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 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.

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.

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.
