Many thanks to all the nice people who made the Joint Sessions so very pleasant (cf. Jonny's review). My talk went well enough (e.g. I didn't faint), although the talks I sat through were more accessible and interesting, as were all the plenary speakers. The best bit was Kit Fine likening David Lewis to Thales (which I sympathise with). Lewis said that to question set theory would be silly, yet his basic supposition was that there are no Laws of Nature (which is impossible, whereas set-theoretical sciences are just like Ptolomaic astronomy).
