We have a responsibility to live well, and the importance of living well accounts for the value of having a critically good life. These are no doubt controversial ethical judgments. I also make controversial ethical judgments in any view I take about which lives are good or well-lived. In my own view, someone who leads a boring, conventional life without close friendships or challenges or achievements, marking time to his grave, has not had a good life, even if he thinks he has and even if he has thoroughly enjoyed the life he has had. If you agree, we cannot explain why he should regret this simply by calling attention to pleasures missed: there may have been no pleasures missed, and in any case there is nothing to miss now. We must suppose that he has failed at something: failed in his responsibilities for living.
