The Republic is the quintessential Platonic dialogue concerning justice and politics. This great ten-book work ends with the Myth of Er. This myth has been a source of controversy throughout history. Some claim Plato wrote it, while others claim it is a forgery. Still others claim it is a lost story saved in the annals of history only by Plato. In response to the limited scholarship about Er, Mr. Chrysovalantis Petridis undertook a painstaking analysis of both the Republic (...) and Er in an attempt to put to rest any debate concerning them. Not only is the myth of Er crucial for understanding the Republic but it also is key to understanding Plato's project in this dialogue. Without the myth, the ideas Plato w anted to impart in this text cannot be fully understood. Er means "Spring" in Ancient Greek, and the Republic contains the secret teachings concerning the dawn of Socratic philosophy: it heralds a new way of thinking. Socratic philosophy has influenced religion, politics and society ever since. Philosophy has come to mean Socratic philosophy, especially for all who subscribe to Plato's way of thinking. The Socratic method is considered the backbone of contemporary education and Plato's Academy the forerunner of current education. Mr. Petridis' book, Plato's Mythologizing the Myth of Er, exposes the themes and ideas brought to life in the Myth of Er. The Republic is of political, social and religious importance and has influenced every way of thinking and discipline since its conception. One cannot fully understand the impact of Plato, Socrates and Aristotle without it. Thus, Mr. Petridis' book may be one of the most important texts written this century concerning Plato's works. It is a must-read for anyone who desires to know Plato or Socrates and understand why their influence has changed and shaped the world ever since. (shrink)

This paper examines the impact of three culturally endorsed leadership prototypes on bank lending corruption. We bring together studies that approach the corruption of bank lending officers from the perspective of a principal-agent problem and studies from the leadership literature, suggesting leadership as an alternative to contractual solutions to agency problems. We hypothesize, based on these views, that culturally endorsed leadership styles that improve (worsen) the leader-subordinate relationships have a negative (positive) effect on bank lending corruption. Using a sample of (...) around 3,500 firms from 36 countries, we find that the prosocial leadership prototype and the nonautonomous leadership prototype do not matter, whereas the self-serving leadership prototype has a positive and statistically significant effect on bank lending corruption. These findings are robust to the inclusion of various control variables in the regressions, and alternative estimation approaches, including ones that account for endogeneity concerns. Furthermore, we find that the power of bank regulators and the age of the credit information sharing mechanism play a moderating role in the relationship between the self-serving leadership prototype and bank lending corruption.

Ce livre constitue une étude de la topographie de la ville d'Argos à l'époque protobyzantine (IVe–VIIe siècles). Il s'agit en effet d'une mise au point de l'état des recherches archéologiques, essentiellement des fouilles de sauvetage, menées par le Service Archéologique grec dont l'auteur fut épimélète responsable du département d'Argos pendant de longues années et jusqu'à sa mort précoce en 1998.

A study of the topography of Delphi in late antiquity in concert with a study of the pottery, chiefly discovered during recent excavations, casts decisive light on a period in the sites history that is little known and largely ighored in the bibliography. Delphi thus appears as provincial town of moderate size, but more extensive than in previous periods, especially towards the west. The sacred area was transformed into an urban area and the most imposing buildings, public and private, were (...) regrouped around the sanctuary enclosure. The stratigraphie data and the finds, both ceramic and other, indicate a life that was rather calm and comfortable until the last quarter of the 6th c, then an interruption followed by a resumption of activities until the first quarter of the 7th c, when the town was abandoned by its inhabiants. Several types of pottery were made on the spot, evidenced by the discovery of a potter's kiln, refuse dumps, moulds and wasters. (shrink)

In this paper two accounts of Reichenbachian common cause systems are compared. Examples are provided which show that Hofer-Szabó and Rédei account and Hofer-Szabó et al. account is compatible, with but not equivalent, to Mazzola’s. Moreover, the difference of the two accounts with respect to their explanatory adequacy is discussed, in the light of Salmon’s statistical-relevance approach to statistical explanation.

Dans la Delphes de l’époque protobyzantine, l’expression artistique et artisanale fait preuve d’une vive interaction entre les Delphiens et leurs homologues de villes proches ou lointaines. La céramique locale plus précisément, bien étudiée et circonscrite dans le temps, couvre un large éventail de produits de bonne qualité, déjà au ive s. de n. è., mais surtout aux vie et viie s. Quant à la céramique importée, amphores, lampes, sigillées et céramique peinte sont examinées ici pour la première fois en détail, (...) dans le souci de compléter l’image des objets en terre cuite utilisés dans cette ville moyenne de la Grèce Centrale. Les rapports commerciaux entre Delphes et certaines autres villes de la péninsule grecque et des îles y sont étudiés, en même temps que la présence dans toutes ces villes des grandes productions méditerranéennes. Cette étude nous permet d’inscrire Delphes dans un cadre commercial précis, la rapprochant des villes de la Grèce Centrale et du Péloponnèse où les produits africains l’emportent sur les importations micrasiatiques.

Les lampes corinthiennes des Ier-IIIe s. apr. J.-C. découvertes à Delphes proviennent essentiellement des nécropoles et de quelques contextes urbains fouillés systématiquement dans les années 1990. Elles constituent une preuve directe des rapports entre Delphes et la capitale de l’Achaïe, Corinthe, rapports qui n’ont pas eu de suite après le IIIe s. Ces lampes portent toutes les caractéristiques techniques du type (forme, mode de fabrication, pâte) et se distinguent par une certaine variété dans le décor des médaillons, inspiré par la (...) mythologie ou par la vie quotidienne. Quatorze noms de potiers ont été recensés sur les bases conservées. Plus d’un siècle après une très brève publication par Perdrizet et quarante ans après les articles fondamentaux sur les lampes corinthiennes de Bruneau, l’approche de ce corpus sous un prisme nouveau nous offre l’occasion de reprendre la discussion sur la morphologie, sur les ateliers et surtout sur les villes où ce type de lampes était produit ; elle nous permet aussi une nouvelle interprétation du décor de plusieurs de ces lampes.

Η πολύ διαδεδομένη άποψη ότι το μεσοβυζαντινό χωριό Καστόριον, όπου γεννήθηκε ο Όσιος Λουκάς, ταυτίζεται με το χωριό Καστρί και κατ' επέκταση με τους αρχαίους Δελφούς προσκρούει στα αρχαιολογικά δεδομένα: στον μέχρι τώρα ανασκαφέντα αρχαιολογικό χώρο επικρατεί παντελής έλλειψη μεσοβυζαντινών καταλοίπων. Ξεκινώντας από την ετυμολογική εξέταση των όρων Καστόριον και Καστρί και μετά από μια σειρά συλλογισμών, καταλήγουμε να αποσυνδέσουμε το μεσαιωνικό Καστόριον από το Καστρί που κατέλαβε το χώρο των αρχαίων και πρωτοβυζαντινών Δελφών.

Le petit lot de lampes corinthiennes du 11e et me siècle de notre ère qui sont publiées dans cet article provient du site de «Kritika», appartenant au cimetière Nord de Corinthe. Leur présentation est suivie de quelques remarques générales concernant leur diffusion en Grèce et en dehors de celle-ci (illustrée par deux cartes), les ateliers de fabrication (origine des potiers, organisation interne, relations entre les ateliers, commercialisation des lampes), leur présence dans les tombes.

Recently, Clifton and Halvorson have tried to salvage a particle phenomenology in the absence of particle ontology within algebraic relativistic quantum field theory. Their idea is that the detection of a particle is the measurement of a local observable which simulates the measurement of an almost local observable that annihilates the vacuum. In this note, we argue that the measurements local particle detections are supposed to simulate probe radically holistic aspects of relativistic quantum fields. We prove that in an axiomatic (...) (Haag-Araki) quantum field theory on Minkowski spacetime, formulated in a Hilbert space $\mathcal{H}$ , there is no positive observable C, with norm less than or equal to 1, satisfying the conditions: (1) the expectation value of C in the vacuum state Ω is zero, (2) there is at least one vector state Ψ in $\mathcal{H}$ in which the expectation value of C is different from zero, and (3) there exists at least one spacetime region $\mathcal{O}$ such that the non-selective measurement of C leaves the expectation values of all observables in the local algebra of that region unaltered regardless of the state the system is in. The result reveals a tension between intuitions regarding localization and intuitions regarding causality: to save “particle phenomena” in the absence of particle ontology, one has to feign “particle” detectors with “good” properties as to locality but “bad” behavior as to causality.

The Problem of Induction This article discusses the problem of induction, including its conceptual and historical perspectives from Hume to Reichenbach. Given the prominence of induction in everyday life as well as in science, we should be able to tell whether inductive inference amounts to sound reasoning or not, or at least we should be … Continue reading Induction, The Problem of →.

To consider metaphysical claims a priori and devoid of empirical content, is a rather commonplace received opinion. This paper attempts an exploration of a contemporary philosophical heresy: it is possible to test metaphysical claims if they play an indispensable role in producing empirical success, i.e. novel predictions. To do so one, firstly, needs to express the metaphysical claims employed in the logico-mathematical language of a scientific theory, i.e. to explicate them. Secondly, one should have an understanding of what it is (...) to test and to verify or to falsify a metaphysical claim. Finally, one also need to consider the philosophical practice of testing a metaphysical claim. These three aspects are introduced in this paper and they are illustrated by means of the metaphysical concept of common cause and the principle of the common cause. (shrink)

In this work we try to study theories of causation based upon causal processes and causal interactions in the context of classical and quantum physics. Our central aim is to find out whether such causal theories are compatible with the world picture suggested by contemporary theories of physics. In the first part, we review, compare and try to place among more general taxonomical schemes, the causal theories by Russell (the causal lines approach), Reichenbach (mark method, probabilistic causality and the principle (...) of common cause), Salmon (mark method, structure, invariant and conserved quantities approaches) and Dowe (conserved quantity theory). In the second part of the work, we deal with some problems that process theories of causation face whenever one tries to define, rigorously, causal concepts (e.g. “causal process” or “conjunctive common cause”) in the context of classical relativistic physical theories (van Dam – Wigner particle theory, the free Klein-Gordon field, classical electromagnetic theory) as well as quantum theories (algebraic relativistic quantum field theory). In this vein, special attention has been given to the locality problem in physical theories as it emerges from the structure of local classical the quantum theories (semantic locality), the relation between global and local conditions for physical systems (global and local determinism) as well as the problem of action at a distance, which is of central importance for the theories of causation under examination (Bell’s inequalities, EPR paradox, Reeh-Schlieder theorem and local independence conditions). We argue for three different theses: first, there are physical theories in the context of which it is impossible even to formulate the necessary physical hypotheses that allow us to define basic causal concepts and causal principles; second, there are physical theories which allow us to formulate these hypotheses only ad hoc; finally, in some cases it is necessary to revise basic causal principles and concepts bequeathed by the philosophical tradition.

In this paper, we attempt to explicate Salmon’s idea of a causal process, as defined in terms of the mark method, in the context of C*-dynamical systems. We prove two propositions, one establishing mark manifestation infinitely many times along a given interval of the process, and, a second one, which establishes continuous manifestation of mark with the exception of a countable number of isolated points. Furthermore, we discuss how these results can be implemented in the context of the Haag–Araki theories (...) of relativistic quantum fields on Minkowski spacetime. (shrink)

In this paper, I reconstruct an argument of Aristidis Arageorgis against empirical underdetermination of the state of a physical system in a C*-algebraic setting and explore its soundness. The argument, aiming against algebraic imperialism, the operationalist attitude which characterized the first steps of Algebraic Quantum Field Theory, is based on two topological properties of the state space: being T1 and being first countable in the weak*-topology. The first property is possessed trivially by the state space while the latter is highly (...) non-trivial, and it can be derived from the assumption of the algebra of observables’ separability. I present some cases of classical and of quantum systems which satisfy the separability condition, and others which do not, and relate these facts to the dimension of the algebra and to whether it is a von Neumann algebra. Namely, I show that while in the case of finite-dimensional algebras of observables the argument is conclusive, in the case of infinite-dimensional von Neumann algebras it is not. In addition, there are cases of infinite-dimensional quasilocal algebras in which the argument is conclusive. Finally, I discuss Porrmann's construction of a net of local separable algebras in Minkowski spacetime which satisfies the basic postulates of Algebraic Quantum Field Theory. (shrink)

In this note, I discuss the simplicity of rival statistical explanations of a correlation, couched in terms of Reichenbachian Common Cause Systems. Simplicity is analyzed in two components, the so-called intrinsic and contextual simplicity. I show that if one disentangles simplicity from explanatory power then the size of the system provides an adequate for simplicity in both of its dimensions.

I present two relatively independent sets of remarks on common causes and the violation of Bell inequalities in algebraic quantum field theory. The first set of remarks concerns the possibility of reconciling Reichenbachian ideas on common causes with quantum field theory in the face of an already known difficulty: the event shown to satisfy statistical relations for being the common cause of two correlated events has been associated with the union, rather than the intersection, of the backward light cones of (...) the correlated events. I explore a way of overcoming this difficulty by considering the common cause to be a conjunction of suitably located events. But I show that this line of thought too is beset with interpretational problems. My second set of remarks concerns the type of inequality one may derive from the common-common cause hypothesis: I argue, on grounds of interpretation, that the Clauser-Horne type, and not the Bell type, of inequalities emerge more naturally in this context.

Anything other than paraphrasing the well-known Heraclitean aphorism would not be more appropriate to portray the crux of the contribution of the three philosophers of the Budapest School, Gábor Hofer-Szabó, Miklós Rédei and Lázló E. Szabó, in the ongoing discussion of the principle of the common cause . Indeed, ‘common causes love to hide’ and for that reason critics and aspirant falsifiers of PCC find correlations which, at a first level of analysis, might lack a common cause explanation. But as (...) the authors argue such correlations do not amount to disconfirming evidence for the principle, since PCC does not specify where to search for a common cause of a correlation; it just states that there is one. PCC is neither falsifiable, nor verifiable; it is a metaphysical doctrine that can only be assessed for its plausibility in the light of theories of empirical science. This idea fosters the investigation of the existence of common causes of correlations in two fundamental physical t .. (shrink)
