When I see developmental hierarchies such as those from from Lawrence Kohlberg and Ken Wilber, I see liberalism arising out of conservatism. For that reason, I’m surprised liberals can’t relate better to conservatives. Liberals have been there. Maybe no patience for something they’ve left behind?
Yes in essence. Each new wave feels more correct than the one it displaces. The overarching context is that only one perspective is 'correct'. Wilber describes 2nd tier as the wave where the thinker sees 'correctness' as contextual so can relate to all previous levels and act from them by choice.
