Physics, Metaphysics, and the Problem of Progress

Metaphysics is often held to be continuous with science. And in many respects it is: it has similar aims and (many think) it may even employ a similar methodology.  However, it is arguably very different in one crucial respect: while science clearly makes progress, it is very much less clear that metaphysics does. This gravely impacts the value of engaging in metaphysics of physics prior to a final theory.  Or so I think: in this talk I will explain why I believe this, and respond to some objections that have been made to my argument.
