This thread has become quite strange.
QUOTE (DaleLewill @ Jan 18 2007, 02:04 AM)I think it basically means that:How can you prove that you exist? Well the fact that you think proves it. Your existence is proven by your own thoughts - philosophically, no other human does truly exist nor does material I guess. You can only prove to yourself that you truly exist.Aye, very well explained. However, I’ve never really thought it makes much sense because from the viewpoint of an outsider, Descartes simply assigns a random property to something he hasn’t proved exists, then argues in a circle — using that property to ‘prove’ his existence!To use an analogy, I’d equate that with my ‘proving’ ice exists by assigning it a random property (ice = cold!) and then saying: ‘Because ice = cold, therefore ice must exist”. Erm… :blink: 
Love Spider–waffle’s spped run. One of the gaming mags around here featured it on a disc they included quite a while back. I wish I could find it again — otherwise I have to resort to Youtube. Love the way he flies (impact boost + bunnyhopping, to use HL2DQ terminology 
) from one end of the Blast Pit fuel & oxygen activation sections to the other.
