This is a brilliant essay, on a topic I write about as well. What strikes me is that as babies, we are immersed in a culture that cannot help but shape us. "Culture is the person we are together" beginning with family.

It is hard to get perspective on another culture because it involves translation of one weltanschauung for another. It isn't that ideas don't translate so much as the emotional load of the idea that our birth culture instilled in us. You can do it: indeed, in our time you must learn to live with people of different cultures.

Where it ends up being neuralgic is determining what is moral. "We live in an age where everything is permitted and nothing is forgiven." (Alan Jones)
