This article uses Peirce's Critical Common-sensism to conduct social critical inquiry into racism and “colorblindness” in the U.S. I argue that “colorblindness” discourse - in its sincere, but naïve form - is an enactment of paper-doubt, where racist common-sense beliefs are supposedly eradicated, but still function unintentionally. I offer a Peircean challenge to the common dismissal of people of color's testimony regarding the prevalence of racism. Since people of color experience racism-based secondness often not experienced by whites, their testimony must (...) be embraced as indispensable to the elimination of racist belief-habits. (shrink)
