Our modern scientific explanation of colour as a subjective impression has replaced a ‘pre-theoretical’ notion of colour as an intrinsic property of objects, which was mainstream in ancient thought. Why have we lost such pre-theoretical notion, and what have we lost by losing it? I argue that most ancient Greek philosophers exploited this pre-theoretical assumption – one that was obvious to them – in terms and ways that are still worthy of attention in the context of contemporary philosophy of colour. (...) I offer an in-depth analysis of the theories of a number of early Greek philosophers, as well as of Plato in the Timaeus, showing that they tend to share the idea that colour is an essential property of external bodies and therefore plays a causal role in perception. Then I focus on a comparison between Democritus’ stance and Aristotle’s in order to highlight a significant contrast between the two. Democritus' theory is an exception in ancient thought because it traces the colour phenomenon back to a refraction of atmospheric light through atomic aggregates. Aristotle, instead, posits the presence of colour and light in the bodies themselves. Finally, I interpret Aristotle's account as the most complex attempt in ancient thought to weld together what we call the ‘manifest image’ of colour and its ‘scientific image’. (shrink)

The focus of this essay is on Xenophanes’ criticism of anthropomorphic representation of the gods, famously sounding like a declaration of war against a constituent part of the Greek religion, and adopting terms and a tone that are unequalled amongst “pre-Socratic” authors for their directness and explicitness. While the main features of Xenophanes’ polemic are well known thanks to some of the most studied fragments of the pre-Socratic tradition, a different line of enquiry from the usual one is attempted by (...) considering the multi-layered background of the religious beliefs revolving around the idea that the gods have human form as outlined in the tradition of epic poetry or represented in cult statues: in the light of this consideration Xenophanes’ text can take on some new characteristics. In the second part of the article, emphasis is put on the importance of the correlation Xenophanes established between the issue of the appearance of the gods and that of the certainty of knowledge, in terms that have exerted tremendous influence on later thought, most notably on Plato in the Timaeus.

A celebrated study of the origins of ancient Greek philosophy, now in English for the first time How can we talk about the beginnings of philosophy today? How can we avoid the conventional opposition of mythology and the dawn of reason and instead explore the multiple styles of thought that emerged between them? In this acclaimed book, available in English for the first time, Maria Michela Sassi reconstructs the intellectual world of the early Greek "Presocratics" to provide a richer understanding (...) of the roots of what used to be called "the Greek miracle." The beginnings of the long process leading to philosophy were characterized by intellectual diversity and geographic polycentrism. In the sixth and fifth centuries BC, between the Asian shores of Ionia and the Greek city-states of southern Italy, thinkers started to reflect on the cosmic order, elaborate doctrines on the soul, write in solemn Homeric meter, or, later, abandon poetry for an assertive prose. And yet the Presocratics whether the Milesian natural thinkers, the rhapsode Xenophanes, the mathematician and "shaman" Pythagoras, the naturalist and seer Empedocles, the oracular Heraclitus, or the inspired Parmenides all shared an approach to critical thinking that, by questioning traditional viewpoints, revolutionized knowledge. A unique study that explores the full range of early Greek thinkers in the context of their worlds, the book also features a new introduction to the English edition in which the author discusses the latest scholarship on the subject.

L’adjectif eoikos apparaît dans trois passages cruciaux de la pensée grecque (Xénophane, fr. B35 ; Parménide, fr. B8, 60 ; Platon, Timée, 29b3-c3), caractérisant une certaine « ressemblance » à la vérité qui se veut constitutive du discours du savant. En fait, le long de cet examen on découvre que les trois usages du terme ne peuvent pas être disposés le long d’une ligne continue, vu la difficulté de comprendre à quelle notion de vérité, sous quel point de vue, et (...) avec quel degré d’évidence, ce discours se veut « ressemblant » selon l’occasion. Dans le cas de Parménide, cet aspect passe même au second plan, puisqu’on assiste à la prédominance d’une autre connotation qui accompagne le terme eoikos à partir de l’usage homérique, à savoir celle de la « convenance » à un contexte communicatif. L’article cherche dans l’ensemble à éclairer les déplacements que subit la logique de la similitude (et des procédés analogiques qui s’y greffent) en passant par des cadres ontologiques et épistémologiques aussi différents que le sont ceux de Xénophane, Parménide et Platon.

In this paper I first address what I consider a central issue in the account of perception in Plato’s Timaeus, namely, how the pathemata pass through the body to reach the soul, and thus become aistheseis. My point in Section 1 is that in tackling this issue Plato aims to provide a firm physiological basis to the notion of perception that starts to emerge in the Theaetetus and the Philebus and is crucial to the late development of his theory of (...) cognition. In the ensuing section I try to put the account of perception in the Timaeus into a historical perspective, aiming to highlight two points: a) Plato’s description of the way in which sensible impressions “travel” inside the body and interact with its parts and other constituents is largely indebted to previous theories, such as those we find, for example, in Empedocles and a few Hippocratic writers; b) The leading role in this story (where internal air plays a significant supporting role) is played by blood flowing through the vascular system and thus performing a crucial cognitive function. Moreover, emphasizing the role of blood as well as analyzing the elaborate way in which perceptions are transmitted through the body to the soul proves vital to appreciate (in Section 3) the cognitive status of the lower parts of the soul (which are more involved in perception) and their relation to reason. Overall, the paper adds further elements to our understanding of Plato’s embodied approach to cognition. I had already written (and submitted) this article when Johansen (2021) was published. The latter’s approach to the role of blood in Plato’s physiology of knowledge in the Timaeus converges in part with mine (as I was pleased to find out), partly due to our overlapping sources and bibliography.

Mon but est d’examiner en détail les arguments avancés par Vernant au début des années soixante du siècle dernier, quand il a caractérisé, selon une formule célèbre, la philosophie comme « fille de la Cité » (fille de la polis). Mon argument principal est que le concept d’isonomia, qui n’est central dans le débat politique athénien que depuis les dernières décennies du vie siècle, ne peut être aussi facilement utilisé pour rendre compte de la nouvelle conception de l’espace physique, qui (...) émerge à Milet au début de ce siècle. En tout cas, l’utilisation de modèles politiques dans la science grecque ancienne de la nature est un procédé conscient, comme je tente de le montrer en analysant certains textes célèbres comme le fragment 4 d’Alcméon et le fragment 1 d’Anaximandre. De plus, dans le cas d’Anaximandre on peut se demander si l’explanandum dans l’analogie était l’ordre du monde ou plutôt celui de la polis. (shrink)

The ideal which Plato consistently endorses and develops in the Laws is one of a city which, like the ideal soul, is perfectly at peace with its inner conflicts. The law is presented as a remedy for the destabilizing influence of the sensations and emotions which make every human being an individual, before he is a citizen. The authoritarian aspect of this remedy may worry contemporary readers, but Plato supports it with his presupposition regarding the extreme weakness of human nature. (...) In particular, the law imposes that rational regulation which each man potentially possesses within himself in so far as he is a divine creature, but which only a ‘small stock of men’ (918 c) is able to exercise. In short, the price that Plato asks us to pay for political order is the suppression of our ‘worse’, yet more human, selves. (shrink)

For this English translation, Sassi has rewritten the introduction and updated the text and references throughout, and Sir Geoffrey Lloyd has provided a new foreword.

J’aimerais commencer par une expression italienne qui décrit très bien, grâce à une assonance efficace, mes sentiments actuels, à savoir, je sens tutto l’onore e l’onere de la charge qui m’a été confiée. D’un côté, c’est évidemment un grand honneur de pouvoir présenter précisément au Centre Léon Robin mes remarques sur le nouveau recueil de textes de la tradition « présocratique » édité par André Laks et Glenn Most : et je tiens à remercier ici M. Gourinat en tant que (...) Directeur du Centre Léo... (shrink)

Cet article vise à faire ressortir les fils hétérogènes de la pensée sur les émotions qui traversent la littérature philosophique et médicale grecque des cinquième et quatrième siècles avant J.‑C., contribuant à l’émergence de la sphère des passions en tant que territoire autonome pour l’exploration des faits mentaux. Nous examinons d’abord le modèle psychologique homérique dans le but de mettre en évidence son influence sur la littérature philosophique et non philosophique grecque des siècles suivants. Les auteurs hippocratiques, en particulier, se (...) révèlent redevables du monisme «materialiste» d’Homère, mais on retrouve également des traces du modèle épique chez les penseurs qui, par la suite, se sont intéressés à la relation entre le corps et l’entité‑âme. Nous reconstituons ensuite l’évolution au cours de laquelle, d’Héraclite à Démocrite, de Platon à Aristote et au Péripatos, une notion du pathos en tant qu’emotion finit par émerger, prête à être acceptée et bien sûr précisée autant que retravaillée par les philosophies des âges hellénistique et romain.

Cet ouvrage vigoureux, fruit d’une longue recherche que Christopher Moore a menée au cours des dix dernières années, propose une perspective nouvelle et stimulante sur les origines de la philosophie grecque. Plus précisément, comme l’explique Moore dans le premier chapitre introductif (p. 1-33), il ne s’est pas fixé pour objectif de reconstituer (la nième fois) le déroulement des doctrines des penseurs grecs à partir de Thalès, mais d’enquêter sur les significations prises par le terme philos...

This essay provides a comprehensive and detailed analysis of a cluster of Heraclitus’ fragments that revolve around an image of ‘musical’ harmony (B 8, 10, and 51 Diels-Kranz). The aim is to demonstrate that more numerous as well as more specific references to contemporary musical practice can be found in these fragments than is usually thought. In particular, it is argued that in his talk of cosmic harmonia Heraclitus might well know and exploit a musical sense of this word, namely, (...) that of ‘attunement’, which was already developing at his time from the primary meaning of ‘connection’ and ‘agreement’. Furthermore, it is shown that the investigation of musical patterns with which Heraclitus was clearly acquainted offered him a significant analogical ground for his reflection on the order and rationality of kosmos. He was not apparently interested in the numerical definition of musical patterns, and thus there is no need to assume any influence of earlier Pythagorean research on his theory of cosmic harmony: the other way round, this theory was likely food for thought for Philolaus.

This paper analyses chapter 58 of Theophrastus’ De sensibus, where Democritus’ account of phronein is famously presented. Democritus traces phronein to symmetria of the soul, that is conceived, in turn, as a state of thermic equilibrium, depending on his consideration of psyche as an aggregate of spherical and thin atoms flowing throughout the body and giving it life, movement, and perception. As a consequence, according to him, psychic states go hand in hand with changes in the body. In the following (...) section of this paper, I offer additional evidence in favor of the controversial manuscript reading μετὰ τὴν κίνησιν. As a result, a consistent theory by Democritus can be reconstructed, according to which the balanced state of mobility and temperature of the psychic atoms concentrated in the head that generates a correct thinking necessarily follows the movement of sensible eidola throughout the body. In fact, a number of passages from Hippocratic writings attest that Democritus shared the key features of this explanation with the physiological and medical approach of the time. (shrink)

J’essaie d’explorer la vision religieuse d’Euripide en le considérant comme un penseur en même temps qu’un artiste, ou mieux, comme un auteur qui soulève en artiste des questions essentielles sur le sens de l’existence humaine par rapport à celle des dieux, non pas tellement en mettant dans la bouche de ses personnages certaines doxai, mais plutôt en les faisant parler et agir d’une certaine façon dans une situation dramatique particulière. En me détachant aussi bien des savants qui ont vu dans (...) Euripide un défenseur de la tradition religieuse, que de ceux qui ont tendance à déconstruire ses figures des dieux dans un jeu de projections de la psychologie humaine, je soutiens qu’Euripide a mis en question dès le début la consistance des croyances traditionnelles, avec une inquiétude grandissante qui a abouti, sinon à une négation de l’existence des dieux, du moins à une attitude exaspérée de doute sur leur rôle dans l’existence humaine : ce qui est suffisant pour qu’il puisse être compté parmi les auteurs que Platon accuse d’impiété dans le livre X des Lois.

L’arte della memoria è uno degli archetipi della cultura occidentale fin dall’antica Grecia: è stato Platone ad ‘inventare’ l’immagine dell’anima come blocco di cera, su cui le sensazioni si imprimono come segni di sigilli; ed è stato poi Aristotele a riprendere in parte questo modello, arricchendolo però di temi fondamentali. Ma anche in epoche successive l’arte della memoria ha svolto una funzione fondamentale intrecciandosi a temi sia epistemologici che di schietta natura metafisica. Questo volume, frutto di un seminario tenuto alla (...) Scuola Normale nel settembre 2006, intende ripercorrere alcune delle principali stazioni della riflessione sulla memoria fra antichità e mondo moderno chiedendosi se, e in quale misura, questa relativa continuità di approccio si debba ad un consapevole attingere alla tradizione platonica e aristotelica; se, e in quale misura, elementi comuni o varianti del modello iniziale siano riportabili alle metafore adottate, sin da subito, per la descrizione dei processi mentali – riconducibili in ogni caso all’idea comune di ‘tracce’ che la sensazione imprime nell’anima.
