Dear Bruno, thanks for your reply. Please, open up your mind to consider what I was talking about: a *different* mindset, result of a *differrent* evolutionary process - no mathematical (or call it whatever you wish: computational, arithmetic, whatever) LOGIC like we have now, but *something* different. That would not change the word, would, however change our views about it. You asked questions (> How different? <) about this 'different' way *within* the ongoing terminology, how "this 'other' would look if it wouldn't be 'other'." Unfortunately I am also a product of a similar evolutionary process so I cannot muster the 'different' ways, only think about the potential of such. Good enough IMO for just another (unrealistic) thought-experiment.

> What is your god? < I have none, but the term refers to a supernatural being deciding, even organizing and 'creating' the existence (world?). In our "human" terms, of course. By our "human" logic. Within our "human" computational capabilites (or at least fitting such). Just as (my inadequate term) mathematics - as I wrote. (At least in the minds of many learned scientists). Have a happy quantum eternity, just don't get bored after the first 30,000 years of doing what's given in the system. Playing the harp is also a possibility. You may always resort to a quantum suicide.
