Caste is a disease, and none of us is immune.

In addition to restating one of the key assertions of Caste, that caste affects everyone at every level of its hierarchy, this quote from the epilogue picks up on the book’s frequent comparison of caste with disease. It echoes Wilkerson’s earlier comparison of social history to a person’s medical history in The Vitals of History in Part One, underlining the importance of acknowledging and treating disease rather than ignoring it. More literally, Wilkerson is also alluding to the actual dangers that caste poses to the health of its subjects, which she outlines in multiple chapters throughout Parts Five and Six.
