The naive idea of a mimesis between theory and experiments, a concept still lasing in many epistemologies, is here substituted by a more sophisticated mathematical methexis where theoretical physics is a system of production of formal structures under strong mathematical constraints, such as global and local symmetries. Instead of an ultimate “everything theory”, the image of physical theories here proposed is a totality of interconnected structures establishing the very conditions of its “thinkability” and the relations with the experimental domain.

Continuing the systematic henadological interpretation of Proclus' Platonic Theology begun in "The Intelligible Gods in the Platonic Theology of Proclus" (Methexis 21, 2008, pp. 131-143), the present article treats of the basic characteristics of intelligible-intellective (or noetico-noeric) multiplicity and its roots in henadic individuality. Intelligible-intellective multiplicity (the hypostasis of Life) is at once a universal organization of Being in its own right, and also transitional between the polycentric henadic manifold, in which each individual is immediately productive of absolute Being, (...) and the formal intellective organization, which is monocentrically and diacritically disposed. Intelligible-intellective multiplicity is generated from the dyadic relationship of henads to their power(s), the phase of henadic individuality expressed in the second intelligible triad, and is mediated, unlike the polycentric manifold, but not by identity and difference, like the intellective organization. Instead, the hypostasis of Life is constituted by ideal motility and spatiality, figural dispositions, and the intersubjective relations depicted in the divine symposium of Plato's Phaedrus.

Completing the systematic henadological interpretation of Proclus' Platonic Theology begun in "The Intelligible Gods in the Platonic Theology of Proclus" (Méthexis 21, 2008, pp. 131-143) and "The Second Intelligible Triad and the Intelligible-Intellective Gods" (Methexis 23, 2010, pp. 137-157), the present article concerns the conditions of the emergence of fully mediated, diacritical multiplicity out of the polycentric henadic manifold. The product of the activity of the intellective Gods (that is, the product of the intellective activity of Gods as such), (...) in resolving the contradiction between existential uniqueness and universalizable potencies in the divine natures, also grounds the human exercise of phi- losophical cognition in the founding self-analysis of divine individuals.

Die Beschäftigung mit Platon hat eine lange Geschichte, Rezeptionen seines Denkens sind so prägend für die Philosophiegeschichte geworden, dass diese verständlicherweise zuweilen als eine Sammlung von Fußnoten zu seinem Werk begriffen wurde. Das gilt besonders für einen durchgängigen metaphysischen Zug des abendländischen Denkens, ein grundsätzliches Ordnungsmodell aus der Antike, das, christlich gewendet, die Theoriebildung bis in unsere Tage fundiert. Aber mit einer Reihe anderer Gewissheiten ist auch dieser erfolgreiche Platonismus Gegenstand der Kritik geworden. Kann und soll man den metaphysischen Platon (...) retten oder muss man Platon vielmehr gegen die metaphysische Tradition neu verstehen? Muss man Platon gegen die Platonisten verteidigen, ist er der Anfang einer philosophischen Verirrung? -- Dorothea Frede, Ekkehard Martens, Arbogast Schmitt, Gernot Böhme, Hermann Schmitz, Wolfgang Detel und andere entdecken – auch durch ihre Kritik – Platon als Gesprächspartner der Gegenwart neu.

For Aristotle, the shape of a physical body is perceptible per se (DA II.6, 418a8-9). As I read his position, shape is thus a causal power, as a physical body can affect our sense organs simply in virtue of possessing it. But this invites a challenge. If shape is an intrinsically powerful property, and indeed an intrinsically perceptible one, then why are the objects of geometrical reasoning, as such, inert and imperceptible? I here address Aristotle’s answer to that problem, focusing (...) on the version of it that he presents in De caelo III.8. I argue that if we grant that Aristotle conceived of the shape of a sensible body as some kind of causal power, then the satisfactory resolution of that challenge pushes us to interpret him as having conceived of it as being, more specifically, an impure power—that is, as a property that is not only intrinsically powerful but also, in some way, intrinsically non-powerful as well. This is a notable result not only insofar as it illuminates Aristotle’s conception of shape but also insofar as it contributes to our knowledge of Aristotle’s theory of dunameis and his ontology more broadly.

The principle of performative contradiction. On the epistemological significance of the dialogue form in Plato's "Euthydemus". - In this study, an analysis of the section 285d-288a of Plato's "Euthydemus" shall show two things: (1) The sophistic model of a world in which there is no contradiction, in which every linguistic utterance is true and every action correct, has no semantic inconsistencies, but can only be rejected with the help of the principle of performative contradictions. (2) It is precisely these performative (...) contradictions that make it necessary for Plato to philosophize not in treatises but in dialogues; in other words, that the philosophical relevance of the Platonic form of dialogue can be seen, among other things, in the fact that - in contrast to philosophical forms of representation such as the treatise, the essay, and a henology as reconstructed and represented by the Tübingen School - it permits the representation of performative reflections and performative contradictions.

Protagoras’ Grand Speech is traditionally considered to articulate a contractualist approach to political existence and morality. There is, however, a newly emerging line of interpretation among scholars, which explores a naturalist layer in Protagoras’ ethical and political thought. This article aims to make a contribution to this new way of reading Protagoras’ speech, by discussing one of its most elaborate versions.

The present paper has two, interrelated objectives. The first is to analyze the different senses in which arguments are characterized as persuasive in the extant writings of Sextus Empiricus. The second is to examine the Pyrrhonist’s therapeutic use of arguments in the discussion with his Dogmatic rivals – more precisely, to determine the sense and basis of Sextus’ distinction between therapeutic arguments that appear weighty and therapeutic arguments that appear weak in their persuasiveness.

In disagreement with Claudia Baracchi’s controversial thesis that there is a “simultaneity and indissolubility” if not an “identity” of intelligence (nous) and perception (aisthēsis) at the core of Aristotle’s philosophy, I will argue that Aristotle maintains a fundamental distinction between these cognitive faculties. My goal in this paper is to examine specific parts of two central and complex passages, VI.8, 1142a12-30 and VI.11, 1143a33-b15, from the Nicomachean Ethics to show that Baracchi’s view is unpersuasive. I will show that Aristotle considers (...) nous to be a different capacity than mere perception and one through which particulars and indemonstrable principles become intelligible. Moreover, I will show that Aristotle considers that the objects of nous differ in kind from those that sensation (our senses) and perception (inference from our senses) grasp. After examining critically Baracchi’s thesis in light of a close reading of those two relevant passages, I will conclude the paper by showing the significance of Aristotle’s claim that a state is defined in terms of its objects of apprehension for understanding the distinction between nous and aisthēsis.

The aim of this article is to free Aristotle's Metaphysics, especially book XII (Lambda), frome some metaphysical and theological presuppositions by detecting their inappropriate conceptual framwork, which once was progressive, but now holds an obsolete position. Ousia, being (not substance, a much later concept, construed to solve other problems than Aristotle's), stand for a question, not for an answer. Book Lambda develops a highly speculative argument for this queston. The famous noesis noeseos says that empirical being and knowledge is the (...) realization of a noetic structure (noesis), laid down in our most fundamental opinioons about being. (shrink)
