  1. This isnt true - describing something does not give it identity or existence. I can talk intelligibly about the pink unicorn in my uncle's garden without presupposing that there is actually such a thing existing. Since identity necessarily entails existence ("to be a thing is to be"), it would follow from your argument that anything we can describe actually exists. jrshep - I'm going to bed, I'll reply to your post tomorrow.
  2. Why does this get included in the body of a post whenever I do a quote? (xxxxx is a number). edit: eg when quoting a random post I get [.quote=stephen_speicher,Aug 9 2004, 08:21 PM]Sorry to start another thread but starting threads is all I can do. Since I switched back to an old skin I cannot reply to any posts. Anyone have a clue as to how to reset things back to the new default skin for the new update GC did?

  3. Not really, its giving it a description. A linguistic description isnt a metaphysical 'identity' however, since I can desribe objects that have no identity (eg in my last post "something which exhibits random behavior")
  4. Again, use isnt mention. However rather than develop this I'll use a different example since its in danger of drifting offtopic; if someone claims that an object exists which exhibits genuinelly random behavior, would this presuppose the law of identity?
  5. Huh? You seem to be confusing use and mention; they would be using the phrase "subatomic particles" to refer to something which they beleive has no definite identity (technically they wouldnt be referring to an actual encountered object, but to a hypothesised/constructed one).
  6. Again, the negation of 'everything has identity' is not 'nothing has identity'. To take a concrete example, if someone were to say that (for instance) subatomic particles have no definite identity, they would not be presupposing the law of identity in doing so.
  7. How so? If I were to say "Existence isnt identity and not everything that exists has identity", in what way would I be presupposing it?
  8. Well books are different - reading a physical book is a lot more comfortable than reading a large amount of text on a computer monitor, and then you have the portability issue as well. I doubt that even portable ebook readers would be as nice to read as an actual paper book, although I haven't used one. Also, theres the locatability factor - its a lot easier to find a physical copy of an obscure(ish) book than an e-book version. Although having said that, perhaps something like electronic ink will replace paper books in the future, for popular stuff anyway. With music though, the CD is completely redundant (for me anyway). In order to use a CD have to first rip it onto my computer and then download the songs onto my portable mp3 player, after which I can basically throw the CD away (although I'll generally keep it in case I ever reformat). It's quite a hassle, and downloading songs directly is a lot easier. I think a lot of others feel the same, which is why legal downloading services such as iTunes have become so popular.
  9. Steven, I thought more about what it was I was trying to say and realised that I was mistaken. I was subconsiously thinking in terms of a certain model of the universe, even though I actually knew that said model wasnt technically correct. I was essentially viewing the universe as consisting of lots of 'space', in which certain things existed (ie space was a primary). Saying that 'nothing' exists in a given region just meant that there would be no material things occupying that region of space (ie it would be completely empty). Obviously this presupposes a certain view of space which certainly can't be assumed a priori, and (as far as I know) is even invalidated by modern physics.
  10. That's not really correct - the denial of "everthing that exists has identity" isnt "everything that exists doesnt havent identity", it is "at least one thing exists without identity". You can deny the law of identity without presupposing it and theres not really any way to demonstrate or prove it to a person who doubts it's truth. If someone refuses to accept it then you've reached a point where you can go no further, and it's probably best not to continue the argument because you can't really reduce things to anything more fundamental. This isnt really a denial of identity. It's possible for 2 sides to be partially right and partially wrong, or to both be correct by different standards. For instance, both 'liberals' and 'conservatives' are partially correct ('conservatives' when they champion the freemarket, 'liberals' when they oppose state religion). It would only be a denial of identity if both sides were in direct contradiction and using the same standard of validation.
  11. Not had time to post much recently, but just wanted to say I discovered this on Diana Mertz's site and found it quite interesting.
  12. Yeah, I agree that this is the best way to approach induction ('probabilistic truth until cause has been discovered'), I was just wondering how you would handle a few concrete cases. Thanks.
  13. To put it another way, assume we have a region of space. We systematically remove every atom from this region (using our super powerful futuristic microscopes and atom removers) until there is no matter we know of which is left in this space. Now, there seems to be only 4 possibilities: 1) This space is empty. 2) We can never remove all matter from this space, there will always be some matter which eludes us. 3) There is something in this space that is not matter - it is immaterial and (possibly) ineffable. 4) There is plenum in this space (this isnt really a seperate option since plenum would have to either be matter or not be matter, and this would hence correspond to either 2) or 3). I'm only including it for the sake of completeness. I suppose that "there is plenum but we do not know whether plenum is matter or not matter - that is for science to decide" would be this option though.). I am claiming 1). Which one does your conception of plenum correspond to? I'm not even arguing with you at the moment, I'm trying to clarify what youre actually saying because I am honestly unsure.
