It was granted me to carry away from my prison years on my bent back, which nearly broke beneath its load, this essential experience: how a human being becomes evil and how good. In the intoxication of youthful successes I had felt myself to be infallible, and I was therefore cruel. In the surfeit of power I was a murderer, and an oppressor. In my most evil moments I was convinced that I was doing good, and I was well supplied with systematic arguments. And it was only when I lay there on rotting prison straw that I sensed within myself the first stirrings of good. Gradually it was disclosed to me that 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. And even within hearts overwhelmed by evil, one small bridgehead of good is retained. And even in the best of all hearts, there remains … an un-uprooted small corner of evil.

Since then I have come to understand the truth of all the religions of 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 in 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 then take to themselves as their heritage the actual evil itself, magnified still more.
