An observer needs a reference point. Although, entertaining multiple reference points while analyzing things around, may seem inviting at times, the trade offs that could lead to weaker analyses as a whole seem imminent. I feel this to be true at this moment due to constraints with processing power that lies in one’s own brain. A lesser fancier way is to say information overload exists.
A reference point could be a set of values with which life can be steered in directions, keeping an acceptable vision of future only to look back with a benefit of hindsight that is deemed to be a comfort. The challenge is to remain tolerant in the face of differences that are present while working and living side by side in diverse communities. This can be analogous to swimming against the tide each day. The necessary condition is a reference point to get some work done.
