Doctrine of Double Effect, The

This anthology of philosophical essays, gathered from numerous sources, provides a convenient, in-depth introduction to the Doctrine of Double Effect. A number of important philosophers and intellectual perspectives are represented in what constitutes a debate over the doctrine and the various concerns it raises. Philosophers represented in these readings include Joseph M. Boyle, Jr., Warren Quinn, G. E. M. Anscombe, Thomas Nagel, Phillippa Foot, Jonathan Bennett, Nancy Davis, Donald Marquis, and many others.

The Doctrine of Double Effect is a principle of reasoning well known to moral philosophers. The standard formulation of the doctrine states that it is "licit to posit a cause which is either good or indifferent from which there follows a twofold effect, one good, the other evil, if a proportionally grave reason is present, and if the end of the agent is honorable."

According to this doctrine, an effect that would be considered morally wrong if it were the intentional outcome of an act could be morally permissible if it were the unintended effect of that act, even if it had been foreseen. As a method of drawing moral distinctions between the intentional and unintentional production of evil, the doctrine has had a long history. It has often been employed, for example, in debates about "just war" and the kinds of acts that are permissible in war.

The first section of this collection offers an introduction to the doctrine, its purpose, its claims, and the issues it raises for moral philosophers. Sections two and three take the form of a debate by several influential thinkers about the validity of the doctrine and the many problems surrounding it. The authors in section two defend the doctrine; those in section three oppose it. Sections four and five focus on applications, concrete and theoretical, of the doctrine, showing its possible uses and misuses.

This book will be valuable to teachers and students of philosophy as well as others interested in a clear understanding of this controversial doctrine.
