Definition talk:Set

I think it should be also mentioned here that set is distributive (not collective) aggregation of objects (this might be reason for avoiding naming set a "collection" :p). Example: Mars is an element of set of planets but any element of this planet, e.g. rock lying on it, is not an element of the set of planets anymore (distributivity); body is an element of car parts and windshield is an element of the body, so it is an element of the car (collectivity). I belive that this would give proper intuition for the notion. joel talk 19:16, 29 December 2012 (UTC)


 * Just sounds like overcomplication to me. Never seen these terms used in anything I've encountered. --prime mover (talk) 21:44, 29 December 2012 (UTC)


 * I've noticed that it is hard to find a decent source about the subject: aim of this distinction is to differentiate distributive set theory (classical) from collective set theory (mereology) of Leśniewski (check also Standford Encyclopedia of Philosophy and Philosophy of Stanisław Leśniewski). if none is introduced (and unknown) then it might be profitable to tell in some words which meaning of the set is intended. All in all it might be, as you said, too complicated—I generally do not insist to incorporate it into this article, all things are ultimately settled by axioms, but thought it would be helpful in some way to give a proper intuition (maybe it'd be enough to say that "belonging relation is not transitive"). joel talk 09:23, 30 December 2012 (UTC)


 * I don't know about the rest of you out there, but I would fight tooth-and-nail against extending ProofWiki to encompass "philosophy". There is absolutely no point at all in adding "belonging relation is not transitive" to this page. Please try and get to grips with the philosophy of this site, it is a dictionary NOT an encyclopedia. --prime mover (talk) 10:32, 30 December 2012 (UTC)
