These two interesting papers raise a number of important issues. I will limit myself, however, to drawing out some of the recurring questions, in order to keep myself from wandering too much down fascinating side alleys.
I cannot resist, however, beginning with what sounds like a digression. There is a lot of misunderstanding of what I was trying to say, especially in Braybrooke's paper. My author's reflex is to blame my readers. But a moment's quiet thought makes me aware of how far from totally clear I was. More than that, some of what is at issue between us is precisely the grid within which these questions should be debated. I am dissatisfied with the accepted way of putting some of these questions, and I want to propose new terms. It was inevitable that misunderstandings arise in these circumstances.
