 This may not seem like much of a puzzle. That everyone here is seated is spatially restricted in that it is about a specific place; the principle of relativity is not similarly restricted. So, it is easy to think that, unlike laws, accidentally true generalizations are about specific places. But that is not what makes the difference. There are true nonlaws that are not spatially restricted. Consider the unrestricted generalization that all gold spheres are less than one mile in diameter. There are no gold spheres that size and in all likelihood there never will be, but this is still not a law. There also appear to be generalizations that could express laws that are restricted. Galileo’s law of free fall is the generalization that, on Earth, free-falling bodies accelerate at a rate of 9.8 meters per second squared. The perplexing nature of the puzzle is clearly revealed when the gold-sphere generalization is paired with a remarkably similar generalization about uranium spheres:
