Compare that to TO-illogic. Virgilogic conforms in all respects to standard logic and standard mathematics and TO-illogic conflicts with both.

As virtually each of TO's claims contains sufficient internal evidence to demonstrate its errors, long memory is not required.

You artificially create this "after" using the Zeno > paradox machine, but that is a ruse. Actually, it is the problem itself which creates the "after", as it specifically asks about the situation at a time after all the insertions and removals have been completed. So TO is dreaming again about a problem that does not exist except in his imagination. > You are claiming the unending set > ends, while you accuse me of not understanding that unending sets don't > end.

The set of numbers on balls nserted before noon is N The set of numbers on balls removed after insertion but before noon is also N.

I see nothing in the original problem that would stop time.

One can claim that the vase problem cannot occur in any physical sense, but if one accepts the statement of the problem, the only conclusion which does not require assumptions not inherent in the problem itself is that at noon the vase is empty. > > One certainly starts with more balls.

When one starts with all infinitely many balls in the vase and then balls are removed on the original schedule, there will be infinitely many in the vase at all times from that group insertion up to but not including noon. > > > > >> You really > >> don't understand the implications of the Zeno machine, do you?
