“I recommend this volume to all those with any interest in the concepts treated in the philosophy of action.” (Philosophy in Review, 1 December 2012)
"The collection is a critically important resource for scholars of the philosophy of action. The overall clarity of the entries, moreover, also makes it accessible as a resource for undergraduate and graduate students working in the area. Highly recommended. Upper-level undergraduates through faculty/researchers." (Choice, 1 March 2011)
"O'Connor and Sandis have edited a wide-ranging, accessible collection that will be an invaluable resource for anyone interested in the philosophy of action. Highly recommended." (Metapsychology Online Reviews, 12 April 2011)
"This companion is a welcome addition to philosophical literature, asserting a kind of sovereignty over a territory often visited in philosophical discussions of mind, ethics and metaphysics, but not given any kind of independence. In asking us to regard the human action not merely as a part of other areas of philosophical investigation, but as one worth considering on its own, this Companion should be applauded. One particularly good feature of the book is that all the entries are substantial: while one can treat it as a reference work, readers will find it rewarding to read straight through the entries in a given section."
