Gödelian arguments are inescapable; you can always isolate the framework-of-trusted-arguments if a mathematical system makes sense at all. Maybe the adding-up-to-normality-ness of my system will become clearer, after it becomes clear that you can always isolate the framework-of-trusted-arguments of a human having a moral argument.

If you hadn't qualified the two statements beginning with, "you can always isolate the framework..." then it seems they would not escape Gödelian arguments. In other words, there is no reason to believe that there isn't a non-isolate-able, general moral Framework, but I suspect that you are right that it would have to be neither mathematical (small 'm') nor of-a-human. ^^

Do I represent well the principles discussed when I say this? ;)
