It's very sad @stan. Paul was one of the first people to "greet" me here in the world of Steem, and we followed each other's musings quite closely for better than 2 1/2 years, before his "incident." We had some very interesting and enriching philosophical debates along the way!
Seems very much his style to move on, on his own terms, and I salute him for that... but he will be missed.
