Only finished the first one so far, but it goes into a bunch of "isms" from the Catholic view that have been "crises", and I recall this set of lectures being referenced by other "traditionalists".

One thing that popped out at me that I'd think this community would discuss was the author attacked nationalism as being divisive and related to heresy. Yet, I'm guessing what people here call "nationalism" the author might think of as "patriotism". Still, there are various heresies that arise from nationalism (and I haven't seen that topic discussed openly as much), and various "nationalistic" (patriotic) impulses that to me seem fine with respect to Catholicism.
