Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1991. Philoponus’ long commentary on Aristotle’s definition of light sets up the major concerns, both in optics and theory of light, that are discussed here. Light was of special interest in Neoplatonism because of its being something incorporeal in the world of natural bodies. Light therefore had a special role in the philosophical analysis of the interpenetration of bodies and was also a paradigm for the soul-body problem. The book contains much about the physiology of vision as well as the propagation of light. Several chapters investigate the philosophical theory behind what came to be known as ‘multiplication of species’ in medieval light theory. These issues in the history of science are placed within an analysis of Neoplatonic development of the distinction between Aristotle’s kinesis and energeia. The book treats Philoponus’ philosophy of mathematical science from the point of view of matter, quantity, and three-dimensionality.

This book was released on 2014-06-01 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Philoponus' treatise Against Aristotle on the Eternity of the World, an attack on Aristotle's astronomy and theology is concerned mainly with the eternity and divinity of the fifth element, or 'quintessence', of which Aristotle took the stars to be composed. Pagans and Christians were divided on whether the world had a beginning, and on whether a belief that the heavens were divine was a mark of religion. Philoponus claimed on behalf of Christianity that the universe was not eternal. His most spectacular arguments, where wrung paradox out of the pagan belief in an infinite past, have been wrongly credited by historians of science to a period 700 years later. The treatise was to influence Islamic, Jewish, Byzantine and Latin thought, though the fifth element was defended against Philoponus even beyond the time of Copernicus. The influence of the treatise was not easy to trace before the fragments were assembled. Dr. Wildberg has brought them together for the first time and provided a summary which makes coherent sense of the whole. He has also studied a Syriac fragment, which reveals that the treatise originally contained an explicitly theological section on the Christian expectation of a new heaven and a new earth.

This book was released on 2015-08-14 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1973. Aristotle’s early works probably belong to the formative era of his philosophic thought and as such contribute vitally to the understanding and evaluation of the development of his philosophy. This book shows that the philosophy propagated in these lost works indicates an undeniable Platonism, and thus seems to conflict with the basic doctrines in the traditional treatises collected in the Corpus Aristotelicum. Was the author of the lost early works and the later preserved treatises one and the same person, or were some of these treatises written by members of the Early Peripatus? This, the second of two volumes, discusses in detail certain decisive aspects of Aristotle’s early works. Fascinating hypotheses and conjectures put forward here provoke discussion and further investigation in the ‘Aristotelian Problem’.

Available in PDF, EPUB and Kindle. Book excerpt: Until the launch of this series over fifteen years ago, the 15,000 volumes of the ancient Greek commentators on Aristotle, written mainly between 200 and 600 AD, constituted the largest corpus of extant Greek philosophical writings not translated into English or other European languages. This text by Philoponus rejects accounts of soul, or as we would say of mind, which define it as moving, as cognitive, or in physical terms. Chapter 3 considers Aristotle's attack on the idea that the soul is in motion. This was an attack partly on his teacher, Plato, since Plato defines the soul as self-moving. Philoponus agrees with Aristotle's attack on the idea that a thing must be in motion in order to cause motion. But he offers what may be Ammonius' interpretation of Plato's apparently physicalistic account of the soul in the Timaeus as symbolic. What we would call the mind-body relation is the subject of Chapter 4. Plato and Aristotle attacked a physicalistic theory of soul, which suggested it was the blend, ratio, or harmonious proportion of ingredients in the body.Philoponus attacked the theory too, but we learn from him that Epicurus had defended it. In Chapter 5, Philoponus endorses Aristotle's rejection of the idea that the soul is particles and of Empedocles' idea that the soul must be made of all four elements in order to know what is made of the same elements. He also rejects, with Aristotle, definitions of the soul as moving or cognitive as ignoring lower forms of life. He finally discusses Aristotle's rejection of Plato's localisation of parts of the soul in parts of the body, but asks if new knowledge of the brain and the nerves do not require some kind of localisation.

Book excerpt: Philoponus has been identified as the founder in dynamics of the theory of impetus, an inner force impressed from without, which, in its later recurrence, has been hailed as a scientific revolution. His commentary is translated here without the previously translated excursus, the Corollary on Void, also available in this series. Philoponus rejects Aristotle's attack on the very idea of void and of the possibility of motion in it, even though he thinks that void never occurs in fact. Philoponus' argument was later to be praised by Galileo. This volume contains the first English translation of Philoponus' commentary, as well as a detailed introduction, extensive explanatory notes and a bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: These chapters of Aristotle's treatise are about physical interactions. In his innovative commentary, Philoponus discusses Aristotle's idea that certain qualities of the elements are basic. In what way are they basic? he asks. To what extent can the other qualities be reduced to the basic ones? And if the other qualities depend on the basic ones, how is it that they can vary independently of each other when the basic qualities change? Philoponus develops the idea that the other qualities merely supervene on the basic ones, rather than resulting from them. Moreover, physical qualities admit of different ranges of variation, and so have different thresholds at which they appear or disappear. Philoponus also discusses Aristotle's idea that the elements and their basic qualities survive potentially when mixed together. He explains this by drawing a third sense of 'potential' out of Aristotle's texts to take the place of the two senses which Aristotle explicitly recognises. Philoponus adds further restrictions to Aristotle's principles of causation. Black can contaminate white, but the black in ebony does not have the right matter for affecting the white of milk. He asks why fluids can affect each other more easily than solids. In every case, Philoponus takes Aristotle's discussions further, and his ideas on the dependence of some qualities on others are very relevant to the continuing philosophical debate on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: The first five chapters of Aristotle's De Generatione et Corruptione distinguish creation and destruction from mere qualitative change and from growth. But what inspires Philoponus most in his commentary on these chapters is the topic of organic growth. How does it take place without ingested matter getting into the same place as the growing body? And how is personal identity preserved, if our matter is always in flux, and our form depends on our matter? If we do not depend on the persistence of matter why are we not immortal? Analogous problems of identity arise also for inanimate beings. These topics of identity over time and the principles of causation are still matters of intense philosophical discussion.

Download or read book Philoponus On Aristotle On the Soul 2 7 12 written by Philoponus, and published by Bloomsbury Publishing. This book was released on 2014-04-22 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this, one of the most original ancient texts on sense perception, Philoponus, the sixth century AD commentator on Aristotle, considers how far perceptual processes are incorporeal. Colour affects us in the same way as light which, passing through a stained glass window, affects the air, but colours only the masonry beyond. Sounds and smells are somewhat more physical, travelling most of the way to us with a moving block of air, but not quite all the way. Only the organ of touch takes on the tangible qualities perceived, because reception of sensible qualities in perception is cognitive, not physical. Neither light nor the action of colour involves the travel of bodies. Our capacities for psychological activity do not follow, nor result from, the chemistry of our bodies, but merely supervene on that. On the other hand, Philoponus shows knowledge of the sensory nerves, and he believes that thought and anger both warm us. This argument is used elsewhere to show how we can tell someone else's state of mind.

Available in PDF, EPUB and Kindle. Book excerpt: Subjects covered in this, the third and last, volume of translation of this work include: why the elements are four in number; what's wrong with Empedocles' theory of elements; how homogeneous stuffs, particularly the tissues of a living body, come to be and consist of the elements. The volume also contains very important discussions of causes, particularly of efficient cause, and of necessity in the sphere of generation and corruption. It will be of interest to the students of ancient philosophy and science (the commentary draws on earlier philosophical and medical texts); of Patristics and Christian Theology (it allows comparison of Philoponus' later creationist doctrine with his earlier ideas about generation); of medieval philosophy (this text was known to the Arabs; it is used by Avicenna and Averroes); and to anyone with interest in the metaphysics of causation, emergence, necessity and determinism.

Download or read book Philoponus On Aristotle Physics 4 1 5 written by Keimpe Algra and published by Bloomsbury Publishing. This book was released on 2014-04-22 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aristotle's account of place, in which he defined a thing's place as the inner surface of its nearest immobile container, was supported by the Latin Middle Ages, even 1600 years after his death, though it had not convinced many ancient Greek philosophers. The sixth century commentator Philoponus took a more common-sense view. For him, place was an immobile three-dimensional extension, whose essence did not preclude its being empty, even if for other reasons it had always to be filled with body. However, Philoponus reserved his own definition for an excursus, already translated in this series, The Corollary on Place. In the text translated here he wanted instead to explain Aristotle's view to elementary students. The recent conjecture that he wished to attract young fellow Christians away from the official pagan professor of philosophy in Alexandria has the merit of explaining why he expounds Aristotle here, rather than attacking him. But he still puts the students through their paces, for example when discussing Aristotle's claim that place cannot be a body, or two bodies would coincide. This volume contains an English translation of Philoponus' commentary, as well as a detailed introduction, extensive explanatory notes and a bibliography.

Available in PDF, EPUB and Kindle. Book excerpt: This is a post-Aristotelian Greek philosophical text, written at a crucial moment in the defeat of paganism by Christianity, AD 529, when the Emperor Justinian closed the pagan Neoplatonist school in Athens. Philoponus in Alexandria was a brilliant Christian philosopher, steeped in Neoplatanism, who turned the pagans' ideas against them. Here he attacks the most devout of the earlier Athenian pagan philosophers, Proclus, defending the distinctively Christian view that the universe had a beginning against Proclus' eighteen arguments to the contrary, which are discussed in eighteen chapters. Chapters 1-5 are translated in this volume.

Available in PDF, EPUB and Kindle. Book excerpt: Aristotle's Meteorology influenced generations of speculation about the earth sciences, ranging from atmospheric phenomena to earthquakes. The commentary of John Philoponus (6th century AD) on the opening three chapters of Meteorology is here translated for the first time into English by Dr Inna Kupreeva, building on the work of L.G. Westerink. Philoponus, who today is increasingly respected as a philosopher in his own right, here engages critically with Aristotle's views about the building-blocks of our world, its size and relationship to other heavenly bodies, and reception of warmth from the sun. The translation in this volume is accompanied by a detailed introduction, extensive commentary notes and a bibliography.

Download or read book Philoponus On Aristotle Meteorology 1 4 9 12 written by John Philoponus and published by Bristol Classical Press. This book was released on 2012-11-22 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of Philoponus' commentary on the Meteorology only that on chapters 1-9 and 12 of the first book has been preserved. It is translated in this series in two volumes, the first covering chapters 1-3; the second (this volume) chapters 4-9 and 12. The subjects discussed here include the nature of fiery and light phenomena in the sky, the formation of comets, the Milky Way, the properties of moist exhalation, and the formation of hail. Philoponus pays special attention to the distinction between the apparent and the real among the sky phenomena; he criticises Aristotle's theory of the Milky Way as sublunary, and argues for its origin in the heavenly realm; gives a detailed exposition of Aristotelian theory of antiperistasis, mutual replacement of the hot and the cold, as the mechanism of condensation and related processes. As in the first volume, Philoponus demonstrates scholarly erudition and familiarity with methods and results of post-Aristotelian Greek science. Despite the fragmented state of the work and the genre of commentary, the reader will find the elements of a coherent picture of the cosmos based on a radical re-thinking of Aristotelian meteorology and physics. The volume will be of interest to all students of ancient and medieval philosophy, history of Early Modern philosophy, history and philosophy of science.

Download or read book Philoponus On Aristotle Posterior Analytics 2 written by Philoponus, and published by A&C Black. This book was released on 2014-04-22 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Posterior Analytics contains Aristotle's philosophy of science. In Book 2, Aristotle asks how the scientist discovers what sort of loss of light constitutes lunar eclipse. The scientist has to discover that the moon's darkening is due to the earth's shadow. Once that defining explanation is known the scientist possesses the full scientific concept of lunar eclipse and can use it to explain other necessary features of the phenomenon. The present commentary, arguably ascribed to Philoponus incorrectly, offers some interpretations of Aristotle that are unfamiliar nowadays. For example, the scientific concept of a human is acquired from observing particular humans and repeatedly receiving impressions in the sense image or percept and later in the imagination. The impressions received are not only of particular distinctive characteristics, like paleness, but also of universal human characteristics, like rationality. Perception can thus in a sense apprehend universal qualities in the individual as well as particular ones. This volume contains an English translation of the commentary, accompanied by extensive commentary notes, an introduction and a bibliography.
