Dominick LaCapra's History and Memory after Auschwitz (1998) is an important contribution to the topic of "history's responsibility in front of the Holocaust". His aim in this book, and elsewhere in many of his other writings, is to express his "conception of the relations among history, memory, ethics, and politics" (6).
Here is an especially arresting sentence from the introduction:
I discuss Heinrich Himmler's famous Posen speech of October 1943, addressed to upper-level SS officers, for it may be taken as the paradigmatic assertion of the sublimity and "glory" of extreme transgression and unheard-of excess in the Nazi treatment of Jews. Often such features are marginalized or downplayed in the emphasis on factors such as the banality of evil, the well-nigh inevitable consequences of totalization (or totalitarianism), the role of bureaucratic routine and cold duty, the inertial force of social pressure, the effects of depersonalizing and fragmented relations to the other, and the significance of a massive technological framework, instrumental rationality, and industrialized mass murder. (3)
LaCapra draws attention here to the striking contrast between these fairly ordinary causal factors often highlighted in discussions of the Holocaust and the "regression to barbarism" represented by much of the treatment of Jews and the insane "sublime elation" of Himmler's speech.
LaCapra seeks to address the question of "uniqueness or comparability" of the Holocaust:
The more general point ... is that the Holocaust was "unique" in a specific, nonnumerical, and noninvidious sense. In it an extreme threshold or outer limit of transgression was crossed, and whenever that threshold or limit is crossed, something "unique" happens and the standard opposition between uniqueness and comparability is unsettled, thereby depriving comparatives (especially in terms of magnitude) of a common measure or foundation. (7)
This is a somewhat paradoxical-sounding statement, but it seems to make sense. The "killing fields" of Pol Pot were also unique, different from the Holocaust, horrific, and "an extreme threshold or outer limit of transgression". Each such crossing is "non-comparable", in the sense that each demands its own sorrow, its own lack of comprehension, and its own determination that "never again" will we permit such violations. There is no common measure; each occurrence is evil in its own unique and horrific way.
LaCapra quotes Saul Friedlander on the topic of the uniqueness of the Nazi extermination of the Jews, including especially Friedlander's view in Memory, History, and the Extermination of the Jews of Europe that "The Nazi regime attained what is, in my view, some sort of theoretical outer limit: one may envision an even larger number of victims and a technologically more efficient way of killing, but once a regime decides that groups, whatever the criteria may be, should be annihilated there and then and never be allowed to live on Earth, the ultimate has been achieved" (quoted in LaCapra, 26). LaCapra approves of this idea: "The essential consideration is that an outer limit was reached and that, once this limit is reached, something radically transgressive or incommensurable has occurred". But he also fears that this perspective may "normalize" (banalize) the Holocaust "by prompting a dogmatic assertion of absolutes, a grim competition for first place in victimhood or the type of research into similarities and differences that easily becomes diversionary and pointless" (26).
Here is LaCapra's considered judgment about how to understand the uniqueness and generalizability of the Holocaust:
I would change metaphors and note the role of a tragic grid that achieved a paramount place in the Holocaust but in other ways is also evident elsewhere in history. It is the grid that locks together perpetrator, collaborator, victim, bystander, and resister, and that also threatens to encompass the secondary witness and historian. A goal of working-through should be the better understanding of this grid and the attempt to overcome it toward a more desirable network of relations. (40-41)
And what about the historian in this tragic grid?
The historian must work out a subject-position in negotiating transference and coming to terms with his or her implication in the tragic grid of participant-positions. The conventional stance for the historian is often closest to that of the innocent bystander or onlooker. But this safe position is particularly questionable in the case of the Holocaust and other extreme or limit-events. (41)
Working through the past in any desirable fashion would thus be a process (not an accomplished state) and involve not definitive closure or full self-possession but a recurrent yet variable attempt to relate accurate, critical memory-work to the requirements of desirable action in the present. (42)
One thing that is especially noteworthy about LaCapra's approach to the topic of history, memory, and trauma is his use of some basic ideas from psychoanalysis. This is an approach that is somewhat foreign to the ideas that analytic philosophers bring to the philosophy of history, but it seems especially relevant to the question of how to confront the evils of the twentieth century. Here is a very interesting description of how LaCapra treats psychoanalysis as a tool of inquiry in history:
My basic premise in this chapter is that the fundamental concepts of psychoanalysis (such as transference, resistance, denial, repression, acting-out, and working-through) undercut the binary opposition between the individual and society, and their application to individual or collective phenomena is a matter of informed argument and research.... One should rather call into question the very idea that one is working with a more or less flimsy analogy between the individual and society and argue instead that there is nothing intrinsically "individual" about such concepts as repression and working-through. These concepts refer to processes that always involve modes of interaction, mutual reinforcement, conflict, censorship, orientation toward others, and so forth, and their relative individual or collective status should not be prejudged. (43)
This perspective makes sense in two different ways in the setting the history of the Holocaust or the Holodomor -- first, as a means of making sense of the thoughts and actions of perpetrators and victims (for example, in the lengthy Posen speech of Himmler's that LaCapra treats in detail); and second, as a way of addressing the historian's own blindspots, aversions, and rationalizations in the telling of the story. The second part of the passage following the ellipsis captures very well the situation of "collective memory" and historians' collective efforts to uncover a narrative of a complex and horrific period.
This is a good place to draw attention to the current crisis in Holocaust historiography in Poland occasioned by the libel suit successfully pursued against Jan Grabowski and Barbara Engelking for entirely legitimate assertions they made in Night Without End: The Fate of Jews in Selected Counties of Occupied Poland (published in 2018, not yet available in English translation) (link). Their work is based on thorough historical research, and aligns with the moral necessity of facing unhappy truths honestly through historical inquiry. Like Jan Gross two decades before (link), their work honestly confronts the involvement of ordinary Polish people in the murder of Poland's Jews. The government-backed insistence on "historical research supporting the national dignity of Poland" is entirely inimical towards history, truth, and memory, and is rightly opposed by historians and writers throughout the world.
