The argument culture urges us to approach the world - and the people in it - in an adversarial frame of mind. It rests on the assumption that opposition is the best way to get anything done: The best way to discuss an idea is to set up a debate; the best way to cover news is to find spokespeople who express the most extreme, polarized views and present them as 'both sides'; the best way to settle disputes is litigation that pits one party against the other; the best way to begin an essay is to attack someone; and the best way to show you're really thinking is to criticize.

Each person's life is lived as a series of conversations.

All communication is more or less cross-cultural. We learn to use language as we grow up, and growing up in different parts of the country, having different ethnic, religious, or class backgrounds, even just being male or female - all result in different ways of talking.

In an ongoing relationship, each current criticism packs the punches of all the others that have gone before.

We all know we are unique individuals, but we tend to see others as representatives of groups.

Cooperation isn't the absence of conflict but a means of managing conflict.

The one who decides who goes ahead has the upper hand, regardless of who gets to go. This is why many women do not feel empowered by such privileges as having doors held open for them. The advantage of going first through the door is less salient to them than the disadvantage of being granted the right to walk through a door by someone who is framed, by his magnanimous gesture, as the arbiter of the right-of-way.
