Abstract

The task of responding to five serious and thoughtful papers is not an easy one. Although there is some overlap among them, each paper makes its own distinctive points. What we have decided to do is to identify the major concerns expressed by each author and then to respond to those concerns as best we can. The level of specificity that is possible in the identification of concerns is virtually infinite. The concerns that we have identified we regard as either important in their own right or common across the five papers that were invited. Following each point is our response.
