the harm is ultimately explicable. The viewpoint of the moralist, in contrast, is the viewpoint of the victim. The harm is treated with reverence and awe. It continues to evoke sadness and anger long after it was perpetrated. And for all the feeble ratiocination we mortals throw at it, it remains a cosmic mystery, a manifestation of the irreducible and inexplicable existence of evil in the universe. Many chroniclers of the Holocaust consider it immoral even to try to explain it.41
Baumeister, with psychological spectacles still affixed, calls this the myth of pure evil. The mindset that we adopt when we don moral spectacles is the mindset of the victim. Evil is the intentional and gratuitous infliction of harm for its own sake, perpetrated by a villain who is malevolent to the bone, inflicted on a victim who is innocent and good. The reason that this is a myth (when seen through psychological spectacles) is that evil in fact is perpetrated by people who are mostly ordinary, and who respond to their circumstances, including provocations by the victim, in ways they feel are reasonable and just.
The myth of pure evil gives rise to an archetype that is common in religions, horror movies, children’s literature, nationalist mythologies, and sensationalist news coverage. In many religions evil is personified as the Devil—Hades, Satan, Beelzebub, Lucifer, Mephistopheles—or as the antithesis to a benevolent God in a bilateral Manichean struggle. In popular fiction evil takes the form of the slasher, the serial killer, the bogeyman, the ogre, the Joker, the James Bond villain, or depending on the cinematic decade, the Nazi officer, Soviet spy, Italian gangster, Arab terrorist, inner-city predator, Mexican druglord, galactic emperor, or corporate executive. The evildoer may enjoy money and power, but these motives are vague and ill formed; what he really craves is the infliction of chaos and suffering on innocent victims. The evildoer is an adversary—the enemy of good—and the evildoer is often foreign. Hollywood villains, even if they are stateless, speak with a generic foreign accent.
The myth of pure evil bedevils our attempt to understand real evil. Because the standpoint of the scientist resembles the standpoint of the perpetrator, while the standpoint of the moralizer resembles the standpoint of the victim, the scientist is bound to be seen as “making excuses” or “blaming the victim,” or as trying to vindicate the amoral doctrine that “to understand all is to forgive all.” (Recall Lewis Richardson’s reply that to condemn much is to understand little.) The accusation of relativizing evil is particularly likely when the motive the analyst imputes to the perpetrator appears to be venial, like jealousy, status, or retaliation, rather than grandiose, like the persistence of suffering in the world or the perpetuation of race, class, or gender oppression. It is also likely when the analyst ascribes the motive to every human being rather than to a few psychopaths or to the agents of a malignant political system (hence the popularity of the doctrine of the Noble Savage). The scholar Hannah Arendt, in her writings on the trial of Adolf Eichmann for his role in organizing the logistics of the Holocaust, coined the expression “the banality of evil” to capture what she saw as the ordinariness of the man and the ordinariness of his motives.42 Whether or not she was right about Eichmann (and historians have shown that he was more of an ideological anti-Semite than Arendt allowed), she was prescient in deconstructing the myth of pure evil. 43 As we shall see, four decades of research in social psychology—some of it inspired by Arendt herself—have underscored the banality of most of the motives that lead to harmful consequences.44
In the rest of this chapter I’ll lay out the brain systems and motives that incline us toward violence, while trying to identify the inputs that ramp them up or down and thereby offer insight into the historical decline of violence. Appearing to take the perspective of the perpetrator is just one of the dangers that attends this effort. Another is the assumption that nature organized the brain into systems that are morally meaningful to us, such as ones that lead to evil and ones that lead to good. As we shall see, some of the dividing lines between the inner demons of this chapter and the better angels of the next were guided as much by expository convenience as by neurobiological reality, because certain brain systems can cause both the best and the worst in human behavior.
