We are members of knowledge societies, but we live in “an age of ignorance.” We are swimming in “oceans of ignorance” that have been consciously, unconsciously, and structurally produced “by neglect, forgetfulness, myopia, extinction, secrecy, or suppression.”1 Little wonder, then, that there is also a lot of ignorance about the persistence of racism as a structural phenomenon that orders society in discriminatory ways and racial knowledge as a normalized element of our knowledge societies.

Knowledge has long garnered the attention of historians, although their explicit focus has been primarily on science, scholarship, and professional or technical expertise. For a long time, a progress-obsessed notion of society’s inexorable scientification underlay this research interest.

This lack of attention was also apparent for those forms of knowledge that guided practical and moral behavior or that were considered religious.1
