The author prefaces the afterword in the following manner: “Professors Goldsmith and Posner have given an insightful reply to my Article. It has been a pleasure to engage in a discussion of these issues with respected colleagues via this exchange of writings, and I am grateful to the Journal for providing the opportunity to do so. Most of the positions I have taken are already adequately discussed in the body of the Article, and this afterword is not intended to summarize all of the arguments made there. However, I wanted to address some of the points Professors Goldsmith and Posner make in their reply. I have organized this afterword using their numbering.”
