In many philosophical contexts it is important to keep *sets* (abstract
non-temporal entities) (07)
[Chris Partridge] I believe David Lewis (In Plurarity of Worlds) rails
against this interpretation. He sees sets (especially small finite sets
whose members are not scattered) as clearly concrete, with an obvious
spatio-temporal location. Can I put that on people's reading lists :-). (08)
whose members are spatiotemporal entities
distinct from the *aggregate* (Mario Bunge) or the *collection* (Peter
Simons) of the same spatiotemporal entities. However, in many contexts
it doesn't matter whether one talks of sets or of
aggregates/collections. I guess Pat Hayes is working within the latter
kind of contexts; it is a pity that it misleads him into thinking that
"what you can represent as a set, is a set". (09)
