Anything can be an instrument, Chigurh said. Small things. Things you wouldn't even notice. They pass from hand to hand. People don't pay attention. And then one day there's an accounting. And after that nothing is the same. Well, you say. It's just a coin. For instance. Nothing special there. What could that be an instrument of? You see the problem. To separate the act from the thing. As if the parts of some moment in history might be interchangeable with the parts of some other moment. How could that be? Well, it's just a coin. Yes. That's true. Is it?
