Il volume, inserito nella collana diretta da Franco Todescan “Lex naturalis. Testi scelti di filosofia del diritto medievale”, presenta una sezione antologica di testi marsiliani introdotta da uno studio di Elvio Ancona sulla letteratura critica che nell’ultimo cinquantennio si è occupata del pensiero del Patavino. Lo studio bibliografico, in particolare, nella rivisitazione delle più recenti interpretazioni del Defensor pacis, trova occasione per interrogarsi su alcuni problemi giusfilosofici fondamentali che in quell’opera furono sollevati e sulle soluzioni che vi furono prospettate. In (...) questa prospettiva, dunque, viene esaminata innanzitutto la discussione relativa all’ispirazione di fondo della riflessione di Marsilio, riassumibile nella domanda se egli si debba ritenere “magis aristotelicus” o “magis christianus”, e a quale tipo di aristotelismo o di cristianesimo eventualmente si riferisca. Vengono successivamente considerate le principali teorie fiorite intorno alle grandi tematiche “istituzionali” del Defensor pacis, concernenti l’origine, l’organizzazione e la legislazione della civitas sive regnum, tematiche che sono state affrontate dagli studiosi ricorrendo a concezioni che andavano di volta in volta dal naturalismo al convenzionalismo, dal repubblicanesimo all’assolutismo, dalla teonomia al giuspositivismo. Ci si sofferma quindi sulla diuturna controversia che, con riguardo alla politica religiosa del legislator marsiliano, ha fatto parlare, con linguaggio spesso consapevolmente anacronistico, di “secolarismo” o addirittura “laicismo” e, alternativamente, di “cesaropapismo”. Si conclude infine con la disputa storiografica sulla collocazione del Mainardini tra medioevo e modernità, e con la valutazione delle indicazioni che, in termini di “ideologia marsiliana”, la complessa vicenda ermeneutica esaminata offre per una comprensione unitaria del significato della sua opera.

Welcome to the Post-Truth era-- a time in which the art of the lie is shaking the very foundations of democracy and the world as we know it. The Brexit vote; Donald Trump's victory; the rejection of climate change science; the vilification of immigrants; all have been based on the power to evoke feelings and not facts. So what does it all mean and how can we champion truth in in a time of lies and 'alternative facts'? In this eye-opening (...) and timely book, Post-Truth is distinguished from a long tradition of political lies, exaggeration and spin. What is new is not the mendacity of politicians but the public's response to it and the ability of new technologies and social media to manipulate, polarise and entrench opinion. Where trust has evaporated, conspiracy theories thrive, the authority of the media wilt and emotions matter more than facts. Now, one of the UK's most respected political journalists, Matthew d'Ancona investigates how we got here, why quiet resignation is not an option and how we can and must fight back. (shrink)

: Embryonic stem cells, which have the potential to save many lives, must be recovered from aborted fetuses or live embryos. Although tissue from aborted fetuses can be used without moral complicity in the underlying abortion, obtaining stem cells from embryos necessarily kills them, thus raising difficult questions about the use of embryonic human material to save others. This article draws on previous controversies over embryo research and distinctions between intrinsic and symbolic moral status to analyze these issues. It argues (...) that stem cell research with spare embryos produced during infertility treatment, or even embryos created specifically for research or therapeutic purposes, is ethically acceptable and should receive federal funding.

The Arabic version of the Enneads is the earliest datable text in which appears the term "anniyya", that features in Avicenna’s metaphysics and lies in the background of the Latin definition of the Causa prima as esse tantum, typical of the Liber de Causis. This paper examines some examples of the use of "to be" in the Arabic translation of the Enneads. It also discusses the description of the First Cause as ‘pure Being’ or ‘first Being’ in the Arabic Plotinus, (...) and compares it with the Divine Names of the pseudo-Dionysius. icona . (shrink)

Le traité Περὶ θείων ὀνομάτων de l’élève de Proclus dissimulé sous le nom de ‘Denys l’Aréopagite’— traité qui a été récemment édité en qualité de premier titre de la série Corpus Dionysiacum— est subdivisé en deux grandes parties par un excursus fameux sur le problème de la substantialité des maux. Dans la première partie, contenant les chapitres I-III, l’auteur discute la possibilité des prédications dont l’objet est le premier principe. Dans la deuxième, contenant les chapitres V-XIII, il en présente les (...) ‘noms’. Les deux parties sont séparées par le long excursus sur la nature du mal, qui forme l’objet du chapitre IV. Ce dernier s’ouvre, il est vrai, sur le propos d’examiner la dénomination de ‘Bien’ attribuée au premier principe , si bien que l’on rangerait volontiers ce chapitre dans la deuxième partie, consacrée à la présentation des ‘noms’ de Dieu et à leur commentaire. Il se trouve pourtant que l’auteur a explicitement placé la charnière principale de son traité après l’excursus sur la nature du mal. Au début du chapitre V, en effet, il déclare aborder la question de l’οὑσιωνυμία divine, en démontrant par là concevoir le ‘Bien’ comme une dénomination différente de toute autre, voire antérieure à tous les noms qui sont en relation avec l’οὑσία, et dont l’examen occupe les chapitres V-XIII.

L’idée d’une discontinuité radicale entre l’Un et l’être intelligible a été parfois comprise comme la thèse la plus intéressante de Plotin pour l’histoire de la métaphysique. En effet, à côté de passages où Plotin établit un rapport de ressemblance entre l’effet et la cause, il y en a d’autres où une théorie de la causalité des principes est introduite, selon laquelle le principe « donne ce qu’il n’a pas ». Dans le but d’examiner si cette théorie conduit Plotin à soutenir (...) une discontinuité radicale entre l’Un et l’être intelligible, cet article examine le traité III, 8 [30]. Une critique de Plotin à l’égard de la doctrine alexandriste de la dynamis y est signalée, et deux passages difficiles sont analysés : III, 8 [30], 2. 15-19 et III, 8 [30], 9. 29-32.Modèles de causalité chez Plotin Complete otherness of the One with respect to intelligible Being has been presented as the sharpest Plotinian contribution to the history of metaphysics. As a matter of fact, together with passages where similarity between the effect and the cause is held, there are other passages where a notion of causality is advanced, in which the principle produces « what it does not possess ». Does this involve that according to Plotinus there is complete otherness between the One and intelligible Being? This article focuses on treatise III, 8 [30], showing that it contains a criticism of Alexander of Aphrodisias’ doctrine of dynamis. It deals also with two controversial passages, III, 8 [30], 2. 15-19 and III, 8 [30], 9. 29-32. (shrink)

All’origine della sovranità is a critical reflection on the complex and articolated sequence of events which, in the first half of the fourteenth century, brought to the crisis of Dyonisian hierarchical system and to the modern conception of sovereignty. In fact, the principle superiorem non recognoscere appears for the first time in juridical experience during the dispute about the two powers, when opponents of papal claims perceived the need to create new models of order, by which to replace the hierocratic (...) representation of the hierarchical system. After having considered the different conceptions of Dyonisian order in the late Middle Ages, the Author dwells on the two main contrasting paradigms: Marsilio’s organicism and Dante’s humanism. The first was coupled with clearly conventionalist theses, and led to the supremacy of the sovereignty principle and to a total submission of citizens to the public will; on the contrary, the second heightened persons’ capacity for self-regulation in accordance with a law that is given them with their being, and that directs them both to the beatitudo huius vite and, above all, to the beatitudo vite ecterne. Because of this contrast, through the philosophical arguments of the disputants, the problem of the relation between the two powers emerges in all its dramatic complexity. It wasn’t only a question to recognize preeminences or supremacies, autonomies or subjections, but to pronounce upon the conception itself of political community, of its ordering principle, and of its juridical shape. For this reason the alternative between Dante and Marsilio will mark out the whole subsequent juridical and political experience, up to our days. (shrink)

According to the Thomistic reflection on contingent matters, a conclusion is probabilis when it is arrived to through “dialectical” arguments, in the Aristotelician sense. In particular, for Aquinas dialectics is a method for searching truth also in the specific realm of judicial context, which represents a particular case of probable knowledge. Dialectics, as attends non only to value the reliability of testimonies, but aims more in general to the verification of the facts at stake, ensures the highest probability of the (...) solution to be reached. From the Thomistic perspective, then, one can claim that, if in a trial the acquired evidence is sufficient, the solution arrived to through the dialectical method is, among the many possible, the one which most probably “corresponds” to reality.

The Thomistic doctrine of adequatio seems to endure as a current topic in contemporary debates on the accessibility of truth in trials, since it can account for the objectivity of our knowledge, while avoiding anti-correspondence objections. It can, thus, offer an important contribution to forensic epistemology, in particular in force of the fact that, in conjunction with Thomistic reflections on the certitudo probabilis of witnesses, it allows us to combine the claim that, in legal matters (like in all variable and (...) contingent subjects), we can never reach absolute certainty, with the conviction that one can nonetheless know what, with more probability, really happened.

The transmission of Greek learning to the Arabic-speaking world paved the way to the rise of Arabic philosophy. This volume offers a deep and multifarious survey of transmission of Greek philosophy through the schools of late Antiquity to the Syriac-speaking and Arabic-speaking worlds.

Partiendo del conocimiento que los árabes tuvieron de los textos neoplatónicos atribuidos a Aristóteles, tales como la Pseudo-Teología y el Liber de Causis, la autora de este estudio investiga el posible conocimiento que Avicena tuvo de este último libro, conocido en el mundo árabe por el título de Kalam fi mahd al-hayr. Se apoya, para ello, en el análisis de cuatro pasajes de la Metafísica de la gran enciclopedia filosófica Al-Sifa ("La curación").

Scholars working in the field of Graeco-Arabic Neoplatonism often discuss the role Porphyry, the editor of Plotinus, must be credited with in the formation of the Arabic Plotinian corpus. A note in this corpus apparently suggests that Porphyry provided a commentary to the so-called Theology of Aristotle, i.e., parts of some treatises of Enneads IV-VI. Consequently, Porphyry has been considered as responsible for the doctrinal shifts which affect the Arabic Plotinian paraphrase with respect to the original text. This article aims (...) at submitting this hypothesis to trial on a specific doctrinal point where Porphyry parts company with Plotinus: the relationship between the Demiurgic Intellect and World Soul. The ancient doxographical sources testify that Porphyry, in his conviction to be in agreement with Plotinus, in fact parted company with him in so far as he merged the World Soul into the Demiurgic Intellect, while Plotinus always kept them apart. There are in the Enneads some baffling passages where the role of Intellect as the Demiurge of the sensible world is not clearly distinguishable from the role of World Soul. Notwithstanding that, these passages in the Arabic paraphrase do not bear any trace of the characteristically Porphyrian merging of World Soul into Intellect.
