The Human Stain by corporalevil
"The human stain . . . The stain that is there before its mark . . . The stain that precedes disobedience, that encompasses disobedience and perplexes all explanation and understanding. It's why all the cleansing is a joke. A barbaric joke at that. The fantasy of purity is appalling. It's insane. What is the quest to purify, if not more impurity? . . . The inevitably stained creatures that we are. Reconciled to the horrible, elemental imperfection . . . "
Excerpt from The Human Stain by Philip Roth.
