 selfcontained sets
Michelle,
I don't think that seeds contain themselves, they contain information that lead to their formation. I think Dustin's example was a sound one: a cookie contains ingredients (flour, sugar, eggs and butter-and hopefully chocolate!) but the ingredients of a cookie do not contain a cookie. A set of things (whatever those things are) may or may not contain itself (a bag of bags, etc) but does the set of all sets contain itself? |
