I have never read one of Solzhenitsyn's novels. I intend to do so before long, perhaps starting with August, 1914. But I have read many of his essays, interviews and speeches, including the Harvard speech of 1978. His passing this week generated considerable commentary about this great and courageous man, and his place in the momentous events of the 20th century. In my view, some of the best are as follows:
Andrew Cusack, here.
George Friedman, here.
Fr. Stephen Freeman, here, here and here.
Daniel Larison, here.
Terry Mattingly, here.
