Another great read Joren.
Have you ever read about Michel Du Montaigne? Stefan Zweig wrote a biography on the guy — it's an incredible read. Montaigne was one of the first thought leaders with humanism and The Enlightenment. He spent over a decade working on himself in the keep he built at Chateau Du Montaigne that's nestled somewhere in Bordeaux.
Great read and Zweig really gets into the intimate details of his life.
I think after reading this you'd really like that biography!
