Reading Wickham’s The Inheritance of Rome: Illuminating the Dark Ages 400-1000 has made me aware of something outside his storyline: the normal, routine, and unremarked willingness of medieval peasant-soldiers, leaders, bands, and armies to slaughter one another, to kill the disarmed, to enslave prisoners, and to do all these things with apparently no compunction. Vikings, Franks, Bulgars, Huns, and Romans massacred and burned. Here is just one example, from the wars of Charlemagne:
What are we to make of this fairly simple historical fact about the behavior of our human ancestors a mere 1500 years ago?
Does it imply that “human nature” is inherently cruel and indifferent to the suffering of other human beings, and that compassion is a cultural discovery or innovation?
Does it imply that restraints on violence depend upon social structures and cultural creations — laws, norms, and institutions setting boundaries on violence?
Is there such a thing as a “civilizational” turning away from violence against the innocent? Did human institutions (military law, international conventions, religion) and invented and disseminated moral values (“it is horrible and shameful to harm or kill the innocent”) change the occurrence of atrocity? (John Keegan quotes views to this effect to explain the fact that studies indicated that only 25% of battlefield soldiers fire their weapons in World War II.)
The Ten Commandments have been the foundation of monotheistic religious ethics for more than three thousand years -- including the prohibition against murder. Did monotheistic religions change the behavior of individuals, bands, armies, and states? Were Christian Visigoths or Vandals less cruel in war? Did the armies of Islam commit these same kinds of atrocities, or did the kindness preached by the Prophet prevail? What about ancient Judaism and Jewish communities? For that matter, what about the converts to Judaism in the Khazars — did they massacre their enemies just as wantonly?
Most importantly, does this changing history of cruelty on a mass scale suggest that our human sensibilities themselves have changed in a millennium and a half, so human beings in typical social circumstances are no longer so ready to kill and maim their fellow human beings? Does a religion, a personal value scheme sincerely embraced, or adherence to an ideal of how one should value the human experience and life of anonymous others effectively change a person's social psychology? Can compassion and pity be learned or culturally reproduced?
But if so, what about My Lai, Lt. Calley, and Abu Ghraib Prison? What about Isis beheadings, burnings, and rapes? What about the vicious brutality of Trump rioters against police on January 6?
Here is a fairly concrete question: what did ancient writers and philosophers have to say about the killing of the innocent? Did Seneca or Lucretius make any pronouncements on the behavior of armies, massacre, or killing of the innocent? Here is Seneca, writing in roughly 50 CE, about the morally corrosive effects of the crowd at the "games" (Letters from a Stoic):
2. To consort with the crowd is harmful; there is no person who does not make some vice attractive to us, or stamp it upon us, or taint us unconsciously therewith. Certainly, the greater the mob with which we mingle, the greater the danger.
But nothing is so damaging to good character as the habit of lounging at the games; for then it is that vice steals subtly upon one through the avenue of pleasure. 3. What do you think I mean? I mean that I come home more greedy, more ambitious, more voluptuous, and even more cruel and inhuman, because I have been among human beings. By chance I attended a mid-day exhibition, expecting some fun, wit, and relaxation,—an exhibition at which men’s eyes have respite from the slaughter of their fellow-men. But it was quite the reverse. The previous combats were the essence of compassion; but now all the trifling is put aside and it is pure murder. The men have no defensive armour. They are exposed to blows at all points, and no one ever strikes in vain. 4. Many persons prefer this programme to the usual pairs and to the bouts “by request.” Of course they do; there is no helmet or shield to deflect the weapon. What is the need of defensive armour, or of skill? All these mean delaying death. In the morning they throw men to the lions and the bears; at noon, they throw them to the spectators. The spectators demand that the slayer shall face the man who is to slay him in his turn; and they always reserve the latest conqueror for another butchering. The outcome of every fight is death, and the means are fire and sword. This sort of thing goes on while the arena is empty. 5. You may retort: “But he was a highway robber; he killed a man!” And what of it? Granted that, as a murderer, he deserved this punishment, what crime have you committed, poor fellow, that you should deserve to sit and see this show? In the morning they cried “Kill him! Lash him! Burn him! Why does he meet the sword in so cowardly a way? Why does he strike so feebly? Why doesn’t he die game? Whip him to meet his wounds! Let them receive blow for blow, with chests bare and exposed to the stroke!” And when the games stop for the intermission, they announce: “A little throat-cutting in the meantime, so that there may still be something going on!”
Come now; do you not understand even this truth, that a bad example reacts on the agent? Thank the immortal gods that you are teaching cruelty to a person who cannot learn to be cruel. 6. The young character, which cannot hold fast to righteousness, must be rescued from the mob; it is too easy to side with the majority. Even Socrates, Cato, and Laelius might have been shaken in their moral strength by a crowd that was unlike them; so true it is that none of us, no matter how much he cultivates his abilities, can withstand the shock of faults that approach, as it were, with so great a retinue. 7. Much harm is done by a single case of indulgence or greed; the familiar friend, if he be luxurious, weakens and softens us imperceptibly; the neighbour, if he be rich, rouses our covetousness; the companion, if he be slanderous, rubs off some of his rust upon us, even though we be spotless and sincere. What then do you think the effect will be on character, when the world at large assaults it! You must either imitate or loathe the world. (Seneca, letter VII)
The text treats cruelty obliquely. This is not his primary target; rather, Seneca uses the scene of the "exhibition" as an occasion for making a different point -- the harmfulness of associating with "the crowd". But in his framing of the example, he makes it clear that he sees the behavior of the crowd as detestable and awful in its bloodthirstiness and cruelty. And he sees the behavior as contagious: when a virtuous person -- even a Socrates or Cato -- is exposed to this sight, he will be harmed in his virtue. And why is this cruelty awful? Because, it would seem, it involves the horrible imposition of pain, mutilation, and death on the weak, for the entertainment of the many. It is recognition of the human reality of the pain and desperation of the victims that motivates Seneca, it seems; he is empathetic with these other unfortunate human beings.
The historical evolution of massacre and cruelty raises huge and important questions. The topic converges with an earlier discussion of the Athenian massacre of the Melians, described in Thucydides (link). And the questions are genuinely difficult to answer. Human nature? Moral progress? The favorable role of religion? Institutions designed to limit violence? Perhaps some will even consider the intuition embraced by Dr. King in 1967 -- "The moral arc of the universe is long, but it bends towards justice." But if we want to understand the particular evils of the twentieth century -- Holocaust, Holodomor, and Gulag, to name just the most awful -- we need to consider the nature and situations of the human beings -- versions of ourselves -- who have committed acts like these at other times in history.
