The Gulag Archipelago (1958–1986), by Aleksandr Solzhenitsyn

Aside from being a powerful accusation of Marxism as a social system, the value of this book is in that it is addressing the hidden psychological aspects of Marxism that permeate the mentality of all without exception post-communist people who, even many generations later, still operate using the Marxist methods of thinking, for example, the Marxist / Leninist technique of "hacking from the shoulder". This is rooted in Marxist / proletarian psychopathic disregard of a human being. Another important note is that the intelligent human being must at all cost defend his / her dignity and his human right, even wen facing fear of society. There was very little personal and no group resistance to NKVD, and things would have turned out differently if people resisted. Resist. Stand up for your rights. It's your spiritual duty.

Also: lack of preparedness. Lack of preparedness equals fear. One must be prepared for an attack, and prepared at any point to counterattack.

Having found yourself in a paranoid social situation or at the mercy of a paranoid personality, do not consider yourself exception from the common condition, and do not demonize others.

I also want to add that it's the ideal book, in my opinion, because it shows the kind of motivation a writer must have in order to write. Writing must be rooted in one's destiny, and the force of the writer's spiritual duty must force him to write. Most of other books seem accidental by comparison with The Gulag Archipelago.
