This article is in six main sections. Section I provides an account of what is involved in holding any agent responsible, identifying three necessary conditions for fitness to be held responsible. In Sections II-IV, the author argues that corporate agents often meet these conditions and so are fit to be held responsible. Section V shows why there is a point in holding corporate agents responsible, side by side with the individual agents who act in their name. The article concludes with a brief discussion of how far the lesson defended applies to looser collections of individuals, such as national and religious traditions, and not just to properly corporate agents.
