This article expands a traditional pedagogic interpretation of Plato’s reasons for urging trainee rulers to study astronomy. It argues, primarily, that they need to become familiar with astronomy because it teaches them about cosmic harmony. This harmony indeed models a “personal harmony,” which will prevent them from becoming tyrants, and informs them about the analogous social harmony— which it will be their special duty to create and maintain. In Plato’s view, indeed, astronomy shows that social harmony requires obedience on the (...) part of the lower orders and that social goods are best distributed in accordance with a special antidemocratic principle of equality.

In the analysis of Anaxagoras’ physics in view of the relation between his teachings on multitude and heterogeneity, two central questions emerge: 1) How can the structure of the universe considered purely mereo-topologically help us explain that at the first cosmic stage no qualitative difference is manifest in spite of the fact that the entire qualitative heterogeneity is supposedly already present there? 2) How can heterogeneity become manifest at the second stage, resulting from the noûs intervention, if according to fragment (...) B 6 such a possibility requires the existence of “the smallest”, while according to the general principle stated in fragment B 3 there is not “the smallest” but always only “a smaller”? This paper showcases the perplexity of these two questions but deals only with the former. The answer follows from Anaxagoras’ being a thoroughgoing infinitist in the way in which no Greek physicist was: the principle of space isotropy operative in geometry is extended to physics as well. So any two parts of the original mixture are similar to each other not only in view of the smaller-larger relation but also because each contains everything that the other one contains. This in effect means that at the stage of maximal possible heterogeneity each part of any part contains infinitely many heterogeneous parts of any kind whatsoever. So, neither can there be homogeneous parts in view of any qualitative property, nor can there be predominance in quantity of parts of any kind that would make some property manifest. (shrink)

Xenophanes of Colophon was a philosophically-minded poet who lived in various parts of the ancient Greek world during the late 6th and early 5th centuries BC. He is best remembered for a novel critique of anthropomorphism in religion, a partial advance toward monotheism, and some pioneering reflections on the conditions of knowledge. Many later writers, perhaps influenced by two brief characterizations of Xenophanes by Plato (Sophist 242c-d) and Aristotle (Metaphysics 986b18-27) identified him as the founder of Eleatic philosophy (the view (...) that despite appearances, what there is is a changeless, motionless, and eternal ‘one’. In fact, the Xenophanes who emerges from the surviving fragments defies simple classification. He was a traveling rhapsode who criticized the stories about the gods told by the poets, and he defended a novel conception of the divine nature. But he was also a reflective observer of the human condition, a practitioner of the special form of inquiry introduced by the Milesians philosopher-scientists, and a civic counselor who encouraged his fellow citizens to respect the gods and work to safeguard the well-being of their city.

The problem of explaining color perception has fascinated painters, philosophers and scientists throughout the history. In many cases, the ideas and discoveries about color perception in one of these categories influenced the others, thus resulting in one of the most remarkable cross-fertilization of human thought. At the end of the nineteenth century, two models stood out as the most convincing ones: Young-Helmholtz’s trichromacy on one side, and Hering’s opponency on the other side. The former was mainly supported by painters and (...) scientists, although with some noticeable exceptions as, e.g., Otto Runge, while the majority of philosophers supported the latter. These two apparently incompatible models were proven to be two complementary parts of the hugely complex chain of events which leads to human color perception. Recently, a rigorous mathematical theory able to incorporate both trichromacy and opponency has been developed thanks to the use of the language and tools of quantum information. In this paper, we discuss the placement of this model within the philosophical theories about color. (shrink)

The paper explores the interrelations between Pindar, Heraclitus and the Hippocratic author with regard to ideas of the body, the soul and dreams. I shall consider Pindar’s fr.131b as an overlooked testimony of the poet’s interest in a non-Homeric conceptualization of the soul. I will suggest reading Heraclitus’ fragments B26 and B21 together and offer a new interpretation of the latter. Furthermore, I will compare Pindar’s fr. 131b with the HippocraticOn Regimen(4. 86, 87) and Pindar’s fr. 133 withOn Regimen(4. 92) (...) respectively, in order to highlight unnoticed similarities.

The relationship between conceptions of law and conceptions of nature is a complex one, and proceeds on what appear to be two distinct fronts. On the one hand, we frequently talk of nature as being lawlike or as obeying laws. On the other hand there are schools of philosophy that seek to justify ethics generally, or legal theory specifically, in conceptions of nature. Questions about the historical origins and development of claims that nature is lawlike are generally treated as entirely (...) distinct from the development of ethical natural law theories. By looking at the many intersections of law and nature in antiquity, this paper shows that such a sharp distinction is overly simplistic, and often relies crucially on the imposition of an artificial and anachronistic suppression of the role of gods or divinity in the worlds of ancient natural philosophy. Furthermore, by tightening up the terms of the debate, we see that the common claim that a conception of ‘laws of nature’ only emerges in the Scientific Revolution is built on a superficial reading of the ancient evidence.Keywords: Ancient science; Philosophy of science; Philosophy of law; Ancient theology; Scientific Revolution.

Anaxagoras of Clazomenae (a major Greek city of Ionian Asia Minor), a Greek philosopher of the 5th century B.C.E. (born ca. 500–480), was the first of the Presocratic philosophers to live in Athens. He propounded a physical theory of “everything-in-everything,” and claimed that nous (intellect or mind) was the motive cause of the cosmos. He was the first to give a correct explanation of eclipses, and was both famous and notorious for his scientific theories, including the claims that the sun (...) is a mass of red-hot metal, that the moon is earthy, and that the stars are fiery stones. Anaxagoras maintained that the original state of the cosmos was a mixture of all its ingredients (the basic realities of his system). The ingredients are thoroughly mixed, so that no individual ingredient as such is evident, but the mixture is not entirely uniform or homogeneous. (shrink)

Przedmiotem artykułu są teorie pierwszych ontologów greckich: Ksenofanesa, Parmenidesa i Melissosa na temat bytu, jego jedności i tożsamości, z uwzględnieniem niektórych poglądów Zenona. Naczelnym problemem artykułu jest pytanie o naturę relacji bytu względem świata u filozofów eleackich. Celem jest opis sposobu rozumienia tego powiązania, zaproponowanego przez każdego z nich. W rezultacie analiz porównawczych, opierając się na badaniu zachowanych fragmentów tekstów starożytnych, okazało się, że Ksenofanes jest autorem koncepcji Jedno-Boga tożsamego ze światem, zaś Parmenides sformułował oryginalną teorię bytu transcendującego świat cielesny, (...) ale stanowiącego jego rację tożsamości jako całości. Przedstawiona w artykule interpretacja poglądów Parmenidesa stanowi ujęcie odmienne od powszechnie przyjmowanego. Melissos natomiast wykorzystując Parmenidejski sposób rozumienia bytu jako czegoś jednego umieszcza go w świecie. Zbliża to poglądy Melissosa do poglądów Ksenofanesa. Każda z tych teorii nastręcza jednak wielu problemów interpretacyjnych, wynikających przede wszystkim z niewielkiej ilości tekstów źródłowych. ------------------------- Zgłoszono: 06/11/2022.

Empedocles’ B100 contains an analogy between a girl handling a clepsydra and respiration. This article argues that proposals to establish Love or Persephone as the girl’s respiratory equivalent are rendered unlikely by differences between their respective causal roles. Rather than her gender, this article emphasises the importance of the girl’s age: Empedocles required a playful child to handle the clepsydra. This child’s play results in the extra phase of submerging the clepsydra while the upper vent is open, which Empedocles needed (...) to form a parallel for the first static phase of respiration.

For several decades, scholars of Plato's dialogues have focussed their efforts on understanding Socrates’ philosophy by unravelling the arguments used to establish it. On this view, Socrates’ philosophy is presented in his arguments, and, as Gregory Vlastos says, ‘Almost everything Socrates says is wiry argument; that is the beauty of his talk for a philosopher.’ In this paper I raise questions about what can be learned about Socrates’ philosophy through analysis of his arguments. One critic of what he views as (...) traditional interpretations of Plato—‘the sole frame of reference used by most interpreters of Plato from antiquity to the present’—describes this approach as follows: reading the dialogues to discover Platonic or Socratic doctrines, andthe logic of the arguments on which these doctrines are based.While I subscribe to the first point, I have questions about, the ready contention that Plato's dogmas are based on the arguments through which they are defended in dialogues.

The paper provides an innovative interpretation of the treatise De Victu, showing that, though Heraclitean, Anaxagorean and Empedoclean borrowings in the work are certainly pervasive, the author also develops a sophisticated and multi-purpose explanatory framework, which, being based on an original conception of the nature of man, the cosmos and the relationship between the two, provides an effective foundation for the medical enterprise, allowing him to propose his dietetics as a ‘way of life’. At the core of this enterprise is (...) the relationship between microcosm and macrocosm: in virtue of this relationship, I submit, the cosmos becomes both an active factor to be taken into account for the maintenance of individual physical well-being and the normative standard to which a dietician and whoever cares about health must refer in order to live the healthiest possible life.

In two of his dialogues especially, the Sophist and the Parmenides, Plato concerns himself at length with problems presented by the Eleatics. Despite difficulties in the interpretation of individual passages, the Sophist has in general proved the less difficult to understand, and since some of the problems at issue in the two works indicate the same or similar preoccupations in Plato's mind, it is worth considering how far an interpretation of the ‘easier’ dialogue can be used to forward an interpretation (...) of the more difficult. First, therefore, we must identify problems common to the two works; then we must see whether we can understand what Plato understood Parmenides to have done—this may help towards an understanding of what he did in fact do; finally we can apply our findings to the Parmenides itself, particularly to the problem of the unity of the dialogue, in the hope that Plato's intentions may become clearer.

ABSTRACT: Careful analysis of the details of the text allows us to refine Socrates objections to his definition of manliness as prudent perseverance. He does not appreciate that Socrates objections merely require that he make his definition more precise. Nicias refuses to consider objections to his understanding of manliness as avoiding actions that entail risk. The two sets of objections show that manliness entails first calculating that a risk is worth taking and then subsequently not rejecting that calculation without due (...) consideration. (shrink)

The three processes needed to create life, compartmentalization, metabolism, and information transfer (memory stored in nucleic acids and manipulation operated by proteins) are embedded in organized genome features. The core of life puts together growth and maintenance (which drives survival), while life in context explores and exploits specific niches. Analysis of gene persistence in a large number of genomes shows that the former constitutes the paleome, which recapitulates the three phases of the origin of life: metabolism of small molecules on (...) surfaces, substitution of surfaces by an RNA-world where transfer RNA played a central role, and invention of template mediated information transfer. Colonization of each niche is performed using an almost unlimited set of genes, forming the cenome. The agreement of the paleome structure with a consistent scenario for the origin of life is such that we may consider extant genomes as providing us with an archive of the origin rather than as a palimpsest where most of our past would be irremediably hidden.

This paper attempts to determine what laws’ most fundamental normative property is for Plato. After examining the Hippias Major and the pseudo-Platonic Minos, I argue that in the Laws this property is correctness (orthotês) which is understood as maximizing the citizens’ happiness. I argue that laws failing to do so are defective as laws because they’re not partially grounded in the relevant ethical facts and that Plato is thus a natural law theorist. The last section provides further justification for the (...) claim that laws failing the correctness criterion are defective as laws by appealing to Plato’s understanding of practical rationality.

Aristotle presented an influential conception of the universe consisting of a sphere of fixed stars with a spherical Earth at its centre. A spherical conception of heaven and Earth appears also in Plato’s writings. In presocratic cosmology, the idea of a spherical universe appears probably first in the thoughts of the Pythagoreans and Parmenides. But while there is no surviving evidence for the cosmology of early Pythagoreans, various sources mention in relation to Parmenides a solid surrounding part and a spherical (...) Earth at the centre of the universe. Being, which Parmenides had likened to a sphere, may have moreover in a cosmological sense referred to ‘heaven.’ Furthermore, we can observe in presocratic cosmologies a development which shows that the cosmology of heavenly sphere appeared in the fifth century BCE. Although Parmenides is commonly thought to have influenced especially ontology, one can argue that it was he who introduced the concept of a heavenly sphere to cosmology, a notion which in Aristotle’s thought evolved into the notion of a sphere of fixed stars forming the boundary of the world.

This essay argues that although political thinkers frequently draw on his thought, Friedrich Nietzsche has not been read as a ‘thinker of politics’ in his own regard because the Euro-American field of political thought owes its very notion of ‘politics’ to the conceptual heritage Nietzsche's project directly challenges. The first part of the essay traces the prevailing conception of politics to Aristotle, in whose view politics is the quintessentially human ( anthropos) activity of organising collective life through reason/speech ( logos). (...) The second part presents Nietzsche's project as a novel type of political naturalism, one which replaces the two Aristotelian axioms underpinning standard construals of politics, namely logocentrism and anthropocentrism. For Nietzsche, politics is not a unique, intra-species behaviour of certain bipedal primates, but the relational power dynamics present in all of nature, humans included. Nietzsche's political naturalism thereby gifts us an image of politics befitting the thoroughly entangled, volatile world we urgently have to come to terms with today. (shrink)

Both Hippolytus of Rome and Sextus Empiricus attribute a concept of λόγος to Empedocles, relying on fragments that seem to have nothing to do with this claim. This article aims to show how the identification and clarification of their common Stoic source helps us to understand these texts better, and to reconstruct an interpretation of Empedocles’ epistemology that has not attracted critical attention so far.

Some determinist approaches to free will opine that the human brain is subordinate to physical laws not fully under our control. This results in a weakening of the concept of the personal autonomy and moral responsibility of humans. Were we to acknowledge this assumption, we might consider automatic machines unable to influence the thoughts and intentions from which our actions take root. The key issue lies in the fact that an individual does not consciously engage in particular actions (automatisms), which (...) challenges the concept of free will in an individual’s complex behaviour. Despite this issue, not all automatisms that lack conscious will can be viewed as lacking free will. The paper examines whether classical philosophical concepts may weaken the strict determinist approach, which seeks to deny that individuals have free will due to the existence of automatic actions.

Once upon a time, there were no academic disciplines. There were no definitions, either, at least as we understand them. Plato and Aristotle changed both of those situations in ways that continue to influence Western thought. If Plato's and Xenophon's accounts are to be trusted, Socrates and Prodicus also deserve credit for early efforts to define words, thereby helping to formulate the classic Socratic/Platonic question "What is X?" And here we are, twenty-four hundred years later, still occasionally wrestling with how (...) to describe rhetoric, philosophy, and the relationship between the two.Drawing on my thirty-five years of thinking and writing about the classical and contemporary mediation of philosophy and...

Me propongo discutir la teoría del lenguaje que Platón sostiene en este diálogo. Su punto de vista busca evitar tanto los peligros del enfoque naturalista de Cratilo como el convencionalista de Hermógenes, aunque considero que su posición es más cercana a Hermógenes, quien destaca el carácter práctico del lenguaje (387c ss.) El horizonte que guía su indagación es la relación epistémica entre lógos y cosa (on y pragma), esto es, la pregunta sobre qué me permite conocer el lenguaje de las (...) cosas y del mundo. Las partes etimológicas del diálogo muestran que partir de la palabra atómica es erróneo, ya que una palabra desvinculada de la frase no crea conexión alguna entre lenguaje y mundo. Sólo podemos conocer o mostrar la esencia de algo mediante un entrelazamiento de palabras, en la que la oración es la unidad mínima significativa del lenguaje, a saber un sustantivo y un verbo. Por esto es importante, para mi lectura, el pasaje 432d11 – 433a1, en el cual se muestra el carácter indispensable del lógos para mostrar lo que una cosa verdaderamente es. (shrink)

Introduction“What reason is there to suppose that those who did know Parmenides’ poem necessarily thought that he had raised a real problem which they must try to deal with? Empedocles, perhaps also Anaxagoras, knew the poem, but they pursue a very different kind of philosophy from Zeno and Melissus: why, then, must we suppose that they are seeking an alternative answer to the problem posed by Parmenides, and that their ultimate material elements are to be seen as modifications of the (...) Eleatic ἓν έόν?“These rhetorical questions, taken from M. L. West's recent book,Early Greek Philosophy and the Orient,make a useful starting point for this inquiry. They are, of course, what the grammar books call “repudiating questions“: the answer hoped for is “no reason“. The argument with which Mr. West goes on to support his negative implication is not likely to convince many students of the Presocratics. He determinedly makes light of Parmenides’ chains of argument, apparently on the ground that “these were not the actual stages of Parmenides’ thinking” — as if Parmenides ought to have been writing his intellectual autobiography instead of a philosophical argument.

The version of the paradox of false judgement examined at Tht. 188c10–189b9 relies on the assumption that to judge falsehoods is to judge the things which are not. The presentation of the argument displays several syntactic ambiguities: at several points it allows the reader to adopt different syntactic connections between the components of sentences. For instance, when Socrates says that in a false judgement the cognizer is “he who judges the things which are not about anything whatsoever” (188d3–4), how should (...) the clause “about anything whatsoever” be construed? In common with “he who judges” and “the things which are not” (in which case the cognizer would be “he who judges about anything whatsoever the things which are not about it”), or exclusively with “he who judges” (in which case the cognizer would be “he who judges about anything whatsoever the things which are not”)? The most plausible answer is that both construals are envisaged. Accordingly, the argument has two branches corresponding to these two alternative construals. In particular, it attempts to show that in both cases the cognizer will address what does not exist – an impossibility. The idea that a false judgement is concerned with what is not about its reference has a clear echo in the Sophist. The way in which the problem is handled in the Theaetetus provides a hint that can help to find a solution for the hotly debated issue of the interpretation of the Sophist’s account of false statement.

In this paper I argue that Proclus’ criticism of the causality of Aristotle’s intellect is part of a general attack on Aristotle’s metaphysics. I show how Proclus criticises Aristotle for rejecting the One as a metaphysical principle and the metaphysical confusion that arises from this. Additionally, I claim that for Proclus Aristotle’s understanding of efficient causality differs from Plato’s and I discuss two of his arguments that Aristotle should have accepted the intellect as an efficient cause. As I show throughout, (...) Proclus differs in his approach to Aristotle from the harmonising agenda of Ammonius and Simplicius. (shrink)

The article attempts to highlight the development of the unity of medicine and philosophy in the context of combating epidemics of two early Greek thinkers Epimenides and Empedocles. The idea that Epimenides adheres to the divine origin of the disease is justified, but at the same time, in the process of ritual purification from the plague, it attracts elements of the Pythagorean view of healing, as well as close to Indo-Iranian traditions of the time. It is proved that in the (...) course of the development of ancient thought, the view of the disease also evolves “from myth to logos”, which leads to the understanding of this phenomenon in Empedocles as an ontological problem. Accordingly, it has been established that, for the Sicilian philosopher, mass diseases (epidemics) are caused primarily by the fact that he is more prevalent in the world. If the society is engulfed by hatred and malice, then diseases will inevitably emerge and increase. Instead, overcoming and disappearing of epidemics are possible because peace and harmony between people will prevail. The author substantiates the thesis that helping residents to overcome epidemics in various ancient cities, testifies to the great importance of the early Greek thinkers, who combined not only reflection but also praxis.

La actual crisis pedagógica que vive Occidente, constatada por todos aquellos educadores que deben enfrentarse diariamente a unos estándares cada vez más bajos y al consecuente perjuicio en lo que a la autoridad del profesorado se refiere, fue ya profetizada en su momento por Hannah Arendt (“The Crisis in Education”).

The aim of this paper is to make good philosophical sense of Plato’s portrayal of Zeno in the Phaedrus, both in itself and in the light of the characterization emerging from the Parmenides, where Plato describes Zeno as a faithful defender of the doctrine of the One-All professed by his teacher Parmenides. Therefore, starting from the example of the Parmenides, I will demonstrate that, from Plato’s point of view, the pairs of opposites that characterize Zeno’s arguments in the Phaedrus do (...) not constitute contrasting positions that the Eleatic thinker adopted at different times, but contradictory consequences deriving from the admission of multiplicity. Finally, this will allow us to truly understand both the reason why in the Phaedrus Zeno is counted among those who practice the ἀντιλογικὴ τέχνη and the sarcasm that Plato expresses through the epithet Palamedes.

The belief that primitive men lived like beasts and that civilisation developed out of these brutal origins is found in numerous ancient authors, both Greek and Latin. It forms part of certain theories about the beginnings of culture current in late antiquity. These are notoriously difficult to trace to their sources, but they already existed in some form in the fifth century b.c. One idea common to these theories is that of progress, and for this reason a fragment of Xenophanes (...) is sometimes cited as their remote prototype: ‘The gods did not reveal all things to men from the beginning; instead, by seeking, men discover what is better in time’. Mainly on the strength of this fragment, Ludwig Edelstein devoted the first chapter of his book The Idea of Progress in Classical Antiquity to Xenophanes, and W. K. C. Guthrie has even declared that there is good reason to attribute to him a fuller account of progress, one that would include details found in later authors who speak of the early life of mankind. One of these details is the statement that the life of primitive men was ‘brutal’ or ‘beastlike’ . In these authors the implication of that term varies from ‘unschooled in the basic crafts’ to ‘inhumanly violent and bloodthirsty’. In one sense or the other it is repeatedly encountered in ancient references to this subject. Accounts of primitive brutishness which make use of the word θηριώδης (or θηριωδς can be found in the Suppliants of Euripides, in the Hippocratic treatise On Ancient Medicine, in three passages of Diodorus, one of which is thought by some to contain Democritean doctrine, in four passages of Isocrates, in a fragment from a satyr-play Sisyphus which the ancient sources attribute variously to Euripides and to Critias, in a fragment of Athenion, in a second-century inscription, in Plutarch, in Tatian, in Themistius, and in a scholion to Euripides.
