporary epistemology has been moving away from classical foundationalism—the thesis that our empirical knowledge is grounded in perceptual beliefs we know with certainty. McGrew reexamines classical foundationalism and offers a compelling reconstruction and defense of empirical knowledge grounded in perceptual certainty. He articulates and defends a new version of foundationalism and demonstrates how it meets all the standard criticisms. The book offers substantial rebuttals of the arguments of Kuhn and Rorty and demonstrates the value of the classical analytic approach to (...) philosophy. 'Foundations' will interest philosophers of science, language, and the mind. (shrink)

My fundamental thesis is that Rachels dismisses the traditional Western account of the morality of killing without offering a viable replacement. In this regard, I will argue that the substitute account he offers is deficient in at least eight regards: (1) he fails to justify the foundational principle of utilitarianism, (2) he exposes preference utilitarianism to the same criticisms he lodges against classical utilitarianism, (3) he neglects to explain how precisely one performs the maximization procedure which preference utilitarianism requires, (4) (...) his account of the sanctity of life is subject to the very criticism he levels against the traditional position, (5) he cannot justify the exceptions he makes to his interpretation of the sanctity of life, (6) his account could easily be used to justify murder, (7) his embrace of autonomy as an ethical principle undermines his preference utilitarianism, and (8) he cannot maintain the moral identification of acts of killing and letting die.

Previous research has suggested that bodily signals from internal organs are associated with diverse cortical and subcortical processes involved in sensory-motor functions, beyond homeostatic reflexes. For instance, a recent study demonstrated that the preparation and execution of voluntary actions, as well as its underlying neural activity, are coupled with the breathing cycle. In the current study, we investigated whether such breathing-action coupling is limited to voluntary motor action or whether it is also present for mental actions not involving any overt (...) bodily movement. To answer this question, we recorded electroencephalography (EEG), electromyography (EMG), and respiratory signals while participants were conducting a voluntary action paradigm including self-initiated motor execution (ME), motor imagery (MI), and visual imagery (VI) tasks. We observed that the voluntary initiation of ME, MI, and VI are similarly coupled with the respiration phase. In addition, EEG analysis revealed the existence of readiness potential (RP) waveforms in all three tasks (i.e., ME, MI, VI), as well as a coupling between the RP amplitude and the respiratory phase. Our findings show that the voluntary initiation of both imagined and overt action is coupled with respiration, and further suggest that the breathing system is involved in preparatory processes of voluntary action by contributing to the temporal decision of when to initiate the action plan, regardless of whether this culminates in overt movements. -/- .

Secondary education around the world has been significantly disrupted by covid-19. Students have been forced into new ways of independent learning, often using remote technologies, but without the social nuances and direct teacher interactions of a normal classroom environment. Using data from the School Attitudes Survey—which surveys students regarding the perceived level of difficulty, anxiety level, self-efficacy, enjoyability, subject relevance, and opportunities for creativity with regards to each of their school subjects—this study examines students' responses to this disruption from two (...) very different schools with two very different experiences of the pandemic. This paper reports on the composite attitudinal profiles of students in the senior secondary levels at each school. The findings challenged our expectation that the increased difficulty and anxiety caused by the disruption would reduce perceived opportunities for creativity. Indeed, our analyses showed that the students at both schools demonstrated generally positive attitudes toward their learning and strongly associated opportunities for creativity with other attitudinal constructs including enjoyability, subject relevance, and self-efficacy. These complex associations made by the students appear to have buffered the impacts of the disruption, and they may even have supported creative resilience. (shrink)

Abstract:In this article I stage an encounter between Adriana Cavarero's account of uniqueness and Hortense Spillers's account of the flesh. Doing so is valuable for two reasons: First, it forces Cavarero's thought to consider not only the exclusion of women from the Western tradition, but also the anti-Blackness foundational to this tradition. This both expands and contorts Cavarero's thought, affirming her key claims while also altering them in the process. Second, reading Cavarero and Spillers together allows me to explore the (...) way forms of life that evade representation can be known. Both uniqueness and the flesh are evasive of representation; by reading them together—supplementing Cavarero's consideration of the embodied character of uniqueness with Spillers's distinction between body and flesh—I develop an account of apprehension that emphasizes touch as a way of knowing apart from representation. Apprehension takes seriously the ambivalence in Spillers's account of the flesh, whereby it is both revealed through violence as well as through practices of care, which, as Saidiya Hartman has made clear, are often in a proximate relation in the ongoing legacies of transatlantic slavery.

The doctrine of the Incarnation, that Jesus Christ was both truly God and truly human, is the foundation and cornerstone of traditional Christian theism. And yet this traditional teaching appears to verge on incoherence. How can one person be both God, having all the perfections of divinity, and human, having all the limitations of humanity? This is the fundamental philosophical problem of the Incarnation. Perhaps a solution is found in an analysis of what the traditional teaching meant by person, divinity, (...) and humanity, or in understanding how divinity and humanity were united in a single person. This Element presents that traditional teaching, then returns to the incoherence problem to showcase various solutions offered to it. (shrink)

Solon's extraordinary claim, that we should call "no one happy who is still living", presents a fascinating and distinctive argument about happiness and the length of a human life. The issues Solon raises are important, and even if we think his pessimistic conclusion is an exaggeration we can still appreciate his central concern how conceptions of happiness and the length of a human life are connected. The purpose of this paper is to explore a few of these problems, in particular (...) the reason why Aristotle's reply to Solon in the Nicomachean Ethics is somewhat ambiguous. We find Aristotle addressing Solon's claim at the outset of Eth. Nic. A 10, troubled in one sense by its conclusion, yet struck by its partial truth. On the one hand, he thinks that requires a "complete life" or at the very least, a sufficient and "complete span of time", both of which are compatible with Solon's advice that we should postpone calling someone happy until a later point in life. But on the other hand Aristotle defines in such a way that raises the question whether he needs to accept Solon's claim in any form. In particular, if happiness is defined in terms of excellent activity as Aristotle repeatedly claims, why should we wait until a person dies to call him or her happy? Why shouldn't excellent actions, at the very time they are performed, count someone as happy? The puzzle, in short, is the fact that Aristotle defines happiness in terms of activities that are complete without developing over time, and yet also claims that happiness requires a "complete lifetime".

The de‐repression of transposable elements (TEs) in mammalian genomes is thought to contribute to genome instability, inflammation, and ageing, yet is viewed as a cell‐autonomous event. In contrast to mammalian cells, prokaryotes constantly exchange genetic material through TEs, crossing both cell and species barriers, contributing to rapid microbial evolution and diversity in complex communities such as the mammalian gut. Here, it is proposed that TEs released from prokaryotes in the microbiome or from pathogenic infections regularly cross the kingdom barrier to (...) the somatic cells of their eukaryotic hosts. It is proposed this horizontal transfer of TEs from microbe to host is a stochastic, ongoing catalyst of genome destabilization, resulting in structural and epigenetic variations, and activation of well‐evolved host defense mechanisms contributing to inflammation, senescence, and biological ageing. It is proposed that innate immunity pathways defend against the horizontal acquisition of microbial TEs, and that activation of this pathway during horizontal transposon transfer promotes chronic inflammation during ageing. Finally, it is suggested that horizontal acquisition of prokaryotic TEs into mammalian genomes has been masked and subsequently under‐reported due to flaws in current sequencing pipelines, and new strategies to uncover these events are proposed.

Moral education requires interdisciplinary engagement across philosophy, psychology, and education. Positive psychologists regularly acknowledge the breadth and depth of wisdom regarding the cultivation of virtues present in philosophical and religious texts and consult such writings when creating constructs, but they are less prone to integrate scientific findings with historical texts as inquiry proceeds. Thus, we provide a comparative analysis of the advice given in Lorenzo Scupoli’s The Spiritual Combat, from traditional Christian moral wisdom literature and the research findings from positive (...) psychology on the cultivation of the virtue of patience. Points of convergence relate to the utility of engaging activities that include cognitive reappraisal, habit formation through daily practice, activating positive motivation, prayer, mantra/transcendental meditation, and cultivating elevation through meditation on moral exemplars. Areas of divergence include the advisability of suppression, the role of motivation, and necessity of spiritual intervention, which suggest areas for future inquiry in moral education. (shrink)

Kleist viewed anew as a major contributor to the tradition of post-Kantian thought.

At any given time, a subject has a multiplicity of conscious experiences. A subject might simultaneously have visual experiences of a red book and a green tree, auditory experiences of birds singing, bodily sensations of a faint hunger and a sharp pain in the shoulder, the emotional experience of a certain melancholy, while having a stream of conscious thoughts about the nature of reality. These experiences are distinct from each other: a subject could experience the red book without the singing (...) birds, and could experience the singing birds without the red book. But at the same time, the experiences seem to be tied together in a deep way. They seem to be unified, by being aspects of a single encompassing state of consciousness. (shrink)

New insights into the microbiome, epigenetics, and cognition are radically challenging our very idea of what it means to be 'human', while an explosion of neo-materialist thinking in the humanities has fostered a renewed appreciation of the formative powers of a dynamic material environment.

Neurovascular coupling (NVC), the transient regional hyperemia following the evoked neuronal responses, is the basis of blood oxygenation level-dependent techniques and is generally adopted across physiological conditions, including the intrinsic resting state. However, the possibility of neurovascular dissociations across physiological alterations is indicated in the literature. To examine the NVC stability across sleep–wake states, we used electroencephalography (EEG) as the index of neural activity and functional magnetic resonance imaging (fMRI) as the measure of cerebrovascular response. Eight healthy adults were recruited (...) for simultaneous EEG-fMRI recordings in nocturnal sleep. We compared the cross-modality (EEG vs. fMRI) consistency of functional indices (spectral amplitude and functional connectivity) among five states of wakefulness and sleep (state effect). We also segregated the brain into three main partitions (anterior, middle and posterior) for spatial assessments (regional effect). Significant state effects were found on δ, α and fMRI indices and regional effects on the α and fMRI indices. However, the cross-state EEG changes in spectral amplitude and functional connectivity did not consistently match the changes in the fMRI indices across sleep–wake states. In spectral amplitude, the δ band peaked at the N3 stage for all brain regions, while the fMRI fluctuation amplitude peaked at the N2 stage in the central and posterior regions. In regional connectivity, the inter-hemispheric connectivity of the δ band peaked at the N3 stage for all regions, but the bilateral fMRI connectivity showed the state changes in the anterior and central regions. The cross-modality inconsistencies across sleep–wake states provided preliminary evidence that the neurovascular relationship may not change in a linear consistency during NREM sleep. Thus, caution shall be exercised when applying the NVC presumption to investigating sleep/wake transitions, even among healthy young adults. (shrink)

Neural activity varies continually from moment to moment. Such temporal variability (TV) has been highlighted as a functionally specific brain property playing a fundamental role in cognition. We sought to investigate the mechanisms involved in TV changes between two basic behavioral states, namely having the eyes open (EO) or eyes closed (EC) in vivo in humans. To these ends we acquired BOLD fMRI, ASL, and [18F]-fluoro-deoxyglucose PET in a group of healthy participants (n = 15), along with BOLD fMRI and (...) [18F]-flumazenil PET in a separate group (n = 19). Focusing on an EO- vs EC-sensitive region in the occipital cortex (identified in an independent sample), we show that TV is constrained in the EO condition compared to EC. This reduction is correlated with an increase in energy consumption and with regional GABAA receptor density. This suggests that the modulation of TV by behavioral state involves an increase in overall neural activity that is related to an increased effect from GABAergic inhibition in addition to any excitatory changes. These findings contribute to our understanding of the mechanisms underlying activity variability in the human brain and its control. (shrink)

Objective Manic and depressive phases of bipolar disorder (BD) show opposite psychomotor symptoms. Neuronally, these may depend on altered relationships between sensorimotor network (SMN) and subcortical structures. The study aimed to investigate the functional relationships of SMN with substantia nigra (SN) and raphe nuclei (RN) via subcortical-cortical loops, and their alteration in bipolar mania and depression, as characterized by psychomotor excitation and inhibition. -/- Method In this resting-state functional magnetic resonance imaging (fMRI) study on healthy (n = 67) and BD (...) patients (n = 100), (1) functional connectivity (FC) between thalamus and SMN was calculated and correlated with FC from SN or RN to basal ganglia (BG)/thalamus in healthy; (2) using an a-priori-driven approach, thalamus-SMN FC, SN-BG/thalamus FC, and RN-BG/thalamus FC were compared between healthy and BD, focusing on manic (n = 34) and inhibited depressed (n = 21) patients. -/- Results (1) In healthy, the thalamus-SMN FC showed a quadratic correlation with SN-BG/thalamus FC and a linear negative correlation with RN-BG/thalamus FC. Accordingly, the SN-related FC appears to enable the thalamus-SMN coupling, while the RN-related FC affects it favoring anti-correlation. (2) In BD, mania showed an increase in thalamus-SMN FC toward positive values (ie, thalamus-SMN abnormal coupling) paralleled by reduction of RN-BG/thalamus FC. By contrast, inhibited depression showed a decrease in thalamus-SMN FC toward around-zero values (ie, thalamus-SMN disconnection) paralleled by reduction of SN-BG/thalamus FC (and RN-BG/thalamus FC). The results were replicated in independent HC and BD datasets. -/- Conclusions These findings suggest an abnormal relationship of SMN with neurotransmitters-related areas via subcortical-cortical loops in mania and inhibited depression, finally resulting in psychomotor alterations.

The neurotransmitters GABA and glutamate have been suggested to play a role in Major Depressive Disorder (MDD) through an imbalance between cortical inhibition and excitation. This effect has been highlighted in higher brain areas, such as the prefrontal cortex, but has also been posited in basic sensory cortices. Based on this, magnetic resonance spectroscopy (MRS) was used to investigate potential changes to GABA+ and glutamate+glutamine (Glx) concentrations within the occipital cortex in MDD patients (n = 25) and healthy controls (n (...) = 25). No difference in occipital GABA+ or Glx concentrations, nor in the GABA+/Glx ratio, was found between groups. An analysis of an extended MDD patient and unmatched control dataset (n = 90) found no correlation between metabolite concentrations and depressive symptoms. These results were integrated with prior studies through metabolite-specific meta-analyses, revealing no difference in occipital GABA and Glx concentrations between patients and controls. An effect of publication year on GABA group differences was found, suggesting that previously reported results may have been artifacts of measurement accuracy. Taken together, our results suggest that, contrary to some prior reports, MRS measurements of occipital GABA and Glx do not differ between MDD patients and controls. (shrink)

In Max Scheler’s powerful critique of modernity, he claimed that moderns suffer more in the midst of technological advancement, their values are set by an “ethos of industrialization,” and they have no unified vision of who they are.

In pointing beyond modernism, Scheler called for establishing personal, collective, and environmental harmony.

This book holds classical liberalism responsible for an American concept of beauty that centers upon women, wilderness, and machines. For each of the three beauty components, a cultural entrepreneur supremely sensitive to liberalism’s survival agenda is introduced. P.T. Barnum’s exhibition of Jenny Lind is a masterful combination of female elegance and female potency in the subsistence realm. John Muir’s Yosemite Valley is surely exquisite, but only after a rigorous liberal education prepares for its experience. And Harley Earl’s 1955 Chevrolet Bel (...) Air is a dreamy expressionist sculpture, but with a practical 265 cubic inch V-8 underneath. Not that American beauty has been uniformly pragmatic. The 1950s are reconsidered for having temporarily facilitated a relaxation of the liberal survival priorities, and the creations of painter Jackson Pollock and jazz virtuoso Ornette Coleman are evaluated for their resistance to the pressures of pragmatism. The author concludes with a provocative speculation regarding a future liberal habitat where Emerson’s admonition to attach stars to wagons is rescinded. (shrink)

In this article, I critically engage Adriana Cavarero’s account of uniqueness via an analysis of her work on narrativity and violence. I suggest there is an ambivalence in Cavarero’s account of uniqueness: Cavarero argues both that uniqueness is susceptible to destruction, and that it cannot finally be annihilated. To make this clear I use Cavarero’s account to read a narrative offered by Miklós Nyiszli, of a woman who survived an Auschwitz gas chamber. I contrast this to Cavarero’s reading of Eurydice (...) and Orpheus, arguing that the ambivalence in Cavarero’s account can be resolved by thinking an excess proper to uniqueness. (shrink)

Relative essentialism is the novel metaphysical theory that there can be multiple objects occupying the same space at the same time each with its own de re modal truths. Relative essentialism is motivated by Davidson’s semantics and his denial that nature itself is divided into a privileged domain of objects. Relative essentialism was first presented by Samuel C. Wheeler. I argue that Wheeler’s approach to the Davidsonian program needs to be elaborated in terms of various types of preconceptual intentional relations. (...) This elaboration is already largely implicit in Davidson’s own later work and in Wheeler’s relaunching of Davidsonian metaphysics. More specifically, I argue that relative essentialism is ultimately founded not on predication narrowly construed but on intentionality broadly construed. Following Wheeler’s suggestion, comparisons are made between relative essentialism and work within the phenomenological tradition. (shrink)

In this paper we defend the doxastic conception of delusions against the metacognitive account developed by Greg Currie and collaborators. According to the metacognitive model, delusions are imaginings that are misidentified by their subjects as beliefs: the Capgras patient, for instance, does not believe that his wife has been replaced by a robot, instead, he merely imagines that she has, and mistakes this imagining for a belief. We argue that the metacognitive account is untenable, and that the traditional conception of (...) delusions as beliefs should be retained. (shrink)

In this article I further Adriana Cavarero and Nidesh Lawtoo’s discussion of “mimetic inclination” to consider the way a person can be known in their uniqueness. Cavarero says that we receive a sense of the uniqueness of another by relating their narrative. I suggest that this also reveals a sense of the uniqueness of the one narrating, and that this can be understood as a practice of care. This narration is, as a consequence, distinct from representation (which itself is distinct (...) from mimesis) and is better described as apprehension. By drawing on Toni Morrison’s Beloved and Christina Sharpe’s In the Wake: On Blackness and Being, I detail a primary form of care connected to apprehension that is engendered by what Sharpe calls “the weather of antiblackness”. Morrison both details this form of care in Beloved and practises it herself in her storytelling. This expands feminist analyses of vulnerability, providing critical resources for rethinking existence apart from its colonial and patriarchal articulation. (shrink)

We discuss three varieties of affective dynamics. In each case, we suggest how these affective dynamics should be operationalized and measured in daily life using time-intensive methods, like ecological momentary assessment or ambulatory assessment, and recommend time-sensitive analyses that take into account not only the variability but also the temporal dependency of reports. Studies that explore how these affective dynamics are associated with psychological disorders and symptoms are reviewed, and we emphasize that these affective processes are within a nexus of (...) other components of emotion regulation.

Background Neuroimaging and lesion studies suggested that the dorsolateral prefrontal and posterior parietal cortices mediate visual metacognitive awareness. The causal evidence provided by non-invasive brain stimulation, however, is inconsistent. -/- Objective/hypothesis Here we revisit a major figure discrimination experiment adding a new Kanizsa figure task trying to resolve whether bilateral continuous theta-burst transcranial magnetic stimulation (cTBS) over these regions affects perceptual metacognition. Specifically, we tested whether subjective visibility ratings and/or metacognitive efficiency are lower when cTBS is applied to these two (...) regions in comparison to an active control region. -/- Methods A within-subjects design including three sessions spaced by one-week intervals was implemented. In each session, every participant was administered bilateral cTBS to either prefrontal, control or parietal cortices. Two concurrent tasks were performed, a real and an illusory figure task, stabilising objective performance with use of an adaptive staircase procedure. -/- Results When performing the replicated task, cTBS was found insufficient to disrupt neither visibility ratings nor metacognitive efficiency. However, with use of Kanizsa style illusory figures, cTBS over the dorsolateral prefrontal, but not over the posterior parietal cortex, was observed to significantly diminish metacognitive efficiency. -/- Conclusion(s) Real and illusory figure tasks demonstrated different cTBS effects. A possible explanation is the involvement of the prefrontal cortex in the creation of expectations, which is necessary for efficient metacognition. Failure to replicate previous findings for the real figure task, however, cannot be said to support, conclusively, the notion that these brain regions have a causal role in metacognitive awareness. This inconsistent finding may result from certain limitations of our study, thereby suggesting the need for yet further investigation. (shrink)

Two long-standing arguments in cognitive science invoke the assumption that holistic inference is computationally infeasible. The first is Fodor’s skeptical argument toward computational modeling of ordinary inductive reasoning. The second advocates modular computational mechanisms of the kind posited by Cosmides, Tooby and Sperber. Based on advances in machine learning related to Bayes nets, as well as investigations into the structure of scientific and ordinary information, I maintain neither argument establishes its architectural conclusion. Similar considerations also undermine Fodor’s decades-long diagnosis of (...) artificial intelligence research as confounded by an inability to circumscribe the amount of information relevant to inferential processes. This diagnosis is particularly inapposite with respect to Bayes nets, since one of their strengths as machine learning systems has been their capacity to reason probabilistically about large data sets whose size overwhelms the capacities of individual human reasoners. A general moral follows from these criticisms: Insights into artificial and human cognitive systems are likely to be cultivated by focusing greater attention on the structure and density of connections among items of information that are available to them.

ABSTRACT:Drawing upon the collective action model of institutional change, I reconceptualize moral imagination as both a social process and a cognitive one. I argue that moral outcomes are not produced by individual actors alone; rather, they emerge from collective action processes that are influenced by political conditions and involve behaviors that include issue framing and resource mobilization. I also contend that individual moral imagination involves the integration of moral sensitivity with consideration of collective action dynamics. I illustrate my arguments with (...) a case study of the Chad-Cameroon oil project. The paper suggests new directions in teaching and research on moral imagination. (shrink)
