Double-Effect Reasoning: Doing Good and Avoiding Evil

T. A. Cavanaugh is Professor and Chair of Philosophy, University of San Francisco.

"Thomas Cavanugh has written a splendid book. he provides a succinct yet comprehensive survey of the history of double-effect reasoning (DER) but also a thoroughly engages the present debate and advances one's understanding with original insights. His writing is philosophically rigorous, yet always clear and comprehensible, and it should be accessible to a wide audience. ... If there is such a thing as a page-turner in ethics, this is it. I thoroughly enjoyed reading it."
--Studies in Christian Ethics

"Thomas Cavanaugh has written a fine book and the problem he is struggling with ought to be of great concern to the military profession."
--Journal of Military Ethics

"In this work [Cavanaugh] gives a magisterial account of the history, the philosophical basis, and the continued relevance of double-effect reasoning (DER) in ethics. ... I take the text to be without peer in its engagement with teh current debate, and its clarity in the presentation of DER's claims and historical roots."
--International Philosophical Quarterly

"Cavanaugh's pedagogical overview and critical engagement with the long history of DER's development provides an illuminating guide to the theoretical dimensions of this important mode of moral reasoning."
--American Catholic Philosophical Quarterly
