" The line separating good and evil passes not through states, nor between classes, nor between political parties either – but right through every human heart…even within hearts overwhelmed by evil, one small bridgehead of good is retained. And even in the best of all hearts, there remains…an uprooted small corner of evil.

Thanks to ideology the twentieth century was fated to experience evildoing calculated on a scale in the millions.

Alas, all the evil of the twentieth century is possible everywhere on earth. Yet, I have not given up all hope that human beings and nations may be able, in spite of all, to learn from the experience of other people without having to go through it personally. "

― Aleksandr Solzhenitsyn , The Gulag Archipelago 1918–1956 (Abridged)
