"A dirty river of evil is poisoning the geography of human history," fruit of "the contradiction within the human being."

Each person is called to do the good, and intimately wants to do it, but at the same time is driven by the impulse to do the opposite, to follow the path of egoism and violence, of doing what he or she wants knowing that he or she is acting against God and his/her neighbour."
