Most of us have but one nationality, one ethnicity, one profession, one taste in music, one generation, one social status, one system of ethics and one among a several combination of factors that constitute the human experience.
We expand this tiny slice of human experience to construct our entire view of the world, like a thumbnail photo being stretched out to cover a large screen TV.
Is there any wonder, that most of what we see is hazy and pixelated? Why do we expect otherwise?
