Abstract

With this collection of translations of Aristotle’s main works, accompanied by commentaries, General Editors J. L. Ackrill and Lindon Judson have made another step forward. In book 8 of the Physics, Aristotle develops his doctrine of the First Unmoved Mover, the efficient cause of all movements and process in the world. It is commonly agreed upon that this book constitutes a unit with books 2 to 6. It is later than the other books and the greater part of the De caelo.
