I think Chapman is acutely aware that postmodernism poisoned the well of the humanities and largely killed them. Now, the stem nerds have to repeat history, by reinventing and reimporting hermeneutics into their intellectual canon. It is happening largely outside academia, and somehow the inevitable next step after Bayesianist epistemology infused rationalism has reaped the low-hanging fruits and lost most of its steam. Postrationalism marks the return of the narrative in nerd intellectualism. Those few folks that are still alive and sufficiently versed in the scholastic canon of the prepostmodern humanities may scoff at it, but I think Chapman is serious, has high intellectual integrity and may gain serious cultural impact. Thanks to Kegan and Caplan, he also found a bunch of sufficiently original starting points to make it worth wile following his explorations.
