"Perhaps now you can see why I stress the importance of viewing obligations as a relationship between people, not between one person and some impersonal idea or principle. An idea, when violated, cannot make reprisals. A principle cannot refuse to shake my hand. Only people can do that. And it is this social power, the threat of social consequences, that stops me from making a full and complete break. Peace of mind is not a simple matter of pursuing one's own pleasure; rather, it is inextricably linked to the attitudes of other human beings, to what they want, to what they expect. The real issue is how to find felicity within limits. Within the context of our obligations to other people. We all want peace. We all want dignity and domestic tranquility. But we want these to be honorable and lasting. We want a peace that endures. We want a peace we can be proud of. Even in imagination we must obey the logic of what we started. Even in imagination we must be true to our obligations, for, even in imagination, obligation cannot be outrun. Imagination, like reality, has its limits."
