I think that to Lord Kelvin is attributed the saying that the scientific attitude to a thing, if you can't do anything else with it, is to measure it. This is the attitude I propose to adopt towards Time . The situation is to some extent analogous to the situation with regard to electricity . Science is unable to say what electricity is, and so it almost denies the word any entrance into a treatise on the subject. It replaces it (...) by the word charge , which is something that can be measured. It is important to avoid hypostatizing time into a thing-in-itself. Instead of trying to say what time is we try to find a way of measuring it. (shrink)

Recent results in kinematics, obtained by myself and those working with me, have convinced me that the philosophical status of physics, as it has come down to us from Renaissance days, requires reconsideration. The reason can be stated in a couple of sentences: it has been found possible to establish certain laws of physics—laws of motion, the law of gravitation, the laws known under the name of the Lorentz transformation, and some others—purely deductively, without specific assumptions, and without empirical appeals (...) save only to the empirical awareness of something we call “the passage of time.” Yet physicists have claimed ad nauseam that the ultimate sanction for “laws of nature” is observation and experiment, that this is what distinguishes physics from other branches of exact inquiry. The contrast in these two conceptions of natural law needs no emphasis. It is the purpose of this article to attempt to clarify this confused situation. (shrink)

Perception of music and speech is based on similar auditory skills, and it is often suggested that those with enhanced music perception skills may perceive and learn novel words more easily. The current study tested whether music perception abilities are associated with novel word learning in an ambiguous learning scenario. Using a cross-situational word learning (CSWL) task, nonmusician adults were exposed to word-object pairings between eight novel words and visual referents. Novel words were either non-minimal pairs differing in all sounds (...) or minimal pairs differing in their initial consonant or vowel. In order to be successful in this task, learners need to be able to correctly encode the phonological details of the novel words and have sufficient auditory working memory to remember the correct word-object pairings. Using the Mistuning Perception Test (MPT) and the Melodic Discrimination Test (MDT), we measured learners’ pitch perception and auditory working memory. We predicted that those with higher MPT and MDT values would perform better in the CSWL task and in particular for novel words with high phonological overlap (i.e., minimal pairs). We found that higher musical perception skills led to higher accuracy for non-minimal pairs and minimal pairs differing in their initial consonant. Interestingly, this was not the case for vowel minimal pairs. We discuss the results in relation to theories of second language word learning such as the Second Language Perception model (L2LP).

Studying the similarities and differences in socio-communicative behavior between chimpanzees and bonobos is critical to increasing our understanding of the evolution of human sociality and communication. Both species rely heavily on the use of vocalizations during communicative interactions, although the form and function of these signals may vary between the two ape species. For example, bonobo vocalizations seem to be structurally more complex than those produced by chimpanzees, and calls seem to be directed to individuals not in immediate physical proximity. (...) Both species, however, make use of communicative signals from different modalities concurrently, particularly vocalizations and manual gestures. However, this multimodal communication is more commonly observed in chimpanzees when compared to bonobos, who more frequently use vocalizations exclusively, without signals from additional modalities. In addition, there are a number of marked differences in social characteristics between the two species. Though both species exhibit fission–fusion behavior, chimpanzees do so more often, potentially as a result of their habitat profile and foraging strategies. Differences also exist in terms of dominance and aggression. Chimpanzees live in largely patriarchal societies with strong male–male bonds, whereas bonobos tend to be matriarchal with strong female–female bonds. These differences in communicative and social characteristics are thought to be linked to the ecology of the respective habitats of the two apes and their strategies for resource exploitation. In all likelihood, similarities in feeding ecology played a crucial role in selecting for the advanced cognitive abilities of both species—e.g., producing meaningful communicative signals, regulating competition and group cohesion, and making and utilizing tools to aid in foraging. Similarly, differences in their respective habitats may have led to selection for characteristics resulting in the behavioral differences observed today between the two species. Therefore, a clearer understanding of the similarities and differences between the two species most closely related to humans will provide valuable information into our own evolution by elucidating those characteristics shared among humans and our ape ancestors and those derived in the hominin lineage.

In this paper, we explore the ontological and theological ground of political institutions in order to then reflect upon the eschatological calling of society. The paper builds on Tillich's ontological insight that love does not simply transcend justice, but that it permeates and drives justice, that justice gives form to love's reunion of the separated. This relation between love and justice is at play in political institutions: these unite human beings under forms of justice that must be transformed ever anew (...) if they are not to lose touch with the dynamic power of love and freeze into increasingly unjust juridicalism. The modern history of Western civilisation bears witness to this ontological tension, and the phenomenon of globalisation is yet another instance of human society's mystical calling. Thus, love heads the dynamic movement that transforms political institutions ever anew. Yet society as a whole must become conscious of its ontology for humanity to truly reach its eschatological potential, and this will require both that theology recovers its ground and that political theory thinks theologically.

La hermenéutica de Gadamer se presenta como otro modo de pensar el ser en la experiencia de la comprensión del arte. De ahí, su expresión «el ser que puede ser comprendido es lenguaje ». El trabajo gira en torno a este enunciado como una actitud vital de la época contemporánea, más allá de la era de la fe y la razón. En ello, se funde la conciencia histórica efectual y circula el juego entre diálogo/traducción/interpretación como modelo de una estética del (...) lenguaje humano. Este acto de pensar con Gadamer encuentra la luminosidad de la verdad en la poesía como lenguaje primigenio del género humano. (shrink)

Plausibly, when we adopt a probabilistic standpoint any measure Cb of the degree to which evidence e confirms hypothesis h relative to background knowledge b should meet these five desiderata: Cb > 0 when P > P < 0 when P < P; Cb = 0 when P = P. Cb is some function of the values P and P assume on the at most sixteen truth-functional combinations of e and h. If P < P and P = P then (...) Cb ≤ Cb; if P = P and P < P then Cb ≥ Cb. Cb – Cb is fully determined by Cb and Cbe – Cbe; if Cb = 0 then Cb + Cbe = 0. If P = P then Cb = Cb. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Beautiful Soul:From Hegel to BeckettDrew Milne (bio)The "beautiful soul," lacking an actual existence, entangled in the contradiction between its pure self and the necessity of that self to externalize itself and change itself into an actual existence, and dwelling in the immediacy of this firmly held antithesis—an immediacy which alone is the middle term reconciling the antithesis, which has been intensified to its pure abstraction, and is (...) pure being or empty nothingness—this "beautiful soul," then, being conscious of this contradiction in its unreconciled immediacy, is disordered to the point of madness, wastes itself in yearning and pines away in consumption.—G. W. F. Hegel, Phenomenology of SpiritThe figure of the beautiful soul marks out a limit of representation. Its persistence is that of a literary fiction which cannot be actualized, but whose imaginative lure is no less powerful for being so resistant to embodiment. The beautiful soul emerges in a shift from philosophical reflections on moral beauty into the romantic novel, but for Robert E. Norton, the history of the beautiful soul is brought to a close by Hegel [139]. Nevertheless, the way this figure stands between philosophy and literature, and between moral agency and the literary imagination, casts shadows over contemporary thought. Unreconciled immediacy, disordered by consciousness of its contradiction and proximity to pure abstraction, becomes the sign of modern art, perhaps most explicitly in the writings of Samuel Beckett. In The Broken Middle, Gillian Rose projects the beautiful soul out of Hegel and Goethe into a speculative account of modern thought's ethical equivocations. For Allen Speight, Hegel's recourse to the awkward literary and novelistic status of the beautiful soul reveals how "inescapable questions discernible in the products of modern literary artists are ones that concern the account we give of our freedom as modern agents" [135]. This essay seeks to unravel some of the contemporary relevance of the beautiful soul, exploring the instability of this figure as a mediation between philosophy and literature, in particular as a tension in the interpretation of Hegel's Phenomenology of Spirit.The difficulties posed by the beautiful soul for interpreting Hegel can be gleaned from Terry Pinkard's impressively lucid survey German Philosophy, 1760-1860. Pinkard notes how Hegel's discussion of the beautiful soul in the Phenomenology of Spirit "makes oblique reference to Goethe, Friedrich Schlegel, Fichte, Fries, Novalis, perhaps Rousseau, and maybe even Hölderlin" [240n19] before ascribing centrality in Hegel's discussion to Jacobi's novel Waldemar. Oblique reference folds into a structure whose indeterminacy concerns both the freedom claimed by literary representations of the beautiful soul, and the inability of this freedom to amount to more than a confession of conceptual paralysis or impotence. The beautiful soul proves resistant to interpretation, a literary-philosophical compound that destabilizes conventions of referentiality. The beautiful soul threatens to dissolve philosophy from the perspective of an inward delicacy of moral feeling, claiming [End Page 63] [Begin Page 65] the authenticity of a subjectivity that will do no wrong and knows no other as an object on which to act. Philosophical interpretations are often too brusque with the reflexive irony through which the beautiful soul is represented, or insufficiently literal-minded to capture its content as form. In turn, the self-critical claims of literary representation often dissolve into an ironic indifference to determinate consequences.The beautiful soul, however, can hardly be said to have existed outside its representation in writing. It recurs in manifold guises more as an aspiration to be, or appear, morally sensitive but incapable of action. Donald Phillip Verene sketches its background in the Romantic movement but suggests that: "The beautiful soul is not difficult to understand, as Hegel sketches it in the several pages he devotes to it. We are familiar in ordinary experience with types of persons that approximate to the stance of the beautiful soul, that is, if we keep polite company and associate from time to time with delicate people" [100-01]. Anyone who has spent time with aesthetes or poets who claim a delicacy of moral insight without feeling the need of justification or labor to actualize their insights knows the ills this shape of...

This essay explores the faultlines, poetic pressures and social structures of feeling determining poetry “after” Hiroshima. Nuclear bombs, accidents and waste pose theoretical and poetic challenges. The argument outlines a model of nuclear implicature that reworks Gricean conversational implicature. Nuclear implicature helps to describe ways in which poems “represent” nuclear problems implicitly rather than explicitly. Metonymic, metaphorical, and grammatical modes of implication are juxtaposed with recognition of social attitudes complicit with nuclear problems. Mushroom and lichen metaphors are analysed and distinguished. (...) There are brief accounts of The Chernobyl Herbarium, The Nuclear Culture Source Book and poems by Aidan Semmens, Lorine Niedecker, George Oppen, Denise Levertov, Adrienne Rich, Allen Ginsberg and Gerry Loose. The argument attempts to keep open the fragile agency of writing in poems that confront nuclear power. Poetry after Hiroshima is also contrasted with Adorno’s provocative questions about poetry after Auschwitz, amid Cold War arguments that have distorted recognition of the reality of nuclear production. The essay concludes by considering the emergence of poetry within E.P. Thompson’s theoretical account of “Exterminism,” sketching ways in which poetics and theory might inform both the nuclear imagination and the difficulties of nuclear song. (shrink)

In his article ‘A Cavalry Unit in the Army of Antigonus Monophthalmus: Asthippoi’, N. G. L. Hammond argues that the reading of the manuscript R at Diodorus 19. 29. 2 should be retained and that we should read ⋯π⋯ π⋯σι δ⋯ το⋯ς τε ⋯σθ⋯ππους ⋯νομαζομ⋯νους κα⋯ τοὺς ⋯κ τ⋯ν ἄνω κατοικο⋯ντων ⋯κτακοσιο⋯ς. The readings of F and its copy X, ⋯νθ⋯ππους, and the commonly accepted conjecture of Wesseling ⋯μɸ⋯ππους, should both be abandoned. Hammond's arguments for retaining this reading are that (...) between the variant readings of R and F, R ‘is the more often correct’ ; ⋯σθ⋯ππους, the reading of R, is preferable to F's ⋯νθ⋯ππους on the principle of ‘lectio difficilior’; the ‘difficulty’ of his lectio difficilior is made less by the arguments presented by A. B. Bosworth, 245 ff.), for the restoration at several places in the text of Arrian's Anabasis the word ⋯σθ⋯ταιροι, in place of the editorial emendation of πεζ⋯ταιροι. ‘For just as asthetairoi meant an élite group of Macedonian infantrymen,’ says Hammond, ‘so asthippoi should mean an élite group of Macedonian cavalrymen.’ He then proceeds to examine the passage and its context in an attempt to find confirmation of this proposition and comes to the conclusion that Diodorus' text says that there were 800 cavalrymen, broken into two groups, the asthippoi and ‘the men from the up-country settlers’; these, though having different names, had a close relationship to each other, as is shown by their being brigaded together. Following his derivation of asthetairoi as meaning ‘townsmen-companions’, i.e. companions recruited from the towns of Upper Macedonia, he argues that asthippoi were cavalry recruited from the towns of Upper Macedonia and that τοὺς ⋯κ τ⋯ν ἄνω κατοικο⋯ντων means ‘the sons of settlers in up-country Macedonia’. These 800, says Hammond, were both among Antigonus' best troops and ‘were Macedonians from Europe’. We thus appear, on Hammond's interpretation, to have here a group of 800 Macedonian élite cavalrymen, all of whom were recruited in Upper Macedonia's townships, but of whom some were chosen to be the cavalry-equivalent of the élite ‘townsmen-companions’ by their title of ‘townsmen-cavalry’, whilst the others, similarly recruited – but perhaps of a younger generation? – had no particular distinguishing title beyond ‘sons of settlers in up-country Macedonia’.Now, while it would be exciting to be able to add another one, possibly two Macedonian cavalry units to the Macedonian army of Philip, Alexander and the Successors, there are several aspects of Hammond's arguments that, it seems to me, are less than convincing. Thus, whilst it seems beyond reasonable doubt that ⋯σθ⋯ταιροι should be retained in the text of Arrian, appearing, as it does, six times, this is not an argument that ⋯σθ⋯ππους should be read in Diodorus' text. Both it and F's reading of ⋯νθ⋯ππους are hapax legomena and it is possible that both readings are wrong. But even if we retain ⋯σθ⋯ππους as the correct reading, Hammond's explanation of its meaning is open to objection on several counts. (shrink)

Standard models of adolescent risk taking posit that the cognitive abilities of adolescents and adults are equivalent, and that increases in risk taking that occur during adolescence are the result of socio emotional differences in impulsivity, sensation seeking, and lack of self-control. Fuzzy-trace theory incorporates these socio emotional differences. However, it predicts that there are also cognitive differences between adolescents and adults, specifically that there are developmental increases in gist-based intuition that reflects understanding. Gist understanding, as opposed to verbatim-based analysis, (...) generally has been hypothesized to have a protective effect on risk taking in adolescence. Gist understanding is also an essential element of informed consent regarding risks in medical decision- making. Evidence thus supports the argument that adolescents’ status as mature minors should be treated as an exception rather than a presumption, because accuracy in verbatim analysis is not mature gist understanding. Use of the exception should be accompanied by medical experts’ input on the bottom-line gist of risks involved in treatment. (shrink)

This paper examines the thoughts and early career of the astrophysicist and cosmologist E. A. Milne. Although Milne only turned to cosmology in 1932, many of the ideas that characterised his heterodox system of world physics can be traced back to his works from the 1920s. Contrary to what has been stated in the literature, we argue that Milne was familiar with and interested in cosmology even before 1932. The relationship between mathematics and physics, an important topic (...) in Milne's cosmophysics, was the subject of an unpublished paper he gave in 1922. We place the paper in its historical context and comment on its relevance for Milne's later work. An annotated transcript of the address is included as an accompanying paper under the title 'The Relations of Mathematics to Science'. (shrink)

The various cosmological proposals by Einsteinian relativists seek to show the structure of the world as a consequence of the basic notions of relativity. In particular, the irrelevance of the state of motion of an observer to his description of the fundamental laws of nature is to be maintained. Furthermore, gravity is understood as being a description of the fact that particles move along certain minimal paths in non-Euclidean space. In this theory, the effect of one material particle on another (...) particle in the old-fashioned sense of gravitational attraction becomes indirect; that is, a particle moves on a minimal path in a space having a degree of curvature dependent on the material entities which exist in it, rather than having its path bent by the attraction between it and other material bodies, all of them existing in an absolute or receptacle-like space.

Plato is one of the key ancient authors studied by both classicists and philosophers. This long-awaited new edition contains seven of the dialogues of Plato, and is the first in the five-volume complete edition of his works in the Oxford Classical Texts series. The result of many years of painstaking scholarship, the new volume will replace the now nearly 100 year old original edition, and is destined to become just as long-lasting a classic.

There are distinctive methodological and conceptual challenges in rare and severe event (RSE) forecast verification, that is, in the assessment of the quality of forecasts of rare but severe natural hazards such as avalanches, landslides or tornadoes. While some of these challenges have been discussed since the inception of the discipline in the 1880s, there is no consensus about how to assess RSE forecasts. This article offers a comprehensive and critical overview of the many different measures used to capture the (...) quality of categorical, binary RSE forecasts – forecasts of occurrence and non-occurrence – and argues that of skill scores in the literature there is only one adequate for RSE forecasting. We do so by first focusing on the relationship between accuracy and skill and showing why skill is more important than accuracy in the case of RSE forecast verification. We then motivate three adequacy constraints for a measure of skill in RSE forecasting. We argue that of skill scores in the literature only the Peirce skill score meets all three constraints. We then outline how our theoretical investigation has important practical implications for avalanche forecasting, basing our discussion on a study in avalanche forecast verification using the nearest-neighbour method (Heierli et al., 2004). Lastly, we raise what we call the “scope challenge”; this affects all forms of RSE forecasting and highlights how and why working with the right measure of skill is important not only for local binary RSE forecasts but also for the assessment of different diagnostic tests widely used in avalanche risk management and related operations, including the design of methods to assess the quality of regional multi-categorical avalanche forecasts.
