Abstract

1. Introduction

Our three commentators raise such a host of deep and interesting issues that we cannot hope to answer them all within the time and space at our disposal. To begin with, we would like to thank them for pushing us to articulate the reasons for our arguments more clearly, and for getting us to spell out a number of assumptions and intermediate argumentative steps that we did not make sufficiently clear or explicit in our original article. We will deal with the three commentators one by one, limiting ourselves to a few key points.
