Despite her emphasis on politics, Hannah Arendt’s account of the existential grounds of action in The Human Condition culminates in a discussion of Jesus of Nazareth that emphasizes the significance of forgiveness for grasping the radicality of human freedom. This essay investigates Jesus’s role in Arendt’s thought by excavating and explicating the premises that undergird her account of Jesus’s political significance. It argues that Arendt’s innovative approach to politics is complemented by a comparably innovative conception of human agency and shows (...) how Arendt’s defense of the autonomy of the political rests on a novel metaphysics of action—a ‘Kantian existentialism’—that underlies and explains her account of Jesus’s political significance.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hegel on Pseudo-Philosophy: Reading the Preface to the Phenomenology of Spirit by Andrew Alexander DavisPaul T. WilfordDAVIS, Andrew Alexander. Hegel on Pseudo-Philosophy: Reading the Preface to the Phenomenology of Spirit. London: Bloomsbury, 2023. ix + 214 pp. Cloth, $125In Hegel on Pseudo-Philosophy, Andrew Davis makes a convincing argument that just as the problem of how to distinguish sophistry from philosophy is a recurrent theme of Plato's dialogues, so (...) too is the problem of sophistry or "pseudo-philosophy" central to the preface to Hegel's Phenomenology of Spirit. Indeed, the problem of how to recognize and guard against pseudo-philosophy is the common theme linking the prefaces to the Phenomenology of Spirit, the Science of Logic, the Encyclopedia, and the Philosophy of Right, each of which endeavors "to reveal something about the essence of philosophy... by highlighting the ways pseudo-philosophy fails to do justice to philosophical content." Such an undertaking is especially important to Hegel's Phenomenology of Spirit, however, because the subject matter [End Page 543] of the work is nothing but the logos of the appearances of spirit. To arrive at knowledge of spirit requires attending to all the various ways in which spirit (or Geist) can appear, but, as Davis remarks, "like life, Geist may be thought as a source of appearances, but not as an appearance itself. It is always 'behind' what appears." As a result, the Phenomenology is an exercise in trying "to grasp what does not appear through appearances alone." Thus, just as the Phenomenology approaches the truth of spirit by considering spirit's partial, abstract, and one-sided modes of appearing, so too does the preface to the Phenomenology approach the truth of philosophy by investigating forms of pseudo-philosophy.As Hegel himself states, there are two principal tasks pursued in the preface: (1) to offer a preliminary sketch of what it would mean for "the cognition of absolute actuality to become perfectly lucid about its own nature;" and (2) to eliminate some "habitually accepted forms of thought" that prove obstacles to philosophic cognition. While most commentators take their bearings from the former, Davis's approach to the preface is unique (to my knowledge) in foregrounding the latter. Yet, as his book unfolds, it becomes clear that the latter is the route into the former. Indeed, one of the central lessons of the book is that, although the elimination of erroneous habits of thought may seem to be merely negative and therefore principally propaedeutic to the positive task of leading the reader toward "absolute knowing," the examination of error is an integral component of grasping the true. If the Phenomenology as a whole is a "highway of despair"—a comprehensive refutation of natural consciousness's pretensions to knowledge that is simultaneously a dialectical ascent to conceptually comprehending knowing (begreifende Wissen)—the preface initiates the reader into the via negativa that philosophic cognition must travel to attain self-knowledge.Davis's book is structured around seven forms of pseudo-philosophy, each of which is treated as a discrete, distinguishable problem in its own right and also as emblematic of the common failure to recognize that the form of philosophy is inseparable from the content of philosophy. As Davis argues, this failure lies at the root of the attempt (common to much of modern philosophy since Descartes) to establish a priori a universal method for thinking (what Leibniz called a mathesis universalis) that will secure certain and indubitable knowledge. But this effort proves self-undermining, always ultimately engendering the very skepticism it seeks to master. Through observing the aporiai generated by forms of pseudo-philosophy, we learn that "the method of philosophy is inseparable from the subject matter of philosophy. Method cannot be isolated and discussed on its own. Philosophy is thinking (form) about thinking (content)."Davis thus gradually discloses Hegel's positive answer to the question "what is philosophy?" through a series of determinate negations of philosophy's imitations. We learn that philosophy is the recollective, self-comprehending, self-moving thinking of thinking by attending to a set of tendencies that impede philosophy: "a tendency to explain rather than [End Page 544] present (chapter 1), a...

This paper offers an interpretation of and introduction to the philosophical anthropology of Roger Scruton through an examination of the aesthetic dimension of human rationality. We argue that attending to our aesthetic experience as individuated subjects capable of intersubjective communion offers a helpful corrective to the deracinated and disembodied view of human rationality prevalent in much of our contemporary ethical and scientific discourse. Through a consideration of how embodied rationality is at work in four different forms of art – painting, (...) music, dance, and architecture – our paper develops the rudiments of a more concrete philosophical anthropology, and on the basis of first principles advances a normative claim about the importance of art and beauty to human life.

At the heart of the drama of Hegel’s Phenomenology of Spirit is the realization of the concept of self-consciousness. The self-conscious agent strives to know herself through being known by another, and after repeated failures comes eventually to learn what is required for one to know and to be known. Hegel’s famous account of a life and death struggle for recognition between two self-conscious agents marks the beginning of a long development toward the realization of the multifaceted conditions for the (...) possibility of genuine intersubjective recognition and therewith for truly responsible agency. This development is concomitantly the actualization of the concept of spirit, for true agency requires the appearance of absolute spirit in a community of self-conscious individuals. This paper explores why forgiveness is so central to this process. According to Hegel’s argument, we only fully realize our nature as self-conscious beings when we acknowledge our need for forgiveness. (shrink)

Through a reexamination of Immanuel Kant and his philosophical legacy, this volume explores the philosophic presuppositions of the possibility of progress and our belief in reason's capacity not only to improve the material well-being of humanity but also to promote our true vocation as moral beings.

The authors investigated the ontological argument computationally. The premises and conclusion of the argument are represented in the syntax understood by the automated reasoning engine PROVER9. Using the logic of definite descriptions, the authors developed a valid representation of the argument that required three non-logical premises. PROVER9, however, discovered a simpler valid argument for God's existence from a single non-logical premise. Reducing the argument to one non-logical premise brings the investigation of the soundness of the argument into better focus. Also, (...) the simpler representation of the argument brings out clearly how the ontological argument constitutes an early example of a ?diagonal argument? and, moreover, one used to establish a positive conclusion rather than a paradox.

The cuticular surface of Drosophila is decorated by parallel arrays of polarized structures such as hairs and sensory bristles; for example, on the wing each cell produces a distally pointing hair. These patterns are termed [tissue polarity]. Several genes are known whose activity is essential for the development of normal tissue polarity. Mutations in these genes alter the orientation of the hair or bristle with respect to neighboring cells and the body as a whole. The phenotypes of mutations in these (...) genes allows them to be placed in three phenotypic groups. Based on their behavior in genetic mosaics, it has proved possible to determine that individual genes are required either for the generation of an intercellular polarity signal and/or the transduction of that signal to the cytoskeleton.

Though Frege was interested primarily in reducing mathematics to logic, he succeeded in reducing an important part of logic to mathematics by defining relations in terms of functions. By contrast, Whitehead & Russell reduced an important part of mathematics to logic by defining functions in terms of relations (using the definite description operator). We argue that there is a reason to prefer Whitehead & Russell's reduction of functions to relations over Frege's reduction of relations to functions. There is an interesting (...) system having a logic that can be properly characterized in relational but not in functional type theory. This shows that relational type theory is more general than functional type theory. The simplification offered by Church in his functional type theory is an over-simplification: one can't assimilate predication to functional application.<br>. (shrink)

In this paper, the authors show that there is a reading of St. Anselm's ontological argument in Proslogium II that is logically valid (the premises entail the conclusion). This reading takes Anselm's use of the definite description "that than which nothing greater can be conceived" seriously. Consider a first-order language and logic in which definite descriptions are genuine terms, and in which the quantified sentence "there is an x such that..." does not imply "x exists". Then, using an ordinary logic (...) of descriptions and a connected greater-than relation, God's existence logically follows from the claims: (a) there is a conceivable thing than which nothing greater is conceivable, and (b) if <em>x</em> doesn't exist, something greater than x can be conceived. To deny the conclusion, one must deny one of the premises. However, the argument involves no modal inferences and, interestingly, Descartes' ontological argument can be derived from it. (shrink)

The director of Courage International talks about the work of the apostolate in addressing homosexuality according to the mind and heart of the Church, which he calls “one of the most demanding aspects of education, formation, and pastoral care today.” But it is also an opportunity to attend to the often acute and persistent wounds of those who need healing within what Pope Francis calls the “field hospital” of the Church. The author points out that the work of Courage is (...) not first about homosexuality but about what it means to be human. It is an invitation to consider the question of the fulfillment of the human heart according to God’s gracious plan. National Catholic Bioethics Quarterly 15.2 : 221–230. (shrink)

Over recent years, the research community has been increasingly using preprint servers to share manuscripts that are not yet peer-reviewed. Even if it enables quick dissemination of research findings, this practice raises several challenges in publication ethics and integrity. In particular, preprints have become an important source of information for stakeholders interested in COVID19 research developments, including traditional media, social media, and policy makers. Despite caveats about their nature, many users can still confuse pre-prints with peer-reviewed manuscripts. If unconfirmed but (...) already widely shared first-draft results later prove wrong or misinterpreted, it can be very difficult to “unlearn” what we thought was true. Complexity further increases if unconfirmed findings have been used to inform guidelines. To help achieve a balance between early access to research findings and its negative consequences, we formulated five recommendations: (a) consensus should be sought on a term clearer than ‘pre-print’, such as ‘Unrefereed manuscript’, “Manuscript awaiting peer review” or ‘’Non-reviewed manuscript”; (b) Caveats about unrefereed manuscripts should be prominent on their first page, and each page should include a red watermark stating ‘Caution—Not Peer Reviewed’; (c) pre-print authors should certify that their manuscript will be submitted to a peer-review journal, and should regularly update the manuscript status; (d) high level consultations should be convened, to formulate clear principles and policies for the publication and dissemination of non-peer reviewed research results; (e) in the longer term, an international initiative to certify servers that comply with good practices could be envisaged.

Our computational metaphysics group describes its use of automated reasoning tools to study Leibniz’s theory of concepts. We start with a reconstruction of Leibniz’s theory within the theory of abstract objects (henceforth ‘object theory’). Leibniz’s theory of concepts, under this reconstruction, has a non-modal algebra of concepts, a concept-containment theory of truth, and a modal metaphysics of complete individual concepts. We show how the object-theoretic reconstruction of these components of Leibniz’s theory can be represented for investigation by means of automated (...) theorem provers and finite model builders. The fundamental theorem of Leibniz’s theory is derived using these tools. (shrink)

Web-based platforms play an increasingly important role in managing and sharing research data of all types and sizes. This article presents a case study of the data storage, sharing, and management platform Figshare. We argue that such platforms are displacing and reconfiguring the infrastructure of norms, technologies, and institutions that underlies traditional scholarly communication. Using a theoretical framework that combines infrastructure studies with platform studies, we show that Figshare leverages the platform logic of core and complementary components to re-integrate a (...) presently splintered scholarly infrastructure. By means of this logic, platforms may provide the path to bring data inside a scholarly communication system still optimized mainly for text publications. Yet the platform strategy also risks turning over critical scientific functions to private firms whose longevity, openness, and corporate goals remain uncertain. It may amplify the existing trend of splintering infrastructures, with attendant effects on equity of service. (shrink)

© 2016 Elsevier LtdJumping spiders are famous for their visually driven behaviors [1]. Here, however, we present behavioral and neurophysiological evidence that these animals also perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level. Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds by freezing—a common (...) anti-predatory behavior characteristic of an acoustic startle response. Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones —recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain. Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. Thus, these spiders appear able to detect airborne sound at distances in the acoustic far-field region, beyond the near-field range often thought to bound acoustic perception in arthropods that lack tympanic ears [2]. Furthermore, direct mechanical stimulation of hairs on the patella of the foreleg was sufficient to generate responses in neural units that also responded to airborne acoustic stimuli—evidence that these hairs likely play a role in the detection of acoustic cues. We suggest that these auditory responses enable the detection of predators and facilitate an acoustic startle response. Video. (shrink)

Diffusion theory explains in physical terms how materials move through a medium, e.g. water or a biological fluid. There are strong and widely acknowledged grounds for doubting the applicability of this theory in biology, although it continues to be accepted almost uncritically and taught as a basis of both biology and medicine. Our principal aim is to explore how this situation arose and has been allowed to continue seemingly unchallenged for more than 150 years. The main shortcomings of diffusion theory (...) will be briefly reviewed to show that the entrenchment of this theory in the corpus of biological knowledge needs to be explained, especially as there are equally valid historical grounds for presuming that bulk fluid movement powered by the energy of cell metabolism plays a prominent note in the transport of molecules in the living body. First, the theory's evolution, notably from its origins in connection with the mechanistic materialist philosophy of mid nineteenth century physiology, is discussed. Following this, the entrenchment of the theory in twentieth century biology is analyzed in relation to three situations: the mechanism of oxygen transport between air and mammalian tissues; the structure and function of cell membranes; and the nature of the intermediary metabolism, with its implicit presumptions about the intracellular organization and the movement of molecules within it. In our final section, we consider several historically based alternatives to diffusion theory, all of which have their precursors in nineteenth and twentieth century philosophy of science. (shrink)
