A substantially revised and supplemented edition of the collected volume originally published, by Duckworth, in 1987.

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 the first book-length study in English of the interpretative and philosophical approach of the commentaries of Simplicius of Cilicia (c. AD 530). Simplicius' work, marked by doctrinal complexity and scholarship, is unusually self-conscious, learned and rich in its sources, and he is therefore one of those rare authors who is of interest to ancient philosophers, historians and classicists alike. Here, Han Baltussen argues that our understanding of Simplicius' methodology will be greatly enhanced if we study how his scholarly approach impacts on his philosophical exegesis. His commentaries are placed in their intellectual context and several case studies shed light on his critical treatment of earlier philosophers and his often polemical use of previous commentaries. "Philosophy and Exegesis in Simplicius" not only clarifies the objectives, pre-suppositions and impact of Simplicius' work, but also illustrates how, as a competent philosopher explicating Aristotelian and Platonic ideas, he continues and develops a method that pursues philosophy by way of exegetical engagement with earlier thinkers and commentators. The investigation opens up connections with broader issues, such as the reception of Presocratic philosophy within the commentary tradition, the nature and purpose of his commentaries, and the demise of pagan philosophy.

Science in Byzantium has rarely been systematically explored. A first of its kind, this collection of essays highlights the disciplines, achievements, and contexts of Byzantine science across the eleven centuries of the Byzantine empire. After an introduction on science in Byzantium and the 21st century, and a study of Christianization and the teaching of science in Byzantium, it offers a comprehensive and up-to-date survey of the scientific disciplines cultivated in Byzantium, from the exact to the natural sciences, medicine, polemology, and the occult sciences. The volume showcases the diversity and vivacity of the varied scientific endeavours in the Byzantine world across its long history, and aims to bring the field into broader conversations within Byzantine studies, medieval studies, and history of science. Contributors are Fabio Acerbi, Anne-Laurence Caudano, Gonzalo Andreotti Cruz, Katerina Ierodiakonou, Herve Inglebert, Stavros Lazaris, Divna Manolova, Maria K. Papathanassiou, Inmaculada Pérez Martín, Thomas Salmon, Ioannis Telelis, Anne Tihon, Alain Touwaide, Arnaud Zucker.

Examines Aristotle's vast influence upon the medieval Arabic philosophical tradition and includes contributions from every discipline within his corpus.

The first Argument, which survives in Arabic, is also included and makes this the only complete edition of On the Eternity of the World since antiquity.".

This book describes how natural philosophy and exact mathematical sciences joined together to make the Scientific Revolution possible.

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.
