This book offers a new edition, with English translation and commentary, of the Kitab al-Madhal, which opens Avicenna's (d. 1037) most comprehensive summa of Peripatetic philosophy, namely the Kitab al-Sifa'. For the first time, the text is established together with a stemma codicum showing the genealogical relations among 34 manuscripts, the twelfth-century Latin translation, and the literal quotations by Avicenna's first and second-generation students. In this book, Avicenna's reappraisal of Porphyry's Isagoge is examined from both a historical and a philosophical point of view. The key-features of Avicenna's theory of predicables are analyzed in the General Introduction and in the Commentary both in their own right and against the background of the Greek and Arabic exegetical tradition. Readers shall find in this book the first systematic study of the Madhal which, in addition to being the only logical work of the Sifa' ever transmitted in its entirety both in Arabic and in Latin, is crucial for understanding Avicenna's conception of universal predicables at the crossroads between logic and metaphysics.

"Avicenna's Physics" is the very first volume that he wrote when he began his monumental encyclopedia of science and philosophy, "The Healing". Avicenna's reasons for beginning with "Physics" are numerous: it offers up the principles needed to understand such special natural sciences as psychology; it sets up many of the problems that take center stage in his Metaphysics; and it provides concrete examples of many of the abstract analytical tools that he would develop later in "Logic". While "Avicenna's Physics" roughly follows the thought of "Aristotle's Physics", with its emphasis on natural causes, the nature of motion, and the conditions necessary for motion, the work is hardly derivative. It represents arguably the most brilliant mind of late antiquity grappling with and rethinking the entire tradition of natural philosophy inherited from the Greeks as well as the physical thought of Muslim speculative theologians. As such, "Physics" is essential reading for anyone interested in understanding Avicenna's complete philosophical system, the history of science, or the history of ideas.
