Mass is Inertia......In physics, mass means the tendency of an object to resist changes in course or speed. It is what physicists call inertia. Inertia is a kind of I don't like to be pushed feeling....

The fact is, either approach is correct and one does not preclude the other. Yes, the Principle of Relativity is elegant and the top-down approach is easier to use; physicists love it for that reason....
