Full Idea
It is possible that uninstantiated laws can be established in science, and consequently bear explanatory weight, ..if we need reasons for thinking that the closer conditions get to some limit, the more they approximate to some ideal.
Gist of Idea

A Reaction
[The cite Hüttemann 2004] I am dubious about laws, but I take this to be a point in favour of inference to the best explanation, and against accounts of laws as supervenient of how things actually are.
