Abstract:

I think seminars are of two kinds - there are those which confirm one's prejudices, and those which enable one to re-organize and rearrange one's prejudices, and I would say that this is certainly of the second kind - that I have rearranged all of my prejudices and dusted them up a little. Certainly, being serious, this seminar has made me think, and I have found it very valuable. I'd like today to speak under four headings, which I hope will do justice to most, though not all, of the topics that we've discussed. I'm not going to refer back to all of the papers in the seminar, by any means.
