‘Saving the appearances’, , is a slogan that, in its time, stood or was made to stand for many different methodological positions in many different branches of ancient natural science. It is not my aim, in this paper, to attempt to tackle the subject as a whole. I shall concentrate on just one inquiry, astronomy. Nor, with astronomy, can I do justice to all the complexities of what was certainly one of the central methodological issues, if not the central issue, (...) in the history of ancient theoretical astronomy. I have a quite limited aim, to examine the foundations, and test the applicability, of a widespread and influential line of interpretation of ancient Greek astronomy according to which it was essentially, or at least predominantly, what we may call ‘instrumentalist’ in character—that is, broadly speaking, that Greek astronomical theories were devices or fictions put forward purely for the sake of calculations with no claims to correspond with physical reality.

Truth is one of the most debated topics in philosophy; Wolfgang Kunne presents a comprehensive critical examination of all major theories, from Aristotle to the present day. He argues that it is possible to give a satisfactory 'modest' account of truth without invoking problematic notions like correspondence, fact, or meaning. The clarity of exposition and the wealth of examples will make Conceptions of Truth an invaluable and stimulating guide for advanced students and scholars.

Seeking to reassess Plato's views on how we might investigate and explain the natural world, this book argues that many of the common charges against Plato (disinterest, ignorance, dismissal of observation) are unfounded, and that Plato had a series of important and cogent criticisms of the early atomists and other physiologoi. His views on science, and on astronomy and cosmology in particular, develop in interesting ways. It also argues that Plato can best be seen as someone who is struggling with (...) the foundations of scientific realism, and that he has interesting epistemological, cosmological and nomological reasons for his teleological approach.

"This is an excellent textbook on Neoplatonism which gives the reader a very concise and lucid overview of the basic doctrines and leading thinkers of the last great philosophy to emerge before the Christianization of the Roman Empire. I’ve no doubt that my students next semester will benefit from the analyses contained in the book. The contents of the chapters are very informative and adequately place developments in their socio-cultural context." --Michael B. Simmons, Auburn University at Montgomery.

The Peri ide^on is the only work in which Aristotle systematically sets out and criticizes arguments for the existence of Platonic forms. Gail Fine presents the first full-length treatment in English of this important but neglected work. She asks how, and how well, Aristotle understands Plato's theory of forms, and why and with what justification he favors an alternative metaphysical scheme. She examines the significance of the Peri ide^on for some central questions about Plato's theory of forms--whether, for example, there (...) are forms corresponding to every property or only to some, and if only to some, then to which ones; whether forms are universals, particulars or both; and whether they are meanings, properties or both. Fine also provides a general discussion of Plato's theory of forms, and of our evidence about the Peri ide^on and its date, scope, and aims. While she pays careful attention to the details of the text, she also relates it to contemporary philosophical concerns. The book will be valuable for anyone interested in metaphysics ancient or modern. (shrink)

In this paper I show that Proclus is an adherent of the Classical Model of Science as set out elsewhere in this issue (de Jong and Betti 2008), and that he adjusts certain conditions of the Model to his Neoplatonic epistemology and metaphysics. In order to show this, I develop a case study concerning philosophy of nature, which, despite its unstable subject matter, Proclus considers to be a science. To give this science a firm foundation Proclus distills from Plato’s Timaeus (...) the basic concepts Being and Becoming and a number of basic propositions, among others the quasi-definitions of the basic concepts. He subsequently explains the use of these quasi-definitions, that are actually epistemic guides, in such a way that he obtains a connection between a rational and an empirical approach to the natural world. A crucial task in establishing the connection is performed by the faculty of doxa and by geometrical conversion. The result is that Proclus secures a universal, necessary and known foundation for all of philosophy of nature. (shrink)

Proclus defends the Platonic view that the heavens consist in (the highest gradations) of all four elements. He attacks Aristotle's view that the heavens consist in a distinct, fifth element.

An examination of the emergence of the phenomenon of deductive argument in classical Greek mathematics.

Following strict rules of interpretation, this book focuses on the ideas in Plato's early and middle dialogues that lie within the fields now called logic and methodology, specifically elenchus and dialectic and the method of hypothesis.

Proclus, head of the Philosophy School at Athens for fifty years, was one of the leading philosophical figures in Late Antiquity. Lucas Siorvanes here introduces Proclus to English-language readers, discussing his metaphysics and theory of knowledge and focusing in particular on his Neo-Platonism. Proclus lived in the turbulent fifth century A.D., a time of struggles among Christians, Jews, and pagans, the invasion of Attila the Hun, the fall of the Western Roman Empire, and the rise of the Eastern Roman Empire (...) in Byzantium. While Late Antiquity has been regarded as a time of superstition and forbiddingly complex philosophies, recent scholarship has shown it to be full of cultural and intellectual vigor. During Proclus's tenure as head of the Philosophy School, he systematized Neo-Platonism as the summit of ancient Greek thought, brought it to its peak of influence, and became responsible for the form in which it was transmitted to the Byzantine, Western European, and Islamic civilizations. Siorvanes's extensive original research presents Proclus as much more than just a metaphysician. He surveys all of Proclus's philosophical interests—including religion, physics, astronomy, mathematics, and poetry—revealing the philosopher's central concern with the problems of being and knowledge and relating the ideas of Proclus to those of such other major thinkers as Plato, Aristotle, and Ptolemy. To help the newcomer, Siorvanes supplies more than 200 quotations from Proclus's works. He also traces the impact of Proclus's Neo-Platonism across cultures, religions, and centuries, in such diverse areas as Christian and Islamic theologies, Renaissance art, Kepler's astronomy, Romantic poetry, Emerson's thought, modern philosophy and science, and current popular phrases.

The book is written for anyone seriously interested in Plato's thought and in the history of literary theory or of rhetoric. No knowledge of Greek is required. The focus of this account is on how the resources both of persuasive myth and of formal argument, for all that Plato sets them in strong contrast, nevertheless complement and reinforce each other in his philosophy.

This book explores the dynamic relationship between myth and philosophy in the Presocratics, the Sophists, and in Plato - a relationship which is found to be more extensive and programmatic than has been recognized. The story of philosophy's relationship with myth is that of its relationship with literary and social convention. The intellectuals studied here wanted to reformulate popular ideas about cultural authority and they achieved this goal by manipulating myth. Their self-conscious use of myth creates a self-reflective philosophic sensibility (...) and draws attention to problems inherent in different modes of linguistic representation. Much of the reception of Greek philosophy stigmatizes myth as 'irrational'. Such an approach ignores the important role played by myth in Greek philosophy, not just as a foil but as a mode of philosophical thought. The case studies in this book reveal myth deployed as a result of methodological reflection, and as a manifestation of philosophical concerns. (shrink)

Anyone who has read Plato’s Republic knows it has a lot to say about mathematics. But why? I shall not be satisfied with the answer that the future rulers of the ideal city are to be educated in mathematics, so Plato is bound to give some space to the subject. I want to know why the rulers are to be educated in mathematics. More pointedly, why are they required to study so much mathematics, for so long?

This paper is a critical examination the claim that Galileo was a Platonist. It contends that neither his use of mathematics (as Koyre asserts), nor his hypothetic-deductive method of testing (as Cassirer maintains), nor a realistic interpretation of this abstract theories (as Crombie argues) offers reasonable and consistent evidence that Galileo shared or advocated the metaphysics or methods of Plato.

In Proclus dianoia is the Soul's thinking activity, through which it makes itself into a divided image of Nous. This dissertation examines various aspects of Procline dianoia. Dianoia's thoughts are logoi, because in the Greek philosophical tradition, logos came to mean a division of a prior unity . Proclus' theory of dianoia rejects induction, and is a conscious development of Plato's theory of anamnesis , because induction is unable to yield a true universal . The source of Soul's logoi is (...) not a pre-natal vision of reality, but rather its ontological dependence on Nous. The Soul's ousia is a fullness of logoi which are images of the eide in Nous. The Soul projects these multiple oudiodeis logoi into even greater multiplicity. In so doing, Soul makes itself into the image of Nous, and the paradigm of Body. For this reason all dianoia is metaphorical, because it either understands Nous through the image which itself is, or understands Body through itself as paradigm . Dianoia, therefore, has two parts. Dialectic is the Soul's grasp of Nous through itself as image, and mathematics is the Soul's grasp of Body through itself as paradigm . The Soul's attention to Body may cause it to cease its dianoetic activity, because it takes on Body's passivity. Philosophical discussion may rescue such a fallen soul, turning it back towards itself, away from the body. In Procline terms, philosophy restores the Soul's autokinesis, or self-motion . The particular Nous of which Soul is an image, and which dianoia divides, is the Nous which serves as a measure for Soul's dividing activity. And because Time is the measure of the Soul's motion, this particular Nous is the monad of Time . Dianoia has as its aim to leave behind all divided thinking, and to be content with the unity of Nous, and the simplicity of the One. This is accomplished through that in the Soul which is higher than dianoia, the nous of the Soul, and its own one. (shrink)

A study examining how Plotinus relates language not only to philosophical reasoning, but to noesis - the intuitive and comprehensive act of intellection, and how he relates language to Union with the One, a union beyond speech and beyond noesis.

"Aristotle versus Plato. For a long time that is the angle from which the tale has been told, in textbooks on the history of philosophy and to university students. Aristotle's philosophy, so the story goes, was au fond in opposition to Plato's. But it was not always thus."--from the Introduction In a wide-ranging book likely to cause controversy, Lloyd P. Gerson sets out the case for the "harmony" of Platonism and Aristotelianism, the standard view in late antiquity. He aims to (...) show that the twentieth-century view that Aristotle started out as a Platonist and ended up as an anti-Platonist is seriously flawed. Gerson examines the Neoplatonic commentators on Aristotle based on their principle of harmony. In considering ancient studies of Aristotle's Categories, Physics, De Anima, Metaphysics, and Nicomachean Ethics, the author shows how the principle of harmony allows us to understand numerous texts that otherwise appear intractable. Gerson also explains how these "esoteric" treatises can be seen not to conflict with the early "exoteric" and admittedly Platonic dialogues of Aristotle. Aristotle and Other Platonists concludes with an assessment of some of the philosophical results of acknowledging harmony. (shrink)

An investigation of Proclus' logic of the syllogistic and of negations in the Elements of Theology, On the Parmenides, and Platonic Theology. It is shown that Proclus employs interpretations over a linear semantic structure with operators for scalar negations (hypemegationlalpha-intensivum and privative negation). A natural deduction system for scalar negations and the classical syllogistic (as reconstructed by Corcoran and Smiley) is shown to be sound and complete for the non-Boolean linear structures. It is explained how Proclus' syllogistic presupposes converting the (...) tree of genera and species from Plato's diairesis into the Neoplatonic linear hierarchy of Being by use of scalar hyper and privative negations.

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)

This book was first published in 1991. The study of ancient science and its relations with Greek philosophy has made a significant and growing contribution to our understanding of ancient thought and civilisation. This collection of articles on Greek science contains fifteen of the most important papers published by G. E. R. Lloyd in this area since 1961, together with three newer articles. The topics range over all areas and periods of Greek science, from the earliest Presocratic philosophers to Ptolemy (...) and Galen. In each case the article is preceded by an introduction that assesses scholarly debate on the topic since the original publication. Professor Lloyd also suggests modifications and developments to his own position in the light of those debates and his own further research. (shrink)

Plato's dialogue the Timaeus-Critias presents two connected accounts, that of the story of Atlantis and its defeat by ancient Athens and that of the creation of the cosmos by a divine craftsman. This book offers a unified reading of the dialogue. It tackles a wide range of interpretative and philosophical issues. Topics discussed include the function of the famous Atlantis story, the notion of cosmology as 'myth' and as 'likely', and the role of God in Platonic cosmology. Other areas commented (...) upon are Plato's concepts of 'necessity' and 'teleology', the nature of the 'receptacle', the relationship between the soul and the body, the use of perception in cosmology, and the work's peculiar monologue form. The unifying theme is teleology: Plato's attempt to show the cosmos to be organised for the good. A central lesson which emerges is that the Timaeus is closer to Aristotle's physics than previously thought. (shrink)

The key phrase eikōs muthos is standardly translated ‘a likely tale’, suggesting an empiricist philosophy of science quite alien to Plato’s outlook. I argue for translating, in the first instance, ‘a reasonable myth’, and focus on the point that the reason involved in world-making is practical, not theoretical. This should make a significant differenceto how we assess the Demiurgic arguments reported to us in the dialogue.

The word myth is commonly thought to mean a fictional story, but few know that Plato was the first to use the term muthos in that sense. He also used muthos to describe the practice of making and telling stories, the oral transmission of all that a community keeps in its collective memory. In the first part of Plato the Myth Maker , Luc Brisson reconstructs Plato's multifaceted description of muthos in light of the latter's Atlantis story. The second part (...) of the book contrasts this sense of myth with another form of speech that Plato believed was far superior: the logos of philosophy. Gerard Naddaf's substantial introduction shows the originality and importance both of Brisson's method and of Plato's analysis and places it in the context of contemporary debates over the origin and evolution of the oral tradition. "[Brisson] contrasts muthos with the logos found at the heart of the philosophical reading. [He] does an excellent job of analyzing Plato's use of the two speech forms, and the translator's introduction does considerable service in setting the tone."-- Library Journal. (shrink)
