Inasmuch as I cannot point to ANY government at all, which has endured and functioned well... I guess I'd have to say no.
Are you suggesting that the lack of a predicate is sufficient reason to dismiss a governmental form?
It does make its undertaking more a matter of trepidation, doesn't it? However, many enduring and well thought of governments have been created and existed without a single underlying foundational principle and to ask the one question as central would imply the other would be as well. In truth, the worth of a man, or a government, is not as simple as either question would imply.
We are seriously off the original topic of the thread, and the topic we are exchanging comments over, we have done to death countless times with few converts on either side.
When the Republic was threatened by the Clinton presidency, we were both here and I will settle for that.
