Here you are appealing to the same thing as I was: It's hard! Life is a journey. You don't get the answers all at once. But the joy is in the discovering. More below on my statement about comp being a lot of work. > Also, with comp, machines HAVE TO be "theological > machine". That is, comp does not prevent some "mystical" (true but > unprovable) beliefs: on the contrary, comp makes them obligatory (at > least for the ideally correct machines). > > With comp we can argue that consciousness is already such a mystical > state.

It is actually anti-God to proclaim (as religious fundamentalists do) that we (as a very small subset of reality) have all knowledge. If such a claim were true, then such a "knower" would be in a static state, rather UNlike consciousness. > The closer thing to consciousness for the lobian machine is the "state > of being consistent".

The theists will have been there through faith, not the anti-evidential "faith" of the fundamentalists, but the faith that is believing what is not seen, being able to "see" the whole without having to put it together from parts like the Tower of Babel. > Note that I am not equating consciousness and consistency.

But the weakness of simple consistency is the unanswered question, "What is truth?"

I would not put up a dichotomy between this attitude and a belief in God. But perhaps your use of the word "scientific" is based on your conviction to use the word as you think it "should" (assuming comp? ;) be used, rather like your use of the word "theology". Actually I'm starting to think that you really aren't that far off in your use of the word "theology" for the search for truth.
