What ultimate knowledge is hidden and how do we get it to the people so they can be "good" instead of "evil".

"Good" and "Evil" are controversial concepts. For example, for some, drinking wine is "evil", but for others it is "good", perhaps in moderation, because it is enjoyable and a personal choice. It might be objectively considered "evil" if it impacts the lives and rights of others ... e.g., an alcoholic parent whose habits adversely affect family members and/or the community.

Who is to be the judge of good and evil? What degree and extent of knowledge puts one in the place to judge? What signifies the attainment of such position?

I loved Plato's 'Republic', but some of it smacks a bit of "elitism" and "holier than thou" narcissism. It focuses too much on the "leader qua leader", and not enough on the "followers". We've seen some pretty bad "leaders". "If gold rust, what shall poor iron do?"

For some judgmental types, being "white" is bad, but what are white people supposed to do? Really?
