Abstract

The paper tries to locate the moral limits of weapons research, an issue that comes about because weapons harm and unjustified harms are wrong.Doing research does not itself harm, so first it is shown that a means principle holds. Weapons research then needs to be justified, and two ways to do this arecanvassed, historical and a historical. The former takes account of the context in which the work is done and the circumstances the products used. It is arguedthat there can only be historical justifications, given that there are no inherently defensive, deterrent or humane weapons. However, weapons designs live onbeyond the circumstances in which they were created, and even if these amount to ‘just war’ there can be an assurance that the products will not be used unjustlyin the future. A radical solution is suggested for this problem.
