Sorry I missed Sunday's meeting at Gaya's -- was driving back home after visiting a friend in MA where the autumn leaves were putting on their magical display in the chilly chilly air (we ate a lot of beans!).
A couple straggling thoughts: a consideration of naturalness also has a fractal pattern -- at almost any resolution, in any domain, nature plays out in interesting ways -- another one of the benefits (and difficulties!) in discussing naturalness. Looking back at the comments from last week, maybe another theme we might have been trying to get at is the sense that the distinction between interior and external is softer than we tend to think.
