Aleksandr Solzhenitsyn

The line separating good and evil passes not through states, nor between classes, nor between political parties either - but right through every human heart - and through all human hearts. This line shifts. Inside us it oscillates with the years ... I have come to understand the truth of all the religions on the world. They struggle with the evil inside a human being (inside every human being). It is impossible to expel evil from the world in its entirety, but it is possible to constrict it within each person. And since that time I have come to understand the falsehood of all the revolutions of history: they destroy only those carriers of evil contemporary with them (and also fail, out of haste, to discriminate the carriers of good as well). And they take to themselves as their heritage the actual evil itself, magnified still more.
