1 I wish to thank E. E. Pender for sparing time to discuss my thoughts on this passage with me when they were very ill-formed and for encouraging me to try to sort them out. I also thank N. Fox, S. Stern-Gillet, C. Tipper, and P. Vassilopoulou for a number of useful suggestions and other help; and CQ’s anonymous referee, whose comments on the first version of this note compelled me to make some important points more clearly than I had done. The responsibility for what appears here remains my own, of course.
