Does it explain anything?
Personally I feel quite comfortable with the best systems approach to the laws of nature. It doesn't seem to involve "spooky metaphysics", as Loewer calls it. But it also makes me a little sad. It seems to suggest that we can only ever describe the world, by spotting the patterns within it, but never really understand it. Loewer points out, however, that some understanding resides in the unification of laws. Newton's great insight was that the same set of equations describes the behaviour of all objects, be they pendulums or footballs here on Earth, or planets and comets up in space. Having such a unifying description does feel like we have understood something significant about how the world works.
But it's a subtle business. If we really want to explain the phenomena we see around us, we need to spot chains of cause and effect and that's a famously tricky problem. We suspect that one thing causes another when both things tend to appear together. But correlation isn't causation: it may be purely coincidental, or down to hidden factors we haven't yet spotted. Just how one can discern whether a correlation is a causation, if there even is such a thing as causation in the vast Humean mosaic, is another question philosophers vigorously debate. We'll leave that for another time.
