Conventional wisdom is not arbitrary. Traditional values and principles did not become traditional randomly. The entirety of human history has been a trial and error experiment, with the things proven true and useful becoming the universally accepted core values of society. And it is not as though these values were never challenged, were never defied, were never rejected; it’s just that those experiments in renunciation ultimately did not produce better results for the preponderance of people.
There will always be an immaturity in defiant and rebellious ideas and reinterpretations, not because they are original (they most certainly are NOT original), but because they have never lasted long enough to mature. I would argue that most progressive innovations in our values have not required rejection, but expansion in the application of core traditional values. Where innovations contradict traditional values, they will be doomed. Where they identify ways in which core values need to be more comprehensively implemented, they can succeed.
