Simplicius: On Aristotle On the Heavens 1.1-4


Book Description

In chapter 1 of On the Heavens Aristotle defines body, and then notoriously ruptures dynamics by introducing a fifth element, beyond Plato's four, to explain the rotation of the heavens, which, like nearly all Greeks, Aristotle took to be real, not apparent. Even a member of his school, Xenarchus, we are told, rejected his fifth element. The Neoplatonist Simplicius seeks to harmonise Plato and Aristotle. Plato, he says, thought that the heavens were composed of all four elements but with the purest kind of fire, namely light, predominating. That Plato would not mind this being called a fifth element is shown by his associating with the heavens the fifth of the five convex regular solids recognised by geometry. Simplicius follows Aristotle's view that one of the lower elements, fire, also rotates, as shown by the behaviour of comets. But such motion, though natural for the fifth elements, is super-natural for fire. Simplicius reveals that the Aristotelian Alexander of Aphrodisias recognised the need to supplement Aristotle and account for the annual approach and retreat of planets by means of Ptolemy's epicycles or eccentrics. Aristotle's philosopher-god is turned by Simplicius, following his teacher Ammonius, into a creator-god, like Plato's. But the creation is beginningless, as shown by the argument that, if you try to imagine a time when it began, you cannot answer the question, 'Why not sooner?' In explaining the creation, Simplicius follows the Neoplatonist expansion of Aristotle's four 'causes' to six. The final result gives us a cosmology very considerably removed from Aristotle's.




On the Heavens


Book Description

On the Heavens (Greek: Περὶ οὐρανοῦ, Latin: De Caelo or De Caelo et Mundo) is Aristotle’s chief cosmological treatise: written in 350 BC it contains his astronomical theory and his ideas on the concrete workings of the terrestrial world. It should not be confused with the spurious work On the Universe (De mundo, also known as On the Cosmos).




Simplicius: On Aristotle On the Heavens 1.2-3


Book Description

One of the arguments in Aristotle's On the Heavens propounds that the world neither came to be nor will perish. This volume contains the pagan Neoplatonist Simplicius of Cilicia's commentary on the first part of this this important work. The commentary is notable and unusual because Simplicius includes in his discussion lengthy representations of the Christian John Philoponus' criticisms of Aristotle along with his own, frequently sarcastic, responses. This is the first complete translation into a modern language of Simplicius' commentary, and is accompanied by a detailed introduction, extensive explanatory notes and a bibliography.




Simplicius: On Aristotle On the Heavens 1.3-4


Book Description

This is the first English translation of Simplicius' responses to Philoponus' Against Aristotle on the Eternity of the World. The commentary is published in two volumes: Ian Mueller's previous book in the series, Simplicius: On Aristotle On the Heavens 1.2-3, and this book on 1.3-4. Philoponus, the Christian, had argued that Aristotle's arguments do not succeed. For all they show to the contrary, Christianity may be right that the heavens were brought into existence by the only divine being and one moment in time, and will cease to exist at some future moment. Simplicius upholds the pagan view that the heavens are eternal and divine, and argues that their eternity is shown by their astronomical movements coupled with certain principles of Aristotle. The English translation in this volume is accompanied by a detailed introduction, extensive commentary notes and a bibliography.




Simplicius: On Aristotle On the Heavens 2.1-9


Book Description

Aristotle believed that the outermost stars are carried round us on a transparent sphere. There are directions in the universe and a preferred direction of rotation. The sun moon and planets are carried on different revolving spheres. The spheres and celestial bodies are composed of an everlasting fifth element, which has none of the ordinary contrary properties like heat and cold which could destroy it, but only the facility for uniform rotation. But this creates problems as to how the heavenly bodies create light, and, in the case of the sun, heat. The value of Simplicius' commentary on On the Heavens 2,1-9 lies both in its preservation of the lost comments of Alexander and in Simplicius' controversy with him. The two of them discuss not only the problem mentioned, but also whether soul and nature move the spheres as two distinct forces or as one. Alexander appears to have simplified Aristotle's system of 55 spheres down to seven, and some hints may be gleaned as to whether, simplifying further, he thinks there are seven ultimate movers, or only one.




Simplicius: On Aristotle On the Heavens 1.5-9


Book Description

Aristotle argues in On the Heavens 1.5-7 that there can be no infinitely large body, and in 1.8-9 that there cannot be more than one physical world. As a corollary in 1.9, he infers that there is no place, vacuum or time beyond the outermost stars. As one argument in favour of a single world, he argues that his four elements: earth, air, fire and water, have only one natural destination apiece. Moreover they accelerate as they approach it and acceleration cannot be unlimited. However, the Neoplatonist Simplicius, who wrote the commentary in the sixth century AD (here translated into English), tells us that this whole world view was to be rejected by Strato, the third head of Aristotle's school. At the same time, he tells us the different theories of acceleration in Greek philosophy.




Simplicius: On Aristotle Categories 1-4


Book Description

Simplicius' commentary on Aristotle's Categories is the most comprehensive philosophical critique of the work ever written, representing 600 years of criticism. In his Categories, Aristotle divides what exists in the sensible world into ten categories of Substance, Quantity, Relative, Quality and so on. Simplicius starts with a survey of previous commentators, and an introductory set of questions about Aristotle's philosophy and about the Categories in particular. The commentator, he says, needs to present Plato and Aristotle as in harmony on most things. Why are precisely ten categories named, given that Plato did with fewer distinctions? We have a survey of views on this. And where in the scheme of categories would one fit a quality that defines a substance - under substance or under quality? In his own commentary, Porphyry suggested classifying a defining quality as something distinct, a substantial quality, but others objected that this would constitute an eleventh. The most persistent question dealt with here is whether the categories classify words, concepts, or things.




Aëtiana


Book Description

Ancient doxography, particularly as distilled in the work on problems of physics by Aëtius, is a vital source for our knowledge of early Greek philosophy up to the first century BCE. But its purpose and method, and also its wider intellectual context, are by no means easy to understand. The present volume contains 19 essays written between 1989 and 2009 in which the authors grapple with various aspects of the doxographical tradition and its main representatives. The essays examine the origins of the doxographical method in the work of Aristotle and Theophrastus and also provide valuable insights into the works of other authors such as Epicurus, Chrysippus, Lucretius, Cicero, Philo of Alexandria and Seneca. The collection can be read as a companion collection to the two earlier volumes of Aëtiana published by the two authors in this series (1997, 2009).




Eternal Life and Human Happiness in Heaven


Book Description

Eternal Life and Human Happiness in Heaven treats four apparent problems concerning eternal life in order to clarify our thinking about perfect human happiness in heaven. The teachings of St. Thomas Aquinas provide the basis for solutions to these four problems about eternal life insofar as his teachings call into question common contemporary theological or philosophical presuppositions about God, human persons, and the nature of heaven itself. Indeed, these Thomistic solutions often require us to think very differently from our contemporaries. But thinking differently with St. Thomas is worth it: for the Thomistic solutions to these apparent problems are more satisfying, on both theological and philosophical grounds, than a number of contemporary theological and philosophical approaches. Christopher Brown deploys his argument in four sections. The first section lays out, in three chapters, four apparent problems concerning eternal life—Is heaven a mystical or social reality? Is heaven other-worldly or this-worldly? Is heaven static or dynamic? Won’t human persons eventually get bored in heaven? Brown then explains how and why some important contemporary Christian theologians and philosophers resolve these problems, and notes serious problems with each of these contemporary solutions. The second section explains, in five chapters, St. Thomas’ significant distinction between the essential reward of the saints in heaven and the accidental reward, and treats in detail his account of that in which the essential reward consists, namely, the beatific vision and the proper accidents of the vision (delight, joy, and charity). The third section treats, in five chapters, St. Thomas’ views on the multifaceted accidental reward in heaven, where the accidental reward includes, among other things, glorified human embodiment, participation in the communion of the saints, and the joy experienced by the saints in sensing God’s “new heavens and new earth.” Finally, section four argues, in four chapters, that St. Thomas’ views allow for powerful solutions to the four apparent problems about eternal life examined in the first section. These solutions are powerful because, not only are they consistent with authoritative, Catholic Christian Tradition, but they do not raise any of the significant theological or philosophical problems that attend the contemporary theological and philosophical solutions examined in the first section.
