I'm still working through The Gulag Archepelago by Aleksandr I. Solzhenitsyn. Actually, I'm only at page 150. I think there are ~900 pages total?
It is, at the same time, both compelling and repellant.
It's compelling to read what the Soviets did, how people did/didn't respond and what they did to survive.
But it's also extremely stomach-churning to read. And I put it aside for long periods of time but am not able to keep away from it.
A couple of (kind of trivial, in light of the subject matter) thoughts about it so far:
-- the whole Guantanimo is Gulag thing is absolutely dumb and incorrect. I suspected as much, but wasn't sure, having never read any thing in it.
-- The most oft quoted Solzhenitsyn line about, "The line between good and evil runs through the heart of every human being," is most oft misquoted. Almost every time I read it the user is trying to justify moral equivalence, Solzhenitsyn writes it to say that there is absolutely good and evil, and the struggle is to choose good.
-- Everyone should read it, especially critics of Classical Liberal Democracy & the Free Market System.
But I'm only 1/6th of the way through it. I might change my mind three or four times between now and then.
