Indeed, this was a very interesting discussion. I think Weber’s insights are certainly prescient. This might be why there was a rise of communitarianism among Anglo-American Philosophers (Sandel, Walzer, MacIntyre); and perhaps why contemporary thinkers in Continental Europe felt that Marxism did not address issues of Gender and Race.
Before we conclude our discussion, I would like to voice for the last time my opinion on the concept of race. I think your example of slavery is actually a good case for my argument. If you take a look at our relationship with slavery, you will find that it is very superficial. We throw empty remarks about the horrors of slavery, but almost no one has read or learned about slavery beyond grade school. For the younger generation it is worse: they have often never seen footages of how the media portrayed Black people in the 20th century. They regard such overt racism as merely relics of the past. But, as someone who’s lived in the South for quite some time, it is still very much alive. This is why I am wary of relegating the concept of race to a merely historical one. Our culture has shown to regard this part of our history with superficiality.
History is a choice. We choose to remember which events defined our history. This is why we don’t talk about how Susan from Mississippi in the 1800s woke up everyday. I regard slavery and race as fundamental features of our history that cannot be treated like Susan from Mississippi. I presume that you would not argue for this either. My fear, though, is that we are too eager to relegate it to something more like Susan from Mississippi. We do not want to look at ourselves as descendants of such horror. Nonetheless, despite our disagreements I had a lot of fun. Hopefully, we continue to think and learn more about these issues — and to engage those from different groups with nuance and care.
