Neutrality

One interpretation of the Masonic checkerboard floor is that neutrality is the "true" point of view. The sides of light and dark or any two political sides of a human conflict are severely flawed and limited in perspective. The neutral party has the only "true" view.

With some discipline, a person can abandon the urge to belong to a side. There are a lot of representations of this type of character in fiction, movies, and TV shows. The Maesters on the Game of Thrones are one example.

They are meant to be advisors to the party that happens to be in charge of a political unit. The seer on Vikings is another such character. Lex Luthor on Smallville represents this sort of character until he goes totally dark side. Varys on the Game of Thrones is another such character.

The neutral position, unfortunately, ends up being hard to distinguish from the "moral imbecile" or psychopath. Sherlock's brother is a good example of this type. Rather than obtaining an elevated position via their detachment, or obtaining a position of higher consciousness the neutral can end up as a mere calculator and schemer, so the only element of their humanity they retain is a desire to dominate and win. For this type there's no philosophy, only sophistry. There's no truth telling, only rhetoric.
