Anaxagoras

In my paper, I shall provide a reading of Diogenes of Apollonia such that his understanding of the metaphysics of differentiation and of individual ensoulment may constitute an ingenious answer to the problems of his time. To this extent, I will argue that Diogenes' worldview solves the difficulties of Anaxagoras' metaphysics and successfully integrates mentality in a causally closed conception of nature. Finally, I will suggest that a Diogenes-inspired approach might be relevant to treat some pressing concerns in the contemporary (...) philosophy of mind – thus demonstrating how his production might offer some interesting solutions for the problems of our time too.

Anaxagoras’ theory of the nous constitutes one aspect of his philosophy particularly interesting for Aristotle. However, he maintains a somewhat bivalent position about it: on the one hand, he praises the Presocratic philosopher for putting the nous as the first principle, while on the other, he shows his disappointment. According to him, Anaxagoras’ nous works insufficiently in the universe, but it is also the cause of goodness, indeed it is the Good capitalized. Our goal is to explain how Aristotle was (...) able to develop both types of seemingly inconsistent discourse concerning Anaxagorean nous. Two solutions to this dilemma are offered: even although some teleology exists in Anaxagoras’ philosophy, it is insufficient for Plato and Aristotle; the reception of the thought of Anaxagoras in later authors still before Aristotle furtively associates goodness with nous.

In order to show the relevance of the Presocratic thinkers, certain achievements are sometimes presented as anticipations of some discoveries made by contemporary science. Anaxagoras’ explanation for the origin of the world in particular has been compared to the Big Bang theory by some scholars. The purpose of this article is to show why this theory is very different from Anaxagoras’ view of the origin of the world. For Anaxagoras, the world does not start from a tiny expanding particle. Rather, (...) already before the beginning of the cosmos, there is a totality filled by a primordial mixture. The world emerges in it as a kind of dilating bubble. The cosmos grows by means of a whirl which absorbs the exterior mixture, deconstructing it to give origin to the different things that we know. This vortex is a unique explanation for multiple phenomena, not only helping to understand the origin of the world but also the present cosmos, which is in continuous expansion, since cosmogenesis has not been interrupted.

This articles explores Philo's variant for Anaxagoras' 21a DK fragment as an alternative for Sextus Empiricus' reading (ὄψις τῶν ἀδήλων τὰ φαινόμενα). Philo's variant (πίστις τῶν ἀδήλων τὰ ἐμφανῆ: De vita Mosis, I, 280) is not present in the current literature on Presocratics but his reading could be a reliable form for this fragment.

I argue that a common interpretation of DA 3.4, which sees Aristotle as there rejecting Anaxagoras’s account of mind, is mistaken. Instead, I claim that, in providing his solution to the main puzzles of this chapter, Aristotle takes special care to preserve the essential features that he thinks Anaxagoras ascribes to mind, namely, its ability to know all things, its being unmixed, and its inability to be affected by mixed objects.

For Anaxagoras, both before the beginning of the world and in the present, “all is together” and “everything is in everything.” Various modern interpretations abound regarding the identity of this “mixture.” It has been explained as an aggregation of particles or as a continuous “fusion” of different sorts of ingredients. However—even though they are not usually recognized as a distinct group—there are a number of other scholars who, without seemingly knowing each other, have offered a different interpreta- tion: Anaxagoras’ mixture (...) as an “interpenetration” of different ingredients, which are as far-extended as the whole mixture is. As a result, there are different entities occupying the same place at the same time. This explanation assigns to Anaxagoras the same model of mixture which was later used by the Stoics. A new book by Marmodoro helps us to clarify this position. (shrink)

The philosophy of Diogenes pays special attention to knowledge. Diogenes bases his thought on the well-known thesis of Parmenides which identifies einai and noein, combining it with the nous of Anaxagoras. According to Diogenes, the intellect (noesis) is embodied in the formal features of things and therefore is powerful, like the nous of Anaxagoras. The aim of the following pages is to show, in confrontation with Laks, that noesis does not homogenize the cosmos, but rather it diversifies it.

Aristotle introduced in the history of the reception of Anaxagoras the term ‘homoiomerous’. This word refers to substances whose parts are similar to each other and to the whole. Although Aristotle’s explanations can be puzzling, the term ‘homoiomerous’ may explain an authentic aspect of Anaxagoras’ doctrine reflected in the fragments of his work. Perhaps one should find a specific meaning for the term ‘homoiomerous’ in Anaxagoras, somewhat different from the one present in Aristotle. This requires a review of the sense (...) of the two terms involved in it: ‘homoios’ and ‘moira’. In other words, the following questions should be answered: what realities are named parts and to what whole they belong? On the other hand, which similarity do they have to each another and to the whole? The author concludes that the parts are “all things,” which resemble each other and the universe as a whole because, according to Anaxagoras, they are all composed of all things. (shrink)

Nossa pesquisa é pautada na tentativa de compreender alguns conceitos da filosofia aristotélica, mais especificamente as noções de forma, matéria, privação e potência, e um pouco sobre a metodologia usada pelo filósofo. As linhas abaixo compõem um capítulo da minha monografia de fim de curso, intitulada Dialogo com a tradição: A conquista de novas convicções acerca dos princípios de natureza no primeiro livro da Física aristotélica, realizada na Universidade Federal Rural do Rio de Janeiro. Nela tratei a respeito da metodologia (...) de Aristóteles que, dentre outras coisas, passa pela crítica à filosofia precedente, esclarecendo assim algumas questões do primeiro livro da Física – livro no qual o filósofo tenta determinar quantos e quais são os princípios da natureza.

The fifth century BC is one of the most brilliant of Greek history. Pericles, as the leader of a splendid Athens, promoted the entry into his polis of the new scientific movement that until then had developed primarily in Ionia and in the Italian peninsula. However, their research raised suspicions among the Athenians, who regarded it as a risk for traditional religion. In spite of the somewhat flexible and plural character of the Greek religion, in this period three famous trials (...) took place in which different philosophers were tried for impiety: Anaxagoras, Protagoras and Socrates. The controversy between religion and philosophy can lead us to an oversimplification of the facts. Thus, several modern scholars have understood philosophy as an exorcism of myth and therefore as something necessarily guiding to a progressive elimination of the divine from the worldview. We intend to interpret this conflict only as a change in understanding of the divinity, rather than a suppression of it. This has, of course, effects on religion, but it does not drag inevitably to irreligion. (shrink)

Bu makalede Milet Okulu Filozofları ve ilk materyalistler olarak anılan Thales, Anaksimandros ve Anaksimenes’in ontolojileriyle ilişkili olarak arkhe arayışı içerisinde tanrıyla ilgili görüşlerine yer verilecektir. Bazı düşünürler tarafından tanrı tanımaz olarak nitelendirilen Miletli filozofların evrenin ilk maddesi nedir sorusuna vermiş oldukları yanıtların aslında o dönemki Antik Yunan din anlayışıyla bazı önemli noktalarda bağdaştığı gösterilecektir. Makalenin sonunda bu düşünürlerin kendilerine ait bir teoloji ve tanrı düşüncesine sahip oldukları sonucuna varılacaktır.

This article aims at clarifying some issues raised by a recent book of Daniel W. Graham about the Presocratic cosmology. It particularly intends to shed some light on the understanding of Anaxagoras’ universe by suggesting some reasons why, despite Graham’s opinion, it is still possible to think that the stars were flat according to him. Another goal is highlighting the importance of the comprehensive physical theory of Anaxagoras, based on a circular motion called perichoresis, which would explain diverse phenomena in (...) a consistent way by introducing simplicity in his cosmology.

An Italian abstract of my thesis, which contains an interpretation of the most important issues of Anaxagoras' philosophy and the early history of his reception (among his disciples, the Academy and, prominently, Aristotle).

¿Cuál es el origen de todas las cosas? A pesar de su gran diversidad, ¿tienen una raíz común? ¿Tuvo el mundo un comienzo? ¿Cómo surgió la vida en la tierra? Tales preguntas, que aún provocan a los científicos, fueron formuladas por vez primera por los primeros pensadores griegos. Anaxágoras responde a ellas poniendo al inicio del tiempo una confusa mezcla de todas las cosas sobre la cual obró un ser llamado Intelecto, quien dio lugar al orden del mundo que hoy (...) contemplamos. Con ello, este autor presocrático comienza a plantear algunas cuestiones filosóficas que perdurarán hasta nuestros días: la constitución de la materia, la naturaleza del conocimiento sensorial e intelectual, la intervención de Dios en el mundo… Este libro pretende analizar cuidadosamente la filosofía de Anaxágoras prestando atención a los dos aspectos principales de su doctrina: la mezcla e Intelecto. Su comprensión de la realidad física como una mezcla tiene consecuencias filosóficas de gran interés y constituye quizá la más sugestiva entre las primeras concepciones de la materia. Por otro lado, Intelecto es, según Anaxágoras, quien provoca la variedad de los seres a través del movimiento. Así, nuestro filósofo distingue del sustrato material la causa de sus cambios, la cual se hallaría, además, dotada de inteligencia. Tales rasgos de la filosofía de Anaxágoras atrajeron la atención de los grandes filósofos clásicos, particularmente de Aristóteles. El segundo gran objetivo de este libro es, pues, recorrer el camino por el cual discurrieron las enseñanzas de Anaxágoras, desde que fueron expuestas por él en Atenas, justo durante el siglo que definió la preponderancia intelectual de dicha polis durante siglos, hasta que llegaron a oídos de Aristóteles, el testigo más determinante para comprender a Anaxágoras.

Encyclopedia entry about Anaxagoras, the presocratic philosopher: Life, works, mixture, nous, biological and cosmological problems, and a bibliography.

Anaxagoras’ “nous” has a cosmological value. Additionally, it has inspired interesting reflections in order to understand metaphysically the intellect. The question we want to answer is twofold. On one hand, we will inquire whether or not Anaxagoras has understood correctly the nature of the intellect. On the other hand, we will discern if our author has understood the peculiarity of consciousness. The answer to these questions will probably be negative. Notwithstanding that, it will be possible to ask whether or not (...) Anaxagoras was able to detect at least the basic elements for a metaphysics of the intellect and, consequently, for an ontology of consciousness. (shrink)

Simplicius’ project of harmonizing previous philosophers deserves to be taken seriously as both a philosophical and an interpretive project. Simplicius follows Aristotle himself in developing charitable interpretations of his predecessors: his distinctive project, in the Neoplatonic context, is the rehabilitation of the Presocratics (especially Parmenides, Anaxagoras and Empedocles) from a Platonic-Aristotelian perspective. Simplicius’ harmonizations involve hermeneutic techniques which are recognisably those of the serious historian of philosophy; and harmonization itself has a distinguished history as a constructive philosophical method.
