The author tries to expose the reception of Aristotelian philosophy among the first Greek Churchfathers, from St. Justin to the 'Refutatio'. There are some interesting points concerning the doxographical tradition, specially relating to the Aristotelian idea of God.

> καὶ πῶς τις ἀνάξει αὐτοὺς εἰς φῶς, ὥσπερ > > ἐξ Ἅιδου λέγονται δή τινες εἰς θεοὺς ἀνελθεῖν; > > Plato Republic 521c This study reconstructs Empedocles’ eschatology and cosmology, arguing that they presuppose one another. Part one surveys body and soul in Empedocles and argues that the transmigrating daimon is a long-lived compound made of the elements air and fire. Part two shows that Empedocles situates our current life in Hades, then considers the testimonies concerning different cosmic levels (...) in Empedocles and compares them with the afterlife schemes in Pindar’s Second Olympian Ode and Plato’s Phaedo myth. Part three offers a new edition of section d lines 5–10 of the Strasbourg papyrus of Empedocles that reinforces the connection between transmigration and different cosmic locations for souls. Part four reconstructs Empedocles’ cosmology, identifies three different levels or habitats of soul, and, more tentatively, suggests that Empedoclean “long-lived gods” are best understood as stars.

In this paper I propose a reading of Plotinus Enneads VI.1-3 [41-43] On the genera of being which regards this treatise as a coherent whole in which Aristotle's Categories is explored in a way that turns it into a decisive contribution to Plotinus' Platonic ontology. In addition, I claim that Porphyry's Isagoge and commentaries on the Categories start by adopting Plotinus' point of view, including his notion of genus, and proceed by explaining its consequences for a more detailed reading of (...) the Categories. After Plotinus' integration of the Categories into the Platonic frame of thought Porphyry saw the possibilities of exploiting the Peripatetic tradition both as a means to support the Platonic interpretation of the Categories and as a source for solutions to traditional questions. His allegiance to a division of being into ten, and his emphasis on semantics rather than ontology can be explained from this orientation. In the light of our investigation the alleged disagreement between Plotinus and Porphyry on the Categories changes its appearance completely. There are differences, but these can be best explained as confirmation and extension of Plotinus' perspective on the Categories and its role in Platonism. (shrink)

This paper presents an analysis of Seneca's 58th letter to Lucilius and Porphyry's Isagoge, which were the origin of the tree diagrams that became popular in philosophy and logic from the early Middle Ages onwards. These diagrams visualise the extent to which a concept can be understood as a category, genus, species or individual and what the method of dihairesis (division) means. The paper explores the dissimilarities between Seneca's and Porphyry's tree structures, scrutinising them through the perspective of modern graph (...) theory. Although traditional trees can be interpreted in a modern way, their terms and definitions defy modern standardisation. These distinctions are not only useful for differentiating between Seneca's and Porphyry's trees, but also for comprehending the evolution of this philosophical tradition. Thus the paper highlights the continued significance of these tree diagrams in analysing concepts and categories in philosophy and structuring objects and information in modern fields such as artificial intelligence, computer science, bioinformatics, graph theory, and many more.

Drawing on recent scholarship and delving systematically into Iamblichean texts, these ten papers establish Iamblichus as the great innovator of Neoplatonic philosophy who broadened its appeal for future generations of philosophers.

Our purpose on the present occasion is to evaluate some ideas the biographers of late antiquity held about the origins of European thought. Speaking about this period we are no longer dealing with the question of transferring of the archaic practices: these practices are indeed long dead. What we encounter can be better defined as the import of ideas. Equally important is a study of the changing attitudes of our authors: rather than passive witnesses, they became active participants of this (...) import. The process is truly fascinating and we hope that the following examples, mostly from Hippolytus, will elucidate this. The best, almost a paradigmatic example is Pythagoras, who in late antiquity had many faces. His biography is an interesting instance of general change of attitude to ancient wisdom, typical for the source utilized by Hippolytus. Looking at a number of peculiar features of Hippolytus’ report which, we hope, will help us to see why the image of Pythagoras and his philosophy, formed by Hippolytus, is somewhat untypical for the period. We will see that Hippolytus’ biographic report, however garbled, shows no signs of so-called ‘Neopythagorean’ biographic development. Admittedly, the later authors frequently combine their sources to make them suitable to their needs, polemical or apologetic. Do we still have a reason to believe that these stories, however doubtful from the historical point of view, may contain the germs of truth? (shrink)

In several iterations of the Gnostic ontogenetic myth, we find variations on an intriguing notion: namely, that the first rupture in the otherwise eternal and continuous procession of ‘aeons’ in the divine ‘pleroma’ is caused by a cognitive overreach and failure (the “fall of Sophia”). As much as it might contain a distant echo of certain myths concerning hubris in the classical tradition or in biblical literature, this general schema of cognitive overreach—cognitive failure—fall has no obvious parallel in Greek philosophy (...) prior to Plotinus, in some of whose more pessimistic accounts of hypostatic procession we find a similar schema, in which the generation of each ontological stratum occurs as the result of a cognitive failure on the superjacent level. If Plotinus borrowed this schema from the Gnostics, one might ask how the latter came up with it in the first place. In response, this paper makes the following three points. [1] Gnostic thinkers ultimately derived this schema from a particular juxtaposition of two profoundly aporetic Platonic passages referring to the travails of the individual soul, one certainly genuine (the description of the unexplained but catastrophic fall of the soul that fails to follow the heavenly train of the gods through the intelligible realm at Phaedrus 248c2-d3), the other quite possibly spurious (the claim that the cause of all evils is the desire, and the failure, of the soul to understand the nature of the notoriously enigmatic ‘King,’ ‘Second,’ and ‘Third,’ at 2nd Letter 312e1-313a6). [2] The Platonizing Sethian Gnostics closest to Plotinus also employed this latter source text to justify their conception of the individual soul, whose vicissitudes were understood to parallel those of Sophia. [3] This hypothesis is confirmed by evidence of tacit anti-Gnostic argumentation alluding to the 2nd Letter throughout Plotinus’ oeuvre. (shrink)

One of the aims of the Neoplatonists is to demonstrate that ancient Presocratic thought is, in fact, a Preplatonic thought. According to the Neoplatonists, Presocratics, who were not far from the truth, employed an inaccurate and ambiguous language, whereas Plato spoke about the truth in a more appropriate and clear way. That is why the Presocratics are not necessarily erroneous and their theoretical originality and their terminology can be incorporated into the Neoplatonic philosophy. I would like to show how some (...) Presocratic theories are embedded in the Neoplatonic metaphysical system of the three Hypostases. Regarding the One and the Intellect, Plotinus, Proclus and the Anonymous Author of the Prolegomena to Platonic Philosophy read and employ some Presocratic texts in order to harmonize the Platonic and the Presocratic accounts. Although the Neoplatonists see themselves as continuing the Greek philosophical tradition started by the Presocratics, their interpretation of Presocratic thought illustrates the birth of exegetic philosophy which is able to apply ancient concepts and predicates to its own metaphysical theory.

Sextus’ interpretation of Xenophanes’ scepticism in M 7.49–52 is often cited but has never been subject to detailed analysis. Such analysis reveals that Sextus’ interpretation raises far more complex problems than has been recognised. Scholars invariably assume one of two ways of construing his account of Xenophanes B34, without observing that the choice between these two alternatives poses an interpretive dilemma. Some scholars take it that Sextus ascribes to Xenophanes the view that one may have knowledge without knowing that one (...) has knowledge. Others take it that he ascribes to Xenophanes the view that one may have true belief without knowing that one has true belief. A close examination of Sextus’ paraphrase exposes a crucial but overlooked complication. Sextus elides Xenophanes’ pivotal distinction between knowing “the clear and certain” and believing “what has been fulfilled” . He eliminates altogether tetelesmenon from his analysis of B34, and expands the role of to saphes. I demonstrate that, as a result, Xenophanes B34, as interpreted by Sextus, does not consistently and straightforwardly express either view or view . Sextus, I argue, in fact develops a fundamentally incoherent interpretation of Xenophanes B34. On Sextus’ interpretation, Xenophanes justifies the proposition “No human knows” by arguing that, even if a human does, in fact, know, he does not know that he knows. Finally, I argue that Sextus’ incoherent account reflects not unthinking negligence, but a sophisticated if ultimately doomed attempt to interpret the logical structure of Xenophanes B34 in line with later models of second-order scepticism.

Eugene Afonasin highlights the wealth of information on Pythagoras and his tradition preserved in Clement of Alexandria’s Stromateis and presents them against the background of Later Platonic philosophy. He  rst outlines what Clement knew about the Pythagoreans, and then what he made of the Pythagorean ideal and how he reinterpreted it for his own purposes. Clement clearly occupies an intermediate position between the Neopythagorean biographical tradition, rmly based on Nicomachus, and that more or less vague and difuse literary situation (...) which preceded the later developments, and in this respect is a very good source, worth studying for its own sake and as supplementary material which can help to understand the great Pythagorean synthesis attempted by Iamblichus. Developing their variants of the “exhortation to philosophy” (protreptikoi logoi), these men were much concerned with the educational value of the Pythagorean way of life rather than biographical circumstances, designed to place the ancient sage in the proper cultural context.

Although Presocratics in 600 B.C founded new research ways in science and philosophy, wrote the first scientific essays, introduced basic conceptions of deduction, and abandoned mythological explanations, all we have of their works is but the fragments in the works of further doxographers, biographers, historians or philosophers who brought their statements between their own words. This would sometimes result in misunderstanding the presocratics’ purposes. Hermann Diels in his Doxographi Graeci raised a new method for dealing with doxography tradition. Diels’ new (...) approach to doxography returned all this tradition to Aristotle’s pupil, Theophrastus. Some scholars like Jaap Mansfield criticized his disregard for the sophists like Gorgias and Hippias, and the successions of philosophers. According to his criticism, some matters like the Sophists’ influence on Plato, Aristotle’s definition of Doxa in the Placita and the influence of the succession and interpretation tradition on doxogtaphy are more noteworthy than Diels has thought.
