Abstract
Of this batch of books 1 the one I found most compelling reading was Sarah Waterlow's Nature, Change and Agency . This work is an intense meditative commentary on the most important portions of the Physics; it probes beneath the text of Aristotle's loosely organized treatise to exhibit its deep structure. Waterlow attempts to show how Aristotle's apparently independent and self-contained discussions in Books I, II, III-IV and VIII all rest on a single notion, viz. that the world consists of natural substances, understood as things engaged each in a unitary pattern of change whose source and determining plan is within themselves
