Richard Pevear and Laurissa Volokhonsky (New York:  Random House, 2018 [1988]), xxvii.  "their former faith" was in | "what they used to love" was Communism and Stalin and the nobility of The Great Patriotic War, in which they displayed great martial courage.  The "courage of thought" to question all or parts of that was what, I gather (for I haven’t yet read more than this paragraph and the pages preceding it), they were still struggling to muster.
