Some philosophy consists of the exploration of formal systems, and some of it consists of expressing opinions in a weird parody of the above. (Go read Socrates's arguments* and find all the logical flaws and fallacies that his conversants conveniently ignore. We may like some of his opinions, but to believe they're derived with rigor is laughable.) The problem with physicists getting into philosophy is that they're generally only doing the second, less useful thing. * Of course it's just Plato relating what he says are Socrates's arguments, so there's that too.
