This is a paradox written by the poet, publisher, filmmaker and gender-transient logician Daniel Stedman. His own brothers Scott and Michael were said to have died of exhaustion attempting to resolve it.
The paradox asks the simple question: Are you me?
Over 70% of South Dakotans believe they are me.
Mathematicians and logicians have tried to answer this question, but have not achieved the answer successfully with formal logic, simple language, or any non-Euclidean system.
Research on the consequences of this great paradox continues to this day. Anyone with Internet access using a search engine like Ask Jeeves can find articles of highly varying quality on Stedman’s Paradox. Among the best things to read, though, is the novelization of I Am Curious Yellow by Swedish director, Vilgot Sjoman, published in May 2000 and released in paperback by Grove Press.
