This essay considers and evaluates recent results and arguments from classical chaotic systems theory and non-relativistic quantum mechanics that pertain to the question of whether our world is deterministic or indeterministic. While the classical results are inconclusive, quantum mechanics is often assumed to establish indeterminism insofar as the measurement process involves an ineliminable stochastic element, even though the dynamics between two measurements is considered fully deterministic. While this latter claim concerning the Schrödinger evolution must be qualified, the former fully depends (...) on a resolution of the measurement problem. Two alleged proofs that nature is indeterministic, relying, in turn, on Gleason's theorem and Conway and Kochen's recent 'free will theorem', are shown to be wanting qua proofs of indeterminism. We are thus left with the conclusion that the determinism question remains open. (shrink)

This Handbook contains forty essays by an international team of experts on the antecedents, the content, and the reception of the Dionysian corpus, a body of writings falsely ascribed to Dionysius the Areopagite, a convert of St Paul, but actually written about 500 AD. The first section contains discussions of the genesis of the corpus, its Christian antecedents, and its Neoplatonic influences. In the second section, studies on the Syriac reception, the relation of the Syriac to the original Greek, (...) and the editing of the Greek by John of Scythopolis are followed by contributions on the use of the corpus in such Byzantine authors as Maximus the Confessor, John of Damascus, Theodore the Studite, Niketas Stethatos, Gregory Palamas, and Gemistus Pletho. In the third section attention turns to the Western tradition, represented first by the translators John Scotus Eriugena, John Sarracenus, and Robert Grosseteste and then by such readers as the Victorines, the early Franciscans, Albert the Great, Aquinas, Bonaventure, Dante, the English mystics, Nicholas of Cusa, and Marsilio Ficino. The contributors to the final section survey the effect on Western readers of Lorenzo Valla's proof of the inauthenticity of the corpus and the subsequent exposure of its dependence on Proclus by Koch and Stiglmayr. The authors studied in this section include Erasmus, Luther and his followers, Vladimir Lossky, Hans Urs von Balthasar, and Jacques Derrida, as well as modern thinkers of the Greek Church. Essays on Dionysius as a mystic and a political theologian conclude the volume. (shrink)

Spacetime as we know and love it is lost in most approaches to quantum gravity. For many of these approaches, as inchoate and incomplete as they may be, one of the main challenges is to relate what they take to be the fundamental non-spatiotemporal structure of the world back to the classical spacetime of GR. The present essay investigates how spacetime is lost and how it may be regained in one major approach to quantum gravity, loop quantum gravity.

The detailed interpretation and translation of Nietzsche’s early Latin odes clearly show that Horace’s lyric poetry has an exemplary function for the development of Nietzsche’s own poetic language. Even in his later works, such as Twilight of the Idols and the Dionysos-Dithyrambs, Nietzsche’s poetic style and rhetorical strategies remain indebted to his early attempts to emulate classical Latin poetry when he was a pupil at the Pforta boarding school.

I model sequential decisions over multiple interconnected propositions and investigate path-dependence in such decisions. The propositions and their interconnections are represented in propositional logic. A sequential decision process is path-dependent if its outcome depends on the order in which the propositions are considered. Assuming that earlier decisions constrain later ones, I prove three main results: First, certain rationality violations by the decision-making agent—individual or group—are necessary and sufficient for path-dependence. Second, under some conditions, path-dependence is unavoidable in decisions made by (...) groups. Third, path-dependence makes decisions vulnerable to strategic agenda setting and strategic voting. I also discuss escape routes from path-dependence. My results are relevant to discussions on collective consistency and reason-based decision-making, focusing not only on outcomes, but also on underlying reasons, beliefs, and constraints. (shrink)

More often than not, recently popular structuralist interpretations of physical theories leave the central concept of a structure insufficiently precisified. The incipient causal sets approach to quantum gravity offers a paradigmatic case of a physical theory predestined to be interpreted in structuralist terms. It is shown how employing structuralism lends itself to a natural interpretation of the physical meaning of causal set theory. Conversely, the conceptually exceptionally clear case of causal sets is used as a foil to illustrate how a (...) mathematically informed rigorous conceptualization of structure serves to identify structures in physical theories. Furthermore, a number of technical issues infesting structuralist interpretations of physical theories such as difficulties with grounding the identity of the places of highly symmetrical physical structures in their relational profile and what may resolve these difficulties can be vividly illustrated with causal sets.

Approaches to quantum gravity often involve the disappearance of space and time at the fundamental level. The metaphysical consequences of this disappearance are profound, as is illustrated with David Lewis's analysis of modality. As Lewis's possible worlds are unified by the spatiotemporal relations among their parts, the non-fundamentality of spacetime---if borne out---suggests a serious problem for his analysis: his pluriverse, for all its ontological abundance, does not contain our world. Although the mere existence---as opposed to the fundamentality---of spacetime must be (...) recovered from the fundamental structure in order to guarantee the empirical coherence of the non-spatiotemporal fundamental theory, it does not suffice to salvage Lewis's theory of modality from the charge of rendering our actual world impossible.

Deep Brain Stimulation (DBS) represents a key area of neuromodulation that has gained wide adoption for the treatment of neurological and experimental testing for psychiatric disorders. It is associated with specific therapeutic effects based on the precision of an evolving mechanistic neuroscientific understanding. At the same time, there are obstacles to achieving symptom relief because of the incompleteness of such an understanding. These obstacles are at least in part based on the complexity of neuropsychiatric disorders and the incompleteness of DBS (...) devices to represent prosthetics that modulate the breadth of pathological processes implicated in these disorders. Neuroprostheses, such as an implanted DBS system, can have vast effects on subjects in addition to the specific neuropsychiatric changes they are intended to produce. These effects largely represent blind spots in the current debate on neuromodulation. Anthropological accounts can illustrate the broad existential dimensions of patients’ illness and responses to neural implants. In combination with current neuroscientific understanding, neuropsychiatric anthropology may illuminate the possibilities and limits of neurodevices as technical “world enablers”. (shrink)

Globalization arguably generated a governance gap that is being filled by transnational rule-making involving private actors among others. The democratic legitimacy of such new forms of governance beyond nation states is sometimes questioned. Apart from nation-centered democracies, such governance cannot build, for example, on representation and voting procedures to convey legitimacy to the generated rules. Instead, alternative elements of democracy such as deliberation and inclusion require discussion to assess new instruments of governance. The recently published standard ISO 26000 is an (...) interesting example of transnational governance. ISO 26000 was developed in a lengthy multiorganizational process for the purpose of giving guidance on the social responsibility of organizations. By assessing the specific case of ISO 26000, this study sheds light on the question of how legitimacy beyond nation-state democracy is ensured or constricted. Centering on the idea of deliberate democracy and democratic legitimacy, the study offers in-depth insights on the normative legitimacy of the development process of ISO 26000. Positioned on the interface of business studies and public policy, this article contributes to the academic literature on transnational governance and on the role of multistakeholder processes in shaping the role of business in society.

This article examines the methodology of a core branch of contemporary political theory or philosophy: “analytic” political theory. After distinguishing political theory from related fields, such as political science, moral philosophy, and legal theory, the article discusses the analysis of political concepts. It then turns to the notions of principles and theories, as distinct from concepts, and reviews the methods of assessing such principles and theories, for the purpose of justifying or criticizing them. Finally, it looks at a recent debate (...) on how abstract and idealized political theory should be, and assesses the significance of disagreement in political theory. The discussion is carried out from an angle inspired by the philosophy of science. (shrink)

In response to Koplin and Wilkinson, I argue, first, that the uncertain clinical prospects of human-pig chimera based transplantation makes the reason to spend resources for clarifying whether such practice might imply serious ethical breach due to enhanced cognitive capacities of the chimeras rather weak. T he benefits of further pursuing this avenue of research is so uncertain, so that taking even very unclear risks of serious ethical breach (thus in need of clarification for justification of the research) is not (...) worth the price in terms of spent resources, and therefore only limited resources should be spent to clarify such risk before the project is abandoned due to unacceptable risks. Second, I argue that as there are some reason to pursue this avenue further (and thus investigate the risk in question), the analogy to the notion of halting all farming of larger animals for food does not hold up. The reason is that we do not need to probe any further any comparable risk to know that such farming practices should be halted. A fundamental underlying issue to the question discussed by Koplin and Wilkinson1 in this paper is formulated when they write: > We should therefore be confident that human-pig chimeras would lack morally relevant cognitive capacities before setting out to use them as a source of transplantable human organs. This leaves open the question of how confident …. (shrink)

One cannot scrutinize mediality in a pre-media age without referring to the complex issue of Christology. The idea of Christ as medium and mediator concerns not only particular theological questions but also general issues of translation and transference, as well as models of word and image. This paper sketches first the notion of Christ′s mediality up to early Scholasticism and then highlights the new conceptual patterns developed by Bonaventure (Collationes in Hexaemeron) and Nicolas of Cusa (De visione dei).

Most approaches to quantum gravity suggest that relativistic spacetime is not fundamental, but instead emerges from some non-spatiotemporal structure. This paper investigates the implications of this suggestion for the possibility of time travel in the sense of the existence of closed timelike curves in some relativistic spacetimes. In short, will quantum gravity reverse or strengthen general relativity’s verdict that time travel is possible?

The ideal of scientific openness — i.e. the idea that scientific information should be freely accessible to interested parties — is strongly supported throughout the scientific community. At the same time, however, this ideal does not appear to be absolute in the everyday practice of science. In order to get the credit for new scientific advances, scientists often keep information to themselves. Also, it is common practice to withhold information obtained in commissioned research when the scientist has agreed with his (...) or her employer to do so. The secrecy may be intended for ever, as in the military area, but also temporarily until a patent application has been made. The paper explores to what extent such secrecy is undesirable, as seems to be suggested by the ideal of scientific openness. Should this ideal be interpreted as having certain exceptions which make the above-mentioned practices acceptable? Are there, on closer inspection, good arguments for the ideal of scientific openness, and for officially upholding it? Possible versions of the ideal of scientific openness are explored and the issue is found to be rather complex, allowing for wide variations depending on the acting parties, beneficiaries, types of information and moral requirements involved. We conclude that the arguments usually given in favour of this ideal are weaker than what seems to be generally believed, and that, on closer inspection, they leave plenty of room for exceptions to it. These exceptions only partly cover the actual practice of withholding scientific information, and there may still be good reason to advocate, teach and enforce the ideal of scientific openness within the scientific community.

Resumo: Esse ensaio buscará sondar as relações entre filosofia e literatura, no pensamento de Gilles Deleuze, a despeito de sua parceria conjunta com Félix Guattari, atentando tanto para as concepções de escrita expressas ao longo de sua obra quanto para o modo como essas concepções teriam influenciado o estilo de seus escritos filosóficos. Partindo da premissa deleuziana de que a escrita possui um acentuado lastro clínico, sendo a responsável pela elaboração de um diagnóstico das forças capazes de aprisionar ou calar (...) a vida, procurar-se-á esmiuçar as ressonâncias desse lastro clínico, na concepção de filosofia como ato criativo, elaborada pelo autor. Como hipótese a ser aqui trabalhada, defende-se que a escrita deleuziana - compreendida como portadora de uma literalidade, conforme sustenta François Zourabchivili, ou como encrustada de uma poética imanentista, tal qual sugere Anita Costa Malufe - procuraria produzir uma zona de vizinhança ou indiscernibilidade entre a escrita filosófica, de caráter mais exegético, e a escrita literária, mais afectiva, de modo a produzir um deslocamento na relação do leitor com o ato de pensar.: In this essay we pretend to study the relationship between philosophy and literature in Gilles Deleuze’s thought, despite of his partnership with Félix Guattari, mapping the conceptions of writing throughout his work and considering the influence of these conceptions to forge a certain style in his philosophical texts. Starting from the deleuzian premise that writing has a strong clinical backing - being responsible for the elaboration of a diagnosis of the forces liable to imprison or silence life -, we will examine the resonances of this clinical backing in his conception of philosophy as a creative act. Our hypothesis is that the deleuzian writing - having a certain literality, as François Zourabchivili argues, or encrusted with an immanentism poetics, as Anita Costa Malufe suggests - would produce a so-called neighborhood zone or zone of indiscernibility between philosophical writing, with a more exegetical character, and literary writing, which is more affective, in order to produce a shift in the reader’s relationship with the act of thinking.

If there is a specifically rhetorical approach to argumentation, I believe it is one that studies argumentation that is specifically rhetorical. So if we want to ask, “What is the rhetorical approach to argumentation?” we should first ask, “What is rhetorical argumentation?” It is worthwhile focusing on this question because various misleading definitions of rhetorical argumentation have been in circulation for almost as long as rhetoric has existed. Some misleading definitions see the defining property of rhetorical argumentation in the arguer’s (...) aim. And that aim, which is often assumed to override all the arguer’s other considerations, is strategic: to persuade his hearer(s) by any available means and .. (shrink)

We investigate Kerr–Newman black holes in which a rotating charged ring-shaped singularity induces a region which contains closed timelike curves (CTCs). Contrary to popular belief, it turns out that the time orientation of the CTC is oppo- site to the direction in which the singularity or the ergosphere rotates. In this sense, CTCs “counter-rotate” against the rotating black hole. We have similar results for all spacetimes sufficiently familiar to us in which rotation induces CTCs. This motivates our conjecture that perhaps (...) this counter-rotation is not an accidental oddity particular to Kerr–Newman spacetimes, but instead there may be a general and intuitively comprehensible reason for this.

Douglas Walton has done extensive and valuable work on the concepts of presumption and practical reasoning. However, Walton’s attempt to model practical reasoning as presumptive is misguided. The notions of “inference” and of the burden of proof shifting back and forth between proponent and respondent are misleading and lead to counterintuitive consequences. Because the issue in practical reasoning is a proposal, not a proposition, there are, in the standard case, several perfectly good reasons on both sides simultaneously, which implies that (...) argument appraisal necessarily contains a subjective element—a fact argumentation theory needs to conceptualize.

Within child and adolescent psychiatry, there are a number of potential dilemmas pertaining to diagnosis, treatment, the protection of the child, as well as the child's own developing intelligence and moral judgement. Diagnostic Dilemmas in Child and Adolescent Psychiatry is the first in the IPPP series to explore this highly complex topic.

Distributed cognition refers to processes which are (i) cognitive and (ii) distributed across multiple agents or devices rather than performed by a single agent. Distributed cognition has attracted interest in several fields ranging from sociology and law to computer science and the philosophy of science. In this paper, I discuss distributed cognition from a social-choice-theoretic perspective. Drawing on models of judgment aggregation, I address two questions. First, how can we model a group of individuals as a distributed cognitive system? Second, (...) can a group acting as a distributed cognitive system be ‘rational’ and ‘track the truth’ in the outputs it produces? I argue that a group’s performance as a distributed cognitive system depends on its ‘aggregation procedure’ – its mechanism for aggregating the group members’ inputs into collective outputs – and I investigate the properties of an aggregation procedure that matter.

We prove completeness for some language-theoretic models of the full Lambek calculus and its various fragments. First we consider syntactic concepts and syntactic concepts over regular languages, which provide a complete semantics for the full Lambek calculus \. We present a new semantics we call automata-theoretic, which combines languages and relations via closure operators which are based on automaton transitions. We establish the completeness of this semantics for the full Lambek calculus via an isomorphism theorem for the syntactic concepts lattice (...) of a language and a construction for the universal automaton recognizing the same language. Finally, we use automata-theoretic semantics to prove completeness of relation models of binary relations and finite relation models for the Lambek calculus without and with empty antecedents and \), thus solving a problem left open by Pentus.

The fact that we ought to prefer what is comparatively more likely to be good, I argue, does, contrary to consequentialism, not rest on any evaluative facts. It is, in this sense, a deontological requirement. As such it is the basis of our valuing those things which are in accordance with it. We value acting (and believing) well, i.e. we value acting (and believing) as we ought to act (and to believe). In this way, despite the fact that our interest (...) in justification depends on our interest in truth, we value believing with justification on non-instrumental grounds. A deontological understanding of justification, thus, solves the Value of Knowledge Problem. (shrink)
