“Warriors with developed senses of honour and hair-trigger tempers sensitive to the slightest insult make dangerous enemies but they also make uncertain allies. Indeed, Aristotle claims that ‘our anger is more aroused against associates and friends we think have insulted us than against strangers’. This is the dilemma at the heart of heroic values. It is, again, one reason that Homer invites the goddess to sing about anger, one reason that she sings a song in which that anger is first directed against friends and then against enemies.”
