I suppose what I need to know is how the existence (in any sense) of the integers and elementary arithmetic operations creates computations. In fact every possible computation. I believe it's done indexically, whatever that means ... but I think this is about where I start to feel I shouldn't bother my pretty little head. If the sheer existence of numbers, + and x implies that all possible computations "exist "(in an abstract sense) then it all follows - in an abstract sense. This brings me back to your comment about equivalence (or not). The thing is, I'd like to know what I'm buying or not buying before I decide whether to buy it! -- You received this message because you are subscribed to the Google Groups "Everything List" group.
