Solzhenitsyn as an Augustinian

Although Orthodox Christians are generally ambivalent about St. Augustine and are not certain they approve of his "western" theology, one such Christian, Aleksandr Solzhenitsyn, appears to have read him. Augustine's influence is evident in the following passage taken from The Gulag Archipelago:

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. Even within hearts overwhelmed by evil, one small bridgehead of good is retained; and even in the best of all hearts, there remains a small corner of evil.

It would be difficult to articulate a more profound insight into human nature than this one, with its obvious debt to the one whom the Orthodox call the Blessed Augustine.
