How about developing representative democracy based on personal sovereignty, (exactly)?
That man (Singer) is being intellectually dishonest, trying desperately to find reasons for this wonderful modernity other than the influence of those simpleton “JudeoChristian” values we hear so much about. It was the move away from superstition and paganism (brought on by the great monotheistic religions of Judaism and Christianity) that allowed the Western world to move forward and those that didn’t follow to stay the same. And I believe there is every chance we most certainly will slip backwards into the same idiotic abyss when we quit drafting off, yes, Christianity. So there.
