And not just that... People have failed for thousands of years to define what "good" or "bad" is and everyone sort of works with their own definition. So there is no "moral authority" as such. Or worse, everyone believes they are or belong to "the" moral authority. And the stronger those believes get, the less of a discussion there will be, it will become merely shouting their views.
Socrates said "I know that i know nothing". It is helpful to repeat that to oneself once in a while... and act accordingly: seeking knowledge instead of just trying to spill ones thoughts and want to convince others to accept them no matter what.
The older i get, the more i become a humanist... Funny how things go.
