Cumulative Record: Definitive Edition (1999). Chapter 3:Some Issues Concerning the Control of Human Behavior. Quote 5

The individual is especially likely to be praised, admired, or loved when he acts for the group in the face of great danger, for example, or sacrifices himself or his possessions, or submits to prolonged hardship, or suffers martyrdom. These actions are not admirable in any absolute sense, but they require admiration if they are to be strong. (p. 27)
