When people learn culture, when they burst out of their former unconscious ways and gaze at the new landscape of possibilities, they change in positive ways.

It can wash you away into a sea of anomie. Some lose the certainty of the world that tied them to their original language and never recover. Culture is powerful, and power unrecognized and uncontrolled can destroy rather than create.

Language lies inside the circle. People don't speak the same language. People who speak the same language don't always communicate, and people who learn a second language and stay inside the circle don't either.

Culture is something those people have. It's something that happens to people when they realize that their way of doing things isn't natural law, that other ways are possible. Something they've just heard, something that jolted their sense of who they are, invites them into a different way of seeing.
