1) Hall pointed out a move by Locke: Africans did the enslaving via right of conquest; Europeans just bought the enslaved. But this makes enslavement into a essential property attributed once and for all to a subject, whereas Hall reminded us that in reality enslaving was a continually re-worked process through countless daily practices of humiliation and torture.
2) In her discussion of a landscape description in Long's History of Jamaica she pointed out how, behind a waterfall, there was a grotto where maroons could hide.
4) Long's continual disavowal of the humanity of slaves was particularly acute in describing the tortuous execution of rebels, whose agonies were disavowed with a claim that they didn't really suffer all that much.
I didn't get to make a comment at the talk, but if I had it would have been this:
5) But this disavowal renders inexplicable the practice of public torture with the aim of terrorizing the gathered slaves: if the tortured didn't really suffer all that much due to their sub-human nature, then what was the use of gathering the others? They could only be terrorized by sharing the pain of the tortured, but that pain is what was disavowed.
