For scholars approaching Aristotle's biological treatises for the first time, the value of this book is found in the comprehensive way of understanding Aristotle's work that emerges from the collection of Gotthelf's best contributions. For scholars already familiar with Gotthelf's work, the value comes in the chapters published for the first time and from the fact that this work collects together the various parts of Gotthelf's interpretation in the way Gotthelf himself thinks these parts fit together. That the book includes an impressive list of references and indexes (locorum, names, and subjects) further increases its value as a reference for those engaging with Aristotleâs biological treatises.
