A ‘true analyst’ is one who profits from his choices, and this is ethical?

The Parallax View (MIT Press, 2006), p. 98:

Recall Henry James’s “The Lesson of the Master,” in which Paul Overt, a young novelist, meets Henry St. George, his great literary master, who advises him to stay single, since a wife is not an inspiration but a hindrance. When Paul asks St. George if there are no women who would “really understand – who can take part in a sacrifice,” the answer he gets is: “How can they take part? They themselves are the sacrifice. They’re the idol and the altar and the flame.” Paul follows St. George’s advice and renounces the young Marian whom he passionately loves. However, after returning to London from a trip to Europe, Paul learns that, after the sudden death of his wife, St. George himself is about to marry Marian. After Paul accuses St. George of shameful conduct, the older man says that his advice was right: he will not write again, but Paul will achieve greatness… Far from displaying cynical wisdom, St. George acts as a true analyst: as the one who is not afraid to profit from his ethical choices, i.e., as the one who is able to break the vicious cycle of ethics and sacrifice.
