Quote from the book "Лонгборн"

If he loved Sarah, then it meant that he was, despite all that he had done, and all that he had failed to do, capable of feeling, and capable of good. Because he wanted nothing from her: this was a generous, expansive feeling, unattached to the possibility of gratification; it was a simple happiness that came from knowing that one particular person was alive in the world. He felt grateful for it; grateful that she had, however unwittingly, enabled him to feel like this.
