When Bertrand Russell alerted Gottlob Frege to an inconsistency in his Grundgesetze, Frege relinquished deep commitments. When Edward Evans-Pritchard alerted the Azande to an inconsistency in their beliefs about witchcraft inheritance, they did not revise their beliefs. Nor did they engage in the defensive maneuvers depicted in Plato’s dialogues. Evans-Pritchard characterized their indifference to contradiction as irrational. My historical thesis is that the ensuing anthropological debate mirrors the debate about the sorites paradox. I favor a simple explanation of this parallelism: (...) Evans-Pritchard’s witchcraft inheritance argument is a sorites argument—albeit in a form masked by the different ontologies of the Azande and Evans-Pritchard. Evans-Pritchard failed to recognize his witchcraft inheritance argument as a sorites paradox because he was witchcraft nihilist in a community of witchcraft realists. My general conjecture is that many of the irrationalities that seem distinctive of alien cultures are actually paradoxes that are universal. The irrationality of the aliens is real and profound; it is just not distinctive of those aliens or their cultures. The universality of the irrationality helps to explain Evans-Pritchard’s surprising success at understanding the Azande. Since he shares their core irrationality, Evans-Pritchard could simulate Azande thinking. Although I am attributing an anthropological illusion to Evans-Pritchard, I think it is one that coheres nicely with his compelling account of Azande. I am a conservative follower of Evans-Pritchard, trying to debug his research programme. I endorse all of his central doctrines and I rely on his insights. (shrink)
