"The long-running debate about whether humans are capable of genuine altruism is, in practical terms, less significant than the question of how we understand our own interests. Will we understand them narrowly, concentrating on acquiring wealth and power for ourselves? Do we think that our interests are best fulfilled by a lifestyle that displays our economic success by our ostentatious consumption of as many expensive items as possible? Or do we include among our interests the satisfactions that come from helping others?"
