Dreher instead provides us with a thoughtful explanation of Tolkien's complex morality, including his admonitions about the blurred line between good and evil that runs through each human heart.

Of course the "line" quote is Solzhenitsyn. and he did not call it "blurred."

[don-o]

"The line separating good and evil passes not through states, nor between political parties either - but right through every human heart."

I believe the rest of the quote is"...and who is willing to cut out a piece of his own heart?

More Solzhenitsyn quotes

The metaphor of a line through each human heart is biblical in origin and has been used so often by so many authors over the centuries that no single writer can claim credit for it.

I'M calling it blurred. I believe Tolkien would agree.
