Dr. John Reist once drew me a map to his house when I was a student in one of his classes at Hillsdale College. It started with a circle, which he said was God and he said "There is a God and she's black." "Hey whoa," he said. About 10 minutes of map drawing and jokes later, I realized it was actually a straight line from the college to his house. No turns or anything. But still that map, like all the lessons Reist taught, turned out, kinda mysteriously, to be profoundly useful.
Rest in peace, Dr. Reist. Quack to you too, and rest in peace.
