Yes, mathematicians. But I don't need to be reminded what a good mathematician or a good professional would do, and, by the way, I am only marginally interested in history, my focus is purely theoretical. That said, the point in question was how could there be a privileged starting point when we are talking about a system whose *essential* nature is the selfreferentiality / the circularity.

There, the point in question was: how could you (or anybody) justify calling that "logic"?

Indeed.

I respect your approach, it's just not mine: I am an ever student, but not any more than anybody else is.
By the way, that link does not work for me, this one does: <https://groups.google.com/forum/#!topic/sci.logic/2HXfcubT468>
