These days, as I reflect on the explosive aftereffects of the incineration of copies of the Quran in a US military base in Afghanistan, I find myself re-reading chapters 1-11 of Book Two of Aristotle’s Rhetoric, where he offers his treatment of the passions (the Greek is pathē, from which we get all those “path” terms, like sympathy, empathy, apathy, pathetic, and so on). This “theory of moral sentiments” comes in the context of “a theory of rhetoric”: a reasoned discourse offering analysis and advice concerning the political use of composed speech in situations where persuasion is based on something other than “purely” rational conviction. Central to what Aristotle has to say is that human beings experience anger on those occasions when they: (1) believe that they themselves or something that they hold dear (or, especially, most dear) has been belittled and (2) cherish a wish for revenge. The paradigmatic example is Achilles, who believing himself to have been robbed of his honor (which is what was most dear to him at that time) by Agamemnon, displays his anger precisely by predicting and praying for (and then enlisting the gods’ support for his predictive prayer) the devastation of the Greek army as a punishment to Agamemnon. This is especially exemplary in that, among other things, it shows why what we euphemistically call “collateral damage” is so endemic to “the work of anger.”

The terrible events that have followed the burning of the Qurans by insufficiently sensitive and ill trained personnel, sadly, were entirely predictable in terms of Aristotle’s account. The anger, with its destructive thirst for revenge, that a believer feels in seeing the testament burned unceremoniously as refuse is immediately understandable for someone who has taken the slightest moment to conceive of how a Muslim relates to the sacred word, and how it differs from the way in which a Christian relates to the sacred word. With just the smallest degree of education—precisely the kind of education Aristotle is trying to provide in his Rhetoric—one could see at an instant . . .
