On the fourfold division of society, and who is to be regarded as highest.

 It's possible to divide society into:

1) kings, who maneuver.

2) nobles, who apply (they are small-medium business owners or executives at large businesses)

3) brahmins, who strive (they determine the favored narrative)

4) country-folk, who work

We can say that these are the four classes of society.

The important part:

It is the nobles, not the kings or the brahmins or the country-folk who are to be regarded as the highest in this class classification.

When the kings is regarded as the highest, conceit will corrupt & destroy the kings. The same logic applies to the brahmins or the country-folk.

This is NOT true for the nobles! When nobles are regarded as the highest, conceit will NOT corrupt & destroy the nobles. Hence, this is an important viewpoint update to make.
