In Aristotle's teleological view of the world, natural things come to be and are present for the sake of some function or end (for example, wings are present in birds for the sake of flying). Whereas much of recent scholarship has focused on uncovering the (meta-)physical underpinnings of Aristotle's teleology and its contrasts with his notions of chance and necessity, this book examines Aristotle's use of the theory of natural teleology in producing explanations of natural phenomena. Close analyses of Aristotle's natural treatises and his Posterior Analytics show what methods are used for the discovery of functions or ends that figure in teleological explanations, how these explanations are structured, and how well they work in making sense of phenomena. The book will be valuable for all who are interested in Aristotle's natural science, his philosophy of science, and his biology.

"....the account of the syllogistic structure of teleological explanations presented in the sixth chapter is one to be reckoned with. The preceding chapters can be recommended unconditionally. They offer a clear and wonderfully helpful schematic presentation of the explanatory and methodological structure of the various teleological explanations offered in the physical treatises; future readers of these treatises would be well advised to make ample use of them."
--Owen Goldin, Marquette University, Bryn Mawr Classical Review

"....a rich account of how Aristotle thinks teleological causation operates in nature and how final causes are to be integrated into a more comprehensive picture of explanation in natural science. Explanation and Teleology in Aristotle's Science of Nature is an important contribution to scholarship on Aristotle's teleology.... her book has added significantly to the debate and must be engaged with by anyone wishing to tackle the subject from this point forward.... this book will be of interest to a much broader audience. While the reader is assumed to have some familiarity with Aristotle's philosophy of nature, Leunissen's discussion is quite accessible. Most technical concepts are explained and illustrated with examples, and she offers an abundance of textual evidence in support of her claims.... there is certainly no shortage of philosophically engaging ideas in her book."
--Devin Henry, University of Western Ontario, Notre Dame Philosophical Reviews

"... this book provides an important contribution to the studies of Aristotle's science of nature and present a set of ideas in a very clear manner. This will be the point book for all research on the teleology in Aristotle's science of nature."
