Walking around Berkeley, California, nothing is more clear than the diversity of dress.
But ironically, the Martian anthropologist notes to himself, diversity of dress tends to point to enclaves who won't speak to each other.
The very people clamoring for diversity of -culture- speak several languages, but their single culture of dress represents one visual language which others will never speak to.
I walk down the tree-lined avenues, and a thousand visual languages are clamoring about their view of the human soul, and each meets speakers of other languages with scorn.
