This "Welcome, Visitors!" topic has turned into a really heavy discussion of logic.
I was thinking of forcing it to go to a new topic, by closing this one.
Instead, I have renamed the topic, from the ambiguous "Question...." to what I hope is the better "Question.... (Processes of Logic)".
The moral of the story is, it's best for a good topic string to have a good title. Or something like that.
