Full Idea
Rather than a sentence being used for prediction because it is a law, it is called a law because it is used for prediction.
Gist of Idea
We don't use laws to make predictions, we call things laws if we make predictions with them

A Reaction
This smacks of dodgy pragmatism, and sounds deeply wrong. The perception of a law has to be prior to making the prediction. Why do we make the prediction, if we haven't spotted a law. Goodman is mesmerised by language instead of reality.
