No need to hurry. Tarski has his merits. He is a great mathematician. No
doubt about it. But the so called foundation of logic in set theory has
failed, good old Cantor has failed trying to codify it, and wether this
remains apropos today is disputable. From my own experience I can tell, for
software development and things around that, I don't need a Tarski-view of
the world.

I hope this isn't too much off topic from this 95-percent-lurker. I
apologize, if someone thinks so.
