FINITE world, or part of a system, or something like that - if my understanding of yours is correct. But my system is to deal with EVERYTHING as a whole. This is philosophy stuff, not a branch of practical science, do I make myself clear to you? Philosophy, like religion, trys to explain the WHOLE, the ONE, the UNIQUE, the BEING... Modeling is certainly not the same kind of stuff. So i really don't get it why you insist that they two should be guided with the same criteria?
