This is the first book to analyze systematically crucial aspects of ancient Greek philosophy in their original context of mystery, religion, and magic. The author brings to light recently uncovered evidence about ancient Pythagoreanism and its influence on Plato, and reconstructs the fascinating esoteric transmission of Pythagorean ideas from the Greek West down to the alchemists and magicians of Egypt, and from there into the world of Islam.

The so-called "Theology of Aristotle" is a translation of the Enneads of Plotinus, the most important representative of late ancient Platonism. It was produced in the 9th century CE within the circle of al-Kindī, one of the most important groups for the early reception of Greek thought in Arabic. In part because the "Theology" was erroneously transmitted under Aristotle's authorship, it became the single most important conduit by which Neoplatonism reached the Islamic world. It is referred to by such thinkers (...) as al-Fārābī, in an attempt to demonstrate the agreement between Platonism and Aristotelianism, Avicenna, who wrote a set of comments on the text, and later on thinkers of Safavid Persia including Mullā Ṣadrā. Yet the "Theology" is not just a translation. It may in fact more accurately be described as a creative paraphrase, which takes frequent liberties with the source text and even includes whole paragraphs' worth of new material. Adamson's book offers a philosophical interpretation of the changes introduced in the Arabic version. It is argued that these changes were in part intended to show the relevance of Plotinus' thought for contemporary Islamic culture, for instance by connecting the Neoplatonist theory of the First Principle to theological disputes within Islam over the status of God's attributes. At the same time the paraphrase reflects a tendency to harmonize the various strands of Greek thought, so that a critique by Plotinus of Aristotle's theory of the soul is subtly changed into a defense of Aristotle's theory against a possible misinterpretation. The upshot, or so Adamson argues, is that the "Theology" needs to be read as an original philosophical work in its own right, and understood within the context of the ʿAbbāsid era. (shrink)

In this paper I argue that the logos, the primary object of knowledge in Heraclitus’ epistemology, is a unity both as an object of knowledge and as an instance of being rather than becoming. Section I begins with discussions of knowledge and Heraclitus’ conception of logos; section II is concerned with knowledge and unity. The two later sections of the paper explore the consequences of the account I attribute to Heraclitus: section III considers being, unity, and change; and section IV (...) discusses Heraclitus’ views of knowledge and sense perception.

The object of this paper is to show that, in the sixth and fifth centuries B.C., two different and radically opposed systems of thought were elaborated within the Pythagorean school. They may be called respectively the mystical system and the scientific. All current accounts of Pythagoreanism known to me attempt to combine the traits of both systems in one composite picture, which naturally fails to hold together. The confusion goes back to Aristotle, who usually speaks indiscriminately of ‘the Pythagoreans,’ though (...) now and then the phrase ‘some Pythagoreans’ indicates that he was aware of different currents within the school.

The most comprehensive collection of Neoplatonic writings available in English, this volume provides translations of the central texts of four major figures of the Neoplatonic tradition: Plotinus, Porphyry, Iamblichus, and Proclus. The general Introduction gives an overview of the period and takes a brief but revealing look at the history of ancient philosophy from the viewpoint of the Neoplatonists. Historical background--essential for understanding these powerful, difficult, and sometimes obscure thinkers--is provided in extensive footnotes, which also include cross-references to other works (...) relevant to particular passages.

W.K.C. Guthrie has written a survey of the great age of Greek philosophy - from Thales to Aristotle - which combines comprehensiveness with brevity. Without pre-supposing a knowledge of Greek or the Classics, he sets out to explain the ideas of Plato and Aristotle in the light of their predecessors rather than their successors, and to describe the characteristic features of the Greek way of thinking and outlook on the world. Thus The Greek Philosophers provides excellent background material for the (...) general reader - as well as providing a firm basis for specialist studies. (shrink)

The purpose of this paper is to investigate the source of Plutarch's inspiration for the impressive discourse which he presents from the lips of Ammonius in the De E apud Delphos, and in particular for the following much-quoted passage.

Professor G. E. L. OWEN has demonstrated that Parmenides' Way of Truth is to be taken as a self-contained logical argument. The basis for this argument is a proof that whatever we may choose to think about The first stage of this proof is contained in B 2. According to Owen's reconstruction of the argument, Parmenides' method is to take the three possible answers to the question and rule out two of them. This view involves giving equal status to each (...) of the two wrong answers; but Parmenides appears not to do this. At the start of B 2 he undertakes to tell us. (shrink)

The role and precise significance of Intelligible Matter in the philosophy of Plotinus has been neglected or dismissed with many questions unanswered. In view of the fact that, unless this role can be properly understood, the whole doctrine of the procession of the Second Hypostasis must remain mysterious, this paper is intended to shed light on two important aspects of that Hypostasis: the nature of Intelligible Matter itself and the relation of that Matter to the Forms.

The great number of contradictory statements which confront us when we examine the various explanations of Anaxagoras' philosophy make it more than usually important to decide what is to be admitted as first-hand evidence and what is not. I purpose, then, to begin by accepting the barest minimum of data, and I shall try to exclude any direct comments upon Anaxagoras' work by later writers. Sufficient justification for such a course may be found in the bewildering masses of confusion which (...) have gathered around his teaching. (shrink)

The following suggestions for the interpretation of Parmenides and Melissus can be grouped for convenience about one problem. This is the problem whether, as Aristotle thought and as most commentators still assume, Parmenides wrote his poem in the broad tradition of Ionian and Italian cosmology. The details of Aristotle's interpretation have been challenged over and again, but those who agree with his general assumptions take comfort from some or all of the following major arguments. First, the cosmogony which formed the (...) last part of Parmenides' poem is expressly claimed by the goddess who expounds it to have some measure of truth or reliability in its own right, and indeed the very greatest measure possible for such an attempt. Second, the earlier arguments of the goddess prepare the ground for such a cosmogony in two ways. For in the first place these arguments themselves start from assumptions derived from earlier cosmologists, and are concerned merely to work out the implications of this traditional material. And, in the second place, they end by establishing the existence of a spherical universe: the framework of the physical world can be secured by logic even if the subsequent introduction of sensible qualities or ‘powers’ into this world marks some decline in logical rigour.

This study proposes that Neoplatonism, while not a modern philosophy, is philosophy in the modern sense. Lloyd analyzes the key structures that underlie the dogmas of the Neoplatonic world picture, including the concept of emanation, the return of the soul to the One, the place of mystical knowledge, epistemology, and Porphyry's theory of predication, and shows that they rest on original but intelligible concepts and arguments.

Neoplatonism is a term used to designate the form of Platonic philosophy that developed in the Roman Empire from the third to the fifth century AD and that based itself on the corpus of Plato's dialogues. Sara Rappe's challenging study analyses Neoplatonic texts themselves using contemporary philosophy of language. It covers the whole tradition of Neoplatonic writing from Plotinus through Proclus to Damascius. Addressing the strain of mysticism in these works, the author shows how these texts reflect actual meditational practices, (...) methods of concentrating the mind, and other mental disciplines that informed the tradition as a whole. In providing such a broad survey of Neoplatonic writing, the book will appeal to classical philosophers classicists as well as students of religious studies. (shrink)

1. It is evident that the contrast between ‘life’ and ‘death’ is an important one for Heraclitus. But his words remain cryptic, perhaps more so on this subject than on most others. Ideally, any elucidation would occur as an application of, and as in its turn confirming, some overall view of his theorising activity. The suggestions which follow are not intended to achieve that. I work within the well-worn assumptions that Heraclitus is putting forward a “general theory of the soul” (...) that goes substantially beyond the evidence available; and that Heraclitus is a highly systematic theorist, and in particular that there is a close analogy between his theory of the soul and his theory of the cosmos, with fire playing the central role in each, and each being an application of the master-pattern of ‘unity-in-opposites’. I hope to show that, even within this “traditional” approach, there is room for new insights, if we respect both the Homeric-Hesiodic background and Heraclitus’ own method of self-expression. (shrink)
