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.
"This text by Philoponus rejects accounts of soul or, as we would say, of mind, that define it as being in motion or in cognitive or 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, but, probably following Ammonius, he takes Plato's apparently physicalist account of the soul in the Timeus as symbolic; Aristotle's criticism only concerns literalists. What we would call the mind-body relation is the subject of Chapter 4. In chapter 5, Philoponus endorses Aristotle's rejection of the idea that the soul is particles and of Empedocles's idea that the soul must be made of all four elements in order to know what is made of the same elements."--BOOK JACKET.
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.
This study provides the first full discussion of Philoponus' excursus on matter in contra Proclum XI. 1-8 which sets out the innovative definition of prime matter as three-dimensional extension. The author argues that Philoponus' definition was motivated primarily by philosophical problems in Neoplatonism. Philoponus employs the explanation of growth, the interpretation of Aristotle's category theory and the notions of formlessness and potentiality to substantiate his definition. To conclude, the book offers an assessment of the significance of Philoponus' innovation. It is demonstrated for the first time that Plotinus' view of matter exerted considerable influence on both Philoponus and Simplicius. Moreover, the structure of Syrianus' and Proclus' metaphysics prepared the way for Philoponus' account of prime matter.
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.
This text by Philoponus, the sixth-century commentator on Aristotle, is notable for its informative introduction to psychology, which tells us the views of Philoponus, of his teacher and of later Neoplatonists on our psychological capacities and on mind-body relations. There is an unusual account of how reason can infer a universally valid conclusion from a single instance, and there are inherited views on the roles of intellect and perception in concept formation, and on the human ability to make reasoned decisions, celebrated by Aristotle, but here downgraded. Philoponus attacks Galen's view that psychological capacities follow, or result from, bodily chemistry; they merely supervene on that and can be counteracted. He has benefited from Galen's knowledge of the brain and nerves, but also propounds the Neoplatonist belief in tenuous bodies which after death support our irrational souls temporarily, or our reason eternally.
The first five chapters of Aristotle's De Generatione et Corruptione distinguish creation and destruction from mere qualitative change and from growth. They include a fascinating debate about the atomists' analysis of creation and destruction as due to the rearrangement of indivisible atoms. Aristotle's rival belief in the infinite divisibility of matter is explained and defended against the atomists' powerful attack on infinite divisibility. But what inspired Philoponus most in his commentary 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. Philoponus draws out a brief remark of Aristotle's to show that cause need not be like effect. For example, what makes something hard may be cold, not hard. This goes against a persistent philosophical prejudice, but Philoponus makes it plausible that Aristotle recognized this truth. These topics of identity over time and the principles of causation are still matters of intense discussion.
R. J. Hankinson traces the history of ancient Greek thinking about causation and explanation, from its earliest beginnings through more than a thousand years to the middle of the first millennium of the Christian era. He examines ways in which the Ancient Greeks dealt with questions about how and why things happen as and when they do, about the basic constitution and structure of things, about function and purpose, laws of nature, chance, coincidence, and responsibility.
