That WM's particular form of logic is rife with contradictions. For every 0 node there is a path in WM's set NOT containing it, and for every path in WM's set there is a node NOT contained in it, so why does WM insist that there is a path in your set containing every node?

Only WM claims that. Mathematicians claim that in ZFC there is a set of all nodes each represented by a finite. possibly empty, binary string of, say, zeroes and ones, and a set of all paths, each path being a function from N to {0,1}. Two such paths coincide on some initial string, the string of nodes preceding the first node at which they differ. Any two paths determine a > This would...

It is not so much what WM does not know than hurts him, and his students, it's what he "knows" that ain't so, and then tries to teach to his poor captive students.

That is potential infinity. For every node there is a path surpassing it For every path there is a node surpassing it. There is no "all nodes" and no "all paths". Actual infinity infinity or set theory, what is the same, claim that there is a path containing all nodes (namely the path 0.000...) and that the union of all paths 0.111... 0.0111... 0.00111... .... contains the path 0.000... but that there is no single path of the list containing all nodes of 0.000... That is simply impossible. The union of paths of the list contains exactly as many nodes of 0.000... as one of those paths to be unioned. If none of them contains all nodes of 0.000..., then even infinitely many will not accomplish that goal. The union of paths cannot result in more than any contributing path. The union can be potentially infinite. A union of finite paths cannot yield a path of fixed length the lengths of which surpasses every contributing path. Regards, WM Regards, WM

While I can guess what you mean by saying "For every node there is a path surpassing it", I have no idea what you might mean by "For every path there is a node surpassing it". > There is no "all nodes" and no "all paths". There is in ZF and in most set theories. If there is no "all nodes" your claim of "For every node" is impossible. If there is no "all paths" your claim of "For every path" is impossible. You can't have one without the other. > > Actual infinity infinity or set theory, what is the same, claim that > there is a path containing all nodes Only in unary trees.

WRONG!!! Each such path contains only finitely many nodes of 0.000..., but the union of all of them contains more than any finite number of those nodes. > If none of them contains all nodes of 0.000..., then even infinitely > many will not accomplish that goal. If each of infinitely many of them contains a node not contained in any of its predecessors, which is the case, then that union will contain all of them, at least outside of Wolkenmuekenheim > > The union of paths cannot result in more than any contributing path. The set of nodes of the union of even two paths results already in a proper superset of the nodes in any one path, at least outside of Wolkenmuekenheim. > The union can be potentially infinite.

In an infinite binary tree there are no finite paths, and unions of paths do not produce paths at all in any tree, at least outside of Wolkenmuekenheim. |
