The author's analysis correctly observers the anti-modern sentiment that emerges at various points in the document. I'll be the first to admit, Francis' pointed criticism at the emerging technocratic order and its re-engineering of humanity scored points with me.
Is this a call to arms against modernity, or what modernity has become? Maybe - the jury is out. Will this document have any real effect? The author hits on the document's major weakness: at 200 hundred pages, the audience that will give the document an attentive first read, let alone a detailed reading, is limited.
If Francis manages to reframe the discussion, God bless 'em.
