Solzhenitsyn

An insight that came to Solzhenitsyn in the gulag during the first stages of his conversion from Marxism while he lay "on rotting prison straw" -

"Gradually it was disclosed to me that the line separating good and evil passes not through states, not 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 remains.  And even in the best of hearts, there remains....an unuprooted small corner of evil."
