There are infinite sequences that do not converge. And 1 + 2 + 3 + ... is one of them.

It is sufficient that for each term in a sequence there be more than one option in order for the set of all such sequences to be uncountable. > But that is > not the case in the binary tree.

But you claim them uncountable. The set of all paths through any particular edge is separated from the set of all paths not through that edge, and each edge produces two uncountable sets in this way. In a similar fashion, each node exxcept the root ode does likewise. > > The union of a family of sets need not be a subset of any > > of them. > > Not in general, but if the elements are linear ordered sets. > > > > But unless we assume that there can only be finitely many we cannot > > conclude that there is a last or largest conctaining all the others. > > It is enough to know that each one is finite. That does not assure that the union of infinitely many such finite sets is finite. And, in fact, a union of infinitely many distinct finite sets cannot be finite.

In other words, Jonathan, Aristotelian syllogistic inference only yields truisms not truth. It can't tell us what the truth of anything actually is only whether or not it's true in relation to constituent premises of equally problematic truth. The truth of conclusions is not inherited from the truth of constituent premises as syllogistic inference implies and Aristotle thought. The truth of any conclusion must be demonstrated in its own right by demonstrating the falsity of alternatives by finite tautological regression to self contradictory alternatives. ~v~~
