Indeed, much Continental philosophy in general is phony and pretentious when read as pseudoscience. That kind of philosophy is more like bad prose poetry than like empirical modeling of objective facts. And that book did indeed expose the low standards in that field.

But remember that the social sciences themselves have a replication problem, so their standards, too, have been corrupted by capitalism. Even in theoretical physics, there's a growing sense that the science has been led astray by the exotic math, that the standard model may have to be reconstructed.
