Rationality is this process of faking it, and it is always secured through violence. Rene Descartes, one of the fathers of rationalism, even defines it as transforming intellectual uncertainty into certainty. But this certainty is only ever an idea; the social world is never certain. So when people like Michael Brown, Eric Garner, or Trayvon Martin—or places like Ferguson, Missouri; Baltimore, Maryland; or Cleveland, Ohio—cause a person to feel uncertain, when black bodies trouble the “rational” order of things, they get killed.
