Much later that night, after I'd met with a group in Lewisburg and had climbed into bed near midnight, the question of why I'd stopped for that light came back to me. I think I stopped because it's part of a contract we all have with each other. It's not only the law, but it's an agreement we have, and we trust each other to honor it: we don't go through red lights. Like most of us, I'm more apt to be restrained from doing something bad by the social convention that disapproves of it than by any law against it.

It's amazing that we ever trust each other to do the right thing, isn't it? And we do, too. Trust is our first inclination. We have to make a deliberate decision to mistrust someone or to be suspicious or skeptical. Those attitudes don't come naturally to us.

It's a damn good thing too, because the whole structure of our society depends on mutual trust, not distrust. This whole thing we have going for us would fall apart if we didn't trust each other most of the time. In Italy, they have an awful time getting any money for the government, because many people just simply don't pay their income tax. Here the Internal Revenue Service makes some gestures toward enforcing the law, but mostly they just have to trust that we'll pay what we owe. There has often been talk of a tax revolt in this country, most recently among unemployed auto workers in Michigan, and our government pretty much admits if there was a widespread tax revolt here, they wouldn't be able to do anything about it.
