Of course this is a clearretreat from what you've just said before, where you said that no pathis actually infinite, anyhow. Possibly you are referring to potentialinfinity when you say infinite path of nodes. But by argument ofpotential infinity you cannot have something called "infinite" path ofnodes, all what you can have is 'finite' paths. And again clearly whatyou are addressing is something quite different from what Cantor isspeaking about. Cantor is speaking about Reals that are represented byACTUALLY INFINITE paths. And so far nobody have succeeded todemonstrate any contradiction involved with this concept. It isremains a standing possibility that mathematics must deal with.Zuhair
