Presaging the disparities that led to mass incarceration in our era, the abolitionist minister William Goodell observed the quandary of black people in antebellum America. “He is accounted criminal for acts which are deemed innocent in others,” Goodell wrote in 1853, “punished with a severity from which all others are exempted. He is under the control of the law, though unprotected by the law, and can know law only as an enemy.

Throughout human history, three caste systems have stood out. The tragically accelerated, chilling, and officially vanquished caste system of Nazi Germany. The lingering, millennia-long caste system of India. And the shape-shifting, unspoken, race-based caste pyramid in the United States. Each version relied on stigmatizing those deemed inferior to justify the dehumanization necessary to keep the lowest-ranked people at the bottom and to rationalize the protocols of enforcement. A caste system endures because it is often justified as divine will, originating from sacred text or the presumed laws of nature, reinforced throughout the culture and passed down through the generations.

Our era calls for a public accounting of what caste has cost us, a Truth and Reconciliation Commission, so that every American can know the full history of our country, wrenching though it may be. The persistence of caste and race hostility, and the defensiveness about anti-black sentiment in particular, make it literally unspeakable to many in the dominant caste. You cannot solve anything that you do not admit exists, which could be why some people may not want to talk about it: it might get solved.
