Our «universal» perception of Parmenides’ poem is biased by traditional readings to a considerable degree, at least if the poem actually included two different doctrinal bodies, one on being and another peri physeōs properly, the latter encompassing a number of short treatises on the physical world and (some) living organisms.What I plan to offer in support of this claim is, to begin with, an inventory (the first ever prepared) of the topics dealt with in the section devoted to physical world and living creatures (§ 2). Something on Parmenides’ way of studying and understanding different aspects of the physical world and living organisms follows (§ 3).Once acknowledged the above (a point which is not particularly controversial, I presume), the poem comes to look quite differently and some principles of interpretation are likely to collapse : first of all, the customary assumption that frgs. 1‑9 include definite ideas on the doctrines to be found in the second main body, and tell us that they are not of great value. Indeed, the very high quality of several among these doctrines seems to imply that no devaluation of the second main doctrinal body is tenable.Several corollaries are likely to follow. Among them : (a) once concluded the section on being, no further group of verses, meant to establish a convenient relation between the first and the second main doctrinal body, surfaces ; (b) Parmenides was a polymath, and he may have been aware of that, or at least some evidence in support of the awareness thesis is available.

The article is dedicated to the study of the origins of Christian cosmogony. Christian authors of the 2nd century are known for their enigmatic or ambiguous positions on the issue. The problem concerns mainly the apologists, but it first appears in Ignatius of Antioch (†180) and continues in Bardesanes (†222). Although they all confess God as the Creator, their ways of presenting the act of creation are strongly marked by philosophical doctrines, primarily by Platonism, or by Stoicism in the case of Bardesanes. The Christian Creator receives the characteristics of a demiurge and an artisan. This approach has implications for the notions of universe and matter. But first and foremost, the idea of God as a demiurge and an artisan determines the role assigned to the Logos in the act of creation. Those concepts are later abandoned in favour of a doctrine based more on the Bible, but they give us a better understanding of the relationship between young Christianity and Platonism.

La discussione sull’idea del buono (to agathon) occupa uno spazio marginale nel libro VI della Repubblica, ma comporta un eccezionale impegno teorico : di qui la vastita della letteratura esegetica che contrasta con la brevita del testo platonico. Il problema cruciale e questo : in Repubblica VI 504a‑509c to agathon non e piu solo un principio di valorizzazione e un criterio di valutazione di cose e condotte – com’e consueto in Platone – ma assume il ruolo di principio ontologico ed epistemologico. Questa posizione ha spesso suggerito interpretazioni di tipo “teologico” dell’idea del buono (identificata a volte con l’Uno neoplatonico, altre con il Demiurgo del Timeo). Quello che si puo affermare sulla base del testo, e che Platone ha conferito in queste pagine della Repubblica un primato al vertice etico del triangolo i cui altri vertici sono quello ontologico e quello epistemologico ; l’intento e quello di offrire una fondazione etica assoluta (antiprotagorea), mediante la connessione della sfera del valore con quelle dell’essere e della verita (quindi anche in ambito politico una giustificazione ultimativa al diritto dei filosofi a governare).L’unificazione delle dimensioni etica, ontologica ed epistemologica sarebbe parsa teoricamente insostenibile ad Aristotele, cui si deve una critica devastante alla teoria platonica del buono.

The article again treats the question of whether ≪the Idea of the Good is a Reality in the Universe, or beyond it. Is it immanent or transcendent ?≫ (Rufus Jones, 1863‑1948). Plato scholars such as Matthias Baltes (1940‑2003) and Luc Brisson have defended the thesis that Plato’s Idea of the Good is, on the one hand, beyond being (epekeina tes ousias) in dignity and power, but, on the other, is nevertheless not transcendent over being. The article delivers first (I) the most important arguments for the thesis of Baltes and Brisson. Then (II), it gives two counterarguments against the thesis. Third (III), it concludes with some general questions concerning the deflationist interpretation of Plato’s Republic 509b9‑10, and defends again the transcendence of the Idea of the Good.

Un debat tres vif eut lieu parmi les commentateurs medioplatoniciens sur le rapport entre la forme du bien de la Republique et le demiurge du Timee. Certains d’entre eux, comme Plutarque et Atticus, parvinrent a identifier ces deux entites, d’autres, comme Numenius, a situer les deux principes dans une relation hierarchique, en attribuant au bien la qualification de ≪premier dieu≫ et de pere (pater) et au demiurge celle de ≪second dieu≫ et de producteur (poietes). Cet article se propose d’examiner la question de l’identite de la forme du bien avec le demiurge sur des bases nouvelles, en prenant comme point de depart une interpretation metaphorique de la figure du demiurge, qui ne se presente pas comme un principe metaphysique independant, mais comme une description metaphorique de l’element causal‑efficient du monde des formes, c’est a dire du vivant intelligible. Le demiurge coinciderait donc avec la totalite active et dynamique du monde intelligible (panteles zoon). Dans la seconde partie de l’article est prise en consideration l’hypothese que la superiorite de la forme du bien par rapport aux autres formes est du meme genre que celle du demiurge, dans la mesure ou le bien aussi peut etre compris comme la totalite du kosmos intelligible. Il s’agit d’une hypothese qui ne va pas sans difficultes, mais qui merite d’etre examinee jusqu’au bout.

Self‑sufficiency of the Good and dependency of Being ? From Republic to Sophist. Even thought Parmenides doesn’t use αὐτάρκης and any noun derived from this root, the Being is conceived by him as self‑sufficient (v. 8,33). Plato, for its part, never uses this term concerning the intelligible reality ; however, in the Sophist, he allusively challenges Parmenides self‑sufficiency of Being and outlines an ontology that is conflicting with it. On the other hand self‑sufficiency is explicitly ascribed by Plato to the human good (Philebus, 20d, 67a), to the divine world (Timaeus, 33d), and also to the virtuous man (Republic, 387d). This paper aims to demonstrate that these facets (theological or anthropological) of self‑sufficiency are consistent with the supremacy of the idea of the Good in the Republic, which can be understood as a structural kind of self‑sufficiency.

Among Plato’s dialogues, the Timaeus was the most authoritative for Middle Platonists. But alone it does not suffice to explain some of the most important tenets defended by these philosophers. A remarkable example is the doctrine of the three Principles (God, Ideas, matter), which characterizes imperial Platonism, and which cannot be stated on the basis of the Timaeus alone. In my paper I show that Numenius was influenced by the Republic as well : in the metaphor of the Sun he found the Good as first principle and an indication of a second principle which is further subdivided into an Intellect thinking the Ideas and a Demiurge ordering the universe. This interpretation provides him with some interesting solutions. But such an influence also raises difficulties insofar as the causal role of the first principle is concerned.

Why does the Stoic demiurge cause the conflagration ? In this paper, I revisit some issues addressed in Salles 2005 and argue that the conflagration is the result of an incapacity in the demiurge for creating an everlasting and uninterrupted cosmic order. Also, I bring out in more detail (a) the parallel between the Stoics and Plato at Tim. 75a‑c (section 1), (b) why cosmic order is the ultimate end pursued by the demiurge (section 2), (c) what is the physical mechanism that leads up to the conflagration (section 3), and (d) why the conflagration is contrary to the cosmic order (sections 1 and 4).

Il y a chez Philon des expressions pour parler du bien qui sont apparemment contradictoires ou qui, au moins, font difficulte. Dans quelques passages l’Alexandrin parle de Dieu en termes de bien ; ailleurs il en parle comme de cause ou source du bien ; dans autres textes, enfin, Dieu est meilleur que le bien.Le theme de la possibilite de connaitre Dieu aussi pose des problemes : d’un cote nous avons le Dieu inconnaissable dont meme pas le nom ne peut etre dit, d’un autre, le Dieu demiurgique et providentiel dont quelques personnages parviennent a avoir une connaissance, au moins indirecte et partielle. Telle vision est proportionnelle au niveau du voyant. Cet article s’interroge a propos d’une solution similaire concernant la perception du bien, saisi par les hommes de facon differente selon leur niveau. Non pas, alors, Dieu comme bien, comme bon, comme meilleur que le bien, per se, mais en relation aux hommes qui n’arrivent pas a atteindre to agathon et cherchent vainement a lui attribuer un nom – quoique impropre –, de determiner ce qui est au dela de toute nomination, qualification, definition.

Mauro Bonazzi has shown how Numenius based his theology on his interpretation of Plato’s Timaios and Politeia. However, by giving the title On the Good (Περὶ τἀγαθοῦ) to his own dialogue, Numenius inserts it in the line of the teaching that, according to the tradition, Plato would have orally given on this topic. After focusing briefly on this teaching and its problems, the paper examines how Numenius appropriated it, as it reached him. It will appear that Numenius conceives of the oral tradition as the Pythagorean core of Plato’s teaching, a core that, according to him, its transmitters did not understand properly, and that he claims to find himself in a good interpretation of that which he has direct access to : the writings of the Master.

The anecdote recounted by Aristoxenus, who claims to be reporting Aristotle’s words, has been used by several interpreters to maintain the existence of a doctrine of the Good reserved for the members of the Academy, and transmitted orally, after the model of Pythagorean teaching. Yet a close analysis of these few lines shows that this interpretation has no basis : instead, what is at issue is a reading, for a broad audience, of a text corresponding to a doctrine of the good that can be found in the Republic and the Laws.
