John Philoponus on Physical Place


Book Description

This book examines the place of physical bodies, a major topic of natural philosophy that has occupied philosophers since antiquity. Aristotle’s conceptions of place (topos) and the void (kenon), as expounded in the Physics, were systematically repudiated by John Philoponus (ca. 485-570) in his philosophical commentary on that work. The primary philosophical concern of the present study is the in-depth investigation of the concept of place established by Philoponus, putting forward the claim that the latter offers satisfactory solutions to problems raised by Aristotle and the Aristotelian tradition regarding the nature of place. Philoponus’ account proposes a specific physical model of how physical bodies exist and move in place, and regards place as an intrinsic reality of the physical cosmos. Due to exactly this model, his account may be considered as strictly pertaining to the study of physics, thereby constituting a remarkable episode in the history of philosophy and science.




Philoponus: Against Proclus on the Eternity of the World 12-18


Book Description

In chapters 12-18 of Against Proclus, Philoponus continues to do battle against Proclus' arguments for the beginninglessness and everlastingness of the ordered universe. In this final section there are three notable issues under discussion. The first concerns the composition of the heavens and its manner of movement. Philoponus argues against the Aristotelian thesis that there is a fifth heavenly body that has a natural circular motion. He concludes that even though the celestial region is composed of fire and the other three elements, it can move in a circle by the agency of its soul, and that this circular motion is not compromised in any way by the innate natural motion of the fire.Chapter 16 contains an extended discussion of the will of God and His relation to particulars. Here Philoponus addresses issues that become central to medieval philosophical and theological discussions, including the unity, timelessness and indivisibility of God's will. Finally, throughout these seven chapters Philoponus is engaged in a detailed exegesis of Plato's Timaeus which aims to settle a number of familiar interpretive problems, notably how we should understand the pre-cosmic state of disorderly motion, and the statement that the visible cosmos is an image of the paradigm. Philoponus' exegetical concerns culminate in chapter 18 with an extensive discussion of Plato's attitude to poetry and myth.




Philoponus: On Aristotle on the Soul 1.3-5


Book Description

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.




Philoponus: Corollaries on Place and Void with Simplicius: Against Philoponus on the Eternity of the World


Book Description

In the Corollaries on Place and Void, Philoponus attacks Aristotle's conception of place as two-dimensional, adopting instead the view more familiar to us that it is three-dimensional, inert and conceivable as void. Philoponus' denial that velocity in the void would be infinite anticipated Galileo, as did his denial that speed of fall is proportionate to weight, which Galileo greatly developed. In the second document Simplicius attacks a lost treatise of Philoponus which argued for the Christians against the eternity of the world. He exploits Aristotle's concession that the world contains only finite power. Simplicius' presentation of Philoponus' arguments (which may well be tendentious), together with his replies, tell us a good deal about both Philosophers.




Philoponus: Against Proclus On the Eternity of the World 9-11


Book Description

In one of the most original books of late antiquity, Philoponus argues for the Christian view that matter can be created by God out of nothing. It needs no prior matter for its creation. At the same time, Philoponus transforms Aristotle's conception of prime matter as an incorporeal 'something - I know not what' that serves as the ultimate subject for receiving extension and qualities. On the contrary, says Philoponus, the ultimate subject is extension. It is three-dimensional extension with its exact dimensions and any qualities unspecified. Moreover, such extension is the defining characteristic of body. Hence, so far from being incorporeal, it is body, and as well as being prime matter, it is form - the form that constitutes body. This uses, but entirely disrupts, Aristotle's conceptual apparatus. Finally, in Aristotle's scheme of categories, this extension is not to be classified under the second category of quantity, but under the first category of substance as a substantial quantity. This volume contains an English translation of Philoponus' commentary, detailed notes and introduction, and a bibliography.

Philoponus: Against Proclus On the Eternity of the World 1-5


Book Description

Philoponus was a brilliant Christian philosopher, steeped in Neoplatanism, who turned the pagans' ideas against them. Here he attacks the devout Athenian pagan philosopher, Proclus, defending the Christian view that the universe had a beginning against Proclus' arguments to the contrary.




Philoponus: Against Aristotle on the Eternity of the World


Book Description

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.




Philoponus: On Aristotle Physics 1.1-3


Book Description

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. In this, the first half of Philoponus' analysis of book one of Aristotle's Physics, the principal themes are metaphysical. Aristotle's opening chapter in the Physics is an abstract reflection on methodology for the investigation of nature, or 'physics'. Aristotle suggests that one must proceed from things that are familiar but vague, and derive more precise but less obvious principles to constitute genuine knowledge. His controversial claim that this is to progress from the universal to the more particular occasions extensive apologetic exegesis, typical of Philoponus' meticulous and somewhat pedantic method. Philoponus explains away the apparent conflict between the 'didactic method' (unavoidable in physics) and the strict demonstrative method described in the Analytics. After 20 pages on Chapter 1, Philoponus devotes the remaining 66 pages to Aristotle's objections to two major Presocratic thinkers, Parmenides and Melissus. Aristotle included these thinkers as an aside, because they were not engaged in physics, but in questioning the very basis of physics. Philoponus investigates Aristotle's claims about the relation between a science and its axioms, explores alternative ways of formalising Aristotle's refutation of Eleatic monism and provides a sustained critique of Aristotle's analysis of the Eleatics' purported mistakes about unity and being.
