we did descend from this guy, john cashin, but inconveniently he was a slave owner. he a slave owner, the father of my great-grandfather -- >> hershel father. >> hershel's father. but that guy's father was also named john was one of the more prominent slaveowners in augusta. so here i have to contend with not only did i see -- not only did i descend from slavery, but from considerable wealth born of slavery, and i could tie my family's history of relative advantage, you know, for generations of educated people. my great-grandfather had a classical education in philadelphia, and became a lawyer. i could tie that to wealth in slavery which was new. i reconciled myself to that history by what my grandfather, great-grandfather chose to do with it. he chose to go back to the south, which he didn't have to, and he chose to work for the uplift in people of color. he chose to identify with people of color when, in fact, several of his siblings were pale enough to pass, and they did pass. so he was a bit of an agitator as well. that was one thing i discovered. >> professor cas
