Balance is a key principle in many things. Often we find ourselves between two options, and the instinct is to try and discern one as good and the other as bad, simple black and white thinking. But often what ends up being best to find a balance somewhere in the middle.
This does not necessarily mean we ignore the situations where one side is right or the spectrum is discrete (between two choices)
It also does not mean that we should always seek the middle or centrism just for its own sake. Placement and balance on any spectrum is decided using the same principles of evolution and nature that it all stems from.
