There is no basic philosophy at the top level from which everything else can be derived. It's like evolution - some things are a bit strange but you can often understand them by looking at how they came to be. There is a tendency however to tag for > What things are? eg highways simply because something can always have side effects that are not related to the primary purpose, or the primary purpose is not immediately obvious. For example, a motorway is not only a transport feature, it is also an insurmountable barrier for pedestrians or cyclists. Tagging is very often based on what you see, not what you know. If you see a body of water (and you might be doing that from aerial imagery, sitting 1000s of miles away), you tag it as a body of water even if you don't know whether this is an artificial reservoir that supplies drinking water or a crater lake or anything else. Tagging > What things are used for? eg amenity might require more knowledge than the mapper has, especially in the case of mapping from aerial imagery.
