Rorty of course makes a similar argument. When we were covering Marx last semester, I had my students read a small portion of one of Rorty's essays on whether and how we should read Marx, and he essentially gave the Jamesian argument on religion and specifically tied the New Testament to Capital. Do read Marx, Rorty said. Read and internalize what it behooves you to and no more. This was argued in contrast to some statements from Derrida on the modern relevance of Marx.
