Based on a review of the literature and historical evidence, I argue that the use of the methodological principle known as the priority principle in Anglo-American Nietzsche scholarship is inconsistent and irreconcilable with historical evidence. It attempts to demarcate between the published works and the Nachlass. However, there are no agreed upon necessary and sufficient conditions of a particular textual object being considered “Nachlass.” This absence leads to implicit and often tacit value demarcation criteria that can be broadly grouped into (...) four types of consideration: publication, authorization, publicness, and audience. Each of these criteria pick out a different set of texts as “Nachlass.” Thus, despite the veneer of agreement, the most broadly accepted methodological approach in the Anglo-American tradition of Nietzsche scholarship is applied inconsistently. I argue that we must either offer necessary and sufficient conditions for a piece of text being Nachlass, or we ought to abandon such abstract criteria altogether and embrace a contextual and historical approach. I then argue that the first option is impossible given historical evidence. I conclude this article by explicating several recent German approaches to the Nachlass which I think can offer a new possible approach. (shrink)
