My impression about the response of philosophers to the holocaust, is that they popularized postmodernism because of it. The postmodernists reasserted subjectivity over the pretended objectivity of racial pseudoscience of the nazis.
The postmodernists do not strictly validate the concept of subjectivity, they do not explain how subjectivity works, instead postmodernists just assume it from common knowledge, and assert that facts in general are tainted with some subjective aspects. So to soften the hardedged materialism somewhat, with some emotion. And this works to some extent.
The holocaust has gained some quasireligious meaning for especially Western societies, or the history that includes scientific and technological progress. Currently the lesson drawn from the history of the holocaust is focused much on punishing hatespeech. Which is a very outrageous and wrong interpretation of the history in my opinion. That people are now put in jail for some remark they make on the internet, is I believe, mainly because of this interpretation. So that the holocaust has become the main reason for wideranging surpression of free speech.
The story that nazi ideology is based on hate, is an error. Instead the main characteristic of nazi ideology is emotionless calculating judgment on the personal character of people, asserted as fact of racial science. So nazism should be thought of as marginalizing all emotions, including also hate.
Hate is really just an ordinary human emotion. There is danger associated to it, on the other hand identities can’t really prosper if you are only allowed to express appreciation about the identity, and aren’t allowed to mention anything you don’t like about it. In that case people prefer not to talk about the identity at all, ignore it altogether, and the identity withers. So there is general loss of identity, by surpressing hatespeech.
The very obvious lesson that should be drawn from the holocaust instead, is to learn the logic of fact and opinion, a simple school lesson.
It was an error of the nazis to assert that personal character can be established as fact, instead personal character is identified with a chosen opinion. As for example, it is a chosen opinion to say “Trump is a nice man”. That opinion says something about Trump, but it also says something about the person who chose that opinion, because this person chose the opinion from their own emotions and personal character.
I should say though that even with the correct interpretation that personal character is esssentially identified with a chosen opinion, this still leaves a theoretical opening for racism which asserts that there is some objective heritable organization of decision-making processes. For example to say someone has the heritable organization of decision-making processes that are similar to that of a pig, which is a very racist thing to say.
But I think the evidence shows that it is mainly and only the marginalization of subjectivity in nazi ideology which carries the evil load of it. Which is because that part has by far the biggest motive behind it, and for a crime you need a big motive. Which big motive is the psychological pressure to do your best.
This psychological pressure to do your best occasions people to conceive of choosing in terms of selection of options (selection of the best option). And that is where it all goes wrong, because the concept of subjectivity requires “choosing” to be defined in terms of spontaneity, in order for the concept of subjectivity to function. So the underlying reason for why nazis incorrectly objectified personal character with racial science, is because they had no functioning concept of subjectivity to begin with. Nazis were essentially “selectionists”, which means, people who conceive of choosing in terms of selection of options, instead of conceiving of it in terms of spontaneity.
In the mind of a selectionist, the decisions they make refer back to the values that they used to evaluate the options with. Their decisions do not refer back to their emotions. The emotions being cut off, therefore the emotions become morbid. And then these selectionists compensate for these morbid emotions, by generating more feelings of doing their best, which feelings are associated to their idea of choosing in terms of selection of the best option.
So typically a nazi would be very full of the feelings of doing their best, but the normal emotions, like for family, are much marginalized and instrumentalized to the background, and morbid. The genocides were then conceived of in terms of what the nazis called, the socialistic process of selection, which meant wiping out the less worthy, and preservation of the best. But the main motor behind all this is the exaggeration of policy, which exaggeration serves to generate more feelings of doing their best, for their own emotional survival. That is what makes the policies extreme out of all proportion.
Another aspect of this is, that when someone conceives of choosing in terms of selection of the best option, which is actually very common to do, then any decision they make is by their own definition of the verb “choose”, automatically doing their best, regardless of what they choose. So that conscience is much circumvented. If you would ask a nazi about their crimes, then this analysis predicts that they would respond that they were doing their utmost best.
Learning the logic of fact and opinion, would fundamentally undermine the error of selectionism. Because in the logic of opinion it would be explained that choosing is in fact spontaneous, and that selection of options is a valid but different idea from choosing. Spontaneous meaning that a decision can turn out one way or another in the moment that a decision is made.
The logic of fact and opinion is explained with creationism. Science is limited to facts, which idea of fact is validated by materialism. Opinions, like opinions on beauty, are outside of science. The two fundamental categories of creator and creation are required to validate both concepts of opinion and fact respectively.
Creationism: What is subjective, creates what is objective, by decision. As for example, the baby (objective) was born from love (subjective), or, God (subjective) created the earth (objective).
- Creator / chooses / spiritual / subjective / opinion
- Creation / chosen / material / objective / fact
subjective = identified with a chosen opinion
objective = identified with a model of it
Personal character would be classified in category 1, because decisions are made out of personal character. Therefore personal character is identified with a chosen opinion. Which shows exactly why it is wrong to objectify personal character.
While this logic is very simple, it is psychologically a very hard lesson. It is hard for people to accept the fact that decisions are spontaneous. However the logic shows that you cannot have a functioning concept of subjectivity otherwise.
