I am sorry not to have been more active with the reading group but my return trip (25 hours door to door from Santa Fe to Lancester Hotel House in the UK) added to the jetlag was difficult for me; in addition I had to take care of many details which were waiting for my return. I remotely follow your mails.

It stands betwqeen "nomical emergence" (emergence in name only), which arises because the terms by which tha whole is described are incommensurate with the terms by which its parts are described, and "strong emergence", which is said to have irreducible causal powers but which Bedau thinks is "scientifically irrelevant". A property of a whole is weakly emergent if it cannot be derived from the properties of the parts except by simulation. For Friam list members, Bedau's chapter may be the most interesting so far because it makes extensive use of examples from the complexity literature. One problem we readers will have is deciding whether the designation "weak" refers to some distinct kinds of events in the world (and is therefore ontological) or whether it refers to the state of our explanatory skills (in which case it is epistemological). The distinction is important because we might expect ontological distinctions to survive indefinitely, whereas epistemological ones should be eliminated with the progress of science. Bedau seems to think his distinction is ontological, but his argument for that position seems a bit shabby. As before, we invite Friam readers to read along with us and to comment on this thread only if they have done the reading mentioned in the subject heading. Take care, everybody, Nick Nicholas S.
