Abstract

Certainly I am in no way opposed to philosophy, or metaphysics in the sense that Wm. James defined it as a particularly intense effort to think clearly. Indeed, Klein would like to say that what I am talking about is nothing but metaphysics. But the kind of philosophy/metaphysics that is needed here is of a particular kind: a kind that does not separate philosophy/metaphysics and physics into two disjoint realms. It is of the kind that seeks to construct useful testable physical theories that are adequately connected to what we can know
