The book I bought and then lost was Judith Shapiro, Community of Scholars.
Badiou has a book or essay called “Vat is een volk?” that I should read.
Michael North’s book The Baltic would be worth reading. So would Lefebvre, Marxist theory and the city.
Kant’s 1764 observations on feeling; the sublime and the beautiful; have to do with race; so does the origin of the 3d critique on aesthetics; mestizaje was supposed to improve the looks of women; these ideas have something to do with the Caucasus that I must reconstruct.
There was Georg Foster, who traveled with Captain Cook, and attempted to understand the concept of races, apparently said there were no races (this is something to be verified).
See also Arendt on Kant’s 3d critique, and Kant’s introduction to Anthropology. It is from Kant’s discussion of the inner and outer judge that some of these ideas about race come; also, the idea of natural science and teleological nature come from the debate on race.
