Applying the Deluzoguattarian concept of the trace, this article explores interactions between a White teacher and his Black students and the way race is coconstructed therein. Using a short story by the Argentine mystery writer Jorge Luis Borges as a frame, the author connects the poststructural philosophy of the trace to current notions of postracial color blindness. His own experience, however, as demonstrated through autoethnographic sketches, is posited as experiential evidence that contests the chimerical nature of such color-blind claims. A caesura, rather than a conclusion, is reached through a gloss of an episode of the television series "Seinfeld." The author believes this piece of pop culture demonstrates the tensions existing between the idealism of postracial color blindness and the realities of the trace. (Contains 16 notes.)
