So I thought I’d dig through the archives over at Voegelin View and I came up with this piece by the beloved and avuncular Dr. Ellis Sandoz:
http://www.voegelinview.com/medieval-rationalism-or-mystic-philosophy-pt-4.html
It’s the fourth part of a series and the other three parts are available on the page.
A search of the site indicates there are quite a few articles/essays and book excerpts related to the relationship between Voegelin and Strauss and on Stauss’s philosophy.
