I am impressed at the range and perceptiveness of these papers, and grateful both for the interest the authors show in my work, and the opportunity to try to restate my ideas. These 14 papers offer a challenge that is certainly worth more than the few pages I can devote to them here. In fact, they make me think that perhaps I should expand the several-times-too-many pages I initially wrote on reflection of them to a book in its own right. We’ll see! Meanwhile, my thanks again both to Grant Brown, who originated the idea for this Festschrift project and did much initial work on it, and to Malcolm Murray for his wonderfully efficient job at bringing it to a successful conclusion – as well as to Ashgate for bringing it to the attention of, I hope, a wider interested public.
