At the beginning of the previous century, philosophers like Heidegger and Leo Strauss sort of picked up where Hegel left off: I recall Jacob Klein's talk one day on Heidegger. Prior to his encounter with Heidegger, Klein had, by his own account, been "locked up inside of self," unable to "know anything." Then, he went to Heidegger's seminar on Aristotle, perhaps the Physics, I forget which one. Anyhow, for Klein, with this encounter with Aristotle himself, as it were, the door of perception was opened, and Klein was off and running, so to speak, towards truth in philosophy and reason as...LOGOS.Someone needs to write the story of Heidegger in the 1920s: who attended which lectures, shared transcripts, passed notes in class, and so on.
Strauss, too, as I recall, learned from Heidegger that Plato and Aristotle could be read in the light of dia-logos!
I'd be willing to bet that the young Joseph Ratzinger, too, read his philosophy right along with the Church Fathers, Augustine and Bonaventure, etc. The emphasis upon reason as Logos, in Ratzinger's approach to interpretation, is quite pronounced.
