Is that the Copenhagen Interpretation of mathematics or something ? Are you implying that if there were no such thing as thought, that there would be no such thing as logic ? So there must be life in order for there for there to be any logic, because without life there can be no thought.

But logic _isn't_ thinking. It maybe that when people do logic they need to think, but machines can "do" (at least some) logic also. -- I can't go on, I'll go on.

Exactly as that: if there's no thought then we cannot asset anything about anything, and this was perhaps what Monsieur Descartes was trying to convey. Tonio

And with no logic, why then would physics make any sense ? Why does the universe continue if there is no logic ? Are you saying that when all life has died, the we can have time travel, FTL communications, cold fusion and antigravity motorcycles ? If there were no life here to observe things....then 2 + 2 would equal 7 ???

You can't contradict me, so my claim is safe. **wink!** Tonio |
